Allergic disorders and risk of depression: A systematic review and meta-analysis of 51 large-scale studies

Health-related quality of life in severe hypersensitivity reactions: focus on severe allergic asthma and hymenoptera venom anaphylaxis-a cross-sectional study

Background

Growing evidence reveals the important role of clinical psychological factors in chronic-immune diseases. The aim of this study was to investigate Health-Related Quality of Life (HR-QoL), depression, anxiety, and alexithymia in patients with severe hypersensitivity reactions such as Severe Allergic Asthma (SAA) and Hymenoptera Venom Anaphylaxis (HVA).

Methods

The Short-Form Health Survey-36 (SF-36), the Beck Depression Inventory Questionnaire (BDI-II), the Hamilton Anxiety Rating Scale (HAM-A) and the Toronto Alexithymia Scale (TAS-20) were used to assess HR-QoL and clinical psychological features of patients with SAA and HVA.

Results

Overall, 78 patients were recruited. Patients with SAA (n = 35) reported lower scores for physical functioning [65 (58-75) vs. 90 (85-95); p = <0.001], role limitations due to physical health [25 (0-50) vs. 62 (50-75); p = 0.004], bodily pain [47.5 (41.1-61.3) vs. 55.5 (55-96); p = 0.001], general health [40 (30-60) vs. 70 (50-80); p = 0.0003] and social functioning [50 (37.5-62.5) vs. 62.5 (54.9-75); p = 0.007] while higher scores for depressive symptoms [14 (11-15.4) vs. (9.5 (6-15.4); p = 0.05)] compared to HVA patients (n = 43). All the dimensions of SF-36 were negatively correlated with anxiety (r from -0.26 to -0.66; p all < 0.01) and depressive symptoms (r from -0.44 to -0.73; p all < 0.001). Alexithymia was negatively correlated with vitality (r = -0.28; p = 0.02) and mental health (r = -027; p = 0.03). Additionally, patients with alexithymia (38% of participants) showed higher levels of depressive symptoms [9.5 (10-19) vs. 14 (6-13.9); p = 0.005] and anxiety levels [31 (27.9-35) vs. 24 (16-33.9); p = 0.02]; they also showed less vitality [40 (39.9-50) vs. 55 (50-60) p = 0.01], social functioning [50 (37.5-62.5) vs. 62.5 (50 vs. 75); p = 0.01] and mental health [48 (44-60) vs. 68 (56-76); p = 0.004].

Conclusion

Clinical psychological features due to severe hypersensitive reactions may contribute to the patient's perceived HR-QoL. Focused clinical psychological interventions should be promoted to improve the clinical management of such conditions.

Factor Structures in the Depressive Symptoms Domains in the 9Q for Northern Thai Adults and Their Association with Chronic Diseases

Most of the common models to examine depression are one-factor models; however, previous studies provided several-factor structure models on each depressive symptom using the Patient Health Questionnaire-9 (PHQ-9). The Nine-Questions Depression-Rating Scale (9Q) is an alternative assessment tool that was developed for assessing the severity of depressive symptoms in Thai adults. This study aimed to examine the factor structure of this tool based on the factor structure models for the PHQ-9 provided in previous studies using confirmatory factor analysis (CFA). We also examined the association of chronic diseases and depressive symptoms using the Multiple Indicators Multiple Causes model among 1346 participants aged 19 years old or more without psychiatric disorders. The results show that the two-factor CFA model with six items in the cognitive-affective domain and three items in the somatic domain provided the best fit for depressive symptoms in the study population (RMSEA = 0.077, CFI = 0.953, TLI = 0.936). Dyslipidemia was positively associated with both cognitive-affective symptoms (β = 0.120) and somatic depressive symptoms (β = 0.080). Allergies were associated with a higher level of cognitive-affective depressive symptoms (β = 0.087), while migraine (β = 0.114) and peptic ulcer disease (β = 0.062) were associated with a higher level of somatic symptoms. Increased age was associated with a lower level of somatic symptoms (β = -0.088). Our findings suggested that considering depressive symptoms as two dimensions yields a better fit for depressive symptoms. The co-occurrence of chronic diseases associated with depressive symptoms should be monitored.

Effects of changes in daily life attributed to COVID-19 on allergic diseases among Korean adolescents

OBJECTIVE

The daily lives of adolescents have changed significantly because of COVID-19 pandemic. We investigated the effects of changes in daily life attributed to COVID-19 on allergic diseases among Korean adolescents.

