Hepatitis C And Autoimmune Hepatitis - Symptoms


The typical patient with autoimmune hepatitis is female (70%). The disease may start at any age, but is most common in adolescence or early adulthood. Blood tests identify ANA or smooth muscle antibodies (SMA) in the majority of patients (60%). More than 80% of affected individuals have increased gamma globulin in the blood. Some patients have other autoimmune disorders such as thyroiditis, ulcerative colitis, diabetes mellitus, vitiligo (patchy loss of skin pigmentation), or Sjogren's syndrome (a syndrome that causes dry eyes and dry mouth).

Other liver diseases such as viral hepatitis, Wilson's disease , hemochromatosis, and alpha-1-antitrypsin deficiency should be excluded by appropriate blood tests, and the possibility of drug-induced hepatitis is ruled out by careful questioning.

The most common symptoms of autoimmune hepatitis are fatigue, abdominal discomfort, aching joints, itching, jaundice, enlarged liver, and spider angiomas (tumors) on the skin. Patients may also have complications of more advanced chronic hepatitis with cirrhosis, such as ascites (abdominal fluid) or mental confusion called encephalopathy. A liver biopsy is important to confirm the diagnosis and provide a prognosis. Liver biopsy may show mild chronic active hepatitis, more advanced chronic active hepatitis with scarring (fibrosis), or a fully developed cirrhosis.
