Abstract

Activated B cells have recently been shown to produce soluble CD23 from their membranes. The serum-soluble CD23 concentration in 21 patients with pelvic pain diagnosed as having endometriosis and confirmed by histology, and in 18 patients without pelvic pain, who had a normal pelvis during laparoscopic sterilization, was studied by chemiluminescent enzyme-linked immunosorbent assay. The endometriosis patients were randomized to 3 months of either danazol or leuprolide acetate injection. Serum was taken before and after 3 months of therapy. The serum-soluble CD23 concentration was significantly elevated in patients with endometriosis when compared with the controls (P 0.05). The serum concentration of soluble CD23 decreased significantly on treatment with danazol but not leuprolide acetate (P < 0.05). We conclude that the elevation of soluble CD23 in patients with endometriosis suggests that there is activation of B cells, which respond to danazol but not leuprolide acetate injection.
