In the present study we report on four cases of acute interstitial
nephritis (AIN) and two cases of hepatitis induced by quinolone. We show by
immunoblotting analysis that all sera from these patients contained
autoantibodies that recognize a 65-kDa protein expressed in normal human
kidney and liver microsomes. Only 6% of sera from healthy individuals who
did not ingest quinolone recognized the same protein. These findings
suggest that the presence of autoantibodies could be used as a sensitive
marker and that a modification of microsomal proteins by quinolone itself
or by a metabolite could generate an autoimmune response.
