Abstract
Vitamin D exhibits immunomodulatory and antiproliferative effects through vitamin D receptor (VDR) in chronic infections and cancers. We genotyped the BsmI (rs1544410), ApaI (rs7975232) and TaqI (rs731236) polymorphisms of VDR gene in 250 Taiwanese chronic hepatitis B virus (HBV) carriers who were categorized into six phenotypes. After adjustment for age and sex, the frequencies of the VDR B/b, B/a, B/T, B/a/T in patients with hepatitis flare(s) were lower than those without (7 vs 20%, P=0.009; 1 vs 9%, P=0.004; 3 vs 10%, P=0.007; 1 vs 9%, P=0.005, respectively); in contrast, T/t, A/T, A/t, b/A/t were higher in flare(s) (8 vs 3%, P=0.003; 49 vs 34%, P=0.027; 2 vs 1%, P=0.004; 0.5 vs 0%, P=0.001, respectively). In addition, B/b, B/B, T/t, b/A, B/a, B/A, B/T, B/t, A/t, b/A/T, B/a/T, B/A/T, B/A/t, b/A/t were higher in patients positive for HBeAg. The distribution of VDR genotypes was comparable between patients with and without hepatocellular carcinoma (HCC). VDR gene polymorphisms are associated with distinct clinical phenotypes in Taiwanese HBV carriers but not with HCC development.

Abstract
Human leukocyte antigen (HLA) class II molecules are associated with host immune responses against hepatitis B virus infection. Male gender is the apparent host factor when someone encounters with the severity of hepatitis. The aim of this study was to investigate the association of the most polymorphic HLA class II allele, human leukocyte antigen-DRB1, with the severity of hepatitis in male carriers of hepatitis B virus. In this prospective cohort study, a total of 204 carriers of hepatitis B virus (131 men and 73 women) who have been followed-up for more than 1 year at the outpatient clinic of a university hospital were collected consecutively. Fifty carriers of hepatitis B virus (group I) with alanine aminotransferase <2x upper limit of normal (mean follow-up 83.6 months) were compared with 154 chronic hepatitis B patients (group II) with alanine aminotransferase >/=2x upper limit of normal (mean follow-up 81.3 months). Alleles of HLA-DRB1 were typed by the polymerase chain reaction-sequence specific oligonucleotide probe hybridization and genotypes of hepatitis B virus by melting curve analysis. HLA-DRB1*1101 was found in 18% of group I versus 8% of group II in male carriers (OR 0.23, P = 0.020, after adjustment for age) and 4% versus 9.4% in female carriers (P = 0.094). In male carriers harboring DRB1*1101, the distribution of hepatitis B viral genotype was comparable between the two groups. HLA-DRB1*1101 correlates with less severe hepatitis in Taiwanese male carriers of hepatitis B virus.

Abstract
The HLA DR13 allele has been associated with a self-limited course of hepatitis B virus infection, possibly through the induction of a more vigorous hepatitis B core antigen (HBcAg) and/or hepatitis B e antigen-specific CD4(+) T cell response. HBcAg-specific CD4(+) T cell responses were investigated in three HLA DR13-positive subjects with self-limited, acute hepatitis B. HBcAg-specific, short-term T cell lines derived from these three subjects showed a dominant recognition of HBcAg peptides spanning aa 1-20 (P1), 11-30 (P2), 41-60 (P5), 111-131 (P12) and 141-160 (P15). In order to characterize these epitopes in more detail, CD4(+) T cell clones and cell lines were generated using HBcAg. Surprisingly, 11 of 12 T cell clones examined recognized P15; one recognized P10 (aa 91-111). Of four T cell lines, two recognized P15 and two recognized P5. By peptide mapping, the minimal epitope of P15 was located to residues (147)TVVRRRGRSP(156).

