[Stool electrolyte concentration in acute infantile diarrhea in France]
Insights
In children with acute diarrhea, stool electrolyte concentrations of sodium, potassium, and chloride did not significantly vary by infection cause or treatment. These findings support consistent rehydration and nutrition protocols for pediatric diarrhea management.
Area of Science:
- Pediatric Gastroenterology
- Infectious Diseases
- Clinical Chemistry
Context:
- Acute diarrhea is a common illness in infants and young children.
- Electrolyte imbalances can be a serious complication of diarrhea.
- Understanding stool electrolyte content is crucial for managing dehydration.
Purpose:
- To analyze stool sodium, potassium, and chloride content in children with acute diarrhea.
- To determine if electrolyte concentrations vary based on the cause of diarrhea (rotavirus, invasive pathogens, or unknown etiology).
- To assess the impact of treatment protocols (rehydration, realimentation) on stool electrolyte levels.
Summary:
- Electrolyte concentrations (Na+, K+, Cl-) in stool samples from 107 children (1-32 months) with acute diarrhea were measured.
- No significant variations in mean electrolyte concentrations were observed across different etiologies (rotavirus, invasive pathogens, unknown) or according to the duration/severity of diarrhea.
- Electrolyte levels also remained consistent irrespective of the therapeutic protocol, including oral rehydration and nutrition.
Impact:
- Provides baseline data on stool electrolyte concentrations in pediatric acute diarrhea.
- Suggests that etiology and standard rehydration/nutrition protocols do not significantly alter stool electrolyte loss.
- Informs clinical management by highlighting the stability of electrolyte content in diarrheal stools.
Abstract:
Sodium, potassium and chloride stool content was studied in 107 children aged 1 to 32 months (11 +/- 8 months) presenting with acute diarrhea related to a rotavirus infection (34 cases), to an invasive pathogen (Salmonella or Shigella 14 cases, E. coli 4 cases), or of non-identified etiology (65 cases). The therapeutic protocol was the same in all cases: rehydration for the first 24 hours, progressive realimentation from the second or third day, no drugs being given. An average of 4 stools were analysed for each child (range 2-14), the fecal samples being collected over 2 to 4 consecutive days. Na+ and K+ (n = 366) were assayed by flame photometry and chloride (n = 88) by continuous colorimetry. In the stool samples taken as a whole, without taking into account etiology or day of sampling, the electrolyte concentration (mean +/- SD) was 42 +/- 20 mmol/l for Na+ (range 4-166), 51 +/- 24 mmol/l for K+ (range 5-195), and 24 +/- 11 mmol/l for Cl- (range 4-93). No significant variation of these values was observed according to etiology, duration, severity of the diarrheal syndrome, oral rehydration or nutrition.
