RESUMO
Objective To compare the clinical effect of the conventional detection and detection of hepatitis B virus large protein , aiming at improving the detection rate of hepatitis B .Methods According to the principle of random selection ,80 cases of hepatitis B patients ,from September 2016 to February 2017 in our hospital ,were selected and were randomly divided into two groups ,40 ca-ses in the control group ,40 cases in the observation group .The observation group was adopted the detection of hepatitis B virus large protein while the control group were treated by conventional detection method .The detection rate of two groups was com-pared .Results The positive rate of hepatitis B virus infection by Real-timePCR for detection in observation group was 86 .25%(69/80) ,which was higher than 72 .50% (58/80) in control group by ELISA ,and the difference was statistically significant (P<0 .05) .The positive rate of HBV-DNA in control group was 77 .50% (31/40) which was lower than 90 .00% (36/40) in observa-tion group ,and the difference was statistically significant (P<0 .05) .Conclusion The conventional detection method and detection of hepatitis B virus large protein both can detect the hepatitis B virus ,and detection rate of detection of hepatitis B virus large pro-tein was higher .Detection of hepatitis B virus large protein is recommended for the detection of hepatitis B virus in order to reduce the misdiagnosis rate .
RESUMO
Objective@#To investigate the comparative study of serum hepatitis B virus (HBV) large protein (HBV-LP) , HBV-DNA, and Pre S1 antigen (Pre S1-Ag) detection in the evaluation of serum HBV replication in patients with chronic hepatitis B.@*Methods@#A total of 482 patients infected with chronic hepatitis B virus (CHB) were enrolled and the serums were collected in a hospital of Hefei city in Anhui province from June 2013 to March 2015. The serum HBV-LP, HBV markers(HBV-M) and Pre S1-Ag were detected using ELISA, and HBV-DNA were quantified using quantitative real-time PCR. The positive detection rate difference of HBV-DNA, HBV-LP and Pre S1-Ag were compared, the correlation between the logarithm of HBV-DNA copies number and the absorbance value of HBV-LP was analyzed using Spearman rank correlation.@*Results@#The positive rates of HBV DNA, HBV-LP, and Pre S1-Ag were 67.22% (324/482), 73.86% (356/482), and 37.34% (180/482), respectively (P<0.01). The positive rates of the three markers were 54.57% (185/339), 64.90% (220/339), and 27.73% (94/339), respectively, in 339 HBeAg-negative CHB patients (P<0.01). In HBeAg negative patients, the positive rate of HBV-LP in 185 cases of HBV-DNA positive samples was 90.81% (168/185), which was higher than that of Pre S1-Ag with rate of 39.46% (73/185) (P<0.01).The positive rate of HBV-LP was 33.77% (52/154) in 154 cases of patients with negative HBV-DNA whose positive rate was higher than Pre S1-Ag with positive rate of 13.64% (21/154)(P<0.01). The positive rates of HBV-DNA, HBV-LP and Pre S1-Ag in HBsAg, HBeAg and HBcAb positive groups were 97.04% (131/135), 94.81% (128/135), and 60.00% (81/135), (P<0.01); The positive rates of three indexes of HBsAg, HBeAb, HBcAb positive group were 53.74% (122/227), 63.88% (145/227), and 27.31% (62/227); The positive rates of three indexes of HBsAg and HBcAb positive group were 55.79% (53/95), 67.37% (64/95), and 28.42% (27/95) (P<0.01). The absorbance value of HBV-LP was positively related with the logarithm of HBV-DNA copies number (Spearman rank correlation coefficient was 0.908, P<0.01).@*Conclusion@#There was a good correlation between HBV-LP and HBV-DNA load value, and could be used as an effective complement for the detection of HBV-DNA and HBV-M. Compared with Pre S1-Ag.
RESUMO
Objective To analyze the relationship among serum hepatitis B virus (HBV ) envelope large protein (HBV‐LP ) , HBV‐DNA and HBV marker(HBV‐M ) for investigating the clinical significance of HBV‐LP to reflect the HBV in vivo replication in the patients with HBV infection .Methods Total 540 cases of chronic HBV infection treated in the Longgang District Hospital of Traditional Chinese Medicine from April 2013 to September 2015 were selected .The real‐time fluorescence quantitative PCR meth‐od was used to detect serum HBV‐DNA ,HBV‐LP and HBV‐M were detected by the enzyme linked immunosorbent assay (ELISA) . The correlation among HBV‐LP ,HBV‐M and HBV‐DNA were analyzed .Results The positive rate of HBV‐LP in HBeAg‐positive patients was 96 .39% ,and which of HBV‐DNA was 93 .33% ,there was no statistically significant difference between them (P>0 .05);The serum HBV‐LP level was positively related with the logarithmic value of HBV‐DNA copies ;the positive rate of HBV‐LP in HBeAg‐negative patients was 63 .33% ,and which of HBV‐DNA was 51 .11% ,the difference between them was statistically significant(P<0 .05) .Conclusion HBV‐LP can effectively reflect the HBV in vivo replication in the patients with chronic hepatitis B and its sensitivity is higher than that of HBeAg ,HBV‐LP can even more reflect the HBV in vivo replication status in patients with HBeAg‐negative chronic hepatitis B .
