This study confirms that ART delivery through a national programme in a resource-constrained setting can be effective. Most of the patients in the study showed a good clinical response to therapy, as indicated by significant weight gain and improvement in CD4 count. Around 82% of them had reached an advanced stage of illness (World Health Organization stage 3 or 4) at presentation, highlighting the need for early diagnosis and treatment. The overall mortality rate in our study was higher than reported from other developed and developing countries.10,11 Nevertheless, the post-90-day mortality rate was similar to the rate observed in another study.10. In line with previous studies, we found no significant association between TB and mortality.5,12 In a study from Uganda, TB was associated with increased mortality only in HIV patients with a CD4 count > 200 cells/µl.12 It may be that TB facilitates HIV viral replication to a greater extent in the earlier stages of HIV infection than during advanced ...
A paper published today in PLoS Medicine using CASCADE data has shown that there is no need to take into consideration the CD4 slope prior to the start of HIV therapy when deciding whether to initiate therapy.. The CASCADE Collaboration, is a large collaborative study of 25 cohorts of HIV patients with known date of seroconversion. Wolbers et al considered whether there was any evidence of an association between pre-therapy CD4 slope and the primary outcome (a first new AIDS-defining event or death).. A total of 2,820 HIV-positive patients initiating cART (combination antiretroviral therapy) were included in the study; the average pre-cART CD4 cell decline among them was 61 cells/ml/year. Of these, 255 experienced a new AIDS-related event or died after starting cART but the researchers found no evidence for an association between the primary outcome and the pre-cART CD4 slope or between survival and this slope. In addition, the rate of CD4 cell count decline was not significantly associated with ...

CD4+ Cell Count Declines Slowly, But Steadily, in Elite HIV Controllers, Small Study Finds, at TheBody.com, the complete HIV/AIDS resource.
Implementation of antiretroviral treatment (ART) guidelines, which emphasize maximal and durable suppression of viral load for the majority of individuals infected with HIV, has resulted in a substantial decline in morbidity and mortality. However, many asymptomatic patients are not at immediate risk of serious opportunistic diseases, the effectiveness of ART wanes over time due to HIV drug resistance, and there are short- and long-term toxicities of treatment. This motivates a comparison of two strategies: one which conserves treatments by deferring their use while the risk of opportunistic disease is low and one which aims for sustained virologic suppression, irrespective of disease risk.. In this large, long-term trial, patients will be randomly assigned to either the drug conservation (DC) or viral suppression (VS) group. Patients will be enrolled over a 3-year period and followed for an average of 7.5 years. The DC group will stop or defer ART until CD4 cell count declines to below 250 ...
A CD4+ count is a blood test to determine how well the immune system is working in people who have been diagnosed with human immunodeficiency virus (HIV). CD4+ cells are a type of white blood cell. White blood cells are important in fighting infections. CD4+ cells are also called T-lymphocytes, T-cells, or T-helper cells.. HIV infects CD4+ cells. The number of CD4+ cells helps determine whether other infections (opportunistic infections) may occur. The pattern of CD4+ counts over time is more important than any single CD4+ value because the values can change from day to day. The CD4+ pattern over time shows the effect of the virus on the immune system. In people infected with HIV who are not getting treated, CD4+ counts generally decrease as HIV progresses. A low CD4+ count usually indicates a weakened immune system and a higher chance of getting opportunistic infections.. ...

