HIV-1 DNA levels in peripheral blood mononuclear cells and cannabis use are associated with intermittent HIV shedding in semen of men who have sex with men on successful antiretroviral regimens.

BACKGROUND: Few data exist on the efficacy of combined antiretroviral therapy (cART) in semen of human immunodeficiency virus type 1 (HIV-1) infected men who have sex with men (MSM) with sustained control of HIV replication in blood. METHODS: HIV-1 infected MSM on successful cART for >6 months were enrolled. HIV-RNA was quantified in seminal plasma (spVL) and in blood plasma (bpVL) from 2 paired samples collected 4 weeks apart. Relationship between spVL and bpVL (measured by an ultrasensitive assay, LOQ 10 copies/mL), total peripheral blood mononuclear cells (PBMC)-associated HIV-DNA, sexually transmitted infections (STIs), and self-reported socio-behavioral characteristics was assessed using GEE logistic regression. RESULTS: In total, 157 patients were included. Median time with bpVL <50 copies/mL was 3.3 years. spVL was detectable in 23/304 samples (prevalence 7.6%). Median spVL was 145 cp/mL (100-1475). spVL was detectable on the first, on the second, and on both samples in 5, 14, and 2 men, respectively. In sum, 33 individuals (21%) had STIs (asymptomatic in 24/33). Residual bpVL was undetectable by ultrasensitive assay in 225/300 samples (75%). After multivariable adjustments, PBMC-associated HIV-DNA (OR 2.6[1.2; 6.0], for HIV-DNA > 2.5 log10 cp/10(6) PBMC, P = .02), and cannabis use during sexual intercourse (OR 2.8[1.2; 6.7], P = .02) were the only factors associated significantly with spVL. CONCLUSION: We show that HIV-RNA can be detected intermittently in semen of HIV-1 infected MSM despite successful cART. The size of blood HIV-1 reservoir predicted spVL detection. Our results indicated also that the possible effect of cannabis should be taken into account when developing prevention interventions targeted toward HIV-infected MSM on successful cART.

Empowering HIV testing as a prevention tool: targeting interventions for high-risk men who have sex with men.

In France, HIV testing can be easily performed in free and anonymous voluntary counselling testing (VCT) centres. The recent national study among French men who have sex with men (MSM) showed that 73% of those already tested for HIV had been tested in the previous two years. Nothing is known about the risk behaviours of MSM attending VCT centres. This study aimed to characterize sexual risk behaviours of MSM tested for HIV in such centres and identify factors associated with inconsistent condom use (ICU). A cross-sectional study was conducted from March to December 2009 in four VCT centres where a self-administered questionnaire was proposed to all MSM about to have a HIV test. ICU was defined as reporting non-systematic condom use during anal intercourse with casual male partners. Among the 287 MSM who fully completed their questionnaire, 44% reported ICU in the previous six months. Among those who had been already tested, 63% had had their test in the previous two years. Factors independently associated with ICU included: never avoiding one-night stands, not having been recently HIV tested, experiencing difficulty in using condoms when with a HIV negative partner or when under the influence of drugs or alcohol and finally, reporting to have had a large number of casual male partners in the previous six months. The rate of recently tested MSM was high in our study. Nevertheless, this rate was lower than that found in the last national study. Furthermore those not recently tested were significantly more likely to report high risk behaviours. We therefore recommend that further efforts be made to adapt the offer of both HIV testing and counselling to meet the specific needs of hard-to-reach MSM. Accordingly, an additional community-based offer of HIV testing to reach most-at-risk MSM is forthcoming in France.

The burden of HIV experience and care among MSM having an HIV-positive seroconcordant steady partner: a possible research hypothesis. Results from the French VESPA ANRS EN-12 study.

