Cryptosporidium parvum-associated sclerosing cholangitis in a liver transplant patient.

Cryptosporidium parvum causes severe long-standing diarrhea in immunocompromised patients. Sclerosing cholangitis caused by C. parvum is a rare complication in transplant recipients. We report herein the presentation of Cryptosporidium-associated cholangitis in an adult liver transplant patient diagnosed by liver biopsy. The patient improved on treatment with azithromycin and paromomycin.

Cerebral phaeohyphomycosis due to a novel species: report of a case and review of the literature.

Cerebral phaeohyphomycosis is a rare disease caused by dematiaceous (darkly pigmented) fungi. Cladophialophora species are highly neurotropic, and Cladophialophora bantiana (synonym=Xylohypha bantiana or C. trichoides) is the most commonly identified agent. Most reported cases of cerebral phaeohyphomycosis have occurred in immunocompetent patients; however, some case reports and experimental data have suggested that cellular immune deficiency is a risk factor. We report a case of pulmonary and cerebral phaeohyphomycosis in a cardiac transplant patient due to a newly identified species of Cladophialophora. Optimal management includes both antifungal therapy and surgery.

Primary Vibrio vulnificus bacteremia in a liver transplant recipient after ingestion of raw oysters: caveat emptor.

Vibrio vulnificus is responsible for severe infections in chronically ill patients. Organ transplant recipients are also at risk for severe infections due to V vulnificus. We report here the first case of V. vulnificus primary bacteremia due to raw shellfish consumption in a liver transplant recipient. All transplant patients should be cautioned against consuming uncooked seafood and warned about the risk of severe Vibrio infections from seemingly innocuous wounds acquired in a salt water environment.
