[Juvenile rheumatoid arthritis and related collagen diseases. Clinical aspects (author's transl)].
Juvenile rheumatoid arthritis or, more correctly, juvenile chronic polyarthritis with its many clinical manifestations can be separated into the Still-syndrome with acute beginning, high fever and a high percentage of extra-articulalar, i.e. visceral symptoms, and the chronic polyarthritis in the more strict sense with non-visceral symptoms. The subsepsis allergica should be regarded as a subseptic first stage of the Still syndrome. The Still-syndrome implies a systemic disease mainly of the reticulo-endothelial system, with carditis, nephropathy, recurrent erythemas, and a progressing polyarthritis. Later symptoms are amyloidosis, chronic nephritis, myo- and pericarditis, and artheriitis necroticans. Predominanly the involvement of the kidneys is the reasons for the high mortality rate of 13%. Chronic polyarthritis in the strict sense is similar in children and adults, though in children rheumatic factors are rarely detected. The exsudative form of arthritis tends to cause early deterioration. Joint symptoms are distributed asymmetrically and show locally inflammed growth otherwise less common in Still-syndrome. Spondylitis cervicalis rapidly causes ankylosis. Atlanto-axial-arthritis with consequent atlanto-axial dislocation can be the reason for neurological disturbances. Juvenile mono- or oligo-arthritis often turns into polyarthritis; but for joints the prognosis is more favourable. In contrast, rheumatoid iridocyclitis as found in 22% of the cases causes unfavourable complications because symptoms are not noticed in time so that treatment is often too late. Juvenile spondylitis ankylosans begins with a peripheral arthritic stage which is not easily distinguished from chronic polyarthritis. The male sex, mono- or oligoarthritis of the outer extremities, pain in the heel, atlanto-axial-arthritis, iridocyclitis, and a positive HLA of 27 give a diagnostic clue. -- Characteristics of the therapy will be discussed.
