Chronic kidney disease (CKD) is a leading cause of mortality and morbidity around the world. The prevalence of CKD increases steadily over the past decade in parallel to the rapid expansion of diabetic population. Apart from increased mortality, CKD also has significant impact on quality of life and the economy. The approach to deal with the global CKD epidemic is multifaceted. Early detection by screening high‐risk individuals such as those with hypertension and diabetes is important and cost‐effective. However, low CKD awareness in many countries may impose barriers to early intervention. Hence raising CKD awareness among public and policy makers should be encouraged. In addition, the use of peritoneal dialysis, a less costly and home‐based dialysis modality compared with in‐center haemodialysis, should be promoted to maximize access to dialysis with limited resources. Finally, ongoing research and clinical trials through international collaborations could provide further insight into the pathophysiology of CKD progression, and establish the foundation for development of specific therapeutic agents to retard progression to end stage renal failure. Summary at a Glance: Facing the global healthcare challenges posed by chronic kidney disease (CKD), this review outlines multiple practical strategies to tackle the CKD epidemic.

Abstract: Aim: The reported causes of nephrotic syndrome (NS) varies between different countries. Less is known about the causes of nephrotic‐range proteinuria (NPU). We aimed to evaluate the underlying causes of NS and NPU. Methods: This was a single‐centre, retrospective study of adult patients who underwent renal biopsy between 1983 and 2015 in a tertiary referral hospital in Hong Kong. We determined the distribution of histopathological diagnoses with regard to the age subgroups and time periods. Results: Among 7456 patients who underwent renal biopsy, 982 and 838 patients had NS and NPU, respectively. The most common diagnosis in NS was minimal change disease (MCD) (33.3%), followed by membranous nephropathy (MN) (23.6%) and lupus nephritis (LN) (12.8%); whereas the most common diagnosis in NPU was LN (27.4%), followed by immunoglobulin A nephropathy (IgAN) (21.4%) and diabetic nephropathy (DN) (9.3%). In the NS group, MCD was the most common diagnosis in young adults while MN was the leading cause in the elderly. On the other hand, LN was the most common pathology in the NPU group until the age of 60. Over the past three decades, there was a trend of decrease in the proportion of IgAN in both NS and NPU group, while a combined pathology of hypertensive nephrosclerosis and diabetic nephropathy (HTNS and DN) increased significantly. Conclusions: The causes of NS and NPU in Chinese adults were different and may represent two distinct pathological identities. The spectrum of renal histopathology among these two groups changed significantly over time. [ABSTRACT FROM AUTHOR]
