Management of Nephrotic Syndrome in the Pregnant Patient.

Objective: To present a case series of pregnant women with nephrotic syndrome, describe maternal and fetal outcomes, and propose treatment strategies. Study Design: A retrospective cohort case review of 11 pregnant women with nephrotic syndrome was performed over 2 years. Treatment regimens and trends were recorded. Linear regression was used for continuous outcomes, and logistic regression for categorical outcomes (p<0.05). Results: On first admission, 3 of 11 patients had a serum creatinine >1.4 mg/dL; all 11 exhibited an antepartum increase in creatinine. Two required antepartum dialysis, and 3 were dialyzed postpartum. Initial mean 24-hour urine protein was 10,522 mg (2,160-36,603) and increased to 26,220 mg (4,650-49,980). Pregravid weight increased from a mean 95 kg (BMI 33.8) to 112 kg (BMI 39.9) at time of delivery. Mean antepartum and postpartum diuresis was 33.2 L (±25.8) and 5.2 L (±8.2), respectively. Mean serum albumin levels were 2 g/dL. Ten patients received intravenous diuretics and 9 received intravenous albumin. Mean gestational age at delivery was 34w 3d (30.4-38.4). Conclusion: Pregnant women with nephrotic syndrome can be managed successfully by a collaborative team of obstetricians and nephrologists with careful diuresis, repletion of albumin, and administration of anticoagulants, when necessary, to deliver a healthy, probably preterm, neonate.

A true cornual (interstitial) pregnancy resulting in a viable fetus.

BACKGROUND: Interstitial ectopic pregnancies are known for their dangerous implantation location and high risk of rupture. CASE: We report an interstitial pregnancy that was not ruptured at the time of cesarean delivery. Hysterectomy was not necessary and a viable fetus was delivered with a neonatal intensive care unit stay compatible to any neonate of his gestational age. CONCLUSION: In very rare circumstances, interstitial pregnancies can result in a viable fetus, and careful inspection of second-trimester ultrasonogram can lead to proper management of complicated ectopic pregnancies.

Hyperemesis gravidarum and fetal outcome.

BACKGROUND: Hyperemesis gravidarum (HG) is reported in 0.5-2% of all pregnancies. The purpose of this research was to evaluate the relationship of maternal HG, neonatal birth weight, and birth outcomes. METHODS: This is a prospective cohort study of 45 patients diagnosed, by Fairweather's criteria, with HG compared with 306 non-HG control pregnant patients with singleton pregnancies. Sociodemographic and clinical data were obtained from the pregnant patients. Neonatal data were also collected, including indicators of neonatal wellness. RESULTS: Significantly higher incidences of being nonwhite (33% vs 16%; p < .05) and of attaining post-high school education (60% vs 38%) were noted in the HG group, relative to controls. Mothers in the control group experienced greater gestational weight gain, 14.9 +/- 0.3 kg (mean +/- SEM) relative to mothers in the HG group (10.6 +/- 1.3 kg). Infants from HG pregnancies manifested significantly lower birth weight (3.23 +/- 0.09 kg vs 3.52 +/- 0.03 kg), younger gestational age (38.4 +/- 0.3 weeks vs 39.7 +/- 0.1 weeks), and a greater length of hospital stay (2.9 +/- 0.5 days vs 1.8 +/- 0.1 day), relative to infants from the control group. After undergoing multivariate analysis, HG was a significant predictor of decreased gestational age and increased hospital length of stay. CONCLUSIONS: Infants born of women who had HG are more likely to experience decreased gestational age and increased length of hospital stay. Efficacy of early and aggressive treatment of HG, including nutrition support, in minimizing these outcomes needs to be studied.

The pattern of change in the lecithin/sphingomyelin ratio in patients with preterm premature rupture of membranes between 24 and 34 weeks' gestation.

OBJECTIVE: To report the pattern of change in the lecithin/sphingomyelin (L/S) ratio in patients with preterm premature rupture of membranes (PPROM) between 24 and 34 weeks' gestation. STUDY DESIGN: L/S was determined prospectively using transvaginally and transabdominally collected amniotic fluid from patients with PPROM between 24 and 34 weeks' gestation. Samples were collected prospectively on admission and every 48 to 96 hours until L/S was > or =2.0. All patients received intramuscular betamethasone weekly. RESULTS: Fifty-five patients were included in the study. One hundred twenty-seven samples were collected transvaginally and nine were collected transabdominally. Cox regression analysis showed that a higher initial L/S value and more advanced gestational age were associated with accelerated lung maturation. Among patients at > or =29 weeks' gestation with an initial L/S of > or =1.5 and <2.0 (n=17), 15 of 17 (88%) reached L/S > or = 2 at a mean of 3.1 +/- 1.7 days (range 1.0 to 7.0 days). With an initial L/S of > or =1.0 and <1.5 (n=16), 14 of 16 (88%) patients reached L/S > or =2 at a mean of 4.1 +/- 1.9 days (range 1.7 to 7.0 days). With an initial L/S of <1.0 (n=11), 6 of 11 (54%) patients reached L/S > or =2 at a mean of 5.0 +/- 1.6 days (range 4.7 to 6.8 days). CONCLUSION: Our data document a dramatic acceleration of fetal lung maturation among patients with PPROM at > or = 29 weeks.
