Insights
Diabetes mellitus (DM) significantly increases cirrhosis risk in chronic hepatitis B (CHB) patients. This study found DM is independently associated with higher rates of cirrhosis and potentially hepatocellular carcinoma (HCC) in CHB individuals.
Area of Science:
- Hepatology
- Endocrinology
- Epidemiology
Background:
- Concomitant Diabetes mellitus (DM) is prevalent in chronic hepatitis B (CHB) patients.
- The impact of DM on liver-related outcomes in CHB remains debated.
Purpose of the Study:
- To evaluate the effect of DM on the clinical course, management, and outcomes of CHB patients.
- To investigate the association between DM and the risk of cirrhosis and hepatocellular carcinoma (HCC) in CHB.
Main Methods:
- A large retrospective cohort study using the Leumit Health Service (LHS) database (2000-2019).
- Comparison of two cohorts: CHB with DM (CHD-DM, N.=252) and CHB without DM (N.=964).
- Analysis included clinical parameters, treatment, outcomes, multivariable regression, and Cox regression.
Main Results:
- CHD-DM patients were older, with higher rates of obesity and non-alcoholic fatty liver disease (NAFLD).
- HBeAg seroconversion rates were lower in the CHB-DM group (25% vs. 45.7%).
- DM was independently associated with increased cirrhosis risk (HR 2.63; P=0.002).
Conclusions:
- Concomitant DM is significantly and independently associated with cirrhosis in CHB patients.
- DM may also be associated with an increased risk of HCC in CHB patients, though further research is needed due to limited HCC cases.
Background:
Concomitant Diabetes mellitus (DM) is commonly recognized in patients with chronic hepatitis B (CHB) infection, although its impact on liver-related outcomes remains controversial. We aimed to evaluate the effect of DM on the course, management and outcome of patients with CHB.
Methods:
We performed a large retrospective cohort study utilizing the Leumit-Health-Service (LHS) database. We reviewed electronic reports of 692106 LHS members from different ethnicities and districts in Israel from 2000-2019 and included patients with CHB diagnosis based on ICD-9-CM codes and supportive serology results. These were divided into two cohorts of patients with CHB and DM (CHD-DM) (N.=252) and those with CHB without DM (N.=964). Clinical parameters, treatment figures and patients' outcomes were compared and multiple regression models and Cox regression analysis were performed to investigate the association between DM and cirrhosis/HCC risk in CHB patients.
Results:
CHD-DM patients were significantly older (49.2±10.9 vs. 37.9±14, P<0.001), and had higher rates of obesity (BMI>30) and NAFLD (47.2% vs. 23.1%, and 27% vs. 12.6%, P<0.001, respectively). Both groups had a predominance of inactive carrier (HBeAg negative infection) state, but the HBeAg seroconversion rate was significantly lower in the CHB-DM group (25% vs. 45.7%; P<0.01). Multivariable Cox regression analysis showed that DM was independently associated with increased cirrhosis risk (HR 2.63; P=0.002). Older age, advanced fibrosis and DM were associated with HCC, but DM did not reach significance (HR 1.4; P=0.12) possibly due to the small number of HCC cases.
Conclusions:
Concomitant DM in CHB patients was significantly and independently associated with cirrhosis and possibly with increased risk of HCC.

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,...

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.
