- 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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

- 2021
-
Ingår i: Vasa - European Journal of Vascular Medicine. - : Hogrefe Publishing Group. - 0301-1526. ; 50:3, s. 224-230

Tidskriftsartikel (refereegranskat)abstract
- Summary: Background: Diabetes mellitus (DM) is a risk factor for peripheral arterial disease (PAD). Indications for open surgery in infrainguinal intermittent claudication (IC) are limited, and reports are lacking regarding outcomes in DM patients. Study aims were to compare short and long-term effects on major adverse cardiovascular events (MACE), acute myocardial infarction (AMI), stroke, major amputation, and mortality after infrainguinal open surgery for IC in patients with and without DM, and to evaluate relationships between glycaemic control and outcomes. Methods: Nationwide observational cohort study of all patients registered in the Swedish Vascular Registry after planned infrainguinal open surgery for IC from January 1st 2010 to December 31st 2014. Patients registered in the National Diabetes Registry were compared with patients without diabetes by propensity score adjusted comparison of MACE, AMI, stroke, major amputation, and mortality. Results: After 30 days, there were no differences in MACE, AMI, stroke, major amputation, or mortality between patients with (n = 323, mean age 70.5 [SD 7.4] years, 92 [28.5%] females) and without (n = 679, mean age 69.7 years [SD 11.2], 234 [34.5%] females) DM. At last follow-up after median 5.2 years, patients with DM showed higher rates of MACE (Hazard ratio [HR] 1.33, confidence interval [CI] 1.08-1.62; p < 0.01), and AMI (HR 2.21, CI 1.46-3.35; p < 0.01) than patients without diabetes. Among DM patients, higher glycated haemoglobin (HbA1c) was associated with higher rates of MACE (HR 1.02, CI 1.00-1.03; p = 0.02), stroke (HR 1.05, CI 1.00-1.11; p = 0.04), and total mortality (HR 1.03, CI 1.01-1.06; p < 0.01), during follow-up, whereas duration of diabetes was associated with higher rate of major amputation (HR 1.08, CI 1.02-1.15; p < 0.01). Conclusions: DM patients showed higher rates of MACE and AMI in propensity score adjusted analysis five years after planned infrainguinal open surgery for IC. Higher HbA1c was associated with MACE, stroke, and total mortality in patients with DM, whereas longer duration of DM was associated with major amputation.

- Objectives To investigate the benefits and risks associated with aspirin treatment in patients with type 2 diabetes and no previous cardiovascular disease (CVD) in clinical practice. Design Population-based cohort study between 2005 and 2009, mean follow-up 3.9years. Setting Hospital outpatient clinics and primary care in Sweden. Participants Men and women with type 2 diabetes, free from CVD, including atrial fibrillation and congestive heart failure, at baseline, registered in the Swedish National Diabetes Register, with continuous low-dose aspirin treatment (n=4608) or no aspirin treatment (n=14038). Main outcome measures Risks of CVD, coronary heart disease (CHD), stroke, mortality and bleedings, associated with aspirin compared with no aspirin, were analysed in all patients and in subgroups by gender and estimated cardiovascular risk. Propensity scores were used to adjust for several baseline risk factors and characteristics at Cox regression, and the effect of unknown covariates was evaluated in a sensitivity analysis. Results There was no association between aspirin use and beneficial effects on risks of CVD or death. Rather, there was an increased risk of non-fatal/fatal CHD associated with aspirin; HR 1.19 (95% CI 1.01 to 1.41), p=0.04. The increased risk of cardiovascular outcomes associated with aspirin was seen when analysing women separately; HR 1.41 (95% CI 1.07 to 1.87), p=0.02, and HR 1.28 (95% CI 1.01 to 1.61), p=0.04, for CHD and CVD, respectively, but not for men separately. There was a trend towards increased risk of a composite of bleedings associated with aspirin, n=157; HR 1.41 (95% CI 0.99 to 1.99). Conclusions The results support the trend towards more restrictive use of aspirin in patients with type 2 diabetes and no previous CVD. More research is needed to explore the differences in aspirin's effects in women and men.

