Abstract

Objective: To analyze the clinical characteristics of antiphospholipid syndrome (APS) patients with chronic thromboembolic pulmonary hypertension (CTEPH). Methods: A total of 22 APS patients with CTEPH were enrolled in our study, who were admitted in Peking Union Medical College Hospital from January 2012 to August 2018. Diagnoses were confirmed by computed tomographic pulmonary angiography (CTPA), or pulmonary angiography. Demographic characteristics, clinical manifestations, laboratory tests, therapy, World Health Organization (WHO) functional class were retrospectively collected. Results: There were 15 females and 7 males with a median age of 29-year-old. Chest pain (6 cases), dyspnea on exertion (22 cases), cough (6 cases) and hemoptysis (9 cases) were the most common clinical manifestations. Lupus anticoagulant (LA), anticardiolipin (ACL) antibodies and anti-beta 2 glycoprotein Ⅰ (anti-β(2) GPⅠ) antibodies were all positive in 12 patients, two of three antibodies positive in 5 patients, only one positive in 5 patients. The WHO functional classes were Ⅱ-Ⅳ before treatment. Anticoagulants were administrated in all patients. After multidisciplinary evaluation, 9 patients underwent pulmonary thromboendarterectomy (PTE), who al...Continue Reading

Autoimmune Polyendocrine Syndromes

This feed focuses on a rare genetic condition called Autoimmune Polyendocrine Syndromes, which are characterized by autoantibodies against multiple endocrine organs. This can lead to Type I Diabetes.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Autoimmune Polyendocrinopathies

Autoimmune polyendocrinopathies, also called polyglandular autoimmune syndromes (PGASs), or polyendocrine autoimmune syndromes(PASs), are a heterogeneous group of rare diseases characterized by autoimmune activity against more than one endocrine organ, although non-endocrine organs can be affected.
