HCV-Related Mortality Among HIV/HCV Co-infected Patients: The Importance of Behaviors in the HCV Cure Era (ANRS CO13 HEPAVIH Cohort)
2020
Mortality among individuals co-infected with HIV and hepatitis C virus (HCV) is relatively high. We evaluated the association between psychoactive substance use and both HCV and non-HCV mortality in HIV/HCV co-infected patients in France, using Fine and Gray’s competing-risk model adjusted for socio-demographic, clinical predictors and confounding factors, while accounting for competing causes of death. Over a 5-year median follow-up period, 77 deaths occurred among 1028 patients. Regular/daily cannabis use, elevated coffee intake, and not currently smoking were independently associated with reduced HCV-mortality (adjusted sub-hazard ratio [95% CI] 0.28 [0.10–0.83], 0.38 [0.15–0.95], and 0.28 [0.10–0.79], respectively). Obesity and severe thinness were associated with increased HCV-mortality (2.44 [1.00–5.93] and 7.25 [2.22–23.6] versus normal weight, respectively). Regular binge drinking was associated with increased non-HCV-mortality (2.19 [1.10–4.37]). Further research is needed to understand the causal mechanisms involved. People living with HIV/HCV co-infection should be referred for tobacco, alcohol and weight control interventions and potential benefits of cannabis-based therapies investigated.

Anti-Retroviral Agents - therapeutic use

Background
Hepatitis B is a major concern in Africa, especially in HIV-infected patients. Unfortunately, access to hepatitis B virus (HBV) testing and adequate treatment remains a challenge in the continent. We investigated HBV testing, treatment, and virologic suppression in HIV-infected patients followed up as part of Cameroon’s national antiretroviral programme.
Methods
A cross-sectional survey was performed in adult patients receiving antiretroviral therapy (ART) in 19 hospitals in the Centre and Littoral regions in Cameroon. The proportions of patients tested for hepatitis B surface antigen (HBsAg) prior to the study were compared among all study hospitals using the Chi-square test. The association of individual and hospital-related characteristics with HBV testing and virologic suppression was assessed using multilevel logistic regression models.
Results
Of 1706 patients (women 74%, median age 42 years, median time on ART 3.9 years), 302 (17.7%) had been tested for HBsAg prior to the study. The proportion of HBV-tested patients ranged from 0.8 to 72.5% according to the individual hospital (
p
< 0.001). HBV testing was lower in women (adjusted odds ratio [aOR] 0.64, 95% confidence interval [CI] 0.46–0.89,
p
= 0.010) and higher in patients who initiated ART in 2010 or later (aOR 1.66, 95% CI 1.23–2.27,
p
< 0.001). Of 159 HBsAg-positive patients at the time of the study (9.3%), only 97 (61.0%) received Tenofovir + Lamivudine (or Emtricitabine). Of 157 coinfected patients, 114 (72.6%) had a HBV viral load < 10 IU/mL. HBV suppression was higher in patients with a HIV viral load < 300 copies/mL (aOR 3.46, 95% CI 1.48–8.09,
p =
0.004) and lower in patients with increased ALT level (aOR 0.86 per 10 IU/mL increase, 95% CI 0.75–0.97,
p
= 0.019).
Conclusions
A substantial proportion of HIV/HBV coinfected patients were at higher risk of liver disease progression. Improving the management of HBV infection in the routine healthcare setting in Africa is urgently required in order to achieve the 2030 elimination targets. Micro-elimination of HBV infection in people living with HIV could be an easier and cost-effective component than more widely scaling up HBV policies.

