[Hormone therapy of spontaneous abortion. Our experience with treatment with Gravibinan].

The results of the treatment of 151 pregnancies with threatened and/or habitual abortions by using high hormonal dosages (Gravibinan "Alkaloid") are presented. Eight pregnancies were in primigravidas, the remaining 143 patients having previously had 47 interruptions of pregnancy, 66 deliveries, and 313 spontaneous abortions. Disregarding artificial abortions in 379 previous pregnancies there were 313 or 82.5 per cent spontaneous abortions. The treatment was performed by i. m. applications of Gravibinan, during the first week every two days, during the following two weeks every three days, and until the accomplished 16 weeks of pregnancy every five days. Besides hormonal therapy, all patients were on bed rest; in the following course of pregnancy tocolysis and in the case of opened cervix the cerclage cervicis were performed. The vitality of the ovum and the fetus, as well as the efficacy of the treatment were evaluated by clinical findings, HCG and estriol urinary eliminations, and by ultrasonography. Out of 151 treated pregnancies, 21 (13.91%) resulted in early abotion, 17 (11.26%) in mid-trimester abortion, 6 (3.97%) in pre-term, and 107 (70.86%) in term deliveries. There were two (1.77%) perinatally dead premature infants. HCG urinary eliminations were significantly lower in pregnancies resulting is missed abortion or first-trimenon miscarriage, whereas no difference was established between pregnancies resulting in delivery or mid-trimester abortion. The authors recommend hormonal treatment in early threatening and/or habitual abortions by administering high dosages of estrogens and gestagens. Such a treatment stimulates secretory transformation of the endometrium at the beginning of pregnancy, and this allows early placentation and the uterine growth with a simultaneous quiescence of the myometrium, which, in turn, makes the growth of the ovum possible. The authors stress the importance of a complex procedure in the establishment of the etiology and in the treatment of spontaneous and/or habiutal abortion.
