CRYOGLOBULINS IN CASE OF RHEUMATOID ARTHRITIS IN CHILDREN: CONNECTION WITH THE AGE FACTOR AND CHANGES IN THE URINE ANALYSIS

Abstract

33 healthy children and 39 patients withjuvenile rheumatoid arthritis have been studied. The level of cryoglobulins has been up to 80 mcg/ml in healthy children (43,5+28,3 mcg/ml) being decreased with the age. The level of cryoglobulins has been accounted for 651 mcg/ml(91,2+110,2 mcg/ml) being increased with the age in children with juvenile rheumatoid arthritis. Significant correlation between the level of cryoglobulins and activity of disease has been revealed. There were no differences of the level of cryoglobulins in children with systemic and articular forms of arthritis as wellas in children with changed and normal urine analyses.
