Objective To evaluate the efficacy and safety of antiviral drugs for hepatitis B with YMDD motif variant. Methods We electronically searched MEDLINE (1989-April, 2004), EMBASE (1989-April, 2004), CBMdisc (expand) (1989-April, 2004), and handsearched unpublished Chinese conference proceedings. Randomized and quasi-randomized trials in patients with chronic hepatitis B with YMDD motif variant correlative to lamivudine were collected. Two reviewers extracted the data and assessed the quality of literature independently. The data were then analyzed by RevMan 4.2 software. Results Five studies involving 6 trials and 284 patients were included. According to the results of meta-analysis, antiviral therapy with adefovir plus lamivudine showed significantly better effects on the clearance of serum HBV-DNA and HBeAg and normalization of ALT than that of lamivudine alone (RR 16.61, 95%CI 2.29 to 120.71; RR 6.66, 95%CI 1.23 to 35.88 and RR 6.26, 95%CI 2.29 to 17.12 respectively); also, oxymatrine plus thymothin showed obviously better effects on the clearance of serum HBV-DNA and HBeAg (RR 2.96, 95%CI 1.26 to 6.93 and RR 2.51, 95%CI 1.05 to 5.98 respectively).But adefovir alone showed no better effects on clearance of serum HBV-DNA and HBeAg than that of lamivudine alone (RR 11.00, 95%CI 0.65 to 186.02 and RR 7.00, 95%CI 0.39 to 126.92 respectively); interferon plus lamivudine showed no better effects on the clearance of serum HBV-DNA, HBeAg and the normalization of ALT (RR 3.50, 95%CI 0.90 to 13.58; RR 4.90, 95%CI 0.70 to 35.10 and RR 2.80, 95%CI 0.91 to 8.12 respectively). Chinese herbs plus lamivudine showed no better effects on the clearance of serum HBV-DNA (RR 1.16, 95%CI 0.89 to 1.51). There were no significant side effects in the groups, except flu like symptom in the interferon group, slight kidney impairment in the adefovir group, and aggravation of rare cases in lamivudine group. Conclusions Antiviral therapy with adefovir plus lamivudine, or oxymatrine plus thymothin, shows better effects than with lamivudine alone in terms of antiviral therapy and clinical outcome improvement. However, the evidence is too weak to draw a definite conclusion in this systematic review. Larger sample size and rigorously designed randomized, double blind, placebo control trials are required for future study.
ObjectiveTo analyze the clinical and epidemiological characteristics of hospitalized avian influenza A (H7N9) virus infections in Hunan province from 2013 to 2017, and provide evidences for control, diagnosis and treatment of this disease.MethodsNinety-one hospitalized patients were confirmed with H7N9 infection in Hunan. Excluding 2 patients less than 18 years old and 10 with missing data, 79 patients with H7N9 infection were analyzed.ResultsMost confirmed cases were affected in the second and fifth epidemic wave and number of patients in the fifth wave was more than the sum in prior 4 waves. Epidemiological characteristics, clinical symptoms and case fatality did not change significantly. Administration of antiviral drugs was more active in the fifth wave [from illness onset to antiviral drug: (6.3±2.4)d vs. (7.6±2.4)d, P=0.047]. Multiple logistic regression analysis showed that shock (OR=4.683, 95%CI 1.136–19.301, P=0.033) was the independent risk factor of H7N9 infections. There were no significant differences in case fatality among group oseltamivir, group oseltamivir+peramivir, and group peramivir.ConclusionsPatients with avian influenza A (H7N9) increased in the fifth wave but clinical characteristics changed little. Antiviral treatment should be more active. Shock is an independent risk factor of H7N9 infections. Oseltamivir-peramivir biotherapy can not reduce case fatality compared with oseltamivir or peramivir monotherapy.
ObjectiveAntiviral treatments could benefit chronic hepatitis B (CHB) patients with the regression or improvement of liver fibrosis. However, the degree of dynamic change of liver fibrosis for patients who had not received antiviral treatment remained to be studied. The current study aimed to observe the long-term variation of liver stiffness measurement (LSM), virological and biochemical response on patients without standard antiviral therapy.MethodsA total of 220 patients who were diagnosed with chronic HBV infection, who had not reached the standard of antiviral therapy, and completed a follow-up date of over 2 years in the First Affiliated Hospital of Xi’an Jiaotong University from 2012 to 2018 were retrospectively enrolled. According to the changes of LSM in baseline and follow-up period, the patients were divided into regression group, non-progressive group, and progressive group. The virological and biochemical characteristics of each group were analyzed.ResultsAmong the 220 patients, 153 patients (69.5%) had no progress in LSM degree. Alanine aminotransferase (ALT), HBV DNA, and HBsAg in a few patients increased or slightly decreased, while the vast majority remained in a relatively stable state. 89.5% (137/153) of the non-progressive patients were in grade F0. In addition, 58 patients showed spontaneous improvement with a decreasing rate of 0.460 kPa per year. Patients with ALT of 1-2 ULN had a statistically significant decrease in LSM improvement compared to patients with normal ALT. 82.8% of the LSM-improving patients showed baseline LSM of F1-F3. Only 9 patients showed LSM deterioration, however, which could not be explained by virus replication or necroinflammatory activity. ConclusionsFor patients unsatisfying standard antiviral therapy, most patients with baseline LSM of F0 grade fail to progress, and patients with baseline LSM of F1-F3 show a decrease during follow-up, LSM progression occurs in 4.1% of patients.
