Highlights
- Early detection and routine screening are crucial for improving kidney disease outcomes.
- Advances in treatment are reshaping CKD care, enhancing quality of life for patients.
Summary and Overview
Chronic kidney disease (CKD) affects about 13.4% of the global population and is marked by gradual kidney function loss, often without early symptoms, leading to delayed diagnosis. Causes include diabetes, hypertension, autoimmune diseases, genetic disorders, and infections, potentially resulting in kidney failure requiring dialysis or transplantation. Early detection through routine screening, especially for high-risk groups, and advances in biomarkers and AI-assisted imaging improve diagnosis and prognosis. Treatment focuses on slowing progression, managing comorbidities, and enhancing quality of life using drugs like SGLT2 inhibitors and renin–angiotensin system blockers. Despite progress, disparities in care and organ availability persist. The disease also impacts mental health and quality of life, highlighting the importance of patient support and advocacy. Ongoing research aims to refine diagnostics, develop therapies, and promote equitable care.
Causes, Risk Factors, and Epidemiology
Diabetes and hypertension are the leading causes of CKD worldwide, damaging kidney filtering units and blood vessels. Other factors include heart disease, infections, nephrotoxins, smoking, genetics, and aging populations. Genetic variants significantly affect certain groups, such as West Africans. CKD prevalence varies globally, highest in North Africa and the Middle East, with early stages common. In 2023, CKD was the ninth leading cause of death, contributing to cardiovascular mortality as well. Aging populations and rising obesity rates drive increasing CKD prevalence, with disparities in care access notably impacting low- and middle-income countries.
Symptoms, Diagnosis, and Pathophysiology
CKD is often asymptomatic until advanced stages, with symptoms like proteinuria and hypertension signaling progression. Diagnosis relies on blood tests measuring creatinine to estimate glomerular filtration rate (GFR), urinalysis for albuminuria, and imaging techniques including ultrasound, MRI, and CT enhanced by AI. Emerging biomarkers like NGAL and KIM-1 aid early detection. Pathophysiologically, inflammation plays a central role, particularly via the NLRP3 inflammasome, which promotes cytokine release and fibrosis. Targeting inflammatory pathways and metabolic dysregulation with therapies such as SGLT2 inhibitors and monoclonal antibodies shows promise in slowing CKD progression.
Prevention, Early Detection, and Treatment
CKD prevention emphasizes early detection through screening high-risk individuals, particularly those with diabetes or hypertension, using blood and urine tests. Guidelines advocate routine testing to identify CKD before symptoms appear and enable timely intervention. Treatment aims to slow disease progression and reduce cardiovascular risks using medications like ACE inhibitors, angiotensin receptor blockers, MRAs, SGLT2 inhibitors, and GLP-1 receptor agonists. SGLT2 inhibitors also provide anti-inflammatory benefits. Patient empowerment, policy initiatives, and global awareness campaigns support prevention and management efforts.
Impact on Quality of Life and Patient Support
CKD adversely affects physical, mental, and cognitive health, causing fatigue, anemia-related symptoms, depression, anxiety, and cognitive impairment. Nutritional factors influence outcomes, with low-protein diets linked to better mental health. Management of anemia improves quality of life, while mental health support through therapy and peer groups is essential. Various online platforms and organizations offer emotional support, education, and resources. Advocacy efforts work to improve care access, fund research, and assist patients facing challenges such as natural disasters or educational barriers.
Advocacy, Community Programs, and Future Directions
Patient advocacy groups like the National Kidney Foundation engage in legislative outreach, education, and community engagement to improve kidney health policies and care access. Programs empower patients through research participation and support networks. Integrating primary care in kidney disease management enhances accessibility, especially in low-income regions. Research advances focus on biomarkers, AI-driven diagnostics, and inflammation-targeting therapies including NLRP3 inhibitors and combination drug regimens. Future efforts aim to standardize assays, personalize treatment, address disparities, and expand patient education to transition CKD care toward precision medicine.
