What is the comparative effectiveness of different proton pump inhibitors in eradicating Helicobacter pylori infection? Is there evidence that a particular treatment strategy is more effective or safer than another (for example 400mg hoodia amex, stepping down to a lower dose cheap 400mg hoodia with mastercard, treatment as needed compared with daily treatment cheap hoodia 400mg visa, high dose compared with standard dose safe hoodia 400mg, or switching to an H2 antagonist) for treatment longer than 8 weeks in patients with gastroesophageal reflux disease or ulcer? What are the comparative safety and adverse events of different proton pump inhibitors in patients being treated for symptoms of gastroesophageal reflux disease cheap hoodia 400mg with mastercard, peptic ulcer buy hoodia 400 mg on line, and nonsteroidal anti-inflammatory drug-induced ulcer? Are there subgroups of patients based on demographics, other medications, or comorbidities (including nasogastric tubes and inability to swallow solid oral medication) for which a particular proton pump inhibitor or preparation is more effective or associated with fewer adverse effects? Proton pump inhibitors Page 10 of 121 Final Report Update 5 Drug Effectiveness Review Project METHODS Literature Search To identify articles relevant to each key question, we searched the Cochrane Library (4th Quarter 2008), Medline (1966- week 2 of November 2008), Embase (1980-3rd Quarter 2004), and reference lists of review articles. In electronic searches, we combined terms for gastroesophageal reflux and peptic ulcer with terms for proton pump inhibitors and particular research designs. All citations were imported into an electronic database (EndNote X1). Update 5 added a key question (Key Question 5) addressing different treatment strategies. To identify citations relevant to the new question but published before the literature search for this update, we searched the EndNote library of citations from all previous versions of this report, looking for citations that met criteria for this new question. Study Selection The abstracts of all citations identified in literature searches and dossiers were assessed for inclusion using the predetermined criteria specified in the key questions. For abstracts that met these criteria, full-text articles were retrieved and inclusion criteria reapplied. Citation and full- text review were conducted by one reviewer and checked by a second. We included English-language reports of randomized controlled trials of at least 4 weeks’ duration in adult outpatients with symptoms of gastroesophageal reflux, peptic ulcer, or nonsteroidal anti-inflammatory drug-induced ulcer. Included interventions were a proton pump inhibitor (omeprazole, lansoprazole, pantoprazole, rabeprazole, or esomeprazole) compared with proton pump inhibitor, other ulcer drug (H2 receptor antagonist, prokinetic agent, or antacid), placebo, surgery, or antibiotics. For adverse effects, we also included observational studies. Outcomes measured were symptoms, functional outcomes, endoscopic healing, eradication of Helicobacter pylori, quality of life, and adverse effects. We excluded reports that were published as only abstracts (see Appendix C). To evaluate efficacy we included only randomized controlled trials. The validity of controlled trials depends on how they are designed. Randomized, properly blinded clinical trials 1-3 are considered the highest level of evidence for assessing efficacy. Clinical trials that are not randomized or blinded, and those that have other methodological flaws, are less reliable but are also discussed in our report. Trials that compared one proton pump inhibitor with another provided direct evidence of comparative efficacy and adverse event rates. We did not examine in detail placebo-controlled or active-control trials when head-to-head trials were available. In theory, trials that compare proton pump inhibitors with H2 receptor antagonists or placebos also can provide evidence about efficacy. However, the efficacy of proton pump inhibitors in different trials can be difficult to interpret because of differences between patients. To supplement our analyses of published results, we requested and received from the trial 4, 5 6 funders additional data for 2 published trials and 1 trial that was submitted to the US Food and Drug Administration but not published. Proton pump inhibitors Page 11 of 121 Final Report Update 5 Drug Effectiveness Review Project To evaluate adverse events, we included clinical trials and observational cohort studies. Clinical trials are often not designed to assess adverse events and may select only low-risk patients (in order to minimize drop-out rate) or use inadequately rigorous methodology for assessing adverse events.

