    Influence of low high-density lipoprotein cholesterol and elevated triglyceride on coronary heart disease events and response to simvastatin therapy in 4S2001In: Circulation, ISSN 0009-7322, E-ISSN 1524-4539, Vol. 104, no 25, p. 3046-3051Article in journal (Refereed)
    Abstract [en]

    Background - Patients with low HDL cholesterol (HDL-C) and elevated triglyceride had an increased risk for coronary heart disease (CHD) events and received the greatest benefit with fibrate therapy in substudy analyses of the Helsinki Heart Study and the Bezafibrate Infarction Prevention Study. Methods and Results - In this post hoc analysis of the Scandinavian Simvastatin Survival Study, which enrolled patients with elevated LDL cholesterol (LDL-C) and CHD, subgroups defined by HDL-C and triglyceride quartiles were compared to examine the influence of HDL-C and triglyceride on CHD events and response to therapy. Patients in the lowest HDL-C (<1.00 mmol/L [39 mg/dL]) and highest triglyceride (>1.80 mmol/L [159 mg/dL]) quartiles (lipid triad, n=458) had increased proportions of other features of the metabolic syndrome (increased body mass index, hypertension, diabetes), men, prior myocardial infarction, prior revascularization, and ▀-blocker use than patients in the highest HDL-C (>1.34 mmol/L [52 mg/dL]) and lowest triglyceride (<1.11 mmol/L [98 mg/dL]) quartiles (isolated LDL-C elevation, n=545). The major coronary event rate was highest in lipid triad patients on placebo (35.9%), and this subgroup had the greatest event reduction (relative risk 0.48, 95% CI 0.33 to 0.69), a significant treatment-by-subgroup interaction (P=0.03) indicated a greater treatment effect in the lipid triad subgroup than the isolated LDL-C elevation subgroup. Conclusions - Patients with elevated LDL-C, low HDL-C, and elevated triglycerides were more likely than patients with isolated LDL-C elevation to have other characteristics of the metabolic syndrome, had increased risk for CHD events on placebo, and received greater benefit with simvastatin therapy.

    The renin-angiotensin-aldosterone system is suppressed in adults with Type 1 diabetes2000In: jraas. Journal of the renin-angiotensin-aldosterone system, ISSN 1470-3203, E-ISSN 1752-8976, Vol. 1, no 4, p. 353-356Article in journal (Refereed)
    Abstract [en]

    Poor glycaemic control and high blood pressure are two important risk factors for the development of retinopathy and nephropathy in Type 1 diabetes. The renin-angiotensin-aldosterone system (RAAS) may be involved in this process, since treatment with angiotensin-converting enzyme (ACE) inhibitors postpones the development of these complications. We investigated whether plasma renin activity (PRA), plasma angiotensin II (Ang II) and atrial natriuretic peptide (ANP) differed in Type 1 diabetic patients compared with healthy controls. We recruited 80 patients with Type 1 diabetes of more than 10 years' duration and 75 age-matched controls. We found that PRA and Ang II concentrations were significantly lower in patients than in the controls. The levels of ANP, on the other hand, were higher in patients than in controls. PRA correlated negatively to the mean value of HbA1c during the previous five years. PRA and Ang II were significantly lower in patients with mean HbA1c. >8.4% compared with those with mean HbA1c 7.2%. In summary, we found patients with Type 1 diabetes to have RAAS suppression and increased ANP levels, suggesting a state of fluid retention.

