Abstract
BACKGROUND Delayed CD4 recovery after initiating antiretroviral therapy (ART) is a novel potential mechanism by which alcohol consumption leads to increased morbidity and mortality in people with HIV. We hypothesized that alcohol consumption at ART initiation is associated with slower CD4 recovery. METHODS We retrospectively analyzed 2 pooled longitudinal alcohol/HIV cohorts (2014-2019) in St. Petersburg, Russia. Eligible participants initiated the first ART during parent studies; had alcohol consumption assessed by the blood biomarker, phosphatidylethanol (PEth), at the last research visit before ART initiation; and had ≥1 CD4 count measurement before and after initiating ART. Participants were stratified by low, moderate, and high PEth (<8, 8-80, and >80 ng/mL, respectively). We used random-effects piecewise linear regression models to estimate CD4 recovery, defined as CD4 count change per 30 days after ART initiation, by the alcohol group. RESULTS Of 60 eligible participants, median age was 34 years and 28% were female. The median pre-ART PEth in the low, moderate, and high PEth groups were <8, 23, and 232 ng/mL, respectively. After starting ART, the CD4 count increased by 13.60 cells/mm3/mo (95% CI: 0.33 to 26.87) with low PEth, 0.93 cells/mm3/mo (95% CI: -6.18 to 8.04) with moderate PEth, and 2.33 cells/mm3/mo (95% CI: -3.44 to 8.09) with high PEth. CONCLUSIONS Among Russians with HIV, we observed faster CD4 recovery after ART initiation in those with low alcohol consumption compared with those with moderate and high alcohol consumption, as assessed by PEth. This analysis provides further evidence for the possible value of alcohol reduction interventions for people with HIV who are initiating ART.

J Int AIDS Soc 2014; 17:18651. [PMID: 24594114 PMCID: PMC3942566 DOI: 10.7448/ias.17.1.18651] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2013] [Revised: 11/19/2013] [Accepted: 01/17/2014] [Indexed: 12/19/2022] Open
Abstract
INTRODUCTION The prognostic role of CD4 response in the first six months of treatment in patients achieving early viral suppression during HIV treatment is unclear. METHODS This was a cohort study of HIV-positive adults initiating antiretroviral therapy (ART) between April 2004 and August 2007 who achieved viral suppression (<400 copies/ml) by six months on treatment in South Africa. Immunological response at six months was defined as: (1) absolute CD4 reached (<200 vs. ≥ 200 cells/ml); (2) absolute CD4 reached (0-49, 50-200 and ≥ 200 cells/ml); and (3) CD4 increase from ART initiation (<0, 0-49, 50-199 and ≥ 200 cells/ml). We used Cox regression models to determine the relationship between each definition and both new AIDS-defining condition and death. RESULTS A total of 4129 patients were eligible for analysis; 212 (5.1%) of those patients experienced a new AIDS-defining condition and 154 (3.7%) died. Smaller CD4 gains by six months were associated with higher hazards of progression to AIDS (CD4<50 vs. ≥ 200 cells/ml; adjusted hazard ratio (aHR): 2.6; 95% CI: 1.2-2.1) and death (aHR: 2.8; 95% CI: 1.4-5.7). A decrease in CD4 count since ART initiation through six months (aHR: 2.4; 95% CI: 1.2-4.9) and smaller CD4 count gains (0-49 cells/ml; aHR: 2.0; 95% CI: 1.2-3.4 and 50-199 cells/ml; aHR: 1.5; 95% CI: 0.9-2.2) were also associated with greater risk of progression to AIDS compared to an increase of ≥ 200 cells/ml. When we examined mortality differences by gender among this virally suppressed cohort, a higher proportion of males died compared to females, 4.7% versus 3.2%, p=0.01. However, in multivariable analysis, we did not observe any significant differences: aHR: 1.39; 95% CI: 0.98-1.95. CONCLUSIONS Patients on ART with poor CD4 recovery early in treatment are at greater risk of progression to new AIDS diagnosis or death despite viral suppression. Approaches to managing this sub-group of patients need further investigation.

