RESUMO
ABSTRACTTransition is the next major hurdle in the field of HIV-infected youth, especially in sub-Saharan Africa. At St Camille Hospital in Ouagadougou, fully informed and compliant patients over 13-years-old were eligible for referral to the adult HIV/AIDS service, after completion of an individualized preparatory process. Transition consisted in at least two consecutive "joined-service" appointments in the respective facilities. We retrospectively compared immunological, clinical, and therapeutical data one year before transition, at transition and one year after transition. Between 2008 and 2019 73 patients (34 females, 39 males) were transitioned. All had been previously in pediatric care for at least 1 year and 66 were on HAART. Matched paired analysis of CD4 counts revealed a modest drop in CD4 cells over time (p < 0.05). Clinical data also showed strong fluctuation between WHO clinical stages over the three time points, with a clear trend towards increased severity especially post transfer. This large retrospective 12-year single-center experience from a Sahel country showed a 95.8% retention rate at one year. It demonstrates how a comprehensive plan, carefully implemented, can provide excellent retention, even in a low-resource setting. However, mild immunological decline was associated with a worrisome clinical deterioration, underlining the importance of assessing the latter after transition.

BACKGROUND: Burkina Faso is a high endemicity country for HBV infection. However, there are few data on vaccine coverage against HBV. The aim of this study was to contribute to the improvement of HBV vaccine coverage in Ouagadougou through HBV screening. METHODS: Awareness campaigns and voluntary hepatitis B screening were organized in the twelve districts of Ouagadougou by the "SOS Hepatitis Burkina" association. A rapid HBsAg detection test (Abon Biopharma Guangzhou, Co., Ltd. Chine) was performed on 2216 individuals, who voluntarily answered a series of questions. Vaccination against hepatitis B was proposed to HBV negative participants. RESULTS: In a sample of 2216 participants, aged 1 to 78 years (mean age 29.7 ± 14.7 years); a prevalence of 10.4% (230/2216) of HBsAg was obtained. This prevalence was high in the age groups 31 to 40 years (14.5%) and 41 to 50 years (15.0%). The prevalence of HBV was higher in the sixth district (14.3%) of Ouagadougou. At the end of the screening, 1202/1986 HBV negative participants were vaccinated, resulting in a vaccination rate of 60.5%. Vaccination coverage ranged from 44.5 to 73.7% all twelve districts. CONCLUSIONS: This study still reports a high prevalence of HBV infection among young people with a peak in the sixth district of Ouagadougou. The study achieved high vaccination coverage in all age groups and districts of Ouagadougou. TRIAL REGISTRATION: The present study has been approved by the Ethics Committee for Health Research of Burkina Faso. CERS201501006 Registered 14 January 2015.

BACKGROUND: Aim of our study is to investigate the clinical and immunological outcomes according to first-line HAART adherence in a large cohort of HIV-infected patients in Burkina Faso. METHODS: A retrospective study was conducted between 2001 and 2009 among patients from two urban medical centers [St. Camille Medical Center (CMSC) and "Pietro Annigoni" Biomolecular Research Center (CERBA)] and 1 in the rural District of Nanoro (St. Camille District Hospital). Socio-demographical and clinical data were analyzed. Adherence was evaluated through a questionnaire investigating 5 key points related to drugs, consultations and blood exams, by assigning 0 to 2 points each up to 10 points overall. Data were collected at baseline and regularly thereafter. Adherence score was considered as a continuous variable and classified in optimal (8-10 points) and sub-optimal (0-7 points). Immunological outcome was evaluated as modification in CD4+ T-cell count over time, while predictors of death were explored by a univariate and multivariate Cox model considering adherence score as a time-varying covariate. RESULTS: A total of 625 patients were included: 455 (72.8%) were females, the median age was 33.3 (IQR 10.2) years, 204 (32.6.%) were illiterates, the median CD4+ T-cell count was 149 (IQR 114) cells/µl at baseline. At the end of the observation period we recorded 60/625 deaths and 40 lost to follow-up. The analysis of immunological outcomes showed a significant variation in CD4+ T-cell count between M12 and M24 only for patients with optimal adherence (Δ=78.2, p<0.001), with a significant Δ between the two adherence groups at M24 (8-10 vs 0-7, Δ=53.8, p=0.004). Survival multivariate analysis revealed that covariates significantly related to death included being followed at CERBA (urban area) or Nanoro (rural area), and receiving a regimen not including fixed dose combinations, (p=0.024, p=0.001 and p<0.001 respectively); conversely, an increasing adherence score as well as an optimal adherence score were significantly related to survival (p<0.001). CONCLUSIONS: Adherence to HAART remains pivotal to build up a good therapeutic outcome. Our results confirm that, according to our adherence system evaluation, less adherent patients have a higher risk of death and of inadequate CD4+ count recovery.

