RESUMEN

We compared post-abortion metrorrhagia in 185 women who used the mifepristone (600 mg) plus sulprostone (250 micrograms) drug combination and in 196 women who underwent vacuum aspiration. The patients were monitored for a 2 week period, with haemoglobin being measured on the day of the abortion and 2 weeks later. The women who had used the drug combination experienced a mean fall of 0.7 g/dl in haemoglobin (36% lost > 1 g/dl and 8% > 2 g/dl); haemoglobin concentrations remained stable in women who had had vacuum aspiration.


PIP: A comparative study of 381 French women undergoing first-trimester induced abortion by either RU-486 (600 mg) in combination with sulprostone (250 mcg) or vacuum aspiration found that the former method is associated with moderate but significant blood loss in the post-abortion period. Abortion seekers were given a choice of method; the 185 women in the drug-induced abortion group were significantly more likely than their surgical abortion counterparts to be employed in managerial positions and to have a university education. At the 14-day post-abortion follow-up, a mean fall in hemoglobin level of 0.71 g/dl from baseline was recorded among women in the RU-486 group; 36% lost more than 1 g/dl and 8% lost more than 2 g/dl. In the vacuum aspiration group, there was no change in hemoglobin concentrations. Multivariate analysis indicated that the variation in hemoglobin levels was significantly associated with abortion method (p 0.0001) but not with age, race, socioeconomic status, parity, or duration of pregnancy. Since women in developing countries tend to have low hemoglobin levels, especially small iron reserves, the issue of post-abortion metrorrhagia should be given careful consideration before the drug-induced abortion method is introduced.

RESUMEN

Termination of early pregnancy (less than 49 days of amenorrhea) was induced in 75 patients with the combination of the antigestagen mifepristone and a prostaglandin analogue, meteneprost. After 48 h a single oral dose of 600 mg of mifepristone was followed by a 10 mg meteneprost vaginal pessary. Pregnancy was confirmed by clinical and ultrasound examinations and plasma HCG assessment. Complete abortion occurred in 72 patients (96%) and the three others required a surgical uterine aspiration. Bleeding continued for 4 to 12 days (mean = 8). Uterine pain and side effects occurred during the 3 h following the use of prostaglandin. Only minor analgesic were required in 30 patients. The combination of mifepristone and meteneprost is a safe and effective method to terminate an early pregnancy.


PIP: Termination of early pregnancy (49 days of amenorrhea) was induced in 75 patients with the combination of the antigestagen mifepristone and a prostaglandin (PG) analogue, meteneprost. After 48 hours, a single oral dose of 600 mg mifepristone was followed by a 10 mg meteneprost vaginal pessary. Pregnancy was confirmed by clinical and ultrasound examinations and plasma hCG assessment. Complete abortion occurred in 72 patients (96%) and the 3 others required a surgical uterine aspiration. Bleeding continued for 4-12 days (mean=8). Uterine pain and side effects occurred during the 3 hours following the use of PG; only minor analgesics were required in 30 patients. The combination of mifepristone and meteneprost is a safe and effective method of terminating and early pregnancy.

RESUMEN

Mifepristone (RU 486) is a new steroid which is a progesterone antagonist and which is able to interrupt early pregnancy without any major side-effects. The purpose of our study was to evaluate the clinical effect of a single oral dose of 600 mg on early pregnancy. The study included 150 healthy women applying for a legal abortion with an amenorrhea of no more than 42 days. Pregnancy was confirmed by clinical and ultrasound examination and plasma HCG assessment. Success was assumed by repeating these exams on the eighth day. 131 patients had a complete abortion (87.3%), with a very few side-effects. Only two patients needed curettage for heavy bleeding. Mifepristone is able to terminate early pregnancy by an easy ambulatory method under medical supervision.


PIP: Mifepristone, a new steroid and progesterone antagonist, was administered to 150 women with amenorrhea of less than 42 days who were seeking abortions. A single dose of 600 mg was given to each woman to take orally at home in the evening. The clinical events that should occur were explained to the women and they were given a permanent emergency telephone number. Follow-up visits were scheduled on the 8th day, when clinical tests, ultrasound examinations, and blood sampling were performed. Success was assumed if vaginal bleeding occurred between days 3-8, ultrasonic examination confirmed uterine vacuity, and a decrease in plasma HCG level was observed. A total of 131 of the 150 women were considered to have had complete abortion. The remaining 19 women included 14 developing pregnancies, 2 curettages for heavy bleeding, and 1 extrauterine pregnancy. Daily amount and duration of bleeding were compared to abundant menstruation. Only 2 women reported heavy bleeding leading to curettage. Only 16 women had hemoglobin levels low enough to justify iron therapy. None needed a transfusion. Several other side effects were reported--uterine contractions and pelvic pain, transient asthenia, and slight nausea. All biological tests remained in the normal range. Having shown a success rate of 87.3% and with mild side effects, Mifepristone appears to be a simple and safe agent for termination of early pregnancy, and a good alternative to surgical abortion.

RESUMEN

Hemolytic anemia with red cell fragmentation, poikilocytosis, and elliptocytosis was discovered in a 6-week-old black infant. Both parents and a brother of the propositus had compensated mild Hereditary Elliptocytosis (HE). Elliptocytosis was prominent in the proband's father with the presence of numerous rod-shaped cells whereas, in the proband's mother, elliptocytosis was less marked and cells were less elongated than in the father. The proband's red cells fragmented at 45 degrees C instead of 49 degrees C for control cells. Both the parents' and brother's red cells fragmented at 47 degrees C. The deformability of the proband's red cells was markedly reduced when measured with the ektacytometer; the red cells of both the proband's parent and brother exhibited an intermediate decrease in red cell deformability. Spectrin self-association was defective in the propositus as well as in his parents and brother. Limited tryptic digestion of the proband's spectrin, followed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), revealed a complete absence of the normal 80,000 dalton alpha I domain and the presence of an abnormal 65,000 dalton peptide. Two-dimensional isoelectric focusing/SDS-PAGE of limited tryptic digests of spectrin from both the proband's parents and brother revealed a decrease in the normal 80,000 alpha I domain and the presence of the 65,000 peptide variant. On the basis of biochemic studies performed on the patients' spectrin, we concluded that the proband had homozygous HE, having inherited the structural defect of spectrin present in a heterozygous state in each of his parents. On a clinical and morphologic level, homozygous HE imitates two other forms of congenital hemolytic anemia associated with a spectrin self-association defect: HE with pycnocytosis in infancy and Hereditary Pyropoikilocytosis. This report emphasizes the importance of confronting clinical and rheological as well as biochemical investigations in studying and discussing different entities.
