RESUMO

Allergic rhinitis (AR) is a widespread disease, and its prevalence is still growing. AR may be associated with other diseases, including conjunctivitis, rhinosinusitis, asthma, food allergy, and atopic dermatitis. Diagnosis is based on history, physical examination, documentation of sensitization, such as the production of allergen-specific IgE, also using molecular diagnostics in selected patients. Treatments is based on education, engagement, allergen avoidance, non-pharmacological and pharmacological remedies, and allergen-specific immunotherapy (Ait). Symptomatic treatments mainly concern intranasal/oral antihistamines and/or nasal corticosteroids. This article also aims to discuss new management strategies for AR patients. The self-management of allergic rhinitis could include new strategies. In this regard, particular interest should be considered to intranasal corticosteroids and antihistamines without medical prescription, probiotics and other natural substances, and new formulations (tablets) of Ait.

RESUMO

INTRODUCTION: Allergic rhinitis (AR) in children is a common condition that is a public health problem. Despite a well-codified treatment, clinical improvement is not the rule. AIM: To identify factors affecting the improvement of allergic rhinitis in children under symptomatic treatment. METHODS: A 12-year retrospective descriptive study that included children aged 3 to 15 years, followed for allergic rhinitis. The search for explanatory factors for improvement under treatment was done using a binary logistic regression model. RESULTS: 52 children were included, with a mean age of 7 years (±3). A familial atopy history was present in 37 patients (71%). The presence of factors aggravating allergy was noted, including antibiotic consumption: 31 patients (60%) and overweight: 15 patients (29%). Associated asthma was noted in 42 patients (81%). The allergenic profile has regained a predominance of dust mite allergy (71%) and a significant frequency of multiallergies (79%). Management included therapeutic education and drug treatment. There was improvement in rhinitis in 27 patients (52%) and improvement in asthma in 26 patients (50%). Overweight and high consumption of antibiotics had a negative impact on the therapeutic outcome. A good therapeutic education had a favorable impact. CONCLUSION: AR is a debilitating condition requiring prolonged therapeutic education and drug treatment. The prescription of antibiotics in children with allergic rhinitis should be sparing and weight monitored.

RESUMO

Allergic rhinitis is a common ailment in primary and acute care settings. Diagnosis is clinical, by means of history and physical examination. Referral to an allergist is considered when symptoms are difficult to manage and/or confirmation by means of further testing is desired. Management of allergic rhinitis should not be considered trivial, as multiple secondary effects can present as the course progresses. Several treatment modalities exist but should begin with glucocorticoid nasal sprays and systemic second- or third-generation antihistamines.

RESUMO

For the first time 15 years ago, tablet allergen immunotherapy (T-AIT) formulations were approved by regulatory agencies for treating allergic rhinitis caused by grass pollen in adults and children aged >5 years. Extensive evidences existed about effectiveness and safety of AIT. However, the safety profile is particularly compelling in children. Generally, T-AIT causes local reactions, mostly in the oral cavity, that are usually mild-to-moderate and often self-resolving. However, systemic allergic reactions are also observed with T-AIT, anaphylaxis representing the most fearsome adverse event, considering that it occurs in subjects treated for allergic rhinitis. Therefore, we conducted a literature search of patients reporting anaphylaxis because of T-AIT. Nine cases of anaphylactic reactions were reported in literature. Notably, no death was reported using T-AIT. This outcome was very important as it underscored the substantial safety of T-AIT. However, T-AIT deserves careful attention, mainly in the pediatric population. In this regard, after the first report of anaphylactic reaction at the first administration of T-AIT, manufacturers recommended that the first dose should be administered in a medical facility in the presence of staff with experience in managing anaphylaxis and the patient should be observed for at least 30 min. Interestingly, reported anaphylactic reactions were due to grass pollen extracts, with no report concerning other allergen extracts. However, it is relevant to note that anaphylactic reactions because of T-AIT are not reported in recent years.

