Abstract: Objective The aim of this study was to observe the early impact of first-line nucleos(t)ide analogs (NAs), e.g. entecavir(ETV), tenofovir disoproxil fumarate(TDF) and tenofovir alafenamide(TAF), on renal function tests in patients with chronic hepatitis B (CHB). Methods 68 patients with CHB were encountered in our Hospital between September 2019 and May 2021, and out of them, 22 patients received ETV, 26 patients received TDF and 20 patients took TAF therapy. All the patients were followed-up for six months. Serum creatinine (sCr), estimated glomerular filtration rate (eGFR), urine retinol-binding protein (RBP), urine cystatin C (Cys-C), urine N.acetyl.β.D.glucosidase (NAG), urine α1-microglobulin(α1-MG) and urine β2-microglobulin (β2-MG) levels were observed. Results At the end of 24±2 weeks of treatment, serum alanine aminotransferase levels in ETV-treated, TDF-treated and TAF-treated patients were (33.2±5.4)U/L, (31.4±8.2)U/L and (32.7±6.1)U/L (P>0.05), and serum aspartate aminotransferase levels in the three groups were (23.8±7.6)U/L, (24.3±9.2) U/L and (22.9±7.8)U/L, not significantly different among them (P>0.05); serum HBsAg levels in the three groups were (3.0±0.7) lgIU/ml, (2.9±0.5)lgIU/ml and (2.8±0.6)lgIU/ml, and serum HBV DNA loads in the three groups were (1.9±0.6) lgIU/mL, (1.8±0.5) lgIU/mL and (1.6±0.7) lgIU/mL, not significantly different among them (P>0.05); there were no statistically significantly differences as respect to sCr, eGFR, urinary RBP, urinary Cys-C, urinary NAG and urinary β2-MG levels in the three groups (P>0.05), while urine α1-MG level in TDF-treated patients was (1.4±0.9)ln mg/L, significantly higher than (0.7±1.1) ln mg/L in ETV-treated or (0.7±0.9)ln mg/L in TAF-treated patients (P<0.05). Conclusion Our findings suggests that ETV, TDF and TAF have the same antiviral efficacy in patients with CHB, but the renal function tests should be specially surveyed in patients with TDF treatment.
