Abstract
OBJETIVO: avaliar a relação entre os níveis séricos do hormônio gonadotrópico coriônico (beta-hCG) e a medida da espessura endometrial, em pacientes submetidas ao tratamento de gravidez ectópica com metotrexate. MÉTODOS: estudo clínico prospectivo, no qual foram avaliados os títulos do beta-hCG e a maior medida da espessura endometrial no eixo longitudinal uterino por meio da ultra-sonografia transvaginal, em 38 pacientes com gravidez ectópica íntegra, com diâmetro < 3,5 cm, com estabilidade hemodinâmica e aumento dos níveis do beta-hCG num intervalo de 24-48 horas. Todas receberam terapia com dose única de metotrexate (50 mg/m² intra muscular). Foram comparadas as médias dos valores do beta-hCG e da espessura endometrial, das mulheres que evoluíram com sucesso do tratamento e com aquelas que apresentaram insucesso terapêutico. Posteriormente, foi avaliada a diferença entre as médias dos valores séricos do beta-hCG segundo a espessura endometrial (<10,0 mm e >10,0 mm), independente da resposta terapêutica. Para análise estatística foi utilizado o teste t de Student. RESULTADOS: as médias dos valores iniciais do beta-hCG das 28 mulheres que apresentaram resposta terapêutica medicamentosa foi de 1936,2 mUI/ml, significativamente menor do que a média das 10 mulheres sem resposta, 6831,3 mUI/ml (<0,04). Da mesma forma a média da espessura do endométrio foi significativamente menor nas mulheres com resposta d que naquelas sem resposta, 6,4 mm e 11,7mm respectivamente (p<0,01). A média dos valores do beta-hCG das mulheres com espessura endometrial <10,0 mm foi 2008,7 mUI/ml, significativamente menor que daquelas com endométrio >10,0 mm, cuja média foi de 6925,9 mUI/ml. CONCLUSÕES: a medida da espessura endometrial avaliada pela ultra-sonografia sofre influência dos níveis séricos do beta-hCG, se mostrando valiosa como fator orientador adicional na indicação do tratamento medicamentoso com metotrexate na gravidez ectópica íntegra.
OBJECTIVE: to evaluate the correlation between the beta-human chorionic gonadotropin (beta-hCG) serum levels and the measurement of the endometrial thickness, in patients under treatment of ectopic pregnancy with methotrexate. METHODS: a prospective study in which the levels of beta-hCG as well as the largest measurement of the endometrial thickness on the uterine longitudinal axis through transvaginal ultrasound were evaluated at 24-48 h intervals in thirty-eight patients with hemodynamic stability, ectopic pregnancy, diameter <3.5 cm, and increased beta-hCG levels. All the patients got methotrexate in a single-dose therapy (50 mg/m² im). We compared the mean values of beta-hCG and endometrial thickness of cases that evolved successfully versus the poor responders using the Student t-test. Afterwards we analyzed the difference of the beta-hCG mean serum values related to the endometrial thickness(<10.0 mm and >10.0 mm) independently of the response to treatment employing the Student t-test. RESULTS: the mean values of beta-hCG and endometrial thickness in patients with successful treatment (28 cases) were 1936.2 mIU/ml and 6.4 mm, respectively, significanlty lower than the mean values for insuccessful cases: 6831.3 mIU/ml and 11.7 mm, respectively (p<0.05). The mean values of beta-hCG in women with endometrial thickness <10.0 mm were 2008.7 mIU/ml, significantly lower than the ones with endometrium >10.0 mm, whose mean values were 6925.9 mIU/ml (<0.05). CONCLUSIONS: the measurement of the endometrial thickness through ultrasound is under the beta-hCG serum values influence, and it showed to be a valuable additional factor to suggest medical treatment with methotrexate in the non-disrupted ectopic pregnancy.