Abstract
OBJECTIVE Circumstances predisposing hepatitis C virus (HCV)-infected patients to develop mixed cryoglobulinemia (MC), which may manifest as a small-vessel systemic vasculitis (MC vasculitis), remain unclear. Previous studies have failed to demonstrate a clear role of either viral factors (genotype, viral load) or host factors (lymphocytes or immunoglobulin subsets). This study was undertaken to examine a possible role of HLA class II alleles in HCV-associated MC. METHODS One hundred fifty-eight HCV-infected patients, of whom 76 had MC (56 with type II MC and 20 with type III MC) and 82 did not have MC, were studied prospectively. MC vasculitis was noted in 35 HCV-infected patients with type II IgMkappa-containing cryoglobulins. HLA-DRB1 and HLA-DQB1 polymorphism was analyzed by hybridization using allele-specific oligonucleotides, after gene amplification. The odds ratio (OR) was calculated with Woolf's method. Then, using multivariate analysis, demographic, biologic, immunologic, virologic, and liver histologic factors associated with the presence of MC and MC vasculitis were investigated. RESULTS HLA-DR11 was significantly more frequent in patients with type II MC than in those without MC (41.1% versus 17.1%; OR 3.4, corrected P [Pcorr] = 0.017), regardless of the presence of vasculitis accompanying the MC (37.1% of those with MC vasculitis, 34.1% of those with MC but no vasculitis). HLA-DR7 was less frequent in HCV-infected patients with MC than in those without MC (13.2% versus 30.5%; OR 0.34, P = 0.012, Pcorr not significant), with a particularly lower frequency in those with type II MC and those with MC vasculitis (12.5% and 8.6%, respectively). There was no significant difference in HLA-DQB1 distribution between the different patient groups. By univariate and multivariate analysis, HLA-DR11 was the only positive predictive factor, besides female sex and advanced age, for the presence of MC and HCV-associated MC vasculitis (OR 2.58). CONCLUSION Our results indicate that the presence of the DR11 phenotype is associated with a significantly increased risk for the development of type II MC in patients with chronic HCV infection. In contrast, HLA-DR7 appears to protect against the production of type II MC. These results suggest that the host's immune response genes may play a role in the pathogenesis of HCV-associated MC.

Abstract
Major histocompatibility complex (MHC) determinants control antibody production in response to protein antigens. Vaccination with hepatitis B surface antigen (HBsAg) frequently fails in hemodialyzed patients, but the genetic factors that modulate humoral responsiveness are poorly characterized. We studied the distribution of HLA class II alleles in 415 hemodialyzed Caucasian patients who received a full course of HBsAg vaccination, using class II oligotyping after genomic amplification of the DRB1 and DQB1 loci. Phenotype frequencies were compared in 114 non responders (anti-HBs antibodies < or = 10 SI units/liter), 301 responders (anti-HBs antibodies > 10 units/liter) and 471 healthy controls. DRB1*01 (DR1) and DRB1*15 (DR15) frequencies were lower in nonresponders than in responders and controls (DR1, 12.3% vs. 22.9% and 24.8%, respectively; DR15, 14% vs. 22.9% and 25.1%), while DRB1*03 (DR3) and DRB1*14 (DR14) frequencies were higher (DR3, 32.5% vs. 16.6% and 25.3%, respectively; DR14, 9.6% vs. 3% and 6.6%). Overall, 44.5% of DR3 or DR14 patients were nonresponders, compared to 18.1% of DR1 or DR15 patients (P = 0.0001). In conclusion the humoral response to HBsAg vaccine is influenced by class II allelic variants, which differ in their capacity to bind and present peptides to T lymphocytes.

Abstract
Correlation between the major histocompatibility complex class I antigens (HLA-A, -B and -C) and the elimination from serum of hepatitis C virus in patients with chronic hepatitis C has not been understood. We analyzed HLA phenotypes and their relationship to the efficacy of interferon treatment. Of the 172 patients who were treated with 9 million units of interferon-alpha 2a three times a week for 6 months, 54 patients were responders and 118 patients were non-responders. No significant difference was observed between the 172 patients and 199 healthy subjects with regard to the frequencies of HLA-A, -B and -C antigen phenotypes. However, HLA-B55, B62, CW3 and CW4 frequencies were significantly higher in responders than in non-responders to the interferon treatment. CW4 was found to link with B62, but other phenotypes were independent each other. Patients with HLA B55, B62 and CW3 had a significantly lower viral load, and showed a better response to interferon. These results suggest that HLA system does not have an influence on the evolution towards chronicity of the disease due to hepatitis C virus, but HLA B55, B62 or CW4, and CW3 may be a virus quantity-regulating factors which then affect to response to the interferon treatment, indicating that these HLA antigens in conjunction with a viral peptide is a key target antigen for cytotoxic T lymphocytes in patients with chronic hepatitis C.