Although the numbers of SARS-CoV-2 infections and related deaths are relatively low in sub-Saharan Africa, the pandemic might lead to a high indirect death toll there. We determined the impact of the COVID-19 pandemic on the management of malnourished children in urban and rural areas. We analyzed data from two Centers for Rehabilitation, Education & Nutrition (CRENs), one in the capital and one in a rural center, both run by the Camillian Fathers. We compared data from the year before the pandemic (2019) with the first 2 years during the pandemic (2020/2021). In the urban CREN, there was a sharp reduction in new patients enrolled, from 340 in the pre-pandemic year to 189 during the first pandemic year and 202 in the second year. The follow-up was significantly shorter during the first pandemic year, with a rebound in the second year (pre: 57 days versus 42 and 63 days for the first and second years, respectively). In the rural CREN, the situation was different: The numbers of patients did not show any significant variation between the pre-pandemic year (191) and the first and second pandemic years (223 and 179, respectively). Different perceptions of the pandemic in urban (high, more testing, more COVID) and rural (low, less information and testing) areas may partly explain this difference. The discrepancy between the decreasing numbers of malnourished children in specialized care during the pandemic-especially in the urban area-is contrary to the lockdown-induced increase in food insecurity and warrants attention to avoid an increase in the silent epidemic of malnourished children in Africa.

Sub-Saharan Africa records each year about thirty-two million pregnant women living in areas of high transmission of Plasmodium falciparum causing malaria. The aim of this study was to carve out the prevalence of asymptomatic malaria among pregnant women and to emphasize its influence on haematological markers. The prevalence of Plasmodium falciparum asymptomatic infection among pregnant women was 30% and 24% with rapid detection test (RDT) and microscopy, respectively. The prevalence of P. falciparum asymptomatic malaria was reduced among pregnant women using sulfadoxine-pyrimethamine's intermittent preventive treatment and 61% of them were anaemic. Anaemia was significantly more common in women infected with P. falciparum compared with the uninfected pregnant women. Most of the women had normal levels of homocysteine and low levels of folate, respectively. Therefore, the systematic diagnosis of malaria should be introduced to pregnant women as a part of the antenatal care.

OBJECTIVE: To determine hepatitis C virus (HCV) prevalence and the rate of HCV/human immunodeficiency virus (HIV) co-infection in pregnant women attending Saint Camille medical centre (SCMC) in Ouagadougou. METHODS: A total of 607 pregnant women, 16-45 years old, with <32 weeks amenorrhoea were screened for HCV and HIV using rapid tests. The majority of the women included in the study were previously known as HIV infected, as the centre is a reference centre for the programme of prevention against mother-to-child HIV transmission in the country. HCV RNA was extracted and quantified using the cDNA polymerase chain reaction with the nested primers at the 5' untranslated region. Transaminases were measured from plasma samples using spectrophotometric method. RESULTS: Of women, 62.27% were infected with HIV. The prevalence of HCV was 2.14% in the screened pregnant women: 1.75% in HIV-negative women and 2.38% in HIV-positive ones. This prevalence is not significantly different between HIV-positive and HIV-negative pregnant women (P = 0.81). HCV RNA was found in all women with anti-HCV. A significant transaminase increase was noted in women infected with HCV (P = 0.01 and P < 0.01 for glutamic-pyruvic transaminase and glutamic-oxaloacetic transaminase, respectively). Risk factors significantly associated with HCV positivity in pregnant women included transfusion and genital excision. In addition, the infection was linked with the educational level of the women. CONCLUSION: The issue of this study revealed that effort should be made to promote safe medical practices and fight against women genital excision that are found to be the main risk factors associated with the HCV infection.

