Abstract
Chronic inflammation and T cell dysregulation persist in individuals infected with human immunodeficiency virus type 1 (HIV-1), even after successful antiretroviral treatment. The mechanism involved is not fully understood. Here, we used Olink proteomics to comprehensively analyze the aberrant inflammation-related proteins (IRPs) in chronic HIV-1-infected individuals, including in 24 treatment-naïve individuals, 33 immunological responders, and 38 immunological non-responders. T cell dysfunction was evaluated as T cell exhaustion, activation, and differentiation using flow cytometry. We identified a cluster of IRPs (cluster 7), including CXCL11, CXCL9, TNF, CXCL10, and IL18, which was closely associated with T cell dysregulation during chronic HIV-1 infection. Interestingly, IRPs in cluster 5, including ST1A1, CASP8, SIRT2, AXIN1, STAMBP, CD40, and IL7, were negatively correlated with the HIV-1 reservoir size. We also identified a combination of CDCP1, CXCL11, CST5, SLAMF1, TRANCE, and CD5, which may be useful for distinguishing immunological responders and immunological non-responders. In conclusion, the distinct inflammatory milieu is closely associated with immune restoration of T cells, and our results provide insight into immune dysregulation during chronic HIV-1 infection.

Abstract
Hepatitis C virus (HCV) infection is common among people living with HIV. HIV and HCV coinfected patients have higher overall mortality rates compared with HIV mono-infected patients. With its high cure rate of HCV infection, direct-acting antiviral (DAA) treatment provides an opportunity to improve the survival of the HIV/HCV coinfected population. The objective of this study is to investigate the association between DAA treatment and all-cause mortality among HIV/HCV coinfected people. The study included 7103 Medicare beneficiaries in the United States who were infected with both HIV and HCV between 2014 and 2017. Cox proportional hazards regression model was used to estimate adjusted hazard ratios (aHRs) of death for patients with and without DAA treatment while controlling for patient characteristics. During the study period, 1675 patients initiated DAA treatment (23.6%). The adjusted hazard ratio (aHR) of all-cause mortality between patients with and without DAA treatment was 0.37 (95% CI, 0.29-0.48), regardless of cirrhosis status. DAA treatment was associated with a smaller reduction in all-cause mortality for females (aHR, 0.50 [95% CI, 0.30-0.85]) compared with males (aHR, 0.34 [95% CI, 0.25-0.46]). DAA treatment was associated with improved survival among all HIV/HCV coinfected patients regardless of sex or HCV disease progression.

Front Immunol 2021; 12:753044. [PMID: 34887859 PMCID: PMC8650117 DOI: 10.3389/fimmu.2021.753044] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 11/02/2021] [Indexed: 12/12/2022] Open
Abstract
Background Approximately 10–40% of people with human immunodeficiency virus (HIV) infection are unable to obtain successful improvements in immune function after antiretroviral therapy (ART). These patients are at greater risk of developing non-acquired immunodeficiency syndrome (AIDS)-related conditions, with the accompanying increased morbidity and mortality. Discovering predictive biomarkers can help to identify patients with a poor immune response earlier and provide new insights into the mechanisms of this condition. Methods A total of 307 people with HIV were enrolled, including 110 immune non-responders (INRs) and 197 immune responders (IRs). Plasma samples were taken before ART, and quantities of plasma microRNAs (miRNAs) were determined using reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR). Candidate biomarkers were established through four phases: discovery, training, validation, and blinded test. Binary logistic regression was used to analyze the combined predictive capacity of the identified miRNAs. The effect of one miRNA, miR-16-5p, on T cell function was assessed in vitro. Results Expression of five miRNAs (miR-580, miR-627, miR-138-5p, miR-16-5p, and miR-323-3p) was upregulated in the plasma of INRs compared with that in IRs. Expression of these miRNAs was negatively correlated with both CD4+ T cell counts and the increase in the proportion of CD4+ T cells after one year of ART. These five miRNAs were combined in a predictive model, which could effectively identify INRs or IRs. Furthermore, we found that miR-16-5p inhibits CD4+ T cell proliferation by regulating calcium flux. Conclusion We established a five-miRNA panel in plasma that accurately predicts poor immune response after ART, which could inform strategies to reduce the incidence of this phenomenon and improve the clinical management of these patients.

