title: [Clinical course and changes of soluble interleukin-2 receptor and soluble forms of intercellular adhesion molecule-1 (ICAM-1) in serum of multiple sclerosis patients].
abstract: Changes were assessed in serum levels of soluble interleukin-2 receptor (sIL-2R alpha) and soluble intercellular adhesion molecule-1 (sICAM-1), indirect indices of activation of immunological system, in the course of multiple sclerosis (ms). 12 patients (av. age 39.2 +/- 9.4 y.) with the first relapse that fulfilled criteria of clinical probable ms acc. to Poser Committee were included into the study. Blood samples were taken at the beginning of the relapse and then every 2-month periods. Simultaneously, neurological impairment (EDSS scale) was assessed. When the next relapse occurred examination was repeated from the beginning. The total time of observation was between 12 and 18 months. The levels of both soluble molecules were examined with ELISA test. In relapse mean serum levels of sIL-2R alpha and sICAM-1 were significantly elevated in comparison to the results obtained in remission (respectively: p < 0.001 and p = 0.03). Changes in serum level of both soluble molecules during the first 2 months after relapse were significantly higher than in subsequent 2-month periods (p < 0.001). Each relapse was accompanied by elevation of serum levels of sIL-2R alpha and sICAM-1. There was no obtainable correlation between improvement in EDSS scale and changes in sIL-2R alpha level during the whole time of observation. Improvement in EDSS scale was correlated with lowering of sICAM-1 but only during the first two months after relapse.
  
  
  CONCLUSIONS
  Serum level of sIL-2R alpha and sICAM-1 in ms patients during relapse is significantly higher in comparison to the results obtained during remission. Each relapse is accompanied by elevation of sIL-2R alpha and sICAM-1 in serum, during remission serum levels of both molecules do not changed significantly.
