One hundred and sixteen cirrhotic patients were prospectively studied over a ten year period. Hepatitis B surface antigen was positive in 70% of tested patients. The cirrhotic liver was mainly macronodular and primary hepatocellullar carcinoma was associated with 63% of the patients. Half of the patients were critically ill with high incidences of ascites, jaundice and encephalopathy. Cirrhotic patients had significantly lower body temperature onycholysis and hyperpigmented palmo-plantar macular areas. The mean survival time was three years from onset of the initial symptoms to death. Patients with concomitant liver cancer were usually dead within six months after onset of the illness. Gender did not substantially affect the course of the disease. The major causes of death were tumour development (63%), gastrointestinal bleeding (40%), haemoperitoneum (28%) and hepatic failure (25%).

This report provides updated information concerning the potential adverse events associated with vaccination for hepatitis B, poliomyelitis, measles, mumps, diphtheria, tetanus, and pertussis. This information incorporates findings from a series of recent literature reviews, conducted by an expert committee at the Institute of Medicine (IOM), of all evidence regarding the possible adverse consequences of vaccines administered to children. This report contains modifications to the previously published recommendations of the Advisory committee on Immunization Practices (ACIP) and is based on an ACIP review of the IOM findings and new research on vaccine safety. In addition, this report incorporates information contained in the "Recommendations of the Advisory Committee on Immunization Practices: Use of Vaccines and Immune Globulins in Persons with Altered Immunocompetence" (MMWR 1993;42[No. 44-4]) and the "General Recommendations on Immunization: Recommendations of the Advisory Committee on Immunization Practices (ACIP)" (MMWR 1994;43[No. RR-1]). Major changes to the previous recommendations are highlighted within the text, and specific information concerning the following vaccines and the possible adverse events associated with their administration are included: hepatitis B vaccine and anaphylaxis, measles vaccine and a) thrombocytopenia and b) possible risk for death resulting from anaphylaxis or disseminated disease in immunocompromised persons; diphtheria and tetanus toxoids and pertussis vaccine (DTP) and chronic encephalopathy; and tetanus-toxoid-containing vaccines and a) Guillain-Barre syndrome, b) brachial neuritis, and c) possible risk for death resulting from anaphylaxis. These modifications will be incorporated into more comprehensive ACIP recommendations for each vaccine when such statements are revised. Also included in this report are interim recommendations concerning the use of measles and mumps vaccines in a) persons who are infected with human immunodeficiency virus and b) persons who are allergic to eggs; ACIP is still evaluating these recommendations.

The impact of dengue haemorrhagic fever (DHF) on liver function was studied by measuring serum transaminase levels on 45 patients with DHF confirmed by virus isolation and serodiagnosis in 1995. Abnormal levels of AST and ALT were observed in 97.7 and 37.3% of the patients, respectively. The fact that the level of AST was higher than that of ALT and that the elevation of transaminases was mild to moderate in most cases (< 5-fold greater than the normal upper limit for AST and ALT) showed that liver involvement was also mild to moderate in most cases of DHF. The results of transaminases did not differ significantly between cases with and without hepatitis B or hepatitis C virus infection, nor between primary and secondary cases of infection, but a significantly higher elevation of AST and ALT was observed in DHF patients with gastrointestinal haemorrhage. Two patients with dengue encephalopathy (in 1992) and one patient with dengue encephalopathy who died of massive gastrointestinal haemorrhage (in 1995) had unusually high transaminase levels as a sign of acute liver failure. It is concluded that DHF may cause mild to moderate liver dysfunction in most cases; only some patients may suffer from acute liver failure leading to encephalopathy and death.

A hospital based observational study was carried out on pregnant women presenting with either acute hepatitis or fulminant hepatic failure (FHF), during the past years. Of 53 patients, 20 (38%) developed FHF.Non-A, Non-B was the commonest cause (62%) followed by hepatitis B in 17% and hepatitis A in 4% cases. Eight women expired (case fatality rate 15%) with a high maternal mortality (62%) caused by NANB hepatitis. Perinatal mortality was 30%. Poor prognostic factors identified were lack of antenatal care, severity of jaundice, history of somnolence, gastrointestinal bleeding and a high grade of encephalopathy.

Three cases of women with chronic liver inflammation caused by hepatitis B (two) and C (one) viral infections, were followed up to twelve years after diagnosis. As conventional therapy was ineffective and the patients progressed into decompensated liver disease, they were superinfected with massive doses of an attenuated variant (MTH-68/B) of the apathogenic avian Bursal Disease virus (a double-stranded RNA virus from the Birnaviridae family). Clinical symptoms and biochemical abnormalities were resolved in two patients following few months of virus treatment. Cirrhosis was stabilized and significant clinical improvement was achieved in the third patient--who before the virus therapy was moribund with recurring, diuretic-resistant ascites, variceal bleedings, portal encephalopathy and renal failure. To our knowledge, these are the first recorded cases of decompensated chronic viral hepatitis which went to long-lasting remission or were stabilized by superinfection with an apathogenic virus.

