Cardiac sarcoidosis in a patient with ulcerative colitis: A case report and literature review

Rationale:
Both ulcerative colitis (UC) and sarcoidosis are chronic inflammatory diseases with unknown etiologies and are rare. However, the odds ratio in UC patients has been reported to range from 1.7 to 2.1, suggesting a potential etiology between sarcoidosis and UC. Furthermore, the underlying etiologies of UC and sarcoidosis remain unidentified. Sharing the experience of a UC patient with cardiac sarcoidosis could provide valuable insights to prevent sudden death in UC patients.
Patient Concerns:
A 71-year-old Japanese woman was diagnosed with UC at 58-year-old and maintained remission on mesalazine treatment. She complained of just palpitation; therefore, she consulted a cardiologist.
Diagnoses:
The patient received a diagnosis of cardiac sarcoidosis with complicating ulcerative colitis based on the results of N-terminal prohormone of the brain natriuretic peptide (NT-proBNP), imaging examinations, and histology.
Intervention:
The patient was treated with prednisolone and methotrexate. The prednisolone was then tapered, and the methotrexate dose was adjusted based on her symptoms, imaging results, and laboratory findings.
Outcome:
She no longer had any symptoms, and the abnormal FDG uptake had disappeared after 2 years.
Lesson:
In UC patients, periodic or additional (in case of symptomatic) electrocardiography and NT-proBNP are recommended for the early detection of cardiac sarcoidosis, a life-threatening complication.

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, 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...
