IgA Nephritis and Systemic Disease

To the Editor.  —As suggested by Batlle in the editorial entitled "IgA Glomerulonephritis, Asymptomatic Hematuria, and Systemic Disease," published in the September 1981 Archives (141:1264-1265), IgA nephritis may be one manifestation of a systemic disease. In the same issue, Ramirez et al¹ describe the occurrence of IgA glomerulonephritis in two patients with mycosis fungoides.The purpose of this letter is to acknowledge our recent article about a patient with an IgA nephropathy, primary Sjögren's syndrome, and a pseudolymphoma.²Although we cannot make a clearcut statement about this association, we certainly agree with the opinion of Batlle that IgA nephropathy may be one manifestation of a systemic disease.
