Recommendations for screening and detection of connective tissue disease-associated pulmonary arterial hypertension.

ABSTRACT: Pulmonary arterial hypertension (PAH) affects up to 15% of patients with connective tissue diseases (CTDs). Previous recommendations developed as part of larger efforts in PAH did not include detailed recommendations for patients with CTD-associated PAH. Therefore, we sought to develop recommendations for screening and early detection of CTD-associated PAH.We performed a systematic review of the literature on the screening and diagnosis of PAH in CTD. Using the RAND/University of California, Los Angeles consensus methodology, we developed case scenarios followed by 2 stages of voting. First, international experts from a variety of specialties voted anonymously on the appropriateness of each case scenario. The experts then met face-to-face to discuss and resolve discrepant votes to arrive at consensus recommendations.The key recommendation stated that all patients with systemic sclerosis (SSc) should be screened for PAH. In addition, patients with mixed connective tissue disease or other CTDs with scleroderma features (scleroderma spectrum disorders) should be screened for PAH. It was recommended that screening pulmonary function tests (PFTs) with single-breath diffusing capacity for carbon monoxide, transthoracic echocardiogram, and measurement of N-terminal pro-brain natriuretic peptide (NT-proBNP) be performed in all patients with SSc and scleroderma spectrum disorders. In patients with SSc and scleroderma spectrum disorders, transthoracic echocardiogram and PFTs should be performed annually. The full screening panel (transthoracic echocardiogram, PFTs, and measurement of NT-proBNP) should be performed as soon as any new signs or symptoms are present.We provide consensus-based, evidence-driven recommendations for screening and early detection of CTD-associated PAH. It is our hope that these recommendations will lead to earlier detection of CTD-associated PAH and ultimately improve patient outcomes.

Project description:ObjectivesFew studies have focused on pulmonary arterial hypertension (PAH) associated with connective tissue diseases (CTDs). The optimal treatment for CTD-PAH has yet to be established.DesignMeta-analysis of the data from evaluations of treatment for PAH generally (19 studies) and CTD-PAH specifically (nine studies) to compare the effects of pulmonary vasodilative PAH agents. MEDLINE, EMBASE and BIOSIS were searched. English-language full-text articles published between January 1990 and August 2012 were eligible.SettingInternational.ParticipantsPatients with PAH generally (n=3073) and CTD-PAH specifically (n=678).Primary outcome measureExercise capacity (6 min walk distance, 6 MWD).ResultsPatients with PAH (all forms) had mean age 32-55 years (women, 61-87%); CTD-PAH patients had mean age 45-55 years (women, 74-95%). Overall estimate of mean change in 6 MWD from baseline (95% CI) for the active treatment group versus the control group in all patients with PAH was 34.6 m (27.4-41.9 m). Pooled mean differences from the results for patients receiving placebo by subgroup of patients receiving phosphodiesterase (PDE)-5 inhibitors, endothelin receptor antagonists (ERAs) and prostacyclin (PGI2) analogues were 22.4-45.5, 39.5-44.2 and 12.4-64.9 m, respectively. Overall estimate of mean difference between changes in 6 MWD in patients with CTD-PAH was 34.2 m (23.3-45.0 m). Pooled mean differences by subgroup of patients receiving PDE-5 inhibitors, ERAs and PGI2 analogues in patients with CTD-PAH were 37.0-47.1, 14.1-21.7 and 21.0-108.0 m, respectively. ERAs were less effective in patients with CTD-PAH than all-form patients with PAH: 14.1 m (-4.4-32.6 m) vs 39.5 m (19.5-59.6 m) for bosentan and 21.7 m (2.2-41.3 m) vs 44.2 m (30.2-58.2 m) for ambrisentan.ConclusionsAll three types of PAH agent are effective. However, ERAs may be a less effective choice against CTD-PAH; further studies are needed. Limitations include the limited number of studies for some agents and for patients with CTD-PAH.
