Sepsis is a global problem in either developing or developed countries and it is expected that the number of patients with sepsis and septic shock will tremendously increase in next decades also because of the antibiotic resistance growing issue worldwide. Criteria for sepsis diagnosis and prognosis have been recently established, but still a further understanding of the role of biomarkers in this setting is needed. Better utilization of biomarkers such as white blood cell count, CRP, lactate, procalcitonin, presepsin and bioadrenomedullin in sepsis patients, a state of the art on how to use them is needed. This review will focus on the actual recognized role of sepsis biomarkers not only for diagnosis purpose but also to improve patients treatment results in order to reduce mortality, hospital length of stay and cost related.
Background : This study aimed to analyze the relationship between quantitative hepatitis B surface antigen and hepatitis B virus deoxyribonucleic acid in hepatitis B e antigen-positive and hepatitis B e antigen-negative chronic hepatitis B patients and to determine the best cut-off value for quantitative hepatitis B surface antigen to predict high hepatitis B virus deoxyribonucleic acid levels (≥2000 IU/mL). Methods: Ninety-seven sera from chronic hepatitis B patients were collected in this study. Hepatitis B virus deoxyribonucleic acid levels were quantified by real-time polymerase chain reaction. Quantitative hepatitis B surface antigen and hepatitis B e antigen levels were determined by two-site sandwich chemiluminescence immunoassay. Alanine transaminase levels were measured by the International Federation of Clinical Chemistry-approved methods. Results: A significant correlation between quantitative hepatitis B surface antigen and hepatitis B virus deoxyribonucleic acid levels was observed in hepatitis B e antigen-positive group ( r = 0.453, P = .002), but not in hepatitis B e antigen-negative group ( r = 0.117, P = .454). No significant correlation between quantitative hepatitis B surface antigen and alanine transaminase was found in the hepatitis B e antigen-positive group ( r = 0.521, P = .241). However, a significant correlation was shown between quantitative hepatitis B surface antigen and alanine transaminase levels in the hepatitis B e antigen-negative group ( r = 0.455, P = .001). The best cut-off value of quantitative hepatitis B surface antigen for predicting high hepatitis B virus deoxyribonucleic acid levels was 3.422 × 10 3 IU/mL. Conclusion: Correlation between quantitative hepatitis B surface antigen and hepatitis B virus deoxyribonucleic acid levels is significant in the hepatitis B e antigen-positive group. Quantitative hepatitis B surface antigen can be used to predict high hepatitis B virus deoxyribonucleic acid levels in the hepatitis B e antigen-positive group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
