title: Acute tubulointerstitial nephritis in a patient with Mycoplasma pneumoniae infection.
abstract: A 26-year-old man developed pneumonia, hepatitis and biopsy-verified acute tubulointerstitial nephritis coinciding with a rise and fall of complement-fixing antibodies to Mycoplasma pneumoniae. M. pneumoniae antigenic material and complement (C3) in the renal interstitium were shown by immunohistochemical techniques. A causal relationship between M. pneumoniae infection and the renal lesion is suggested.
