          Abstract

          OBJETIVOS: relatos da literatura mostram que não há dados conclusivos sobre a associação entre a endometriose e as concentrações de hormônios envolvidos no controle da reprodução. Este estudo foi realizado para determinar as concentrações de FSH, LH, estradiol (E), progesterona (P) e histamina (Hi) no soro, no fluido peritoneal e no fluido folicular de mulheres com e sem endometriose. MÉTODOS: a extensão da doença foi estadiada de acordo com a American Fertility Society classification (1997). Para a coleta de soro e de fluido peritoneal foram selecionadas 28 mulheres com endometriose submetidas à laparoscopia diagnóstica (18 mulheres inférteis com endometriose I-II e dez mulheres inférteis com endometriose III-IV). Para o grupo controle, foram selecionadas 21 mulheres férteis submetidas à laparoscopia para esterilização tubárea. O fluido folicular foi obtido de 39 mulheres inférteis submetidas a fertilização in vitro (21 mulheres com endometriose e 18 mulheres sem endometriose). RESULTADOS: as concentrações de FSH e LH no soro, no fluido peritoneal e no fluido folicular não diferiram significativamente entre os grupos. As concentrações de E e P no fluido peritoneal foram significativamente mais baixas em mulheres inférteis com endometriose (E: 154,2±15,3 para estágios I-II e 89,3±9,8 ng/mL para estágios III-IV; P: 11,2±1,5 para estágios I-II e 7,6±0,8 ng/mL para estágios III-IV) em comparação com mulheres controle (E: 289,1±30,1; P: 32,8±4,1 ng/mL) (Testes de Kruskal-Wallis/Dunn; p<0,05). No soro, as concentrações de E e P seguiram o mesmo padrão. No fluido folicular, as concentrações de E e Hi foram significativamente mais baixas em mulheres com endometriose (E: 97,4±11,1 ng/mL; Hi: 6,6±0,9 ng/mL) em comparação com mulheres sem endometriose (E: 237,5±28,5 pg/mL; Hi: 13,8±1,3 ng/mL), enquanto os níveis de P não revelaram diferença significativa entre os grupos (teste t de Student; p<0,05). CONCLUSÕES: nossos resultados indicam disfunção ovariana em mulheres com endometriose, com redução nas concentrações de estradiol, progesterona e histamina, o que pode contribuir para a subfertilidade freqüentemente associada à doença.

          PURPOSE: literature reports show that there are no conclusive data about the association between endometriosis and the concentrations of hormones involved in the control of reproduction. Thus, the present study was undertaken to determine FSH, LH, estradiol (E), progesterone (P), and histamine (Hi) concentrations in serum, peritoneal fluid and follicular fluid of women with and without endometriosis. METHODS: the extent of the disease was staged according to the revised American Fertility Society classification (1997). For the collection of serum and peritoneal fluid, 28 women with endometriosis undergoing diagnostic laparoscopy were selected (18 infertile women with endometriosis I-II and ten infertile women with endometriosis III-IV). For the control group, 21 fertile women undergoing laparoscopy for tubal sterilization were selected. Follicular fluid was obtained from 39 infertile women undergoing in vitro fertilization (21 women with endometriosis and 18 women without endometriosis). RESULTS: FSH and LH levels in serum, peritoneal fluid and follicular fluid did not differ significantly between groups. On the other hand, E and P concentrations in the peritoneal fluid were significantly lower in infertile women with endometriosis (E: 154.2±15.3 for stages I-II and 89.3 ng/mL±9.8 ng/mL for stages III-IV; P: 11.2±1.5 for stages I-II and 7.6 ng/mL±0.8 for stages III-IV) in comparison with control women (E: 289.1 ng/mL±30.1; P: 32.8±4.1 ng/mL) (Kruskal-Wallis/Dunn tests; p<0.05). In serum, estradiol and progesterone concentrations followed the same pattern. In the follicular fluid, E and Hi concentrations were significantly lower in women with endometriosis (E: 97.4±11.1 pg/mL; Hi: 6.6±0.9 ng/mL) in comparison to women without endometriosis (E: 237.5±28.5 pg/mL; Hi: 13.8±1.3 ng/mL) (Student t-test; p<0.05), while progesterone levels revealed no significant difference between groups. CONCLUSIONS: our results indicate ovary dysfunction in women with endometriosis, with reduction on E, P and Hi concentrations, which may contribute to the subfertility often associated with the disease.

            Antiangiogenic agents are effective inhibitors of endometriosis.

            Endometriosis is a disease in which the lining of the uterus (endometrium), shed at the time of menstruation, becomes established at sites such as the peritoneum and ovaries. These explants develop a rich blood supply that enables them to survive and grow. We hypothesized that inhibitors of angiogenesis would prevent this growth by disrupting sensitive vessels supplying endometriotic lesions. Vessels sensitive to angiogenic antagonism have few associations with pericyte cells. The vessels supplying human endometriotic lesions were immunohistochemically characterized and found to be predominantly pericyte free. A model in which human endometrium is implanted into nude mice was used to test the effects of two antagonists of the angiogenic growth factor, vascular endothelial cell growth factor A. Soluble truncated receptor (flt-1; P = 0.002) and an affinity-purified antibody to human vascular endothelial cell growth factor A (P = 0.03) significantly inhibited the growth of nude mouse explants. Pericyte-free vessels were shown to supply endometrial lesions in nude mice and were disrupted in lesions taken from soluble flt-1-treated mice. In summary, antiangiogenic agents inhibited the growth of explants in an in vivo model of endometriosis by disrupting the vascular supply, and this effect is likely to apply to the human disease. These findings suggest that antiangiogenic agents may provide a novel therapeutic approach for the treatment of endometriosis.