METHODS

Data from the 2021 Korea Youth Risk Behavior Survey were used. In total, 54,848 survey participants were included in the analysis. Allergic diseases included allergic rhinitis, atopic dermatitis, and asthma. Changes attributed to COVID-19 included family economic difficulties, physical activity, breakfast skipping frequency, alcohol consumption, smoking, and depressive moods. Chi-square tests and multiple logistic regression analyses were conducted to examine the impact of changes in daily life attributed to COVID-19 on allergic diseases.

RESULTS

Among the Korean adolescents surveyed, 29.8% experienced a deterioration in their economic status due to COVID-19, 49.1% reported decreased physical activity, 2.8% reported increased alcohol consumption, 1.0% reported an increase in their smoking behavior, and 36.9% reported an increase in depressive moods. Those diagnosed with atopic dermatitis, allergic rhinitis, or asthma within the previous 12 months accounted for 17.1%, 6.2%, and 1.0% of the population, respectively. Adolescents who were significantly affected by COVID-19 in their daily lives were frequently diagnosed with allergic diseases within the last 12 months.

CONCLUSION

Changes in daily life due to COVID-19, including decreased physical activity and increased depressive mood, were common in adolescents and were associated with an increased prevalence of allergic diseases. Since changes in daily life due to the pandemic may increase the burden of allergic disease, additional interventions for disease management should be considered.

Immune Dysregulation, Inflammation in Characterizing Women with Vulvodynia, Depression, and Both

Background: Depression and vulvodynia are often comorbid. The onset of depression and vulvodynia may be immune and/or stress/environmentally induced. We explored whether vulvodynia, depression, or both occur in response to a Th1-mediated versus Th2-mediated immune response. Materials and Methods: We analyzed data from a case-control study of clinically confirmed vulvodynia and history of depression determined through structured clinical interviews. Immune dysregulation and inflammation were categorized based on the following self-reported conditions: rheumatoid arthritis, Sjogren's disease, scleroderma, systemic lupus erythematosus, inflammatory bowel disease, fibromyalgia, osteoarthritis, polycystic ovarian syndrome, diabetes mellitus, uterine fibroids, asthma, atopic dermatitis, and allergic rhinitis. Logistic regression analyses were adjusted for marital status, body mass index, age, and pack years. Results: Women with systemic immune dysregulation had higher odds of depression (adjusted odds ratio [aOR] = 1.61, confidence interval [95% CI]: 0.65-3.98), vulvodynia (aOR = 2.45, 95% CI: 1.00-5.96), and comorbid depression and vulvodynia (aOR = 4.93, 95% CI: 2.19-11.10) versus neither condition. Women reporting local immune dysregulation had similar odds of depression (aOR = 1.89, 95% CI: 0.99-3.59), vulvodynia (aOR = 2.12, 95% CI: 1.08-4.18), and comorbid depression and vulvodynia (aOR = 1.96, 95% CI: 0.98-3.90). Women with Th2 inflammation had similar odds of depression (aOR = 2.23, 95% CI: 1.05-4.77) and vulvodynia (aOR = 2.56, 95% CI: 1.20-5.49). Women with Th1 or Th2 inflammation had similar odds of comorbid depression and vulvodynia (aOR = 3.03, 95% CI: 1.48-6.19; aOR = 3.14, 95% CI: 1.49-6.60, respectively). Conclusions: Our results suggest that an imbalance of cytokines, indicated by the presence of one or more immune-related health conditions, is associated with an increased risk of vulvodynia and/or depression.

Resting state functional connectivity changes following mindfulness-based stress reduction predict improvements in disease control for patients with asthma

BACKGROUND

The staggering morbidity associated with chronic inflammatory diseases can be reduced by psychological interventions, including Mindfulness-Based Stress Reduction (MBSR). Proposed mechanisms for MBSR's beneficial effects include changes in salience network function. Salience network perturbations are also associated with chronic inflammation, including airway inflammation in asthma, a chronic inflammatory disease affecting approximately 10% of the population. However, no studies have examined whether MBSR-related improvements in disease control are related to changes in salience network function.

METHODS

Adults with asthma were randomized to 8 weeks of MBSR or a waitlist control group. Resting state functional connectivity was measured using fMRI before randomization, immediately post-intervention, and 4 months post-intervention. Using key salience network regions as seeds, we calculated group differences in change in functional connectivity over time and examined whether functional connectivity changes were associated with increased mindfulness, improved asthma control, and decreased inflammatory biomarkers.

