Diabetes mellitus in chronic active hepatitis and cirrhosis
Insights
Diabetes is highly prevalent in chronic liver disease patients in Saudi Arabia, affecting 44% of severe chronic active hepatitis and 40% of cirrhosis cases. This is linked to long-term insulin resistance in a genetically predisposed population.
Area of Science:
- Hepatology
- Endocrinology
- Metabolic Disorders
Background:
- Chronic liver diseases like hepatitis and cirrhosis are common.
- Diabetes mellitus is a significant global health concern.
- The relationship between chronic liver disease and diabetes requires further investigation.
Purpose of the Study:
- To determine the prevalence and characteristics of glucose intolerance and diabetes in patients with chronic active hepatitis, cirrhosis, chronic persistent hepatitis, and hepatoma.
- To compare the prevalence of diabetes in liver disease patients with the general population and diabetic patients with liver disease.
Main Methods:
- Retrospective review of 293 patients with various liver conditions.
- Analysis of fasting serum glucose levels to diagnose diabetes.
- Assessment of glucose tolerance and insulin resistance.
Main Results:
- Diabetes prevalence was 8% in chronic persistent hepatitis/mild chronic active hepatitis, 44% in severe chronic active hepatitis, 40% in cirrhosis, and 15% in hepatoma.
- Prevalence in liver disease patients (up to 44%) was significantly higher than in other patients (7%).
- Glucose tolerance in chronic active hepatitis and cirrhosis showed basal hyperinsulinemia and insulin resistance.
Conclusions:
- A high prevalence of diabetes exists in patients with chronic active hepatitis and cirrhosis in Saudi Arabia.
- Insulin resistance associated with chronic liver disease, over time, likely contributes to diabetes development in a genetically susceptible population.
- Liver disease patients have a higher diabetes prevalence than diabetic patients have liver disease.
Abstract:
One hundred consecutive patients with nonautoimmune chronic active hepatitis (51% HBsAg-positive), 50 patients with cirrhosis (38% HBsAg-positive), 25 patients with chronic persistent hepatitis, and 118 patients with hepatoma who were seen at this hospital were reviewed to determine the prevalence and characteristics of glucose intolerance and diabetes in these conditions. Diabetes (fasting serum glucose greater than 7.8 mmol/L, 140 mg/dl on two separate occasions) was present in 8% of patients with chronic persistent hepatitis and mild chronic active hepatitis, 44% of patients with severe chronic active hepatitis, 40% of patients with cirrhosis, and 15% of patients with hepatoma, compared with 7% of all other patients aged 35 yr or over, undergoing liver biopsy. Compared with this high prevalence of diabetes in liver disease, only 3% of diabetic patients referred to the hospital diabetic clinic had chronic hepatitis or cirrhosis. Glucose tolerance was similar in chronic active hepatitis and cirrhosis and was characterized initially by basal hyperinsulinemia, normal basal glucose levels but elevated serum glucose following glucose loading, and evidence of insulin resistance. We suggest that the high prevalence of diabetes in chronic active hepatitis and cirrhosis in Saudi Arabia is due to the insulin resistance of chronic liver disease acting over many years in a population with a high genetic predisposition to diabetes.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
