Use of Interferon-Alpha in Recurrent Respiratory Papillomatosis: 20-Year Follow-up
2005
Objectives: The aim of this study was analysis of the results of use of interferon-α (IFN-α) in patients with recurrent respiratory papillomatosis (RRP) and correlation of the results with human papillomavirus (HPV) type. Methods: A multicenter prospective series (42 patients from 22 hospitals) yielded 20 years of follow-up of patients with RRP and HPV typing who were treated with IFN-α in doses of 3 MU/m2 3 times per week. Results: During long-term follow-up (mean ± SD, 172 ± 36.8 months), the rate of event-free survival evaluated by Kaplan-Meier analysis was 42.8%, and the overall survival rate was 82.6%. The HPV typing revealed an association of HPV 11 with a more aggressive disease cour…
Vaccination against HPV-Associated Neoplasias
2014
Neoplasias associated with anogenital human papilloma viruses (HPV) are characterised by high patient morbidity and mortality and by appreciable limitations in the patientʼs quality of life. Each year 530,000 women worldwide and 4800 women in Germany develop cervical cancer 1, 2. Biomolecular and epidemiological studies carried out in the past 25 years have demonstrated causal link between persisting infections with HPV 16 and HPV 18 and at least 11 other so-called high-risk HPVs (HR-HPVs) and the development of cervical cancer and its precursor lesions (so-called dysplasias or, respectively, cervical intraepithelial neoplasias – CIN). HPV 16, HPV 18 and other HR-HPVs are also the causes of…
Human papilloma virus (HPV)-associated gynecological alteration in mothers of children with recurrent respiratory papillomatosis during long-term obs…

Abstract Background : Human papilloma virus (HPV) is one of the most frequently observed sexually transmitted infections. The study' purpose was to investigate the relation between a mother's gynecological history and the local status of her child with recurrent respiratory papillomatosis (RRP). Methods : Forty-two patients enrolled in a prospective multicenter study between 1983 and 1990. The study included patients with juvenile-onset and adult-onset RRP. All patients underwent surgery and treatment with α-interferon. Thirty-eight patients were followed up until 31.01.2006. Twenty-five mothers of these patients participated in a parallel prospective study of genital HPV infection. In 1989…
Distribution and density of CD1a+ and CD83+ dendritic cells in HPV-associated laryngeal papillomas.
2009
Summary Background Respiratory papillomatosis associated with human papilloma virus (HPV) infection is the most common benign laryngeal neoplasm. The age of patients at disease onset, HPV type, number of surgeries are well known prognostic factors of the disease course. The correlation between dendritic cell (DC) density in tumor tissue and clinical prognosis was established. Aim The aim of our study was to estimate the density of DC in laryngeal papillomas associated with HPV types 6/11 infection and to evaluate the relationship between the number of DC and the disease severity. Materials and methods Our study included 40 randomly selected biopsy specimens from patients with HPV-positive l…
Children and partners of patients with recurrent respiratory papillomatosis have no evidence of the disease during long-term observation.
2006
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 gra…
