Molar pregnancy is the condition caused due to an error in the process of fertilization . This also results in abnormally higher denseness of hCG hormone .
What Is Molar Pregnancy hCG?
A hCG hormone is higher during pregnancy , but the level is even higher during consummate molar pregnancy . Due to such higher level , the testing gimmick sometime give a sham negative result . The layer of hCG is comparatively lower in partial molar pregnancy as compared to complete molar pregnancy .
hCG ( Human Chorionic Gonadotrophin ) hormone is release by the placenta on concept i.e. when the fertilized egg is attached to the rampart , the secretion of this hormone is initiate by the placenta . It is find in the urine as early as six twenty-four hours after creation and can be measured through gestation testing strips . trial of this hormone can be done in both blood line and urine . The level of this hormone is evaluated during pregnancy as well as to name gestational trophoblastic diseases . Various forms of his hormone are present in the consistence . This includes chip hCG , intact hCG , hyperglycosylated hCG , and free beta hCG . Out of these pattern , the most analyzed form is beta - hCG . eminent tier of his internal secretion is recover during molar pregnancy .
However , this does not mean that a eminent level of hCG always means a molar gestation . It also does not mean that every molar pregnancy has abnormal level of hCG . A all over molar pregnancy can be diagnose through a high level of hCG along with other parameters as the tier in the term is abruptly high and is more than 100000 IU / ml . However , diagnosing becomes unmanageable in case of partial molar pregnancy as the range of this hormone is blanket and may also within the range of normal pregnancy .
Thus , the fond molar gestation condition is diagnose by accessing histological parametric quantity . However , it should also keep in mind that the symptomatic method acting sometimes give false negatively charged results for hCG uncompleted molar pregnancy due to the crotchet effect . claw impression is due to the oversaturation of signalize antibody in the examination machine .
Molar Pregnancy
Generally , the eggs is free by the ovary and the sperm fertilizes the egg . This fecundate egg attache to the placenta and the growth of fetus strike berth . The grade of hCG is increase as it is secrete by placenta after innovation . This is caused due to the error occurred during dressing . The error may be the fertilization of a sperm cell with an egg which does not contain DNA . This lead in a fertilized bollock with no foetus . The other wrongdoing may occur if two sperms fertilize an nut resulting in the combination of chromosomes of all the three haploid cadre . This result in an unviable foetus with wicked birth defects .
Pathophysiology Of Molar Pregnancy
Molar pregnancy , also known as hydatidiform mole , is characterized by the engagement of placental villus . The disease is a part of a larger disease known as gestational trophoblastic disease . The disease has a high rate of favorable forecast due to two important grounds . First , the identification and diagnosis of the disease can be accurately done . hCG is an important marker for this disease . Second , the disease is extremely reactive to drugs such as methotrexate . A molar pregnancy can be divided into two character on the basis of characteristics of the diseased tissues .
Complete Molar Pregnancy . In the complete molar pregnancy , the sperms feed with an empty nut . This means that there is no enate substance present in the bollock . The eggs does not have deoxyribonucleic acid . In this case , the father ’s chromosome are duplicated as there are no female parent chromosomes . These pregnancies only have the placental part and do not have a fetus . The assiduity of hCG hormone increases due to the growth of the placenta . Ultrasoundclearly indicates the absence seizure of foetus and the growth of the placenta .
Partial Molar Pregnancy . In a partial molar gestation , there is a growth of uncompleted foetus and placenta . The fetus take shape in fond molar pregnancy has grave birth blemish . It is due to the fact that partial molar pregnancy is caused when two sperms fertilize the egg . Thus the number of chromosome in the fertilized nut is 69 as compared to 46 in the normal fertilized ballock .
