    Association of soluble tumor necrosis factor receptors 1 and 2 with nephropathy, cardiovascular events, and total mortality in type 2 diabetes2016In: Cardiovascular Diabetology, ISSN 1475-2840, E-ISSN 1475-2840, Vol. 15, no 1, p. 40-Article in journal (Refereed)
    Abstract [en]

    Aims/hypothesis: Soluble tumor necrosis factor receptors 1 and 2 (sTNFR1 and sTNFR2) contribute to experimental diabetic kidney disease, a condition with substantially increased cardiovascular risk when present in patients. Therefore, we aimed to explore the levels of sTNFRs, and their association with prevalent kidney disease, incident cardiovascular disease, and risk of mortality independently of baseline kidney function and microalbuminuria in a cohort of patients with type 2 diabetes. In pre-defined secondary analyses we also investigated whether the sTNFRs predict adverse outcome in the absence of diabetic kidney disease. Methods: The CARDIPP study, a cohort study of 607 diabetes patients [mean age 61 years, 44 % women, 45 cardiovascular events (fatal/non-fatal myocardial infarction or stroke) and 44 deaths during follow-up (mean 7.6 years)] was used. Results: Higher sTNFR1 and sTNFR2 were associated with higher odds of prevalent kidney disease [odd ratio (OR) per standard deviation (SD) increase 1.60, 95 % confidence interval (CI) 1.32-1.93, p < 0.001 and OR 1.54, 95 % CI 1.21-1.97, p = 0.001, respectively]. In Cox regression models adjusting for age, sex, glomerular filtration rate and urinary albumin/creatinine ratio, higher sTNFR1 and sTNFR2 predicted incident cardiovascular events [hazard ratio (HR) per SD increase, 1.66, 95 % CI 1.29-2.174, p < 0.001 and HR 1.47, 95 % CI 1.13-1.91, p = 0.004, respectively]. Results were similar in separate models with adjustments for inflammatory markers, HbA1c, or established cardiovascular risk factors, or when participants with diabetic kidney disease at baseline were excluded (p < 0.01 for all). Both sTNFRs were associated with mortality. Conclusions/Interpretations: Higher circulating sTNFR1 and sTNFR2 are associated with diabetic kidney disease, and predicts incident cardiovascular disease and mortality independently of microalbuminuria and kidney function, even in those without kidney disease. Our findings support the clinical utility of sTNFRs as prognostic markers in type 2 diabetes.

    Risk factors in type 2 diabetes with emphasis on blood pressure, physical activity and serum vitamin D2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background

    Type 2 diabetes is a common chronic disease with a two-fold increased risk for cardiovascular morbidity and mortality and has an increasing prevalence worldwide. This thesis is based on a study conducted in primary health care in Östergötland and Jönköping, Sweden. The aim of the thesis was to evaluate new risk markers to identify patients with high risk of developing cardiovascular disease in middle-aged men and women with type 2 diabetes.

    Methods

    Data from the cohort study CArdiovascular Risk in type 2 DIabetes – a Prospective study in Primary care (CARDIPP) was used. In paper III data were also used from CARDIPP-Revisited where all participants in the CARDIPP study were invited four years after the baseline investigation for a re-investigation. In paper IV data were used from CAREFUL which is a control group of 185 subjects without diabetes. The investigation included a standard medical history including data on diabetes duration and on-going medication. Anthropometric data were recorded and both office and ambulatory blood pressure were measured. The patients filled out a detailed questionnaire and physical activity was measured by using waist-mounted pedometers. Pedometer-determined physical activity was classified in four groups: Group 1: <5000 steps/day (‘sedentary’); Group 2: 5000-7499 steps/day (‘low active’); Group 3: 7500-9999 steps/day (‘somewhat active’); Group 4: and ≥10 000 steps/day (‘active’). Blood samples were drawn for routine analyses and also frozen for later analyses. The investigations at the departments of physiology included echocardiography, measurements of the carotid intima-media thickness, applanation tonometry and measurements of  sagittal abdominal diameter.

    Results

    Paper 1:

    Patients with a non-dipping systolic blood pressure pattern showed higher left ventricular mass index and pulse wave velocity (PWV) compared with patients with ≥10% decline in nocturnal systolic blood pressure. Patients with <10% decline in nocturnal systolic blood pressure had higher BMI and sagittal abdominal diameter, lower GFR and higher albumin:creatinine ratio and also higher levels of NT-proBNP than patients with a dipping pattern of the nocturnal blood pressure.

