Summary

Objective

Recurrent respiratory papillomatosis (RRP) is the most common benign neoplasm affecting the larynx and upper respiratory tract. The aim of our study was to investigate whether children and partners of patients with RRP develop the same disease and to determine whether there is an impact of pregnancy on the course of RRP.

Patients and methods

Thirty-eight of 42 patients with RRP were accepted for a multicenter prospective study in Germany in 21.06.83–12.03.90. Mean follow-up duration was 15.3 ± 1.8 years. The data of partners of patients with RRP was collected during the period of observation and then updated via interviews in January 2006. Twenty-nine children and four grandchildren were born to 14 patients with RRP. Fifteen of 448 cases of patients with RRP were treated in Saint Vladimir Moscow Children's Hospital in Russia in 1988–2003 and analyzed retrospectively. Sixteen children and one grandchild were born to 15 patients with RRP from Russia. In both studies, the virus type of patients with RRP was identified by nested PCR or Southern blot hybridization. Statistical analysis was perfomed using Fisher's exact test (probability value set at p < 0.05).

Results

All children born to patients with RRP were healthy. RRP was not diagnosed in any of them on the basis of clinical or histological examination. Four of 45 children developed dysphonia, two of them had vocal cord nodules. None of the sexual partners of patients has developed RRP during the follow-up period. Pregnancy was accompanied by excessive growth of papillomas in all women (100 % ) with RRP associated with HPV type 11, and only in 16.7 % of women with RRP associated with HPV type 6 (p = 0.001).

Conclusions

Patients with RRP are able to have healthy children regardless of the stage of the disease. Partners of RRP patients do not develop RRP during an observation period of 15 years. Pregnancy has a negative impact on the course of RRP and local laryngeal status in patients; it is more significant in HPV type 11 associated cases as it is manifested by more rapid papillomas growth and more frequent recurrence.
