  Aims  To study prospectively the impact of initiating insulin glargine in suboptimally controlled insulin-naive patients with Type 2 diabetes on health-related quality of life in relation to glycaemic control. Methods  Insulin-naive Dutch patients with Type 2 diabetes in suboptimal glycaemic control (HbA1c > 53 mmol/mol; 7%) on maximum dose of oral glucose-lowering medications were included from 363 primary care practices (n = 911). Patients started insulin glargine and were followed up for 6 months. At baseline (start insulin therapy), 3 and 6 months, HbA1c was measured and patients completed self-report health-related quality of life measures, including emotional well-being (World Health Organization-5 well-being index), fear of hypoglycaemia (Hypoglycaemia Fear Survey) and diabetes symptom distress (Diabetes Symptom Checklist−revised). Data were analysed using generalized estimating equations analysis. Results  HbA1c (mmol/mol; %) decreased from 69 ± 16; 8.5 ± 1.7 to 60 ± 11; 7.6±1.0 and 57 ± 11; 7.3 ± 1.0 at 3 and 6 months, respectively (P < 0.001). Pre-insulin BMI (kg/m2) was 30 ± 5.7, which remained stable at 3 months (30 ± 5.8) and increased to 31 ± 5.9 at 6 months (P = 0.004); no significant changes in self-reported symptomatic and severe hypoglycaemia were observed, while nocturnal hypoglycaemia slightly decreased. The Hypoglycaemia Fear Survey score decreased from 14.6 ± 16.2 to 12.1 ± 15.2 and 10.8 ± 14.4 at 3 and 6 months, respectively (P < 0.001). The Diabetes Symptom Checklist−revised score decreased from 15 ± 14 to 10 ± 12 and 10 ± 13 (P < 0.001), with most pronounced reductions in hyperglycaemic symptoms and fatigue. The World Health Organization-5 score increased from 57 ± 25.3 to 65 ± 21.6 at 3-month follow-up and 67 ± 21-8 at 6-month follow-up (P < 0.001). Conclusions  Results of this observational study demonstrate combined glycaemic and health-related quality of life benefits of initiating insulin glargine in patients with Type 2 diabetes in routine primary care.

Aims

Modulation of dopamine receptor D2 (DRD2) activity affects insulin secretion in both rodents and isolated pancreatic β-cells. We hypothesized that single nucleotide polymorphisms in the DRD2/ANKK1 locus may affect susceptibility to Type 2 diabetes in humans.

Methods

Four potentially functional variants in the coding region of the DRD2/ANKK1 locus (rs1079597, rs6275, rs6277, rs1800497) were genotyped and analysed for Type 2 diabetes susceptibility in up to 25 000 people (8148 with Type 2 diabetes and 17687 control subjects) from two large independent Dutch cohorts and one Danish cohort. In addition, 340 Dutch subjects underwent a 2-h hyperglycaemic clamp to investigate insulin secretion. Since sexual dimorphic associations related to DRD2 polymorphisms have been previously reported, we also performed a gender-stratified analysis.

Results

rs1800497 at the DRD2/ANKK1 locus was associated with a significantly increased risk for Type 2 diabetes in women (odds ratio 1.14 (1.06-1.23); = 4.1*10−4) but not in men (odds ratio 1.00 (95% CI 0.93-1.07); = 0.92) or the combined group. Although rs1800497 was not associated with insulin secretion, we did find another single nucleotide polymorphism in this locus, rs6275, to be associated with increased first-phase glucose-stimulated insulin secretion in women (= 5.5*10−4) but again not in men (= 0.34).

Conclusion

The present data identify DRD2/ANKK1 as a potential sex-specific Type 2 diabetes susceptibility gene.
