Insights
Hypothermia, hypoglycaemia, altered consciousness, and bronchopneumonia significantly increase mortality risk in severely-malnourished children with shigellosis. Early diagnosis and prompt treatment of these conditions are crucial for reducing Shigella-related deaths.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Shigellosis is a major cause of childhood mortality, particularly in severely malnourished populations.
- Identifying risk factors for death in these vulnerable children is critical for effective intervention.
Purpose of the Study:
- To determine the risk factors associated with mortality in severely-malnourished Bangladeshi children diagnosed with shigellosis.
- To inform clinical management strategies aimed at reducing Shigella-related deaths in this high-risk group.
Main Methods:
- A case-control study comparing 100 deceased severely-malnourished children with shigellosis to 100 survivors.
- Data collected included clinical signs, laboratory values, and demographic information from hospitalized children aged <4 years.
Main Results:
- Bronchopneumonia, altered consciousness, hypothermia, and hypoglycaemia were identified as significant independent risk factors for mortality.
- Children presenting with these conditions had a substantially higher odds ratio for death.
Conclusions:
- Severely-malnourished children with shigellosis exhibiting hypothermia, hypoglycaemia, altered consciousness, or bronchopneumonia are at a significantly elevated risk of death.
- Prompt diagnosis and assertive management of these critical conditions are essential to reduce mortality in this population.
Abstract:
To determine the risk factors for death of severely-malnourished Bangladeshi children with shigellosis, a case-control study was conducted at the Clinical Research and Service Centre of ICDDR,B: Centre for Health and Population Research in Dhaka, Bangladesh. One hundred severely-malnourished children (weight-for-age <60% of median of the National Center for Health Statistics), with a positive stool culture for Shigella dysenteriae type 1 or S. flexneri, who died during hospitalization, were compared with another 100 similar children (weight-for-age <60% and with S. dysenteriae type 1 or S. flexneri-associated infection) discharged alive. Children aged less than four years were admitted during December 1993-January 1999. The median age of the cases who died or recovered was 9 months and 12 months respectively. Bronchopneumonia, abdominal distension, absent or sluggish bowel sound, clinical anaemia, altered consciousness, hypothermia, clinical sepsis, low or imperceptible pulse, dehydration, hypoglycaemia, high creatinine, and hyperkalaemia were all significantly more frequent in cases than in controls. In multivariate regression analysis, altered consciousness (odds ratio [OR]=2.6, 95% confidence interval [CI] 1.0-6.8), hypoglycaemia (blood glucose <3 mmol/L (OR=7.8, 95% CI 2.9-19.6), hypothermia (temperature <36 degrees C) (OR=5.7, 95% CI 1.5-22.1), and bronchopneumonia (OR=2.5, 95% CI 1.1-5.5) were identified as significant risk factors for mortality. Severely-malnourished children with shigellosis having hypoglycaemia, hypothermia, altered consciousness and/or bronchopneumonia were at high risk of death. Based on the findings, the study recommends that early diagnosis of shigellosis in severely-malnourished children and assertive therapy for proper management to prevent development of hypothermia, hypoglycaemia, bronchopneumonia, or altered consciousness and its immediate treatment are likely to reduce Shigella-related mortality in severely-malnourished children.
