Immunosuppresseurs: usages systémiques et neurologiques [Systemic and neurological uses of immunosuppressive agents].

Involvement of the central or peripheral nervous system, frequently present in systemic inflammatory immune disorders, has to be considered a severe threat and requires aggressive immunosuppressive treatment to achieve rapid remission. This is usually obtained with high-dose systemic corticosteroids combined with cyclophosphamide. Once remission is obtained, immunosuppressive agents with a more favorable safety profile are needed to exert a corticosteroid-sparing effect and minimize adverse events. New therapeutic approaches are currently developed to treat autoimmune diseases, mostly linked to the definition of new indications for biological agents such as TNF-alpha antagonists and rituximab.

Disease activity in rheumatoid arthritis patients at initiation of biologic agents and 1 year of treatment: results from the Swiss SCQM registry.

OBJECTIVE: In Switzerland, the prescription of biologic antirheumatic agents in rheumatoid arthritis (RA) patients is not limited by stringent requirements from health authorities. The goals of this study were to: determine the characteristics of the Swiss patients at the initiation of biologics, compare them with other countries and evaluate whether different disease activity levels at initiation of therapy, resulting from distinct access to these treatment, influence their effectiveness. METHODS: This is a retrospective cohort study of RA patients followed in the Swiss register (SCQM-RA). Two thousand and sixty patients treated with biologics were retrieved. We present the disease characteristics and the patients' demographic data, at initiation and some effectiveness data after 1 year of treatment. RESULTS: Two thousand and sixty patients treated with biologics were retrieved. At initiation of treatment, the mean disease activity DAS (SD): 4.4 (1.4), number of previous antirheumatic treatments: 1.1, functional status HAQ: 1.1 (0.7) and median duration of illness: 5.5 years were significantly lower than in other published registries. The mean DAS: 3.3 (1.4) 1 year after initiation of therapy also appears lower than in other countries. Additionally, patients treated more recently (after 2005) had a significantly higher improvement in mean DAS. CONCLUSIONS: Data from the Swiss RA registry demonstrate that biologics are prescribed at a lower level of disease activity and after fewer prior DMARD failures than in most other countries, a practice that seems to correlate with overall lower absolute levels of disease activity and better patient outcomes after 1 year of treatment.

BAL9141, a novel extended-spectrum cephalosporin active against methicillin-resistant Staphylococcus aureus in treatment of experimental endocarditis.

The therapeutic efficacy of BAL9141 (formerly Ro 63-9141), a novel cephalosporin with broad in vitro activity that also has activity against methicillin-resistant Staphylococcus aureus (MRSA), was investigated in rats with experimental endocarditis. The test organisms were homogeneously methicillin-resistant S. aureus strain COL transformed with the penicillinase-encoding plasmid pI524 (COL Bla+) and homogeneously methicillin-resistant, penicillinase-producing isolate P8-Hom, selected by serial exposure of parent strain P8 to methicillin. The MICs of BAL9141 for these organisms (2 mg/liter) were low, and BAL9141was bactericidal in time-kill curve studies after 24 h of exposure to either two, four, or eight times the MIC. Rats with experimental endocarditis were treated in a three-arm study with a continuous infusion of BAL5788 (formerly Ro 65-5788), a carbamate prodrug of BAL9141, or with amoxicillin-clavulanate or vancomycin. The rats were administered BAL9141 to obtain steady-state target levels of 20, 10, and 5 mg of per liter or were administered either 1.2 g of amoxicillin-clavulanate (ratio 5:1) every 6 h or 1 g of vancomycin every 12 h at changing flow rates to simulate the pharmacokinetics produced in humans by intermittent intravenous treatment. Treatment was started 12 h after bacterial challenge and lasted for 3 days. BAL9141 was successful in the treatment of experimental endocarditis due to either MRSA isolate COL Bla+ or MRSA isolate P8-Hom at the three targeted steady-state concentrations and sterilized >90% of cardiac vegetations (P < 0.005 versus controls; P < 0.05 versus amoxicillin-clavulanate and vancomycin treatment groups). These promising in vivo results with BAL9141 correlated with the high affinity of the drug for PBP 2a and its stability to penicillinase hydrolysis observed in vitro.

Chitosan-based nanogels for selective delivery of photosensitizers to macrophages and improved retention in and therapy of articular joints.

Macrophages play key roles in inflammatory disorders. Therefore, they are targets of treatments aiming at their local destruction in inflammation sites. However, injection of low molecular mass therapeutics, including photosensitizers, in inflamed joints results in their rapid efflux out of the joints, and poor therapeutic index. To improve selective uptake and increase retention of therapeutics in inflamed tissues, hydrophilic nanogels based on chitosan, of which surface was decorated with hyaluronate and which were loaded with one of three different anionic photosensitizers were developed. Optimal uptake of these functionalized nanogels by murine RAW 264.7 or human THP-1 macrophages as models was achieved after <4h incubation, whereas only negligible uptake by murine fibroblasts used as control cells was observed. The uptake by cells and the intracellular localization of the photosensitizers, of the fluorescein-tagged chitosan and of the rhodamine-tagged hyaluronate were confirmed by fluorescence microscopy. Photodynamic experiments revealed good cell photocytotoxicity of the photosensitizers entrapped in the nanogels. In a mouse model of rheumatoid arthritis, injection of free photosensitizers resulted in their rapid clearance from the joints, while nanogel-encapsulated photosensitizers were retained in the inflamed joints over a longer period of time. The photodynamic treatment of the inflamed joints resulted in a reduction of inflammation comparable to a standard corticoid treatment. Thus, hyaluronate-chitosan nanogels encapsulating therapeutic agents are promising materials for the targeted delivery to macrophages and long-term retention of therapeutics in leaky inflamed articular joints.