Abstract
BACKGROUND/AIMS The outcome of acute hepatitis B infection may be influenced by host factors like the major histocompatibility complex (MHC). We have investigated MHC class I and class II antigens in patients with chronic hepatitis B compared to a healthy control population. To confirm the findings of this first study we performed a second study in a group of subjects who had spontaneously recovered from acute hepatitis B infection. METHODS Frequencies of MHC class I and class II antigens were analyzed in patients with chronic hepatitis B virus infection and in control subjects. MHC class I typing was done by standard microlymphocytotoxicity assays. DRB1 and DQA1 genotypes were determined by polymerase chain reaction based typing methods. RESULTS In the first study the class II allele HLA-DRB1*1301-02 was found in 4 of 70 subjects with chronic hepatitis B virus infection (5.7%) compared to 27 of 101 healthy controls (26.7%, relative risk 0.17; p=0.001; p(corr)=0.025). This protective effect of the DRB1*1301-02 allele was confirmed in the second study. Eight of 24 patients (33.3%) who cleared hepatitis B virus spontaneously were positive for DRB1*1301-02 (relative risk of developing chronic infection compared to chronic hepatitis B subjects 0.12; p=0.004). Subtyping confirmed that 1301 and 1302 were both decreased in frequency in patients with chronic hepatitis B. CONCLUSIONS The MHC class II allele DRB1* 1301-02 is associated with protection from chronic hepatitis B in Caucasian patients.

Abstract
BACKGROUND Divergent results have been reported with regard to the relationship between the course of hepatitis B virus (HBV) infection and the human leukocyte antigen (HLA) determinants. The aim of the present study was to investigate the phenotype frequencies of HLA class-I and -II alleles in Caucasians with and without HBV infection. METHODS Fifty-eight patients with persistent HBV infection (group 1), 119 patients with resolved HBV infection (group 2), and 106 patients neither infected by HBV nor vaccinated against HBV (group 3) were analyzed. All patients had end-stage renal disease. HLA class-I antigens were serologically determined. For HLA class-II typing we performed DRB1, DQA1, and DQB1 genotyping using a polymerase chain reaction-sequence-specific oligonucleotide procedure. RESULTS Compared with group 2, group 1 showed increased frequencies of HLA-B8, DR3 (P < 0.05), A30, DQA1*0501 (P < 0.01), and a decreased frequency of HLA-B12 (P < 0.05). Decreased frequencies of HLA-B27, B40, DR13, and DQ1*0604 (P < 0.05) and an increased frequency of HLA-B35 (P < 0.05) were found in groups 1 and 2 compared with controls (group 3). None of the differences detected in the phenotype frequencies of HLA alleles were statistically significant after correction. CONCLUSIONS We conclude that the susceptibility to HBV infection and the different courses of HBV infection are not strongly related to HLA status in Caucasians.

Abstract
AIMS We aimed to test the hypothesis that susceptibility to chronic HBV, HDV and HCV infections or their pathology is influenced by host genetic factors. METHODS The Human Leukocyte Antigens (HLA) (A, B, DR and DQ) were determined by microlymphocytotoxicity assay in patients with chronic C (n = 117), B (n = 97) or D (n = 27) hepatitis and their frequencies were compared with those of 489 healthy controls. RESULTS No statistically significant association was found between any HLA antigen and chronic B or D hepatitis. A significantly higher frequency of HLA-B14 was observed in patients with chronic persistent or active C hepatitis (16.7% of 90 versus 5.9% of 489, chi(2) = 10.9, pc < 0.05, Relative Risk = 3.17, Etiological Fraction = 0.11). The frequency of HLA-DR5 was lower in HCV positive patients (24.8%) than in controls (45%, chi(2) = 15.1, pc < 0.005, RR = 0.4, EF = -0.37). CONCLUSIONS No correlation could be observed between clearance of HBV or HDV and HLA phenotype. Immunogenetic factors may have a role in determining susceptibility to chronic HCV hepatitis, and in Italian patients HLA-DR5 is a protective factor.

