The specific aims for this study are:
1. To determine if sonographic findings predict the risk of progression of liver disease to cirrhosis by comparing cystic fibrosis subjects with heterogeneous echogenicity pattern on ultrasound to those with normal echogenicity pattern on ultrasound
2. To develop a database and biorepository of serum, plasma, urine and DNA to aid the investigations in ascertaining the mechanisms, consequences, genetic risk factors and biomarkers for the development of cirrhosis
3. To determine if there are differences in health related quality of life, pulmonary or nutritional status in children with cystic fibrosis who have a heterogeneous echo pattern on ultrasound compared to those who have a normal echo pattern on ultrasound
4. To determine if Doppler velocity measurements of hepatic and splenic vessels predict an increased risk for the development of cirrhosis.
For subjects in longitudinal follow up, this study will:
1. Collect detailed clinical and demographic information about each subject at enrollment and during follow up,
2. Obtain and store imaging data from the subject at entry and during follow up,
3. Obtain and store serum, plasma and urine samples from the subject at entry (after matching) and during follow up,
4. Obtain and store DNA from the subject,
5. Obtain and store DNA from the biological parents,
6. Obtain and store quality of life data from the subject and parents at enrollment and during follow up

Staphylococcus aureus (S. aureus) may be related to more rapid progression of cystic fibrosis (CF) lung disease.
An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.
The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.
A chloride channel that regulates secretion in many exocrine tissues. Abnormalities in the CFTR gene have been shown to cause cystic fibrosis. (Hum Genet 1994;93(4):364-8)
A malabsorption condition resulting from greater than 10% reduction in the secretion of pancreatic digestive enzymes (LIPASE; PROTEASES; and AMYLASE) by the EXOCRINE PANCREAS into the DUODENUM. This condition is often associated with CYSTIC FIBROSIS and with chronic PANCREATITIS.
A strain of mice widely studied as a model for cystic fibrosis. These mice are generated from embryonic stem cells in which the CFTR (cystic fibrosis transmembrane conductance regulator) gene is inactivated by gene targeting. As a result, all mice have one copy of this altered gene in all their tissues. Mice homozygous for the disrupted gene exhibit many features common to young cystic fibrosis patients, including failure to thrive, meconium ileus, and alteration of mucous and serous glands.
Hepatology is the study of liver, gallbladder, biliary tree, and pancreas, and diseases associated with them. This includes viral hepatitis, alcohol damage, cirrhosis and cancer. As modern lifestyles change, with alcoholism and cancer becoming more promi...
Affecting over 8,500 people in the UK, Cystic Fibrosis (CF) is one of the UK's most common life-threatening inherited diseases. Around half of the CF population can expect to live over 38 years, although improvements in treatments mean a baby born ...
