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%.

Recent advances in serodiagnosis of hepatotropic viruses have revolutionized the approach to diagnosis and understanding of chronic liver disease (CLD). There are few studies on CLD in children from India. The present study was planned to define the clinical spectrum of CLD in children, its histopathology and seroepidemiology. Forty children with clinical features satisfying the criteria for diagnosing chronic liver disease were studied. All underwent routine laboratory investigations, liver function tests and ultrasound scan of the abdomen. Liver biopsy, upper GI endoscopy and other special investigations were done wherever indicated. The most common presenting features were jaundice (70%), fever (67%), and abdominal distention (60%). On examination hepatomegaly and icterus (80% each) and splenomegaly (67%) were the commonest findings. Serum transaminases were raised in 62.5% of children while prothrombin time was prolonged in 75% patients. Oesophageal and/or gastric varices were seen in 13 out of 29 patients subjected to upper GI endoscopy. Hepatitis B surface antigen (HbsAg) was positive in 5 children (12.5%) while 3 (7.5%) tested positive for anti HCV antibody. The commonest histopathological diagnosis was infantile cholangiopathy (20%) followed by cryptogenic cirrhosis and idiopathic chronic active hepatitis (17.5% each). The study suggests that the incidence of chronic hepatitis B and C is rather low in childhood. However larger and longer studies are required to delineate the exact incidence of these conditions in childhood and their progression in adolescence and early adulthood.

Two hundred and fifty two blood donors HBsAg positive (mean age = 32.6, 91, 7% male) were searched into a transversal study to determine their clinical, laboratorial and histological characteristics. It was also compared the positiviness and negativiness of the serologic markers HBeAg, anti-Hbe and IgM anti-HBc with the values of serum aminotransferases. Hepatomegaly and splenomegaly were detected in 9.9% (25/252) and in 2.4% (6/252) respectively. In 17.5% (44/251) and 28.3% (71/251) the AST and ALT were respectively, over 50 UI/I. The positive frequencies of the various serologic markers of hepatitis B virus in 120 patients were: anti-HBc total in 89.5% (102/114), HBeAg in 25.7% (28/109) anti-Hbe in 67.3% (66/98), IgM anti-HBc in 40.8% (49/120); anti-Delta in 0.0% (0.66). Thirty one patients were submitted to liver biopsy, due do clinical alteration and/or of the aminotransferases. The hystological findings were: normal liver in 16.1% (5/31), non specific hystological alterations in 22.6% (7/31), persistent chronic hepatitis in 22.6% (7/31), active chronic hepatitis in 6.5% (2/31), cirrhosis in 12.9% (4/31), alcoholic hepatitis in 3.2% (1/31), lobular chronic hepatitis in 3.2% (1/31) and alterations exclusively due to schistosomiasis in 12.9% (4/31). Schistosomiasis elements (granuloma and/or Symmers fibrosis) were also notived in 7 patients. The comparative analysis of positiveness and negativeness of the serologic markers with the aminotransferases ("t" test of Student) showed significative difference of the averages (p < 0.05) only in relation to the simultaneous positeveness and negativeness of the HBeAg and IgM anti-HBc (average of AST = 56.11 and ALT = 78.00 when HBeAg and IgM anti-HBc were positive; average of AST = 24.25 and ALT = 27.00 when HBeAg and IgM anti-HBc were negative). According to this study the conclusion are: 1) The presence of two markers (HBeAg and IgM anti-HBc) and not only one determinant of viral replication in asymptomatic HBsAg carriers can strongly indicate a significant biochemical activity suggestive of hepatocellular lesion. 2) The presence of HBeAg in 25.7% (28/109) clearly shows the high rate of carriers with a potential of infectivity. 3) The results of hepatic histology shows that the majority of our patients had either normal liver or mild histological alterations. It is important to notice that only the cases with elevated aminotransferases were submitted to liver biopsies. The alterations caused by schistosomiasis shows, as is well known, the high prevalence of the parasitism in our surroundings. 4) The clinical aspects of the patients studied did not show significant alterations. Risk factors to get the infection were low. The hematologic and biochemical parameters (except aminotransferases) were either normal or just slightly abnormal. It was not detected a statistically significant difference. 5) The co-infections by delta virus was null.

