Chronic obstructive liver disease and secondary hyperlipidemia developed in an immunodeficient boy. Sequential addition of cholestyramine and phenobarbital to his medical regimen, following an initial response to bile drainage, resulted in the disappearance of xanthomas and pruritus, and the restoration of normal serum concentrations of lipids and bile acids. This improvement may result from shifting the bile acid pool from the peripheral blood compartment to the enterohepatic circulation.

Among 424 children with liver disease, 20 had alpha1-antitrypsin deficiency associated with protease inhibitor ZZ phenotype. This disorder manifested itself as cholestasis in early infancy in 19 children. Jaundice and pruritus cleared in 16 of these by 7 months of age, but hepatomegaly and laboratory evidence of mild hepatic dysfunction persisted in all. Biliary cirrhosis and portal hypertension eventually developed or was suspected in eight, and hypoplasia of intraheptic bile ducts was demonstrated in another four. Routine screening revealed intermediate alpha1-antitrypsin deficiency in 16 other children with various types of liver disease. The phenotype in these patients was MZ, MS, or SZ. PAS-positive granules were present in liver of all patients with the ZZ phenotype and in none with other phenotypes. The findings indicate that manifestations and prognosis of this inherited liver disease are extremely variable.

Problems of pregnancy in patients with liver disease are discussed. The effects of pregnancy on the disease course are generally limited to triggering of intensifiying icterus and pruritus; intrahepatic cholestasis may also occur. Increased incidences of miscarriage and prematurity have been reported in patients with liver cirrhosis, chronic hepatitis, cholestasis, and Dubin-Johnson syndrome, which is hereditary, and viral hepatitis in early pregnancy (increased incidence of chromosome abnormalities). Liver diseases constitute a relative indication for abortion, depending on the general state of the mother's health and her desire for the child. Problems of diagnosis and treatment are also considered.

The clinical and laboratory findings in 32 patients with erythropoietic protoporphyria as well as a review of the pertinent literature on this relatively recently described form of porphyria are presented. The disease is thought to be transmitted in an autosomal dominant fashion with variable penetrance and was characterized in these 32 patients by the onset in childhood of burning (97 per cent) and itching (88 per cent) of the skin on exposure to sunlight. This was accompanied by edema (49 per cent) and erythema (69 per cent) of the exposed areas. Vesicles, petechiae and residual scarring occurred less frequently. Associated abnormalities included cholelithiasis (12 per cent), anemia (27 per cent) and abnormal liver function studies (4 per cent). Reports of associated liver disease including nine cases of fatal hepatic failure, are reviewed. Current methods of diagnosis as well as theories of pathophysiology of the disease are presented. Nineteen of 23 of these patients recently treated with beta-carotene responded with significant increase in their tolerance to sun exposure.

In two patients intrahepatic cholestasis and cholestatic liver disease probably due to N-propyl ajmaline were observed. In both cases there was a four-week-interval between the first ingestion of the drug and the onset of jaundice. In one case with rigors there was a temporary rise in temperature and cholestasis. In the other there was a two to three week prodromal period of pruritus and gastro-intestinal symptoms. Both cases were characterised by blood and pronounced tissue eosinophilia in the periportal zones, a marked increase of cholestatic and hepatic cell enzymes, serum bilirubin and cholesterol, a moderate increase in erythrocyte sedimentation rate and absence of leucocytosis. Pathological laboratory findings returned to normal spontaneously within 5 weeks in one case and within two weeks under steroid therapy in the other.

Phototherapy has been used to treat neonatal jaundice, but little assessment has been made of possible beneficial effects on adult liver disease. Effects of phototherapy on bile acid turnover, biliary lipid concentration, liver function tests, and bromosulfophthalein (BSP) kinetics were studied in 8 alcoholic cirrhotics. Phototherapy initially increased biliary specific activity of both primary bile acids and then produced an acceleration of cholic and chenodeoxycholic acid decay curves. Pruritus was relieved in the 3 patients who had this symptom. The proposed mechanism for these changes is mobilization of bile acids from an expanded cutaneous bile acid pool with augmented bile acid excretion. No significant change in serum liver function tests or BSP plasma disappearance curves was seen. Phototherapy causes little improvement in intrinsic liver function, but produces specific changes in bile acid metabolism; these changes may be related to effects of light on a cutaneous bile acid pool.

