[Chronic diarrhea with selective IgA deficit associated with Turner's syndrome].
Three cases of selective IgA deficit with chronic diarrhea associated to Turner's syndrome are reported. The first patient presented gluten intolerance (celiac disease), confirmed by intestinal biopsy. The second patient turned out to suffer from cow's milk and gluten intolerance, and in the third an intestinal lambliasis was detected as well as gluten intolerance. Cytogenetic studies revealed in two patients a Turner's syndrome variant with isochromosome X, and the third presented Turner's syndrome associated with chromosome breakage. In all of the patients a history of repetitive upper respiratory infections and otitis was reported. The low incidence found in the literature of this rare association is also remarked, speculating about the role played by chromosome X in IgA synthesis.
