We report six @entity1 with @entity66 in whom @entity625 was prominent at diagnosis and who improved with dietary therapy. Joint @entity158 preceded diagnosis by up to three years in five @entity1 and 15 years in one @entity1 . Joints most commonly involved were lumbar spine, hips, and knees (four cases). In three cases there were no bowel symptoms. All were seronegative. X-rays were abnormal in two cases. HLA-type A1, B8, @entity4106 was present in five and B27 in two @entity1 . Circulating immune complexes showed no consistent pattern before or after treatment. @entity66 was diagnosed in all @entity1 by jejunal biopsy, and joint symptoms in all responded to a gluten-free diet. Gluten challenge (for up to three weeks) failed to provoke @entity625 in three @entity1 tested. In a separate study of 160 treated coeliac @entity1 attending regular follow up no @entity625 attributable to @entity66 and no @entity1691 was identified, though in a control group of 100 @entity1 with @entity30 the expected incidence of seronegative @entity625 (23%) and @entity1691 (5%) was found (p less than 0.01). @entity625 appears to be a rare manifestation of @entity66 . This relationship may provide important clues to the role of gastrointestinal antigens in @entity627 .