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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

- Diabetes is a major risk factor for cardiovascular disease and death but its effect on outcomes in acromegaly is unknown.This work aimed to study whether diabetes affects morbidity and mortality in patients with acromegaly.A nationwide (Sweden), observational, matched-cohort study was conducted. Patients diagnosed with acromegaly between 1987 and 2020 were identified in the Swedish National Patient Registry and those with concomitant type 2 diabetes in the National Diabetes Registry and Drug Registry. The risk of overall mortality, and cardiovascular mortality and morbidity were estimated using Cox regression.The study included 254 patients with acromegaly and concomitant type 2 diabetes (ACRO-DM group) and 532 without diabetes (ACRO group). Mean (SD) age at baseline was 62.6 (11.4) and 60.0 (12.1) years (P=.004) and the mean (SD) duration of acromegaly was 6.8 (8.1) and 6.0 (6.2) years (P=.098) in the ACRO-DM and ACRO groups, respectively. Overall mean follow-up was 9.2 years. The unadjusted overall mortality rate per 1000 person-years was 35.1 (95% CI, 27.2-44.7) and 20.1 (95% CI, 16.5-24.3) in the respective groups. The hazard ratio (HR) for overall mortality adjusted for multiple confounders was 1.58 (95% CI, 1.12-2.23) in the ACRO-DM group compared with the ACRO group. Cardiovascular mortality (HR 2.11; 95% CI, 1.09-4.10) and morbidity (HR 1.49; 95% CI, 1.21-1.82) were also increased in the ACRO-DM group.The presence of diabetes in patients with acromegaly was associated with increased overall mortality as well as increased cardiovascular mortality and morbidity.

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.

- OBJECTIVE: To study the potential long-term benefits and possible complications of bariatric surgery in patients with type 1 diabetes (T1D).RESEARCH DESIGN AND METHODS: In this register-based nationwide cohort study, we compared individuals with T1D and obesity who underwent Roux-en-Y gastric bypass (RYGB) surgery with patients with T1D and obesity matched for age, sex, BMI, and calendar time that did not undergo surgery. By linking the Swedish National Diabetes Register and Scandinavian Obesity Surgery Registry study individuals were included between 2007 and 2013. Outcomes examined included all-cause mortality, cardiovascular disease, stroke, heart failure, and hospitalization for serious hypo- or hyperglycemic events, amputation, psychiatric disorders, changes in kidney function, and substance abuse.RESULTS: We identified 387 individuals who had undergone RYGB and 387 control patients. Follow-up for hospitalization was up to 9 years. Analysis showed lower risk for cardiovascular disease (hazard ratio [HR] 0.43; 95% CI 0.20-0.9), cardiovascular death (HR 0.15; 95% CI 0.03-0.68), hospitalization for heart failure (HR 0.32; 95% CI 0.15-0.67) and stroke (HR 0.18; 95% CI 0.04-0.82) for the RYGB group. There was a higher risk for serious hyperglycemic events (HR 1.99; 95% CI 1.07-3.72) and substance abuse (HR 3.71; 95% CI 1.03-3.29) after surgery.CONCLUSIONS: This observational study suggests bariatric surgery may yield similar benefits on risk for cardiovascular outcomes and mortality in patients with T1D and obesity as for patients with type 2 diabetes. However, some potential serious adverse effects suggest need for careful monitoring of such patients after surgery.

Tidskriftsartikel (refereegranskat)abstract
- Background: Obesity and diabetes mellitus are strongly associated with heart failure (HF) and atrial fibrillation (AF). The benefits of bariatric surgery on cardiovascular outcomes are known in people with or without diabetes mellitus. Surgical treatment of obesity might also reduce the incidence of HF and AF in individuals with obesity and type 2 diabetes mellitus (T2DM).Methods and Results: In this register-based nationwide cohort study we compared individuals with T2DM and obesity who underwent Roux-en-Y gastric bypass surgery with matched individuals not treated with surgery. The main outcome measures were hospitalization for HF and/or AF and mortality in patients with preexisting HF. We identified 5321 individuals with T2DM and obesity who had undergone Roux-en-Y gastric bypass surgery between January 2007 and December 2013 and 5321 matched controls. The individuals included were 18 to 65 years old and had a body mass index >27.5 kg/m2. The follow-up time for hospitalization was until the end of 2015 (mean 4.5 years) and the end of 2016 for death. Our results show a 73% lower risk for HF (hazard ratio [HR], 0.27; CI, 0.19-0.38), 41% for AF (HR, 0.59; CI, 0.44-0.78), and 77% for concomitant AF and HF (HR, 0.23; CI, 0.12-0.46) in the surgically treated group. In patients with preexisting HF we observed significantly lower mortality in the group who underwent surgery (HR, 0.23; 95% CI, 0.12-0.43).Conclusion:s Bariatric surgery may reduce risk for HF and AF in patients with T2DM and obesity, speculatively via positive cardiovascular and renal effects. Obesity treatment with surgery may also be a valuable alternative in selected patients with T2DM and HF.

