Primary aspergilloma and subacute invasive aspergillosis in two AIDS patients.

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.

HCV virological response during treatment of chronic hepatitis C is associated with liver histological improvement in patients with HCV/HIV co-infection.

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.

Relationship between serum and saliva antibodies to Candida and isolation of Candida species from the mucosa of HIV-infected individuals.

Colonisation and infection by Candida species occur frequently in acquired immunodeficiency syndrome (AIDS), but their relationship to the humoral immunity against candidiasis is controversial. To evaluate the levels of antibodies to Candida in the serum and in the saliva of HIV-1-infected patients in relation to the presence of immunodeficiency, oral candidiasis and Candida colonisation, Candida was investigated in the urine and in the oral and anal mucosae of HIV-1-infected patients, AIDS patients and healthy controls. The levels of IgG, IgM and IgA antibodies to Candida were determined in the serum and in the saliva by immunoassay.

Autoimmune hemolytic anemia in HCV/HIV coinfected patients during treatment with pegylated alpha-2a interferon plus ribavirin.

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.

Vertical transmission of Cryptococcus neoformans from a mother coinfected with human immunodeficiency virus: case report.

Disseminated infection with Cryptococcus neoformans was observed in a newborn infant who presented fever and respiratory symptoms since the 52 nd 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.

Episodes of Guillain-Barré syndrome associated with the acute phase of HIV-1 infection and with recurrence of viremia.

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.
