Risk factors for CKD are similar to those for other NCDs • Diabetes • Age, minority status • Hypertension • UTI, nephrolithiasis • Relative with CKD • Acute renal failure • CV disease • UT obstruction • Chronic infections • Nephrotoxins • Smoking, obesity, dyslipidemia NKF-K/DOQI, 2002

The global burden of CKD is greatest in developing countries and in the poor

The global burden of CKD is greatest in developing countries and in the poor Territories are sized in proportion to the absolute number of people who die of CKD each year. Even within countries, burden of CKD is concentrated among the poorest. Renal replacement is available only to a wealthy few. White et al, WHO Bull 2008; Nugent et al, NCP 2011

Most people affected by CKD are unaware Individuals who were aware that they had CKD e. GFR (ml/min/1. 73 m 2) - NHANES 1988 -94 and 1999 -2000 surveys in the US general population (19, 589); Adults aged 20 years and older; - China National Survey of Chronic Kidney Disease; Adults aged 18 years and older; - Self-reported awareness of CKD - Awareness of CKD is even lower in developing countries Coresh et al, JASN 2005; Zhang et al. Lancet, 2012

Detecting CKD is cheap and efficient • Kidney function (e. GFR) estimated using simple equations applied to results of blood test (serum creatinine; $0. 75) • Albuminuria detected using semi-quantitative urine dipstick ($0. 02) or quantitative urine albumin: creatinine ratio ($2. 50) • Consistent presence of low e. GFR or abnormal albuminuria indicates presence of CKD NKF-K/DOQI, 2002

Inexpensive treatments for CKD improve CV and renal outcomes • • • Control of hypertension ACEI or ARB use Statin use Control of blood sugar (in diabetic patients) Smoking cessation Prevention of obesity Remuzzi, Lancet 2012

Summary • CKD is common, expensive, and associated with very poor outcomes • CKD

Summary • CKD is common, expensive, and associated with very poor outcomes • CKD often coexists with other NCDs • Many of the affected are unaware…but CKD is cheaply and easily detected using routine tests • Effective and cost-effective treatments for CKD are available • Detection and management of CKD should be integrated into national NCD programs
