[Effects of micronized natural progesterone on the liver during the third trimester of pregnancy].

In France, prescription of micronized progesterone at high doses of 900 to 1200 mg/day is common practice in the case of preterm delivery, even though this is neither an indication nor a posology given for marketing authorisation. A few cases of gestational pruritus have been reported during such use, associated with cholestasic and/or cytolytic hepatic disorders. We report here the results of a controlled, double-blind study versus a placebo, aimed at assessing the effects on the liver of micronized progesterone administered orally at high doses (900-1200 mg/day), conducted in a population of 201 women presenting moderate menace of preterm delivery during the third trimester of pregnancy. 85 patients received micronized progesterone and 116 the placebo. The increase above normal levels of total biliary acids (TBA) and aminotransferases (ASAT, ALAT), was significantly more frequent in the micronized progesterone than in the placebo group. Among the 26 patients (14%) with a level of TBA superior to 10 mumoles/l during treatment, 18 belonged to the progesterone and 8 to the placebo group (p = 0.004); the 6 patients (3.4%) with increased ASAT were all under micronized progesterone (p < 0.001), as were the 10 patients (5.6%) with increased ALAT (p < 0.001). However, there is no statistically significant difference between the two groups regarding the occurrence of clinical manifestations (icterus, pruritus) which could be attributed to gravid cholestasis. We may conclude from this prospective study that, during the third trimester of pregnancy, micronized progesterone is associated with a significant risk of biological cholestasis. This would suggest that in patients genetically predisposed towards gravid cholestasis, micronized progesterone could be a factor favoursing this disease.

[Programmed autologous transfusion in obstetrics. Blood samples in 100 patients in the last month of pregnancy].

OBJECTIVES: Evaluation (usefulness and safety) of programmed autologous transfusion in obstetrics. SITE. Blood Transfusion Centre, Hôpital Louis-Mourier, F 92700 Colombes. PATIENTS: Prospective study of 150 patients for whom blood withdrawal was planned during the last month of pregnancy. Entry criteria were either a risk of haemorrhage or persistent patient request. PROTOCOL: Two withdrawals were planned during the last month of pregnancy at the out-patient clinic at a one-week interval. The autologous units were transfused per-partum in case of haemorrhage and/or post-partum in case of anaemia. RESULTS: One hundred pregnant women entered the protocol (43 had a risk of haemorrhage). Both preplanned withdrawals were made in 60 of these patients. Per-partum transfusions were necessary in only 7 patients including 4/43 with a risk factor (9%) and 3/57 with no risk factor (5%). Post-partum transfusions were made in 22 other patients. Consequently, 117 of the 160 units collected were not used (73%). CONCLUSION: Despite good tolerance (5% incidence) due to the known problems in evaluating the risk of haemorrhage and the small percentage of patients without risk factors who were transfused per-partum, we have decided to reserve this protocol for patients with an authentically identified risk of haemorrhage (placenta praevia, cesarean section, uterine scar tissue).

[Neonatal digestive implantation of streptococcus group B. Influence of antibiotic therapy].

Group B streptococcus (GBS) is an important cause of neonatal infection. Early-onset diseases are due to perinatal contamination. The epidemiology of late-onset infections is poorly known. Maternal colonization may be responsible for some of them. The relationships between neonatal colonization and late disease could be a colonization of the gut. The purpose of this 3 year-prospective study was to analyse the kinetics of gut colonization in neonates and the influence of antibiotherapy. One hundred and nineteen infants less than one month of age were included because of the presence of GBS in their gastric aspirates or GBS infection. Depending on the therapeutic strategy, the infants were separated into 3 groups: 1) amoxicillin plus aminoside greater than or equal to 10 days because of neonatal infection (28 infants), 2) same combination less than or equal to 5 days because a GBS infection was suspected but not confirmed (17 infants), 3) no antibiotics (77 infants). Fecal flora was regularly analysed by differential count. Antibiotics caused rapid disappearance of GBS from the gut. However, the same strain reappeared after stopping the antibiotics at a rate of 13.5%. Without antibiotics, GBS was implanted in 33% of cases. This difference of implantation rate is statistically significant (p less than 0.05). No GBS infection was observed in any infant after a follow-up examination of 6 months to 2 years. Among the clinical and bacteriological factors studied, adhesion only was correlated with the GBS implantation. These results allow to discuss therapeutic abstention in colonized infants without any signs of infection.

[Epidemiology and prevention of perinatal group B streptococcal infections].

Neonatal group B streptococcal infection is frequent and may be responsible for lethal neonatal septicaemia. Its preventive treatment is still hotly debated. Digestive and genital tracts colonization is frequent in mother (15-20% of the cases) but it is unstable. About one out of two infants born of a colonized woman becomes colonized or infected. Neonates can also be colonized during their stay in maternity hospitals. Colonization is much more frequent than infection which strikes 0.2 to 0.6 per cent of neonates (at a very early period in two-thirds of the cases), but it jeopardizes their prognosis for life and later their functional prognosis. Prematurity and chorioamnionitis are the two main infection facilitating factors. Some of the various measures proposed to prevent infection in neonates, such as antibiotic therapy of colonized mothers during pregnancy and of symptomatic colonized neonates, do not seem to be effective, but others are interesting, including administration of antibiotics to mothers during delivery in high-risk situations, combined with early detection and immediate bactericidal treatment of neonatal infections.

[Value of a percutaneous estrogen solution in stopping lactation].

An open trial involving 121 women was carried out to compare the efficacy and safety of a percutaneous estrogen solution and of an anti-prolactin solution. The complete inhibition of the let-down of milk was slightly less frequently obtained with the Percutacrine Oestrogénique that with Parlodel. The efficacy of Percutacrine Oestrogénique was linked to two conditions of administration: administration soon after delivery and compliance with the dosage, which was less frequently achieved than with Parlodel. In contrast, the clinical safety of Percutacrine Oestrogénique was excellent, and significantly better than that of Parlodel, notably with regard to dizziness (p less than 0.001 for the first 5 days of treatment). The incidence of the depressive tendency commonly observed post-partum was lower in the group of women receiving Percutacrine Oestrogénique, and reached the level of significance after 10 days of treatment.