OBJECTIVES: Prevention fatigue, relapse into unsafe sex practices and sexual behaviour changes have been reported in the community of men who have sex with men (MSM) since the introduction of highly active antiretroviral therapy. Engaging in a relationship with a seroconcordant partner is perceived by some HIV-positive MSM as an alternative prevention strategy to consistent condom use. This study addresses whether underlying clinical factors exist characterising HIV-positive MSM in seroconcordant stable partnerships, enrolled in the French national cross-sectional survey VESPA ANRS EN-12. METHODS: The study group comprised 322 HIV-positive MSM in stable relationships for more than 12 months, with a serodiscordant (n = 251) or seroconcordant (n = 71) steady partner. Clinical and psychosocial factors were analysed for HIV-positive MSM with a seroconcordant steady partner. RESULTS: Multiple adjustment by logistic regression showed that individuals with a seroconcordant steady partner were more likely to have a history of an AIDS-defining event (OR 95% CI 2.0 (1.1 to 3.7), p = 0.02) or be diagnosed as HIV positive before 1990 (OR 95% CI 2.2 (1.3 to 3.9), p = 0.004). Conversely, HIV-positive MSM experiencing virological success (ie, high treatment adherence and an undetectable viral load) were more likely to have a serodiscordant steady partner (OR 95% CI 0.5 (0.3 to 0.9), p = 0.02). CONCLUSIONS: Longitudinal studies are required to understand to what extent HIV history might influence partnership choices among HIV-positive MSM. Positive prevention programmes and reinforcement of treatment adherence strategies are needed for this population and their steady sexual partners.

Limited access to HIV prevention in French prisons (ANRS PRI2DE): implications for public health and drug policy.

BACKGROUND: Overpopulation, poor hygiene and disease prevention conditions in prisons are major structural determinants of increased infectious risk within prison settings but evidence-based national and WHO guidelines provide clear indications on how to reduce this risk. We sought to estimate the level of infectious risk by measuring how French prisons adhere to national and WHO guidelines. METHODS: A nationwide survey targeting the heads of medical (all French prisons) and psychiatric (26 French prisons) units was conducted using a postal questionnaire and a phone interview mainly focusing on access to prevention interventions, i.e. bleach, opioid substitution treatment (OST), HBV vaccination and post-exposure prophylaxis (PEP) for French prisoners. Two scores were built reflecting adherence to national and WHO international guidelines, ranging from 0 (no adherence) to 10 (maximum adherence) and 0 to 9 respectively. RESULTS: A majority (N=113 (66%)) of the 171 prisons answered the questionnaires, representing 74% coverage (46,786 prisoners) of the French prison population: 108 were medical units and 12 were psychiatric units. Inmate access to prevention was poor. The median[IQR] score measuring adherence to national guidelines was quite low (4.5[2.5; 5.5]) but adherence to WHO guidelines was even lower 2.5[1.5; 3.5]; PEP was absent despite reported risky practices. Unsuitable OST delivery practices were frequently observed. CONCLUSIONS: A wide gap exists between HIV prevention policies and their application in prisons. Similar assessments in other countries may be needed to guide a global policy reform in prison settings. Adequate funding together with innovative interventions able to remove structural and ideological barriers to HIV prevention are now needed to motivate those in charge of prison health, to improve their working environment and to relieve French prisoners from their currently debilitating conditions.

Desire for a child among HIV-infected women receiving antiretroviral therapy in Cameroon: results from the national survey EVAL (ANRS 12-116).

The majority of HIV-infected people in sub-Saharan Africa are women, many of reproductive age. Cameroon is severely hit by the AIDS epidemic and has developed a large national program for improving access to antiretroviral treatment (ART). The reproductive intentions of women living with HIV/AIDS (WLHA) who obtain access to ART in this country remain poorly documented. Our study aimed at exploring factors associated with the desire to have a child among 1433 ART-treated fertile WLHA aged <50. Analyses were based on data collected during the national cross-sectional survey EVAL (ANRS 12-116), which was conducted between September 2006 and March 2007 in 27 HIV care centers in Cameroon. Logistic regression was used to explore factors associated with women's desire to have a child, defined as reporting the wish to have a/another child. A total of 791 women (55%) reported the desire to have a child. After adjusting for age, matrimonial status, number of biological children, and sexual activity, the main factors independently associated with this desire in a multivariate analysis were having a good physical health-related quality of life (1.02 [1.01-1.03] for a one-point increment on the 12-item Short-Form Health Survey scale) and a CD4 count at ART initiation <200 cells/mm(3) (1.7 [1.2-2.4]). As a conclusion, the desire to have a child is frequent among ART-treated WLHA in Cameroon. HIV care and family planning programs should be integrated more thoroughly in order to support WLHA's reproductive choices.

