History of progesterone used during pregnancy-Use of progestagens during early pregnancy

Furthermore, most of the assessment of progesterone in pregnancy as it relates to various complications of pregnancy was accomplished from the early s through the early s. In spite of improvements in the accuracy and precision of progesterone assays since that time and a better ability to date pregnancy and establish more accurate gestational ages, very little subsequent work has been accomplished in this area. However, data on the level of progesterone in normal pregnancy, and as it relates to a variety of pregnancy-related complications and features of previous reproductive history has been generated in a study which was conducted from the years through at the Pope Paul VI Institute. Modern means of progesterone assessment with improved accuracy and precision were used along with more precise means of dating the pregnancies. In this study, patients through pregnancies and 8, progesterone levels were studied and statistically evaluated.

Several studies have used Progesterone and related steroids in the attempt to prevent spontaneous miscarriage, and treat recurrent miscarriage. The present paper aims to provide a comprehensive review of the literature on progestagens effects during early pregnancy.

We looked only at the results from randomized controlled trials. We found and analyzed 15 trials on the prevention of recurrent miscarriage and 2 trials on the treatment of miscarriage. The results demonstrated that there is no evidence to support the routine use of progestagens for the treatment of threatened miscarriage. Progesterone Fig. This organ is fundamental for pregnancy maintenance until the placenta syncytiotrophoblast takes over its function at th week of gestation, just after the expression of major histocompatiblity complex antigens is suppressed in extra-embryonic fetal tissue.

Progesterone is an essential hormone in the process of reproduction. Indeed, it induces secretory changes in the lining of the uterus and is essential for a successful implantation of the embryo. Moreover, Progesterone modulates the immune response of the mother to prevent rejection of the embryo, and enhances uterine quiescence and suppresses uterine contractions.

Therefore it is theoretically plausible that P supplementation may reduce the risk of miscarriage in women with a history of recurrent miscarriages. Several studies have used Progesterone and related steroids progestagens- Fig. Although pharmacokinetics and pharmacodynamics features of progestagens have been studied, their use in human pregnancy remains controversial, i. Indeed, progestagens could be administered by three routes: orally, vaginally or intramuscularly.

Oral administration guarantees optimal compliance by patients but shows many disadvantages; this route also results in side effects such as nausea, headache and sleepiness. The vaginal route results in higher concentrations in the uterus but does not reach high and constant blood levels. The drug administered intramuscularly occasionally induces non-septic abscesses, although it is the only route which results in optimal blood levels Whitehead et al. Several reports hypothesized an association between intrauterine exposure to progestagens in the first trimester of pregnancy and genital abnormalities in male and female fetuses.

This was due to the possible up-regulation of androgen receptor operated by pharmacological doses of these steroids. However, maternal safety of progestagens has been reported in different trials. Neonatal safety has been evaluated in only one trial where mothers have been treated with 17 Progesterone. No effects of general health status, external genitalia, and psychomotor development have been reported at follow-up.

Since the paucity of data, ongoing trials are encouraged to include the follow-up of neonates in their study design Mosby, The present paper aims to provide a comprehensive view of the literature on the effects of progestagens during early pregnancy. We describe the effects of progestagens for preventing recurrent miscarriages and managing threatened miscarriage.

Miscarriage is associated with considerable physical and psychological morbidity, particularly in developing countries World Health Organization, Haemorrhage into the decidua basalis and necrotic changes in the tissues adjacent to the bleeding usually accompany abortion; the ovum becomes detached and stimulates uterine contractions that result in expulsion Cunningham, Recurrent miscarriage has been defined as 3 or more consecutive episodes of spontaneous pregnancy losses with the same biological father World Health Organization, Extensive investigation of women involved will fail to find a recognisable cause in up to half of the cases.

Luteal phase defects, immunotolerance derangements, chromosomal anomalies and endocrine disorders are the most common recognisable causes. It is thought, however, that the true incidence of early spontaneous miscarriage may be much higher. Indeed, after implementation of assisted reproduction techniques we are able to detect biochemical pregnancies and therefore to conclude that the rate of early spontaneous miscarriage in the first trimester is higher than expected Everett, Chromosomal anomalies cause at least half of these early miscarriages.