We have developed a model to determine whether asymptomatic HIV-infected individuals who have a rapid CD4 cell decline are a subgroup who might benefit from early antiretroviral therapy. Data were obtained from a subgroup of participants in the Concorde and EACG020 trials, two randomized, double-blind, comparative trials of immediate (IMM) versus deferred (DEF) zidovudine therapy in asymptomatic HIV-infected individuals. The subgroup comprised 297 patients (IMM = 154, DEF = 143) who had at least one CD4 cell count before and after randomization. The median CD4 cell count at randomization was 491 x 10(6)/L, and the median follow-up was 61 months. The rate of CD4 decline before and after randomization was estimated using multi-level linear regression analysis, and patients were stratified into quartiles according to the rate of CD4 cell decline before randomization. Outcome measures were the development of AIDS, a 50% drop in CD4 count from the baseline, and death. A Cox proportional hazards model was
Methods: In nine countries, we enrolled 1763 couples in which one partner was HIV-1-positive and the other was HIV-1-negative; 54% of the subjects were from Africa, and 50% of infected partners were men. HIV-1-infected subjects with CD4 counts between 350 and 550 cells per cubic millimeter were randomly assigned in a 1:1 ratio to receive antiretroviral therapy either immediately (early therapy) or after a decline in the CD4 count or the onset of HIV-1-related symptoms (delayed therapy). The primary prevention end point was linked HIV-1 transmission in HIV-1-negative partners. The primary clinical end point was the earliest occurrence of pulmonary tuberculosis, severe bacterial infection, a World Health Organization stage 4 event, or death ...
The majority of HIV-infected subjects with virologic suppression on antiretroviral therapy (ART) have a marked increase in CD4+ T-cell counts over the first year on treatment. However, a portion of these individuals show a suboptimal immune response and remain at an elevated risk for disease progression. The use of the CCR5 inhibitor maraviroc (MVC) is associated with enhanced CD4+ T-cell recovery in subjects who initiate ART. AIDS Clinical Trials Group (ACTG) A5256 studied the effect of ART intensification with MVC on CD4+ T-cell counts in subjects with suboptimal CD4 recovery despite sustained virologic suppression. Eligible subjects added MVC to their ART regimen, and continued MVC for 24 weeks. At week 24, subjects discontinued MVC and were followed for an additional 24 weeks off MVC.. Subjects were seen through week 48 for clinical and laboratory evaluations, including plasma HIV-1 RNA, CD4+ T-cell count, and safety laboratories. Subjects had 2 baseline visits prior to starting MVC. Study ...
The incidence of AIDS was higher in patients with a current CD4 count of 500-749 cells/µL compared to 750-999 cells/µL, but did not decrease further at higher CD4 levels. Results were similar in those virologically suppressed on combination antiretroviral therapy, suggesting immune reconstitution is incomplete until CD4 |750/µL Mocroft, A.; Furrer, H. J.; Miro, J.

HIVandHepatitis.com. CD4 cell count and CD4 cell percentage are key markers for determining disease progression and risk for opportunistic infection in HIV-infected patients.. These markers are of greatest use in treating the asymptomatic patient, in whom disease stage is more difficult to assess clinically and for whom laboratory measurements serve as guidelines for the initiation of therapy and opportunistic-infection prophylaxis.. However, providers in resource-constrained settings may not have access to this laboratory measurement or its cost may be prohibitive, resulting in the need for an alternative, surrogate marker. Given the decreasing costs and increased availability of antiretroviral therapy (ART) in the developing world, this is an issue of critical and increasing importance.. A number of previous studies indicate that the total lymphocyte count (TLC) may be useful as a surrogate marker of immune status in certain settings. However, controversy regarding the utility of the TLC ...
VL was more likely to be detectable if participants had OIs in the prior three months compared to when they did not (OR=4.0 (95% CI=1.9-8.6)). The CD4+ T cell counts declined 24.1 cells/µL per three months in intervals where the participants had OIs compared to an increase of 21.3 cells/µL per three months in intervals where they did not have OIs (adjusted difference in the rate of CD4+ T cell count change of 61.7 cells/µL per three months (95% CI=13.7-109.7), P value=0.012). The rate of CD4+ T cell count increase was 25.6 cells/µL per three months (95% CI=11.6-39.6) higher for females compared to males (p value ...
Results More than half (54.9%, 485/883) of all HIV positive patients presented with CD4 count of less than 250 cells/mm3. 20.7% (183/883) reported with CD4 count less than 50 cell/mm3, 9.5% (84/883) with CD4 count of less than 100 cells/mm3, 24.7% (218/883) with CD4 count of less than 250 cells/mm3, 16.0% (141/883) with CD4 count of less than 350 cells/mm3, 10.3% (91/883) with CD4 count of less than 500.

