[Assessment of a programme of prevention of mother-to-child transmission of HIV in Abidjan, Ivory Coast (1999-20002)]. / Evaluation d'un programme de prévention de la transmission mère- enfant ou VIH à Abidjan (Côte d'Ivoire/1999-2002).

The purpose of this article is to report the results of a programme for prevention of mother-to-child transmission (PMCT) of HIV conducted from 1999 to 2002 by the PNLS in Abidjan, Ivory Coast. This programme was supported by grants from the Fonds de solidarité international (FSTI) and the Glaxo Smith Kline (GSK) Foundation. After pre- and posttest counselling, pregnant women from 4 PMI centres underwent screening for HIV. Seropositive women were offered short course AZT and the possibility of financial assistance for breast-feeding. All programme activities were carried out in close cooperation with association members. A total of 22466 tests were given and 18116 women returned for results. Among the 1829 seropositive women to whom PMCT intervention was proposed, 667 received short course AZT. The rate of transmission at 18 months was 162%. In addition 69 mothers and 28 children eligible for ARV therapy benefited from tritherapy. Limiting factors, at each phase, and efficacy of intervention were analyzed.

[Syphilis test proposed within the context of a programme to reduce mother/child HIV transmission: example of the Wassakara Health Care Center in Abidjan]. / Dépistage de la syphilis dans le cadre d'un pro- gramme de réduction de la transmission mère-enfant du VIH : exemple du centre de santé de Wassakara a Abidjan.

During the program MTCT+ set up in Abidjan by the national authorities with the assistance of the FSTI and FGSK, free screening and treatment of the syphilis infection were proposed to pregnant women. One test of agglutination on blades VDRL (Carbon Antigen Biotec the U.K.) and one TPHA test on plates for the positive VDRL (TPHA Nosticon Biomérieux F) were performed. Over the period from June 1999 to December 2001, 4 320 samples were taken. The laboratory observed 84 positive tests VDRL and 59 confirmed by TPHA, that is to say a syphilis seroprevalence (TPHA) of 1.4%. In addition 391 results were not available for various reasons (errors of numbering, haemolysed blood, absence of reagents, etc.) ie. 9.0%. Among the 59 positive women (TPHA), 30 came back for their result and 23 women were correctly treated (3 or 4 penicillin delay injections). In addition 7 partners received a complete treatment and 8 incomplete treatment. The cost of each detected and treated case rose approximately to 150 Euros, which is relatively low except in time/ staff and indirect costs for women. This study confirmed that all the activities of SMI must be integrated to have an efficient PTME programme. The biological assessment must be accessible as a whole, to minimize the additional costs and transportations. A training of all the personnel in 2002 helped to improve in an important way the results of the intervention in the center.

Impaired fertility in HIV-1-infected pregnant women: a clinic-based survey in Abidjan, Côte d'Ivoire, 1997.

OBJECTIVE: Differences in fertility among HIV-1-positive and HIV-negative women tested in prenatal clinics were suspected by routine data collection in Abidjan, Côte d'Ivoire. This study was conducted on detailed fertility patterns among women at the same antenatal care centres, in order to assess these differences. METHOD: The survey was carried out on 1201 consecutive women who agreed to be tested for HIV. Data collected included a detailed account of pregnancies, the time interval between the last two pregnancies, and the health status at the time of the survey. Blood samples were tested for HIV and syphilis with informed consent. RESULTS: Despite an earlier exposure to pregnancy risk, HIV-1-infected women aged 25 years and above, had, on the average, fewer pregnancies than uninfected women. An analysis of the interval between the last two pregnancies among multigravidae showed that, all things being equal, being HIV-1 positive decreased the risk of being pregnant by 17% (Cox regression, hazard ratio = 0.83, 95% confidence interval (CI): 0.69-0.99). This shift in the occurrence of the last pregnancy was more profound among HIV-1-positive women already at the symptomatic or AIDS stage, than among asymptomatic women. CONCLUSION: These data confirm that women infected by HIV-1 would become pregnant less often than uninfected women, for an equal exposure to the risk of pregnancy. Therefore HIV-1-positive women could be under-represented at antenatal centres. Programmes involving such settings both for epidemiological surveillance and the reduction of mother-to-child transmission should take this observation into account.

