Vitamin D (Cholecalciferol) With Low Dose Vitamin C As A Safe And Effective Therapeutic Modality In An Adult With Covid-19 Pneumonia

This is a case of an elderly female presenting with fever, cough and shortness of breath. On presentation, she had tachypnea and an oxygen requirement of 2 liters through nasal prongs. Her investigations were suggestive of COVID-19 pneumonia with bilateral ground-glass appearance on chest X-ray and a positive nasopharyngeal PCR swab. She had low vitamin D levels on presentation and was given 200,000 units of cholecalciferol, once daily for 3 days with Vitamin C, 500 mg per oral once daily for 7 days. Her symptoms got progressively better and her oxygen requirement diminished on next day. On day 3, her symptoms completely resolved, and her chest X-ray improved. In patients with COVID-19 pneumonia, who are vitamin D deficient, administration of large doses of cholecalciferol for few days can be a safe option to treat mild to moderate COVID-19 pneumonia.
