Abstract:
BACKGROUND:Cytomegalovirus is one of the opportunistic infection viruses for organ transplant patients, and it can lead to functional loss of organ grafts and even endanger lives. Therefore, accurate diagnosis of cytomegalovirus infection at early phase is the key to clinical treatment. OBJECTIVE:To analyze the detection method, accuracy, detection time and clinical significance of cytomegalovirus infection after organ transplantation. METHODS: A computer-based search of VIP, PubMed and CNKI as wel as manual search of books were performed for literatures concerning organ transplantation and cytomegalovirus infection published from January 2007 to December 2014. The keywords were transplantation, cytomegalovirus in English and Chinese, respectively. Total 1 894 papers in English and 31 articles in Chinese were found. Among them, only 35 papers which were highly representative and published in related authoritative journals were chosen for further analysis. RESULTS AND CONCLUSION:The main non-invasive detection of cytomegalovirus infection is stil the test of CMV-pp65 antigen with good sensitivity and specificity which can accurately reflect the status of cytomegalovirus infection. This method is also the most important clinical diagnostic method. Molecular biological detection of cytomegalovirus can detect potentialy infected people, and this method can detect the infection earlier than CMV-pp65 antigen method, which is suitable for the early diagnosis of cytomegalovirus infection and early drug treatment. Quantitative nucleic acid test can be used to analyze cytomegalovirus-DNA copies so as to determine the concentrations of the virus in patients, which may provide a more sensitive monitoring way for inapparently infected patients. Cytomegalovirus-IgG and cytomegalovirus-IgM in serum can be used to determine whether organ transplant recipients have been infected by cytomegalovirus. Virus culture and histological examination have been used for several years, both of which are the gold standard for detecting cytomegalovirus. However, these methods cannot be used in early diagnosis and active infection. Immunological detection method provides a new ideal for the diagnosis of cytomegalovirus infection. This method can monitor cytomegalovirus infection from early phase accurately and assess the risk of cytomegalovirus, providing a new way for the development of the diagnosis of cytomegalovirus infection.
