Use of a Sodium-Glucose Cotransporter 2 Inhibitor, Empagliflozin, in a Patient with Rabson-Mendenhall Syndrome.

Introduction: Among the insulin resistance syndromes that lead to diabetes mellitus in young people, Rabson-Mendenhall syndrome (RMS; OMIM # 262190) is an autosomal recessive inherited disease caused by an insulin receptor mutation (INSR; 147,670). Due to the rarity and complexity of the disease, we have few therapeutic alternatives other than insulin with clinical studies with robust evidence. Some reports suggest the adjunct use of metreleptin, metformin, and pioglitazone with improved glycemic control, however, with results still unsatisfactory for the desirable glycemic targets for this age group.
