This study compares and contrasts the clinical features of non-cystic fibrosis bronchiectasis with 3 uncommon disorders known to be associated with bronchiectasis but with distinctly different underlying defined pathophysiologic derangements, namely severe alpha-1 antitrypsin deficiency (AATD), common variable immunodeficiency (CVI) and primary ciliary dyskinesia (PCD).

Name: Chronic obstructive pulmonary diseases (Miami, Fla.)
A female patient was first seen at age 65 due to a diagnosis of alpha-1-antitrypsin deficiency (AATD). She was a lifelong non-smoker, with no significant history of second hand smoke exposure. There w...
Alpha-1 antitrypsin (AAT) is an acute-phase protein with strong inhibitory activity towards proteolytic enzymes, mainly elastase but also trypsin, chymotrypsin and thrombin. The biological role of the...
The most prevalent genetic cause of chronic obstructive pulmonary disease is alpha-1 antitrypsin (A1AT) deficiency, a disorder that has yet to be widely modeled in animals because of species-specific ...
Augmentation therapy with intravenous alpha-1 antitrypsin (AAT) is the only specific therapy for individuals with pulmonary disease from AAT deficiency (AATD). The recommended standard dose (SD; 60 mg...
Gaucher's disease and alpha-1 antitrypsin deficiency are genetic diseases that can cause different kinds of liver damage, but are rarely associated with cirrhosis. Here, we describe the case of a pati...
The purpose of this randomized, double-blind, placebo-controlled study is to evaluate the short-term safety of inhaled recombinant alpha 1-antitrypsin (rAAT) in subjects with alpha 1-antit...
The investigators hypothesize that there is liver injury (inflammation, fibrosis, cirrhosis) in adults with Alpha-1 Antitrypsin Deficiency (AATD), which is asymptomatic, under-recognized, ...
This study will evaluate the safety and efficacy of a recombinant adeno-associated virus vector expressing alpha-1 antitrypsin in patients with alpha-1 antitrypsin deficiency. Three groups...
The purpose of this clinical study is to assess the safety and tolerability of Alpha-1 MP in adult Alpha1-antitrypsin deficient patients.
The aim of this study is to describe the natural history of patients with alpha-1 antitrypsin associated emphysema and to figure out associated prognostic factors.
Deficiency of the protease inhibitor ALPHA 1-ANTITRYPSIN, leading primarily to degradation of elastin of the alveolar walls, as well as other structural proteins of a variety of tissues. (From Scriver, Beaudet, Sly, & Valle, The Metabolic and Molecular Bases of Inherited Disease, 7th ed, p4125)
An autosomal recessive metabolic disorder due to a deficiency in expression of glycogen branching enzyme 1 (alpha-1,4-glucan-6-alpha-glucosyltransferase), resulting in an accumulation of abnormal GLYCOGEN with long outer branches. Clinical features are MUSCLE HYPOTONIA and CIRRHOSIS. Death from liver disease usually occurs before age 2.
A group of disorders which have in common elevations of tyrosine in the blood and urine secondary to an enzyme deficiency. Type I tyrosinemia features episodic weakness, self-mutilation, hepatic necrosis, renal tubular injury, and seizures and is caused by a deficiency of the enzyme fumarylacetoacetase. Type II tyrosinemia features mental retardation, painful corneal ulcers, and keratoses of the palms and plantar surfaces and is caused by a deficiency of the enzyme TYROSINE TRANSAMINASE. Type III tyrosinemia features mental retardation and is caused by a deficiency of the enzyme 4-HYDROXYPHENYLPYRUVATE DIOXYGENASE. (Menkes, Textbook of Child Neurology, 5th ed, pp42-3)
A trypsin-like enzyme of spermatozoa which is not inhibited by alpha 1 antitrypsin.
An inherited urea cycle disorder associated with deficiency of the enzyme ORNITHINE CARBAMOYLTRANSFERASE, transmitted as an X-linked trait and featuring elevations of amino acids and ammonia in the serum. Clinical features, which are more prominent in males, include seizures, behavioral alterations, episodic vomiting, lethargy, and coma. (Menkes, Textbook of Child Neurology, 5th ed, pp49-50)
