| Abstract: | Recurrent respiratory papillomatosis (RRP) is caused by human papillomaviruses (HPV) 6 and 11, but the role of their genomic variants in the disease's clinical course is unclear. This study investigated whether long-term persistence of a particular HPV genotype, subtype or genomic variant influences the RRP clinical course. HPV genotyping was performed in paired baseline and follow-up RRP laryngeal tissue specimens of 59 patients. HPV6 and HPV11 genomic variants were determined in paired tissue specimens taken at least 10 years apart in 20 selected patients. HPV was identified in 58/59 patients, most commonly HPV6 (40/58), followed by HPV11 (17/58). The most prevalent HPV genomic variant was HPV11 A2. HPV6 A and HPV6 B1 were most frequent in aggressive RRP. In all patients, identical HPV genomic variants were identified in both paired specimens. RRP results from a long-term infection with the same HPV genomic variant that can be identified decades after disease onset. We report the longest duration of genetically confirmed persistent HPV infection in peer-reviewed literature, during a 44-year interval in a patient with HPB6 B1. This study suggests that infection with a particular HPV genotype, subtype, or genomic variant does not significantly influence the clinical course of RRP. |
