PYROGLOBULIN AND HUMAN ARTHROPATHY

*Ibrahim M S Shnawa

Abstract

Two cases of pyroglobulins were found among 138(1.45%) arthropathy human patients sera but not from the 25 apparently normal control subjects sera. The first of which was showing; Semi-opaque and viscous precipitate. While the second reveals jelly-like precipitate. These pyroglobulins were coexisted with copyroprecipitates in a rat of 20:138(14.49%).Whereas, these two cases have shown clinical significant concentration of the inflammatory immunoproteins ,CRP 48.5, 57.5 mg /IU/ml and the normoglobulin responses, Rheumatoid factor 57, 68 mg/ml. The author is of the opinion holds that there may be a presence of pyroacting B lymphocyte clones within their immune system components that are involved in this pyroglobulin response initiation and mounting, since it has been reported with different isotypes and different clinical settings, though their rarity.
