The early diagnosis of herpes simplex encephalitis (HSE) is essential because early introduction of antiviral therapy can significantly reduce the mortality of this disease. Herpes simplex virus (HSV) DNA detection in cerebrospinal fluid (CSF) samples is a rapid, noninvasive, specific, and highly sensitive method for HSE diagnosis. Neurodiagnostic methods(More)
HIV-infected women from S o Paulo city were enrolled in a cross-sectional study on Human Papillomavirus (HPV) and cervical intraepithelial neoplasia (CIN) prevalence and their association with laboratory markers of AIDS, namely HIV viral load and CD(4)(+) cell counts. A cervical specimen was collected and submitted to Hybrid Capture, a test for HPV viral(More)
A group of 208 human immunodeficiency virus (HIV)-infected women in Brazil were studied for the presence of human papillomavirus with the general SPF(10) PCR primer set. Virtually all (98%) women were found positive for human papillomavirus (HPV) DNA. Genotyping by the reverse hybridization line probe assay (HPV-LiPA) revealed a high prevalence of multiple(More)
OBJECTIVE To evaluate the presence of JC virus DNA in CSF samples from Brazilian AIDS patients with focal lesions of CNS white matter without mass effect compatible with progressive multifocal leukoencephalopathy (PML). METHODS CSF samples from AIDS patients with neurological symptoms and a CT scan showing focal lesions of CNS white matter without mass(More)
INTRODUCTION Several presentations of neurologic complications caused by JC virus (JCV) in human immunodeficiency virus (HIV)-infected patients have been described and need to be distinguished from the "classic" form of progressive multifocal leukoencephalopathy (PMl). The objectives of this study were: 1) to describe the spectrum and frequency of(More)
The aim of this study was to characterize the urinary excretion of the BK (BKV) and JC (JCV) human polyomaviruses in a cohort of human immunodeficiency virus (HIV)-infected children and adolescents. One hundred and fifty-six patients were enrolled: Group I included 116 HIV-infected children and adolescents [median age = 11.4 years (y); range 1-22 y]; Group(More)
Few data are available about progressive multifocal leukoencephalopathy (PML) in patients with acquired immunodeficiency syndrome (AIDS) from Brazil. The objectives of this study were to describe the main features of patients with PML and estimate its frequency among AIDS patients with central nervous system (CNS) opportunistic diseases admitted to the(More)
A total of 316 samples of nasopharyngeal aspirate from infants up to two years of age with acute respiratory-tract illnesses were processed for detection of respiratory syncytial virus (RSV) using three different techniques: viral isolation, direct immunofluorescence, and PCR. Of the samples, 36 (11.4%) were positive for RSV, considering the three(More)
A severely immune-suppressed AIDS patient was suspected of suffering from BK virus (BKV) meningoencephalitis, after being studied for common causes of neurological complications of co-infectious origin. Polymerase chain reaction (PCR) and sequence analysis of cerebrospinal fluid and brain samples, confirmed the presence of BKV. His clinical condition(More)
BACKGROUND Respiratory syncytial virus (RSV) has been implicated in the etiology of adult community-acquired pneumonia (CAP). We investigated RSV infection in Chilean adults with CAP using direct viral detection, real-time reverse-transcription polymerase chain reaction (rtRT-PCR), and serology (microneutralization assay). METHODS RSV, other respiratory(More)
