Retuximab

This report presents a 74-year-old renal transplant patient suffering of polymorphic-post-transplant-associated lymphoproliferative disease (P-PTLD) within an Eppstein-Barr Virus (EBV) associated mucocutaneous rectal ulcer (MCU). He was initially treated by stapled hemorrhoidopexy for a symptomatic grade III hemorrhoidal prolapse refractory to conservative treatment and rubber band ligations. This leads to severe urge, frequency and stool fragmentation. The symptoms were investigated with a number of interventions until a proctoscopy with biopsies finally revealed the diagnosis...

We report our clinical experience with rituximab in the treatment of 2 patients with idiopathic cutaneous angiitis who relapsed after treatment with high-dose corticosteroids and cyclophosphamide. A 39-year-old woman and a 51-year-old man presented with ulcerating maculopapular rash in both lower limbs which relapsed 6 months after treatment with a combination of high-dose corticosteroids and cyclophosphamide. After treatment with 2 g of rituximab, the first patient has still been in clinical remission for 32 months while the second has finished 28 months...

Use of immunosuppressors in the treatment of atopic dermatitis is an important innovation that reinforces the therapeutic arsenal in this chronic disease. Two such drugs are used topically for the treatment of atopic dermatitis. Tacrolimus exists in pommade form at a concentration of 0.1% for adults and 0.03% for children. Pimecrolimus, another calcineurine inhibitor with similar efficacy and tolerability, is not marketed in France. These products inhibit cytokine production by antigen-stimulated T lymphocytes...

OBJECTIVE: The aim of this study was to analyze the efficacy and toxicity of RNCE regimen in the treatment of relapsed or refractory B cell non-Hodgkin's lymphoma (NHL). METHODS: From January 2000 to December 2005, 46 patients with relapsed or refractory B cell NHL were treated by RNCE regimen with or without radiotherapy for the involved field. The clinical characteristics, response, toxicity and long-term survival results were analyzed retrospectively. RESULTS: A total of 46 patients were eligible...

To compare the efficacy and safety of RFT (retuximab, fludarabine, pirarubicin) with RCTVP (retuximab, cyclophophamide, pirarubicin, vindesine and prednisone) in 248 indolent B-cell non-Hodgkin's lymphoma (NHL) patients. Two hundred and forty-eight patients with indolent B-cell NHL were treated with combined chemotherapy, including RFT and RCTVP, from January 2002 to December 2010 in Tianjin Cancer Hospital. The rate of response, toxicity and long-term survival for the two regimens were analyzed retrospectively...

B cells play an important role in the pathogenesis of both systemic and organ-specific autoimmune diseases. Autoreactive B cells not only produce autoantibodies, but also are capable to efficiently present specific autoantigens to T cells. Furthermore, B cells can secrete proinflammatory cytokines and amplify the vicious process of self-destruction. B cell-directed therapy is a potentially important approach for treatment of various autoimmune diseases. The depletion of B cells by anti-CD20/19 monoclonal antibody Retuximab® used in autoimmune diseases therapy leads to systemic side effects and should be significantly improved...

A 64-year-old woman visited our hospital in December 2005 because of general malaise. Her hemoglobin level was 9.0 g/dl. Gastrointestinal fiberscopy detected a hemorrhagic gastric ulcer, which was considered as etiology of anemia. Abdominal ultrasonography showed bilateral hydronephroses and hydroureters. A urine test revealed pyuria and macroscopic hematuria, and urine culture revealed 10(8) colony-forming units of Escherichia coli per ml. Pelvic MRI showed thickening of the posterior wall and trigone of the urinary bladder...

The pathogenesis of rheumatoid arthritis (RA), the most common rheumatic disease, is still an unsolved puzzle. For many years, T-cells were the main focus of research, but recently, the B-cell drew more and more attention not least, due to the observation in humans that the anti-CD20 antibody Retuximab, which selectively depletes subsets of B-cells, lessens disease symptoms. A second novel approach to understand pathomechanisms that contribute to the development and progression of arthritis focuses on the sympathetic nervous system, which is known to moderate the function of immune cells, e...

In our experience, cancer is the second cause of death after renal transplantation. In fact, 27% of the deaths we observed at 15-year follow-up were due to neoplasm and 30% to cardiovascular disease. Cancer is a late complication that becomes more common after the fifth year of transplantation. The probability of suffering from cancer is 8.2% and 29.2% at 5 and 15 year, respectively. More specifically, after a 15-year follow-up, the probability rate for skin cancer is 16.4%, solid cancer 12.8%, lymphoproliferative disease (PTLD) 3% and Kaposi's sarcoma 2...

Denileukin diftitox (ONTAK) is indicated for the treatment of patients with cutaneous T cell lymphoma. Clinical experience with this drug in other lymphomas is limited. This case report concern a patient with stage IV follicular lymphoma who, relapsing after autologous transplant and having failed multiply systemic therapies, including retuximab and CHOP, achieved a prolonged remission with denileukin diftitox.

A phase I/II study was performed to analyse the ability of ifosfamide-based chemotherapy with rituximab to produce a turmour-free graft as well as the safety of retuximab prior to stem cell harvest and post high-dose chemotherapy. Twenty-two patients with B-cell non-Hodgkin's lymphoma were enrolled either having aggressive large-cell disease in relapse or at high/high-intermediate risk of relapse, or refractory lymphoma or mantle cell lymphoma, or indolent lymphoma. Chemotherapy consisted of ifosfamide 2 g/m2, days 1-3 with mesna, etoposide 100 mg/m2, days 1-3, and mitoxantrone 8 mg/m2 day 1, with figrastim...
