In this cross-sectional study we evaluated T-cell responses using several assays to determine immune correlates of HIV control that distinguish untreated viraemic controllers (VC) from noncontrollers (NC) with similar CD4 counts. Samples were taken from 65 ART-naïve chronically HIV-infected VC and NC from Thailand with matching CD4 counts in the normal range (>450 cells/μl). We determined HIVp2...
A series of 2-benzoxazolinone, diazocoumarin and quinazoline derivatives have been shown to inhibit HIV replication in cell culture. To understand the pharmacophore properties of selected molecules and design new anti-HIV agents, quantitative structure–activity relationship (QSAR) study was developed using a descriptor selection approach based on the stepwise method. Multiple linear regression ...
INTRODUCTION The existing diagnostic algorithms for sputum smear-negative tuberculosis (TB) are complicated, time-consuming, and often difficult to implement. The decision to initiate TB treatment in resource-limited countries is often largely based on clinical predictors. We sought to determine the clinical predictors and accuracy of empiric TB treatment initiation in HIV-infected sputum smear...
BACKGROUND Effective tuberculosis (TB) control in HIV-prevalent settings is hindered by absence of accurate, rapid TB diagnostic tests. We evaluated the accuracy of a urine lipoarabinomannan (LAM) test for TB diagnosis in South Africa. METHODS Hospitalized adults with signs and/or symptoms of active TB were enrolled. Sputum smear microscopy and mycobacterial culture, mycobacterial blood cultu...
Accurate and timely diagnosis of infection status in infants born to women infected with human immunodeficiency virus (HIV) is of paramount importance. The comparative accuracy of five diagnostic decision rules was evaluated in 208 HIV-exposed infants (32 infected, 176 uninfected) based on laboratory testing during the first 6 months of life. Diagnostic rules A and B, which required single bloo...
background hiv and hcv infections are basic issues of many health systems. since hiv and hcv are transmitted similarly, it is common to become infected by them simultaneously. no consensus exists on the effect of hcv infection on the survival of hiv-infected patients. objectives this study aimed to investigate the issue in a relatively large cohort of patients who had a high prevalence of this ...
BACKGROUNDS Disseminated Penicillium marneffei infection is one of the most common HIV-related opportunistic infections in Southeast Asia. Immune reconstitution inflammatory syndrome (IRIS) is a complication related to antiretroviral therapy (ART)-induced immune restoration. The aim of this report is to present a case of HIV-infected child who developed an unmasking type of IRIS caused by disse...
An intravenous solution of 99% pure globulin (hyperimmune IgG, HIVIG) was obtained from pooled plasma of selected human immunodeficiency virus (HIV-1)-seropositive asymptomatic donors with greater than 400 CD4+/microliters cells per microliter and a high titer of antibody to HIV-1 p24 protein. HIVIG had high titers of antibody to p24, glycoprotein 41 (gp41), and gp120, group-specific neutralizi...
background: the aim of the present study was to investigate the immunomodulation effects of aqueous garlic extract (age) in the cultured macrophages infected by leishmania major . methods: after j774 macrophages proliferation in rpmi1640 and incubation with leishmania for 72 hours, age was added in doses of 9.25, 18.5, 37, 74 and 148 mg/ml for 18, 24 and 48 hours and cell culture supernatants w...
BACKGROUND The accurate diagnosis of TB in HIV-infected patients, particularly with advanced immunosuppression, is difficult. Recent studies indicate that a lipoarabinomannan (LAM) assay (Clearview-TB(R)-ELISA) may have some utility for the diagnosis of TB in HIV-infected patients; however, the precise subgroup that may benefit from this technology requires clarification. The utility of LAM in ...