Buprenorphine in primary care: risk factors for treatment injection and implications for clinical management.

AIMS: Though the introduction of office-based buprenorphine has greatly contributed to stem the HIV epidemic since 1995, concerns have been raised about the intravenous use of buprenorphine even in patients on substitution treatment. The aim of this study was to identify which factors are predictive of buprenorphine injection in patients receiving office-based buprenorphine. DESIGN AND SETTING: Subazur is a survey consisting of two longitudinal assessments of 111 stabilized patients receiving office-based buprenorphine in southeastern France. MEASUREMENTS: Patients were interviewed by phone at enrolment and 6 months later about social characteristics, addictive behaviors, treatment experiences, overdoses and suicide ideation or attempt. A logistic regression based on generalized estimating equations (GEE) was used to identify factors associated with buprenorphine injection at any interview. FINDINGS: Among the 111 patients (32% women, mean age 38 years), 36 reported buprenorphine injection after having started treatment initiation in 40 interviews. After adjustment for time since first injection, individuals perceiving their prescribed dosage as inadequate (OR=2.6 95%CI[1.2-5.7]) and those reporting a history of suicide ideation or attempt (OR=2.7 95%CI[1.1-7.0]) had approximately a three-fold higher risk of injecting buprenorphine. CONCLUSIONS: Providing adequate care for both drug dependence and psychiatric comorbidities in primary care is a major issue. Like heroin use during methadone treatment, buprenorphine injection should be regarded more as a response to inadequate care than simply as a "misuse". A re-assessment of the treatment efficacy through a possible dosage increase or a switch to methadone could potentially reduce diversion and assure sustained adherence to OST.

Investigating Recent Testing among MSM: Results from Community-Based HIV Rapid Testing Attendees in France.

Background. We aimed to identify factors associated with recent HIV testing in MSM who attended two experimental community-based and nonmedicalized voluntary counselling and testing programmes (CB-VCT) targeting MSM in France. Methods. This analysis was based on data collected in 2009-2011 through a self-administered pretesting questionnaire. An index measuring the level of participants' sexual orientation disclosure was built: the higher the index, the greater the disclosure. Factors associated with recent HIV testing (last test ≤ 1 year) were identified using a multivariate logistic regression model adjusted for the CB-VCT programme of enrolment. Results. 716 MSM provided data on testing history. Overall, 49% were recently tested for HIV and 51% were not. Recently tested MSM had a higher homosexuality disclosure index (adjusted OR [95% confidence interval]: aOR = 1.2 [1.1-1.4]), reported more inconsistent condom use during anal sex with men (aOR = 1.6 [1.2-2.1]), and were less likely to have sex under the influence of club drugs (aOR = 0.6 [0.4-1.0]). Conclusion. New testing strategies should focus on those who live their homosexuality relatively secretly and those who use club drugs before sex. Governments should develop policies which encourage improved social acceptance of homosexuality as concealment of sexual orientation represents a major barrier to testing.

Impact of HIV comprehensive care and treatment on serostatus disclosure among Cameroonian patients in rural district hospitals.

