Recurrent pregnancy loss (RPL) is defined as the consecutive or non-consecutive loss of two or more pregnancies before viability. Established, contributory and postulated causes for RPL include advanced maternal age, anti-TPO antibodies, antiphospholipid antibodies, Müllerian anomalies, parental chromosomal aberrations, inherited thrombophilia and alloimmunity. Recommended investigations include thyroid screening, testing for antiphospholipid antibodies and imaging of the uterus. A thorough reproductive history can guide investigation to include tailored tests (e.g. metabolic and genetic profile). Despite investigation, no cause is found in about 50% of RPL cases.
Thyroid dysfunction should be treated, antiphospholipid antibodies are managed with low-dose aspirin and heparin in a subsequent pregnancy and an intrauterine septum should be resected.
Maternal age and number of prior losses are the major determinants for the prognosis of a subsequent pregnancy. Pregnancies after RPL should be managed as high-risk.