The efficacy of plasma perfusion through a new anionic resin, BR-350, for palliation of intractable pruritus secondary to intrahepatic cholestasis was studied in four patients. The treatment was given in a daily 2-h session on 3 consecutive days and was followed by repeated treatment periods each 3rd to 4th week. The patients experienced symptomatic improvement during the first treatment period, and the treatment was well tolerated. Adsorption of bile acids across the filter was efficient and resulted in a bile acid concentration gradient pre- to post-resin of 92%. Thus plasma perfusion through the ion resin BR-350 is an effective and safe treatment for symptomatic relief of intractable pruritus in cholestatic liver disease and may reduce hospitalization time and increase the quality of life.

The 2-oxo-acid dehydrogenase family of enzymes have been identified as the major mitochondrial autoantigens of primary biliary cirrhosis. Using immunoblotting, enzyme-linked immunosorbent assay and enzyme inhibition with both purified mitochondrial proteins and recombinant autoantigens, we have studied family members and spouses of patients with primary biliary cirrhosis for the presence of antimitochondrial antibodies. Antimitochondrial antibodies and other common autoantigens were also tested for by indirect immunofluorescence. This study included 27 index patients with primary biliary cirrhosis, 15 spouses and 48 first- and second-degree relatives. Overall, 7 relatives (11%) were positive for autoantibodies to nuclear and cytoplasmic antigens by indirect immunofluorescence against mouse liver and stomach sections. However, with immunofluorescence, the reactivity strictly paralleled that of antimitochondrial antibodies in only one of these (1:640)--a sibling with mild pruritus and a liver biopsy specimen diagnostic of primary biliary cirrhosis despite normal levels of serum alkaline phosphatase. In addition, one of the mothers, who had a history of sarcoidosis, was positive by immunoblotting for antibodies to the E2 subunit of the pyruvate dehydrogenase complex and protein X. All other relatives were negative for all of the assays. Antibodies to neither the 2-oxo-acid dehydrogenase enzymes nor the recently proposed family of naturally occurring mitochondrial antibodies were found in spouses or healthy relatives. Three other first-degree relatives suffered from liver disease: two died (one from primary biliary cirrhosis and the other from an unknown type of liver disease) and one (a sibling with primary biliary cirrhosis) was unavailable for testing. Our results are consistent with a familial predisposition to primary biliary cirrhosis.(ABSTRACT TRUNCATED AT 250 WORDS)

A 39-year-old woman was evaluated for possible liver transplantation due to rapidly developing hepatic failure 4 weeks after initiation of oral minocycline 100 mg twice a day for the treatment of acne. The patient developed a maculopapular rash, malaise, fever, nausea, and vomiting 2 weeks prior to admission to the hospital. On admission, her symptoms rapidly progressed to liver failure characterized by rapidly rising liver enzyme levels, worsening encephalopathy, and coagulopathy. Viral hepatitis serologies and blood cultures were all negative. After intensive supportive care for 2 weeks, the patient's condition gradually improved and she was discharged with mildly elevated liver enzyme levels and pruritus, without need of liver transplantation. Minocycline-induced hepatic injury is an idiosyncratic reaction with a sensitization period that appears to be 3-4 weeks in duration. The characteristic features include rash, fever, lymphadenopathy, and eosinophilia, as well as severe alterations in liver function. The high liver enzyme levels and the significant prolongation of the prothrombin time suggest massive hepatocellular damage. In light of the profound liver damage that occurs with this adverse reaction, care should be taken in administering minocycline to patients who have concomitant liver disease. It is recommended that patients should be instructed as to the possible signs and symptoms of toxicity and be monitored for evidence of idiosyncratic reaction or liver failure.

Two siblings (a 2-year-old female and 11-month-old male) with similar onset of obstructive jaundice and clinical manifestations from early infancy are described. The jaundice fluctuated but never completely disappeared. Abnormal amounts of cholate, chenodeoxycholate and ursodeoxycholate were found in serum bile acid fractions. Pruritus, hyperbilirubinemia of predominantly the conjugated fraction and bilirubinuria were increased by repeated respiratory infections. Ultrasonography showed several highly echogenic shadows in the gallbladder in both cases, and gallstones were found at surgery. Operative cholangiography showed an anomalous arrangement of pancreaticobiliary ductal system in both cases. The pedigree showed five relatives (including the father) on the paternal side had liver disease, and an autosomal recessive inheritance was suggested. The association of familial intrahepatic cholestasis with a large amount of serum bile acids (which seem to be due to abnormal bile acid metabolism), cholelithiasis and anomalous arrangement of the pancreaticobiliary ductal system is proposed as a new hepatobiliary syndrome.