Haematological characteristics and HIV status of pregnant women in Abidjan, Côte d'Ivoire, 1995-96.

To describe the haematological profile of pregnant women and to compare these characteristics according to HIV serostatus in Abidjan, Côte d'Ivoire, a cross-sectional study was made in the context of a research intervention programme to reduce mother-to-child transmission (MTCT) of HIV (ANRS 049 trial). HIV testing was systematically proposed to pregnant women attending the mother and child health clinic of a community health centre. Blood samples were tested for HIV antibodies using Genelavia and Peptilav. The haematological parameters were measured with a Coulter counter. From May 1995 to March 1996, 1646 pregnant women accepted HIV testing and had a full blood count available. The prevalence of HIV infection was 12.0% (n = 197). The prevalence of anaemia (haemoglobin [Hb] < 11 g/dL) was 70.1%, n = 1155 (95% confidence interval 68-72%) and significantly higher in HIV+ (81.7%, n = 161) than in HIV- women (68.9%, n = 994) (P < 0.001). Severe anaemia (Hb < 7 g/dL) was present in 1.9% of the women (n = 31), 4.6% (n = 9) in HIV+ and 1.5% (n = 22) in HIV- women (P < 0.001). HIV infection, primigravidae and secundigravidae were factors independently associated with anaemia. Anaemia was highly prevalent in this population while severe anaemia was rare. HIV infection was a contributor to anaemia in pregnancy. As zidovudine, with its known haematological toxicity, has recently been introduced to prevent MTCT of HIV in developing countries, screening HIV+ women for severe anaemia is necessary.

HIV-1 infection and reproductive history: a retrospective study among pregnant women, Abidjan, Côte d'Ivoire, 1995-1996. Ditrame Project.

The aim of this paper is to determine the differences of fertility between HIV-1 infected and uninfected women in Abidjan, Côte d'Ivoire, using data available in an observational study conducted in 1995 and 1996 in 2 antenatal care centres in the district of Yopougon, Abidjan, within an intervention programme to reduce mother-to-child HIV-1 transmission (DITRAME project, ANRS 049). Fertility indicators have been constructed from retrospective data on pregnancies and births, and univariate and multivariate analyses have been performed on these indicators and stratified by age groups to compare HIV-1 positive and HIV-negative populations. The main outcome measures were the number of pregnancies, the number of miscarriages, the risk of miscarriage and the proportion of primigravida. Four thousand, three hundred and ninety-six women agreed to HIV testing: 12.1% were found to be HIV-1 infected. HIV-1 positive women had significantly fewer pregnancies than HIV-negatives in age-groups 25-29 (P = 0.05) and 30-34 (P = 0.008). The risk of having had at least one abortion or stillbirth was significantly higher for HIV-1 infected women than for HIV-negatives (OR = 1.28, 95% CI: 1.02-1.60), when controlling for social and demographic factors. This study suggests that HIV-1 infection has deleterious consequences on female fertility, with lower fertility rates and more frequent adverse pregnancy outcomes. Family planning and antenatal care services should consider antenatal HIV counselling and testing in women in areas of high HIV prevalence.

Vaginal douching: association with lower genital tract infections in African pregnant women.

BACKGROUND AND OBJECTIVES: Douching, a common practice, could further increase the risk of genital infections. GOAL OF THIS STUDY: To describe douching practices in pregnant women and to evaluate associations with lower genital tract infections. STUDY DESIGN: Cross-sectional study in Abidjan, Côte d'Ivoire. RESULTS: Among 552 women included, douching before consultation was reported by 97% and was common practice for 98%. Intravaginal drying agents were used by 10%. Genital warts were less frequent for women who usually douched (p = 0.015). U. urealyticum infection was associated with douching and with the use of intravaginal agents. Diagnosis of genital infections was independent of douching with water or soap, but chlamydial infection was associated with douching with antiseptics, used by 14% of the women (p = 0.036). HIV infection was two times more frequent in women using antiseptics (p = 0.17). CONCLUSION: The study confirms the widespread practice of douching in African pregnant women. The harmful effects of antiseptics need to be substantiated.
