    EULAR/ERA-EDTA recommendations for the management of ANCA-associated vasculitis2016In: Annals of the Rheumatic Diseases, ISSN 0003-4967, E-ISSN 1468-2060, Vol. 75, no 9, p. 1583-1594Article, review/survey (Refereed)
    Abstract [en]

    In this article, the 2009 European League Against Rheumatism (EULAR) recommendations for the management of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) have been updated. The 2009 recommendations were on the management of primary small and medium vessel vasculitis. The 2015 update has been developed by an international task force representing EULAR, the European Renal Association and the European Vasculitis Society (EUVAS). The recommendations are based upon evidence from systematic literature reviews, as well as expert opinion where appropriate. The evidence presented was discussed and summarised by the experts in the course of a consensus-finding and voting process. Levels of evidence and grades of recommendations were derived and levels of agreement (strengths of recommendations) determined. In addition to the voting by the task force members, the relevance of the recommendations was assessed by an online voting survey among members of EUVAS. Fifteen recommendations were developed, covering general aspects, such as attaining remission and the need for shared decision making between clinicians and patients. More specific items relate to starting immunosuppressive therapy in combination with glucocorticoids to induce remission, followed by a period of remission maintenance; for remission induction in life-threatening or organ-threatening AAV, cyclophosphamide and rituximab are considered to have similar efficacy; plasma exchange which is recommended, where licensed, in the setting of rapidly progressive renal failure or severe diffuse pulmonary haemorrhage. These recommendations are intended for use by healthcare professionals, doctors in specialist training, medical students, pharmaceutical industries and drug regulatory organisations.

    Validation of the EULAR/ERA-EDTA recommendations for the management of ANCA-associated vasculitis by disease content experts2017In: RMD open, ISSN 2056-5933, Vol. 3, no 1, article id e000449Article in journal (Refereed)
    Abstract [en]

    The European League Against Rheumatism recommendations for the management of antineutrophil cytoplasmic antibody-associated vasculitis have been recently published. Unique to recommendation development, they were also voted on by members of a learned society. This paper explores the wider validity of the recommendations among people who self-identify as clinicians caring for patients with vasculitis. In addition to the task force, a learned society (European Vasculitis Society-EUVAS) was invited, through online survey, to rate independently the strength of evidence of each recommendation to obtain an indication of the agreement among the final target audience and ultimate end-users of the recommendations. The survey took place in June 2015. Of the 158 EUVAS members surveyed, there were 88 responses (55.7%). There was a large degree of agreement in the voting patterns between EUVAS survey participants and task force members. Notable exceptions were lower grades for the recommendation of the use of rituximab for remission induction in patients with eosinophilic granulomatosis with polyangiitis and for methotrexate and mycophenolate mofetil as remission maintenance agents in patients with granulomatosis with polyangiitis/microscopic polyangiitis by EUVAS members. These results are encouraging and suggest that the voting patterns of the task force are representative of the wider vasculitis community. We recommend future recommendations adopt this approach for data/expert-based treatment guidelines, especially for multisystem diseases.

    Life in standby: hemodialysis patients' experiences of waiting for kidney transplantation.2016In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 25, no 1-2, p. 92-98Article in journal (Refereed)
    Abstract [en]

    AIM AND OBJECTIVES: Our aim was to explore the experiences of hemodialysis patients who are waiting for a kidney transplant.

    BACKGROUND: Currently, more than 100,000 persons are waiting for kidney transplantation in the United States. In Sweden, the number is exceeding 600. The waiting period for a deceased donor can be one to three years or even longer in Sweden. This can be challenging, since the patients' situation, with chronic treatment and illness, is burdensome and requires advanced self-care.

    DESIGN: This study included a purposeful sample of eight patients (33-53 years old) who had been undergoing hemodialysis treatment for at least six months and were waiting for kidney transplantation.

    METHODS: The patients were interviewed, and descriptive content analysis was performed.

    RESULTS: Four categories emerged: (1) 'The waiting process,' what thoughts and expectations occur and what to do and how to be prepared for the transplant. (2) 'Awareness that time is running out,' patients felt tied up by treatment and by needing to be available for transplantation, and they had concerns about health. (3) 'Need for communication,' patients described needing support from others and continuous information from the staff. (4) 'Having relief and hope for the future,' patients described how to preserve the hope of being able to participate fully in life once again.

    CONCLUSIONS: This study reveals the need for extra attention paid to patients waiting for kidney transplantation. Patients' experiences during the waiting period indicate that pretransplant patients have an increased need to be prepared for the transition and for life post-transplantation.

    RELEVANCE TO CLINICAL PRACTICE: Dialysis patients on waiting lists must be prepared for the upcoming life change. This includes preserving hope during the waiting period and being mentally prepared for transplantation and a dialysis-free life. A pretransplant education program to prevent medical and psychosocial issues is highly recommended.

    The Act1 D10N missense variant impairs CD40 signaling in human B-cells2019In: Genes and Immunity, ISSN 1466-4879, E-ISSN 1476-5470, Vol. 20, no 1, p. 23-31Article in journal (Refereed)
    Abstract [en]

    The TRAF3IP2 gene resides within one of at least 63 psoriasis susceptibility loci and encodes Act1, an adapter protein involved in IL-17 receptor and CD40 signaling pathways. TRAF3IP2 is distinctive (among amp;lt; 10% of candidate susceptibility genes) in that a strongly disease-associated variant encodes a missense SNP predicted to be functionally relevant (SNP rs33980500 C/T encoding Act1 pD10N). As assessed by flow cytometry, Act1 protein was expressed at the highest levels in monocytes, with lower levels in T-cells and B-cells. However, monocytes, T-cells and B-cells failed to respond to IL-17A stimulation of PBMC, as measured by flow cytometric determination of NF-kappa B phospho-p65. As an alternative stimulus, we treated PBMCs with trimerized recombinant human CD40L and assessed p65, p38 and Erk phosphorylation in CD19(+) B-cells as a function of D10N genotype. The increase of phosphorylated p65, p38, and Erk was well-correlated across individuals, and CD40L-induced phosphorylation of p65, p38, and Erk was significantly attenuated in B-cells from Act1 D10N homozygotes, compared to heterozygotes and nullizygotes. Our results indicate that the Act1 D10N variant is a relevant genetic determinant of CD40L responsiveness in human B-cells, with the risk allele being associated with lower B-cell responses in an acute signaling context.

