Background And Aims:
Inflammatory bowel disease (IBD) has many characteristics of autoimmune diseases. Sensorineural hearing loss has been reported in many autoimmune diseases. Little is known about hearing loss in patients with IBD.
Methods:
A prospective blinded comparative study was conducted over a 3-year period. IBD patients and controls underwent a complete otorhinolaryngeal examination and eudiometry test.
Results:
Altogether 105 participants (76 patients and 29 controls) took part in this study. Mean age was 36, 51 % were males, and 40 % of the patients were presently hospitalized due to IBD exacerbation. Audiometric examination revealed that any hearing loss (mild to severe) was found in 29 (38 %) of the IBD population, compared to 4 (14 %) of the control group (p = 0.02). Extraintestinal manifestation (EIM) was present in 33/76 (43 %) of IBD patients. Any hearing loss and moderate to severe hearing loss were found in 17/33 (52 %) and 7/33 (21 %) in the EIM-positive group compared to 12/43 (28 %) and 4/43 (9 %) in the EIM-negative group (p = 0.036 and p = 0.14, respectively). Out of patients over the age of 40 with other EIMs, all 11/11 (100 %) of patients had any hearing loss compared to 8/12 (66 %) of patients over the age of 40 without other EIMs, p = 0.035.
Conclusions:
Hearing loss may be another EIM of IBD. It is found in 38 % of IBD patients and in up to 52 % of patients with other EIMs and increases over the age of 40. Early hearing evaluation should be recommended to these high-risk IBD patients.

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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
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...
