まとめ
双極性障害(BD)と炎症性腸疾患(IBD)は頻繁に併発し、患者の健康と治療に影響を与える。共有される炎症経路と腸脳相関がこれらの疾患を結びつけ、統合的なケアが必要である。
背景:
- 双極性障害(BD)と炎症性腸疾患(IBD)は頻繁に併発し、複雑な治療上の課題をもたらす。
- 共有される炎症メカニズムが関与しているが、BDとIBDの間の臨床的および病態生理学的な相互作用は十分に理解されていない。
研究 の 目的:
- 双極性障害と炎症性腸疾患の併存に関する既存の文献をレビューする。
- BD-IBDの重複の臨床的、疫学的、およびメカニズム的側面を特徴づける。
主な方法:
- 2000年1月から2025年5月までの査読付き文献のナラティブレビューを実施した。
- PubMed、Web of Science、PsycINFOでBD、IBD、併存、炎症マーカーに関連する用語を使用して検索を行った。
- BD-IBDの重複に関する臨床的、疫学的、またはメカニズム的データを報告する研究をスクリーニング後に含めた。
主要な成果:
- BDはIBD患者の3-7%に影響を与え、一般人口(1-2%)よりも有意に高い。
- 併存するBD-IBDは、入院、重度の消化器および精神症状、QOLの低下と関連している。
- 精神科薬による炎症の悪化やIBD治療薬による気分不安定化の可能性など、複雑な治療相互作用が存在する。
- 調節不全のサイトカイン、腸内細菌叢の変化、および遺伝的要因が関与するメカニズム経路である。
結論:
- BDとIBDの併存は、全身性炎症によって媒介される双方向性の腸脳神経免疫軸を浮き彫りにする。
- この併存疾患の管理には、統合的で学際的なケアが不可欠である。
- 今後の研究では、患者のアウトカム改善のため、縦断的研究と標的抗炎症介入を優先すべきである。

Bipolar Disorder
586
Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

Irritable Bowel Syndrome I: Introduction
885
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Chronic Bowel Disorders: Introduction
722
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Inflammatory Bowel Disease II: Crohn's Disease
912
Introduction
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
854
Introduction
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...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
609
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
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...
