Brief Summary

Recurrent miscarriages (RM) affects 3% of all fertile couples, but remains unexplained in most cases, limiting therapeutic options. Possibly the maternal immune system plays a role in recurrent miscarriage. Prednisolone suppresses the immune system and might enable development of normal pregnancy. In this randomized controlled clinical trial the investigators will study the effect of prednisolone on the live birth rate in patients with RM. Secondary, the tolerability and safety for mother and child and the cost-effectiveness is investigated. In the study one group of pregnant women with RM and gestational age \<7 weeks will receive prednisolone, the other group will receive a placebo. Total use of the medicine during this study is 8 weeks, further care during the study is routinely antenatal care. Subjects will be asked to fill in 4 short questionnaires and will have contact with a research nurse at different time points to gain information on the course of the pregnancy and possible side effects. Results of the study will be implemented in (inter) national guidelines, to effect everyday practice.

Eligibility Criteria

Age18 Years - 40 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • In order to be eligible to participate in this study, a subject must meet all of the following criteria:
  • Unexplained recurrent pregnancy loss: defined as the loss of ≥2 pregnancies, without any known cause for RM (parental chromosomal abnormalities, uterine anomalies, acquired or hereditary thrombophilia, endocrine diseases (such as hypothyroidism or diabetes)).
  • The miscarriages include:
  • all consecutive or non-consecutive pregnancy losses before the 24th week of gestation verified by ultrasonography or uterine curettage and histology
  • non-visualized pregnancies (including biochemical pregnancy losses and/or resolved and treated pregnancies of unknown location), verified by positive urine or serum hCG Ectopic and molar pregnancies are not included
  • Age 18 - 39 years at randomization (likelihood of miscarriages due to chromosomal aberrations is higher when age \> 39 years. Such miscarriages are unlikely to be pre-vented by prednisolone therapy)
  • Conception confirmed by urinary pregnancy test, with estimated gestational age ≤ 7weeks
  • Willing and able to give informed consent in English or Dutch (IC)

You may not qualify if:

  • A potential subject who meets any of the following criteria will be excluded from participation in this study:
  • Any of the following diagnosis for the recurrent miscarriages
  • Antiphospholipid syndrome (lupus anticoagulant and/ or anticardiolipin anti-bodies and/or beta-2 glycoprotein \[IgG or IgM)
  • Congenital uterine abnormalities (as assessed by 2D or 3d ultrasound, hys-terosonography, hysterosalpingogram or hysteroscopy)
  • Abnormal parental karyotype
  • Instable or exacerbation of auto-immune diseases such as diabetes, thyroid disease, inflammatory bowel diseases or SLE
  • Inability to conceive within 1 year of recruitment
  • Current treatment with systemic prednisolone or other immune suppressive medication (for any indication)
  • Previous enrolment in the PREMI trial
  • Enrolment in any other trial that studies the effectiveness of an intervention on RM
  • Contraindications to prednisolone use:
  • Known allergy for prednisolone
  • Acute bacterial infection or parasite infection
  • Active COVID infection
  • Systemic sclerosis
  • +8 more criteria

Data Sharing

IPD Sharing
Will share

Possibly various covariates among women with RM contribute to the effect of prednisolone on the live birth rate. To further study the effect of prednisolone in predefined subgroups we aim to conduct a individual participant data meta-analysis. These subgroups include groups defined on female age, number of previous miscarriages, antinuclear antibodies positivity and TPO antibodies positivity
