Abstract

In this article, we report a male patient infected with HIV presenting with cryptococcal meningitis, pneumonia, and bloodstream infection, along with intestinal obstruction and gastrointestinal bleeding. Cerebrospinal fluid and bloodstream analyses revealed the presence of Cryptococcus neoformans complex. The isolated strain was sequenced and was found to belong to Cryptococcus neoformans var. grubii with a new sequence type (ST). The strain led to fatal multisystemic cryptococcosis in a short time, and the patient died due to hemorrhagic shock because of gastrointestinal bleeding despite emergency rescue efforts. There are few reports about cryptococcosis in HIV-infected patients caused by new ST isolates. We report a new Cryptococcus neoformans ST (ST702) isolate causing infection in an HIV-infected patient, which merits further study and clinical attention.
