Up to 3, miscarriages each year in the UK could be prevented thanks to new research into what causes women to lose their baby early in pregnancy.
The study sheds new light on how a cheap experimental treatment works and has led to a formal trial of the drug. Earlier studies suggested that giving steroid drugs to some women who have suffered repeated miscarriages allows them to have a normal pregnancy.
Annie Greenhouse, 35, of York had four miscarriages before being given the experimental treatment. After the fourth one I felt, 'that's it, I can't possibly do this.
But the fifth time she got pregnant she was given the steroid treatment and had a successful pregnancy. Her baby Finlay is now nine months old. It has completely changed my life.
It's wonderful being a mum. It's the most amazing thing ever. Quenby estimates that steroids could help around a third of women who suffer unexplained repeated miscarriages. In total around 18, women miscarry every year in the UK and around half of these miscarriages are unexplained. Her team has investigated how the treatment works in women who have an abnormally high level of "natural killer" NK cells in their uterus. These are a component of the immune system, but in the uterus Quenby has shown that they promote the growth of blood vessels in the womb lining.
The study involved patients who had suffered more than four miscarriages or failed IVF attempts. The women received ultrasound scans to determine blood flow in the uterus plus a smear test to ascertain the level of NK cells. Those with higher levels of NK cells also had higher blood flow and more developed blood vessels in the womb lining. Most of the time this is a positive effect, but in the first few weeks of pregnancy the embryo needs low oxygen conditions to attach to the inner surface of the uterus and form a placenta.
Quenby's hypothesis is that if there are too many blood vessels the area is too well oxygenated and the developing embryo does not implant properly, leading to a miscarriage. The steroid drug works by binding to the NK cells and preventing them from increasing blood vessel growth. To test formally whether the drug is effective, Quenby has begun a pilot double blind clinical trial that will compare the effectiveness of the drugs against a placebo in women who have suffered repeated miscarriages.
The trial — which is funded by the Molton Charitable Foundation — will eventually include 40 patients, although only two have been treated so far. It should lead to a larger trial with hundreds of patients. Quenby pointed out that it was difficult to persuade women who have suffered repeated miscarriages to participate in a trial when they might be given the placebo.
The fertility expert and science populariser Robert Winston welcomed the trial. There is a real need to do what [Quenby has] designed and what she has got funded, which is to do a randomised, properly controlled study," he said.
But he was cautious about the state of the research so far. This article is more than 14 years old. A six-week-old human embryo. Photograph: Getty Images. Reuse this content. Most viewed.
❿- Prednisone during pregnancy prevent miscarriage
In autoantibody-negative pregnant women with habitual miscarriage treated by prednisone and aspirin or aspirin alone, the success rate of live births was Prednisone and aspirin seemed to be as efficient in autoantibody-negative or positive women but better than aspirin alone in autoantibody-negative women.
However, in another study Laskin et al. A double-blind trial is in progress to confirm these results. Two hundred and forty five patients with recurrent abortions were studied for autoantibodies in this paper. The total positive rate of autoantibodies was found to be The presence of antiphospholipid antibodies was in According to the clinical data, these 45 patients were classified into three types: 1 cases with antiphospholipid antibodies; 2 cases with anti-ENA; 3 cases with simple antinuclear antibodies.
The total pregnancy success rate was Excluding anti-ENA cases, the success rate was up to The outcome of pregnancy was usually related to whether the autoantibodies especially LAC turned negative or not.

Fifty of 80 women became pregnant; they were compared with 52 women with idiopathic recurrent miscarriage matched for age and number of miscarriageswho became pregnant without treatment during the same observation period. The median gestational age at birth and median birth weight did not differ between the groups.
The participants were women with a diagnosis of idiopathic recurrent miscarriage. Women were recruited after full investigative screening. Women were randomly allocated to receive either low molecular weight heparin alone, combination treatment consisting of prednisone, aspirin, and progesterone or placebo. Women who were treated with combination therapy had a 4. This difference was not significant. Miscarriage rates were significantly lower in the treated groups compared with placebo.
