Epidemiology, major outcomes, risk factors, prevention and management of chronic kidney disease in China

Abstract

Chronic kidney disease (CKD) is common in China. In residents older than 40 years in Beijing, China, 11.3% of subjects had at least one indicator of kidney damage. The primary cause of chronic renal failure in China was glomerulonephritis, which was followed by diabetic nephropathy and hypertensive nephrosclerosis. Renal failure, cardiovascular disease and infection were important complications. IgA nephropathy (IgAN) is the most common CKD in China. The prevalence of hypertension, intrarenal artery lesions and tubulointerstitial lesions in patients with IgAN at the time of renal biopsy was approximately 40, 55 and 85%, respectively. The genetic variation in Megsin confers susceptibility to IgAN in Chinese. The patients with SL/LL genotypes of the MUC20 gene, the 38AA genotype of uteroglobin and DD genotype of the angiotensin-converting enzyme gene had a higher risk of progression. Chinese prospective clinical trials showed that benazepril (BZ) conferred substantial renal benefits in patients with advanced renal insufficiency. The combined therapy with urokinase and BZ was more effective than with BZ alone in reducing proteinuria and protecting renal function in Chinese patients with severe IgAN. Lupus nephritis (LN) is a common form of secondary renal disease diagnosed by renal biopsy in China. Chinese multicenter clinical trials showed that mycophenolate mofetil or leflunomide combined with steroids was effective as induction therapy for proliferative LN. Copyright © 2007 S. Karger AG.
