RESUMO
BACKGROUND: Hepatitis B can be defined as one of the dangerous diseases caused by the hepatitis B virus (HBV), which infects the liver and causes liver failure, cirrhosis, and death. AIMS: This study aimed to evaluate the D-dimer, C-reactive protein (CRP), and autoantibodies markers among HBV-infected patients in Babylon province, Iraq, compared to a healthy control group. METHODS: In this cross-sectional study, all patients referred to GIT and liver centers in Merjan Medical City, Babylon, Iraq from January 2016 to January 2018 were screened for HBV infection by quantitative real-time polymerase chain reaction (qPCR). Antinuclear antibody (ANA), dsDNA, D-dimer, and CRP markers were examined using fluorescence technique in randomly selected patients and some healthy individuals as control group. Statistical analysis was performed using SPSS program. RESULTS: In this study, 424 HBV patients from different areas of Babylon province, Iraq were enrolled. A total of 40 patients and 15 healthy participants were selected for evaluation of D-dimer, CRP, ANA, and dsDNA levels. The results of the distribution of HBV-infected patient by gender per area revealed that males accounted for a higher percentage than females in all parts of Babylon provinces. Also, a highly significant increase in serum levels was observed in the patients compared to the control subjects for all the studied parameters D-dimer, ANA, dsDNA, and CRP. Overall, 5.5% of HBV patients (3/40) had a positive ANA titer. None of the HBV patients had a positive dsDNA titer. CONCLUSION: This study showed that, HBV-infected patients had elevated levels of D-dimer and CRP compared to the control group. Also, the seropositivity titers of ANA and anti-dsDNA autoantibodies were low in Iraqi HBV patients.
