Evaluation for proteinuria for evaluation of hypertension and use of antihypertensive agents in CKD. Figure is modified from CKD Guideline 5, Fig 57, Fig 57 Rationale for combination of ARBs or ACE inhibitors with diuretics. Schematic depiction of additive antihypertensive effects of the combination of a diuretic and either an ACE inhibitor or an ARB. Volume loss produced by diuretic therapy activates the renin-angiotensin system, blunting the decline in blood pressure. Blockade by either ACE inhibitor or ARB increases the antihypertensive response. because criteria for selection of preferred agents in nondiabetic kidney disease are based on measurements of urine total protein rather than urine albumin.1

ACE Inhibition in Progressive Renal Disease (AIPRD) Study Group Pooled Analysis. Effects on blood pressure (A), urinary protein excretion (B), survival without kidney failure (C), or the combined outcome of doubling of baseline serum creatinine or kidney failure. Patients taking ACE inhibitors (dotted line) and controls (solid line). Follow-up measurements were reported more often during the first 2 years and less often thereafter. Mean blood pressure and mean urine protein excretion during follow-up were defined as the mean of all available follow-up values for each patient. Change during follow-up was defined as the baseline value minus the mean follow-up value for each patient. The number of patients with follow-up data available for analysis of survival without kidney failure is shown below the x-axis of (C). Reprinted with permission.458

ACE Inhibition in Progressive Renal Disease (AIPRD) Study Group Pooled Analysis. Relationship of baseline urinary protein to risk for kidney failure (A) or combined outcome of doubling of baseline serum creatinine or kidney failure (B), or relative risk for these outcomes (C and D). Patients taking ACE inhibitors (squares) and controls (circles). The values above the graphs in (A) and (B) are the fractions of patients with event in the control group (upper row) and ACE inhibitor group (lower row). Relative risks were calculated form multivariable models controlling for significant baseline patient and study characteristics. The solid horizontal line at a relative risk of 1.0 in (C) and (D) indicates no difference between the ACE inhibitor and control groups; the solid and dotted curved lines represent point estimates and 95% CI for the relative risks. P values for tests for interactions between baseline urinary protein excretion and treatment were 0.03 and 0.001, respectively. Reprinted with permission.458

Modification of Diet in Renal Disease (MDRD) Study. Effect of strict blood pressure control on GFR decline. For Study A (baseline GFR 25 to 55 mL/min/1.73 m2), estimated mean (±SE) rates of decline in GFR from baseline to 3 years, based on a 2-slope model are shown. For Study B (baseline GFR 13 to 24 mL/min/1.73 m2), mean (±SE) rates of decline in GFR are estimated from the 1-slope informative censoring model. Closed circles designate the usual blood pressure group; open circles designate the low blood pressure group. The number in parentheses in each column is the total number of patients in both blood pressure groups who had a least one follow-up measurement. Greater baseline proteinuria is associated with a steeper mean GFR decline and with a greater benefit form the low blood pressure goal (P = 0.02 in Study A; P = 0.01 in Study B).

ACE Inhibition and Progessive Renal Disease (AIPRD) Study Group Pooled Analysis. Relative risk for kidney disease progression based on levels of SBP and urinary protein excretion during follow-up. Filled and open symbols show the relative risk for patients with current urine protein excretion ≥1.0 g/d (n = 9,336 visits, 223 events) and <1.0 g/d (n = 13,274 visits, 88 events), respectively. Reference group for each is defined at SBP 110 to 119 mm Hg. Results are from a single multivariable model including two levels for urine protein excretion, six levels for SBP and interaction of current SBP and current urine protein excretion. Covariates include assignment to ACE inhibitor versus control group, gender, age, baseline SBP, baseline diastolic blood pressure, baseline urine protein excretion, baseline serum creatinine concentration (<2.0 or ≥2.0 mg/dL), interaction of baseline serum creatinine and baseline urine protein excretion, interaction of baseline serum creatinine and current urine protein excretion, and study terms.

Determinants of diuretic response. Sodium excretion rate as a function of tubular delivery of diuretic. “A” represents pharmacokinetic determinants of diuretic response for an orally administered diuretic. The solid sigmoidal-shaped dose-response curve has three components: threshold (diuretic delivery rate sufficient to first produce a diuresis); efficiency (rate of delivery that produces an optimal response for any amount of diuretic entering the urine); and maximal response (urinary delivery of diuretic above which no additional diuretic response can occur). “B” represents altered pharmacodynamic determinants in “diuretic resistance,” in which the normal simoidal-shaped curve is shifted downwards and to the right. Diuretic delivery necessary to achieve a threshold response can vary substantially in diuretic resistance.
