Recurrent respiratory papillomatosis in children caused by HPV 6,11 can be a life threatening condition resulting in surgical interventions. The maturing and disintegrating papillomas are the sources for the subsequent HPV relapses and immunization might slow down or even prevent this ongoing process.
After an initial immunological and ear-nose-throat (ENT) assessment children with at least 3 relapses in their patient history will be vaccinated with 4-valent HPV vaccine according to the following schedule: 0., 2., 6. months. It will be followed by an immunological and 3 ENT examinations to assess response to vaccination.
|Condition or disease||Intervention/treatment||Phase|
|Recurrent Respiratory Papillomatosis||Biological: 4-valent HPV vaccine||Phase 3|
- ear-nose-throat (ENT) examination + oesophagoscopy
- assessment of selected humoral (antibodies) and
- cellular immune response parameters(INF gamma and granzyme B testing)
- in vitro and in vivo stimulation of PMBCs with the HPV-4 vaccine
- Immunization with 4-valent HPV vaccine at 0,2,6 months
- 1 month after 3rd vaccine dose - immunological assessment (same tests as in the enrollment phase)
- 6, 12 and 18 months after the 3rd vaccine dose - ENT + oesophagoscopy
