RESUMO

Objectives: The study sought to determine the prevalence and risk factors associated with Hepatitis B surface antigenemia (HBsAg) positivity among pregnant women in Jos, Nigeria. Methodology: This was a cross-sectional study carried out among the pregnant population in five healthcare facilities in Jos, between November 1, 2017 and April 30, 2018. Informed consent was obtained, and data on sociodemographic and risk factors for hepatitis B virus (HBV) infection were collected. Hepatitis B viral infection was assessed using the in vitro HBsAg diagnostic rapid kit (Acon Laboratories, USA). Descriptive statistics, Chi-square test, and logistic regression were performed to identify predictors of HBV infection in the study population. All statistical analyses were carried out on STATA version 15. Results: Of the 3,238 women enrolled, 7.4% (241/3238) (95% confidence interval [CI] = 6.6% to 8.4%) were HBsAg positive. The absence of HBV vaccination (adjusted odds ratio [AOR] = 2.49; 95% CI = 1.49-4.09; P < 0.001), co-infection with HIV (AOR = 1.90; 95% CI = 1.18-3.08; P = 0.009), and higher parity (AOR = 1.37; 95% CI = 1.04-1.79; P = 0.024) were independently associated with HBV infection in pregnancy. Conclusions: The prevalence of HBV infection among pregnant women was high, especially among those without prior vaccination for HBV, those with HIV co-infection and higher parity.


RésuméObjectifs: L'étude visait à déterminer la prévalence et les facteurs de risque associés à la positivité à l'antigénémie de surface de l'hépatite B (AgHBs) chez les femmes enceintes à Jos, Nigéria. Méthodologie: Il s'agit d'une étude transversale réalisée auprès de la population enceinte dans cinq dans les établissements de santé de Jos, entre le 1er novembre 2017 et le 30 avril 2018. Un consentement éclairé a été obtenu et des données sociodémographiques et des facteurs de risque d'infection par le virus de l'hépatite B (VHB) ont été collectés. L'infection virale de l'hépatite B a été évaluée à l'aide du diagnostic in vitro de l'HBsAg kit rapide (Acon Laboratories, USA). Des statistiques descriptives, un test du chi carré et une régression logistique ont été effectués pour identifier les prédicteurs de Infection par le VHB dans la population étudiée. Toutes les analyses statistiques ont été effectuées sur STATA version 15. Résultats: Sur les 3 238 femmes inscrites, 7,4% (241/3238) (intervalle de confiance à 95% [IC] = 6,6% à 8,4%) étaient positifs pour l'AgHBs. L'absence de vaccination contre le VHB (cotes ajustées rapport [AOR] = 2,49; IC à 95% = 1,49­4,09; P <0,001), co-infection par le VIH (AOR = 1,90; IC à 95% = 1,18­3,08; P = 0,009) et plus la parité (AOR = 1,37; IC à 95% = 1,04-1,79; P = 0,024) était indépendamment associée à l'infection par le VHB pendant la grossesse. Conclusions: le la prévalence de l'infection par le VHB était élevée chez les femmes enceintes, en particulier chez celles qui n'avaient pas été vaccinées contre le VHB, celles avec le VIH co-infection et parité plus élevée.

RESUMO

During a survey of the prevalence of Candida spp. in Jos, Plateau State, Nigeria, two atypical C. albicans isolates were recovered. These two yeasts were germ tube positive, chlamydospore-negative and gave a green color on CHROMagar Candida. Molecular analysis performed by amplification of the hwp1 gene showed that these two isolates belonged to C. africana, a newly proposed Candida species closely related to C. albicans. Based on the presence or absence of an intron in DNA sequences encoding rRNA, the two C. africana, including all C. albicans isolates examined, were found to belong to genotype A and no other genotypes or species such as C. dubliniensis were found. To our knowledge, this is the first isolation of C. africana in Nigeria.
