Determining the prevalence of positive cases of IgM and IgG antibodies against Cytomegaloviruses in Shahid Motahari clinic in Shiraz during the years 2019 to 2023

Abstract

Background: Cytomegalovirus (CMV) stands out as a significant contributor to congenital viral infections, exhibiting a prevalence ranging from 40% to 90%. Cytomegalovirus has different effects on people, such that it appears without symptoms in people with a healthy immune system, but it leads to severe symptoms in infants and those with a weak immune system. To comprehend the disease's societal prevalence, seroepidemiological investigations are imperative. This study aims to ascertain the serum prevalence of cytomegalovirus and explore potential correlations between age, sex, and the prevalence of CMV in patients attending Shahid Motahari Clinic in Shiraz Methods: A cross-sectional descriptive study was undertaken on 2,469 individuals who assessed their cytomegalovirus antibody levels between March 2019 and February 2023 at Shahid Motahari clinic in Shiraz. The ELISA method was employed to evaluate CMV, and the obtained data were analyzed using SPSS version 19 software. Chi-square tests and Fisher's exact test were applied to examine the correlation between positive antibody results and age as well as gender. Results: Among the 2469 surveyed people, 658 people (26.65%) were men and 1811 people (73.35%) were women. Based on ELISA test, antibody titer was reported positive in 1157 people (46.9%), including 315 men and 842 women, and 1312 people (53.1%) had negative antibody titer. The highest number of positives is related to IgG, and in IgM, the test results are mostly negative. IgM prevalence showed no gender correlation but demonstrated a significant association with patient age. Meanwhile, IgG prevalence exhibited significant relationships with both age and gender Conclusion: Considering that the city of Shiraz is considered as one of the centers of treatment in the country and a large number of patients from all parts of the country and even neighboring countries come to this city for treatment and especially for the purpose of organ transplantation; also with Considering the 46.9% prevalence of CMV infection in the region, it is recommended to use preventive methods such as vaccine and immunotherapy against CMV infection in patients
