Objectives:
Cardiovascular complications have been frequently described in Inflammatory Bowel Disease (IBD). Both Crohn disease and Ulcerative Colitis are characterized by malabsorption of some micronutrients, such as carnitine, which is a very important element for myocardial metabolism, being demonstrated that its deficiency correlates with heart involvement in coeliac disease. Aims of this study are to evaluate cardiac function in IBD patients asymptomatic for cardiovascular diseases and to correlate the cardiac data with the profile of carnitine esters plasma levels.
Materials And Methods:
The study was carried out on 20 IBD patients by comparison with 18 sex- and age-matched clinically healthy controls. Personal and familial history, physical examination, standard electrocardiogram and echocardiogram were performed in all subjects. Complete panel of nutritional status parameters and serum levels of free carnitine and its esters were evaluated both in IBD patients and control subjects.
Results:
Isovaleryl-carnitine, Tiglyl-carnitine, Octenoylcarnitine and Decanoyl-carnitine, were found to be significantly lower in IBD patients. Significant correlations were found between some carnitine esters and echocardiographic parameters although total and free carnitine were meanly more elevated in IBD. No statistically significant differences in echocardiographic parameters were found between IBD patients and control subjects.
Conclusions:
Deficiency of some isoforms of carnitine, especially those esterified with short chain fatty acids, may play an important role in cardiac involvement in course of IBD and could lead, over time, to dilated cardiomiopathy.

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...
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...

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...