RESULTS

The MBSR group showed greater increases in functional connectivity between salience network regions relative to the waitlist group. Improvements in asthma control correlated with increased functional connectivity between the salience network and regions important for attention control and emotion regulation. Improvements in inflammatory biomarkers were related to decreased functional connectivity between the salience network and other networks.

CONCLUSIONS

Increased resting salience network coherence and connectivity with networks that subserve attention and emotion regulation may contribute to the benefits of MBSR for patients with asthma. Understanding the neural underpinnings of MBSR-related benefits in patients is a critical step towards optimizing brain-targeted interventions for chronic inflammatory disease management.

Associations of allergy-related outcomes with depression in the US adults

Evidences showed the link between allergy and depression, while the relationships of depression with allergy-related outcomes is insufficient. The objective of this study is to evaluate and compare the relationship of depression with allergy-related outcomes assessed using two different outcome indicators, in a population-based study. A cross-sectional study was performed of 1094 participants in the 2005-2006 National Health and Nutrition Examination Survey (NHANES). The self-reported allergic symptoms of allergic rhinitis (AR) status and immunoglobulin E (IgE) were used to evaluate the allergy-related outcomes. The depression disorder was defined as the ≥ 10 points on the Patient Health Questionnaire-9. Logistic and linear regression models were performed to illustrate the associations of depression and allergy-related outcomes. The prevalence of AR and depression was 34.2% and 6.8%, respectively. The odds of depression were 8.6% higher in participants with AR patients compared those without AR [odds ratio (OR) = 1.739, 95% confidence interval (CI): (1.034, 2.933)], while the odds of depression in participants with allergic sensitization and without allergic sensitization were not found significant difference. Allergy is positively associated with depression disorder, and patients with allergy-related outcomes, such as AR, may be at higher risk of depression, while the IgE level was not founded to be related with depression. In the treatment of AR patients with depression symptoms, early detection and management of mental problems are of importance.

Depression, worry, and loneliness are associated with subsequent risk of hospitalization for COVID-19: a prospective study

BACKGROUND

Pre-pandemic psychological distress is associated with increased susceptibility to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, but associations with the coronavirus disease 2019 (COVID-19) severity are not established. The authors examined the associations between distress prior to SARS-CoV-2 infection and subsequent risk of hospitalization.

METHODS

Between April 2020 (baseline) and April 2021, we followed 54 781 participants from three ongoing cohorts: Nurses' Health Study II (NHSII), Nurses' Health Study 3 (NHS3), and the Growing Up Today Study (GUTS) who reported no current or prior SARS-CoV-2 infection at baseline. Chronic depression was assessed during 2010-2019. Depression, anxiety, worry about COVID-19, perceived stress, and loneliness were measured at baseline. SARS-CoV-2 infection and hospitalization due to COVID-19 was self-reported. Relative risks (RRs) were calculated by Poisson regression.

RESULTS

3663 participants reported a positive SARS-CoV-2 test (mean age = 55.0 years, standard deviation = 13.8) during follow-up. Among these participants, chronic depression prior to the pandemic [RR = 1.72; 95% confidence interval (CI) 1.20-2.46], and probable depression (RR = 1.81, 95% CI 1.08-3.03), being very worried about COVID-19 (RR = 1.79; 95% CI 1.12-2.86), and loneliness (RR = 1.81, 95% CI 1.02-3.20) reported at baseline were each associated with subsequent COVID-19 hospitalization, adjusting for demographic factors and healthcare worker status. Anxiety and perceived stress were not associated with hospitalization. Depression, worry about COVID-19, and loneliness were as strongly associated with hospitalization as were high cholesterol and hypertension, established risk factors for COVID-19 severity.

CONCLUSIONS

Psychological distress may be a risk factor for hospitalization in patients with SARS-CoV-2 infection. Assessment of psychological distress may identify patients at greater risk of hospitalization. Future work should examine whether addressing distress improves physical health outcomes.

Brain response in allergic rhinitis: Profile and proposal

In addition to typical nasal symptoms, patients with allergic rhinitis (AR) will further lead to symptoms related to brain function such as hyposmia, anxiety, depression, cognitive impairment, memory loss, etc., which seriously affect the quality of life of patients and bring a heavy burden to the patient's family and society. Some scholars have speculated that there may be potential "nose-brain communication" mechanism in AR that rely on neuro-immunity. This mechanism plays an important role in AR-associated brain response process. However, no study has directly demonstrated which neural circuits will change in the connection between the nose and brain during the onset of AR, and the mechanism which underlines this question is also lack. Focusing on the topic of "nose-brain communication", this paper systematically summarizes the latest research progress between AR and related brain responses and discusses the mechanism of AR-related neurological phenotypes. Hope new diagnostic and therapeutic targets to ameliorate the brain function-related symptoms and improve the quality of life of AR patients will be developed.

