Project description:Recurrent respiratory papillomatosis (RRP) is a rare disease caused by human papillomavirus. Aggressive forms of RRP require repeated cytoreductive surgery to restore airway patency. Tracheal disease is even less common and lung parenchyma is involved in less than 1% of patients. We present reports of three cases of RRP with progressive lung disease in adult patients.

Project description:ObjectiveDespite recent advancement recurrent respiratory papillomatosis (RRP) remains a rare but challenging benign airway neoplasm. In recent years there has been significant shifts in incidence of this disease due to changes in vaccination and prevention for human papilloma virus (HPV) and its related pathology. This review will highlight the epidemiology, prevention and treatment of RRP.MethodsThe PubMed database was searched using relevant MeSH terms including "recurrent respiratory papillomatosis." The titles and abstracts were reviewed to assess relevance and unrelated articles were excluded. A full-text review for select articles was performed, the data and discussions were interpreted and synthesized to create a concise update on the management of RRP.ResultsWith the increasing utilization of the 9-valent and quadrivalent HPV vaccine in Australia, we have seen a significant decrease in the incidence of RRP. Preliminary data in the US shows a similar trend of decreased incidence after implementation of vaccination. Single dose Gardasil in developing countries has shown sustained immunization for at least 7 years. Preliminary clinical trials and retrospective studies have shown the HPV vaccine may have benefit as a treatment method in addition to prevention for HPV related diseases. Bevacizumab (Avastin), a VEGF monoclonal antibody, has shown promise as a systemic treatment for RRP. The Corona Virus Disease 2019 (COVID-19) pandemic has affected perioperative management of RRP.ConclusionRRP continues to decline in incidence since the implementation of HPV vaccination. Advancement in the medical management including Bevacizumab show promise as an additional option for the management of RRP.

Project description:BackgroundImmune checkpoint blockade can provide clinical benefit for patients with advanced cancer. Here, we report durable disease control over many years following PD-L1 blockade through induction of a viral antigen-specific T cell response in an adult patient with recurrent respiratory papillomatosis.MethodsAntigen-specific T cell response assays, single cell RNA-sequencing, and RNA-scope was used to study clinical tissues.ResultsAn HPV6 E2-specific T cell clone restricted to HLA-B*55, present at low frequency in the pre-treatment papilloma, significantly expanded after six doses of PD-L1 blockade and remained present and functional at the site of initial response in the larynx as a tissue resident memory T cell for 4 years. An associated reduction in E2 target gene was observed following treatment.ConclusionsAlthough demonstrated in a single exceptional responder, these results highlight that immune checkpoint blockade may induce durable, viral antigen-specific immunity of sufficient magnitude to control disease in patients with nonmalignant disorders.

Project description:ObjectivesRecurrent respiratory papillomatosis (RRP) is a chronic disease of the respiratory tract that occurs in both children and adults. It is caused by the human papillomavirus (HPV), in particular low-risk HPV6 and HPV11, and aggressiveness varies among patients. RRP remains a chronic disease that is difficult to manage. This review provides perspectives on current and future management of RRP.ResultsThe current standard of care is surgical excision, with adjuvant therapies as needed. Surgical management of RRP has evolved with the introduction of microdebriders and photoangiolytic lasers; the latter can now be used in the office setting. Numerous adjuvant pharmacologic therapies have been utilized with some success. Also, exciting preliminary data show that HPV vaccines may prolong the time to recurrence in the RRP population. There is also optimism that wide-spread HPV vaccination could reduce RRP incidence indirectly by preventing vertical HPV transmission to newborns.ConclusionTo date, the biology of RRP is not well understood, although it has been noted to become more aggressive in the setting of immune suppression. Additional research is needed to better understand immune system dysfunction in RRP such that immunomodulatory approaches may be developed for RRP management.Level of evidence4.

Project description:Recurrent respiratory papillomas (RRP) are benign airway tumors, caused primarily by human papillomaviruses (HPV) types 6 and 11. The disease is characterized by multiple recurrences after surgical removal, with limited effective therapy. To identify novel targets for future therapy, we established transcriptional profiles for actively growing papillomas compared with autologous, clinically normal, laryngeal epithelia (adjacent tissue). Total ribonucleic acid (RNA) from 12 papillomas and 12 adjacent tissues were analyzed by microarray, and the matched sets of tissues compared by paired t test, to identify differentially expressed genes in papilloma tissues while minimizing variations intrinsic to individual patients. Quantitative polymerase chain reaction (PCR) was used to confirm the relative expression levels for a subset of genes. Within the 109 differentially expressed transcripts whose expression varied at least three-fold were two large groups of genes with related functions. The first group consisted of 18 genes related to host defense, including both innate and adaptive immunity. The second group contained 37 genes that likely contribute to growth of papillomas as benign tumors, since the altered pattern of expression also had been reported previously in many cancers. Our results support our previous studies that document a systemic T(H)2-like adaptive immune response in RRP, and suggest that there is a role for altered innate immunity in RRP as well. We propose that HPV 6 and 11 infection establishes a tumorigenic microenvironment characterized by alteration of both innate inflammatory signals and adaptive immune responses that prevent effective T(H)1-like response, in conjunction with altered expression of numerous genes that regulate cellular growth and differentiation.

