Abstract
BACKGROUND Serum fibrosis markers are useful in staging chronic hepatitis B (HBV) and C (HCV) virus but have not been evaluated in chronic hepatitis D virus (HDV). AIM To evaluate the utility of serum fibrosis markers [fibrosis-4 score (FIB-4), aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio, aspartate aminotransferase ratio (AAR), age-platelet index (API), AST-to-platelet-ratio-index (APRI) and Hui score] in HDV infection. METHODS Clinical and histologic laboratory data from HBV, HCV and HDV patients were evaluated and serum fibrosis markers were calculated. The ability of fibrosis markers to detect advanced fibrosis (Ishak ≥4) and cirrhosis (Ishak = 6) were evaluated and compared between viral infections. RESULTS A total of 1003 subjects (HCV = 701, HBV = 240 and HDV = 62) with mean age of 46 ± 11 and 66% male were evaluated. HDV subjects had higher ALT and AST than HCV and lower platelets than both HBV and HCV. Histologically, HDV had the greatest percentage of Ishak ≥4 and necroinflammation. FIB-4 performed best in detecting advanced fibrosis and cirrhosis in all viral cohorts. In HDV, area under the receiver operator curve (AUROC) 95% confidence intervals for detecting advanced fibrosis were: FIB-4 = 0.70 (0.55-0.84), API = 0.69 (0.55-0.82), APRI = 0.68 (0.54-0.82), Hui score = 0.63 (0.49-0.78), AAR = 0.63 (0.48-0.77). The AUROC for detecting cirrhosis in HDV were: FIB-4 = 0.83 (0.69-0.97), API = 0.80 (0.66-0.95), APRI = 0.75 (0.61-0.89), Hui score = 0.70 (0.49-0.91) and AAR = 0.70 (0.48-0.93). Adjustment of published cut-offs led to marginal improvements in FIB4 for advanced fibrosis and of APRI for cirrhosis in HDV. CONCLUSIONS Serum fibrosis markers have lower performance accuracy in chronic HDV infected patients compared to HBV and HCV patients. Other noninvasive fibrosis markers should be explored to assist in the management of these patients.

Abstract
Objective: To report a case suggesting the beneficial effect of adefovir dipivoxyl in patients with delta-related decompensated liver cirrhosis ineffectively treated with lamivudine. Case Summary: A 55-year-old woman with chronic hepatitis B virus (HBV), antihepatitis Be positive, and hepatitis delta virus (HDV)–related decompensated liver cirrhosis (Child–Pugh score B9) was awaiting liver transplantation. During this time, she was treated with lamivudine 100 mg/day; however, the drug was stopped after 8 months because it did not produce viral clearance or return serum aminotransferase levels to within normal limits. The patient was not a candidate for interferon alfa therapy but was prescribed adefovir dipivoxyl 10 mg/day. Five months later, serum aminotransferase levels had normalized and, after 7 months of treatment with adefovir, the patient became negative for serum HBV-DNA and immunoglobulin M (IgM) antidelta. At the time of writing (20 mo of therapy), the HBV-DNA and IgM antidelta remained negative, whereas hepatitis B surface antigen and circulating HDV-RNA were positive. No adverse effects associated with adefovir were reported, and the Child–Pugh score (A6) had improved. Discussion: This is the first reported case of some beneficial biochemical and serologic effects of adefovir dipivoxyl in the treatment of delta cirrhosis. The virologic pattern of the patient after adefovir is indicative of poor liver disease activity and prospectively enhances liver transplantation outcome, indicating that adefovir might also be useful in the phase prior to liver transplantation. Conclusions: Although we have no plausible explanation for our patient's favorable response to adefovir treatment, this case contributes to the knowledge regarding treatment of this very difficult condition as well as adefovir efficacy. Given the positive outcome, this report suggests that adefovir might be beneficial in patients with delta-related liver cirrhosis not responsive to previous lamivudine therapy. Based on the high tolerability of this therapy, this case encourages clinical trials.

Abstract
Hepatitis D virus (HDV) or delta hepatitis has mainly been studied in Asian and Mediterranean cohorts, but data on virological and clinical characteristics of HDV-infected Central and Northern European patients are limited. We investigated virological patterns, as well as biochemical and clinical features of liver disease in 258 HDV infected patients recruited over a period of 15 years at Hannover Medical School. Virological parameters were compared to 2083 anti-HDV negative hepatitis B surface antigen (HBsAg) positive individuals. In this cohort, (i) HDV infection was associated with both suppressed hepatitis B virus (HBV) and hepatitis C virus (HCV) replication, (ii) the suppression of HBV-DNA and HCV-RNA was not related to HDV-RNA replication, (iii) mean HBsAg levels did not significantly differ between HBV-monoinfected patients and individuals with delta hepatitis, (iv) HCV coinfection was rather frequent as about one third of our delta hepatitis patients tested anti-HCV positive, however, without being associated with more advanced liver disease, (v) delta hepatitis patients presented in a high frequency with an advanced stage of liver disease, and (vi) the course of delta hepatitis did not differ between Turkish-born, Eastern European (EE)-born and German-born patients. In summary, in this cohort of patients which is the largest so far Central European single centre group of delta hepatitis patients, we confirm the presence of frequently severe disease and describe novel virological profiles which require consideration in the management of this difficult to treat group of patients.

