Article Safety and Efficacy of Colchicine in COVID-19 Treatment: Systematic Review and Meta-Analysis(Elsevier, 2025) Nada, Ahmed Hosney; Ibrahim, Ismail A.; Asar, Nada Khalid; Qenawy, Abdulrahman; Mohammed, Mariam M.; Wagdy, Mohamed; Farouk, Heidi SherifBackground: Colchicine is an anti-inflammatory drug used for the treatment of gout and other autoinflammatory conditions. Several trials reported promising results of the efficacy of colchicine in Covid-19 due to its antiinflammatory properties. However, applying these results to clinical settings remains the subject of ongoing research. Methods: We performed a systematic review and meta-analysis on the efficacy and safety of colchicine in the treatment of Covid-19. PubMed, Cochrane Library, Web of Science, and Scopus were searched for relevant studies. The primary outcomes were 28-day mortality, invasive mechanical ventilation, non-invasive mechanical ventilation, and ICU admissions. The risk ratio was used to compare effectiveness between the two groups. Subgroup analysis was done for C-reactive protein and duration of hospitalization. Results: 17 randomized controlled trials with a total of 25478 patients were included. The overall Risk ratio didn't favor any of the two groups in terms of 28-day mortality (RR =1.03, 95 % CI [0.93:1.15], P = 0.58), noninvasive mechanical ventilation (RR = 0.81, 95 % CI [0.44:1.48], P = 0.49), ICU admission (RR = 0.89, 95 % CI [0.56:1.41], P = 0.62). The overall mean difference (MD) did not show statistical significance between both groups in terms of Creactive protein (CRP) (mg/dl) (MD = -1.21, 95 % CI [-2.42:0.01], P = 0.05), lactate dehydrogenase (LDH) (U/ L) (MD = 50.95, 95 % CI [-92.07: 193.98], Ferritin (ng/ml) (MD = 128.08, 95 % CI [51.97:204.18], P = 0.001), ICU length of stay (MD = -0.09, 95 % CI [-0.34:0.15], P = 0.45) and duration of hospitalization (MD = -0.41, 95 % CI [-1.56:0.73], P = 0.48). Conclusion: In Covid-19 treatment, colchicine didn't result in significant benefits in terms of clinical outcomes. More large-scale randomized clinical trials with standardized dosages and long-term follow-up are needed for further investigation into the colchicine effect.Article Citation - Scopus: 12Protective Effects of Petroselinum Crispum (parsley) Extract Against Methotrexate-Induced Hepatotoxicity(Istanbul University Press, 2021) Ertas, B.; Turan, F.B.; Ozbeyli, D.; Yanardag, R.; Sacan, O.; Sener, G.Objective: By inhibiting the synthesis of thymidine and purine, and thereby DNA synthesis, Methotrexate (MTX), suppresses the proliferation of cancer cells. It is thought that the side-effect mechanism is related to oxidant molecules derived from MTX metabolism. In this study, we examined whether the Petroselinum crispum extracts (PCr; parsley) of which the antioxidant properties have been previously shown, was protective against MTX induced liver damage. Materials and Methods: Sprague Dawley rats (female/male; 200-250 g) were used. MTX was injected intraperitoneally and PCr extract was given orally. A single dose of 20mg/kg MTX was administered to the groups that were to experience hepatotoxicity. Then, a physiological saline (MTX group) or PCr (2 g/kg, MTX + PCr group) treatment was applied for 5 days. The same treatments were applied to the other groups (control group, PCr group) for 5 days after a single dose saline injection. At the end of the study, the biochemical parameters were examined in the blood and liver tissues taken from animals sacrificed by decapitation. Results: MTX caused a significant increase in malondialdehyde and collagen levels and myeloperoxidase and caspase-3 activities, while glutathione levels were found to have decreased. PCr treatment showed protective efficacy by preventing these increases. Conclusion: It appears that the administration of PCr to MTX treated rats prevented the accumulation of lipid peroxides, inflamatory reactions and depletion of antioxidant glutathione, and thus protected liver tissues against oxidative stress. © 2021 European Journal of Biology.
