Trastuzumab-emtansine induced pleural and pericardial effusions

2021

Introduction Trastuzumab emtansine (T-DM1) is an antibody-drug conjugate which combine trastuzumab (T), a monoclonal antibody targeting the human epidermal growth factor receptor-2 (HER2), and a cytotoxic molecule derived from maytansine (DM1). Case report We report the first case of T-DM1-associated pleural and pericardial effusions three weeks after the second course of T-DM1 in a patient with breast cancer. Drug-induced pleural and pericardial effusions was implicated in the absence of other etiologies. The Naranjo Scale indicated a probable drug-induced adverse reaction. Management & outcome: The patient fully recovered after thoracentesis and discontinuation of T-DM1. The patient h…

Treatment of sarcopenia by targeting Akt and muscle specific ubiquitin ligases. Evidence from mice and from a clinical trial

2017

Disuse muscle wasting may take place as a result of several such as joint immobilization, inactivity or bed rest. There are no good therapies to treat it. Allopurinol, a drug commonly used to treat hyperuricemia and gout, protects muscle damage, specially after exhaustive exercise and results in functional gains in old persons. Thus, we tested its effect in the prevention of atrophy of the soleus muscle after two weeks of hindlimb unloading in experimental animals (mice), and lower leg immobilization following ankle sprain in humans (Registration of the clinical Trial: EUDRACT2011-003541-17). We have found show that allopurinol protects against muscle atrophy in both mice and humans. The pr…

Type V collagen counteracts osteo-differentiation of human mesenchymal stem cells

2014

In search of novel gene signatures for osteo-differentiation of mesenchymal stem cells (MSCs), we submitted cDNA preparations from undifferentiated and differentiating MSCs to differential display- and semiquantitative-PCR and found down-regulation of COL5A1 in osteo-induced cultures at days 21 and 28, when the mineralized matrix accumulates. We also cultured osteo-differentiating MSCs onto type V collagen substrates and found a decrease in the accumulation of extracellular calcium compared to those grown in uncoated flasks. To our knowledge, this is first evidence that type V collagen might represent a stromal component that impairs osteogenesis.

Persistence ofYersinia antigens in peripheral blood cells from patients withYersinia enterocolitica O:3 infection with or without reactive arthritis

1998

Objective To assess the persistence of bacterial antigens in peripheral blood cells from patients with Yersinia enterocolitica O:3-triggered reactive arthritis (ReA). Methods Peripheral blood samples were obtained from 20 patients with Y enterocolitica O:3 infection (11 with ReA and 9 without). These samples were studied by immunochemical techniques for the presence of Yersinia antigens at the beginning of infection and up to 4 years thereafter. Synovial fluid samples from 6 of the 11 ReA patients were also studied. Results The Yersinia antigens lipopolysaccharide and heat-shock protein (HSP) were detected in peripheral blood mononuclear cells and polymorphonuclear phagocytes from all patie…

MINIMIZING INFLIXIMAB TOXICITY IN THE TREATMENT OF INFLAMMATORY BOWEL DISEASE

2008

Abstract Background Infliximab is a widely used biological agent for the treatment of inflammatory bowel disease, and has a favorable risk/benefit ratio. Aim It is useful to know that patients treated with infliximab are exposed to developing adverse events that could be reduced with a prudent and a rational clinical approach and by optimizing the treatment protocol. Methods PubMed (including Epub) was searched in October 2006 and again in March 2007. Results The high immunogenic potential of infliximab determines the antibodies that inhibit the effect of infliximab and the appearance of subsequent acute and delayed infusion reactions. Infliximab has an immunomodulatory effect, thus increas…

Treatment with a CO-releasing molecule (CORM-3) reduces joint inflammation and erosion in murine collagen-induced arthritis.

2008

Contains fulltext : 70589.pdf (Publisher’s version ) (Closed access) OBJECTIVE: CO-releasing molecules (CO-RMs) are a novel class of anti-inflammatory agents. We have examined the possible therapeutic effects of CORM-3 in collagen-induced arthritis (CIA). METHODS: Arthritis was induced in DBA-1/J mice by type II collagen. Animals were treated with CORM-3 (5 and 10 mg/kg/day, intraperitoneally) or the inactive compound iCORM-3 (10 mg/kg/day, intraperitoneally) unable to release CO, from days 22 to 31. Production of anti-type II collagen antibodies, cytokines and cartilage olimeric matrix protein (COMP) was evaluated by enzyme-linked immunosorbent assay, and prostaglandin E(2) (PGE(2)) by rad…

Emergence of severe spondyloarthropathy-related entheseal pathology following successful vedolizumab therapy for inflammatory bowel disease

2018

Objectives Vedolizumab (VDZ) blocks α4β7 integrin and is licenced for the treatment of IBD. It has been associated with mild SpA-related features, including sacroiliitis and synovitis. Herein we report a series of cases demonstrating the emergence of severe SpA-associated enthesitis/osteitis following successful IBD therapy with VDZ. Methods We evaluated 11 VDZ-treated patients with IBD across seven centres who developed severe active SpA and/or enthesopathy, with the aim of characterizing the VDZ-associated SpA or entheseal flares. Imaging features demonstrating particularly severe disease were recorded. Results De novo SpA developed in 9 of 11 patients and flare of known SpA in 2 patients…

Tacit tonality - Implicit learning of context-free harmonic structure

2009

Musical knowledge, like native language knowledge, is largely implicit, being represented without awareness of its complex structures and incidentally acquired through interaction with a large number of samples. Two experiments explore implicit learning of hierarchical harmonic structures of different complexity employing an artificial grammar learning paradigm. The experiments consisted of an incidental learning phase using a distraction task, and a testing phase employing the process dissociation procedure paradigm (Jacoby, 1991). Participants performed significantly above chance and recognised adjacent and long-distance dependencies in both experiments. Confidence ratings and inclusion/e…

Early Treatment of Systemic Juvenile Idiopathic Arthritis with Canakinumab and Complete Remission After 2 Years of Treatment Suspension: Case Report …

2019

Systemic juvenile idiopathic arthritis (sJIA) is an autoinflammatory disease characterised by fever and arthritis. We describe the case of a 14-year-old girl hospitalised with fever associated with rash, myalgia, arthralgia and polyarticular involvement. Examinations revealed increased levels of C-reactive protein, erythrocyte sedimentation rate, ferritin, triglycerides, leukocytes, neutrophils, lactate dehydrogenase, fibrinogen, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and γ-glutamyl transferase (GGT). Bone marrow biopsy showed polyclonal leukocyte activation. A genetic study revealed a heterozygous mutation of the MEFV gene, c.442G>C (E148Q), which is typical of…
