RESUMO
BACKGROUND AND PURPOSE: To assess long-term treatment effectiveness of disease-modifying therapy (DMT) initiated early in disease course versus later treatment start. METHODS: We included all Danish patients with multiple sclerosis (MS) treated with DMT through two nationwide population-based MS registries. Patients were categorized as early treated if treatment started within 2 years after the first MS symptom (n = 2316) and later treated if treatment started between 2 and 8 years after clinical onset (n = 1479). We compared time from treatment start to progression to an Expanded Disability Status Scale (EDSS) score of 6 and mortality between cohorts as hazard ratio (HR) using a Cox proportional hazards model with adjustment for stabilized inverse probability of treatment weights. Several sensitivity analyses were conducted. RESULTS: The median follow-up time of 3795 patients was 7.0 (range 0.6-19.5) years for the EDSS score of 6 outcome and 10.4 (range 1.2-20.1) years for the mortality outcome. Patients with later treatment start showed a 42% increased hazard rate of reaching an EDSS score of 6 compared with the early-treated patients [HR, 1.42; 95% confidence interval (CI), 1.18-1.70; P < 0.001]. When stratified by sex, the increased hazard among later-treated women persisted (HR, 1.53; 95% CI, 1.22-1.93; P < 0.001), whereas the HR was lower in men (1.25; 95% CI, 0.93-1.69; P = 0.15). Mortality was increased by 38% in later starters (HR, 1.38; 95% CI, 0.96-1.99; P = 0.08). CONCLUSIONS: Patients who started treatment with DMT later reached an EDSS score of 6 more quickly compared with patients who started early and the delay showed a tendency to shorten time to death. Our results support the use of early treatment.

AIMS: To examine the usage and real-life effectiveness of intensification therapies in people with Type 2 diabetes treated with basal insulin. METHODS: We used population-based healthcare databases in Denmark during 2000-2012 to identify all individuals with a first basal insulin prescription (with or without oral drugs), and evaluated subsequent intensification therapy with bolus insulin, premixed insulin or glucagon-like peptide-1 (GLP-1) receptor agonists. Poisson regression was used to compute the adjusted relative risks of reaching glycaemic control targets. RESULTS: We included 7034 initiators of basal insulin (median age 64 years, diabetes duration 5.3 years, 84% with oral co-medication and median (interquartile range) pre-insulin HbA1c level 77 (65-92) mmol/mol [9.2% (8.1-10.6%)]. Of these, 3076 (43.7%) received intensification therapy after a median of 11 months: 58.5% with premixed insulin, 29.0% with bolus insulin, 10.6% with GLP-1 receptor agonists, and 1.9% with more than one add-on. Overall, 22% had attained an HbA1c level of < 53 mmol/mol (< 7%) by 3-6 months after intensification, while 38% attained an HbA1c < 58 mmol/mol (< 7.5%). Compared with premixed insulin intensification, attainment of HbA1c < 53 and < 58 mmol/mol was similar with bolus insulin add-on [adjusted relative risk 1.03 (95% CI 0.86-1.24) and 1.02 (95% CI 0.91-1.15), and higher for GLP-1 receptor agonist add-on [adjusted relative risk 1.56 (95% CI 1.27-1.92) and 1.27 (1.10-1.47)]. CONCLUSIONS: Among people with Type 2 diabetes, 22 and 38% reached a target HbA1c < 53 mmol/mol (< 7%) or < 58 mmol/mol (< 7.5%), respectively, after intensification of their basal insulin therapy. Compared with premixed insulin, target attainment was similar with bolus insulin and higher with GLP-1 receptor agonists.

UNLABELLED: Perceived stress is associated with several adverse health outcomes; however, little is known about the impact of stress on fracture risk. In this population-based cohort study, persons with high perceived stress have an increased 5-year risk of any osteoporotic fracture, in particular hip fracture. INTRODUCTION: We conducted a population-based cohort study in Denmark to examine the association between perceived stress and risk of subsequent osteoporotic fracture. METHODS: A 2006 population-based health survey in the Central Danish Region (with 1.25 million inhabitants) was used to identify 7943 persons who were 55 years or older on the survey date and completed the Perceived Stress Scale. Individuals were categorized into two groups: high level of stress and low level of stress (including no stress). We obtained information on all osteoporotic fractures through linkage to the Danish National Registry of Patients. We used Cox regression to compute hazard ratios (HRs) with 95 % confidence interval (CI) adjusted for a number of lifestyle factors, socioeconomic data, perceived general health, and prescription history, comparing high- and low-stress persons. RESULTS: A total of 1799 persons (22.6 %) reported high level of perceived stress, whereas 6144 (77.4 %) reported low level or no stress. The 5-year risk of any osteoporotic fracture was 7.4 and 5.4 % in persons with high and low perceived stress, respectively, corresponding to adjusted HR of 1.37 (CI 1.00-1.89). The adjusted HR for hip fracture within 5 years associated with high perceived stress was 1.68 (CI 1.04-2.72). The associations weakened with increasing follow-up time. CONCLUSIONS: Persons with high perceived stress have an increased risk of any osteoporotic fracture, in particular risk of hip fracture within 5 years of stress assessment even after adjusting for differences in lifestyle, comorbidities, osteoporosis presence, medication use, and socioeconomic status at the time of stress level evaluation. The association attenuated after longer follow-up time.

