A 48-year-old woman with type II diabetes developed fatigue, arthralgia and myalgia. A few weeks later she was found to have hepatomegaly. The erythrocyte sedimentation rate was raised (53/93 mm), as were liver enzyme activities (GOT 186 U/l; GPT 240 U/l; gamma-GT 199 U/l), the gamma-globulin levels (40.7%;IgG 4470 mg/dl, IgA 698 mg/dl, IgM 245 mg/dl), antinuclear antibodies and antibodies against double-strand DNA, smooth muscles and actin. Laparoscopy revealed small-nodular liver cirrhosis. The autoimmune hepatitis was treated with prednisolone (initially 60 mg daily, then reduced to 10 mg daily) and azathioprine (initially 100 mg daily, reduced to 50 mg daily). The symptoms markedly improved. But one year later, during follow-up examination, gastric polyps were found, excised and histologically found to be carcinoid. The gastrin level was raised to 765 pg/ml. Another year later the liver cirrhosis had advanced further and the type A gastritis was still present, but there was no sign of carcinoid recurrence.

Hepatomegaly occurring in association with an inhomogeneous liver documented on CT scanning in an individual with abnormal liver injury parameters is a common clinical finding. In most such cases, an increase in the canalicular enzymes (alkaline phosphatase and gamma-glutamyl transpeptidase) is present. Most individuals with this combination of findings are ill-appearing individuals with metastatic cancer. The same findings in an individual with few symptoms or one who appears quite fit is unusual and presents a unique problem in differential diagnosis. Herein we present such a case that, with appropriate medical therapy, had a near complete resolution of the biochemical and radiologic manifestations of disease.

The promoting effect of chlorotrifluoroethylene trimer acid (TRA), a metabolite of the 6-carbon oligomer of Halocarbon 3.1 oil, was investigated using a bioassay designed to detect enzyme-altered foci. These oligomers, as well as their carboxylic acid metabolites, have been shown to cause hepatomegaly and an increased rate of hepatic peroxisomal fatty acid beta-oxidation following administration by oral and inhalation routes. Groups of 2/3 partially hepatectomized male Sprague-Dawley rats were initiated with a single dose of diethylnitrosamine (10 mg/kg). Two weeks later phenobarbital (0.5% in the drinking water) was provided to animals in the positive control group. At the same time, three other groups received an initial dose of TRA by intraperitoneal injection (98, 9.8 and 0.98 mg/kg). Biweekly intraperitoneal injections of TRA (12.3, 1.2, and 0.12 mg/kg) were continued for 9 months. Quantitative sterological analysis revealed that TRA exposure resulted in a significant dose-dependent increase in the number of gamma-glutamyltranspeptidase-positive foci.

Five weeks after a four-day visit to Malta, a 39-year old white male German national developed septic temperatures of up to 40 degrees C, progressive jaundice and a pronounced hepatosplenomegaly. The initial examination showed a very sick, somnolent patient with jaundice, cyanosis, tachypnea and a markedly enlarged liver on both physical examination and sonography. The laboratory evaluation revealed a moderate leukocytosis, markedly accelerated ESR, poor liver function with strongly elevated gamma-GT and alkaline phosphatase levels. Primary antibiotic therapy consisted of doxycycline. Ultrasound examination of the liver four days after admission revealed multiple hypodense abscesses. On the sixth day after admission, gram-negative rods were first isolated from blood cultures; antibiotic therapy was switched to ofloxacin (2 x 400 mg/day) and amoxycillin (3 x 2 g/day) after sensitivity testing. As a result of treatment with this combination of antibiotics, the patient was free of fever 10 days after hospitalization; on the same day yersinia enterocolitica was isolated from the first blood cultures taken on admission. The diagnosis of non-enteric forms of yersinia infection can prove very difficult, especially if the serology is not clear cut and there are no immunological complications. A presentation including intermittent fever, moderate leukocytosis, strongly accelerated ESR and multiple hypodense abscesses in the liver should lead one to consider a non-enteric type of yersinia infection. Hepatic abscesses usually occur in patients who have an iron overload.