Project description:Whether humoral immunity plays a role in HPV type 6 or 11 virus-mediated Juvenile-onset Recurrent Respiratory Papillomatosis (JORRP) remains unknown. In the present study, serum total IgG level in 44 JORRP patients was significantly decreased compared with that in 40 healthy controls. Moreover, expanded CD3-CD19+ B cells with down-regulation of CD23, CD40, HLA-DR and up-regulation of CD86 expression were found in the peripheral blood of JORRP patients. Flow cytometry analysis of B-cell compartment showed that the frequency of both CD19+CD27hi plasma cells and CD19+CD27+ memory B cells were decreased in JORRP patients. Importantly, although the proportion of circulating CXCR5+PD1hi Tfh cells was not changed, the function of Tfh cells were greatly impaired with reduced ability of IL-21 secretion to promote B cell maturation. Association analysis by the Kaplan-Meier method revealed that IL-21 secreting Tfh cell was positively correlated to the CD27+ B cell subset frequency, the serum IgG level and the frequency of recurrence in JORRP patients, but negatively correlated to the percentage of IgD+CD27- B cell. We concluded that a reduced IL-21 secretion by Tfh cells may limit B cell maturation and antibody production in JORRP patients and Tfh cell-derived IL-21 might be associated with JORRP outcome in clinic.

Project description:Recurrent respiratory papillomatosis (RRP) is a non-malignant disease, characterized by the production of wart-like growths in the respiratory tract, affecting both young people and adults (juvenile-onset recurrent respiratory papillomatosis, JORRP, and adult-onset recurrent respiratory papillomatosis, AORRP, respectively). Infection caused by human papillomavirus (HPV) is known as the main factor involved in RRP development. Complications of RRP may rarely occur, including lung involvement and malignant transformation. The present systematic review aimed to evaluate the prevalence of severe complications, such as lung involvement and lung tumor in JORRP and AORRP patients, and assess the role of HPV genotypes in the progression of disease severity following the guideline for reporting systematic reviews and meta-analysis (PRISMA Statement). A total of 378 studies were found on PubMed and Scopus using the following MESH terms: "recurrent respiratory papillomatosis and lung tumor" and "pulmonary tumor and recurrent respiratory papillomatosis". Basing on inclusion and exclusion criteria, a total of 11 studies were included in the systematic review. We found a pooled prevalence of 8% (95% CI: 4-14%; I2: 87.5%) for lung involvement in RRP patients. In addition, we found a pooled risk difference of 5% in lung involvement between JORRP and AORRP (95% CI: -7-18%; I2: 85.6%, p-value: 0.41). Among patients with lung involvement, we observed a pooled prevalence of lung tumor of 4% (95% CI:1-7%; I2: 67.1%) and a pooled prevalence mortality for this group of 4% (95% CI:2-6%; I2: 0%). Overall, the positivity rate for HPV-6 and -11 in patients with RRP was 91%. Considering only cases with pulmonary involvement, the pooled prevalence for HPV-11 was 21% (95% CI: 5-45%; I2: 77.2%). Our results evidenced a low/middle risk of pulmonary involvement and lung tumor in JORRP and AORRP patients, with an increased risk for HPV-11-positive patients. Further studies should be performed to improve knowledge and adopt preventive measures to contrast the progression to severe diseases in RRP patients.

Project description:Recurrent respiratory papillomatosis (RRP) is characterised by multiple laryngeal papillomas. Left untreated, the lesions enlarge, spread, and endanger the airway. Medical treatments are unsatisfactory, and repeated surgery remains the mainstay of therapy. RRP is caused by human papillomavirus (HPV) infection. However, since oral HPV infection is common and RRP is rare, other host and/or viral factors may contribute to pathogenesis. In an attempt to identify such factors, we have investigated 60 patients. The patients were HLA class I, II, and tumor necrosis factor TNF typed by sequence-specific primer PCR, and the results compared to those for 554 healthy controls by using Fisher's exact test. Peripheral blood mononuclear cell proliferative responses of 25 controls and 10 patients to HPV-11 L1 virus-like particles (VLP) were compared. Short-term VLP-specific T-cell lines were established, and recognition of L1 was analyzed. Finally, the L1 open reading frames of HPV isolates from four patients were sequenced. Susceptibility to RRP was associated with HLA DRB1*0301 (33 of 60 patients versus 136 of 554 controls, P < 0.0001). The three most severely affected patients were homozygous for this allele. A range of T-cell proliferative responses to HPV-11 VLP were observed in DRB1*0301-positive healthy donors which were comparable to those in DRB1*0301-negative controls. Individuals with juvenile-onset RRP also mounted a range of VLP responses, and their magnitude was negatively correlated with the clinical staging score (P = 0.012 by the Spearman rank correlation). DRB1*0301-positive patients who responded to L1 recognized the same epitope as did matched controls and produced similar cytokines. Sequencing of clinical isolates excluded the possibility that nonresponsiveness was the result of mutation(s) in L1.
