Reinach-Nord (BL, Suisse): Une ferme gauloise à l'aube de l'époque romaine

Situé dans la vallée de la Birse, Reinach appartient à l'arrière-pays de Bâle et est localisé dans la plaine du Rhin supérieur. Cette zone jouant un rôle important pendant la Guerre des Gaules ainsi que durant le Ier siècle apr. J.-C., on doit envisager de forts bouleversements du peuplement de cette région au changement d'ère. Grâce à des conditions favorables, les structures de La Tène finale au lieu-dit "Mausacker" sont très bien conservées et permettent de restituer une ferme laténienne avec deux phases différentes. Au même endroit se situe une villa gallo-romaine, mieux connue par ses enclos funéraires que par les structures résidentielles. Des études pluridisciplinaires financées par le Fonds national suisse (FNS) sont en cours pour les vestiges laténiens et gallo-romains de Reinach-Nord.

Effect of fibroblast growth factor NV1FGF on amputation and death: a randomised placebo-controlled trial of gene therapy in critical limb ischaemia

Patients with critical limb ischaemia have a high rate of amputation and mortality. We tested the hypothesis that non-viral 1 fibroblast growth factor (NV1FGF) would improve amputation-free survival.

Long-term safety of intramuscular gene transfer of non-viral FGF1 for peripheral artery disease

Peripheral artery disease is a progressive disease. Primary ischemic leg symptoms are muscle fatigue, discomfort or pain during ambulation, known as intermittent claudication. The most severe manifestation of peripheral artery disease is critical limb ischemia (CLI). The long-term safety of gene therapy in peripheral artery disease remains unclear. This four center peripheral artery disease registry was designed to evaluate the long-term safety of the intramuscular non-viral fibroblast growth factor-1 (NV1FGF), a plasmid-based angiogenic gene for local expression of fibroblast growth factor-1 versus placebo in patients with peripheral artery disease who had been included in five different phase I and II trials. Here we report a 3-year follow-up in patients suffering from CLI or intermittent claudication. There were 93 evaluable patients, 72 of them in Fontaine stage IV (47 NV1FGF versus 25 placebo) and 21 patients in Fontaine stage IIb peripheral artery disease (15 NV1FGF versus 6 placebo). Safety parameters included rates of non-fatal myocardial infarction (MI), stroke, death, cancer, retinopathy and renal dysfunction. At 3 years, in 93 patients included this registry, there was no increase in retinopathy or renal dysfunction associated with delivery of this angiogenic factor. There was also no difference in the number of strokes, MI or deaths, respectively, for NV1FGF versus placebo. In the CLI group, new cancer occurred in two patients in the NV1FGF group. Conclusions that can be drawn from this relatively small patient group are limited because of the number of patients followed and can only be restricted to safety. Yet, data presented may be valuable concerning rates in cancer, retinopathy, MI or strokes following angiogenesis gene therapy in the absence of any long-term data in angiogenesis gene therapy. It may take several years until data from larger patient populations will become available.

Insights on the role of diabetes and geographic variation in patients with critical limb ischaemia

Patients with critical limb ischaemia (CLI) unsuitable for revascularisation have a high rate of amputation and mortality (30% and 25% at 1 year, respectively). Localised gene therapy using plasmid DNA encoding acidic fibroblast growth factor (NV1FGF, riferminogene pecaplasmid) has showed an increased amputation-free survival in a phase II trial. This article provides the rationale, design and baseline characteristics of CLI patients enrolled in the pivotal phase III trial (EFC6145/TAMARIS).
