Background. Caesarean scar pregnancy (CSP) is a rare ectopic pregnancy associated with life-threatening complications. To date, no therapeutic protocols have been established. Sono-guided local methotrexate (MTX) injection is a relatively easy and low-invasive treatment. Additional systemic MTX is sometimes needed for CSP cases, especially when β-subunit human chorionic gonadotropin (β-hCG) lev...
Background and Objectives: GTN is a general term for an extensive range of malignant trophoblastic diseases including invasive mole, choriocarcinoma, epithelioid trophoblastic tumors and placental site trophoblastic tumors. The aim of this study was to predict the risk of GTN in patients with molar pregnancy in Tehran. Methods: All cases with partial and complete mole with a record of at lea...
β -human chorionic gonadotropin (HCG) level is not a reliable marker for early identification of persistent gestational trophoblastic neoplasia (GTN) after evacuation of hydatidiform mole. Thus, this study was conducted to evaluate β -HCG regression after evacuation as a predictive factor of malignant GTN in complete molar pregnancy. Methods. In this cross-sectional study, we evaluated a total ...
Background and Objective: Hyperemesis gravidarum (HG) is defined as vomiting sufficiently severe to produce weight loss, dehydration, electrolyte abnormalities. Interleukin-6 (IL-6), a pro-inflammatory and trophoblast-derived cytokine has ability to induce trophoblasts to secrete human chorionic gonadotropin (hCG). The purpose of our study was to assay the level of IL-6 and β-hCG in serum of pr...
This is a case report of a twin pregnancy with one fetus and a coexistent mole diagnosed at 13 weeks. After thorough counseling, the pregnancy was continued as per the patient's desire. The pregnancy was closely monitored with serial S β hCG, ultrasound for fetal growth, size of molar sac, and theca lutein cysts, which gradually decreased in size during the second trimester of pregnancy. An eme...
Human chorionic gonadotropin (hCG), a heterodimeric hormone consisting of an alpha (a) and a beta (β) subunit, is used as a marker for the diagnosis of pregnancy, congenital defects, and choriocarcinoma. After excluding the common causes of elevated serum hCG, laboratory identification of false-positive or true results assists in guiding clinical management. Options include testing urine for hC...
Human chorionic gonadotropin (hCG) displays a major role in pregnancy initiation and progression and is involved in trophoblast differentiation and fusion. However, the site and the type of dimeric hCG production during the first trimester of pregnancy is poorly known. At that time, trophoblastic plugs present in the uterine arteries disappear, allowing unrestricted flow of maternal blood to th...
سابقه و هدف: از آنجا که توافق کلی درباره بهترین روش ارزیابی ختم حاملگی در سه ماهه اول با میزوپروستول وجود ندارد، مطالعه حاضر به منظور مقایسه سونوگرافی و β hcg در ارزیابی کامل بودن سقط در بیماران بستری شده در بیمارستان شبیه خوانی کاشان در سال 1389 انجام شد. مواد و روش ها: در این مطالعه 133 بیمار که سقط فراموش شده داشته یا تخمک پوچ آنها با استفاده از سونوگرافی تایید گردیده و ساک حاملگی آنان حداکث...
BACKGROUND Hyperglycosylated human chorionic gonadotropin (hCG-h) contains larger and more complex carbohydrate chains than regular human chorionic gonadotropin (hCG). hCG-h is thought to be the major form of hCG produced by testicular cancers and it has been suggested to play a key role in tumor invasion, but studies on hCG-h in testicular cancer are limited. We studied whether serum hCG is hy...
اهداف: سرطان تخمدان شایع ترین بدخیمی کشنده دستگاه تناسلی زنان است که در اکثریت موارد در مراحل پیشرفته تشخیص داده می شود. هدف اصلی از این مطالعه مقایسه سطح سرمی نشانگرهای توموری β-hcg، کلسیم، فسفر و فعالیت آنزیم آلکالن فسفاتاز در افراد سالم و مبتلا به سرطان تخمدان و بررسی امکان استفاده از فاکتورهای فوق به عنوان مارکر سرطان تخمدان بود. مواد و روش ها: مطالعه مورد- شاهدی حاضر در مراجعه کنندگان به ب...
