Objective To investigate the cognition influencing factors of regular laboratory monitoring of HBeAg negative in chronic HBV infection,and analyze the related factors of HBeAg conversion. Methods From January 2015 to March 2017,a total of 302 chronic HBV infected patients in Jinin Infectious Disease Hospital were investigated with a questionnaire about disease related cognition. Single factor and multiple factors Logistic regression analysis was used to analyze the influencing factors of regular monitoring behavior and HBeAg conversion. At the same time,163 cases of HBeAg negative HBV infection were divided into the two groups: regular and irregular monitoring, and disease related laboratory tests and the outcomes were analyzed. Results Psychological pressure(OR = 4. 339, 95％ CI:1. 322 - 14. 243),antiviral treatment( OR = 5. 149,95％ CI:1. 628 - 16. 283),knowledge of hepatitis B (OR = 3. 306,95％ CI:1. 108 - 9. 867) and the stability of disease(OR = 3. 229,95％ CI:1. 094 - 9. 528) were the regular monitoring promoting factors(all P < 0. 05). Antiviral therapy(OR = 0. 298,95％ CI:0. 108 - 0. 822),virus gene mutation(OR = 0. 202,95％ CI:0. 048 - 0. 856),and duration of disease(OR = 0. 340,95％ CI:0. 122 - 0. 949) were related factors of HBeAg conversion(all P < 0. 05). The serum levels of ALT,ALB,AFP and HBV - DNA in the HBeAg negative regular monitoring group were (68 ± 34) IU/ L, (40 ± 12) g/ L, (23. 0 ± 5. 9) μg/ L, (2. 0 ± 1. 3)copies/ mL,respectively,which in the non - regular monitoring group were (126 ± 56) IU/ L,(35 ± 10) g/ L, (78. 0 ± 12. 8)μg/ L,(3. 9 ± 1. 7) copies/ mL,respectively,the differences were statistically significant (t = 2. 323, 2. 097,2. 109,2. 234,all P < 0. 05). Conclusion HBeAg negative patients is a key group to monitor and control disease progression. Regular laboratory monitoring is better. Medical staff should enhance patients' cognition education and improve disease control rate.
