水肿是细胞外液体积(ECFV)的血管外成分增加。通过ECF的流体运动由流体静力学和压力控制,其受雌二醇和孕酮的影响。因此,我们假设,雌二醇减少,而雌二醇+孕酮的组合增加,蛋白质和液体运动出血管。(22 ± 2岁)。设计用促性腺激素释放激素拮抗剂抑制雌激素和孕酮16天;雌二醇(2 × 0.1 mg/天贴剂),持续第5-16天(E2),在第13-16天(E2-P4)加入(200 mg/天)。测量我们估计血管内(血浆)体积(PV),跨毛细血管白蛋白逃逸率(TERalb),结果在E2时,P[E2]由85 ± 26 pmol/ml增加到984 ± 136 pmol/ml(P<0.05),P[P4]无变化;在E2-P4中,P[E2]增加到775 ± 195 pmol/ml,P[P4]从6.4 ± 3.2增加到43.8 ± 16.2 nmol/l,P<0.05)。E2(5.1 ± 0.9)和E2-P4(5.0 ± 1.1)时的TERb低于GnRH拮抗剂(5.8 ± 0.9%/h,P<0.05)。E2未改变血浆容量,并在E2-P4期间显示出增加趋势(P= 0·07)(GnRH拮抗剂E2、E2-P4分别为48·2 ± 2·9、49·0 ± 3·0和53·9 ± 3·5 ml/kg)。椋鸟部队不受激素治疗。E2-P4期间血浆肾素活性和血清醛固酮浓度升高。结论E2或E2-P4均未改变TERa,不足以影响Starling力,表明E2或P4在这些水平的给药均不可能引起水肿。
ObjectiveOedema is an increase in the extravascular component of extracellular fluid volume (ECFV). Fluid movement across the ECF is controlled by hydrostatic and oncotic pressures, which are influenced by oestradiol and progesterone. Thus we hypothesized that oestradiol decreases, while combined oestradiol + progesterone increases, protein and fluid movement out of the vasculature.SubjectsSubjects were eight healthy women (22 ± 2 years).DesignOestrogens and progesterone were suppressed with a gonadotropin‐releasing hormone antagonist for 16 days; oestradiol (2 × 0·1 mg/day patches) was added for days 5–16 (E2) and progesterone (200 mg/day) was added for days 13–16 (E2‐P4).MeasurementsWe estimated intravascular (plasma) volume (PV), transcapillary albumin escape rate (TERalb), and Starling forces (hydrostatic pressures of plasma and interstitium, plasma colloid pressure, capillary filtration coefficient) in the forearm on days 2 (GnRH antagonist), 9 (E2) and 16 (E2‐P4).ResultsIn E2, P[E2]increased from 85 ± 26 to 984 ± 136 pmol/ml (P< 0·05), with no change in P[P4]. In E2‐P4, P[E2]increased to 775 ± 195 pmol/ml and P[P4]increased from 6·4 ± 3·2 to 43·8 ± 16·2 nmol/l,P< 0·05). TERalbwas lower during E2(5·1 ± 0·9) and E2‐P4(5·0 ± 1·1) compared to GnRH antagonist (5·8 ± 0·9%/h,P< 0·05). Plasma volume was unchanged by E2, and showed a trend (P= 0·07) for an increase during E2‐P4(48·2 ± 2·9, 49·0 ± 3·0 and 53·9 ± 3·5 ml/kg for GnRH antagonist, E2, E2‐P4, respectively). Starling forces were unaffected by hormone treatments. Plasma renin activity and serum aldosterone concentration increased during E2‐P4.ConclusionsNeither E2nor E2‐P4altered TERalbsufficiently to impact Starling forces indicating neither E2nor P4administration at these levels would likely cause oedema.
