RESUMO

Aunque la resistencia a la infección por Listeria monocytogenes requiere que la inmunidad celular este indemne, la listeriosis es una enfermedad poco frecuente en los pacientes VIH+ y existen únicamente alrededor de unos 50 casos publicados. Se presentan los dos únicos enfermos VIH+ con infección por L. monocytogenes atendidos en nuestro hospital desde el inicio de la epidemia del sida en 1981. Caso 1: Varón VIH+ con 364 linfocitos CD4+ por mm3 que ingresó por cefalea occipital y fiebre. La tomografía axial computarizada cerebral fue normal y en el cultivo del líquido cefalorraquídeo creció L. monocytogenes. Se trató favorablemente con ampicilina y tobramicina. Caso 2: Varón de 47 años VIH+ con 44 linfocitos CD4+/ mm3 y cirrosis hepática por VHC que ingresó por fiebre elevada y distensión abdominal. Realizaba profilaxis para PCP con pentamidina IV. Con el diagnóstico de peritonitis bacteriana espontánea se extrajeron 3 hemocultivos y se inició tratamiento con ceftriaxona. Desarrolló encefalopatía hepática y falleció a las 72 h del ingreso. Postmortem se recibió crecimiento de L. monocytogenes. La listeriosis es una enfermedad poco frecuente en los enfermos VIH+, que esporádicamente produce cuadros de difícil diagnóstico, sobre todo en los enfermos que no realizan profilaxis para PCP con cotrimoxazol (AU)

RESUMO

Although resistance to Listeria monocytogenes infection requires intact T-cell mediated immunity, listeriosis is an infrequent problem in patients with HIV infection and only about 50 patients have been reported to date. Only two patients with HIV and L. monocytogenes have been attended in our hospital since the beginning of aids epidemic in 1981. Case 1: a man with HIV and 364 CD4+ cells/mm3 presented fever and occipital headache. The cerebral scan was normal and L. monocytogenes grew in licuor culture. He was outcome after treatment with ampicillin and tobramycin. Case 2: a 47 years old man with HIV, 44 CD4+ cells/mm3 and hepatic virus C cirrhosis was admitted to the hospital because fever and abdominal distension. He was on menstrual pentamidine prophylaxis for Pneumocystis carinii pneumonia (PCP). Bacterial peritonitis was diagnosed and the patient begun treatment with ceftriaxone. The patient dead 72 hours later with hepatic encepholopathy. Postmortem L. monocytogenes grew. Listeriosis is an infrequent disease in patients with HIV that causes difficult diagnostic problems, principally in patients without prophylaxis with cotrimoxazole for PCP.

RESUMO

BACKGROUND: Left-sided endocarditis in HIV-infected patients has an special clinical, epidemiological and microbiological characteristics and its relationship with drug addicts subjects is unknown. PATIENTS AND METHODS: Since 1986 up to 1996 we have been diagnosed 214 episodes of infective endocarditis in 190 HIV-infected patients. In 34 cases (15%) there was left-sided endocarditis. These patients are described. RESULTS: Mean age was 30 years and 28 were male (82%). Thirty patients had been intravenous drug addicts (IVDA) but only 18 were active-IVDA. In three cases the endocarditis was nosocomial. Mean CD4+ lymphocyte count was 176 per mm3 and 59% were AIDS-patients. Tuberculosis was the most frequent opportunistic infection (14 cases). The presentation was subacute in 70% and the most important symptom was fever. Only 3 (9%) had septic emboli in chest X-ray. The affected valve was mitral in 31 patients (91%). The blood culture was negative in 21 episodes (62%) and only in 6, Staphylococcus aureus was isolated. The mortality was 18% and 68% were outcome without any problem. CONCLUSIONS: Left-sided endocarditis in patients with HIV infection is a very serious problem. It seems to affect to patients with severe immunosuppression and the culture blood may be negative. Its diagnosis is difficult and the mortality is elevated.

RESUMO

Fundamento: La endocarditis de localización izquierda en los pacientes VIH+ tiene unas especiales caracteristicas clinicas, epidemiológicas y microbiológicas y es desconocida su relación con la drogadicción. Pacientes y métodos: Entre 1986 y 1996 se diagnosticaron 214 episodios de endocarditis infecciosa en 190 pacientes VIH+. En 34 casos (15%) existió endocarditis de válvulas izquierdas (EVI). Se describen sus hallazgos clínicos, inmunológicos, epidemiológicos y evolutivos. Resultados: La edad media fue 30 años y 28 (82%) eran varones. 30 habían sido drogadictos (88%) y 18 continuaban con consumo activo. En 3 casos, la EVI fue nosocomial. La media de linfocitos CD4+ fue de 176 por mm3 y el 59 porciento cumplían criterios de sida. La infección oportunista diagnosticada con mayor frecuencia fue la tuberculosis (14 casos). La evolución fue subaguda en el 70 porciento y la fiebre la manifestación clínica fundamental. Sólo 3 (9%) presentaron émbolos sépticos en la radiografía de tórax. La localización más frecuente fue la mitral (31 pacientes, 91 porciento). En 21 episodios (62 %) los hemocultivos fueron negativos y sólo en 6 (18%) el responsable fue el Staphylococcus aureus. La mortalidad fue del 18% y el 68 porciento curaron sin secuelas. Conclusiones: La EVI en los pacientes con infección por VIH aparece de forma subaguda, en los gravemente inmunodeprimidos y con frecuencia los hemocultivos son negativos. Tiene una elevada mortalidad y su diagnóstico es difícil (AU)

RESUMO

Polymicrobial endocarditis (PE) is uncommon, whether in series of cases of polymicrobial bacteriemia or of endocarditis. Among the 201 cases of infective endocarditis seen between 1986 and 1995 by an infectious diseases service, 12 patients had PE (6%). Nine were males, mean age was 28 years and ten were active intravenous drug users. All of them were HIV (+) and 50% had AIDS. Eleven subjects had infection of the tricuspid valve and 58% developed septic pulmonary emboli. The most common organism encountered was Staphylococcus aureus in 8 patients followed by Streptococcus viridans and S. pneumoniae in three. The most common combinations of organisms were S. aureus and S. pneumoniae in 3 cases and S. aureus and Pseudomonas aeruginosa in two. Two patients died, one with Xantomona maltophilia and another with Candida albicans. The symptoms of PE were usually indistinguishable from endocarditis caused by a single organism and the prognosis depended on the species rather than the number of organisms isolated.
