Plasma renin activity (PRA) levels and antihypertensive drug use in a large healthcare systemJohn J Sim
Division of Nephrology and Hypertension, Kaiser Permanente Los Angeles Medical Center, Los Angeles, California, USA
Am J Hypertens 25:379-88. 2012..To evaluate the heterogeneity of hypertension and the medication burden associated with it, we investigated medication usage in relation to PRA among hypertensive patients within a large ethnically diverse organization...- Indinavir-induced nephrolithiasis three and one-half years after cessation of indinavir therapyJulie Huynh

Int Urol Nephrol 43:571-3. 2011..5 years after discontinuing indinavir. We use this case to illustrate the pathophysiology of indinavir stones and hypothesize how they can occur years after discontinuation by discussing the pharmacokinetics of the drug... - Association of plasma renin activity and aldosterone-renin ratio with prevalence of chronic kidney disease: the Kaiser Permanente Southern California cohortJohn J Sim