We report on 56 children with sclerosing cholangitis (SC) seen between 1972 and 1992. The first symptoms occurred at a mean age of 3.7 years; 15 infants had neonatal cholestatic jaundice. At diagnosis, cholestatic jaundice was present in 25 children, hepatomegaly in 54, splenomegaly in 41, and ascites in 12. Serum alkaline phosphatase activity was increased in 49 patients and gamma-glutamyltransferase activity in all patients tested. Most often the histopathologic findings were extensive portal fibrosis and neoductular proliferation. Cholangiography showed abnormal intrahepatic bile ducts in all children and abnormal extrahepatic bile ducts in 35 (63%). The children were separated into three groups: (1) those with SC of neonatal onset (27%); (2) those with SC of postneonatal onset associated with another disease (55%)--histiocytosis X in 14 children, immunodeficiency syndromes in 8, chronic inflammatory bowel disease or autoimmune hepatitis in 8, and congenital psoriasis in 1; and (3) those with SC of postneonatal onset without an associated disease (18%). Biliary cirrhosis was present in all but three children after 6 months to 19.3 years of follow-up. Eleven children died of portal hypertension or liver failure, and six died of a complication related to the associated disease. Fifteen children had liver transplantation; 11 of these are alive 6 months to 6 1/2 years later without recurrence of SC. The overall estimated median survival time of children with SC was 10 years from clinical onset. These results indicate that SC should be suspected in all children with a chronic cholestatic disease and increased serum gamma-glutamyl transferase activity, especially when diseases known to be associated with SC are present. The prognosis is poor, but liver transplantation should be considered except in those with severe immunodeficiency syndromes.

To examine the effects of ingested snakeweed foliage (SW) on male fertility and reproduction, SW collected at prebloom stage was dried, ground, and mixed with ground commercial rat feed (CRF) as 0, 12.5, and 25% of total diets. Male rats fed SW for 20 d impregnated females as successfully as did dietary controls, but males fed 12.5 or 25% SW for 40 d had seemingly impaired fertility and apparently increased mortality of offspring. Males fed SW for an additional 30 and 42 d showed no differences (P > .05) in serum testosterone or LH concentrations after a GnRH challenge compared with controls. Semen samples collected from the vas deferens revealed that total sperm concentrations were similar (P > .10) between rats fed 12.5 or 25% SW and controls. The percentage of abnormal sperm was higher (P < .01) in rats fed 12.5 or 25% SW for 102 d, compared with the percentage of abnormal sperm in controls (11.5 and 17.8 vs 10.4%), and weight of testes was decreased (P < .05). Dietary SW increased (P < .01) activities of alkaline phosphatase and gamma-glutamyl transpeptidase over those in controls at d 20 (but not at d 98) and hepatomegaly was evident at d 50 and 98. Ingestion of snakeweed foliage by male rats increased abnormal sperm counts, impaired reproduction, and caused hepatotoxicosis.

A huge hepatomegaly was seen in a 30-yr-old female diabetic who was treated with high dose of insulin for her uncontrollable food ingestion. The liver function at the peak of the hepatic enlargement showed a moderate increase of transaminases, alkaline phosphatase, and gamma-glutamyl transpeptidase. The histology of the enlarged liver revealed PAS-positive granules in enlarged hepatocytes, indicating the presence of massive glycogen storage. On admission, she was maintained under a calorie-restricted diet and received approximately 15 to 20 units per day of insulin supplement. At one month after admission, a marked shrinkage of her enlarged liver and restoration of normal liver function were observed concomitantly with the return of fair control of her blood sugar levels. One year later, she had an episode of diabetic ketoacidosis which subsequently was treated with a continuous low-dose infusion of insulin; however, she showed neither hepatomegaly nor liver dysfunction during this episode. There have been 20 cases reported of Japanese diabetics with marked hepatomegaly, in whom the vigorous treatment of diabetic ketoacidosis with insulin seemed to be a trigger of the enlarged liver. This has occurred mostly in patients with insulin-dependent diabetes mellitus. We present a case of non-insulin-dependent diabetes mellitus with glycogen storage hepatomegaly, presumably due to excessive insulin supplements. This suggests that glycogen storage hepatomegaly in diabetics may not be only due to an acute restoration from diabetic ketoacidosis, but may also be due to an overinsulinization in an attempt to maintain a euglycemic condition in spite of excess food intake.

