Objective: To evaluate the real-world efficacy and safety of sofosbuvir and velpatasvir (SOF/VEL) tablets in the treatment of Chinese patients with chronic HCV infection. Methods: An open-label, single-center, prospective clinical study was conducted in a county in northern China. A total of 299 cases were enrolled. Of these, 161 cases with chronic hepatitis C and 73 cases with compensated cirrhosis received SOF/VEL for 12 weeks. 65 cases with decompensated cirrhosis received SOF/VEL combined with ribavirin for 12 weeks (22 cases) or SOF/VEL for 24 weeks (43 cases). Virological indicators, liver and renal function indexes, and liver stiffness measurement were detected at baseline, the fourth week of treatment, the end of treatment, and the 12-weeks of follow-up. Adverse reactions and laboratory abnormalities were observed during the course of treatment . The primary endpoint was undetectable rate of HCV RNA (SVR12) at 12 weeks of follow-up with the use of modified intention-to-treat (mITT) approach. Measurement data between two groups were compared using t-test. One Way ANOVA was used for comparison between multiple groups. Enumeration data were analyzed by chi-square test or Fisher's exact test. Results: 291 cases had completed treatment. HCV RNA was undetectable after 12 weeks of follow-up, and the SVR12 rate was 97.3% (95% confidence interval: 95.4%-99.3%). Among them, 97.4% of genotype 1b, 96.4% of genotype 2a, and 100% of those with undetected genotype achieved SVR12. The SVR12 rates in patients with chronic hepatitis C, compensated and decompensated liver cirrhosis were 98.1%, 98.6% and 93.8%, respectively. An improvement in alanine aminotransferase, aspartate aminotransferase and other liver biochemical indicators accompanied with virological clearance and reduced liver stiffness measurement was observed in patients with compensated cirrhosis, with statistically significant difference. There was no significant abnormality in renal function before and after treatment. The most common adverse reactions were fatigue, headache, epigastric discomfort and mild diarrhea. The overall adverse reactions were mild. One patient died of decompensated liver cirrhosis combined with massive upper gastrointestinal bleeding, which was unrelated to antiviral treatment. Four patients discontinued treatment prematurely due to adverse events. Relapse was occurred in four cases, and drug-resistance related mutations were detected in three cases. Conclusion: Sofosbuvir and velpatasvir tablets in Chinese HCV-infected patients with different genotypes, different clinical stages or previously treated with pegylated interferon combined with ribavirin resulted in higher SVR12, indicating that the treatment safety profile is good.

OBJECTIVETo evaluate the efficacy and safety of Qingkailing Injection (, QKL) for treatment of children pneumonia caused by respiratory syncytial virus (RSV).

METHODSRandomized clinical trials (RCTs) comparing QKL with ribavirin injection in the treatment of children pneumonia induced by RSV were searched in PubMed, Science Direct, Cochrane Library, Chinese VIP database, CNKI and Wanfang databases from their inception to March 2014. Meta-analyses were performed using RevMan 5.2 software. The methodological quality of the selected RCTs was evaluated by the Modified Jadad Score. The primary outcome measures were effective rate and the secondary outcomes were relief time of fever and cough.

RESULTSSeven RCTs with 992 cases published from 2008 to 2013 were identified. The meta-analysis results indicated that QKL was more effective in cure rate [risk ratios (RR)=1.32, 95% CI (1.17, 1.50), P<0.01], total effective rate [RR=1.07, 95% CI (1.02, 1.13), P=0.009] and less fever clearance time [mean difference=-0.73, 95% CI (-1.22,-0.23), P=0.004], compared with ribavirin injection in the treatment of RSV-induced children pneumonia. No dead case was reported in all trials. There were 3 trials mentioned adverse events, 2 reported no obvious adverse event occurred while 1 reported adverse events described as skin hypersensitivity, elevation of ALT, a mild abnormal of hepatic and renal function in both QKL and ribavirin group.

CONCLUSIONSQKL was an effective and relatively safe option for the treatment of RSV-induced children pneumonia. These therapeutic effects were promising but need to be interpreted with caution due to variations in the treatment and methodological weakness in the studies.