    Autophagy Induction Protects Against 7-Oxysterol-induced Cell Death via Lysosomal Pathway and Oxidative Stress2016In: Journal of cell death, ISSN 1179-0660, no 9, p. 1-7Article in journal (Refereed)
    Abstract [en]

    7-Oxysterols are major toxic components in oxidized low-density lipoprotein and human atheroma lesions, which cause lysosomal mem-brane permeabilization (LMP) and cell death. Autophagy may function as a survival mechanism in this process. Here, we investigated whether 7-oxysterols mixed in an atheroma-relevant proportion induce autophagy, whether autophagy induction influences 7-oxysterol-mediated cell death, and the underlying mechanisms, by focusing on cellular lipid levels, oxidative stress, and LMP in 7-oxysterol-treated macrophages. We found that 7-oxysterols induced cellular lipid accumulation, autophagy dysfunction, and cell death in the form of both apoptosis and necrosis. Exposure to 7-oxysterols induced autophagic vacu-ole synthesis in the form of increased autophagy marker microtubule-associated protein 1A/1B-light chain 3 (LC3) and LC3-phosphatidylethanolamine conjugate (LC3-II) and autophagic vacuole formation. This led to an accumulation of p62, indicating a reduction in autophagic vacuole degradation. Importantly, autophagy induction significantly reduced 7-oxysterol-mediated cell death by diminishing LMP and oxidative stress. Moreover, autophagy induction minimized cellular lipid accumulation induced by 7-oxysterols. These findings highlight the importance of autophagy in combating cellular stress, LMP, and cell death in atherosclerosis. Therefore, activation of the autophagy pathway may be a potential therapeutic strategy for prevention of necrotic core formation in atherosclerotic lesions.

    Carotid Atheroma From Men Has Significantly Higher Levels of Inflammation and Iron Metabolism Enabled by Macrophages2018In: Stroke, ISSN 0039-2499, E-ISSN 1524-4628, Vol. 49, no 2, p. 419-425Article in journal (Refereed)
    Abstract [en]

    Background and Purpose-Men differ from women in the manifestation of atherosclerosis and iron metabolism. Intraplaque hemorrhage and hemoglobin (Hb) catabolism by macrophages are associated with atherosclerotic lesion instability. The study aims were to investigate sex differences in (1) lesion severity in relation to blood Hb, (2) iron homeostasis in human carotid plaques, and (3) macrophage polarization within atheroma. Methods-The carotid artery samples from 39 men and 23 women were immunostained with cell markers for macrophages, smooth muscle cells, ferritin, and TfR1 (transferrin receptor 1), which were further analyzed according to sex in relation to iron, Hb, and lipids in circulation. Additionally, samples of predefined regions from human carotid atherosclerotic lesions, including internal controls, were used for proteomic analysis by mass spectrometry. Results-Male patients, compared with women, had larger necrotic cores and more plaque rupture, which were associated with higher levels of Hb. Atheroma of male patients had significantly higher levels of Hb in circulation and CD68 macrophages, ferritin, and TfR1 in lesions. CD68 macrophages were significantly correlated with ferritin and TfR1. Plaques from male patients comparatively possessed higher levels of inflammatory macrophage subsets, CD86 (M1) and CD163 (M2), but lower levels of STF (serotransferrin) and HPX (hemopexin). Conclusions-Male patients with carotid atheroma had more advanced and ruptured lesions associated with significantly higher levels of inflammatory macrophage infiltration and high iron stores in the blood and in their plaques. These findings help to understand sex differences and iron metabolism in atherosclerosis and factors related to atheroma progression.

    Estimation of Superficial Venous Reflux with Duplex Ultrasound and Foot Volumetry2019In: Juniper Online Journal of Case Studies, ISSN 2476-1370, Vol. 10, no 1, p. 1-5, article id 555776Article in journal (Refereed)
    Abstract [en]

    Objective: To evaluate quantitative duplex ultrasound (DUS) parameters of reflux in patients with isolated great saphenous vein insufficiency.

    Methods: 20 limbs were studied. DUS derived reflux time (RT, sec), peak reflux velocity (PRV, cm/s) and reflux volume flow (ml/min) were evaluated and related to expelled volume (EV, ml) and half refilling time (T50, sec) measured by water-based foot volumetry with and without compression of superficial veins.

    Results: Reflux volume flow correlated significantly to all hemodynamic parameters assessed by foot volumetry, i.e., EV (p = 0.003), ΔEV (p = 0.006), T50 (p = 0.004) and ΔT50 (p = 0.011). PRV displayed a weaker correlation to foot volumetry parameters EV (p = 0.027) and T50 (p = 0.008). No significant correlation was found between RT and foot volumetry.

    Conclusion: These results indicate that reflux volume flow may be a potential parameter in future attempts to quantify reflux using DUS in patients with isolated great saphenous vein insufficiency.

    An extended high-frequency ultrasound protocol for detection of vessel wall inflammation.2018In: Clinical Physiology and Functional Imaging, ISSN 1475-0961, E-ISSN 1475-097X, Vol. 38, no 4, p. 586-594Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The aim of this study was to evaluate an extended protocol of the large vessels using high-frequency duplex ultrasound (DUS) for detection of vessel wall inflammation.

    METHODS: Fifty-eight patients performed a DUS examination where arteritis could not be excluded. All DUS examinations were performed using ACUSON S2000 TM ultrasound system (Siemens Medical Solutions USA, Inc.). High-frequency linear transducers were used (18L6 MHz, 9L4MHz) or curve linear for the aortic arch (6C2 MHz). Carotid, vertebral, central neck arteries (subclavian, axillary, innominate) arteries, aortic arch and femoral arteries were studied. Circumferential, homogenous wall thickening, with or without a hyperechogenic stripe lining the innermost layer, were regarded as typical signs of arteritis. Intima-media thickness (IMT) was measured in the patients and a normal control group. The latest clinical updated diagnosis was assessed at least 6 months after DUS.

    RESULTS: The DUS findings showed normal vessels (n = 14), arteritis and atherosclerosis (n = 13), atherosclerosis (n = 15) and arteritis (n = 16). The latter group had a significant increased IMT in the common femoral artery and the common carotid artery (mean 1·0 ±  SD 0·3 mm versus 0·6 ± 0·2 mm in the normal group (n = 37), P<0·00001, 1·2 ± 0·5 mm versus 0·8 ± 0·2 mm in the normal group (n = 40), P<0·00001). In the groups with sonographic signs implying arteritis (n = 29), 20 patients had a clinical diagnosis of arteritis, whereas eight patients had another main diagnosis such as malignancy/other inflammatory or infectious disease complicated by inflammation of the vessel wall. One patient had multiple diagnoses and was not possible to classify.

    CONCLUSION: An extended ultrasound protocol for central neck and leg arteries could be of value for diagnosis of arteritis. In case of atypical vessel wall inflammation, other main diagnoses should be considered.