Abstract
BACKGROUND The course of hepatitis B virus (HBV) infection does not appear to be determined by variations in viral virulence and may be influenced by the host immune response. We studied the distribution of human leukocyte antigens in children and adult men in the Gambia who spontaneously recovered from HBV infection as compared with the distribution of these antigens in subjects with persistent infection. METHODS In a two-stage, case-control study, we analyzed the frequency of MHC class I antigens and class II haplotypes in people with either transient or persistent HBV infection. MHC class I typing was performed by microlymphocytotoxicity assays. MHC class II typing was performed with analysis of restriction-fragment-length polymorphisms (RFLPs), supplemented by other techniques. RESULTS In the first stage (the study of children up to the age of 10 years), the RFLP pattern 25-1, which includes the class II allele HLA-DRB1*1302, was found in 58 of 218 subjects with transient HBV infection (26.6 percent) and 30 of 185 subjects with persistent infection (16.2 percent) (relative risk of carrying the 25-1 pattern in the persistently infected group as compared with the transiently infected group, 0.53; 95 percent confidence interval, 0.32 to 0.90; P = 0.012). In the second stage (the study of adults), HLA-DRB1*1302 was found in 50 of 195 subjects with transient HBV infection (25.6 percent) and in 3 of 40 subjects with persistent infection (7.5 percent) (relative risk, 0.24; 95 percent confidence interval, 0.04 to 0.80; P = 0.012). The RFLP pattern 13-2, which includes the class II allele DRB1*1301, was less frequent in children with persistent infection than in those with transient infection, an association that was neither confirmed nor excluded by the data on adults. Possible associations with HLA class I antigens found in children were not supported by the data on adults. CONCLUSIONS The MHC class II allele DRB1*1302 was associated with protection against persistent HBV infection among both children and adults in the Gambia.

Abstract
The role of HLA antigens in the chronicity of viral hepatitis is still being debated. We analyzed the relation between HLA status and viral hepatitis in 558 consecutive haemodialyzed patients who underwent kidney transplantation. HLA A, B, DR status, ABO-Rh blood group, duration of haemodialysis, and number of blood units transfused during the dialysis period were known for all patients. Serological status for hepatitis B virus and hepatitis C virus and results of liver biopsies were available in 495, 300 and 316 patients, respectively. After correction for the number of tests performed, frequencies of HLA antigens did not differ significantly for: 1. hepatitis B virus infection (compared to HBsAg-positive and anti-HBc and/or anti-HBs-positive nonvaccinated patients); 2. hepatitis C virus infection (compared to anti-HCV-negative and -positive patients); 3. histopathological status (compared to patients who had chronic viral hepatitis and those who did not). These results suggest that there is no evidence for a significant role of a particular HLA antigen in the development of chronic viral hepatitis in haemodialysis patients with similar underlying immunosuppression and exposure to infection by hepatotropic viruses.

Abstract
To assess the frequency and genetic predispositions of concurrent immunological diseases and immunoserological markers in autoimmune hepatitis and chronic viral hepatitis, we assessed 185 patients prospectively, including 122 patients with autoimmune hepatitis and 63 patients with viral disease. Human leukocyte antigens were determined in all patients. Sixty patients (32%) had concurrent immunological diseases, and the majority of the diseases (68%) had known human leukocyte antigen associations. Although patients with autoimmune hepatitis had concurrent immunological diseases more commonly than those with viral disease (38% vs. 22%; p = 0.04), the nature of the diseases was similar in both groups, as were the frequencies of human leukocyte antigen-DR4 (42% vs. 39%; p = 0.7). The presence of human leukocyte antigen-DR4 was associated with the concurrence of immunological diseases in both autoimmune (62% vs. 33%; p = 0.01) and viral hepatitis (75% vs. 29%; p = 0.009). In autoimmune hepatitis, human leukocyte antigen-DR4 was also associated with the expression of smooth muscle antibodies and high-titer antinuclear antibodies. We conclude that concurrent immunological diseases and immunoserological markers are common in autoimmune and chronic viral hepatitis. Both conditions have a common genetic predisposition for concurrent immunological disease associated with human leukocyte antigen-DR4. The expression of smooth muscle antibodies and high-titer antinuclear antibodies is associated with human leukocyte antigen-DR4 in autoimmune hepatitis only, suggesting that this response is associated with triggering antigens and immune recognition systems that are different from those in viral disease.

Abstract
The relationship between alpha 1-antitrypsin deficiency (alpha 1-ATD) and the HLA antigen system was studied in 32 liver transplant recipients. Despite previous reports of an association of HLA antigen DR3 with homozygosity for alpha 1-AT ZZ, no such association was seen in this population of alpha 1-ATD homozygous ZZ patients with advanced hepatic disease. Thus, the reported association of HLA class II antigens and homozygosity for the Z allele for alpha 1-AT may be an artifact of either a small study population or geographic inbreeding and a coincidental association of certain HLA antigens with the presence of homozygosity for the Z allele of alpha 1-AT.