Psychiatric comorbidity and quality of life in patients with drug hypersensitivity

Background: Compared with advances in a drug hypersensitivity diagnosis and management, little is known about the mental health status of patients with drug hypersensitivity and the impact of this psychological distress on their quality of life (QoL). Objective: The objectives were to evaluate anxiety, depression, and QoL levels in patients with drug hypersensitivity, assess how some related factors may affect them, and determine the impact of disease on their QoL. Methods: A total of 203 patients with drug hypersensitivity and 80 healthy controls were evaluated with the Beck Anxiety (BAI) and the Depression Inventory (BDI), and the short version of the World Health Organization Quality of Life (WHOQOL-BREF) scale. Results: The mean ± standard deviation (SD) BAI scores of the patients and the controls were 13.46 ± 11.78 and 1.94 ± 1.93, respectively (p < 0.0001). The mean ± SD BDI scores were higher in the patient group (9.23 ± 6.36) than in the control group (2.18 ± 2.02) (p < 0.0001). The patients had significantly increased risk of anxiety versus the controls (48.8% versus 7.5%) (odds ratio [OR] 11.74 [95% confidence {CI}, 4.88-28.20]; p < 0.0001) and depression versus the controls (31.5% versus 6.2%) (OR 6.90 [95% CI, 2.66-17.90]; p = 0.0001). The comparison of patients' BAI and BDI scores showed that those with more severe reactions had higher scores than those with moderate and mild reactions. A negative correlation was found among all WHOQOL-BREF scale domain scores and the BAI and BDI scores. Conclusion: Anxiety and depressive symptoms have a high prevalence in patients with confirmed drug hypersensitivity, which leads to a notable decrease in QoL. Self-administered psychological questionnaires were shown to be useful in the psychological examination and management of patients with drug hypersensitivity. Therefore, we found that psychological support is critical to reducing the negative outcomes of hypersensitivity reactions in patients.

[Asthma and suicidal behavior in adolescents: a literature review]

INTRODUCTION

Adolescence is a difficult time in life and asthma has major psychological consequences for adolescents.

OBJECTIVES

This systematic literature review focused on the association between asthma and suicidal behaviors (suicidal ideations [SI], suicide plans [SP] and suicide attempts [SA]) among adolescents in the general population.

METHOD

Research on Medline for the 1980-2021 period. Objectives This systematic literature review focused on the association between asthma and suicidal behaviors (suicidal ideations [SI], suicide plans [SP] and suicide attempts [SA]) among adolescents in the general population.

RESULTS

An overwhelming majority of the studies taken into consideration demonstrated a significant positive association between asthma and suicidal behaviors. Among the 10 studies assessing SI (with or without SP), 9 of them found a significant positive association between asthma and SI. Eight studies assessed SA; five cross-sectional studies and one prospective study demonstrated a significant positive association between asthma and SA. Only one case-control study did not find a significant positive association between asthma and SA after hospitalization for asthma. The two cross-sectional studies assessing suicidal risk taken as a whole (SI, SP and SA) demonstrated a significant positive association between asthma and at least one suicidal behavior. (OR=1.71; P<0.001). However, several studies did not include depression as an adjustment factor.

CONCLUSION

It is important that healthcare professionals assess suicide risk in adolescent suffering from asthma, the objective being to avoid SA or death from SA.

Relationship between allergic diseases and mental disorders in women: A systematic review and meta-analysis

BACKGROUND

The relationship between allergic diseases (AD) and mental disorders (MD) in women has not been fully systematically evaluated. We aimed at validating this correlation.

METHODS

The relevant cohort and case-control studies from the establishment of the database to February 18, 2022 in PubMed, Embase, and Cochrane library were searched by computer. The researchers conducted the quality evaluation of the included articles by reviewing and discussing with reference to relevant standards, and conducted the analysis of the correlation between female patients with AD and MD by using Review Manager 5.4.

RESULTS

Six observational studies from 2631 studies (n = 1160858 women) were assessed as medium and high-quality studies. The meta-analysis demonstrated that AD was correlated with MD in female patients (OR = 1.21, 95%CI: 1.14-1.29), including asthma (OR = 1.16, 95%CI: 1.11-1.22), allergic rhinitis (OR = 1.31, 95%CI: 1.06-1.63), and atopic dermatitis in women (OR = 1.37, 95%CI: 1.24-1.50) were associated with MD. At the same time, subgroup analysis was performed according to region, study design, criteria of AD and MD, and the results demonstrated that both AD and MD were correlated in these different conditions.

