Analysis of tacrolimus blood concentration and influencing factors in the early postoperative period of lung transplantation patients

OBJECTIVE To explore the clinical characteristics and influencing factors of blood concentration of tacrolimus(Tac)and provide rationales for individualized treatment in early postoperative lung transplant recipients.METHODS From January 2019 to September 2020,medical records were reviewed for 69 lung transplant patients undergoing lung transplantation.And the correlation of blood concentration of Tac with gender,age,clinical indicators and azole antifungal agents within 30 days after transplantation was analyzed. RESULTS Within 30 days post-operation,tacrolimus concentration fluctuated widely and the frequency of reaching the target concentration only accounted for 29.7% of the total monitoring sessions.Age,hematocrit,total bilirubin and combined use of voriconazole & posaconazole were significantly correlated with standardized plasma concentration of Tac.Combined use of voriconazole and posaconazole lowered the mean dose of Tac by 52.8% and 32.5% respectively. CONCLUSION Multiple factors affects the concentration of Tac in early stage of lung transplantation.Under close monitoring,dose should be adjusted timely according to the changes of age,clinical parameters and combined azole antifungal agents.