BACKGROUND AND AIMS: Even if under-five children mortality tends to decrease considerably in developed countries, it remains a major concern in Sub-Saharan Africa. The purpose of the present study is to assess causes of healthcare discontinuation and factors associated with mortality among severe acute malnourished children under five years old in the health district of Gorom-Gorom in Burkina Faso. METHODS: A descriptive retrospective study on healthcare discontinuation and deaths of severely acute malnourished children under five years old who registered from July to December 2018, in the health district of Gorom-Gorom in Burkina Faso. RESULTS: A total of 377 records of children suffering from severe acute malnutrition were exploited. Children of age range 6-23 months were the most predominantly malnourished. Healthcare discontinuation was observed at rates around 24.4%.Deaths were recorded in 9.72% of children hospitalized in the CRNE and around 1% in children in the ambulatory care management. The severe acute malnutrition co-morbidity factors included oral candidiasis [OR = 14.8; (95%CI 1.128-194.285)], dehydration [OR = 11.46; (95%CI 1.085-121.038)] and malaria [OR = 8.32; (95%CI 1.915-36.191)]. CONCLUSION: The risk of death of severe acute malnourished children is higher when the disease is associated with complications.

Mother-to-child transmission remains the main cause of global pediatric HIV infections, especially in sub-Saharan Africa. Many interventions based on single-dose antiretroviral therapy have been implemented to reduce the mother-to-child transmission of HIV. In resource-limited settings, highly active antiretroviral therapy (HAART) has only been recommended for HIV-infected pregnant women requiring treatment for their own health. Here, we assessed the efficacy over 18 months of maternal HAART versus peripartum short-course antiretroviral therapy (SCART) regimens for the prevention of mother-to-child transmission (PMTCT) of HIV. We conducted a retrospective cohort study of patients from two medical centers in Ouagadougou, Burkina Faso. The PMTCT files and registers from 1 January 2003 to 31 December 2006 were obtained from routine data collected at these sites. The main assessment criterion was the rate of HIV-1 positivity in children born to HIV-positive mothers as measured with HIV-1 rapid tests at 18 months. A total of 586 pregnant HIV-1-infected women in PMTCT programs were selected. Among these women, 260 were undergoing HAART and 326 received single-dose nevirapine (91.3%) or single-dose zidovudine (8.7%) at delivery. HIV-1 serological tests were performed on 454 children at 18 months old. The rate of HIV-1 vertical transmission was 0% (0/195) in the HAART group and 4.6% (12/259) in the single-dose monotherapy group (P<0.01). Eight infants in the HAART cohort and 30 in the SCART cohort were breastfed; three in the SCART group were HIV-positive. A total of 62 children died, 19 in the HAART group and 43 in the single-dose monotherapy group. Our study confirms that HAART for mothers effectively reduces the risk of infant HIV infection while preserving the breastfeeding option for mothers.

BACKGROUND: Burkina-Faso's HIV/AIDS program is one of the most successful in Africa, with a declining HIV prevalence and treatment outcomes that rival those of developed countries. Prevention of mother-to-child transmission (PMTCT) guidelines in Burkina-Faso, initiated in the year 2000, were revised in 2004, 2006 and 2010. The guideline document has since undergone several stages of improvement, largely based on recommendations from WHO, with adaptations by local experts in the field. Option B+ adopted since August 2014 in Burkina-Faso has enabled maintenance of mothers on longer treatment and increasing their survival and that of their children. Through this review, we describe the achievements and challenges of HIV PMTCT programs in Burkina-Faso. AIMS OF STUDY: This study had the following objectives: 1) describing the historical perspective of PMTCT implementation in Burkina-Faso; 2) presenting the effectiveness of interventions at improving PMTCT service delivery and promoting retention of mothers and babies in care; and 3) determining the impact of male partner involvement on PMTCT in Burkina-Faso. METHODOLOGY: A literature search was conducted in PubMed and Google. Search terms included the following keywords: "HIV testing"; "prevention"; "mother"; "child"; "male partner"; "counseling"; "involvement"; "participation"; and the grouped terms "PMTCT and partners"; "VCT"; "barriers and/or factors"; "Male involvement in PMTCT"; and "Burkina-Faso". Data collection took place from May to October 2015. The search was limited to articles published between January 2002 and December 2015. UNICEF and UNAIDS web sites were also used to find relevant abstracts and documents. RESULTS: Studies have revealed that with PMTCT, HIV transmission rate moved from 10.4% in 2006 to 0% in 2015. The PMTCT program remains the best way to care for HIV-infected pregnant women and their babies. The current PMTCT policy is based on evidence that male partner involvement is associated with women's completion of PMTCT. CONCLUSION: This study shows that the reduction in mother to child transmission of HIV in Burkina-Faso over the years is mainly due to the improvement of PMTCT programs. Efforts still need to be made about the involvement of male partners.
RESUMO
Breast cancer is the top cause of cancer mortality among women in the world and the second in Africa. The aims of this study were to: i) identify women with breast nodules suspected of having breast cancer ii) sequence the BRCA1 and BRCA2 genes and iii) screen mutations. From 2015 to 2016, 112 women aged from 35 to 44 years, who had come for consultation in the gynecology/obstetrics and the oncology department of the University Hospital Yalgado Ouedraogo, voluntarily agreed to participate to this study. Whole blood was collected from those with mammary nodules. The genomic DNA was extracted using Qiagen kit. FAST KAPA was used for genomic DNA amplification and the purified PCR products were analyzed by direct sequencing using Big Dye v1.1 and ABI 3730 automated sequencer. Nucleotides substitutions were determined. We identified BRCA1 SNPs rs1799966, rs799917, rs16942, rs16941, rs2227945, and BRCA2 SNPs rs169547, rs4986860. These identified variants are found mostly in cases of benign tumors of breast or ovarian cancer with familial history of breast cancer. This study in Burkina-Faso, is the basis for improved and more specific genetic testing, and suggests that additional genes contributing to an increased risk of breast cancer should be analyzed.

