Background:
Anaemia (AN) is frequently associated with inflammatory bowel diseases (IBD) and can negatively influence the quality of life of patients.
Aim:
To evaluate the prevalence and causes of AN in IBD.
Methods:
We prospectively performed a one-year multicentre observational study including all IBD cases attending six Units. We also investigated patients' main serological parameters.
Results:
The study population included 965 IBD patients (582 CD; 383 UC), of whom 142 were in-patients and 823 out-patients. AN was diagnosed in 134 out of 965 IBD patients (14%). No significant difference in AN prevalence was observed between CD and UC. The prevalence of AN was higher in the hospitalized IBD (26% in- vs. 11.7% out-patients; p<0.01; OR 2.2) and in active disease (CD: 34% active vs. 16% inactive; p<0.01; OR 2.1 - UC: 26% active vs. 19% inactive; p=0.03; OR 1.3). Iron deficiency was present in 72 patients (53.7%), AN of chronic diseases in 12 (8.2%), mixed type AN in 11 (8.2%), thalassemia in 9 (6.7%), and macrocytic AN in 8 (5.9%).
Conclusions:
In Southern Italy, AN is common in IBD and is more frequent in active disease and hospitalized patients. Iron deficiency still remains the major cause of AN in IBD.

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...
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
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...
