- OBJECTIVES To compare the risk associated with systolic blood pressure that meets current recommendations (that is, below 140 mm Hg) with the risk associated with lower levels in patients who have type 2 diabetes and no previous cardiovascular disease. Population based cohort study with nationwide clinical registries, 2006-12. The mean follow-up was 5.0 years. 187 106 patients registered in the Swedish national diabetes register who had had type 2 diabetes for at least a year, age 75 or younger, and with no previous cardiovascular or other major disease. Clinical events were obtained from the hospital discharge and death registers with respect to acute myocardial infarction, stroke, a composite of acute myocardial infarction and stroke (cardiovascular disease), coronary heart disease, heart failure, and total mortality. Hazard ratios were estimated for different levels of baseline systolic blood pressure with clinical characteristics and drug prescription data as covariates. The group with the lowest systolic blood pressure (110-119 mm Hg) had a significantly lower risk of non-fatal acute myocardial infarction (adjusted hazard ratio 0.76, 95% confidence interval 0.64 to 0.91; P=0.003), total acute myocardial infarction (0.85, 0.72 to 0.99; P=0.04), non-fatal cardiovascular disease (0.82, 0.72 to 0.93; P=0.002), total cardiovascular disease (0.88, 0.79 to 0.99; P=0.04), and non-fatal coronary heart disease (0.88, 0.78 to 0.99; P=0.03) compared with the reference group (130-139 mm Hg). There was no indication of a J shaped relation between systolic blood pressure and the endpoints, with the exception of heart failure and total mortality. Lower systolic blood pressure than currently recommended is associated with significantly lower risk of cardiovascular events in patients with type 2 diabetes. The association between low blood pressure and increased mortality could be due to concomitant disease rather than antihypertensive treatment.

- AIM: To examine the prevalence and the clinical characteristics associated with normoalbuminuric renal impairment (RI) in a general type 2 diabetes (T2D) population. METHODS: We included 94 446 patients with T2D (56% men, age 68.3±11.6years, BMI 29.6±5.3kg/m(2), diabetes duration 8.5±7.1years; means±SD) with renal function (serum creatinine) reported to the Swedish National Diabetes Register (NDR) in 2009. RI was defined as estimated glomerular filtration (eGFR)<60ml/min/1.73m(2) and albuminuria as a urinary albumin excretion rate (AER)>20μg/min. We linked the NDR to the Swedish Prescribed Drug Register, and the Swedish Cause of Death and the Hospital Discharge Register to evaluate ongoing medication and clinical outcomes. RESULTS: 17% of the patients had RI, and 62% of these patients were normoalbuminuric. This group of patients had better metabolic control, lower BMI, lower systolic blood pressure and were more often women, non-smokers and more seldom had a history of cardiovascular disease as compared with patients with albuminuric RI. 28% of the patients with normoalbuminuric RI had no ongoing treatment with any RAAS-blocking agent. Retinopathy was most common in patients with RI and albuminuria (31%). CONCLUSIONS: The majority of patients with type 2 diabetes and RI were normoalbuminuric despite the fact that 25% of these patients had no ongoing treatment with RAAS-blocking agents. Thus, RI in many patients with type 2 diabetes is likely to be caused by other factors than diabetic microvascular disease and ongoing RAAS-blockade.

- Context Patients with type 1 diabetes mellitus (T1DM) have an increased risk of Addison disease (AD) development, but prediction of those at risk is not possible. Objective To determine whether there are early clinical indicators that may denote the development of AD in adults with T1DM. Design Observational, matched-cohort study. Setting Patient data from Swedish national registries [National Diabetes Register (NDR), Inpatient Register, and Prescription Drug Register]. Participants All patients with T1DM diagnosed with concomitant AD (n = 66) among the 36,514 adult patients with T1DM in the NDR between 1998 and 2013. Each case was matched to five controls with T1DM alone (n = 330). Main Outcome Measures Clinical data and drug prescriptions were assessed prior to baseline (inclusion into the study) and prior to AD diagnosis. Analysis of covariance and estimated group proportions were used for comparisons. Results Prior to baseline, cases had a higher frequency of thyroid/antithyroid drug prescription than controls (9.1% vs 1.8%). Prior to AD diagnosis, cases had higher frequencies of diabetic retinopathy (12.1% vs 2.1%), infections requiring hospital admission (16.7% vs 2.1%), thyroid/antithyroid drug prescription (28.8% vs 7.0%), and glucagon prescription (18.2% vs 6.4%). There was no difference in glycated Hb between the groups prior to baseline or prior to AD diagnosis. Conclusions These data suggest that medical treatment of thyroid disease, a severe infection, and glucagon prescription for severe hypoglycemia should raise the suspicion of AD development in adults with T1DM. Development of diabetic retinopathy might also be associated with glucocorticoid deficiency and the development of AD among patients with T1DM.

