RESUMO

We describe the case of a young HIV-positive patient undergoing three-drug antiretroviral therapy that included a protease inhibitor for 9 months, who was admitted to the hospital with an acute myocardial infarction. A coronary angiogram revealed occlusion caused by a thrombus in the proximal third of the anterior descending artery. Complete recanalization was obtainedafter an angioplasty was performed. At the time of the infarction, only the triglyceride levels were found to be high. Metabolic alterations associated with the prolonged use of protease inhibitors have been described such as an increase in the triglyceride and the cholesterol serum levels, diabetes, resistence to insulin, lipodystrophy, and pancreatitis. The consequences of chronic hyperlipidemia are well known in the medical literature, especially premature coronary artery disease. No family history of coronary disease was identified in this patient. Whether the genesis of this localized thrombosis was due to a change in the metablism of the vascular endothelium caused by the protease inhibitors, or by related dyslipidemia, is still to be determined. In this case, the data suggest a strong link between coronary insufficiency and prolonged use of the protese inhibitor.

RESUMO

A meningite neutrofílica persistente é raramente diagnosticada e é caracterizada pelo predomínio neutrofílico na contagem diferencial do número de leucócitos nas amostras de líquido cefalorraquidiano retiradas após sete dias de tratamento adequado. O paciente aqui descrito é soropositivo para o HIV, apresentou febre e confusão mental durante 4 meses e pleocitose neutrofílica na análise liquórica por mais 5 meses. Foi tratado desde o início com tuberculostáticos. Durante três meses as reações imunológicas, as culturas e as pesquisas diretas foram negativas. No sexagésimo dia de internação, a pesquisa de bacilo álcool-ácido resistente (BAAR) no líquor foi positiva e a cultura confirmou a presença de Mycobacterium tuberculosis resistente à isoniazida. Vários fatores podem provocar esta evolução incomum. O comprometimento da imunidade celular, principalmente na liberação de citocinas pró-inflamatórias como a IL 8 e o FNT. O uso concomitante de medicações que poderiam alterar a concentração liquórica dos tuberculostáticos e o aparecimento crescente de cepas multirresistentes foram discutidos.

Persistent neutrophilic meningitis is rarely found and it is characterized by predominance of the number of neutrophils in samples of C SF (cerebrospinal fluid) from the patient after seven days of treatment. The above patient in HIV positive; he has developed fever and mental disorder for 4 months and has presented neutrophilic pleocytosis in analysis of CSF for more than 5 months. Since the beginning or the treatment he has taken antituberculous drugs and corticosteroids. For 3 months, the serologic evaluation, smears and cultures were negative. On the 60th day in hospital, the investigation of acid-fast bacilli in CSF was positive and culture confirmed the presence of Mycobacterium tuberculosis resistant to isoniazid. Several factors that may have caused this uncommon development were discussed: the disturbance of cell-mediated immunity, mainly in release of IL 8 and TNF, the simultaneous use of medicines that could alter the CSF concentration of antituberculous drugs, and the increasing number of multiresistant strains.
