Randomized Controlled Trial Multicenter Study
The Control of Hypertension In Pregnancy Study pilot trial.
To determine whether 'less tight' (versus 'tight') control of nonsevere hypertension results in a difference in diastolic blood pressure (dBP) between groups. ⋯ The CHIPS pilot trial confirms the feasibility and importance of a large definitive trial to determine the effects of less tight control on serious perinatal and maternal complications.

Pregnancy complications in women with Factor XI deficiency were assessed in this retrospective analysis. All nonnulliparous women registered with Factor XI deficiency in the East Midlands region were included. Each woman was classified into 'bleeder' or 'nonbleeder'. ⋯ Miscarriage rate appeared unchanged. We conclude that PPH is increased in a subgroup with a bleeding phenotype. Larger studies are needed to define the underlying factors.
