title: Pediatric respiratory papillomatosis: prognostic role of viral typing and cofactors.
abstract: Children with recurrent respiratory papillomatosis vary greatly in their clinical disease course. Many have mild disease with eventual remission while others present with an early aggressive airway obstructive course. This study consisted of 24 pediatric patients whose specimens underwent polymerase chain reaction analysis for cytomegalovirus (CMV), herpes simplex virus (HSV), and human papillomavirus (HPV) type. Nineteen of 24 specimens contained enough DNA for this study. None of the specimens were found to contain DNA from HPV-16, -18, -31, -33; CMV; or HSV, which contrasts with our previous findings in adults. Ten patients were infected by HPV-11 and seven of these underwent tracheotomy because of an aggressive tumorigenic clinical course. Nine patients were infected by HPV-6 alone of whom only two required a tracheotomy (P = 0.05, Fisher's Exact Test). The early airway obstructive course associated with HPV-11, however, had no bearing on achieving eventual disease remission, with decannulation achieved in eight of nine children.
