Pregnancies and Cystic Fibrosis
An observational study of Cystic Fibrosis, run by Hospices Civils de Lyon.
Trial summary
There have been substantial advances in care for individuals with CF, including improved nutrition and respiratory care. Women with CF are now likely to survive into adulthood with a median predicted survival of 49.7 years in 2012, which have resulted in increasingly normal lifestyles, including successful pregnancies… Read more about this study

About this study
Official title: Occurrence of Pregnancies in Women With Cystic Fibrosis
There have been substantial advances in care for individuals with CF, including improved nutrition and respiratory care. Women with CF are now likely to survive into adulthood with a median predicted survival of 49.7 years in 2012, which have resulted in increasingly normal lifestyles, including successful pregnancies in women with CF. The number of pregnancies in CF women has increased as reported by the 2013 Annual Data Report from the French CF Registry (6 pregnancies in 1992 to 53 in 2012). Pregnancy adds many physiological stresses to the body, particularly on pulmonary function (decrease in residual volume, expiratory reserve capacity) and nutritional status (increase in nutritional needs). In women with CF, these added stresses could theoretically affect survival, with difficulties to maintain adequate nutrition and an unpredictable effect on lung function. A number of studies published over the past 15 years have attempted to clarify the risk of pregnancy in women with CF to guide clinicians and women. Many authors compared the outcomes of pregnant CF women to non-pregnant CF women regardless of nutritional status, lung function, diabetes mellitus, bacteriological colonization. In literature, pregnancy was possible and well tolerated in CF women with mild disease if associated with more intensive monitoring and aggressive treatment during pregnancy, with particular emphasis on nutrition and weight gain. CF women have an increased likelihood of receiving treatment for diabetes both during and after pregnancy. Furthermore diabetes mellitus has been associated with more severe pulmonary disease, more frequent pulmonary exacerbations, poorer nutritional status and a reduced life expectancy. Pre-pregnancy diabetes mellitus is associated with a poorer prognosis for pregnancy in general population. Severe forms of CF, including pre-pregnancy diabetes mellitus might as well do badly with accelerated decline after pregnancy. To determine the effect of pre-pregnancy diabetes on maternal decline after pregnancy, we will compare FEV1 and BMI rates of decline, during a two-years follow-up period after pregnancies, reported in the French CF Registry, according to their diabetic status.

Questions about this trial
What is this clinical trial studying?
An observational study of Cystic Fibrosis, run by Hospices Civils de Lyon.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 25 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in FEV1 (time frame: 12 months following the pregnancy). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2017.