This work aimed to analyze the rate of disclosure to relatives and friends over time and to identify factors affecting disclosure among seropositive adults initiating antiretroviral therapy (ART) in rural district hospitals in the context of decentralized, integrated HIV care and task-shifting to nurses in Cameroon. Stratall was a 24-month, randomized, open-label trial comparing the effectiveness of clinical monitoring alone with laboratory plus clinical monitoring on treatment outcomes. It enrolled 459 HIV-infected ART-naive adults in 9 rural district hospitals in Cameroon. Participants in both groups were sometimes visited by nurses instead of physicians. Patients with complete data both at enrolment (M0) and at least at one follow-up visit were included in the present analysis. A mixed Poisson regression was used to estimate predictors of the evolution of disclosure index over 24 months (M24).The study population included 385 patients, accounting for 1733 face-to-face interviews at follow-up visits from M0 to M24. The median [IQR] number of categories of relatives and friends to whom patients had disclosed was 2 [1]-[3] and 3 [2]-[5] at M0 and M24 (p-trend<0.001), respectively. After multiple adjustments, factors associated with disclosure to a higher number of categories of relatives and friends were as follows: having revealed one's status to one's main partner, time on ART, HIV diagnosis during hospitalization, knowledge on ART and positive ratio of follow-up nurse-led to physician-led visits measuring task-shifting. ART delivered in the context of decentralized, integrated HIV care including task-shifting was associated with increased HIV serological status disclosure.

Time patterns of adherence and long-term virological response to non-nucleoside reverse transcriptase inhibitor regimens in the Stratall ANRS 12110/ESTHER trial in Cameroon.

BACKGROUND: Although treatment adherence is a major challenge in sub-Saharan Africa, it is still unknown which longitudinal patterns of adherence are the most detrimental to long-term virological response to non-nucleoside reverse transcriptase inhibitor (NNRTI) regimens. This analysis aimed to study the influence of different time patterns of adherence on virological failure after 24 months of treatment in Cameroon. METHODS: Antiretroviral therapy (ART) adherence data were collected using face-to-face questionnaires administered at months 1, 3, 6, 12, 18 and 24. Virological failure was defined as viral load >40 copies/ml at month 18 and/or 24. Two combined indicators of early adherence (months 1, 3 and 6) and adherence during the maintenance phase (months 12, 18 and 24) were designed to classify patients as always adherent during the early or maintenance phase, non-adherent at least once and having interrupted ART for >2 days at least once at any visit during either of these two phases. RESULTS: Virological failure occurred in 107 (42%) of the 254 patients included in the analysis. In the early and maintenance phases, 84% and 76%, respectively, were always adherent, 5% and 5% were non-adherent and 11% and 20% experienced ≥ 1 treatment interruption. Early non-adherence was independently associated with virological failure (adjusted OR 7.2 [95% CI 1.5, 34.6]), while only treatment interruptions had a significant impact on virological failure during the maintenance phase (adjusted OR 2.1 [95% CI 1.1, 4.4]). CONCLUSIONS: ART NNRTI-regimens used in sub-Saharan Africa seem to 'forgive' deviations from good adherence during the maintenance phase. Optimizing adherence in the early months of treatment remains crucial, especially in a setting of poor health care infrastructure and resources.

Expanding access to non-medicalized community-based rapid testing to men who have sex with men: an urgent HIV prevention intervention (the ANRS-DRAG study).

BACKGROUND: Little is known about the public health benefits of community-based, non-medicalized rapid HIV testing offers (CBOffer) specifically targeting men who have sex with men (MSM), compared with the standard medicalized HIV testing offer (SMOffer) in France. This study aimed to verify whether such a CBOffer, implemented in voluntary counselling and testing centres, could improve access to less recently HIV-tested MSM who present a risk behaviour profile similar to or higher than MSM tested with the SMOffer. METHOD: This multisite study enrolled MSM attending voluntary counselling and testing centres' during opening hours in the SMOffer. CBOffer enrolees voluntarily came to the centres outside of opening hours, following a communication campaign in gay venues. A self-administered questionnaire was used to investigate HIV testing history and sexual behaviours including inconsistent condom use and risk reduction behaviours (in particular, a score of "intentional avoidance" for various at-risk situations was calculated). A mixed logistic regression identified factors associated with access to the CBOffer. RESULTS: Among the 330 participants, 64% attended the CBOffer. Percentages of inconsistent condom use in both offers were similar (51% CBOffer, 50% SMOffer). In multivariate analyses, those attending the CBOffer had only one or no test in the previous two years, had a lower intentional avoidance score, and met more casual partners in saunas and backrooms than SMOffer enrolees. CONCLUSION: This specific rapid CBOffer attracted MSM less recently HIV-tested, who presented similar inconsistent condom use rates to SMOffer enrolees but who exposed themselves more to HIV-associated risks. Increasing entry points for HIV testing using community and non-medicalized tests is a priority to reach MSM who are still excluded.