    Paper 2:

    The number of steps/day were inversely significantly associated with BMI, waist circumference and sagittal abdominal diameter, levels of CRP, levels of interleukin-6 and PWV.

    Paper 3:

    At the 4-year follow-up the change in PWV (ΔPWV) from baseline was calculated. The group with the lowest steps/day had a significantly higher increase in ΔPWV compared with the group with the highest steps/day. The associations between baseline steps/day and ΔPWV remained after further adjustment in a multivariate linear regression statistically significant (p=0.005). 23% of the variation in the study could be explained by our model. Every 1000 extra steps at baseline reduced the change in ΔPWV by 0.103 m/s between baseline and follow-up.

    Paper 4:

    Low vitamin D levels were associated with significantly increased risk for premature mortality in men with type 2 diabetes. High levels of parathyroid hormone were associated with significantly increased risk for premature mortality in women with type 2 diabetes. These relationships were still statistically significant also when two other well-established risk markers for mortality, PWV and carotid intima-media thickness, were added to the analyses.

    Conclusions

    Ambulatory blood pressure recording can by addressing the issue of diurnal blood pressure variation, explore early cardiovascular organ damage and microvascular complications that goes beyond effects of standardised office blood pressure measurements. Pedometer-determined physical activity may serve as a surrogate marker for inflammation and subclinical organ damage in patients with type 2 diabetes. There is novel support for the durable vascular protective role of a high level of daily physical activity, which is independent of BMI and systolic blood pressure. The use of pedometers is feasible in clinical practice and provides objective information not only about physical activity but also the future risk for subclinical organ damage in middle-aged people with type 2 diabetes. Our results indicate that low vitamin D levels in men or high parathyroid hormone levels in women give independent prognostic information of an increased risk for total mortality.

    Abstract [en]

    Aims

    To explore the association between nocturnal blood pressure (BP) dipper status and macro- and microvascular organ damage in type 2 diabetes.

    Methods

    Cross-sectional data from 663 patients with type 2 diabetes, aged 55–66 years, were analysed. Nurses measured office BP and ambulatory BP during 24 h. Individuals with ≥10% difference in nocturnal systolic blood pressure (SBP) relative to daytime values were defined as dippers. Non-dippers were defined as <10% nocturnal decrease in SBP. Estimated glomerular filtration rate (GFR) was calculated and microalbuminuria was measured by albumin:creatinine ratio (ACR). Aortic pulse wave velocity (PWV) was measured with applanation tonometry over the carotid and femoral arteries.

    Results

    We identified 433 dippers and 230 subjects with a nocturnal non-dipping pattern. Nocturnal SBP dipping was independently of office SBP associated with decreased PWV (p = 0.008), lower ACR (p = 0.001) and NT-proBNP (p = 0.001) and increased GFR (p < 0.001).

    Conclusions

    We conclude that diurnal BP variation provides further information about early macro- and microvascular subclinical organ damage that goes beyond standardized office BP measurements in patients with type 2 diabetes.

    Diabet. Med. 29, 11191125 (2012) Abstract Aims The aim of this study was to explore the association between pedometer-determined physical activity versus measures of obesity, inflammatory markers and arterial stiffness in people with Type 2 diabetes. Methods We analysed data from 224 men and 103 women with Type 2 diabetes, aged 5466 years. Physical activity was measured with waist-mounted pedometers during three consecutive days and the number of steps/day were calculated and classified in four groups: andlt; 5000 steps/day, 50007499 steps/day, 75009999 steps/day and andgt;= 10000 steps/day. Blood samples were analysed for lipids, HbA1c, inflammatory markers including C-reactive protein and interleukin-6. Nurses measured blood pressure and anthropometrics. Aortic pulse wave velocity was measured with applanation tonometry over the carotid and femoral arteries. Results Mean steps/day was 7683 +/- 3883 (median 7222, interquartile range 486910 343). There were no differences in age, diabetes duration, blood pressure, lipids or glycaemic control between the four groups of pedometer-determined physical activity. Subjects with higher steps/day had lower BMI (28.8 vs. 31.5 kg/m2, P andlt; 0.001), waist circumference (101.7 vs. 108.0 cm, P andlt; 0.001), lower levels of C-reactive protein (1.6 vs. 2.6 mg/l, P = 0.007), lower levels of interleukin-6 (1.9 vs. 3.8 pg ml, P andlt; 0.001) and lower pulse wave velocity (10.2 vs. 11.0 m/s, P = 0.009) compared with less physically active people. Conclusions We conclude that physical activity measured with pedometer was associated not only with less abdominal obesity, but also with decreased systemic low-grade inflammation as well as with low arterial stiffness, in people with Type 2 diabetes.