Abstract
BACKGROUND Integrase strand transfer inhibitor (InSTI)-based regimens have become the major first-line treatment for HIV-1-infected patients in Taiwan. Transmitted drug resistance (TDR) and several clinical characteristics are associated with time to virological failure or viral suppression; however, these have not been investigated in Taiwan. OBJECTIVES To determine the impact of several factors on treatment outcomes in HIV-1-infected patients in Taiwan. METHODS The cohort included 164 HIV-1 treatment-naive patients in Taiwan from 2018 to 2020. Blood specimens were collected to determine the genotypic drug resistance using the Stanford University HIV drug resistance database. Cox proportional hazards models were used to identify factors associated with time to virological failure or viral suppression. RESULTS The prevalence of TDR in Taiwan was 27.4% and an increasing trend was seen from 2018 to 2020. TDR mutations related to NNRTIs were the most prevalent (21%) while TDR to InSTIs remained at a relatively low level (1.3%). A baseline HIV-1 viral load of ≥100 000 copies/mL was associated with a shorter time to virological failure [multivariate hazard ratio (mHR) 7.84; P = 0.018] and longer time to viral suppression (mHR 0.46; P < 0.001). Time to viral suppression was shorter in patients receiving InSTI-based regimens (mHR 2.18; P = 0.006). Different InSTI-based regimens as initial treatment did not affect the treatment outcomes. CONCLUSIONS This study found an increasing trend of HIV-1 TDR prevalence from 2018 to 2020 in Taiwan. Baseline HIV-1 viral load and receiving InSTI-based regimens are important factors associated with time to virological failure or viral suppression.

Effect of Traditional Chinese Medicine Therapy on the Trend in CD4 + T-Cell Counts among Patients with HIV/AIDS Treated with Antiretroviral Therapy: A Retrospective Cohort Study. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:5576612. [PMID: 34326884 PMCID: PMC8302365 DOI: 10.1155/2021/5576612] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 07/06/2021] [Indexed: 01/05/2023]
Abstract
This retrospective cohort study was conducted to explore the effect of traditional Chinese medicine (TCM) therapy on the long-term trends in CD4+ T-cell count among patients with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) who were treated with combined antiretroviral therapy (cART) over a 14-year period. A total of 721 individuals were treated with cART alone (cART group), and 307 individuals were treated with both cART and TCM (TCM + cART group). Among all enrolled patients with HIV/AIDS, 99.5% were farmers, 71.1% had more than 6 years of education, and 96.8% were infected with HIV via a paid blood donation. For those patients with HIV/AIDS who had a baseline CD4+ T-cell count of <350 cells/mL, the CD4+ T-cell count tended to increase to approximately 350 cells/mL more rapidly in the TCM + cART group than in the cART group, but when the baseline CD4+ T-cell count was ≥350 cells/mL, there was no difference between the cART and TCM + cART groups. For other patients with HIV/AIDS who had a baseline CD4+ T-cell count of 350–500 cells/mL, the CD4+ T-cell counts tended to increase slightly, but there was no difference between the two groups. For patients with HIV/AIDS who had a baseline CD4+ T-cell count of ≥500 cells/mL, the CD4+ T-cell counts tended to be maintained at a particular level, with no difference between the two groups. The results show that the effect of TCM on the CD4+ T-cell counts of patients with HIV/AIDS is related to the CD4+ T-cell level at the time of initial treatment. TCM can increase the CD4+ T-cell count among patients with HIV/AIDS who have a baseline CD4+ T-cell count of <350 cells/mL. Sex and age have a slight influence on the therapeutic effect of TCM.

Abstract
OBJECTIVES Gender differences in the efficacy of treatment and the mortality of HIV-infected patients have not yet been fully elucidated. For the first time, we used data from a 20-year cohort of people living with HIV (PLWH) in four provinces (Fars, Bushehr, Bandar Abbas, and Kohgiluyeh and Boyer-Ahmad) in the southern part of Iran to assess the gender difference in all-cause mortality in PLWH in Iran. METHODS We analysed data for 1216 patients aged ≥ 15 years who were diagnosed with HIV/AIDS between 1997 and 2017. Three hundred and fourteen (25.8%) were women. RESULTS The death rate from all causes among women was 13.7% vs. 43.8% among men (P < 0.001). All-cause mortality was significantly associated with gender [the adjusted hazard ratio (aHR) for men compared with women was 3.20], not being on antiretroviral therapy (ART) compared with being on ART at the last visit (aHR 5.42), older age (aHR 1.03), delayed HIV diagnosis compared with early diagnosis (aHR 1.72), history of incarceration (aHR 1.57), higher log CD4 count at diagnosis (aHR 0.54), and prophylaxis for Pneumocystis pneumonia (aHR 0.09). CONCLUSIONS The results of this 20-year cohort study suggest that gender is an important predictor of survival among HIV-infected patients. Improving early HIV diagnosis and early ART initiation in men, as well as increased access to hepatitis C virus treatment are needed to increase the survival rate of HIV-infected patients in Iran.

Very high baseline HIV viremia impairs efficacy of non-nucleoside reverse transcriptase inhibitor-based ART: a long-term observation in treatment-naïve patients. Infect Dis Poverty 2020; 9:75.

