Effects of levamisole on the phagocytic function of polymorphonuclear neutrophils from patients with systemic lupus erythematosus.

Incubation of polymorphonuclear (PMN) cells from patients with systemic lupus erythematosus (SLE) with levamisole increased the ability of those cells to reduce nitroblue tetrazolium (NBT). PMN cells from SLE patients treated with levamisole had an increased ability to reduce NBT compared with PMN cells taken before treatment.
