Are current screening protocols for chronic hepatitis B virus infection adequate? Diagn Microbiol Infect Dis 2015; 85:159-67. [PMID: 27009896 DOI: 10.1016/j.diagmicrobio.2015.12.005] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2014] [Revised: 11/30/2015] [Accepted: 12/14/2015] [Indexed: 12/15/2022]
Abstract
Chronic hepatitis B virus (HBV) infection screening usually includes only HBV surface antigen (HBsAg) testing; HBV core and surface antibody (anti-HBc, anti-HBs) assays, indicating resolved infection and immunity, are not routinely performed. Yet, serum HBV DNA is measurable in approximately 10% of HBsAg-negative/anti-HBc-positive cases, representing occult HBV infection (OBI). Patient blood samples from 2 Veterans Affairs medical center look-back investigations were screened for HBV infection using HBsAg enzyme immunoassays. Supplementary testing included anti-HBc and anti-HBs enzyme immunoassays. For anti-HBc-positive samples, HBV DNA testing was performed. Background OBI prevalence was further estimated at these 2 facilities based on HBV serology testing results from 1999-2012. Finally, a literature review was performed to determine OBI prevalence in the published literature. Of 1887 HBsAg-negative cohort patients, 98 (5.2%) were anti-HBc positive/anti-HBs negative; and 175 (9.3%), anti-HBc positive/anti-HBs positive. Six of 273 were HBV DNA positive, representing 0.3% of the total tested and 2.2% who were anti-HBc positive/anti-HBs negative or anti-HBc positive/anti-HBs positive. Among 32,229 general population veterans at these 2 sites who had any HBV testing, 4/108 (3.7%) were HBV DNA positive, none of whom were part of the cohort. In 129 publications with HBsAg-negative patients, 1817/1,209,426 (0.15%) had OBI. However, excluding blood bank studies with greater than 1000 patients, the OBI rate increased to 1800/17,893 (10%). OBI is not rare and has implications for transmission and disease detection. HBsAg testing alone is insufficient for detecting all chronic HBV infections. These findings may impact blood donation, patient HBV screening, follow-up protocols for patients assumed to have cleared the infection, and initiation of immunosuppression in patients with distant or undetected HBV.

Abstract
The presence of hepatitis C virus (HCV) RNA in serum and liver tissue was examined in seven patients with hepatocellular carcinoma (HCC), using the reverse transcriptase-polymerase chain reaction method with primers for the 5'-noncoding region. Plus-strand HCV-RNA was detected in the serum and liver tissue (both cancerous and noncancerous tissue) of all five patients who were positive for anti-HCV antibodies (C100-3 and P22) and was not detected in both of two patients who were negative for anti-HCV antibodies. Minus-strand HCV-RNA was only detected in the liver tissue (cancerous and noncancerous portion) of the five anti-HCV antibody-positive patients. The relative liver tissue content of minus-strand HCV-RNA ranged from 1 to 100 time less than that of plus strand HCV-RNA in cancerous and noncancerous tissue in each patient, respectively. There was no similar tendency in the HCV-RNA content between the cancerous and noncancerous portions of the liver in each patient. These results suggest that HCV exists and replicates in HCC tissue and may have some role in the development of HCC.

Abstract
Serum hepatitis B virus (HBV) infection markers were studied in 272 patients with homozygous genetic haemochromatosis complicated (n = 33) or not (n = 239) with primary liver cancer (PLC). Controls consisted of 255 029 healthy blood donors from whom age- and sex-matched control groups were extracted for statistical evaluation using the Fisher exact test. In blood donors, HBsAg was positive in 0.075% of males and 0.04% of females. This population was not screened for anti-Hbs. Anti-Hbc alone (without HBsAg) was present in 3.7% of men and 1.8% of women. In patients with genetic haemochromatosis without liver cancer (183 males, 45.6 +/- 11.3 yrs and 56 women, 48 +/- 12.4 yrs), HBsAg was found in 1.1% of men and in none of the women. Anti-HBs was present in 7.3% of males and 1.8% of females. Anti-HBc alone was found in 13% of males (p less than 0.005 vs. controls) and 2.1% of females. From male patients with primary liver cancer complicating genetic haemochromatosis (32 males, 61.7 +/- 6.8 yrs and one female), 6.2% were HBsAg positive, 3.4% were anti-HBs positive and 16.6% anti-HBc positive (p = 0.05 vs. controls). No serum HBV marker was found in the woman. In conclusion, the prevalence of HBV infection markers--especially anti-HBc--is significantly increased in patients with genetic haemochromatosis complicated or not with primary liver cancer.

Abstract
Patients with overt alcoholic liver disease who had participated in a multicenter therapeutic trial and subgroups of controls (i.e., alcoholic patients without liver disease and patients with neither alcoholism nor liver disease) were tested for hepatitis B virus and hepatitis C virus antibodies to determine the prevalence of these antibodies to determine the prevalence of these antibodies and any clinical association in the progression and outcome of alcoholic liver disease. Antibodies to hepatitis B (anti-HBs and/or anti-HBc) were found in 29.2% of patients with alcoholic liver disease, in 26.1% of hospitalized alcoholic patients without liver disease and in 24.2% of hospitalized nonalcoholic patients without liver disease; frequencies were not significantly different from one another. HBsAg was not evaluated because HBsAg+ patients had been excluded from the original trial. The presence of these antibody markers correlated with ethnic origin of and immunoglobulin levels in the patients. In contrast, antibody to hepatitis C, as detected by enzyme immunoassay, was positive in 27.1%, 4.8% and 3.0% of the three groups, respectively, the first differing significantly from the other two. Antibody to hepatitis C virus positivity correlated significantly with clinical severity of the disease and with the presence of histological features that imply chronic viral infection (periportal inflammation, cirrhosis), despite the fact that the supplementary assay for antibody to hepatitis C virus, using recombinant immunoblot assay, reduced the positive rate by 79%.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In a retrospective study clinical features of hepatocellular carcinoma (HCC) in the Amsterdam area (1984-89) were assessed in 61 cases. The data obtained were used to discuss some of the current concepts on aetiology, diagnosis, and treatment of HCC. Presenting symptoms and findings usually reflected advanced (incurable) disease. Of the patients 25% had a normal alpha-1-foetoprotein (AFP), 55% had elevated levels, and in 20% data were absent. Platelet counts greater than 500 x 10(9)/l were found in 8% and hypercalcaemia in 10% of the patients. Treatment modalities were none (70%), surgery (16%), chemotherapy (8%), radiotherapy (3%), and endoprosthesis (2%). Sixty to 70% had died after 3 months and more than 90% after 1 year. Long survivors included 2 patients with the fibrolamellar type of HCC. The low incidence of HCC in The Netherlands probably precludes cost-effective screening programs to identify resectable small HCC. Unidentified masses are malignant until proven otherwise and should be resected if no firm diagnosis of benign disease can be made. Awareness of HCC and its risk factors may lead to earlier diagnosis and more selective use of diagnostic tests.
