Sacco University Hospital, Department of Clinical Sciences & Community Health, University of Milan, Milan, Italy VWD is the most common inherited bleeding disorder and is due to a deﬁciency and/or abnormality of VWF. VWD is inherited in an autosomal-dominant or autosomal-recessive pattern, but women are apparently more symptomatic. Three main criteria are required for correct diagnoses of VWD: (1) positive bleeding history since childhood, (2) reduced VWF activity in plasma, and (3) history of bleeding in the family. The bleeding score, together with baseline VWF levels and family history, have been proposed as more evidence-based criteria for VWD. Measurements of a reduced VWF activity in plasma are essential for the diagnosis of VWD; assays for the evaluation of the interactions between VWF and platelet glycoprotein Ib receptor with or without ristocetin, as well as VWF collagen binding, are currently in use. However, other tests such as VWF antigen, factor VIII, ristocetin-induced platelet agglutination, multimeric analysis, VWF propeptide, VWF/FVIII binding assay, and assessment of biological response to desmopres- sin are necessary to characterize VWD types. Levels of VWF activities 30 U/dL have been associated with a bleeding phenotype and the presence of mutations in the VWF gene. Correct Learning Objectives classiﬁcation of different types by clinical and laboratory parameters ● To identify patients at risk for VWD according to their history is important for the management of patients with VWD. The clinical, laboratory, Introduction and molecular parameters useful for VWD diagnosis and classiﬁcation VWD is considered the most common inherited bleeding disorder, are listed in Table 1; the use of these parameters is shown in a ﬂowchart even though its prevalence varies considerably according to the 1-5 (Figure 1). The clinical parameters include both personal and family setting of diagnosis. In population-based studies, prevalence was 6,7 history of bleeding; the presence of other affected members within the estimated to be as high as 0. VWD is due to quantitative and/or qualitative defects of VWF, a multimeric glycoprotein synthesized by endothelial cells and megakaryocytes Clinical parameters that mediates platelet adhesion/aggregation and stabilizes factor Clinical manifestations are excessive mucocutaneous bleeding and VIII (FVIII) in the circulation. In women, menorrhagia caused not only by impaired platelet glycoprotein Ib receptor–VWF may be the only clinical manifestation. Soft tissue and joint bleeding interactions that are usually assessed in plasma in the presence or are rare, except in patients with VWD3, characterized by severe absence of ristocetin (VWF:RCo or VWF:GPIb), but also by deﬁciencies of both VWF and FVIII. The clinical expression of the reduced FVIII levels that often accompany the VWF defect. Although in classical hemophilia, there is VWD1, VWD3, VWD2A, VWD2B, VWD2M, and VWD2N. A plasma VWF level of VWD2A and VWD2B are marked by the absence of high-molecular- 30 IU/dL has been suggested as a threshold to distinguish weight VWF multimers in plasma, but in VWD2B, there is also an patients with a bleeding tendency from healthy subjects with increased afﬁnity of VWF for its platelet receptor, the glycoprotein low-borderline plasma levels of VWF. The identiﬁcation of qualitatively abnormal history is an essential criterion for the diagnosis of inherited variants with decreased platelet-dependent function and a normal bleeding disorders, including VWD. VWD2N shows a full array of based upon bleeding symptoms and calculated using the question- multimers, the defect being in the N-terminal region of the VWF naire proposed by Tosetto et al19 was used to conﬁrm the where the binding domain for FVIII is located. This type is diagnosis in a large cohort of European families with type 1 distinguishable from mild hemophilia A only by the abnormal VWD20; it was subsequently applied with some modiﬁcations to 524 American Society of Hematology Table 1. Clinical and laboratory tests with molecular parameters Among other general diagnostic tools used in the past, the bleeding used for VWD diagnosis time (BT), the original hallmark of the disease, is not always Clinical parameters for VWD prolonged and may be normal in patients with mild forms, such as those with VWD1 and VWD2N.

