| Popis: | Introduction: Recent reports consider endometriosis to be an immunological disorder, thus suggesting potential efficacy of immunomodulators for its treatment. The aim of this study was to assess the effects of oral administration of pentoxifylline on endometriosis-like lesions in a heterologous mice model. Study Design: Human endometrial tissue obtained from women (n = 5) undergoing surgery for benign conditions was implanted in nude female mice (n = 30). The animals were distributed into 3 experimental groups receiving: saline 0.1 mL/d (control, group I); pentoxifylline 100 mg/kg/d (group 2), and pentoxifylline 200 mg/kg/d (group 3). After 28 days, the number of implants and the total volume of surgically extracted tissue were recorded. Immunohistochemical analysis was performed to assess the area of endometriosis and vascularization of endometriosis-like lesions. Cytokine levels in peritoneal fluid samples were measured. Results: Macroscopic quantification showed a trend to dose-dependent reduction in the number of the endometriosis-like lesions after 28 days. The volume was significantly reduced in group 3 versus group 2 and controls (399.10 ± 120.68 mm3 vs 276.75 ±94.30 mm3 and 145.33 ± 38.20 mm3, respectively; P = .04). Similarly, the mean area of endometriosis was significantly lower in group 3 (0.12 ± 0.08 mm2) versus group 2 (1.35 ± 0.43 mm2) and control (2.84 ± 0.60 mm2; P = .001). Vascularization and cytokine levels were also reduced posttreatment. Conclusion: Our results suggest that the oral administration of pentoxifylline may be an alternative to current therapies for endometriosis. Nonetheless, further studies are required. |
