A complicated pregnancy in a patient with lipodystrophic diabetes attributable to a peroxisome proliferator-activated receptor gamma (PPARG) mutation

Diabet. Med. 29, e398-e401 (2012) ABSTRACT: Background We describe an unplanned pregnancy in a 19-year-old with lipodystrophic diabetes caused by a mutation in the peroxisome proliferator-activated receptor gamma (PPARG) gene. The pregnancy was complicated by poor compliance with treatment, severe hypertriglyceridaemia and pancreatitis. Case report The patient presented at 6?weeks' gestation with an HbA(1c) of 140?mmol/mol (15%), cholesterol 8.1?mmol/l and triglycerides 20.1?mmol/l. She wished to continue the pregnancy so lipid-lowering therapy was discontinued. She was severely insulin resistant and poorly compliant with diet and medication. A continuous subcutaneous insulin infusion was required for efficient delivery of large doses of basal insulin, alongside injected mealtime boluses, (up to 300?units insulin per day). At 17?weeks' gestation she developed acute pancreatitis secondary to hypertriglyceridaemia (triglycerides >?100?mmol/l) and required plasmapheresis. Lipid-lowering therapy was reinstated in the third trimester and plasmapheresis was required repeatedly to maintain triglycerides