RESUMO

Asthma and obstructive sleep apnea (OSA) are common respiratory disorders. They share characteristics such as airway obstruction, poor sleep quality, and low quality of life. They are often present as comorbidities, along with obesity, gastroesophageal reflux disease (GERD), and allergic rhinitis (AR), which impacts the disease's control. In recent years, there has been discussion about the association between these conditions and their pathophysiological and clinical consequences, resulting in worse health outcomes, increased healthcare resource consumption, prolonged hospital stays, and increased morbidity and mortality. Some studies demonstrate that treatment with continuous positive airway pressure (CPAP) can have a beneficial effect on both pathologies. This review summarizes the existing evidence of the association between asthma and OSA at their pathophysiological, epidemiological, clinical, and therapeutic levels. It intends to raise awareness among healthcare professionals about these conditions and the need for further research.

RESUMO

OBJECTIVES: To observe effects of acupuncture at "Die E acupoint" on the protein expression levels of Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), nuclear transcription factor κB (NF-κB), transcription factor T-bet (T-bet), and GATA-binding protein-3 (GATA-3) in the nasal mucosa and the serum contents of related inflammatory cytokines in rats with allergic rhinitis, so as to explore the mechanism of acupuncture in treating allergic rhinitis. METHODS: Twenty-four healthy SD rats were randomly divided into blank, model, acupuncture, and sham acupuncture groups, with 6 rats in each group. The rat model of allergic rhinitis was established by using ovalbumin induction. The rats in the acupuncture group received bilateral acupuncture at the "Die E acupoint" with a depth of 15-20 mm, while the rats in the sham acupuncture group received only sham acupuncture (light and shallow acupunture of the skin at the "Die E acupoint" ). Both interventions were performed once daily for a total of 6 days. Behavioral scores of rats in each group were recorded. Pathological changes of nasal mucosa were observed by H.E. staining. Serum contents of IgE, ovalbumin-specific IgE (OVA-sIgE), interferon(IFN)-γ, interleukin(IL)-4, IL-10 and IL-17 were measured by ELISA and the protein expression levels of T-bet, GATA-3, TLR4, MyD88 and NF-κB p65 in the nasal mucosa were detected by Western blot. RESULTS: After modeling, compared with the blank group, rats in the model group showed increased behavioral scores, serum IgE, OVA-sIgE, IL-4, and IL-17 contents, and nasal mucosal GATA-3, TLR4, MyD88, and NF-κB p65 protein expression levels (P<0.05), whereas the contents of serum IFN-γ, IL-10 and the protein expression level of T-bet in the nasal mucosa were decreased (P<0.05). Comparison between the EA and model groups showed that acupuncture intervention can decrease the behavioral scores of rats with allergic rhinitis, the contents of serum IgE, OVA-sIgE, IL-4, IL-17, and the protein expression levels of GATA-3, TLR4, MyD88, and NF-κB p65 in the nasal mucosa (P<0.05), and up-regulate the contents of serum IFN-γ, IL-10, and the nasal mucosal T-bet protein expression level. Sham acupuncture did not have a significant modulating effect on the above indicators. Inflammatory infiltration of nasal mucosa was seen in the model group and sham acupuncture, and the inflammatory reaction was milder in the acupuncture group. CONCLUSIONS: Acupuncture at "Die E acupoint" can alleviate the symptoms of allergic rhinitis and suppress the inflammation of nasal mucosa in rats, which may be related to inhibiting the TLR4/MyD88/NF-κB signaling and balancing the levels of cytokines of Th1/Th2 and Treg/Th17, and T-bet/GATA-3.