- To analyse the association between refill adherence to lipid-lowering medications, and the risk of cardiovascular disease (CVD) and mortality in patients with type 2 diabetes mellitus.Cohort study.National population-based cohort of Swedish patients with type 2 diabetes mellitus.86568 patients aged ≥18 years, registered with type 2 diabetes mellitus in the Swedish National Diabetes Register, who filled at least one prescription for lipid-lowering medication use during 2007-2010, 87% for primary prevention.Refill adherence of implementation was assessed using the medication possession ratio (MPR), representing the proportion of days with medications on hand during an 18-month exposure period. MPR was categorised by five levels (≤20%, 21%-40%, 41%-60%, 61%-80% and >80%). Patients without medications on hand for ≥180 days were defined as non-persistent. Risk of CVD (myocardial infarction, ischaemic heart disease, stroke and unstable angina) and mortality by level of MPR and persistence was analysed after the exposure period using Cox proportional hazards regression and Kaplan-Meier, adjusted for demographics, socioeconomic status, concurrent medications and clinical characteristics.The hazard ratios for CVD ranged 1.33-2.36 in primary prevention patients and 1.19-1.58 in secondary prevention patients, for those with MPR ≤80% (p<0.0001). The mortality risk was similar regardless of MPR level. The CVD risk was 74% higher in primary prevention patients and 33% higher in secondary prevention patients, for those who were non-persistent (p<0.0001). The mortality risk was 6% higher in primary prevention patients and 18% higher in secondary prevention patients, for non-persistent patients (p<0.0001).Higher refill adherence to lipid-lowering medications was associated with lower risk of CVD in primary and secondary prevention patients with type 2 diabetes mellitus.

- Management of type 2 diabetes mellitus (T2DM) encompasses intensive glycaemic control, along with treatment of comorbidities and complications to handle the increased risk of cardiovascular disease (CVD). Improved control of LDL-cholesterol (LDL-C) with lipid-lowering medications is associated with reduced CVD risk in T2DM patients. Thus, treatment guidelines recommend lipid-lowering medications for T2DM patients with LDL-C above risk-associated thresholds. This study aimed to assess healthcare provider adherence to guidelines regarding lipid-lowering medication prescription among T2DM patients and to analyse factors associated with lipid-lowering medication prescription.Observations in 2007-2014 for T2DM patients age≥18 were collected from the Swedish National Diabetes Register. Observations were excluded if they lacked information about LDL-C, lipid-lowering medication prescription or CVD. Observations with established CVD were attributed to secondary prevention; remaining observations were attributed to primary prevention. The analyses included primary and secondary prevention observations with LDL-C above risk-associated thresholds (LDL-C≥2.5mmol/l and LDL-C≥1.8mmol/l respectively). Guideline adherence was analysed as the probability of prescribing lipid-lowering medications using mixed-effect model regression adjusted for potential confounders. Factors associated with prescribing lipid-lowering medications were analysed for patient and healthcare provider characteristics using mixed-effect model regression and odds ratio.A total of 1,204,376 observations from 322,046 patients reported by 1352 healthcare providers were included. Primary prevention accounted for 63%; 52% were men, mean age was 64 and mean LDL-C was 3.4mmol/l. For secondary prevention, 60% were men, mean age was 72 and mean LDL-C was 2.7mmol/l. During 2007-2014, guideline adherence ranged from 36 to 47% for primary prevention and 59 to 69% for secondary prevention. In general, concomitant prescription of diabetes medications, antiplatelets and antihypertensives along with smoking and specialised care were associated with higher prescription of lipid-lowering medications. Patients age≥80 were associated with lower prescription of lipid-lowering medications. Higher prescription was associated with longer diabetes duration in primary prevention and men in secondary prevention.Adherence to treatment guidelines levelled off after an initial increase in both prevention groups. Lipid-lowering medication prescription was based on individualised CVD risk.