    Mechanical dyssynchrony alters left ventricular flow energetics in failing hearts with LBBB: a 4D flow CMR pilot study.2018In: The International Journal of Cardiovascular Imaging, ISSN 1569-5794, E-ISSN 1875-8312, Vol. 34, no 4, p. 587-596Article in journal (Refereed)
    Abstract [en]

    The impact of left bundle branch block (LBBB) related mechanical dyssynchrony on left ventricular (LV) diastolic function remains unclear. 4D flow cardiovascular magnetic resonance (CMR) has provided reliable markers of LV dysfunction: reduced volume and kinetic energy (KE) of the portion of LV inflow which passes directly to outflow (Direct Flow) has been demonstrated in failing hearts compared to normal hearts. We sought to investigate the impact of mechanical dyssynchrony on diastolic function by comparing 4D flow in myopathic LVs with and without LBBB. CMR data were acquired at 3 T in 22 heart failure patients; 11 with LBBB and 11 without LBBB matched according to several demographic and clinical parameters. An established 4D flow analysis method was used to separate the LV end-diastolic (ED) volume into functional flow components based on the blood's timing and route through the heart cavities. While the Direct Flow volume was not different between the groups, the KE possessed at ED was lower in LBBB patients (P = 0.018). Direct Flow entering the LV during early diastolic filling possessed less KE at ED in LBBB patients compared to non-LBBB patients, whereas no intergroup difference was observed during late filling. Pre-systolic KE of LV Direct Flow was reduced in patients with LBBB compared to matched patients with normal conduction. These intriguing findings propose that 4D flow specific measures can serve as markers of LV mechanical dyssynchrony in heart failure patients, and could possibly be investigated as predictors of response to cardiac resynchronization therapy.

    Post-mortem 1.5T MR quantification of regular anatomical brain structures2016In: International journal of legal medicine (Print), ISSN 0937-9827, E-ISSN 1437-1596, Vol. 130, no 4, p. 1071-1080Article in journal (Refereed)
    Abstract [en]

    Recently, post-mortem MR quantification has been introduced to the field of post-mortem magnetic resonance imaging. By usage of a particular MR quantification sequence, T1 and T2 relaxation times and proton density (PD) of tissues and organs can be quantified simultaneously. The aim of the present basic research study was to assess the quantitative T1, T2, and PD values of regular anatomical brain structures for a 1.5T application and to correlate the assessed values with corpse temperatures. In a prospective study, 30 forensic cases were MR-scanned with a quantification sequence prior to autopsy. Body temperature was assessed during MR scans. In synthetically calculated T1, T2, and PD-weighted images, quantitative T1, T2 (both in ms) and PD (in %) values of anatomical structures of cerebrum (Group 1: frontal gray matter, frontal white matter, thalamus, internal capsule, caudate nucleus, putamen, and globus pallidus) and brainstem/cerebellum (Group 2: cerebral crus, substantia nigra, red nucleus, pons, cerebellar hemisphere, and superior cerebellar peduncle) were assessed. The investigated brain structures of cerebrum and brainstem/cerebellum could be characterized and differentiated based on a combination of their quantitative T1, T2, and PD values. MANOVA testing verified significant differences between the investigated anatomical brain structures among each other in Group 1 and Group 2 based on their quantitative values. Temperature dependence was observed mainly for T1 values, which were slightly increasing with rising temperature in the investigated brain structures in both groups. The results provide a base for future computer-aided diagnosis of brain pathologies and lesions in post-mortem magnetic resonance imaging.

    Temperature dependence of postmortem MR quantification for soft tissue discrimination2015In: European Radiology, ISSN 0938-7994, E-ISSN 1432-1084, Temperature dependence of postmortem MR quantification for soft tissue discrimination, Vol. 25, no 8, p. 2381-2389Article in journal (Refereed)
    Abstract [en]

    Objectives To investigate and correct the temperature dependence of postmortem MR quantification used for soft tissue characterization and differentiation in thoraco-abdominal organs. Material and methods Thirty-five postmortem short axis cardiac 3-T MR examinations were quantified using a quantification sequence. Liver, spleen, left ventricular myocardium, pectoralis muscle and subcutaneous fat were analysed in cardiac short axis images to obtain mean T1, T2 and PD tissue values. The core body temperature was measured using a rectally inserted thermometer. The tissue-specific quantitative values were related to the body core temperature. Equations to correct for temperature differences were generated. Results In a 3D plot comprising the combined data of T1, T2 and PD, different organs/tissues could be well differentiated from each other. The quantitative values were influenced by the temperature. T1 in particular exhibited strong temperature dependence. The correction of quantitative values to a temperature of 37 °C resulted in better tissue discrimination. Conclusion Postmortem MR quantification is feasible for soft tissue discrimination and characterization of thoracoabdominal organs. This provides a base for computer-aided diagnosis and detection of tissue lesions. The temperature dependence of the T1 values challenges postmortem MR quantification. Equations to correct for the temperature dependence are provided.

    Postmortem MR quantification of the heart for characterization and differentiation of ischaemic myocardial lesions2015In: European Radiology, ISSN 0938-7994, E-ISSN 1432-1084, Vol. 25, no 7, p. 2067-2073Article in journal (Refereed)
    Abstract [en]

    Recently, an MRI quantification sequence has been developed which can be used to acquire T1- and T2-relaxation times as well as proton density (PD) values. Those three quantitative values can be used to describe soft tissue in an objective manner. The purpose of this study was to investigate the applicability of quantitative cardiac MRI for characterization and differentiation of ischaemic myocardial lesions of different age. Fifty post-mortem short axis cardiac 3 T MR examinations have been quantified using a quantification sequence. Myocardial lesions were identified according to histology and appearance in MRI images. Ischaemic lesions were assessed for mean T1-, T2- and proton density values. Quantitative values were plotted in a 3D-coordinate system to investigate the clustering of ischaemic myocardial lesions. A total of 16 myocardial lesions detected in MRI images were histologically characterized as acute lesions (n = 8) with perifocal oedema (n = 8), subacute lesions (n = 6) and chronic lesions (n = 2). In a 3D plot comprising the combined quantitative values of T1, T2 and PD, the clusters of all investigated lesions could be well differentiated from each other. Post-mortem quantitative cardiac MRI is feasible for characterization and discrimination of different age stages of myocardial infarction. aEuro cent MR quantification is feasible for characterization of different stages of myocardial infarction. aEuro cent The results provide the base for computer-aided MRI cardiac infarction diagnosis. aEuro cent Diagnostic criteria may also be applied for living patients.

