Histopathological changes of pancreas in patients with fibrocalculous pancreatopathy.

A total of 20 pancreatic biopsy samples taken from Fibrocalculous Pancreatopathy previously known as Fibro Calculus Pancreatic Diabetes (FCPD) patients, a variant of Malnutrition Related Diabetes Mellitus (MRDM) or under 30 young diabetes attending hepatobiliary, surgical and out patient department of Bangladesh Diabetes, Endocrine and Metabolic (BIRDEM) hospital were processed for light microscopic examination. Four samples were subjected to Immunohistochemistry (IHC) staining using antibodies to T cell marker (CD3), B cell marker (CD20), anti apoptotic markers (bcl-2) and tumour suppressor gene marker p53. Light microscopic findings and IHC indicate an immune mediated injury of pancreatic tissue and increased evidence of apoptosis which possibly results in the development of diabetes in these patients.
