A prospective study of the clinical pattern and course of primary biliary cirrhosis based on the data of 236 patients (211 females, 25 males) in an international randomized trial has been performed mainly using life-table technique. The median follow-up period has been 18 mo. After the entry into the study, at which time the median duration of symptoms was 2.1 yr, the estimated 5-yr increase in the cumulative percentage of patients was for pruritus from 75% to 95%, jaundice 59% to 82%, hepatomegaly 54% to 86%, pigmentation 54% to 85%, xanthomas 27% to 50%, GI bleeding 17% to 46%, ascites 7% to 49%, and vertebral collapse 3% to 20%. The frequency of cirrhosis increased from 30% to 82% in 4 yr. The mitochondrial antibody titer showed a high rate of progression with time. In analysis of subgroups, age, histologic stage, and particularly the serum bilirubin level were important prognostic factors. Sex, duration of symptoms, and character of first symptom or sign had no independent prognostic influence. The most important indication of seriously progressive course was rapid development of severe cholestasis independent of the histologic stage.

Whether prolonged cholestasis is followed by hepatic cirrhosis is still controversial. We have studied two unrelated children who have had cholestasis for 15 years, but neither of whom have developed cirrhosis. Both have severe growth retardation, peculiar facies, pulmonic stenosis, transitory renal tubular acidosis, and vitamin D-resistant rickets. The patients presented in infancy with hepatomegaly and direct hyperbilirubinemia; liver biopsy at that time revealed cholestasis and paucity of bile ducts. Subsequent serial liver biopsies have continued to demonstrate cholestasis, but there has been no evidence of cirrhosis. Electron microscopy has revealed swollen and blunted microvilli of the canalicular membrane of the hepatocyte. The patients have had elevated bile acids in the serum as well as a reversed ration of tri- to dihydroxy bile acids. Treatment with cholestyramine and phenobarbital has brought about symptomatic relief from severe pruritus and excoriation and has lowered the level of serum bile acids, although they are still above the normal range. These findings suggest that cholestasis accompanied by an elevated and reversed bile acid ratio does not universally cause hepatic cirrhosis.

Five cases of hepatic haemangioma are described, and a sixth (previously reported) is reviewed. Clinical features, investigation, and management are described to show the great variability of the complications and prognosis. Five children presented in the first 10 weeks of life with hepatomegaly; 4 developed congestive cardiac failure; 3 had cutaneous haemangiomata. One child presented at age 4 years with hepatomegaly and anaemia, and on investigation had features of chronic disseminated intravascular coagulation. Focal decrease or patchiness in hepatic uptake of technetium-99m colloid, and abnormal intrahepatic circulation was shown in all cases. In 3 children liver biopsy was performed to exclude malignant disease. In one patient there was spontaneous regression of the tumour by age 3 years. In 3 cases hepatic artery ligation was necessary to control congestive cardiac failure which had persisted despite treatment with digoxin, diuretics, and oral corticosteroids, a procedure which was without complications after up to 8 years. One infant with intractable portal hypertension, hepatic vein obstruction, and severe cholestasis died with persisting alimentary haemorrhage and intra-abdominal sepsis. One child aged 4 years showed no immediate response to hepatic artery ligation but the size of her tumour got smaller and the clinical features diminished after irradiation. These tumours cause considerable morbidity and have a high reported mortality. If congestive cardiac failure is not rapidly controlled, hepatic artery ligation should be performed.

Sickle cell intrahepatic cholestasis is a rare but potentially fatal complication of sickle cell disease. Its characteristic features include hepatomegaly, extreme total hyperbilirubinemia, coagulopathy, and acute liver failure. Although the pathophysiology is uncertain, most reports in the medical literature indicate that the prognosis is grim. The only effective therapy that has been reported in this setting is exchange transfusion. We describe two hemoglobin SS patients with sickle cell intrahepatic cholestasis. We conclude that exchange transfusion and supportive care aimed at correction of coagulopathy, stabilization of the acute liver disease, and perhaps most important, avoidance of surgical intervention are the keys to a successful outcome.

Diagnostic laparoscopy continues to have a role in the evaluation and diagnosis of acute and chronic liver diseases, primary and metastatic liver tumors, and peritoneal diseases. We retrospectively reviewed the records of 1794 diagnostic laparoscopies performed at our institution from 1987 to 1992 to identify the indications, results, and safety of this procedure in our training program. A definitive diagnosis was made in 91% of cases with biopsy performed in 93%. Chronic liver disease was evaluated in 890 patients, and a diagnosis was made in 98%. Four hundred thirty-seven patients were evaluated for suspected primary or metastatic carcinoma, and a diagnosis was made in 85%. Ascites was evaluated in 73 patients, and a diagnosis was made in 82%. One-hundred sixty-four patients were evaluated for abnormal liver function tests, and a diagnosis was made in 91%. HIV-related liver function test abnormalities were evaluated in 67 patients, and a diagnosis was made in 81%. One hundred sixty-three patients underwent diagnostic laparoscopy for the evaluation of hepatomegaly, splenomegaly, unexplained portal hypertension, fever of unknown origin, and cholestasis, and a diagnosis was made in 74% of cases. Eight major complications (including abdominal viscus perforation, hemobilia, splenic laceration, bleeding) and thirty-one minor complications were seen. Our findings confirm that diagnostic laparoscopy is a safe and valuable procedure in the evaluation of chronic liver disease.

