Anti-tumor necrosis factor (TNF) drugs are frequently used today especially in rheumatology and inflammatory bowel diseases (IBD).
Sometimes paradoxical side effects develop due to these agents. In the case in this article, Crohn's disease (CD) has developed as an
intestinal paradoxical side effect due to the use of anti-TNF in an individual who has been diagnosed with ankylosing spondylitis
(AS) since childhood. For this reason, the treatment process was rearranged and nursing care was planned based on Gordon's
functional health patterns for the patient who was hospitalized.