    Postmortem quantitative 1.5-T MRI for the differentiation and characterization of serous fluids, blood, CSF, and putrefied CSF2015In: International journal of legal medicine (Print), ISSN 0937-9827, E-ISSN 1437-1596, Vol. 129, no 5, p. 1127-1136Article in journal (Refereed)
    Abstract [en]

    The purpose of the present study was to investigate whether serous fluids, blood, cerebrospinal fluid (CSF), and putrefied CSF can be characterized and differentiated in synthetically calculated magnetic resonance (MR) images based on their quantitative T (1), T (2), and proton density (PD) values. Images from 55 postmortem short axis cardiac and 31 axial brain 1.5-T MR examinations were quantified using a quantification sequence. Serous fluids, fluid blood, sedimented blood, blood clots, CSF, and putrefied CSF were analyzed for their mean T (1), T (2), and PD values. Body core temperature was measured during the MRI scans. The fluid-specific quantitative values were related to the body core temperature. Equations to correct for temperature differences were generated. In a 3D plot as well as in statistical analysis, the quantitative T (1), T (2) and PD values of serous fluids, fluid blood, sedimented blood, blood clots, CSF, and putrefied CSF could be well differentiated from each other. The quantitative T (1) and T (2) values were temperature-dependent. Correction of quantitative values to a temperature of 37 A degrees C resulted in significantly better discrimination between all investigated fluid mediums. We conclude that postmortem 1.5-T MR quantification is feasible to discriminate between blood, serous fluids, CSF, and putrefied CSF. This finding provides a basis for the computer-aided diagnosis and detection of fluids and hemorrhages.

    Roles of piRNAs in microcystin-leucine-arginine (MC-LR) induced reproductive toxicity in testis on male offspring2017In: Food and Chemical Toxicology, ISSN 0278-6915, E-ISSN 1873-6351, Vol. 105, p. 177-185Article in journal (Refereed)
    Abstract [en]

    In the present study, we evaluated the toxic effects on the testis of the male offspring of MC-LR exposure during fetal and lactational periods. Pregnant females were distributed into two experimental groups: control group and MC-LR group which were exposed to 0 and 10 mu g/L of MC-LR, respectively, through drinking water separately during fetal and lactational periods. At the age of 30 days after birth, the male offspring were euthanized. The body weight, testis index, and histomorphology change were observed and the global changes of piwi-interacting RNA (piRNA) expression were evaluated. The results revealed that MC-LR was found in the testis of male offspring, body weight and testis index decreased significantly, and testicular tissue structure was damaged in the MC-LR group. In addition, the exposure to MCLR resulted in an altered piRNA expression profile and an increase of the cell apoptosis and a decrease of the cell proliferation in the testis of the male offspring. It was reasonable to speculate that the toxic effects on reproductive system of the male offspring in MC-LR group might be mediated by piRNAs through the regulation of the target genes. As far as we are aware, this is the first report showing that MC-LR could play a role in disorder of proliferative and cell apoptosis in the testis of the male offspring by the maternal transmission effect of toxicity.

    Roles of miRNAs in microcystin-LR-induced Sertoli cell toxicity2015In: Toxicology and Applied Pharmacology, ISSN 0041-008X, E-ISSN 1096-0333, Vol. 287, no 1Article in journal (Refereed)
    Abstract [en]

    Microcystin (MC)-LR, a cyclic heptapeptide, is a potent reproductive system toxin. To understand the molecular mechanisms of MC-induced reproductive system cytotoxicity, we evaluated global changes of miRNA and mRNA expression in mouse Sertoli cells following MC-LR treatment. Our results revealed that the exposure to MC-LR resulted in an altered miRNA expression profile that might be responsible for the modulation of mRNA expression. Bio-functional analysis indicated that the altered genes were involved in specific cellular processes, including cell death and proliferation. Target gene analysis suggested that junction injury in Sertoli cells exposed to MC-LR might be mediated by miRNAs through the regulation of the Sertoli cell-Sertoli cell pathway. Collectively, these findings may enhance our understanding on the modes of action of MC-LR on mouse Sertoli cells as well as the molecular mechanisms underlying the toxicity of MC-LR on the male reproductive system.

    Decrease in bone mineral density during three months after diagnosis of early rheumatoid arthritis measured by digital X-ray radiogrammetry predicts radiographic joint damage after one year2017In: Arthritis Research & Therapy, ISSN 1478-6354, E-ISSN 1478-6362, Vol. 19, article id 195Article in journal (Refereed)
    Abstract [en]

    Background: Periarticular osteopenia is an early sign of incipient joint injury in rheumatoid arthritis (RA), but cannot be accurately quantified using conventional radiography. Digital X-ray radiogrammetry (DXR) is a computerized technique to estimate bone mineral density (BMD) from hand radiographs. The aim of this study was to evaluate whether decrease in BMD of the hands (BMD loss), as determined by DXR 3 months after diagnosis, predicts radiographic joint damage after 1 and 2 years in patients with early RA. Methods: Patients (n = 176) with early RA (amp;lt; 12 months after onset of symptoms) from three different Swedish rheumatology centers were consecutively included in the study, and 167 of these patients were included in the analysis. Medication was given in accordance with Swedish guidelines, and the patients were followed for 2 years. Rheumatoid factor and antibodies to cyclic citrullinated peptides (anti-CCP) were measured at baseline, and 28-joint Disease Activity Score (DAS28) was assessed at each visit. Radiographs of the hands and feet were obtained at baseline, 3 months (hands only) and 1 and 2 years. Baseline and 1-year and 2-year radiographs were evaluated by the Larsen score. Radiographic progression was defined as a difference in Larsen score above the smallest detectable change. DXR-BMD was measured at baseline and after 3 months. BMD loss was defined as moderate when the decrease in BMD was between 0.25 and 2.5 mg/cm(2)/month and as severe when the decrease was greater than 2.5 mg/cm(2)/month. Multivariate regression was applied to test the association between DXR-BMD loss and radiographic damage, including adjustments for possible confounders. Results: DXR-BMD loss during the initial 3 months occurred in 59% of the patients (44% moderate, 15% severe): 32 patients (19%) had radiographic progression at 1 year and 45 (35%) at 2 years. In multiple regression analyses, the magnitude of DXR-BMD loss was significantly associated with increase in Larsen score between baseline and 1 year (p = 0.033, adjusted R-squared = 0.069). Conclusion: DXR-BMD loss during the initial 3 months independently predicted radiographic joint damage at 1 year in patients with early RA. Thus, DXR-BMD may be a useful tool to detect ongoing joint damage and thereby to improve individualization of therapy in early RA.

