Abstract
We aimed to explore the impact of sexual transmission modes on immune reconstitution after combined antiretroviral therapy (cART). We have retrospectively analyzed longitudinal samples from 1557 treated male patients with virological suppression (HIV-1 RNA<50 copies/ml) for at least 2 years. Both heterosexuals (HET) and men who have sex with men (MSM) patients showed an increasing annual trend in CD4+ T cell counts after receiving cART (HET, β: 23.51 (cell/µl)/year, 95% CI: 16.70 to 30.31; MSM, β: 40.21 (cell/µl)/year, 95% CI: 35.82 to 44.61). However, the CD4+ T cell recovery rate was much lower in HET patients than MSM patients, determined by both the generalized additive mixed model (P < 0.001) and generalized estimating equations (P = 0.026). Besides HIV-1 subtypes, baseline CD4+ T cell counts and age at cART initiation, HET was an independent risk factor for immunological non-responders (adjusted OR: 1.73; 95% CI: 1.28 to 2.33). HET was also associated with lower probability of achieving conventional immune recovery (adjusted HR: 1.37; 95%CI: 1.22 to 1.67) and optimal immune recovery (adjusted HR: 1.48, 95%CI: 1.04-2.11). Male HET patients might have poorer immune reconstitution ability even after effective cART. Early initiation of cART after diagnosis and clinical monitoring for male HET patients should be highly emphasized.

Determinants and neonatal outcomes of preeclampsia among women living with and without HIV at a tertiary hospital in Zambia: a review of medical records. Pan Afr Med J 2022; 43:110. [PMID: 36699973 PMCID: PMC9834805 DOI: 10.11604/pamj.2022.43.110.34390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Accepted: 10/17/2022] [Indexed: 01/27/2023] Open
Abstract
Introduction pre-eclampsia, a pregnancy-specific condition that occurs after 20 weeks of gestation, is a significant public health problem. In the extant literature, there are still conflicting reports on whether Human immunodeficiency virus (HIV) infection and antiretroviral therapy (ART) affect preeclampsia rates. We, therefore, explored the determinants and neonatal outcomes of preeclampsia among pregnant women living with and without HIV. Methods we reviewed delivery registers and neonatal files from the 1st January 2018, to 30th of September 2019 for women who delivered at Women and Newborn Hospital. The logistic regression model estimated the odds of preeclampsia and described the neonatal outcomes. Results the prevalence of preeclampsia was 7.7% (95% confidence intervals: 6.8 to 8.7). On ART, pregnant women with HIV infection were less likely to develop preeclampsia than those without HIV infection (aOR=0.50; 95% CI: 0.32 to 0.80). However, neonates born to women with preeclampsia were more likely to be admitted to kangaroo mother care than neonates born to normotensive women, regardless of the HIV-exposure status. Conclusion overall, the prevalence of preeclampsia was 7.7%, but it was less common among HIV-infected pregnant women receiving ART. Neonates born from women with preeclampsia are at increased risk of adverse outcomes, including admission to kangaroo mother care. These findings underscore the need for healthcare workers to direct their efforts on early diagnosis and detection of preeclampsia in pregnant women to prevent poor outcomes.

Evaluation of Clinical Biomarkers Related to CD4 Recovery in HIV-Infected Patients—5-Year Observation. Viruses 2022; 14:v14102287. [PMID: 36298842 PMCID: PMC9607521 DOI: 10.3390/v14102287] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 10/14/2022] [Accepted: 10/16/2022] [Indexed: 12/01/2022] Open
Abstract
Human Immunodeficiency Virus infection leads to the impairment of immune system function. Even long-term antiretroviral therapy uncommonly leads to the normalization of CD4 count and CD4:CD8 ratio. The aim of this study was to evaluate possible clinical biomarkers which may be related to CD4 and CD4:CD8 ratio recovery among HIV-infected patients with long-term antiretroviral therapy. The study included 68 HIV-infected patients undergoing sustained antiretroviral treatment for a minimum of 5 years. Clinical biomarkers such as age, gender, advancement of HIV infection, coinfections, comorbidities and applied ART regimens were analyzed in relation to the rates of CD4 and CD4:CD8 increase and normalization rates. The results showed that higher rates of CD4 normalization are associated with younger age (p = 0.034), higher CD4 count (p = 0.034) and starting the therapy during acute HIV infection (p = 0.012). Higher rates of CD4:CD8 ratio normalization are correlated with higher CD4 cell count (p = 0.022), high HIV viral load (p = 0.006) and acute HIV infection (p = 0.013). We did not observe statistically significant differences in CD4 recovery depending on gender, HCV/HBV coinfections, comorbidities and opportunistic infections. The obtained results advocate for current recommendations of introducing antiretroviral therapy as soon as possible, preferably during acute HIV infection, since it increases the chances of sufficient immune reconstruction.

Abstract
Background CD4+ cell count recovery after effective antiretroviral therapy (ART) is an important determinant of both AIDS and non-AIDS morbidity and mortality. Data on CD4+ cell count recovery after initiation of ART are still limited in Sub-Saharan Africa. The aim of this study was to assess CD4+ cell count recovery among HIV-infected adults initiating ART in an Ethiopian setting. Methods A retrospective cohort study of HIV-infected adults initiating ART between September 2008 and June 2019 was carried out. CD4+ cell count recovery was defined as an increase in CD4+ cell count of >100 cells/mm3 from baseline or achievement of a CD4+ cell count >500 cells/mm3 at 12 months after ART initiation. Factors associated with CD4+ cell count recovery were evaluated using logistic regression analysis. Results Of the 566 patients included in this study, the median baseline CD4+ cell count was 264 cells/mm3 (IQR: 192–500). At 12 months after ART initiation, the median CD4+ cell count increased to 472 cells/mm3, and the proportion of patients with CD4+ cell count < 200 cells/mm3 declined from 28.3 to 15.0%. A total of 58.0% of patients had an increase in CD4+ cell count of >100 cells/mm3 from baseline and 48.6% achieved a CD4+ cell count >500 cells/mm3 at 12 months. Among patients with CD4+ cell counts < 200, 200–350 and >350 cells/mm3 at baseline, respectively, 30%, 43.9% and 61.7% achieved a CD4+ cell count >500 cells/mm3 at 12 months. In multivariable analysis, poor CD4+ cell count recovery (an increase of ≤100 cells/mm3 from baseline) was associated with older age, male sex, higher baseline CD4+ cell count and zidovudine-containing initial regimen. Factors associated with poor CD4+ cell count recovery to reach the level >500 cells/mm3 included older age, male sex and lower baseline CD4+ cell count. Conclusions CD4+ cell count failed to recover in a substantial proportion of adults initiating ART in this resource-limited setting. Older age, male sex and baseline CD4+ cell count are the dominant factors for poor CD4+ cell count recovery. Novel therapeutic approaches are needed focusing on high risk patients to maximize CD4+ cell count recovery and improve outcomes during therapy.
