Abstract

Artrite psoriásica (AP) é uma artrite inflamatória soronegativa de causa desconhecida. Classicamente, a AP apresenta cinco formas clínicas, sendo a oligoartrite assimétrica a mais comum. Descrevemos o caso de uma paciente com AP refratária às drogas modificadoras da doença, que evoluiu com hepatite medicamentosa após quimioprofilaxia com isoniazida, administrada previamente ao tratamento com anti-TNF&#945;. Em virtude do risco de ativação de tuberculose (TB) latente pela administração de anti-TNF&#945;, da hepatotoxicidade decorrente do tratamento da TB, e baseado no fato de o tratamento da AP se assemelhar ao da artrite reumatoide, optou-se pelo tratamento empírico com abatacepte. Aproximadamente vinte dias após a segunda dose do biológico, a paciente evoluiu com importante melhora clínica, resolução da artrite, regressão das lesões de pele e melhora da anemia e das provas de atividade inflamatória.<br>Psoriatic arthritis (PA) is an inflammatory seronegative arthritis of unknown origin. Classically, PA has five clinical forms, and asymmetric oligoarthritis is the most common type. We describe the case of a patient with PA refractory to disease-modifying drugs, who developed drug-induced hepatitis after chemoprophylaxis with isoniazid, administered prior to the treatment with an anti-TNF&#945; agent. Due to the risk of activating latent tuberculosis with the administration of anti-TNF&#945; and hepatotoxicity onset caused by the TB treatment and based on the fact that the treatment of PA is similar to the treatment of rheumatoid arthritis, a decision was made to use the empirical treatment with abatacept. Approximately twenty days after the second infusion of the drug, the patient showed clinical improvement, resolution of the arthritis, almost complete disappearance of the skin lesions and improvement of anemia and inflammatory tests.
