BACKGROUND: The evolution of @entity31 in pregnancy is far from clear. While some authors state that the disease aggravates during this period, others do not share this opinion. AIM: To assess the evolution of @entity31 in pregnancy. @entity1 AND METHODS: A paired case-control design was used in which 15 @entity1 , with diagnosed @entity31 at the moment of becoming pregnant, were followed for 12 months and the activity of the disease was compared with that of the 12 months preceding the pregnancy. The activity of the disease in the period preceding the pregnancy was gathered retrospectively from the @entity1 's charts. RESULTS: The mean age of the first @entity31 crisis was 24 years. It was moderate in 49% and severe in 35% of @entity1 . During pregnancy 55% of @entity1 did not have a crisis, compared with 26.7% during the period preceding pregnancy (relative risk of not having a crisis during pregnancy of 1.7). During both periods, seven @entity1 had digestive complications, whereas extra digestive complications were not observed in 60% of @entity1 during pregnancy and 11.8% of @entity1 during the preceding period. Perinatal results were similar to those of the general population. CONCLUSIONS: In our group of @entity1 the evolution of @entity31 was better during pregnancy, reflected by a lower number of crisis.