AIMS: To identify individual predictors of early glycaemic control in people with Type 2 diabetes mellitus after initiation of first glucose-lowering drug treatment in everyday clinical practice. METHODS: Using medical registries, we identified a population-based cohort of people with a first-time glucose-lowering drug prescription in Northern Denmark in the period 2000-2012. We used Poisson regression analysis to examine patient-level predictors of success in reaching early glycaemic control [HbA1c target of < 53 mmol/mol (7%)] < 6 months after treatment start. RESULTS: Among the 38 418 people (median age 63 years), 27 545 (72%) achieved early glycaemic control. The strongest predictor of achieving early control was pre-treatment HbA1c level; compared with a pre-treatment HbA1c level of ≤ 58 mmol/mol (7.5%), the adjusted relative risks of attaining early control were 0.63 (95% CI 0.61-0.64) for baseline HbA1c levels of > 58 and ≤ 75 mmol/mol (> 7.5 and ≤ 9%), and 0.58 (95% CI 0.57-0.59) for a baseline HbA1c level of > 9% (> 75 mmol/mol). All other examined predictors were only weakly associated with the chance of achieving early control. After adjustment, the only characteristics that remained independently associated with early control (in addition to high baseline HbA1c ) were being widowed (adjusted relative risk 0.95; 95% CI 0.93-0.97) and having a high Charlson comorbidity index score (score ≥ 3; adjusted relative risk 0.94; 95% CI 0.90-0.97). CONCLUSIONS: In a real-world clinical setting, people with Type 2 diabetes mellitus initiating glucose-lowering medication had a similar likelihood of achieving glycaemic control, regardless of sex, age, comorbidities and other individual factors; the only strong and potentially modifiable predictor was HbA1c before therapy start.

AIM: To examine real-life time trends in early glycaemic control in patients with type 2 diabetes between 2000 and 2012. METHODS: We used population-based medical databases to ascertain the association between achievement of glycaemic control with initial glucose-lowering treatment in patients with incident type 2 diabetes in Northern Denmark. Success in reaching glycated haemoglobin (HbA1c) goals within 3-6 months was examined using regression analysis. RESULTS: Of 38 418 patients, 91% started with oral glucose-lowering drugs in monotherapy. Metformin initiation increased from 32% in 2000-2003 to 90% of all patients in 2010-2012. Pretreatment (interquartile range) HbA1c levels decreased from 8.9 (7.6-10.7)% in 2000-2003 to 7.0 (6.5-8.1)% in 2010-2012. More patients achieved an HbA1c target of <7% (<53 mmol/mol) in 2010-2012 than in 2000-2003 [80 vs 60%, adjusted relative risk (aRR) 1.10, 95% confidence interval (CI) 1.08-1.13], and more achieved an HbA1c target of <6.5% [(<48 mmol/mol) 53 vs 37%, aRR 1.07 95% CI 1.03-1.11)], with similar success rates observed among patients aged <65 years without comorbidities. Achieved HbA1c levels were similar for different initiation therapies, with reductions of 0.8% (from 7.3 to 6.5%) on metformin, 1.5% (from 8.1 to 6.6%) on sulphonylurea, 4.0% (from 10.4 to 6.4%) on non-insulin combination therapies, and 3.8% (from 10.3 to 6.5%) on insulin monotherapy. CONCLUSIONS: Pretreatment HbA1c levels in patients with incident type 2 diabetes have decreased substantially, which is probably related to earlier detection and treatment in accordance with changing guidelines. Achievement of glycaemic control has improved, but 20% of patients still do not attain an HbA1c level of <7% within the first 6 months of initial treatment.
