The purpose of the study was to assess the prevalence and the type of cardiac abnormalities in patients with HIV infection. Echocardiographic examination (M-mode, two-dimensional and Doppler) was performed in 51 patients (40 male, 11 female), whose mean age was 29 +/- 10 years; 48 of them (94%) were intravenous drug addicts, 3 (6%) homosexuals. Diagnosis was AIDS in 19 (37%) patients, AIDS related complex in 19 (37%) and asymptomatic infection in 13 (26%). Echocardiography was normal in 13 subjects. Pericardial effusion was found in 19 patients (in 8 of them, this was the only cardiac abnormality). Valve vegetations were found in 16 patients (3 of them had pericardial effusion, 5 had ventricular dilatation or wall motion abnormalities, 1 had both pericardial and myocardial impairment). Myocardial dysfunction was found in 18 patients: 11 had left ventricular dilatation (5 with wall hypokinesia), 1 had right ventricular enlargement, 1 had biventricular dilatation and 5 had only wall motion abnormalities (diffuse or localized). During the follow-up 9 patients died: 8 had AIDS, 1 was asymptomatic. Eight subjects died during hospitalization (none because of cardiac causes) and one at home for sudden unexplained death. Echocardiography had displayed myocardial dysfunction in 6 of them, thickened pericardium in 1 and was normal in 2. Pathologic examination (performed in 8 subjects) showed cardiac enlargement in 3 subjects, thickened pericardium in 2 and valve vegetation in 1. One subject had histopathologic diagnosis of myocarditis and 7 had non specific histologic abnormalities. The study shows a cardiac involvement in 75% of HIV infected patients: 35% had myocardial dysfunction, 37% pericardial disease, 31% infective endocarditis.(ABSTRACT TRUNCATED AT 250 WORDS)

Cardiac abnormalities are frequently reported in patients with acquired immunodeficiency syndrome (AIDS). Much less is known about the true prevalence of cardiac involvement in patients with human immunodeficiency virus (HIV) infection. We prospectively examined 138 consecutive patients with HIV infection including 41 with AIDS, 49 with AIDS-related complex (ARC), 32 with chronic lymphoadenopathy syndrome (LAS) and 16 with asymptomatic HIV infection. Sixty-one patients had opportunistic infection. The prevalence of cardiac involvement progressively increased from patients with HIV infections or LAS (4%) to ARC (14%) to AIDS (37%). "Major" echocardiographic abnormalities (dilated cardiomyopathy and/or infective endocarditis and/or severe pericardial effusion) were identified in 3 patients (2%), "minor" abnormalities (mild pericardial effusion, hypokinesis of the interventricular septum, mild dilatation of the left ventricle in 21 (15%). Electrocardiographic abnormalities unassociated with echo abnormalities or clinical problems were seen in other 11 patients. End diastolic left ventricular dimension (normalized for body surface area) was higher among AIDS respect to pre-AIDS patients (30.1 +/- 7.1 vs 27.6 +/- 7.5; p less than 0.01) and among patients with respect to patients without opportunistic infections (29.5 +/- 6.5 vs 27.5 +/- 2.4; p less than 0.05). Left ventricular shortening fraction was lower in the subgroup with and absolute CD4 lymphocyte count less than 100/mm3 (31 +/- 7 vs 34 +/- 5; p less than 0.055). In conclusion, in a large, unselected group of patients with HIV infection, echocardiogram discloses cardiac abnormalities in 17% of the cases; their clinical relevance is generally low but in selected patients cardiac tamponade and/or dilated cardiomyopathy (secondary to viral myocarditis) may cause death.(ABSTRACT TRUNCATED AT 250 WORDS)

Right-sided staphylococcal endocarditis has been described in drug-addict, but not in association with an Acquired Immunodeficiency Syndrome. A case of a 26 years old drug-addict woman with AIDS related complex is reported. Antibiotic therapy, produced a favourable evolution on the illness. This case support the usefulness of two-dimensional echocardiography for detecting one of the possible complications associated with AIDS.

Fifty cases of Hodgkin's disease in intravenous drug users (IVDU) have been collected by the Italian Cooperative Group on AIDS-Related Tumors (G.I.C.A.T.). Ninety-two per cent of the patients were males; the median age was 26 years. Persistent generalized lymphadenopathy (PGL) at onset was present in 54% of patients, AIDS in 9%, ARC in 9% while 28% were simply HIV-positive. The initial median absolute number of CD4 lymphocytes was 264/mmc. Opportunistic infections were diagnosed in 20% of patients. In most patients the histological pattern was that of mixed cellularity and lymphocytic depletion (76%). In almost half the initial symptom was a persistent lymph node enlargement due to PGL. In the majority of patients (58%) only a clinical staging and bone marrow biopsy could be performed due to the presence of opportunistic infections, rapid disease progression or refusal of pathologic staging procedures. One patient presented with a Waldeyer's ring involvement, but no other unusual presentations were observed. After MOPP alternated or followed by ABVD or MOPP alone, 15/29 CR (52%) and 14/29 PR (48%) were observed. The median duration of CR was 14 months, while the median survival of CR has not been reached; the median survival of patients treated with chemotherapy with CD4 values at presentation {geq}400/mmc was significantly superior to that in those with CD4 < 400/mmc. The overall median survival was 16 months. Twenty-eight per cent of patients receiving chemotherapy + radiotherapy developed opportunistic as well as non-opportunistic infections (21%). Lethal hepatic toxicity was observed in 2 patients. In conclusion, Hodgkin's disease in IVDU was not found to be associated with unusual presentations, as previously reported for homosexuals. Complete remissions could be achieved in over 50% of patients, but in IVDU non-opportunistic infections in addition to opportunistic infections may also limit treatment administration. The presence of parenchymal functional impairment due to drug abuse, or drug abuse-related infections, such as pneumonia, endocarditis and hepatitis, should lead to the choice of antitumour agents with no or only minor potential liver, lung and cardiac toxicity.
