Prof. dr. Loic Guillevin from France and Prof. dr. Cees G.M. Kallenberg from the Netherlands join the CSSA Advisory Board.

Two highly respected vasculitis researchers, Pr. Loic Guillevin of the French Vasculitis Study Group and Pr. Cees G.M. Kallenberg of the University Hospital Groningen in the Netherlands, have accepted invitations to serve on the CSSA Medical Advisory Board.

The CSSA is grateful for their association with our organization and for their highly regarded research in the field of vasculitis. Because of the rarity of CSS and the fact that patients are scattered throughout the world, the CSSA is thrilled that researchers from many countries are working together to study Churg-Strauss syndrome.

Dr. Guillevin and his collaborator, Dr. Christian Pagnoux, sent the following article as an introduction to Dr. Guillevin and the French Vasculitis Study Group:

Pr. Loïc GUILLEVIN and his research group, the French Vasculitis Study Group

Pr. Loïc Guillevin is a specialist in internal medicine, who has been involved for many years in the management and care of patients affected by systemic vasculitides, like Churg–Strauss syndrome, but also Wegener’s granulomatosis, classical or hepatitis B virus (HBV)-related polyarteritis nodosa, microscopic polyangiitis or mixed essential cryoglobulinemia. In the early 1980’s, he created a research network in France dedicated to vasculitides and called it the French Vasculitis Study Group (FVSG), in which more than 600 French physicians have been regularly involved.

Very early on, the group developed international contacts, e.g., with Belgium or the United Kingdom, and actively participates in the European Vasculitis Study (EUVAS) Group and the International Network for the Study of Systemic Vasculitides (INSSYS). More than 20 prospective therapeutic trials have been conducted so far by the FVSG, with subsequent publications in renowned international medical journals. Concerning Churg–Strauss syndrome, the FVSG’s main studies have provided essential information on its frequency in France [1], its predisposing and precipitating factors [2-4], its clinical presentation [5-7], evolution, prognostic factors [8-11] and treatment [12-15].

One of the major practical findings in/derived from those studies is that patients with the most severe forms of the disease, identified as those having specific renal, cardiac, gastrointestinal and/or central nervous system involvement, should receive a combination of corticosteroids and immunosuppressant, mostly monthly cyclophosphamide pulses. Conversely, those patients without poor prognostic factors can be treated with corticosteroids alone. Ongoing and planned studies are aimed at further improving our knowledge concerning the pathophysiogenesis of Churg–Strauss syndrome, based upon developing laboratory research activities, optimizing therapy, in conjunction with an attempt to reduce sequelae related to the disease or its treatment, and finally, to lower the number of patients who, despite having achieved remission, remain persistently corticodependent, primarily because of their asthma.

Pr Loïc Guillevin and his main collaborators (Pr Luc Mouthon, Dr Pascal Cohen, Dr Alfred Mahr, Dr Christian Pagnoux, Dr Véronique Le Guern, Dr Boris Bienvenu) are currently based in the Department of Internal Medicine, Hôpital Cochin, Université Paris 5, Paris, France (

In 2003, the FVSG created its web homepage, , which is primarily dedicated to continuing medical education, but the development of a patients’ homepage, with the help of patients and patients’ associations, is planned for the very near future.
