Abstract
BACKGROUND: Vitamin D deficiency in neonates is associated with neonatal sepsis incidence. It is also significantly correlated to the increased risk in the outcomes of sepsis, such as mortality, length of hospital stay, and use of ventilatory support.
AIM: The aim of the study is to observe the relationship between Vitamin D levels and clinical outcomes of sepsis in the neonatal unit.
METHODS: An analytical cross-sectional study was conducted to neonates in neonatology Haji Adam Malik hospital from June 2019 to February 2020. A Chi-square test was carried out to observe the relationship between Vitamin D levels and sepsis outcomes, and a Mann-Whitney test was done to assess the significance between Vitamin D levels and length of hospital stay.
RESULTS: Among 41 full-term and pre-term neonates, there were 75.6% (31/41) neonates with Vitamin D deficiency, while 24.4% (10/41) had normal Vitamin D levels and did not suffer from deficiency. The relationship of Vitamin D levels with mortality, use of ventilatory support, length of stay, and blood culture was p = 0.660 (95% confidence interval [CI] = 0.810–1.677), p = 0.013 (p < 0.05), p = 0.940 (median 21 days), and p =0.712 (95% CI = 0.623–1.353), respectively.
CONCLUSION: Vitamin D deficiency had a significant relationship with ventilatory support requirement as one of the sepsis outcomes in neonates.

Abstract
Background: Vitamin D has regulatory effects on different cells of the immune system and low levels are associated with several immune-mediated diseases. Aim: To investigate the association between neonatal 25-hydroxy vitamin D (25-OHD) level and the expression of lymphocyte activation markers (HLA-DR, CD69, CD25, CD45RA) on T-lymphocyte subpopulations and its impact in neonatal infection. Methods: 25-OHD level was measured in the cord blood of 56 neonates and their mothers using an enzyme immune-assay method. Based on the 25-OHD level, infants were categorised into four groups: severe deficiency (n = 7), moderate deficiency (n = 21), mild deficiency (n = 15) and normal 25-OHD level (n = 13). Mothers were classified into deficient (n = 18), insufficient (n = 21) and normal levels (n = 17). T-lymphocyte subpopulations and lymphocyte activation markers were investigated using flow cytometry. Results: There was a positive correlation between maternal and cord blood 25-OHD levels (r = 0.503, p = 0.001). The group with severe 25-OHD deficiency had the significantly lowest level of total lymphocytes, CD3+ T lymphocytes, CD4+ T-helper and CD8+ T-cytotoxic lymphocytes and CD4+CD45RA+ naïve T-cells compared with the other groups. The frequencies of CD8+CD25+, CD4+CD25+ and CD4+HLA-DR+ activated T-lymphocytes were significantly lower in the severe, moderate and mild deficiency groups than in the normal group. Seven of 43 (16.27%) infants with 25-OHD deficiency were admitted with sepsis to the neonatal intensive care unit and there were no cases of sepsis in the normal 25-OHD group. Conclusion: Vitamin D deficiency is associated with a reduction of lymphocyte subsets and altered T-lymphocyte activation which are considered to be risk factors for neonatal infection.

Abstract
OBJECTIVE To explore the predictive value of cord blood 25(OH)D3 [25(OH)D3] for infantile atopic dermatitis (AD), and to provide a reference for primary prevention of early infantile AD. METHODS The neonates born from July to September, 2015 were enrolled. The cord blood samples were collected at birth to measure the level of 25(OH)D3. Outpatient follow-up was conducted for all the infants at 6 weeks, 3 months, and 6 months after birth. A survey was performed to investigate the incidence of AD. RESULTS A total of 67 neonates completed a 6-month follow-up. The incidence of AD was 34% (23/67), and 91% (21/23) of these cases occurred in the first month after birth. The 23 AD children had a significantly lower cord 25(OH)D3 level than those without AD (P<0.05). The children with a cord 25(OH)D3 level <30 nmol/L showed a significantly higher incidence of AD than those with a cord 25(OH)D3 level ≥30 nmol/L (P<0.05). The receiver operating characteristic (ROC) analysis showed that the area under the ROC curve of cord 25(OH)D3 in predicting AD was 0.648 (standard error: 0.075; 95%CI: 0.502-0.795). Its sensitivity, specificity, positive predictive value, and negative predictive value were 52.2%, 79.5%, 57.1%, and 76.1%, respectively. Logistic regression analysis showed that low cord 25(OH)D3 level, preference for seafood during pregnancy, atopic family history, and mixed feeding were risk factors for infantile AD (P<0.05). CONCLUSIONS Cord 25(OH)D3 level is inversely associated with the risk of infantile AD, but it has a low diagnostic value for this disease.

