Liver/kidney microsome autoantibodies are detectable in different forms of chronic hepatitis, namely autoimmune, viral, and drug-induced hepatitis and in hepatitis associated with Type 1 autoimmune polyglandular syndrome. Based on the aetiology of chronic hepatitis, liver/kidney microsome autoantibodies are directed against different enzymes with very little overlap. Thus, the simple Indirect Immunofluorescence test, which is universally used as a screening test to detect autoantibodies, does not allow subtyping of liver/kidney microsome autoantibodies. This brief review stresses the need to use methods such as Western-Blotting and enzyme-linked immunosorbent assay together with Indirect Immunofluorescence to characterize the liver/kidney microsome autoantibodies. Identification of the liver/kidney microsome target antigens, when possible, makes differential diagnosis easier and, at times, may help the clinician to choose the best approach to treatment.

Abstract
Liver/kidney microsome autoantibodies are detectable in different forms of chronic hepatitis, namely autoimmune, viral, and drug-induced hepatitis and in hepatitis associated with Type 1 autoimmune polyglandular syndrome. Based on the aetiology of chronic hepatitis, liver/kidney microsome autoantibodies are directed against different enzymes with very little overlap. Thus, the simple Indirect Immunofluorescence test, which is universally used as a screening test to detect autoantibodies, does not allow subtyping of liver/kidney microsome autoantibodies. This brief review stresses the need to use methods such as Western-Blotting and enzyme-linked immunosorbent assay together with Indirect Immunofluorescence to characterize the liver/kidney microsome autoantibodies. Identification of the liver/kidney microsome target antigens, when possible, makes differential diagnosis easier and, at times, may help the clinician to choose the best approach to treatment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
