Ethics of health research partnerships in Global South : PhD students in learning.

In view of the worldwide epidemic processes that require and result in simultaneous research in several countries and in an increasingly more structured scientific community, especially in countries of Global South, it is essential to establish partnerships between researchers, policy-makers, local supervisors, and communities in both the North and the South. The objectives of this essay are to: 1) present the context and issues linked to research in the framework of a North-South partnership; 2) describe the development of appropriate responses to improve consideration of ethical aspects; and 3) discuss the current role of young researchers in this era of multiple partnerships and share the observations and thoughts of PhD students in one research unit.

Stabilization of HIV infection rates in urban Burkina Faso, 1995-1999.

The objectives of this study were to monitor the trends of the HIV epidemic between 1995 and 1999 among pregnant women in Bobo-Dioulasso, the second largest town of Burkina Faso, and to discuss the possible effect of preventive interventions (condom availability) on sexual transmission of HIV in this context. Age-specific trends in HIV prevalence obtained from sentinel surveillance programme were analysed. Among antenatal clinic attendees, HIV prevalence was 7.5% (n=401) in 1995, 10% (n=200) in 1996, 7.6% (n=448) in 1997, 8.4% (n=642) in 1998 and 5.3% (n=716) in 1999 without demonstrated temporal trend (P=0.12). The average number of condoms available per person (aged 15-49 years) per year increased from 0.6 in 1992 to 5.7 in 1995 and 6.0 in 1999. Anonymous surveys are less subject to selection bias and suggest a stabilization of the HIV prevalence around 7.3% in Bobo-Dioulasso. Distribution of condoms could explain at least, partly, this stabilization of the HIV epidemic.

[Quality of care and sexually transmitted infections algorithm acceptability in Burkina Faso]. / Qualité des soins et acceptabilité des algorithmes de prise en charge des infections sexuellement transmissibles au Burkina Faso.

BACKGROUND: To assess sexually-transmitted infections (STIs) quality of care, syndromic approach acceptability and applicability by patients and health workers in Burkina Faso. METHOD: Three approaches were used: simulated patients method to assess quality of STIs care, patients interview and focus discussion with health workers to assess syndromic approach acceptability and applicability. RESULTS: Sixty-two anonymous visits were made in 17 Bobo-Dioulasso primary care clinics. Overall, history taking were assessed in 77.4% of visits, 47% patients were physically examined. Women (71%) were examined more frequently than men (41%) (P=0.01), 42% of patients were not examined in an isolated room. Medication was prescribed for 87.1% of the patients but only 37.5% of the treatments were applied according to national recommendations. Counselling was poor concerning critical messages regarding risk of HIV transmission, STI prevention. Patients and health workers found the syndromic approach acceptable and applicable, but the question of sexual behaviour was considered difficult to address. CONCLUSION: Quality of STIs care is poor in Burkna Faso. Staff training must emphasize interpersonal communication and motivation, with introduction of a sexually-transmitted infection syndrome package consisting of drugs and condoms in order to improve syndromic case management.

[Impaired fertility in women infected with HIV-1. Implications for sentinel serosurveillance]. / Réduction de la fertilité chez les femmes infectées par le VIH-1. Implications pour la sérosurveillance sentinelle.

