The kidney's role in these networks is pivotal, as dysfunction can exacerbate systemic diseases, highlighting the need for integrated therapeutic strategies. Chronic kidney disease and acute kidney injury serve as key examples of how kidney dysfunction impacts other organs, leading to complex disease states.

A curative intent for R/R AML usually involves chemotherapy (with or without targeted therapy) with subsequent consolidation, including allogeneic haematopoietic stem cell transplantation. Despite this, long-term survival rates of R/R AML only reach approximately 10% in adults and 40% in children. Given this great unmet clinical need, this review outlines the current and emerging paradigms for preventing and treating R/R AML. Somatic mutations, gene expression, and functional drug testing are important for the selection of small molecule inhibitors of oncogenic signalling pathways (e.g., FLT3), menin inhibitors that disrupt leukemogenic programmes, inhibitors of isocitrate dehydrogenases to restore oncometabolic homoeostasis, and proapoptotic Bcl-2 homology 3 (BH3) mimetics, such as venetoclax. Targeting the recently identified resistance factor SAMHD1 promises to overcome resistance to cytarabine and fludarabine. Given the growing number of potential combinatorial drug regimens and the genetic heterogeneity of AML, real-time <i>ex vivo</i> drug response profiling to guide individualized treatment decisions will become an important complement.

For instance, metformin is renally excreted, and a reduced estimated glomerular filtration rate (eGFR) increases the risk of drug accumulation, potentially leading to serious adverse events such as lactic acidosis. Although sulphonylureas and pioglitazone are primarily metabolized in the liver, their active metabolites are renally excreted, which—particularly in the context of impaired kidney function—may increase the risk of hypoglycaemia or fluid retention, respectively. SGLT2 inhibitors have limited glucose-lowering efficacy in patients with eGFR values below 20–25 mL/min/1.73 m<sup>2</sup>. Additionally, GLP-1 receptor agonists promote weight loss, which may be undesirable in normal-weight patients, and insulin therapy, though often necessary, is associated with a heightened risk of hypoglycaemia and can be challenging to optimize in this vulnerable group. In contrast, the meglitinide repaglinide has been considered a particularly suitable oral agent under these circumstances. It undergoes hepatic metabolism, and only its inactive metabolites are excreted renally. Moreover, repaglinide's short duration of action and meal-time dosing provide safety and additional flexibility in glucose control.</p><p>Dipeptidyl peptidase-4 inhibitors (DPP-4i), such as sitagliptin and linagliptin, have been in clinical use for nearly two decades and are generally regarded as safe, with a favourable side-effect profile. Notably, their risk of inducing hypoglycaemia is significantly lower compared to sulphonylureas and meglitinides. This is attributed to their glucose-dependent mechanism of action, with insulinotropic effects markedly reduced at plasma glucose concentrations below approximately 4.5 mmol/L. Furthermore, DPP-4i are weight-neutral, which may be advantageous for patients with T2D and CKD in the normal or lower body mass index range. The pharmacokinetics of agents within this class vary. Thus, while sitagliptin is primarily excreted unchanged by the kidneys, linagliptin undergoes hepatic metabolism [<span>2</span>]. Consequently, although sitagliptin requires dose adjustment in the context of reduced eGFR, linagliptin does not. Importantly, sitagliptin itself is not considered intrinsically nephrotoxic, even in the setting of advanced CKD. However, despite these favourable characteristics, clinical evidence on the safety and efficacy of DPP-4i in patients with T2D and Stage 5 CKD (eGFR <15 mL/min/1.73 m<sup>2</sup>) remains limited.</p><p>It is therefore timely to highlight the work by Hung et al., ‘Use of dipeptidyl peptidase-4 inhibitors is associated with lower risk of severe renal outcomes in pre-dialysis patients with Type 2 diabetes: A cohort study’ in the Journal of Internal Medicine [<span>3</span>].