Between 1992 and 1997, 790 blood donors with anti-HCV EIA-2 strongly reagent (relationship between the sample optical density/cut-off > 3) detected at the blood bank serological screening, were evaluated in ambulatory environment. They were all negative for Chagas disease, syphilis, hepatitis B (HBsAg) and AIDS. Blood samples were collected at the first ambulatorial evaluation, for hemogram, biochemical tests and new serological tests for HCV (anti-HCV EIA-2). In blood samples of 226 repeatedly reagent anti-HCV EIA-2 blood donors, supplementary "immunoblot" test for HCV (RIBA-2) was used. In 209 donors, the presence of HCV-RNA was investigated by the PCR test. The abdominal ultrasonography was realized in 366 donors. In 269 patients liver biopsy was performed for the histopathological study. The follow-up of blood donors showed that 95.6% were repeatedly EIA-2 reagent, 94% were symptomless and denied any hepatitis history, with only 2% mentioning previous jaundice. In 47% of this population at least one risk factor has been detected for the HCV transmission, the use of intravenous drugs being the main one (27.8%). Blood transfusion was the second factor for HCV transmission (27.2%). Hepatomegaly was detected in 54% of the cases. Splenomegaly and signs of portal hypertension have seldom been found in the physical examination, indicating a low degree of hepatic compromising in HCV. Abdominal ultrasound showed alterations in 65% of the subjects, being the steatosis the most frequent (50%). In 83. 5% of the donors submitted to the liver biopsy, the histopathological exam showed the presence of chronic hepatitis, usually classified as active (89%) with mild or moderate grade in most of the cases (99.5%). The histopathological exam of the liver was normal in 1.5% of blood donors. The RIBA-2 test and the HCV-RNA investigation by PCR were positive in respectively 91.6 and 75% of the anti-HCV EIA-2 reagent donors. The HCV-RNA research was positive in 82% of the RIBA-2 positive subjects, in 37.5% of the indeterminate RIBA-2 donors and in 9% of the negative RIBA-2 donors. Chronic hepatitis has also been observed in 50% of the histopathological exams of the anti-HCV EIA-2 reagent donors which were indeterminate RIBA-2. Among 18 blood donors with minimal changes histopathological exam 11 (61%) were HCV-RNA positive. Our blood donors anti-HCV reagent generally had clinical, laboratorial and histopathological features observed in patients with chronic HCV hepatitis and a high proportion could be identified in interviews and medical evaluation realized in blood blanks. Generally, these HCV infected donors are identified and discharged only by the serological tests results.

Knowledge about synthesis of thrombopoietin (TPO) by human liver cells is now well established and makes the study of TPO serum levels and interdependency with platelet concentrations important before and after liver transplantation. We followed these variables in 14 patients suffering from primary biliary cirrhosis (group A), 10 with hepatitis B (group B) and nine with hepatitis C (group C) infections, as well as 11 patients suffering from alcoholic cirrhosis (group D). In the pretransplant serum samples, TPO levels and platelet counts revealed median values (range) of 112.75 pg/ml (5.0-349.3) in group A, 67.8 pg/ml (14.8-249.9) in B, 68.6 pg/ml (31.4-147.3) in C and 57.9 pg/ml (25.2-264.2) in D for TPO, and 138 x 10(9)/l (36-243) in A, 48 x 10(9)/l (22-129) in B, 105 x 10(9)/l (32-176) in C and 109 x 10(9)/l (33-285) in D for platelets, the latter levels being abnormally reduced. Within 2-3 d of transplantation, the TPO levels started to increase to transient peaks of mostly 5-10 times baseline, which were followed by continuous correction of thrombocytopenia. Splenomegaly was identified to be an important co-factor of thrombocytopenia in groups A and D. We conclude that decreased TPO production in patients with end-stage liver diseases is reverted by orthotopic liver transplantation.

