[Value of MS associated factors for test procedures in multiple sclerosis: 2. Angers' MS-induced substance in the LAI test].
Attempts to find test systems specific for multiple sclerosis are directed to the investigation of MS-associated factors in serum. Basing on the methods of the adherence of antigen-reactive leukocytes, the MSRM (MS-related material) a substance conditioned by the disease was derived from blood of MS-patients and applied in the leukocyte adherence-inhibition (LAI)-test. The mean values in the LAI-test showed a significant difference between MS, the other neurological diseases (OND) and the normals. For the limiting value mean NK +/- 2 s a positive LAI-effect resulted in 58% of the intermittent and in 43% of the chronic-progredient cases of MS, yet also in 11% of the OND. The fact that the rate of detection is lower than that reported by Angers, could depend on factors caused by the method used or by anomalies of immune regulation in MS (including the so-called blocking factors in serum). The results received with LAI-test applying the MSRM don't allow any definite diagnostical assessment specific for MS.
