Growth and immune function in Aboriginal children during recovery from malnutrition and infection
Insights
Malnourished Aboriginal children experienced slow weight gain during recovery from infection and malnutrition. Persistent immune stimulation suggests underlying issues contributing to high reinfection rates.
Area of Science:
- Pediatrics
- Immunology
- Nutritional Science
Background:
- Malnutrition and infection are significant health challenges in Aboriginal children.
- Understanding the clinical, nutritional, and immunological interplay is crucial for effective treatment.
Purpose of the Study:
- To investigate the clinical, nutritional, and immunological changes in Aboriginal children with malnutrition and infection.
- To compare recovery patterns between malnourished and adequately nourished children.
Main Methods:
- Studied 30 Aboriginal children with malnutrition and infection, and 11 controls with acute infection.
- Monitored clinical progress, nutritional status (weight velocity), and immunological markers (leukocytosis, lymphoid cells, ESR, immunoglobulins).
Main Results:
- Malnourished children had a slower weight velocity (3-7 g/kg/day) during nutritional rehabilitation.
- All children exhibited persistent immunological stimulation, including leukocytosis and hyperimmunoglobulinaemia.
- Short-term antibiotic therapy and nutritional rehabilitation did not significantly alter immunological findings.
Conclusions:
- Moderate protein-calorie malnutrition of the marasmic type was prevalent.
- Persistent immune stimulation may indicate an underlying defect.
- This underlying defect could contribute to high rates of reinfection and readmission in these children.
Abstract:
The clinical, nutritional progress and immunological changes of 30 Aboriginal children admitted to the Alice Springs Hospital with malnutrition and infection, and 11 adequately nourished children admitted with acute infection were studied. The initial toxic phase of infection lasted from six to 21 days during which the mean weight velocity of malnourished children averaged 8-8 g/kg/day. The subsequent period of nutritional rehabilitation was accompanied by a slower weight velocity of 3-7 g/kg/day up to a body weight at discharge of approximately 80% standard weight for age. The principal clinical form of malnutrition was moderate protein calorie malnutrition of marasmic type. All children showed laboratory evidence of persistent immunological stimulation with leukocytosis, elevated numbers of T and B lymphoid cells, raised erythrocyte sedimentation rates and hyperimmunoglobulinaemia. These findings were not significantly changed by short-term antibiotic therapy and nutritional rehabilitation and may indicate an underlying defect resulting in the high rate of reinfection and readmission of these children.