OBJECTIVE: To investigate whether the severity of Plasmodium falciparum attack in endemic areas was associated with the multiplicity of infection (MOI) and/or with a particular genotype(s). METHOD: In two areas of different malaria transmission pattern in Madagascar (Sainte-Marie - mesoendemic and Tsiroanomandidy - hypoendemic) the number and the proportions of msp-2 genotypes within isolates were determined for each patient using a capillary electrophoresis genotyping method. DNA sequencing was performed to identify the msp-2 allelic family of dominant clones. RESULTS: Eighty six uncomplicated and 33 severe cases were included in Sainte-Marie and 48 uncomplicated and 69 severe cases were included in Tsiroanomandidy. We found no association between the MOI and severity of malaria as the same mean number of msp-2 genotypes was found in isolates from uncomplicated and from severe malaria cases (3.72 and 3.73, respectively, P>0.05). The study of the association of dominant clones with clinical status showed no particular genotype or allelic family associated with malaria severity. CONCLUSIONS: Severity of malaria was not associated with higher MOI in our study. Severity did not appear restricted to some particular genotypes either. On the contrary, severe malaria appeared to be caused by very common genotypes in the studied areas. More comprehensive explorations including immunity and genetic factors of the host are needed to acquire new information about this complex condition.

RESUMO
BACKGROUND: The presence of HBV DNA in the liver (with detectable or undetectable HBV DNA in the serum) of individuals tested HBsAg negative by currently available assays is defined occult B Infection (OBI). It remains a potential transmission threat and risk to HBV chronic infection. The purpose of this study was to determine the OBI prevalence among HBsAg negative subjects and to characterize associated genotypes. METHODS: Blood samples of 219 HBsAg-negative subjects tested by ELISA were collected. HBV DNA was investigated in all samples. Viral loads were determined using quantitative real-time PCR. All samples were screened for HBV markers (anti-HBc, anti-HBe, HBsAg). The Pre-S/S region of the HBV genome was sequenced. The database was analyzed using the SPSS and Epi info software. Phylogenetic analysis was performed using the BioEdit and MEGA software. RESULTS: Of the 219 samples, 20.1% were anti-HBc positive, 1.8% HBeAg and 22.8% were anti-HBe positive. Fifty-six (56) (25.6%) of the samples had a detectable HBV DNA and viral loads ranging from 4 IU/mL to 13.6 106 IU/mL. Sixteen of them (16/56) had a viral load < 200 IU/mL, resulting in an OBI prevalence of 7.3% (16/219) in our study. The remaining 40 subjects had viral loads > 200 IU/mL, resulting in a "false OBI" prevalence of 18.3% (40/219). HBV genotype E was predominant followed by the quasi-sub-genotype A3. A single "false OBI" strain had the characteristic mutation G145R. Other mutations were observed and all located in the major hydrophilic region (MHR) of the S gene. CONCLUSION: The study reported a prevalence of 7.3% of occult hepatitis B infection. It confirms the predominance of genotype E and the existence of a subgroup of quasi-sub-genotype A3 of HBV in Burkina Faso. It further provides information on the presence of "false OBI." This study has found mutations in the major hydrophilic region (MHR) of the pre-S/S gene of HBV.
RESUMO
The emergence of HIV-1 drug resistance (HIVDR) is a public health problem that affects women and children. Local data of HIVDR is critical to improving their care and treatment. So, we investigated HIVDR in mothers and infants receiving antiretroviral therapy (ART) at Saint Camille Hospital of Ouagadougou, Burkina Faso. This study included 50 mothers and 50 infants on ART. CD4 and HIV-1 viral load were determined using FACSCount and Abbott m2000rt respectively. HIVDR was determined in patients with virologic failure using ViroSeq HIV-1 Genotyping System kit on the 3130 Genetic Analyzer. The median age was 37.28 years in mothers and 1.58 year in infants. Sequencing of samples showed subtypes CRF02_AG (55.56%), CRF06_cpx (33.33%) and G (11.11%). M184V was the most frequent and was associated with highlevel resistance to 3TC, FTC, and ABC. Other mutations such as T215F/Y, D67N/E, K70R, and K219Q were associated with intermediate resistance to TDF, AZT, and 3TC. No mutation to LPV/r was detected among mothers and infants. The findings of HIVDR in some mothers and infants suggested the change of treatment for these persons.
