All the patients were tested for the presence of S and Z alleles for alpha 1 antitrypsin deficiency using polymerase chain reaction. Defkciencia this study, three patients diagnosed with an A1AT deficiency had neonatal cholestasis and in two of akfa, before a definite diagnosis of the deficiency was established, the cholestasis was considered idiopathic.
Rapid nonradioactive detection of mutations in the human genome by allele-specific amplification. The treatment of the lung disease is the same, although exogenous AATD augmentation is indicated when lung function deteriorates.
The mutant alleles S and Z of the alphaantitrypsin gene were investigated in the 12 children. Relationship of chronic sputum expectoration to physiologic, radiological and health status characteristics in alphaantitrypsin deficiency PiZ. Effect of administration of a combined strogen-progestin contraceptive on the level of individual plasma proteins. Objective – The purpose of this study was to use DNA analysis to examine the presence of an alphaantitrypsin deficiency in 12 children suspected of having this deficiency and who showed laboratory and clinical characteristics of the disease.
J Clin Invest,pp. Lung volume reduction surgery for patients with alpha-1 antitrypsin deficiency emphysema. Hepatic morphology in inherited metabolic diseases. Am J Med Genet ; The treatment of the lung disease is the same, although exogenous AATD augmentation is indicated when lung function deteriorates. The lack of AATD in the lung favors the development of emphysema, since the proteolytic effect of elastases — the main biological function of AATD — is not counteracted.
The principal prognostic factor in these patients is forced expiratory volume in one second FEV 1which is affected mainly by exposure to tobacco smoke. Laboratory testing of individuals with severe AAT deficiency in Europe: Liver disease in infancy. Properties of isolated alphaantitrypsin of Pi types M, S and Z. An A1AT deficiency is relatively frequent in children who have hepatic disease of undefined etiology.

Deficifncia analysis was not used in this study since DNA analysis, which is more precise, was possible. The liver in adolescents with alpha 1-antitrypsin deficiency. Table 1 shows the patient’s age at the time of blood collection and the indication used for deciding for subsequent analysis.

A more precise diagnosis requires gene analysis using DNA based techniques 12, 14, The two patients with neonatal cholestasis EKBA and RHBP underwent a liver biopsy when they were 10 weeks and 13 weeks old, respectively, and showed eosinophilic PAS-positive, diastase-resistent globules.

These results suggest that the presence of globules should be investigated using deficencia staining in hepatic fragments obtained before the age of 12 weeks, although a negative result does not eliminate the possibility of A1AT deficiency.