    Antibodies against carbamylated proteins and cyclic citrullinated peptides in systemic lupus erythematosus: results from two well-defined European cohorts.2016In: Arthritis Research & Therapy, ISSN 1478-6354, E-ISSN 1478-6362, Vol. 18, no 1Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Articular manifestations are common in systemic lupus erythematosus (SLE) whereas erosive disease is not. Antibodies to cyclic citrullinated peptide (anti-CCP) are citrulline-dependent in rheumatoid arthritis (RA), whereas the opposite is suggested in SLE, as reactivity with cyclic arginine peptide (CAP) is typically present. Antibodies targeting carbamylated proteins (anti-CarP) may occur in anti-CCP/rheumatoid factor (RF)-negative cases long before clinical onset of RA. We analysed these antibody specificities in sera from European patients with SLE in relation to phenotypes, smoking habits and imaging data.

    METHODS: Cases of SLE (n = 441) from Linköping, Sweden, and Leiden, the Netherlands, were classified according to American College of Rheumatology (ACR) and/or Systemic Lupus Erythematosus International Collaborating Clinics (SLICC) criteria. IgG anti-CCP, anti-CAP and anti-CarP were analysed by immunoassays. Radiographic data from 102 Swedish patients were available.

    RESULTS: There were 16 Linköping (6.8%) and 11 Leiden patients (5.4%) who were anti-CCP-positive, of whom approximately one third were citrulline-dependent: 40/441 (9.1%) were anti-CarP-positive, and 33% of the anti-CarP-positive patients were identified as anti-CCP-positive. No associations were found comparing anti-CCP or anti-CarP with ACR-defined phenotypes, immunologic abnormalities or smoking habits. Radiographically confirmed erosions were found in 10 patients, and were significantly associated with anti-CCP, anti-CarP and RF. Musculoskeletal ultrasonography scores were higher in anti-CCP-positive compared to anti-CCP-negative patients.

    CONCLUSIONS: In the hitherto largest anti-CarP study in SLE, we demonstrate that anti-CarP is more prevalent than anti-CCP and that the overlap is limited. We obtained some evidence that both autoantibodies seem to be associated with erosivity. Similar pathogenetic mechanisms to those seen in RA may be relevant in a subgroup of SLE cases with a phenotype dominated by arthritis.

    Assessment of Turbulent Flow Effects on the Vessel Wall Using Four-Dimensional Flow MRI2017In: Magnetic Resonance in Medicine, ISSN 0740-3194, E-ISSN 1522-2594, Vol. 77, no 6, p. 2310-2319Article in journal (Refereed)
    Abstract [en]

    Purpose: To explore the use of MR-estimated turbulence quantities for the assessment of turbulent flow effects on the vessel wall. Methods: Numerical velocity data for two patient-derived models was obtained using computational fluid dynamics (CFD) for two physiological flow rates. The four-dimensional (4D) Flow MRI measurements were simulated at three different spatial resolutions and used to investigate the estimation of turbulent wall shear stress (tWSS) using the intravoxel standard deviation (IVSD) of velocity and turbulent kinetic energy (TKE) estimated near the vessel wall. Results: Accurate estimation of tWSS using the IVSD is limited by the spatial resolution achievable with 4D Flow MRI. TKE, estimated near the wall, has a strong linear relationship to the tWSS (mean R(2=)0.84). Near-wall TKE estimates from MR simulations have good agreement to CFD-derived ground truth (mean R-2=0.90). Maps of near-wall TKE have strong visual correspondence to tWSS. Conclusion: Near-wall estimation of TKE permits assessment of relative maps of tWSS, but direct estimation of tWSS is challenging due to limitations in spatial resolution. Assessment of tWSS and near-wall TKE may open new avenues for analysis of different pathologies. (C) 2016 International Society for Magnetic Resonance in Medicine

    Visualizing and quantifying flow stasis in abdominal aortic aneurysms in men using 4D flow MRI2019In: Magnetic Resonance Imaging, ISSN 0730-725X, E-ISSN 1873-5894, Vol. 57, p. 103-110Article in journal (Refereed)
    Abstract [en]

    Purpose: To examine methods for visualizing and quantifying flow stasis in abdominal aortic aneurysms (AAA) using 4D Flow MRI. Methods: Three methods were investigated: conventional volumetric residence time (VRT), mean velocity analysis (MVA), and particle travel distance analysis (TDA). First, ideal 4D Flow MRI data was generated using numerical simulations and used as a platform to explore the effects of noise and background phase-offset errors, both of which are common 4D Flow MRI artifacts. Error-free results were compared to noise or offset affected results using linear regression. Subsequently, 4D Flow MRI data for thirteen (13) subjects with AAA was acquired and used to compare the stasis quantification methods against conventional flow visualization. Results: VRT (R-2 = 0.69) was more sensitive to noise than MVA (R-2 = 0.98) and TDA (R-2 = 0.99) at typical noncontrast signal-to-noise ratio levels (SNR = 20). VRT (R-2 = 0.14) was more sensitive to background phase-offsets than MVA (R-2 = 0.99) and TDA (R-2 = 0.96) when considering a 95% effective background phase-offset correction. Qualitatively, TDA outperformed MVA (Wilcoxon p amp;lt; 0.005, mean score improvement 1.6/5), and had good agreement (median score 4/5) with flow visualizations. Conclusion: Flow stasis can be quantitatively assessed using 4D Flow MRI. While conventional residence time calculations fail due to error accumulation as a result of imperfect measured velocity fields, methods that do not require lengthy particle tracking perform better. MVA and TDA are less sensitive to measurement errors, and TDA generates results most similar to those obtained using conventional flow visualization.

    Interpretation of postmortem vitreous concentrations of sodium and chloride2016In: Forensic Science International, ISSN 0379-0738, E-ISSN 1872-6283, Vol. 263, p. 107-113Article in journal (Refereed)
    Abstract [en]

    Vitreous fluid can be used to analyze sodium and chloride levels in deceased persons, but it remains unclear to what extent such results can be used to diagnose antemortem sodium or chloride imbalances. In this study we present vitreous sodium and chloride levels from more than 3000 cases. We show that vitreous sodium and chloride levels both decrease with approximately 2.2 mmol/L per day after death. Since potassium is a well-established marker for postmortem interval (PMI) and easily can be analyzed along with sodium and chloride, we have correlated sodium and chloride levels with the potassium levels and present postmortem reference ranges relative the potassium levels. We found that virtually all cases outside the reference range show signs of antemortem hypo- or hypernatremia. Vitreous sodium or chloride levels can be the only means to diagnose cases of water or salt intoxication, beer potomania or dehydration. We further show that postmortem vitreous sodium and chloride strongly correlate and in practice can be used interchangeably if analysis of one of the ions fails. It has been suggested that vitreous sodium and chloride levels can be used to diagnose drowning or to distinguish saltwater from freshwater drowning. Our results show that in cases of freshwater drowning, vitreous sodium levels are decreased, but that this mainly is an effect of postmortem diffusion between the eye and surrounding water rather than due to the drowning process, since the decrease in sodium levels correlates with immersion time.

