High-resolution computed tomography (HRCT) is a useful method for quantifying the extent of emphysema. Few reports have mentioned the relationships between HRCT scans and pulmonary function tests in chronic obstructive pulmonary disease (COPD). For diagnosis, COPD requires chronic airflow limitation and emphysema and/or chronic bronchitis. We examined 20 who were previous smokers with middle to moderate...
Charcot-Marie Tooth disease (CMT) encompasses several inherited peripheral motor-sensory neuropathies and is one of the most common inherited neuromuscular diseases. Charcot–Marie–Tooth disease can be associated with several disorders that may be encountered by the pulmonary physician, including restrictive pulmonary impairment, sleep apnea, restless legs, and vocal cord dysfunction. Restrictive pulmonary...
Extrinsic allergic alveolitis (EAA) caused by inhaled organic environmental allergens can progress to a fibrotic end-stage lung disease. Neovascularization plays an important role in pathogenesis of pulmonary fibrosis. The aim of this study was to assess the effect of sera from EAA patients on the angiogenic capability of normal peripheral human mononuclear cells (MNC) in relation to the clinical,...
Study Objectives The etiology and prevalence of pulmonary hypertension (PH) in patients with stable chronic obstructive pulmonary disease (COPD) is uncertain. This study was done to determine the prevalence of PH in stable COPD outpatients and to evaluate the relationship between PH and indices of pulmonary function. Design The study was a retrospective review of outpatients with COPD and PH defined...
Purpose Although computed tomography (CT) has been used previously to assess disease severity in lymphangioleiomyomatosis (LAM), the associations between the extent of pulmonary cysts on CT and six-minute walk test (6MWT), matrix metalloproteinases (MMPs) and vascular endothelial growth factor (VEGF-D) are not well established. We performed a cross-sectional study to quantify the extent of pulmonary...
Activation of blood coagulation pathways as a component of an allergic response has been studied in animal models. In patients with allergic diseases, clot qualities have been noted to be different in terms of denser fibrin clot with reduced plasmin-mediated clot lysis. Correlation between occupational hypersensitivity pneumonitis (HP) with thromboembolic events is scarce in the general patient population...
Introduction Serum vascular endothelial growth factor-D (VEGF-D) is a lymphangiogenic growth factor that is considered a valuable tool in the diagnosis of lymphangioleiomyomatosis (LAM). Previous studies have reported a wide variability in VEGF-D serum levels in LAM patients and it seems to be associated with pulmonary impairment and lymphatic involvement. Methods We conducted a cross-sectional...
