[Primary biliary cirrhosis and autoimmune hepatitis overlap syndrome: therapeutic features in 5 patients].
Autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC) are two different liver diseases, however diagnosis criteria of these two affections can be found in a same patient. The aim of this study is to relate the clinical, serologic and histologic features of patients presenting the overlap syndrome, AIH-PBC, defined by the presence of at least of two main criteria of each disease and to evaluate their response to therapy.


METHODS
This was a retrospective study concerning patients presenting overlap syndrome diagnosed between January 1998 and December 2001. These patients had been treated with ursodesoxycholic acid (AUDC) or prednisone and azathioprine or a combination of these three products. Clinical and biological criteria were used to assess response to therapy.


RESULTS
Five patients fulfilled the diagnostic criteria of overlap syndrome. All patients were females, the median age was 38 years (range: 19-65 years). Three patients were treated by UDCA, a clinical and biological response was noted in only one patient. Two patients were treated by prednisone and azathioprine without any remission. Three patients were treated by a combination of these three products with a good response in two cases.


CONCLUSIONS
Optimal treatment for overlap AIH-PBC syndrome remains to be determined. Treatment with UDCA or immunosuppressor alone is not efficient. A combination of these drugs should be evaluated in further studies.
