An Immunofluorescence Study of the Skin in Diabetes Mellitus

Abstract

ABSTRACT. The clinically normal skin of the lower back of 30 patients with diabetes mellitus was examined, using the direct immunofluorescence technique. No deposit of immunoglobulins or complement (C3) could be demonstrated, while other authors have previously reported lupus‐like deposits in diabetes mellitus. As other discrepant studies of skin immunofluorescence have been published, it is suggested that the standards of the various immunopathology laboratories are different. This may explain why the actual value of the lupus band test remains controversial.