Acute hepatic failure (AHF) in India almost always presents with encephalopathy within 4 weeks of the onset of acute hepatitis. Further subclassification of AHF into hyperacute, acute and subacute forms may not be necessary in this geographical area, where the rapidity of onset of encephalopathy does not seem to influence survival. Viral hepatitis is the cause in approximately 95-100% of patients, who therefore constitute a more homogeneous population than AHF patients in the West. In India, hepatitis E (HEV) and hepatitis B (HBV) viruses are the most important causes of AHF; approximately 60% of cases are caused by to these viruses. Hepatitis B virus core mutants are very important agents in cases where hepatitis B results in AHF in this country. Half of the patients with AHF admitted to our centre are female, one-quarter of whom are pregnant. Therefore, pregnant females who contract viral hepatitis constitute a high-risk group for the development of AHF. However, the outcome of AHF in this group is similar to that in non-pregnant women and men. No association with any particular virus has been identified among sporadic cases of AHF. In our centre, approximately one-third of AHF patients survive with aggressive conservative therapy, whereas two-thirds of deaths occur within 72 h of hospitalization. Cerebral oedema and sepsis are the major fatal complications. Both fungal and gram-negative bacteria are major causes of sepsis. Among patients with AHF, despite the presence of sepsis, its overt clinical features (i.e. fever, leucocytosis) may be absent and objective documentation of the presence of sepsis in such patients is achieved by repeated culture of various body fluids. It should be possible to develop simple, clinical prognostic markers for AHF in this geographical region, in order to identify patients suitable for liver transplantation.

The general indications for liver transplantation in hepatitis B virus (HBV) and hepatitis C virus (HCV) infection, and the issues surrounding treatment for HBV infection in the pre- and post-transplant periods, are discussed. In general, transplantation is reserved for patients with end-stage liver failure secondary to cirrhosis and a small population with acute liver failure. It is proposed that certain guidelines can be developed and that these should include any one of the following: a Child-Pugh score > or = 9, diuretic resistant ascites, recurrent portal hypertensive bleeding, recurrent encephalopathy, spontaneous bacterial peritonitis and the development of a small hepatocellular cancer (< or = 5 cm in diameter). Treatment for HBV infection now includes lamivudine therapy pre and post transplantation together with hepatitis B immunoglobulin. Such an approach has virtually abolished recurrence of HBV infection following liver transplantation.

Lamivudine is effective in inhibiting hepatitis B virus (HBV) replication, and its clinical use in patients with chronic hepatitis B is associated with improvements in serum aminotransferase levels and liver histopathologic characteristics. Few data are available on its use in patients with advanced liver disease. We report on the outcomes of 5 patients with hepatic decompensation caused by chronic hepatitis B treated long term with lamivudine. All patients were adult white men seropositive for hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) before therapy. All 5 patients had biopsy-proven cirrhosis with clinical and biochemical evidence of hepatic decompensation. Two patients had Child's class C cirrhosis; 2 patients, class B; and 1 patient, class A (although this patient had persistent portasystemic encephalopathy and developed variceal bleeding). HBV DNA became undetectable in all patients and remained so throughout the study. Both patients with Child's class C and 1 patient with class B cirrhosis had significant clinical improvement. Child-Pugh scores improved from 12 to 7 and 11 to 7 in the 2 patients with Child's class C cirrhosis, and the patient with class B cirrhosis had complete resolution of troublesome encephalopathy. Serum aminotransferase, albumin, and total bilirubin levels improved significantly in 3 of 5 patients. One patient with Child's class B cirrhosis underwent orthotopic liver transplantation at week 13 after dramatic increases in liver tests and clinical worsening. The patient subsequently cleared HBeAg and HBsAg from serum posttransplantation. In conclusion, prolonged therapy with lamivudine resulted in improved serum biochemical values and loss of HBV DNA in patients with decompensated cirrhosis. Clinical improvements, reflected in Child-Pugh classification and functional status, may also occur, particularly among those with Child's class C disease initially.

The aim of this study was to evaluate the prognostic factors at presentation and survival in Italian patients with hepatocellular carcinoma (HCC). Clinical and demographic data of 176 patients consecutively observed from 1993 to 1997 were evaluated by univariate and multivariate analyses. Overall median survival was 18 months. At univariate analysis, low albumin, high bilirubin, high alkaline phosphatase, high alpha-fetoprotein (AFP); high platelet count, hepatitis B surface antigen (HBsAg)-positivity, the presence of ascites, of encephalopathy, of portal vein thrombosis (PVT), male sex, no treatment, poor differentiation, untreatable tumours and incidental diagnosis were each associated with shorter survival. HBsAg-positive subjects more often presented with untreatable lesions or diffuse tumours (P=0.001 and P=0.007, respectively) and had significantly worse survival (P=0.0057). By multiple regression analysis, low albumin, high bilirubin, abnormal AFP, presence of PVT and of untreatable lesions were independent risk factors for worse survival. Thus, the most important factors influencing survival are the degree of functional impairment of the liver, the presence of hepatitis B viral (HBV) infection, the type of diagnosis and the aggressiveness of the tumour.
