A 27-Year-Old with Disseminated Histoplasmosis
Disseminated histoplasmosis in HIV-infected persons is a potentially life-threatening infection. Clinical manifestations are often non-specific. Diagnostic testing often involves using a combination of tests, including antigen tests and culture. Preferred initial treatment of progressive disseminated infection consists of liposomal amphotericin B (AmBisome), followed by maintenance therapy with oral itraconazole (Sporanox).

A 43-Year-Old with New Visual Symptoms
Cytomegalovirus retinitis remains an important clinical problem with patients with advance immunosuppression. Symptoms of cytomegalovirus retinitis usually include one or more of the four “F’s”: floaters, flashes, field deficits, or failing vision. Oral valganciclovir (Valcyte), with or without a ganciclovir intraocular implant, is generally recommended for initial therapy.

African Americans with HIV: Epidemiology and Risk Factors
The HIV epidemic has disproportionately affected African Americans and in recent years more new diagnoses of HIV (with or without AIDS) involve African Americans than any other racial/ethnic population. This case includes a review of the epidemiology and factors related to the explosion of the HIV epidemic in African Americans.

Protease Inhibitor-Associated Hyperbilirubinemia
Isolated unconjugated hyperbilirubinemia is a known adverse effect that can develop while taking atazanavir. This case includes a review of the natural history, mechanism, genetic predisposition, and management of protease-inhibitor associated hyperbilirubinemia.

Homelessness and HIV
The HIV epidemic in the United States involves a substantial number of marginally housed and homeless individuals. The optimal management of homeless HIV-infected persons requires an in-depth understanding of many of the unique aspects of clinical care for this patient population.

A 37-Year-Old Migrant Worker with Diarrhea
In evaluating this AIDS patient with severe diarrhea, challenge your skills in identifying gastrointestinal parasitic pathogens as seen on a modified acid-fast smear of a stool sample. Differentiating these pathogens is paramount for optimal management.
