Etiology and outcome of childhood and adolescent diabetes mellitus in North India.
The etiology of childhood onset diabetes mellitus (DM) varies between regions and races, and its long-term outcome is affected by social and economic factors. There are scant data on the etiology of childhood DM and outcome of multidisciplinary team management from developing countries. We retrospectively analyzed case records of 160 predominantly middle socio-economic group patients with onset of DM < or =18 years of age for etiology and features at presentation. In addition, we prospectively studied acute and chronic complications and metabolic control in a subset of 67 patients. Type 1 DM comprised 81%, type 2 DM 8%, and fibrocalculous pancreatic DM 9% of patients. Mean HbA1c was 8.0+/-1.5%. Retinopathy was present in 22% and nephropathy in 18% of those with DM duration > or =5 years (mean age 21.2+/-6.8 years, mean duration 10.2+/-4.6 years). The frequency of ketoacidosis and severe hypoglycemia was 5.0 and 3.3 episodes per 100 patient years. Mortality was 7% over 823 person years of follow up. We conclude that fairly good metabolic control is achievable in a middle socio-economic population in India, with the assistance of a diabetes education program. The frequency of microvascular complications is comparable to that in the literature. However, mortality remains unacceptably high.
