An endogenous sodium pump inhibitor, or digitalis-like factor (DLF), has been postulated to mediate essential hypertension. It may also play a role in preeclampsia. However, studies of this factor in hypertensive pregnancy have not provided consistent findings. Part of this may be due to the absence of subclassification of pregnant women with pregnancy-induced hypertension (PIH) when assessing these parameters. In this study we explored serum DLF and digoxin-like immunoreactive factor (DLIF) in insulin-dependent diabetic (IDDM) women with normotensive pregnancies or PIH, comparing them to each other and to nondiabetic pregnant women. Our results demonstrated that nondiabetic women with preeclampsia (PE, PIH with proteinuria) had significantly increased serum DLF and DLIF compared to normotensive pregnant women (NL BP). Women with transient hypertension of pregnancy (THP, PIH without proteinuria) had intermediate values (DLF. NL BP: 3.3 +/- 0.6, THP: 4.8 +/- 1.1, PE: 7.6 +/- 1.3% inhibition [Na,K]-ATPase, P < .05 ANOVA; DLIF. NL BP: 0.22 +/- 0.02, THP: 0.28 +/- 0.03, PE: 0.35 +/- 0.02 ng digoxin equivalents/mL, P < .05 ANOVA). Pregnant normotensive IDDM women had significantly higher serum DLF and DLIF activity than their nondiabetic counterparts (DLF. non-IDDM NL BP: 3.3 +/- 0.6 v IDDM NL BP: 8.8 +/- 1.2% inhibition [Na,K]-ATPase, P = .0008; DLIF. non-IDDM NL BP: 0.22 +/- 0.02 v IDDM NL BP: 0.31 +/- 0.02 ng digoxin equivalents/mL, P = .005).(ABSTRACT TRUNCATED AT 250 WORDS)

UI MeSH Term Description Entries
D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more. Blood Pressure, High,Blood Pressures, High,High Blood Pressure,High Blood Pressures
D011225 Pre-Eclampsia A complication of PREGNANCY, characterized by a complex of symptoms including maternal HYPERTENSION and PROTEINURIA with or without pathological EDEMA. Symptoms may range between mild and severe. Pre-eclampsia usually occurs after the 20th week of gestation, but may develop before this time in the presence of trophoblastic disease.
