Abstract
INTRODUCTION Evaluation of cirrhosis appears to be easily overlooked in the clinic for the HBsAg-negative (hepatitis B surface antigen-negative) and HBcAb-positive (hepatitis B core antibody-positive) population. Herein, we determine the prevalence of cirrhosis/advanced fibrosis among HBsAg-negative/HBcAb-positive US adults. METHODS Data came from the National Health and Nutrition Examination Survey (NHANES) 2001-2018. A total of 3115 HBsAg-negative/HBcAb-positive US adults were enrolled in this study. We assessed cirrhosis by using the Fibrosis-4 (FIB-4) and aspartate aminotransferase to platelet ratio index (APRI) score. RESULTS Out of 50,201 NHANES adults, 45,087 were tested for HBcAb/HBsAg, of whom 3115 met the inclusion criteria (HBsAg-negative/HBcAb-positive with available data for FIB-4/APRI). The weighted proportion of HBsAg-negative/HBcAb-positive among US adults was 4.46% (95% CI 4.17-4.75%), affecting 9.87 million US adults. According to the results of the FIB-4, the weighted prevalence of cirrhosis/advanced fibrosis among HBsAg-negative/HBcAb-positive US adults was 3.76% (95% CI 2.80-4.72%), which corresponds to 371,112 (95% CI 276,360-465,864) HBsAg-negative/HBcAb-positive American adults who had already developed cirrhosis. Among those, cirrhosis/advanced fibrosis in the HBsAb-negative (hepatitis B surface antibody) group (6.28%, 95% CI 4.10-8.45%) was significantly higher than in the HBsAb-positive group (3.08%, 95% CI 2.07-4.08%). Results were similar when APRI was used. CONCLUSION According to the FIB-4, 3.76% of HBsAg-negative and HBcAb-positive US adults had cirrhosis/advanced fibrosis, much higher than in the general population of the USA. Our data highlight the importance of cirrhosis screening in the HBsAg-negative/HBcAb-positive population to prevent advanced liver disease, especially in those who are HBsAb-negative.

Abstract
BACKGROUND AND AIM The aim of the present study was to investigate whether spontaneous seroclearance of hepatitis B surface antigen (HBsAg) in patients with chronic hepatitis B could be attributed to the presence of pre-S/S gene mutations. METHODS Of 34 hepatitis B virus (HBV) carriers who experienced spontaneous seroclearance of HBsAg, 30 were still seropositive for HBV DNA. The serum samples of these carriers were subjected to sequence analysis. RESULTS A novel pre-S2 mutation, G149R, was found in nine (group I) but not in 17 (group II) patients carrying HBV DNA with intact pre-S/S reading frames. In the remaining four patients (group III), only aberrant pre-S/S transcripts were found in their sera. Distinct patterns of amino acid substitutions specific to group I and II patients were identified. Superinfection by hepatitis C or D virus occurred predominantly in group II patients (P = 0.019). Superinfection by HBV of a different genotype occurred predominantly in patients without hepatitis C or D virus superinfection (P = 0.013). Site-directed mutagenesis experiments showed that secretion of HBsAg was not defective in the pre-S2 G149R mutant. CONCLUSIONS In a particular subgroup (group I) of patients, seroclearance of HBsAg was not caused by superinfection of other hepatitis viruses, nor was it caused by failure of HBsAg secretion or detection. Instead, a yet unrecognized mechanism associated with emergence of a novel pre-S2 mutation is responsible.

Abstract
The incidence of cryptogenic cirrhosis (CC) has decreased since the discovery of hepatitis C virus (HCV), still the etiology in 5% of cases with cirrhosis remains unresolved. Our aims were to define the clinicopathologic features of CC at liver transplantation (LT), evaluate the post-LT course with outcome and define the possible pathogenetic mechanisms. 27/534 LT recipients (5%) over a period of 16.5 years were entered in the LT database as cases of CC. A detailed analysis of pre- and post-LT clinical and all liver pathology specimens was performed. Based on clinicopathologic findings, a more definite diagnosis was possible in 23 of 27 (85%): Nonalcoholic steatohepatitis (NASH) in 9 (33%), autoimmune liver disease (AILD) in 6 (22%), alcoholic liver disease in 4, secondary biliary cirrhosis in 2 and 1 each of hepatitis C and portal venopathy. 4/27 cases remained unresolved. In the NASH group, native livers had focal steatosis, Mallory's hyalin, glycogenated hepatocytic nuclei, high-grade inflammation, and 3+ bile duct proliferation. Large cell dysplasia was more common in this group compared to other patients. Two patients had recurrence of NASH after LT. In AILD group native livers had little or no bile duct proliferation. Two patients had recurrence in AILD group. Of 27 patients 19 are alive (70%) with a follow-up of 407-3647 days. Based on the study results, the following conclusions were reached: (1) CC results from varying etiologies, which can be defined by a careful clinicopathologic analysis in a majority (85%) of cases; (2) Nonalcoholic steatohepatitis (33%) and AILD (22%) are the common underlying causes of CC; and (3) Post-LT outcome for CC is disease dependent with, recurrent disease seen in both nonalcoholic steatohepatitis (22%) and autoimmune liver disease (33%).

