RESUMO
OBJECTIVES: Studies suggest that transplant patients are at a higher risk of developing chronic rhinosinusitis (CRS). However, there is a dearth of studies describing the factors that may be linked to the development of CRS in this population. Our objective is to identify the risk factors associated with the development of CRS in transplant recipients. STUDY DESIGN: Retrospective cohort. SETTING: Tertiary care center. METHODS: This cohort included 3347 transplant recipients seen between 2017 and 2022. Of these, 2128 patients met the inclusion criteria and were grouped according to whether they were diagnosed with CRS during the post-transplant period. The analysis included both univariate and multivariate analysis to ascertain the odds ratio (OR) and predictive factors. RESULTS: Of the 2128 patients, 649/2128 (30.4%) had CRS. CRS patients had an increased prevalence of previous endoscopic sinus surgery, allergic rhinitis, and recurrent acute rhinosinusitis in the pre-transplant period compared to the non-CRS group. According to the multivariate analysis, patients with primary immunodeficiency and additional transplant were 1.9 and 3.1 times more likely to develop CRS during the posttransplant period (95% CI: 1.3-2.6, p < .0001), (95% CI: 1.3 -7.3, p = .01), respectively. Sirolimus use was also associated with the development of CRS (OR = 1.4, 95% CI: 1.1-1.9, p = .01). CONCLUSION: This study is the largest cohort aimed at determining the predictive factors associated with the development of CRS. Patients with pretransplant rhinologic conditions, hematologic deficiencies, and the utilization of specific immunosuppressants were found to have a higher likelihood of developing CRS following transplantation.
RESUMO
KEY POINTS: The study found a higher incidence of chronic rhinosinusitis (CRS) and recalcitrant CRS in cadaveric organ transplant recipients compared to those receiving living donor transplants. Recipients of cadaveric transplants were 1.32 times more likely to develop CRS and 1.68 times more likely to develop medically recalcitrant CRS. Living kidney transplants significantly reduced the risk of developing CRS (OR = 0.12) and recalcitrant CRS (OR = 0.11), highlighting a potentially protective effect against these conditions. In contrast, cadaveric liver transplants were associated with an increased risk of CRS and medically recalcitrant CRS. Kaplan-Meier survival analysis indicated a significant difference in time to CRS onset between cadaveric and living donor transplants. Median time to CRS onset was longer for living donor recipients (21.1 months) compared to cadaveric recipients (15.6 months). This study underscores the need for transplant teams and otolaryngologist to consider donor type during transplant follow-up due to differing risks of CRS development.
RESUMO
Objective: Cartilaginous tumors of the larynx are rare, representing less than 1% of all laryngeal tumors. Chondromas are benign mesenchymal tumors characterized by a slow-paced growth, primarily originated in the cricoid cartilage, followed by the thyroid, arytenoid, and epiglottic cartilages. This scoping review aims to understand the extent of evidence on the epidemiology, clinical characteristics, morbidity, and recurrence of the laryngeal chondroma (LC). Data sources: MEDLINE (Ovid), Embase (Elsevier), Web of Science (Clarivate), Cochrane Central Register of Controlled Trials and Systematic Reviews, Lilacs, Scopus, and Google Scholar databases. Review methods: The scoping review was conducted from 1816 to 2023, for observational studies describing LC. Titles and abstracts were screened for relevance, followed by an evaluation of the full text for eligibility. The data were collected from the qualifying articles, and a narrative summary of the outcomes was prepared. Results: One hundred and nineteen studies met the inclusion criteria. Ninety-four case reports, 22 case series, and 3 cohorts. Two hundred and four participants with a diagnosis of LC were described. Male:female ratio was 2.8:1. The most common localization was the cricoid (113; 47.08%), followed by the thyroid (45; 18.75%), and the arytenoid cartilage (27; 11.25%). Dyspnea (78.85%) and hoarseness (74.28%) were the most reported symptoms. The recurrence rate was 11.25%, and complications were uncommon following the resection. Conclusion: This scoping review found a low-frequency rate over all the cartilaginous laryngeal tumors. Most patients were treated with resection, with a low rate of malignancy conversion. This population has low attributable mortality, morbidity, and recurrence according to the current literature.
