Safety and Efficacy of in Vitro Fertilization in Women with Systemic Lupus Erythematosus and Antiphospholipid Syndrome

Outcomes of IVF treatments in women with antiphospholipid antibodies or antiphospholipid syndrome

BACKGROUND

Ovulation induction for in vitro fertilization (IVF) may increase intravascular thromboses among patients with antiphospholipid autoantibodies (aPLs) or antiphospholipid syndrome (APS) due to the high estrogen levels. While natural or modified natural IVF treatment cycles (MNC) are sometimes used instead of stimulated cycles with empiric anticoagulant treatment among these infertile patients, their efficacy is unclear.

MATERIALS AND METHODS

A retrospective cohort study including all IVF cycles of patients diagnosed with aPLs or APS in a tertiary, university-affiliated hospital between 2012 and 2022. The outcomes of stimulated cycles with anticoagulants and MNC and natural IVF cycle attempts were compared.

RESULTS

121 oocyte retrievals from 38 women were analyzed: 93 stimulated and 28 MNC or natural IVF cycles. The rates of cycle cancellation (0 % vs. 17.9 %, p < 0.001) and cycles in which no oocytes were retrieved (0 % vs. 43.5 %, p < 0.001) were significantly lower following stimulated cycles vs. natural and MNC. In parallel, positive β-hCG (31.9 % vs. 10.9 %, p = 0.03), clinical pregnancy rate (23.6 % and 3.6 %, p < 0.001) and live birth rates (18.1 % vs. 3.6 %, p = 0.01) were significantly higher following stimulated cycles. No thrombotic events or bleeding occurred in any cycle.

CONCLUSION

Ovarian stimulation for IVF is more effective for successful pregnancy and delivery than natural cycles and MNC and can be safely undertaken in aPLs or APS women undergoing IVF. Rates of complication from hormonal treatment are not increased when treated with LMWH during ovarian stimulation.

Assisted reproductive technologies for women with rheumatic AID

Assisted reproductive technology (ART) procedures are safe for women with rheumatic autoimmune diseases (rAID) when illness is inactive. Medications incompatible with pregnancy should be replaced with alternative pregnancy-compatible medications months before planned ART procedures to allow time to verify the substitute medication's efficacy and tolerability. Medications compatible with pregnancy should be continued, as should anticoagulation (warfarin changed to low-molecular-weight heparin) before pregnancy begins. Protocols that provide details for specific medications are available. All patients with rAID should be screened for diagnosis-relevant organ system damage, and those intending to carry their own pregnancies must be tested for aPL and anti-Ro/La autoantibodies. Patients with organ damage and/or positive tests for aPL and anti-Ro/La should be counseled about fetal and maternal risks, including implications to the child and family of maternal disability or death. Sperm donors with rAID may need to discontinue medications. REI and physicians treating patients with rAID (usually rheumatologists) must work together to plan and accomplish ART.

Glomerular Disease in Women

Gender differences exist in the prevalence of glomerular diseases. Data based on histological diagnosis underestimate the prevalence of preeclampsia, which is almost certainly the commonest glomerular disease in the world, and uniquely gender-specific. Glomerular disease affects fertility via disease activity, the therapeutic use of cyclophosphamide, and underlying chronic kidney disease. Techniques to preserve fertility during chemotherapy and risk minimization of artificial reproductive techniques are considered. The risks, benefits, and effectiveness of different contraceptive methods for women with glomerular disease are outlined. Glomerular disease increases the risk of adverse outcomes in pregnancy, including preeclampsia; yet, diagnosis of preeclampsia is complicated by the presence of hypertension and proteinuria that precede pregnancy. The role of renal biopsy in pregnancy is examined, in addition to the use of emerging angiogenic biomarkers. The safety of drugs prescribed for glomerular disease in relation to reproductive health is detailed. The impact of both gender and pregnancy on long-term prognosis is discussed.
