- OBJECTIVES: To estimate the total direct medical costs to society for patients with type 2 diabetes in Sweden and to investigate how different factors, for example diabetic late complications, affect costs. DESIGN: Cross-sectional data regarding health care utilization, clinical characteristics and quality of life, were collected at a single time-point. Data on resource use cover the 6-month period prior to this time point. SETTING: Patient recruitment and data collection were performed in nine primary care centres in three main regions in Sweden. SUBJECTS: Only patients with an age at diabetes diagnosis >/= 30 years (type 2 diabetes) were included (n = 777). RESULTS: The total annual direct medical costs for the Swedish diabetes type 2 population were estimated at about 7 billion SEK (Swedish Kronor) in 1998 prices, which is about 6% of the total health care expenditures and more than four times higher than the former Swedish estimate obtained when using diabetes as main diagnosis for calculating costs. The annual per patient cost was about 25 000 SEK. The largest share of this cost was hospital inpatient care. Costs increased with diabetes duration and were higher for patients treated with insulin compared to those treated with oral hypoglycaemic drugs or with life style modification only. Patients with both macro- and microvascular complications had more than three times higher costs compared with patients without such complications. CONCLUSIONS: Type 2 diabetes is a serious and expensive disease and the key to reducing costs seems to be intensive management and control in order to prevent and delay the associated late complications.

- Differences have been observed in the relationship between leptin and metabolic perturbations in glucose homeostasis. Because no information is available from indigenous African populations with diabetes, the purpose of this study was to investigate the possible associations between leptin and different clinical and biochemical characteristics of a large group of subjects with type 2 diabetes mellitus in Sudan. A total of 104 (45 men and 59 women) consecutive type 2 diabetes patients and 75 control subjects (34 men and 41 women) were studied. The body mass index (BMI), blood glucose, serum insulin, and proinsulin were measured and related to serum leptin concentrations. Leptin was higher in females than in males and correlated significantly to BMI. The main novel finding was that serum leptin was significantly lower in diabetic subjects compared with controls in both females (P =.0001) and males (P =.019), although BMI did not differ between diabetic and nondiabetic subjects. Diabetic subjects treated with sulphonylurea (n = 81) had lower BMI than those treated with diet alone or other hypoglycemic drugs (n = 23) (P =.0017), but there was no difference in leptin levels between the 2 groups after adjustment for BMI (P =.87). In diabetic subjects, serum leptin correlated positively with the homeostatic assessment (HOMA) of both beta-cell function (P =.018) and insulin resistance (P =.038), whereas in control subjects, leptin correlated with insulin resistance (P =.0016), but not with beta-cell function. Diabetic subjects had higher proinsulin levels (P =.0031) and higher proinsulin to insulin ratio (P =.0003) than nondiabetic subjects. In univariate analysis, proinsulin showed a weak correlation to leptin (P =.049). In conclusion, we show in a large cohort of Sudanese subjects with type 2 diabetes that circulating leptin levels are lower in diabetic subjectss than in controls of similar age and BMI. The lower serum leptin in diabetic subjects may be a consequence of differences in fat distribution.
