Abstract/OtherAbstract:
Juvenile recurrent respiratory papillomatosis is caused mainly by human papillomavirus genotypes 6 or 11, acquired at birth or during pregnancy from an infected mother. Recurrent respiratory papillomatosis is characterized by recurring warts growing most commonly in the larynx. Multiple surgical procedures and the risk of airway obstruction contribute to the devastating impact of this disease. Some children will go into remission after a few surgeries whereas others will require repeated interventions over several years. Further understanding of the risk factors associated with severity may contribute to tailored treatments. A retrospective study of cases diagnosed between January 1995 and December 2008 was conducted to study determinants of severe forms of juvenile recurrent respiratory papillomatosis. Demographic and clinical variables were abstracted from children's medical charts and mothers' delivery charts. Viral factors (HPV genotyping and viral load) were studied from archived biopsies. Specific HLA class II alleles and killer-cell immunoglobulin-like receptors genes were tested from saliva samples. Logistic regression was performed to identify risk factors for severity. Overall, 31 pediatric cases of recurrent respiratory papillomatosis were identified. The only significant factor associated with severe forms of recurrent respiratory papillomatosis was the maternal history of condylomas during pregnancy (OR: 12.05 [P = 0.05]). The analysis failed to identify risk factors that could be used clinically to identify recurrent respiratory papillomatosis cases likely to take a severe course. Although too early to determine, vaccination against the HPV types involved most commonly in recurrent respiratory papillomatosis may provide the best hope to prevent severe forms of this disease. J.
