Case Cluster of RT-PCR COVID-19 Positive Patients with an Unexpected Benign Clinical Course With Vitamin D, Melatonin, Vitamin C, and Viscum Album

Background: The SARS-COV-2 global pandemic has been noted to have a differential effect on those exposed depending on risk factors such as age, diabetes, cardiovascular disease and cancer. 
 
Case presentation: We report a case series of 12 confirmed positive patients and 12 presumptive positive patients all of whom had either an entirely asymptomatic or relatively mild clinical course. 2 patients had active cancer, 3 patients were cancer survivors, 1 patient without cancer was 74 years old. All patients were treated early in their disease course with vitamin D loading (50,000iu daily for 3 days), 60 to 240mg melatonin, and 2000mg oral vitamin C. The 6 high risk patients and one 59 year old patient were treated with at least 2 intravenous doses of vitamin C. The 2 patients with active cancer received 75 grams of vitamin C (one daily, the other every other day). All of the high risk patients had a nearly asymptomatic clinical course and were tested after 10 days and all had a RT PCR for COVID-19 that was negative. The 17 remaining patients also had a relatively benign course though 4 patients (2 in their 20s, 2 in their 50s) received this treatment course later in the course of their illness, these were notably the only patients who had more than a mild sore throat or low grade fever. 
 
Conclusion: We report these unexpectedly positive clinical outcomes of COVID-19 patients including patients with different risk factors, under supplemental vitamin C and D and melatonin. These supplements have a favorable safety profile and are already being suggested as potentially disease altering therapies in the ongoing COVID-19 pandemic.
