Serum alpha 1 antitrypsin and pulmonary emphysema.
Using isoelectric focusing (IEF) and radial immunodiffusion (RID) techniques, serum samples from 100 normal healthy adults and 21 patients with pulmonary emphysema were analysed to identify various alpha 1 antitrypsin phenotypes and the serum concentrations. Ten percent of the patients had low serum values. The normal or most common genetic form, MM, is the predominant phenotype in both control...
متن کاملAlpha 1-antitrypsin-deficiency-related emphysema.
BACKGROUND A congenital cause of emphysema resulting from alpha 1-antitrypsin (A1AT) deficiency affects 1 in 2500 individuals and could account for emphysema in 2 percent of all persons with emphysema. Individuals aged 30 to 45 years with chronic shortness of breath and coughing could have A1AT deficiency. METHODS Using the key words "alpha 1-antitrypsin deficiency," "chronic obstructive pulm...
متن کاملAlpha-1 antitrypsin Null mutations and severity of emphysema.
BACKGROUND Alpha-1 antitrypsin (AAT) deficiency is an autosomal-codominant disorder, caused by mutations in the SERPINA1 gene on chromosome 14. Individuals affected by the most common mutations, SZ and ZZ, have serum AAT concentrations of 25% and 15% of normal levels, and present a higher risk of emphysema. Mutations causing total absence of serum AAT (Null mutations) were suggested to be assoc...
متن کاملThe Role of Alpha–1 Antitrypsin in Emphysema
Alpha-1 antitrypsin (AT) is a member of the serine proteinase inhibitor (SERPIN) superfamily. It is an acute phase protein produced constitutively, primarily by hepatocytes, and is secreted in to the plasma from where it diffuses into the lung. AT is the most abundant proteinase inhibitor within the lung whose main physiological role is to regulate neutrophil elastase (NE) liberated from activa...
متن کاملAlpha-1 antitrypsin deficiency with severe pulmonary emphysema.
Alpha-1 antitrypsin (AAT) deficiency is a hereditary disorder characterized by an early onset of emphysema. While this disease is common in the Caucasian population, it is quite rare in Japan. To date, only 15 traits have been reported and it can be speculated that many cases of this genetic deficiency may have been overlooked. We report an additional case of AAT deficiency with severe emphysem...