BACKGROUND: Given the relationship between HIV infection and fertility, antenatal clinic-based HIV prevalence may not provide a good estimate of the community HIV prevalence. The objective of this work was to evaluate the impact of HIV infection on fertility among women attending antenatal clinics in Bobo-Dioulasso (Burkina Faso), and to discuss possible implications on HIV sentinel surveillance. METHODS: In the context of a phase II/III clinical trial of a short course of Zidovudine during pregnancy (DITRAME - ANRS 049 trial) we consecutively proposed voluntary counselling and HIV testing (VCT) to 1349 women aged at least 18 years, carrying a pregnancy of 7 months or less and living in Bobo-Dioulasso. During pre-test counselling session, a standardised questionnaire was administered to collect detailed information regarding socio-demographic characteristics and obstetrical history. Blood samples were then taken and tested for HIV after written informed consent. RESULTS: Mean age (+/- standard deviation) at first sexual intercourse was similar among HIV-infected (HIV+) (16.7+/- 2; n=83) and HIV-negative (HIV-) women (16.9+/- 2; n=1336). However, HIV+ women aged 25 years and above had, on the average fewer pregnancies (3.8+/- 1.5; n=37) than HIV- women (5.0+/- 2.3; n=567), p<0.01. Similarly, these HIV+ women had, on average, less live births (2.8+/- 1.3; n=35) than HIV- ones (3.7+/- 2.1; n=555), p=0.02. Other sexual and obstetrical characteristics such as maternal age, proportion of primigravidae, stillbirths or spontaneous abortions were comparable between HIV+ and HIV- women. CONCLUSIONS: Our data suggest that the level of fertility of HIV+ women aged 25 years and above is significantly lower than for HIV- women. Therefore, HIV+ women in this age group are likely to be under-represented among antenatal clinic attendees. These findings suggest adjusting antenatal clinic-based HIV sentinel surveillance data for age and fertility in order to derive a good estimate of the community HIV prevalence.

[Maternal HIV infection and the anthropometric characteristics of children at birth in Burkina Faso. DITRAME Study Group]. / Infection maternelle par le VIH et paramètres anthropométriques de l'enfant à la naissance au Burkina Faso.

The aim of this study was to investigate the relationship between maternal HIV status and the anthropometric characteristics of children at birth. A cross-sectional study was conducted in Bobo-Dioulasso from January 1995 to May 1996. We included all mother-child pairs seen postpartum for whom the HIV status of the mother had been determined at an antenatal visit and anthropometric measurements had been taken for the child at birth. Birth weights below 2,500 g were classed as "low", body lengths of less than 47 cm at birth were described as "small birth size" and head circumferences of less than 33 cm were classed as "small". We included 956 mothers and 956 children in the survey. Low birth-weights were recorded more frequently among children born to HIV-infected mothers than among those born to uninfected mothers (23. 37% versus 15.6%; p = 0.006). Mean birth-weight, birth size and head circumference did not differ significantly between the children of HIV-infected and uninfected mothers. In multivariate analysis, HIV infection and primiparity were independently associated with low birth-weight. Maternal HIV infection was the only factor associated with small birth size. There was no relationship between head circumference and maternal HIV status. Thus, maternal HIV infection appears to be associated with low birth-weight and small birth size.

[Campaigns for HIV testing, an effective strategy for universal access to prevention and treatment? The experience of Burkina Faso]. / Les campagnes de dépistage du VIH, une stratégie efficace pour l'accès universel à la prévention et au traitement ? L'expérience du Burkina Faso.

OBJECTIVES: Increasing the rate of people who know their HIV status is imperative, particularly in sub Saharan Africa, and this requires an assessment of strategies for increasing the utilization of testing services. This article discusses the relevance, feasibility, and effectiveness of national screening campaigns conducted between 2006 and 2010 in Burkina Faso. METHODOLOGY: An analysis of all data regarding testing uptake from 2006 to 2010 was conducted, along with interviews of key participants in the process. RESULTS: The results show that the 8 screening campaigns led to HIV testing of 487,727 people, that is, 50% of the total number of people tested and 24.6 % of HIV+ people diagnosed during this period. Campaigns succeeded in testing populations that are difficult to reach (especially young people), at a low cost. CONCLUSIONS: This strategy is relevant and useful for identifying HIV+ people. Its utility for HIV prevention campaigns requires further study. Campaigns are effective and cost-effective even in this country with a low disease prevalence. These results underline the importance of the synergy between community-based organizations and health services in the provision of counseling and testing.

[Why people delay seeking care after a positive HIV test: a qualitative study in Burkina]. / La déperdition entre les postes de dépistage et de prise en charge des personnes vivant avec le VIH-sida au Burkina Faso : une approche qualitative.

