[Globulinopathy and hyperuricemia].

Investigation of the locomotor system of 20 patients is reported. One patient with arthrosis of the hip joint and concomitant osteonecroses had a myeloma. In 5 RA patients the manifestations of secondary amyloidosis are described. Among the patients with monoclonal gamma globulinemia two had polyarthritis and RA could not be excluded in one of them, one had arthritis of the ankle and foot joints, and one had a vasculitis characteristic of polyarteritis nodosa. Among those with polyclonal immunoglobulinemia one had RA, two had arthrosis of knees and hips, and two had ankylosing spondylitis. Furthermore four patients with alpha2-hyperglobulinemia which is important in evaluation of the alpha2-globulin peak in amyloidosis, are described. Three patients had cryoglobulinemia. In 10 patients hyperuricemia was found repeatedly (by the uricase method). Consequently in these diseases it is necessary to search clinically for crystal induced synovitides and arthropathies. The classification of globulinopathies and the method of their determination is indicated and particular investigations are recommended for such diseases, where the activity of the joint process does not correlate with laboratory findings.
