A Network Meta-Analysis of Clinical Management Strategies for Treatment-Resistant Hypertension: Making Optimal Use of the Evidence.

ABSTRACT:

Background

With the addition of surgical interventions to current medicinal treatments, it is increasingly challenging for clinicians to rationally choose among the various options for treating patients with apparent treatment-resistant hypertension (ATRHTN). This study aims to establish the comparative effectiveness of mineralocorticoid receptor antagonists (MRA), renal denervation (RDN), darusentan and central arteriovenous anastomosis (CAA) for patients with ATRHTN by performing a network meta-analysis.

Methods

Data Sources: Studies from recent meta-analyses for RDN and placebo effect were supplemented with a systematic search for MRAs in ATRHTN in the Pubmed, EMBASE, CINAHL and Cochrane databases through November 2016.

Study selection

Randomized controlled trials comparing treatment options for patients with ATRHTN.

Data extraction and synthesis

Data were extracted using predefined data extraction forms, including the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. A Bayesian random effects model was used to conduct a network meta-analysis. Spironolactone was used as the main comparator. Main Outcomes and Measures: Reduction in 24-h ambulatory blood pressure measurement (ABPM).

Results

Twenty articles met our inclusion criteria, and seven treatment alternatives were compared. Compared to MRA, CAA had the highest probability of being more effective, further reducing 24-h SBP (-4.8 mmHg [-13.0, 3.7]) and 24-h DBP (-9.7 mmHg [-18, -0.63]). This difference is likely to be clinically meaningful, with a probability of 78 and 96% at a threshold of a 2-mmHg reduction in blood pressure.

Conclusions

When compared to MRA as anchor, darusentan, CAA and RDN are not more effective in achieving a clinically significant reduction in ambulatory blood pressure in individuals with apparent treatment-resistant hypertension.

Project description:ObjectiveTo determine the effectiveness of management strategies for uninvestigated dyspepsia.DesignSystematic review and network meta-analysis.Data sourcesMedline, Embase, Embase Classic, the Cochrane Central Register of Controlled Trials, and clinicaltrials.gov from inception to September 2019, with no language restrictions. Conference proceedings between 2001 and 2019.Eligibility criteria for selecting studiesRandomised controlled trials that assessed the effectiveness of management strategies for uninvestigated dyspepsia in adult participants (age ≥18 years). Strategies of interest were prompt endoscopy; test for Helicobacter pylori and perform endoscopy in participants who test positive; test for H pylori and eradication treatment in those who test positive ("test and treat"); empirical acid suppression; or symptom based management. Trials reported dichotomous assessment of symptom status at final follow-up (≥12 months).ResultsThe review identified 15 eligible randomised controlled trials that comprised 6162 adult participants. Data were pooled using a random effects model. Strategies were ranked according to P score, which is the mean extent of certainty that one management strategy is better than another, averaged over all competing strategies. "Test and treat" ranked first (relative risk of remaining symptomatic 0.89, 95% confidence interval 0.78 to 1.02, P score 0.79) and prompt endoscopy ranked second, but performed similarly (0.90, 0.80 to 1.02, P score 0.71). However, no strategy was significantly less effective than "test and treat." Participants assigned to "test and treat" were significantly less likely to receive endoscopy (relative risk v prompt endoscopy 0.23, 95% confidence interval 0.17 to 0.31, P score 0.98) than all other strategies, except symptom based management (relative risk v symptom based management 0.60, 0.30 to 1.18). Dissatisfaction with management was significantly lower with prompt endoscopy (P score 0.95) than with "test and treat" (relative risk v "test and treat" 0.67, 0.46 to 0.98), and empirical acid suppression (relative risk v empirical acid suppression 0.58, 0.37 to 0.91). Upper gastrointestinal cancer rates were low in all trials. Results remained stable in sensitivity analyses, with minimal inconsistencies between direct and indirect results. Risk of bias of individual trials was high; blinding was not possible because of the pragmatic trial design.Conclusions"Test and treat" was ranked first, although it performed similarly to prompt endoscopy and was not superior to any of the other strategies. "Test and treat" led to fewer endoscopies than all other approaches, except symptom based management. However, participants showed a preference for prompt endoscopy as a management strategy for their symptoms.Systematic review registrationPROSPERO registration number CRD42019132528.
