OBJECTIVES: Recurrent respiratory papillomatosis (RRP) is a rare disease, but one with severe morbidity and occasional mortality. The aetiological agent is human papillomavirus (HPV), and HPV types 6 and 11 account for over 90% of all cases. In the active phase of the disease, patients require multiple hospital admissions for surgical removal or ablation of these benign tumors, which are likely to obstruct the airways if left unchecked. Long-term sequelae include scarring of the vocal cords, change in voice timbre, or even muteness if a tracheostomy is required...

OBJECTIVE: Although it has been shown that prophylactic vaccination can induce genital immunity, there is inadequate information on human papillomavirus (HPV) vaccine-induced oral immunity, which is of particular interest due to HPV-associated oropharyngeal malignancies and recurrent respiratory papillomatosis. Therefore, we assessed the efficacy of various HPV vaccines against oral HPV pseudovirus (PsV) infection in mice. STUDY DESIGN: Preclinical scientific investigation...

BACKGROUND: Defects in the adaptive immune response to human papillomavirus-6 and -11 are among the most important mechanisms for Juvenile-onset Recurrent Respiratory Papillomatosis (JORRP) development. However, the percentage of CD8+ T cells and peripheral TH1/TH2 immune responses in Juvenile-onset recurrent respiratory papillomatosis is still not well addressed due to limited sample sizes. METHODS: Twenty-three patients who were diagnosed with JORRP and underwent surgical intervention at the Beijing TongRen Hospital from October 2015 to March 2016 were enrolled in our study...

OBJECTIVES: Recurrent respiratory papillomatosis (RRP) is a relatively rare, chronic disease caused by Human Papilloma Virus (HPV) 6 and 11, and characterized by wart-like lesions in the airway affecting voice and respiratory function. The majority of HPV infections are asymptomatic and resolve spontaneously, however, some individuals are afflicted with persistent HPV infections. Failure to eliminate HPV 6 and 11 due to a defect immune responsiveness to these specific genotypes is proposed to play a major role in the development of RRP...

BACKGROUND Recurrent respiratory papillomatosis (RRP), caused by human papillomavirus (HPV), is the most common benign neoplasm of the larynx and central airways. RRP has a significant impact on quality life and high annual costs to healthcare. Currently, there is no cure for RRP, leading to repeated debulking operations for symptomatic palliation. Various local adjuvant therapies have also been studied with mixed efficacy. HPV oncogene products increase expression of vascular endothelial growth factor (VEGF) providing a potential target for treatment of RRP...

Genetic variability related to the host immune system has been proposed as one of the most influential factors in the development of diseases caused by HPV. CLINICAL CASE: We report the case of a 5-year-old child in whom chronic laryngeal papillomatosis, probably acquired vertically during labor, was detected. The diagnosis of laryngeal papillomatosis was confirmed with a biopsy after a first surgery to remove the papillomas. The Derkay classification system was used to assess the severity of papillomatosis...

Solitary papilloma is a human papillomavirus (HPV)-induced benign indolent epithelial tumor with limited growth, whereas papillomatosis is an entirely different entity. Papillomatosis requires attention because of its aggressive and recurrent clinical progress with risks of dysplastic and malignant transformation. Recurrent respiratory papillomatosis (RRP) has a high prevalence of dysplasia and reports of transformation to carcinoma-ex-papillomatosis, especially when associated with low-risk HPV type 11. Although papillomatosis seldom occurs in the oral cavity, this report describes 3 cases of oral papillomatosis in immunocompromised patients, with 1 case identified as having HPV type 11...

INTRODUCTION: Tumor immunotherapy have broadened therapeutic options for tumor treatment. The role of immune function in juvenile recurrent respiratory papillomatosis (JRRP) has not been investigated. Applying immunoblockade inhibitors as a novel disease treatment is unclear. Our study, for the first time, evaluates immune infiltration and immuno-suppressive molecule expression in JRRP. Our study provides insights in possibly treating this disease with tumor immunotherapies. We aimed to determine expression of programmed death-ligand 1 (PD-L1), a cancer escape protein, and presence of CD8+ T cell infiltration in tumor microenvironment...

INTRODUCTION: The relationship between human papilloma virus (HPV) and upper respiratory tract pathology was better understood in recent years and represents now an issue of particular interest in carcinogenesis and in immunocompromised host. We describe a case in which a rare genotype HPV-related papillomatosis mimics laryngeal carcinoma in an immunocompromised host. METHODS: A 54-year-old woman with a history of HIV-HCV coinfection and anal and laryngeal cancer successfully treated some years before was hospitalized for severe dyspnea, cough and dysphagia...

Recurrent respiratory papillomatosis (RRP) is a disease of the respiratory tract caused by infection with the human papillomavirus (HPV) and is characterized by multiple recurring papillomas throughout the respiratory tract. Although rare, extra laryngeal involvement carries the risk of malignant transformation in 3-7% of adults. We report the case of a patient with unmonitored juvenile onset RRP with pulmonary involvement found to have malignant transformation to squamous cell carcinoma (SCC). Incidentally found on chest radiography for mild chest wall trauma, she was found to have a large left lower lobe mass with pathology consistent with SCC...

Recurrent respiratory papillomatosis (RRP) is a benign disease of the upper aero-digestive tract caused by human papillomavirus (HPV) infection, which affects children and young adults. The aim of this review is to describe the main etiological, epidemiological, clinical, diagnostic, and treatment aspects of RRP. Most infections in children occur at birth, during passage through the birth canals of contaminated mothers. In adults, HPV is transmitted sexually. Papillomas usually appear as exophytic nodules, primarily in the larynx, but occasionally involving the nasopharynx, tracheobronchial tree, and pulmonary parenchyma...

BACKGROUND: FoxP3 is the most dependable marker for regulatory T cells which play a major role in immune tolerance. Foxp3 gene polymorphisms were associated with various autoimmune diseases and clearance of viral infections. We studied the association of Foxp3 polymorphisms in severe RRP patients. METHODS: A total of 30 Korean severe RRP patients and 195 healthy controls were enrolled. Foxp3 polymorphisms (rs5902434 del/ATT, rs3761548 C/A, rs3761549 C/T, and rs2232365 G/A) were determined by PCR and sequencing...
