[Idiopathic inflammatory myopathies are systemic autoimmune diseases characterized by symmetrical weakness of proximal limb muscles. In the everyday practice it is not easy to treat idiopathic inflammatory myopathies. First-line therapy is based on corticosteroids. If there is no improvement in the symptoms and complaints in two months, a new immunosuppressant therapy has to be initiated. The aim of this summary is to present the biological agent rituximab in the therapy of this condition.]

Clinical Neuroscience
CANOMAD (chronic ataxic neuropathy, ophthalmoplegia, M-protein agglutination, disialosyl antibodies) syndrome is a rare polyneuropathy. IgM paraproteins react with ganglioside-containing disialylated epitopes resulting in dorsal root ganglionopathy and B-lymphocyte infiltration of cranial and peripheral nerves. Clinical features include ataxia, slight muscle weakness, areflexia, sensory- and cranial nerve symptoms. Case studies have reported the efficacy of rituximab and intravenous immunoglobulin (IVIg) treatments. We present the case of a 57-year-old man, who had difficulty walking, with numbness and clumsiness in all limbs. He had areflexia, vibratory sensation loss and ataxia. Laboratory tests showed IgM monoclonal components and disialosyl antibodies in the serum. Nerve conduction studies indicated severe sensorimotor demyelinating polyneuroradiculopathy. Despite IVIg and rituximab treatments, the patient’s disease course gradually worsened and he died of respiratory failure. Neuropathological examination revealed dorsal column- and dorsal root atrophy with mixed mononuclear cell infiltration. This article aims to draw attention to this syndrome, and the use of early potent immunosuppressive treatment to improve patients’ quality of life.

[Rheumatoid arthritis is a chronic, lifelong disease that causes severe joint deformity, reduces quality of life, and, if not treated appopriately, leads to disability and substantial premature mortality. Its treatment is a multistep procedure, where different grades of treatment options follow each other. Besides traditional, diseasemodifying antirheumatic drugs (DMARDs) and biological therapies inhibiting TNF, a new therapautic option is the use of a chimeric antibody, rituximab, which inhibits B lymphocyte function. This drug is an effective and safe choice for those patients who have received various anti- TNF therapies or do not tolerate TNF inhibition.]

[The present review is compiled of two parts, the first part aims to summarize the induction immunosuppressive therapy, the second part delineates the outcome and complications of ANCA-associated vasculitis. ANCA-associated vasculitis is a systemic disease, accompanied with rapidly progressive glomerulonephritis and severe, often life-threatening extrarenal complications. By early diagnosis and immediate initiation of immunosuppressive therapy, both patient and renal outcome have been substantially improved. The major aims of modern therapeutic protocols are, besides improving survival, to decrease immunosuppressive drug toxicity and avoid infections. Immunosuppression is based on the combination of large dose of corticosteroid and cyclophosphamide, which is advisable to supplement by plasma exchange. The B-cell depleting anti-CD20 monoclonal antibody rituximab, which has already been available in Hungary, has been proved to be similarly effective in newly diagnosed ANCA-vasculitis, and even more effective in a relapsing disease, compared to cyclophosphamide. Amongst rituximab’s further indications in this disease is the preservation of young women’s fertility, and it also has priority in some other special cases. Early diagnosis and prompt immunosuppressive treatment have resulted that ANCAvasculitis became a treatable disease with reasonably good clinical outcome, yet both the disease and the immunosuppressive medications frequently cause complications, which necessitate continuous alertness of the attending nephrologists.]

[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used medicines. During the last ten years several original publications, reviews and meta-analyses were published on the cardiovascular safety of NSAIDs and the results underlined their potentially harmful cardiovascular side effects. It can also be emphasized that there are substantial differences between different compounds, and the CV risk does not depend on the ratio of COX-1/COX-2 selectivity. Cardiovascular risk can be increased by all NSAIDs and paracetamol with the possible exception of naproxen and probably aceclofenac.]

[The therapy of rheumatoid arthritis (RA) is not always easy. Classical disease-modifying drugs are ineffective in about 10-15% of the cases. Furthermore, biologic agents, mainly tumor necrosis factor- α (TNF-α) inhibitors, may also be ineffective. Rituximab (RTX) is a B cell-inhibitory monoclonal antibody, which has been registered for the treatment of RA patients refractory to classical immunosuppressive agents including a TNF antagonist. Here we summarize the history of RTX therapy in RA including the presentation of the three major randomized clinical trials. We discuss the efficacy, safety of RTX, the practical points of RTX therapy, as well as some special considerations. The presented data suggest that RTX is a highly effective and safe biological, which can be used upon the inefficacy of any TNF inhibitor. RTX suppresses RA-associated inflammation, symptoms and decreases radiological progression. It may improve the functional capacity and quality of life of RA patients.]