    Inhibitory effect of diabetes on proliferation of vascular smooth muscle after balloon injury in rat aorta2000In: Experimental Diabetes Research, ISSN 1687-5214, E-ISSN 1687-5303, Vol. 1, no 2, p. 101-109Article in journal (Refereed)
    Abstract [en]

    The effect of streptozotocin-induced diabetes on cell proliferation in rat aortic intima-media, as well as on local gene expression of transforming growth factor-β1 (TGF-β1) was studied. TGF-β1 mRNA was measured by solution hybridization and TGF-β1 protein by ELISA. Proliferation was measured by bromodeoxyuridine incorporation into DNA two days after balloon injury. All BrdU-labelled cells observed were smooth muscle cells. After a diabetes duration of 2 and 4 weeks, labelled cells were significantly fewer compared with controls. Circulating levels of total TGF-β1 were lowered in rats with 2 weeks diabetes. Although the balloon injury procedure by itself stimulated the gene expression of TGF-β1, no significant difference in TGF-β1 mRNA content between diabetic and control rats after injury was found. In conclusion: vascular smooth muscle proliferation in vivo is inhibited by the diabetic state in this model of insulin deficient diabetes and this inhibition is not related to an impaired local expression of TGF-β1.

    Daytime ambulatory blood pressure correlates strongly with the echocardiographic diameter of aortic coarctation2001In: Scandinavian Cardiovascular Journal, ISSN 1401-7431, E-ISSN 1651-2006, Vol. 35, no 5, p. 335-339Article in journal (Refereed)
    Abstract [en]

    Objective.-To relate the echocardiographic aortic arch-diameter to ambulatory and clinic blood pressure (BP) in patients with aortic coarctation. Design.-Eighteen adult patients (50% men) were recruited from the coarctation registry of the Linkoping Heart Centre. Biplane-trans-oesophageal echocardiography (TEE) was performed with Acuson XP 128/10, ambulatory BP was recorded with Spacelab models 90202/90205. Results.-Systolic clinic and ambulatory BP levels were higher in patients than in the 36 controls (clinic BP: 146 ▒ 25 mmHg vs 119 ▒ 10 mmHg, p = 0.0009, ambulatory BP: 140 ▒ 18 mmHg vs 124 ▒ 11 mmHg, p = 0.009). The differences in diastolic BP levels were less obvious (clinic BP: 87 ▒ 16 mmHg vs 76 ▒ 8 mmHg, p = 0.02, ambulatory BP: 84 ▒ 13 mmHg vs 77 ▒ 9 mmHg, p = 0.052). Daytime ambulatory BP was more strongly related than clinic BP to the coarctation diameter (AD) (systolic BP r = -0.73, p = 0.0006 and r = -0.61, p = 0.007, respectively). In surgically corrected patients (n = 14) only the correlations between ambulatory systolic daytime (r = -0.61, p = 0.02) and night-time (r = -0.58, p = 0.03) BP to AD was statistically significant. Conclusion.-Ambulatory BP correlates strongly with aortic coarctation measured by TEE and would thus be the preferred technique for evaluating BP in this patient category.

    Efficacy and safety of a new long-acting drug combination, trandolapril/verapamil as compared to monotherapy in primary hypertension2000In: Blood Pressure, ISSN 0803-7051, E-ISSN 1651-1999, Vol. 9, no 2-3, p. 140-145Article in journal (Refereed)
    Abstract [en]

    Objective: To evaluate the clinical efficacy and safety of a new antihypertensive drug combination of trandolapril/verapamil compared to monotherapy with verapamil or trandolapril, in patients with mild to moderate primary hypertension. Design: A multicentre, prospective, randomized, double- blind, controlled cross-over study with specific statistical considerations. Settings: Eighteen primary health care centres and out-patient hospital clinics in Sweden. Patients: Two hundred and twenty-six outpatients with uncomplicated primary hypertension with a baseline sitting diastolic blood pressure (BP) between 95 and 115 mmHg. Interventions: After a 4-week placebo period, patients were randomized to treatment for 8 weeks with trandolapril/verapamil (2 mg/180 mg) or each drug alone (verapamil 240 mg, trandolapril 2 mg) for 8 weeks. Main outcome measures: Treatment responses (blood pressure (BP) fall and rate pressure product) to the three regimens with statistical comparison and also in relation to plasma concentrations of active renin (AR). Adverse events and safety were also evaluated. Results: The mean BP fall was significantly greater with the combination (20/15 mmHg), p < 0.00054, as compared to both trandolapril (14/11 mmHg) or verapamil (13/11) mmHg. The difference between verapamil and trandolapril was not significant. Rate pressure product decreased significantly more on the combination, p < 0.001, than on trandolapril or verapamil alone. Treatment response to trandolapril was positively correlated to initial AR (r = 0.30- 0.43). All treatments were well tolerated and safe. Conclusions: The new fixed drug combination trandolapril/verapamil was superior to monotherapy with either of these drugs alone regarding reduction of both BP and rate pressure product. This combination can be safely and effectively used for the treatment of mild to moderate primary hypertension.

