Oxidative stress in neonatal hyperbilirubinemia.

We investigated the role of bilirubin as an antioxidant in neonatal hyperbilirubinemia (NNH) by measuring malondialdehyde (MDA) levels, a marker of oxidative stress and key antioxidant enzymes viz., superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx) in otherwise healthy 70 term newborns with NNH and 20 control newborns without jaundice. Jaundiced newborns had significantly lower MDA but higher SOD, catalase and GPx levels. Furthermore, plasma bilirubin showed significant negative correlation with MDA but positive correlation with antioxidant enzyme activities. It is concluded that NNH is associated with lower oxidative stress.

Lipid peroxidation and antioxidants in neonatal septicemia.

Free radicals have been implicated in the pathogenesis of neonatal septicemia. The present study was planned to estimate the lipid peroxidation and antioxidant status in neonatal septicemia. The study was done to evaluate the lipid peroxidation and antioxidant status, both enzymatic and non-enzymatic in neonates with septicemia. This prospective study included 44 septicemic babies as cases and a group of 84 matched healthy babies formed the control. Malondialdehyde (MDA), Superoxide dismutase (SOD), Glutathione peroxidase (GTPx), Catalase, Uric acid (UA) and Albumin (Alb) were estimated in the serum and compared between the groups. The statistical analysis was done by using SPSS-10 software. Neonates with septicemia had significantly higher levels of MDA, SOD, GTPx, and Catalase, while the levels of UA and Alb were significantly lower as compared to controls (p<0.001). Significantly elevated levels of MDA (p<0.05) and depressed levels of UA (p<0.001) were found in babies with late onset sepsis. Neonates who ultimately succumbed had significantly elevated levels of MDA, SOD, GTPx and Catalase, whereas levels of UA and Alb were significantly depressed (p<0.001). Neonates with sepsis are handicapped in terms of their defense mechanism against free radicals. The utility of supplementation of antioxidant enzymes in neonates with septicemia needs further evaluation.

Risk factors for mortality from neonatal tetanus: 7 years experience in North Bengal, India.

BACKGROUND: Neonatal tetanus (NNT), a preventable disease, remains an important cause of infant mortality in developing countries such as India. OBJECTIVES: To evaluate the demographic and clinical data of NNT in North Bengal, India and determine the risk factors for mortality. METHODS: Hospital records of all cases of NNT admitted over a 7-year period (1997-2003) were analysed. Demographic data, clinical presentation, progression and outcome were evaluated and comparisons made between the group who survived and those who died. RESULTS: The overall mortality was 66.3%. The group who survived had a significantly greater mean bodyweight on admission, later onset of the disease and were hospitalised early. Risus sardonicus, generalised rigidity, fever, intercurrent infections and respiratory arrest were significantly more common in the fatal group. CONCLUSION: Although over the 7 years improvement was observed in admissions for NNT, maternal literacy and the economic status of families, there is a persisting lack of awareness regarding antenatal care, and deliveries are still conducted unhygienically by untrained persons.
