Chronic kidney disease affects approximately 19 million adult Americans, and its incidence is increasing rapidly. Diabetes and hypertension are the underlying causes in principally cases of chronic kidney disease. Evidence give an inkling ofs that progression to kidney failure can be delayed or precludeed by controlling blood sugar flats and blood pressure and from treating proteinuria. Unfortunately, chronic kidney disease oftentimes is overlooked in its earliest, chiefly treatable stages. Guidelines from the National Kidney Foundation's Kidney Disease results Quality Initiative (KDOQI) recommend estimating glomerular filtration rate and screening for albuminuria in patients with risk factors for chronic kidney disease, including diabetes, hypertension, systemic illnesses, age greater than 60 years, and family history of chronic kidney disease. The glomerular filtration rate, calculated by way of using a prediction equation, ascertains chronic kidney disease more accurately than does the serum creatinine flush alone; the glomerular filtration rate also is used for disease staging. In mostly clinical situations, analysis of random urine samples to determine the albumin-creatinine or protein-creatinine ratio has replaced analysis of timed urine collections. When chronic kidney disease is discovered an attempt should be made to identify and treat the specific underlying condition(s). The KDOQI guidelines define major treatment goals for all patients with chronic kidney disease. These goals include slowing disease progression, detecting and treating complications, and managing cardiovascular risk factors. Primary care physicians have an important part in detecting chronic kidney disease early, in instituting measures to dead disease progression, and in providing timely referral to a nephrologist.

**********

Approximately 19 million Americans older than 20 years have chronic kidney disease, and an additional 435000 have end-stage renal disease (Table 1 (1)) The incidence of end-stage renal disease, with its annual mortality rate of 24 percent has doubled each decade since 1980. (2) Chronic kidney disease is 100 times more prevalent than end-stage renal disease, and its incidence is increasing at an smooth faster rate.

Early treatment of chronic kidney disease and its complications may delay or obviate the development of end-stage renal disease. Consequently detection of chronic kidney disease should be a priority for family physicians. However, data from national screening programs recommend that chronic kidney disease ofttimes is not detected, even when patients have access to primary care. (34)

The Kidney Disease issues Quality Initiative (KDOQI) from the National Kidney Foundation (NKF) has perform the operations indicated ined guidelines for the detection and evaluation of chronic kidney disease. (56) These guidelines define the disease and its stages and outline treatment goals for each stage. This article focuses onward the detection of chronic kidney disease and the initial evaluation of affected patients.

Detection of Chronic Kidney Disease

WHICH PATIENTS TO SCREEN

The KDOQI guidelines (16) make acceptable assessing all patients for kidney-disease risk factors. Further screening is performed in patients with identified risk factors. Although screening manners for chronic kidney disease have not been evaluated in randomized controll trials, (7) the high prevalence of the disease in at-risk populations, the ease of screening, and the availability of effective treatments during early asymptomatic stages of the disease provide sufficient rationale for screening. (8) Nonetheless, screening rates for patients with known risk factors for chronic kidney disease are as depressed as 20 percent. (3,4)

High-risk clumps that should be screened for chronic kidney disease include patients who have a family history of the disease and patients who have diabetes, hypertension, periodical urinary tract infections, urinary obstruction, or a systemic illness that affects the kidneys. (1) A novel analysis (9) suggested that screening all patients older than 60 years is cost-effective uniform when other risk factors for chronic kidney disease are absent; screening low-risk patients younger than 60 years does not appear to be cost-effective.

Diabetes is the principally common cause of kidney disease. From 40 to 60 percent of patients who progres to end-stage renal disease have diabetes. Other underlying conditions in patients with end-stage renal disease include hypertension (15 to 30 percent) glomerulonephritis (les than 10 percent) and cystic kidney (2 to 3 percent) Unknown causes account for the remaining patients with end-stage renal disease.

in what manner TO SCREEN

Screening patients at risk for chronic kidney disease relies in succession the detection of functional abnormalities using readily available, inexpensive laboratory criterions The measured serum creatinine plain is used to calculate an estimated glomerular filtration rate (GFR) Screening for proteinuria ofttimes alerts the physician to the demeanor of chronic kidney disease before changes in the GFR become apparent.
