The Role of NT-proBNP as Prognostic Biomarker for Preeclampsia Complications: A Systematic Review Protocol

Abstract

\n Background There are two central dogmas between the pathophysiology of preeclampsia, the placental origin and the extra-placental origin. Recent findings found that women with a history of preeclampsia are at higher risk of cardiovascular disease and death because of cardiovascular disease. This finding leads to the extra-placental origin. During normal pregnancy, the maternal cardiovascular system undergoes modification. However, hemodynamic and vascular modification are disrupted in women who develop preeclampsia. NT-proBNP is a biomarker that indicates the disruption of the cardiovascular system and can predict the complication of preeclampsia. Based on that information, we would like to investigate the roles of NT-proBNP plasma levels in predicting maternal and fetal complications of preeclampsia women. Besides, we also investigate the roles of NT-proBNP plasma levels in predicting the severity and onset of preeclampsia women and the sensitivity and specificity of NT-proBNP plasma levels in preeclamptic women.MethodsWe designed and registered a study protocol for a systematic review. This study aims to investigate the roles of NT-proBNP plasma levels in predicting maternal and fetal complications of preeclampsia women. The Cochrane Handbook for Systematic Reviews of Diagnostic Test Accuracy was used to structure our methodological approach and the Preferred Reporting Items for a Systematic Review and Meta-Analysis Protocols guidelines in reporting the findings of this review. We will search literature in Hinari, Cochrane Library, ScienceDirect, and Scopus database. Then, we will search the grey literature in OCLC’s OAISTER. Randomized controlled trials and observational studies will be included in the analysis. Three reviewers will independently screen articles, extract data, and evaluate for quality and bias using Newcastle-Ottawa Scale. Studies were included according to the following procedures: (1) Identification, Duplication of articles and non-original research articles will be excluded; (2) Title and Abstract Screening, RCT and observational studies and focused on NT-proBNP levels in preeclampsia; (3) Full-text availability; and (4) Full-text screening based on PICO criteria. Each outcome is synthesized by a qualitative or narrative approach. The results will be divided into certain points, namely (a) Selection of the studies, (b) Characteristics of the Eligible Studies, (c) Data Extraction of the Eligible Studies, and (d) Risk of Bias Analysis Results.Discussion A systematic review of the role of NT-proBNP as predicting biomarkers for preeclampsia complications will be conducted. This study can help predict the severity, onset, and complication of a pregnant woman with preeclampsia.
