Caesarean delivery of first prediagnosed COVID-19 pregnancy in Nigeria.

The COVID-19 pandemic is currently causing widespread infection and deaths around the world. Since the identification of the first case in Nigeria in February 2020, the number of confirmed cases has risen to over 9,800. Although pregnant women are not necessarily more susceptible to infection by the virus, changes to their immune system in pregnancy may be associated with more severe symptoms. Adverse maternal and perinatal outcomes have been reported among pregnant women with COVID-19 infection. However, literature is scarce on the peripartum management and pregnancy outcome of a pregnant woman with COVID-19 in sub-Saharan Africa. We report the first successful and uncomplicated caesarean delivery of a pregnant woman with COVID-19 infection in Nigeria.

Association between maternal serum homocysteine concentrations in early pregnancy and adverse pregnancy outcomes.

Background: There is still conflicting evidence on the extent to which maternal hyperhomocysteinemia is a risk factor for pregnancy complications. Aims: The study aimed to investigate the impact of elevated maternal homocysteine concentrations on adverse pregnancy outcomes among Nigerian women in Lagos. Materials and Methods: This was a prospective cohort study conducted at the Lagos University Teaching Hospital, Idi-Araba, Lagos, Nigeria. Participants were enrolled during the first trimester of pregnancy following which relevant data were obtained by the interview. Fasting blood samples were collected for the measurement of maternal homocysteine concentration using the enzyme-linked immunosorbent assay method. Pregnancy outcomes and complications were obtained by abstracting the antenatal, delivery, and newborn medical records. Preterm births, low-birth weight (LBW), and antepartum fetal death were used as confirmatory outcome variables in the final analysis. Descriptive statistics for all data were computed using SPSS version 22.0. The associations between the variables were tested and multivariate analyses were used to study the effects of the major baseline characteristics on the pregnancy outcome. P < 0.05 was considered statistically significant. Conclusions: The prevalence of hyperhomocysteinemia among mothers in Lagos was relatively low. The associations between hyperhomocysteinemia and adverse pregnancy outcomes could have implications in future for the prevention of these adverse outcomes. Results: Hyperhomocysteinemia was recorded in 41 (24.6%) patients. Women with a high homocysteine concentration and those with a normal homocysteine level did not differ significantly in terms of age (P = 0.684), level of education (P = 0.866), and parity (P = 0.647). Women with hyperhomocysteinemia had an approximately twelve-fold higher risk of preterm birth (P = 0.001) and a ten-fold higher risk of delivering a term neonate with LBW (P = 0.004), but had no risk of antepartum fetal death (P = 0.118) compared to women with a normal homocysteine concentration.

RésuméHistorique: Il existe encore des preuves contradictoires sur la mesure dans laquelle l'hyperhomocysteinemia maternel est un facteur de risque de complications de grossesse. Objectifs: L'étude visait à étudier l'impact des concentrations élevées d'homocystéine maternelle sur les résultats défavorables de la grossesse chez les Femmes nigérianes à Lagos. Matériel et Méthodes: Il s'agissait d'une étude de cohorte prospective menée à l'Hôpital universitaire d'enseignement de Lagos, Idi-Araba, Lagos, Nigeria. Les participants ont été inscrits au cours du premier trimestre de la grossesse, après quoi les données pertinentes ont été obtenues par l'entrevue. Des échantillons de sang à jeun ont été prélevés pour la mesure de la concentration maternelle d'homocystéine utilisant le méthode d'essais immunosorbent. Les résultats et les complications de grossesse ont été obtenus en reprochant le prénatal, l'accouchement, et le médical nouveau-né medical Dossiers. Les naissances prématurées, le faible poids à la naissance (LBW) et la mort fœtale antepartum ont été utilisés comme variables de résultats confirmatoires dans l'analyse finale. Les statistiques descriptives pour toutes les données ont été calculées à l'aide de la version 22.0 du SPSS. Les associations entre les variables ont été testées et multivariées ont été utilisées pour étudier les effets des principales caractéristiques de base sur les résultats de la grossesse. P 0,05 a été considéré statistiquement Important. Résultats: Hyperhomocysteinemia a été enregistré dans 41 (24,6%) Patients. Les femmes à forte concentration d'homocystéine et celles qui un niveau normal d'homocystéine n'a pas différé significativement en termes d'âge (P - 0.684), niveau d'éducation (P - 0.866), et parité (P - 0.647). Femmes l'hyperhomocysteinemia présentait un risque environ douze fois plus élevé de naissance prématurée (P - 0,001) et un risque dix fois plus élevé d'accouchement un terme nouveau-né avec LBW (P - 0,004), mais n'avait aucun risque de mort fœtale antepartum (P - 0,118) par rapport aux femmes ayant une homocystéine normale Concentration. Conclusions: La prévalence de l'hyperhomocysteinemia chez les mères à Lagos était relativement faible. Les associations entre L'hyperhomocysteinemia et les résultats défavorables de grossesse pourraient avoir des implications à l'avenir pour la prévention de ces résultats défavorables.