CONCLUSION

Allergic diseases in female patients do have an association with mental disorders.

Increased Risk of Postpartum Depression in Women With Allergic Rhinitis During Pregnancy: A Population-Based Case-Control Study

OBJECTIVES

Allergic rhinitis (AR) is associated with increased risk of major depression in the general population, however, no previous study has evaluated its role among pregnant women. We aimed to investigate the potential impact of AR during pregnancy on the development of postpartum depression (PPD).

METHODS

This is a population-based case-control study. Data were retrieved from the National Health Insurance Research Database (NHIRD). Medical records of a total of 199 470 deliveries during 2000 and 2010 were identified. Among which, 1416 women with PPD within 12 months after delivery were classified as the case group, while 198 054 women without PPD after delivery formed the control group. Univariate and multivariate regression analyses were conducted to determine the associations between AR during pregnancies and other study variables with PPD.

RESULTS

AR during pregnancy was found in 9.53% women who developed PPD and 5.44% in women without PPD. After adjusting for age at delivery, income level, various pregnancy and delivery-related conditions, asthma, atopic dermatitis and other medical comorbidities in the multivariate analysis, AR was significantly associated with increased odds of PPD (aOR: 1.498, 95% CI: 1.222-1.836).

CONCLUSION

AR during pregnancy was independently and significantly associated with an approximately 50% increased risk of PPD among women giving birth. Closely monitoring of AR is warranted in the future in order to optimize mother and child outcomes after delivery.

Suicide in obstructive lung, cardiovascular and oncological disease

Healthcare institutions face increasing demands stemming from the burden of noncommunicable diseases. The personal, social, financial and societal impact of these diseases are well-documented. However, the mental health concerns and trajectories of patients afflicted by chronic medical diseases have been under-recognized and are under-resourced. Despite that chronic diseases are associated with substantially increased risk of suicide, the medical world has largely failed to properly address suicide in the medically ill. Considering their high prevalence and mortality rate, this review article will highlight the mental health burden and suicide risk in obstructive lung, cardiovascular (including stroke) and oncological disease, in light of relevant data and conceptual models of suicide. Finally, general evidence-based suicide intervention strategies and potential selective adaptation of these strategies to the chronic medically ill patient populations and medical settings will be reviewed.

Cumulative evidence for association of rhinitis and depression

Background

Several primary studies evaluated the association between rhinitis and the incidence of depression and yielded inconsistent results. We conducted a meta-analysis of studies evaluating the association between rhinitis and depression.

Methods

We searched the EMBASE, PubMed and Cochrane Library databases for studies published in English before April 1, 2019. The studies were included if they reported any type of rhinitis in relation to depression. Two authors independently extracted the data. The odds ratios (ORs) were pooled using a random-effects model. Stratified analyses were conducted to evaluate the association.

Results

Among the 3472 initially identified studies, we included 14 studies involving a total of 19.36 ± 1.1 million participants according to predefined inclusion criteria. The associations between rhinitis (R), allergic rhinitis (AR), and nonallergic rhinitis (NAR) and depression were significant with ORs of 1.86 (95% CI 1.32 to 2.62, p < 0.05), 1.54 (95% CI 1.24 to 1.90, p < 0.05), and 2.15 (95% CI 1.49 to 3.09, p < 0.05), respectively. The results were consistent and statistically significant in all subgroup analyses.

Conclusions

Rhinitis was associated with an increased risk of depression. Further prospective studies involving large sample sizes are required to confirm the results by considering more confounders and clarify the mechanisms.

Sleep, Fatigue, and Depressive Symptoms among Female Nurses with Allergic Rhinitis

Allergic rhinitis (AR) is a common chronic disease that negatively affects physical and mental health. The purpose of this study was to determine the effects of allergic rhinitis on sleep, fatigue, and depressive symptoms among Korean female nurses. This was a cross-sectional study conducted using data from the Korea Nurses' Health Study (KNHS), and a total of 8645 female nurses was selected for the final analysis. The demographic characteristics, Body Mass Index, alcohol consumption, shift work, comorbidities (atopic dermatitis and asthma), self-rated health, sleep disturbance (Jenkins Sleep Questionnaire), fatigue (Chalder Fatigue Scale), and depressive symptoms (Perceived Health Questionnaire-9) were collected. The data were analyzed using chi-square tests, t-tests, and hierarchical multiple regression analyses. Participants with allergic rhinitis had significantly greater sleep disturbance, fatigue, and depressive symptoms than those without allergic rhinitis, and allergic rhinitis was a significant factor influencing sleep disturbance and fatigue among the participants after controlling for confounding variables. Therefore, it is imperative to develop effective interventions to manage allergic rhinitis symptoms and improve sleep and fatigue in affected nurses.

