Les femmes africaines face à l'épidémie de sida

En Afrique, les femmes sont plus nombreuses que les hommes à être infectées par le virus du sida. Plus vulnérables biologiquement, elles n’ont pas toujours la capacité de négocier qui leur permettrait d’insister sur l’utilisation de préservatifs ou sur la fidélité de leur partenaire. Prévention et dépistage, encore rares, leur sont cependant plus accessibles qu’aux hommes grâce aux consultations prénatales. Mais, si elles apprennent qu’elles sont infectées, leur fragilité socio-économique, la peur de l’opprobre et la pression de procréation qu’elles subissent, conduisent trois femmes sur quatre à taire leur séropositivité. Paradoxalement, elles bénéficient pourtant plus souvent que les hommes des traitements

The implications of policy changes on the uptake of a PMTCT programme in rural Malawi: first three years of experience

Objective: To study how the demand for antenatal care (ANC), HIV testing and hospital delivery was influenced by policy changes among pregnant women in rural Malawi. Design: Retrospective analysis of monthly reports. Setting: Malamulo SDA hospital in Thyolo district, Makwasa, Malawi. Methods: Three hospital-based registers were analysed from 2005 to 2007. These were general ANC, delivery and Prevention of Mother to Child Transmission (PMTCT) registers. Observations were documented regarding the introduction of specific policies and when changes were effected. Descriptive analytical methods were used. Results: The ANC programme reached 4,528 pregnant mothers during the study period. HIV testing among the ANC attendees increased from 52.6 to 98.8% after the introduction of routine (opt-out) HIV testing and 15.6% of them tested positive. After the introduction of free maternity services, ANC attendance increased by 42% and the ratio of hospital deliveries to ANC attendees increased from 0.50:1 to 0.66:1. Of the HIV-tested ANC attendees, 52.6% who tested positive delivered in the hospital and got nevirapine at the time of delivery. Conclusions: Increasing maternity service availability and uptake can increase the coverage of PMTCT programmes. Barriers such as economic constraints that prevent women in poor communities from accessing services can be removed by making maternity services free. However, it is likely, particularly in resource-poor settings, that significant increases in PMTCT coverage among those at risk can only be achieved by substantially increasing uptake of general ANC and delivery services.We thank the Swedish Institute, Sweden for the financial support without which the study would have been a non-starter. We are also grateful for the support given by the unit of Epidemiology and Public Health Sciences, Umea University. Furthermore, we thank the management and staff of Malamulo SDA Hospital, P/Bag 2, Makwasa, Malawi for their support throughout the entire period of carrying out the study.

Couple-oriented prenatal HIV counseling for HIV primary prevention: an acceptability study

<p>Abstract</p> <p>Background</p> <p>A large proportion of the 2.5 million new adult HIV infections that occurred worldwide in 2007 were in stable couples. Feasible and acceptable strategies to improve HIV prevention in a conjugal context are scarce. In the preparatory phase of the ANRS 12127 Prenahtest multi-site HIV prevention trial, we assessed the acceptability of couple-oriented post-test HIV counseling (COC) and men's involvement within prenatal care services, among pregnant women, male partners and health care workers in Cameroon, Dominican Republic, Georgia and India.</p> <p>Methods</p> <p>Quantitative and qualitative research methods were used: direct observations of health services; in-depth interviews with women, men and health care workers; monitoring of the COC intervention and exit interviews with COC participants.</p> <p>Results</p> <p>In-depth interviews conducted with 92 key informants across the four sites indicated that men rarely participated in antenatal care (ANC) services, mainly because these are traditionally and programmatically a woman's domain. However men's involvement was reported to be acceptable and needed in order to improve ANC and HIV prevention services. COC was considered by the respondents to be a feasible and acceptable strategy to actively encourage men to participate in prenatal HIV counseling and testing and overall in reproductive health services.</p> <p>Conclusions</p> <p>One of the keys to men's involvement within prenatal HIV counseling and testing is the better understanding of couple relationships, attitudes and communication patterns between men and women, in terms of HIV and sexual and reproductive health; this conjugal context should be taken into account in the provision of quality prenatal HIV counseling, which aims at integrated PMTCT and primary prevention of HIV.</p

Predictors of HIV Serostatus Disclosure to Partners among HIV-Positive Pregnant women in Morogoro, Tanzania.

Prevention of mother to child transmission of HIV (PMTCT) has been scaled, to more than 90% of health facilities in Tanzania. Disclosure of HIV results to partners and their participation is encouraged in the program. This study aimed to determine the prevalence, patterns and predictors of HIV sero-status disclosure to partners among HIV positive pregnant women in Morogoro municipality, Tanzania. A cross sectional study was conducted in March to May 2010 among HIV-positive pregnant women who were attending for routine antenatal care in primary health care facilities of the municipality and had been tested for HIV at least one month prior to the study. Questionnaires were used to collect information on possible predictors of HIV disclosure to partners. A total of 250 HIV-positive pregnant women were enrolled. Forty one percent (102) had disclosed their HIV sero-status to their partners. HIV-disclosure to partners was more likely among pregnant women who were < 25 years old [Adjusted odds ratio (AOR) = 2.2; 95% CI: 1.2--4.1], who knew their HIV status before the current pregnancy [AOR = 3.7; 95% CI: 1.7--8.3], and discussed with their partner before testing [AOR = 6.9; 95% CI: 2.4--20.1]. Dependency on the partner for food/rent/school fees, led to lower odds of disclosure to partners [AOR = 0.4; 95% CI: 0.1--0.7]. Nine out of ten women reported to have been counseled on importance of disclosure and partner participation. Six in ten HIV positive pregnant women in this setting had not disclosed their results of the HIV test to their partners. Empowering pregnant women to have an individualized HIV-disclosure plan, strengthening of the HIV provider initiated counseling and testing and addressing economic development, may be some of the strategies in improving HIV disclosure and partner involvement in this setting

