Miscarriage is one of the complications of pregnancy that most concern pregnant women. In fact it is estimated that it is a risk that occurs in 20% of pregnancies, and that in two out of ten cases ends with the death of the baby.

The news is that experts at St. Mary's Hospital in Manchester (England) have found a method of early diagnosis of spontaneous abortion capable of accurately predicting which pregnant women at risk will end up losing their baby.

Until now there was no way to predict the outcome of this threat of miscarriages, so that gynecologists could take ineffective and even potentially harmful measures, such as blood tests, ultrasounds or unnecessary hospital admissions, as one of the authors states. of this work.

To find an alternative to this problem, St Mary researchers followed 112 women at risk of miscarriage, who were between the sixth and tenth week of pregnancy, undergoing various diagnostic tests. The results indicated that there are six factors that have a major impact on the risk of miscarriage: a history of infertility, progesterone levels, human chorionic gonadotropin (hCG), the amount of bleeding, the baby's gestational age and the size of the fetus.

In 20% of pregnancies there is a risk of spontaneous abortion, and in two out of ten cases it ends with the loss of the baby

Combining two of these factors, the amount of bleeding and hCG levels, they came up with what they called Pregnancy viability index (PVI), which could be a useful and effective method to predict pregnancies that may end in an abortion. If we look at the study we see how PVI accounted for 94% of pregnancies that were positive and predicted 77% of those in which a spontaneous abortion took place.

This method will allow opening a greater course of action in this type of case and save the patient unnecessary tests, anticipating in addition to the knowledge of those women who will require psychological help. The next step to give more validity to the PVI will be to try to expand the study with a more significant sample of pregnant women.
