title: An immunofluorescent study of the ampicillin rash.
abstract: The aetiology of the ampicillin rash is uncertain although numerous theories have been proposed--mainly immunological. One such concerns the presence of anti-epithelial antibodies which have received conflicting reports in the literature. In this study, skin biopsies from three patients with a maculopapular ampicillin-rash were studied by immunofluorescence to investigate the presence of anti-epithelial antibodies. However immunofluorescence for IgG, IgM, IgA and C3 was completely negative so that we were unable to provide any support for this particular hypothesis.