We applied Cox regression analysis to investigate the association between response to IFN-RBV and the development of new AIDS-defining conditions, non-liver-related death, and non-liver-related non-AIDS-related death. When we adjusted for age, sex, HIV transmission category, nadir CD4+ cell count, cART, HIV-RNA level below the limit of detection, and liver fibrosis, we found that the adjusted hazard ratio of each of these clinical endpoints was higher for non-responders than for responders, although it reached statistical significance only for non-liver-related death and non-liver-related non-AIDS-related death (Table 4). We carried out 2 sensitivity analyses. In the first, we excluded those patients with recurrent pneumonia as a new AIDS-defining condition and those who died of bacterial pneumonia. In the second, we did not exclude patients with recurrent pneumonia as a new AIDS-defining condition or those who died of bacterial pneumonia, although we did censor their follow-up until these ...
Background Life expectancy has increased for newly diagnosed HIV patients since the inception of combination antiretroviral treatment (cART), but there remains a need to better understand the characteristics of long-term survival in HIV-positive patients. We examined long-term survival in HIV-positive patients receiving cART in the Australian HIV Observational Database (AHOD), to describe changes in mortality compared to the general population and to develop longer-term survival models. Methods Data were examined from 2,675 HIV-positive participants in AHOD who started cART. Standardised mortality ratios (SMR) were calculated by age, sex and calendar year across prognostic characteristics using Australian Bureau of Statistics national data as reference. SMRs were examined by years of duration of cART by CD4 and similarly by viral load. Survival was analysed using Cox-proportional hazards and parametric survival models. Results The overall SMR for all-cause mortality was 3.5 (95% CI: 3.0-4.0). SMRs
HIV infection requires lifelong treatment with antiretroviral therapy (ART). In the earlier years of combination ART, although effective in managing HIV disease progression, ART was very toxic and poorly tolerated. Monitoring the impact of ART including updates to treatment, adherence, impact on HIV disease progression and overall mortality was critical to the understanding of HIV disease progression, and for providing guidance to the management and treatment of HIV patients. Even in the current era of highly tolerable and highly effective ART, ongoing monitoring remains important. AHOD is the largest, and longest running, data source in Australia monitoring the uptake and impact of HIV treatment.. ...
OBJECTIVE:: Inadequate CD4 cell count recovery despite full HIV RNA control occurs in 30% of HAART-treated HIV-infected patients. A better understanding of the relationship between T-cell dynamics and the HIV intracellular reservoir in HIV-infected patients failing to recover CD4 cell count following long-term HAART, is required. METHODS:: In a cross-sectional study T-cell turnover and homeostatic parameters featuring discordant responses were investigated in 27 immunologic non-responders (INR; CD4 count, ,/= 200 cells/mul; HIV RNA, ,/= 50 copies/ml), 15 virological non-responders (VNR; CD4 count, ,/= 350 cells/mul; HIV RNA, ,/= 10 000) and 22 full responders (FR; CD4 count, ,/= 500 cells/mul; HIV RNA, ,/= 50 copies/ml). RESULTS:: INR displayed significantly higher activated CD38CD8 than FR (P , 0.05) and was comparable to VNR (P , 0.05). As compared with VNR and FR, INR displayed the highest level of proliferating Ki67CD4 and apoptotic CD4 cells (P , 0.05). VNR presented lower proliferation and ...
A retrospective cohort study was performed to examine the extent and clinical significance of misclassification associated with using the current United States AIDS case defining category of an initial CD4 count | or = 200 cells x 10(6)/l (| or = 200) compared with a definition requiring two consecutive counts below this level. The main outcomes examined were the probability of subsequent CD4 counts | 200 x 10(6)/l (| 200) and progression times to AIDS and death. Of the 2025 predominantly male homosexual HIV-positive patients attending two hospital based HIV clinics with initial CD4 cell counts | or = 200, 1524 (75%) subsequently had consecutive counts | or = 200, but only half did so at the next CD4 count. Ten per cent had either no further or only non-consecutive counts | or = 200, and 15% had only one CD4 count available for analysis. The cumulative proportion of patients with a CD4 count | 200 at one year after a first count of | or = 200 was about twice (39%) that observed among the subgroup with