Abstract
BACKGROUND It is not completely clear whether a very high pre-therapy viral load (≥ 500 000 copies/ml) can impair the virological response. The aim of this study was to examine the influence of very high baseline HIV-RNA levels on long-term virological responses under one type of regimen. METHODS A retrospective study was performed based on data from two multicenter cohorts in China from January to November 2009, and from May 2013 to December 2015. Untreated HIV infected adults between 18 and 65 years old were recruited before receiving non-nucleoside reverse transcriptase inhibitor-based regimen. All patients had baseline HIV-RNA levels over 500 copies/ml, good adherence, and were followed for at least 24 weeks. Virological suppression was defined as the first HIV-RNA < 50 copies/ml. Virological failure was defined as any of incomplete viral suppression (HIV-RNA ≥ 200 copies/ml without virological suppression within 24 weeks of treatment) and viral rebound (confirmed HIV-RNA level ≥ 50 copies/ml after virological suppression). Chi-square test, Kaplan-Meier analysis, Cox proportional hazards model and Logistic regression were used to compare virological response between each pretreated viral load stratum. RESULTS A total of 758 treatment-naïve HIV patients in China were enlisted. Median follow-up time (IQR) was 144 (108-276) weeks. By week 48, rates of virological suppression in three groups (< 100 000, 100 000-500 000 and ≥ 500 000 copies/ml) were 94.1, 85.0, and 63.8%, respectively (P < 0.001). Very high baseline HIV viremia over 500 000 copies/ml were found to be associated with delayed virological suppression (≥ 500 000 vs < 100 000, adjusted relative hazard = 0.455, 95% CI: 0.32-0.65; P < 0.001) as well as incomplete viral suppression (≥ 500 000 vs < 100 000, adjusted odds ratio [aOR] = 6.084, 95% CI: 2.761-13.407; P < 0.001) and viral rebound (≥ 50 000 vs < 100 000, aOR = 3.671, 95% CI: 1.009-13.355, P = 0.048). CONCLUSIONS Very high levels of pre-treatment HIV-RNA were related with delayed efficacy of NNRTI-based ART and increased risk of treatment failure. More potent initial regimens should be considered for those with this clinical character.

Abstract
The morbidity and mortality of HIV type-1 (HIV-1)-related diseases were dramatically diminished by the grounds of the introduction of potent antiretroviral therapy, which induces persistent suppression of HIV-1 replication and gradual recovery of CD4+ T-cell counts. However, ∼10-40% of HIV-1-infected individuals fail to achieve normalization of CD4+ T-cell counts despite persistent virological suppression. These patients are referred to as "inadequate immunological responders," "immunodiscordant responders," or "immunological non-responders (INRs)" who show severe immunological dysfunction. Indeed, INRs are at an increased risk of clinical progression to AIDS and non-AIDS events and present higher rates of mortality than HIV-1-infected individuals with adequate immune reconstitution. To date, the underlying mechanism of incomplete immune reconstitution in HIV-1-infected patients has not been fully elucidated. In light of this limitation, it is of substantial practical significance to deeply understand the mechanism of immune reconstitution and design effective individualized treatment strategies. Therefore, in this review, we aim to highlight the mechanism and risk factors of incomplete immune reconstitution and strategies to intervene.

The syndemic effect of HIV/HCV co-infection and mental health disorders on acute care hospitalization rate among people living with HIV/AIDS: a population-based retrospective cohort study. Canadian Journal of Public Health 2019; 110:779-791. [PMID: 31441005 DOI: 10.17269/s41997-019-00253-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/14/2018] [Accepted: 07/25/2019] [Indexed: 12/14/2022]
Abstract
OBJECTIVE Our primary objective was to examine the syndemic effect of HIV/HCV co-infection and mental health disorders (MHD) on the acute care hospitalization rate among people living with HIV (PLW-HIV) in British Columbia, Canada. Secondarily, we aimed to characterize the longitudinal trends in the aforementioned rate, while controlling for the effect of several factors. METHODS In this retrospective cohort study, individuals were antiretroviral therapy-naïve, ≥ 18 years old, initiated treatment between 1 January 2000 and 31 December 2014, and were followed for at least 6 months until 31 December 2015 or last contact. The outcome was acute care hospitalization rate (every 6-month interval) per individual. The exposure was the interaction between HIV/HCV co-infection and MHD. Generalized non-linear mixed-effects models were built. RESULTS Of the 4046 individuals in the final analytical sample, 1597 (39%) were PLW-HIV without MHD, 606 (15%) were people living with HIV and HCV (PLW-HIV/HCV) without MHD, 988 (24%) were PLW-HIV with MHD, and 855 (21%) were PLW-HIV/HCV with MHD. The adjusted rate ratios for acute care hospitalizations were 1.31 (95% [confidence interval] 1.13-1.52), 2.01 (95% CI 1.71-2.36), and 2.53 (95% CI 2.20-2.92) for PLW-HIV with MHD, PLW-HIV/HCV without MHD, and PLW-HIV/HCV with MHD, respectively, relative to PLW-HIV without MHD. CONCLUSION The HIV/HCV co-infection and MHD interaction demonstrated a significant effect on the rate of acute care hospitalization, particularly for PLW-HIV/HCV with MHD. Implementing widely accessible integrative care model best practices may address this public health challenge.

