Cholestasis in early infancy produces reactive alterations of liver parenchyma within the first weeks of life; histological examination of liver biopsy specimens may give hints as to the underlying disease. Differentiation of bile duct atresia and giant cell
hepatitis
at an early stage is especially important. Hyperplasia of the intrahepatic bile duct system can be due to rather different diseases. Congenital abnormalities of the duct system can be distinguished from reactive alterations only by early liver biopsy. Certain histological changes may give evidence of congenital or other metabolic disorders.
Hemochromatosis
of the neonatal period has been characterized morphologically but not as yet biochemically.

33 patients with chronic renal failure were divided into two groups. Group I consisted of 8 non-dialysed patients without any clinical or biochemical sign of liver disturbance nor any iron supplementation. Group II consisted of 25 maintenance hemodialysis (MHD) patients treated from 2 to 13 years. 19 subjects had chronic B
hepatitis
. Total exogenous iron load parenteral iron and/or blood transfusions) was calculated. Body iron overload (hemosiderosis) was assessed by liver iron concentration (LIC) in needle biopsy specimens according to Barry's method (less than 200 microgram/100 mg dry weight) and serum ferritin levels (less than 360 ng/ml). 4 patients whose serum ferritin was increased with or without hepatic fibrosis and with or without any organ dysfunction due to hemochromatosis received i.v. infusions of desferrioxamine in doses of 2 g at each dialysis. Serum ferritin levels were correlated with LIC (p less than 0.001) and iron load (p less than 0.001). Hemosiderosis was noted in 16 MHD patients (group II) and correlated with iron load.
Hemochromatosis
was noted in 4 patients (group II). 4 hemodialysed patients with iron overload were treated by desferrioxamine from 6 to 18 months. During this therapy, body iron stores fell and organ dysfunction (heart failure, hepatic cytolysis, anaemia, diabetes mellitus improved. Long-term chelation therapy by desferrioxamine was effective and the chelated iron was readily removed by dialysis. These data show the importance of precise evaluation of iron stores in MHD patients.

Hepatitis B virus (HBV)- and hepatitis C virus (HCV)-related liver damage is linked to an increased risk of hepatocellular carcinoma, but the mechanisms underlying hepatitis C viral activity are not known. We therefore compared hepatocellular proliferative activity in chronic C virus-related
hepatitis
and in liver damage of other etiology. Hepatocyte proliferation rate was investigated in 56 patients with chronic hepatitis using the Ki67 MIB1 monoclonal antibody in archival material. According to etiology, the patients were subgrouped as follows: HCV (34), HBV (11), Alcohol (4), HCV + Alcohol (4), and
Hemochromatosis
(3). Proliferation rate was correlated with age, sex, etiology, disease activity, liver iron storage, free-radical production, and glutathione levels by regression and discriminant analysis. HCV-positive patients had significantly more MIB1-positive hepatocytes in the periportal area (P < .011) and in the low-proliferating perivenular area (zones 2 and 3) (P < .05). The number of MIB1-positive cells correlated directly with alanine transaminase (ALT) levels, Knodell index (KI), and, inversely, with iron saturation. By stepwise discriminant analysis, ALT levels and etiology were identified as single independent variables. These data suggest that HCV infection induces increased and abnormal hepatocyte proliferation, which might be related to the increased risk of hepatocellular carcinoma in patients with HCV-related liver damage.

A possible link is suggested between hepatic diseases and rheumatic disease. Polyarthralgia and polyarthritis may be seen during the prodromal period of acute viral hepatitis, especially in hepatitis B virus (HBV). The symptoms of arthritis, mild, localized or generalized, mostly involve the small joints of hands. Joint symptoms frequently precede the onset of jaundice, no residual joint deformities. Circulating immune complexes are believed to play a causative role in the development of vasculitis and arthritis.
Hemochromatosis
is an antosomal recessive disorder of iron. About 43%-81% of patients with hemochromatosis have arthritis. The common extrahepatic manifestations of autoimmune
hepatitis
are arthralgia and skin rash. The reported prevalence of symptomatic inflammatory arthropathy in patients with primary biliary cirrhosis ranges from 4% to 50%. Skeletal involvement with Wilson's disease is common. Such patients may complain of pain and stiffness, mainly in the knee, wrist, or other large joints. Shwachman's syndrome is a disorder of pancreatic exocrine. Symmetric bone lesions have been reported in 10% to 15% of patients. They are involved predominantly at the femoral neck. Rheumatic symptoms are seen in one third of adult patients with cystic fibrosis and arthritis in 2.5% to 12% of patients. The arthritis caused by pancreatic panniculitis is usually symmetrical and involves the small joints of the hand, wrist, and feet, but may involve such larger joints as the elbow, ankle, and knee.

Most studies on health related quality of life (HRQoL) of chronic liver patients were done in small clinical populations or restricted to one aetiology or disease stage. There is still a need for a study in a large liver patient population with various aetiologies and disease stages, approaching a population-based study. We evaluated the impact of liver disease aetiology on generic HRQoL, disease-specific HRQoL and fatigue and we compared HRQoL and fatigue between aetiological groups and healthy Dutch controls. Members of the Dutch liver patient association completed the Liver Disease Symptom Index, Short Form-36, and Multidimensional Fatigue Index-20. We compared the HRQoL between patients with viral hepatitis, autoimmune
hepatitis
, cholestatic diseases, hemochromatosis and other liver diseases by linear, ordinal and logistic regression, corrected for disease stage and other significant factors. Viral hepatitis patients showed a worse mental health than other aetiological groups.
Hemochromatosis
patients demonstrated 17% more bodily pain than viral hepatitis patients and the strongest decrease in role emotional health with increasing age. Aetiological groups showed a worse generic HRQoL and more fatigue than controls. In conclusion, viral hepatitis and hemochromatosis patients have a more impaired HRQoL than patients of other liver disease aetiological groups.
