Thiamine in Pediatric Sepsis: A Motivating Study

Thiamine status during treatment of diabetic ketoacidosis in children - tertiary care centre experience

OBJECTIVES

There is a lack of information regarding thiamine status in children with diabetic ketoacidosis (DKA). This study was designed to assess the thiamine status upon admission and 24 h after treatment initiation of DKA, whether newly diagnosed children or with established T1DM diagnosis, who presented with DKA.

METHODS

We enrolled 90 children (mean age, 9.8 ± 2.6 years; 58 females and 32 males) with type 1 diabetes mellitus (T1DM), whether newly diagnosed or with an established T1DM diagnosis (from 1 to 5.2 years ago), who presented with DKA. We observed the initial Glasgow Coma Scale (GCS) and recovery time. The whole blood thiamine diphosphate levels were measured upon admission (baseline point) and 24 h after initiation of the DKA treatment (second-time point).

RESULTS

The mean blood thiamine levels at the second-time point (90.11 ± 15.76 nmol/L) significantly decreased compared with their levels at baseline (108.8 ± 17.6 nmol/L) (p<0.001). We compared thiamine levels with the initial GCS, patient's age, and recovery time. Thiamine levels at the second-time point were positively correlated with baseline thiamine levels (r=0.86, p=0.0001) and the initial GCS (r=0.68, p=0.001) but were negatively correlated with patient's age (r=-0.61, p=0.001) and recovery time (r=-0.724, p=0.001). Based on multiple regression analysis, thiamine levels at the second-time point were directly related to the initial GCS and inversely related to the patient's age.

CONCLUSIONS

The current study indicates that blood thiamine diphosphate levels significantly decreased after 24 h of DKA treatment initiation compared to pre-treatment levels. After 24 h of treatment initiation, blood thiamine levels are directly related to the initial GCS and inversely related to the patient's age.
