Schistosomiasis Pulmonary Arterial Hypertension [PDF]

open access: yesFrontiers in Immunology, 2020
Pulmonary arterial hypertension (PAH) is a disease of the lung blood vessels that results in right heart failure. PAH is thought to occur in about 5% to 10% of patients with hepatosplenic schistosomiasis, particularly due to S. mansoni. The lung blood vessel injury may result from a combination of embolization of eggs through portocaval shunts into the

Genetics of Pulmonary Arterial Hypertension [PDF]

open access: yesSeminars in Respiratory and Critical Care Medicine, 2009
Tremendous progress has been made in understanding the genetics of pulmonary arterial hypertension (PAH) since its description in the 1950s as a primary disorder of the pulmonary vasculature. Heterozygous germline mutations in the gene coding bone morphogenetic receptor type 2 (BMPR2) are detectable in the majority of cases of heritable PAH, and in ...

Oxidative stress-dependent activation of collagen synthesis is induced in human pulmonary smooth muscle cells by sera from patients with scleroderma-associated pulmonary hypertension [PDF]

open access: yes, 2014
Pulmonary arterial hypertension is a major complication of systemic sclerosis. Although oxidative stress, intima hyperplasia and a progressive vessel occlusion appear to be clearly involved, the fine molecular mechanisms underpinning the onset and ...

Plasma proteome analysis in patients with pulmonary arterial hypertension: an observational cohort study [PDF]

open access: yes, 2017
BackgroundIdiopathic and heritable pulmonary arterial hypertension form a rare but molecularly heterogeneous disease group. We aimed to measure and validate differences in plasma concentrations of proteins that are associated with survival in patients ...

Paediatric pulmonary arterial hypertension: updates on definition, classification, diagnostics and management

open access: yesEuropean Respiratory Journal, 2019
Paediatric pulmonary arterial hypertension (PAH) shares common features of adult disease, but is associated with several additional disorders and challenges that require unique approaches.

Echocardiographic assessment of pulmonary hypertension: a guideline protocol from the British Society of Echocardiography. [PDF]

open access: yes, 2018
Pulmonary hypertension is defined as a mean arterial pressure of ≥25 mmHg as confirmed on right heart catheterisation. Traditionally, the pulmonary arterial systolic pressure has been estimated on echo by utilising the simplified Bernoulli equation from ...
