Improving annual albuminuria testing for individuals with diabetes

Treatment strategies to reduce cardiovascular risk in persons with chronic kidney disease and Type 2 diabetes

Chronic kidney disease (CKD) is a prevalent and progressive condition associated with significant mortality and morbidity. Diabetes is a common cause of CKD, and both diabetes and CKD increase the risk of cardiovascular disease (CVD), the leading cause of death in individuals with CKD. This review will discuss the importance of early detection of CKD and prompt pharmacological intervention to slow CKD progression and delay the development of CVD for improving outcomes. Early CKD is often asymptomatic, and diagnosis usually requires laboratory testing. The combination of estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (UACR) measurements is used to diagnose and determine CKD severity. Guidelines recommend at least annual screening for CKD in at-risk individuals. While eGFR testing rates are consistently high, rates of UACR testing remain low. This results in underdiagnosis and undertreatment of CKD, leaving many individuals at risk of CKD progression and CVD. UACR testing is an actionable component of the CKD definition. A four-pillar treatment approach for slowing the progression of diabetic kidney disease is suggested, comprising a renin-angiotensin-system (RAS) inhibitor, a sodium-glucose cotransporter 2 inhibitor, a glucagon-like peptide 1 receptor agonist, and the nonsteroidal mineralocorticoid receptor antagonist finerenone. The combination of these agents provides a greater cardiorenal risk reduction compared with RAS inhibitors alone. Early detection of CKD and prompt intervention with guideline-directed medical therapy are crucial for reducing CVD risk in individuals with CKD and diabetes. Evidence from ongoing studies will advance our understanding of optimal therapy in this population.

KDOQI US Commentary on the KDIGO 2024 Clinical Practice Guideline for the Evaluation and Management of CKD

The Kidney Disease Outcomes Quality Initiative (KDOQI) convened a work group to review the 2024 KDIGO (Kidney Disease: Improving Global Outcomes) guideline for the management of chronic kidney disease (CKD). The KDOQI Work Group reviewed the KDIGO guideline statements and practice points and provided perspective for implementation within the context of clinical practice in the United States. In general, the KDOQI Work Group concurs with several recommendations and practice points proposed by the KDIGO guidelines regarding CKD evaluation, risk assessment, and management options (both lifestyle and medications) for slowing CKD progression, addressing CKD-related complications, and improving cardiovascular outcomes. The KDOQI Work Group acknowledges the growing evidence base to support the use of several novel agents such as sodium/glucose cotransporter 2 inhibitors for several CKD etiologies, and glucagon-like peptide 1 receptor agonists and nonsteroidal mineralocorticoid receptor antagonists for type 2 CKD in setting of diabetes. Further, KDIGO guidelines emphasize the importance of team-based care which was also recognized by the work group as a key factor to address the growing CKD burden. In this commentary, the Work Group has also assessed and discussed various barriers and potential opportunities for implementing the recommendations put forth in the 2024 KDIGO guidelines while the scientific community continues to focus on enhancing early identification of CKD and discovering newer therapies for managing kidney disease.

Peter WL, Shubrook JH. Type 2 Diabetes and Chronic Kidney Disease: An Opportunity for Pharmacists to Improve Outcomes

Chronic kidney disease (CKD) is an important contributor to end-stage kidney disease, cardiovascular disease, and death in people with type 2 diabetes (T2D), but current evidence suggests that diagnosis and treatment are often not optimized. This review examines gaps in care for patients with CKD and how pharmacist interventions can mitigate these gaps. We conducted a PubMed search for published articles reporting on real-world CKD management practice and compared the findings with current recommendations. We find that adherence to guidelines on screening for CKD in patients with T2D is poor with particularly low rates of testing for albuminuria. When CKD is diagnosed, the prescription of recommended heart-kidney protective therapies is underutilized, possibly due to issues around treatment complexity and safety concerns. Cost and access are barriers to the prescription of newer therapies and treatment is dependent on racial, ethnic, and socioeconomic factors. Rates of nephrologist referrals for difficult cases are low in part due to limitations of information and communication between specialties. We believe that pharmacists can play a vital role in improving outcomes for patients with CKD and T2D and support the cost-effective use of healthcare resources through the provision of comprehensive medication management as part of a multidisciplinary team. The Advancing Kidney Health through Optimal Medication Management initiative supports the involvement of pharmacists across healthcare systems to ensure that comprehensive medication management can be optimally implemented.

Albuminuria: An Underappreciated Risk Factor for Cardiovascular Disease

Albuminuria, an established biomarker of the progression of chronic kidney disease, is also recognized as a biomarker for the risk of cardiovascular disease. Elevated urinary albumin excretion indicates kidney damage and systemic vascular disease, including myocardial capillary disease and arterial stiffness. Albuminuria is associated with an increased risk of coronary artery disease, stroke, heart failure, arrhythmias, and microvascular disease. There are now several therapeutic agents that can lead to albuminuria lowering and a reduction in cardiovascular risk. However, screening for albuminuria is still low. Considering the importance of multidisciplinary management of patients with cardiovascular disease, it is crucial that health care professionals managing such patients are aware of the benefits of albuminuria surveillance and management.
