FRI0373 Long-term follow-up of 320 children born to mothers with systemic autoimmune diseases: a multicentre italian survey from 24 rheumatology centres

Background Rheumatic Diseases (RD) frequently affect women during reproductive age, therefore counselling on family planning is crucial for their quality of life. Children’s outcome is a major topic, but no large studies are available. Objectives To assess the long-term health conditions of children born to women with RD in a large multicentre cohort. Methods 24 Rheumatology Centres distributed the questionnaire (65 multiple-choice and 12 open-answer questions) to consecutive patients (18–55 years) in September 2015. Data were analysed dividing children upon maternal diagnosis: Chronic Arthritides (CA) and Connective Tissue Diseases (CTD). Results Data were collected for 320 children (166 males, 52%) born to 184 mothers (63 CA and 121 CTD). At the time of interview, children had a mean age of 17.1±9.6 years. Preterm delivery ( Conclusions In this long-term follow-up of children born to mothers with RD in this large, multicenter study of randomly interviewed women each AIID did not display a significantly increased frequency as compared to the literature; only coeliac showed a mild increased frequency. Children with LD had a tendency to cluster in the group of mothers with CTD, especially after maternal diagnosis (4/63, 6.3%), with a higher frequency as compared to general paediatric population. No significant relationships between ND/LD and prematurity, intrauterine drug exposure or maternal autoantibodies were identified.
