[Three patients with autoimmune hepatitis: the importance of early diagnosis and remission].

A 70-year-old woman presented with impaired memory and depressive symptoms and two women aged 53 and 30 years, respectively, presented with general malaise and fatigue. All were diagnosed with and treated for autoimmune hepatitis (AIH). The first patient developed a relapse during treatment withdrawal; she recovered and maintained remission after the initial dose of medication had been restarted and the medication was tapered more gradually. The second patient had an incomplete remission and later developed liver failure; she was eligible for a liver transplant. The third woman became pregnant during treatment and developed a relapse after delivery; remission was induced and maintained after the immunosuppression was temporally increased. AIH is a chronic progressive liver disease characterised by abnormal serum levels of liver enzymes, hypergammaglobulinaemia, auto-antibodies against cell nuclei (ANA), smooth muscle (SMA), or liver and kidney microsomes (LKM), interface hepatitis and the absence of other chronic liver disease. Early diagnosis is essential because therapy can markedly improve prognosis. However, there is no specific diagnostic test for AIH. It is important to induce and maintain remission with immunosuppressive therapy.
