Human chorionic gonadotropin isoforms in the diagnosis of ectopic pregnancy.
BACKGROUND Early diagnosis of ectopic pregnancy uses ultrasound with serial measurements of total human chorionic gonadotropin (hCG). The objective of this study was to explore the possibility that an isolated measurement of hCG isoforms/subunits rather than total hCG could be used as a single test for ectopic pregnancy. METHODS Total and intact hCG, free hCG beta- and alpha-subunits (hCGbeta...
متن کاملEndometrial carcinoma with ectopic human chorionic gonadotropin expression
•Aggressive course and treatment resistance characterize ectopic human chorionic gonadotropin.•Recurrence of endometrial cancer with ectopic hCG was treated with brachytherapy and EMACO.•The serum hCG level can serve as a marker in tumors with ectopic hCG expression.
متن کاملHuman chorionic gonadotropin profile for women with ectopic pregnancy.
OBJECTIVE To analyze serial human chorionic gonadotropin (hCG) levels in women presenting to the emergency department who were ultimately confirmed to have ectopic pregnancies. METHODS Human chorionic gonadotropin levels were obtained over time until definitive diagnosis. To be included, women had to have at least 2 hCG measurements. Human chorionic gonadotropin curves were characterized and ...
متن کاملEctopic production of the isolated beta subunit of human chorionic gonadotropin.
A material similar to the beta subunit of human chorionic gonadotropin (hCG-beta) was detected in serum (300 ng/ml) and tumor extract from a 75-yr-old man with pancreatic adenosquamous carcinoma. This material was indistinguishable from hCG-beta in three different types of radioimmunoassay that displayed widely varying reactions with glycoprotein trophic hormones and their subunits. In gel chro...
متن کاملEctopic human chorionic gonadotropin beta secretion by epithelial tumors and human chorionic gonadotropin beta-induced apoptosis in Kaposi's sarcoma: is there a connection?
Since it was first claimed in 1995 that human chorionic gonadotropin (hCG) inhibits HIV-associated Kaposi's sarcoma (KS), focus has been lost on establishing a credible hypothesis to explain a novel action ascribed to hCG, which is, after all, a pregnancy hormone. After 7 years, no real progress has been made, and there remains no consensus as to which component of hCG preparations is responsib...
