The patient, a 30-year-old homosexual man, complained of unexplained weight loss, chronic

right-sided pneumonitis. The following studies were performed:

Diagnostic Analysis

The detection of Pneumocystis jiroveci pneumonia (PCP) supports the diagnosis of AIDS.

PCP is an opportunistic infection occurring only in immunocompromised patients and is the

most common infection in persons with AIDS. The patient’s diarrhea was caused by

Cryptosporidium muris, an enteric pathogen, which occurs frequently with AIDS and can be

identified on a stool culture. The AIDS serology tests made the diagnoses. His viral load is

significant, and his prognosis is poor.

The patient was hospitalized for a short time for treatment of PCP. Several months after he

was discharged, he developed Kaposi sarcoma. He developed psychoneurologic problems

eventually and died 18 months after the AIDS diagnosis.