Abstract
The incidence of delayed hepatitis B surface antigen (HBsAg) clearance in the natural history of chronic hepatitis B virus (HBV)-infected patients was low. Previous studies regarding the prognosis in such patients were controversial. Among 1,355 chronic carriers from 1985 to 1997, spontaneous HBsAg clearance was observed in 55 patients. During a mean follow-up period of 23 months, 18 (32.7%; all were male subjects) developed serious complications, including 11 with hepatocellular carcinoma (HCC) (9 of them underwent surgical resection), 6 with cirrhosis, and 1 with subfulminant liver failure. The overall cumulative probability of complications was 29.8% at 4 years, and it was higher in males (P = .044) and patients aged 45 years or more (P = .006); the latter carried an 8.6-fold increased risk (95% CI: 1.2-64.6; P = .037) of adverse events. Histories of acute or chronic infection by hepatitis A virus, C virus (HCV), or D virus (HDV) were present in 42% of patients. Patients seropositive for antibodies against HCV (anti-HCV) or HDV (anti-HDV) had higher alanine transaminase (ALT) levels (>40 U/L; P = .008) after sero-clearance. HBV DNA was detectable in 31% of 51 subjects, in 20% of 20 with antibodies against HBsAg, in 40% of 20 with anti-HCV or anti-HDV, and also in an HCC patient's serum and tumor. Staining of liver HBsAg was positive in 30% of 10 HCC patients. In conclusion, our results demonstrated that hepatitis B viremia may persist, and adverse complications were not rare in HBsAg-clearance patients. All such patients should be closely monitored, which may allow for earlier detection of HCC.

Abstract
OBJECTIVE The aim of this study was to evaluate the incidence, prognostic factors and clinical significance of delayed clearance of serum HBsAg in compensated cirrhosis B. METHODS This was a retrospective cohort study of 309 consecutive white patients with biopsy-proved compensated cirrhosis type B. RESULTS During a mean follow-up of 68 months, HBsAg loss occurred in 32 patients, including 16 (8%) of 196 untreated patients (mean annual incidence 0.8%), 8 (10%) of 82 interferon (IFN) alpha-treated patients and eight patients who had been treated with other antivirals or steroids. The 5-yr probability of HBsAg loss was 4% and 16% for untreated and IFN-treated patients, respectively (p = 0.0001). Cox's regression analysis identified hepatitis B e antigen-positivity at entry as the sole independent prognostic factor for HBsAg loss. Of the 32 patients who lost HBsAg, one (3%) subsequently developed hepatocellular carcinoma (HCC) and died, whereas, among the patients who remained HBsAg-positive, 11% developed HCC and 20% had died. The probability of HCC appearance was lower (p = 0.0137) and survival was longer (p = 0.0006) in patients who cleared HBsAg compared with patients with HBsAg persistence. CONCLUSION The incidence of HBsAg loss is about 0.8% in cirrhosis type B. Prognostic factors for clearance of HBsAg are initial HBeAg positivity and therapy with alpha interferon. Patients with cirrhosis type B, who lose HBsAg, have a low risk for liver cancer or liver-related death.

Abstract
We investigated the frequency of HBsAg clearance and the possible role of viral superinfection in a long-term follow-up of 184 patients with chronic hepatitis B (CHB). Our subjects were 184 patients with chronic hepatitis B and the follow-up was 12-216 months (mean 66.2 +/- 53.7 months). The investigative methods used were: immunoenzymatic assays for HBV, HCV, HDV, and HIV markers; polymerase chain reaction (PCR) for HBV DNA; and liver biopsy and immunoperoxidase. During the follow-up, 20 of the 184 patients cleared serum HBsAg. A comparison of patients with persistent HBsAg(group I) and of those who cleared this marker (group II) showed a significant difference in mortality (P = 0.002) between the two groups and a tendency to a more severe exacerbation (flare) in group II (P = 0.07). Antibodies to hepatitis C and D virus as well as antibodies to HIV were equally distributed in both groups. Thirteen patients (7.9%) from group I, but none from group II, subsequently developed hepatocellular carcinoma. These results suggest that the frequency of spontaneous clearance of HBsAg during chronic HBV infection is low. No determinant factor for the clearance was found, including the presence of liver cirrhosis. Serum HBV DNA was undetectable by PCR after clearance in 16 out of 17 patients.

