Antineutrophil cytoplasmic antibodies have recently been demonstrated in sera of patients with inflammatory bowel disease. We are reporting here our experience among 94 patients with Crohn's disease and 25 with ulcerative colitis. The indirect immunofluorescence assay with alcohol fixed neutrophils has been used. The presence of antineutrophil cytoplasmic antibodies was significantly associated to the ulcerative colitis 61% VS 17% (p < 0.001). The fluorescence had a perinuclear pattern among all but one suffering from ulcerative colitis. Among the patients suffering from ulcerative colitis there was no relationship between the presence of antineutrophil cytoplasmic antibodies and the activity or the localisation of the disease. Among the 9 patients operated for their ulcerative colitis, 4 were ANCA positive and remained so after proctocolectomy. The existence of antineutrophil cytoplasmic antibodies is useful for the diagnosis of some unclassifiable colitis. Their presence may be used as an argument in favour of some disturbances of the immunoregulation of the disease. [less ▲]

For many years, chemotherapy, hormonotherapy and immunotherapy were the mainstay of cancer treatment. Recent advances in our knowledge of cell biology and particularly of cancer cell transformation, growth and metastasis have led to the identification of specific pathways playing a role in the pathophysiology of cancer. New drugs specifically developed to control these targets are collectively named "targeted therapies". Two types of targeted therapies are available: kinase (mainly tyrosine kinase) inhibitors (suffix -nib) are small molecules binding directly to the intracellular kinase domain and acting as competitive inhibitor of ATP binding and monoclonal antibodies (suffix -mab) directed towards specific cell surface receptors or their ligands to prevent receptor activation. This paper will only review monoclonal antibodies (mabs). Thirty years after their discovery mAbs have become efficient therapeutic tools. Progress in molecular engineering as well as improved knowledge of cell signalling pathways together with a better selection of the targets turned them into valuable treatments. Several mAbs are currently licensed for the treatment of hematological or solid malignancies and many others are expected in the near future. [less ▲]

Clinical efficacy of antiplatelet agents administration to reduce ischemic complications has supported the concept of atherothrombosis and plaque rupture. Specifically, administration of monoclonal antibody against platelet membrane receptor glycoprotein IIb/IIa was shown to be highly effective whenever percutaneous intervention is performed in the setting of unstable coronary syndrome. The in-hospital use of glycoprotein IIb/IIIa is unanimously recommended in these situations. [less ▲]

SUMMARY : Type 1 diabetes is characterized by the autoimmune- mediated destruction of the insulin-producing beta cells of the pancreatic islets of Langerhans. Several cells are potentially implicated in the selective destruction of beta cells, including the beta cells themselves, and T-lymphocytes and B- lymphocytes that are working as antigen-presenting cells. Both types of lymphocytes play also a role in the progressive loss of graft function after islet transplantation. Therefore, immunotherapy may represent a great opportunity to prevent, treat or even cure type 1 diabetes, and the input of monoclonal antibodies (mAb) appears crucial in such a strategy. The concept has first been validated in various animal models, especially the classical one of the NOD mouse. During recent years, promising results of a few clinical trials have been published with the administration of anti-CD3 mAbs targeting T lymphocytes at the time of diagnosis of type 1 diabetes. Results showed a more sustained residual insulin secretion during the following months associated with a reduction in insulin needs. Interesting results may also be expected from the use of anti-CD20 mAbs targeting B lymphocytes. Finally, when considering immunosuppressive therapies after beta-cell transplantation, mAbs, especially those blocking interleukin-2, are already used in clinical practice, but new trials are expected with mAbs targeting T or B lymphocytes. Thus, mAbs might be efficacious in a near future in the prevention (when administered early in the natural course of the disease, in high risk patients) and the treatment of type 1 diabetes, and therefore could avoid, or at least minimize, the constraints of intensive subcutaneous insulin therapy.

Directed against the CD20 antigen on B lymphocytes, rituximab (MabThera) is now incorporated in the first line therapy of symptomatic follicular as well as diffuse large B cell non-Hodgkin's lymphoma and offers superior response and survival rates. 90Y ibritumomab tiuxetan (Zevalin) combines the specificity of rituximab for the CD20 antigen and the therapeutic effect of β irradiation. Given in monotherapy, it constitutes an interesting alternative therapy for follicular lymphomas in second relapse. Alemtuzumab (MabCampath) recognizes the CD52 antigen and offers encouraging results in chronic lymphocytic leukemia resistant to classical chemotherapy. [less ▲]

Since their inception in the 1970's, monoclonal antibody therapies became increasingly efficient and common in numerous medical conditions and their use in neurology has been boosted during the last couple of years with the rise of natalizumab (Tysabri). Furthermore, if most monoclonal antibodies currently assessed in neurologic conditions remain considered as experimental, they may soon become first-line approved treatments in a broad range of neuromuscular and demyelinating diseases. Since the introduction of new therapies is likely to unravel specific adverse events and sui generis iatrogenic disorders, it is important to be able to recognize the side-effects of monoclonal antibodies delivered for neurological or non-neurological diseases.

Renal transplantation is the best treatment for end-stage renal disease, but requires efficient immunosuppressive therapy. The latter has evolved over recent years with the development of more powerful drugs and of monoclonal antibodies with very specific target. The first monoclonal antibodies, acting against the interleukin 2 receptor, named basiliximab and daclizumab, have showed an excellent tolerance profile and efficacy to reduce acute graft rejection. However, in spite of these properties, the development of delayed graft function or the graft and patient survivals at 1 year were not modified by the use of such specific treatment. One potential advantage could yet be a decreasing need for corticosteroids and sometimes calcineurin inhibitors which could provide some long term benefits for the renal graft, but also the patient. Alemtuzumab, another monoclonal antibody, aimed at the membrane glycoprotein CD52, can also decrease the incidence of acute rejection and the depth of the required immunosuppressive therapy. Other antibodies are still in development with some interesting preliminary results which however demand confirmation in larger studies. [less ▲]

About 9,500 new breast cancers are diagnosed in Belgium every year. Improvement of our knowledge of altered molecular events leading to the proliferation of tumor cells has resulted in the development of targeted therapies in subgroups of cancers. One of the first validation of targeted therapy is the anti-HER-2 monoclonal antibody trastuzumab (Herceptin) in patients with overexpression of human epidermal growth factor receptor type 2 (HER2) occurring in 20 to 25% of invasive breast carcinoma. Trastuzumab binds the extracellular juxtamembrane domain and is only active in tumor with HER2 gene amplification detected by fluorescence in situ hybridization (FISH). The results from randomized trials have rapidly lead to the approvement of the drug in the metastatic and then in the adjuvant setting. Another targeted therapy, also approved in the treatment of breast cancer, is the monoclonal antibody bevacizumab with an anti-VEGF (Vascular Endothelial Growth Factor) activity. We will review the benefit of these targeted therapies in breast cancer and their role in the treatment of breast cancer. [less ▲]
