Doenças autoimunes são doenças universais, e os diagnósticos e tratamentos primários são habitualmente iniciados por clínicos em enfermarias ou ambulatórios, antes de serem encaminhados a especialistas. Além disso, pacientes em uso de biológicos internados em hospitais gerais têm sido cada vez mais frequentes na prática clínica. Conhecer o perfil de segurança, as indicações e os efeitos colaterais dessas drogas deve ser preocupação dos clínicos. Neste trabalho, foi realizada revisão de literatura sobre terapia biológica com rituximabe no tratamento das principais doenças autoimunes sistêmicas da prática clínica: artrite reumatoide, lúpus eritematoso sistêmico, vasculites relacionadas aos anticorpos anticitoplasma de neutrófilo, púrpura trombocitopênica imune e espondilite anquilosante.

AutoimmunAutoimmune diseases are universal diseases and primary diagnosis and treatment are typically initiated by internists in wards or outpatient clinics before being referred to specialists. In addition, patients on use of biologicals hospitalized in general hospitals have been increasingly common in clinical practice. Knowing the safety profile, the indications, and the side effects of these drugs should be a concern for the internists as well. In this study, the literature review was performed on biological therapy with Rituximab for treating the main systemic autoimmune diseases of clinical practice: rheumatoid arthritis, systemic lupus erythematosus, anti-neutrophil cytoplasmic antibody-associated vasculitides, immune thrombocytopenic purpura, and ankylosing spondylitis.

Rituximab has been used extensively in lymphoproliferative disorders. We evaluated the results of 64 consecutive patients treated between 2001 and 2004 at our institution. This included 54 males and 10 females. The median age was 54 years (range 17 to 85 years). One-fourth of patients were above 60 years. The histology was aggressive NHL in 35, indolent NHL in 22 and 7 cases were diagnosed as CLL. Among NHL, sixteen were in early stage (I/II) and the remaining forty-one were in advanced stage (III/IV) of disease. B symptoms were present in 47% of cases. A total of 33 were de novo cases and 31 were previously treated. Rituximab monotherapy was used in 17 cases. Rituximab was used in combination with chemotherapy in the other 47 cases. Infusional toxicity included anaphylaxis in one, hypotension in one and minor infusional reactions in four others. The patient who developed anaphylaxis required discontinuation of further Rituximab. Growth factors were used in 25 patients. Febrile neutropenia occurred in 19 patients. The overall RR (CR + PR) was 72%. One patient had stable disease and progressive disease was documented in 17 patients. A total of seven patients died, three due to progressive disease, three due to chemotherapy related toxicity and one due to an unrelated cause. We conclude that Rituximab is a valuable addition to the treatment armamentarium of lymphoproliferative disorders.