Abstract
Death related to acute hepatitis B occurs in approximately 1% of patients. We investigated an outbreak of hepatitis B virus (HBV) infections among injection drug users (IDUs) resulting in several deaths. We conducted a case-control study of fulminant (case patients) and nonfulminant (control patients) HBV infections. We directly sequenced the entire HBV genome from fulminant and nonfulminant cases. From October 1998 to July 2000, 21 acute HBV infections, including 10 fulminant hepatitis B cases, were identified. The median age was 30 (range, 18-49) years, 12 (57%) were female, 20 (95%) were American Indians, and 20 (95%) reported injecting illicit drugs. All patients with fulminant hepatitis B died (case-fatality rate = 47.6%). Case patients (n = 5) and control patients (n = 9) were similar with respect to age, sex, race, and hepatitis C virus serostatus. All case patients used acetaminophen during their illness compared with 44% of control patients (P =.08). Compared with control patients, case patients lost more weight in the 6 months before illness (P =.04); during their illness, they used more alcohol (P =.03) and methamphetamine (P =.04). All 9 isolates sequenced were genotype D, shared 99.7% homology, and included mutations previously described in association with fulminant hepatitis B. In conclusion, a high prevalence of exposure to factors potentiating hepatic damage with acute hepatitis B contributed to the outbreak's high mortality rate; mutations present in the outbreak strain might also have been a factor. Improved vaccination coverage among IDUs has the potential to prevent similar outbreaks in the future.

Abstract
INTRODUCTION With the introduction of HAART, the HIV-1 has turned from a lethal into a chronic infection in the majority of patients. In homosexual populations, 20% of HIV-1 infected patients suffer from a chronic HBV infection, which may eventually lead to complications of the liver disease because of prolonged survival. Lamivudine is effective in reducing both HIV-1 and HBV viral replication. However, resistance for lamivudine may complicate the course of the HBV disease in HIV-1-infected patients. We, therefore, conducted a retrospective study in HIV-1-HBV co-infected patients on lamivudine therapy. PATIENTS AND METHODS All HIV-1-HBV co-infected patients who were treated with lamivudine for over 6 months in five major referral clinics in The Netherlands with HBV DNA above 2.0 x 10(5) geq ml(-1) at baseline, were evaluated. Retrospectively, the course of HBV DNA in available serum samples was established. If HBV DNA was detectable with the sensitive PCR-assay, YMDD-analyses of the polymerase gene of the hepatitis B virus was executed with the INNO-LiPA-DR-strip. RESULTS Forty-six patients were evaluated. The median level of HBV DNA at start of lamivudine therapy was 1.31 x 10(9) geq ml(-1) (range 3.5 x 10(5) - 2.0 x 10(10), n=43). Of three patients no baseline sample was available, but since HBV DNA was still above 2.0 x 10(5) geq ml(-1) at week 3, 7 and 11, these patients were included. Median duration of lamivudine therapy was 97 weeks (range 27-263). The percentage of detected mutations was 25 and 52% at 1 and 2 years, respectively. Twenty-two patients ultimately developed a mutation. Both baseline Body Mass Index (BMI) and the decrease in CD4 cell count as a time dependent factor were significantly related to the emergence of mutations. In 10 out of 12 evaluated patients, HBV DNA levels returned to baseline level or even above baseline level after the development of mutant virus. One patient (5%) developed a flare of serum transaminases (ALT>10 x ULN) 24 weeks after first detection of variant virus. CONCLUSION There is a linear time-dependent appearance of HBV mutations for lamivudine in our population. In a minority of patients (5%), development of a mutation was followed by a significant elevation of serum transaminases. A decline in CD4 cell count, which may indicate less response to HAART, induces a faster emergence of mutations and close surveillance of HBV co-infected patients on therapy may be indicated due to the prolonged survival of HIV-1 patients.

