PREVASCLERO: Is a History of Pre-eclampsia a Risk Factor for Vascular Phenotype in Women With Systemic Sclerosis?
Study Details
Study Description
Brief Summary
Background:
Pre-eclampsia, defined by the association of an arterial hypertension and significant proteinuria after 20 weeks of gestation, complicates 1 to 2% of pregnancies in France. Its pathophysiology involves angiogenesis impairment, upregulated maternal systemic inflammatory response, activation of oxidative stress and endothelial dysfunction.
In a recent Danish nation-wide cohort study, pre-eclampsia was associated with a 69% increased risk of later developing scleroderma.
Type of study: prospective observational case-control study. Primary objective of the study:
to determine if a history of pre-eclampsia before systemic sclerosis diagnosis is an independent risk factor for vascular phenotype in sclerodermic women.
Secondary objective: to describe all risk factors for vascular phenotype in sclerodermic women with a previous pregnancy longer than 6 months before scleroderma diagnosis.

Detailed Description
Background :
Pre-eclampsia is defined by the association of an arterial hypertension and significant proteinuria after 20 weeks of gestation. It complicates 1 to 2% of pregnancies in France. Its pathophysiology involves angiogenesis impairment, upregulated maternal systemic inflammatory response, activation of oxidative stress and endothelial dysfunction.
In a recent Danish nation-wide cohort study, pre-eclampsia was associated with a 69% increased risk of later developing scleroderma. A case-control study on 103 women with systemic sclerosis compared to 103 control women had already found an increased incidence of previous vasculoplacental disorders in women with systemic sclerosis. Women developed systemic sclerosis on average 27 years after their first pregnancy.
Primary objective of the study : to determine if a history of pre-eclampsia before systemic sclerosis diagnosis is an independent risk factor for vascular phenotype in sclerodermic women.
Secondary objective: to describe all risk factors for vascular phenotype in sclerodermic women with a previous pregnancy longer than 6 months before scleroderma diagnosis.
Conduct of the study:
It is a prospective observational case-control study. Cases will be defined as women with systemic sclerosis, specific vascular complications (digital ulcers, specific cardiac involvement of systemic sclerosis including pulmonary arterial hypertension, renal crisis) and with a previous pregnancy longer than 6 months before systemic sclerosis diagnosis.
Controls will be defined as women with systemic sclerosis, no specific vascular complication and with a previous pregnancy longer than 6 months before systemic sclerosis diagnosis.
Conduct of the study:
A self-administered " pregnancy " questionnaire will be given to each women with systemic sclerosis of the cohort group during the annual follow-up consultation. A case report form will be completed at the same time by the physician in charge of the patient.
The " pregnancy " questionnaire will consist of two parts :
-
A part " pre-eclampsia questionnaire ", derived from the translation in French of a questionnaire validated in English.
-
A second part with additional questions on pregnancies. The duration of participation to the study will be of one day. The duration of the inclusion period will be of 24 months. Needed number of patients : 378 women, 126 "cases" and 252 "control" .
Perspectives of the study :
If this study demonstrates that a previous pre-eclampsia is an independent risk factor for vascular phenotype in women with systemic sclerosis, it will be mandatory to look for a history of pre-eclampsia in women at the time of systemic sclerosis diagnosis. Besides, the women with a history of pre-eclampsia should be monitored more frequently for vascular complications related to systemic sclerosis.

Outcome Measures
Primary Outcome Measures
- History of pre-eclampsia before systemic sclerosis diagnosis [Inclusion (Day 0)]
Primary outcome will be evaluated by the proportion of women with a history of pre-eclampsia before systemic sclerosis diagnosis in each group. Primary judgement criterion will be the response of a woman to the " pre-eclampsia questionnaire ". The aim is to determine if a history of pre-eclampsia before systemic sclerosis diagnosis is an independent prognostic factor for vascular phenotype in sclerodermic women. Primary judgement criterion: Responses of the women to the " pre-eclampsia questionnaire ".
Secondary Outcome Measures
- Risk factors for vascular phenotype in sclerodermic women with a previous pregnancy longer than 6 months [Inclusion (Day 0)]
Secondary outcomes will be evaluated by the proportion of women with chronic hypertension, diffuse systemic sclerosis, disease duration > 5 years, anti-centromere antibodies, anti-Scl70 antibodies, antiphospholipid antibodies, antiphospholipid syndrome, interstitial lung disease, and tobacco use, in each group, mean age at systemic sclerosis diagnosis in each group. Secondary judgement criteria will be patients' clinical, biological and radiological medical data. The aim is to describe all risk factors for vascular phenotype in sclerodermic women with a previous pregnancy longer than 6 months.
