ObjectivesTo systematically review the methods of pharmacoeconomic evaluation model for hepatitis C therapies and to identify shortcomings of the existing modeling research by comparing the model structure, hypothesis and methodological differences, and to provide suggestions for the construction of high-quality hepatitis C pharmacoeconomic evaluation models.MethodsPubMed, EMbase, The Cochrane Library, CNKI and WanFang Data databases were electronically searched to collect relevant literatures on the pharmacoeconomic evaluation models for hepatitis C therapies from August 2014 to August 2019. Two reviewers independently screened literature, extracted data, and evaluated the quality of the included studies. Then, the data related to the model structure, methods, and assumptions were compared and summarized.ResultsMost of the 46 studies that finally included used similar modeling methods. Ignoring different modeling elements would cause overestimation or underestimation of the value of hepatitis C therapies. Model structure of all studies were similar and key parameters were from the same source. Forty-five studies measured the cost of drugs and medical cost of health status. All studies used quality-adjusted life years as the outcome and reported incremental cost-effectiveness ratio. Thirty studies conducted one-way sensitivity analysis and probability sensitivity analysis.ConclusionsThe included studies share similar methodological designs and have high quality in general. However, there are some differences and deficiencies in research perspective, model types, model assumptions and model verification. Future pharmacoeconomic evaluation model of hepatitis C therapies should report the results of the whole society, establish dynamic model to consider the impact of transmission, make half-cycle correction for long periods, consider the recurrence after cure, model liver transplantation, and verify the model.
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.
At present, the most commonly used nucleoside (acid) anaog (NAs) treatment regimen in clinical practice cannot completely cure chronic viral hepatitis B (CHB). However, although the polyethylene glycol interferon treatment regimen is superior to the NAs regimen in terms of immune mechanism, it has the disadvantage of low hepatitis B virus DNA response rate. In recent years, the cure of CHB is being studied all over the world. Various mechanisms and drug targets are being explored, and diversified therapeutic strategies are also being used. Clinical cure of hepatitis B is possible, but it is still in the early stage, and many potential drugs and better therapeutic strategies are still being tested. This article mainly reviews the latest progress in the treatment of CHB based on the recent research achievements in direct antiviral drugs and host immunotherapy as well as the research progress in combination therapy.
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.
Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic at the end of December 2019, more than 85% of the population in China has been infected. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mainly affects the respiratory system, especially the lungs. The mortality rate of patients with severe infection is high. A percentage of 6% to 10% of patients will eventually develop into COVID-related acute respiratory distress syndrome (CARDS), which requires mechanical ventilation and extracorporeal membrane oxygenation (ECMO) support. Some patients who survive acute lung injury will subsequently develop post COVID-19 pulmonary fibrosis (PCPF). Both fully treated CARDS and severe PCPF are suitable candidates for lung transplantation. Due to the special course, evaluation strategies are different from those used in patients with common end-stage lung disease. After lung transplantation in COVID-19 patients, special treatment is required, including standardized nucleic acid testing for the novel coronavirus, adjustment strategy of immunosuppressive drugs, and rational use of antiviral drugs, which is a big challenge for the postoperative management of lung transplantation. This consensus was evidence-based written and was reached by experts after multiple rounds of discussions, providing reference for assessment and postoperative management of patients with interstitial pneumonia after COVID-19 infection.
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.
目的 通過分析影響四川地區慢性乙型肝炎患者抗病毒治療依從性的因素，探討提高患者治療依從性的策略。 方法 選擇2011年4月－2012年4月在四川大學華西醫院接受核苷（酸）類似物抗病毒治療的324例慢性乙型肝炎患者作為研究對象。采用問卷調查的方法，對患者一般情況、心理狀態、文化程度、經濟情況、疾病認知情況、抗病毒療效、服藥持續性等相關因素進行分析，評估這些因素對患者治療依從性的影響。 結果 324例患者中能夠完全遵照醫囑者78例（24.07%），不能完全依從者246例（75.93%）。心理狀態良好者132例（40.74%），其中依從性良好者54例；心理負擔較重者192例（59.26%），其中依從性良好者24例。初中及以上學歷204例（62.96%），依從性良好者72例；初中以下學歷者120例（37.04%），依從性良好者僅6例。不同心理狀態、文化程度的患者依從率差異有統計學意義。患者經濟狀況、年齡差異對于依從性也有一定影響。 結論 慢性乙型肝炎患者對抗病毒治療的依從性與心理狀態、文化程度者及經濟狀況密切相關。改善患者醫療費用償付能力，對患者進行疾病認知教育以及減少社會歧視等措施有助于提高患者治療依從性。
ObjectivesTo assess the efficacy and safety of corticosteroid and antiviral agents for idiopathic facial nerve paralysis (IFNP) by network meta-analysis.MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI, WangFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) of corticosteroid and antiviral agents for IFNP from inception to January 31th, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. The meta-analysis was performed by R 3.3.3 and Stata 13.0 software.ResultsA total of 16 RCTs involving 3 061 patients were included. The results of network meta-analysis showed that: for the facial function recovery rates, corticosteroid plus antiviral agents was superior to placebo and antiviral agents alone at 3-month follow-up. Corticosteroid plus antiviral agents was superior to placebo, antiviral agents or corticosteroid alone at 6-month follow-up (if the satisfactory recovery was defined as a House-Brackmann grade class Ⅱ or below). When the follow-up exceeded 6 months, corticosteroid alone was superior to placebo and antiviral agents alone, corticosteroid plus antiviral agents was superior to placebo and antiviral agents alone. All of the differences above were statistically significant. For the sequelae, corticosteroid plus antiviral agents and corticosteroid alone were superior to placebo and antiviral agents alone. Corticosteroid plus antiviral agents was superior to corticosteroid alone. The differences were statistically significant. For the adverse events, there were no significant differences between any other pairwise comparisons of these different interventions.ConclusionConsidering the efficacy and safety, patients with IFNP treated corticosteroid plus antiviral agents are more likely to have a better recovery of facial function and less likely to develop sequelae, followed by corticosteroid alone. More high-quality, large scaled and multicenter RCTs are required to verify the conclusions above, and focus on the treatment of children and patients with severe facial paralysis.
