In this interview, Helen Yeh, Vice President, BioPharmaceuticals Medical, Cardiovascular, Renal and Metabolism (CVRM) at AstraZeneca, talks to News-Medical about chronic kidney disease (CKD).
What is the burden of chronic kidney disease (CKD)?
For too long, CKD has been neglected as a priority, although it represents a growing global burden on patients, healthcare systems, and society. CKD affects 840 million people worldwide and is expected to become the fifth leading cause of mortality globally by 2040.1,2
Patients with CKD are at increased risk of cardiovascular (CV) events, poor renal outcomes, and premature death.3,4,5 This disease can also have profound mental health and quality of life implications as it often disrupts a patient’s daily life and activities, especially when on dialysis – leaving them longing for the time back with their loved ones.6
As CKD progresses into later stages, patients may require dialysis or kidney transplantation, which are invasive, time-consuming, and expensive interventions.7,8 Once CKD progresses to kidney failure, annual costs can amount up to USD 100,000 per patient.9 This substantial burden highlights the need for early diagnosis and treatment that can slow disease progression and improve patient outcomes, thus reducing the need for dialysis and other costly late-stage interventions.

Who is most at risk for developing CKD?
Several risk factors are common in people who develop CKD, including diabetes, hypertension, and CV disease. Socioeconomic status, ethnicity, and genetics can impact a patient’s risk of developing the disease as well.10 For example, Asians and African Americans are known to be at higher risk of CKD.10, 11,12
Why is there such a significant unmet need in CKD?
CKD could be called a “silent disease” as many patients do not experience symptoms at earlier stages, making diagnosis more difficult with many patients diagnosed as a consequence of routine testing for other conditions.13, 14 As a result, CKD is vastly underdiagnosed and, in fact, an estimated nine out of 10 patients do not know they have it.10 This often leads to patients being diagnosed only after the disease has already progressed, limiting effective intervention opportunities.
While there are medications available to address some of CKD’s associated conditions, few of them work directly to keep the disease from progressing, emphasizing the need not only for new treatment options but earlier testing and diagnosis. 15
Can CKD be prevented, or progression slowed?
CKD cannot always be prevented, but in some cases, measures can be taken to reduce a patient’s risk. For example, effectively managing conditions that could lead to CKD, such as diabetes or high blood pressure, can lower a patient’s chances of developing CKD.16 Diagnosing CKD early when the disease is in its initial stages is also important, as intervening early can slow disease progression, preserve kidney function, and reduce complications.10,15
At-risk individuals can also make lifestyle changes such as adopting healthier eating habits and quitting smoking to improve their general health and reduce their risk of developing complications such as obesity or CV disease.16
How can we improve earlier detection and diagnosis?
The first stop for many patients at risk of developing CKD is usually a visit to their primary care physician (PCP). By making testing a regular part of a patient’s check-ups, we can improve early detection and diagnosis chances at an early stage.
Regularly checking the estimated glomerular filtration rate (eGFR) on a patient’s metabolic panel helps measure the level of kidney function and supports early diagnosis.18 It is an easy test to integrate as part of a patient’s check-up, much like existing screenings for blood pressure, glucose, and cholesterol. Additionally, a simple urine test to check for albuminuria can help detect kidney damage.10
Through these two simple tests, it is possible to diagnose and understand patients’ future risks for CKD. Timely intervention is essential to prevent or slow disease progression, and the tools to do so are readily available.10
What challenges do PCPs face when diagnosing CKD?
It is never easy to deliver a tough diagnosis that can be life-changing and CKD is no exception. It is critical that we ensure PCPs have adequate information and tools to talk to their patients about CKD. Towards this end, we have launched “The Pressure is On” – a new campaign to raise awareness and empower PCPs to step into their crucial roles in the prevention, diagnosis, and management of CKD. The campaign provides a range of information and patient counseling resources to support physicians in diagnosing and explaining CKD to their patients.
Why should PCPs and patients have conversations about earlier diagnosis?
While patients may not feel CKD symptoms early on, the intraglomerular pressure is building inside their kidneys. If left unchecked, this pressure can cause irreversible damage to nephrons – leading to reduced kidney function, poor outcomes, and, ultimately, lower quality of life. These initial conversations about CKD are the key building blocks for successful early intervention, which has been shown to slow disease progression in CKD patients and reduce the risk of complications.
Where can readers find more information?
We hope PCPs will visit www.diagnose-ckd.com, where a range of resources are available.
