[Intolerance to trimethoprim-sulfamethoxazole in Pneumocystis carinii pneumonia in AIDS. Search for predictive factors].

The treatment and the prevention of Pneumocystis carinii pneumonia (PCP) is based on trimethoprim-sulfamethoxazole. However, hypersensitivity reactions occur often in HIV-infected patients. In this study, clinical and biological parameters of 27 PCP-patients treated by this drug association were analyzed. We divided the drug reactions into two groups according to the severity. A drug reaction occurred in 59.2% of the patients and was note as a mild reaction in 18.5% of the cases and as a severe reaction in 40.7%. An initial high eosinophil count was noted in patients who may present future drug reaction. This difference was more significant in patients who may present severe drug reaction. No other clinical or biological factors were predictive of hypersensitivity. The immune status of HIV-disease, drug therapy, and drug mechanisms were discussed.

[Paraneoplastic edema syndromes in acute myelomonocytic leukemia: role of TNF-alpha and IL-6?].

We report the case of a 56 year-old man in remission of a Hodgkin's disease who had an acute myelomonocytic leukemia with major edemas. Chemotherapy temporarily allowed a concomitant regression of edemas, hyperleukocytosis and tumor necrosis factor and interleukin-6 levels which were initially elevated. We discuss the role of these two cytokines in endothelium permeability disorders.

[Syndrome of hemophagocytosis associated with infections].

Infection-related hemophagocytic syndrome was originally described in viral processes by Risdall in 1979. Recent reports have suggested associations of this syndrome with bacterial, parasitic and fungal infections. It occurs generally in immunosuppressed patients. The clinical and biological manifestations are not specific. The diagnosis is based on morphologic examination of the bone marrow showing a benign proliferation of histiocytes with hemophagocytosis. Treatment is symptomatic, however when an infectious etiology is found a specific treatment must be applied. This pathology has a poor prognosis, with a fifty percent mortality rate. When evolution is favorable, relapses are exceptional. The precise pathophysiological mechanism has not yet been determined. A better understanding of the cytokines' role should permit to consider new therapeutic routes.

[Severe pulmonary hypertension complicating a long treatment with dexfenfluramine].

The authors report a case of severe pulmonary hypertension after long-term dexfenfluramine treatment in a 48 year old man with no previous medical history. Dexfenfluramine, which has previously been reported to cause pulmonary hypertension, is an amphetamine-like anorexic agent, a pharmacological group known to predispose to this type of side effect. The possibility of this complication should be born in mind before prescribing the drug. In particular, it would seem to be particularly important not to exceed the recommended length of treatment especially as potential reversibility of pulmonary hypertension on withdrawal of the drug has been reported in one case.

[Cardiac tamponade in severe hypothyroidism. A rare cause].

Pericardial effusion frequently occurs in patients with hypothyroidism, and this fully justifies the use of echocardiography at the time of diagnosis and during the follow-up of hypothyroidism. Signs indicating that the pericardial effusion is poorly tolerated are rare, and the development of pericardial tamponade is exceptionally reported. A case of tamponade in an elderly woman with severe hypothyroidism is described here. Some physiopathological particularities are emphasized, together with the value of echocardiography for the diagnosis and that of pericardial drainage for the treatment.

[Compression of the coronary trunk by aneurysm of the antero-left Valsalva sinus associated with acute mitral insufficiency caused by rupture of the chordae following valvular prolapse. Successful triple surgical operation in a 66-year old patient].

Tearing of the chordae is a common complication of prolapse of the mitral valve; which becomes increasingly common with age. In contrast, aneurysm of the Valsalva sinus is rare in patients over 65 years of age. The antero-left sinus is an unusual location, but may be complicated by compression of the left coronary artery, which is reported in 16 cases in the literature. The case reported is unusual due to the combination in a 66-year old subject of acute mitral incompetence, due to tearing of the chordae following prolapse of the mitral valve, and an aneurysm pressing on the coronary trunk whilst remaining asymptomatic. Complete correction of the lesions was successfully achieved by surgery.