Clinical, haematological and pathological studies were undertaken in Jordan in a stud of 103 racing horses clinically suffering from babesiosis and apparently healthy animals. Out of 47 horses which participated in strenuous exercise, three mares showed sudden onset of immobility and reluctance to move and two mares died. Clinical examination revealed that these five horses (group 1) had fever, anorexia, weakness and severe icterus and, in two mares, haemoglobinuria. Haematological examination revealed that all five horses were heavily parasitized with Babesia equi. This was also found in four horses (group 2) with no evidence of clinical babesiosis. In group 3 (94 horses), neither clinical signs nor B. equi were observed in the blood. The horses in group 1 and 2 recovered after treatment with imidocarb. When the mean values of white blood cell count, red blood cell count, haemoglobin and packed cell volume in group 1 were compared with those for groups 2 and 3, a significant difference was found (P < 0.05). A significant difference was also found when the mean values were compared before and after treatment. Examination of serum total protein, bilirubin and serum enzymes revealed a significant decrease in the mean value of total serum protein (P < 0.05), and a significant increase in the mean values of bilirubin (P < 0.05) in group 1 compared to groups 2 and 3. A significant elevation in the mean value of aspartate aminotransaminase, gamma-glutamyltransferase and creatine phosphokinase and a substantial elevation in the mean value of alkaline phosphatase was also observed in group 1 compared to groups 2 and 3. Postmortem examination of the dead horses showed that the animals had icterus, hepatomegaly and full urinary bladder with deep-red urine. Histopathological examination of the liver showed massive centrilobular degeneration and necrosis. The bile canaliculi and bile ducts were prominent and plugged with dark-brown to canary-coloured bile pigments. The lungs had congestion, oedema, and thrombosis of pulmonary veins. Our results suggest that the horses suffered from B. equal with clinical manifestation following exercise. The clinical, haematological and pathological findings indicate that the animals suffered from haemolytic anaemia which responded to imidocarb therapy.

To study prevalence of cytomegalovirus (CMV) infection in patients with viral hepatitis and its clinical characteristics, serum anti-CMV-IgM was detected in 6411 hospitalized hepatitis cases, and clinical symptoms, signs and liver function in 115 cases with CMV infection were compared with 192 cases of non-CMV infection. Results showed a CMV infection rate of 1.79% in them with an average age of 33.6 years, a sex ratio of 2.13, and dual superinfection with CMV and hepatitis accounting for 44.74%, and triple and quadruple superinfection for 47.37% and 7.89%, respectively. Proportion of those with fever, digestive symptoms, hepatomegaly, changes of gallbladder in ultra sound scan, rising activities of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyltransferase (gamma-GT) were more, and duration of hospitalization longer in the cases with CMV infection. It suggests that CMV can be found in the cases with viral hepatitis, most in a form of dual or multiple infection, and it can aggravate hepatitis.

The aetiology, biochemistry, clinical features and complications of histologically confirmed hepatic cirrhosis in 45 patients (26 females, 19 males) seen at the University Hospital of the West Indies, Jamaica, between 1984 and 1994 are presented. The age range was 1 to 72 years (mean 48 years). Abdominal swelling and weight loss were the commonest symptoms, occurring in 51% and 47% of patients, respectively. Jaundice was a presenting feature in 44%. Hepatomegaly was present in 71% of patients and splenomegaly in 33%. The aetiological factors were: alcohol (36%), bush tea (18%), chronic active hepatitis (11%), drugs (7%), and haemochromatosis (2%). Hepatitis B surface antigen was detected in 2 of 20 patients tested. 24% of the patients also had diabetes mellitus., 29% were anaemic, 29% were thrombocytopenic, 4% were leukopenic, and the prothrombin time was prolonged in 22%. The albumin/globulin ratio was reversed in 71% of the patients. The alkaline phosphatase was elevated in 56%, the aspartate aminotransferase was increased in 58% and the gamma glutamyl transpeptidase in 56%. 56% of the patients had macronodular cirrhosis; the liver showed a micronodular pattern in 18%; 7% had biliary cirrhosis; 7% chronic active hepatitis with cirrhosis; and 13% showed a mixed macro-micronodular pattern. Ascites and fluid overload developed in 44% of the patients. Hepatic encephalopathy occurred in 18% and upper gastrointestinal bleeding in 18%.
