Abstract

Background and Objective: Cytomegalovirus (CMV), one of the most common opportunistic pathogens in patients infected with human immunodeficiency virus (HIV), can cause the diseases such as encephalitis, pneumonia, and chorioretinitis. This study aimed at molecular studying of CMV infection in individuals infected with the human immunodeficiency virus. Material and Methods: In this study, 50 venous blood samples from HIV-infected individuals were taken. Patients were divided into two categories: patients under treatment with and without antiretroviral drugs. Plasma were separated from blood samples and examined for the presence of cytomegalovirus genome by PCR. Material and Methods: this study was conducted on 50 blood samples from HIV-infected individuals, and plasma was separated and examined for the presence of cytomegalovirus genome by PCR. Patients were divided into two group of under treatment with and without antiretroviral drugs. Results: Of 50, 28 (% 56) were men and 22 (% 44) were women. CMV genome was identified in 8 samples (16%), and the molecular prevalence of CMV infection was 21.4% (n= 6) in males and 9.1% (n = 2) in females. Conclusion: Given the frequency of Cytomegalovirus Active Infection in HIV-infected individuals under antiretroviral therapy, we should be careful about the treatment of Cytomegalovirus Active Infection.

Abstract

Abstract Background and Objective: Human Cytomegalovirus (CMV) is an important cause of congenital viral infection that can lead to serious diseases and complications in infants. Application of rapid, sensitive, and specific HCMV detection methods is necessary for congenital infection detection. We aimed to optimize the use of PCR and ELISA for detection of HCMV in infants. Material and Methods: PCR–ELISA was performed by using specific primers and probe for detection of the HCMV glycoprotein B gene. First, the extracted DNA from urine samples and controls were labeled by digoxigenin during DIG-labeling PCR. After that, Biotin-labeled probe captured the DIG-labeled PCR products. The probe-PCR product hybrid is immobilized on a streptavidin-coated Microtiter plate, and detection was confirmed by proxidase-conjugated anti-digoxigenin antibody, and calorimetric substrate. Results: The clinical Human CMV strains isolated from16 patients were detected by this method. The optimized PCR-ELISA method was able to detect less than100 copies of HCMV genome. There was no non-specific reaction. Conclusion: PCR-ELISA can be applied as a sensitive, specific and reliable method for Semi-quantitative CMV detection in clinical samples. Keywords: Cytomegalovirus, Glycoprotein B, PCR-ELISA, Semi-Quantitative
