Maternal morbidity and death associated with pregnancy loss before 28 weeks in Nigeria.

OBJECTIVE: To determine the prevalence of maternal morbidity and death from pregnancy loss before 28 weeks in referral-level hospitals in Nigeria. DESIGN: Secondary analysis of a nationwide cross-sectional study. SETTING: Fifty-four referral-level hospitals. POPULATION: Women admitted for complications arising from pregnancy loss before 28 weeks between 1 September 2019 to 31 August 2020. METHODS: Frequency and type of pregnancy loss were calculated using the extracted data. Multilevel logistic regression was used to determine sociodemographic and clinical factors associated with early pregnancy loss. Factors contributing to death were also analysed. MAIN OUTCOME MEASURES: Prevalence and outcome of pregnancy loss at <28 weeks; sociodemographic and clinical predictors of morbidity after early pregnancy loss; contributory factors to death. RESULTS: Of the 4798 women who had pregnancy loss at <28 weeks of pregnancy, spontaneous abortion accounted for 49.2%, followed by missed abortion (26.9%) and ectopic pregnancy (15%). Seven hundred women (14.6%) had a complication following pregnancy loss and 99 women died (2.1%). Most complications (26%) and deaths (7%) occurred after induced abortion. Haemorrhage was the most frequent complication in all types of pregnancy loss with 11.5% in molar pregnancy and 6.9% following induced abortion. Predictors of complication or death were low maternal education, husband who was not gainfully employed, grand-multipara, pre-existing chronic medical condition and referral from another facility or informal setting. CONCLUSION: Pregnancy loss before 28 weeks is a significant contributor to high maternal morbidity and mortality in Nigeria. Socio-economic factors and delays in referral to higher levels of care contribute significantly to poor outcomes for women.

Correlation of perinatal outcomes with amniotic fluid assessment techniques in high-risk pregnancies in a Tertiary Hospital in Southern Nigeria.

BACKGROUND: Oligohydramnios is a predictor of fetal compromise and a useful tool in pregnancy management. It has been assessed using various techniques, including two-diameter pocket (2-DP) and amniotic fluid index (AFI). OBJECTIVES: To determine which of these two techniques best diagnose oligohydramnios and predicts adverse perinatal outcomes. METHODS: This was a comparative cross-sectional study conducted at Delta State University Teaching Hospital, Oghara in southern region of Nigeria over eight months period. One hundred high-risk pregnant women were recruited and ultrasound determination of amniotic fluid was performed using AFI and 2-DP. The women were followed up till delivery to determine adverse perinatal outcomes. RESULTS: The indices of validity of AFI and the 2-DP were calculated and compared. The 2-DP had a higher sensitivity than AFI for adverse outcomes in high-risk pregnancies complicated by oligohydramnios. CONCLUSION: The 2-DP technique should preferably be used for the assessment of oligohydramnios in high-risk pregnancies.

Clinical and sociodemographic correlates of preterm deliveries in two tertiary hospitals in southern Nigeria.

BACKGROUND: To determine the prevalence of preterm delivery and identify the associated risk factors. DESIGN: This was a five - month prospective case control study of two cohorts of women who had preterm and term deliveries. SETTING: Central Hospital (CH), Warri, and Delta State University Teaching Hospital (DELSUTH), Oghara, respectively in southern Nigeria. PARTICIPANTS: 522 women which consisted of 174 who presented in preterm labour or with preterm prelabour rupture of membranes as cases and 348 parturient with term deliveries served as controls. INTERVENTIONS: The study was conducted from May 1st 2015 to September 30th 2015. Socio - demographic characteristics, past gynaecological/obstetric factors, maternal/obstetric factors, and fetal outcomes were compared, and associations between these variables and gestational age at delivery were determined. MAIN OUTCOME MEASURES: Prevalence of preterm delivery associated clinical and socio-demographic correlates and the fetal salvage rates. RESULTS: The incidence of preterm birth was 16%. Maternal age (p < 0.002), parity (p < 0.000), booking status (p < 0.000), and socio - economic class (p < 0.000) were significantly associated with preterm births. Others were multiple pregnancy (p < 0.000), pre - eclampsia/eclampsia (p < 0.000), anaemia (p < 0.000), malaria (p < 0.000), UTI (p < 0.012), premature rupture of membrane (p < 0.000) and antepartum haemorrhage (p < 0.000). Fetal salvage rate was zero for extreme preterm neonates and 100% at late preterm. CONCLUSION: Preterm birth was common, with well-defined correlates and predictors. The fetal salvage rates were significantly different across the categories of preterm neonates. FUNDING: The study was self-funded by the authors.