- This study aimed to describe and compare refill adherence and persistence to lipid-lowering medicines in patients with type 2 diabetes by previous cardiovascular disease (CVD).We followed 97595 patients (58% men; 23% with previous CVD) who were 18years of age or older when initiating lipid-lowering medicines in 2007-2010 until first fill of multi-dose dispensed medicines, death, or 3years. Using personal identity numbers, we linked individuals' data from the Swedish Prescribed Drug Register, the Swedish National Diabetes Register, the National Patient Register, the Cause of Death Register, and the Longitudinal Integration Database for Health Insurance and Labour Market Studies. We assessed refill adherence using the medication possession ratio (MPR) and the maximum gap method, and measured persistence from initiation to discontinuation of treatment or until 3years after initiation. We analyzed differences in refill adherence and persistence by previous CVD in multiple regression models, adjusted for socioeconomic status, concurrent medicines, and clinical characteristics.The mean age of the study population was 64years, 80% were born in Sweden, and 56% filled prescriptions for diabetes medicines. Mean MPR was 71%, 39% were adherent according to the maximum gap method, and mean persistence was 758days. Patients with previous CVD showed higher MPR (3%) and lower risk for discontinuing treatment (12%) compared with patients without previous CVD (P<0.0001).Patients with previous CVD were more likely to be adherent to treatment and had lower risk for discontinuation compared with patients without previous CVD.

- Objective To analyze the risk of cardiovascular (CV) events and mortality in relation to adherence to lipid-lowering medications by healthcare centers and patients with type 2 diabetes mellitus (T2DM). Research design and methods We included 121914 patients (12% secondary prevention) with T2DM reported by 1363 healthcare centers. Patients initiated lipid-lowering medications between July 2006 and December 2012 and were followed from cessation of the first filled supply until multidose dispensed medications, migration, CV events, death or December 2016. The study period was divided into 4-month intervals through 2014, followed by annual intervals through 2016. Adherence measures were assessed for each interval. Patients’ (refill) adherence was measured using the medication possession ratio (MPR). Healthcare centers’ (guideline) adherence represented the prescription prevalence of lipid-lowering medications according to guidelines. The risk of CV events and mortality was analyzed for each interval using Cox proportional hazard regression and Kaplan-Meier. Results Compared with high-adherent patients (MPR >80%), low-adherent primary prevention patients (MPR ≤80%) showed higher risk of all outcomes: 44%–51 % for CV events, doubled for all-cause mortality and 79%–90% for CV mortality. Corresponding risks for low-adherent secondary prevention patients were 17%–19% for CV events, 88%–97% for all-cause and 66%–79% for CV mortality. Primary prevention patients treated by low-adherent healthcare centers (guideline adherence <48%) had a higher risk of CV events and CV mortality. Otherwise, no difference in the risk of CV events or mortality was observed by guideline adherence level. Conclusions Our results demonstrate the importance of high refill adherence and thus the value of individualized care among patients with T2DM.

- Studies comparing direct-acting insulin analogs (DAIs) in terms of effectiveness and long-term safety are scarce. Our aim was to explore these variables in clinical practice among patients with type 1 diabetes, including the elderly and those with renal impairment. We linked four national registers in a population-based cohort study. Patients with type 1 diabetes and continuous use of all currently available DAIs (lispro, aspart, or glulisine) in 2005-2013 were monitored for up to 7.5 years. Inverse probability of treatment weighting was used to adjust for differences in baseline characteristics between treatment groups. Unadjusted mean HbA1c and weights were plotted. Hazard ratios and 95% confidence intervals of cardiovascular events (CVEs) and mortality were estimated using Cox proportional hazards regression models. We included 41,165 patients-14,047 lispro, 26,813 aspart, and 305 glulisine users. At baseline, the mean age was highest among glulisine users (49.4 years), followed by 41.0 years for lispro users and 40.1 years for aspart users. A total of 9.2% of the patients were 65 years or older. Diabetes duration was shortest among glulisine users (11.6 years), followed by 15.4 years for aspart users and 19.5 years for lispro users. The mean HbA1c and weights during the follow-up period were similar. The numerical differences at baseline were subsequently adjusted for. There were no significant differences between groups regarding hyperglycemia requiring hospitalization, CVE, or mortality, while Cox regression suggested lower rates of hypoglycemia among glulisine users. Severe hypoglycemia was more common, and severe hyperglycemia was less common among patients aged 65 years or older, while severe hypoglycemia and hyperglycemia were more common in patients with low renal function (estimated glomerular filtration rate). There were no pronounced differences in effectiveness and long-term cardiovascular safety and mortality between the DAIs, although there were some differences in clinical characteristics between patients using the three types of insulin. Severe hypoglycemia was more common among older patients, while severe hypoglycemia and hyperglycemia were more common among patients with impaired renal function.

