A case of non-cirrhotic portal hypertension in a patient with systemic lupus erythematosus, the first of our knowledge, is described. Severe pulmonary hypertension was associated with the portal hypertension and with markers of active auto-immunity. Pulmonary hypertension has not previously been associated with non-cirrhotic portal hypertension. The coexistence of vasculopathy of the portal and...
Three patients with primary pulmonary hypertension and one man with suspected thromboembolic pulmonary hypertension were given up to 300 mg diazoxide by injection into the pulmonary artery. The three patients with primary pulmonary hypertension responded with a fall in total pulmonary resistance and a rise in cardiac output. The patient with suspected thromboembolic pulmonary hypertension did n...
This report describes a patient who developed pulmonary hypertension 6 years after lung transplantation for primary pulmonary hypertension (PPH). Evaluation with right heart catheterization followed by pulmonary angiography, however, demonstrated that the pulmonary hypertension was secondary to an anastomotic narrowing of the pulmonary artery, rather than a recurrence of her PPH. Vascular compl...
Current guideline-recommended screening for pulmonary hypertension in patients with systemic sclerosis has not been evaluated in systemic lupus erythematosus (SLE), which is disproportionately prevalent in Asians. This multicentre, cross-sectional screening study aims to study the prevalence of pulmonary hypertension among SLE patients using these guidelines, and identify independent predictors...
OBJECTIVE To examine sporadic cases of primary pulmonary hypertension of coancestry. DESIGN An epidemiologic study of families of patients with primary pulmonary hypertension. SETTING A university-affiliated referral population. PARTICIPANTS Family members of 13 patients with primary pulmonary hypertension. MEASUREMENTS Family pedigrees involving grandparents, parents, siblings, and chi...
Limited literature sources implicate mast-cell mediator chymase in the pathologies of pulmonary hypertension and pulmonary fibrosis. However, there is no evidence on the contribution of chymase to the development of pulmonary hypertension associated with lung fibrosis, which is an important medical condition linked with increased mortality of patients who already suffer from a life-threatening ...
Pulmonary hypertension is characterized by elevated pulmonary arterial pressure and secondary right ventricular failure. A thromboembolic occlusion of the proximal or distal pulmonary vasculature results in chronic thromboembolic pulmonary hypertension. We report an uncommon case that presented to our hospital with symptoms of dyspnea on exertion over 2 years. The patient had been treated for p...
Objective: Rare disease Background: Pulmonary Langerhans cell histiocytosis (PLCH) can be associated with pulmonary hypertension, although this association is more prevalent with other interstitial lung diseases. However, the diagnosis and effective treatment strategies for PLCH-associated pulmonary hypertension remain controversial. Case Report: A 27-year-old woman, who was an ex-smoker, was d...
Pulmonary arterial hypertension affects the distal pulmonary vasculature causing intimal, medial, adventitial fibrosis, thickening and periadventitial changes leading to progressive increase in pulmonary vascular resistance and pulmonary arterial pressure [1]. Pulmonary hypertension (PH) is defined as mean pulmonary artery pressure equal to or greater than 25 mm Hg at rest. PH is classified int...
