Natural vegetation and native plant species contribute significantly to the daily needs of local people especially in developing countries. This exerts a high pressure on local species and jeopardizes the conservation of the most vulnerable plants. In Burkina Faso, conservation measures, such as the creation of protected forests, have been taken to safeguard the remaining indigenous vegetation. However, little is known about the effectiveness of these protected areas in conserving biodiversity. This study assessed and compared the population structures and regeneration potential of three vulnerable woody species—Diospyros mespiliformis Hochst., Prosopis africana (Guill. & Perr.) Taub. and Sterculia setigera Del.—in protected and unprotected areas in the Sudanian zone of Burkina Faso. The population structure and regeneration pattern of each species were compared between the North and South Sudanian sectors of Burkina Faso. The populations of all three species were unstable in both protected and unprotected areas. D. mespiliformis and P. africana displayed relatively good regeneration while P. africana lacked regeneration in unprotected areas. Regeneration was poor for S. setigera, regardless of protection status. The results suggest that the populations of the targeted species are unstable, regardless of the protection status of the area considered. This is probably due to the high anthropogenic pressure facing natural resources and raises serious concerns about the effectiveness of the protected areas in conserving biodiversity. Urgent measures are needed to ensure effective and efficient management and conservation of biodiversity in the protected areas of Burkina Faso.

Introduction In most developing countries, Cytomegalovirus (CMV), Epstein Barr virus (EBV) and Herpes virus 6 (HHV-6) are not diagnosed in blood donors. The aim of this study is to determine the prevalence of these viruses in blood donors from the city of Ouagadougou, Burkina Faso. Methods The study included 198 blood donors of the Regional Blood Transfusion Centre of Ouagadougou. Multiplex real time PCR was used to diagnose the three viruses. Statistical analysis was performed with the software EpiInfo version 6 and SPSS version 17. P values ≤ 0.05 were considered significant. Results Of 198 samples tested, 18 (9.1%) were positive to at least one of the three viruses. In fact, 10 (5.1%) were positive for EBV, 10 (5.1%) positive for CMV and 12 (6.1%) positive for HHV-6. Viral infections were higher in women than in men, EBV (8,6% versus 4.3%), CMV (8.6% versus 3.7%) and HHV-6 (11.4% versus 4.9%). EBV / CMV / HHV-6 co-infection was found in 3.5% (7/198) of blood donors. Conclusion The prevalence recorded in this study is low compared to those found in previous studies from the sub-region among blood donors. The molecular diagnostic test used in our study could explain the differences with previous studies.

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.