RESUMO

OBJECTIVES: To evaluate the efficacy and safety of ringheaded thrumbtack needle in the treatment of allergic rhinitis (AR). METHODS: Clinical studies about treatment of AR with ringheaded thrumbtack needle were searched from databases of CNKI, Wanfang, China Science and Technology Journal, China Biology Medicine disc, PubMed, Embase and Web of Science from their inception to November 2022. Two researchers independently screened the literature and collected related information. The total effective rate, visual analogue scale (VAS) for AR, rhinoconjunctivitis quality of life questionnaire (RQLQ), and recurrence rate were the main outcome indicators. Secondary outcome indicators included quantitative scores of symptoms and signs, 'quartering' symptom evaluation scale, etc. All the included studies were subjected to Meta-analysis using Stata software. RESULTS: A total of 22 clinical studies involving 1 491 participants were included. The results of Meta-analysis indicated that the total effective rate of ringheaded thrumbtack needle in the treatment of AR was higher than that of traditional Chinese and Western medicine ï¼»RR=1.20, 95%CI (1.14, 1.26), P<0.001ï¼½, and recurrence rate is lower than conventional therapy ï¼»OR=0.35, 95%CI (0.14, 0.89), P=0.027ï¼½. Moreover, The VAS score ï¼»WMD=-1.30, 95%CI (-1.85, -0.75), P<0.001ï¼½ and RQLQ score ï¼»WMD=-6.75, 95%CI (-12.74, -0.76), P=0.027ï¼½ of AR treated by ringheaded thrumbtack needle were lower than those of traditional Chinese and Western medicine. CONCLUSIONS: Ringheaded thrumbtack needle can improve the total effective rate, reduce the disease recurrence, and improve the symptoms of discomfort when AR outbreaks, and has no significant adverse reactions. However, the reliability is limited. Thus, it is still necessary to improve the level of evidence quality by including researches with large samples, rigorous design and international standards.

RESUMO

Allergic rhinitis (AR), a common disease in otolaryngology, is a key risk factor for poorly controlled asthma and many complications, although it is not life-threatening. The negative impact of AR on social productive forces and human health is no less than that of asthma. Dendritic cells (DCs) play an important role in AR. In addition to sharing some of DC's biological characteristics, DCs-derived exosomes (DEXs) can promote the priming and activation of T cells and the maturation and differentiation of T helper type 2 (Th2) cells. Multiple signaling pathways in AR can be modulated by DEXs, which present allergens and participate in allergic immune responses. Anti-allergic drugs can be carried by DEXs to alleviate allergic airway inflammation and treat Th2-mediated AR effectively. Therefore, DEXs are crucial in the pathogenesis and treatment of AR.

RESUMO

OBJECTIVE: To evaluate the risk of IgE sensitization and symptoms to shrimp in a population that has received AIT with polymerized mite extract. METHODS: Patients with allergic rhinitis sensitized to dust mites (Dermatophogides spp) with an indication for mite AIT were included. Those patients who had not yet received AIT or had received less than 6 doses were included as controls and those who had received more than 24 doses of AIT were included as cases. Sensitization to shrimp was assessed by skin prick test with complete shrimp extract and/or shrimp-specific IgE. RESULTS: A total of 68 patients were included; 47 cases and 21 controls. When calculating the odds ratio of sensitization according to time with immunotherapy we observed that there were no differences between the group of cases and controls (OR 0.76 95% CI 0.26 to 2.22 p 0.7 by MacNemar technique). Factors such as consumption or not of shrimp and frequency of consumption do not seem to be related to the outcome. CONCLUSION: In contrast to what was reported with aqueous extracts, we observed that AIT with polymerized extracts is not a risk factor for shrimp sensitization. It is necessary to reproduce these results with a larger sample size to explore other factors.


OBJETIVO: Evaluar el riesgo de sensibilización IgE y síntomas a camarón en una población que ha recibido AIT con extracto polimerizado para ácaros. MÉTODOS: Se incluyeron pacientes con rinitis alérgica sensibilizados a ácaros del polvo (Dermatophogides spp) con indicación de AIT para ácaros. Aquellos pacientes que no habían aún recibido AIT o llevaban menos de seis dosis, fueron incluidos como controles, y aquellos que llevaban más de 24 dosis de AIT, fueron incluidos como casos. Se evaluó la sensibilización a camarón mediante prueba cutánea con extracto completo de camarón y/o IgE específica a camarón. RESULTADOS: En total, 68 pacientes fueron incluidos; 47 casos y 21 controles. Al calcular el odds ratio de la sensibilización de acuerdo al tiempo con la inmunoterapia, observamos que no había diferencias entre el grupo de casos y controles (OR 0,76 95% IC 0,26 a 2,22 p 0,7 por técnica de MacNemar). Factores como el consumo o no de camarón y la frecuencia de consumo, no parecen estar relacionados con el desenlace. CONCLUSIÓN: A diferencia de lo reportado con extractos acuosos, observamos de AIT con extractos polimerizados para no es un factor de riesgo para la sensibilización a camarón. Es necesario reproducir estos resultados con un mayor tamaño de muestra que permita explorar otros factores.