    A new model for the estimation of time of death from vitreous potassium levels corrected for age and temperature2015In: Forensic Science International, ISSN 0379-0738, E-ISSN 1872-6283, Vol. 254, p. 158-166Article in journal (Refereed)
    Abstract [en]

    Analysis of potassium concentration in the vitreous fluid of the eye is frequently used by forensic pathologists to estimate the postmortem interval (PMI), particularly when other methods commonly used in the early phase of an investigation can no longer be applied. The postmortem rise in vitreous potassium has been recognized for several decades and is readily explained by a diffusion of potassium from surrounding cells into the vitreous fluid. However, there is no consensus regarding the mathematical equation that best describes this increase. The existing models assume a linear increase, but different slopes and starting points have been proposed. In this study, vitreous potassium levels, and a number of factors that may influence these levels, were examined in 462 cases with known postmortem intervals that ranged from 2 h to 17 days. We found that the postmortem rise in potassium followed a non-linear curve and that decedent age and ambient temperature influenced the variability by 16% and 5%, respectively. A long duration of agony and a high alcohol level at the time of death contributed less than 1% variability, and evaluation of additional possible factors revealed no detectable impact on the rise of vitreous potassium. Two equations were subsequently generated, one that represents the best fit of the potassium concentrations alone, and a second that represents potassium concentrations with correction for decedent age and/or ambient temperature. The former was associated with narrow confidence intervals in the early postmortem phase, but the intervals gradually increased with longer PMIs. For the latter equation, the confidence intervals were reduced at all PMIs. Therefore, the model that best describes the observed postmortem rise in vitreous potassium levels includes potassium concentration, decedent age, and ambient temperature. Furthermore, the precision of these equations, particularly for long PMIs, is expected to gradually improve by adjusting the constants as more reference data are added over time. A web application that facilitates this calculation process and allows for such future modifications has been developed. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

    Differences in symptoms, first medical contact and pre-hospital delay times between patients with ST- and non-ST-elevation myocardial infarction2019In: European heart journal. Acute cardiovascular care., ISSN 2048-8726, Vol. 8, no 3, p. 201-207Article in journal (Refereed)
    Abstract [en]

    AIM: In ST-elevation myocardial infarction, time to reperfusion is crucial for the prognosis. Symptom presentation in myocardial infarction influences pre-hospital delay times but studies about differences in symptoms between patients with ST-elevation myocardial infarction and non-ST-elevation myocardial infarction are sparse and inconclusive. The aim was to compare symptoms, first medical contact and pre-hospital delay times in patients with ST-elevation myocardial infarction and non-ST-elevation myocardial infarction.

    METHODS AND RESULTS: This multicentre, observational study included 694 myocardial infarction patients from five hospitals. The patients filled in a questionnaire about their pre-hospital experiences within 24 h of hospital admittance. Chest pain was the most common symptom in ST-elevation myocardial infarction and non-ST-elevation myocardial infarction (88.7 vs 87.0%, p=0.56). Patients with cold sweat (odds ratio 3.61, 95% confidence interval 2.29-5.70), jaw pain (odds ratio 2.41, 95% confidence interval 1.04-5.58), and nausea (odds ratio 1.70, 95% confidence interval 1.01-2.87) were more likely to present with ST-elevation myocardial infarction, whereas the opposite was true for symptoms that come and go (odds ratio 0.58, 95% confidence interval 0.38-0.90) or anxiety (odds ratio 0.52, 95% confidence interval 0.29-0.92). Use of emergency medical services was higher among patients admitted with ST-elevation myocardial infarction. The pre-hospital delay time from symptom onset to first medical contact was significantly longer in non-ST-elevation myocardial infarction (2:05 h vs 1:10 h, p=0.001).

    CONCLUSION: Patients with ST-elevation myocardial infarction differed from those with non-ST-elevation myocardial infarction regarding symptom presentation, ambulance utilisation and pre-hospital delay times. This knowledge is important to be aware of for all healthcare personnel and the general public especially in order to recognise symptoms suggestive of ST-elevation myocardial infarction and when to decide if there is a need for an ambulance.

    Psychoeducational support to post cardiac surgery heart failure patients and their partners: A randomised pilot study2015In: Intensive & Critical Care Nursing, ISSN 0964-3397, E-ISSN 1532-4036, Vol. 31, no 1, p. 10-18Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: Postoperative heart failure is a serious complication that changes the lives of both the person who is critically ill and family in many ways. The purpose of this study was to evaluate the effects of an intervention in postoperative heart failure patient-partner dyads regarding health, symptoms of depression and perceived control.

    RESEARCH METHODOLOGY/DESIGN: Pilot study with a randomised controlled design evaluating psychosocial support and education from an interdisciplinary team.

    SETTING: Patients with postoperative heart failure and their partners.

    MAIN OUTCOME MEASURES: SF-36, Beck Depression Inventory, Perceived Control at baseline, 3 and 12 months.

    RESULTS: A total of 42 patient-partner completed baseline assessment. Partners in the intervention group increased health in the role emotional and mental health dimensions and patients increased health in vitality, social function and mental health dimensions compared with the control group. Patients' perceived control improved significantly in the intervention group over time.

    CONCLUSION: Psychoeducational support to post cardiac surgery heart failure dyads improved health in both patients and partners at short term follow-up and improved patients' perceived control at both short and long-term follow-up. Psychoeducational support appears to be a promising intervention but the results need to be confirmed in larger studies.

    Abstract [en]

    Families who have a seriously ill family member in an intensive care unit face a demanding situation,threatening the normal functioning of the family. The burden onfamilies can be reduced by usingavailable resources, cohesiveness, supportive communication, flexibility and othersocial resources outsidethe family.If health promoting conversationsoffered to the family's ownabilities is strengthened, thisshould result in health promoting values to the family. In order to gain a better understanding of familyadaptation, we must not only see the family as a unit but also acknowledge the experiences of eachmember of the family.

    To investigate outcomes of the nurse led intervention, “Health promoting conversations with families” on family functioning and wellbeing in families with a member who has had critical illness.