    Ultrasound determined carotid and femoral atherosclerosis in Lithuanian and Swedish men: The LiVicordia study2000In: Atherosclerosis, ISSN 0021-9150, E-ISSN 1879-1484, Vol. 151, no 2, p. 501-508Article in journal (Refereed)
    Abstract [en]

    Coronary heart disease mortality is four times higher in Lithuanian compared to Swedish middle-aged men. Using the same equipment (Acuson XP10 with 5 MHz linear transducer) and staff, we compared the amount of atherosclerosis in carotid and femoral arteries in 100 randomly sampled 50-year-old men in each of the cities Vilnius, Lithuania and Linköping, Sweden. Atherosclerotic plaques were more abundant in Vilnius men compared to Linköping men (53 versus 28% in the common carotid artery, 73 versus 37% in the common femoral artery, P<0.001 for both). Plaques were thicker and more extended in arteries of Vilnius men, and an ultrasound atherosclerosis score was higher in both carotid and femoral arteries (P<0.001 for all). More Vilnius men had a maximal intima-media thickness of the common femoral artery above 1 mm (P<0.005). Stiffness in the common carotid artery was higher in Vilnius men (P<0.001). In a linear regression model of the pooled material, after adjustment for city was made, smoking, systolic blood pressure, low density lipoprotein cholesterol and β-carotene (inversely) significantly contributed to a high total ultrasound score (r2=0.32). These findings show that the higher coronary mortality noted in Lithuanian men goes together with a higher prevalence of early peripheral atherosclerosis.

    The use of human ultralente is limited by great intraindividual variability in overnight plasma insulin profiles2000In: Scandinavian Journal of Clinical and Laboratory Investigation, ISSN 0036-5513, E-ISSN 1502-7686, Vol. 60, no 5, p. 341-348Article in journal (Refereed)
    Abstract [en]

    Our objective was to investigate the usefulness of human ultralente insulin as basal substitution overnight in patients with Type 1 diabetes treated with multiple insulin injection therapy by evaluating the free insulin and glucose profiles, the day-to-day variability and the impact of the time of injection. Methods: Ten patients with Type 1 diabetes and with good metabolic control (mean HbAlc 6.0%), treated with regular human insulin before breakfast, lunch and dinner and human ultralente (Ultratard«) before dinner or at bedtime, were studied. Plasma profiles of blood glucose and free insulin were measured on three occasions from 16.00 h until noon the next day. On two of these occasions Ultratard« was injected before dinner and once it was injected at bedtime in randomized order. Results: Injection of regular insulin before dinner resulted in a high insulin peak during the evening but no insulin peak was found that could be attributed to ultralente. The plasma concentration of free insulin at 03.00 h was 11.0▒1.9 mU/L and it slowly decreased to 6.4▒1.4 at 12.00 h after administration of ultralente at 17.00 h. There were no differences in the mean plasma insulin profiles compared to the other occasion when insulin was given at 17.00 h or at 22.00 h. On the other hand, the intra-individual day-to-day variability of mean insulin concentration during the night was considerable, often exceeding 50%. No differences were noted in the mean blood glucose profiles between the three occasions. Conclusion: Human ultralente insulin gives an insulin profile suitable for overnight substitution, but the great day-to-day variability limits its usefulness. It can be injected before dinner or at bedtime without any change in the insulin profile during the night.

