| Background: The present study aimed to assess the therapeutic effects of boron citrate and oleoylethanolamide
supplementation in patients with COVID-19.
Methods: Forty adult patients with a diagnosis of COVID-19 were recruited in the present study. Patients were
randomized in a 1:1:1:1 allocation ratio to 1of 4 treatment groups: (A) 5 mg of boron citrate twice a day, (B) 200
mg of oleoylethanolamide twice a day, (C) both therapies, or (D) routine treatments without any study medications.
At pre-and post-intervention phase, some clinical and biochemical parameters were assessed.
Results: Supplementation with boron citrate alone or in combination with oleoylethanolamide significantly
improved O2 saturation and respiratory rate (p < 0.01). At the end of the study, significant increases in white
blood cell and lymphocyte count were observed in the boron citrate and combined groups (p < 0.001). Boron
citrate supplementation led to a significant decrease in serum lactate dehydrogenase (p = 0.026) and erythrocyte
sedimentation rate (p = 0.014), compared with other groups. Furthermore, boron citrate in combination with
oleoylethanolamide resulted in a significant reduction in the high-sensitivity C-reactive protein and interleukin-
1β concentrations (p = 0.031 and p = 0.027, respectively). No significant differences were found among four
groups post-intervention, in terms of hemoglobin concentrations, platelet count, and serum interleukin-6 levels.
At the end of the study, common symptoms of COVID-19 including cough, fatigue, shortness of breath, and
myalgia significantly improved in the supplemented groups, compared to the placebo (p < 0.05).
Conclusion: Supplementation with boron citrate alone or in combination with oleoylethanolamide could improve
some clinical and biochemical parameters in COVID-19 patients. |
