The success of inherited platelet disorder research is underpinned by broader advances in methodology through the biochemical and molecular revolution of the 20th and 21st centuries, respectively. Recently, modern genomics techniques have affected platelet and platelet disorders research, allowing for the discovery of several genes involved in platelet production and function and for a deeper understanding of the RNA and miRNA networks that govern platelet function. In this short review, we focus on recent developments in the genetic elucidation of several disorders of platelet number and in the molecular architecture that determines the “genetic makeup” of a platelet in health and disease.

Nearly 100 years ago, Eduard Glanzmann, a Swiss pediatrician, ﬁrst characterized a novel hereditary form of mucocutaneous bleeding,1 Classiﬁcation likely representing the ﬁrst detailed scientiﬁc report of an inherited Congenital platelet disorders are usually classiﬁed by platelet platelet disorder. In 1918, just 2 years into his own practice, phenotypic parameters that often include morphology and size as Glanzmann coined the term “thrombasthenie” (weak platelets) to well as mode of inheritance. This is particularly useful for the describe this malady with normal platelet count and morphology yet practicing hematologist when a diagnosis of a hereditary platelet grossly abnormal clot retraction.

For children and adults with type 2 diabetes does sitagliptin differ in efficacy, effectiveness, or harms in achieving glycemic control as monotherapy compared with other hypoglycemic agents or when added as part of combined therapy? Are there subgroups of patients for which sitagliptin is more or less suitable than other hypoglycemic agents? When in October 2007 Pfizer announced that it would no longer provide the inhaled powder for use, the medication was removed from these key questions. According to Pfizer, the decision to remove Exubera was voluntary and was not based on safety or efficacy problems but on lack of demand for the drug. Diabetes Page 9 of 99 Final Report Drug Effectiveness Review Project METHODS Literature Search To identify relevant citations we searched Ovid MEDLINE , Ovid MEDLINE IN-Process (1950 to April Week 3, 2008), Cochrane Database of Systematic Reviews , Cochrane Central rd Register of Controlled Trials , and the Database of Abstracts of Reviews of Effects (3 quarter 2007) using search terms for included drugs, indications, and study designs. Electronic database searches were supplemented by hand searches of reference lists of included studies and reviews. In addition, we searched the US Food and Drug Administration (FDA) Center for Drug Evaluation and Research, the Canadian Agency for Drugs and Technologies in Health, and the National Institute for Health and Clinical Excellence web sites for medical or statistical reviews and technology assessments. Finally, we searched dossiers of published and unpublished studies submitted by pharmaceutical companies. Study Eligibility All citations were reviewed for inclusion using the criteria shown in Table 2. Two reviewers independently assessed titles and abstracts of citations identified from literature searches. Full- text articles of potentially relevant citations were retrieved and assessed for inclusion by two reviewers, and disagreements were resolved by consensus. Results published only in abstract form (such as a conference proceeding) were not included, because they typically provided insufficient detail for adequate quality assessment. Study inclusion and exclusion criteria Included populations • Adults and children • Type 1 and type 2 diabetes mellitus Excluded populations • Gestational diabetes and Type 1 and type 2 diabetes mellitus in pregnancy Subgroups of interest • Demographic characteristics (age, race, and sex) • Concomitant medications and drug-drug interactions • Comorbidities such as obesity and cardiovascular disease • History of hypoglycemic episodes • Baseline A1c • Drug specific-subgroups: pramlintide, renal insufficiency; exenatide, renal insufficiency; and sitagliptin, renal and hepatic insufficiency Included health outcomes • All-cause mortality • Microvascular disease: chronic kidney disease including renal dialysis, renal transplantation, and end-stage renal disease; retinopathy including proliferative retinopathy and blindness; and peripheral neuropathy • Macrovascular disease: cardiovascular events, cardiovascular mortality, stroke or transient ischemic attack, coronary heart disease, cardiovascular procedures, and extremity amputation • Other complications of diabetes: lower extremity ulcers • Quality of life including treatment satisfaction Diabetes Page 10 of 99 Final Report Drug Effectiveness Review Project • Other: hospitalization and medical visits related to diabetes care Included intermediate outcomes • Glycemic control: fasting glucose, post-prandial glucose, and A1c • Change in weight • Time to treatment failure Included safety and harms outcomes • Overall adverse events • Withdrawals due to adverse events • Major adverse events including but not limited to diabetic ketoacidosis and non-ketotic hyperosmolar coma • Specific adverse events including but not limited to hypoglycemia, liver toxicity, liver function abnormalities, gastrointestinal effects, adverse changes in lipid concentrations, and weight gain • Adverse events specific to drug class: DPP-4 inhibitors, infection and neoplasm including cancer; amylinomimetics, neoplasm including cancer Included study designs • All studies (efficacy, effectiveness, and harms) were required to have ≥12 weeks of follow-up, the minimum study duration needed to adequately assess change in glycemic control. We recorded intention-to-treat results when reported. For included systematic reviews, we abstracted the searched databases, study eligibility criteria, numbers of studies and patients represented, characteristics of included studies, data synthesis methods, and main efficacy and safety results. Validity Assessment We assessed the internal validity (quality) of trials based on the predefined criteria listed in Appendix C. These criteria are based on the US Preventive Services Task Force and the National 4, 5 Health Service Centre for Reviews and Dissemination (UK) criteria. 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. We considered methods to meet criteria for intention-to-treat analysis if outcomes for at least 95% of participants were analyzed according to the group to which they were originally assigned. We considered total attrition of ≥15% in any of the treatment arms to be excessive. Diabetes Page 11 of 99 Final Report Drug Effectiveness Review Project Trials that had fatal flaws were rated poor quality. Trials that met all criteria were rated good quality and the remainder 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. A fatal flaw is reflected by failing to meet combinations of items of the quality assessment checklist that work together to suggest a potential for bias. We assessed the quality of systematic reviews using pre-defined criteria developed by Oxman and Guyatt (See Appendix C). These included adequacy of literature search and study selection methods, methods of assessing validity of included trials, methods used to combine studies, and validity of conclusions. Data Synthesis A qualitative analysis of the available evidence or lack of evidence was undertaken. We constructed evidence tables (included as a separate document) showing the study characteristics, quality rating, and results for all included studies. Pooled estimates of effect sizes were estimated by meta-analysis using random-effects 6 models. Results from each study were stratified by dose level of the drug intervention arms (high and low doses). Weighted mean differences between drug and control were calculated for outcomes (percent change in A1c, weight loss, fasting plasma glucose, and post-prandial glucose). Risk ratios between drug and control were pooled for withdrawals and adverse events. Forest plots for both weighted mean difference and risk ratio were created to visually inspect the 7 2 data. The Q-statistic and the I statistic (the proportion of variation in study estimates due to 8, heterogeneity) were calculated to assess heterogeneity between the effects from pooled studies.
