Background And Objective:
The true prevalence of the extraintestinal manifestations (EM) associated with inflammatory bowel disease (IBD) may vary depending on the geographic area, IBD population, location and duration of the disease, medication and diagnostic accuracy. The aim of this study was determine the prevalence of the major EM of IBD and their differences between Crohn's disease (CD) and ulcerative colitis (UC).
Patients And Method:
A prospective study with a total of 566 patients (295 CD with median follow up 11.6 years [range: 2-32 years] and 271 UC with median follow up 10.4 years [range: 2-36 years]. Data related to the clinical course, EM and laboratory tests were obtained at diagnosis and during follow-up.
Results:
EM related with IBD appeared al least once in 46.6% of the patients. Joints manifestations were the most common EM. The EM were equal frequent in UC (51.5%) as in CD (42.2%). Hepatobiliary manifestations (odds ratio [OR] = 1.91; 95% confidence interval [CI] 1.15-3.16; p = 0.007), venous thromboembolism (OR = 4.26; 95% CI, 1.3-15.4; p = 0.006) and arthralgias (OR = 1.59; 95% CI, 1.01-2.5; p = 0.035) were more frequent in UC than CD. Erythema nodosum (OR = 2.35; 95% CI, 1.13-5.0; p = 0.013) and peripheral arthritis (OR = 1.95; 95% CI, 1.02-3.74; p = 0.029) were more frequent in CD. The prevalences of ocular, and the rest of joint manifestations were not different according to UC or CD.
Conclusions:
Prevalence of EM in Spanish IBD patients is among the highest ever reported. The distribution of the EM observed is different between CD and UC. It is necessary to know to allow to prompt diagnosis and prevent undesirable complications.

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 transmural...

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...
