Vitamin D Levels in Mother-Baby Pairs: A Cross-Sectional Prospective Study in a Rwandan Tertiary Hospital.

BACKGROUND: Exposure to the sunlight contributes largely to the production of vitamin D. However, vitamin D deficiency is a reality in tropical countries, despite enjoying enough sunlight, especially bearing women in their last trimester whose foetuses exclusively depend on their reserves. This work aimed at demonstrating the state of vitamin D in mother-baby pairs and associated factors in one of the University Hospitals in Rwanda. METHODS: This cross-sectional prospective study was performed on mother-baby pairs at Kigali University Hospital. Mother's serum 25-hydroxyvitamin D levels were considered as outcomes compared with demographic, clinical and biological markers. Correlation analysis was conducted in order to assess the association between serum 25-hydroxyvitamin D levels for the couple mothers-babies. RESULTS: Approximately 38% of women and 65% of neonates had deficiency in 25-hydroxyvitamin D (<20 ng/ml). The use of a vitamin D rich diet within 24 h recall (p < 0.01) or 1 week recall (p < 0.001) before delivery was associated with appropriate vitamin D levels in mothers. Interestingly, a strong positive correlation was found between maternal and neonatal serum 25-hydroxyvitamin D levels (r = 0.760). CONCLUSIONS: There was a high rate of vitamin D deficiency in mothers and their babies. Babies born from women with deficiency were likely to develop low levels of vitamin D. This stresses on the need to strengthen the interventions for preventing vitamin D deficiency in the couple mothers-babies such as supplement in vitamin D before and after delivery, improving the quality of meals and regular contact with sunlight.

Prevalence, risk factors and outcomes of neonatal hypothermia at admission at a tertiary neonatal unit, Kigali, Rwanda - a cross-sectional study.

INTRODUCTION: Thermoregulation remains a key physiological challenge faced by a neonate after delivery. We assessed the prevalence, risk factors and outcomes of hypothermia in admitted neonates at a tertiary teaching hospital of Kigali city in Rwanda. MATERIALS AND METHODS: A cross-sectional study was conducted, from July 2013 to September 2017, of neonates who were admitted in the neonatology unit of the University Teaching Hospital of Kigali (CHUK) and whose admission temperature were recorded. Data were extracted from the neonatal database (registry). RESULTS: The neonatal database contained 1021 eligible neonates of which 15% were outborn. Hypothermia was found at admission in 280 of the 1021 eligible neonates (27%). The extremely preterm (<28 weeks) were significantly more likely to become hypothermic compared to term neonates (AOR = 6.81, CI: 3.39-13.71, p < .001). Mortality rate was higher in hypothermic infants (AOR = 1.89, CI: 1.16-3.1, p = .011). Length of hospital stay (22 versus 13 days, p < .001), in all surviving infants was higher in neonates admitted hypothermic, though not in the subgroups of infants < 32-week gestation. DISCUSSION: Thermal protection of the neonate immediately after birth is essential. In our tertiary neonatal unit, we identify nearly one-third of neonates are hypothermic at admission and this is associated with higher mortality and increased length of hospital stay. The ten-steps of the WHO "warm chain" may present an analytic roster for maternity and neonatal teams to pinpoint targets for interventional research and quality improvement work in order to achieve better outcomes.

Establishing a neonatal database in a tertiary hospital in Rwanda - an observational study.

Background: Monitoring and evaluation is vital in the quest to improve the quality of care and to reduce the morbidity and mortality of neonates in a resource-limited setting. Databases offer several advantages such as data on large cohorts of neonates and from multiple centres. Aim: To establish a minimal dataset neonatal database in Kigali, Rwanda and to assess the quality and timing of the data entry process. Secondary objectives were to describe survival rates and associated risk factors. Methods: A cross-sectional, observational study was undertaken at a tertiary hospital in Kigali, Rwanda. The Rwanda Neonatal Data Collection Form was designed specifically for the database, based on the Vermont-Oxford Network neonatal data-collection tool with locally relevant amendments. All admitted neonates were enrolled during the study period of 2011-2017 with ongoing data-collection. Infants were recruited and data collected prospectively and cross-checked retrospectively with the inclusion of basic data on neonates who were not initially recruited prospectively. Results: 3391 analysable cases were recruited: 1420 prospective and 1971 retrospective cases. Prospective data collection peaked at 90%. Data entry was not always complete with data-points left blank with only 21% having adequate data available (0-25% missing). All-cause mortality during the study period was 16% and annual mortality ranged from 12% to 24%. On multivariate analysis, place of birth (AOR 2.17), small-for-gestational-age (AOR 2.05) and gestational age were all positively associated with survival. Conclusions: An academic setting in a low- or middle-income country can create and maintain a neonatal database without funding and produce a wealth of actionable results. Throughout the process, there were considerable challenges which must be addressed if such a database is to be optimised, maintained and created in other clinical sites.

Pattern of congenital heart diseases in Rwandan children with genetic defects.

INTRODUCTION: Congenital heart diseases (CHD) are commonly associated with genetic defects. Our study aimed at determining the occurrence and pattern of CHD association with genetic defects among pediatric patients in Rwanda. METHODS: A total of 125 patients with clinical features suggestive of genetic defects were recruited. Echocardiography and standard karyotype studies were performed in all patients. RESULTS: CHDs were detected in the majority of patients with genetic defects. The commonest isolated CHD was ventricular septal defect found in many cases of Down syndrome. In total, chromosomal abnormalities represented the majority of cases in our cohort and were associated with various types of CHDs. CONCLUSION: Our findings showed that CHDs are common in Rwandan pediatric patients with genetic defects. These results suggest that a routine echocardiography assessment combined with systematic genetic investigations including standard karyotype should be mandatory in patients presenting characteristic clinical features in whom CHD is suspected to be associated with genetic defect.