Threatened miscarriage manifests itself through vaginal bleeding, with or without abdominal pain, while the cervix is closed and the fetus is viable inside the uterine cavity. The introduction of ultrasound scans in the management of bleeding in early pregnancy has improved the diagnosis tremendously Hemminki, During the past 50 years several trials investigated the use of progestagens for the prevention of miscarriage.

Actually the therapeutic value of progestagens remains to be established. This might be due to the poor design of the studies which evaluated hormone effectiveness. Moreover, a lot of different aetiologies are associated with threatened miscarriages and heterogeneity of studies has not been accounted for.

We performed a search about all types of progestagens, their applications and potential effects for preventing recurrent miscarriage and for managing miscarriage, regardless of the dose, duration or route of administration compared with placebo, no treatment or other intervention.

All sources of information were read and evaluated by one of the authors GD , and were later independentely checked by another author VV. They included all types of progestagens in the prevention of miscarriage Haas and Ramsey, and for the treatment of threatened miscarriage Wahabi et al. Wahabi et al. The authors included only the trials where the administration of progestagens started before pregnancy and continued during pregnancy. Twenty-nine studies were potentially eligible for inclusion, of these, 15 studies were included after applying the inclusion criteria.

The characteristics of these RCTs are described in Table 1. Haas and Ramsey selected the RCTs or quasi-randomized controlled trials that appeared in 30 journals and the proceedings of major conferences describing all types of progestagens in the treatment of threatened miscarriage.

Participants were all pregnant women, with a history of threatened miscarriage and a confirmed viable pregnancy. Thirty-four studies were potentially eligible for inclusion. Only 2 were included after applying the inclusion criteria Gerhard et al. These two trials met the inclusion criteria and involved 85 participants.

Due to a paucity of data, subgroup analysis for early and late miscarriage, effect of progestagens by type, dose, and route of administration could not be carried out. The overall meta-analysis conducted on the use of progestagens for the treatment of recurrent miscarriages Haas and Ramsey, showed no statistically significant difference in miscarriage rates between progestagens and placebo groups Peto OR 0. The analysis regarding the method of administration also showed no statistically significant difference between progestagens and placebo groups.

No evidence for an effect favouring the use of progestagens in women with recurrent miscarriage was found when compared to placebo Peto OR 1. Four studies Shearman and Garrett, ; Levine, ; Reijnders et al. Only one study compared vaginally administered progestagens with placebo, a second one comparing it with no treatment.

The incidence of recurrent miscarriage was similar in both groups Peto OR 0. The analysis concerning recurrent miscarriage considered 4 trials, of these 2 trials Levine, ; El-Zibdeh, enrolled only women who had suffered three or more miscarriages, 2 others Swyer and Daley, ; Goldzieher, provided separate pregnancy outcome data by number of previous consecutive pregnancy losses. The results showed a reduction in miscarriage in favour of those in the progestagens group Peto OR 0.

This finding however should be approached with caution as numbers are small. Meta-analysis of the effect of vaginal Progesterone on miscarriage when compared to placebo Wahabi et al. Based on scarce data there is no evidence to support the routine use of progestagens for the treatment of threatened miscarriage. Information about potential harms to the mother or child, or both, with the use of progestagens is lacking.

There has been much speculation about progestagens but the results of these meta-analysis show no statistically significant difference between women receiving progestagens for preventing threatened miscarriage or miscarriage when compared to placebo, other treatments or no treatment. Further, larger RCTs investigating potential harms as well as benefits, are urgently needed. A finding of a significantly reduced miscarriage rate in women with a history of recurrent miscarriage was found only in studies that included women with at least three miscarriages.

This finding was obtained with different types of progestagens and therefore deserves further study before entering in clinical practice. National Center for Biotechnology Information , U. Facts Views Vis Obgyn.

A randomised trial of progesterone prophylaxis after midtrimester amniocentesis. Williams obstetrics. Section IX. McGraw-Hill: Reproductive success and failure. Progesterone and Pregnancy. Current opinion. During the menstrual cycle, progesterone levels rise after ovulation to help build and sustain a lining in the uterus.