UNLABELLED: Delayed care-seeking occurs when a person who received a positive HIV serology test result does not immediately seek medical treatment for this HIV infection. It has serious consequences for patient survival. This study aims to analyze the factors leading to delayed care-seeking in this circumstance. METHODOLOGY: Applying a qualitative approach, we conducted individual interviews and focus groups in 9 community-based organizations of people living with HIV and AIDS in Burkina Faso. In total, 112 people including 70 HIV-positive patients, 30 healthcare providers, and 12 people leaving the laboratory after an HIV test, were interviewed. A thematic content analysis identified the factors that delayed care-seeking. RESULTS: Several factors explain the delay in seeking care. The weight of the negative representations of HIV and AIDS, its impact on those diagnosed with them, and fear of stigmatization (especially by family members) are major factors in delayed care. The poor quality of pre- and post-test counseling is another factor. This study also shows that financial barriers remain important in this delay. CONCLUSION: These findings suggest that earlier HIV care may be possible through efforts to reduce stigma, removal of financial barriers, and improvement of the quality of pre- and post-test counseling in mobile-device strategies and during large-scale testing campaigns.

Living with HIV: women's experience in Burkina Faso, West Africa.

Our study aimed at studying HIV-infected women's experience with sharing serostatus with their partner and their group support. A survey was carried out among 79 seropositive women involved in a therapeutic trial in Bobo-Dioulasso, following freely consented prenatal HIV testing. The study revealed that women are reluctant to inform their partners and fear being stigmatized by relatives and friends. The major concern reported was health consequences and most women wished to receive care. The non-governmental organizations supporting people living with HIV were not known by these women, but providing this information raised a high interest and many women considered joining them soon and getting themselves involved. These community-based organizations, lead by qualified and highly motivated volunteers, could facilitate a better social integration of HIV infected women in Burkina Faso.

Seroprevalence of syphilis among women attending urban antenatal clinics in Burkina Faso, 1995-8. The DITRAME Study Group. DIminunation de la TRAnsmission Mère-Enfant.

OBJECTIVES: To describe annual trends in syphilis seroprevalence and to identify risk factors of syphilis among pregnant women receiving antenatal care in Bobo-Dioulasso, Burkina Faso. METHODS: Women were recruited between January 1995 and July 1998 in three antenatal clinics where counselling and HIV testing services had been established in the context of a trial evaluating a short course of zidovudine to reduce mother to child transmission of HIV (ANRS 049 trial). Sociodemographic variables were collected during HIV pretest counselling sessions. Syphilis diagnosis was considered when serum was positive with both rapid plasma reagin and Treponema pallidum haemagglutination assay (TPHA) tests. RESULTS: Overall, 10,980 pregnant women were screened. Syphilis seroprevalence was 0.24% (95% confidence interval (CI): 0.15-0.35) without changes over time. HIV prevalence was 8.8% (CI: 8.3-9.3). In a multivariable analysis, having casual sex partners (odds ratio (OR) = 4.48; CI: 1.62-12.38), being HIV seropositive (OR = 2.62; CI: 1.02-6.74), and being illiterate (OR = 3.78; CI: 1.24-11.48) were independent risk factors for syphilis infection. CONCLUSIONS: This study suggests low syphilis seroprevalence in this city of Burkina Faso. Sexually transmitted disease programmes should be reinforced to offer free access to syphilis screening and treatment in order to eliminate this disease, in coordination with HIV prevention and care.

Sexual and reproductive life of women informed of their HIV seropositivity: a prospective cohort study in Burkina Faso.

