Fibrocalculous pancreatic diabetes (FCPD) is a secondary form of diabetes mellitus occurring primarily in tropical countries like Bangladesh and has distinct characteristics. The present study aimed to describe the demographic, clinical and biochemical characteristics of patients with FCPD. This cross-sectional study was conducted at Mymensingh Medical College Hospital, Bangladesh, from January 2019 to December 2021. All patients with FCPD (previously or newly diagnosed) admitted to the inpatient Endocrinology department of the hospital were evaluated. Out of the 15 patients, 73.3% were aged 10-29 years at diagnosis, the male: female ratio was 11:4, rural: urban ratio was 9:6, 20.0% had FCPD in the first-degree family members, 73.3% were underweight, none were overweight/obese or central obese and one of them was hypertensive. Diabetes was uncontrolled in all, with a mean HbA1c of 10.5±1.9%. All but one had low C-peptide and all required insulin to manage diabetes. Although their average (mean or median) lipid parameters were normal, 73.3% of them had dyslipidemia. Among diabetic complications, diabetic nephropathy (66.7%) and neuropathy (66.7%) were more frequent, whereas diabetic retinopathy (6.7%), ischemic heart disease (6.7%) and peripheral vascular disease (6.7%) were less frequently observed; 13.3% had a history of diabetic ketoacidosis. Malnutrition manifested as abnormal skin and hair conditions and anemia was also common in the study subjects. Patients with FCPD are usually young males from rural residences. Microvascular diabetic complications are common, but macrovascular complications and DKA can occur in FCPD.
