RESUMO

BACKGROUND: To investigate the value of a single determination of hyperglycosylated hCG (hCG-H) for predicting the clinical outcome of patients with threatened abortion in the first trimester of pregnancy. METHODS: Prospective study performed on 86 consecutively selected women with a diagnosis of threatened abortion and viable intrauterine pregnancy in the first trimester of pregnancy, conducted in two tertiary care hospitals. All patients underwent a single blood sample to determine hCG-H and total hCG serum levels and a transvaginal ultra-sound 12-24 hours after diagnosis. Patients were monitored to determine whether the outcome was a miscarriage before the 20th week of pregnancy. RESULTS: Forty-three women (50%) had a miscarriage during the follow-up. We observed a very high correlation between hCG-H and total hCG (r = 0.91, p < 0.001). Median hCG-H and total hCG from pregnancies with normal outcome was significantly higher than those ending in abortion. hCG-H and total hCG were very similar predictors of pregnancy outcomes (AUC: 0.90 and 0.89, respectively). The ratio hCG-H / total hCG was a poor predictor (AUC: 0.64). CONCLUSION: A single hCG-H assay is helpful for predicting pregnancy outcomes in women with first trimester threatened abortion and viable or potentially viable pregnancy at the time of presentation. However, hCG-H is not a better predictor than total hCG


FUNDAMENTO: Investigar el valor de una única determinación de hCG hiperglicosilada (hCG-H) para predecir el resultado clínico de pacientes con amenaza de aborto en el primer trimestre del embarazo. MÉTODOS: Estudio prospectivo realizado en 86 mujeres, seleccionadas consecutivamente, con diagnóstico de amenaza de aborto y embarazo intrauterino viable en el primer trimestre de embarazo, realizado en dos hospitales de tercer nivel. A todas las pacientes se les realizó una única extracción sanguínea para determinar los niveles séricos de hCG-H y hCG total, y una ecografía transvaginal 12-24 horas después del episodio de sangrado. Se realizó seguimiento de las pacientes para determinar si el resultado fue un aborto espontáneo antes de la semana 20 de embarazo. RESULTADOS: Cuarenta y tres mujeres (50%) sufrieron un aborto espontáneo durante el seguimiento. Se observó una correlación muy alta entre hCG-H y hCG total (r = 0,91, p < 0,001). La mediana de hCG-H y hCG total de los embarazos con resultado normal fue significativamente mayor que la de aquellos que terminaron en aborto. La hCG-H y la hCG total fueron predictores muy similares del resultado del embarazo (AUC: 0,90 y 0,89, respectivamente). La relación hCG-H / hCG total fue un mal predictor (AUC: 0,64). CONCLUSIÓN: La determinación única de hCG-H es útil para predecir el resultado del embarazo en mujeres con amenaza de aborto en el primer trimestre y embarazo viable en el momento de la presentación clínica. Sin embargo, la hCG-H no es mejor predictor que la hCG total
