ABSTRACT

Objective To research the reality of ELISA testing results with negative anti-HBc and positive antiHBe.Methods CMIA was carried out to retest antiHBc and antiHBe of 105 samples which were initially tested to have negative antiHBc and positive antiHBe.Results Among the 105 samples retested by CMIA,there were three different results,positive antiH-Bc with positive antiHBe,negative antiHBc with negative antiHBe and positive antiHBc with negative antiHBe,whose pro-portions were 72.38%,21.91% and 5.71% respectively;the fasle negative rates of antiHBc were 78.10% in total and 93.33%,96.15% and 47.37% in 3 subgroup with S/CO 1.00~ 1.20,1.20~2.00 and 2.00~ 3.00,respectively;the true positive rates of antiHBe were 72.38% in total and 42.86%,88.14% and 56.25% in 3 subgroups with S/CO 0.00~0.10, 0.10~0.80 and 0.80 ~ 1.00,respectively.Conclusion HBV-M results with negative antiHBc and positive antiHBe by ELISA could give suggestive value and not reflect true information about antiHBc and antiHBe with three alternatives which would be obtained through retesting by a second assay.

ABSTRACT

Objective To evaluate the clinical significance of chronic hepatitis B (CHB) with concurrent hepatitis e antigen (HBeAg) and antibody (anti-HBe) during antiviral therapy. Methods A total of 115 CHB patients with concurrent HBeAg and anti-Hbe detection during antiviral therapy were enrolled in this retrospective study. All patients received pegylated-IFN-alpha-2a (Peg-IFNα-2a, n = 50) or entecavir (ETV, n = 65) for antiviral treatment. Their biochemical virological and serological response and clinical outcome were detected and analyzed. Results Among the patients treated with Peg-IFNα-2a, 31 (62.0%) achieved HBeAg seroconversion and 6 (12.0%) achieved HBsAg seroconversion at the end of treatment. About 35.4% of patients, who received ETV, achieved HBeAg seroconversion and none of them achieved HBsAg seroconversion at the end of treatment (P < 0.05). Conclusion High rates of HBeAg seroconversion and HBsAg loss could be achieved in CHB patients, with co-existence of HBeAg and anti-HBe, who received Peg-IFNα-2a, but not ETV therapy.

ABSTRACT

Objective To explore the relationship among HBV DNA load, HBeAg/Anti-HBe and ALT in patients with chronic hepatitis B infection. Methods HBV markers in 134 patients with chronic HBV infection were detected by ELISA,and patients were divided into group Ⅰ (HBeAg +/Anti-HBe-,43 patients) ,group Ⅱ (HBeAg-/Anti-HBe + ,69 patients)and group Ⅲ (HBeAg-/Anti-Hbe-,22 patients)according to the results of presence of HBeAg/Anti-HBe. HBV DNA load and ALT were tested respectively by fluorescence quantitative polymerase chain reaction technology and successive monitor reaction. Results Both the positive rate and the HBV DNA load quantification in group Ⅰ were higher than in group Ⅱ and Ⅲ (P<0.01). Abnormality rate of ALT in HBV DNA positive patients was higher than the patients with HBV DNA negitive(P<0.01). There was no relationship between HBV DNA load and ALT in HBV DNA positive patients. Conclusion There was a certain corelation among HBV DNA load, HBeAg/Anti-HBe and ALT,but the active degree of HBV replication could not to be assessed by HBeAg/Anti-HBe or ALT alone. It was necessary for the padient with chronic HBV infection to examine them together.

ABSTRACT

To elucidate the biologic significause of hepatocyte B core antigen (HBcAg) expression and its relation to the natural course of hepatitis B virus (HBV) infection, we tried to correlate the patterns of HBcAg with the HBV replication state and with disease activity in 40 needle biopsies performed on hepatitis B surface antigen (HBsAg) carriers aged from 15 to 46 years. In 32 of 40 cases, HBcAg was present in the hepatocyte nucleus (nHBcAg), in the cytoplams (cHBcAg) or in both (mixed). Pure nHBcAg was seen only in minimal hepatitis, but a diffuse pattern of expression of cytoplasmic HBcAg and mixed cytoplasmic and nuclear expression of HBcAg were seen in active hepatitis. There was also a good correlation between liver HBcAg and serum HBeAg. Cases in which HBcAg expression were observed were positive for serum HBeAg (81%) and the cases negative for HBcAg were all positive for serum anti-HBe.

ABSTRACT

The clinical value of an enzyme-linked immunosorbent assay (ELISA) for the detection of anti-HBc IgM was evaluated by testing 202 sera from acute viral hepatitis B (AVHB), hepatitis B (HB), chronic hepatitis (CAH), chronic liver disease (CLD), cirrhosis, primary hepatoma, HBsAg carrier, acute viral hepatitis A (AVHA), hepatitis A (HA), non-A, non-B (NANB) hepatitis and miscellaneous conditions other than hepatic disease, and 19 additional various hepatic disease cases were examined for anti-delta. In clinical situations the accurate diagnosis of HB is not always possible and the differential diagnosis seems to be very important especially in making decisions of treatment and estimation of prognosis. In overall cases the highest positive rate of anti-HBc IgM was found in AVHB as shown as 74.3% (26/35) comparing to other conditions in which the positive rate was extremely low (2.1%). The anti-HBc IgM appeared to be highly specific to AVHB (83.9%) as compared to the other. The positive rate of HBsAg was high in AVHB, CAH and HBsAg carrier (100.0%) followed by CLD, cirrhosis and HB (up to 70.8%). The ALT activities and ALPalb fractions were significantly high in AVHB (p less than 0.005). The correlation between the positivity of anti-HBc IgM and highly abnormal ALT appeared be high. AVHB was confined mostly to 10-20 age group and the male to female ratio was about 6 to 1. Subgroup of AVHB II with positive anti-HBc IgM appeared to have a greater chance being positive for HBsAg and ALPalb. The S/N ratio of anti-HBc IgM was as high as 20 which was unique to AVHB.