Abstract
OBJECTIVES To analyze the prevalence of hepatitis B virus (HBV) co-infection and its influence on mortality and treatment outcome within a large AIDS cohort in Chile. METHODS Clinical and epidemiological data from the Chilean AIDS Cohort were retrospectively analyzed. Adult patients tested for hepatitis B surface antigen (HBsAg) during the time period of October 2001 to October 2007 were included. RESULTS Of 5115 cohort patients, 1907 met the inclusion criteria. The prevalence of HBV co-infection was 8.4%. Overall mortality rates were 2.15 and 1.77 per 100 person-years for HBsAg-positive and HBsAg-negative HIV patients, respectively, with a mortality rate ratio of 1.22 (95% confidence interval 0.58-2.54). Kaplan-Meier survival and Cox regression analysis did not show significant differences between the groups. Virological and immunological responses to antiretroviral therapy (ART) were not influenced by HBsAg status, but in co-infected patients, initial ART was more frequently changed. CONCLUSIONS The prevalence of hepatitis B co-infection was 8.4%, indicating a markedly elevated hepatitis B risk compared to the general population in Chile. Neither treatment outcome nor overall mortality was influenced by hepatitis B co-infection. Still, patients with hepatitis B co-infection had less stable ART regimens, which might be related to a higher risk of hepatotoxic drug effects.

Abstract
OBJECTIVES Patients starting highly active antiretroviral therapy (HAART) may have a suboptimal CD4 increase despite rapid virological suppression. The frequency and the significance for patient care of this discordant response are uncertain. This study was designed to determine the incidence of a discordant response at two time-points, soon after 6 months and at 12 months, and to determine the relationship with clinical outcomes. METHODS Data obtained in the UK Collaborative HIV Cohort Study were analysed. A total of 2584 treatment-naïve patients starting HAART with HIV viral load (VL) > 1000 HIV-1 RNA copies/mL at baseline and < 50 copies/mL within 6 months were included in the analysis. Patients were classified at either 6-10 (midpoint 8) months or 10-14 (midpoint 12) months as having a discordant (CD4 count increase < 100 cells/microL from baseline) or concordant response (CD4 count increase >or= 100 cells/microL). RESULTS Discordant responses occurred in 32.1% of patients at 8 months and in 24.2% at 12 months; 35% of those discordant at 8 months were concordant at 12 months. A discordant response was associated with older age, lower baseline VL, and (at 12 months) higher baseline CD4 cell count. In a multivariate analysis it was associated with an increased risk of death, more strongly at 12 months [incidence rate ratio (IRR) 3.35, 95% confidence interval (CI) 1.73-6.47, P < 0.001] than at 8 months (IRR 2.08, 95% CI 1.19-3.64, P = 0.010), but not with new AIDS events. CONCLUSIONS Discordant responders have a worse outcome, but assessment at 12 months may be preferred, given the number of 'slow' responders. Management strategies to improve outcomes for discordant responders need to be investigated.

Abstract
OBJECTIVES To analyse the role of thymic function and its association with cellular immunosenescence markers in patients with low-level CD4 T cell repopulation, despite complete HIV RNA replication control on highly active antiretroviral therapy (HAART). METHODS Cellular immunosenescence markers comparing patients with CD4 T cell counts <or=250 cells/mm(3) for >or=48 weeks (n = 11) and patients with a CD4 T cell count >or=500 cells/mm(3) (n = 11) were investigated. Both groups were also compared with 11 healthy volunteers of similar age. Naive CD4 T cell counts, beta- and delta-T cell rearrangement excision circles, recent thymic emigrants, replicative senescence marker, cell activation, and rate of apoptosis were analysed. The Mann-Whitney U-test was used to compare parameters between both low-level and high-level CD4 T cell repopulation groups, and healthy volunteers. RESULTS Our results showed a lower thymic activity in patients with low-level CD4 T cell repopulation, leading to a decline in CD4 T cell production. On the other hand, a higher activation along with a higher replicative senescence of CD4 T cells contributed to a higher rate of apoptotic CD4 T cells in this group of patients. CONCLUSIONS We propose a model with several different related mechanisms involved in premature immune senescence in HIV-infected patients with low-level CD4 repopulation on HAART. The understanding of such different mechanisms could help find effective strategies to prevent immune decay.

