Literature on the subject is still poorly documented in the African setting. Objective: The aim of this study was to determine the maternal and fetal outcomes in case of meconium stained amniotic fluid observed during term labour. Materials and Methods: We conducted a prospective cohort study enrolling all consenting pregnant women with term singleton fetus in cephalic presentation admitted for labour with ruptured fetal membranes in the maternity units of the Yaoundé Central Hospital (YCH) and the Yaoundé Gynaeco-Obstetric and Pediatric Hospital (YGOPH) of Cameroon between December 2014 and April 2015. The exposed grouped was considered as participants having MSAF, while the non-exposed group comprised those with clear amniotic fluid (CAF). The two groups were monitored during labor using the WHO partograph, and then followed up till 72 hours after delivery. Variables studied included the colour and texture of amniotic fluid as well as maternal and fetal complications. Data was analyzed using Epi-info version 3.5.4. The chi-square and Fischer’s exact tests were appropriately used to compare the two groups. A p-value less than 5% was considered statistically significant. Results: 2376 vaginal deliveries were recorded during the study period among which MSAF was observed in 265 cases, hence a prevalence rate of MSAF of 11.15%. Among these cases of MSAF, 52.1% was thick meconium and 47.9% was light meconium. Maternal morbidity was high in the group with MSAF;these included: Higher proportions of caesarean delivery (RR = 2.35 p -4) and prolonged labor (RR = 3 p -4). In this same group, the incidences of chorioamnionitis and puerperal sepsis were low (0.94% and 0.70% respectively), although there was a three-fold higher risk that was not statistically significant (RR = 3, P = 0.31). Fetal and neonatal outcomes were poorer in the MSAF group compared to the CAF group. The complications included fetal heart rate abnormalities, low Apgar score at the 5th minute, need for neonatal resuscitation, neonatal asphyxia and neonatal infection which were significantly higher in the MSAF group (all p < 0.05). Meconium aspiration syndrome (MAS) was found in 2.34% of MSAF cases. Perinatal mortality was 2.34% and all cases of death occurred in the thick MSAF group. Conclusion: MSAF observed during labour is associated with increased perinatal morbidity and mortality. Its detection during labor should strongly indicate very rigorous intra partum and postpartum monitoring. This will ensure optimal management and reduction in the risks of complications.展开更多

Alveolar epithelial...Background and objectives: In prior studies we demonstrated that meconium-induced lung cell death by apoptosis was associated with activation of the local pulmonary renin-angiotensin system (RASL). Alveolar epithelial apoptosis requires the authocrine synthesis and proteolytic processing of angiotensinogen (AGT) to Angiotensin II (ANG II). Inhibitors of angiotensin converting enzyme (ACE) block meconium-induced apoptosis. ANG II plays an essential role in vascular homeostasis and lung injury. The objectives of this study were to evaluate expression of AGT, ANG II and Caspase 3 in meconium and saline treated newborn lungs and to study mechanisms of its inhibition by a selective antagonist of the AT1 receptor. Methods: Two week old rabbits were studied. Three treatment groups were studied (six rabbit pups in each group): Group 1: rabbits instilled with saline;Group 2: rabbits instilled with 10% meconium;Group 3: Losartan pretreated followed by meconium-instillation. Three groups of A549 human lung epithelial cells were studies as well. Group 4: AGT pretreated and then meconium-exposed cells;Group 5: ANG II pretreated and then meconium exposed cells and Group 6: Caspase 3 inhibitor ZVAD-fmk pretreated and then meconium exposed cells. AGT, ANG II and Caspase 3 were evaluated and compared with and without inhibitors in meconium and control groups. Results: In Situ End Labeling (ISEL) and Caspase 3 assays showed that purified ANG II induced dose dependent apoptosis in rabbit lung lavage cells and the human A549 lung epithelial cell line. Apoptosis also was induced by purified AGT. The increase in apoptotic cells was accompanied by increases in ANG II and Caspase 3 activities. In both airway epithelium and alveolar wall cells, measures of apoptosis were attenuated by Losartan or by the Caspase 3 inhibitor ZVAD-fmk. Conclusions: These data demonstrate the presence of a functional ANG II and Caspase 3 dependent apoptotic pathways in newborn meconium-instilled lungs. They also imply that meconium-induced apoptosis is modulated by the pulmonary RASL system in which ANG II plays a critical role. Both losartan and the Caspase 3 inhibitor ZVAD-fmk pretreatment significantly decreased meconium-induced Caspase-3 activation and lung cell apoptosis.展开更多

Capto-pril was a strong inhibitor of meconium-induced lung injury, inflammation and apoptosis and reduces lung alveolar and airway epithelial cell damage. Presently we demonstrate that IL-13 expression in the me-conium aspiration syndrome (MAS). IL-13 was maximally expressed 8 hrs after meconium instilla-tion. It was previously described that IL-13 plays a major role in degradation of airway epithelial cells and inducing of lung fibrosis by activating collagen production that is a major point in identification of lung fibrosis. We also showed that Captopril treat-ment significantly inhibits IL-13 expression in the lungs. We believe it reduces meconium-induced lung injury and has a therapeutic effect on histological and biochemical functions of the lungs and possibly pulmonary fibrosis. Captopril treatment significantly reduced the number of neuprophils and macrophages which express IL13 and levels of other inflammatory cytokines after meconium instillation. Selective neu-tralization of IL-13 ameliorated lung injury, airway hyper responsiveness, eosinophil recruitment and mucus overproduction.展开更多

Methods: We reviewed the obstetric records of all Japanese singleton deliveries after 22 weeks’ gestation managed at Japanese Red Cross Katsushika Maternity Hospital between 2002 and 2008 (n = 11,249). Results: The incidence of MSAF in the whole singleton pregnancies was 13%. The incidence of MSAF at preterm, term and post-term were 9.1%, 13% and 48%, respectively. The incidence of intrauterine fetal death, low Apgar score and low umbilical artery pH at delivery in cases with MSAF were significantly higher than those without MSAF in various gestational ages at delivery. Conclusion: Obstetric management should be affected by meconium in the amniotic fluid.展开更多

Methods Eighty-one severe MAS cases intervened by the mechanical ventilation from 9 childrens hospitals were retrospectively analyzed for the risk factors of fatality with SAS software for non-parametric rank sum test and chi-square test. Results In the 81 cases, 49 were survived (death rate 39%). The gestational age (GA), Apgars score at 1min and other complications with MAS were significantly related to the death (P <0.05). There was no difference of death rate between the patients with or without receiving endotracheal intubation and airway suctioning (P>0.05). Conclusion A higher death rate (close to 40%) of severe MAS in the middle of 1990s in major cities of China suggests that it is important to detect the intrauterine hypoxemia as it may indicated by meconium staining amniotic fluid which should be intervened early by adequate termination of pregnancy before 42 weeks. The effects of delivery room suction and conventional ventilation also need to be reevaluated.展开更多