- © Author(s) (or their employer(s)) 2019. Objectives: Long-term effects of gastric bypass (GBP) surgery have been presented in observational and randomised studies, but there are only limited data for persons with obesity and type 2 diabetes mellitus (T2DM) regarding postoperative complications. Design: This is a nationwide observational study based on two quality registers in Sweden (National Diabetes Register, NDR and Scandinavian Obesity Surgery Register, SOReg) and other national databases. Setting: After merging the data, we matched individuals with T2DM who had undergone GBP with those not surgically treated for obesity on propensity score, based on sex, age, body mass index (BMI) and calendar time. The risks of postoperative outcomes (rehospitalisations) were assessed using Cox regression models. Participants: We identified 5321 patients with T2DM in the SOReg and 5321 matched controls in the NDR, aged 18-65 years, with BMI >27.5 kg/m 2 ; and followed for up to 9 years. Primary and secondary outcome measures: We assessed risks for all-cause mortality and hospitalisations for cardiovascular disease, severe kidney disease, along with surgical and other medical conditions. Results: The results agree with the previously suggested lower risks of all-cause mortality (49%) and cardiovascular disease (34%), and we also found positive effects for severe kidney disease but significantly increased risks (twofold to ninefold) of several short-term complications after GBP, such as abdominal pain and gastrointestinal conditions, frequently requiring surgical procedures, apart from reconstructive plastic surgery. Long-term, the risk of anaemia was 92% higher, malnutrition developed approximately three times as often, psychiatric diagnoses were 33% more frequent and alcohol abuse was three times as great as in the control group. Conclusions: This nationwide study confirms the benefits and describes the panorama of adverse events after bariatric surgery in persons with obesity and T2DM. Long-term postoperative monitoring and support, as better selection of patients by appropriate specialists in interdisciplinary settings, should be provided to optimise the outcomes.

- The risk of major amputation is higher after urgently planned endovascular therapy for chronic limb-threatening ischemia (CLTI) in patients with diabetes mellitus (DM). The aim of this nationwide cohort study was to compare outcomes between patients with and without DM following urgently planned open revascularization for CLTI from 2010 to 2014. Out of 1537 individuals registered in the Swedish Vascular Registry, 569 were registered in the National Diabetes Register. A propensity score adjusted Cox regression analysis was conducted to compare outcome between the groups with and without DM. Median follow-up was 4.3 years and 4.5 years for patients with and without DM, respectively. Patients with DM more often had foot ulcers (p = 0.034) and had undergone more previous amputations (p = 0.001) at baseline. No differences in mortality, cardiovascular death, major adverse cardiovascular events (MACE), or major amputation were observed between groups. The incidence rate of stroke was 70% higher (95% CI: 1.11-2.59; p = 0.0137) and the incidence rate of acute myocardial infarction (AMI) 39% higher (95% CI: 1.00-1.92; p = 0.0472) among patients with DM in comparison to those without. Open vascular surgery remains a first-line option for a substantial number of patients with CLTI, especially for limb salvage in patients with DM. The higher incidence rates of stroke and AMI among patients with DM following open vascular surgery for infrainguinal CLTI require specific consideration preoperatively with the aim of optimizing medical treatment to improve cardiovascular outcome postoperatively.

- To investigate the risk of major amputation after elective endovascular therapy in patients with chronic limb threatening ischemia (CLTI) comparing patients with and without diabetes mellitus (DM).In this nationwide cohort study, all patients registered in the Swedish Vascular Register after elective endovascular therapy for CLTI caused by infra-inguinal arterial disease from 2010 to 2014 were included. Among 4578 individuals, 2251 had DM and were registered in the National Diabetes Register between 2009 and 2014. A propensity score adjusted Cox regression analysis was conducted to compare outcomes between groups. Median follow-up was 4.0 and 3.6years for patients with DM and without DM, respectively.The incidence rates of major amputation and acute myocardial infarction (AMI) were 43% (95% CI 1.23-1.67) and 37% (95% CI 1.13-1.67) higher, respectively, among patients with DM compared to patients without DM. There was no difference in mortality (HR 1.04, 95% CI 0.95-1.14).Patients with DM had a higher risk of major amputation and AMI compared to those without DM after elective endovascular therapy for CLTI. Prevention of DM with CLTI is of utmost importance to reduce the risk of adverse limb and cardiovascular outcomes.