There were no significant differences in late obstetric complications or neonatal mortality between groups. Both regimens were associated with a good pregnancy outcome.

Hemorheology and coagulative state in 19 patients with autoantibodies revealed hypercoagulative condition.
It suggests that autoantibodies may cause intravascular coagulation leading to recurrent miscarriage. The objective of this study was to assess pregnancy outcome in women with a history of refractory antiphospholipid antibody-associated pregnancy loss es who were treated with early low-dose prednisolone in addition to aspirin and heparin.
Eighteen women with antiphospholipid antibodies who had refractory pregnancy loss es were given prednisolone 10 mg from the time of their positive pregnancy test to 14 weeks' gestation.
The addition of first-trimester low-dose prednisolone to conventional treatment is worthy of further assessment in the management of refractory antiphospholipid antibody-related pregnancy loss esalthough complications remain elevated. The patients with antithyroid autoimmunity were randomly assigned in a blinded manner to an intervention group treated with prednisone administered orally for 4 weeks before IUI or a group given matching placebo.
In the antithyroid antibody-positive group, the pregnancy rate was In the antibody-negative group, the pregnancy rate was 8. The miscarriage rate was not significantly different among the 3 groups. The prevalence of anti-thyroid antibodies among euthyroid, infertile patients was Anti-thyroid antibodies positive patients who did not receive any adjuvant treatment showed significantly poorer ovarian responsiveness to stimulation and IVF results than controls.
Interestingly, the miscarriage rate was significantly higher in all anti-thyroid antibody positive patients, and was unaffected by adjuvant treatments.
An endometrial sample was taken on day 21 of the menstrual cycle. Women with recurrent miscarriage had significantly more uNK than the controls. Altered expression of HLA-G on the extravillous cytotrophoblast has been implicated in the etiology of recurrent miscarriages. Glucocorticoids, dexamethasone and hydrocortisone were examined for their role in modulation of the HLA-G expression. Low level of HLA-G was observed in untreated trophoblast cells obtained from recurrent miscarriage patients as compared with controls.
Upon treatment with glucocorticoids, the expression of HLA-G in these cells was up-regulated in a dose-dependent manner, with no change in cellular proliferation and viability. HLA-G is minimally expressed in cultured trophoblast cells of recurrent miscarriage patients. It can be up-regulated upon exposure with both dexamethasone and hydrocortisone.
Glucocorticoids have the potential to modulate HLA-G expression in vitro, and can be further examined for their therapeutic applicability in recurrent miscarriage. Search this site. Report abuse. Google Sites.
Prednisolone reduces preconceptual endometrial natural killer cells in women with recurrent miscarriage. Fertil Steril.

Multiple studies have shown an association between high density of uterine natural killer cells and recurrent miscarriage. We have shown that. There were 8 first-trimester miscarriages and 1 ectopic pregnancy. gestational diabetes, elevations in blood pressure during pregnancy. Earlier studies suggested that giving steroid drugs to some women who have suffered repeated miscarriages allows them to have a normal pregnancy. This review does not find sufficient evidence to support an increased risk of preterm birth, low birth weight, or preeclampsia following systemic corticosteroid use in pregnancy.Hunt; First-trimester low-dose prednisolone in refractory antiphospholipid antibody—related pregnancy loss. Blood ; 25 : — The objective of this study was to assess pregnancy outcome in women with a history of refractory antiphospholipid antibody—associated pregnancy loss es who were treated with early low-dose prednisolone in addition to aspirin and heparin.
Eighteen women with antiphospholipid antibodies who had refractory pregnancy loss es were given prednisolone 10 mg from the time of their positive pregnancy test to 14 weeks' gestation.
