Significantly Decreased Islet β Cell Function is Closely Associated with Hyperglycemia in Chronic Hepatitis B...

Area of Science:

• Endocrinology
• Hepatology
• Metabolic Syndrome

Background:

• Chronic hepatitis B (CHB) is a significant global health concern.
• Understanding glucose metabolism disturbances in CHB is crucial for patient management.
• Islet beta cell function plays a key role in glucose homeostasis.

Purpose of the Study:

• To investigate glucose metabolism and islet beta cell function in CHB patients.
• To identify risk factors associated with impaired glucose metabolism and beta cell function in CHB.
• To compare these parameters between CHB patients and a non-hepatitis B virus (non-HBV) control group.

Main Methods:

• A cross-sectional study involving 110 CHB patients and 110 matched non-HBV controls.
• Assessment of glucose metabolism using fasting plasma glucose (FPG) and 2-hour postprandial plasma glucose (2h-PG).
• Evaluation of islet beta cell function via homeostasis model assessment of beta cell function (HOMA-β) and insulin resistance (HOMA-IR).

Main Results:

• CHB patients exhibited higher FPG and 2h-PG levels, and significantly lower HOMA-β values compared to controls, irrespective of glucose metabolism status.
• Abnormal glucose metabolism was more prevalent in CHB patients with liver cirrhosis or HBeAg-negative status.
• HBeAg-negative status and hepatitis B envelope antibody levels were identified as key risk factors for abnormal glucose metabolism, while HBV markers did not affect HOMA-β.

Conclusions:

• Islet beta cell function is compromised in CHB patients, contributing to hyperglycemia.
• Further research is warranted to confirm these findings and elucidate the mechanisms by which HBV impacts beta cell function.