Abstract
It is known that the 5%-10% of adults infected with hepatitis B virus (HBV) develop a chronic infection and that HBV infection acquired at birth by an hepatitis B surface antigen (HBsAg)/hepatitis B "e" antigen (HBeAg)-positive mother almost invariably leads to chronic infection. Little information is, however, available about the risk of HBV infection acquired in childhood becoming chronic. We have, therefore, studied the chronicity rate of HBV infection in the families of 60 consecutive HBsAg-positive chronic carrier children. Of parents 81.5% and 78.6% of children showed serological evidence of past or ongoing HBV infection. The chronicity rate was significantly higher among children (73.4%) than parents (35.6%). Such a high chronicity rate in these children was not correlated with vertical transmission, since this was reported in only 1.7% of them. It is noteworthy that the chronicity rate of HBV infection was not significantly different between children of HBsAg-positive mothers and those in whom infection must have been horizontally transmitted because their mothers were HBsAg-negative. Although the families studied represent a selected sample and the role of genetic factors could not be excluded, our results seem to show that the most important factor in determining the outcome of infection is the acquisition of hepatitis B during childhood.

Abstract
In this preliminary study, children with chronic HBV hepatitis, as was also previously shown for adults, respond to interferon therapy in an HLA class I antigen dependent manner. If this can be confirmed on a large scale, HLA typing may serve as a useful indication of interferon-therapy responders.

Abstract
Alaska Natives have a high incidence of hepatocellular carcinoma (HCC), with regional, ethnic, village, and familial clustering. During 1969-1988, 15 of the 45 incident cases of HCC in Alaska Natives occurred in 5 families. This report presents epidemiologic, virologic, and immunogenetic data on these 5 families. The results of hepatitis B virus (HBV) serologic testing indicates that HBV infection was an important factor in 4 of the 5 families. Human lymphocyte antigen (HLA) testing was performed in 3 families. The HLA results are reviewed in relationship to the familial clustering of HCC.

Abstract
Chronic liver disease affects up to 20% of children with alpha 1-antitrypsin deficiency owing to the PiZZ genotype. Previous observations of a familial occurrence and abnormal immune responses to liver antigens in these patients suggests that immunoregulatory genes may be involved in the pathogenesis of liver damage. We have identified HLA phenotypes and class II (HLA-DR) gene polymorphisms in 140 white PiZZ subjects, of whom 92 (83 index patients) had liver disease, and 206 first-degree relatives. DR3* was present in 35 of 75 (46.7%) unrelated patients with liver disease compared with 5 of 28 (17.8%) patients without (p less than 0.01) and 23 of 100 controls (p less than 0.001). DR4 was increased in patients without liver disease; it was present in 17 of 28 (60.7%) compared with 29 of 75 (38.7%) patients with liver disease (p less than 0.05) and 36 of 100 controls (p less than 0.025). Using Southern blot analysis with HLA-DRB and DQB DNA probes, we identified two polymorphisms of DR3, only one (Dw25) of which is raised in PiZZ individuals with liver disease (9 of 55: 16.4%) compared with 1 of 23 (4.4%) without and 2 of 52 (3.9%) controls (p less than 0.05). Analysis of the segregation of HLA haplotypes in 77 families revealed no concordance for liver disease with HLA in those with affected sibships, indicating that, although DR3-Dw25 is associated with liver disease in alpha 1-antitrypsin deficiency, other factors must play a pathogenic role.

Abstract
HLA-A,B,DR antigens of two groups, one of normal individuals (N- = 31) and another of CRF (Chronic Renal Failure) patients (K- = 37), who did not develop anti-HBs protective antibodies after Hepatitis B (HB) vaccination, were compared, respectively, to the HLA antigens of two corresponding control groups (N+ = 52, K+ = 49), who responded to the vaccine. A statistically significant difference (Pc less than 0.02) in the frequency of HLA-DR3 was observed between responders and non-responders. An increased frequency of HLA-A1 and HLA-B8 in N- as well as of HLA-A1 and HLA-B35 in K- was also noticed, but this was not of statistical significance. As these antigens have been associated to both HBs antigenemia as well as chronic active hepatitis, we suggest that these genes or other genes in linkage to those may suppress the response to HBV vaccination while, in parallel, they may predispose to an autoimmune course of Hepatitis.

