Renal Alteration | Post-preeclampsia Renal Project: Study of Nephroprotection in Women Having Suffered Preeclampsia

Renal Alteration research study

What is the primary objective of this study?

The purpose of the Post-preeclampsia Renal Project is to investigate the renal function of preeclamptic women after delivery, and to determine whether the anti-hypertensive drug named benazepril efficiently improves the dysfunctions observed.

Who is eligible to participate?

Pre-selection Criteria: - Normotensive women with no proteinuria before the 20th week of gestation AND - Women with hypertension (BP ≥140/90 mm Hg) and proteinuria (≥ 0.3 g /24h or 2++ dipstick) after the 20th week of gestation Inclusion Criteria: - Clearance of creatinine ≤ 80 ml/min (Gault et Cockcroft) - Serum creatinine ≥ 80 µmol/L - Microalbuminuria comprised between 30 and 300 mg/d and/or a urinary spot with microalbuminuria/creatinine ratio ≥ 3.5 and/or macroalbuminuria (24h urinary albumin excretion ≥ 0.500 mg) - BP ≥ 140/90 mm Hg OR ongoing antihypertensive treatment - CRP ≥ 4 mg/dL Exclusion Criteria: - Those unlikely to co-operate in the study - Those who refuse to use appropriate contraceptive measures during the treatment period (intrauterine device, oral contraceptives, condom, diaphragm) - Those with a history of pre-term delivery - Those with known history of severe allergic reaction - Those who consume drugs - Aged < 18 years old

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:PlaceboTablets; oral administration; once a day for 6 months. After this period of 6 months blinded treatment, the treatment will be stopped for 2 weeks. At the end of this washout period, a new renal evaluation is done. At that time, opened label treatment will be proposed to the women who still show renal alterations after a 2 weeks washout period

Drug:Benazepril hydrochlorideTablets (10 or 20 mg); oral administration; once a day for 6 months. After this period of 6 months blinded treatment, the treatment will be stopped for 2 weeks. At the end of this washout period, a new renal evaluation is done. At that time, opened label treatment will be proposed to the women who still show renal alterations after a 2 weeks washout period

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Control Arm
