ABSTRACT

PurposeToday, coronavirus disease-19 (COVID-19) treatment is an evolving process, and synbiotic administration has been suggested as a new therapeutic strategy. This study aims to investigate the effect of synbiotic supplementation in COVID-19 patients.Design/methodology/approachIn this placebo-controlled trial, 80 patients were randomized to receive oral synbiotic capsule (containing fructooligosaccharide and seven bacterial strains;Lactobacillus (L) casei, L. rhamnosus, Streptococcus thermophilus, Bifidobacterium breve, L. acidophilus, Bifidobacterium longum, L. bulgaricus, each one 109 colony-forming units) or placebo for two months. Inflammatory markers (Interleukin-6 [IL-6], C-reactive protein [CRP], erythrocyte sedimentation rate [ESR]) and white blood cell (WBC) count were evaluated at two timepoints (baseline, two months later). The measured variables were adjusted for confounders and analyzed by SPSS v21.0.FindingsAll 80 enrolled patients completed the study. The study adherence was good (approximately 70%). The mean changes for IL-6 were not significant (Δ = −0.6 ± 10.4 pg/mL vs Δ = +11.2 ± 50.3 pg/mL, p > 0.05). There were no significant improvements for CRP, ESR and WBC.Originality/valueAdministration of synbiotics for two months did not improve inflammatory markers in COVID-19 patients.

ABSTRACT

Background: Angiotensin II receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEinhs) may deteriorate or improve the clinical manifestations in severe acute respiratory syndrome coronavirus 2 infection. A comparative, cross-sectional study was conducted to evaluate the association of ARBs/ACEinhs and hydroxy-3-methyl-glutaryl-CoA reductase inhibitors (HMGRis) with clinical outcomes in coronavirus disease 2019 (COVID-19). Materials and Methods: From April 4 to June 2, 2020, 659 patients were categorized according to whether they were taking ARB, ACEinh, or HMGRi drugs or none of them. Demographic variables, clinical and laboratory tests, chest computed tomography findings, and intensive care unit-related data were analyzed and compared between the groups. Results: The ARB, ACEinh, and HMGRi groups significantly had lower heart rate (P < 0.05). Furthermore, a lower percent of O2 saturation (89.34 ± 7.17% vs. 84.25 ± 7.00%; P = 0.04) was observed in the ACEis group than non-ACEinhs. Mortality rate and the number of intubated patients were lower in patients taking ARBs, ACEinhs, and HMGRis, although these differences failed to reach statistical significance. Conclusion: Our findings present clinical data on the association between ARBs, ACEinhs, and HMGRis and outcomes in hospitalized, hypertensive COVID-19 patients, implying that ARBs/ACEinhs are not associated with the severity or mortality of COVID-19 in such patients.

ABSTRACT

BACKGROUND & AIMS: There are some studies indicating the effects of probiotic-containing foods or supplements on viral diseases. We aimed to conduct a rapid review of probiotics with specific emphasis on their potential for early administration in patients at greater risk of SARS-CoV-2 infection. METHODS: We searched on PubMed, EMBASE, Google Scholar, Science Direct, Scopus and Web of Science up to February 2021 to identify interventional and observational studies documenting the effects of probiotics strains on interleukins, virus titers, and antibody production with a focus on probiotic-containing foods (PROSPERO Registration ID. CRD42020181453) RESULTS: From a total of 163 records, 21 studies were classified into three domains based on the efficacy of probiotics on 1) the level of interleukins (n = 7), 2) virus titers (n = 2), and 3) interferon (IFN) and antibody production (n = 12). The suppuration of pro-inflammatory interleukins and type I INF production seemed to be the main anti-viral effect of probiotics. Nine studies also indicated the beneficial effects of probiotics and fermented foods on viral diseases. CONCLUSION: Based on evidence, some probiotic strains may be useful in viral infections; randomized trials are needed to confirm these findings.