Abstract
Increase of peripheral blood CD4 lymphocyte counts is a key goal of combined antiretroviral therapy (cART); most, but not all, recipients respond adequately and promptly. A small number of studies have examined specific genetic factors associated with the extent of CD4 recovery. We report a genome-wide examination of factors that predict CD4 recovery in HIV-infected women. We identified women in in a cohort study who were on cART with viral load below 400 copies, and drew racially and ethnically matched samples of those with good CD4 response over 2 years or poor response. We analyzed the exomes of those women employing next generation sequencing for genes associated with CD4 recovery after controlling for non-genetic factors identified through forward stepwise selection as important. We studied 48 women with good CD4 recovery and 42 with poor CD4 recovery during virologically-suppressive cART. Stepwise logistic regression selected only age as a statistically significant (p<0.05) non-genetic predictor of response type (each additional year of age reduced the odds of good recovery by 11% (OR = 0.89, CI = 0.84–0.96, p = 0.0009). After adjustment for age and genomic estimates of race and ethnicity, 41 genes harbored variations associated with CD4 recovery group (p≤0.001); 5 of these have been previously reported to be associated with HIV infection, 4 genes would likely influence CD4 homeostasis, and 13 genes either had known functions or were members of product families that had functions for which interactions with HIV or effects on lymphocyte homeostasis were biologically plausible. Greater age was the strongest acquired factor that predicted poor CD4 cell recovery. Sequence variations spanning 41 genes were independently predictive of CD4 recovery. Many of these genes have functions that impact the cell cycle, apoptosis, lymphocyte migration, or have known interactions with HIV. These findings may help inform new hypotheses related to responses to HIV therapy and CD4 lymphocyte homeostasis.

Abstract
Although HIV diagnoses among women have declined in recent years in the United States (U.S.), women accounted for 19% of new HIV diagnoses in 2016. In addition, women comprise 24% of the 973,846 persons living with HIV infection in the U.S. However, HIV prevention interventions targeting women are limited. We performed a review on HIV infection in women to increase awareness, improve overall care, and inform intervention development. A systematic literature review was conducted using literature published in PubMed, PsychINFO (EBSCO), and Scopus from July 2000 and June 2017. We included studies that: (1) were conducted in the U.S., (2) enrolled at least 50 HIV-positive women, and (3) utilized a case-control, cohort, or surveillance study design. Of 7497 articles, 48 articles met inclusion criteria. HIV diagnoses among women declined 32% between 2001 and 2016. In 2016, 61% of diagnoses in women were among African American women, and 56% were in the South. Women reported barriers to HIV care largely due to psychosocial challenges and social/structural determinants of health (SDH) barriers. Though new diagnoses among women have declined, racial and regional disparities remain. HIV prevention and research efforts with women are vital to inform interventions and reduce disparities.

Clinical characteristics of HIV-1-infected patients with high levels of plasma interferon-γ: a multicenter observational study. BMC Infect Dis 2019; 19:11.

Abstract
Background Circulating interferon-γ (IFN-γ) concentration may be sustained at a high level regardless of the initiation of antiretroviral therapy (ART) in some patients with HIV-1 infection. In the present study, we examined the clinical characteristics of HIV-1-infected patients with high levels of plasma IFN-γ. Methods The study subjects were patients infected with HIV-1 who were either naïve to ART with CD4+ cell count > 200 cells/μL (n = 12), or had achieved viral suppression after ART for over a year (n = 188). The levels of plasma IFN-γ and interleukin-6 (IL-6) were measured by the enzyme-linked immunosorbent assay. Patients were divided into high IFN-γ and low IFN-γ groups based on a cutoff level of 5 pg/mL. Results The high IFN-γ group included 41 patients (21%). Compared to the patients on ART with low IFN-γ levels, those on ART in the high IFN-γ group were more likely to be younger than 50 years of age (P = 0.0051) and less likely to have dyslipidemia (P = 0.0476) or to be on a protease inhibitor (P = 0.0449). There was no significant difference between groups in the median increase of CD4+ cell counts from the initiation of ART for up to 3 years. However, after 4 years, the increase in CD4+ cell counts was significantly lower in the high IFN-γ group compared with that in the low IFN-γ group. There were no such significant differences between patients with low and high (> 2 pg/mL) levels of plasma IL-6. Conclusion We concluded that HIV-1-infected patients with high levels of circulating IFN-γ did not have a higher rate of comorbidities related to immune activation. However, they exhibited lower CD4+ cell count recovery after 4 years of being on ART. This deficit could be a consequence of persistent immune activation.

