Interferon gamma release assays based on M. tuberculosis-specific antigens in sarcoidosis patients.

Introduction: This study is a part of the project on interferon gamma release assays performed in the group of untreated sarcoidosis patients formerly BCG vaccinated. The aim of the study was to assess the rate of positive commercial interferon g release assays in sarcoidosis patients. We discussed the results in the context of hypothesis that M.

[Prevalence of latent infection with Mycobacterium tuberculosis in Mazovia Region using interferon gamma release assay after stimulation with specific antigens ESAT-6 and CFP-10].

Introduction: Over 8000 cases of tuberculosis (TB) are diagnosed annually in Poland. People infected with Mycobacterium tuberculosis (MTB) have a risk of active disease around 10% during whole life, the risk is biggest in the first two years after infection. Recognizing infection before TB disease occurred enables prophylaxis against its activation and ceases transmission of infection.

Angiogenic activity of sera from patients with systemic autoimmune diseases in relation to clinical, radiological, and functional pulmonary status.

Systemic autoimmune diseases, such as vasculitis and collagen diseases, are characterized by chronic inflammation. Mutual interrelationship between angiogenesis and chronic inflammation has already been demonstrated. The aim of the study was to examine the effect of sera from patients with systemic autoimmune diseases on angiogenesis induced by human mononuclear cells.

Angiogenic activity of sera from silicosis and pulmonary Langerhans cell histiocytosis patients in relation to lung function tests.

Angiogenesis has been implicated in the pathogenesis of interstitial lung diseases. A correlation between serum angiogenic cytokines level of patients with idiopathic pulmonary fibrosis and radiographic manifestations or functional pulmonary changes has been described, but the role of angiogenesis in the pathogenesis of other interstitial lung diseases such as silicosis and pulmonary Langerhans cell histiocytosis remains unclear. The aim of the study was to examine the effect of sera from silicosis and pulmonary Langerhans cell histiocytosis patients on angiogenesis induced by human mononuclear cells (MNC) in relation to pulmonary function.

Modulatory effect of sera from patients with various types of pulmonary fibrosis on mononuclear cell induced angiogenesis in relation to pulmonary function.

Angiogenesis plays an important role in the pathogenesis of idiopathic pulmonary fibrosis. Pulmonary fibrosis occurs also in many diseases, such as other types of interstitial pneumonias or drug-induced pulmonary fibrosis. The aim of the study was to examine the effect of sera from patients with various types of pulmonary fibrosis on angiogenesis induced by human mononuclear cells (MNC) in relation to lung functions.
