This is a retrospective study concerning patients presenting overlap syndrome diagnosed between january 1998 and December 2001. Five patients fulfilled the diagnosis criteria of overlap syndrome. The optimal type of treatment of the overlap syndrome was not known. Treatment with UDCA or immunosuppressor alone are not efficient. Combination of these drugs should be evaluated in further studies.
