[Abstract]
Background Thiamine deficiency is commonly reported in patients with diabetes especially during diabetic ketoacidosis (DKA) that could attribute to myocardial dysfunction in those patients. However, there is limited data regarding its relation to myocardial function among those patients. This study aimed to explore the association between myocardial function and serum thiamine levels in children with type 1 diabetes mellitus (DM). Methods This cross-sectional comparative study included 25 patients with DKA. Clinical data assessment, echocardiographic examination and measurement of serum high-sensitive troponin T (hs-cTnT) and thiamine levels were done. We also assessed the association between troponin levels, echocardiographic ventricular systolic and diastolic function and serum thiamine. Results Twenty-four percent of children with DKA had thiamine deficiency. DKA children with thiamine deficiency had significant acidosis and higher serum troponin levels and significant impairment of diastolic function than those without thiamine deficiency. The serum thiamine level had a significant positive correlation with the echocardiographic indices of diastolic function but negative correlation with troponin levels. Conclusions Thiamine deficiency is a common finding during the treatment of children with DKA, and this deficiency may be associated with myocardial dysfunction.
