A aspergilose invasiva em pacientes com aids, embora incomum, é relevante pela apresentação clínica peculiar e alta letalidade. Este relato descreve os casos de dois pacientes com aids com grave imunossupressão celular e neutropenia prévia, os quais tiveram aspergiloma pulmonar primário, com disseminação para mediastino, vértebras e medula espinhal, evoluindo para óbito apesar do tratamento antifúngico. O segundo paciente, que tinha lesões cavitárias múltiplas no cérebro e infecção ocular e pulmonar, recuperou-se após tratamento com voricanazol, itraconazol e com drogas para aumentar o número de neutrófilos e de linfócitos CD4+. Estes casos demonstram o risco de infecção por Aspergillus após episódios de neutropenia em pacientes com aids e alertam para o início precoce de terapia antifúngica eficaz.

Although uncommon, invasive aspergillosis in the setting of AIDS is important because of its peculiar clinical presentation and high lethality. This report examines two AIDS patients with a history of severe cellular immunosuppression and previous neutropenia, who developed subacute invasive aspergillosis. One female patient developed primary lung aspergilloma, with dissemination to the mediastinum, vertebrae, and spine, which was fatal despite antifungal treatment. The second patient, who had multiple cavitary brain lesions, and eye and lung involvement, recovered following voriconazole and itraconazole, and drugs for increasing neutrophil and CD4+ lymphocyte levels. These cases demonstrate the importance of Aspergillus infections following neutropenia in AIDS patients, and emphasize the need for early and effective antifungal therapy.

Liver histological improvement after treatment for chronic hepatitis C in patients co-infected with human immunodeficiency virus-1 (HIV-1) has been described. Paired liver biopsies in twenty six HCV/HIV co-infected patients were compared to determine factors possibly associated with histological improvement. The patients were submitted to a liver biopsy before treatment for hepatitis C and 25 months after the end of treatment. Fragments of the liver biopsy obtained before and after treatment were compared regarding the following parameters: histological activity index (HAI) and degree of fibrosis (Knodell); intensity of collagen deposits (Sirius Red staining) and degree of stellate cell activation (alpha-smooth muscle actin labeling). The ratios of the post and pre-treatment variables were related through logistic regression to body mass index (BMI), alcohol ingestion, HCV genotype, HCV viremia, presence of hepatic iron and pre-treatment hepatic steatosis. A negative RNA test in the 24th week of treatment was associated with improvement in fibrosis, collagen deposits and stellate cell numbers. The other variables analyzed did not correlate to an improvement in hepatic histology after hepatitis C treatment. Reduction in HCV viremia during treatment may result in reduced hepatic fibrosis even in patients without a sustained virological response.

São apresentados e discutidos dois casos de anemia hemolítica auto-imune que ocorreram durante o tratamento da hepatite crônica pelo vírus C, com interferon peguilado alfa 2a e ribavirina, em pacientes co-infectados pelo HIV. A ocorrência de anemia hemolítica grave em etapa tardia, após o sexto mês da terapêutica, recomenda que o controle dos níveis de hemoglobina deva ser feito durante todo o período do tratamento , mesmo nos pacientes que apresentam níveis estáveis de hemoglobina nos meses precedentes.

Two cases of autoimmune hemolytic anemia that occurred during the treatment of chronic hepatitis C with pegylated alpha-2a interferon and ribavirin, in HIV coinfected patients, are presented and described. The late occurrence (after six months of therapy) of this severe hemolytic anemia leads to the recommendation that hemoglobin levels should be monitored throughout the treatment period, even among patients who presented stable hemoglobin levels in the preceding months.

Infecção disseminada por Cryptococcus neoformans foi observada em um recém-nascido que apresentava febre e sintomas respiratórios desde o 52º dia de vida. A mãe tinha infecção pelo vírus da imunodeficiência humana e apresentou infecção pulmonar e meningite criptocócica. Este é um caso raro de uma infecção criptocócica com provável transmissão materno-fetal.

Disseminated infection with Cryptococcus neoformans was observed in a newborn infant who presented fever and respiratory symptoms since the 52nd day of life. The mother was infected by human immunodeficiency virus and presented pulmonary and meningeal cryptococcal infection. This is a rare case of cryptococcal infection with probable maternal-fetal transmission.

É reportado um caso grave de Síndrome de Guillain-Barré (SGB) caracterizado por tetraplegia flácida arreflexa e sinais de instabilidade autonômica relacionado com infecção aguda pelo HIV-1, e a ocorrência de episódios de recidivas coincidentes com a detecção do RNA-HIV-1 no sangue, durante fases de tratamento irregular com antiretrovirais. O paciente encontra-se assintomático há 3 anos e com a carga viral do HIV-1 abaixo do limite de detecção. A ocorrência de SGB, neste caso, pode estar relacionada com alterações da resposta imunológica ocasionada por desequilíbrio na relação hospedeiro-HIV devido ao aumento da viremia do HIV-1.

We report a severe case of Guillain-Barré syndrome (GBS) characterized by flaccid areflexive tetraplegia and signs of autonomic instability related to acute HIV-1 infection, and the occurrence of relapse episodes coinciding with the detection of HIV-1 RNA in blood during the phase of irregular treatment with antiretroviral agents. The patient has been asymptomatic for 3 years and has an HIV-1 load below the limit of detection. The recurrence of GBS in this case may be related to alterations of the immunologic response caused by disequilibrium in the host-HIV relationship due to the increase in HIV-1 viremia.

Os autores relatam caso de infecção cutânea disseminada pelo Sporothrix schenckii em paciente de 30 anos, previamente assintomático e portador de infecção pelo HIV. Observou-se comprometimento cutâneo extenso com coleções supurativas e ulcerações. O agente foi isolado em cultura de abscesso. O tratamento com anfotericina B forma lipossomal mostrou-se eficaz.

TThe authors report a case of disseminated cutaneous infection with Sporothrix schenckii in a previously asymptomatic HIV-infected 30 year-old man. Extensive cutaneous involvement was observed with suppurative collections and ulcerations. The agent was isolated in culture. Treatment with liposomal amphotericin B proved to be effective.
