The effect of IDH inhibitors in AML patients.

Description: 12% of patients with AML harbor mutation at Isocitrate dehydrogenase enzyme (IDH).Mutations at these enzymes result in high level of R2 hydroxyglutarate which competes with 2-alpha-hydroxygluterate resulted in DNA and histone hypermethylation. DNA and histone hypermethylation inhibits cell differentiation and promotes leukemic transformation. Ivosidenib and Enasidenib are IDH inhibitors that promotes cell differentiation and showed promising activity in phase1 and 2 trials in relapse/refractory AML patients and in elderly patients who are not candidate for traditional induction regimens. In this systematic review and meta-analysis, we intend to integrate the results of phase1 and 2 trials that looked at the efficacy and the side effects of IDH inhibitor. Therefore,we will have a clearer picture regarding the efficacy and side effect of these medications.

Screening for Hepatitis B Virus Infection in Nonpregnant Adolescents and Adults: A Systematic Review for the U.S. Preventive Services Task Force [Entered Retrospectively]

Description: Background: A 2014 review for the US Preventive Services Task Force (USPSTF) found antiviral therapy for hepatitis B virus (HBV) infection associated with improved intermediate outcomes, although evidence on clinical outcomes was limited. Purpose: To update the 2014 HBV screening review in nonpregnant adolescents and adults to inform the USPSTF. Data Sources: We utilized the 2014 review, searched the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and Ovid MEDLINE (2014 to August 2019); with surveillance through July 24, 2020. Study Selection: Eligible studies included randomized controlled trials (RCTs) and cohort studies on the benefits and harms of screening versus no screening, and the yield of alternative screening strategies; RCTs on the effects of antiviral therapy versus placebo or no therapy and preferred versus nonpreferred therapies on intermediate outcomes, clinical outcomes, and harms; and cohort studies on clinical outcomes and on the association between intermediate outcomes following antiviral therapy and clinical outcomes. Data Extraction: One investigator abstracted data and a second investigator checked data abstraction for accuracy. Two investigators independently assessed study quality using methods developed by the USPSTF. Data Synthesis (Results): Fifty total studies (30 trials and 20 cohort studies) with a total of 94,168 participants were included; of these, 22 were added for this update. No study directly evaluated the effects of screening for HBV infection versus no screening on clinical outcomes, such as mortality, hepatocellular carcinoma, or cirrhosis. Screening strategies that focused on risk factors such as ever having immigrated from high prevalence countries plus demographic and behavioral risk factors would identify nearly all HBV infection cases. In one study (N=21,008), only screening immigrants from high HBV prevalence countries would miss approximately two-thirds of infected persons. Based on 18 trials (N=2,972), antiviral therapy was associated with greater likelihood than placebo or no treatment for achieving intermediate outcomes, such as virologic suppression and hepatitis B e antigen or hepatitis B surface antigen loss or seroconversion; the numbers needed to treat ranged from 2.6 for virological suppression to 17 for hepatitis B e antigen seroconversion. Based on 12 trials (N=4,127), preferred (first-line) antiviral therapies were at least as likely as nonpreferred therapies to achieve intermediate outcomes. Based on 16 trials (N=4,809), antiviral therapy might be associated with improved clinical outcomes, but data were sparse and imprecise. Nine cohort studies (N=3,893) indicated an association between achieving an intermediate outcome following antiviral therapy and improved clinical outcomes, but were heterogeneous (hazards ratios ranged from 0.07 to 0.87). Antiviral therapy was associated with higher risk of withdrawal due to adverse events versus placebo or no antiviral therapy. Limitations: Only English-language articles were included, clinical outcome data for antiviral therapies were limited, observational studies were included on effects of antiviral therapy on long-term clinical outcomes and the association between intermediate and clinical outcomes, and some studies were conducted in countries where the prevalence and natural history of HBV infection are different from the United States. Conclusions: There was no direct evidence for the clinical benefits and harms of HBV screening versus no screening. Antiviral therapy for HBV infection was associated with improved intermediate outcomes and may improve clinical outcomes. Research is needed to clarify effects of screening and subsequent interventions on clinical outcomes and to identify optimal screening strategies.

Acute Treatments for Episodic Migraine in Adults: A Systematic Review and Meta-Analysis

Description: Objectives. To evaluate the effectiveness and comparative effectiveness of pharmacologic and non-pharmacologic therapies for the acute treatment of episodic migraine in adults. Data source. MEDLINE, Embase, Cochrane Central Registrar of Controlled Trials, Cochrane Database of Systematic Reviews, PsycINFO, Scopus and various grey literature sources from database inception to April 24, 2020. Comparative effectiveness evidence about triptans and nonsteroidal anti-inflammatory drugs (NSAIDs) were extracted from existing systematic reviews. Review methods. We included randomized controlled trials (RCTs) and comparative observational studies that enrolled adults who received an intervention to acutely treat episodic migraine. Pairs of independent reviewers selected and appraised studies. Results. Data on triptans were derived from 186 RCTs summarized in 9 systematic reviews (101,276 patients, most studied was sumatriptan, followed by zolmitriptan, eletriptan, naratriptan, almotriptan, rizatriptan, and frovatriptan). Compared with placebo, triptans resolved pain at 2 hours and 1 day, and increased the risk of mild and transient adverse events (high strength of the body of evidence [SOE]). Data on NSAIDs were derived from 5 systematic reviews (13,214 patients, most studied was ibuprofen, followed by diclofenac and ketorolac). Compared with placebo, NSAIDs probably resolved pain at 2 hours and 1 day, and increased the risk of mild and transient adverse events (moderate SOE). For other interventions, we included 135 RCTs and 6 comparative observational studies (37,653patients). Compared with placebo, antiemetics (low SOE), dihydroergotamine (moderate to high SOE), ergotamine plus caffeine (moderate SOE) and acetaminophen (moderate SOE) reduced acute pain. Opioids were evaluated in 15 studies (2,208 patients). Tramadol in combination with acetaminophen, butorphanol, meperidine, morphine and hydromorphone may reduce pain at 2 hours and 1 day, compared with placebo (low SOE). Some opioids may be less effective than some antiemetics or dexamethasone (low SOE). No studies evaluated instruments for predicting risk of opioid misuse, opioid use disorder or overdose, or evaluated risk mitigation strategies to be used when prescribing opioids for the acute treatment of episodic migraine. Calcitonin gene-related peptide (CGRP) receptor antagonists improved headache relief at 2 hours and increased the likelihood of being headache-free at 2 hours, at 1 day, and at 1 week (low to high SOE). Lasmiditan (the first approved 5-HT1F receptor agonist) restored function at 2 hours and resolved pain at 2 hours, 1 day, and 1 week (moderate to high SOE). Sparse and low SOE suggested possible effectiveness of dexamethasone, dipyrone, flunarazine, magnesium sulfate, octreotide, tezampanel, and tonabersat. Compared with placebo, several non-pharmacologic treatments may improve various measures of pain, including remote electrical neuromodulation (moderate SOE), magnetic stimulation (low SOE), acupuncture (low SOE), chamomile oil (low SOE), external trigeminal nerve stimulation (low SOE), and eye movement desensitization re-processing (low SOE). However, these interventions, including the noninvasive neuromodulation devices, have only been evaluated by single or very few trials. Conclusions. A number of acute treatments for episodic migraine exist with varying degrees of evidence for effectiveness and harms. Use of triptans, NSAIDs, antiemetics, dihydroergotamine, CGRP antagonists, and lasmiditan is associated with improved pain and function. The evidence base for many other interventions for acute treatment, including opioids, remains limited.