Abstract
BACKGROUND AND OBJECTIVE Vitamin D supplementation in preterm infants has been recommended by American Academy of Pediatrics (AAP); however, its efficacy and safety has not been well studied. To study 25-hydroxy vitamin D (25OHD) levels as a marker of vitamin D status of very low birth weight infants while on vitamin D supplementation during neonatal intensive care unit hospitalization. METHODS Retrospective study of preterm infants with birth weight <1500 g admitted to our unit from January 2013 to December 2015 who were on oral vitamin D3 400 IU supplementation. Serum 25OHD level were checked at 4, 8, and 12 weeks of age or before discharge and the levels were stratified as deficient <20 ng/mL, insufficient 20 to 29 ng/mL, normal 30 to 60 ng/mL, high 61 to 100 ng/mL and very high >100 ng/mL. RESULTS A total of 301 infants were enrolled, 186 very low birth weight (VLBW; 1000-1499 g) infants and 115 extremely low birth weight (ELBW; <1000 g) infants. Approximately 80% of both VLBWs and ELBWs had deficient or insufficient 25OHD levels at 4 weeks of age. On oral vitamin D supplementation, VLBW infants increased their 25OHD levels significantly by 8 and 12 weeks of age, whereas ELBW infants lagged behind at 8 weeks and increased their 25OHD levels by 12 weeks of age. CONCLUSIONS Eighty percent of ELBW and VLBW infants have either deficient or insufficient vitamin D status at 4 weeks of age. Vitamin D supplementation helps in improving the vitamin D levels, VLBW infants significantly more than ELBW infants. AAP recommendation appears to be safe; however, if using higher supplement dosing, 25OHD level should be monitored to avoid high and very high vitamin D levels.

Abstract
OBJECTIVE To investigate the relationship between serum 25-hydroxyvitamin D [25(OH)D] levels at birth and respiratory distress syndrome (RDS) in preterm infants. METHODS This retrospective study recruited preterm infants with gestational age of below 34 weeks who were born between January 2014 and December 2016. These preterm infants were divided into two groups: RDS (n=72) and control (n=40). Clinical data of the two groups were collected, including gestational age, birth weight, gender, delivery mode, Apgar scores at 1 minute and 5 minutes, incidence of maternal gestational diabetes mellitus, and use of prenatal steroid hormone. Peripheral blood samples were collected and 25(OH)D levels were measured by chemiluminescence immunoassay. The association between serum 25(OH)D levels at birth and RDS was analyzed by multivariate logistic regression. RESULTS Apgar scores at 1 minute and 5 minutes and serum 25(OH)D levels in the RDS group were significantly lower than those in the control group (P<0.05), while the rates of neonatal asphyxia and vitamin D deficiency were significantly higher than those in the control group (P<0.05). Multivariate logistic regression analysis showed that neonatal asphyxia (OR=2.633, 95%CI: 1.139-6.085) and vitamin D deficiency (OR=4.064, 95%CI: 1.625-10.165) were risk factors for RDS in preterm infants. CONCLUSIONS Vitamin D deficiency might be associated with increased risk of RDS in preterm infants. Reasonable vitamin D supplementation during pregnancy might reduce the incidence of RDS in preterm infants.

Abstract
OBJECTIVE Vitamin D deficiency (VDD) is common among infants, especially in preterm babies. There are some controversies over its use on body development, immune function and incidence of bronchopulmonary dysplasia (BPD). METHODS We systematically reviewed PubMed, Embase, and Cochrane databases for studies in English, and in Wanfang, VIP, and Cnki databases for Chinese studies (databases were last launched on 1 August 2016). RESULTS Twelve original random controlled studies (seven in English and five in Chinese) were included (1). There are no differences between high-dose (800-1000 IU/d) and low-dose (400 IU/d) groups on calcium, phosphorus, and 25(OH)D concentrations (p > .05). However, length gain and head circumference gain are significantly increased in the high-dose group (p < .05) (2). IL-2, Ig-A, and Ig-G levels are significant increased in the vitamin D supplementation group compared with the control group (p < .05) (3). With respect to BPD, there is no significant difference between the vitamin D supplementation group and the control group (p > .05). CONCLUSIONS In preterm infants, daily supplementation of vitamin D in doses of 800-1000 IU compared with 400 IU appears to be better not only in development but also in immune function. But clinical trials with a larger sample size are still needed.

Abstract
Background To determine the efficacy and safety of early supplementation with 800 IU of vitamin D in very low birth weight (VLBW) infants. Methods Sixty-six infants with a birth weight less than 1500 g admitted to the Neonatal Intensive Care Unit. Of these, 52 infants were eligible and received 800 IU/day vitamin D from 2 weeks of age. We examined 25-hydroxyvitamin-D (25[OH]D) levels from cord blood at birth and serum at 32 and 36 weeks of postmenstrual age. Results The study infants were divided by cord-blood levels of 25(OH)D at birth into 25(OH)D concentrations < 10 ng/mL (n = 20) or ≥ 10 ng/mL (n = 29). Vitamin D intake of 800 IU/day safely achieved an 88% probability of vitamin D sufficiency at 36 weeks postmenstrual age in VLBW infants with cord-blood levels of 25(OH)D ≥ 10 ng/mL, and 65% probability of vitamin D sufficiency was observed in infants with 25 OHD concentrations < 10 ng/mL at birth. Conclusion Considering the efficacy and safety of vitamin D supplementation in this study, vitamin D intake of 800 IU/day may enhance vitamin D status during early hospitalization in VLBW infants with 25 OHD concentrations < 10 ng/mL at birth. The clinical significance of optimal vitamin D intake in VLBW infants needs to be studied in larger controlled studies.