- We determined the incidence and prevalence of Addison's disease (AD) among persons with or without type 1 diabetes mellitus (T1DM) in nationwide, matched cohort studies.Persons with T1DM were identified from the Swedish National Diabetes Register and each was matched for age, sex, year and county to five controls randomly selected from the general population. Persons with AD were identified from the Swedish National Inpatient Register. Baseline demographics and seasonal onset variation of AD were presented by descriptive statistics. Prevalence and incidence were estimated by proportions and incidence rates, respectively. Times to AD were analyzed using the Cox proportional hazard model.Between 1998 and 2013, 66 persons with T1DM were diagnosed with AD at a mean age (s.d.) of 36.4 (13.0) years among 36 514 persons with T1DM, while 32 were diagnosed with AD at a mean age of 42.7 (15.2) years among 182 570 controls. The difference in mean age at diagnosis of AD between the groups was 6.3 years (P value=0.036). The incidence of AD for a person with or without T1DM was therefore 193 and 18 per million person-years, respectively. The adjusted relative risk increase of developing AD in T1DM was 10.8 (95% CI: 7.1-16.5). The highest incidence of AD was observed during February-March and September-October. The prevalence of AD in persons with or without T1DM in December 2012 was 3410 and 208 per million, respectively. The odds ratio for AD in persons with T1DM vs controls was 16.5 (95% CI: 11.1-24.5).The risk to develop AD among persons with T1DM is more than 10 times higher than in persons without T1DM. Persons with T1DM develop AD at a younger age. The incidence of AD may have a seasonal pattern.

- Our hypothesis was that patients with diabetes mellitus obtain an additional risk of death if they develop Addison's disease (AD).Nationwide, matched, observational cohort study cross-referencing the Swedish National Diabetes Register with Inpatient, Cancer and Cause of Death Registers in patients with diabetes (type 1 and 2) and AD and matched controls with diabetes. Clinical characteristics at baseline, overall, and cause-specific mortality were assessed. The relative risk of death was assessed using a Cox proportional hazards regression model.Between January 1996 and December 2012, 226 patients with diabetes and AD were identified and matched with 1129 controls with diabetes. Median (interquartile range) follow-up was 5.9 (2.7-8.6) years. When patients with diabetes were diagnosed with AD, they had an increased frequency of diabetes complications, but both medical history of cancer and coronary heart disease did not differ compared with controls. Sixty-four of the 226 patients with diabetes and AD (28%) died, while 112 of the 1129 controls (10%) died. The estimated relative risk increase (hazard ratio) in overall mortality in the diabetes and AD group was 3.89 (95% confidence interval 2.84-5.32) compared with controls with diabetes. The most common cause of death was cardiovascular in both groups, but patients with diabetes and AD showed an increased death rate from diabetes complications, infectious diseases and unknown causes.Patients with the rare combination of diabetes and AD showed a markedly increased mortality and died more frequently from infections and unknown causes than patients with diabetes alone. Improved strategy for the management of this combination of metabolic disorders is needed.

Tidskriftsartikel (refereegranskat)abstract
- Aim: To investigate the relative safety of various glucose-lowering agents as add-on medication to metformin in type 2 diabetes in an observational study linking five national health registers. Research design and methods: Patients with type 2 diabetes who had been on metformin monotherapy and started another agent in addition to metformin were eligible for inclusion. The study period was 2005-2012. Adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) of mortality, cardiovascular disease (CVD), coronary heart disease (CHD), stroke and congestive heart failure (CHF) were estimated using Cox proportional hazards models, weighted for a propensity score. Results: Of the 20 422 patients included in the study, 43% started on second-line treatment with sulphonylurea (SU), 21% basal insulin, 12% thiazolidinedione (TZD), 11% meglitinide, 10% dipeptidyl peptidase-4 (DPP-4) inhibitor, 1% glucagon-like peptide-1 (GLP-1) receptor agonist and 1% acarbose. At the index date, the mean patient age was similar to 60 years for all groups except the GLP-1 receptor agonist (56.0 years) and SU (62.9 years) groups. Diabetes duration and glycated haemoglobin levels were similar in all groups. When compared with SU, basal insulin was associated with an 18% higher risk and TZD with a 24% lower risk of mortality [HR 1.18 (95% CI 1.03-1.36) and 0.76 (95% CI 0.62-0.94)], respectively. DPP-4 inhibitor treatment was associated with significantly lower risks of CVD, fatal CVD, CHD, fatal CHD and CHF. Conclusions: This nationwide observational study showed that second-line treatment with TZD and DPP-4 inhibitor as add-on medication to metformin were associated with significantly lower risks of mortality and cardiovascular events compared with SU, whereas basal insulin was associated with a higher risk of mortality.