The records of 52 children with Niemann-Pick disease type C were reviewed to establish whether the disease process and outcome varied with the initial clinical pattern; 34 children (65%) had cholestatic liver disease and hepatosplenomegaly in infancy; 18 were seen at a mean age of 4 years with splenomegaly or neurologic disease or both. Of the 34 children with early cholestatic liver disease, three died in the neonatal period; cholestasis and hepatomegaly subsided in the remaining 31 children, although splenomegaly persisted. Of these 31 children, 15 had persistent liver disease with elevated aminotransferase values. Serial liver biopsy specimens showed that 3 of the 15 children had normal architecture and 12 had hepatic fibrosis, with progression to cirrhosis in 5. No other significant morbidity or additional deaths were associated with the liver disease. The clinical importance of persistent liver disease was overshadowed by the subsequent development of severe neurologic disease. There was no difference in the age at onset of the disease (mean, 4.5 years) or in the pattern of neurologic disease, including supranuclear ophthalmoplegia, whether or not the child had early liver disease. Overt neurologic disease has not yet developed in seven surviving children with liver disease at onset. Sixty-seven percent of children died during the study; the main cause of death was bronchopneumonia. We conclude that the diagnosis of Niemann-Pick disease type C should be considered in patients with unexplained neonatal hepatitis, especially if splenomegaly is a persistent feature. Because liver biopsy specimens may not demonstrate storage cells, bone marrow aspiration to detect the characteristic storage cells is recommended in such patients.

A study of the clinical profile of 59 patients who presented with hepatitis A virus infection showed that dark urine, fatigue, gastrointestinal complaints, and fever were the most common presenting symptoms. The most frequent physical findings were hepatomegaly and jaundice. The mean presenting laboratory tests included total bilirubin of 5 mg/dL, alkaline phosphatase of 269 units/L, and serum aspartate aminotransferase and alanine aminotransferase levels of 1442 mIU/mL and 1952 mIU/mL, respectively. Atypical manifestations included relapse, cholestasis, rash, and arthralgia. Two patients presented with hepatitis A and concomitant type I autoimmune chronic hepatitis, and both required immunosuppressive therapy. Five patients who presented with hepatitis A were pregnant, and during follow-up, none of their infants developed elevated serum transaminase values or had detectable IgM anti-HAV antibody. All 59 patients experienced complete clinical and biochemical recovery within 6 months after onset of illness.

A 4-week-old male infant was admitted to the hospital with acute gastrointestinal bleeding and marked coagulopathy secondary to vitamin K malabsorption in the presence of cholestasis. Physical examination revealed hepatomegaly and cutaneous haemangiomas. Ultrasonography, CT, and MRI demonstrated a multifocal vascular process and allowed the diagnosis of infantile hepatic haemangioendothelioma to be made without the use of more invasive diagnostic procedures. To avoid high-output congestive heart failure, the patient was treated with oral corticosteroids. After 5 months, rapid involution of the vascular malformations ensued. At age 2 years, a magnetic resonance scan confirmed complete resolution of the hepatic haemangioendothelioma.

Epidemiological, clinical, biochemical and topographic features of primary hepatic cancer (PHC) were reviewed retrospective and prospectively in this study. This review consisted of 76 patients from 1971 to 1990. Forty nine males and 27 females. The mean age was 66.1 +/- 11.7 years. Hepatocellular carcinoma (HC) was the most frequent histological type (84.1%), followed by cholangiocarcinoma (87.7%). Mixed carcinoma and hepatoblastoma were 4.3 and 2.9% respectively. The prevalence af PHC among 1485 autopsies was 0.74%. The most frequent sites af metastasis were the lungs (66%) and portal vein (50%). Hepatocellular carcinoma was associated to cirrhosis in 80% of the cases. A syndrome including asthenia, weight loss, hepatomegaly and cholestasis was identified in most of the patients, and alkaline phosphatase was the most frequently disturbed laboratory test. 60% of tumors were bilateral and none of the solitary tumors had less than 5 cms in diameter. 20% of HC showed normal serum levels of AFP (< 20 ng/ml). 40% had at least one of the markers of B virus hepatitis in serum.

The clinical and pathological features of four liver biopsies and 12 autopsies from 1981-1990 with hepatic amyloidosis were reviewed. All of the patients had a history of both intravenous and subcutaneous cocaine and heroin use with chronic suppurative skin ulcers. Five patients were proven to have the acquired immunodeficiency syndrome at autopsy. Systemic amyloidosis was diagnosed in only five out of the 16 patients prior to death. Hepatomegaly was present in 12 patients. The amyloid protein was AA in 14 and AL in one case. Definitive characterization of the amyloid substance was not possible in one case. There was no evidence of multiple myeloma or a plasma cell dyscrasia in the one patient with AL amyloid. The amyloid distribution in the liver was both parenchymal and vascular in 12 cases. Cholestasis, which appeared to occur preterminally, was the only histological finding that correlated with the patient's clinical condition. The histological pattern of amyloid in the liver could not predict the type of amyloid protein that was identified. Amyloidosis should be considered in the differential diagnosis of unexplained hepatomegaly in the acquired immunodeficiency syndrome with chronic suppurative infections.