Abstract
We assessed the effect of co-infection by hepatitis C virus (HCV) on immunological and virological response at 48 weeks from initiation of antiretroviral therapy (ART).We included patients from the Cohort of Spanish HIV Research Network (CoRIS) starting ART between January 2004 and November 2014, had at least 1 CD4 T-cell count and viral load measurements both in the previous 6 months and at 48 (±12) weeks from ART initiation, and HCV serology before ART initiation. We used linear regression for mean differences in CD4 T-cell count increase from ART initiation and logistic regression to estimate odds ratios for virological response.Of 12,239 patients by November 30, 2015, 5070 met inclusion criteria: 4382 (86.4%) HIV mono-infected and 688 (13.6%) HIV/HCV co-infected. Co-infected patients were more likely to have acquired HIV through injecting drugs use (57.4% vs. 1.1%), to be women, older, and Spanish, have a lower educational level, and having started ART with lower CD4 counts and acquired immunodeficiency syndrome. CD4 T-cell count increase at 48 weeks was 229.7 cell/μL in HIV-monoinfected and 161.9 cell/μL in HIV/HCV-coinfected patients. The percentages of patients achieving a virological response at 48 weeks were 87.0% and 78.3% in mono and coinfected patients, respectively. Multivariable analyses showed that at 48 weeks, coinfected patients increased 44.5 (95% confidence interval [CI]: 24.8-64.3) cells/μL less than monoinfected and had lower probability of virological response (odds ratio: 0.62; 95% CI: 0.44-0.88).HIV/HCV-coinfected patients have lower immunological and virological responses at 48 weeks from ART initiation than monoinfected patients.

Abstract
OBJECTIVES One in four persons living with HIV is coinfected with hepatitis C virus (HCV). Biological and behavioral mechanisms may increase HIV viral load among coinfected persons. Therefore, we estimated the longitudinal effect of chronic HCV on HIV suppression after ART initiation among women with HIV (WWH). DESIGN HIV RNA was measured every 6 months among 441 WWH in the Women's Interagency HIV Study who initiated ART from 2000 to 2015. METHODS Log-binomial regression models were used to compare the proportion of study visits with detectable HIV RNA between women with and without chronic HCV. Robust sandwich variance estimators accounted for within-person correlation induced by repeated HIV RNA measurements during follow-up. We controlled for confounding and selection bias (because of loss to follow-up and death) using inverse probability-of-exposure-and-censoring weights. RESULTS One hundred and fourteen women (25%) had chronic HCV before ART initiation. Overall, the proportion of visits with detectable HIV RNA was similar among women with and without chronic HCV [relative risk (RR) 1.19 (95% CI 0.72, 1.95)]. Six months after ART initiation, the proportion of visits with detectable HIV RNA among women with chronic HCV was 1.88 (95% CI 1.41-2.51) times that among women without HCV, at 2 years, the ratio was 1.60 (95% CI 1.17-2.19), and by 6 years there was no difference (1.03; 95% CI 0.60-1.79). CONCLUSION Chronic HCV may negatively impact early HIV viral response to ART. These findings reaffirm the need to test persons with HIV for HCV infection, and increase engagement in HIV care and access to HCV treatment among persons with HIV/HCV coinfection.

Abstract
INTRODUCTION Achieving viral suppression is key in the global strategy to end the HIV epidemic. However, the levels of viral suppression have yet to be described in many resource-limited settings. METHODS We investigated the time to virologic failure (VF; defined as a viral load of ≥1000 copies/ml) and changes in CD4 counts since starting antiretroviral therapy (ART) in a cohort of HIV-infected adults in Hanoi, Vietnam. Factors related to the time to VF and impaired early immune recovery (defined as not attaining an increase in 100 cells/mm3 in CD4 counts at 24 months) were further analysed. RESULTS From 1806 participants, 225 were identified as having VF at a median of 50 months of first-line ART. The viral suppression rate at 12 months was 95.5% and survival without VF was maintained above 90% until 42 months. An increase in CD4 counts from the baseline was greater in groups with lower baseline CD4 counts. A younger age (multivariate hazard ratio (HR) 0.75, vs. <30), hepatitis C (HCV)-antibody positivity (HR 1.43), and stavudine (d4T)-containing regimens (HR 1.4, vs. zidovudine (AZT)) were associated with earlier VF. Factors associated with impaired early immune recovery included the male sex (odds ratio (OR) 1.78), HCV-antibody positivity (OR 1.72), d4T-based regimens (OR 0.51, vs. AZT), and nevirapine-based regimens (OR 0.53, vs. efavirenz) after controlling for baseline CD4 counts. CONCLUSION Durable high-rate viral suppression was observed in the cohort of patients on first-line ART in Vietnam. Our results highlight the need to increase adherence support among injection drug users and HCV co-infected patients.

