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…
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…
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…
Evidence for Positive Selection in the Capsid Protein-Coding Region of the Foot-and-Mouth Disease Virus (FMDV) Subjected to Experimental Passage Regi…
2001
We present sequence data from two genomic regions of foot-and-mouth disease virus (FMDV) subjected to several experimental passage regimens. Maximum-likelihood estimates of the nonsynonymous-to-synonymous rate ratio parameter (dN/dS) suggested the action of positive selection on some antigenic sites of the FMDV capsid during some experimental passages. These antigenic sites showed an accumulation of convergent amino acid replacements during massive serial cytolytic passages and also in persistent infections of FMDV in cell culture. This accumulation was most significant at the antigenic site A (the G-H loop of capsid VP1), which includes an Arg-Gly-Asp (RGD) cellular recognition motif. Our …
Lack of reactivation of tuberculosis in patients with psoriasis treated with secukinumab in a real-world setting of latent tuberculosis infection
2022
Background Some biologics for psoriasis, especially anti-tumor necrosis factor (TNF)-alpha therapies, may re-activate latent tuberculosis (TBC) infection with consequent morbidity and mortality. However, there is a low reported incidence of conversion to positive TBC status among patients with psoriasis treated with second-generation biologic therapies, particularly anti-interleukin (IL)-17 therapies such as secukinumab. Objectives To evaluate the safety profile of secukinumab in psoriasis patients with latent TBC infection. Methods Real-life data were collected by retrospective chart review on patients with moderate-to-severe psoriasis who showed positivity for TBC screening at baseline an…
RSV disease in infants and young children: Can we see a brighter future?
2022
Respiratory syncytial virus (RSV) is a highly contagious seasonal virus and the leading cause of Lower Respiratory Tract Infections (LRTI), including pneumonia and bronchiolitis in children. RSV-related LRTI cause approximately 3 million hospitalizations and 120,000 deaths annually among children <5 years of age. The majority of the burden of RSV occurs in previously healthy infants. Only a monoclonal antibody (mAb) has been approved against RSV infections in a restricted group, leaving an urgent unmet need for a large number of children potentially benefiting from preventive measures. Approaches under development include maternal vaccines to protect newborns, extended half-life monoclon…
Good clinical response, remission, and predictors of remission in rheumatoid arthritis patients treated with tumor necrosis factor-α blockers: The GI…
2007
OBJECTIVE: To assess the prevalence of good clinical response and remission in rheumatoid arthritis (RA) patients with longstanding disease treated with anti-tumor necrosis factor-alpha (TNF-alpha) drugs at outpatient clinics. METHODS: Retrospective national study of 14 academic tertiary referral rheumatology medical centers. RA patients with a Disease Activity Score (DAS28) > 3.2 were defined as having active disease and could start TNF-alpha blockers. All patients received one TNF-alpha blocker plus methotrexate (10-20 mg/wk). At the third month the patients were categorized as responders or nonresponders, based on improvement of at least 0.25 of the Health Assessment Questionnaire (HAQ).…
Etanercept maintains the clinical benefit achieved by infliximab in patients with rheumatoid arthritis who discontinued infliximab because of side ef…
2007
Objective: To evaluate the efficacy of switching to etanercept treatment in patients with rheumatoid arthritis who already responded to infliximab, but presented side effects. Methods: Charts of 553 patients with rheumatoid arthritis were retrospectively reviewed to select patients who responded to the treatment with infliximab and switched to etanercept because of occurrence of adverse effects. Clinical data were gathered during 24 weeks of etanercept treatment and for the same period of infliximab treatment before infliximab was stopped. Disease Activity Score computed on 44 joints (DAS-44), erythrocyte sedimentation rate (ESR) 1st hour, Visual Analogue Scale (VAS) of pain, Health Assessm…
