Immune Reconstitution Inflammatory Syndrome in a Patient With Cutaneous Leishmaniasis and HIV: A Diagnostic Challenge for Clinicians Caring for a Migrant Population in the United States

Year: 2024

Type: article

Abstract: Migration routes determine exposure to endemic infections. We present a case of complex cutaneous leishmaniasis in a man with HIV infection who migrated to the United States from Haiti, where Leishmania is uncommon, acquiring leishmaniasis while on his journey via South America and Central America. His presentation included hyperpigmented, nonulcerated plaques and nodules on his extremities, chest, back, face, palms, and soles; initially he had no mucosal lesions. Infection with Leishmania panamensis was confirmed via polymerase chain reaction. He was prescribed bictegravir/tenofovir alafenamide/emtricitabine with rapid suppression of HIV and liposomal amphotericin B for diffuse cutaneous leishmaniasis with a limited initial response. He subsequently developed mucosal lesions in the setting of immune reconstitution and was retreated with amphotericin dosed for mucocutaneous disease. A thorough migration history was critical to diagnosis. This case highlights the different presentations of leishmaniasis in people with HIV and the elevated risk for treatment failure.