If higher-level evidence was not available and a gap existed then the authors considered other levels of evidence generic 50 mg sildigra erectile dysfunction treatment los angeles. However purchase 120mg sildigra free shipping beer causes erectile dysfunction, studies that did not provide original data (editorials, letters), were shorter than 4 weeks in duration, did not have an English-language title or abstract, or were published only in abstract form, were excluded. METHODS Literature Search To identify articles relevant to each key question, we searched the Cochrane Central Register of nd Controlled Trials (2 Quarter 2009), MEDLINE (1966-June 4, 2009), PreMEDLINE (through June 4, 2009), and reference lists of review articles (see Appendix B for complete search strategies). Pharmaceutical manufacturers were invited to submit dossiers and citations. For Update 5 we received dossiers from the manufacturers of fluvastatin, rosuvastatin, and the fixed- dose combination products simvastatin/niacin extended release and simvastatin/ezetimibe. All citations were imported into an electronic database (EndNote XI). Study Selection Using the criteria listed above, 2 reviewers independently assessed abstracts of citations identified from literature searches for inclusion. Full-text articles of potentially relevant abstracts were retrieved and a second review for inclusion was conducted by reapplying the inclusion criteria. Statins Page 14 of 128 Final Report Update 5 Drug Effectiveness Review Project Data Abstraction We abstracted the following data from included trials: study design, setting, and population characteristics (including sex, age, ethnicity, and diagnosis); eligibility and exclusion criteria; interventions (dose and duration); comparisons; numbers screened, eligible, enrolled, and lost to follow-up; method of outcome ascertainment; and results for each outcome (nonfatal myocardial infarction), new coronary heart disease (new angina or unstable angina), coronary heart disease mortality, all-cause mortality, stroke or transient ischemic attack, need for revascularization, and percent change from baseline in low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. Since several of the trials grouped some of these events and referred to them as major coronary events, we also included it as a category of cardiovascular health outcomes. We recorded intention-to-treat results if available. Validity Assessment We assessed the internal validity (quality) of trials based on the predefined criteria listed in Appendix C. These criteria are based on those developed by the United States Preventive Services Task Force and the National Health Service Centre for Reviews and Dissemination 10, 11 (UK). For Key Question 3, we rated the internal validity of each trial based on the methods used for randomization, allocation concealment, and blinding; the similarity of compared groups at baseline; maintenance of comparable groups; adequate reporting of dropouts, attrition, crossover, adherence, and contamination; loss to follow-up; and the use of intention-to-treat analysis. Trials that had a fatal flaw in 1 or more categories were rated poor quality; trials meeting all criteria were rated good quality; the remainder were rated fair quality. As the “fair quality” category is broad, studies with this rating vary in their strengths and weaknesses: the results of some fair-quality studies are likely to be valid, while others are only probably valid. A “poor quality” trial is not valid—the results are at least as likely to reflect flaws in the study design as the true difference between the compared drugs. External validity of trials was assessed based on whether the publication adequately described the study population and how similar patients were to the target population in whom the intervention will be applied. We also recorded the funding source and role of the funder. Dosing strategies can also affect applicability of these studies to practice. In fixed-dose studies, we noted whether the doses are used in current practice and compared the rates of side effects when the dosages of the compared statins reduced low-density lipoprotein cholesterol to a similar degree. We noted when the dosages of the compared drugs differed in the extent to which they reduced low-density lipoprotein cholesterol. For studies that titrated doses, we examined whether the methods used to decide when and how much to increase the doses were applied equally to the statins under study. Data Synthesis We constructed evidence tables showing the study characteristics, quality ratings, and results for all included studies. We reported the range of estimates of low-density lipoprotein cholesterol and high-density lipoprotein cholesterol changes for each dosage of each drug. When possible, we also calculated pooled estimates of changes in lipoprotein levels by drug and dosage. We considered the quality of the studies and heterogeneity across studies in study design, patient Statins Page 15 of 128 Final Report Update 5 Drug Effectiveness Review Project population, interventions, and outcomes, in order to determine whether meta-analysis could be meaningfully performed. If meta-analysis could not be performed, we summarized the data qualitatively. In order to quantify the effects of statins on lipid levels, we conducted a meta-analysis of placebo-controlled trials of statins in children with familial hypercholesterolemia. We pooled the mean difference between groups in the change from baseline in low-density lipoprotein cholesterol and high-density lipoprotein cholesterol using a random effects model. We conducted a sensitivity analysis excluding studies rated poor quality. Peer Review and Public Comment Original Drug Effectiveness Review Project reports are independently reviewed and commented upon by 3 to 5 peer reviewers.

Disease-modifying drugs for multiple sclerosis: Single drug addendum: Fingolimod. These organizations selected the topic of the report and had input into its Key Questions. The content and conclusions of the report were entirely determined by the Evidence-based Practice Center researchers. The authors of this report have no financial interest in any company that makes or distributes the products reviewed in this report. MS drugs addendum: fingolimod 5 of 32 Final Original Report Drug Effectiveness Review Project INTRODUCTION In the Drug Effectiveness Review Project Report on Disease-modifying Drugs for Multiple Sclerosis, 5 injectable drugs were reviewed in comparison with each other (most recent update, August 2010). Since that time, an oral medication, fingolimod (Gilenya™) was approved in the United States and Canada for patients with relapsing forms of multiple sclerosis to reduce the frequency of clinical exacerbations and to delay the accumulation of physical disability. Fingolimod is a sphingosine 1-phosphate receptor modulator and is reported to work at least in part though reducing lymphocyte migration into the central nervous system. It is thought to result in redistribution of autoaggressive lymphocytes (T cells and B cells) to the lymph nodes and away from the central nervous system. The purpose of this addendum to the larger report on drugs to treat multiple sclerosis is to review the evidence on the comparative effectiveness and harms of fingolimod compared to the 2 other 5 drugs previously reviewed. Placebo-controlled evidence will be used only where comparative data are not available. A glossary of terms used in Drug Effectiveness Review Project Reports is included in the main report on disease-modifying drugs for multiple sclerosis.
