529. PROPROTEIN CONVERTASE 6 PLAYS A CRITICAL ROLE IN MODULATING THE HUMAN ENDOMETRIAL EPITHELIUM FOR RECEPTIVITY AND IMPLANTATION
2009
Successful embryo implantation is an important step in establishing pregnancy, requiring a healthy embryo and a receptive endometrium. Establishment of endometrial receptivity involves morphological and physiological changes initially in the endometrial epithelium, but the underlying molecular mechanisms are not fully understood. We have previously demonstrated that proprotein convertase 5/6 (PC6), a member of the proprotein convertase (PC) family, is up-regulated in the endometrium specifically at implantation in association with epithelial differentiation, in the human and monkey. PCs convert a range of precursor proteins of important functions into their bioactive forms; they are thus r…
Factors influencing vaccine uptake in Germany.
2001
While vaccines have virtually eliminated many infectious diseases in Germany, vaccination coverage in children, adolescents and adults is still unsatisfying. This situation is mainly due to inadequate remuneration of vaccination services, structural deficits in the health care system and a lack of motivation. Political support and leadership would most likely be able to change this situation.
Influence of spurious dilution and hyperglycemia on erythrocytes and platelets evaluated with two different hematological analyzers
2015
The integrity of whole blood samples may be compromised by suboptimal collection practices. Therefore, we investigated the influence of spurious hyperglycemia on erythrocytes and platelets, assessed with two hematological analyzers using optical or impedance technique. Three K2EDTA blood specimens were collected from 12 healthy subjects, pooled and divided into four aliquots. The first aliquot was left untreated (glucose concentration 4.4 mmol/L), whereas scalar amounts of standard 5% glucose solution were added to the remaining, generating glucose contamination of 5% (19.2 mmol/L), 10% (33 mmol/L) and 20% (62 mmol/L). Hematological testing was then performed using Siemens Advia 2120 and Sy…
Treatment Persistence and Safety of Apremilast in Psoriasis: Experience With 30 Patients in Routine Clinical Practice
2020
Apremilast is a phosphodiesterase-4 inhibitor taken orally. Little information about its use in routine clinical practice is available. We aimed to assess treatment safety and persistence rates in patients on apremilast for different forms of plaque psoriasis. This observational retrospective study included 30 patients with psoriasis who were treated with apremilast between January 2016 and December 2017 in our hospital. Twelve patients had palmar-plantar psoriasis, 8 had plaque psoriasis mainly on the scalp, and 10 had plaque psoriasis in other locations. The probable period of treatment persistence in patients in the 50th percentile was 18.5 months according to survival analysis of the se…
Tocilizumab therapy for unresponsive pulmonary arterial hypertension in a patient with Takayasu arteritis
2016
A 46-year-old female Caucasian patient was referred to our unit with upper extremity claudication, dyspnoea [New York Heart Association (NYHA) Class III], and weight loss. On physical examination, ...
Arterial thrombosis in Philadelphia-negative myeloproliferative neoplasms predicts second cancer: a case-control study.
2020
Abstract Patients with Philadelphia-negative myeloproliferative neoplasm (MPN) are prone to the development of second cancers, but the factors associated with these events have been poorly explored. In an international nested case-control study, we recruited 647 patients with carcinoma, nonmelanoma skin cancer, hematological second cancer, and melanoma diagnosed concurrently or after MPN diagnosis. Up to 3 control patients without a history of cancer and matched with each case for center, sex, age at MPN diagnosis, date of diagnosis, and MPN disease duration were included (n = 1234). Cases were comparable to controls for MPN type, driver mutations and cardiovascular risk factors. The freque…
Ibrutinib As Treatment for Chemoimmunotherapy-Resistant Patients with Follicular Lymphoma: First Results from the Open-Label, Multicenter, Phase 2 DA…
2016
Abstract Background: While first line therapy for FL with chemotherapy or chemoimmunotherapy produces durable responses, most patients (pts) with FL eventually relapse. Those who become resistant to chemoimmunotherapy have limited treatment options. Ibrutinib, an inhibitor of BTK (Bruton's tyrosine kinase) and ITK (interleukin-2-inducible T-cell kinase), has demonstrated robust clinical activity in various B-cell non-Hodgkin lymphomas. Previous Phase 1 and 2 studies have shown promising results with single-agent ibrutinib in pts with relapsed or refractory FL (Bartlett NL. Blood. 2014; 800 & Fowler N. Blood. 2015; 2706). The aim of the DAWN study was to provide additional efficacy and s…
Efficacy and Safety of Single-Agent Quizartinib (Q), a Potent and Selective FLT3 Inhibitor (FLT3i), in Patients (pts) with FLT3-Internal Tandem Dupli…
2018
Abstract Introduction: FLT3-ITD mutations are among the most common molecular abnormalities in AML, occurring in ≈ 25% of pts. These driver mutations are associated with high leukemic burden and poor prognosis, eg, high risk of relapse, decreased response to salvage therapy, and shorter overall survival (OS). Pts with R/R FLT3-ITD AML have a worse prognosis and represent a population with high unmet medical need. Q is a once-daily, oral, highly potent and selective FLT3i shown in phase 2 trials to have promising single-agent antileukemic activity and a manageable safety profile. QuANTUM-R was the first global, phase 3, randomized controlled trial (NCT02039726) to show that an FLT3i prolonge…
Idiopathic thrombotic thrombocytopenic purpura: strongest risk factor for relapse from remission is having had a relapse
2016
BACKGROUND Thrombotic thrombocytopenic purpura (TTP) is a rare, episodic clinical syndrome involving the production of thrombi in the microvasculature accompanied by thrombocytopenia and symptoms of organ ischemia. Idiopathic TTP develops when a patient produces antibodies that react with the protease ADAMTS13. The course after an episode is unpredictable; patients may relapse frequently or never. There is no laboratory value that can reliably predict potential relapse. STUDY DESIGN AND METHODS To assess diagnostic and predictive values for risk of relapse, plasma samples from 27 patients with idiopathic TTP in remission were analyzed for anti-ADAMTS13 immunoglobulin (Ig)G, ADAMTS13 activit…
Does adiponectin play a role in the pathogenesis of chronic spontaneous urticaria?
2020
Introduction Chronic spontaneous urticaria constitutes an interdisciplinary problem and its pathogenesis is still a subject of debate. Overweight and hyperlipidemia are supposed to be related to chronic spontaneous urticaria. Fatty tissue can be the source of adipokines. Aim of the study To assess the potential role of adiponectin in chronic spontaneous urticaria pathogenesis. Material and methods The study included 52 chronic spontaneous urticaria patients and 43 healthy controls. The patients were divided into two subgroups: patients with wheals only, and patients with urticaria and an accompanying angioedema. The adiponectin concentration was measured in all studied subjects. Results No …