RESUMO
The low rate of screening for hepatitis B virus (HBV) in pregnant women is a highrisk factor for its vertical transmission. The objectives of this study were: i) to screen pregnant women for HBV infection; ii) vaccinate all children from birth against HBV regardless their mother HBV status; and iii) evaluate after 7 months of birth the level of their AbHBs among babies who received HBV vaccine at birth. Serological markers of HBV (HBsAg, HBeAg, AbHBs, AbHBe, and AbHBc) were determined on venous blood samples from 237 pregnant women and their children using the Abon Biopharm Kit. One hundred and two (102) children received the three doses of the EUVAX B® vaccine respectively at birth, two months and four months of life. Seven months after delivery, venous blood samples were collected from mothers and their children. Antibodies against hepatitis B surface antigen (AbHBs) were measured in vaccinated children using the ELISA Kit AbHBs Quantitative EIA. DNA extraction was performed on samples from HBV-seropositive mothers and their children using the Ribo Virus (HBV Real-TM Qual) Kit and for Real Time PCR, the HBV Real-TM Qual Kit was used. Serological diagnosis in pregnant women revealed 22 (9.28%) hepatitis B surface antigen (HBsAg) positive samples of which 21 were positive for viral DNA by real-time PCR. Among the 22 HBsAg+ women, five (05) transmitted the virus to their children with a vertical transmission rate of 22.73%. A transmission rate of 23.81% (5/21) was found with the PCR method. Analysis of AbHBs levels revealed that 98.31% of the children had an average concentration of 218.07 ± 74.66 IU/L, which is well above the minimum threshold for protection (11 IU/L). This study has confirmed that vertical transmission of HBV is a reality in Burkina Faso and that vaccination at birth would significantly reduce this transmission.
RESUMO
BACKGROUND: The authors studied the modalities of nonadherence to highly active antiretroviral therapy (HAART) and its sociodemographic associated factors and those in relation to caregiving perception in Ouagadougou. METHODS: A cross-sectional study was performed from December 2013 to February 2014 in 2 health centers. Adults receiving HAART for at least 3 months were included. Adherence was studied according to the quantitative, qualitative, and global criteria. Factors associated with nonadherence were analyzed with chi-square and Fisher tests. A logistic regression model was applied for multivariate analysis. RESULTS: The authors studied 152 patients: mean age 40.7 ± 7.8 years and sex ratio 0.34. Frequencies were 7.2% for self-reported quantitative, 20.4% for calculated quantitative, 31.6% for qualitative, and 38.2% for global nonadherence. Married status (P = .02), patient's dissatisfaction regarding clinical monitoring (P = .01), and therapeutic education (P = .03) were associated with nonadherence. In multivariate analysis, married status remains associated (odds ratio = 7.00, 95% confidence interval = 1.89-25.8, P = .0004). CONCLUSION: Nonadherence to HAART needs to be correctly managed during HIV/AIDS monitoring.

INTRODUCTION: Herpesvirus EBV, CMV and HHV-6 are viruses that evolve based on pandemic modeling and are responsible for congenital infections causing severe sequelae in infants. This study aims to determine the prevalence of CMV, EBV and HHV-6 among HIV (+) and HIV (-) pregnant women in Ouagadougou. METHODS: In this study 200 blood plasma samples taken from pregnant women, of whom 100 with HIV(+) and 100 with HIV(-), were analyzed using multiplex real-time PCR which detected three infections (EBV, CMV and HHV-6). RESULTS: Out of the 200 samples tested, 18(9.0%) were positive for at least one of the three viruses, 12(6.0%) were positive for EBV, 13(6.5%) were positive for CMV and 12(6.0%) were positive for HHV-6. Among the 18 cases with infections, 10 cases (55.6%) had co-infections of whom 90.0% (9/10) with multiple EBV/CMV/HHV6 infection and 10.0% with EBV/HHV6 co-infection. HHVs infection rate was higher among HIV (-) pregnant women than among HIV (+) pregnant women (12.0% versus 6.0%). Among HIV (+) pregnant women, PCR showed 7.1% (6/85) of HHVs infection in patients who were not treated with ARV against 0% in those treated with ARVs. CONCLUSION: Herpes virus infections are a common condition in pregnant women in Burkina Faso. They may represent a real threat to pregnant women because of complications and risks of infection in infants.

