ABSTRACT

Objective: To evaluate the implementation of a screening strategy for the partners and children of pregnant women with hepatitis B virus (HBV) attending antenatal care. Methods: We identified pregnant women positive for HBV surface antigen (HBsAg) at antenatal consultation in Ouagadougou, Burkina Faso. At post-test counselling, women were advised to disclose their HBV status to partners and to encourage their partner and children to be screened for HBsAg. We used multivariable logistic regression to explore factors associated with uptake of screening and HBsAg positivity among family members. Findings: Of 1000 HBsAg-positive women, 436/1000 partners and 215/1281 children were screened. HBsAg was detected in 55 (12.6%) partners and 24 (11.2%) children. After adjusting for confounders, uptake of screening was higher in partners who were married, who attended the woman's first post-test consultation and to whom the woman had disclosed her HBV status. In children, HBsAg positivity was associated with being born before the introduction of infant hepatitis B vaccination in Burkina Faso (not significant in the multivariable analysis), having a mother positive for HBV e-antigen (adjusted OR: 8.57; 95% CI: 2.49-29.48) or having a mother with HBV DNA level ≥ 200 000 IU/mL (OR: 6.83; 95% CI: 1.61-29.00). Conclusion: In low-income countries, the antenatal consultation provides a cost-effective opportunity to identify HBV-infected household contacts and link them to care. Children born before the introduction of infant hepatitis B vaccination and whose mother has higher viral load or infectivity should be a priority for testing and linkage to care.

ABSTRACT

Seasonal malaria chemoprevention (SMC) is effective to prevent malaria in children 3 to 59 months in the Sahel region. Mother's seasonal malaria chemoprevention related knowledge and attitudes and the coverage of the strategy among targeted children were assessed. A cross-sectional survey was conducted in 1828 children aged 3 to 59 months from November 7 to 18, 2018 in eight health regions of Burkina Faso where SMC was implemented with Malaria Consortium supported fund. Data were collected using structured questionnaire and direct inspection of SMC card. MAGPI software was used for data collection and STATA 12.0 was used for the analysis. A total of 1828 children 3 to 59 months were enrolled and 951 mothers interviewed on different aspects of SMC. Overall, the SMC coverage was high for single cycle or for cumulative coverage basis. Single cycle coverage increased over rounds, from mother and tutor's interview (from 87.09% (1592/1828) to 91.19% (1667/1828); p=0.001). Over 91.18% (869/951) knew that SMC objective was to prevent malaria. Overall SMC was well tolerated and most 95.2% (296/320) of mothers and tutors surveyed owned treated bed nets. Despite combining high coverage and treated bed-net use, at least 16.19% remained rapid diagnosis test positives during the survey. SMS coverage was high in the current survey and most mothers knew the relevance of SMC administration with high bed-net coverage.

ABSTRACT

La mortalité à 3 mois des infarctus cérébraux demeure encore élevée en Afrique Sub Saharienne. L'objectif de notre étude était d'évaluer la mortalité intra hospitalière, à un mois et à 3 mois des patients hospitalisés pour infarctus cérébral au Burkina Faso. Il s'agissait d'une étude de cohorte prospective de patients consécutivement hospitalisés pour infarctus cérébral, de mars 2015 à février 2016, puis suivis en consultation externe durant au moins 3 mois après l'AVC au Centre Hospitalier Universitaire de Tingandogo, à Ouagadougou, au Burkina Faso. Les caractéristiques sociodémographiques, cliniques et paracliniques des patients à l'admission, les complications et la mortalité cumulée respectivement à la sortie d'hospitalisation, à un mois et à 3 mois, ont été analysées. En tout, 151 patients ont été enregistrés, avec une prédominance masculine (59,6 %) et une moyenne d'âge de 63,4 ans. Lors de l'admission, le National Institute of Health Stroke Score (NIHSS) moyen était de 14. L'oedème cérébral (39,7 %) et l'effet de masse (35,1 %) était les complications neuroradiologiques précoces les plus fréquentes. La durée moyenne d'hospitalisation était de 13,4 jours. Les taux de mortalité, intra hospitalière, à un mois et 3 mois étaient respectivement de 17,9 %, 19 % et 25,9 %. La mortalité des infarctus cérébraux reste élevée en Afrique Sub Saharienne. L'utilisation de la fibrinolyse, la mise en place des unités neurovasculaires et un accès des patients à la rééducation fonctionnelle, contribueront à l'amélioration de la survie des patients après infarctus cérébraux

