Pericarditis in AIDS.
A wide variety of organisms and conditions have been reported to cause pericarditis in patients that present and die with AIDS. Although pericarditis is remarkably common in patients dying of AIDS, no consistent pattern of cause emerges. Patients with AIDS are susceptible to pericarditis as a concomitant of the terminal condition, but it seldom contributes to the patient's death. Alternatively, pericarditis (as opposed to silent pericardial effusion) as a cardinal symptom in a patient's illness is likely to have an origin that can be ascribed to organisms typically associated with infectious pericarditis in those patients who have profound cellular immunodeficiency. Thus, it is important to make the diagnosis of infectious or neoplastic pericarditis in the setting of AIDS, since control of the agent has the potential of influencing the clinical course. In the absence of signs of hemodynamic compromise or inflammation, pericardial effusion may be accepted as an accompaniment of pleural effusions or ascites in the appropriate clinical context. Invasive diagnostic measures may be reserved for those cases in which pericardial disease is a prominent feature of the symptom complex or of accompanying pleural effusion. The study of epidemiology and biology of AIDS is a rapidly changing field. Explanations of the high incidence of pericardial disease in terminal disease may emerge with broad-ranging studies of the incidence of myocarditis in AIDS as well as the relative contribution to pericardial disease of agents used in the treatment of the illness.