    Family characteristics and life events before the onset of autoimmune type 1 diabetes in young adults: A nationwide study2001In: Diabetes Care, ISSN 0149-5992, E-ISSN 1935-5548, Vol. 24, no 6, p. 1033-1037Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE - To elucidate whether family characteristics and stressful life events were associated with onset of autoimmune type 1 diabetes in young adults. RESEARCH DESIGN AND METHODS - This investigation was based on a nationwide study (Diabetes Incidence Study in Sweden) of newly diagnosed patients aged 15-34 years. Patients clinically classified as type 1 diabetic with antibodies to islet cells and/or to GAD65 were compared with age- and sex-matched control subjects via questionnaire. The questionnaire covered diabetes heredity, social environment, educational level, and life events experienced during the 12 months before diagnosis. RESULTS - The rate of response was 82% for the diabetic patients and 65% for the control subjects. Questionnaires from 349 diabetic patients and 979 control subjects were considered. Diabetes in relatives was more frequent in the patients (odds ratio [OR] 2.6) who were born in Sweden and whose mothers were of Swedish origin. No major stress factors were detected in the diabetic patients, however, in comparison with the control subjects, the diabetic patients had experienced fewer conflicts with their parents and had less often broken contacts with friends. CONCLUSIONS - Young adults with recent-onset type 1 diabetes were more exposed to heredity for diabetes, but no major prediabetic stress factors were detected. Our study does not directly support the concept that psychosocial stressful life events are involved in the development of autoimmune type 1 diabetes in young adults.

    Less difference between office and ambulatory blood pressure in women than in men both before and during antihypertensive treatment2000In: Blood Pressure, ISSN 0803-7051, E-ISSN 1651-1999, Vol. 9, no 6, p. 340-345Article in journal (Refereed)
    Abstract [en]

    In 199 subjects (56% women) with a diastolic blood pressure (BP) of 95-115 mmHg, 5 mg of either amlodipine or felodipine extended release (ER) was given for 4 weeks following 4 weeks of placebo-treatment. BP was measured by conventional clinic BP technique and by 24-h ambulatory BP monitoring (Spacelab 90202/90207). Men and women had identical clinic BP at baseline and it was lowered equally much by 4 weeks of treatment (men: 158/101 and 147/93, women: 159/102 and 149/93 mmHg, respectively). However, ambulatory BP was higher in women than in men both before and after treatment (men: 145/91 and 134/85, women: 149/95 and 140/89 mmHg, respectively, p < 0.05 for both comparisons). The difference between clinic BP and daytime ambulatory BP was higher in men than in women (systolic men: 8.1 +/- 14, women: 3.7 +/- 15 mmHg, respectively, p = 0.04, diastolic men: 5.5 +/- 8.0, women: 2.1 +/- 8.3 mmHg, p = 0.004). The correlation between the treatment effect measured by ambulatory and clinic BP was poor (systolic r = 0.26, p < 0.0001, diastolic r = 0.17, p = 0.03) and was unaffected by exclusion of subjects with normal ambulatory BP. The poor correlation between treatment effects measured as clinic and ambulatory BP is intriguing, and suggests that using ambulatory BP instead of clinic BP for monitoring the treatment of hypertension could affect the clinical outcome.

    Statin therapy and reductions in low-density lipoprotein cholesterol: Initial clinical data on the potent new statin rosuvastatin2001In: American Journal of Cardiology, ISSN 0002-9149, E-ISSN 1879-1913, Vol. 87, no 5 SUPPL. 1Article in journal (Refereed)
    Abstract [en]

    The utility of statins with increased potency in reducing low-density lipoprotein cholesterol (LDL-C) is indicated by evidence that aggressive LDL-C lowering is associated with increased reduction in coronary artery disease risk, and the need for such agents is illustrated by the fact that many patients currently fail to achieve LDL-C target levels during treatment with available drugs. In dose-ranging studies of patients with hypercholesterolemia, the new synthetic statin rosuvastatin (formerly ZD4522) produced significant, dose-dependent reductions in LDL-C compared with placebo across a range of doses. Reductions ranged from 34% at 1 mg per day to 65% at 80 mg per day, with linear regression analysis indicating an additional 4.5% reduction in LDL-C with each doubling of the rosuvastatin dose. Rosuvastatin treatment was well tolerated. Phase 3 clinical trials of this agent are under way.

