[Sarcoidosis and pregnancy. A retrospective study of 11 cases]

To analyze the evolutive profile of sarcoidosis together with reciprocal interactions between pregnancy and sarcoidosis.

All events that occurred during pregnancy in 11 women presenting with sarcoidosis were analyzed. Histological confirmation was obtained for the 11 cases. For all pregnancies were analyzed the course of both sarcoidosis and pregnancy, and the influence of pregnancy on the disease evolution.

Among 33 pregnancies, 23 led to the birth of healthy fetuses (five spontaneous abortions, four voluntary abortions, and one therapeutic abortion). The major event was fetal hypotrophy in six cases. Three of them occurred during pregnancy in prednisone-treated patients with active sarcoidosis. No relapse of cured sarcoidosis or further evolution of sarcoidosis that was inactivated as of the beginning of pregnancy were observed. The course of active sarcoidosis varied, as improvement (one case), worsening (two cases) and stabilization (two cases) were observed. During the first year of follow-up after delivery, four relapses and, in two cases, preliminary signs of the disease were observed.

Apart from the hypothetical but not definite risk of hypotrophy, no negative interaction between sarcoidosis and pregnancy could be established. Pregnancy does not seem to interfere with the course of sarcoidosis. Considering the risk of relapse after delivery, pregnant women presenting with sarcoidosis should benefit from clinical and radiological follow-up.