Chronic hepatitis C virus (HCV) infection is a major cause of liver cirrhosis and hepatocellular carcinoma. Combination therapy of pegylated interferon-alpha (PEG-IFN-α) and ribavirin (RBV) is a current standard treatment for chronic HCV infection in Korea, which has considerable adverse effects. Acute pancreatitis is a rare complication of PEG-IFN-α administration. We report a case of a 62-year-old female who experienced acute pancreatitis after 4 weeks of PEG-IFN-α-2a and RBV combination therapy for chronic HCV infection. The main cause of the acute pancreatitis in this case was probably PEG-IFN-α rather than RBV for several reasons. A few cases have been reported in which acute pancreatitis occurred during treatment with PEG-IFN-α-2b. This is the first report of acute pancreatitis associated with PEG-IFN-α-2a in Korea.

BACKGROUND/AIMS: The previous standard treatment for chronic hepatitis C (CHC) patients, comprising a combination of pegylated interferon (IFN) and ribavirin, was associated with suboptimal efficacy and severe adverse reactions. A new era of direct-acting antivirals is now dawning in Korea. Early experience of applying sofosbuvir-based therapy to CHC patients in Korea is reported herein. METHODS: Data on efficacy and safety were collected for CHC patients treated with a combination of sofosbuvir plus ribavirin or sofosbuvir/ledipasvir with or without ribavirin. RESULTS: This retrospective study included 25 consecutive patients who received sofosbuvir-based therapy (19 with genotype 1b and 6 with genotype 2) at Seoul National University Hospital from May 2014 to April 2015. A virologic response was achieved at week 4 by 85.7% and 80% of the patients with genotypes 1b and 2, respectively. The HCV-RNA level decreased more slowly in IFN-experienced than in treatment-naive patients with genotype 1b. However, the sustained virologic response at week 12 (SVR12) rate did not differ among these patients, and was as high as 100%. The presence of cirrhosis significantly increased the risk of a virologic response failure at week 4 (OR, 11.0; P=0.011) among patients with HCV genotype 1b. Only five patients (20%) experienced minor adverse events, including grade 1 fatigue and headache. The hemoglobin level decreased slightly after sofosbuvir-based therapy, but there was no case of premature discontinuation of this therapy. CONCLUSIONS: In a real clinical practice, sofosbuvir-based therapy for CHC patients in Korea achieved optimal antiviral efficacy with insignificant adverse events. Long-term follow-up data are warranted to ensure the sustained antiviral efficacy and long-term safety of sofosbuvir-based IFN-free therapy.

BACKGROUND/AIMS: Chronic hepatitis C (CHC) is a major comorbidity in patients with hemophilia. However, there are no published data on the efficacy of antiviral therapy in Korea. We assessed the safety and efficacy of combination therapy with peginterferon alpha-2a plus ribavirin for CHC in hemophilia. METHODS: Patients (n=115) were enrolled between March 2007 and December 2008. Seventy-seven patients were genotype 1 or 6, and 38 patients were genotype 2 or 3. We evaluated rapid virologic responses (RVRs), early virologic response (EVRs), end-of-treatment response (ETRs), sustained virologic response (SVRs), and relapses. Safety evaluations included adverse events and laboratory tests. RESULTS: Eleven patients were excluded from the study because they had been treated previously. Among the remaining 104 treatment-naive patients, RVR was achieved in 64 (60.6%), ETR was achieved in 95 (91.3%), and SVR was achieved in 89 (85.6%). Relapse occurred in eight patients (8.9%). Common adverse events were hair loss (56.7%) and headache (51.0%). Common hematologic adverse events were neutropenia (22.1%), anemia (27.9%), and thrombocytopenia (3.8%). However, there were no serious adverse events such as bleeding. RVR was the only predictor of SVR in multivariate analysis. CONCLUSIONS: Peginterferon alpha-2a plus ribavirin combination treatment produced a favorable response rate in CHC patients with hemophilia without serious adverse events.

Various adverse events have been reported during combination therapy with pegylated (PEG)-interferon-alpha and ribavirin, although opportunistic infections, especially cryptococcal meningitis, are very rare. A 61-year-old woman complained of headaches and a fever during treatment of a chronic hepatitis C virus (HCV) infection. She had been treated for 7 months. Her headaches were refractory to analgesics, and she developed subtle nuchal rigidity. The cerebral spinal fluid (CSF) revealed a white blood cell count of 205/mm3, 51 mg/dL protein, 35 mg/dL glucose, and negative Cryptococcus antigen. The CSF culture resulted in no growth. Five days later, the CSF was positive for Cryptococcus antigen. We administered amphotericin B and flucytosine, followed by fluconazole. Approximately 2 months later, she was discharged. For the first time, we report a case of cryptococcal meningitis during the treatment of chronic HCV with PEG-interferon-alpha and ribavirin.

