Abstract
Undernutrition remains a global struggle and is associated with almost 45% of deaths in children younger than 5 years. Despite advances in management of severe wasting (though less so for nutritional edema), full and sustained recovery remains elusive. Children with severe wasting and/or nutritional edema (also commonly referred to as severe acute malnutrition and part of the umbrella term "severe malnutrition") continue to have a high mortality rate. This suggests a likely multifactorial etiology that may include micronutrient deficiency. Micronutrients are currently provided in therapeutic foods at levels based on expert opinion, with few supportive studies of high quality having been conducted. This narrative review looks at the knowledge base on micronutrient deficiencies in children aged 6-59 months who have severe wasting and/or nutritional edema, in addition to highlighting areas where further research is warranted (See "Future Directions" section).

A study of oxidative stress biomarkers and effect of oral antioxidant supplementation in severe acute malnutrition. J Clin Diagn Res 2013; 7:2146-8. [PMID: 24298460 DOI: 10.7860/jcdr/2013/6019.3454] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2013] [Accepted: 07/17/2013] [Indexed: 11/24/2022]
Abstract
BACKGROUND Malnutrition represents one of the most severe health problems in India. Free radicals play an important role in immunological response, which induces the oxidative surplus in severe acute malnutrition. Severe dietary deficiency of nutrients leads to increased oxidative stress in cellular compartments. AIM The goal of this study was to inspect impact of oxidative stress in the form of serum malondialdehyde as product of lipid peroxidation, vitamin E, zinc and erythrocyte superoxide dismutase in patients with severe acute malnutrition. MATERIAL AND METHODS Sixty severe acute malnutrition patients were studied before and after supplementation of antioxidants for one month, and their status were compared with those of 60 age and sex matched healthy controls. The level of serum MDA was analyzed by the Kei Satoh method, serum vitamin E concentration was measured by Baker and Frank Method, serum zinc was measured by using Atomic Absorption Spectrophotometer (AAS) and erythrocyte superoxide dismutase was measured by Kajari Das Method. RESULTS Significantly increased levels of serum malondialdehyde (p<0.001) were found in the patients as compared to those in controls, and significant depletions were found in the levels of serum vitamin E, zinc and erythrocyte superoxide dismutase in patients with severe acute malnutrition as compared to those in controls. After supplementation of antioxidants for one month, the levels of malondialdehyde were found to be decreased significantly (p<0.001) and zinc and erythrocyte superoxide dismutase capacity levels were increased significantly (p<0.05). Also, there was a non-significant (p>0.05) increase in vitamin E levels as compared to those before supplementation results. CONCLUSION Harsh deficiency of various nutrients in severe acute malnutrition leads to generation of heavy oxidative stress. These effects may be minimized with supplementation of antioxidants.

Abstract
Several members of the vitamin B-complex family are known to participate in the normal metabolism of homocysteine (Hcy). Leaving aside the genetic determinants of hyperhomocysteinemia (HHC), the deficiencies of these vitamins can also result in HHC. The situation of sustained and long standing HHC is likely to be prevalent in population groups with low/average socio-economic status, geriatric population and alcohol abusers. If not corrected by supplementation, these population groups certainly are more vulnerable to develop atherosclerosis (AS) and subsequently, cardiovascular disease (CVD). Hyperhomocysteinemia per se and/or HHC-induced oxidative stress result(s) in chronic chemical endothelial injury/dysfunction, smooth muscle proliferation, prothrombotic state and oxidation of low density lipoproteins (LDL) leading to diverse cardiovascular complications. In the first decade of the new millennium, major research efforts would be directed towards understanding the basic mechanism of HHC-induced oxidative stress and the pathophysiology of HHC-induced CVD, culminating in the evolution of hitherto unknown therapeutic strategies such as nutriceuticals and oxidant-antidotes.
