Pregnancy outcome in renal allograft recipients : influence of ciclosporin A

Abstract The outcome of 35 pregnancies in 26 renal allograft recipients is reported. Twenty-four pregnancies in patients treated with prednisolone and azathioprine resulted in 22 live-born infants (one twin pregnancy) and 3 induced abortions on medical indications. Three of the deliveries were preterm, and one of the infants had a birth weight below the 2.5th percentile. Ten patients (11 pregnancies) were treated with ciclosporin A (CsA). These women delivered 5 infants (3 preterm deliveries of whom the birth weight of one infant was below the 5th percentile) and underwent 3 induced (medical indications) and 3 spontaneous abortions. Mean birth weight in the CsA treated group was 2464 g (range 1790–2930 g), and their gestational age varied from 232 to 271 days. No foetal malformations were observed in the two groups. The results may indicate a harmful effect of CsA on pregnancy outcome.
