Mo1386 Magnitude and Kinetics of Decline in Liver Stiffness After Anti-Viral Therapy in Patients with Chronic Hepatitis C: A Systematic Review and Meta-Analysis

Background & aimsWe performed a systematic review and meta-analysis to estimate the decrease in liver stiffness, measured by vibration-controlled transient elastrography (VCTE), in patients with hepatitis C virus infection who achieved a sustained virologic response (SVR).MethodsWe searched the literature through October 2016 for observational studies or randomized controlled trials of adults with hepatitis C virus infection who received antiviral therapy (either direct-acting antiviral agents or interferon-based therapies), underwent liver stiffness measurement using VCTE before starting therapy, and had at least 1 follow-up VCTE after completion of therapy; studies also provided data on mean or median liver stiffness measurements for patients who did and did not achieve an SVR. We identified 24 studies, and estimated weighted mean difference (and 95% confidence interval) in liver stiffness in patients with versus without SVR using random-effects meta-analysis.ResultsIn patients who achieved SVR, liver stiffness decreased by 2.4 kPa at the end of therapy (95% CI, -1.7 to -3.0), by 3.1 kPa 1-6 months after therapy (95% CI, -1.6 to -4.7), by 3.2 kPa 6-12 months after therapy (90% CI, -2.6 to -3.9), and 4.1 kPa 12 months or more after therapy (95% CI, -3.3 to -4.9) (median decrease, 28.2%; interquartile range, 21.8-34.8). In contrast, there was no significant change in liver stiffness in patients who did not achieve an SVR (at 6-12 months after therapy, decrease of 0.6 kPa; 95% CI, -1.7 to 0.5). Decreases in liver stiffness were significantly greater in patients treated with direct-acting antiviral agents than with interferon-based therapy (decrease of 4.5 kPa vs decrease of 2.6 kPa; P = .03), cirrhosis at baseline (decrease of 5.1 kPa vs decrease of 2.8 kPa in patients with no cirrhosis; P = .02), or high pretreatment levels of alanine aminotransferase (P < .01). Among patients with baseline liver stiffness >9.5 kPa, 47% (95% CI, 27%-68%) achieved posttreatment liver stiffness of <9.5 kPa.ConclusionsIn a systematic review and meta-analysis, we associated eradication of hepatitis C virus infection (SVR) with significant decreases in liver stiffness, particularly in patients with high baseline level of inflammation or patients who received direct-acting antiviral agents. Almost half the patients considered to have advanced fibrosis, based on VCTE, before therapy achieved posttreatment liver stiffness levels <9.5 kPa. Clinical Trial Registration no: CRD42016051034

Treatment of ocular hypertension and open angle glaucoma: meta-analysis of randomised controlled trials

Objective Open angle glaucoma is one of the most common causes of blindness in industrialised nations. Treatments to lower ocular pressure are widely used in glaucoma prevention and treatment, despite conflicting evidence. Design We performed meta-analyses to reassess the effectiveness of pressure lowering treatment to delay the development of glaucoma in ocular hypertension, as well as progression of manifest open angle glaucoma. Data sources Medline, Embase, and the Cochrane Library. Selection of studies Eligible studies were randomised controlled trials with a concurrent untreated control group and information on time to glaucomatous changes to visual field and optic disc. Trial reports were reviewed independently by two investigators in an unblinded standardised manner. Results Meta-analysis of trials in ocular hypertension showed a significant preventive effect of reducing intraocular pressure on progression to glaucoma (hazard ratio 0.56, 95% confidence interval 0.39 to 0.81, P = 0.01; number needed to treat 12). Pooled data of studies in manifest glaucoma showed a significant delay of visual field deterioration (0.65, 0.49 to 0.87, P = 0.003; NNT = 7), with subgroup analysis showing a larger effect in patients with raised pressure and a reduced effect in normal tension glaucoma (subgroup comparison: not significant). Conclusions Lowering intraocular pressure in patients with ocular hypertension or manifest glaucoma is beneficial in reducing the risk of visual field loss in the long term

Clinical Practice Guidelines by the Infectious Diseases Society of America (IDSA): 2020 Guideline on Diagnosis and Management of Babesiosis

The purpose of this guideline is to provide evidence-based guidance for the most effective strategies for the diagnosis and management of babesiosis. The diagnosis and treatment of co-infection with babesiosis and Lyme disease will be addressed in a separate Infectious Diseases Society of America (IDSA), American Academy of Neurology (AAN), and American College of Rheumatology (ACR) guideline [1]. Recommendations for the diagnosis and treatment of human granulocytic anaplasmosis can be found in the recent rickettsial disease guideline developed by the Centers for Disease Control and Prevention [2]. The target audience for the babesiosis guideline includes primary care physicians and specialists caring for this condition, such as infectious diseases specialists, emergency physicians, intensivists, internists, pediatricians, hematologists, and transfusion medicine specialists

Implementing an Antibiotic Stewardship Program: Guidelines by the Infectious Diseases Society of America and the Society for Healthcare Epidemiology of America

Evidence-based guidelines for implementation and measurement of antibiotic stewardship interventions in inpatient populations including long-term care were prepared by a multidisciplinary expert panel of the Infectious Diseases Society of America and the Society for Healthcare Epidemiology of America. The panel included clinicians and investigators representing internal medicine, emergency medicine, microbiology, critical care, surgery, epidemiology, pharmacy, and adult and pediatric infectious diseases specialties. These recommendations address the best approaches for antibiotic stewardship programs to influence the optimal use of antibiotics