Anxiety and depression risk in patients with allergic rhinitis: a systematic review and meta-analysis

BACKGROUND

Allergic diseases appear to be associated with mood disorders. However, particularly regarding allergic rhinitis (AR), such association has not been adequately systematically reviewed. Therefore, we conducted a systematic review and meta-analysis to quantify the association between AR and depression and anxiety.

METHODOLOGY

We performed an electronic search of PubMed, Web of Science and Scopus for observational studies assessing the association between AR and depression and anxiety. Such association was quantified by means of random-effects meta-analysis, with estimation of pooled odds ratio (OR). Sources of heterogeneity were explored by subgroup analysis.

RESULTS

We included a total of 24 primary studies, of which 23 assessed depression and 11 assessed anxiety. Of these, 12 studies presented OR from multivariable regression models and were included in our meta-analysis. AR was associated with higher odds of depression and anxiety.

CONCLUSIONS

AR appears to be associated with high risk of depression and anxiety. While our results point to the importance of mental comorbidities among patients with AR, longitudinal studies are needed adopting uniform definitions and presenting results stratified by AR severity.

A study of the association of cognitive abilities and emotional function with allergic disorders in young women

Background

Allergic disorders may have a bidirectional causal relationship with mental disorders. In this cross-sectional study, we aimed to assess the associations between cognitive abilities and emotional function tests and quality of life with the presence of allergic disease in young women.

Methods

A diagnosis of allergic disorders, comprising allergic rhinitis (AR), asthma and atopic dermatitis (AD), was confirmed by a specialist in allergy. The presence and severity of depression, anxiety, stress, insomnia and sleepiness were evaluated using validated questionnaires. Cognitive abilities and quality of life were assessed using standard instruments.

Results

Among 181 female young participants, the prevalence of AR, asthma and AD were 26.5%, 2.8%, and 14.9% respectively. The AR group had higher scores than the non-AR group for depression, anxiety, insomnia, and lower scores for physical and mental health-related quality of life. Moreover, the AD cases had higher scores on the depression and stress scale compared to those without it (p < 0.05). Asthmatic patients also had significantly higher insomnia severity and lower physical health-related quality of life than non-asthmatic.

Conclusion

There was a high prevalence of psychological/psychiatric disorders that included: anxiety, and sleep problems among allergic women, and a reduced quality of life that may be associated with it.

TAK-242 ameliorates olfactory dysfunction in a mouse model of allergic rhinitis by inhibiting neuroinflammation in the olfactory bulb

OBJECTIVE

Olfactory dysfunction (OD) is a common symptom of allergic rhinitis (AR) that can seriously affect patient quality of life; however, the associated pathogenesis remains unclear. This study aimed to explore the relationship between OD and damage of the olfactory bulb (OB) in allergic rhinitis (AR). The therapeutic potential of TAK-242, a selective TLR4 inhibitor, was evaluated for OD.

METHOD

An AR mouse model was established with ovalbumin (OVA) to test the olfactory function of AR mice using the buried food pellet test (BFPT). Mice with OD were intraperitoneally injected with TAK-242 or 1% DMSO (vehicle). Immunohistochemistry was used to detect microglia and astrocyte activation in the OB. TUNNEL staining was performed to detect apoptosis in the OB. Proteins in the TLR4 signaling pathway were detected by Western blot. The level of proinflammatory factor mRNA in the OB was determined by RT-PCR.

RESULT

Neuroinflammation was observed in the OB of the OD group, as evidenced by glial cell activation and increased proinflammatory factor expression. The number of apoptotic cells was significantly increased in the OB of the OD group. The expression of TLR4, MyD88, and p-NF-κBp65 was significantly up-regulated in the OB of the OD group. TAK-242 treatment significantly reduced the level of IL-1β, IL-6, and TNF-α mRNA expression, as well as activation of microglia and astrocytes in the OB tissues.

CONCLUSION

TAK-242 improve olfactory function in AR mice mainly by reducing neuroinflammation and apoptosis in the OB, which may be related to blocking the TLR4/MyD88/NF-κB signaling pathway.

