Caught in the Crossfire: Unmasking the Silent Renal Threats of Tyrosine Kinase Inhibitors in Chronic Myeloid Leukemia.

backgroundRenal adverse drug reactions (ADRs) associated with tyrosine kinase inhibitors (TKIs) in the treatment of chronic myeloid leukemia (CML) are relatively rare, and there is currently no standardized protocol for their management. Therefore, this study aimed to summarize renal ADRs related to TKIs use in CML and propose an evidence-based approach to monitor and manage these ADRs.

methodsA systematic literature review was performed to identify renal ADRs associated with TKIs in CML. Two authors screened the search results and extracted data from 37 eligible studies. These findings were then used to develop a scheme for clinicians to monitor and manage these ADRs.

resultsOverall, imatinib seemed to be significantly linked to renal adverse events compared to other TKIs, and switching to dasatinib or nilotinib significantly improved renal function. Similar events were reported with bosutinib, although they were not statistically significant. However, most of the renal events reported on dasatinib were described as nephrotic syndrome that resolved with switching to imatinib. Few cases were reported with nilotinib that described tumor lysis syndrome (TLS)-related kidney injury.

conclusionsRecommendations include monitoring for progressive decline in the estimated glomerular filtration rate with imatinib, nephrotic syndrome with dasatinib, and TLS with nilotinib. Additionally, holding the offending TKI and managing renal ADRs according to local guidelines were adopted more frequently than reducing the TKI dose.