    Comparison of the efficacy and tolerability of fluvastatin extended-release and immediate-release formulations in the treatment of primary hypercholesterolemia: A randomized trial2001In: Clinical Therapeutics, ISSN 0149-2918, E-ISSN 1879-114X, Vol. 23, no 1, p. 45-61Article in journal (Refereed)
    Abstract [en]

    Background: A new extended-release (ER) formulation of fluvastatin 80 mg has been developed for once-daily treatment of primary hypercholesterolemia. Objective: The purpose of this study was to compare the lipid-lowering efficacy and tolerability of fluvastatin ER (80 mg once daily) versus fluvastatin immediate-release (IR) (40 mg once or twice daily). Methods: Following a 4-week placebo/dietary run-in period, patients with primary hypercholesterolemia type IIa or IIb (low-density lipoprotein cholesterol [LDL-C] =160 mg/dL and triglycerides [TG] =400 mg/dL) were randomized (2:1:1) to receive fluvastatin ER 80 mg once daily at bedtime (QPM), fluvastatin IR 40 mg QPM, or fluvastatin IR 40 mg BID for 24 weeks. Patients who had homozygous familial hypercholesterolemia, type I, III, IV, V, or secondary hyperlipoproteinemia, diabetes, or evidence of liver or renal impairment were excluded. At weeks 0, 2, 4, 8, 12, 16, 20, and 24 of the active-treatment period, levels of LDL-C, high-density lipoprotein cholesterol (HDL-C), TG, and total cholesterol (TC) were measured. Results: Of the 1183 patients enrolled, 695 were randomly assigned to treatment, 346 to fluvastatin ER 80 mg QPM, 174 to fluvastatin IR 40 mg QPM, and 175 to fluvastatin IR 40 mg BID. Patients were well matched between groups, with a mean age of-56 years and body mass index of 27 kg/m2, 56.0% of patients (389/695) were female and 97.7% (679/695) were white. Fluvastatin ER 80 mg QPM lowered LDL-C levels significantly more than did fluvastatin IR 40 mg QPM (33.7% vs 24.4%, P < 0.001) and as effectively as fluvastatin IR 40 mg BID (33.9%). More than half of the patients administered fluvastatin ER 80 mg QPM and IR 40 mg BID achieved reductions in LDL-C levels of =35%, more than half of those administered fluvastatin IR 40 mg QPM experienced reductions in LDL-C levels of =25%. The mean reductions in LDL:HDL ratio, TC, and apolipoprotein B levels in the fluvastatin ER 80 mg QPM group were significantly greater than the reductions in the IR 40 mg QPM group (P < 0.001). In patients with mixed dyslipidemia, fluvastatin ER 80 mg reduced triglycerides by 21.8% (median 28%) and increased HDL-C by 14.5%. Fluvastatin ER 80 mg QPM was well tolerated, with incidences of clinically notable elevations in alanine aminotransferase, aspartate aminotransferase, and creatine kinase levels and musculoskeletal adverse events comparable to those in the IR 40 mg QPM group. Conclusion: The ER 80-mg formulation of fluvastatin is effective and well tolerated as a once-daily starting and maintenance treatment for primary hypercholesterolemia.