The challenges of diagnosis and treatment of malaria in pregnancy in low resource settings.

Malarial infestation in pregnancy is a major public health concern in endemic countries and ranks high amongst the commonest complications of pregnancy, especially in large areas of Africa and Asia. It is an important preventable cause of significant maternal morbidity and mortality with associated fetal as well as perinatal wastage. The burden of malaria is greatest in sub-Saharan Africa where it contributes directly or indirectly to maternal and perinatal morbidity and mortality. The need for prompt and accurate diagnosis as well as prevention and treatment of malaria during pregnancy cannot, therefore, be overemphasized. This commentary focuses on the challenges of diagnosis and treatment of malaria in pregnancy.

Maternal mortality at the Central Hospital, Benin City Nigeria: a ten year review.

Maternal mortality remains a major challenge in Nigeria. This retrospective study was conceptualized to document the number and pattern of obstetric deaths at the Central Hospital, Benin City, over a ten year period, to identify common causes of maternal deaths and proffer relevant interventions. The overall maternal mortality ratio (MMR) was 518/100,000. MMR was 30 times higher in unbooked as compared to the booked patients, while 60% of maternal deaths occurred within 24 hours of admission. The leading direct causes of maternal deaths were sepsis, hemorrhage, obstructed labor and preeclampsia/eclampsia, while the major indirect causes are institutional difficulties and anaemia. Low literacy, high poverty levels, extremes of parity and non-utilization of maternity services were associated with maternal mortality. Recommendations are made for public enlightenment campaign and advocacy activities aimed at mobilizing resources for reducing maternal mortality. Also, female education and poverty alleviation programmes will contribute to the reduction of the burden of maternal mortality.

Association of Chlamydia trachomatis serology with tubal infertility in Nigerian women.

AIM: To determine the association between tubal infertility and Chlamydia trachomatis in Nigerian women. METHODS: This case-control study is from the Departments of Obstetrics and Gynecology of two tertiary hospitals in Nigeria. One hundred and sixty-two infertile patients with tubal occlusion had 162 pregnant women matched for age as controls. Information on sociodemographic variables, sexual and reproductive risk factors, and history of previous pelvic infections were elicited using a study protocol. The prevalence of Chlamydia Trachomatis antibody was determined for cases and controls. RESULTS: The prevalence of serum Chlamydia antibody was significantly higher in cases (65.8%) compared with controls (17.3%; P < 001). The effects of Chlamydia antibodies on infertility were strengthened in the multivariate model controlling for Chlamydia antibodies and gynecologic symptoms, compared to the univariate model. However, the association was attenuated and non-significant when the effects of gynecologic symptoms, sociodemographic characteristics, contraceptive and sexual history were controlled in the conditional logistic regression model. The strongest independent predictors of infertility in the model were vaginal discharge, education less than tertiary and more than three lifetime sexual partners (proxies of sexually transmitted infections). CONCLUSIONS: There was no strong independent association between Chlamydia antibodies and the risk of being infertile in Nigerian women. By contrast, the proxies of sexually transmitted infections were significant predictors of infertility in the women. Efforts to address these factors, which are proxies of sexually transmissible infections, Chlamydia infection, and health-seeking behavior for these infections, will likely contribute to reducing the burden of infertility in Nigerian women.