48 patients with liver fibrosis due to hepatitis B were treated for 2 years with the drugs for tonifying the kidney, supplementing qi, cooling and invigorating the blood and detoxification. The symptoms were markedly improved, and serum ALT and bilirubin were recovered and kept normal in most of the cases. The mean levels of serum hyaluronic acid, procollagen peptide III and circulating immune complex were decreased and returned to normal after the treatment. B-ultrasonography showed that the portal vein kept in normal size in 82% of the patients, the enlarged portal vein diminished in diameter, and the enlarged spleen reduced.

Childhood primary hepatocellular carcinoma is rare and accounts for less than 1% of all abdominal malignancies in children < or = 14 years of age. A review of the records of the Cancer Registry, Ibadan, Nigeria covering the period 1960-1995 was scrutinised and 19 cases of hepatocellular carcinoma (HCC) were registered, accounting for 0.49% of all abdominal malignancies over the period of review. The mean (SD) age at presentation was 10.4 (3.0) years and the duration of illness before presentation was short. All the children presented late with abdominal distension and hepatomegaly as the major clinical features. Weight loss was evident in 80% of cases, splenomegaly occurred in 50% and jaundice was present in a third of them. The prognosis was poor; all the cases died within 2 weeks of presentation in hospital. There was evidence to suggest an association between hepatitis B virus infection and HCC in all the liver tissue stained by Shikata-Orcein. This review shows that HCC, though uncommon, is important enough to be considered a possible cause of unexplained hepatomegaly in Nigerian children and that hepatitis B virus is an important aetiological factor. Though the number of cases under review is small, universal early vaccination against hepatitis B virus is necessary in Nigerian children in order to reduce the burden of chronic hepatitis B disease and hepatocellular carcinoma.

Hepatitis C virus (HCV) is considered the most common etiology of chronic liver disease (CLD) in Egypt, where prevalence of antibodies to HCV (anti-HCV) is approximately 10-fold greater than in the United States and Europe. Reported are results that show the role of HCV in both overt and occult CLD, the risk factors for CLD and for HCV infection, and the relative importance of chronic HCV, hepatitis B, or both in causing hepatic morbidity. Case patients included 237 new outpatients at the National Liver Institute. Controls comprised 212 sex- and age-matched neighbors without liver disease. Case patients were more likely than controls to report a history of blood transfusions, schistosomiasis, or parenteral therapy for schistosomiasis; to have anti-HCV, HCV RNA, hepatitis B surface antigen, and serum alanine aminotransferase (ALT) elevations; and to have abdominal ultrasound findings of cirrhosis, portal hypertension, and splenomegaly. Anti-HCV-positive case patients were more likely than anti-HCV-negative patients to be male, older, and farmers: to have received a blood transfusion or parenteral therapy for schistosomiasis; to have ALT elevations; and to have ultrasound findings of cirrhosis, portal hypertension, and spleen enlargement. Anti-HCV-positive controls were more likely than anti-HCV-negative controls to have received parenteral therapy for schistosomiasis. These data support the belief that HCV is the predominant cause of CLD in Egypt and suggest there is a large underlying reservoir of HCV-caused liver disease.

DNA rich in nonmethylated CG motifs (CpGs) greatly facilitates induction of immune responses against coadministered Ags. CpGs are therefore among the most promising adjuvants known to date. Nevertheless, CpGs are characterized by two drawbacks. They have unfavorable pharmacokinetics and may exhibit systemic side effects, including splenomegaly. We show in this study that packaging CpGs into virus-like particles (VLPs) derived from the hepatitis B core Ag or the bacteriophage Qbeta is a simple and attractive method to reduce these two problems. CpGs packaged into VLPs are resistant to DNase I digestion, enhancing their stability. In addition, and in contrast to free CpGs, packaging CpGs prevents splenomegaly in mice, without affecting their immunostimulatory capacity. In fact, vaccination with CpG-loaded VLPs was able to induce high frequencies of peptide-specific CD8(+) T cells (4-14%), protected from infection with recombinant vaccinia viruses, and eradicated established solid fibrosarcoma tumors. Thus, packaging CpGs into VLPs improves both their immunogenicity and pharmacodynamics.
