We have recently reported enhanced frequencies of polyom.virus infection in post-m.rtem.brain tissue of autistic patients com.ared to controls. To further explore potential contributions to neurodevelopm.ntal disorders by polyom.viruses, we have em.loyed specie-specific Taqm.n assays to assess the prevalence and titres of BKV, JCV and SV40 inthe urines of 87 patients with autism.spectrum.disorder, 84 controls m.tched by sex and age with the autistic sam.le, 15 subjects with Down syndrom. and 13 fragile X individuals. Prevalence rates of urinary BKV infection were significantly greater in Down syndrom. and fragile X patients com.ared to autistic and control individuals (P m.jority of patients who showed the presence of urinary genom.s, viral titres resulted significantly higher am.ng Down syndrom. patients (P m.ared to controls, autism.spectrum.disorder and fragile X individuals, who did not significantly differ from.each other. Our results are consistent with previous evidence supporting ham.ered im.unological surveillance and/or im.une deficits in fragile X and especially in Down syndrom. patients.
