Significance of hepatitis B core antigen in the liver in patients with chronic hepatitis B and its relation to hepatitis B virus DNA

Liver biopsies from 52 patients with chronic hepatitis B were investigated for the presence and distribution of HBcAg and the results were compared with the status of hepatitis B virus deoxyribonucleic acid (HBV-DNA). The patients consisted of 37 men and 15 women, aged 16-55 years (mean = 34 years). Serum alanine aminotransferase (ALT) was elevated in 50 patients (range: 18-969 U/L; mean = 290 U/L). Serological testing showed HBsAg in all, HBeAg in 45 (87%), and HBV-DNA in 28 (54%). Liver biopsies demonstrated HBcAg in 35 (67%) patients. HBcAg was not only present in 31 of 45 (69%) patients who were seropositive for HBeAg, but also in four of seven (57%) with antibody to HBeAg (anti-HBe). In 28 of 35 (80%) patients with HBcAg in the liver, serum HBV-DNA was detected. However, no serum HBV-DNA was detected in 17 patients who had no detectable HBcAg in the liver. The distribution of HBcAg in the liver was rather cytoplasmic and nuclear than nuclear alone. Among 33 patients with cytoplasmic HBcAg in the liver, 15 (45%) had an evidence of acute exacerbation of hepatitis with marked ALT elevation (range: 168-894 U/L; mean = 385 U/L) and nine patients showed severe chronic active hepatitis and confluent necrosis, histologically. These results indicate that the presence of HBcAg in the liver correlates with the amount of circulating hepatitis B virus as quantified by serum level of HBV-DNA. The predominant cytoplasmic HBcAg in the liver may suggest the possibility of multiple episodes of acute exacerbation and more severe ongoing hepatitis during the clinical course.     

慢性乙型肝炎患者ALT、HBV DNA及血清肝纤维化标志物与肝纤维化程度的关系

目的探讨ALT、HBV DNA以及血清纤维化标志物透明质酸(HA)、层粘连蛋白(LN)、Ⅲ型前胶原肽(PⅢP)、Ⅳ型胶原(CⅣ)与慢性乙型肝炎肝纤维化程度的关系。方法检测281例慢性乙型肝炎患者血清中ALT、HBV DNA和纤维化标志物(HA、LN、PⅢP及CⅣ)的水平,并行肝活检检测肝组织病理纤维化分期。结果 HBeAg阴性慢性乙型肝炎患者HBV DNA水平较低、纤维化程度较高。HBeAg阳性患者纤维化程度与HBV DNA呈负相关(r=-0.251,P<0.001),S≥3组水平最低。慢性乙型肝炎患者纤维化程度与PⅢP水平呈正相关,其水平随着纤维化程度的加重而明显升高。结论 PⅢP水平可能作为评估慢性乙型肝炎患者肝纤维化程度的血清学指标,血清HBV DNA与肝脏纤维化严重程度的关系仍需进一步深入探讨。     

Circulating IL-2, IL-10 and TNF-alpha in chronic hepatitis B: their relations to HBeAg status and the activity of liver disease

BACKGROUND/AIMS: Preferential production of immunoregulatory cytokines may play an important role in the pathogenesis of chronic hepatitis B. We aimed to determine the serum levels of IL-2, IL-10 and TNF-alpha in patients with chronic hepatitis B and to correlate these findings with the activity of liver disease, HBeAg/anti-HBe status and replication level of the virus. METHODOLOGY: Seventy-two chronic hepatitis B patients were categorized into 4 groups according to activity of liver disease and HBeAg status. Group 1 (n = 13): HBeAg and HBV DNA-positive with persistently normal ALT. Group 2 (n = 20): HBeAg and HBV DNA-positive patients with persistently elevated ALT. Group 3 (n = 19): HBeAg and HBV DNA-negative patients with persistently normal ALT. Group 4 (n = 20): HBeAg-negative patients with persistently elevated ALT and variable serum HBV DNA. IL-2, IL-10 and TNFa levels were determined in stored patient sera. RESULTS: Apart from group 1 patients, all patients groups had higher IL-2 levels compared to controls suggesting that IL-2 production is increased when liver disease becomes active in HBeAg-positive phase of HBV infection. Only group 2 patients had elevated IL-10 levels compared to controls. None of the HBeAg-negative patients had detectable TNF-alpha levels while 64% HBeAg-positive patients had elevated levels of TNF-alpha irrespective of the activity of liver disease. Except TNF-alpha, no association was found between HBV DNA status and the presence or absence of detectable cytokines in circulation. CONCLUSIONS: Our results suggest that circulating cytokine profile in chronic hepatitis B is related with the HBeAg status, replication level of the virus and the activity of liver disease.     

Serum soluble interleukin-2 receptor levels in patients with chronic hepatitis B virus infection and its relation with anti-HBc

AIM:To investigate the relationship between serumsoluble interleukin-2 receptor(sIL-2R)level and anti-HBcin patients with chronic hepatitis B virus(HBV)infection.METHODS:Sera from 100 patients with chronic HBVinfection and 30 healthy controls were included in thisstudy.The patients were divided into group A[HBsAg( ),HBeAg( )and anti-HBc( ),n=50]and group B[HBsAg( ),HBeAg( )and anti-HBc(-),n=50].sIL-2R levelswere determined using ELISA.HBV DNA and alanineaminotransferase(ALT)were also detected.RESULTS:Serum sIL-2R levels were significantly higherin patients with chronic HBV infection than in healthycontrols.Moreover,serum sIL-2R levels were significantlyhigher in patients with HBsAg( ),HBeAg( )and anti-HBc( )(976.56±213.51×10~3 U/L)than in patients withHBsAg( ),HBeAg( )and anti-HBc(-)(393.41±189.54×10~3 U/L,P<0.01).A significant relationship was foundbetween serum sIL-2R and ALT levels(P<0.01)inpatients with chronic HBV infection,but there was nocorrelation between sIL-2R and HBV DNA levels.Theanti-HBc status was significantly related to the age ofpatients(P<0.01).CONCLUSION:The high sIL-2R level is related topositive anti-HBc in chronic hepatitis B patients.Positiveanti-HBc may be related to T-lymphocyte activation andnegative anti-HBc may imply immune tolerance in thesepatients.     

