Objectives:
Ixekizumab, an interleukin (IL)-17A inhibitor, exerts its therapeutic effects in psoriasis by inhibiting the interleukin (IL)-17 signaling pathway. Common adverse reactions to ixekizumab include injection site reactions and upper respiratory tract infections (URIs), while occurrences of inflammatory bowel disease (IBD) and multiple mucosal ulcers are infrequent. We present a case of a 51-year-old man who developed multiple mucosal ulcers after ixekizumab treatment.
Methods:
A 51-year-old man presented to our hospital with a 1-month history of pharyngalgia. The flexible laryngoscope displayed mild hyperemia in the pharyngeal mucosa and tonsils, redness and swelling of the epiglottis, as well as multiple ulcers in the oral cavity, uvula, and epiglottis. These ulcers did not improve with conventional treatment.
Results:
Upon evaluation, the ulcers were an immune-related adverse event induced by ixekizumab. Consequently, a decision was made to discontinue the drug and initiate a therapeutic regimen including corticosteroids and thalidomide. Eventually, the patient's symptoms abated.
Conclusions:
Biologics are now becoming increasingly popular in psoriasis. It is vital for clinicians to be aware of this potential adverse event and to identify and intervene early to alleviate patients' suffering.

01:30Inflammatory 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...
01:27Inflammatory 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...

The therapeutic approach involves ensuring adequate rest, implementing drug therapy, promoting smoking cessation, making dietary modifications, and emphasizing long-term follow-up care.
Pharmacological management
The prevailing therapy for peptic ulcers involves a combination of managing the patient's current...