To develop a decision criterion for earlier ART initiation now, we examined 2 potential policy scenarios (ART initiation at CD4 counts ,0.350 × 109 cells/L vs. ,0.250 × 109 cells/L) over the next 5 years and their associated clinical and economic outcomes (Figure 1). These outcomes excluded any long-term benefits, detriments, or costs potentially associated with either decision beyond the 5-year horizon. Although the calculated outcomes included ART-related toxicities, they also excluded any excess toxicity that might be associated with earlier ART beyond the 5-year horizon. If ART is initiated at a CD4 count less than 0.350 × 109 cells/L, the trial may demonstrate in 5 years that a 0.350 × 109 cells/L initiation threshold provides a benefit (probability P) or that it produces equivalent outcomes to a 0.250 × 109 cells/L threshold (probability 1 − P). In the latter case, the associated costs of a 0.350 × 109 cells/L initiation threshold include not only those of earlier initiation but ...
I am a 35 years old HIV positive man and my CD4 count was 350 few months back. Then it increased to 510 within 3 months. |b|Is there any way of the CD4 increasing to 510 with in 3 months?|/b| Again after another three months it was 540. I took a herbal medicine when the CD4 count was at 350 and it was only for the first 3 months. But the doctors could not believe this and they are saying that this could be due to a diet change and at the same time they didnt want to show me my real results and hide the paper when I asked for it. To my knowledge, HIV cannot be cured, and even if I am cured the doctors will do more research on me. I know for sure that if I have HIV then there is no way CD4 can increase consistently. Please tell how did my CD4 count increase?

OBJECTIVES: Current British HIV Association (BHIVA) guidelines recommend that all patients with a CD4 count ,350 cells/μL are offered highly active antiretroviral therapy (HAART). We identified risk factors for delayed initiation of HAART following a CD4 count ,350 cells/μL.METHODS: All adults under follow-up in 2008 who had a first confirmed CD4 count ,350 cells/μL from 2004 to 2008, who had not initiated treatment and who had ,6 months of follow-up were included in the study. Characteristics at the time of the low CD4 cell count and over follow-up were compared to identify factors associated with delayed HAART uptake. Analyses used proportional hazards regression with fixed (sex/risk group, age, ethnicity, AIDS, baseline CD4 cell count and calendar year) and time-updated (frequency of CD4 cell count measurement, proportion of CD4 counts ,350 cells/μL, latest CD4 cell count, CD4 percentage and viral load) covariates.RESULTS: Of 4871 patients with a confirmed low CD4 cell count, 436 (8.9%) ...

CD4(+) lymphocyte count and human immunodeficiency virus (HIV) type 1 RNA level are useful for determining when to initiate antiretroviral therapy but are not used widely in developing countries due to the high cost. Heat-denatured protein 24 (p24) antigen is an inexpensive assay that predicts disease progression among persons with advanced disease but has not been assessed among persons with early-stage disease. Plasma levels of heat-denatured p24 antigen were quantified in baseline study-visit specimens obtained from injection drug users enrolled in a longitudinal cohort study of HIV-1 infection. Of the 494 study participants (median initial CD4(+) lymphocyte count, 518 lymphocytes/mm(3)), 90 (18%) progressed to acquired immunodeficiency syndrome within 5 years. p24 antigen level correlated with both CD4(+) lymphocyte count (r=-0.34; P,.0001) and HIV-1 RNA level (r=0.55; P,.0001). p24 antigen level ,5 pg/mL predicted disease progression, comparable with that of cutoff CD4(+) lymphocyte count ...
