Xerophthalmia, protein-calorie malnutrition, and infections in children
Insights
Children with xerophthalmia, a vitamin A deficiency eye condition, experienced worse malnutrition and higher rates of urinary tract infections compared to those without eye issues. Mortality rates remained similar across groups, indicating infection control was effective.
Area of Science:
- Nutritional Science
- Ophthalmology
- Pediatrics
Background:
- Severe protein-calorie malnutrition (PCM) is a significant health issue in children.
- Vitamin A deficiency, leading to xerophthalmia, often co-exists with PCM.
- The impact of xerophthalmia on malnutrition severity and complications requires further elucidation.
Purpose of the Study:
- To compare clinical characteristics and outcomes of children with severe PCM and xerophthalmia versus those with severe PCM alone.
- To investigate the association between the severity of xerophthalmia and growth retardation.
- To assess the prevalence of infections in children with and without xerophthalmia.
Main Methods:
- Retrospective comparison of inpatient children with severe PCM.
- Groups included children with and without xerophthalmia.
- Data collected on age, hypoproteinemia, anthropometric measurements, infection rates (including urine cultures), and mortality.
Main Results:
- Xerophthalmic children were older, had more severe hypoproteinemia, and greater anthropometric deficits than non-xerophthalmic counterparts.
- Children with severe eye lesions showed more significant growth retardation.
- All children had high infection rates, but xerophthalmic children had significantly more positive urine cultures.
Conclusions:
- Xerophthalmia is associated with more severe malnutrition and increased risk of urinary tract infections in children with severe PCM.
- Despite increased infection rates, mortality was similar, suggesting effective inpatient management.
- Vitamin A status is a critical factor influencing outcomes in severe pediatric malnutrition.
Abstract:
All children with evidence of xerophthalmia who were admitted to an inpatient facility for treatment of severe protein-calorie malnutrition and its complications were compared to other inpatients with severe PCM but free from signs or symptoms of vitamin A deficiency. Xerophthalmic inpatients were older and had more severe hypoproteinemia than inpatients without eye signs, and were more undernourished by anthropometric criteria than a comparison group matched for age, sex, and type of PCM. Children with more severe eye lesions were more retarded in growth than those with minimal ocular signs. All inpatients had high rates of bacterial infections, regardless of their vitamin status. However, xerophthalmic children had a highly significant increase in the rate of positive urine cultures. Mortality rates were similar in all study groups.
