[Remarkable medical advances in rheumatology : may be ]. / Une révolution thérapeutique en rhumatologie : oui, mais .

The development of new drugs is a significant activity in a university hospital that favors access to therapeutic novelties to patients. Rheumatology, whose drug armamentarium was poor in the 1980s, has benefited from the huge progresses of immunology in the 1980-1990s, allowing a therapeutic revolution in whom the academic hospital of Liège (CHU Liège) has been strongly implicated. First protocols with anti-TNF-? monoclonal antibodies have been applied in 1997. Sixty-one protocols have been initiated in rheumatoid arthritis, 12 in ankylosing spondylitis, 10 in psoriatic arthritis, 9 in systemic erythematosus lupus, 3 in giant cell arteritis, 1 in polymyalgia rheumatica, 5 in osteoarthritis and 4 in osteoporosis. Potential and pitfalls will be discussed disease by disease and also by drug categories. The balance remains globally positive, but remission is far from be reached.

La recherche clinique médicamenteuse est une activité importante dans un hôpital universitaire. Elle valide des nouveautés thérapeutiques et fait bénéficier les patients de traitements novateurs bien avant leur mise sur le marché. La rhumatologie est une discipline dont l'arsenal thérapeutique était pauvre dans les années 1980, et les immenses progrès de l'immunologie, réalisés entre 1980 et 1995, lui ont permis de vivre une véritable révolution thérapeutique à laquelle notre service a amplement participé. C'est en 1997 que les premiers traitements par anticorps monoclonaux anti-TNF-? (les traitements dits biologiques) ont été utilisés au CHU de Liège. Soixante et une études seront initiées dans la polyarthrite rhumatoïde, 12 dans la spondylarthrite ankylosante, 10 dans la polyarthrite psoriasique, 9 dans le lupus érythémateux disséminé, 3 dans l'artérite temporale de Horton, une dans la pseudopolyarthrite rhizomélique, une dans la sclérodermie, 5 dans l'arthrose, 4 dans l'ostéoporose. Les espoirs et les déceptions observées dans les différentes indications, et avec les différentes molécules, sont analysées. Le bilan est globalement positif, mais les résultats encore insuffisants que pour arriver au concept de rémission.

[Fifteen years of use of anti-TNF antibodies in moderate to severe Crohn's disease: how to make the best of this experience]. / Quinze ans d'anti-TNF dans la maladie de Crohn: comment tirer le meilleur de cette révolution thérapeutique?

After fifteen years of use, the anti-TNF antibodies have become the corner stone of the treatment of moderate and severe Crohn's disease. The skill acquired over the years through experimental trials and clinical experience leads to increased therapeutic efficacy and minimized risks. These antibodies are introduced increasingly earlier in Crohn's disease as well as in a broader range of patients, aiming at changing the natural history of the diseases by avoiding the development of intestinal tissue damage and complications.

[Innovative therapies in inflammatory bowel disease at the CHU]. / Les thérapies innovantes au CHU dans les maladies inflammatoires chroniques de l'intestin (MICI).

Inflammatory bowel diseases (IBD), Crohn's disease and ulcerative colitis are frequent illnesses in western countries. They have a dramatic impact on the health-related quality of life. The new biological treatments developed for these diseases are potentially very effective, but are also expensive and may have significant side effects. In the present paper, the authors describe new biological therapies used during the past 10 years at the CHU. More than 20 therapeutic protocols were implemented. These protocols have given the patients the opportunity to gain very rapid access to new efficient therapies, to benefit from promising techniques for the evaluation of their pathology and to be submitted to a close follow-up that frequently called their treatment into question in the light of the most innovative options.
