Abstract:
Background: Significant bacteriuria is commonly reported in pregnancy which greatly predisposes pregnant women to urinary tract infection (UTI), one of the commonest health challenges in pregnancy worldwide especially in developing countries such as Nigeria. The objectives of this study are to determine the prevalence of and factors associated with significant bacteriuria among pregnant women attending the antenatal clinic (ANC) of Adeoyo Maternity Hospital, Yemetu, Ibadan, Nigeria, as well as determine the bacterial aetiology and antimicrobial susceptibility patterns of the isolates.

Abstract:

Background: Hepatitis B virus (HBV) infection is a global public health challenge with over 360 million people infected worldwide, and is one of the leading causes of death worldwide. The hepatitis B surface antigen (HBSAg) is the most important marker for HBV screening, and HBSAg rapid screening test methods are the most widely used compared with the enzyme-linked immunosorbent assay (ELISA) and nucleic acid testing methods. The objectives of this study are to evaluate the comparative efficacy of rapid test kits and ELISA for HBV screening among pregnant women on antenatal visits and to screen for other HBV serological markers among HBsAg positive patients.

Methodology: This is a cross-sectional study of 172 pregnant women who were recruited consecutively on their first antenatal visit at the University College Hospital, Ibadan, Nigeria between November 2018 and February 2019. All participants were screened for HBsAg using both rapid immunochromatographic test (ICT) and ELISA techniques. HBsAg negative samples were further screened for anti-HBeAg/Ab, anti-HBcAg and anti-HBs by ELISA. Socio-demographic data of the participants were obtained using a semi-structured questionnaire, and data were analyzed using EPI INFO 7.2 statistical software.

Abstract:
Background: Toxoplasmosis is a common worldwide infection caused by the protozoan Toxoplasma gondii. In Cameroon, several recent studies have reported high seroprevalence of this parasitosis in various hospitals (Douala, Limbe, Njinikom and Yaoundé). The aim of this study was to determine whether this high prevalence of toxoplasmosis might occur in other regions of the country.
Methodology: Serological tests by the indirect Enzyme Linked Immunosorbent Assay (ELISA) for IgG and IgM were carried out on 200 pregnant women (36 HIV-positive and 164 HIV-negative) at the Protestant Hospital of Mbouo-Bandjoun in western Cameroon to determine the presence of Toxoplasma gondii infection and to identify the risk factors associated with seropositivity of the subjects.
Results: The overall seroprevalence of anti-Toxoplasma antibodies was 45.5%. The prevalence rate was 80.5% in the HIV-positive group (47.2% IgG, 22.2% IgM and 11.1% IgG + IgM) and 37.8% in the HIV-negative group (25.6%, 9.7% and 2.4% respectively). Using a multivariate logistic regression analysis, the secondary level of educational, presence of HIV infection, and frequency of close contacts with cats were significantly associated with the prevalence of IgG and/or IgM antibodies.
Conclusion: Compared with previous reports of human toxoplasmosis in Cameroon, the prevalence in our study showed a decrease in the disease occurrence. Further studies are needed to determine whether this decrease is localised to our study or a general phenomenon currently affecting the country.

Résumé:
Contexte: La toxoplasmose est une infection répandue dans le monde entier et causée par le protozoaire Toxoplasma gondii. Au Cameroun, plusieurs études récentes ont signalé une forte séroprévalence de la parasitose dans divers hôpitaux (Douala, Limbé, Njinikom et Yaoundé). Le but de cette étude était de déterminer si cette forte prévalence de la toxoplasmose pouvait se produire dans d’autres régions du pays.
Méthodologie: Des tests sérologiques pour quantifier les IgG et IgM par dosage indirect immuno-enzymatique indirect selon la méthode ELISA ont été effectués sur 200 femmes enceintes (36 VIH-positives et 164 VIH-négatives) à l’hôpital protestant de Mbouo-Bandjoun, dans l’ouest du Cameroun, afin de déterminer la présence d’infectiona à T. gondii et d’identifier les facteurs de risque associés à la séropositivité des sujets.
Résultats: La séroprévalence globale des anticorps anti-Toxoplasma était de 45,5 %. Le taux de prévalence était de 80,5 % dans le groupe VIH-positif (47,2 % IgG, 22,2 % IgM et 11,1 % IgG + IgM) et de 37,8 % dans le groupe VIH négatif (25,6 %, 9,7 % et 2,4 %, respectivement). L’emploi d’une analyse de régression logistique multivariée a montré que le niveau secondaire d’éducation, la présence d’une infection par le VIH et la fréquence des contacts étroits avec les chats étaient significativement associés à la prévalence des anticorps IgG et/ou IgM.
Conclusion: Par rapport aux rapports précédents sur la toxoplasmose humaine au Cameroun, la prévalence dans notre étude a montré une diminution de la fréquence de la maladie. Des études complémentaires sont nécessaires pour déterminer si cette baisse est localisée dans notre étude ou est un phénomène général qui affecte actuellement le pays.

Abstract

Toxoplasma gondii infection causes devastating defects including,  blindness, neurological impairment and mental retardation in congenitally infected children. Congenital infection occurs when a woman becomes infected during pregnancy; and the severity of the illness is related to the trimester period. This research was designed to evaluate the  seroprevalence of toxoplasmosis amongst pregnant women (n=90) using enzyme linked immunosorbent assay (ELISA) kit (Cortez Diagnostics Inc. USA). A structured questionnaire was used to collect socio-demographic data. A significant (x2 Cal 233.0/ x2 tab 124.1, p=0.01) overall prevalence of 22.2% (20/90) was obtained. Pregnant women within 25-29years had the highest prevalence of 33.3% (3/9); this was significant (x2 Cal 35.85/ x2 tab 9.21, p=0.01). An association between high levels of toxoplasma IgG and miscarriage was established in four of twenty five women who had suffered miscarriage (t cal 5.3/t tab 2.81, p=0.01). The results presented indicate that toxoplasmosis is a significant public health burden in the area of study, which requires drastic remedial measures.

L’infection de Toxoplasma gondii provoque des malformations dévastatrices, y compris, la cécité, des troubles neurologiques et un retard mental chez les enfants infectés congénitalement. L’infection congénitale se produit quand une femme est infectée au cours de la grossesse, et la gravité de la maladie est liée à la période de trimestre. Cette recherche a été conçue pour évaluer la séroprévalence de la toxoplasmose chez les femmes enceintes (n = 90) à l’aide de dosage immunoenzymatique (ELISA) (Cortez Diagnostics Inc. USA). Un questionnaire structuré a été utilisé pour
recueillir des données socio- démographiques. Une prévalence importante globale de 22,2 % (20/ 90) a été obtenu (p =0,01). Les femmes  enceintes dans les tranche d’âge25- 29 ans ont eu la plus forte prévalence de 33,3 % (3/9)qui était significative (p = 0,01). Une association entre des niveaux élevés de Toxoplasme IgG et fausse couche a été établie dans quatre des vingt-cinq femmes qui avaient subi une fausse couche (p = 0,01). Les résultats présentés indiquent que la toxoplasmose est un problème de santé publique dans cette localité, ce qui nécessite des mesures correctives drastiques.
