Abstract:Objective To explore the clinical effect of combined use of Cyclosporine A (CsA) and Diltiazem (DTZ) in patients undergoing clinical kidney transplantation, and to evaluate the effect of DTZ on the blood concentration of CsA in kidney transplant patients. Methods A total of 108 patients who underwent kidney transplantation at the First Affiliated Hospital of University of Science and Technology of China (Anhui Provincial Hospital) from January 2013 to December 2017 were collected, and they were divided into the control group (54 cases) and the study group (54 cases) by random number table method. The patients in the control group only used CsA after the operation, while the study group received both CsA and DTZ after the operation. The data of CsA dosage and blood drug concentration of two groups one to six months after operation, and the liver and kidney toxicity of CsA were analyzed. Results There were no significant differences in CsA blood concentration and interaction between the two groups after renal transplantation (P > 0.05); the difference was statistically significant in time comparison (P < 0.05). Among them, the CsA blood concentration two to six months after oparation of the two groups were lower than one month after operation, and the CsA blood concentration three to six months after operation were lower than two months after operation, and the differences were statistically significant (P < 0.05). The differences between the two groups in the dose and time of CsA administration were statistically significant (P < 0.05); while the interaction comparison, and the difference was not statistically significant (P > 0.05). Among them, two, four and six months after operation were lower than one month after operation, the dose of CsA used in three months after operation was lower than two months after operation, while four and six months after operation were lower than three months after operation, and the differences were statistical significance (P < 0.05). After treatment, the levels of serum creatinine, urea nitrogen and uric acid between the two groups were lower than those before treatment, and the differences were statistically significant (P < 0.05). Conclusion DTZ can significantly increase the blood concentration of CsA and reduce the dosage of CsA, thereby reducing the side effects of CsA and reducing the economic burden of patients.