Abstract
Co-infection with hepatitis B (HBV) and C (HCV) is common among people living with HIV (PLHIV). This study investigates the impacts of hepatitis co-infection on antiretroviral therapy (ART) outcomes and hepatotoxicity in PLHIV. The cohort study included 1984 PLHIV. Hepatotoxicity was defined by elevated alanine aminotransferase (ALT) levels. ART outcomes were measured by CD4 cell counts, viral load, and mortality rate in patients. Among 1984 PLHIV, 184 (9.3%) were co-infected with HBV and 198 (10.0%) with HCV and 54 (2.7%) were co-infected with HBV and HCV. Of these patients, 156 (7.9%) had ALT elevation ≥ grade 1 at baseline. During the course of ART, the mortality rate and its adjusted hazard ratio (AHR) in PLHIV who were co-infected with HCV (2.6/100 person-years [py], AHR = 2.3, 95%CI 1.1-4.7) was higher than for patients with mono-infected HIV, as it was for those with an elevated ALT (4.4/100 py, AHR = 3.8, [1.7-8.2]) at baseline compared to those with normal ALT. After 6-12 months of ART, the incidence of hepatotoxicity among all the patients was 3.7/100 py. The risk of hepatotoxicity was higher in HCV co-infected (18.6/100 py, adjusted odds ratio [AOR] = 12.4, [8.1-18.2]) than HIV mono-infected patients, and for all regimens (nevirapine: 30.0/100 py, 34.2, 7.3-47.9; zidovudine/stavudine: 24.7/100 py, 22.1, 7.1-25.5; efavirenz: 14.5/100 py, 9.4, 3.5-19.2; lopinavir/ritonavir: 40.1/100 py, 52.2, 9.5-88.2) except tenofovir (4.3/100 py, 4.9, 0.8-9.5). Patients with HBV/HCV co-infected had high hepatotoxicity (10.0/100 py, 6.3, 1.2-23.3) over the same period. Patients with HCV co-infection and HBV/HCV co-infection demonstrated higher hepatotoxicity rate compared with HIV mono-infected patients in China.

Narrowing the Gap in Life Expectancy Between HIV-Infected and HIV-Uninfected Individuals With Access to Care. J Acquir Immune Defic Syndr 2017; 73:39-46. [PMID: 27028501 DOI: 10.1097/qai.0000000000001014] [Citation(s) in RCA: 284] [Impact Index Per Article: 40.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/17/2023]
Abstract
BACKGROUND It is unknown if a survival gap remains between HIV-infected and HIV-uninfected individuals with access to care. METHODS We conducted a cohort study within Kaiser Permanente California during 1996-2011, using abridged life tables to estimate the expected years of life remaining ("life expectancy") at age 20. RESULTS Among 24,768 HIV-infected and 257,600 HIV-uninfected individuals, there were 2229 and 4970 deaths, with mortality rates of 1827 and 326 per 100,000 person-years, respectively. In 1996-1997, life expectancies at age 20 for HIV-infected and HIV-uninfected individuals were 19.1 and 63.4 years, respectively, corresponding with a gap of 44.3 years (95% confidence interval: 38.4 to 50.2). Life expectancy at age 20 for HIV-infected individuals increased to 47.1 years in 2008 and 53.1 years by 2011, narrowing the gap to 11.8 years (8.9-14.8 years) in 2011. In 2008-2011, life expectancies at age 20 for HIV-infected individuals ranged from a low of 45.8 years for blacks and 46.0 years for those with a history of injection drug use to a high of 52.2 years for Hispanics. HIV-infected individuals who initiated antiretroviral therapy with CD4 ≥500 cells per microliter had a life expectancy at age 20 of 54.5 years in 2008-2011, narrowing the gap relative to HIV-uninfected individuals to 7.9 years (5.1-10.6 years). For these HIV-infected individuals, the gap narrowed further in subgroups with no history of hepatitis B or C infection, smoking, drug/alcohol abuse, or any of these risk factors. CONCLUSIONS Even with early treatment and access to care, an 8-year gap in life expectancy remains for HIV-infected compared with HIV-uninfected individuals.