    Abstract [en]

    Aim To explore prospectively the correlation between the level of pedometer-determined physical activity at the start of the study and the change in pulse wave velocity from baseline to 4 years later in people with Type 2 diabetes.

    Methods We analysed data from 135 men and 53 women with Type 2 diabetes, aged 54–66 years. Physical activity was measured with waist-mounted pedometers on 3 consecutive days and the numbers of steps/day at baseline were classified into four groups: <5000 steps/day, 5000–7499 steps/day, 7500–9999 steps/day and ≥10 000 steps/day. Pulse wave velocity was measured using applanation tonometry over the carotid and femoral arteries at baseline and after 4 years.

    Results The mean (±sd; range) number of steps/day was 8022 (±3765; 956–20 921). The participants with the lowest level of physical activity had a more pronounced increase in the change in pulse wave velocity compared with the participants with the highest. When change in pulse wave velocity was analysed as a continuous variable and adjusted for sex, age, diabetes duration, HbA1c, BMI, systolic blood pressure, pulse wave velocity at baseline, β-blocker use, statin use, unemployment, smoking and diabetes medication, the number of steps/day at baseline was significantly associated with a less steep increase in change in pulse wave velocity (P=0.005). Every 1000 extra steps at baseline corresponded to a lower increase in change in pulse wave velocity of 0.103 m/s.

    Conclusions We found that a high level of pedometer-determined physical activity was associated with a slower progression of arterial stiffness over 4 years in middle-aged people with Type 2 diabetes.

    Abstract [en]

    Background: Low levels of vitamin D have been related to increased mortality and morbidity in several non-diabetic studies. We aimed to prospectively study relationships between serum 25-OH vitamin D-3 (vitamin D) and of serum parathyroid hormone (PTH) to total mortality in type 2 diabetes. We also aimed to compare the levels of these potential risk-factors in patients with and without diabetes. Methods: The main study design was prospective and observational. We used baseline data from 472 men and 245 women who participated in the "Cardiovascular Risk factors in Patients with Diabetes-a Prospective study in Primary care" study. Patients were 55-66 years old at recruitment, and an age-matched non-diabetic sample of 129 individuals constituted controls for the baseline data. Carotid-femoral pulse-wave velocity (PWV) was measured with applanation-tonometry and carotid intima-media thickness (IMT) with ultrasound. Patients with diabetes were followed for all-cause mortality using the national Swedish Cause of Death Registry. Results: Levels of vitamin D were lower in patients with diabetes than in controls, also after correction for age and obesity, while PTH levels did not differ. Nine women and 24 men died during 6 years of median follow up of the final cohort (n = 698). Vitamin D levels were negatively related to all-cause mortality in men independently of age, PTH, HbA1c, waist circumference, 24-h systolic ambulatory-blood pressure (ABP) and serum-apoB (p = 0.049). This finding was also statistically significant when PWV and IMT were added to the analyses (p = 0.028) and was not affected statistically when medications were also included in the regression-analysis (p = 0.01). In the women with type 2 diabetes, levels of PTH were positively related with all-cause mortality in the corresponding calculations (p = 0.016 without PWV and IMT, p = 0.006 with PWV and IMT, p = 0.045 when also adding medications to the analysis), while levels of vitamin D was without statistical significance (p greater than 0.9). Conclusions: Serum vitamin D in men and serum PTH in women give prognostic information in terms of total-mortality that are independent of regular risk factors in addition to levels of ABP, IMT and PWV.

    Conclusions

    We conclude that diurnal BP variation provides further information about early macro- and microvascular subclinical organ damage that goes beyond standardized office BP measurements in patients with type 2 diabetes.

