It was hypothesized that consumption of hen egg white and bovine colostrum would reduce risk of progression to severe disease in patients with mild/moderate coronavirus disease of 2019 (COVID-19). In this double-blind randomized control study, COVID-19 positive individuals at increased risk of severe disease and within 5 days of symptom onset were randomly assigned to consume hen egg white and bovine colostrum (n = 77) or placebo (n = 79) twice daily for 5 days. During the 6-week follow-up, information on symptoms and Karnofsky status were collected telephonically on days 2, 4, 7, 14 and 28 post-enrollment, as well as at a clinic visit at 11-13 days post-symptom onset, during which viral clearance was assessed via combined nasal and oropharyngeal swabs. Post-COVID-19 symptoms were assessed telephonically at day 42. Only 1 participant (active arm) progressed to severe disease. There were significantly fewer protocol-defined severe-type symptoms in the active arm at day 4 (p = 0.046) and day 11-13 (p = 0.007). The individual symptoms that were significantly reduced in the active arm were chest pain (day 4, p = 0.038), fever/chills (day 7, p = 0.014), joint pain/malaise (day 11-13, p = 0.009), and sore throat (day 11-13, p = 0.038). No significant differences in Karnofsky score, viral clearance or post-COVID-19 sequelae were observed. The intervention reduced symptoms in individuals with mild/moderate COVID-19. The trial was registered at sanctr.samrc.ac.za (DOH-27-062021-9191). 2. The trial protocol and protocol appendices.