OBJECTIVETo evaluate the efficacy and safety of ribavirin aerosol in children with hand-foot-mouth disease (HFMD).

METHODSA randomized, double-blind, placebo-controlled trial was performed. A total of 119 children with mild HFMD were randomly divided into an observed group (n=59) and a control group (n=60). In the observed group, ribavirin aerosol was given four times within the first hour, followed by once every other hour for the remaining time of the day and day 2; from days 3 to 7, it was given 4 times per day, with 2-3 sprays every time, for 7 days. In the control group, placebo was given in the same way as in the observed group. Additionally, both groups used oral antiviral liquid. The scores of clinical symptoms including oral ulcer, skin rash, nasal congestion, runny nose, sneezing, cough, and fever before and after treatment were recorded to evaluate treatment outcomes. Throat swabs were taken before treatment and 5-7 days after treatment to measure viral load by RT-PCR and to compare the negative conversion rate between the two groups.

RESULTSFifty-seven patients in the observed group and 56 patients in the control group were tested according to the original research design. After 5-7 days of treatment, the observed group had a significantly higher overall negative conversion rate of enterovirus than the control group (P<0.01). The overall marked response rate and overall response rate of the observed group were 89% and 89%, respectively, significantly higher than those of the control group (29% and 43%). During treatment, there were no adverse reactions such as dizziness, vomiting, and notable decreases in hemoglobin, white blood cells, and platelets in the two groups.

CONCLUSIONSRibavirin aerosol can be effectively and safely used for treating mild HFMD. With low dosage and few adverse reactions, it holds promise for clinical application.

OBJECTIVETo analyze the frequency of thyroid dysfunction and determine its influencing factors in chronic hepatitis C (CHC) patients treated with pegylated-interferon alpha (peg-IFNa)-2a and ribavirin (RBV) combination therapy.

METHODSA total of 194 CHC patients were treated with peg-IFNa-2a and RBV for 48 weeks. Development of thyroid dysfunction was recorded. Clinical and biological factors from pre-treatment (baseline) to post-treatment were statistically analyzed to determine correlation with thyroid dysfunction in this patient population.

RESULTSFifty-two (26.80%) of 194 peg-IFNa-2a/RBV-treated patients developed thyroid dysfunction. Dysfunction severity ranged from hyperthyroidism (n = 1, 0.52%) and hypothyroidism (n = 10, 5.15%) to subclinical hyperthyroidism (n = 4, 2.06%) and subclinical hypothyroidism (n = 37, 19.07%). The dysfunction rate was significantly higher after peg-IFNa-2a/RBV treatment (26.80% vs. 12.37% at baseline, x2 = 12.829, P less than 0.05, odds ratio (OR) = 0.386, 95% confidence interval (CI): 0.226-0.657), in females (33.00% vs. 20.21% in males, P less than 0.05, 95% CI: 1.016-3.040), and in thyroid auto-antibody positive patients (64.29% vs. 23.89% in negative patients, P less than 0.05, 95% CI: 1.681-36.183). Early virological response did not have any significant effect on dysfunction rate (23.00% vs. 30.85% no early virological response, x2 = 1.522, P more than 0.05) nor did end of treatment response (27.19% vs. 26.25% no response at end of treatment, x2 = 0.021, P more than 0.05). Patients who developed thyroid dysfunction had higher interleukin (IL)-6 at baseline (i.e. before peg-IFNa-2a/RBV treatment) (27.08+/-14.90 vs. 11.65+/-5.46 in patients who maintained normal thyroid function, t = 3.127, P less than 0.05, 95% CI: 5.28-25.58). IL-6 levels were not significantly different between the two groups at 24 weeks (6.30+/-2.47 vs. 6.81+/-2.80, t = 0.352, P more than 0.05). IL-6 levels before and after 48 weeks of treatment in normal thyroid function patients were 27.08+/-14.90 and 6.30+/-2.47, t = 3.632, P less than 0.05, and in thyroid dysfunction patients were 11.65+/-5.46 and 6.81+/-2.80, t = 1.997, P more than 0.05.

CONCLUSIONPeg-IFNa-2a/RBV combination therapy may cause thyroid dysfunction, especially hypothyroidism, in CHC patients. Female sex and thyroid auto-antibody positivity may put CHC patients at higher risk of developing thyroid dysfunction during peg-IFNa-2a/RBV therapy. Elevated IL-6 may be a predictive marker of peg-IFNa-2a/RBV-induced thyroid dysfunction.
