Angiotensin Converting Enzyme (ACE2), Brain, Gut Dysbiosis in Pulmonary Hypertension

Pulmonary Arterial Hypertension Clinical Trial

Official title:
Angiotensin Converting Enzyme (ACE2), Brain, Gut Dysbiosis in Pulmonary Hypertension

Clinical Trial Summary

Pulmonary arterial hypertension (PAH) is fatal with right heart failure due to raised pulmonary vascular pressure. Gut dysbiosis was identified in animals with pulmonary hypertension. Deidentified human samples will be tested for gut dysbiosis in PAH, circulating bacterial metabolites and markers of inflammation and gut leakiness. The gut microbiome and circulating metabolites, markers of inflammation and gut leakiness of PAH patients and healthy subjects will be compared in deidentified fecal samples and blood.

Clinical Trial Description

Stool samples will be collected from people with no, mild-moderate or severe pulmonary arterial hypertension. Bacterial DNA will be extracted from the feces and sequenced by whole genome sequencing (shotgun sequencing). The DNA sequences will be used to identify the bacteria present in the feces, and to model the functions of the gut microbial community in each of the three groups. This will test for gut dysbiosis in pulmonary arterial hypertensive patients compared to healthy subjects. Gut dysbiosis is a condition where the gut bacterial communities are unbalanced and has been implicated in disease processes. In subjects recruited in the USA, blood samples will be tested for markers of gut leakiness and inflammation as well as gut bacterial metabolites found in the circulation. ;
