Not just eosinophilic fasciitis.

J Med Life 2021 Jan-Mar;14(1):121-124

Department of Gastroenterology, Bucharest Emergency University Hospital.

This case report describes a rare case of progressive muscle weakness in a patient treated for eosinophilic fasciitis (EF) for many years before being diagnosed with a second autoimmune disease: dermatomyositis. Our case is a report of a 65-year-old male diagnosed with eosinophilic fasciitis 7 years before being evaluated in our service at Mayo Clinic in Jacksonville, Florida, due to progressive muscle weakness despite the chronic treatment with methotrexate. Contrast-enhanced magnetic resonance imaging of the lower extremity showed enhancement throughout the thigh musculature, which led us to pursue biopsies of the fascia and muscle in order to confirm the diagnosis of EF associated with myopathy.

Clinical perspective and practices on pleural effusions in chronic systemic inflammatory diseases.

Breathe (Sheff) 2020 Dec;16(4):200203

Oxford Centre for Respiratory Medicine, Churchill Hospital, Oxford University Hospitals NHS Foundation Trust, Oxford, UK.

Systemic inflammatory diseases are a heterogeneous family of autoimmune chronic inflammatory disorders that affect multiple systems within the human body. Connective tissue disease (CTD) is a large group within this family characterised by immune-mediated inflammation of the connective tissue. This group of disorders are often associated with pleural manifestations. Read More

Chemical exposure-induced systemic fibrosing disorders: Novel insights into systemic sclerosis etiology and pathogenesis.

Semin Arthritis Rheum 2020 12 19;50(6):1226-1237. Epub 2020 Sep 19.

Jefferson Institute of Molecular Medicine and Scleroderma Center, Thomas Jefferson University, Philadelphia, PA, United States.

Numerous drugs and chemical substances are capable of inducing exaggerated tissue fibrotic responses. The vast majority of these agents cause localized fibrotic tissue reactions or fibrosis confined to specific organs. Although much less frequent, chemically-induced systemic fibrotic disorders have been described, sometimes occurring as temporally confined outbreaks. Read More

Pharmacovigilance and drug-induced rare diseases: Strengths of the French Network of Regional Pharmacovigilance Centres.

Therapie 2020 Apr 13;75(2):207-213. Epub 2020 Feb 13.

Centre régional de pharmacovigilance et d'information sur le médicament, service de pharmacosurveillance, CHU de Tours, 37044 Tours, France. Electronic address:

The French-style organization in the field of rare diseases allows a close contact between reference centres and regional pharmacovigilance centres thanks to their implementation within the French university hospital. This collaboration leads to highlight more and more drug-induced rare diseases. Through several historical examples (eosinophilia-myalgia syndrome due to L-tryptophan, type 1 narcolepsy with H1N1 pandemic influenza vaccine, capillary leak syndrome, acquired von Willebrand syndrome), it remains clear that pharmacovigilance is the cornerstone of the alert system.

The Importance of Quality Specifications in Safety Assessments of Amino Acids: The Cases of l-Tryptophan and l-Citrulline.

J Nutr 2016 Dec 9;146(12):2643S-2651S. Epub 2016 Nov 9.

US Pharmacopeial Convention, Rockville, MD.

The increasing consumption of amino acids from a wide variety of sources, including dietary supplements, natural health products, medical foods, infant formulas, athletic and work-out products, herbal medicines, and other national and international categories of nutritional and functional food products, increases the exposure to amino acids to amounts far beyond those normally obtained from the diet, thereby necessitating appropriate and robust safety assessments of these ingredients. Safety assessments of amino acids, similar to all food constituents, largely rely on the establishment of an upper limit [Tolerable Upper Intake Level (UL)] considered to be a guide for avoiding high intake, above which adverse or toxic effects might occur. However, reliable ULs have been difficult or impossible to define for amino acids because of inadequate toxicity studies in animals and scarce or missing clinical data, as well as a paucity or absence of adverse event reporting data.

Eosinophilic fasciitis (EF) is a rare connective tissue disease characterized by symmetrical and painful swelling with a progressive induration and thickening of the skin and soft tissues. The diagnosis of EF is often based on the association of characteristic skin or subcutaneous abnormalities and a thickened fascia with an inflammatory infiltration, mostly composed of lymphocytes and eosinophils. A peripheral eosinophilia is frequently present (60-90%) but is not mandatory for the EF diagnosis. Read More

Prediction of drug-induced eosinophilia adverse effect by using SVM and naïve Bayesian approaches.

Med Biol Eng Comput 2016 Mar 5;54(2-3):361-9. Epub 2015 Jun 5.

College of Life Science, Northwest Normal University, Lanzhou, 730070, Gansu, People's Republic of China.

Drug-induced eosinophilia is a potentially life-threatening adverse effect; clinical manifestations, eosinophilia-myalgia syndrome, mainly include severe skin eruption, fever, hematologic abnormalities, and organ system dysfunction. Using experimental methods to evaluate drug-induced eosinophilia is very complicated, time-consuming, and costly in the early stage of drug development. Thus, in this investigation, we established computational prediction models of drug-induced eosinophilia using SVM and naïve Bayesian approaches. Read More

The disease presents with induration of the skin, connective tissue and the underlying muscle fascia, sometimes accompanied by myalgia, most commonly in the lower extremities. Unlike scleroderma, it presents with absence of visceral organ involvement and Raynaud's phenomenon. Read More

Zenith Specialist Pathology, South Brisbane, Queensland, Australia.

Cutaneous sclerosis, resembling that seen in subcutaneous morphea, is a feature of eosinophilic fasciitis and eosinophilia-myalgia syndrome, two conditions in which the kynurenine pathway is known to be activated. To investigate the possibility of activation of the kynurenine pathway in morphea, skin biopsies were taken from involved and non-involved sites in a series of three patients with morphea. Immunohistochemical stains for quinolinic acid and indoleamine 2,3-dioxygenase (IDO) were performed. Read More
