乾癬性関節炎とアトピー性皮膚炎の併存が治療方針のヒントになる可能性
乾癬性関節炎患者の3分の1がアトピー性疾患を有し、鼻炎や喘息より皮膚炎が多い
国立グリゴレティポパ大学医学部(ルーマニア)のGeorgiana Strugariu氏らは、PsA患者64人を対象とした後ろ向き解析で、活動性疾患に対して生物学的製剤を投与されているPsA患者におけるADについて検討した。対象者は外来リウマチ科で最長10年間追跡された。
解析の結果、患者の約3分の1がアトピー性疾患を有しており、アトピー性鼻炎やアレルギー性喘息と比較してADの発症率が高いことが分かった〔それぞれ6例、3例、10例(31.6%、15.8%、52.6%)〕。ADでは、慢性痒疹、慢性単純性苔癬、湿疹の3つの形態学的パターンが認められた(それぞれ3例、1例、6例)。ADを併発するPsA患者は、皮膚アトピーの発症が全例で遅く(成人期)、他にも若年、都市部出身、男女比が均等、疾患コントロールの達成により多くの生物学的製剤への切り替えが必要など、特徴的なプロファイルを示した。
著者らは、「乾癬やPsAの患者をアトピーおよびADについてスクリーニングすることは、特定の治療クラスに反応する患者の、より具体的なプロファイルを作成する上で重要な役割を果たし、これらの患者に、より良好なコントロールとより長い治療効果を与える可能性がある」と述べている。
Coexistence of Psoriatic Arthritis, Atopic Dermatitis May Offer Treatment Insights
One-third of psoriatic arthritis patients have atopic diseases, most often dermatitis versus atopic rhinitis and allergic asthma
MONDAY, May 13, 2024 (HealthDay News) -- Psoriatic arthritis (PsA) and atopic dermatitis (AD) can coexist, and the presence of both conditions may mean special attention should be given to selecting optimal treatment, according to a study published online April 17 in the Journal of Personalized Medicine.
Georgiana Strugariu, from "Grigore T. Popa" University of Medicine and Pharmacy in Romania, and colleagues examined AD in patients with PsA and receiving biologics for their active disease in a retrospective analysis of 64 patients with PsA. Participants were followed in an outpatient rheumatology department for up to 10 years.
The researchers found that about one-third of the patients had atopic diseases, with a higher incidence of AD versus atopic rhinitis and allergic asthma (10 cases versus six and three cases, respectively [52.6 percent versus 31.6 and 15.8 percent, respectively]). Within AD, three morphological patterns were recognized, including chronic prurigo, a chronic lichen simplex, and eczemas (three, one, and six cases, respectively). Late onset of skin atopy was seen for all PsA patients with concomitant AD (in adult life), and they exhibited a specific profile, including being younger, being from urban settings, being equally distributed among genders, and requiring switching to a higher number of biologics in order to achieve disease control.
"Screening patients with psoriasis and PsA for atopy and for AD could play an important role in creating a more specific profile of respondents to a particular therapeutic class and give these patients the chance for better control and a longer therapeutic response," the authors write.
