Fertility and pregnancy in rheumatoid arthritis and systemic lupus erythematosus.

BACKGROUND

Rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) are disorders that commonly impact reproductive aged women.

FINDINGS

Both women with RA and SLE have smaller sized families than do controls. In the case of RA factors other than fertility contribute, while in women with SLE there may be diminished ovarian reserve due to cyclophosphamide therapy and advanced maternal age. RA pregnancies can be complicated by preterm birth and small-for-gestational aged infants. SLE pregnancies have higher rates of fetal loss, in particular in those patients with co-existing antiphospholipid syndrome. SLE pregnancies are also more likely to be complicated by pre-eclampsia and hypertension and to result in preterm birth and small-for-gestational aged infants.

CONCLUSION

Appropriate fertility evaluation and careful pregnancy planning with coordinated obstetrical care help ensure better outcomes in these patient populations.
