Hypertension develops in 10% of pregnancies. Snoring, a marker of obstructive sleep apnoea, is a newly identified risk factor for gestational hypertension. Moreover, obstructive sleep apnoea is an independent risk factor for incident hypertension in the non-pregnant population. The aim of the present study was to test the hypothesis that obstructive sleep apnoea is associated with new onset of hypertension among pregnant females.A case-control study was performed involving 17 pregnant females with gestational hypertension and 33 pregnant females without hypertension. Subjects were frequency-matched for gestational age and recruited in a tertiary obstetrical centre. Obstructive sleep apnoea was ascertained by polysomnography and defined by an apnoea/hypopnoea index (AHI) of o15 events?h -1 , without requirement for desaturation. The mean¡SD AHI for normotensive pregnant females was 18.2¡12.2 events?h -1 compared with 38.6¡36.7 events?h -1 for females with hypertensive pregnancies. The crude odds ratio for the presence of obstructive sleep apnoea given the presence of gestational hypertension was 5.6. The odds ratio was 7.5 (95% confidence interval 3.5-16.2), based on a logistic regression model with adjustment for maternal age, gestational age, pre-pregnancy body mass index, prior pregnancies, and previous live births.In conclusion, gestational hypertension appears to be strongly associated with the presence of obstructive sleep apnoea.

We report the successful management of a case of hemolytic disease and hydrops fetalis secondary to anti Rh 17 antibodies in a woman with the rare D-- phenotype. We discuss the efficacy of intravenous immunoglobulins in treating hemolytic disease of the newborn infant.

the higher rate of pregnancy complications for women ≥ 40 years is not further increased after 45 years of age.
