About

Alcohol is a known risk factor for both pancreatitis and cirrhosis. However, not all patients with alcohol related cirrhosis develop pancreatitis. It is not known which patients with alcohol-related cirrhosis develop symptomatic or clinically inapparent pancreatitis (Acute or Chronic Pancreatitis).There is no data whether genetic polymorphisms predispose patients with alcohol-related cirrhosis to additional pancreatic injury. There is no data on the spectrum of clinical and subclinical pancreatic changes (structural and functional) in patients with alcohol-related cirrhosis, and their genotypic correlates.This study aims to determine pancreatitis-related gene variants among patients with alcohol-related cirrhosis, with and without pancreatitis. We also aim to study differences in nutritional and functional parameters among alcoholic cirrhosis with and without chronic pancreatitis and also define the relationship of genetic polymorphisms with the pancreatic phenotype. Consecutive patients with alcohol related cirrhosis will be screened for changes of pancreatitis on CT/MR/EUS. Those with and without pancreatitis will be compared with respect to demographic, clinical, genotype, nutritional status .We will also be including a group of MAFLD/Cryptogenic cirrhosis for genotypic and phenotypic comparison.

Full description

Aim and Objective - To determine pancreatitis-related gene variants among patients with alcohol-related cirrhosis, with and without pancreatitis.

Primary objective: To determine the genetic variants associated with morphological and functional pancreatic changes among patients with alcohol-related cirrhosis.

Secondary objectives

To define the relationship of genetic polymorphisms with the pancreatic phenotype.*
To study differences in nutritional and functional parameters among alcoholic cirrhosis with and without chronic pancreatitis.

Hypothesis -

Genetic polymorphisms related to pancreatitis predispose patients with alcohol-related cirrhosis to additional pancreatic injury.

Associated chronic pancreatitis (clinically apparent or subclinical) negatively influences the nutritional and functional status of patients with alcohol-related cirrhosis

Study design: Cross sectional study of two study cohorts
Study period: 1 year.
Sample size with justification: Studies have reported pathogenic SPINK 1 mutations in 25% -50.0% among idiopathic CP and 10-20% in acute pancreatitis as compared to 1%-4.7% among controls. The investigator assume pathogenic SPINK 1 mutation frequency of 50% and 1% among alcohol-related cirrhosis with and without CP, respectively. The investigator also assume a 33% prevalence of CP among alcohol-related cirrhosis. With significance (α) at 0.5, power of 80%, investigator need to enroll 100 patients of alcohol-related cirrhosis.The investigator will also include a cohort of 50 males with cirrhosis of other etiologies.