RESUMO

Combined allergic rhinitis and asthma syndrome (CARAS) refers to a common respiratory disease that occurs simultaneously with clinical or subclinical allergic symptoms of the upper respiratory tract (allergic rhinitis) and the lower respiratory tract (asthma). The incidence of CARAS is high and the quality of life of the patients is greatly affected. At present, treatment of this comprehensive disease is often carried out separately in the otorhinolaryngology and respiratory departments. One of the reasons is a lack of coordinated treatment consensus on the comprehensive management of this disease. As a common respiratory disease, this syndrome also has a profound clinical basis of traditional Chinese medicine in its diagnosis and treatment. Therefore, the Allergy Committee of Chinese Association of Integrative Medicine organized domestic experts in respiratory medicine, otolaryngology, allergy, pediatrics, traditional Chinese Medicine internal medicine and other related fields to discuss and summarize the etiology and anatomical characteristics, pathophysiology and pathogenesis, laboratory examination, diagnostic evaluation and differential diagnosis as well as treatment of both traditional Chinese medicine and western medicine, in order to provide integrated diagnosis and treatment opinions for this common integrative disease of upper and lower respiratory system in clinical practice.

RESUMO

BACKGROUND: Allergic rhinitis constitutes a widespread health concern, with traditional treatments often proving to be painful and ineffective. Acupuncture targeting the pterygopalatine fossa proves effective but is complicated due to the intricate nearby anatomy. METHODS: To enhance the safety and precision in targeting the pterygopalatine fossa, we introduce a deep learning-based model to refine the segmentation of the pterygopalatine fossa. Our model expands the U-Net framework with DenseASPP and integrates an attention mechanism for enhanced precision in the localisation and segmentation of the pterygopalatine fossa. RESULTS: The model achieves Dice Similarity Coefficient of 93.89% and 95% Hausdorff Distance of 2.53 mm with significant precision. Remarkably, it only uses 1.98 M parameters. CONCLUSIONS: Our deep learning approach yields significant advancements in localising and segmenting the pterygopalatine fossa, providing a reliable basis for guiding pterygopalatine fossa-assisted punctures.

RESUMO

Acupuncture is one of the most effective complementary therapies for allergic rhinitis (AR) and has been recommended by several clinical practice guidelines (CPGs) for AR. However, these CPGs mentioned acupuncture without making recommendations for clinical implementation and therapeutic protocols, therefore limiting the applicability of acupuncture therapies for AR. Hence, for the benefit of acupuncture practitioners around the world, the World Federation of Acupuncture-moxibustion Societies have initiated a project to develop the CPG for the use of acupuncture and moxibustion to treat AR. This CPG was developed according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology, referring to the principles of the World Health Organization Handbook for Guideline Development. During the development of the CPG, the guideline development group (GDG) played an important role. The clinical questions, recommendations and therapeutic protocols were all formulated by the GDG using the modified Delphi method. The CPG contains recommendations for 15 clinical questions about the use of acupuncture and moxibustion interventions. These include one strong recommendation for the intervention based on high-quality evidence, three conditional recommendations for either the intervention or standard care, and 11 conditional recommendations for the intervention based on very low quality of evidence. The CPG also provides one filiform needle acupuncture protocol and five moxibustion protocols extracted based on the protocols presented in randomized controlled trials reviewed by the GDG.

RESUMO

Allergic rhinitis is a chronic nasal mucosal inflammation characterized by upper airway hyperresponsiveness, involving a variety of immune cells and inflammatory mediators. Drugs, immunotherapy, and surgical operation are the principal treatments at present. The study found that mesenchymal stem cells have the ability of immune regulation and have a promising clinical application in the treatment of allergic rhinitis. In this review, the action mechanism of mesenchymal stem cells, the immunomodulatory effect of mesenchymal stem cells on the key cells of allergic rhinitis, and the challenges of clinical application are reviewed, to provide new directions for the treatment of allergic rhinitis.

