Liu Y, Kong Y, Zhou X. Screening and analysis for potential clinical diagnostic and prognostic markers in allergic rhinitis. Am J Transl Res 2024; 16:2670-2682. [PMID: 39006280 PMCID: PMC11236636 DOI: 10.62347/gkze5945] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Accepted: 05/30/2024] [Indexed: 07/16/2024]
Abstract
PURPOSE To identify potential clinical diagnostic and prognostic markers for allergic rhinitis (AR) by analyzing a range of inflammatory and clinical markers in a cohort of patients. METHODS We conducted a retrospective analysis of clinical data from 493 AR patients treated at Qianjiang Central Hospital from January to March 2023. Patients were categorized based on their outcome. Inclusion and exclusion criteria were strictly applied to select the study population. Various clinical and inflammatory markers were assessed, and statistical analyses were performed to evaluate their diagnostic and prognostic utility. RESULTS No significant differences in traditional demographic factors were found between the good and poor prognosis groups (all P > 0.05). However, significant differences were observed in several inflammatory and clinical markers: Interleukin-4 (IL-4) levels were 17.32 ± 4.21 pg/mL in the good prognosis group versus 18.56 ± 5.89 pg/mL in the poor prognosis group (t=2.562, P=0.011). Interleukin-5 (IL-5) levels were 15.65 ± 3.78 pg/mL versus 16.52 ± 4.56 pg/mL, respectively (t=2.221, P=0.027). Transforming growth factor-β1 (TGF-β1) levels were 39.16 ± 8.92 pg/mL versus 41.32 ± 9.67 pg/mL (t=2.513, P=0.012), and histamine levels were 11.87 ± 3.21 ng/mL versus 12.56 ± 4.03 ng/mL (t=1.991, P=0.047). Interleukin-13 (IL-13) levels were 16.32 ± 3.56 pg/mL versus 17.09 ± 4.21 pg/mL (t=2.108, P=0.036). Serum immunoglobulin E (IgE) levels were significantly different, with 164.87 ± 45.32 IU/mL in the good prognosis group compared to 198.56 ± 58.21 IU/mL in the poor prognosis group (t=6.866, P < 0.001). The composite biomarker model demonstrated high predictive value for AR prognosis with an Area Under Curve of 0.906. Individual markers such as TGF-β1, IL-13, and serum IgE levels showed strong diagnostic potential. CONCLUSION Our findings underscore the clinical utility of various inflammatory and clinical markers as diagnostic and prognostic indicators for AR. TGF-β1, IL-13, and serum IgE levels, in particular, demonstrated significant diagnostic and prognostic value. An integrated approach combining multiple biomarkers could enhance the accuracy of AR diagnosis and prognosis. Further validation through prospective clinical studies and consideration of treatment interventions are recommended to clarify the clinical implications of these markers.

Abstract
BACKGROUND This study examined the knowledge, attitude, and practice (KAP) toward allergic rhinitis (AR) among parents. METHODS This cross-sectional study enrolled parents of children with AR at Ningbo Hangzhou Bay Hospital between December 2022 and March 2023. A self-administered questionnaire was developed to collect the demographic characteristics, knowledge, attitudes, and practices toward AR. RESULTS This study included 480 questionnaires, and 78.33% were mothers. The mean knowledge, attitude, and practice scores were 13.49 ± 6.62 (possible range: 0-24), 33.99 ± 3.40 (possible range: 8-40), and 21.52 ± 3.36 (possible range: 5-26), indicating poor knowledge, positive attitudes, and proactive practice. Multivariable logistic regression analysis showed living in urban areas in Ningbo outside Hangzhou Bay New Zone (OR = 4.33, 95%CI: 1.52-12.34, P = 0.006), living in rural areas in Ningbo (OR = 2.15, 95%CI: 1.00-4.59, P = 0.049), being self-employed (OR = 1.99, 95%CI: 1.00-3.95, P = 0.049), monthly income per capita ≥ 20,000 CNY (OR = 1.89, 95%CI: 1.02-3.47, P = 0.042), child with one biological sibling (OR = 0.48, 95%CI: 0.30-0.78, P = 0.003), and ≥ 6 times hospital visits for AR (OR = 2.32, 95%CI: 1.40-3.86, P = 0.001) were independently associated with adequate knowledge. The knowledge (OR = 1.09, 95%CI: 1.05-1.13, P < 0.001) and ≥ 6 times hospital visits for AR (OR = 1.84, 95%CI: 1.06-3.22, P = 0.032) were independently associated with a positive attitude. The knowledge (OR = 1.08, 95%CI: 1.04-1.13, P = 0.001), attitude (OR = 1.41, 95%CI: 1.28-1.55, P < 0.001), monthly income per capita ≥ 20,000 CNY (OR = 3.59, 95%CI: 1.49-8.65, P = 0.004), no previous hospital visit for AR (OR = 0.35, 95%CI: 0.16-0.78, P = 0.003), and ≥ 6 times hospital visits for AR (OR = 0.40, 95%CI: 0.20-0.81, P = 0.011) were independently associated with the practice scores. CONCLUSIONS The parents of children with AR had poor knowledge but positive attitudes and proactive practice toward AR. This study has identified a need for specific and reliable information initiatives to be introduced as a means of reducing parental concern and ensuring evidence-based strategies for managing children with AR.

