Evaluating mean platelet volume and platelet distribution width as predictors of early-onset pre-eclampsia: a prospective cohort study.

BACKGROUND: Platelets are pivotal players in the pathophysiology of pre-eclampsia, with observed lower counts in affected individuals compared to normotensive counterparts. Despite advancements, the elusive cause of pre-eclampsia persists, motivating intense global efforts to identify reliable predictors. The currently recommended predictors of pre-eclampsia are not readily available in many resource-limited regions like Nigeria. This cohort study explores the potential of mean platelet volume (MPV) and platelet distribution width (PDW) as predictive markers of early-onset pre-eclampsia. Both platelet indices are components of the full blood count, a widely available routine test in pregnancy. METHODS: In this prospective cohort study, 648 healthy pregnant women attending antenatal care at Lagos State University Teaching Hospital and General Hospital Ifako-Ijaiye, Lagos, were recruited between 14-18weeks gestational age. Platelet count (PC), MPV and PDW were measured from their venous blood at recruitment. Participants were monitored until 34weeks of gestation, focusing on the occurrence of early-onset preeclampsia as the outcome of interest. Individuals with chronic medical conditions were excluded from the study. Data analysis involved t-test, Chi-Square and Mann-Whitney U tests, with statistical significance set at a confidence level of 95% and p < 0.05. Sensitivity, specificity, and predictive values were determined using receiver operating characteristics (ROC) curves. RESULTS: The incidence of early-onset pre-eclampsia in the study was 5.9%. Women who later developed pre-eclampsia had higher median MPV and PDW at 14-18weeks (10.8 fl. and 24.8 fl.) compared to normotensive women (8.1 fl. and 13.3 fl.)(p < 0.001). The median PC was lower in pre-eclamptics (190 × 103/µl) compared to normotensives(264 × 103/µl)(p < 0.001). Using Youden's test, cut-off values identified: PC < 211.5 × 103/µl, MPV > 9.4 fl., and PDW > 21.3 fl., predicted early-onset pre-eclampsia with 96.6% sensitivity and 65.6% specificity for PC; 79.3% sensitivity and 97.7% specificity for PDW; and 82.8% sensitivity and 96.1% specificity for MPV. Cut-offs of PC < 185 × 103/µl, MPV > 10.7 fl., and PDW > 28.3 fl., predicted severe early-onset pre-eclampsia with 100.0% sensitivity and 90.9% specificity for PC, 100.0% sensitivity and 99.4% specificity for MPV, and 100.0% sensitivity and 99.8% specificity for PDW, with corresponding area under the ROC curves of 0.983, 0.996, and 0.998, respectively. CONCLUSION: The evaluation of MPV and PDW between 14 and 18 weeks of gestation appears to be a reliable predictor of severe early-onset pre-eclampsia.

A decennial cross-sectional review of assisted reproductive technology in a Tertiary Hospital in Southwest Nigeria.

BACKGROUND: The World Health Organization recommends that Assisted Reproductive Technology be complementary to other ethically acceptable solutions to infertility. Whereas fertility centres are increasing in number in urban regions of Africa, published reports of their performance are sparse. We present a 10-year review of assisted reproductive technology performed in a public tertiary centre in Lagos, Nigeria. METHODS: This was a hospital-based, retrospective, cross-sectional review of 604 women, over a 10-year period that had in-vitro fertilization or in-vitro fertilization with intra-cytoplasmic sperm injection at the Institute of Fertility Medicine, Lagos State University Teaching Hospital. Data obtained were expressed in descriptive statistics and Pearson correlation was used to determine the strength of linear relationship between two continuous variables at a significance level of p < 0.05. RESULTS: The mean age of the women was of 37.7 ± 6.2 years and 89.7% had no previous parous experience. About 27.2% of the male partners had normal seminal fluid parameters while 4.6% had azoospermia. Median serum follicle stimulating hormone of the women was 8.1 IU/L and median serum anti-mullerian hormone was 6.3 pmol/L. There was weak positive correlation between age and serum follicle stimulating hormone (r = 0.306, p < 0.001); weak negative correlation between age and serum anti-mullerian hormone (r = -0.48, p < 0.001) and very weak correlation between body mass index and serum follicle stimulating hormone (r = 0.173, p = 0.011). In-vitro fertilization and intra-cytoplasmic sperm injection was the method of fertilization used in 97.4% of the cases and 81.8% of embryos formed were of good quality. Most women (94.5%) had 2 embryos transferred and 89.9% had day-5 embryo transfer done. About 1 in 4 of the women (143/604, 23.7%) had clinical pregnancy and 49.7% of women who got pregnant had delivery of a live baby at term while 11.9% had preterm delivery of a live baby. CONCLUSION: Despite increasing use and success of assisted reproductive technology in south-western Nigeria, there is room for improvement in clinical pregnancy rates and live birth rates post- assisted reproductive technology. Complication rates are desirably low.

Quantitative cervicovaginal fetal fibronectin as a predictor of cervical ripening and induced labour duration in late-term pregnancy.

