Additional data on hepatic function tests in cystic fibrosis
Insights
This study observed 50 cystic fibrosis (CF) patients for 3 years, finding distinct biochemical patterns in those with cirrhosis. Liver function tests revealed abnormalities, distinguishing cholestatic and cellular cirrhosis types.
Area of Science:
- Hepatology
- Gastroenterology
- Pediatric Medicine
Background:
- Cystic fibrosis (CF) is a genetic disorder affecting multiple organs, including the liver.
- Liver disease, specifically cirrhosis, can be a complication in CF patients.
- Understanding the biochemical profiles of liver complications in CF is crucial for patient management.
Purpose of the Study:
- To investigate liver function and biochemical patterns in cystic fibrosis patients.
- To differentiate between various types of liver cirrhosis in CF patients.
- To assess the prevalence and characteristics of liver abnormalities in CF.
Main Methods:
- Longitudinal observation of 50 cystic fibrosis patients over 3 years.
- Performance of liver function tests assessing cytolysis, cholestasis, and cellular insufficiency.
- Assay of immunoglobulin and prothrombin levels.
- Analysis of IgA:Transferrin ratio and gamma-glutamyl-transpeptidase levels for cirrhosis subtyping.
Main Results:
- Nine out of 50 CF patients developed multilobular cirrhosis, showing generally abnormal liver function tests.
- Two distinct biochemical patterns of cirrhosis were identified: cholestatic and cellular.
- The IgA:Transferrin ratio and gamma-glutamyl-transpeptidase levels were key in distinguishing these patterns.
- In non-cirrhotic CF patients, 50% exhibited temporary increases in cytolysis and cholestasis.
Conclusions:
- Cystic fibrosis patients with cirrhosis exhibit specific biochemical abnormalities.
- Liver cirrhosis in CF can be biochemically classified into cholestatic and cellular types.
- These biochemical distinctions aid in understanding and potentially managing liver complications in CF.
Abstract:
Fifty cystic fibrosis (CF) patients, of whom 9 had multilobular cirrhosis, were observed regularly for a period of 3 years and various liver function tests, indicating cytolysis, cholestasis and cellular insufficiency were performed. Immunoglobulin and prothrombin were assayed. In 9 patients with cirrhosis, the tests were generally abnormal. Two distinct biochemical patterns of cirrhosis were distinguished, one clearly cholestatic and the other of a more cellular type. The distinction was made on the basis of the IgA : Transferrin ratio and of gamma-glutamyl-transpeptidase levels. In the non-cirrhotic patients, a temporary increase of cytolysis and cholestasis was observed in 50% of the cases.
