The status of the blood kinin system, activity of serum inhibitors of proteinases (alpha 1-protease inhibitor and alpha 2-macroglobulin) as well as indices of activity of trypsin-like proteinases, elastolytic and fibrinolytic activity, free antitryptic activity and complete content of acid stable
Sarcoidosis is a disease of unknown etiology characterized by noncaseating epithelioid granulomas, oligoclonal CD4(+) T cell infiltrates, and immune complex formation. To identify pathogenic antigens relevant to immune-mediated granulomatous inflammation in sarcoidosis, we used a limited proteomics
The balance between proteases and antiproteases in the lower respiratory tract is believed to play a role in the outcome of interstitial lung diseases. In this cross-sectional study, we measure several phagocyte derived enzymes, namely plasminogen activator, neutrophil elastase and an ill-defined
BACKGROUND
The search for gene candidates in multifactorial diseases such as sarcoidosis can be based on the integration of linkage association data, gene expression data, and protein profile data from genomic, transcriptomic and proteomic studies, respectively.
METHODS
In this study we performed a
Elastase activities were investigated in bronchoalveolar lavage (BAL) cells from healthy controls (C, n = 8) and patients with untreated mediastinopulmonary sarcoidosis at different stages: I (n = 5), II (n = 7), IIIA (n = 3), IIIB (n = 4). Elastase activities (EA and ELA) were measured against a
The intensity of inflammatory response was evaluated in skin test on guinea pig using bronchoalveolar lavage (BAL) fluid obtained from patients with some diseases of the respiratory tract. The results of skin test were verified with activities of proteases in BAL fluid. The study was performed on 24
Pulmonary sarcoidosis involves development of parenchymal granulomata that usually resolve spontaneously; however, it remains unclear what pathogenic mechanisms are responsible for the progression to local or diffuse fibrosis with irreversible lung remodeling that occurs in 20% of patients. Alveolar
We wanted to determine whether cell populations and soluble components in bronchoalveolar lavage (BAL) could be useful in predicting the outcome of lung function and chest radiography in patients with untreated pulmonary sarcoidosis. Analysis of soluble proteins in BAL fluid, included the levels of
BACKGROUND
This is the first ophthalmic report--to our knowledge--of an anterior uveitis secondary to sarcoidosis in a patient infected with human immunodeficiency virus (HIV). Other reported causes of uveitis in HIV-infected patients have included HIV, herpes zoster, tuberculosis, syphilis,
One feature of pulmonary sarcoidosis is an increase of lymphocyte numbers in bronchoalveolar lavage fluid (BALF). In some patients the number of polymorphonuclear neutrophils (PMN) also rises. It has been suggested that the prognosis for the latter subjects is likely to be worse than that for the
A thermolysin-like metalloendopeptidase, optimally active at a neutral pH, was identified in human serum. The enzyme cleaves the synthetic substrate glutaryl-Ala-Ala-Phe-2-naphthylamide at the Ala-Phe bond. Activity was determined by measuring the rate of formation of Phe-2-naphthylamide in a
Cystatin C belongs to the group of wide spread extracellular cysteine protease inhibitors. Using ELISA kits it was shown that the highest cystatin C concentration was in human cerebrospinal fluid and low cystatin C concentration was in human urine. In healthy young persons serum cystatin C
Proteolytic and antiproteolytic activities were studied in bronchoalveolar lavages of 102 patients with sarcoidosis of respiratory tissues, exogenous allergic and idiopathic fibrotic alveolitis. Deficiency of the antiproteolytic activity was observed in all the impairments studied, whereas
