Treatment of Thiamine Deficiency in End-Stage Renal Disease (ESRD)
Prevalence and Risk Factors
- Dialysis therapy increases losses of water-soluble vitamins, including thiamine, in patients with End-Stage Renal Disease (ESRD) 1, 2
- Poor nutritional status, common in patients with declining renal function, is a risk factor for thiamine deficiency in ESRD 3
Pathophysiology of Thiamine Deficiency in ESRD
- Decreased dietary intake due to uremic anorexia contributes to thiamine deficiency in ESRD patients 3
- Increased metabolic demands in the uremic state affect thiamine levels in ESRD patients 2
Diagnosis and Treatment
- The National Kidney Foundation recommends monitoring thiamine status in ESRD patients regularly, especially those on dialysis therapy 1
- High-dose thiamine supplementation (100-300 mg/day) is recommended for acute thiamine deficiency in ESRD patients, with ongoing losses through dialysis requiring higher maintenance doses 2, 1, 4
Special Considerations for Dialysis Patients
- Patients on continuous renal replacement therapy (CKRT) require higher doses of thiamine supplementation due to increased losses 1
- Administering 2-3 vials of standard multivitamin preparations daily can help achieve adequate thiamine dosing for patients on CKRT 4
Monitoring and Follow-up
- Regular monitoring of thiamine levels is recommended, particularly in patients with ongoing risk factors, to adjust dosing 1
- Thiamine supplementation is generally well-tolerated even at high doses, but rare adverse effects should be monitored 4