ABSTRACT

OBJECTIVE: We have assessed HIV-1 disease progression among HIV-1-positive mothers in relation to duration of any or exclusive breast feeding in the context of ANRS 12174 trial. METHODS: The analysis was completed on 203, 212, 272 and 529 HIV-1-positive and lactating mothers with CD4 count >350 cells/µL from Burkina Faso, South Africa, Uganda and Zambia, respectively. The trial compared lamivudine and lopinavir/ritonavir as a peri-exposure prophylaxis during a 50-week follow-up time. A multiple logistic regression model was run with the mothers' weight, CD4 count and HIV-1 viral load as separate dependent variables, then combined into a dependent composite endpoint called HIV-1 disease progression where HIV-1 viral load was replaced by the HIV-1 clinical stage. Exclusive or predominant breast feeding (EPBF) and any breastfeeding duration were the key explanatory variables. RESULTS: In the adjusted model, the associations between EPBF duration and weight change, CD4 cell count and the HIV-1 viral load were consistently insignificant. The CD4 cell count was associated with a significantly higher mothers' body mass index (BMI; a mean increase of 4.9 (95% CI 2.1 to 7.7) CD4 cells/µL per each additional kilogram per square metre of BMI) and haemoglobin concentration (19.4 (95% CI 11.4 to 27.4) CD4 cells/µL per each additional gram per decilitre of haemoglobin concentration). There was no significant association between EPBF duration and HIV-1 disease progression. A higher education level was a factor associated with a slower HIV-1 disease progression. CONCLUSION: Breast feeding was not a risk factor for a faster progression of HIV-1 disease in mothers of this cohort with a baseline CD4 cell count >350 cells/µL. TRIAL REGISTRATION NUMBER: NCT0064026; Post-results.

ABSTRACT

INTRODUCTION: Breastfeeding is recommended for infants born to HIV-infected women in low-income settings. Both breastfeeding and HIV-infection are energy demanding. Our objective was to explore how exclusive and predominant breastfeeding changes body mass index (BMI) among breastfeeding HIV1-positive women participating in the ANRS12174 trial (clinical trial no NCT0064026). METHODS: HIV-positive women (n = 1 267) with CD4 count >350, intending to breastfeed HIV-negative infants were enrolled from Burkina Faso, South Africa, Uganda and Zambia and counselled on breastfeeding. N = 1 216 were included in the analysis. The trial compared Lamivudine and Lopinavir/Ritonavir as a peri-exposure prophylaxis. We ran a linear mixed-effect model with BMI as the dependent variable and exclusive or predominant breastfeeding duration as the key explanatory variable. RESULTS: Any breastfeeding or exclusive/predominant) breastfeeding was initiated by 99.6% and 98.6% of the mothers respectively in the first week after birth. The median (interquartile range: IQR) duration of the group that did any breastfeeding or the group that did exclusive /predominant breastfeeding were 9.5 (7.5; 10.6) and 5.8 (5.6; 5.9)) months, respectively. The median (IQR) age, BMI, CD4 count, and HIV viral load at baseline (day 7) were 27 (23.3; 31) years, 23.7 (21.3; 27.0) kg/m2, 530 (432.5; 668.5) cells/µl and 0.1 (0.8; 13.7)1000 copies/mL, respectively. No major change in mean BMI was seen in this cohort over a 50-week period during lactation. The mean change between 26 and 50 weeks after birth was 0.7 kg/m2. Baseline mean BMI (measured on day 7 postpartum) and CD4 count were positively associated with maternal BMI change, with a mean increase of 1.0 kg/m2 (0.9; 1.0) per each additional baseline-BMI kilogram and 0.3 kg/m2 (0.2; 0.5) for each additional CD4 cell/µl, respectively. CONCLUSION: Breastfeeding was not negatively correlated with the BMI of HIV-1 infected Sub-Saharan African mothers. However, a higher baseline BMI and a CD4 count >500 cells/µl were associated with maternal BMI during the exclusive/ predominant breastfeeding period. Considering the benefits of breast milk for the infants and the recurrent results from different studies that breastfeeding is not harmful to the HIV-1-infected mothers, this study also supports the WHO 2016 guidelines on infant feeding that mothers living with HIV should breastfeed where formula is not safe for at least 12 months and up to 24 months, given that the right treatment or prophylaxis for the infection is administered. These findings and conclusions cannot be extrapolated to women who are immune-compromised or have AIDS.

ABSTRACT

BACKGROUND: Strategies to prevent postnatal mother-to-child transmission of HIV-1 in Africa, including infant prophylaxis, have never been assessed past 6 months of breastfeeding, despite breastfeeding being recommended up to 12 months after birth. We aimed to compare the efficacy and safety of infant prophylaxis with the two drug regimens (lamivudine or lopinavir-ritonavir) to prevent postnatal HIV-1 transmission up to 50 weeks of breastfeeding. METHODS: We did a randomised controlled trial in four sites in Burkina Faso, South Africa, Uganda, and Zambia in children born to HIV-1-infected mothers not eligible for antiretroviral therapy (CD4 count >350 cells per µL). An independent researcher electronically generated a randomisation schedule; we then used sequentially numbered envelopes to randomly assign (1:1) HIV-1-uninfected breastfed infants aged 7 days to either lopinavir-ritonavir or lamivudine (paediatric liquid formulations, twice a day) up to 1 week after complete cessation of breastfeeding or at the final visit at week 50. We stratified the randomisation by country and used permuted blocks of four and six. We used a study label on drug bottles to mask participants, study physicians, and assessors to the treatment allocation. The primary outcome was infant HIV-1 infection between age 7 days and 50 weeks, diagnosed every 3 months with HIV-1 DNA PCR, in the modified intention-to-treat population (all who attended at least one follow-up visit). This trial is registered with ClinicalTrials.gov, number NCT00640263. FINDINGS: Between Nov 16, 2009, and May 7, 2012, we enrolled and randomised 1273 infants and analysed 1236; 615 assigned to lopinavir-ritonavir or 621 assigned to lamivudine. 17 HIV-1 infections were diagnosed in the study period (eight in the lopinavir-ritonavir group and nine in the lamivudine group), resulting in cumulative HIV-1 infection of 1.4% (95% CI 0.4-2.5) and 1.5% (0.7-2.5), respectively. Infection rates did not differ between the two drug regimens (hazard ratio [HR] of lopinavir-ritonavir versus lamivudine of 0.90, 95% CI 0.35-2.34; p=0.83). Clinical and biological severe adverse events did not differ between groups; 251 (51%) infants had a grade 3-4 event in the lopinavir-ritonavir group compared with 246 (50%) in the lamivudine group. INTERPRETATION: Infant HIV-1 prophylaxis with lopinavir-ritonavir was not superior to lamivudine and both drugs led to very low rates of HIV-1 postnatal transmission for up to 50 weeks of breastfeeding. Infant pre-exposure prophylaxis should be extended until the end of HIV-1 exposure and mothers should be informed about the persistent risk of transmission throughout breastfeeding.