Introduction Daily pre‐exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) is associated with a small but statistically significant decrease in estimated glomerular filtration rate (eGFR). We assessed the renal safety of on‐demand PrEP with TDF/FTC in HIV‐1 uninfected men. Methods We used data from the randomized double‐blind placebo‐controlled ANRS‐IPERGAY trial and its open‐label extension conducted between February 2012 and June 2016 among HIV‐uninfected MSM starting on‐demand PrEP. Using linear mixed model, we evaluated the mean eGFR decline from baseline over time and determined risks factors associated with eGFR decline during the study. Results During the blind phase, with a median follow‐up of 9.4 months, the mean decline slope of eGFR from baseline was −0.88 and −1.53 mL/min/1.73 m2 per year in the placebo (n = 201) and the TDF/FTC group (n = 198) respectively, with a slope difference of 0.65 mL/min/1.73 m2 per year (p = 0.27). Including both phases, 389 participants started on‐demand TDF/FTC with a median follow‐up of 19.2 months and a mean decline of eGFR from baseline of −1.14 mL/min/1.73 m2 per year (p < 0.001). The slope of eGFR reduction was not significantly different in participants with baseline eGFR ≤ 90 mL/min/1.73 m2 (p = 0.44), age >40 years (p = 0.24) or hypertension (p = 0.21). There was a dose‐response relationship between recent tenofovir exposure and lower eGFR when considering the number of pills taken in the two months prior the visit (eGFR difference of −0.88 mL/min/1.73 m2 between >15 pills/month vs. ≤15 pills/month, p < 0.01) or plasma tenofovir concentrations at the visit (eGFR difference compared to ≤2 ng/mL: >2 to ≤10ng/mL: −0.98 mL/min/1.73 m2, >10 to ≤40ng/mL: −1.28 mL/min/1.73 m2, >40 ng/mL: −1.82 mL/min/1.73 m2, p < 0.001). Three participants discontinued TDF/FTC for eGFR < 60 mL/min/1.73 m2 during the OLE phase. No case of Fanconi syndrome was reported. Conclusions The renal safety of on‐demand PrEP with TDF/FTC was good. The overall reduction and intermittent exposure to TDF/FTC may explain this good renal safety.

Background. Diabetes and insulin resistance (IR) is common in human immunodeficiency virus–hepatitis C virus (HIV–HCV)-coinfected patients, a population also concerned with elevated cannabis use. Cannabis has been associated with reduced IR risk in some population-based surveys. We determined whether cannabis use was consistently associated with reduced IR risk in HEPAVIH, a French nationwide cohort of HIV–HCV-coinfected patients. Methods. HEPAVIH medical and sociobehavioral data were collected (using annual self-administered questionnaires). We used 60 months of follow-up data for patients with at least 1 medical visit where IR (using homeostatic model assessment of insulin resistance [HOMA-IR]) and cannabis use were assessed. A mixed logistic regression model was used to evaluate the association between IR risk (HOMA-IR > 2.77) and cannabis use (occasional, regular, daily). Results. Among the 703 patients included in the study (1287 visits), 323 (46%) had HOMA-IR > 2.77 for at least 1 follow-up visit and 319 (45%) reported cannabis use in the 6 months before the first available visit. Cannabis users (irrespective of frequency) were less likely to have HOMA-IR > 2.77 (odds ratio [95% confidence interval], 0.4 [.2–.5]) after adjustment for known correlates/confounders. Two sensitivity analyses with HOMA-IR values as a continuous variable and a cutoff value of 3.8 confirmed the association between reduced IR risk and cannabis use. Conclusions. Cannabis use is associated with a lower IR risk in HIV–HCV-coinfected patients. The benefits of cannabis-based pharmacotherapies for patients concerned with increased risk of IR and diabetes need to be evaluated in clinical research and practice.

To estimate rates and identify correlates of HIV disclosure in migrants from sub-Saharan Africa (SSA) successfully treated, a sub-analysis was conducted in HIV-1 native SSA migrants, living in France with undetectable viral load on antiretroviral, included in the VIHVO adherence study. Logistic regression models assessed factors associated with HIV disclosure. Among 246 individuals (40 % male, median age 41), 79 % of those in a steady heterosexual partnership (n = 167) had disclosed their status to their partner, 55 % of the total 246 to a relative, and 33 % to (an)other person(s). Disclosure to one’s steady partner was associated with a follow-up duration since HIV diagnosis of more than 5 years, a higher literacy level, a better social context and marital status. Women were more likely to disclose their HIV status to relatives. Interventions targeting this population should be provided to improve disclosure which in turn ensures better social support, testing of the partner and lower rates of undiagnosed HIV.