BACKGROUND: In the context of the DITRAME-ANRS 049 research program that evaluated interventions aimed at reducing mother-to-child transmission of HIV (MTCT) in Bobo-Dioulasso (Burkina Faso), Voluntary HIV counseling and testing (VCT) services were established for pregnant women. HIV-infected women were advised to disclose their HIV serostatus to their male partners who were also offered VCT, to use condoms to reduce sexual transmission, and to choose an effective contraception method to avoid unwanted pregnancies. This study aimed at assessing how HIV test results were shared with male sexual partners, the level of use of modern contraceptive methods, and the pregnancy incidence among these women informed of the risks surrounding sexual and reproductive health during HIV infection. METHODS: From 1995 to 1999, a quarterly prospective follow-up of a cohort of HIV-positive women. RESULTS: Overall, 306 HIV-positive women were monitored over an average period of 13.5 months following childbirth, accounting for a total of 389 person-years. The mean age at enrollment in the cohort was 25.1 (standard deviation, 5.2 years). In all, 18% of women informed their partners, 8% used condoms at each instance of sexual intercourse to avoid HIV transmission, and 39% started using hormonal contraception. A total of 48 pregnancies occurred after HIV infection was diagnosed, an incidence of 12.3 pregnancies per 100 person-years. Pregnancy incidence was 4 per 100 person-years in the first year of monitoring and this rose significantly to 18 per 100 person-years in the third year. The only predictor of the occurrence of a pregnancy after HIV diagnosis was the poor outcome of the previous pregnancy (stillbirth, infant death). Severe immunodeficiency and change in marital status were the only factors that prevented the occurrence of a pregnancy after HIV diagnosis. CONCLUSION: Our study shows a poor rate of HIV test sharing and a poor use of contraceptive methods despite regular advice and counseling. Pregnancy incidence remained comparable with the pregnancy rate in the general population. To improve this situation, approaches for involving husbands or partners in VCT and prevention of MTCT interventions should be developed, evaluated, and implemented.

6-month efficacy, tolerance, and acceptability of a short regimen of oral zidovudine to reduce vertical transmission of HIV in breastfed children in Côte d'Ivoire and Burkina Faso: a double-blind placebo-controlled multicentre trial. DITRAME Study Group. DIminution de la Transmission Mère-Enfant.

BACKGROUND: Zidovudine reduces the rate of vertical transmission of HIV in non-breastfed populations. We assessed the acceptability, tolerance, and 6-month efficacy of a short regimen of oral zidovudine in African populations practising breastfeeding. METHODS: A randomised double-blind placebo-controlled trial was carried out in public clinics of Abidjan, Côte d'Ivoire, and Bobo-Dioulasso, Burkina Faso. Eligible participants were women aged 18 years or older, who had confirmed HIV-1 infection and pregnancy of 36-38 weeks duration, and who gave written informed consent. Exclusion criteria were severe anaemia, neutropenia, abnormal liver function, and sickle-cell disease. Women were randomly assigned zidovudine (n=214; 300 mg twice daily until labour, 600 mg at beginning of labour, and 300 mg twice daily for 7 days post partum) or matching placebo (n=217). The primary outcome was the diagnosis of HIV-1 infection in the infant on the basis of sequential DNA PCR tests at days 1-8, 45, 90, and 180. We compared the probability of infection at a given age in the two groups. Analyses were by intention to treat. FINDINGS: Women were enrolled between September, 1995, and February, 1998, when enrolment to the placebo group was stopped. Analysis was based on 421 women and 400 lifeborn infants. Baseline demographic, clinical, and laboratory characteristics were similar in the two groups. The Kaplan-Meier probability of HIV infection in the infant at 6 months was 18.0% in the zidovudine group (n=192) and 27.5% in the placebo group (n=197; relative efficacy 0.38 [95% CI 0.05-0.60]; p=0.027). Adjustment for centre, period of recruitment, mode of delivery, maternal CD4-cell count, duration of labour, prolonged rupture of membranes, and duration of breastfeeding did not change the treatment effect. The proportions of women taking more than 80% of the planned maximum dose were 75% before delivery, 81% during labour, and 83% post partum, without statistical difference between the groups. No major adverse biological or clinical event was reported in excess among women and children of the zidovudine group. INTERPRETATION: A short course of oral zidovudine given during the peripartum period is well accepted and well tolerated, and provides a 38% reduction in early vertical transmission of HIV-1 infection despite breastfeeding.
