چکیده

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 controls and patients.

Alpha- 1 Antitrypsin Deficiency in Children: Pulmonary Involvement

Introduction: α1-antitrypsin deficiency (α1-ATD) is one of the most common genetic disorders in white race, a usual cause of liver disease in children, and hepatopulmonary involvement in children and adult. The aim of this case description is presenting a child with early lung disease without liver parenchymal disorder. Case presentation: We describe a 13 year old boy because of exertional dysp...

Deficiency of the chemotactic factor inactivator in human sera with 1 -antitrypsin deficiency.

As revealed by appropriate fractionation procedures, human serum deficient in alpha(1)-antitrypsin (alpha(1)-AT) is also deficient in the naturally occurring chemotactic factor inactivator. These serum donors had severe pulmonary emphysema. Serum from patients with clinically similar pulmonary disease, but with presence of alpha(1)-AT in the serum, showed no such deficiency of the chemotactic f...

Determination of alpha-1 antitrypsin by a nephelometric procedure.

Several reports exist which link low levels of serum alpha-1 antitrypsin with pulmonary emphysema. 3 ’9 ’13 Deficiency of this protein may be detected by serum electrophoresis or specifically quantitated by radial immunodiffusion. Recent investigations have led to the development of a number of automated and manual procedures for the quantitation of immunochemical reactions in aqueous media thr...

Interrelationships between the human alveolar macrophage and alpha-1-antitrypsin.

Alveolar macrophages lavaged from human lungs contain protease activity at an optimum pH of 3.0 and possibly a lesser peak of activity at pH 5.5. Protease activity measured at pH 4.1 is inhibited by purified alpha-1-antitrypsin. Fluorescent antibody studies of human alveolar macrophages showed that alpha-1-antitrypsin is present in normal alveolar macrophages. In addition, macrophages from a pa...

Replacement therapy of alpha 1-antitrypsin deficiency. Reversal of protease-antiprotease imbalance within the alveolar structures of PiZ subjects.

The emphysema associated with the inherited serum deficiency of alpha 1-antitrypsin appears to result from an imbalance between neutrophil elastase and its major inhibitor within the alveolar structures. In the present study we assessed the feasibility of reversing this biochemical defect within the lung via parenteral replacement therapy with an alpha 1-antitrypsin concentrate of normal plasma...
