dc.description.abstract | Aim: Clozapine is an atypical antipsychotic (AAP) drug used in treatment-resistant schizophrenia patients. The adverse effects of clozapine on the heart may result in death and require drug discontinuation. Inflammatory mechanisms are thought to be responsible for the negative effect of clozapine on the heart. This suggests that using an agent with anti-inflammatory and antioxidant properties, which may be specific to clozapine-induced heart damage, may prevent possible damage. The aim of our study is to evaluate the effect of taxifolin (3,5,7,3’,4’-pentahydroxy flavanone), an agent with known antioxidant and anti-inflammatory effects, on myocardial damage caused by clozapine with biochemical and histopathological data. Material and method: The rats were divided into three equal groups: healthy control group (HC), clozapine-treated group (CLN), and taxifolin + clozapine-treated group (TCL). To perform this experiment, taxifolin was administered to TCL (n-6) rats at a dose of 50 mg/kg orally by gavage into the stomach. In the HC (n-6) and CLN (n-6) groups, the same volume of distilled water was administered orally as a solvent. One hour after the administration of taxifolin and distilled water, clozapine was administered orally at a dose of 20 mg/kg to the TCL and CLN groups once a day for 28 days. At the end of the period, troponin I (TP I) and creatine kinase MB (CK-MB) levels were measured in the venous blood of each group. Malondialdehyde (MDA), total glutathione (tGSH), TNF-?, NF-[Formula presented]B, and IL-1? levels were measured in samples taken from heart tissues. Additionally, heart tissues were evaluated histopathologically. Results: Troponin I, CK-MB, MDA, TNF-?, NF-[Formula presented]B, and IL-1? levels, myocardial degeneration, myofiber irregularity, and congestion scores were significantly higher and tGSH levels were lower in the clozapine group than in the healthy control and taxifolin + clozapine groups (P < 0.05). Compared with the healthy control group, troponin I, tGSH, and NF-KB levels were similar (P > 0.05), CK-MB, MDA, TNF-?, and IL-1? levels were higher in the taxifolin + clozapine group, while they were significantly lower than the clozapine group (P < 0.05). Histopathologically evaluated myocardial degeneration, myofiber irregularity, and congestion score were significantly lower in the taxifolin + clozapine group than in the clozapine group. In the clozapine group (CLN group), myofibers were found to have irregular patterns and were observed as irregular. In the taxifolin + clozapine group (TLC group), myofibrils generally showed a regular morphology. Conclusion: We found that taxifolin can ameliorate damage to myocardial tissue by regulating oxidant-antioxidant and proinflammatory cytokine levels. The data of our study suggest that taxifolin may be useful in the treatment of clozapine-induced myocardial injury. © 2023 Elsevier Masson SAS | en_US |