ABSTRACT

BACKGROUND: HIV-1 transmission rates have been reduced over the last decade, an estimated 2 million new infections per year arise, including 220,000 paediatric cases. The main post-natal HIV exposure is through breastfeeding, where both its duration and modality (exclusive or not) are associated with postnatal transmission. The ANRS 12174 trial compared HIV-1 postnatal transmission of 2 prophylaxis drugs for infants during lactation (lamivudine and lopinavir-ritonavir). Our objective has been to examine the feeding practices and the determinants of exclusive/ predominant (EPBF) or any breastfeeding among the participants of this trial in Burkina Faso, South Africa, Uganda and Zambia. METHODS: Mothers infected with HIV-1 and their uninfected offspring were followed from day 7 after birth for 50 weeks, keeping monthly records of their feeding patterns. Feeding was classified into 3 categories: 1) exclusive breastfeeding during the first six months, only breast-milk being given to infant for 6 months, 2) predominant breastfeeding, breast-milk with liquid-based items being given, and 3) mixed feeding, other non-breast milk or solid food being given in addition to breast milk with or without liquid-based items. The categories were merged into 2 groups: EPBF applying to infants aged <6 months and mixed feeding applying to infants of any age. The feeding patterns have been given as Kaplan-Meier curves. A flexible parametric multiple regression model was used to identify the determinants of the mothers' feeding behaviour. RESULTS: A total of 1,225 mother-infant pairs provided feeding data from Burkina Faso (N = 204), South Africa (N = 213), Uganda (N = 274) and Zambia (N = 534) between November 2009 and March 2013. The mean maternal age was 27.4 years and the mean BMI was 24.5. 57.7 and 93.9% of mothers initiated breastfeeding within the first hour and first day, respectively. Overall, the median durations of any form of breastfeeding and EPBF were 40.6, and 20.9 weeks, respectively. Babies randomized to the lopinavir/ritonavir group in South Africa tended to do less EPBF than those in the lamivudine group. Overall the group of mothers aged between 25 and 30 years, those married, employed or multiparous tended to stop early EPBF. Mothers living in Uganda or Zambia, those aged between 25 -30 years, better educated (at least secondary school level), employed or having undergone C-section stopped any breastfeeding early. CONCLUSIONS: There is a need to improve breastfeeding and complementary feeding practices of children, particularly those exposed to HIV and anti-retrovirals, taking into account context and socio-demographic factors. TRIAL REGISTRATION: Clinical trial registration: NCT00640263.

ABSTRACT

BACKGROUND: In the context of universal access to prevention, treatment, care and support, each country has to ensure that 80% of women and children in need have access to PMTCT interventions. OBJECTIVE: To assess the PMTCT program achievement in Ouagadougou, the capital city of Burkina Faso. METHODS: Between August and October 2008, a cross sectional study was carried out in the five health districts of the Centre Health Region. We reviewed weekly statistics from all health care centres (HCC) to compute the coverage of PMTCT program. In 38 HCC with functional PMTCT program, we extracted data of interest from HCC registers and made direct observations of PMTCT services. RESULTS: The PMTCT program was implemented in 49% of HCC (target for the national program: 70%). Fifteen to 31% of these centers were often in shortage for PMTCT consumables. Patients' privacy was not observed in 67% of Voluntary Counselling & HIV Testing wards. Care providers were not qualified enough to deliver PMTCT services. Vitamin A supplementation was not implemented. None of the facilities offered the whole package of PMTCT program interventions. HCC providing HIV testing in labour or in postnatal ward were consistently lacking. Only 86% of antenatal care new attendants benefited from pre-test counselling; 2.4% of pretested women were HIV-positive and 39% of positive mothers received antiretroviral prophylaxis. CONCLUSION: Coverage and quality of PMTCT programme in the Centre Health Region in Burkina Faso are still limited. Particular support is needed for training, supervision and infrastructures upgrading.
