Abstract:
Collagenous colitis is a chronic inflammatory condition and one type of a bigger entity, microscopic colitis. Collagenous colitis is associated with autoimmune diseases, such as psoriatic arthritis, suggesting an immune mechanism involved in the pathogenesis of the disease. New onset and flares of inflammatory bowel disease have been associated with the use of secukinumab, but no cases of microscopic colitis have been reported yet. We present a case of a 41-year-old woman with psoriatic arthritis treated with secukinumab who developed chronic diarrhea and was found to have collagenous colitis.

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 is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
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...
