RESUMO

Introduction: effective COVID-19 vaccines for the prevention of severe illness have been available for more than one year now. This study was carried out to ascertain vaccine hesitancy and its associations among pregnant women receiving antenatal care in Port Harcourt, a large cosmopolitan town in Nigeria. Methods: we conducted a cross-sectional online survey over 2 months among consenting pregnant women receiving antenatal care in the 3 largest obstetric service centers in Port Harcourt to evaluate COVID-19 vaccine hesitancy and its associations. Results: the prevalence of vaccine hesitancy was 669 (72.2%). Of the respondents, 27 (2.9%) had been infected or had a close family member infected with SARS-CoV-2, and 897 (96.8%) of them had heard of the COVID-19 vaccine; however, only 133 (14.4%) had been vaccinated against COVID-19. The safety of the mother in 260 (32.8%) and the safety of the unborn baby in 114 (14.4%) of the respondents were the reasons for vaccine hesitancy. A small proportion of women 7(0.9%) were hesitant on religious grounds. Tertiary education, use of childhood immunization for previous infants delivered, and availability of COVID-19 vaccine in the antenatal clinic at no cost to the women, were statistically significant predictors of vaccine uptake among the respondents. Conclusion: the prevalence of vaccine hesitancy among pregnant women in Port Harcourt was 72.2%. Higher academic achievement and availability of the COVID-19 vaccine in the antenatal clinic were predictors of vaccine uptake, while reasons for hesitancy were mostly due to safety concerns for the mother and unborn baby.

RESUMO

Background: The study was prompted by the high prevalence of hyperglycaemia first detected in pregnancy (HIP) which is classified into diabetes mellitus in pregnancy (DIP) and gestational diabetes mellitus (GDM). This study aimed to determine the usefulness of Glycosylated Haemoglobin (HBA1c) in the diagnosis of HIP in the first trimester of pregnancy. Methodology: The study was of a prospective cross-sectional design carried out between January 2020 and August 2020 at the University of Port Harcourt Teaching (UPTH) and Rivers State University Teaching Hospital (RSUTH). Three hundred and five consecutive pregnant women attending the antenatal clinic at 8 to 13 +6 weeks of pregnancy were recruited for the study. Patients' socio-demographic information, anthropometric measurements, and medical, obstetric, and gynaecological history were recorded on a predesigned proforma. Blood was taken for an oral glucose tolerance test (OGTT) and glycosylated haemoglobin (HBA1c) levels. Ethical approval for the study was obtained from the Research Ethics Committee of the UPTH and RSUTH. Results: The prevalence of DIP, GDM, and HIP in the study was 2.62%, 28.85%, and 31.48% respectively. The ROC curve for HbA1c in the study showed a significant area under the Curve (AUC) value of 0.653%, 95% CI = 0.59 - 0.72, p = 0.001. The Youden index reached 2.50 and the optimal cut-off for HBA1c for diagnosis of diabetes was 5.25%. The sensitivity, specificity, PPV, and NPV for HbA1c against the Gold standard OGTT in the diagnosis of GDM were 36.5%, 88.5%, 59.3, %, and 75.2% respectively. HbA1c had high specificity and moderately high NPV. Conclusion: Glycosylated haemoglobin was a fairly good tool for diagnosis of HIP in the first trimester, but it could not replace OGTT which is the gold standard.

RESUMO

Background: Vaginal infections constitute a significant health challenge for women and lead to long-term complications if not promptly and adequately treated. We aimed to determine the prevalent organisms in vaginal infections in our women and the antibiotic susceptibility of the offending organisms. Methodology: This was a prospective cross-sectional study of 635 consecutive women attending the Obstetrics and Gynaecology clinic of the University of Port Harcourt Teaching Hospital from 1st January 2017 to 31st December 2018. Data obtained were analysed using SPSS version 19. Results: Four hundred and eight (64.3%) of the women were gynaecological patients, while the remaining 227 (35.7%) were obstetric patients. One hundred and ninety-one(30.1%) out of the total 635 study population did not have any growth of the organisms tested for in the culture assay, while the remaining 444 (69.9%) had. One hundred and forty-four of the women(22.2%) had growth of candida Albicans, 130 (20.5%) had staphylococcus aureus, 78 (12.3%) - Klebsiella species (spp), 48 (7.6%) - Escherichia coli, 30 (4.7%) - Pseudomonas species, 8 (1.3%) - Proteus species and 6 (0.9%) of the women had Streptococcus species. The commonest pathogen involved in vaginal infections in women was Candida albicans. The commonest bacterial isolate was Staphylococcus aureus and then Klebsiella species. The bacteria were susceptible to Ceftriaxone, Cefpodoxime, Cefotaxime, Cefixime, Ciprofloxacin, Dorepenem and Ampicillin. They were mainly resistant to cefuroxime, ceftazidime, Augmentin, Erythromycin and Meropenem. Conclusion: Candida albicans is prevalent in our women. Staphyloccocus aureus is the commonest bacterial organism in women with vaginal infections. Empirical antibiotic treatment using Cetriazone, Cefpodoxime and Ciprofloxacin, available in our setting, may be beneficial while awaiting the culture results in women with suspected vaginal infections.

RESUMO

Background: Gestational Diabetes Mellitus (GDM) is a common metabolic complication in pregnancy with a broad range of adverse foetal and maternal outcomes if not properly managed. Due to the difficult nature of the Oral glucose tolerance test (OGTT), the utilization of the Glycatedhaemoglobin (HbA1c) test as a simpler and acceptable alternative has been suggested. The aims were to determine the GDM prevalence, the diagnostic accuracy, the optimal cut-off point and the validity of the HbA1c in diagnosing GDM using OGTT as the gold standard in the University of Port Harcourt Teaching Hospital (UPTH). Methodology: This was a prospective cross-sectional study involving a cohort of 250 antenatal attendees at 24-28 weeks of pregnancy in the UPTH from 1st February 2018 - 30th April 2018. Socio-demographic data and results of the OGTT and HbA1c tests were analysed using SPSS 21.0 for windows® statistical software. The area under the Receiver Operating Characteristics (ROC) curve was used to determine the diagnostic accuracy of HbA1c. The Youden index was used to get the optimal cut-off point for HbA1c. The validity of the HbA1c was determined using sensitivity, specificity, positive predictive value and negative predictive value. The P-value at p<0.05 was set as the level of significance. Results: Out of the 250 women, 36 (14.4%) had GDM hence in this study, the GDM prevalence was 14.4%. Area under the curve (AUC) = 0.649; 95% confidence interval: 0.550 - 0.748; p-value = 0.004. The optimal cut-off point for HbA1c was 5.18% with a sensitivity of 63.9%, a specificity of 59.3%, a positive predictive value of 20.9% and a negative predictive value of 90.7%. Conclusion: The HbA1c at the Optimal cut-off point of 5.18% in our environment cannot replace the OGTT in the diagnosis of GDM because of its low sensitivity and specificity but will be useful in the screening for GDM because of its high negative predictive value at 24-28 weeks gestation. This will reduce the count of gravidae who undergo the cumbersome OGTT.
