[Functional activity of polymorphonuclear leukocytes in systemic lupus erythematosus and periarteritis nodosa].

The functional activity of polymorphonuclear leukocytes (PMNL) was studied in the test of biochemical luminescence (BCL) in 43 patients including 31 patients with systemic lupus erythematosus (SLE) and 12 with nodular periarteritis (NP). Generation of the active forms of oxygen depended on the activity of the pathological process and the level of the circulating immune complexes (CIC). As established, under the conditions of hyperproductions IC PMNL in patients with SLE and NP preserve a rather high capacity to generate active forms of oxygen into intracellular space that allows one to speak about the role of oxygen radicals in the development of vascular lesions in patients with rheumatic diseases.
