Abstract
Background: Kidney transplant recipients experience heightened systemic inflammation, and biomarkers such as interleukin-6 (IL-6), C-reactive protein (CRP), and high-sensitivity CRP (hsCRP) have been proposed as prognostic indicators.
Objective: This meta-analysis evaluates the associations between IL-6, CRP, and hsCRP levels and all-cause mortality, cardiovascular events, and graft dysfunction in kidney transplant recipients.
Methods: A comprehensive search of PubMed, Web of Science, Scopus, Ovid MEDLINE, and the Cochrane Library until October 11, 2024, identified eligible studies reporting associations between IL-6, CRP, or hsCRP and clinical outcomes in adult kidney transplant recipients.
Results: The systematic review included 40 studies, with 18 meeting criteria for meta-analysis. Elevated IL-6 was associated with a higher risk of graft dysfunction (HR 1.53, 95 % CI 1.28-1.83; I2 = 0 %) and all-cause mortality (HR 1.66, 95 % CI 1.05-2.61; I2 = 97.2 %), but not cardiovascular events. CRP was associated with all-cause mortality (HR 2.07, 95 % CI 1.59-2.70; I2 = 0 %) and cardiovascular events (HR 6.89, 95 % CI 2.52-18.85; I2 = 0 %), but not cardiovascular mortality or graft dysfunction. Elevated hsCRP was associated with all-cause mortality (HR 1.29, 95 % CI 1.15-1.44; I2 = 61 %), but not with cardiovascular events or graft dysfunction.
Conclusions: Among kidney transplant recipients, elevated levels of IL-6, CRP, and hsCRP were significantly associated with increased all-cause mortality, though the association of IL-6 with all-cause mortality showed substantial heterogeneity and should be interpreted with caution. IL-6 also emerged as a predictor of graft dysfunction, while CRP demonstrated a strong association with cardiovascular events. These findings highlight the potential role of inflammatory biomarkers, particularly IL-6 and CRP, in post-transplant risk stratification; however, further studies are needed to establish causality and clarify their clinical utility.
期刊介绍:
Transplant Immunology will publish up-to-date information on all aspects of the broad field it encompasses. The journal will be directed at (basic) scientists, tissue typers, transplant physicians and surgeons, and research and data on all immunological aspects of organ-, tissue- and (haematopoietic) stem cell transplantation are of potential interest to the readers of Transplant Immunology. Original papers, Review articles and Hypotheses will be considered for publication and submitted manuscripts will be rapidly peer-reviewed and published. They will be judged on the basis of scientific merit, originality, timeliness and quality.
