Abstract

Aim: Since data about prevalence of JC virus in Iranian population is scarce, this study was designed to evaluate the prevalence of JC virus in healthy individuals who had attended Fajr hospital and Farjam clinical laboratory in Tehran, Iran.

Background: JC virus is the causative agent of progressive multifocal encephalopathy (PML) in individuals with suppressed immune system. There are some evidences that this virus is responsible for some forms of cancers for example colorectal and gastric cancers in humans.

Patients and methods: Urine samples from 133 healthy individuals older than 18 years old were collected and after extraction of viral DNA, PCR was performed to determine the presence of virus. Results of the test and demographic data of subjects were entered into SPSS program and were analyzed by it.

Results: 71 subjects were male and 62 individuals were female. Mean age of the population was 42.23 ± 13.47. From the total number of 133 subjects, 51 (38.3%) individuals were positive for the presence of JC virus. Gender had statistically significant relationship with JC virus presence (p= 0.042). Age was not significantly related to JC virus presence status (p= 0.3).

Conclusion: Obtained rate of JC prevalence in this study is similar to the results of studies in India and Philippine. Because of this virus’s role in AIDS and the role of this virus in gastrointestinal cancers have been revealed in recent years, the more extended studies on the prevalence of this virus in different populations in Iran is necessary.
