A patient who developed generalized autoimmune myasthenia gravis six years after the spontaneous remission of a stiff-man syndrome is described. He also suffered from chronic active hepatitis and had radiological evidence of a thymoma. He did not have diabetes mellitus. Besides anti-nicotinic acetylcholine receptor antibodies, anti-nuclear, anti-DNA, anti-mitochondrial and anti-skeletal muscle antibodies were found in his serum, while islet-cell antibodies were absent. Immunocytochemistry studies failed to demonstrate autoantibodies to GABA-ergic nerve terminals, although an aspecific neuronal immunostaining was observed. The clinical and immunological features of this case support the hypothesis of a dysimmune pathogenesis of SMS, also in cases not associated with autoimmunity to GABA-ergic nerve terminals. Furthermore, a relationship between thymoma and the neurological syndromes discussed could be considered.

Altogether 155 patients with different clinical types of liver lesions were examined: 73 with chronic persistent hepatitis (CPH), 39 with chronic active hepatitis (CAH), and 43 with liver cirrhosis (LC). The patients with chronic liver diseases demonstrated hyperinsulinemia and a decrease in glucose tolerance, a frequency and degree of this decrease growing with the severity of a pathological process. It is postulated taking experiments with partial hepatectomy of rats by way of example that intolerance to glucose and hyperinsulinemia is caused by partial loss of glycogen synthetic function by the liver resulting from a decrease in the number of functionally active cell elements. Experience with 8 LC patients with secondary diabetes mellitus has shown that the addition of the latter is connected with the reduction of secretory capacity of pancreatic beta-cells and with the development of relative insulin insufficiency.

IgA deposition in hepatic sinusoids was demonstrated in liver biopsies from 26 patients with alcohol- or diabetes-related fatty liver and fatty liver hepatitis, and from 13 patients with normal liver or chronic active hepatitis. The pattern and extent of IgA deposition were similar in alcoholic and diabetic patients, a linear, continuous pattern being the most common. Staining for IgA cannot therefore be used to evaluate aetiology of fatty liver hepatitis in these two groups of patients.

In patients with chronic liver disease, the reliability of various criteria generally used to diagnose impaired glucose tolerance and diabetes was evaluated. Twenty-one patients with chronic persistent hepatitis, 68 patients with chronic active hepatitis and 57 patients with liver cirrhosis were studied. All subjects underwent an oral glucose tolerance test (75 g). Impaired glucose tolerance and diabetes were diagnosed according to the criteria established by: the National Diabetes Study Group; Fajans and Conn; the European Diabetes Study Group; Deutsche Diabetes Gesellschaft; Kobberling & Creutzfeld criteria 1 and 2; Wilkerson; and the University Group Diabetes Program. The results obtained are in partial agreement with other reported data, showing a high prevalence of both impaired glucose tolerance and diabetes in chronic liver disease, with a positive correlation to the severity of hepatic involvement. However, our results show that the agreement among the criteria most frequently used for diagnosing impaired glucose tolerance and diabetes is still far from satisfactory.

We studied 29 patients with thalassaemia major who had received intensive chelation for between 6.2 and 8.8 years. All patients had normal oral glucose tolerance tests before subcutaneous chelation therapy was introduced and 22 of 29 patients had normal liver function tests. At the end of the period of study 12 patients still had normal oral glucose tolerance (7 with normal liver function tests and 5 with chronic active hepatitis). On the other hand, 11 patients had developed impaired glucose tolerance tests (3 patients had normal liver function tests, 5 with chronic active hepatitis and 3 with cirrhosis), and 6 patients had developed frank diabetes mellitus (one with chronic active hepatitis and 5 with cirrhosis). Patients with chronic active hepatitis showed 91% positivity for one or more hepatitis B markers whilst all patients with cirrhosis were positive. Ferritin levels before subcutaneous chelation in patients with normal oral glucose tolerance tests were lower than in those patients with abnormal oral glucose tolerance or diabetes (P less than 0.05) but none had normal serum ferritin levels. In addition, a positive correlation was found between glucose area under the curve after chelation therapy and serum ferritin levels (r = 0.47, P less than 0.01). It is apparent that long term chelation therapy does not prevent the development of abnormal oral glucose tolerance in chronically transfused patients. More intensive chelation therapy is needed to prevent tissue damage. Chronic liver disease may have an important role to play in the deterioration of glucose tolerance.

Sixty-five patients with histologically proven chronic active hepatitis of unknown cause but associated with the antiliver/kidney microsome antibody type 1, confirmed by immunofluorescence and immunoprecipitation, were selected as forming a special entity. This disease was found to be rare with a prevalence of 5/1,000,000. The female to male ratio was 8:1. The condition occurred at all ages but was most common between the ages of 2 and 14 years. In 22 of the 65 cases, the hepatitis was associated with an autoimmune disease, most commonly insulin-dependent diabetes, autoimmune thyroid disease and vitiligo. The same autoimmune diseases were present in first-degree relatives from seven families. In 36 cases, the onset of disease resembled acute viral hepatitis. Serum biochemical tests showed marked elevation in aminotransaminases and hypergammaglobulinemia. Paradoxically, serum and salivary IgA levels were often normal or low. Histologic findings were multifocal hepatic necrosis with bridging in the acute stage, and aggressive hepatitis with mononuclear cell infiltration or macronodular cirrhosis in the late stages. Serologically, apart from the presence of antiliver/kidney microsome antibody type 1, the disease was characterized by the absence of antiactin, antimitochondria and antinucleus antibodies; however, organ-specific autoantibodies were often present. The clinical course was usually severe: six patients in the acute stage presented with fulminant hepatitis, and all, except two, other patients progressed to cirrhosis. Prolonged treatment with corticosteroids and immunosuppressants was usually effective in rendering the cirrhosis inactive. The cumulative survival rate was 51% at 14 years. We propose to call this entity "anti-LKM1 chronic active hepatitis" or "autoimmune hepatitis type II" to differentiate it from classical "lupoid hepatitis" or autoimmune hepatitis type I.