This lining is where the fertilized egg will implant. The lining will then nourish the growing baby for the early part of the pregnancy. When looking at miscarriage , we know that some women have a lower progesterone level and then miscarry. The question is, did the low progesterone levels cause a miscarriage or did the impending miscarriage cause the low progesterone levels? This is a question that is not always easy to answer.

Though we are trying to figure this out. In trying to help prevent miscarriages, some doctors began prescribing progesterone supplements in pregnancy to many of their patients in order to prevent miscarriage. This drastic approach is probably not the best approach either.

Studies show that progesterone supplements do not really help prevent miscarriage in the average pregnancy, even when there is a threatened miscarriage. There is evidence that progesterone supplementation is imperative in pregnancies that have resulted from certain assisted reproductive technologies ART , like in vitro fertilization IVF. Doctors and women who choose to use progesterone supplements say that this is simply helping the body with a hormone it's already producing.

They believe that there is little risk and only potential benefit to using the progesterone supplements. Those who are concerned and decide not to use the supplements point to the fact that there is no proof that they work. Some doctors are concerned that using progesterone may simply delay a miscarriage that will happen anyway. Because I'd had a previous miscarriage, the doctor suggested that we try the progesterone suppositories," explains Carol.

We didn't find the heartbeat and once I stopped taking the suppositories, I started bleeding out right. I didn't do the suppositories in my next pregnancies because I felt like it was just false hope. The most common form of progesterone treatment is via vaginal suppositories.

These are usually a once a day treatment. Then insert the suppository into the vagina. Some practitioners recommend lying down for thirty to sixty minutes, others say to put it in just before bed. Follow the instructions given to you by your practitioner. On a practical level, wear a pad or panty liner to catch any discharge you have because of the medication.

For women who have had multiple miscarriages, a safe and inexpensive progesterone treatment may increase their chances of completing a pregnancy. In a new study published in the journal Fertility and Sterility , two-thirds of women who used the hormonal supplement before pregnancy successfully delivered babies, despite having had at least two previous pregnancy losses. Progesterone has been shown to help stabilize the inner lining of the uterus called the endometrium, an important factor for healthy embryo development.

Researchers from the University of Illinois at Chicago and Yale University recruited women who had lost at least two early pregnancies, and tested their levels of nCyclinE, a molecular marker for endometrial health.

Those with abnormal levels were then prescribed progesterone supplementation, to be inserted vaginally, twice a day during the second half of their menstrual cycles. The intervention seemed to help. The researchers believe that the progesterone caused the endometrium to secrete more nutrients, which serve as food for an embryo in its first weeks of development.

Women who became pregnant continued taking progesterone until the week mark. Lead author Dr. Mary Stephenson, director of the recurrent pregnancy loss program at the University of Illinois Hospital and Health Sciences, says that women who have suffered multiple pregnancy losses should talk to their doctors about progesterone supplementation. Progesterone can be prescribed in several forms, including creams, capsules and pills that are inserted vaginally with an applicator.

Women can self-administer these treatments, and they are usually covered by insurance, says Dr. However, there are many possible causes of recurrent pregnancy loss, a condition that affects up to one in 20 women.

Before deciding on a treatment option, she cautions, patients should undergo a thorough evaluation to determine what strategies might work for them. In fact, the new research suggests that testing women for nCyclinE and other biomarkers may help doctors determine which patients would benefit from progesterone supplementation. Co-author Dr. Harvey J. Kliman, director of the reproductive and placental research unit in the department of obstetrics, gynecology and reproductive sciences at Yale School of Medicine, invented the patented test for nCyclinE levels used in the study.

Kliman said in a press release. The study was published today in the journal Fertility and Sterility. Stephenson says she is in the early stages of developing a randomized clinical trial, which is needed to validate her early findings and influence any official recommendations for women who have had multiple miscarriages.

In the meantime, those women should talk with their doctors, says Dr. Contact us at editors time. Getty Images.