Abstract
Background Oral immunotherapy (OIT) is a promising allergen-specific approach in the management of food allergy; however, studies on OIT for allergic rhinitis (AR) have rarely been reported. The purpose of this study is to evaluate the efficacy and safety of OIT using enteric-coated capsules for AR induced by house dust mites. Methods A total of 49 patients with AR were enrolled, including 25 who received subcutaneous immunotherapy (SCIT) and 24 who received OIT. The clinical efficacy and safety in both groups were evaluated. Results After 1 year of treatment, both SCIT and OIT demonstrated significant therapeutic effects. OIT was found to be more effective than SCIT in reducing the total AR symptom score and improving the results of nasal provocation tests. Local and systemic adverse reactions were observed in the SCIT group, while none were reported in the OIT group. Conclusion OIT is an effective and safe treatment for mite-induced AR.

Abstract
BACKGROUND Identifying predictive biomarkers for allergen immunotherapy response is crucial for enhancing clinical efficacy. This study aims to identify such biomarkers in patients with allergic rhinitis (AR) undergoing subcutaneous immunotherapy (SCIT) for house dust mite allergy. METHODS The Tongji (discovery) cohort comprised 72 AR patients who completed 1-year SCIT follow-up. Circulating T and B cell subsets were characterized using multiplexed flow cytometry before SCIT. Serum immunoglobulin levels and combined symptom and medication score (CSMS) were assessed before and after 12-month SCIT. Responders, exhibiting ≥30% CSMS improvement, were identified. The random forest algorithm and logistic regression analysis were used to select biomarkers and establish predictive models for SCIT efficacy in the Tongji cohort, which was validated in another Wisco cohort with 43 AR patients. RESULTS Positive SCIT response correlated with higher baseline CSMS, allergen-specific IgE (sIgE)/total IgE (tIgE) ratio, and frequencies of Type 2 helper T cells, Type 2 follicular helper T (TFH2) cells, and CD23+ nonswitched memory B (BNSM) and switched memory B (BSM) cells, as well as lower follicular regulatory T (TFR) cell frequency and TFR/TFH2 cell ratio. The random forest algorithm identified sIgE/tIgE ratio, TFR/TFH2 cell ratio, and BNSM frequency as the key biomarkers discriminating responders from nonresponders in the Tongji cohort. Logistic regression analysis confirmed the predictive value of a combination model, including sIgE/tIgE ratio, TFR/TFH2 cell ratio, and CD23+ BSM frequency (AUC = 0.899 in Tongji; validated AUC = 0.893 in Wisco). CONCLUSIONS A T- and B-cell signature combination efficiently identified SCIT responders before treatment, enabling personalized approaches for AR patients.

Increased Nasal Blimp1 + Treg Cells After Sublingual Immunotherapy Reflect the Efficacy of Treatment in Allergic Rhinitis. Adv Ther 2024; 41:1698-1710. [PMID: 38443650 DOI: 10.1007/s12325-024-02819-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2024] [Accepted: 02/07/2024] [Indexed: 03/07/2024]
Abstract
INTRODUCTION Allergen-specific immunotherapy (AIT) plays a pivotal role in altering the immune status and tissue responses in allergic rhinitis (AR). This study focuses on the impact of sublingual immunotherapy (SLIT) involving dust mite drops, exploring the modulation of regulatory T cells (Treg) and their specific marker, BLIMP1, in the nasal mucosa. METHODS Immune cells were isolated from nasal lavage fluid of patients with AR undergoing SLIT (n = 94). Treg cells were analyzed for BLIMP1 expression, and chemokine levels associated with Treg recruitment were assessed using Luminex assay. Patients were categorized on the basis of SLIT efficacy and followed for changes after discontinuation. RESULTS SLIT induced a significant increase in nasal Treg cells (7.09 ± 2.59% vs. 0.75 ± 0.27%, P < 0.0001). BLIMP1 expression in Treg cells notably increased after SLIT (0.36 ± 0.22% to 16.86 ± 5.74%, P < 0.0001). Ineffective SLIT cases exhibited lower levels of nasal Treg and Blimp1 + Treg cells (both P < 0.0001). Receiver operating characteristic (ROC) analysis confirmed their potential as efficacy predictors (AUC = 0.908 and 0.968, respectively). SLIT discontinuation led to a significant reduction in Treg and Blimp1 + Treg cells (P < 0.001), emphasizing their maintenance during treatment. Pro-inflammatory cytokines decreased (P < 0.001), while CCL2 associated with Treg recruitment increased (P = 0.0015). CONCLUSION Elevated nasal Blimp1 + Treg cells serve as a predictive biomarker for SLIT responsiveness in pediatric AR. Their influence on immunotherapy effectiveness contributes to a nuanced understanding of SLIT mechanisms, allowing for disease stratification and personalized treatment plans. This study offers scientific support for predicting SLIT efficacy, enhancing the prospects of improved treatment outcomes in AR.