We evaluated quantitative cervicovaginal foetal-fibronectin as a predictor of cervical ripening and labour duration in late-term pregnant women with an unfavourable cervix. This was an analytical cross-sectional study wherein 152 women, with late-term pregnancy and unfavourable cervix, at 41weeks3days gestational age, had pre-induction quantitative cervicovaginal foetal-fibronectin determined using ELISA. Data were compared in nulliparas and multiparas at a significance level < 0.05. The mean age of late-term pregnant women was 30.4 ± 4.3 years. Median cervicovaginal foetal-fibronectin levels in nulliparous and multiparous women were 45.35 ng/ml and 46.93 ng/ml respectively(p = 0.289). The correlation between foetal-fibronectin levels and cervical ripening duration was poor in nulliparous(r = 0.014) and multiparous(r = 0.024) women. The Youden's foetal-fibronectin cut-off level had a sensitivity of 53.5% and specificity of 71.6% in predicting cervical ripening duration of > 12 hours in late-term pregnancy with an area under the ROC curve of 0.634. Quantitative cervicovaginal foetal-fibronectin is a poor correlate and predictor of cervical ripening and induced labour duration in late-term pregnancy.IMPACT STATEMENTWhat is already known on this subject? Cervicovaginal foetal fibronectin is useful in the prediction of preterm delivery but its role in prolonged pregnancy is unclear.What the results of this study add? Cervicovaginal foetal fibronectin is a poor correlate and predictor of cervical ripening and induced labour duration in late-term pregnancyWhat the implications are of these findings for clinical practice and/or further research? Cervicovaginal fibronectin should not be used to predict ease and success of cervical ripening and induction of labour in women with late-term pregnancy.

Assessment of sublingual misoprostol as first-line treatment for primary post-partum hemorrhage: results of a multicenter trial.

AIM: The study investigated the effectiveness of sublingual misoprostol when used as primary treatment of primary post-partum hemorrhage (PPH) in a low-income country. METHODS: Maternity care providers in three Nigerian hospitals administrated 800 µm sublingual misoprostol to women experiencing PPH. The outcome variables were estimated blood loss and the need for additional uterotonic drugs after initial treatment with misoprostol. Entry criteria included women in term spontaneous labor, while exclusion criteria were women with operative delivery and those experiencing PPH not due to atonic uterus. RESULTS: One hundred and thirty-one women with PPH were treated over 6 months. Estimated blood loss ranged 500-2500 mL. Twenty women (15.3%) required additional uterotonic drugs to control continuing blood loss. There were no maternal deaths, while seven perinatal deaths were recorded. CONCLUSION: We conclude that although sublingual misoprostol is effective in reducing blood loss due to PPH, it does not effectively treat all forms of PPH. Additional uterotonics and other ancillary treatments would be required.

Uterine artery ligation for the treatment of fibroids.

OBJECTIVE: To determine the efficacy of bilateral uterine artery ligation in the treatment of symptomatic uterine fibroids. DESIGN: A descriptive study. SETTING: Tertiary care gynecological clinic, Lagos State University Teaching Hospital, Ikeja, Lagos, Nigeria. SAMPLE: Fifty women who had trans-vaginal bilateral uterine artery ligation for the treatment of uterine fibroids between January 2003 and January 2006. METHODS: Pre-operative baseline ultrasonic measurements of uterine and dominant fibroid volumes were carried out and repeated at two, six, and 12 weeks, then three monthly for a period of three years. Severity of menstrual blood loss, changes in pain symptoms and patients' satisfaction were also assessed. MAIN OUTCOME MEASURES: Changes in uterine and fibroid volumes, hemoglobin values, menstrual pain ratings, and patients' satisfaction ratings. RESULTS: The mean fibroid volume, mean uterine volume, and mean menstrual pain rating showed statistically significant reductions at six, 12, and 36 months. The mean hemoglobin level and patients' satisfaction rating showed a statistically significant increase after six, 12, and 36 months. CONCLUSION: Trans-vaginal bilateral uterine artery ligation is a safe and effective method for the treatment of symptomatic uterine fibroids especially in areas where access to high level medical technology is restricted.

Correlates of abortion related maternal mortality at the Lagos State University Teaching Hospital, Ikeja.

This study was carried out to highlight the probable correlates of mortality among patients managed for abortion related complications at the Lagos State University Teaching Hospital, Ikeja. All patients managed for abortion related complications between 1st January 2000 and 31st December 2003 were studied. Certain relevant socio demographic and clinical factors were compared among the survivors and fatalities. There were a total of 338 patients with abortion related complications. 299 survived while 39 died. Being single, nulliparous, of low educational status, presenting late and having major complications were significantly associated with mortality in this series. Encouragement of safe sex practices, increasing adolescents' access to contraception, additional training of physicians and other appropriate heath workers in abortion care as well as the liberalisation of the restrictive abortion laws in Nigeria will go a long way in reducing abortion related mortality.
