TNF and Pleural effusion: Anti‐TNFα inhibitor‐induced Lupus (ATIL) is a rare syndrome characterized by a wide array of symptoms ranging from skin manifestations to organ‐specific symptoms such as pleural effusions, pericardial effusions, hepatotoxicity, etc. Infliximab is implicated in most cases, and ATIL usually develops between the first month and 4 years of infliximab application.