Abstract
The possible role of HLA phenotypes was investigated in the development of juvenile liver disease in persons with alpha 1-antitrypsin deficiency. Seventeen patients were investigated between the ages of 3-25 years. All of them had alpha 1-antitrypsin phenotype PiZ. After a longer follow-up a clinical diagnosis was established by the help of physical status, biochemical liver function tests and--in the cases of suspected liver disease--liver biopsy. The clinical course was correlated to the HLA phenotypes of the patients. In 2 cases all first degree relatives were investigated, as well. Our studies on the 17 unrelated patients indicated no correlation between HLA and juvenile liver disease in alpha 1-antitrypsin deficiency. The family studies confirmed these findings.

Abstract
The course after hepatitis B virus infection seems to be determined by the host's immune response, which in turn may be regulated by the major histocompatibility complex. In order to find a possible relationship between the course of disease and the phenotype frequency of HLA determinants, we studied 396 Dutch subjects of northern European local race. Six groups of individuals with various courses after hepatitis B virus infection were compared to healthy controls. The hepatitis B patients were grouped according to standard criteria: 47 had recovered from acute symptomatic hepatitis B virus infection; 60 had recovered from asymptomatic hepatitis B virus infection; 26 were asymptomatic hepatitis B surface antigen carriers; 16 had chronic persistent hepatitis B; 37 had chronic active hepatitis B, and 10 had chronic active hepatitis after elimination of hepatitis B antigens. Twenty-nine Class I and 13 Class II HLA antigens were assayed by standard microlymphocytotoxicity tests. The phenotype frequency of the Class II antigen DQw1 appeared to be significantly lower in patients with chronic active hepatitis B virus infection. Some other HLA specificities showed deviations from control values, but they were not statistically significant after correction for the number of antigens tested. In conclusion, we have found no evidence that the elimination of hepatitis B virus is related to HLA phenotype. DQw1, however, may affect the morphologic type of chronic hepatitis B infection, since its presence may protect against chronic active hepatitis.

Abstract
In order to study the genetic risk of alcoholic cirrhosis, the frequency of 26 HLA-A and -B antigens was compared in 184 normal controls, 175 alcoholic cirrhotic patients and 83 alcoholic patients with hepatic steatosis of carefully selected ethnic origin. Eight HLA-DR antigens were also determined in 95 subjects of the normal control group and 63 patients of the alcoholic cirrhosis group. The incidence of hepatitis B virus antibodies (anti-HBc and anti-HBs) was defined in 74 patients of the alcoholic steatosis group, 170 patients of the alcoholic cirrhosis group and 111 normal controls different from the previously mentioned normal control group. The incidence and the titers of cytomegalovirus and rubella antibodies were also determined in 93 patients of the alcoholic cirrhosis group and the 111 normal controls. Serum immunoglobulin concentrations were measured in the same 93 cirrhotic patients. Compared with the controls, the alcoholic cirrhosis group revealed a significantly higher frequency of HLA-B15 (21.7 vs. 9.8%, p less than 0.00025, corrected p less than 0.050) and HLA-DR4 (38.1 vs. 17.9%, p less than 0.005, corrected p less than 0.050) and a significantly lower frequency of HLA-B13 (2.9 vs. 11.4%, p less than 0.025, corrected p less than 0.050). As for the frequency of all other HLA antigens, there was no significant difference between the three groups (normal controls, alcoholic cirrhosis and alcoholic steatosis).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The hepatitis delta virus (Delta) is a defective RNA pathogen dependent for replication on obligatory helper functions provided by the hepatitis B virus (HBV). The virion is a particle of 35-37 nm, which encloses within a HBsAg coat the RNA genome and the Delta antigen, the specific immunologic expression of the new pathogen. Infection is diagnosed by the presence of Delta antigen in liver and the finding of antibody to Delta in serum. The virus is infectious for primates but can also adapt to non-primates. Distribution is world-wide with peak prevalence in the Mediterranean basin, the Middle East and areas of Africa. Transmission occurs by direct parenteral inoculation and by non-parenteral routes linked to close body contacts. Delta is highly pathogenic and a cause or an aggravating factor of HBsAg-positive liver disease. Infection superimposed on acute HBV hepatitis may induce a fulminant illness. Superinfection of carriers of HBsAg may convert a previously asymptomatic carrier in a carrier with chronic hepatitis, or accelerate the downward clinical course of chronic underlying HBV disease. Carriers of HBsAg probably represent the reservoir of the virus.
