Abstract
Background/aims: This study aimed to identify the risk factors for chronic kidney disease (CKD) and end-stage renal disease (ESRD) following liver transplantation (LT), with a specific focus on tacrolimus levels and intrapatient variability (IPV).
Methods: Among the 1,076 patients who underwent LT between 2000 and 2018, 952 were included in the analysis. The tacrolimus doses and levels were recorded every 3 months, and the IPV was calculated using the coefficient of variability. The cumulative incidence rates of CKD and ESRD were calculated based on baseline kidney function at the time of LT. The impact of tacrolimus levels and their IPV on the development of CKD and ESRD was evaluated, and the significant risk factors were identified.
Results: Within a median follow-up of 97.3 months, the 5-year cumulative incidence rates of CKD (0.58 vs. 0.24) and ESRD (0.07 vs. 0.01) were significantly higher in the acute kidney injury (AKI) group than in the normal glomerular filtration rate (GFR) group. In the normal GFR group, the tacrolimus levels were identified as a risk factor for CKD, with a level of ≤4.5 ng/mL suggested as optimal for minimizing the risk of CKD. Furthermore, the IPV of tacrolimus levels and doses emerged as a significant risk factor for CKD development in both groups (P<0.05), with tenofovir disoproxil fumarate also being a risk factor in HBV-infected patients. The IPV of tacrolimus levels was also a significant factor in ESRD development (P<0.05).
Conclusions: This study elucidated the optimal tacrolimus through level and highlighted the impact of IPV on the CKD and ESRD development post-LT.
期刊介绍：
Clinical and Molecular Hepatology is an internationally recognized, peer-reviewed, open-access journal published quarterly in English. Its mission is to disseminate cutting-edge knowledge, trends, and insights into hepatobiliary diseases, fostering an inclusive academic platform for robust debate and discussion among clinical practitioners, translational researchers, and basic scientists. With a multidisciplinary approach, the journal strives to enhance public health, particularly in the resource-limited Asia-Pacific region, which faces significant challenges such as high prevalence of B viral infection and hepatocellular carcinoma. Furthermore, Clinical and Molecular Hepatology prioritizes epidemiological studies of hepatobiliary diseases across diverse regions including East Asia, North Asia, Southeast Asia, Central Asia, South Asia, Southwest Asia, Pacific, Africa, Central Europe, Eastern Europe, Central America, and South America.
The journal publishes a wide range of content, including original research papers, meta-analyses, letters to the editor, case reports, reviews, guidelines, editorials, and liver images and pathology, encompassing all facets of hepatology.
