ascorbic-acid and Jaundice--Neonatal

Jaundice is a typical condition in the neonatal period, particularly in the Asian continent. Drowsiness and disruption of breastfeeding, behavioral and neurological disorders, hearing loss and mental retardation are the results of impairment in controlling it. The increase in oxidant substances can stimulate the heme oxygenase enzyme and increase the conversion of heme to bilirubin. In some studies, vitamin C levels in the blood of infants with hyperbilirubinemia were lower than in healthy infants.. In this double-blind clinical trial study, 144 healthy pregnant women aged 20-40 years who were in 34th weeks of gestation were randomly divided into intervention, and control groups and until the end of pregnancy, they took a 500 mg tablet of vitamin C or placebo (Preparation of starch) daily. Demographic information, dietary intake, and physical activity level of the participants were also evaluated. The total blood bilirubin level was measured on the fifth day after birth using a sample of the neonatal heel. Statistical analysis was performed using SPSS software version 22. In this study P-value < 0. 05 was considered significant.. Of the 144 participants, 128 of them completed the intervention. There was no significant difference between the two groups at the level of vitamin C intake through diet, and anthropometric indices, but the total bilirubin level in the neonates of the two groups was statistically different (P = 0.02).. Vitamin C supplementation in the last month of pregnancy had a significant effect on neonatal bilirubin level and decreased it significantly.

Haemoglobin variants and preeclampsia (PE) are associated with adverse fatal events of which oxidative stress may be an underlying factor. Oxidative stress (OS) among preeclamptic women with haemoglobin variants has been well established. It is, however, unclear whether haemoglobin variants induce OS to aggravate the risk of adverse foeto-maternal outcomes in pregnant women with preeclampsia. We measured the levels of OS biomarkers and determined the association between haemoglobin variants, and adverse foeto-maternal outcomes among pregnant women with PE.. This multi-centre prospective study recruited 150 PE women from three major health facilities in both Bono and Bono east regions of Ghana from April to December 2019. Haemoglobin variants; HbAS, HbSS, HbSC, HbCC, and HbAC were determined by haemoglobin electrophoresis. OS biomarkers such as malondialdehyde (MDA), catalase (CAT), vitamin C, and uric acid (UA) along with haematological and biochemical parameters were estimated using standard protocol. Adverse pregnancy complications (APCs) such as post-partum haemorrhage (PPH), HELLP (Haemolysis, Elevated liver enzymes, Low platelet count) syndrome, preterm delivery, neonatal intensive care unit (NICU) admission, and neonatal jaundice were recorded.. Of the 150 pregnant women with preeclampsia, the distribution of haemoglobin AA, AS, AC, CC, SS and SC phenotypes were 66.0%, 13.3%, 12.7%, 3.3%, 3.3% and 1.3%, respectively. The most prevalent foeto-maternal outcomes among PE women were NICU admission (32.0%) followed by PPH (24.0%), preterm delivery (21.3%), HELLP syndrome (18.7%), and neonatal jaundice (18.0%). Except for vitamin C level which was significantly higher in patients with at least a copy of Haemoglobin S variant than those with at least a copy of Haemoglobin C variant (5.52 vs 4.55; p = 0.014), levels of MDA, CAT, and UA were not statistically significantly different across the various haemoglobin variants. Multivariate logistic regression model showed that participants with HbAS, HbAC, having at least a copy of S or C and participants with HbCC, SC, SS had significantly higher odds of neonatal jaundice, NICU admission, PPH and HELLP syndrome compared to participants with HbAA.. Reduced levels of vitamin C are common among preeclamptics with at least one copy of the HbC variant. Haemoglobin variants in preeclampsia contribute to adverse foeto-maternal outcomes with Haemoglobin S variants being the most influencing factor for PPH, HELLP, preterm labour, NICU admission, and neonatal jaundice.

Newborns, particularly preterm infants, have limited antioxidant protective capacity. The organism's defence system against reactive oxygen species including vitamins A, E and C, trace element selenium (Se) and enzymes, such as catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) are essential components of the antioxidant system against the oxidative injury to the cellular membranes of erythrocytes. In this study, our aim was to compare the oxidant nitric oxide (total plasma nitrite level as an indicator of nitric oxide (NO)), antioxidant vitamins and selenium and erythrocyte antioxidant enzymes in premature babies with hyperbilirubinaemia with healthy preterms.. Twenty preterm infants with newborn jaundice were included in the study group, while 15 preterm infants without jaundice were enrolled in the control group. We evaluated the mean plasma levels of, respectively, the total nitrite as an indicator of NO, bilirubin, vitamins A, E, C and selenium, and the activity of erythrocyte antioxidant enzymes such as CAT, SOD and GSH-Px of preterm infants with idiopathic hyperbilirubinaemia and compared to those of the control group.. The mean plasma total nitrite and total serum bilirubin levels and blood reticulocyte counts of the study group were found to be significantly higher than those of the control group (P < 0.001, P < 0.001 and P < 0.05, respectively). Furthermore, the activity of erythrocyte antioxidant enzymes (all P < 0.001) and the mean plasma levels of the antioxidant vitamins A, E, and C (P < 0.05, P < 0.05 and P < 0.001, respectively) and selenium (P < 0.001) of the study group were all found to be significantly lower than those of the control group.. We hypothesize that low antioxidants in pretem babies may predispose them to increased oxidative stress, and cause hyperbilirubinaemia.

The cause of the Premature Infant Anemia (PIA) is mainly an insufficient erythropoiesis, a shorter mean-life of the red cells and in increased hemolysis. On these basis of prophylaxis has been attempted by treating newborns with folic acid, alpha-tocopherol and vitamins B1, B2, B6 and C. 208 premature babies have been treated (birth weight higher than 1750 nr. 171; birth weight less than 1750 nr. 37). Several parameters have been evaluated: weight gain, erythrocyte and reticulocyte count, jaundice occurrence and number of transfusions needed. The results on the blood parameters was good for the small babies group and sufficient for the others. Differences have been observed between the two groups for the occurrence of jaundice and transfusions.
