BACKGROUND: The use of biotherapies in Trypanosoma cruzi infection can provide an understanding about effects of these highly diluted medications. OBJECTIVES: To evaluate different treatment schemes and dynamizations of biotherapies prepared from blood trypomastigotes (buffy coat) in mice infected with T. cruzi. METHODS: Swiss mice infected with Y strain of T. cruzi were divided into two experiments. Experiment 1, all treated groups received biotherapy 7dH (10 μL/mL ad libitum) in different treatment schemes: TB7dH - treated 3 days before infection; TBA7dH - treated 3 days before and after infection; TBAe...

BACKGROUND: During rheumatoid arthritis (RA), steroids and biotherapies are used alone and combined. Efficacy has been established in clinical trials but their differential effects at the cellular level are less documented. The aim was to study these cellular effects using an in vitro model with synoviocytes interacting with peripheral blood mononuclear cells (PBMC) to reproduce the interactions in the RA synovium. METHODS: Activated-PBMC were cocultured with RA synoviocytes during 48 h...

BACKGROUND: Cell therapy is an emerging potential biotherapy for critical limb ischaemia (CLI) patients who are not eligible for revascularization. However, the findings on this technique's efficacy are inconsistent. Trials investigating this topic focused on the more severe CLI patients who were often beyond any therapy. Therefore, identifying those who may truly benefit from cell transplantation is now warranted. To this end, we studied the prognostic value of tcPO2 for major amputation after 1 year in patients treated with bone marrow-derived cells...

Ras mutations and overexpression of the Ras protein; i.e., p21Ras, are main causes of cancer development and progression, which has made the Ras gene and p21Ras important targets for therapy of Ras-driven cancers. We previously prepared recombinant adenovirus KGHV100 based on replication-defective adenovirus type 5, which could intracellularly express anti-p21Ras single chain fragment viable antibodies (scFv) and repress tumor growth in vitro and in vivo. However, the anti-tumor effects of this anti-p21Ras scFv were limited by short-term scFv expression due to a replication defect of KGHV100...

OBJECTIVES: Studies suggest that rheumatoid arthritis (RA) is less frequent in African populations. However, no recent precise data exists for Afro-Caribbeans. The EPPPRA project is a prospective epidemiological survey to describe prevalence and clinical aspects of RA in the French West Indies (Martinique, Guadeloupe, French Guiana). METHODS: EPPPRA involved all rheumatologists from the French West Indies who included all patients with a known clinical diagnosis of RA, during a one-year period...

Although a glucocorticoid (GC)-sparing strategy is needed for patients with giant cell arteritis (GCA) suffering from refractory disease or serious treatment-related complications, evidence of efficacy in this setting of immunosuppressive drugs and biotherapies is lacking. Herein, we evaluated the GC-sparing effects and tolerability of addition of dapsone (DDS) to prednisone therapy in patients with GCA. We retrospectively assessed data on 18 GCA patients who received DDS as a first-line treatment (DDS-1 group) and 52 patients who received it as a second- or third-line treatment for refractory GCA, with or without excessive GC-related toxicity (DDS-2 group)...

The objective of the treatment of colorectal cancer patients with unresectable liver metastases should be clearly defined at the outset. Potentially resectable patients should be distinguished from clearly unresectable patients. In defining resectability, it is important to take into account both anatomic characteristics and patient characteristic (comorbidities, symptoms, age). According to this evaluation, treatment should be tailored to each patient. The most widely accepted standard is doublet cytotoxic regimen plus biotherapy (anti-EGFR or anti- VEGF antibodies according to RAS status, but some patients could benefit from an intensified regimen, as triplet chemotherapy +/- bevacizumab, or intraarterial treatments (hepatic arterial infusion, radioembolization or chemoembolization), in order to allow resectability...

The antidiabetic effects of Lactobacillus. paracasei subsp. paracasei G15 and Lactobacillus. casei Q14 in high fat diet and streptozotocin-induced type 2 diabetic (T2D) rats were evaluated in this study. The strains were separated from Chinese traditional fermented dairy food. Administration of G15 and Q14 for 6 weeks significantly improved the glucose tolerance and reduced the HbA1c levels in T2D rats. The probiotic treatment reduced the intestinal mucosal permeability and improved the epithelial barrier function through modification of the gut microbiota, which in turn lowered circulating LPS and inflammation cytokines, including IL-1β and IL-8, and eventually alleviated the inflammatory status and islet β-cell dysfunction...

In contrast to traditional strategies based on external driving forces, an internal path for intratumoral delivery is explored by degrading the tumor microenvironment component hyaluronan. Natural hyaluronidase PH20 and constructed long-acting PH20-Fc have been used to achieve this objective. It has been then evaluated how these agents facilitate the diffusion of the following typical therapeutic agents varying in nanoscales: doxorubicin (≈1.5 × 1.0 × 0.7 nm) chemotherapy, trastuzumab (10-15 nm) biotherapy, and gold nanorod (≈100 × 35 nm) thermotherapy...

