title: Immune deficiency in familial duodenal atresia.
abstract: The familial occurrence of duodenal atresia is uncommon. This study evaluated the inheritance patterns, the nature and associations, and the presence of immunologic deficits in duodenal atresia recurring in at least three siblings each in two nonrelated families. In the first family, an association with Fanconi's anemia was observed in three of seven pregnancies (2 boys, 1 girl) suggesting an autosomal recessive mode of transmission. Patients died as a result of overwhelming (fungal) septicemia in association with pancytopenia. In a second family, identical multiple atresias occurred in two female siblings born 18 months apart and a third child with a duodenal stenosis. Overwhelming sepsis and a T-cell dysfunction was seen in the postoperative period, which had partially corrected by follow-up at 5 months. A history of family occurrence of duodenal atresia should alert the physician to the possibility of associated pathology including immune deficiency states.
