Glycoproteins behaviour in ankylopoietic spondylarthritis.

Glycoproteins behaviour in ankylopoietic spondylarthritis (SA) is studied by dosing sialic acid in blood and urine on 12 patients in comparison with 10 rheumatoid polyarthritis (RP) and 39 other nonspecific osteo-articular disease cases; the values are referred to those found on normal persons. A significant statistic increase of the sialic acid is found in SA. There are also comparatively studied, on the same lots of patients, the ratio albumin/globulin (A/G), the values of the proteinaemia, of the globulins and the blood sedimentation rate (BSR).
