Zusammenfassung
Bei einer 66-jährigen Patientin mit einem seit 10 Jahren
bekannten Morbus Crohn kam es erstmals parallel zu einem schweren Schub einer
Psoriasis pustulosa generalisata und eines floriden M. Crohn. Ein zweiter
zeitgleicher Schub beider Erkrankungen entwickelte sich kurz nach dem Absetzen
der Therapie mit Prednisolon, Methotrexat und Mesalazin.
Die pathogenetischen Konzepte von M. Crohn und Psoriasis pustulosa
generalisata ähneln sich auf immunologischer Ebene. Da beide
Krankheitsbilder vergleichbare Muster von proentzündlichen Zytokinen,
Chemokinen und Entzündungszellen (T-Zellen und neutrophile Granulozyten)
aufweisen, könnte die Psoriasis pustulosa generalisata eine weitere,
seltenere extraintestinale Manifestation des M. Crohn darstellen.
Generalized pustulous psoriasis: A novel extraintestinal
manifestation of Crohn’s disease?
A 66-year-old female patient suffering for 10 years from
Crohn’s disease firstly presented with a parallel outbreak of generalized
pustulous psoriasis and Crohn’s disease. A second synchronous
exacerbation of both disorders occurred after discontinuation of treatment with
prednisolone, methotrexate, and mesalazine. As to their pathogenetic concepts,
both disease entities reveal similar immunologic alterations, i. e. comparable
patterns of cytokines, chemokines, and inflammatory cells (T cells and
neutrophils). Generalized pustulous psoriasis, therefore, might develop as
hitherto undescribed, more rare extraintestinal manifestation of Crohn’s
disease.