Does HIV services decentralization protect against the risk of catastrophic health expenditures?: some lessons from Cameroon.

OBJECTIVE: Scaling up antiretroviral treatment (ART) through decentralization of HIV care is increasingly recommended as a strategy toward ensuring equitable access to treatment. However, there have been hitherto few attempts to empirically examine the performance of this policy, and particularly its role in protecting against the risk of catastrophic health expenditures (CHE). This article therefore seeks to assess whether HIV care decentralization has a protective effect against the risk of CHE associated with HIV infection. DATA SOURCE AND STUDY DESIGN: We use primary data from the cross-sectional EVAL-ANRS 12-116 survey, conducted in 2006-2007 among a random sample of 3,151 HIV-infected outpatients followed up in 27 hospitals in Cameroon. DATA COLLECTION AND METHODS: Data collected contain sociodemographic, economic, and clinical information on patients as well as health care supply-related characteristics. We assess the determinants of CHE among the ART-treated patients using a hierarchical logistic model (n = 2,412), designed to adequately investigate the separate effects of patients and supply-related characteristics. PRINCIPAL FINDINGS: Expenditures for HIV care exceed 17 percent of household income for 50 percent of the study population. After adjusting for individual characteristics and technological level, decentralization of HIV services emerges as the main health system factor explaining interclass variance, with a protective effect on the risk of CHE. CONCLUSION: The findings suggest that HIV care decentralization is likely to enhance equity in access to ART. Decentralization appears, however, to be a necessary but insufficient condition to fully remove the risk of CHE, unless other innovative reforms in health financing are introduced.

Individual and structural factors associated with HIV status disclosure to main partner in Cameroon: ANRS 12-116 EVAL survey, 2006-2007.

Encouraging HIV-positive people to disclose their serostatus to their main partner is considered as a key component of secondary prevention. The purpose of this study was to identify individual and structural factors associated with HIV serostatus disclosure to one's steady partner in Cameroon, a country which has implemented a large program for access to antiretroviral therapy. We used data from the cross-sectional, nationally representative survey, ANRS 12-116 EVAL (Evaluation du programme camerounais d'accès aux traitements antirétroviraux--Impact sur la prise en charge et les conditions de vie de la population infectée par le VIH), conducted between 2006 and 2007 among HIV-infected outpatients attending health care facilities. Among the 1673 HIV-positive individuals reporting a steady partner at the time of the survey (61% women), 85.4% (n = 1429) had disclosed their serostatus to them; 77% of the respondents were receiving antiretroviral therapy. Multivariate analysis based on multilevel modeling approaches showed that the following individual factors were associated with disclosure: living with one's steady partner, living with children, reporting systematic condom use or sexual abstinence with one's steady partner, being a woman who is not the head of the household, and finally having HIV-infected people among friends or relatives and not living below the poverty line. Structural factors associated with disclosure were as follows: attending national health facilities in the country's capital cities Yaoundé or Douala and having access to psychosocial or economical support interventions. These results strengthen the argument for the introduction or development of psychosocial interventions at all levels of organization in Cameroonian hospitals as an important component of public health policies for those living with HIV.

Higher risk of unsafe sex and impaired quality of life among patients not receiving antiretroviral therapy in Cameroon: results from the EVAL survey (ANRS 12-116).