BackgroundIt is now well-known that some antimalarials such as primaquine may induce severe hemolytic anemia in people with G-6-PD deficiency. Antimalarial drug prescriptions must, therefore take into account the patient’s G-6-PD status in malaria endemic areas such as Burkina Faso, where the prevalence of this genetic abnormality is relatively high. Although great clinical heterogeneity is observed depending on the molecular nature of the deficiency and the residual enzyme activity in the red blood cell, there is very poor data on the prevalence of G-6-PD deficiency and the distribution of involved genetic variants in Burkina Faso. In this systematic review, we present a synthesis of the various studies carried out on the G-6-PD deficiency in Burkina Faso in order to determine its prevalence, probable distribution of the genetic variants involved and their clinical implications for a national systematic screening policy among the groups most vulnerable to malaria.MethodsA systematic review was carried out to analyze available published data on the prevalence, phenotypes and mutations responsible for G-6-PD deficiency in Burkina Faso. The key words used were “G-6-PD deficiency AND Burkina Faso” or “Déficit en G-6-PD AND Burkina Faso” in French. To identify the relevant articles, two independent reviewers reviewed the titles, abstracts and the full text of the selected papers.ResultsAn average prevalence of 16.6% (183/1100; CI 95%: 0.145–0.190) and 6.5% (69/1066; CI 95%: 0.051–0.081) of G-6-PD deficiency was found respectively in men and women in this systematic review. Although the predominance (99.8% of G-6-PD deficient cases) of 202A/376G G-6-PD A- variant, the Santamaria and Betica Selma variants were identified in Burkina Faso. Independently of the method used, the enzymatic deficiency was significantly higher in males (2.5–20.5%) compared to females (3.3–12.3%).ConclusionThis systematic review suggests that despite the ubiquity of the 202A/376G G-6-PD A- variant in Burkina Faso, it will be necessary to consider the Santamaria and Betica Selma variants although their frequencies remain to be specified. A systematic screening of the G-6-PD deficiency is also needed to prevent the occurrence of iatrogenic hemolytic accidents.RésuméContexteIl est. actuellement bien connu que certains antipaludiques comme la primaquine, peuvent induire des crises d’anémie hémolytique graves chez les personnes présentant un déficit en G-6-PD. Les prescriptions de médicaments antipaludiques doivent donc tenir compte du statut G-6-PD du patient dans les zones d’endémie du paludisme comme le Burkina Faso où la prévalence de cette anomalie génétique est. relativement élevée. En dépit d’une grande hétérogénéité clinique observée selon la nature moléculaire du déficit et l’activité résiduelle de l’enzyme dans le globule rouge, il existe très peu de données sur la prévalence du déficit en G-6-PD et la distribution des variants génétiques en cause au Burkina Faso. Dans cette revue de la littérature nous présenterons la synthèse des différents travaux réalisés sur le déficit en G-6-PD au Burkina Faso afin de déterminer sa prévalence, la distribution probable des variants génétiques en cause et leurs implications cliniques en vue d’une politique nationale de dépistage systématique au sein des groupes les plus vulnérables au paludisme.MéthodesUne revue systématique a été réalisée pour analyser les données publiées disponibles sur la prévalence, les phénotypes et les mutations du déficit en G-6-PD au Burkina Faso Les mots clés utilisés étaient « G6PD deficiency AND Burkina Faso » en anglais ou « Déficit en G6PD AND Burkina Faso en français ». Pour identifier les articles pertinents, deux examinateurs indépendants ont examiné les titres, les résumés et le texte intégral des articles retenus.RésultatsUne prévalence moyenne de 16,6% (183/1100; IC 95%: 0,145–0,190) et 6,5% (69/1066; IC 95%: 0,051–0,081) du déficit en G-6-PD a été observée respectivement chez les hommes et les femmes dans cette revue systématique. Malgré la prédominance (99,8% des cas de déficients en G-6-PD) du variant G-6-PD A- 202A/376G, les variants Santamaria et Betica Selma ont été identifiées au Burkina Faso.Indépendamment de la méthode utilisée, la prévalence du déficit enzymatique était significativement plus élevée chez les hommes (2,5–20,5%) comparativement aux femmes (3,3–12,3%).ConclusionCette revue systématique suggère qu’en dépit de l’ubiquité du variant G-6-PD A- 202A/376G au Burkina Faso, il est. nécessaire de prendre en compte les variants Santamaria et Betica Selma, bien que leurs fréquences restent à préciser. Un dépistage systématique de la déficience en G-6-PD est. également nécessaire pour prévenir la survenue d’accidents hémolytiques iatrogènes notamment chez les populations les plus vulnérables au paludisme.

Introduction Les herpès virus EBV, CMV et HHV-6 sont des virus qui évoluent sous le modèle pandémique et sont responsables d’infections congénitales pouvant provoquer des séquelles graves chez les nouveau-nés. L’objectif de cette étude était de déterminer les prévalences de CMV, EBV et HHV-6 chez les femmes enceintes VIH(+) et VIH(-) à Ouagadougou. Méthodes Dans cette étude 200 échantillons de plasma sanguin de femmes enceintes dont 100 femmes VIH(+) et 100 femmes VIH(-) ont été diagnostiqués par PCR multiplex en temps réel pour les trois infections (EBV, CMV et HHV-6). Résultats Sur l’ensemble des 200 échantillons analysés, 18 (9,0%) étaient positifs à au moins un des trois virus, 12 (6,0%) étaient positifs au EBV, 13 (6,5%) au CMV et 12 (6,0%) positifs au HHV-6. Parmi les 18 cas d’infections, nous avons trouvé 10 cas (55,6%) de coïnfections dont 90,0% (9/10) d’infection multiple EBV/CMV/HHV6 et 10,0% de coinfection EBV/HHV6. Le taux d’infection HHVs était plus élevé chez les femmes VIH(-) que celles VIH(+) (12,0% versus 6,0%). Parmi les VIH(+), la PCR a révélé 7,1% (soit 6/85) d’infection HHVs chez celles qui n’étaient pas sous ARV contre 0% chez celles sous ARV. Conclusion Les herpès virus sont fréquents chez les femmes enceintes au Burkina Faso et pourraient constituer une menace chez ces dernières à cause des complications et des risques d’infection pour le nouveau-né.