To determine the outcome of chronic hepatitis in ESRD we studied all 358 renal transplant recipients and 295 hemodialysis patients treated for greater than 1 year since 1970. The incidence of chronic hepatitis (elevated SGOT for greater than 1 year) was 15% (N = 54) in transplanted and 3.4% (N = 10) in dialysis patients. Forty-eight percent (26) of transplanted and 50% (5) of dialysis patients were HBsAg positive. In the transplanted group, the clinical outcome of chronic hepatitis was significantly better in HBsAg-negative compared to HBsAg-positive patients; 11% died, none from liver disease, and 32% remitted after a mean follow-up from start of liver disease of 77.3 +/- 8.2 months, whereas in the HBsAg-positive group 54% (14) died, nine from liver disease, and one remitted after a follow-up of 90.2 +/- 8.9 months. Adverse prognostic factors (age, duration of diabetes, and heart disease) present before ESRD treatment began were similar in both groups, as was duration of follow-up. Only 14% (2/14) of HBsAg-negative patients progressed to chronic active hepatitis on liver biopsy compared to 71% (15/21) of HBsAg-positive patients. Histological stability in those with serial biopsies occurred in 66% (4/6) of HBsAg-negative patients, but in only 18% (13/16) of HBsAg-positive patients with a similar duration of follow-up. No dialysis patients died from liver disease. We conclude that chronic hepatitis occurs more frequently in transplanted than dialyzed patients, and that HBsAg-negative chronic hepatitis has a more benign, clinical, and histological outcome than chronic HBsAg-positive hepatitis in renal transplant recipients.

The frequency of fibrosis of the terminal hepatic venule (FTHV) has been investigated by two observers unaware of the patient's history, in needle biopsy specimens showing normal histology (n = 23), alcoholic steatosis (n = 23), steatosis in diabetes or overweight (n = 26), alcoholic hepatitis (n = 21), or virus-related chronic active hepatitis (n = 44). FTHV was coded following a scale from 0 to 3 of severity. Minimal (grade 1) FTHV was seen in most venules of biopsies with a normal histological pattern, and was considered a normal feature. Grade 2 of FTHV was absent in the group showing normal histology but was evident in 17.4%-39.7% of the venules observed in the other groups without attaining diagnostic relevance. The percentage rate of severe (grade 3) FTHV was 0.0, 4.9, 6.6, 18.7 and 2.9 in the respective groups as delineated above. In alcoholic hepatitis, severe FTHV therefore showed a higher frequency than in virus-related chronic hepatitis (p less than 0.001), with high values of sensitivity (0.75), specificity (0.93), and predictivity (0.84 positive, 0.98 negative) for ethanol aetiology. The ethanol-related diagnostic value of FTHV however, was low in steatosis.

One hundred consecutive patients with nonautoimmune chronic active hepatitis (51% HBsAg-positive), 50 patients with cirrhosis (38% HBsAg-positive), 25 patients with chronic persistent hepatitis, and 118 patients with hepatoma who were seen at this hospital were reviewed to determine the prevalence and characteristics of glucose intolerance and diabetes in these conditions. Diabetes (fasting serum glucose greater than 7.8 mmol/L, 140 mg/dl on two separate occasions) was present in 8% of patients with chronic persistent hepatitis and mild chronic active hepatitis, 44% of patients with severe chronic active hepatitis, 40% of patients with cirrhosis, and 15% of patients with hepatoma, compared with 7% of all other patients aged 35 yr or over, undergoing liver biopsy. Compared with this high prevalence of diabetes in liver disease, only 3% of diabetic patients referred to the hospital diabetic clinic had chronic hepatitis or cirrhosis. Glucose tolerance was similar in chronic active hepatitis and cirrhosis and was characterized initially by basal hyperinsulinemia, normal basal glucose levels but elevated serum glucose following glucose loading, and evidence of insulin resistance. We suggest that the high prevalence of diabetes in chronic active hepatitis and cirrhosis in Saudi Arabia is due to the insulin resistance of chronic liver disease acting over many years in a population with a high genetic predisposition to diabetes.

Three patterns of hepatocyte injury in man, direct, immunological, and cholestatic, are described. The characteristics of the direct pattern are predominantly mitochondrial damage, central (zone 3) necrosis, and, usually, fatty change. It can be subdivided into the alcohol type (also seen with obesity, in diabetes, as a reaction to perhexiline, in Wilson's disease, and in Indian childhood cirrhosis) and the Reye's syndrome type (also seen with tetracycline toxicity, fatty liver of pregnancy, and cytotoxic drugs). Reactive drug metabolites, metal poisoning, and anoxia are also associated with the direct pattern of hepatocyte injury. The immunological pattern is characterised by damage to cell membranes with piecemeal necrosis of periportal (zone 1) hepatocytes and mononuclear-cell infiltration. Examples include chronic active hepatitis, primary biliary cirrhosis, and drug reactions such as those to halothane. In the cholestatic pattern there is disturbance of the bile-secretory mechanism with retention of bile within the hepatocytes. Cholestatic liver injury may be intrahepatic, as in sex-hormone cholestasis, or extrahepatic, as in choledocholithiasis or carcinoma of the bile ducts. Identification of the type of hepatocyte injury is valuable in diagnosis, in assessing prognosis, and in selecting treatment.