The prevalence and risk factors for Trichomonas vaginalis infection amongst human immunodeficiency virus-infected pregnant women attending the antenatal clinics of a university teaching hospital in Lagos, South-Western, Nigeria.

BACKGROUND: Trichomonas vaginalis infection is the most prevalent non-viral sexually transmitted infection worldwide. Interactions between this infection and human immunodeficiency virus (HIV) may cause adverse pregnancy outcomes such as preterm labour, premature rupture of membranes, chorioamnionitis, low birth weight and post-abortal sepsis. AIMS: This study was aimed to determine the prevalence and risk factors of T. vaginalis infection amongst HIV-positive pregnant women attending antenatal care at the Lagos University Teaching Hospital (LUTH), Lagos, Nigeria. SUBJECTS AND METHODS: This was an analytical cross-sectional study in which 320 eligible participants which included 160 HIV-positive (case group) and 160 HIV-negative (control group) pregnant women were recruited at the antenatal clinic of LUTH. A structured pro forma was used to collect data from consenting participants after which high vaginal swabs were collected, processed and examined for T. vaginalis. The association between categorical variables was tested using the Chi-square test and Fisher's exact test where applicable. All significances were reported at P < 0.05. RESULTS: The prevalence of T. vaginalis infection amongst HIV-positive and HIV-negative pregnant women were 10% and 8.1%, respectively (P = 0.559). Significant risk factors for T. vaginalis infection in the HIV-positive pregnant women were early coitarche (P < 0.005) and multiple lifetime sexual partners (P = 0.021). There was no relationship between the T. vaginalis infection and the immunological markers of HIV infection. CONCLUSIONS: While this study does not provide grounds for universal screening of pregnant women for T. vaginalis infection as a tool of reducing HIV acquisition, especially in pregnancy, campaign to create better sexual health awareness should be commenced as a way to contributing to the reduction in T. vaginalis infection during pregnancy and perinatal transmission of HIV.

Prevalence and risk factors for genital high-risk human papillomavirus infection among women attending the out-patient clinics of a university teaching hospital in Lagos, Nigeria.

INTRODUCTION: Cervical cancer is the second most common cancer among women in the developing countries and the seventh commonest cancer in the developed countries. Human papillomavirus (HPV) is now known to be the main factor in the aetiology of cervical cancer with over 99.7% of cases being associated with previous high risk HPV (hrHPV) infection. This study was aimed to determine the prevalence and risk factors for genital hrHPV infection among women attending the out-patient clinics of the Lagos University Teaching Hospital. METHODS: This was a cross-sectional study involving a total of 200 women. Questionnaires were administered to collect data such as sociodemographic, reproductive and sexual histories. Endocervical swab samples were then taken from each participant. Samples were analyzed by polymerase chain reaction (PCR) using consensus primers targeted against the hrHPV viruses. RESULTS: The prevalence of hrHPV in the study was 36.5%. The most predominant HPV subtypes were 31 (25.0%), 35 (8.0%) and 16 (3.5%) with the largest proportion (76.1%) of the tested samples being positive for only a single hrHPV subtype. The study showed statistically significant associations between early age at coitarche (P = 0.032) and increasing number of lifetime sexual partners (P = 0.001) with genital hrHPV infection. CONCLUSION: The prevalence of hrHPV was high in Lagos with the majority of test positive samples having only a single HPV genotype. We demonstrated early age of sexual debut and increasing number of lifetime sexual partners as the most important factors associated with genital hrHPV infection.
