Gold therapy in women planning pregnancy: outcomes in one center.

OBJECTIVE

To review the experience and outcome of pregnancies in women taking gold while planning pregnancy.

METHODS

We undertook a chart review of patients attending for gold injection and monitoring between January 1992 and April 2006. For women who became pregnant while being followed taking gold therapy, we extracted demographic, treatment, and disease activity data, information regarding pregnancy complications, outcome, and postpartum course. For details missing from the clinic records, patients were interviewed by the clinic nurse.

RESULTS

Fourteen women experienced 20 pregnancies while being followed in the gold monitoring clinic. Mean age at the time of conception was 34.5 years (range 24-41), disease duration 8.5 years (1-16). Rheumatoid factor was positive in 9 of 14 women. Duration taking gold prior to conception was < 12 months in 7 pregnancies, 13-24 months in 4, 25-34 months in 2, and 2-10 years in 7 pregnancies. Four women continued taking gold until delivery. The rest of the women discontinued gold when they knew they were pregnant, with the exception of one who held her gold 4 weeks prior to conception. There were 5 spontaneous abortions in the first trimester; included were 2 spontaneous abortions in a woman with known Robertsonian chromosomal translocation. Sixteen babies were healthy including a pair of twins. One baby was born with weakness of one extraocular muscle requiring surgery; one had blocked tear ducts at birth. Rheumatoid arthritis (RA) flared during 3/15 completed pregnancies and postpartum and post-spontaneous abortion in 18/20 pregnancies.

CONCLUSION

Our clinic experience and the published literature support the current practice that in patients with RA, gold may still be considered a treatment option in women planning pregnancy.
