Genomic Features

We apply a pattern-based classification method to identify clinical and genomic features associated with the progression of Chronic Kidney disease (CKD). We analyze the African-American Study of Chronic Kidney disease with Hypertension dataset and construct a decision-tree classification model, consisting 15 combinatorial patterns of clinical features and single nucleotide polymorphisms (SNPs), seven of which are associated with slow progression and eight with rapid progression of renal disease among African-American Study of Chronic Kidney patients. We identify four clinical features and two SNPs that can accurately predict CKD progression. Clinical and genomic features identified in our experiments may be used in a future study to develop new therapeutic interventions for CKD patients.

Measurement of GFR is considered the standard for estimating renal function. However, standardized accurate GFR methodology is expensive and cumbersome; therefore, estimates of GFR based on serum creatinine concentration have been employed. The purpose of the study presented here was to assess the accuracy and precision of using serum creatinine measurements to estimate GFR in the screen cohort of The African-American Study of Kidney Disease and Hypertension (AASK) Pilot Study. GFR was estimated by four methods: 100/serum creatinine, Cockcroft-Gault equation, creatinine clearance from 24-h urine collection, and a new regression equation derived from the pilot study data. These methods were compared with renal clearance of 125I-iothalamate GFR (GFR1) in 193 hypertensive (diastolic blood pressure > or = 95 mm Hg) African-American screen (142 men, 51 women). A second GFR (GFR2) was performed in 98 screen who were eligible (GFR1 25-70 mL/min per 1.73 m2) for the pilot study. Accuracy was assessed by the difference of 125I-iothalamate GFR-estimated GFR (delta GFR), and precision was estimated from the combined root mean squared error (CRMSE) and the coefficient of determination (r2). The results for accuracy (+/- SD) and precision were as follows: (1) 100/Scr, delta GFR = -0.76 +/- 16.5, CRMSE = 16.5, r2 = 0.69; (2) Cockcroft-Gault, delta GFR = 9.56 +/- 14.9, CRMSE = 17.7, r2 = 0.66; 3) 24-h creatinine clearance, delta GFR = 0.79 +/- 20.7, CRMSE = 20.7, r2 = 0.49; 4) New equation delta GFR = -0.08 +/- 12.8, CRMSE 12.7, r2 = 0.75. In comparison, a second GFR (GFR2, N = 98) had delta GFR = 1.36 +/- 8.48, CRMSE 8.6, r2 = 0.75. Estimates based on 100/SCr and the new equation were the most precise. It was concluded that GFR estimated by serum creatinine is superior to outpatient 24-h urine creatinine clearance in this population. Serum creatinine values can be used to provide a reasonably accurate estimate of GFR in hypertensive African Americans.
