[Results of leukocyte migration inhibition test against elastin in joint diseases (author's transl)].

UNLABELLED: The purpose of this work was to report the results of the test TML inhibition of leukocytes' migration, using elastin, by Soborg and Bendixen method, modified with elastin rates of 100 micrograms and 200 micrograms/ml, in joints disease. We verified that the test is generally negative in healthy controls (1 TML positive out of 26 cases); we studied 72 patients, and 38 out of them had a positive test. TML is frequently positive in Horton disease, spondylarthritis, rheumatoid polyarthritis without corticoids, collagen disease; in this cases there is a significant difference of migration between patients and controls group. We also noted a positive TML in infections arthritis and other inflammatory but not in joint's diseases with alteration of elastic tissue (scabs and lung's injury).

IN

CONCLUSION

TML positive test with elastin, is not a specific test of articular injury neither a proof of its immunologic nature but it contributes in diagnostic for joints diseases.
