Abstract: Objective To investigate the clinical characteristics and risk factors for thyroid disease in patients before and during interferon treatment in viral hepatitis patients. Methods Total of 185 patients with chronic hepatitis B and chronic hepatitis C who received interferon treatments were enrolled. All patients took one year follow-up. Clinical data was analyzed to elucidate the relationship between IFN therapy and thyroid dysfunction. Results The 98 cases of chronic hepatitis B (CHB group) and 87 cases of chronic hepatitis C patients (CHC group) were enrolled. The 27 patients (14.6%) had thyroid dysfunction before IFN treatment. Less male patients (3.5%, 4/115) had thyroid dysfunction before IFN therapy than female patients (32.9%, 23/70). More CHC patients 23.0% (20/87) had thyroid dysfunction before IFN therapy than CHB patients (7.1%, 7/98). And more CHC patients were TPOAb positive before IFN treatment than CHB patients. More female patients (80.0%, 56/70) had thyroid dysfunction during IFN therapy than male patients (16.5%, 19/115). More CHC patients (66.7%, 58/87) had thyroid dysfunction during IFN therapy than CHB patients (17.3%, 17/98). And more CHC patients were TPOAb positive during IFN treatment than CHB patients. Logistic regression indicates that female, chronic hepatitis C and TPOAb positive are independent risk factors for thyroid dysfunction. Conclusions Female CHC patients with TPOAb positive are more likely to have thyroid disease.
