Brief Summary

Threatened miscarriage is manifested by vaginal bleeding, with or without abdominal pain, while the cervix is closed and the fetus is viable and inside the uterine cavity. Threatened miscarriage is a common complication of pregnancy occurring in 20% of all clinically recognized pregnancies and about half of these will eventually result in pregnancy loss. The goal of this two by two factorial, placebo controlled randomized trial is to determine that two oral medications and their combination, will mostly likely result in live birth in women with threatened miscarriage. We will evaluate the efficacy and safety of Chinese herbal medicine (New "Shoutai Wan", NSTW) and/or oral micronized progesterone (OP) for treating threatened miscarriage in this trial. Our primary outcome of this trial is live birth. We hypothesize that: 1. treatment with NSTW plus OP or OP placebo is more likely to result in live birth than NSTW placebo plus OP or placebo; 2. treatment with OP plus NSTW or NSTW placebo is more likely to result in live birth than OP placebo plus NSTW or NSTW placebo; 3. treatment with combination of NSTW and OP is more likely to result in live birth than combination of NSTW placebo and OP placebo.

Detailed Description

The causes of spontaneous miscarriage are diverse and comprise chromosomal, genetic, anatomical, immunological, hormonal, infectious and psychological factors, the other factors contribute to an increased risk include advancing paternal and maternal age and mothers with systemic diseases, such as diabetes or thyroid dysfunction. The incidence is difficult to determine precisely because it occurs very early during a pregnancy and almost 30% of early pregnancy may go unrecognized; the pathogenesis of pregnancy loss in this condition is still remains obscure. Compared with healthy women, the women with threatened miscarriage were found not only to have increased rate of antepartum haemorrhage, prelabour rupture of the membranes, preterm delivery, and intrauterine growth restriction, but also suffer from significant psychological impairment including considerable anxiety and stress, depression, sleep disturbances, anger, and marital disturbances.

To date, therapies have limited effectiveness in treating threatened miscarriage and are empirical. Bed rest does not prevent pregnancy loss. Acetaminophen may have some effects on relieving pain only. The most commonly used prescription medication was human chorionic gonadotropin (hCG), maintaining the luteotrophic effects to support continued secretion of estrogen and progesterone, but it's beneficial effects still cannot be verified. Progesterone is another most commonly used standard medication, maintaining the endometrial proliferation and preventing poor decidualization. A number of recent studies in women with threatened miscarriage shown a reduction in pregnancy loss with progesterone treatment. But progestogens are a group of hormones, including both the natural female sex hormone progesterone and the synthetic forms. Micronized progesterone is a kind of progesterone; it is structurally and pharmacologically very similar to natural progesterone and has good oral bioavailability. It is especially suitable for women with threatened miscarriage as it does not have androgenic or oestrogenic effects on the foetus. A recent review of maternal use of micronized progesterone during pregnancy also found no evidence for an increased risk of congenital malformations. However it may only be suitable to treat women with threatened miscarriage who have low progesterone levels due to corpus luteum deficiency at the first trimester of pregnancy. There is no evidence to show the beneficial effects of progesterone to treat threatened miscarriage due to others factors. At the same time, progesterone treatment is also expensive. New or adjuvant treatments that are suitable, readily accessible, affordable, and safe are needed to treat women with threatened miscarriage.
