Persistent Candidemia in the Postpartum Period: A Case of Uterocutaneous Fistula and the Role of Dual Antifungal Therapy

Candidemia, the systemic spread of Candida spp, is a significant concern in intensive care units and among immunocompromised patients. This case report details a young postpartum female who developed persistent candidemia following a lower-segment cesarean section. Postoperatively, she experienced a high-grade fever, respiratory distress, and disorientation, initially managed with broad-spectrum antibiotics and later with antifungal therapy. Blood cultures confirmed Candida glabrata, and imaging revealed a likely útero-cutaneous fistula as the infection source. Despite initial monotherapy, the patient showed no improvement, prompting the addition of a second antifungal agent. The dual regimen of caspofungin and voriconazole led to clinical improvement, and subsequent blood cultures were sterile. The patient was discharged on oral fluconazole. This case underscores the complexities of managing persistent candidemia, particularly in the postpartum period, and highlights the potential benefits of dual-antifungal therapy in refractory cases. Comprehensive imaging and a multidisciplinary approach were crucial in identifying and managing the uncommon source of infection. This report contributes to the limited literature on postpartum candidemia and emphasizes the need for thorough evaluation and tailored treatment strategies. Further research is needed to establish clear guidelines for using combination antifungal therapy in persistent candidemia and to explore the management of complex cases involving uncommon sources of infection.
