A systematic review on the use of C-reactive protein in autopsy practice.

Postmortem analysis of C-reactive protein (CRP) in autopsies has been extensively researched for its potential utility. This analysis could aid forensic pathologists in screening for and investigating the potential infectious or inflammatory causes of death, thereby guiding appropriate autopsy procedures. To assess the diagnostic accuracy of postmortem CRP analysis in autopsy settings, a thorough electronic literature search was conducted across databases such as PubMed, Scopus, Web of Science, and Cochrane Library. Two independent reviewers screened eligible studies, followed by a methodological quality assessment using the QUADAS-2 checklist. Utilising a random-effects model, hierarchical summary receiver operating characteristic (HSROC) curve analysis and bivariate model meta-analysis were performed to evaluate heterogeneity across studies. Of the 1286 studies initially identified, nine met the eligibility criteria for the final analysis. The pooled sensitivity of postmortem CRP analysis was 0.93 (95% CI, 0.76, 0.98), with a pooled specificity of 0.80 (95% CI, 0.71, 0.87). The prevalence across studies ranged from 0.23 to 0.68, with a median of 0.5. Moderate variability was observed in the heterogeneity assessment across the primary studies. In summary, the study findings indicate that postmortem serum CRP analysis demonstrates high diagnostic accuracy with moderate heterogeneity. Additionally, postmortem CRP testing may be useful as a screening tool in autopsy practice to rule out the likelihood of sepsis. [ABSTRACT FROM AUTHOR]
