Alpha-1 antitrypsin deficiency (AATD) liver disease is characterized by marked heterogeneity in presentation and progression, despite a common underlying gene mutation, strongly suggesting the involvement of other genetic and/or epigenetic modifiers. Variation in clinical phenotype has added to the
OBJECTIVE
Nonalcoholic fatty liver disease (NAFLD) is associated with obesity and affects roughly 10% of children. However, NAFLD is often diagnosed by exclusion - that is, obese children with an elevated alanine aminotransferase (ALT) are screened for other liver diseases in the absence of a
OBJECTIVE
Alpha-1 antitrypsin deficiency (AATD) is an uncommonly recognized cause of liver disease in adults, with descriptions of its natural history limited to case series and patient-reported data from disease registries. Liver pathology is limited to selected patients or unavailable. Therefore,
Patients with homozygous protease inhibitor (Pi) type ZZ or a few rare M-like types may develop liver cirrhosis due to intracellular storage of alpha-antitrypsin (AAT), whereas some patients with heterozygous Pi MZ or SZ normally present with transient abnormal liver function tests in childhood. We
By definition bronchiectasis (BE) means destructed structure of normal bronchus as a consequence of frequent bacterial infections and inflammation. In many senses, BE is a neglected orphan disease. A recent pan-European registry study, EMBARC, has been set up in order to better BACKGROUND
The widespread use of routine biochemical assays has led to increased incidental findings of hypertransaminasemia. We aimed to evaluate the prevalence of different causes of raised aminotransferase levels in children referred to a university department of pediatrics.
METHODS
We
BACKGROUND
Our aim was to study liver disorders in asymptomatic patients with slightly to moderately increased liver transaminase values in a population living in an area with a low prevalence of viral and hereditary liver diseases.
METHODS
One hundred and fifty consecutive patients with slightly to
Autophagy is a self-digestion process that plays an important role in the development, differentiation and homeostasis of cells, helping their survival during starvation and hypoxia. Accumulated mutant proteins in the endoplasmic reticulum can be degraded by autophagy in alpha-1 antitrypsin
NAFLD likely is the most common liver disease in children and is responsible for significant progression to cirrhosis, portal hypertension, and the need for liver transplantation in adults and even in some adolescents. Early diagnosis and lifestyle interventions appear to be our best hope for
Seventy-two long-surviving liver transplant recipients were evaluated prospectively, including a baseline allograft biopsy for weaning off of immunosuppression. Thirteen were removed from candidacy because of chronic rejection (n = 4), hepatitis (n = 2), patient anxiety (n = 5), or lack of
Homozygosity for the Pi*Z variant of the gene that encodes the alpha-1 antitrypsin peptide (AAT), called the Pi*ZZ genotype, causes a liver and lung disease called alpha-1 antitrypsin deficiency. Heterozygosity (the Pi*MZ genotype) is a risk factor for cirrhosis in individuals with Autophagy, or cellular self-digestion, is a cellular pathway crucial for development, differentiation, survival, and homeostasis. Its implication in human diseases has been highlighted during the last decade. Recent data show that autophagy is involved in major fields of hepatology. In liver