We evaluated the performance of a malaria rapid diagnostic test (RDT; Malaria Quick Test(®); Cypress Diagnostic) compared with the standard thick-smear microscopy method using blood samples from human immunodeficiency virus (HIV)-infected individuals and individuals of unknown HIV status collected in Ouagadougou, Burkina Faso. Our results show that 42.1% of 114 HIV-infected patients were concordantly RDT- and thick smear-positive, and 55.3% were concordantly negative. Sensitivity and specificity of the RDT test were 100.0% and 95.4%, respectively, with 5.9% false-positive results and a total agreement of 97.4%; 127 patients with unknown HIV serology were analyzed; of them, 40.9% were RDT- and thick smear-positive, and 46.4% concordantly negative. Sensitivity and specificity were 100.0% and 78.6%, respectively, with 23.5% false-positive results and a total agreement of 87.4%. Malaria Quick Test(®) is rapid and effective for the diagnosis of malaria and has a high sensitivity, confirming its use in general and HIV patients in particular.

Objective. This study aimed to investigate the association between three polymorphisms of renin-angiotensin system and the essential hypertension in the population of Burkina Faso. Methodology. This was a case-control study including 202 cases and 204 matched controls subjects. The polymorphisms were identified by a classical and a real-time PCR. Results. The AGT 235M/T and AT1R 1166A/C polymorphisms were not associated with the hypertension while the genotype frequencies of the ACE I/D polymorphism between patients and controls (DD: 66.83% and 35.78%, ID: 28.22% and 50.98%, II: 4.95% and 13.24%, resp.) were significantly different (p < 10(-4)). The genotype DD of ACE gene (OR = 3.40, p < 0.0001), the increasing age (OR = 3.83, p < 0.0001), obesity (OR = 4.84, p < 0.0001), dyslipidemia (OR = 3.43, p = 0.021), and alcohol intake (OR = 2.76, p < 0.0001) were identified as the independent risk factors for hypertension by multinomial logistic regression. Conclusion. The DD genotype of the ACE gene is involved in susceptibility to hypertension. Further investigations are needed to better monitor and provide individualized care for hypertensive patients.
RESUMO
BACKGROUND: Vertical human immunodeficiency virus (HIV) transmission is a public health problem in Burkina Faso. The main objective of this study on the prevention of mother-to-child HIV-1 transmission was to determine the residual risk of HIV transmission in infants born to mothers receiving highly active antiretroviral therapy (HAART). Moreover, we detect HIV antiretroviral (ARV) drug resistance among mother-infant pairs and identify subtypes and circulating recombinant forms (CRF) in Burkina Faso. DESIGN: In this study, 3,215 samples of pregnant women were analyzed for HIV using rapid tests. Vertical transmission was estimated by polymerase chain reaction in 6-month-old infants born to women who tested HIV positive. HIV-1 resistance to ARV, subtypes, and CRFs was determined through ViroSeq kit using the ABI PRISM 3,130 sequencer. RESULTS: In this study, 12.26% (394/3,215) of the pregnant women were diagnosed HIV positive. There was 0.52% (2/388) overall vertical transmission of HIV, with rates of 1.75% (2/114) among mothers under prophylaxis and 0.00% (0/274) for those under HAART. Genetic mutations were also isolated that induce resistance to ARV such as M184V, Y115F, K103N, Y181C, V179E, and G190A. There were subtypes and CRF of HIV-1 present, the most common being: CRF06_CPX (58.8%), CRF02_AG (35.3%), and subtype G (5.9%). CONCLUSIONS: ARV drugs reduce the residual rate of HIV vertical transmission. However, the virus has developed resistance to ARV, which could limit future therapeutic options when treatment is needed. Resistance to ARV therefore requires a permanent interaction between researchers, physicians, and pharmacists, to strengthen the network of monitoring and surveillance of drug resistance in Burkina Faso.
