Association of IL28B Genotypes and Baseline Serum Interferon-γ-Inducible- Protein-10 Levels with Treatment Response in Hepatitis C Virus Patients in China

Changes in renal function indices in cirrhotic chronic hepatitis C patients treated with sofosbuvir-containing regimens

This study aimed to explore changes in hepatic and renal function indices in chronic hepatitis C (CHC) patients treated with direct-acting antivirals (DAAs). Forty-three CHC patients treated with sofosbuvir (SOF)-containing regimens were enrolled. At the end of treatment, the estimated glomerular filtration rate (eGFR) level was significantly decreased and the serum creatinine (Scr) and uric acid (UA) levels were significantly increased compared with baseline levels (eGFR: 86.7 ± 20.4 vs 80.5 ± 21.3, P₀₁ = 0.005; Scr: 83.9 ± 19.1 vs 89.6 ± 21.1, P₀₁ < 0.001; UA: 323.7± 86.2 vs 358.5 ± 93.2, P₀₁ < 0.001); no significant improvements were observed at 24 w post-treatment (eGFR: 86.7 ± 20.4 vs 81.4 ± 18.6, P₀₂ = 0.013; Scr: 83.6 ± 17.9 vs 87.9 ± 18.3, P₀₂ = 0.014; UA: 320.8 ± 76.3 vs 349.3 ± 91.0, P₀₂ = 0.004). When the patients were grouped by liver conditions, non-cirrhotic patients and cirrhotic patients had decreased eGFR levels and increased Scr levels at the end of treatment; at 24 w post-treatment, the eGFR and Scr levels were significantly improved in non-cirrhotic patients (88.4 ± 21.7 vs 83.8 ± 18.5, P₀₂ = 0.142; 84.4 ± 20.4 vs 87.0 ± 16.9, P₀₂ = 0.088), while no obvious improvements were observed in cirrhotic patients (84.3 ± 18.7 vs 78.1 ± 18.6, P₀₂ = 0.002; 83.2 ± 17.7 vs 89.2 ± 20.6, P₀₂ = 0.006). Clinical physicians should closely monitor renal function in patients treated with SOF-containing regimens, especially in cirrhotic patients.

Efficacy and safety of combined directly acting antivirals for treatment of Chinese chronic hepatitis C patients in a real-world setting

AIM

To assess the efficacy and safety of combined directly acting antivirals (DAAs) for the treatment of Chinese chronic hepatitis C (CHC) patients in a real-world setting.

METHODS

Hospitalized CHC patients who were treated with DAAs at Peking University First Hospital between January 2015 and December 2016 were enrolled. Samples and clinical data were collected at 0 wk, 2 wk, 4 wk, 8 wk, 12 wk, or 24 wk during DAAs treatment and at 4 wk, 12 wk, and 24 wk after the end of treatment.

RESULTS

Fifty-four patients who underwent DAAs treatment were included in our study, of whom 83.3% (45/54) achieved rapid virological response at 2 wk after treatment initiation (RVR 2) and 94.4% (51/54) achieved sustained virological response at 24 wk after the end of treatment (SVR 24). Serum creatinine and uric acid levels at the end of treatment were significantly increased compared with baseline levels (83.6 ± 17.9 vs 88.8 ± 19.4, P₀₁ < 0.001; 320.8 ± 76.3 vs 354.5 ± 87.6, P₀₁ < 0.001), and no significant improvements were observed at 24w after the end of treatment (83.6 ± 17.9 vs 86.8 ± 19.1, P₀₂ = 0.039; 320.8 ± 76.3 vs 345.9 ± 89.4, P₀₂ = 0.001). The total frequency of adverse events (AEs) during treatment was 33.3% (18/54), with major AEs being fatigue (16.7%), headache (7.4%), anorexia (7.4%), and insomnia (5.6%).

CONCLUSION

Though based in a small cohort of patients, the abnormal changes in renal function indices and relative high frequency of AEs during combined DAAs treatment should be taken as a note of caution.