- Aims: To analyse clinical characteristics and treatment results in unselected type 2 diabetes mellitus (T2DM) patients, with non-pharmacological treatment as well as the most commonly used pharmacological glucose-lowering treatment regimens, in everyday clinical practice. Methods: In this population-based cross-sectional study, information was linked from the Swedish National Diabetes Register, Prescribed Drug Register and Patient Register. T2DM patients with non-pharmacological treatment and T2DM patients continuously using the 12 most common pharmacological treatment regimens were included in the study (n = 163121). Results: There were statistically significant differences in clinical characteristics between the groups. Patients with insulin-based treatment regimens had the longest duration of diabetes and more cardiovascular risk factors than the T2DM-population in general. The proportion of patients reaching HbA1c =7% varied between 70.1% (metformin) and 25.0% [premixed insulin (PMI) + SU) in patients with pharmacological treatment. 84.8% of the patients with non-pharmacological treatment reached target. Compared to patients on metformin, patients on other pharmacological treatments had a lower likelihood, with hazard ratios ranging from 0.58; 95% confidence interval (CI), 0.540.63 to 0.97;0.940.99, of having HbA1c =7% (adjusted for covariates). Patients on insulin-based treatments had the lowest likelihood, while non-pharmacological treatment was associated with an increased likelihood of having HbA1c =7%. Conclusion: This nation-wide study shows insufficiently reached treatment goals for haemoglobin A1c (HbA1c) in all treatment groups. Patients on insulin-based treatment regimens had the longest duration of diabetes, more cardiovascular risk factors and the highest proportions of patients not reaching HbA1c target.

Tidskriftsartikel (refereegranskat)abstract
- Aims/hypothesis Dyslipidemia is an important modifiable risk factor and lipid-lowering treatment (LLT) is essential to reduce the risk of cardiovascular disease (CVD). Studies in type 2 diabetes indicate that low adherence to statin therapy is a barrier to reach full protective potential, and less is known in type 1 diabetes (T1D). The aim was to assessrisk of CVD by adherence and nonpersistence to LLT in T1D. Method A population-based study with a retrospective longitudinal design was conducted between 2006 and 2010, with follow-up until December 2013. In total, 6192 adult individuals withT1D, initiatingLLTbetween 2006 and 2010, were included.Information on LLT, socioeconomic characteristics, comorbidities and cardiovascular eventswere collected. After 18 months, refill adherence was estimated by calculating medication possession ratio (MPR). Nonpersistence was defined as being without medicines on hand for at least 180 days. Individuals were thereafterfollowed untilCVD, deathorend of follow-up in December 2013. Cox regression analyses were performed to assess adherence level and nonpersistence of LLT as predictor ofCVD. Analyses wereadjusted for cardiovascular risk factors andsocioeconomic status. Results Mean MPRwas 72%, 52% of the participants had an MPR above 80% and 27% discontinued LLT. There were 637nonfataland58 fatal CVDevents, mean follow-up 3.6 and 3.9 years, respectively. MPR above 80% was associated with reduced risk for nonfatal CVD compared with lower MPR, HR 0.78 (95% CI 0.65 to 0.93)). For fatal CVD, results indicated a negative effect of high adherence but the association did not reach statistical significance, HR 1.96 (0.96 to 4.01). Individuals discontinuing LLT had higher risk of nonfatal CVD, HR 1.43 (95% CI 1.18 to 1.73). Conclusions/Interpretation In T1D, the risk for nonfatal CVD was lower among individuals with high adherence and higher among those discontinuing LLT within 18 months. It is important to evaluate andemphasize adherence toprescribedLLTat clinical visits to achieve treatment goals and reduce the risk of CVD. © Author(s) (or their employer(s)) 2020.
