Etude de cohorte en France et en Suisse (7 centres). Analyse sémiologique des cas de maladie de Fabry (MF). Les cas index étaient 12 H, 5 F : âgemoyen au diagnostic 30 (9-58) et 34 ans (10-49), resp. Chez les H, le 1er symptôme était : acroparesthésies (acroP) (n=9) en moyenne à 8 ans (4-19). Le délai moyen premier symptôme-MF était de 17 ans (0-51), plus court en cas d'acroP qu'en cas d'autre symptôme révélateur (12.3 vs 19.6 ans). Les acroP « négligées » retardaient le diagnostic : angiokératomes (n=1, délai 28 ans), AVC du sujet jeune (n=2, délais 20 et 24 ans), insuffisance rénale terminale (n=1, délai 51 ans). Deux patients avaient une sémiologie complète : acroP, angiokératomes, hypohidrose, cornée verticillée, atteinte cérébrale, rénale (2 transplantations), cardiaque. Une hypoacousie était fréquente (n=6). Les errances diagnostiques ont été : SEP, neurobrucellose, PAN, cardiomyopathie hypertensive malgré l'absence d'HTA. Chez les F, le 1er symptôme était : acroP (n=3), cornée verticillée (n=1), angiokératomes (n=1). Le délai premier symptôme-MF était en moyenne de 15.6 ans (0-37). Tous les patients, à l'exception d'1 F, sont sous traitement enzymatique. Dans leurs familles, 47 autres cas (27H/20F) ont été diagnostiqués. La MF est à transmission dominante liée à l'X, avec expressivité variable. Elle atteint l'homme et la femme. Le diagnostic est trop tardif : l'interniste doit connaître la MF pour laquelle existe un traitement par alpha-galactosidase.

The biological activity of interleukin (IL)-2 and other cytokines in vivo can be augmented by binding to certain anti-cytokine monoclonal antibodies (mAb). Here, we review evidence on how IL-2/anti-IL-2 mAb complexes can be used to cause selective stimulation and expansion of certain T-cell subsets. With some anti-IL-2 mAbs, injection of IL-2/mAb complexes leads to expansion of CD8 T effector cells but not CD4 T regulatory cells (Tregs); these complexes exert less adverse side effects than soluble IL-2 and display powerful antitumor activity. Other IL-2/mAb complexes have minimal effects on CD8 T cells but cause marked expansion of Tregs. Preconditioning mice with these complexes leads to permanent acceptance of MHC-disparate pancreatic islets in the absence of immunosuppression.

Inflammatory bowel diseases are commonly complicated by weight and bone loss. We hypothesized that IL-15, a pro-inflammatory cytokine expressed in colitis and an osteoclastogenic factor, could play a central role in systemic and skeletal complications of inflammatory bowel diseases. We evaluated the effects of an IL-15 antagonist, CRB-15, in mice with chronic colitis induced by oral 2% dextran sulfate sodium for 1 week, followed by another 1% for 2 weeks. During the last 2 weeks, mice were treated daily with CRB-15 or an IgG2a control antibody. Intestinal inflammation, disease severity, and bone parameters were evaluated at days 14 and 21. CRB-15 improved survival, early weight loss, and colitis clinical score, although colon damage and inflammation were prevented in only half the survivors. CRB-15 also delayed loss of femur bone mineral density and trabecular microarchitecture. Bone loss was characterized by decreased bone formation, but increased bone marrow osteoclast progenitors and osteoclast numbers on bone surfaces. CRB-15 prevented the suppression of osteoblastic markers of bone formation, and reduced osteoclast progenitors at day 14, but not later. However, by day 21, CRB-15 decreased tumor necrosis factor α and increased IL-10 expression in bone, paralleling a reduction of osteoclasts. These results delineate the role of IL-15 on the systemic and skeletal manifestations of chronic colitis and provide a proof-of-concept for future therapeutic developments.