Mélanome: une nouvette ère thérapeutique [Melanoma: a new therapeutic era].

Melanoma is the cancer with the fastest incidence increase in Switzerland. 30% of the cases arise before the age of 50 years. Once metastatic, the median survival under current systemic therapies is about 8 months, with less than 5% of patients alive at 5 years. Many efforts in the understanding of cellular biology, intracellular signaling pathways, as well as the role of cellular immunity have been made in the recent years. This has resulted in the development of novel and very promising therapies. In this review, we will cover the results obtained with targeted therapies such as "tyrosin kinase inhibitors" (TKI), as well as those obtained with a monoclonal antibody directed against the CTLA-4 receptor of lymphocytes.

Current multiple myeloma treatment strategies with novel agents: a European perspective.

The treatment of multiple myeloma (MM) has undergone significant developments in recent years. The availability of the novel agents thalidomide, bortezomib, and lenalidomide has expanded treatment options and has improved the outcome of patients with MM. Following the introduction of these agents in the relapsed/refractory setting, they are also undergoing investigation in the initial treatment of MM. A number of phase III trials have demonstrated the efficacy of novel agent combinations in the transplant and nontransplant settings, and based on these results standard induction regimens are being challenged and replaced. In the transplant setting, a number of newer induction regimens are now available that have been shown to be superior to the vincristine, doxorubicin, and dexamethasone regimen. Similarly, in the front-line treatment of patients not eligible for transplantation, regimens incorporating novel agents have been found to be superior to the traditional melphalan plus prednisone regimen. Importantly, some of the novel agents appear to be active in patients with high-risk disease, such as adverse cytogenetic features, and certain comorbidities, such as renal impairment. This review presents an overview of the most recent data with these novel agents and summarizes European treatment practices incorporating the novel agents.

Les connectivites: progrès thérapeutiques et place de la biothérapie [Connective tissue diseases: news in therapy, role of biologics agents].

Systemic lupus erythematosus and primary Sjögren's syndrom are the two major connective tissue diseases. A better knowledge of their physiopathology allows us today to propose an adapted therapy. Moreover progress concerns the oldest treatment, hydroxychloroquine, and biotherapy. Hydroxychloroquine is still an actual treatment for lupus, its positive effects are better understood today. Nevertheless it does not seem to be efficient to treat primitive Sjögren. Biotherapy targeting B lymphocytes seems efficient in these two connective tissue diseases. Anti TNF therapy is not recommended and seems to induce connective tissue diseases. The real news is the recent approval and reimbursement in Switzerland of the new drug belimumab (Benlysta) in case of moderate lupus.

Supervision of Community Health Agents in the Family Health Strategy: the perspective of nurses

Objective Analyzing the conceptions of supervision of nurses in the Family Health Strategy (ESF - Estratégia Saúde da Família) in relation to community health workers (ACS – Agente Comunitário de Saúde), taking for reference the work process and the power relations. Method A qualitative study, in which 18 interviews were carried out with nurses from the ESF in the countryside of the state of Goiás. Following transcription, the data were subjected to thematic content analysis and the following categories were identified: Supervision with that sees it all and Supervision is participating and working together. Results Among the findings, it is clear the character of control and monitoring that is carried out primarily through printed instruments and home visits, which constitute vertical and impositive relations, and suffer influence of the local health management. Another finding is the supervision as acting together and with the educational perspective. Conclusion The supervision carried out does not provide the changes intended by the ESF.

Role of T-cell-mediated inflammation in psoriasis: pathogenesis and targeted therapy

Psoriasis is one of the most common chronic, inflammatory, T-cell-mediated autoimmune diseases. Over the past decade, increased knowledge of disease pathogenesis has fundamentally changed psoriasis treatment, with the introduction of biologics, and this has led to a multitude of improved selective targets providing potential therapeutic options. Indeed, numerous pathogenesis-based treatments are currently in development, as psoriasis has also become increasingly relevant for proof-of-concept studies. The purpose of this review was to summarize current knowledge of psoriasis immunopathogenesis, focusing on the T-cell-mediated immune response and its initiation. The authors describe recent advances in psoriasis treatment and discuss pathogenesis-based therapies that are currently in development or which could be envisioned for the future. Although current biologics are well tolerated, several issues such as long-term efficacy, long-term safety, and high costs keep driving the search for new and better therapies. With further advances in understanding disease pathogenesis, more genomic data from psoriasis patients becoming available, and potentially the identification of autoantigens in psoriasis, current research should lead to the development of a growing arsenal of improved targeted treatments and to further breakthrough immunotherapies.
