The use of renin-angiotensin system(RAS) inhibitors, such angiotensin converting enzyme inhibitors/angiotensin-Ⅱreceptor blockers, to slow progression of chronic kidney disease(CKD) in a large group dominated by elderly people in the real world is not supported by available evidence. Large-scale clinical trials had many faults,among them a lack of focus on the elderly. However,it would be difficult to conduct clinical trials of a similar scale in elderly CKD patients. Besides, progression ofkidney disease is often slow in elderly persons, and the vast majority of older adults with CKD will die before reaching end stage renal disease. Moreover, since it is not clear that progression of kidney disease, and even of proteinuric diabetic nephropathy, is not inhibited through the use of RAS inhibitors, the most patientcentric goal of therapy for many elderly individuals should be individualized.