    The study is a RCT study using a pre-test, post-test intervention and control group design. The inclusioncriteria will be: Patients over the age of 18, a minimum of 72 hours at the intensive care unit, and at leastone family member (>15 years) to each patient interested in participating. Within the study, quantitativeand qualitative data will be collected and analysed with descriptive and analytical statistical methods ofthe quantitative data and content analysis of the qualitative data.

    The conversations were considered to be healing and learning, because the family members can completememory loss from other family members' stories. Families showed a tendency to less stress and morehope, better mental health but poorer physical health in a pilot study. The project highlights knowledgeabout the health benefits of conversations about families where a family member has suffered from poorhealth. The health promoting conversations has a structure that makes conversations relatively easy toimplement in everyday healthcare and will be beneficial for many patients with critical illness and theirfamilies.

    The health promoting conversations intervention for families with a critically ill relative: A pilot study2019In: Intensive & Critical Care Nursing, ISSN 0964-3397, E-ISSN 1532-4036, Vol. 50, p. 103-110Article in journal (Refereed)
    Abstract [en]

    Background: After intensive care unit treatment, patients often have prolonged impairments that affect their physical, cognitive and mental health. Family members can face overwhelming and emotionally challenging situations and their concerns and needs must be addressed. Objective: We investigated the outcomes of pilot randomised control trial, a nurse-led family intervention, Health Promoting Conversations, which focused on family functioning and wellbeing in families with a critically ill member. Study design: This randomised controlled pilot study used a pre-test, post-test design with intervention and control groups to investigate the outcomes of the nurse-led intervention in 17 families. Outcome measures: The Health Promoting Conversations intervention was evaluated using validated instruments that measure family functioning and family wellbeing: the General Functioning sub-scale from the McMaster Family Assessment Device; the Family Sense of Coherence, the Herth Hope Index, and the Medical Outcome Short-Form Health Survey. Descriptive and analytical statistical methods were used to analyse the data. Results: After 12 months, the intervention group reported better family functioning than the control group. The intervention group also had better social functioning and mental health after 12 months. Conclusion: This intervention may improve family wellbeing by improving family function, reducing stress, and promoting better mental health. (C) 2018 Elsevier Ltd. All rights reserved.

    Patients' self-perceived health, coping, anxiety, depression and stress before and up to 2 years after a heart or lung transplantation.2015Conference paper (Other academic)
    Abstract [en]

    Background: Psychosocial factors are important aspects for patients before, on waiting list, and after a heart or lung transplantation.

    Aim: To illuminate patients' self-­‐perceived health, coping, anxiety, depression and stress before and up to 2 years after heart or lung transplantation.

    Method: Fifty-­‐four adult patients (28 cardiac and 26 lung) were included. They responded to questionnaires about quality of life, coping, anxiety, depression and stress when they were accepted for the transplant waiting list, then 6 months, 1 year and 2 years after a heart or lung transplantation. 

    Result: Mean waiting time was 37 weeks for cardiac patients and 29 weeks for lung patients. The patients had a lower coping ability and self-­‐perceived health at baseline and showed an improvement over time after the transplantation. Excluding pain, which increased and persisted over time after the transplantation, especially for the lung patients. Twenty-­‐three percent of all patients showed clinically anxiety before transplantation compared to 0-­‐8 % after transplantation. However, both before and after, clinical depression was significantly less frequent. Nearly half (44 %) of the patients scored medium or high level of intrusion stress and 38% of avoidance stress before the transplantation, which declined gradually over the years.

    Conclusion: Transplantation has led to positive psychosocial effects at 6 months, 1 year and 2 years after the heart or lung transplantation for most of the patients. The healthcare professionals must ensure to be aware of the challenges faced by their patients in daily living, not only the symptoms of their severe chronic disease but also psychosocial factors mainly before but even after a heart or lung transplantation. Patients have an underlying serious, chronic disease where severe long-­‐term life-­‐threatening complications suddenly can occur

    Psycho-social aspects before and up to 2 years after heart or lung transplantation - experience of patients and their next of kin.2017In: Clinical Transplantation, ISSN 0902-0063, E-ISSN 1399-0012, Vol. 31, no 3, article id e12905Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Psychosocial factors are important for patients undergoing heart (HTx) or lung (LTx) transplantation, and for their next of kin (NoK).

    AIM: To describe health-related quality of life (patients only), anxiety, depression, stress, coping ability and burden (NoK only) for patients and their NoK before and up to 2 years after HTx or LTx.

    DESIGN: Adult patients (28 heart and 26 lung) and their appointed NoK were surveyed with questionnaires about specific psychosocial topics when they were accepted for the transplantation waiting list and 6 months, 1 year, and 2 years after transplantation.

    FINDINGS: Patients' coping ability and self-perceived health were low at baseline and improved over time after the transplantation. However, lung patients took longer time to recover in terms of health-related quality of life, depression, and stress than heart patients. Similarly, NoK of lung patients experienced a higher burden and more stress 1 year after transplantation than NoK of heart patients.

    CONCLUSIONS: Healthcare professionals should be aware of the psychosocial challenges patients and their NoK face in daily living and provide support both before and after heart or lung transplantation. Especially, given that these patients have a serious, chronic, underlying disease. This article is protected by copyright. All rights reserved.

    Caregiving tasks and caregiver burden; effects of an psycho-educational intervention in partners of patients with post-operative heart failure2015In: Heart & Lung, ISSN 0147-9563, E-ISSN 1527-3288, Vol. 44, no 4, p. 270-275Article in journal (Refereed)
    Abstract [en]

    Objective: To evaluate the effects of a psycho-educational intervention on caregiver burden in partners of patients with postoperative heart failure. Background: Since partners of cardiac surgery patients play a significant role in the patients recovery, it is important to address their needs during hospitalization and after discharge. Methods: Forty-two patients with postoperative heart failure and their partners participated in a randomized controlled pilot study. Dyads in the intervention group received psycho-educational support from a multidisciplinary team. Dyads in the control group received usual care. Results: No significant differences were found in the performance of caregiving tasks and perceived caregiver burden in the control versus the intervention group. Conclusion: A pilot study exploring the effects of a psycho-educational intervention in patients and their partners did not reveal significant effects with regard to reduced feelings of burden in partners. Alleviating caregiver burden in partners may need a more intense or specific approach. (C) 2015 Elsevier Inc. All rights reserved.

    Right ventricular systolic function and mechanical dispersion identify patients with arrhythmogenic right ventricular cardiomyopathy.2018In: Clinical Physiology and Functional Imaging, ISSN 1475-0961, E-ISSN 1475-097X, Vol. 38, no 5, p. 779-787Article in journal (Refereed)
    Abstract [en]

    PURPOSE: To assess right ventricular (RV) regional and global systolic function using feature tracking (FT) in patients with a definite diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC) and to investigate if changes in strain amplitude and mechanical dispersion indicate a propensity for arrhythmia.

