Sjögren-type syndrome after allogeneic bone-marrow transplantation.
Four patients, treated for hematologic disorders with bone-marrow transplants from HLA-identical siblings, spontaneously complained of dry eyes 8 to 12 months after transplantation. Four allograft recipients and two recipients of autologous bone-marrow transplants were evaluated for xerophthalmia and xerostomia. Three allogeneic marrow recipients had evidence of keratoconjunctivitis sicca, and two had decreased parotid gland function. All four allograft recipients had minor salivary gland histopathology identical to that of Sjögren's syndrome. The severity of symptoms and histologic lesions corresponded with the severity of chronic graft-versus-host disease. In addition, one patient developed sclerodermatous skin changes, another had discoid lupus erythematosus, and two patients had laboratory evidence of cholestasis. None of the patients had autoantibodies but all had hypergammaglobulinemia. In contrast, none of the recipients of autologous bone marrow had clinical, laboratory, or histologic findings resembling Sjögren's syndrome.
