Determination of Alpha-1 Antitrypsin Level in Patients with Severe Asthma

چکیده
BACKGROUND This descriptive study aimed to determine the serum level of alpha-1 antitrypsin (AAT) in patients with severe asthma. MATERIALS AND METHODS The serum level of AAT was determined in 43 patients with severe asthma. Pulmonary function tests were performed and data were analyzed by SPPS version 19 software. RESULT The mean age of patients was 41±13.8 years (range 14 to 78 years). The AAT level was within the normal range (90-200 mg/dl) in 38 patients (88.4%) and less than normal in 2 patients (4.7%). CONCLUSION No association was observed between the serum level of AAT and lung function in severe persistent asthmatic patients. The prevalence of AAT deficiency was low in patients with severe persistent asthma. These results must be confirmed by further longitudinal investigations using larger cohort studies.

Alpha 1-antitrypsin (AAT) or alpha 1-protease inhibitor (PI) is the principal inhibitor of proteolytic enzyme in serum. Its phenotypic variability has been reported to be associated with liver, lung diseases and rheumatoid arthritis in humans. There is much documentation about high risk phenotypes of PI in some regions of the world, however, there are no reliable reports on these phenotypes and...

ABSTRACT Alpha 1-Antitrypsin is one of the most important serine protease in human serum,inhibiting several proteases.As an inhibitor of proteases it is a non-specific lever in humoral defence of the body. Its level increases significantly under the infections condition of pregnancy. The health of lung,too, depends on maintaininig the equilibrium of protease antitrypsin ,and Alpha 1-trypsin p...

Objective(s):Psoriasis is an autoimmune disease that appears on the skin. Although psoriasis is clinically and histologically well characterized, its pathogenesis is unknown in detail. The aims of this study were to evaluate the proteome of psoriatic patients' sera and to compare them with those of normal healthy human to find valuable biomarkers. Materials and Methods: In a case-control study,...
