O uso do cidofovir para papilomatose respiratória recorrente juvenil (PRRJ) ainda não tem estudos caso-controle suficientes que comprovem sua eficácia em literatura. OBJETIVO: Avaliar fatores que influenciem o prognóstico da PRRJ, e observar a atuação do cidofovir na erradicação da PRRJ. DESENHO DO ESTUDO: Retrospectivo. MATERIAIS E MÉTODOS: 22 crianças com PRRJ foram avaliadas num centro terciário. Todas as crianças foram submetidas ao tratamento cirúrgico, seguido (Grupo 2) ou não (Grupo 1) pelo uso do cidofovir. A idade ao diagnóstico foi correlacionada ao escore de Derkay e à evolução da doença. Os Grupos 1 e 2 tiveram suas evoluções comparadas entre si. RESULTADOS: Quinze crianças foram consideradas curadas, 8 no Grupo 2 e 7 no Grupo 1. Houve uma correlação negativa entre idade e Escores Total e Clínico (PThe efficacy of cidofovir in juvenile recurrent respiratory papillomatosis (JRRP) remains uncertain due to the lack of published case-control studies. AIM: To establish factors affecting the progression of JRRP prognosis, and to evaluate cidofovir for eradicating JRRP. STUDY DESIGN: Retrospective. METHODS: 22 children with JRRP were evaluated at a referral center. All children underwent surgical debulking, followed by cidofovir injection (Group 2) or not (Group 1). Age at diagnosis was correlated with the Derkay score and disease outcome. Disease progression was compared between groups 1 and 2. RESULTS: fifteen children were considered disease-free; 8 were in Group 2 and 7 in Group 1. Age and total and clinical scores (P<0.05) were negatively correlated. The mean number of surgeries required to control the disease was identical in both groups; the duration of treatment until remission was significantly higher in Group 1 (P<0,05). CONCLUSION: JRRP is more aggressive in earlier onset disease. The duration of treatment was significantly lower in patients treated with cidofovir until eradication of JRRP compared to patients treated with surgery only.