Promising outcomes of a national programme for the prevention of mother-to-child HIV transmission in Addis Ababa: a retrospective study

<p>Abstract</p> <p>Background</p> <p>Prevention of Mother-to-Child HIV Transmission (PMTCT) is still the most effective intervention in combating new HIV infections. In 2008, revised national PMTCT guidelines that incorporated new policies on HIV counselling and testing, antiretroviral prophylaxis regimen and infant HIV diagnosis came into effect in Ethiopia. In the present study we have examined trends in PMTCT service utilization and assessed the rate of MTCT in relation to policy changes in the national PMTCT programme.</p> <p>Methods</p> <p>Reports from February 2004 to August 2009 were reviewed in 10 sub-cities in Addis Ababa, Ethiopia. The data was collected from May to October 2009.</p> <p>Results</p> <p>The proportion of women who received HIV counselling and testing among new antenatal care attendees increased from 50.7% (95% CI 50.2-51.2) in 2007 to 84.5% (95% CI 84.1-84.9) in 2009 following the shift to routine opt-out testing. Nevertheless, in 2009 only 53.7% of the positive women and 40.7% of their infants received antiretroviral prophylaxis. The HIV prevalence among antenatal attendees decreased significantly from 10.5% in 2004 to 4.6% in 2009 in parallel to the increased number of women being tested. The HIV positive women were over 18 times (RR 18.5, p < 0.0001) more likely to be referred for treatment, care and support in 2009 than in 2004. The proportion of partners tested for HIV decreased by 14% in 2009 compared to 2004, although the absolute number was increasing year by year. Only 10.6% (95% CI 9.9-11.2) of the HIV positive women completed their follow up to infant HIV testing. The cumulative probability of HIV infection among babies on single dose nevirapine regimen who were tested at >=18 months was 15.0% (95% CI 9.8-22.1) in 2007, whereas it was 8.2% (95% CI 5.55-11.97) among babies on Zidovudine regimen who were tested at >=45 days in 2009.</p> <p>Conclusion</p> <p>The paper demonstrates trends in PMTCT service utilization in relation to changing policy. There is marked improvement in HIV counselling and testing service utilization, especially after the policy shift to routine opt-out testing. However, despite policy changes, the ARV prophylaxis uptake, the loss to follow up and the partner testing have remained unchanged across the years. This should be a matter of immediate concern and a topic for further research.</p

High Incidence of Unplanned Pregnancy after Antiretroviral Therapy Initiation: Findings from a Prospective Cohort Study in South Africa

Increased fertility rates in HIV-infected women receiving antiretroviral therapy (ART) have been attributed to improved immunological function; it is unknown to what extent the rise in pregnancy rates is due to unintended pregnancies.Non-pregnant women ages 18-35 from four public-sector ART clinics in Johannesburg, South Africa, were enrolled into a prospective cohort and followed from August 2009-March 2011. Fertility intentions, contraception and pregnancy status were measured longitudinally at participants' routine ART clinic visits.Of the 850 women enrolled, 822 (97%) had at least one follow-up visit and contributed 745.2 person-years (PY) at-risk for incident pregnancy. Overall, 170 pregnancies were detected in 161 women (incidence rate [IR]: 21.6/100 PY [95% confidence interval (CI): 18.5-25.2]). Of the 170 pregnancies, 105 (62%) were unplanned. Unmet need for contraception was 50% higher in women initiating ART in the past year as compared to women on ART>1 year (prevalence ratio 1.5 [95% CI: 1.1-2.0]); by two years post-ART initiation, nearly one quarter of women had at least one unplanned pregnancy. Cumulative incidence of pregnancy was equally high among recent ART initiators and ART experienced participants: 23.9% [95% CI: 16.4-34.1], 15.9% [12.0-20.8], and 21.0% [16.8-26.1] for women on ART 0-1 yr, >1 yr-2 yrs, and >2 yrs respectively (log-rank, p = 0.54). Eight hormonal contraceptive failures were detected [IR: 4.4 [95% CI: 2.2-8.9], 7/8 among women using injectable methods. Overall 47% (80/170) of pregnancies were not carried to term.Rates of unintended pregnancies among women on ART are high, including women recently initiating ART with lower CD4 counts and higher viral loads. A substantial burden of pregnancy loss was observed. Integration of contraceptive services and counselling into ART care is necessary to reduce maternal and child health risks related to mistimed and unwanted pregnancies. Further research into injectable contraceptive failures on ART is warranted