Abstract
BACKGROUND The effect of hepatitis C virus (HCV) coinfection on CD4 T cell recovery in treated HIV-infected children is poorly understood. OBJECTIVE To compare CD4 T cell recovery in HIV/HCV coinfected children with recovery in HIV monoinfected children. METHOD We studied 355 HIV monoinfected and 46 HIV/HCV coinfected children receiving antiretroviral therapy (ART) during a median follow-up period of 4.2 years (interquartile range: 2.7-5.3 years). Our dataset came from the Ukraine pediatric HIV Cohort and the HIV/HCV coinfection study within the European Pregnancy and Paediatric HIV Cohort Collaboration. We fitted an asymptotic nonlinear mixed-effects model of CD4 T cell reconstitution to age-standardized CD4 counts in all 401 children and investigated factors predicting the speed and extent of recovery. RESULTS We found no significant impact of HCV coinfection on either pre-ART or long-term age-adjusted CD4 counts (z scores). However, the rate of increase in CD4 z score was slower in HIV/HCV coinfected children when compared with their monoinfected counterparts (P < 0.001). Both monoinfected and coinfected children starting ART at younger ages had higher pre-ART (P < 0.001) and long-term (P < 0.001) CD4 z scores than those who started when they were older. CONCLUSIONS HIV/HCV coinfected children receiving ART had slower CD4 T cell recovery than HIV monoinfected children. HIV/HCV coinfection had no impact on pre-ART or long-term CD4 z scores. Early treatment of HIV/HCV coinfected children with ART should be encouraged.

Abstract
BACKGROUND The risk of tuberculosis (TB) is greater for individuals with human immunodeficiency virus (HIV) who are on combined antiretroviral therapy (c-ART) than for the normal population. Therefore, the detection and treatment of latent tuberculosis infections is recommended for all HIV-positive persons with positive tuberculin skin tests (TSTs). MATERIALS AND METHODS This retrospective cohort study included all HIV-positive individuals with CD4 lymphocyte counts greater than 200 cells/μL and negative TST results, who were taking antiretroviral drugs and had been referred to Imam Khomeini Teaching Hospital Consultation Centre for Clients with Risky Behaviors in Tehran, Iran, from 2008 to 2013. TST conversion to positivity is defined as an induration increase of at least 5 mm compared with a previously negative TST result within a 1-year period. Conversion rates are expressed in person-years of observation. RESULTS A total of 113 patients were included in our study. At 1 year, 9 of the 113 TST-negative patients taking c-ART became TST-positive (8%; 8 males and 1 female). The TST conversion incidence rate was 10.09/100 person-years. TST conversion was only found to be associated with sex (odds ratio: 8.64; 95% confidence interval: 1.04-7.56, p = 0.032). CONCLUSION Our results suggest that TSTs should be administered to all HIV-positive patients before beginning isoniazid preventive therapy in Iran.

Gaps in the Continuum of HIV Care: Long Pretreatment Waiting Time between HIV Diagnosis and Antiretroviral Therapy Initiation Leads to Poor Treatment Adherence and Outcomes. BIOMED RESEARCH INTERNATIONAL 2016; 2016:2648923. [PMID: 28101505 PMCID: PMC5214466 DOI: 10.1155/2016/2648923] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/31/2016] [Revised: 11/25/2016] [Accepted: 12/07/2016] [Indexed: 12/15/2022]
Abstract
Background. Criteria for antiretroviral treatment (ART) were adjusted to enable early HIV treatment for people living HIV/AIDS (PLHIV) in China in recent years. This study aims to determine how pretreatment waiting time after HIV confirmation affects subsequent adherence and outcomes over the course of treatment. Methods. A retrospective observational cohort study was conducted using treatment data from PLHIV in Yuxi, China, between January 2004 and December 2015. Results. Of 1,663 participants, 348 were delayed testers and mostly initiated treatment within 28 days. In comparison, 1,315 were nondelayed testers and the median pretreatment waiting time was 599 days, but it significantly declined over the study period. Pretreatment CD4 T-cell count drop (every 100 cells/mm3) contributed slowly in CD4 recovery after treatment initiation (8% less, P < 0.01) and increased the risk of poor treatment adherence by 15% (ARR = 1.15, 1.08–1.25). Every 100 days of extensive pretreatment waiting time increased rates of loss to follow-up by 20% (ARR = 1.20, 1.07–1.29) and mortality rate by 11% (ARR = 1.11, 1.06–1.21), based on multivariable Cox regression. Conclusion. Long pretreatment waiting time in PLHIV can lead to higher risk of poor treatment adherence and HIV-related mortality. Current treatment guidelines should be updated to provide ART promptly.

