ABSTRACT

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

ABSTRACT

PURPOSE: The role of systemic sensitization in the pathophysiology of chronic rhinosinusitis with nasal polyps (CRSwNP) remains elusive. This study sought to characterize the pattern of cytokines in polyp tissues from atopic and nonatopic patients with CRSwNP. METHODS: Atopic and nonatopic polyp and normal tissues were collected from 70 CRSwNP patients and 26 control subjects, respectively. The distribution of inflammatory cells (eosinophils, neutrophils, mast cells, etc.) were examined using immunohistochemistry, the mRNA levels of the transcription factors GATA-3, T-bet, RORc, and FOXP3 were determined using quantitative real-time polymerase chain reaction. The levels of inflammatory mediators (IFN-gamma, IL-5, IL-17A, etc.) in tissue homogenates were measured using enzyme-linked immunosorbent assay (ELISA). Moreover, the levels of inflammatory mediators in the supernatant of anti-IgE stimulated polyp tissues were measured using ELISA. RESULTS: Atopic CRSwNP patients were characterized by increased eosinophil accumulation, enhanced eosinophilic inflammation (elevated IL-5, ECP, and total IgE), and significantly increased GATA-3 mRNA levels (P<0.05), whereas both atopic and non-atopic CRSwNP patients showed decreased FOXP3 mRNA expression (P<0.05). After addition of anti-IgE stimulation, atopic CRSwNP patients produced more IL-5, IL-2, IL-10, IL-17A, and PGD2 in the supernatant of stimulated polyp tissues than nonatopic CRSwNP patients did. CONCLUSIONS: Atopic and nonatopic CRSwNP patients may possess the patterns of inflammatory response in polyp tissues.

ABSTRACT

Objective:To observe the expression of interleukin-17 and the infiltration of eosinophilic cells in nasal polyps and allergic rhinitis, and investigate the roles of IL-17 and eosinophils in the etiology of nasal polyps and allergic rhinitis.Method:A study was conducted on 21 patients of nasal polyps, 18 ones of allergic rhinitis and 12 normal individuals. Immunohistochemical stain with the rabbit monoclonal antibodies of IL-17 was carried out.The eosinophilic cells infiltrated in different tissues were stained with HE, then counted under high power filed.The data was analyzed with ANOVA of SPSS12.0 software.Result:Many IL-17 stained cells were found in the samples of nasal polyps and allergic rhinitis, which were significantly higher than those in normal individuals(P<0.05). Positive cell number in tissues of allergic rhinitis was similar to that in nasal polyps, but higher than in normal individuals. As for HE staining, there was no significant deviation of numbers of eosinophilic cell in tissue between allergic rhinitis and nasal polyps,while which differed from the normal ones(P<0.05).Conclusions:①IL-17 is a newly cytokine which expressed in mucosa of allergic rhinitis and nasal polyps tissue. It indicates the degree of immunological reaction and inflammatory reaction, and can be used as an index to research the mechanism of nasal polyps as well as allergic rhinitis.②The eosinophilic cells count was correlated with the amount of IL-17 positive cells in nasal ployps and with allergic rhinitis correlation coefficients were R=0.606(P<0.01)and R=0.446(P<0.05) respectively . It seems that eosinophils, which are regulated by IL-17, play an important roles in the development of nasal polyps and allergic rhinitis.
