Abstract

Introduction: Quality of sleep is among the factors that affect the improvement of life quality. The previous studies showed that 50%-80% of hemodialysis patients experience sleeping disturbances. Additionally, dialysis patients commonly experience vitamin D deficiency.

Objectives: We aimed to determine the impact of vitamin D deficiency therapy on sleep quality of hemodialysis patients.

Patients and Methods: Thirty hemodialysis patients with 25-hydroxy vitamin D deficiency and Pittsburgh Sleep Quality Index (PSQI) ≥5 were enrolled in this clinical trial. Patients were treated with 50000-unit vitamin D per week for 12 weeks. After treatment, the PSQI score was recalculated for each patient.

Results: Nineteen out of 30 patients (63.3%) were men and 11(36.7%) were women, with a mean age of 56.7 ± 14.3 years. The mean of vitamin D level was 18.61 ± 6.32 ng/mL before treatment and 41.14 ± 9.62 ng/mL after the treatment. The mean of PSQI score at the start of study was 9.97 and after treatment with vitamin D3, it was 9.47 (P > 0.05).

Conclusion: Treatment of vitamin D deficiency did not have any effect on the sleep quality according to the PSQI score in hemodialysis patients.

Trial registration: This randomized controlled trial was registered in the Iranian Registry of Clinical Trials (identifier: IRCT20200223046593N1; https://en.irct.ir/trial/46126, ethical code; IR.SBMU.RETECH.REC.1397.1277).


Implication for health policy/practice/research/medical education:

In a study on 30 hemodialysis patients with vitamin D deficiency and poor sleep quality, we found that the treatment of vitamin D deficiency has no effect on sleep quality according to Pittsburgh Sleep Quality Index (PSQI).
