Brief Summary

Inflammatory bowel diseases (IBD), including Crohn's disease and ulcerative colitis, are characterized by extraintestinal manifestations in approximately 30% of cases. Only 3% of these manifestations are neurological diseases, but they have serious consequences for the patient's health, and often constitute a significant diagnostic problem. Neurological symptoms may precede the appearance of IBD symptoms by up to several years. According to the available literature, symptoms of neurological diseases are more common in men and are usually diagnosed after the diagnosis of IBD, but they are rarely associated with exacerbations of the disease. The most common of these are demyelinating diseases such as multiple sclerosis. The very application of treatment in patients with IBD may also play an important role in the development of neurological diseases of various types and pathogenesis. The use of immunosuppressants and therapy with biological drugs may lead to the impairment of the central nervous system due to changes in the white matter of the brain, a predisposition to opportunistic infections, John Cunningham virus infections and the resulting progressive multifocal leukoencephalopathy (PML). So far, the literature describes the occurrence of many neurological diseases in patients with coexisting IBD, caused by side effects of the treatment itself, cerebral vascular diseases or caused by immune disorders. Cases of Wernicke encephalopathy caused by vitamin B1 deficiency have also been reported. A broad term that defines symptoms of not only neurological diseases is encephalopathy. By definition, it means damage or disease that affects the brain. It occurs when the way the brain works is changed due to a change in the body. These changes cause changes in the psyche, causing confusion and a change in typical behavior. Encephalopathy is not a single disease entity but a disorder with complex pathophysiology. It is a serious disease that, if untreated (or rather its underlying cause), leads to permanent brain damage. Due to the variety of symptoms and their variable severity, the diagnosis of encephalopathy often escapes the team of chronically ill patients. Patients with IBD are such a group - young patients whose severe, incurable disease changes their philosophy of life. The influence of IBD on encephalopathy symptoms has not been evaluated so far. This study is designed to answer the question of whether encephalopathy occurs in people with IBD. By extrapolating the incidence of encephalopathy in people with another immunologically mediated disease, Hashimoto's disease, we hypothesized that such a disorder could also occur in people with IBD. We assume that autoimmune mechanisms underlying the disease will contribute to the etiopathogenesis of the phenomenon, similarly to thyroid disease. Additionally, with increasing incidence in the scientific literature, it is stated that in about 30% of cases, IBD symptoms overlap with functional bowel diseases such as Irritable Bowel Syndrome (IBS), so we plan, in the questionnaire presented to patients, to include questions regarding the coexistence of these disorder as described in the Roman IV Criteria.

Outcome Measures

Primary Outcomes (1)

  • Prevalence of encephalopathy in patients with Inflammatory Bowel Disease

    Finding the presence or absence of symptoms of encephalopathy in people with IBD

    2-3 Months

Secondary Outcomes (1)

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with inflammatory bowel diseases who within 12 months were: * hospitalized at the Department of Gastroenterology in Bielanski Hospital in Warsaw, * patients consulted at the Gastroenterology Outpatient Clinic * patients reporting for outpatient endoscopic examinations at the Endoscopy Unit Among these people, a group of patients treated with biological or biomimetic drugs will be distinguished, due to the correlation, as indicated in the literature, between the use of anti-TNF drugs and the occurrence of disturbances in the functioning of the nervous system.

You may qualify if:

  • Patients with Inflammatory Bowel Disease (Ulcerative Colitis, Crohn's Disease)

You may not qualify if:

  • The study group will exclude people who do not respond to pharmacological treatment, including biological / biomimetic drugs, and will be referred for surgery, as well as people with previously diagnosed neuropsychiatric diseases. In addition, the study will exclude patients with nervous system diseases and liver diseases who are suspected or diagnosed with encephalopathy.
