Insights
Pediatric patients with diarrhea and metabolic acidosis were assessed for thiamine status. Thiamine deficiency was not found in those with normal anion gap, but was observed in some with wide anion gap metabolic acidosis.
Area of Science:
- Pediatric Medicine
- Biochemistry
- Clinical Nutrition
Background:
- Diarrhea and metabolic acidosis are common pediatric conditions.
- Thiamine deficiency can present with various symptoms, including neurological and metabolic disturbances.
- Assessing thiamine status in critically ill children is important for timely intervention.
Purpose of the Study:
- To determine the prevalence of thiamine deficiency in children hospitalized with diarrhea and metabolic acidosis.
- To investigate the relationship between anion gap type and thiamine status in this patient population.
Main Methods:
- A preliminary study involving 14 pediatric patients with diarrhea and metabolic acidosis.
- Patients were categorized into two groups based on anion gap: normal and wide.
- Blood samples were analyzed for thiamine and lactate levels upon admission.
Main Results:
- No thiamine deficiency was detected in the normal anion gap group (n=3).
- In the wide anion gap group (n=11), 18.2% showed evidence of thiamine deficiency.
- Elevated lactate levels were observed in both groups, more frequently in the wide anion gap group.
Conclusions:
- Thiamine deficiency is not prevalent in pediatric patients with diarrhea and normal anion gap metabolic acidosis.
- Thiamine deficiency can occur in children with diarrhea and wide anion gap metabolic acidosis, irrespective of lactic acidosis.
- Further research is warranted to confirm these findings in a larger cohort.
Abstract:
This study is a preliminary determination of thiamine status in children with diarrhea and metabolic acidosis admitted to hospital. Children with diarrhea (N = 14; age 2 m-6 yr) were divided into 2 groups according to anion gap type; group 1 (21.4%) with a normal anion gap (5.5 +/- 5.2 mmol/l) and group 2 (78.6%) with a wide anion gap (21.2 +/- 5.2 mmol/l). Blood was taken on the day of admission to determine thiamine and lactate levels. Sixty-six point seven percent of patients in group 1 had a normal lactate level (1.5 +/- 0.8 mmol/l) and 33.3% had a high lactate level (2.2 mmol/l); none had thiamine deficiency (TPPE < 20%). High lactate (3.5 +/- 1.4 mmol/l) was found in 54.5% of group 2 and thiamine deficiency was observed in 18.2% of this group. In conclusion, no thiamine deficiency was noted in patients with normal anion gap, but thiamine deficiency was not uncommon in patients with a wide anion gap, regardless of lactic acidosis.
