[A case report of Listeria monocytogenes infection in a patient with AIDS. Efficacy of treatment with cotrimoxazole associated with rHuG-CSF (filgrastim)].

Listeriosis is an emerging opportunistic infection in the immunocompromised host. A case of sepsis due to Listeria monocytogenes in a patient with advanced HIV infection and severe neutropenia, treated for an underlying non-Hodgkin's lymphoma, is described. Therapy with cotrimoxazole associated with rHuG-CSF (filgrastim) led to a rapidly favourable clinical and microbiological outcome, and to the correction of concurrent neutropenia. The case report is discussed according to a literature review of all cases of listeriosis reported until now in the setting of HIV infection and AIDS. In particular, the role of both cotrimoxazole and rHuG-CSF adjunct in the treatment of listeriosis in the immunocompromised patient is focused.