- Long-term trends in excess risk of death and cardiovascular outcomes have not been extensively studied in persons with type 1 diabetes or type 2 diabetes.We included patients registered in the Swedish National Diabetes Register from 1998 through 2012 and followed them through 2014. Trends in deaths and cardiovascular events were estimated with Cox regression and standardized incidence rates. For each patient, controls who were matched for age, sex, and county were randomly selected from the general population.Among patients with type 1 diabetes, absolute changes during the study period in the incidence rates of sentinel outcomes per 10,000 person-years were as follows: death from any cause, -31.4 (95% confidence interval [CI], -56.1 to -6.7); death from cardiovascular disease, -26.0 (95% CI, -42.6 to -9.4); death from coronary heart disease, -21.7 (95% CI, -37.1 to -6.4); and hospitalization for cardiovascular disease, -45.7 (95% CI, -71.4 to -20.1). Absolute changes per 10,000 person-years among patients with type 2 diabetes were as follows: death from any cause, -69.6 (95% CI, -95.9 to -43.2); death from cardiovascular disease, -110.0 (95% CI, -128.9 to -91.1); death from coronary heart disease, -91.9 (95% CI, -108.9 to -75.0); and hospitalization for cardiovascular disease, -203.6 (95% CI, -230.9 to -176.3). Patients with type 1 diabetes had roughly 40% greater reduction in cardiovascular outcomes than controls, and patients with type 2 diabetes had roughly 20% greater reduction than controls. Reductions in fatal outcomes were similar in patients with type 1 diabetes and controls, whereas patients with type 2 diabetes had smaller reductions in fatal outcomes than controls.In Sweden from 1998 through 2014, mortality and the incidence of cardiovascular outcomes declined substantially among persons with diabetes, although fatal outcomes declined less among those with type 2 diabetes than among controls.

- Individuals with type 1 diabetes mellitus (T1DM) have a high risk of cardiovascular complications, but it is unknown to what extent fulfilling all cardiovascular treatment goals is associated with residual risk of mortality and cardiovascular outcomes in those with T1DM compared with the general population.We included all patients ≥18 years of age with T1DM who were registered in the Swedish National Diabetes Register from January 1, 1998, through December 31, 2014, a total of 33333 patients, each matched for age and sex with 5 controls without diabetes mellitus randomly selected from the population. Patients with T1DM were categorized according to number of risk factors not at target: glycohemoglobin, blood pressure, albuminuria, smoking, and low-density lipoprotein cholesterol. Risk of all-cause mortality, acute myocardial infarction, heart failure hospitalization, and stroke was examined in relation to the number of risk factors at target.The mean follow-up was 10.4 years in the diabetes group. Overall, 2074 of 33333 patients with diabetes mellitus and 4141 of 166529 controls died. Risk for all outcomes increased stepwise for each additional risk factor not at target. Adjusted hazard ratios for patients achieving all risk factor targets compared with controls were 1.31 (95% confidence interval [CI], 0.93-1.85) for all-cause mortality, 1.82 (95% CI, 1.15-2.88) for acute myocardial infarction, 1.97 (95% CI, 1.04-3.73) for heart failure hospitalization, and 1.17 (95% CI, 0.51-2.68) for stroke. The hazard ratio for patients versus controls with none of the risk factors meeting target was 7.33 (95% CI, 5.08-10.57) for all-cause mortality, 12.34 (95% CI, 7.91-19.48) for acute myocardial infarction, 15.09 (95% CI, 9.87-23.09) for heart failure hospitalization, and 12.02 (95% CI, 7.66-18.85) for stroke.A steep-graded association exists between decreasing number of cardiovascular risk factors at target and major adverse cardiovascular outcomes among patients with T1DM. However, risks for all outcomes were numerically higher for patients with T1DM compared with controls, even when all risk factors were at target, with risk for acute myocardial infarction and heart failure hospitalization statistically significantly higher.