Abstract
Currently, the best option for patients with hepatitis delta is interferon alpha therapy for at least one year. To evaluate the effect of the combination lamivudine-high-dose interferon alpha therapy, we first treated eight patients with chronic hepatitis delta infection with lamivudine for at least 24 weeks; then lamivudine was combined with a high dose of interferon alpha followed by a regular dose (9 MU tiw). Follow-up was 12 weeks. Virological, biochemical and histological features were evaluated for response to therapy. At baseline, all patients were HBsAg positive in serum and HDV RNA-(PCR)positive in plasma; HBV DNA was undetectable with the Digene Hybrid Capture assay (limit of detection 1.5 x 10(6) geq ml-(1)) in all cases. Transaminases were elevated in all patients; median ALT 68 (range 48-143) IU l(1). Seven of eight patients completed the course; one patient with a pre-existing sickle cell trait was withdrawn from the trial due to the development of a nephrotic syndrome. The HBsAg-concentration in serum decreased in two out of seven patients (29%). However, there was no significant decrease in the HBsAg-concentration in serum during treatment (median 3654 PEU l(-1) (range 548-7,684) to 5300 PEU l(-1) (range 168-19,639)). The drop of HDV RNA in plasma from baseline during treatment was not significant. Decrease of HDV RNA was observed in three out of seven patients (43%) (median 10(5) geq ml(-1); range 10(3)-10(6) to median 10(3) geq ml(-1); range 10(2)-10(7)). Serum ALT did not change as reflected by a median of 68 IU l(-1) (range 48-143) at start of therapy to 63 IU l(-1) (range 20-171) at the end of therapy. At the end of treatment transaminases had normalised in one patient and decreased in three other patients (improvement in 57%). However, three of these four patients showed a rebound after withdrawal of therapy. The Histology Activity Index (HAI) indicated a drop from a median score of 7 (range 5-9) at baseline to 5 (range 3-8) at the end of treatment, but an increase in fibrosis from a median grade of 2 (range 1-3) at baseline to 3 (range 1-4) at the end of treatment was observed. In conclusion, this study does not yield support for the combination of an HBV suppressor and 16 weeks of high-dose interferon for therapy aimed at eradicating the hepatitis delta virus.

Abstract
BACKGROUND The effect of hepatitis delta virus (HDV) infection on the clinical course of cirrhosis type B is poorly defined. AIMS To investigate the impact of HDV status on morbidity and mortality in cirrhosis type B. PATIENTS/METHODS Retrospective cohort study of 200 Western European patients with compensated cirrhosis type B followed for a median period of 6.6 years. RESULTS At diagnosis, 20% of patients had antibodies to HDV (anti-HDV); median age was lower in anti-HDV positive cirrhotics (34 v 48 years respectively). Kaplan-Meier five year probability of hepatocellular carcinoma (HCC) was 6, 10, and 9% in anti-HDV positive/HBeAg negative, anti-HDV negative/HBeAg negative, and anti-HDV negative/HBeAg positive cirrhotics respectively; the corresponding figures for decompensation were 22, 16, and 19% and for survival they were 92, 89, and 83% respectively. Cox regression analysis identified age, albumin concentration, gamma-globulin concentration, and HDV status as significant independent prognostic variables. After adjustment for clinical and serological differences at baseline, the risk (95% confidence interval) for HCC, decompensation, and mortality was increased by a factor of 3.2 (1.0 to 10), 2.2 (0.8 to 5.7), and 2.0 (0.7 to 5.7) respectively in anti-HDV positive relative to HDV negative cirrhotic patients. The adjusted estimated five year risk for HCC was 13, 4, and 2% for anti-HDV positive/HBeAg negative, anti-HDV negative/HBeAg negative, and anti-HDV negative/HBeAg positive cirrhotics respectively; the corresponding figures for decompensation were 18, 8, and 14% and for survival 90, 95, and 93% respectively. CONCLUSIONS HDV infection increases the risk for HCC threefold and for mortality twofold in patients with cirrhosis type B.

Abstract
The causative agent of hepatitis delta virus (HDV) is the most unusual of all causative agents for all hepatitis viruses. Current knowledge of the molecular biology of HDV strengthens its proposed classification within the satellites, a family of subviral agents, some of which are pathogens of higher plants. Hepatitis delta virus is the only virus in the satellite family known to infect animal species, with hepatitis D having affected more than 10 million people worldwide who are also infected with its helper virus, HBV. Recently, the world map for hepatitis D appears somewhat modified, with decreasing HDV prevalence in certain areas and some new foci of HDV endemicity. Despite changing HDV prevalence, hepatitis. D, particularly the chronic form, is still an important health problem worldwide in terms of morbidity and mortality (mainly due to chronic liver disease, including hepatocellular carcinoma). Molecular studies have greatly advanced our understanding of the life cycle of HDV and of the function of its proteins. The new molecular information is of clinical relevance, with implications for the pathogenesis of liver damage, the diagnosis of HDV infection, for the natural course of the disease and, potentially, for therapy. Sensitive assays for HDV-RNA by polymerase chain reaction and sequencing techniques have clarified the patterns of HDV transmission and have confirmed the existence of unusual clinical forms of the virus and their relationship to replicative levels and genotypes of HDV. Prevention and treatment of hepatitis D are still in their infancy. However, liver transplantation for delta cirrhosis has proven far more successful than in any other viral form of cirrhosis, with few reinfections of the grafted liver, and has given important information on HDV biology and the pathogenesis of liver damage.