Allergic Rhinitis and Depression: Profile and Proposal

In addition to nasal symptoms, patients with allergic rhinitis (AR) often experience mental and psychological disorders such as depression. Depression not only makes the treatment of AR more difficult and expensive but also poses a serious impact on the patients' daily activities and quality of life, thus bringing additional burden to the families and the society. Here we systematically review the recent research advances in the correlation between AR and depression, analyze the possible causes and mechanisms of depression in AR, summarize the current diagnosis and treatment strategies, and provide our insights into the AR-related depression; in addition, we introduce briefly the basic research status on AR-related depression. We hope that this review article will provide evidence for future studies.

Depressive and anxiety symptomatology among people with asthma or atopic dermatitis: A population-based investigation using the UK Biobank data

The present study investigated the association of depression and anxiety symptomatology (DAS) with asthma and atopic dermatitis (AD) diagnosis during mid-adult years. The study employed data from 502,641 participants in the UK Biobank. Neutrophils to Lymphocytes Ratios (NLRs) of patients with asthma and AD were calculated and evaluated in relation to DAS, measured via the Patient Health Questionnaire-4 (PHQ-4). Age of asthma or AD onset association with DAS were also estimated. Multivariable regression analyses were implemented among participants with asthma or AD, compared to those without these disorders. Out of 58,833 participants with asthma and 13,462 with AD, the prevalence of DAS was 11.7% and 2.7%, respectively. DAS increased among participants with either asthma or AD, being highest within patients having both (β = 0.41, 95% confidence interval (95%CI), 0.34,0.49). NLR showed a linear increase with PHQ scores in asthma patients, (tertile 1, β = 0.30, 95% CI, 0.27,0.34; tertile 2, β = 0.36, 95%CI, 0.32,0.39, and tertile 3, β = 0.43, 95%CI, 0.39,0.46). An inverted U-shaped association was seen between age of asthma onset and PHQ, with the 40-59 age group (β = 0.54, 95%CI, 0.48,0.59) showing the highest risk followed by the 60+ (β = 0.43, 95%CI, 0.34,0.51 and 20-39 groups (β = 0.32, 95%CI, 0.27,0.38). Similar patterns emerged within AD. Asthma and AD were associated with increased DAS during mid-adult years, being strongest among participants reporting both disorders. A dose-response relationship between NLR and DAS was observed. Asthma or AD onset during mid-adult years (40-59) were associated with the highest increment in DAS.

Impact of depressive disorders on quality of life after middle ear surgery in patients with chronic otitis media

Purpose

The aim of this study was to determine whether preoperative depressive symptoms influence health-related quality of life (HRQOL) after middle ear surgery in patients with chronic otitis media (COM).

Methods

This prospective clinical case study was conducted at a tertiary referral center. All 102 patients who had undergone middle ear surgery for COM were assessed clinically and by audiometric testing (pure tone audiometry) in pre- and postoperative settings. Disease-specific HRQOL was assessed by the validated chronic otitis media outcome test 15 (COMOT-15) and the Zurich chronic middle ear inventory (ZCMEI-21). General HRQOL was measured using the short form 36 (SF-36). Depressive symptoms were assessed using the patient health questionnaire (PHQ-D). The Charlson comorbidity index (CCI) was used to classify comorbidities. The middle ear status was determined using the ossiculoplasty outcome parameter staging (OOPS) index.

Results

After middle ear surgery, the total COMOT-15 and ZCMEI-21 scores improved significantly (p < 0.001). General HRQOL (total SF-36 score) was unaffected by surgery (p < 0.05). Patients without elevated depressive symptoms had significantly better total scores for the COMOT-15 (p < 0.01), ZCMEI-21 (p < 0.001), and for SF-36 (p < 0.001) postoperatively. The results of the multiple regression analyses show that, after adjusting for the OOPS, CCI, and hearing improvement, preoperative depressiveness was significantly associated with worse postoperative COMOT-15 and ZCMEI-21 outcome scores (β = 0.425 and β = 0.362, p < 0.001).

Conclusion

Preoperative depressiveness was an essential predictive factor for HRQOL in patients with COM. This should be considered during patient selection to provide more suitable preoperative counseling.

