The Incidence of Hypoglycemia among Insulin-Treated Patients with Type 1 or Type 2 Diabetes: Bangladeshi Cohort of International Operations-Hypoglycemia Assessment Tool Study.

OBJECTIVES: The objective of this study was to assess the incidence of hypoglycemia in patients with type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM) in Bangladeshi cohort of the International Operations-Hypoglycemia Assessment Tool study. MATERIALS AND METHODS: Patients diagnosed with either T1DM or T2DM, aged ≥18 years, treated with insulin (any regimen) for >12 months, and completed self-assessment questionnaires (SAQs) to record demography, treatment information, and hypoglycemia during the 6-month retrospective and 4-week prospective periods (a total of 7 months) were enrolled in the study. RESULTS: A total of 1179 patients were enrolled and completed the SAQ1 (T1DM, n = 25; T2DM, n = 1154). Almost all patients (T1DM: 100.0% [95% confidence interval (CI): 86.3%, 100.0%] and T2DM: 97.0% [95% CI: 95.9%, 97.9%]) experienced at least 1 hypoglycemic event prospectively. The estimated rates of any and severe hypoglycemia were 26.6 (95% CI: 19.8, 35.0) and 14.1 (95% CI: 9.3, 20.4) events per patient-per year (PPY), respectively, for patients with T1DM and 18.3 (95% CI: 17.4, 19.2) and 12.1 (95% CI: 11.4, 12.9) events PPY, respectively, for patients with T2DM during the prospective period. At baseline, mean glycated hemoglobin (HbA1c) (±standard deviation) was 8.1 (±1.8%) for T1DM and 8.8 (±1.8%) for T2DM. Hypoglycemic rate was independent of HbA1c levels and types of insulin. CONCLUSIONS: This is the first patient dataset of self-reported hypoglycemia in Bangladesh; results confirm that hypoglycemia is underreported.

Cognitive impairment in elderly, non-insulin dependent diabetic men in Bangladesh.

This was a case-comparison study to determine whether there was any association between non-insulin dependent diabetes mellitus (NIDDM) and cognitive impairment in subjects over the age of 65 years. Forty-eight non-insulin dependent diabetic males were compared with eighteen non-diabetic age & sex-matched controls. There was significantly higher cognitive impairment in the diabetic group compared to the control group when cognitive function was tested using the Mini-Mental State Examination (MMSE). However, after adjustment for confounding variables such as hypertension and cerebrovascular diseases there was no significant association between NIDDM per se and cognitive impairment. Other risk factors of cognitive impairment may be investigated.