CD4 Count Recovery After Initiation of Antiretroviral Therapy in Patients Infected With Human Immunodeficiency Virus. Am J Med Sci 2016; 352:239-44. [PMID: 27650226 DOI: 10.1016/j.amjms.2016.05.032] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2016] [Revised: 05/13/2016] [Accepted: 05/31/2016] [Indexed: 01/03/2023]
Abstract
BACKGROUND Prognosis for patients infected with human immunodeficiency virus (HIV) correlates with levels of CD4+ T cells. Initiation of antiretroviral therapy (ART) interrupts multiple points in the virus life cycle, causing an increase in CD4 cells. The rate at which the CD4 count recovers is highly variable and subject to influence by many factors. METHODS We performed a deidentified data review to determine factors influencing the rate of CD4 count recovery after ART initiation. The associations between the changes in CD4 count from baseline at 5 time points, and factors including age, race, weight, baseline CD4 count, baseline viral load, specific ART medications and various comorbidities, were evaluated with univariate and multivariate analyses, using t-test, analysis of variance and multiple regressions. RESULTS CD4 count continued to rise even up to 10 years after ART initiation, with the steepest increase in the first 3 months. High baseline viral load and low baseline CD4 count had the most consistent positive influence on CD4 count recovery rate across the 5 measured time points. Other factors that were significantly positively associated with CD4 recovery rate included younger baseline age, higher baseline weight and female gender. CONCLUSIONS CD4 counts in HIV positive patients who consistently take ART continue to increase out to at least 10 years. Patients with a more advanced HIV infection at baseline, as indicated by high viral loads or low CD4 counts, have a greater rate of CD4 count recovery after starting ART, possibly because their CD4 counts have more room for improvement.

Abstract
We examined the longitudinal association between alcohol use and liver fibrosis, measured by FIB-4 Score, among HIV-infected individuals by (1) antiretroviral therapy (ART) class, and (2) the presence of hepatitis C (HCV) co-infection. This was a prospective cohort study of 550 individuals in the Johns Hopkins HIV Clinical Cohort initiating ART between 2000 and 2012. The relationship between alcohol consumption (defined using NIAAA categories of non-, moderate, and hazardous drinkers) and liver fibrosis (FIB-4 score) by ART class was assessed using linear mixed effects models. Additionally, we examined whether the presence of HCV modified and whether viral load mediated the relationship between alcohol use and liver fibrosis. Overall, FIB-4 levels were 15.6% higher in hazardous drinkers compared to moderate drinkers (p = 0.025) after adjusting by age, sex, and race. Hazardous drinkers on PI-based regimens had FIB-4 scores 26.9% higher than moderate drinkers (p = 0.015). However, there was no difference in FIB-4 levels between hazardous drinkers on non-PI-based regimens compared to moderate drinkers (1.83% versus moderate drinkers, p = 0.848). There was no significant difference in FIB-4 between nondrinkers and moderate drinkers, irrespective of ART regimen. These associations were not modified by HCV status or mediated by viral load changes. Individuals with hazardous alcohol consumption and on PI-based regimens had significantly increased liver fibrosis, as measured by the FIB-4. These data suggest that providers should consider level of alcohol consumption when choosing an ART regimen to minimize detrimental effects on the liver.

Abstract
OBJECTIVES The aim of the study was to study the factors associated with immunological recovery in HIV-infected patients with suppressed viral load. METHODS Nadir and current CD4 cell counts were recorded in 821 patients, as well as many demographic, epidemiological, lifestyle, clinical, therapeutic, genetic, laboratory, liver fibrosis and viral hepatitis parameters. RESULTS The median age of the patients was 44.4 years [interquartile range (IQR) 40.3-48.0 years], the median time since HIV diagnosis was 15.3 years (IQR 10.5-18.9 years), the median time of suppressed viral load was 7.0 years (IQR 4.0-10.0 years) and the median time on the current antiretroviral regimen was 2.8 years (IQR 1.4-4.7 years). The median nadir and current CD4 counts were 193.0 (IQR 84.0-301.0) and 522.0 (IQR 361.0-760) cells/μL, respectively, separated by a median period of 10.2 years (IQR 5.9-12.9 years). The median CD4 count gain during follow-up was 317.0 (IQR 173.0-508.0) cells/μL. Many variables were associated with CD4 cell gains in univariate analyses, including age, gender, epidemiology, prior clinical conditions, fibrosis stage, transient elastometry, aspartate aminotransferase (AST), nadir CD4 count and hepatitis B and C virus infections and genotypes, as well as the durations of follow-up since nadir CD4 count, overall antiretroviral treatment, current antiretroviral regimen, protease inhibitor therapy and suppression of viral load. Multivariate analysis revealed that longer duration of HIV suppression (P < 0.0001), more advanced clinical Centers for Disease Control and Prevention (CDC) stages (P < 0.0001), younger age (P = 0.0003), hepatitis C virus genotypes 1 and 4 (P = 0.003), sexual acquisition of HIV (P = 0.004), and lower transient elastometry values (P = 0.03) were independent predictors of CD4 cell gains. Overall, the model accounted for 14.2% of the variability in CD4 count. CONCLUSIONS In addition to the duration of HIV suppression, HIV-related diseases, HIV epidemiology, age, hepatitis C virus genotypes, and liver fibrosis were independently associated with long-term immunological recovery.