There were 8 first-trimester miscarriages and 1 ectopic pregnancy. There were no fetal deaths after 10 weeks' gestation and no evidence of maternal morbidity. The addition of first-trimester low-dose prednisolone to conventional treatment is worthy of further assessment in the management of refractory antiphospholipid antibody—related pregnancy loss es , although complications remain elevated.
Obstetric antiphospholipid syndrome APS includes recurrent first-trimester loss, later fetal loss, and early delivery because of preeclampsia or placental insufficiency.
In these women, fetal loss may remain high without treatment. Low-dose aspirin is usually given to pregnant women with aPL, and there is conflicting evidence supporting the additional use of heparin in those with previous pregnancy loss es.
Prednisolone in doses of mg daily in addition to aspirin has been used successfully in small numbers of women with APS 7 but was largely disregarded as a treatment option after a randomized controlled trial demonstrated that heparin and aspirin were superior to aspirin and prednisolone, 8 and further studies showed that prednisolone in addition to aspirin conferred no benefit.
Evidence from murine models suggests complement-mediated placental damage in APS pregnancies. The purpose of the present study was to assess the outcome of pregnancies in women with aPL and refractory pregnancy loss es despite the use of aspirin and heparin, with additional prednisolone given in the first trimester. Eighteen women with aPL, seen from August through September , who repeatedly tested positive for aPL and had at least 1 unsuccessful pregnancy while taking both aspirin and heparin, were offered prednisolone 10 mg daily, in addition to our standard anticoagulation, from the time of their positive pregnancy test to 14 weeks of gestation.
Sapporo criteria 1 were used for the definition of APS, because recent guidelines were published in after the study started. Women were seen before pregnancy or in early pregnancy and then at booking weeks , and their progress was reviewed regularly by a multidisciplinary team. Preeclampsia was diagnosed according to international criteria 14 and managed according to unit protocol. Previous obstetric and thrombotic histories and aPL characteristics and autoantibodies are shown in Table 1.
Median age before the pregnancy that was supplemented with prednisolone was 36 years interquartile range years. Before treatment with low-dose prednisolone, there were 93 fetal losses median 4 [IQR Obstetric and thrombotic histories and aPL of women before pregnancy treated with additional prednisolone. There were no congenital abnormalities or late fetal deaths and no evidence of maternal morbidity because of use of low-dose prednisolone.
The present study suggests that women with refractory aPL-related pregnancy losses may have improved pregnancy outcomes with low-dose prednisolone taken until 14 weeks' gestation.
There was considerable early enthusiasm for steroids and aspirin in the management of obstetric APS. However, a randomized controlled trial that compared outcomes after treatment with aspirin plus prednisolone 40 mg or a prophylactic dose of heparin demonstrated no difference in live birth rate but an increased frequency of preterm delivery because of premature rupture of membranes or preeclampsia in the group treated with prednisolone.
A more recent study in women with autoantibodies showed no increase in live birth rate but an increased risk of prematurity and significant side effects, including gestational diabetes, infection, and hypertension, in women treated with prednisolone 0.
Despite the use of aspirin and heparin treatment for women with obstetric APS, birth rates remain suboptimal. Studies demonstrating adverse effects of prednisolone have used doses up to 60 mg. The pathophysiology of obstetric APS is poorly understood, but there is increasing evidence for underlying inflammatory mechanisms. In murine models of APS, anticoagulation alone is insufficient to protect pregnancies, but heparin inhibits activation of complement on trophoblasts in vitro and in vivo and prevents pregnancy loss.
Endometrial natural killer cells have been shown to be associated with recurrent miscarriage. Women with aPL in the present study may have had increased numbers of preconception endometrial natural killer cells contributing to recurrent pregnancy loss, moderated by prednisolone. Placental bed biopsy samples from women with APS have higher concentrations of inflammatory cells, which may also be affected by prednisolone use.
Limitations of the present study include the small number studied and the potential for bias with the use of historical self-controls. However, the results appear encouraging in a very refractory patient population and warrant further investigation. The publication costs of this article were defrayed in part by page charge payment.
