Fournier's Gangrene in an HIV-Positive Patient on Empagliflozin for the Treatment of Diabetes Mellitus

Fournier's gangrene is a severe polymicrobial infection that results in necrosis of the perineal and genital fasciae with rapid progression. This case report describes a 55-year-old male with a past medical history of HIV, type 2 diabetes, and hypertension who was diagnosed with Fournier's gangrene after the administration of empagliflozin (Jardiance). The patient presented with a worsening ulcer of the right groin and was diagnosed with Fournier's gangrene based on clinical and radiographic findings. He underwent surgical debridement of the wound. The patient was treated with empiric vancomycin, piperacillin-tazobactam, and clindamycin. Wound cultures grew Streptococcus anginosus and Staphylococcus epidermidis. His antibiotic regimen was simplified to ampicillin-sulbactam. The patient required reconstructive surgery for wound closure after debridement. He received an additional 18 days of augmentin therapy with the resolution of the infectious process. At the time of Fournier's gangrene onset, the patient's last HbA1C level was 8.2%, despite treatment with glipizide and empagliflozin. This case suggests an association between empagliflozin and Fournier's gangrene in the setting of active HIV infection.
