OBJECTIVES The World Health Organization (WHO) recommends screening HIV-infected people for cryptococcal antigens to identify cryptococcosis, a major cause of AIDS-related deaths. As the burden of cryptococcosis is unknown in South Africa's KwaZulu-Natal province, we assessed the cryptococcal antigenuria prevalence among newly diagnosed HIV-infected adults there. METHODS We conducted a cross-...

OBJECTIVES To investigate factors that predict speed of recovery and long-term CD4 cell count in HIV-1 seroconverters initiating combination antiretroviral therapy (cART), and to quantify the influence of very early treatment initiation. We make use of all pre-treatment CD4 counts, because analyses using only a single observation at initiation may be subject to biases. METHODS We used data fr...

BACKGROUND While CD4 strongly predicts mortality on antiretroviral therapy (ART), estimates from programmatic data suffer from incomplete patient outcomes. METHODS We conducted a pooled analysis of one-year mortality data on ART accounting for lost patients. We identified articles reporting one-year mortality by ART initiation CD4 count. We estimated the average mortality among those lost as ...

BACKGROUND CD4+ cell counts reflect immunologic status of human immunodeficiency virus (HIV) patients. Recommended CD4+ cell counts for the initiation of highly active antiretroviral therapy (HAART) has increased over the past several years in various HIV treatment guidelines. We investigated the trend of CD4+ cell counts at diagnosis and treatment start using data from the Korea HIV/acquired i...

OBJECTIVE To evaluate the absolute CD4 cell counts of all the newly diagnosed HIV-infected persons who presented at the Ladymeade Reference Unit (LRU), which serves as the national HIV/AIDS referral and treatment center for the country of Barbados. DESIGN AND METHODS The study group was comprised of HIV-infected adults who had been diagnosed with HIV infection and referred to the LRU between ...

BACKGROUND CD4 testing is the recognized gold standard used to stage HIV/AIDS, guide treatment decisions for HIV-infected persons and evaluate effectiveness of therapy. The need for a less expensive surrogate marker that can be used in resource-limited setting is however necessary. The study sought to assess the suitability of Total lymphocyte count (TLC) as a surrogate marker for CD4 count in ...

BACKGROUND Safety and effectiveness of efficacious antiretroviral (ARV) regimens beyond single-dose nevirapine (sdNVP) for prevention of mother-to-child transmission (PMTCT) have been demonstrated in well-controlled clinical studies or in secondary- and tertiary-level facilities in developing countries. This paper reports on implementation of and factors associated with efficacious ARV regimens...

Immunoregulatory CD4(+)CD25(+) T cells play an important role in the induction and maintenance of peripheral self-tolerance. These professional regulatory cells prevent the activation and proliferation of potentially autoreactive T cells that have escaped thymic deletion. Therefore, CD4(+)CD25(+) T cells are believed to possibly play an important role in pathogenic autoimmune diseases. We measu...

AIM To evaluate the correlation between the levels of CD4, CD8 and CD25 cells and SLE disease in active phase and in remission. METHODS A total of 25 SLE patients, aged between 18-60 years, and fulfilling the ACR criteria with preferential Renal and CNS involvement were included in this study. Baseline CD4/CD8 and CD25 counts, lab parameters etc were conducted. Approximately at the end of 6 m...

BACKGROUND Little is known about the associations between CD4(+) cell counts, human immunodeficiency virus (HIV) load, and human papillomavirus "low-risk" types in noncancerous clinical outcomes. This study examined whether CD4(+) count and HIV load predict the size of the largest anal warts in 976 HIV-infected women in an ongoing cohort. METHODS A linear mixed model was used to determine the...