RESUMO

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.

RESUMO

AIM: To provide paediatricians with a summary of efficacy and safety of SQ sublingual immunotherapy (SLIT) tablets from phase three, randomised, double-blind, placebo-controlled trials in children and adolescents with allergic rhinitis or rhinoconjunctivitis, with and without asthma. METHODS: PubMed searches were conducted and unpublished data were included if necessary. RESULTS: Of the 93 publications, 12 were identified reporting 10 trials. One trial was excluded as paediatric-specific efficacy data were unavailable. The nine eligible trials evaluated grass, house dust mite, ragweed and tree SLIT tablets. Consistent reductions in allergic rhinitis or rhinoconjunctivitis symptoms and medication use were observed with SQ SLIT tablets versus placebo. In a five-year trial, sustained reduction of allergic rhinoconjunctivitis symptoms, asthma symptoms and medication use were observed with SQ grass SLIT tablet versus placebo. The number-needed-to-treat to prevent asthma symptoms and medication use in one additional child during follow-up was lowest in younger children. SQ SLIT tablets were generally well tolerated across trials. CONCLUSION: Evidence supports use of SQ SLIT tablets in children and adolescents with allergic rhinitis or rhinoconjunctivitis, with and without asthma. Long-term data demonstrate disease-modifying effects of SQ grass SLIT tablet and suggest the clinical relevance of initiating allergy immunotherapy earlier in the disease course.

RESUMO

BACKGROUND: The symptoms of house dust mite (HDM)-induced allergic rhinitis (AR) vary with changes in exposure related to the weather or the domestic environment. In allergen immunotherapy (AIT) studies, a certain level of AR disease activity is necessary to demonstrate treatment efficacy; the latter can be underestimated if a substantial proportion of the patient population is weakly symptomatic. OBJECTIVE: To better estimate the real treatment effect of a HDM sublingual AIT (SLIT) tablet, we analysed the results of natural field studies in detail by applying a tertile approach. METHODS: We used data from three randomised, controlled trials (RCT) in a total of 2585 patients with AR treated with the 300 index of reactivity (IR) HDM SLIT-tablet or placebo. The study centres were grouped into tertiles according to the level of combined symptom and medication scores in patients in the placebo group. In each tertile, the difference between SLIT and placebo was assessed through an analysis of covariance. RESULTS: In the three RCTs, combined scores were found to be similar in the SLIT and placebo groups in the low tertiles. The treatment effect of the 300 IR HDM tablet increased in the medium and high tertiles, with notably significant differences versus placebo in the highest tertile and greater (ranging from -21% to -39%) than in the entire study population (-13% to -20%). The positive relationship between treatment efficacy and the combined score in each tertile was independent of the RCT and the score used. CONCLUSION AND CLINICAL RELEVANCE: Application of the tertile approach to AIT studies in a field in which many variables interact strongly might provide more accurate and meaningful measurements of efficacy and benefit for patients, better reflecting their real-life condition.

