Abstract:
A 14 year male adolescent born of 2nd degree consanguineous marriage presented with asymptomatic proteinuria and severe anemia. He had leucopenia, anisopoikilocytosis, megaloblastic erythropoiesis, megakaryocytes with low serum B12 level. His younger sibling was similarly affected. This combination suggested Imerslund-Grasbeck syndrome. The hemoglobin levels improved with injection of vitamin B12 but proteinuria persisted. During follow-up, he developed ketoacidosis due to insulin dependent diabetes mellitus. This rare combination has not been reported in the Indian literature.

Diabetes Mellitus: Overview and Type I Subtype
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