Abstract
Viral hepatitis has become a difficult field in which clinical and laboratory skills are needed to establish the correct diagnosis and plan for the appropriate therapy. For example, it is no longer enough to diagnose chronic hepatitis B or C. Now, the viral titer or viral genotype must be known. The laboratory test then must be understood in the context of the clinical presentation. This article helps the clinician to acquire such working knowledge. It summarizes available data for hepatitis A, B, C, D, and E. It also includes the recently discovered viral agents, hepatitis G and the hepatitis GB agents.

Abstract
The natural history of chronic hepatitis B patients who spontaneously cleared serum HBsAg was investigated. A total of 351 patients with chronic hepatitis B were observed in our hospital for at least 3 yr. Seven of these patients became HBsAg negative during the follow-up period. HBsAg disappeared within 6 mo (range = 11 to 169 days, mean = 70 days) after acute elevation of ALT. ALT levels as high as 500 IU were found in three patients, whereas such elevation was not demonstrated in the other four patients. After the disappearance of HBsAg, ALT levels returned to normal in all patients. With one exception, all patients seroconverted to antibody to HBsAg; however, hepatitis B virus DNA remained detectable in serum using the polymerase chain reaction in five patients. The titer of percent inhibition of antibody to HBcAg gradually decreased to less than 70% when a 1:200 dilution of the serum of six patients was used. Four of the patients had active liver disease develop: two had chronic active hepatitis and two had cirrhosis. Three of these four patients subsequently had hepatocellular carcinoma develop. These findings suggest that patients may suffer complications of chronic hepatitis even after normalization of transaminase activities and after the clearance of HBsAg. Thus hepatitis B virus should be considered as a possible factor associated with hepatocellular carcinoma even in the absence of HBsAg, particularly if serum hepatitis B virus DNA persists.

Abstract
To investigate the incidence, determinants and significance of delayed clearance of serum HBsAg in chronic hepatitis B virus infection, a prospective follow-up study was conducted in two consecutive groups of patients. Group I consisted of 984 patients (859 men and 125 women) with biopsy-proven chronic type B hepatitis, whereas group II consisted of 1,598 asymptomatic chronic carriers (998 men and 600 women) with normal serum aminotransferase activity. During a mean follow-up period of 4.0 +/- 2.3 yr, 19 patients (1.9%) of group I cleared HBsAg from their serum, whereas 35 patients (2.2%) in group II did so in a mean follow-up period of 2.7 +/- 1.4 yr. The annual incidence of delayed serum HBsAg clearance was 0.5% in group I and 0.8% in group II (p less than 0.02). The cumulative probability of HBsAg clearance was also higher in group II than in group I (p less than 0.007). Antibodies to HBsAg developed in 9 patients (47.4%) with chronic hepatitis and in 11 (31.4%) asymptomatic carriers who cleared serum HBsAg. Those who were HBeAg negative and those older than 40 at entry and those who exhibited cirrhosis during follow-up had a higher incidence of delayed HBsAg clearance. Gender, initial histological changes and hepatitis delta virus infection did not influence the occurrence of HBsAg clearance. Serum HBV DNA was not detectable by slot-blot hybridization but was still detectable by polymerase chain reaction in serum specimens collected within 1 yr of HBsAg clearance. Liver biopsy performed later in 10 patients showed no significant hepatitis activity or tissue HBV DNA, HBsAg or HBcAg.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A total of 20 patients with histologically proven primary hepatocellular carcinoma (PHC) received mitoxantrone IV at a dose of 10-16 mg/m2 every 3 weeks. All patients had previous hepatitis B infection. None underwent remission after treatment; 2 had stable disease and 18 progressive disease. The median overall survival was 13 weeks (range, 1-59 weeks). There was no evidence of significant antitumor activity for mitoxantrone in our patients with PHC. Hematotoxicity occurred in 100% of the patients with grades 2-4 leukopenia, 89% of those with grades 1-4 anemia, and 26% of those with grades 2-3 thrombocytopenia. Cardiotoxicity occurred in 20% of the patients after 14-30 mg/m2 mitoxantrone; these included complete heart block with fatal outcome in one case, decreased ventricular ejection fraction in one, and sinus tachycardia in two. Nausea, vomiting, fever, diarrhea, and alopecia were mild and occurred in 15%-45% of the patients Therefore, patients with PHC following hepatitis B infection may be less tolerant to mitoxantrone, resulting in the apparent increase in toxicities.
