Adenomyosis is a benign gynaecological disease caused by the growth of endometrial tissue in the myometrium that affects approximately 30 % of child-bearing-age women. We evaluated the levels of soluble human leukocyte antigen G (sHLA-G) in the serum of patients with adenomyosis before and after treatment. Serum samples of 34 patients with adenomyosis and 31 patients with uterine fibroids were collected before and after the operation and were analysed for sHLA-G levels byELISAassay. The preoperative levels of serum sHLA-G in the adenomyosis group (28.05 ± 2.466 ng/ml) were significantly higher than those in the uterine fibroid group (18.53 ± 1.435 ng/ml) (P < 0.05). Serum sHLA-G levels in the adenomyosis group showed a decreasing trend at different time points after surgery (28.05 ± 14.38 ng/ml, 18.41 ± 8.34 ng/ml, and 14.45 ± 5.77 ng/ml). Adenomyosis patients who underwent total hysterectomy (n = 20) had a more significant decrease in sHLA-G levels in the early postoperative period (2 days post-operative) than those who underwent partial hysterectomy (n = 14). These results suggest that immunologic dysfunctions may be detected in patients with adenomyosis.
