Abstract
Fatal acute myocarditis is a common cause of alleged medicolegal investigation. Forensic pathologists frequently encounter these death investigations, so it is an important disease we have to understand. The etiology of myocarditis is usually inferred from clinical information and preliminary laboratory studies. This study was undertaken to evaluate the molecular analysis of endomyocardial archive tissues in identifying the possibility of common DNA viral pathogens. We collected all available clinical record and endomyocardial archive tissues for patients who had myocarditis recorded as the clinical diagnosis at the National Taiwan University Hospital from 2001 to 2005. Findings for all available patients(6 men and 6 women;median age, 26 years)with myocarditis that fulfilled the Dallas criteria were included in this study. Twelve subjects who had died naturally except heart diseases served as control group from forensic autopsy. Nested polymerase chain reaction (PCR)was used for detection of DNA viral genomes (human herpes virus 1, human herpes virus 2, Epstein-Barr virus, and human herpes virus 5)from endomyocardial biopsied tissues. DNA viral nucleic acid were found in the hearts of 2 patients (16.7%), including human herpes virus 5(2 patient). In the control group, no viral genome was detected. In patients with unexplained myocarditis, viral infection really contributes to be an important etiology. We can’t realize which kinds of DNA viral infection based on only microscopic examination of endomyocardial biopsies. Serological tests can help these but it is time-consuming and not very specific. Nested polymerase chain reaction may be an sensitive and specific tool to identify viruses. Then, this may be given as a guide in treating patients in the future, such as viral vaccine prevention. It may be useful in forensic cases to identify the underlying virus infection.
