Abstract

Background and Objective: The present study aimed to investigate the effects of propolis and melatonin supplementation on inflammation, clinical outcomes, and oxidative stress markers in patients with primary pneumosepsis. Materials and Methods: This pilot randomized controlled trial was conducted on 55 patients with primary pneumosepsis who were randomly assigned to the intervention and control groups. In the three intervention groups, the patients received propolis alone (1,000 mg/day), propolis (1,000 mg/day) plus melatonin (20 mg/day), and melatonin alone (20 mg/day). The control group received placebo. The inflammatory and oxidative stress markers as well as clinical outcomes were evaluated before and after the intervention, and the 28-day survival rate was also recorded. Results: After the intervention, the combination of propolis and melatonin significantly reduced interleukin-6 (-55.282 pg/mL) and C-reactive protein (-21.656 mg/L) levels, while increasing gavage intake (326.680 mL/day) and improving some clinical outcomes (APACHE II, SOFA, and NUTRIC scores) compared to the control group. However, no significant difference was observed between the groups in terms of oxidative stress and hematological indices. In addition, there was no significant difference in the 28-day survival rate between the groups (p = 0.07). Conclusion: Supplementation with propolis and melatonin may improve clinical outcomes by reducing inflammation. Further investigations are required to confirm these findings. © 2022 S. Karger AG.