    MATERIALS AND METHODS: Twenty-seven patients fulfilling Task Force Criteria for ARVC and 24 healthy volunteers underwent MR at 1·5 Tesla. Steady-state free precession cine of long-axis slices and a short-axis stack of the RV was acquired. Segmental longitudinal systolic strain amplitude and time-to-peak (TTP) strain were measured in the four- and two-chamber views of the RV.

    RESULTS: Compared to controls, patients with ARVC had lower RV ejection fraction (RVEF), (53% vs 57%, P = 0·012) and lower longitudinal strain amplitude in the RV free wall (-20·6 vs -26·3%, P = 0·014) and in the basal part of the RV (-22·8 vs -31·7%, P<0·001). Mechanical dispersion, defined as the standard deviation (SD) of TTP of RV segments, was larger in patients with ARVC (48 ms [21-74] vs 35 ms [13-66 ms], P = 0·02). Patients with ventricular tachycardia (VT) or non-sustained VT had lower RVEF (46% vs 55%, P = 0·008), but did not have significantly lower RV strain amplitude (-19·5% vs 21·0%, P = 0·073) and no signs of mechanical dispersion (49 ms vs 48 ms, P = 0·861) compared to patients without arrhythmia.

    CONCLUSION: ARVC patients had lower longitudinal absolute strain amplitude in basal RV segments and increased mechanical dispersion compared to healthy volunteers, but the presence of mechanical dispersion was not predictive of ventricular arrhythmia.

    Adjustment, avoidance, interaction, and acceptance strategies where used by men with participation restrictions due to early RA2015Conference paper (Refereed)
    Abstract [en]

    Background: Approximately 1/3 of patients diagnosed with the chronic disease Rheumatoid Arthritis (RA) are men, however few studies describe experiences and strategies to handle daily activities [2]. Daily life with a chronic disease means learning to live under new circumstances. This also foresee a continuous adaptation to new ways of living. The process of coping in which the individual change the perceived cause of stress as in problem-focused coping or when managing the emotions of stress, as in emotion-focused coping where first mentioned by Lazarus and Folkman [1]. Coping is described as an individual style to handle stressful events that might be changed over time.

    Objectives: The aim was to explore men's strategies for dealing with participation restrictions in everyday life due to early RA.

    Methods: This study is associated with the prospective multi-centre early arthritis project under the Swedish acronym “TIRA-2” [3]. Participants were 25 males of which 22 were work active, mean age 53 years, contemporary treated with mean disease duration of 3 years. Individual interviews were done using the Critical Incident Technique (CIT) [4]. The verbatim transcribed text were analyzed and categorized using content analysis. The study has been approved by the Ethics Committee.

    Results: The men experienced that RA partly required a changed life style and most of them used a combination of strategies to deal with the participation restrictions in relation to RA. In the adjustment strategy new behaviors and tools were used to solve participation restrictions. The avoidance strategy included deliberate avoidance of possible participation restrictions, such as staying at home in the evenings and avoiding socializing with friends. The interaction strategy included to verbally express needs and give demands in relation to others both at work and in the family and ask for help when needed. The acceptance strategy was identified by the wordings used when talking about the experienced participation restrictions as “I accept that everything takes longer time”.

    Conclusions: The interviewed men with early RA were contemporary treated and active in the work force, still, all of them had to deal with some participation restrictions. Moreover, this study claims that most men used a combination of strategies to deal with the experienced participation restriction.

    Womens situation-specific strategies in managing participation restrictions due to early rheumatoid arthritis: A gender comparison2018In: Musculoskeletal Care, ISSN 1478-2189, E-ISSN 1557-0681, Vol. 16, no 2, p. 251-259Article in journal (Refereed)
    Abstract [en]

    Introduction

    The present study explored how women describe their use of situation‐specific strategies when managing rheumatoid arthritis (RA). The aim was also to compare women's strategies with those of men, and see the extent to which they used the same strategies.

    Methods

    The data were collected using semi‐structured interviews based on the critical incident technique. The sample consisted of women with early rheumatic arthritis (n = 34), and the results were compared with data reported in a previous study on men (n = 25) from the same cohort. The patient‐described participation restrictions due to RA were firstly linked to the domains of the International Classification of Functioning, Disability and Health (ICF). The different strategies used were then categorized. The study was approved by the Research Ethics Committee of the Faculty of Health Sciences, Linköping University, Sweden.

    Results

    The study found that women used four situation‐specific strategies: adjustment, avoidance, interaction and acceptance. The same strategies had been found previously in interviews with men with RA. Women and men used these strategies to a similar extent in the ICF domains of mobility; major life arenas; domestic life; interpersonal interactions and relationships; and community, social and civic life. However, some differences were found, relating to the reported activities in self‐care and domestic life, in which women reported using strategies to a greater extent than men.

    Conclusions

    Women and men used four types of situation‐specific strategies in managing RA; adjustment, avoidance, interaction and acceptance. These situation‐specific strategies provide useful knowledge, in terms of multidisciplinary rehabilitation and for patients' significant others.

    Lived Experiences of Sex Life Difficulties in Men and Women with Early RA - The Swedish TIRA Project.2015In: Musculoskeletal Care, ISSN 1478-2189, E-ISSN 1557-0681, Vol. 13, no 4, p. 248-257Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Men and women with rheumatoid arthritis (RA) experience restrictions in everyday life, in spite of the development of new medications. Recent research has described in detail how participation limitations are experienced in everyday life from a patient perspective. However, knowledge of how sex and intimate relationships are affected is still scarce.

    OBJECTIVES: The aim of the present study was to explore sex life experiences in relation to sexual function and sexual relationships in men and women with early RA.

    METHODS: The study formed part of TIRA-2 (the Swedish acronym for the prospective multicentre early arthritis project). The data collection included 45 interviews with 21 men and 24 women, aged 20-63, which were recorded and transcribed verbatim. The critical incident technique was used to collect data, and content analysis to categorize the results.

    RESULTS: Half the participants stated that RA affected their sex life. The general descriptions formed five categories: sex life and tiredness; sex life and ageing; emotional consequences of impaired sexual function; facilitators of sexual function and sexual relationships; and strain on the sexual relationship.

    CONCLUSIONS: Sex life is affected in early RA, in spite of new effective treatment strategies. New strategies of communication, assessment and self-managing interventions concerning the sex lives of patients with RA need to be implemented by a multidisciplinary healthcare team.