- BACKGROUND: The strength of association and optimal levels for risk factors related to excess risk of death and cardiovascular outcomes in type 1 diabetes mellitus have been sparsely studied. METHODS: In a national observational cohort study from the Swedish National Diabetes Register from 1998 to 2014, we assessed relative prognostic importance of 17 risk factors for death and cardiovascular outcomes in individuals with type 1 diabetes mellitus. We used Cox regression and machine learning analyses. In addition, we examined optimal cut point levels for glycohemoglobin, systolic blood pressure, and low-density lipoprotein cholesterol. Patients with type 1 diabetes mellitus were followed up until death or study end on December 31, 2013. The primary outcomes were death resulting from all causes, fatal/nonfatal acute myocardial infarction, fatal/nonfatal stroke, and hospitalization for heart failure. RESULTS: Of 32 611 patients with type 1 diabetes mellitus, 1809 (5.5%) died during follow-up over 10.4 years. The strongest predictors for death and cardiovascular outcomes were glycohemoglobin, albuminuria, duration of diabetes mellitus, systolic blood pressure, and low-density lipoprotein cholesterol. Glycohemoglobin displayed approximate to 2% higher risk for each 1-mmol/mol increase (equating to approximate to 22% per 1% glycohemoglobin difference), whereas low-density lipoprotein cholesterol was associated with 35% to 50% greater risk for each 1-mmol/L increase. Microalbuminuria or macroalbuminuria was associated with 2 to 4 times greater risk for cardiovascular complications and death. Glycohemoglobin <53 mmol/mol (7.0%), systolic blood pressure <140 mm Hg, and low-density lipoprotein cholesterol <2.5 mmol/L were associated with significantly lower risk for outcomes observed. CONCLUSIONS: Glycohemoglobin, albuminuria, duration of diabetes mellitus, systolic blood pressure, and low-density lipoprotein cholesterol appear to be the most important predictors for mortality and cardiovascular outcomes in patients with type 1 diabetes mellitus. Lower levels for glycohemoglobin, systolic blood pressure, and low-density lipoprotein cholesterol than contemporary guideline target levels appear to be associated with significantly lower risk for outcomes.

- BACKGROUND Patients with diabetes are at higher risk for death and cardiovascular outcomes than the general population. We investigated whether the excess risk of death and cardiovascular events among patients with type 2 diabetes could be reduced or eliminated. In a cohort study, we included 271,174 patients with type 2 diabetes who were registered in the Swedish National Diabetes Register and matched them with 1,355,870 controls on the basis of age, sex, and county. We assessed patients with diabetes according to age categories and according to the presence of five risk factors (elevated glycated hemoglobin level, elevated low-density lipoprotein cholesterol level, albuminuria, smoking, and elevated blood pressure). Cox regression was used to study the excess risk of outcomes (death, acute myocardial infarction, stroke, and hospitalization for heart failure) associated with smoking and the number of variables outside target ranges. We also examined the relationship between various risk factors and cardiovascular outcomes. The median follow-up among all the study participants was 5.7 years, during which 175,345 deaths occurred. Among patients with type 2 diabetes, the excess risk of outcomes decreased stepwise for each risk-factor variable within the target range. Among patients with diabetes who had all five variables within target ranges, the hazard ratio for death from any cause, as compared with controls, was 1.06 (95% confidence interval [CI], 1.00 to 1.12), the hazard ratio for acute myocardial infarction was 0.84 (95% CI, 0.75 to 0.93), and the hazard ratio for stroke was 0.95 (95% CI, 0.84 to 1.07). The risk of hospitalization for heart failure was consistently higher among patients with diabetes than among controls (hazard ratio, 1.45; 95% CI, 1.34 to 1.57). In patients with type 2 diabetes, a glycated hemoglobin level outside the target range was the strongest predictor of stroke and acute myocardial infarction; smoking was the strongest predictor of death. Patients with type 2 diabetes who had five risk- factor variables within the target ranges appeared to have little or no excess risk of death, myocardial infarction, or stroke, as compared with the general population.

