Case Report: Successful Treatment Of Pulmonary Talaromyces Marneffei Infection With Posaconazole In A Renal Transplant Recipient

Talaromyces marneffei (T. marneffei), formerly Penicillium marneffei, is a dimorphic fungus prevalent in Southeast Asia that can cause severe systemic infection, especially in immunocompromised patients. There are few reports about the use of posaconazole in T. marneffei infection. Here, we present a case of pulmonary T. marneffei infection in a renal transplant recipient. The patient responded rapidly to oral posaconazole administration but experienced serum creatinine fluctuation because of the interaction between posaconazole and immunosuppressants. Seven months after adjusting the dose of immunosuppressants, the patient recovered completely. Posaconazole is a potentially promising therapy for T. marneffei infection, but it should be administered under close monitoring.
