[Therapy for secondary arthropathies: from psoriasis and Reiter's disease to hemochromatosis].

Arthralgia is one of the most common complaints in Western society. The classification of joint diseases with respect to genesis is crucial for the determination of adequate treatment. For inflammatory arthropathies, treatment options have expanded significantly over the last decade. This review summarizes the current treatment of psoriatic arthritis and Reiter's disease, both belonging to the spectrum of seronegative spondyloarthropathies. Regardless of our increasing knowledge of chondrogenesis, the treatment of osteoarthritis is still more or less symptomatic. Premature age of onset and the atypical joint distribution of osteoarthritis should bring metabolic diseases, for example hemochromatosis, into consideration.
