BACKGROUND Patients receiving combination antiretroviral therapy (cART) might continue treatment with a virologically failing regimen. We sought to identify annual change in CD4(+) T-cell count according to levels of viraemia in patients on cART. METHODS A total of 111,371 CD4(+) T-cell counts and viral load measurements in 8,227 patients were analysed. Annual change in CD4(+) T-cell numbers ...

Background: Hepatitis activity index (HAI) and fibrosing stage are two important findings during the evaluation of liver samples in patients with chronic hepatitis B. The aim of this study was to determine the HAI and fibrosing stage in patients with anti-HBe positive chronic hepatitis B. Methods: Liver biopsy slides of 72 patients were evaluated at the Department of Pathology in two teaching ...

conclusions our findings showed that hcv infection could lead to increased expression level of tlr7 mrna in peripheral blood cells of hcv infected samples. the viral load and genotypes of hcv did not affect the mrna expression levels of tlr2 and tlr7. background hepatitis c virus (hcv) is an important human pathogen affecting an estimated 120 – 170 million individuals in the world. toll-like re...

Background: Despite the considerable advances in acquired immunodeficiency syndrome (AIDS) treatment and management, finding the cure for this disease has been hindered by emerging challenges such as virus resistance and treatment failures. The purpose of this study is to compare the cytokine profiles of patients with successful treatment and patients with unsuccessful treatment to gain a bette...

Although it is a standard practice in high-income countries, determination of the human immunodeficiency virus (HIV) load is not recommended in developing countries because of the costs and technical constraints. As more and more countries establish capacity to provide second-line therapy, and as costs and technological constraints associated with viral load testing decrease, the question of wh...

Plasma viral load is helpful in monitoring systemic HIV infection but the relationship between plasma viral load and CNS functioning remains unclear. Equivocal results have been reported on the relationship between plasma viral load and cognitive functioning. The present study tested cognitive functions with a standardized neuropsychological battery consisting of 28 test scores. Participants (N...

BACKGROUND Recent papers have suggested that expanded combination antiretroviral treatment (cART) through lower viral load may be a strategy to reduce HIV transmission at a population level. We assessed calendar trends in detectable viral load in patients recruited to the Australian HIV Observational Database who were receiving cART. METHODS Patients were included in analyses if they had star...

AIM To explore factors associated with persistent hepatitis B virus (HBV) infection in a cohort of hepatocellular carcinoma (HCC)-affected families and then investigate factors that correlate with individual viral load among hepatitis B surface antigen (HBsAg)-positive relatives. METHODS We evaluated non-genetic factors associated with HBV replication in relatives of patients with HCC. Relati...

BACKGROUND Routine viral load monitoring of patients on antiretroviral therapy (ART) is not affordable in most resource-limited settings. METHODS A cross-sectional study of 496 Ugandans established on ART was performed at the Infectious Diseases Institute, Kampala, Uganda. Adherence, clinical and laboratory parameters were assessed for their relationship with viral failure by multivariate log...
