OBJETIVO: Avaliar as complicações imediatas da aplicação de agentes anti-TNFα no Centro de Dispensação de Medicação deAlto Custo do HC-FMUSP. PACIENTES E MÉTODOS: Foram incluídos todos os pacientes que receberam agentes anti-TNFα entre agosto/2007 e março/2009.As complicações imediatas (até 1 hora após o término da aplicação) foram classificadas em leves (cefaleia, rash, tontura, prurido, náuseas), moderadas (febre, urticária, palpitação, dor torácica, dispneia, variação da pressão arterial de 20 a 40 mmHg) ou graves (febre com calafrios, dispneia com sibilância, variação da pressão arterial > 40 mmHg). RESULTADOS: Foram avaliados 242 pacientes: 94 (39%) com artrite reumatoide, 64 (26%) com espondilite anquilosante, 32 (13%) com artrite psoriásica, 26 (11%) com artrite idiopática juvenil e 27 (11%) com outros diagnósticos. O número total de aplicações foi de 3.555, sendo 992 (28%) de adalimumabe, 1.546 (43%) de etanercepte e 1.017 (29%) de infliximabe. Complicações imediatas foram observadas em 39/242 (16%) pacientes. As complicações ocorreram em 45/3.555 (1,2%) aplicações. Estas foram mais frequentes com infliximabe comparado com adalimumabe (3,7% vs. 0,5%, P OBJECTIVE: To evaluate the immediate complications of anti-TNFα drugs at the "Center for Dispensation of High Cost Medications" of HC-FMUSP. PATIENTS AND METHODS: All patients who received anti-TNFα agents between August 2007 and March 2009 were included in this study. Immediate complications (up to 1 hour after the injection) were classified as mild (headache, rash, dizziness, itching, nausea), moderate (fever, urticaria, palpitation, chest pain, dyspnea, blood pressure variations between 20 and 40 mmHg), or severe (fever with chills, dyspnea with wheezing, variations in blood pressure > 40 mmHg). RESULTS: Two hundred and forty-two patients were evaluated: 94 (39%) with rheumatoid arthritis, 64 (26%) with ankylosing spondylitis, 32 (13%) with psoriatic arthritis, 26 (11%) with juvenile idiopathic arthritis; and 27 (11%) with other diagnoses. A total of 3,555 injections were administered: 992 (28%) adalimumab, 1,546 (43%) etanercept, and 1,017 (29%) infliximab. Immediate adverse events were observed in 39/242 (16%) patients. Injectionrelated complications were observed in 46/3,555 (1.2%) injections. They were more common with infliximab than adalimumab (3.7% vs. 0.5%, P < 0.0001) and etanercept (3.7% vs. 0.25%, P < 0.0001). Complications were classified as mild 14/45 (31%), moderate 21/45 (47%), and severe 10/45 (22%), and occurred mainly in the first six months of treatment (56%) and after intravenous injections, especially (76%) in the first hour. CONCLUSION: Although rare, acute reactions can be severe, being observed more commonly after the initial injections, both intravenous and subcutaneous. More studies are necessary to define whether those immunobiological agents should be administered only in facilities capable of managing medical emergencies.