    Prognostic factors for the course of beta cell function in autoimmune diabetes2000In: Journal of Clinical Endocrinology and Metabolism, ISSN 0021-972X, E-ISSN 1945-7197, Vol. 85, no 12, p. 4619-4623Article in journal (Refereed)
    Abstract [en]

    This study presents a 2-yr follow-up of 281 patients, aged 15-34 yr, diagnosed with diabetes between 1992 and 1993. At diagnosis, 224 (80%) patients were positive for at least one of the following autoantibodies: islet cell antibodies (ICAs), glutamic acid decarboxylase antibodies (GADAs), or tyrosine phosphatase antibodies (IA-2As), the remaining 57 (20%) patients were negative for all three autoantibodies. At diagnosis, C-peptide levels were lower (0.27, 0.16-0.40 nmol/L) in autoantibody-positive patients compared with autoantibody-negative patients (0.51, 0.28-0.78 nmol/L, P < 0.001). After 2 yr, C-peptide levels had decreased significantly in patients with autoimmune diabetes (0.20, 0.10-0.37 nmol/L, P = 0.0018), but not in autoantibody-negative patients. In patients with autoimmune diabetes, a low initial level of C-peptide (odds ratio, 2.6, 95% confidence interval, 1.7-4.0) and a high level of GADAs (odds ratio, 2.5, 95% confidence interval, 1.1-5.7) were risk factors for a C-peptide level below the reference level of 0.25 nmol/L 2 yr after diagnosis. Body mass index had a significant effect in the multivariate analysis only when initial C-peptide was not considered. Factors such as age, gender, levels of ICA or IA-2A or insulin autoantibodies (analyzed in a subset of 180 patients) had no effect on the decrease in ▀-cell function. It is concluded that the absence of pancreatic islet autoantibodies at diagnosis were highly predictive for a maintained ▀-cell function during the 2 yr after diagnosis, whereas high levels of GADA indicated a course of decreased ▀-cell function with low levels of C-peptide. In autoimmune diabetes, an initial low level of C-peptide was a strong risk factor for a decrease in ▀-cell function and conversely high C-peptide levels were protective. Other factors such as age, gender, body mass index, levels of ICA, IA-2A or IAA had no prognostic importance.

    Glutamic acid decarboxylase antibodies (GADA) is the most important factor for prediction of insulin therapy within 3 years in young adult diabetic patients not classified as Type 1 diabetes on clinical grounds2000In: Diabetes/Metabolism Research Reviews, ISSN 1520-7552, E-ISSN 1520-7560, Vol. 16, no 6, p. 442-447Article in journal (Refereed)
    Abstract [en]

    Background Differentiation between Type 1 and Type 2 diabetes in adults is difficult at diagnosis. In this study we tested the hypothesis that autoantibodies at diagnosis are predictive for insulin treatment within 3 years in patients initially not classified as Type 1 diabetes. Methods In a nationwide population-based study, blood samples were obtained from 764 patients, all diagnosed with diabetes during a 2-year period. At diagnosis, 583 (76%) were classified as Type 1, 110 (14%) as Type 2 and 71 (9.3%) could not be classified. Results Among patients not classified as Type 1 diabetes, 52 (47%) of Type 2 and 42 (59%) of unclassified patients were positive for islet cell antibodies CICA), glutamic acid decarboxylase antibodies (GADA) or tyrosine phosphatase antibodies (IA-2A). These patients (n=94) had lower body mass index (BMI) (p<0.001) and lower C-peptide (p<0.001) compared to the autoantibody negative patients (n=87). Compared to clinically classified Type 1 diabetes patients positive for autoantibodies (n=477), they have higher BMI (p<0.001), higher C-peptide (p<0.001) and the same levels of ICA, GADA and IA-2A. After 3 years, 93% of autoantibody positive patients initially not classified as Type 1 were on insulin. When ICA, GADA, IA-2A, BMI and C-peptide were tested in a multiple logistic regression, only GADA was signiificant for insulin treatment within 3 years (OR = 18.8, 95% CI 1.8-191) in patients treated with diet or oral drugs at diagnosis. Conclusions A correct classification is difficult in adult diabetic patients. The presence of pancreatic autoantibodies, especially GADA, at diagnosis of diabetes are highly predictive for insulin therapy within 3 years from diagnosis. Copyright ⌐ 2000 John Wiley & Sons, Ltd.

