Context:
Non-adherence to therapy, in any degree is a common event and occurs in several circumstances. It is one of most common cause of fail in therapy of chronic diseases and Crohn's disease is not an exception.
Objective:
To evaluate in patients with Crohn's disease the prevalence and the risk factors to non-adherence to therapy.
Methods:
From July 2006, for 12 months, were included prospectively, for non-adhesion to therapy 100 patients with Crohn's disease that were assisted in a Center for Inflammatory Bowel Diseases of University Hospital of Federal University of Juiz de Fora, MG, in Brazil. A modified Morisky & Green Test for Measure of Adherence to Therapy was answered by all of them. According to test the patients were classified in two groups defined as adherence and non-adherence, respectively, and the last one was separated in intentional and non-intentional adhesion. Clinical, psychological and pharmacotherapeutics variables were sought to find the factors related to non-adherence.
Results:
Sixty four percent of total group were noticed to have a score of non-adherence to therapy according to used test and non-intentional was the most common type of behavior in such patients, and they demonstrated to be conscious of therapy. The comparison of adherent and non-adherent patients displayed a significant tendency to occurrence of non-adherence in younger (P = 0.07) and in non-white patients (P = 0.06). No correlation was observed in comparison of psychological and pharmacotherapeutics variables and non-adherence.
Conclusions:
In patients with Crohn's disease the prevalence of non-adherence to therapy is high (64%). The younger and non-white patients have higher propensity to non-adherence. In such circumstances efforts should be made to look for strategies to deal with this sort of people suffering from Crohn's disease, trying to increase the degree of adherence in this sort of patients.

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 colonic...

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 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...
