OBJECTIVE: To investigate the level of expression of the cytokines interleukin (IL) -8 and IL-6 and their receptors in fallopian tubes with tubal ectopic gestation. DESIGN: Immunohistochemistry (IHC) was used to study the expression of IL-8, CXCR1, CXCR2, IL-6, and IL-6 receptor alpha in fallopian tubes with tubal ectopic gestation in comparison with normal fallopian tubes. SETTING: Hospital. PATIENT(S): We studied fallopian tubes from 50 patients with tubal ectopic gestation and normal fallopian tubes from 25 patients who had hysterectomy and bilateral salpingo-oopherectomy for uterine or ovarian lesions. INTERVENTION(S): The expression of the chemokines/cytokines and their receptors was evaluated by IHC. MAIN OUTCOME MEASURE(S): Level of expression and tissue distribution of the different antigens. RESULT(S): IHC results showed that the expression levels of IL-6 and IL-8, as well as CXCR1, were significantly up-regulated, particularly near the implantation site in fallopian tubes with tubal gestation, while the expression levels of CXCR2 and IL-6Rα were not changed in comparison with normal fallopian tubes. CONCLUSION(S): The results suggest a role for IL-6, IL-8, and CXCR1 in the pathophysiology of tubal ectopic gestation.
