Renal dysfunction in initially treated patients with chronic hepatitis B: Rate and risk factors

AIM: To investigate the rate of and risk factors for renal dysfunction in initially treated patients with chronic hepatitis B.

METHODS: Patients with chronic hepatitis B treated at our hospital from November 2013 to October 2015 were divided into a chronic hepatitis B group, a compensated liver cirrhosis group, and a decompensated liver cirrhosis group. The simplified Modification of Diet in Renal Disease Study Equation was used to estimate the glomerular filtration rate (e-GFR) to calculate the rate of renal dysfunction [e-GFR < 90 mL/(min•1.73 m²)]. The risk factors for renal dysfunction were analyzed by univariate and multivariate binary logistic regression analyses.

RESULTS: This study collected a total of 358 cases, of which 15.9% had renal dysfunction. The rate of renal dysfunction was 9.5% for the chronic hepatitis B group, 7.9% for the compensated liver cirrhosis group, and 25.2% for the decompensated group (χ² = 16.726, P = 0.000). Multivariate binary logistic regression analysis showed that age, sex, disease progression, and kidney stones were independent risk factors for renal dysfunction.

CONCLUSION: Disease progression is an independent risk factor for abnormal renal function in initially treated patients with chronic hepatitis B. Clinicians should make the best decision based on the specific condition of the patient.