    Increased mortality in diabetes during the first 10 years of the disease. A population-based study (DISS) in Swedish adults 15-34 years old at diagnosis2001In: Journal of Internal Medicine, ISSN 0954-6820, E-ISSN 1365-2796, Vol. 249, no 3, p. 263-270Article in journal (Refereed)
    Abstract [en]

    Objectives. To study, prospectively, in young adult patients, the mortality during the first years after the diagnosis of diabetes. Design. The Diabetes Incidence Study in Sweden (DISS) aims to register all incident cases aged 15-34 years. During a 10-year period all deaths were identified by record linkage to the national Cause of Death Registry. Subjects. During the period, 4097 new cases were registered and classified as type 1 diabetes (73%), type 2 (16%), secondary (2%) and unclassified (9%). The median follow-up was 5 years (21 001 person-years). Main outcome measures. Calculation of the standardized mortality ratio (SMR) and 95% confidence interval (CI). Evaluation of all deceased by scrutiny of clinical records, death certificates and autopsy protocols. Results. Fifty-eight patients died, corresponding to an SMR of 3.5 (CI = 2.7-4.5), which increased from 1.5 at 15-19 years to 4.1 at 30-34 years. SMR was 2.7 in primary diabetes: 2.3 (1.6-3.3) in type 1 and 4.1 (2.6-6.7) in type 2. In secondary diabetes, alcohol-associated pancreatitis a common cause, SMR was 32 (CI = 24-45). Evidence of alcohol or drug misuse, mental dysfunction or suicide was found in 40 of all 58 deceased cases. Less often, hypoglycaemia (n = 7) or hyperglycaemia-ketoacidosis (n = 11) was present at death. Unexplained 'dead in bed' was found once. Conclusions. In the investigated population-based cohort the early mortality was about threefold increased. Hypoglycaemia and ketoacidosis per se played a relatively small role compared with a heavy impact from social and mental dysfunction, and from careless use of alcohol or drugs.

    Ketoacidosis in young adults is not related to the islet antibodies at the diagnosis of Type 1 diabetes mellitus - A nationwide study2000In: Diabetic Medicine, ISSN 0742-3071, E-ISSN 1464-5491, Vol. 17, no 4, p. 269-274Article in journal (Refereed)
    Abstract [en]

    Aims: To test the hypothesis that there is lower prevalence of islet antibodies in subjects with newly diagnosed Type 1 diabetes mellitus in young adulthood than in children is associated with less severe diabetes at time of diagnosis. Methods: This investigation was based on a nationwide study (Diabetes Incidence Study in Sweden) of 15-34-year-old newly diagnosed diabetic subjects. During 1992-1993, all diabetic subjects (excluding secondary and gestational diabetes) were reported on standardized forms, with information about clinical characteristics at diagnosis. The study examined islet cell antibodies (ICA) by indirect immunofluorescence, and autoantibodies to glutamic acid decarboxylase (GADA), tyrosine phosphatase- like antigen (IA-2A) and insulin (IAA) as well as C-peptide by radioimmunoassay. Results: Blood samples were available from 78 patients with diabetic ketoacidosis (DKA) and 517 non-acidotic patients. The prevalence of ICA (63% vs. 57%), GADA (63% vs. 66%), IA-2A (35% vs. 44%) and IAA (20% vs. 15%) were very similar in patients with or without DKA. The median levels of the four autoantibodies did not differ between the two groups. High blood glucose (P < 0.001) and low C-peptide levels (P < 0.001) were the only parameters found to be related to DKA. Conclusions: The similarities in findings of newly diagnosed diabetic patients with or without DKA regarding ICA, GADA, IA-2A and IAA suggest that there is no relationship between the expression of antigenicity and the severity of ▀-cell dysfunction. The lower prevalence of the four autoantibodies in 15-34-year-old diabetic subjects compared with previous findings in children is not explained by misclassification of diabetes type.