RESUMO

Importance: Allergic rhinitis affects an estimated 15% of the US population (approximately 50 million individuals) and is associated with the presence of asthma, eczema, chronic or recurrent sinusitis, cough, and both tension and migraine headaches. Observations: Allergic rhinitis occurs when disruption of the epithelial barrier allows allergens to penetrate the mucosal epithelium of nasal passages, inducing a T-helper type 2 inflammatory response and production of allergen-specific IgE. Allergic rhinitis typically presents with symptoms of nasal congestion, rhinorrhea, postnasal drainage, sneezing, and itching of the eyes, nose, and throat. In an international study, the most common symptoms of allergic rhinitis were rhinorrhea (90.38%) and nasal congestion (94.23%). Patients with nonallergic rhinitis present primarily with nasal congestion and postnasal drainage frequently associated with sinus pressure, ear plugging, muffled sounds and pain, and eustachian tube dysfunction that is less responsive to nasal corticosteroids. Patients with seasonal allergic rhinitis typically have physical examination findings of edematous and pale turbinates. Patients with perennial allergic rhinitis typically have erythematous and inflamed turbinates with serous secretions that appear similar to other forms of chronic rhinitis at physical examination. Patients with nonallergic rhinitis have negative test results for specific IgE aeroallergens. Intermittent allergic rhinitis is defined as symptoms occurring less than 4 consecutive days/week or less than 4 consecutive weeks/year. Persistent allergic rhinitis is defined as symptoms occurring more often than 4 consecutive days/week and for more than 4 consecutive weeks/year. Patients with allergic rhinitis should avoid inciting allergens. In addition, first-line treatment for mild intermittent or mild persistent allergic rhinitis may include a second-generation H1 antihistamine (eg, cetirizine, fexofenadine, desloratadine, loratadine) or an intranasal antihistamine (eg, azelastine, olopatadine), whereas patients with persistent moderate to severe allergic rhinitis should be treated initially with an intranasal corticosteroid (eg, fluticasone, triamcinolone, budesonide, mometasone) either alone or in combination with an intranasal antihistamine. In contrast, first-line therapy for patients with nonallergic rhinitis consists of an intranasal antihistamine as monotherapy or in combination with an intranasal corticosteroid. Conclusions and Relevance: Allergic rhinitis is associated with symptoms of nasal congestion, sneezing, and itching of the eyes, nose, and throat. Patients with allergic rhinitis should be instructed to avoid inciting allergens. Therapies include second-generation H1 antihistamines (eg, cetirizine, fexofenadine, desloratadine, loratadine), intranasal antihistamines (eg, azelastine, olopatadine), and intranasal corticosteroids (eg, fluticasone, triamcinolone, budesonide, mometasone) and should be selected based on the severity and frequency of symptoms and patient preference.

RESUMO

Allergen-specific immunotherapy (AIT) has confirmed its efficacy in improving the symptoms of allergic rhinitis. However, no reliable biomarkers have been identified to predict the efficacy of AIT were found. We aimed to find clinical and immunological markers to predict efficacy in children after 2 years of sublingual immunotherapy (SLIT). A total of 285 children diagnosed with allergic rhinitis were recruited. The clinical efficacy was evaluated by comparing endpoint and baseline symptom and medication scores (SMS). Baseline clinical and immunological markers (serum total and specific immunoglobulin [Ig]E) and their correlation with clinical efficacy were analyzed. Of the 285 children recruited, 249 completed the 2-year SLIT program. After 2 years of SLIT, 68.3% of the children showed a significant response. Children in the Remarkable Response Group had the highest baseline SMS and most extended disease duration, followed by the Effective Relief and Unresponsive Group. Correlation analysis demonstrated that SMS improvement was positively correlated with baseline SMS (r=0.67) and disease duration (r=0.35). SMS improvement was not correlated with age, body mass index, total or specific IgE levels, or their ratios. Our results show that baseline SMS and disease duration can predict the efficacy of SLIT. Our study can guide the selection of suitable candidates for SLIT.

RESUMO

OBJECTIVE: Aim: To carry out a comprehensive evaluation of treatment modification for patients with seasonal allergic rhinitis (SAR) complicated by anxiety-neurotic disorders. PATIENTS AND METHODS: Materials and Methods: Patients with SAR in the acute stage on the background of anxiety disorders were studied. Immunological studies were carried out, an assessment of the dynamics of indicators of the quality of life of patients, the level of anxiety / depression was assessed. In the clinical group, a variant of therapy modification was proposed. RESULTS: Results: Significant changes in the subpopulation ratio of lymphocytes, an increase in the immunoregulatory index, which indicated the severity of the immunological process, were revealed in SAR patients in the acute stage against the background of anxiety disorders. At the same time, a significant activation of the humoral link of immunity was observed: an increase and a significant increase in IgE in the blood serum and an increase in the content of sIgA in the nasal secretion. In most patients, eosinophilia was found in the peripheral blood and in the rhinocytogram before treatment. In the study of the quality of life of patients, changes in many parameters were found. CONCLUSION: Conclusions: The combination of "Nazafort Allergy Protection" and Atarax seems to be the most successful, which significantly improved the physical and psycho-emotional state of patients with SAR, complicated by anxiety and neurotic disorders. This combination led to an increase in the stress resistance of patients.
