Antinuclear autoantibodies: Let’s simplify these complex issues!

Farah Tamirou, Frédéric A. Houssiau Published in the journal : July 2021 Category : Rheumatology

While antinuclear autoantibodies (ANA) are commonly searched for, their interpretation is not always easy, especially when requested in front of an atypical clinical picture. Quite often, ANA detection is in fact a chance discovery. This article aimed to review the place of ANA dosage in the clinic, as well as ANA’s meaning depending on the patient's context.

New-onset polyarthritis: usefulness of early remission

Emilie Sapart1*, Stéphanie Dierckx2*, Tatiana Sokolova1, Aleksandra Avramovska1, Laurent Meric de Bellefon3, Adrien Nzeusseu1, Bernard Lauwerys1, Patrick Durez1 Published in the journal : November 2020 Category : Rheumatology

Polyarthritis is a chronic inflammatory disease of immune origin that is characterized by a synovitis that progressively destroys the joints, which is at times associated with extra-articular manifestations.

This heterogenic rheumatic disease group can cause both structural and functional impairments, in addition to a decrease in patients' quality of life.

A better understanding of the disease's pathophysiology has led to the development of new encouraging therapeutic strategies for managing this disease.

Glucocorticoid-induced muscle atrophy: clinical presentation, physiopathological mechanisms, and therapeutic implications

Pauline Montigny (1), Jean-Paul Thissen (2) , Bernard Lauwerys (3), Frédéric Houssiau (3) Published in the journal : September 2019 Category : Rheumatology

Glucocorticoids (GC) are used in all medical areas because of their anti-inflammatory and immunosuppressive effects. Their undesirable effects are, however, much feared, in particular cortisone-induced myopathy (CD). This condition is characterized by insidious muscle atrophy, exhibiting an important prognostic role. CD is related to the GC-induced imbalance between muscle protein synthesis and degradation, promoting their degradation yet inhibiting their synthesis. We have herein undertaken a review focused on CD’s main pathophysiological mechanisms, along with a discussion on potential targets, such as myostatin, activin receptor Type IIB, TRAF6, and REDD1. To end with, practical recommendations for the fight against CD have been developed, including resistance exercises.

Spondyloarthritis: New insights in the pathophysiology and therapeutics perspectives!

A. Nzeusseu Toukap Published in the journal : February 2016 Category : Rheumatology

Spondyloarthritis (Spa) is a chronic immune-mediated inflammatory disease characterized by skeletal involvement (axial, an peripheral or both), at times associated with extra-articular manifestations (skin, gut, or eye). This heterogenic rheumatic disease may cause structural and functional impairments, in addition to a decrease in patients' quality of life. A better understanding of the disease's pathophysiology has led to new encouraging therapeutics strategies for managing this disease.

Synovial biopsy: an essential tool for guiding rheumatoid arthritis treatment?

L. Meric de Bellefon, M.S. Stoenoiu, Ch. Galant, A. Avramovska, S. Nieuwland Husson, A. Nzeusseu Toukap, B. Lauwerys, F.A. Houssiau, P. Durez Published in the journal : February 2016 Category : Rheumatology

Over the last years, the management of rheumatoid arthritis (RA) has been largely improved owing to the introduction of biologicals. These agents have been developed based on a better understanding of the disease pathophysiology. In the next years, the histopathological and molecular features of the synovial tissue will likely help clinicians better define RA treatment strategies.