Extended lamivudine treatment in patients with chronic hepatitis B enhances hepatitis B e antigen seroconversion rates: results after 3 years of therapy

A study in Chinese patients with chronic hepatitis B showed that treatment with lamivudine for 1 year significantly improves liver histology and enhances hepatitis B e antigen (HBeAg) seroconversion compared with placebo. Fifty-eight patients from this 1-year study have received long-term treatment with lamivudine 100 mg; the outcome of 3 years of lamivudine is reported here. Before treatment, all patients had detectable HBeAg. HBeAg seroconversion (HBeAg-negative, anti-HBe-positive), hepatitis B virus (HBV)-DNA suppression, alanine transaminase (ALT) normalization, emergence of YMDD variant HBV, liver histology, and long-term safety were assessed. After 3 years of continuous treatment with lamivudine 100 mg daily, 40% (23 of 58) of patients achieved HBeAg seroconversion. In patients with baseline serum ALT >2 x upper limit of normal (ULN), the rate of HBeAg seroconversion was 65% (17 of 26). Median serum HBV-DNA concentrations were below the level of detection, and median ALT concentrations were within the normal range throughout 3 years of treatment. YMDD variant HBV emerged in 33 of 58 (57%) patients during the 3 years, of whom 9 (27%) achieved HBeAg seroconversion (6 after emergence of YMDD variant HBV). ALT levels and histologic scores after emergence of YMDD variant HBV did not show major deterioration. Lamivudine was well tolerated during 3 years of therapy. In conclusion, these data in Chinese patients with chronic hepatitis B show enhanced seroconversion rates with extended lamivudine treatment. Up to two thirds of patients with moderately elevated pretreatment ALT achieved HBeAg seroconversion after 3 years of therapy.     

Rate of YMDD motif mutants in lamivudine-untreated Iranian patients with chronic hepatitis B virus infection.

BACKGROUND: Lamivudine is used for the treatment of chronic hepatitis B patients. Recent studies show that the YMDD motif mutants (resistant hepatitis B virus) occur as natural genome variability in lamivudine-untreated chronic hepatitis B patients. In this study we aimed to determine the rate of YMDD motif mutants in lamivudine-untreated chronic hepatitis B patients in Iran. PATIENTS AND METHODS: A total of 77 chronic hepatitis B patients who had not been treated with lamivudine were included in the study. Serum samples from patients were tested by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for detection of YMDD motif mutants. All patients were also tested for liver enzymes, anti-HCV, HBeAg, and anti-HBe. RESULTS: Of the 77 patients enrolled in the study, 73% were male and 27% were female. Mean ALT and AST levels were 124.4+/-73.4 and 103.1+/-81 IU/l, respectively. HBeAg was positive in 40% and anti-HBe in 60% of the patients. Anti-HCV was negative in all of them. YMDD motif mutants were not detected in any of the patients despite the liver enzyme levels and the presence of HBeAg or anti-HBe. CONCLUSION: Although the natural occurrence of YMDD motif mutants in lamivudine-untreated patients with chronic hepatitis B has been reported, these mutants were not detected in Iranian lamivudine-untreated chronic hepatitis B patients.

Profile of hepatitis B e antigen-negative chronic hepatitis B.

BACKGROUND: Although chronic hepatitis B occurs in hepatitis B e antigen (HBeAg)-negative patients, its prevalence and clinical significance are not known. AIM: To determine the prevalence and profile of HBeAg-negative chronic hepatitis B virus (HBV) infection. METHODS: A retrospective analysis of 363 consecutive patients (mean age 36 y; 288 men) with chronic HBV infection was performed. All patients were HBsAg-positive. Tests for liver profile, HBeAg and anti-HBe antibody were performed in all patients. Serum HBV DNA was tested using branched DNA assay in 245 patients. The patients were classified into three groups: no cirrhosis with normal ALT levels, no cirrhosis with elevated ALT levels, and clinical or histological evidence of cirrhosis. RESULTS: Of 363 patients, 141 (39%) were HBeAg-positive and 222 (61%) HBeAg-negative. Of HBeAg-negative patients, 120 (54%) had normal ALT, 45 (20%) had elevated ALT and 57 (26%) had evidence of cirrhosis; corresponding figures in the HBeAg-positive patients were 40 (28%), 66 (47%) and 35 (25%). HBV DNA was positive in 53 of 131 (40%) HBeAg-negative patients tested; of these 53 patients, 9 (17%) had normal ALT, 20 (38%) had elevated ALT and 24 (45%) had cirrhosis. Thus, 72% of HBeAg-positive and 46% of HBeAg-negative patients had elevated ALT and/or cirrhosis. Among the latter group, 83% of HBV DNA-positive patients had elevated ALT and/or cirrhosis. Overall, 18% of HBsAg-positive patients had HBeAg-negative, HBV DNA-positive liver disease. CONCLUSION: HBeAg-negative chronic hepatitis B is not an uncommon and benign entity and chronic liver disease develops in a significant proportion of such patients.