Abstract Background To improve the effectiveness of public health policies, HPV vaccination campaigns target “high-risk groups”, such as men who have sex with men (MSM). In France, HPV vaccination is recommended for MSM up to the age of 26, rather than 19 for the general population. It’s crucial to assess the impact of such targeting policies on MSM who are eligible for HPV vaccination. Methods A qualitative study was conducted between April and July 2022 among MSM participating in the “Vaccigay” electronic survey in France (Brosset et al. 2023). Participants were selected based on age and declared HPV vaccination status. Semi-structured interviews were conducted by telephone using a thematic grid on the barriers and facilitators influencing the uptake of the vaccine against HPV. The interviews lasted on average 40 minutes. The audio-recorded verbatims were transcribed and thematically analysed using NVivo software. Results A total of 22 viewpoints were analysed. Two opinions emerged without differences in terms of individuals’ profile. The reasons MSM advocated for targeted sexual healthcare stemmed from the recognition of epidemiological factors, as well as the need for greater listening and understanding from healthcare workers. MSM who didn’t support targeted sexual healthcare did so because they felt stigmatised and because sexual orientation might not always be clear. Among them, some advocated for sexual healthcare based on sexual practices rather than sexual orientation. Others emphasized the necessity of extending prevention tools for sexual risks existing for MSM to the general population. Conclusions The findings of this study prompt reflection on universal versus targeted public health policies, as well as sexual and gender discrimination within the healthcare system. We recommend improving healthcare workers’ education on sexual healthcare, and that HPV vaccination guidelines could be extended to all adults up to 26, regardless of their sexual orientation. Key messages • Improving knowledge among healthcare workers and MSM about HPV and sexual health is important. • It is important to extend the age for the HPV vaccination, regardless of sexual orientation.

Factors associated with unprotected anal intercourse among men who have sex with men in Douala, Cameroon
2010
ObjectivesResearch on men who have sex with men (MSM) in sub-Saharan Africa was neglected for a long time. The objective of this study was to understand factors associated with unprotected anal intercourse (UAI) with male partners among a group of MSM living in the city of Douala, Cameroon.MethodsIn 2008, a survey on the sexual activity and practices of MSM was set up in Douala in collaboration with a local community-based organisation. Data were collected among a convenience sample of 168 MSM during face-to-face interviews with trained interviewers.ResultsA total of 142 individuals reported sexual activity during the previous 6 months, among whom 80 (57%) reported UAI with male partners. In a multivariate logistic regression model adjusted for the frequency of sexual intercourse, not having had access to prevention interventions and not knowing any HIV-infected person were both independently associated with a higher risk of UAI. Other factors associated with this higher risk included having had a stable male partnership at some point in one's life and not having been out of Douala for more than 4 weeks during the previous year.ConclusionsThis community-based research is the first study of MSM in Cameroon and the HIV transmission risks they face. Results show the importance of HIV prevention interventions from peers, and underline the need to maintain efforts to develop specific interventions targeting MSM more efficiently in the African context.

Background
While dolutegravir has been added by WHO as a preferred second-line option for the treatment of HIV infection, boosted protease inhibitor (bPI)-based regimens are still needed as alternative second-line options. Identifying optimal bPI-based second-line combinations is essential, given associated high costs and funding constraints in low- and middle-income countries. We assessed the cost-effectiveness of three alternative bPI-based second-line regimens in Burkina Faso, Cameroon and Senegal.
Methods
We used data collected over 2010–2015 in the 2LADY trial/post-trial cohort. Patients with first-line antiretroviral therapy (ART) failure were randomly assigned to tenofovir/emtricitabine + lopinavir/ritonavir (TDF/FTC LPV/r; arm A), abacavir + didanosine + lopinavir/ritonavir (arm B), or tenofovir/emtricitabine + darunavir/ritonavir (arm C). Costs (US dollars, 2016), quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios were computed for each country over 24 months of follow-up and extrapolated to 5 years using a simulated patient-level Markov model. We assessed uncertainty using cost-effectiveness acceptability curves, scenarios and prices threshold analysis.
Results
In each country, over 24 months, arm A was significantly less costly than arms B and C (incremental costs ranging from US$410–$US721 and US$468–US$546 for B and C vs A, respectively) and offered similar health benefits (incremental QALY: − 0.138 to 0.023 and − 0.179 to 0.028, respectively). Over 5 years, arm A remained the least costly, health benefits not being significantly different between arms. Compared with arms B and C, in each study country, Arm A had a ≥ 95% probability of being cost-effective for a large range of cost-effectiveness thresholds, irrespective of the scenario considered.
Conclusions
Using TDF/FTC LPV/r as a bPI-based second-line regimen provided the best economic value in the three study countries.
