Effects of Vitamin D and E Supplementation on Prevention of Bronchopulmonary Dysplasia (BPD) in Premature Neonates: A Systematic Review and Meta-Analysis.

BACKGROUND: Bronchopulmonary Dysplasia (BPD) has a multifactorial etiology. Vitamin E and vitamin D play an important role in lung development and can potentially be beneficial in the prevention of BPD. OBJECTIVE: The study aimed to compare the risk of BPD occurrence in preterm neonates supplemented with vitamin D or E versus those who did not get supplementation. METHODS: The literature search was conducted for this systematic review by searching the PubMed, Scopus, and Web of Science databases up to December 2022. Randomized controlled trials involved administering vitamin D or E to preterm neonates and examining the occurrence of BPD. We excluded non-English articles, and articles with non-relevant and insufficient data. We used the Critical Appraisal Skills Programme (CASP) checklist to assess the quality of the included studies. We used Egger's test to evaluate the risk of bias among the included studies. Heterogeneity was also assessed through Q-test and I2. We applied the random effect model for analysis. A P-value less than 0.05 was considered as significant. All the statistical analysis in the current study was performed using STATA 14. The Relative Risk (RR) was calculated as the effect size with 95% Confidence Interval (CI). RESULTS: Three eligible studies seeking the role of vitamin D in the prevention of BPD were analysed. Meta-analysis revealed that receiving vitamin D supplementation can significantly reduce the risk of BPD in preterm infants (RR = 0.357, 95% CI: 0.189-0.675, I2 = 0.0%; p = 0.002). Similarly, for assessing the role of Vitamin E in the prevention of BPD, three eligible studies were analysed. Vitamin E supplementation was not found to play a significant role in the reduction of BPD (RR = 0.659, 95%CI = 0.243-1.786, I2 = 38.7%; p = 0.412). CONCLUSION: Vitamin D supplementation could be beneficial in preventing BPD in preterm infants. However, evidence is not enough regarding vitamin E's role in reducing the incidence of BPD in preterm infants.

Role of Oropharyngeal Administration of Colostrum in Very Low Birth Weight Infants for Reducing Necrotizing Enterocolitis: A Randomized Controlled Trial.

OBJECTIVE: This study aimed to study the role of oropharyngeal administration of colostrum (OAC) in very-low-birth-weight infants for reducing necrotizing enterocolitis (NEC). STUDY DESIGN: In this randomized controlled trial, 117 infants were enrolled, 59 were randomized to OAC group and 58 to routine care group. Infants with birth weight ≤ 1,250 g and/or gestational age ≤ 30 weeks were enrolled. Infants in OAC group received maternal colostrum (0.2 mL), 0.1 mL on either side, after 24 hours of postnatal life and were given every 2 hour for the next 72 hours irrespective of the enteral feeding status of the neonate. The primary outcome of the study was the incidence of NEC (stage 2 or 3). RESULTS: Baseline characteristics were comparable between the two groups. There was no significant reduction in the incidence of NEC in OAC group (0 [0%] vs. 3 [7.1%]; p = 0.11). There was significant reduction of 7 days of hospital stay in OAC group (34.2 ± 5.7 vs. 41.5 ± 6.7 days; p = 0.04).The incidence of early-onset sepsis, late-onset sepsis, blood culture positive sepsis, and ventilator-associated pneumonia were comparable between the two groups. CONCLUSION: OAC is safe and reduces the duration of hospital stay.

Neonatal hyperbilirubinemia secondary to combined anti e and anti C isoimmunisation: a literature review.

A term male infant was admitted at 48 h of postnatal life to the neonatal unit for jaundice. The investigation showed total serum bilirubin (TSB) of 17.1 mg/dl, haemoglobin of 11 g/dl, reticulocyte count of 9.5% and peripheral smear was suggestive of macrocytic, normochromic red blood cell (RBC) with target cells and multiple spherocytes with occasional nucleated RBC. The infant's blood group was B positive. Direct antiglobulin test was strongly positive by gel method (3+). Mother's blood group was B positive and indirect antiglobulin test was positive when tested postnatally. Extended minor blood grouping and cross matching showed this as a case of combined anti e and anti C antibodies isoimmunisation. Infant was treated with phototherapy for 72 h and was shifted to mother side. Infant was serially monitored with TSB level every sixth hourly and American Academy of Pediatrics (AAP) phototherapy charts were followed to see for rebound hyperbilirubinemia. The neonate was discharged and there was no readmission for hyperbilirubinemia. It is very rare and we report the third case of its type till date.

Role of oral zinc supplementation for reduction of neonatal hyperbilirubinemia: a systematic review of current evidence.

BACKGROUND: Neonatal hyperbilirubinemia is frequently seen condition in the NICU. Oral zinc has been tried for the prevention of hyperbilirubinemia. AIMS: To evaluate the role of oral zinc supplementation for reduction of neonatal hyperbilirubinemia in term and preterm infants. METHOD: The literature search was done for various randomized control trial (RCT) by searching the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, Scopus, Index Copernicus, African Index Medicus (AIM), Thomson Reuters (ESCI), Chemical Abstracts Service (CAS) and other data base. RESULTS: This review included six RCT that fulfilled inclusion criteria. One study evaluated the role of zinc in very low birth weight (VLBW) infants and remaining enrolled neonates ≥35 weeks of gestation. The dose of zinc varied from 5 to 20 mg/day and duration from 5-7 days. All the studies used zinc sulfate, only one study used zinc gluconate. The total neonates enrolled in these different RCT are 749. CONCLUSION: Role of zinc in the prevention of neonatal hyperbilirubinemia is not supported by the current evidence. Only one study was able to show reduction in the mean TSB level and requirement of phototherapy with zinc, and the remaining studies did not report any positive effect. None of the studies showed any effect on the duration of phototherapy, incidence of phototherapy, age of starting of phototherapy and any serious adverse effect.