INTRODUCTION: Although biotherapy has greatly improved the prognosis of RA many patients have still recourse to an orthopaedic surgery. The current recommendation for scheduled surgery is to discontinue administration of the biological agent two to six weeks before surgery. Reinitiating anti-TNF therapy is proposed when the patient has healed. We wanted to know whether patients treated with anti-TNFα were exposed to an infectious risk undergoing a surgical procedure and if discontinuation of anti-TNFα therapy altered the risk of surgical infection...

Systemic lupus erythematosus (SLE) is an autoimmune disease with a polymorphic presentation. The variability in the clinical expression and severity of SLE makes new treatments both essential and challenging to develop. Several biotherapies targeting different pathophysiological pathways have been developed over the past 15 years. The results of Phase II trials were encouraging but rarely borne out by Phase III trials. Recent data, which are discussed in detail in this review, allowed belimumab - a monoclonal antibody against BLyS (B-lymphocyte stimulator) - to become the first biotherapy approved for use in SLE...

Mevalonate kinase deficiency is a rare, autosomal recessive, auto-inflammatory disease. This results from mutations in the gene MVK coding for the enzyme mevalonate kinase. This enzyme is involved in cholesterol and isoprenoids synthesis. Depending partially of the residual activity of the mevalonate kinase, the clinical spectrum realizes a continuum which extends from the mild phenotype of the hyperimmunoglobulinemia D and periodic fever syndrome (HIDS) to a lethal form of mevalonic aciduria. The HIDS is characterized by recurrent episodes of fever with an intense inflammatory syndrome, accompanied with lymphadenopathy, abdominal pain, diarrhea, arthralgia, hepatomegaly, splenomegaly and skin rash...

Inflammatory T cells are thought to be central to the pathogenesis of juvenile idiopathic arthritis. In particular, recent evidence has underlined the importance of a balance between Th17 and Treg cells. Several mechanisms have come to light that control this reciprocal relationship. Moreover, it has been shown that in certain conditions, Th17 cells can shift toward a nonclassic Th1 phenotype. Anti-rheumatic biologic therapies may interfere with these mechanisms and re-establish immune tolerance.

The intestinal microbiome plays an important role in the pathogenesis of inflammatory bowel disease (IBD). We are able to use the microbiome as a therapeutic target with use of fecal microbiota transplantation (FMT) for cure of recurrent Clostridium difficile infection. Given our ability to target the dysbiotic state with FMT, its use as therapy in IBD has tremendous potential. This overview discusses the practical considerations of FMT therapy with respect to our current understanding of safety and efficacy in IBD, screening for donors and recipients, specimen handling and storage, methods of delivery, and regulatory considerations...

The delivery of small interfering RNA (siRNA) is an attractive therapeutic approach to treat several pathologies, such as viral infections or cancers. However, the stability and the efficacy of these biotherapies are still a major obstacle to their use. Cationic liposomes (DOTAP/Chol/DOPE 1/0.75/0.5M ratio) have been complexed to siRNA (lipoplexes) in order to be administrated by the vaginal route, in the context of HPV16 induced cervical preneoplastic lesions. To overcome the constraint of the cervico-vaginal mucus, PEGylation is required to allow the diffusion of lipoplexes through it...

SummaryCancer stem cells (CSCs) are a subpopulation of tumor cells that have strong self-renewal capabilities and may contribute to the failure of conventional cancer therapies. Hence, therapeutics homing in on CSCs represent a novel and promising approach that may eradicate malignant tumors. However, the lack of information on validated targets of CSCs has greatly hindered the development of CSC-directed therapeutics. Herein, we describe the Cancer Stem Cells Therapeutic Target Database (CSCTT), the first online database to provide a rich bioinformatics resource for the display, search, and analysis of structure, function, and related annotation for therapeutic targets of cancer stem cells...

Leukopenia is a considerably common complication of tocilizumab [TCZ] and rituximab [RTX] therapy. RTX-induced leukopenia typically exhibits delayed onset. While agranulocytosis has been reported linked to RTX treatment of lymphoma, this complication rarely occurs in rheumatoid arthritis (RA) treatment and, to our knowledge, has never been reported in association with TCZ therapy. We herein report four agranulocytosis cases in three patients, with the first two cases suspected to be secondary to human parvovirus B19 (PVB19) infection...

Noninfectious uveitis is a kind of recurrent autoimmune disease and a major cause of blindness in clinical practice. Corticosteroids are the conventional medication, but have severe side effects for long-term users, and some refractory patients are treated with immunosuppressive agents. Because the pathogenesis of uveitis is related to the autoimmune imbalance mediated by CD4 + T lymphocytes. The macrophages, lymphocytes and some cytokines are involved. The immunomodulatory therapy is targeted to block the lymphocytes, cytokines or their receptors, so as to control the inflammatory damage or minimize the recurrence of the disease...