Abstract
OBJECTIVES To investigate the effect of response intensity of allergen skin prick test (SPT) on symptom severity and long-term efficacy of dust mite subcutaneous immunotherapy (SCIT) in allergic rhinitis (AR). METHODS AR Patients diagnosed with dust mite allergy and completed 3 years of SCIT were collected and classified into three groups: grade 2 (SPT of + +), grade 3 (SPT of + + +) and grade 4 (SPT of + + + +). Comparisons between groups were performed to examine the associations of SPT categories and symptom severity and the long-term efficacy of SCIT in AR. RESULTS 181 AR patients were included. There was no significant difference in the baseline TNSS, SMS, RQLQ and VAS, and particularly to symptom severity grading among three SPT grade groups (P > 0.05). The moderate-severe AR was more likely to be smoking and accompany with asthma and had higher prevalence of sensitization to cockroach, mixed grass and tree pollen than mild AR (P < 0.05). Prevalence of sensitization to cockroach, mixed grass, ragweed and animal dander was increased in AR patients with asthma and allergic conjunctivitis (P < 0.05). Furthermore, after 3 years of SCIT, no statistical differences in TNSS, SMS, RQLQ, VAS and long-term efficacy were observed among the three SPT grade groups (P > 0.05). Similarly, long-term outcomes of patients with different SPT grades did not differ among different clinical characteristics and different efficacy determination criteria (P > 0.05). CONCLUSIONS The SPT response intensity cannot be used as an objective evaluation index for symptom severity and the long-term efficacy of SCIT in AR patients.

Abstract
Allergen immunotherapy (AIT) is an etiological treatment strategy that involves administering escalating doses of clinically relevant allergens to desensitize the immune system. It has shown encouraging results in reducing allergy symptoms and enhancing patients' quality of life. In this review, we offer a thorough overview of AIT in China, examining its efficacy, safety, current practices, and prospects. We further underscore the progress made in AIT research and clinical applications, as well as the distinct challenges and opportunities that China faces in this area.

Abstract
PURPOSE OF REVIEW Emerging evidence indicating that the dysfunction of T follicular regulatory (T FR ) cells contributes to excessive immunoglobulin E (IgE) production and the development of allergic diseases. Conversely, allergen immunotherapy (AIT) modulates T FR cells abundance and function to promote immune tolerance. This review focus on the role of T FR cells in allergic diseases and AIT, with the objective of providing novel insights into the mechanisms underlying immune tolerance of AIT and proposing the potential targeting of T FR cells in the context of allergic diseases. RECENT FINDINGS Numerous studies have consistently demonstrated that T FR cells play a pivotal role in the inhibition of class switch recombination to IgE in both humans and specific murine models. This suppression is attributed to the actions of neuritin and IL-10 secreted by T FR cells, which exert direct and indirect effects on B cells. In patients with allergic rhinitis, reduced frequencies of circulating or tonsillar T FR cells have been reported, along with impaired functionality in suppressing IgE production. AIT, whether administered subcutaneously or sublingually, reinstates the frequency and functionality of T FR cells in allergic rhinitis patients, accompanied by changes of the chromatin accessibility of T FR cells. The increase in T FR cell frequency following AIT is associated with the amelioration of clinical symptoms. SUMMARY T FR cells exert an inhibitory effect on IgE production and demonstrate a correlation with the clinical efficacy of AIT in patients with allergic rhinitis, suggesting T FR cells hold promise as a therapeutic target for allergic diseases and potential biomarker for AIT.

Abstract
PURPOSE OF REVIEW This review aimed to introduce the pharmacotherapy of allergic rhinitis according to the 2022 updated Chinese guidelines. RECENT FINDINGS Despite recent advances in basic and clinical research worldwide, pharmacotherapy remains a mainstream in allergic rhinitis treatment. Usually, the first-line drugs, involving intranasal corticosteroids, second-generation oral and intranasal H1-antihistamines, or leukotriene receptor antagonists, can achieve acceptable outcomes in the treatment of allergic rhinitis. The second-line drugs, such as oral corticosteroids, intranasal decongestants and intranasal anticholinergics, can assist in controlling severe symptoms, like nasal congestion/blockage and watery rhinorrhea. For those with moderate-to-severe allergic rhinitis, evidence-based stepwise strategies are suitable, in which the types and dosages of drugs are de-escalated or upgraded according to their therapeutic efficacy. Meanwhile, omalizumab, a novel biological agent, has burgeoned to satisfy the need of patients. SUMMARY This review highlights the staples in Chinese guidelines about the pharmacotherapy for allergic rhinitis to better understand the guidelines and promote the clinical practice.
