[Mucoviscidosis and pregnancy].

We have seen a patient who became pregnant. She was suffering from cystic fibrosis diagnosed late in life at the age of 26 years. Her case has allowed the authors to make some observations on this association of pregnancy with cystic fibrosis which will become increasingly common. 5% of individuals are heterozygous for this condition. The prospect for these patients surviving gets better and better. Although their fertility seems to be lowered it is possible for them to become pregnant. They are caught in the web of almost constant episodes of broncho-pulmonary infection with lasting effects on their respiratory capacities in 50% of cases. About 83% of these patients will deliver prematurely because of the respiratory distress they suffer. It is difficult to predict the long-term effects of pregnancy on the survival of these patients since the mortality rate anyhow is about 10% per year. According to the literature pregnancy will cause a permanent deterioration in respiratory function in about 37% of cases. The history of this particular case should be able to give new hope to some women suffering from this condition. All the same, there are a large number of problems that still have to be dealt with.
