Early pregnancy ultrasound scans and engagement with an early pregnancy specialist midwife or clinician gives support and reassurance in subsequent pregnancies. Women should be aware of the referral process to the EPAU from 6 weeks if asymptomatic or earlier depending on clinical symptoms or history. Patients can self-refer to EPAU by phone or a referral can be made via Trakare by a clinician.
Pregnancy loss counselling and support services are available via the Miscarriage Association (tel: 01924 200 799). In addition, referral to Clinical Psychology within GGC (tel: 0141 211 4532 (24532)) can be made via BadgerNet (found under MNPI) or via the GP.
For more advanced pregnancy losses, referral to the Child Bereavement Service (tel: 0141 370 4747) within the Royal Hospital for Children in Glasgow may be offered.
Advice and support should be offered on smoking cessation, regular exercise, weight management and limiting alcohol intake. Caffeine intake should be limited to less than 200 mg/day (e.g. approx. 1-2 cups of tea or instant coffee/day, energy drinks should be avoided). In women with BMI≥ 30kg/m2 5mg folic acid daily can be offered pre-conceptually.
Genetic counselling should be offered where there is an abnormal fetal +/- parental karyotype.
Anti-thrombotic prophylaxis is not recommended, to reduce the risk of RM, for either hereditary thrombophilia or in those with unexplained RM (although it may be required to reduce the risk of VTE if risk factors exist).
- Antiphospholipid (APL) Syndrome:
This is defined as pregnancy loss or vascular thrombosis in addition to positive LA or ACA (on two occasions, at least 12 weeks apart)
There is some evidence to support the use of Aspirin plus low molecular weight heparin (LMWH) from positive pregnancy test until at least 34 weeks gestation in those with APL syndrome and a background of RM. If LMWH has not been commenced in early pregnancy, VTE risk assessment should be undertaken, as prophylactic LMWH may still be required for VTE prevention.
Patients with APL may already be on Aspirin out with pregnancy due to the risk of other APLS complications such as stroke.
For those with a positive initial test for APS syndrome who conceive before a second confirmatory test is performed, the risks and benefits of aspirin+/-LMWH in pregnancy should be discussed and treatment offered. The second test should be performed >6weeks after pregnancy for confirmation of the result.
Women with APS treated with Aspirin and LMWH are at risk of complications in all 3 trimesters and warrant obstetric led care.
Levothyroxine should be offered to women with proven hypothyroidism and pregnancy specific levels should be used to monitor levels during pregnancy.
Subclinical hypothyroidism
Treatment with levothyroxine should only be offered if there is true hypothyroidism (i.e. the T4 level is low). Thyroxine supplementation may be considered in those with RM and subclinical hypothyroidism (TSH >4.0ml IU/l with normal T4 levels) to ensure TSH 2.5ml IU/l but the risks must be balanced against the benefits of treatment
Thyroid antibodies
Treatment with thyroxine in women who have thyroid auto antibodies (TPO) but whom remain euthyroid does not improve the pregnancy outcome and should not be offered. These women should have TFT checked during pregnancy.
Women with low vitamin D, should be advised to use supplementation 10micrograms (1000 IU) daily. This can be an over the counter preparation.
Progestogen supplementation in the first trimester of pregnancy may reduce the rate of early pregnancy loss in those with unexplained recurrent miscarriage when there is early pregnancy bleeding in the current pregnancy (Progesterone in Spontaneous Miscarriage, PRISM trial, 2019).
Self-administered progesterone pessaries can be offered in this case.
-
- 1st line : Cyclogest 400mg, administered vaginally twice a day.
- 2nd line Utrogestan 400mg, administered vaginally twice a day.
Progesterone is not thought to improve the pregnancy outcome in those with RM without early pregnancy bleeding (Progesterone in Recurrent Miscarriage, PROMISE, 2015). Women with unexplained RM may choose to take Cyclogest from earlier in the pregnancy in the absence of bleeding but should be informed that this is not evidence based.
- Hysteroscopic resection of a uterine septum or removal of submucosal fibroid or polyps:
This may be discussed and offered in certain circumstances although there is limited evidence that it reduces the rate of RM
- Recurrent second trimester losses:
Recurrent pregnancy loss in the second trimester is associated with cervical weakness and therefore and individualised plan for obstetric led care with serial cervical length scans +/-cervical cerclage is recommended.
- Treatment with the following is not routinely recommended:
-
- Hcg
- Metformin
- Heparin or aspirin for unexplained RPL
- Intralipid
- IV immunoglobulin
- Endometrial scratch
- Pre-implantation genetic screening in conjunction with IVF/ICSI due to the lack of evidence that this improves reproductive outcomes.