Tidskriftsartikel (refereegranskat)abstract
- Rapid-acting insulin analogs (RAIs) have not been examined for long-term safety in randomized clinical trials. We performed a nationwide longitudinal cohort study among individuals with type 2 diabetes (T2DM) to address cardiovascular safety and mortality among users of lispro, aspart and glulisine insulins.We used four national registers, following patients previously not treated with RAI but with continuous use of RAIs in 2005-2014 up to 6.4 years, to examine HbA1c and weight, and the occurrence of severe hyperglycemia or hypoglycemia, renal failure, cardiovascular events or death. The treatment groups were compared using a weighted Cox proportional hazards model.We included 17,620 patients, mean age slightly higher than 60years, diabetes duration 9.9-11.7years, mean BMI 30.5kg/m(2), HbA1c around 70mmol/mol (8.6% NGSP), and 40.9-54.0% of the patients exhibiting eGFR <60ml/min/1.73m(2) in the three groups. Around 95% of the patients also used another insulin, and 24.2-24.7% had a history of cardiovascular disease (CVD). Mean HbA1c and weight levels were stable and similar. Incidence rates of death were 234.4, 284.9 and 156.7 per 1000 person-years among users of lispro, aspart, and glulisine; incidence rates of all cardiovascular events were 668.4, 622.4, and 699.5 per 1000 person-years, respectively. There were no differences in mortality, CVD, renal failure or severe hypoglycemia or hyperglycemia, although a lower mortality risk in patients on glulisine compared with aspart, and lower risk of stroke in users of glulisine was suggested. The risk of severe hyperglycemia was higher with lispro than aspart, and lower of severe hypoglycemia than aspart or glulisine among the older age group.Overall, there do not appear to be any major important differences in effects on hypoglycemia, hyperglycemia, weight or long-term safety between the three available RAIs among insulin-naive individuals with T2DM in clinical practice.

- - To compare treatment persistence in patients with type 2 diabetes mellitus initiating the glucagon-like peptide-1 receptor agonists (GLP-1 RAs) dulaglutide, exenatide once-weekly (QW), liraglutide, or lixisenatide in routine clinical practice in Sweden and assess clinical outcomes.We performed a retrospective study using data from several nationwide Swedish health registries, including the National Diabetes Register and other mandatory and population-based registries. Individual level data were collected from 17,361 patients who initiated GLP-1 RA treatment between the 23 May 2015 and the 15 Oct 2017, up to 2.5years post-index (treatment start date). Treatment persistence and modification, predictors of discontinuation, glycated hemoglobin A1c (HbA1c), and body weight were recorded. Non-persistence was defined as a treatment gap of >45days. Treatment modification included switching and augmentation. Confounding was addressed through the use of propensity scores.Treatment persistence was higher and treatment modifications were lower in patients initiating dulaglutide, compared with those on exenatide QW, liraglutide, and lixisenatide. Patients who remained on the same treatment for 1-year post-index experienced greater HbA1c reductions and a steadier decrease in body weight, compared with those who switched treatment.Our study suggests that in clinical practice in Sweden, there is a greater persistence of treatment among patients initiating dulaglutide, compared with those on exenatide QW, liraglutide, and lixisenatide. Persistence with the index GLP-1 RA was closely correlated with positive clinical outcomes and should thus be considered a critical factor of patient-centric treatment in Sweden.

- Epidemiological data indicate decreased risk for development and growth of abdominal aortic aneurysm (AAA) among patients with diabetes mellitus (DM). On the other hand, DM adds to increased cardiovascular (CV) morbidity and mortality. In a nationwide observational cohort study of patients registered in the Swedish Vascular Register and the Swedish National Diabetes Register, we evaluated potential effects of DM on total mortality, CV morbidity, and the need for reintervention after elective endovascular aneurysm repair (EVAR) for AAA. We compared 748 patients with and 2630 without DM with propensity score-adjusted analysis, during a median 4.22 years of follow-up for patients with DM, and 4.05 years for those without. In adjusted analysis, diabetic patients showed higher rates of acute myocardial infarction (AMI) during follow-up (relative risk (RR) 1.44, 95% CI 1.06–1.95; p = 0.02), but lower need for reintervention (RR 0.12, CI 0.02–0.91; p = 0.04). There were no differences in total (RR 0.88, CI 0.74–1.05; p = 0.15) or CV (RR 1.58, CI 0.87–2.86; p = 0.13) mortality, or stroke (RR 0.95, CI 0.68–1.32; p = 0.75) during follow-up. In conclusion, patients with DM had higher rates of AMI and lower need for reintervention after elective EVAR than those without DM, whereas neither total nor CV mortality differed between groups. The putative protective effects of DM towards further AAA enlargement and late sac rupture may help explain the lower need for reintervention and absence of excess mortality.