Abstract
The factors associated with discordant viroimmunological responses following antiretroviral therapy are unclear. We studied 1380 patients who initiated a protease inhibitor (PI)-based antiretroviral regimen and who fulfilled the criteria for inclusion. Of them, 255 (18.5%) had CD4 increases > or =100 cells/microl after 1 year of therapy despite detectable viral load (immunological responders); they were compared with 669 patients (48.5%) who had CD4 increases <100 cells/microl regardless of their final viral load (immunological nonresponders). Immunological responders had higher rates of sexual acquisition of HIV (p = 0.03), lower rates of clinical progression (p = 0.02), higher probabilities of being naive to antiretroviral therapy (p = 0.006) or to PI if antiretroviral experienced (p = 0.03), higher rates of receiving only nucleoside reverse transcriptase inhibitors in addition to the PI (p = 0.04), and lower baseline CD4 counts (p = 0.007) and higher viral loads (p = 0.009), as compared with nonresponders. Multivariate analysis revealed that sexual transmission of HIV (homosexual p = 0.004, heterosexual p = 0.03), no prior PI experience (p = 0.005), absence of clinical progression (p = 0.02), and lower baseline CD4 counts (p = 0.03) were independently associated with immunological response. However, these factors differed according to the patients' prior antiretroviral status, as higher baseline viral load was also associated with immunological response in antiretroviral-experienced patients (p = 0.02), whereas baseline CD4 count (p = 0.007) was the only predictive parameter in antiretroviral-naive patients. We conclude that immunological responses despite suboptimal viral suppression are common. Prior PI experience, HIV transmission category, baseline CD4 counts, and clinical progression were independently predictive of this condition, although the associated factors were different depending on the patient's prior antiretroviral history.

Abstract
To determine the factors associated with poor immunologic responses despite viral suppression in markedly immunocompromised patients (</=200 CD4 cells per microliter at baseline), individuals with less than 100 CD4 increases after 12 months of nelfinavir-based highly active antiretroviral therapy (HAART; n = 114) were compared to those with 100 or more CD4 increases (n = 338). Responders were more likely to be naïve to antiretroviral therapy (p = 0.009) and to protease inhibitors (p< 0.001), less likely to have undetectable viral load at baseline (p = 0.01), to be infected through injection drug use (p = 0.02), to receive two versus three daily nelfinavir doses (p = 0.05), and to have higher viral load (p< 0.001) and lower CD4 counts (p = 0.03) at baseline than nonresponders. Logistic regression analysis revealed that baseline viral load (odds ratio [OR] 0.76, 95% confidence interval [CI] 0.64-0.91), two daily nelfinavir doses (OR 1.85, 95% CI 1.12-3.03) and prior treatment with protease inhibitors (OR 1.85, 95% CI 1.11-3.07) were significantly predictive of poor immunologic responses. On the contrary, viral load had no predictive role in antiretroviral therapy (ART)-naïve patients (p = 0.7). We conclude that poor immunologic responses are common in these patients. Lower viral load at baseline is associated with poorer responses, which could be related to suboptimal prior antiretroviral therapy. In patients taking nelfinavir, administration in two versus three daily doses is also associated with worse immunologic responses.

Abstract
We carried out a longitudinal study to analyze the immune recovery of four patients with aggressive HIV-associated lymphoma (HIV+ Ly+) treated with highly active antiretroviral therapy (HAART) and high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation (ASCT). We also studied three control non-HIV-infected patients with lymphoma (HIV-Ly+) and six HIV patients on HAART without lymphoma (HIV+ Ly-). After 12 months of follow-up, the HIV HIV+Ly+ patients reached the pre-ASCT CD4+ levels, despite a transient decrease after the ASCT. All ASCT patients (HIV+Ly+ and HIV-Ly+) showed an increase in CD4+, CD4+ CD45RO+, and CD4+CD28+ T cells/microl. Although HIV+Ly+ patients had values of CD4+, CD4+CD45RO+, and CD4+CD28+ T cells/microl lower than the HIV-Ly+ patients, their recovery rate over the 12 months after ASCT appeared to be better. HIV+Ly+ patients had higher pre-ASCT plasma IL-7 levels than HIV-Ly+, however, these values decreased after ASCT. All ASCT patients showed a slight increase of TCR rearrangement excision circles (TRECs) and they did not have a different pattern of TREC evolution. We could not find differences between HIV+Ly+ patients 12 months after ASCT and HIV+Ly- in DNA-HIV (copies/10(6) cell). Overall, HIV+Ly+ patients showed an appropriate immune reconstitution 12 months after ASCT, and, interestingly, they had an amount of DNA-HIV copies similar to HIV+Ly- control patients in their CD4+ cells.
