Clinical outcomes in hypertensive patients treated with a single-pill fixed-dose combination of renin-angiotensin system inhibitor and thiazide diuretic.

ABSTRACT: Two or more antihypertensive agents are required to achieve blood pressure control for the most hypertensive patients. However, comparison of clinical outcomes between fixed-dose combinations (FDC) and free-equivalent combinations of renin-angiotensin system (RAS) inhibitor and thiazide diuretic is lacking nowadays. Patients who were newly diagnosed with hypertension between July 1st, 2008 and December 31st, 2011 and prescribed with FDC (n = 13 176) or free combinations of RAS inhibitors and thiazide diuretic (n = 4392) were identified from the National Health Insurance Research Database of Taiwan and matched in 3:1 ratio using the propensity score method. The primary end point was major adverse cardiovascular events (MACE). The secondary end points were hospitalization of heart failure, new diagnosis of chronic kidney disease, and the initiation of dialysis. Compared with he FDC group was associated with better medication adherence compared with the free combination group. FDC of RAS inhibitor and thiazide diuretic reduced MACE (hazard ratio [HR]: 0.85; 95% confidence interval [CI]: 0.74-0.97; P = 0.017), hospitalization for heart failure and initiation of dialysis compared with the free combination regimens. The outcome benefits of FDC was mainly driven by reduced cardiovascular and renal events in the patients with proportion of days covered <80%. In this retrospective claims database analysis, compared with the free combination regimens, the use of FDC of RAS inhibitor and thiazide diuretic was associated with improved medication compliance and clinical outcomes in the management of hypertension, particularly in the patients with poor medication adherence.

Project description:BackgroundTaiwan has the highest renal disease incidence and prevalence in the world. We evaluated the association of statin and renin-angiotensin system inhibitor (RASI) use with dialysis risk in hypertensive patients.MethodsOf 248,797 patients who received a hypertension diagnosis in Taiwan during 2001-2012, our cohort contained 110,829 hypertensive patients: 44,764 who used RASIs alone; 7,606 who used statins alone; 27,836 who used both RASIs and statins; and 33,716 who used neither RASIs or statins. We adjusted for the following factors to reduce selection bias by using propensity scores (PSs): age; sex; comorbidities; urbanization level; monthly income; and use of nonstatin lipid-lowering drugs, metformin, aspirin, antihypertensives, diuretics, and beta and calcium channel blockers. The statin and RASI use index dates were considered the hypertension confirmation dates. To examine the dose-response relationship, we categorized only statin or RASI use into four groups in each cohort: <28 (nonusers), 28-90, 91-365, and >365 cumulative defined daily doses (cDDDs).ResultsIn the main model, PS-adjusted hazard ratios (aHRs; 95% confidence intervals [CIs]) for dialysis risk were 0.57 (0.50-0.65), 0.72 (0.53-0.98), and 0.47 (0.41-0.54) in the only RASI, only statin, and RASI + statin users, respectively. RASIs dose-dependently reduced dialysis risk in most subgroups and in the main model. RASI use significantly reduced dialysis risk in most subgroups, regardless of comorbidities or other drug use (P < 0.001). Statins at >365 cDDDs protected hypertensive patients against dialysis risk in the main model (aHR = 0.62, 95% CI: 0.54-0.71), regardless of whether a high cDDD of RASIs, metformin, or aspirin was used.ConclusionStatins and RASIs independently have a significant dose-dependent protective effect against dialysis risk in hypertensive patients. The combination of statins and RASIs can additively protect hypertensive patients against dialysis risk.

Project description:Rationale & objectiveHeart failure treatment relies on loop diuretics to induce natriuresis and decongestion, but the therapy is often limited by diuretic resistance. We explored the association of renin-angiotensin-aldosterone system (RAAS) activation with diuretic response.Study designObservational cohort.Setting & populationEuvolemic ambulatory adults with chronic heart failure were administered torsemide in a monitored environment.PredictorsPlasma total renin, active renin, angiotensinogen, and aldosterone levels. Urine total renin and angiotensinogen levels.OutcomesSodium output per doubling of diuretic dose and fractional excretion of sodium per doubling of diuretic dose.Analytical approachRobust linear regression models estimated the associations of each RAAS intermediate with outcomes.ResultsThe analysis included 56 participants, and the median age was 65 years; 50% were women, and 41% were Black. The median home diuretic dose was 80-mg furosemide equivalents. In unadjusted and multivariable-adjusted models, higher levels of RAAS measures were generally associated with lower diuretic efficiency. Higher plasma total renin remained significantly associated with lower sodium output per doubling of diuretic dose (β = -0.41 [-0.76, -0.059] per SD change) with adjustment; higher plasma total and active renin were significantly associated with lower fractional excretion of sodium per doubling of diuretic dose (β = -0.48 [-0.83, -0.14] and β = -0.51 [-0.95, -0.08], respectively) in adjusted models. Stratification by RAAS inhibitor use did not substantially alter these associations.LimitationsSmall sample size; highly selected participants; associations may not be causal.ConclusionsAmong multiple measures of RAAS activation, higher plasma total and active renin levels were consistently associated with lower diuretic response. These findings highlight the potential drivers of diuretic resistance and underscore the need for high-quality trials of decongestive therapy enhanced by RAAS blockade.
