Platelet-Derived GARP Induces Peripheral Regulatory T Cells—Potential Impact on T Cell Suppression in Patients with Melanoma-Associated Thrombocytosis
2020
Platelets have been recently described as an important component of the innate and adaptive immunity through their interaction with immune cells. However, information on the platelet&ndash
Clinical Features And Course Of Refractory Anemia With Ring Sideroblasts Associated With Marked Thrombocytosis
2012
Background Refractory anemia with ring sideroblasts associated with marked thrombocytosis was proposed as a provisional entity in the 2001 World Health Organization classification of myeloid neoplasms and also in the 2008 version, but its existence as a single entity is contested. We wish to define the clinical features of this rare myelodysplastic/myeloproliferative neoplasm and to compare its clinical outcome with that of refractory anemia with ring sideroblasts and essential thrombocythemia. Design and Methods We conducted a collaborative retrospective study across Europe. Our database included 200 patients diagnosed with refractory anemia with ring sideroblasts and marked thrombocytosis…
Lack of efficacy of recombinant human interleukin-6 in patients with advanced renal cell cancer: results of a phase II study.
1998
The present phase II study was undertaken to assess antitumoral activity, safety and tolerability of recombinant human interleukin-6 (rh IL-6) in patients with advanced renal cell cancer. Rh IL-6 was administered as a daily subcutaneous injection at a fixed dose of 150 micrograms/day for a maximum of 42 consecutive days. 12 patients with metastatic renal cell cancer without previous immunotherapy were enrolled and were evaluated for response. No objective clinical responses were observed in the trial. Toxicity was moderate and reversible and mainly comprised fever, influenza-like symptoms, fatigue and moderate hepatotoxicity. Anaemia, leucocytosis, thrombocytosis and induction of an acute p…

Mediterranean Diet Maintained Platelet Count within a Healthy Range and Decreased Thrombocytopenia-Related Mortality Risk: A Randomized Controlled Tr…
2021
There is little information on the dietary modulation of thrombosis-related risk factors such as platelet count. We aimed to assess the effects of Mediterranean diet (MedDiet) on platelet count and related outcomes in an older population at high cardiovascular risk. In participants of the PREDIMED (PREvención con DIeta MEDiterránea) study, we assessed whether an intervention with a MedDiet enriched with extra-virgin olive oil or nuts, relative to a low-fat control diet, modulated platelet count (n = 4189), the risk of developing thrombocytosis and thrombocytopenia (n = 3086), and the association between these alterations and all-cause mortality (median follow-up time: 3.0 years). Although p…
A retrospective analysis of myelodysplastic syndromes with thrombocytosis: reclassification of the cases by WHO proposals.
2004
Myelodysplastic syndromes (MDS) show occasionally thrombocytosis, common feature of myeloproliferative diseases (MPD), with the overlapping of both disorders. Classically, thrombocytosis has been associated with some MDS subtypes: refractory anaemia with ringed sideroblasts (RARS), 5q- syndrome and those MDS with 3q chromosome rearrangements. The recent WHO classification recognises an unclassifiable MDS/MPD category including some of these disorders. Our aim is to determine the frequency of presentation, subtype classification and chromosome abnormalities of MDS with thrombocytosis diagnosed in our institution. Between 1990 and 2003 we studied 317 SMD patients according to FAB and WHO revi…
Development and initial validation of a composite disease activity score for systemic juvenile idiopathic arthritis
2020
Made available in DSpace on 2021-06-25T10:38:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-11-01 Healthway Objective. To develop a composite disease activity score for systemic JIA (sJIA) and to provide preliminary evidence of its validity. Methods. The systemic Juvenile Arthritis Disease Activity Score (sJADAS) was constructed by adding to the four items of the original JADAS a fifth item that aimed to quantify the activity of systemic features. Validation analyses were conducted on patients with definite or probable/possible sJIA enrolled at first visit or at the time of a flare, who had active systemic manifestations, which should include fever. Patients were reassessed 2 wee…
Presence of calreticulin mutations in JAK2-negative polycythemia vera
2014
Abstract Calreticulin (CALR) mutations have recently been reported in JAK2- and MPL-negative Myeloproliferative Neoplasms (MPN), particularly essential thrombocythemia (ET) and primary myelofibrosis (PMF).The clinical course of sporadic CALR-mutated patients seems to be more indolent than that of JAK2-mutated patients. In contrast, no CALR mutation has been found in the 647 published cases of Polycythemia Vera (PV) patients tested. Consequently, CALR mutations were considered exclusive to JAK2 and MPL mutations. Since 98% of PV patients harbor a JAK2 mutation (mostly the V617F mutation in exon 14 and more rarely, in exon 12), the absence of CALR mutations in PV seemed logical. Here, we desc…