OBJECTIVE: Cameroon has initiated a national programme of HIV care decentralization providing access to antiretroviral therapy (ART) for patients with CD4 cell counts less than 200 cells/microl or AIDS stage. Current clinical research suggests these criteria may be too stringent. This study aimed at evaluating the effect of not receiving ART on patients' psychosocial outcomes. DESIGN: The national cross-sectional survey EVAL (ANRS 12-116) collected psychosocial and clinical data for 3151 patients attending HIV services (September 2006 to March 2007). METHODS: Propensity score matching was used to control for demographic/clinical-immunological differences between patients receiving ART and those who did not. Generalized linear models were used to assess the impact, for different CD4 cell levels, of "not receiving" ART on health-related quality of life (HRQoL) inconsistent condom use with a sexual partner either serodiscordant or of unknown HIV status, self-reported symptoms and disclosure of HIV status to relatives or friends. RESULTS: Seventy-eight per cent of patients included in the survey were receiving ART. Non-treated patient breakdown was as follows: 8% (CD4<200 or AIDS stage), 5% (200350). In the multivariate matched-pairs analysis, impaired physical HRQoL, more frequent inconsistent condom use, more self-reported symptoms and less frequent disclosure of HIV status were all significantly associated (P < 0.0001) with not receiving ART, irrespective of the CD4 cell level. CONCLUSION: In addition to increasing clinical effectiveness, earlier initiation of ART at less severe immune-depression levels than previously recommended by World Health Organization guidelines for low-resource settings may be justified for improving subjective health and positive prevention among people living with HIV.

HIV disclosure and unsafe sex among HIV-infected women in Cameroon: results from the ANRS-EVAL study.

Encouraging seropositive people to voluntarily disclose their serostatus has been promoted as a key component of HIV prevention. Among other reasons, HIV disclosure to one's main partner is believed to be an incentive for serodiscordant couples to practice safe sex. The present article investigated this issue by conducting a cross-sectional survey of a large sample of HIV-infected women attending HIV care centers in Cameroon (N=1014). Overall, 86.3% of these women had disclosed their serostatus to their main partner. With respect to sexual activity with their main partner during the previous three months, 35.0% had practiced abstinence and 47.4% only safe sex, whereas 17.6% had engaged in unsafe sex at least once. HIV disclosure to one's main partner was related to safe sexual practices in multivariate analysis. Some of the factors associated with disclosure and safe sex were illustrative of the positive roles of improved access to care and women's empowerment. On the contrary, beliefs overestimating the effectiveness of antiretroviral therapies were quite widespread among respondents and predictive of both concealment of HIV status and unsafe sex.

Delayed first consultation after diagnosis of HIV infection in Cameroon.

OBJECTIVES: To study the impact of both decentralization of HIV care and individual factors on delayed first consultation (> or =6 months) after HIV diagnosis in Cameroon, in the context of the national antiretroviral treatment scale-up program. DESIGN: The national cross-sectional multicenter survey EVAL (ANRS 12-116) was conducted from September 2006 to March 2007 in 27 HIV centers in Cameroon. METHODS: : Logistic regression was used to characterize patients with delayed first consultation among 3151 HIV-infected adults. RESULTS: Fifteen percent of patients reported a delay of at least 6 months before their first consultation after HIV diagnosis. In the multivariate analysis adjusted for the frequency of visits to the HIV center, independent correlates of reporting a delay of at least 6 months before consulting included the characteristics of the HIV centers (created before 2005 and located in small or medium-size hospitals) and the following individual patient characteristics: sex and matrimonial status (women living in a couple), the circumstances of the HIV diagnosis (test not performed in the hospital providing HIV care, test performed during a voluntary screening campaign) and patient's negative perception of antiretroviral treatment toxicity. CONCLUSION: Delays before first consultation for HIV care in Cameroon have been reduced, thanks to the full implementation of the national program of decentralization. Results underline the importance of coordinating diagnosis with treatment activities and the need to develop counseling actions, focusing on the balance between antiretroviral treatment effectiveness and its potential side effects. Counseling should also be part of patients' follow-up after diagnosis during voluntary screening campaigns.
