[Hodgkin's disease in patients with infection caused by the human immunodeficiency virus. Study of 9 cases].

Nine young males with Hodgkin's disease (HD) and antibodies against the human immunodeficiency virus were evaluated. They had been diagnosed since 1984 in three Madrid hospitals: Hospital 12 de Octubre, Hospital Ramón y Cajal, and Clínica Puerta de Hierro. Eight patients were intravenous heroin abusers and one was homosexual. In 8 patients (88.8%) HD presented in advanced stages (III and IV), and in 5 cases (55.5%) the histology corresponded to mixed cell type. Four patients (44.4%) developed opportunistic infections. In the immunological study a reduction of CD4+ lymphocytes below 0.4 X 10(3)/l was found in 5 of 7 patients (71.4%), and an inversion of CD4+/CD8+ ratio in 6 of 7 patients (85.7%). The response to therapy was poor. Five patients died (55.5%). In 4, the direct cause of death was an opportunistic infection. The reasons why we think that HD in patients with HIV infections should be considered as indicating acquired immunodeficiency syndrome are discussed.

[Endocarditis due to Pseudomonas aeruginosa (author's transl)].

A case of pseudomonas endocarditis of biliary origin with impairment of the mitral and tricuspid heart valves is reported. Former history of the patient did not reveal narcotic addiction or previous open-heart surgery. Osteomyelitis is an uncommon complication of pseudomonas endocarditis. Echocardiography was a useful diagnostic method in the present case, showing the vegetation on the tricuspid valve. The poor prognosis of cases with left valvular heart disease which are resistant to medical treatment is emphasized. Differential count of the colonies did not localize the affected heart valve in this case.
