Abstract

The aim of the study was to assess the clinical efficiency of quadrivalent HPV (types 6/11/16/18) vaccine in patients with recurrent respiratory papillomatosis (RRP). This was a prospective study of patients with RRP treated from January 2009 to July 2012 at the Ear, Nose and Throat Department of the Emergency County Hospital of Cluj-Napoca, Romania. Demographic characteristics, onset of RRP, HPV typing, use and number of cidofovir injections, number of surgeries for RRP per year, and use of human papillomavirus vaccine (types 6, 11, 16, 18) (recombinant, adsorbed)/Silgard® were considered from all the patients included in the study. Charts were reviewed for follow-up after diagnosis, after cidofovir, and after Silgard; all the statistical tests were applied at a significance level of 5 %. The recurrences were observed within 27.53 ± 11.24 days after intralesional cidofovir injection. Thirteen patients with recurrence after cidofovir agreed and received Silgard® vaccine. 85 % [54.44–99.41] of patients had no recurrences during 1-year follow-up. The recurrence of papillomas was observed in two patients (15 %, 95 % CI [0.59–45.56]), one with adult-onset RRP and one with juvenile-onset RRP. Both recurrences appeared after the first Silgard dose; one month after the third vaccine dose each patient underwent a new surgery for remaining papillomas with no recurrences at 1-year follow-up visit. Silgard® vaccination had a good effect and proved to be efficient in the treatment of our patients with RRR without appearance of recurrence in 85 % of the patients during 1-year follow-up.