ObjectiveTo summarize progress of 25-hydroxycholesterol (25-OHC), 27-hydroxycholesterol(27-OHC), and 7α,25-hydroxycholesterol (7α,25-OHC) three oxidized cholesterols in inflammation and immunology and to provide evidence for related basic researches and diseases treatments.MethodThe relevant literatures about these three important oxidized cholesterols in the inflammation and immunology in recent years were reviewed.ResultsThe 25-OHC and 27-OHC could exert the antiviral effects by interfering with various viruses invading the host via various mechanisms. Moreover, the 25-OHC and 27-OHC also played the important regulatory roles in a variety of inflammatory processes and inflammatory diseases. The 7α,25-OHC played the important role in a variety of inflammatory processes by acting on the inflammatory and immune cell membrane receptor G-protein coupled receptor 183 (also known as Epstein-Barr virus-inducible receptor 2).Conclusion25-OHC, 27-OHC and 7α,25-OHC play an important roles in occurrence and development of various inflammatory and immune responses and diseases of inflammatory and immune by acting on a variety of nuclear receptors and membrane receptors.
Objective
To assess the effect of early antiretroviral therapy on acquired immune deficiency syndrome in Butuo County, Liangshan Autonomous Prefecture.
Methods
A total of 1 037 patients who underwent antiretroviral therapy between January 1st 2012 and December 31st 2013 in Butuo Coungty were divided into 2 groups. The early treatment group (with CD4+ lymphocyte count >350 /mm3) was group A (n=459) and delayed treatment group (with CD4+ lymphocyte count≤350 /mm3) was group B. After 18-month treatment, the treatment retention rate, clinical effect and the side effects of medication in two groups were observed and analyzed.
Results
After 18 months, there were 297 (64.7%) and 320 (55.4%) patients who were persisting in treatment in group A and B, respectively; while the mortality was 6.1% (28/459) and 14.4% (83/578), respectively in group A and B. The differences were significant (P<0.001). The rate of virological suppression in group A and B was 64.0% (190/297) and 63.8% (204/320) respectively without any significant difference (P>0.05). Compared with baseline CD4+ T lymphocyte counts, the growth rate of CD4+ T lymphocyte count in group A and B was 5.7% and 37.5%, respectively; the difference was significant (P<0.001)
Conclusions
Early treatment for acquired immune deficiency syndrome in Butuo County, Liangshan Autonomous Prefecture is effective, however, its growth rate of CD4+ T lymphocyte count is lower than that of delayed treatment. Early treatment doesn’t cause the increasement of the risk of common adverse reactions of medication, and it can reduce the mortality.
ObjectiveTo observe the impact of antiviral therapy on prognosis in patients after curative resection for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC).
MethodsThe data of 50 patients who had undergone liver resection for HBV-related HCC in our department from August 2008 to June 2012 were retrospectively analyzed. The patients were divided into two groups:21 patients who had not antiviral therapy (untreated group) and 29 patients who received antiviral therapy using nucleotide analogues (antiviral therapy group).
ResultsAfter radical resection of HCC, the disease-free survival rate of 1-year, 3-year, and 5-year were 72.4%, 58.6%, and 31.0% in antiviral therapy group and 61.9%, 38.1%, and 14.3% in untreated group, respectively. The overall survival rate of 1-year, 3-year, and 5-year were 86.2%, 68.9%, and 55.2% in antiviral therapy group and 71.4%, 47.6%, and 28.6% in untreated group, respectively. The cumulative disease-free survival rate and overall survival rate of antiviral therapy group were significantly higher than those in the untreated group (P < 0.05). Univariate analysis revealed that the number of tumor, antiviral therapy, and TNM staging were risk factor for tumor-free survival rate, The tumor size, the number of tumor, antiviral therapy, and TNM staging were risk factor for overall survival rate. Multivariate analysis revealed that the number of tumor and TNM staging were independent risk factor for tumor-free survival rate (OR:2.95, 95% CI:1.502-6.114, P < 0.05; OR:4.12, 95% CI:1.972-8.960, P < 0.05), the antiviral therapy and TNM staging were independent risk factor for overall survival rate (OR:3.86, 95% CI:1.745-7.028, P < 0.05; OR:5.17, 95% CI:2.356-11.479, P < 0.05).
ConclusionUsing nucleotide analogs antiviral therapy may improve the prognosis after resection of patients with HBV-related HCC.
