Insights
Malnutrition, particularly underweight, significantly increases the risk of death and neurological issues in children with bacterial meningitis (BM). Early identification and intervention are crucial for improving outcomes in affected children.
Area of Science:
- Pediatrics
- Infectious Diseases
- Nutritional Science
Background:
- Malnutrition is a potential cofactor in poor outcomes of childhood bacterial meningitis (BM) in developing nations.
- This study investigated the impact of malnutrition on BM outcomes in Latin American children.
Purpose of the Study:
- To assess the association between nutritional status and the outcomes of childhood bacterial meningitis.
- To determine if malnutrition, specifically underweight and overweight, influences mortality and neurological sequelae in pediatric BM patients.
Main Methods:
- Weight-for-age z scores were used to categorize nutritional status (normal, underweight, overweight) in 482 children (2 months to 5 years) with BM.
- Uni- and multivariate analyses were employed to examine the relationship between malnutrition and clinical outcomes.
- Key indicators assessed included Glasgow Coma Score, cerebrospinal fluid glucose, capillary filling time, death rate, neurological sequelae, and hearing impairment.
Main Results:
- Of 482 children, 54% were normal weight, 31% underweight, and 15% overweight.
- Underweight children presented with lower Glasgow Coma Scores, reduced cerebrospinal fluid glucose, and slower capillary filling times.
- Underweight status was significantly associated with higher mortality rates and increased neurological sequelae, with odds of death escalating with severity of underweight.
Conclusions:
- Underweight children with bacterial meningitis face a substantially higher probability of death and long-term neurological damage.
- Nutritional status is a critical determinant of bacterial meningitis outcomes in pediatric populations.
- Overweight status was not found to be associated with adverse outcomes in this cohort.
Background:
Malnutrition may be an important cofactor explaining poor outcome of childhood bacterial meningitis (BM) in developing countries. We examined its effect in Latin American children.
Methods:
The weight-for-age z score was determined for 482 children with BM aged 2 months to 5 years. Normal weight (z score from >-1 to <+1), underweight (z score <-1) and overweight (z score >+1) children were compared on admission, in-hospital and at discharge. Using uni- and multivariate analysis, we sought for associations between malnutrition and 3 different outcomes.
Results:
The mean z score was -0.41 +/- 1.54, with a normal distribution. Overall, 260 (54%) patients were of normal weight, 151 (31%) underweight, and 71 (15%) overweight. Compared with others, underweight patients had on admission a lower Glasgow coma score (P = 0.0006) and cerebrospinal fluid glucose concentration (P = 0.03), and a slower capillary filling time (P = 0.02). Their death rate was higher (P = 0.0004) and they survived with more neurological sequelae (P = 0.04), but a similar frequency of hearing impairment (P > 0.05). The odds for death increased 1.98 times by mild (95% confidence interval [CI], 1.03-3.83; P = 0.04), 2.55 times by moderate (95% CI, 1.05-6.17; P = 0.04), and 5.85 times (95% CI, 2.53-13.50; P < 0.0001) by severe underweight. Overweight was not associated with adverse outcomes (P > 0.05).
Conclusions:
Children who are underweight at the time of onset of BM have a substantially increased probability of neurological sequelae and death.
