【 要旨 】 サイトメガロウイルス(cytomegalovirus;CMV)感染は潰瘍性大腸炎(ulcerative colitis;UC)にしばしば合併し,とくにステロイドや免疫調節薬投与中の患者や内科的治療に抵抗性を示す症例に多くみられる.UCに合併するCMV感染は増悪因子の一つと考えられているが,UCの病態に関与するか否かは未だ不明である.しかしながら,CMV感染を合併したUC 患者の一部には抗ウイルス療法が明らかに奏効する症例が存在し,病態への関与を窺わせる.したがって,UC治療中のCMV感染合併については積極的な診断が必要であり,その治療には腸管炎症の適切な制御と速やかなステロイドの漸減・離脱が重要と考えられる.

[ Summary ] Cytomegalovirus (CMV) infection persists throughout the lifespan in a latent state after primary infection. In patients with ulcerative colitis (UC), particularly those who are treated with corticosteroids and immunomodulatory agents, CMV is often reactivated. In addition, CMV infection occurs even in UC patients who have never been treated with immunosuppressive agents. CMV infection exacerbates colitis and sometimes leads to resistance to medical treatment and significant clinical morbidity in patients with UC. However, the exact role of concomitant CMV infection in the pathophysiological mechanism of UC remains unclear. Optimal control of colonic inflammation and withdrawal of corticosteroids therapy are important in the management of UC patients who are refractory to conventional immunosuppressive therapies and have concomitant CMV infection. In addition, anti‒viral therapy is effective for controlling colonic inflammation in some populations of such UC patients. Active diagnosis and intensified treatment for controlling colonic inflammation are required in the management of patients with UC and concomitant CMV infection.
