None:
We present the case of a 15-year-old female with ulcerative colitis who developed an asymptomatic rise in creatine kinase and transaminases while on infliximab therapy. Additional rheumatologic workup revealed high-titer anti-nuclear antibody and positive anti-histone antibody, with the absence of myositis-specific autoantibodies. A drug-induced autoimmune phenomenon was suspected, with the patient lacking any muscle weakness or lupus features. The patient was subsequently switched to ustekinumab, which resulted in complete normalization of her labs while maintaining remission of her ulcerative colitis.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
