Parasitic infections & ectoparasitic infestations.

The epidemiology, pathogenesis, clinical manifestations, histopathology, and differential diagnosis of parasitic infections and ectoparasitic infestations, especially scabies, in HIV-positive patients are examined. Treatment options for scabies include lindane cream or lotion or five percent permethrin cream. Precipitated sulfur in petrolatum may also be effective. Post-treatment sensitivity can be treated with corticosteroids. Various antifungal agents are used to treat demodicidosis, pneumocystosis, strongyloidiasis, amebiasis, and leishmaniasis, although different drugs may be required to treat these infections in immunocompromised hosts. Suggestions are provided to treat prurititis which accompanies these infections.