Schlenk1 and Hartmut Do¨ hner1 1Department of Internal Medicine III, University Hospital Ulm, Ulm, Germany In recent years, research in genomics has resulted in the rapid uncovering of the molecular pathogenesis of acute myeloid leukemia (AML). The identiﬁcation of the genetic determinants of response to standard—but also to experimental—treatment is increasingly used for patient counseling, to guide clinical decision making, and for resource-efﬁcient care provision at diagnosis, during consolidation treatment and follow-up, and after relapse. Gene mutations now allow us to explore the enormous diversity among cytogenetically deﬁned subsets of AML, in particular the large subset of cytogenetically normal AML. Nonetheless, there are several challenges in evaluating the prognostic value of a speciﬁc mutation in the concert of the various concurrent mutations and determining the relative prognostic value of the genetic proﬁle during the disease course. In particular, changes in the genetic proﬁle in relapse compared with that at diagnosis will increasingly affect the treatment strategy at relapse, but also will give us the possibility of learning which treatment strategy during frontline therapy is best to prevent them. Introduction though the value of PRT in the older patients continues to be Acute myeloid leukemia (AML) is a genetically very heterogeneous debated, in younger patients, the choice for consolidation is based disorder with an incidence of 3 to 4 per 100 000 men and women per on genetic and molecular features and can range from high-dose year.

The multiple treatments form a network of treatment comparisons buy 400mg hoodia amex. Also called multiple treatment comparisons buy 400 mg hoodia mastercard, network analysis hoodia 400 mg on-line, or umbrella reviews order 400mg hoodia with amex. Monotherapy: the use of a single drug to treat a particular disorder or disease buy 400mg hoodia visa. Multivariate analysis: Measuring the impact of more than one variable at a time while analyzing a set of data purchase hoodia 400mg line. N-of-1 trial: A randomized trial in an individual to determine the optimum treatment for that individual. Noninferiority trial: A trial designed to determine whether the effect of a new treatment is not worse than a standard treatment by more than a prespecified amount. Nonrandomized study: Any study estimating the effectiveness (harm or benefit) of an intervention that does not use randomization to allocate patients to comparison groups. There are many types of nonrandomized studies, including cohort studies, case-control studies, and before- after studies. Null hypothesis: The statistical hypothesis that one variable (for example, treatment to which a participant was allocated) has no association with another variable or set of variables. Number needed to harm: The number of people who would need to be treated over a specific period of time before one bad outcome of the treatment will occur. The number needed to harm (NNH) for a treatment can be known only if clinical trials of the treatment have been performed. Number needed to treat: An estimate of how many persons need to receive a treatment before one person would experience a beneficial outcome. Observational study: A type of nonrandomized study in which the investigators do not seek to intervene, instead simply observing the course of events. Odds ratio: The ratio of the odds of an event in one group to the odds of an event in another group. Off-label use: When a drug or device is prescribed outside its specific FDA-approved indication, to treat a condition or disease for which it is not specifically licensed. Outcome: The result of care and treatment and/ or rehabilitation. In other words, the change in health, functional ability, symptoms or situation of a person, which can be used to measure the Atypical antipsychotic drugs Page 211 of 230 Final Report Update 3 Drug Effectiveness Review Project effectiveness of care/treatment/rehabilitation. Researchers should decide what outcomes to measure before a study begins; outcomes are then assessed at the end of the study. Outcome measure: Is the way in which an outcome is evaluated---the device (scale) used for measuring. One-tailed test (one-sided test): A hypothesis test in which the values that reject the null hypothesis are located entirely in one tail of the probability distribution. For example, testing whether one treatment is better than another (rather than testing whether one treatment is either better or worse than another). Open-label trial: A clinical trial in which the investigator and participant are aware which intervention is being used for which participant (that is, not blinded). Random allocation may or may not be used in open-label trials. Per protocol: The subset of participants from a randomized controlled trial who complied with the protocol sufficiently to ensure that their data would be likely to exhibit the effect of treatment. Per protocol analyses are sometimes misidentified in published trials as intention-to- treat analyses. Pharmacokinetics: the characteristic interactions of a drug and the body in terms of its absorption, distribution, metabolism, and excretion. Placebo: An inactive substance commonly called a "sugar pill.
