People worldwide remain undiagnosed with chronic kidney disease

Lancet Chronic kidney disease affects over 844 million people globally, new research suggests, highlighting the need for improved diagnosis and care to reduce the risk of serious complications. The alarming figure is revealed in a study published in The Lancet, a leading medical journal, which warns that nearly half of all cases remain undiagnosed. This means that millions of people are living with the condition without knowing it, and therefore may not be receiving the treatment they need to prevent kidney failure..

The researchers, led by Professor Kazuhiro Shiroma of the University of Queensland, Australia, analysed data from more than 150 countries to estimate the prevalence of chronic kidney disease worldwide. They used various sources of information, including national health surveys, hospital discharge records, and laboratory data. According to their analysis, chronic kidney disease affects about 1 in 10 adults globally, with the condition being more common in low- and middle-income countries..

The study suggests that up to 47% of cases remain undiagnosed, which is a concern because delayed diagnosis can lead to serious consequences. The most significant risk factors for chronic kidney disease are diabetes, high blood pressure, and obesity, which are often linked to unhealthy lifestyles. These conditions can damage the kidneys over time, reducing their ability to filter waste from the blood and perform other vital functions..

If left untreated, chronic kidney disease can progress to end-stage renal disease (ESRD), which requires dialysis or a kidney transplant to sustain life. The researchers stress that early diagnosis and treatment can prevent or delay the progression of the condition, saving millions of people from kidney failure and premature death. In some countries, the lack of access to healthcare services and diagnostic facilities contributes to the underdiagnosis of chronic kidney disease..

This is often seen in areas where medical care is underfunded, and healthcare workers may not have the necessary training or resources to test for and manage the condition. In other countries, the use of urine testing is not standard practice in primary care settings, which can lead to missed opportunities for early diagnosis. The researchers recommend that routine urine testing should be incorporated into healthcare policies to detect kidney disease earlier..

The Lancet study highlights the urgent need for action to address the global burden of chronic kidney disease. The researchers call for healthcare policymakers to prioritize kidney health and invest in education, training, and infrastructure to strengthen the detection and management of the condition. Furthermore, increased awareness among the public and healthcare professionals about the risks and consequences of chronic kidney disease is essential to encourage earlier testing and treatment..

In the United States, the National Kidney Foundation recommends that adults over 40 years old undergo urine testing to detect chronic kidney disease. However, the prevalence of undiagnosed cases suggests that this approach may not be working effectively, especially in low-income minority communities. To address this issue, the foundation has launched initiatives to increase awareness and access to kidney health services among vulnerable populations..

The Lancet study suggests that such efforts should be replicated globally to reduce the burden of chronic kidney disease. The researchers also recommend that healthcare systems should adopt standardised protocols for the diagnosis and management of chronic kidney disease. This includes the use of simple and cost-effective tests, such as urine albumin-to-creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR), to assess kidney function..

Additionally, patients with established kidney disease should receive regular monitoring and treatment to prevent progression. The study authors argue that improved kidney health should be a public health priority, similar to other conditions such as diabetes and hypertension. They suggest that addressing chronic kidney disease will require a multidisciplinary approach, involving healthcare policymakers, healthcare workers, and the public..

By working together, it may be possible to prevent millions of cases of kidney disease worldwide and improve the lives of people affected by this condition. In conclusion, the findings of the Lancet study are a wake-up call for healthcare professionals and policymakers worldwide. By prioritising kidney health and implementing effective diagnostic and treatment strategies, millions of people may be saved from kidney failure and premature death..

The study’s authors hope that their research will inform policy decisions and inspire action to address the global burden of chronic kidney disease. In the long term, addressing the root causes of chronic kidney disease, such as diabetes and hypertension, will require sustained investment in public health initiatives. These might include initiatives to promote healthy diets and lifestyles, as well as education and awareness campaigns to inform people about the risks and consequences of chronic kidney disease..

Moreover, strengthening healthcare systems, particularly in low- and middle-income countries, will be essential to improve diagnosis and treatment outcomes for chronic kidney disease. This may involve training healthcare workers, expanding access to diagnostic facilities, and investing in healthcare infrastructure. As researchers continue to explore the causes and consequences of chronic kidney disease, the need for effective solutions remains urgent..

The Lancet study’s emphasis on the importance of early diagnosis and treatment should inspire policymakers to take action and invest in kidney health initiatives. By taking a proactive approach to kidney health, it may be possible to save millions of people from the consequences of chronic kidney disease. The Lancet researchers are hopeful that their findings will contribute to a shift in focus towards prioritising kidney health and addressing the disparities in healthcare access and services..

Ultimately, reducing the burden of chronic kidney disease will require a coordinated effort from healthcare professionals, policymakers, and the public. By working together, it may be possible to make a difference in the lives of people affected by this condition and to prevent millions of cases of kidney disease worldwide..