    A prospective observational study of all-cause mortality in relation to serum 25-OH vitamin D-3 and parathyroid hormone levels in patients with type 2 diabetes2015In: Diabetology and Metabolic Syndrome, ISSN 1758-5996, E-ISSN 1758-5996, Vol. 7, no 53Article in journal (Refereed)

In the women with type 2 diabetes, levels of PTH were positively related with all-cause mortality in the corresponding calculations (p = 0.016 without PWV and IMT, p = 0.006 with PWV and IMT, p = 0.045 when also adding medications to the analysis), while levels of vitamin D was without statistical significance (p greater than 0.9). Conclusions: Serum vitamin D in men and serum PTH in women give prognostic information in terms of total-mortality that are independent of regular risk factors in addition to levels of ABP, IMT and PWV.

    Pedometer-determined physical activity is linked to low systemic inflammation and low arterial stiffness in Type 2 diabetes2012In: Diabetic Medicine, ISSN 0742-3071, E-ISSN 1464-5491, Vol. 29, no 9, p. 1119-1125Article in journal (Refereed)

    Diabet. Med. 29, 11191125 (2012) Abstract Aims The aim of this study was to explore the association between pedometer-determined physical activity versus measures of obesity, inflammatory markers and arterial stiffness in people with Type 2 diabetes. Methods We analysed data from 224 men and 103 women with Type 2 diabetes, aged 5466 years. Physical activity was measured with waist-mounted pedometers during three consecutive days and the number of steps/day were calculated and classified in four groups: andlt; 5000 steps/day, 50007499 steps/day, 75009999 steps/day and andgt;= 10000 steps/day. Blood samples were analysed for lipids, HbA1c, inflammatory markers including C-reactive protein and interleukin-6. Nurses measured blood pressure and anthropometrics. Aortic pulse wave velocity was measured with applanation tonometry over the carotid and femoral arteries. Results Mean steps/day was 7683 +/- 3883 (median 7222, interquartile range 486910 343). There were no differences in age, diabetes duration, blood pressure, lipids or glycaemic control between the four groups of pedometer-determined physical activity. Subjects with higher steps/day had lower BMI (28.8 vs. 31.5 kg/m2, P andlt; 0.001), waist circumference (101.7 vs. 108.0 cm, P andlt; 0.001), lower levels of C-reactive protein (1.6 vs. 2.6 mg/l, P = 0.007), lower levels of interleukin-6 (1.9 vs. 3.8 pg ml, P andlt; 0.001) and lower pulse wave velocity (10.2 vs. 11.0 m/s, P = 0.009) compared with less physically active people. Conclusions We conclude that physical activity measured with pedometer was associated not only with less abdominal obesity, but also with decreased systemic low-grade inflammation as well as with low arterial stiffness, in people with Type 2 diabetes.

    Pedometer-determined physical activity level and change in arterial stiffness in Type 2 diabetes over 4 years2016In: Diabetic Medicine, ISSN 0742-3071, E-ISSN 1464-5491, Vol. 33, no 7, p. 992-997Article in journal (Refereed)
    Abstract [en]

    Aim To explore prospectively the correlation between the level of pedometer-determined physical activity at the start of the study and the change in pulse wave velocity from baseline to 4 years later in people with Type 2 diabetes.

    Methods We analysed data from 135 men and 53 women with Type 2 diabetes, aged 54–66 years. Physical activity was measured with waist-mounted pedometers on 3 consecutive days and the numbers of steps/day at baseline were classified into four groups: <5000 steps/day, 5000–7499 steps/day, 7500–9999 steps/day and ≥10 000 steps/day. Pulse wave velocity was measured using applanation tonometry over the carotid and femoral arteries at baseline and after 4 years.

    Results The mean (±sd; range) number of steps/day was 8022 (±3765; 956–20 921). The participants with the lowest level of physical activity had a more pronounced increase in the change in pulse wave velocity compared with the participants with the highest. When change in pulse wave velocity was analysed as a continuous variable and adjusted for sex, age, diabetes duration, HbA1c, BMI, systolic blood pressure, pulse wave velocity at baseline, β-blocker use, statin use, unemployment, smoking and diabetes medication, the number of steps/day at baseline was significantly associated with a less steep increase in change in pulse wave velocity (P=0.005). Every 1000 extra steps at baseline corresponded to a lower increase in change in pulse wave velocity of 0.103 m/s.

    Conclusions We found that a high level of pedometer-determined physical activity was associated with a slower progression of arterial stiffness over 4 years in middle-aged people with Type 2 diabetes.
