Acute kidney injury among critically ill neonates in a tertiary hospital in Tanzania; Prevalence, risk factors and outcome.

BACKGROUND:Neonatal acute kidney injury contributes to high mortality in developing countries. The burden of neonatal AKI is not known in Tanzania despite having high neonatal mortality. This study was conducted to determine the burden of AKI among critically ill neonates admitted at Muhimbili National Hospital. METHODS:This was a cross-sectional study conducted in the neonatal ward at the MNH. Eligible critically ill neonates were recruited consecutively between October 2017 and March 2018. Data was collected using a standardized structured questionnaire. Blood specimen was drawn to measure baseline creatinine at admission, 48th hour, 72nd hour and 14th day. Data was analysed using SPSS version 20.0 Univariate analysis was done using chi-square to determine the association between categorical variables and multivariate logistic regression was performed to determine predictors of AKI. RESULTS:A total of 378 critically ill neonates were recruited, 31.5% had AKI and independent predictors of AKI were noted to be neonatal sepsis (aOR 2.237, 95%CI 1.3-3.6, P = 0.001), severe pneumonia (aOR3.0, 95%CI 1.0-9.3, P = 0.047) and use of gentamycin (aOR6.8, 95%CI 1.3-9.3, P = 0.02). Complete resolution of renal dysfunction at the fourteenth day was seen in 83.1% of the neonates while 16.9% had persistence of renal dysfunction. Ultrasound scan were performed among 105 participants with AKI revealed increased echogenicity, mild hydronephrosis and ectopic kidneys in 25 (23.8%), 4 (3.8%) and 2 (1.9%) respectively. In-hospital mortality was significantly higher among neonates with AKI (70.6%) as compared to those without (29.4%) p< 0.001. CONCLUSIONS:AKI was noted in a third of critically ill neonates, with neonatal sepsis, severe pneumonia and use of gentamycin as independent predictors of AKI. Neonates who suffered AKI had twice as much mortality as compared to those without

Late diagnosis of congenital diaphragmatic hernia: a case report

Background Congenital diaphragmatic hernia beyond the neonatal period is not uncommon. Its diagnosis in infancy and early childhood poses a challenge owing to different clinical presentation ranging from gastrointestinal to respiratory symptoms. These neonates are usually misdiagnosed as having pneumonia until radiological imaging picks up the defect during routine scan for worsening respiratory symptoms. In high-income countries, the survival rate for these patients has been reported to be high, while in Sub-Saharan Africa the survival rate is still low due to delayed diagnosis, delayed referral, and hence delayed management. Case report We present an African male baby from non-consanguineous parents, 6 weeks old, diagnosed with congenital diaphragmatic hernia at 6 weeks of age after failure to respond to antibiotics for suspected pneumonia. Despite attempts at management, he died at 5 weeks post surgery. Conclusion Our case emphasizes the importance of early clinical suspicion and early detection for a differential diagnosis of congenital diaphragmatic hernia in infants who present with respiratory symptoms not responding to antibiotics or recurrent pneumonia, and improving the availability of imaging in primary care facilities to diagnose such defects early and manage them accordingly

Esophageal atresia with tracheoesophageal fistula: two case reports

Abstract Background The incidence of esophageal atresia with tracheoesophageal fistula is 1 out of 3000–5000 live births. Its incidence in lower middle income countries is not known. The infants usually present with excessive secretions or choking while feeding and are at risk for aspiration. The outcome of these infants in lower middle income countries is not encouraging due to delays in referral, sepsis at presentation requiring preoperative stabilization, postoperative complications such as anastomosis leaks, pneumonia, and pneumothorax. Case presentation We present two African babies who were term infants at age 2 days (male) and 5 days (female) with diagnosis of esophageal atresia and tracheoesophageal fistula. The 5-day-old infant required preoperative stabilization due to sepsis and delayed surgery with a poor postoperative outcome. The 2-day-old infant was preoperatively stable and had a good postoperative outcome. The challenges faced in management of these two cases have been highlighted. Conclusion Outcome of infants with esophageal atresia and tracheoesophageal fistula in lower middle income countries is not encouraging due to delays in referral and poor postoperative healing attributed to sepsis and recurrent pneumothorax. Timely referral, preoperative condition of the infant, and timely management has shown to be a contributory factor for an improved outcome
