Summary

The goal of this clinical trial is to evaluate the effectiveness of vitamin D supplementation in treating neuropsychiatric symptoms and improving antioxidant levels in individuals diagnosed with post-COVID-19 condition, a state known as long-COVID. These individuals are primarily adults who have recovered from severe COVID-19 and exhibit persistent symptoms. The main questions it aims to answer are:

Does vitamin D (cholecalciferol) supplementation decrease levels of anxiety and depression in patients with post-COVID-19 condition? Does vitamin D (cholecalciferol) supplementation increase glutathione peroxidase (GPx) activity in these patients? Researchers will compare the effects of daily versus bolus doses of vitamin D (cholecalciferol) to see if one method is more effective than the other in achieving sufficient vitamin D levels and improving clinical outcomes.

Participants will:

Be randomly assigned to receive either a daily dose or a bolus dose of vitamin D over an 8-week period.

Undergo blood tests to measure biochemical markers such as interleukin-6 (IL-6) and GPx before and two months after starting supplementation.

Have their lung function tested using spirometry and diffusing capacity for carbon monoxide.

Complete the Hospital Anxiety and Depression Scale to assess changes in anxiety and depression levels.

Interventions

DRUG

vitamin D (cholecalciferol) supplementation

This clinical pilot study administered and compared daily and bolus dosing regi-mens of vitamin D to achieve and maintain optimal serum levels of 25(OH)D in post-COVID patients. The daily dose group received constant and gradual supplementation of cholecalciferol, intended to achieve more stable 25(OH)D levels without peaks. Conversely, the bolus group received a weekly dose that could lead to rapid increases followed by gradual declines in 25(OH)D levels. The Daily dose of cholecalciferol was calculated using the following formula: Daily dose of cholecalciferol = \[Weight (kg) × desired increase in 25(OH)D (ng/ml) × 2.5\] - 10 .