ARIA guideline 2019: treatment of allergic rhinitis in the German health system

Background: The number of patients affected by allergies is increasing worldwide. The resulting allergic diseases are leading to significant costs for health care and social systems. Integrated care pathways are needed to enable comprehensive care within the national health systems. The ARIA (Allergic Rhinitis and its Impact on Asthma) initiative develops internationally applicable guidelines for allergic respiratory diseases. Methods: ARIA serves to improve the care of patients with allergies and chronic respiratory diseases. In collaboration with other international initiatives, national associations and patient organizations in the field of allergies and respiratory diseases, real-life integrated care pathways have been developed for a digitally assisted, integrative, individualized treatment of allergic rhinitis (AR) with comorbid asthma. In the present work, these integrated care pathways have been adapted to the German situation and health system. Results: The present ICP (integrated care pathway) guideline covers key areas of the care of AR patients with and without asthma. It includes the views of patients and other healthcare providers. Discussion: A comprehensive ICP guideline can reflect real-life care better than traditional guideline models.

The 22-Item Sinonasal Outcome Test as a Tool for the Assessment of Quality of Life and Symptom Control in Allergic Rhinitis

Background

The 22-item Sinonasal Outcome Test (SNOT-22) is a validated patient-reported outcome measure for chronic rhinosinusitis and in many circumstances is used in rhinology/otolaryngology clinics to assess sinonasal symptoms in general when a formal diagnosis is not established, although with little support for such usage.

Objective

To assess the utility of the SNOT-22 as a reflection of quality of life (QOL) and symptom control for patients with allergic rhinitis (AR).

Methods

Retrospective review of 353 patients with persistent AR. Each patient completed a SNOT-22, 5-item EuroQol general health-related QOL (EQ-5D) questionnaire (from which the visual analog scale [VAS] was used), and Rhinitis Control Assessment Test (RCAT). In addition, 95 patients also completed these questionnaires 1 to 12 months later.

Results

The SNOT-22 was negatively correlated with the EuroQol 5-dimensional visual analog scale (EQ-5D VAS; r = −.45, 95% confidence interval [CI]: −0.53 to −0.36, P < .001) and RCAT ( r = −.62, 95% CI: −0.68 to −0.55, P < .001), with excellent internal consistency. The SNOT-22 demonstrated responsiveness, with mean change of −5.8 (95% CI: −8.9 to −2.6, P < .001) from pre- to posttreatment. The change in SNOT-22 over the treatment period was correlated with change in EQ-5D VAS ( r = −.28, 95% CI: −0.46 to −0.07, P = .008) and RCAT ( r = −.56, 95% CI: −0.69 to −0.41, P < .001). The minimal clinically important difference was calculated to be between 6 and 11.

Conclusion

The SNOT-22 has utility to assess QOL and symptom control in AR, and it is both reliable and responsive in its application to patients with AR. The SNOT-22 may therefore be a convenient and versatile tool in the clinical assessment of patients with AR.

Purification, Characterization of Two Polysaccharides from Pinelliae Rhizoma Praeparatum Cum Alumine and Their Anti-Inflammatory Effects on Mucus Secretion of Airway Epithelium

Pinelliae Rhizoma Praeparatum cum Alumine (PRPCA) is an important traditional processed herbal medicine mainly used for treating phlegm in China for more than 2000 years. In our previous studies, extraction optimization, characterization, and bioactivities of total polysaccharides from PRPCA were investigated. In this study, further purification of these polysaccharides was performed. Two polysaccharides named neutral fraction of total polysaccharides-II (TPN-II) and acidic fraction of total polysaccharides-II (TPA-II) were obtained by gradient ion-exchange chromatography followed by gel-permeation chromatography. Results of scanning electron microscopy (SEM) analysis in the present study showed that TPN-II had a tight structure with a rough and uneven surface, while TPA-II had a relative homogeneous surface and a loose structure. Further studies indicated that TPN-II was a homosaccharide mainly composed by glucose with a molecular weight of 8.0 kDa. TPA-II was mainly composed of mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose and arabinose in a molar ratio of 2.1, 2.3, 1.7, 10.6, 2.6, 14.2, and 2.5, with a molecular weight of 1250 kDa. The nuclear magnetic resonance (NMR) results indicated that α and β form glycoside bonds existed in TPN-II and TPA-II, and TPN-II was composed of α-glucopyranose. In addition, both purified polysaccharides have significant anti-inflammatory effects on mucus secretion of human airway epithelial NCI-H292 cells without cytotoxicity. Compared with TPN-II, TPA-II exhibited more significant anti-inflammatory effects on lipopolysaccharide (LPS)-induced airway inflammation by regulating levels of interleukin-4 (IL-4) and interferon-γ (IFN-γ) and inhibiting mucus secretion. The results suggest that polysaccharides from PRPCA could be explored as therapeutic agents in treating inflammation and over secretion of mucus in asthma.

Longitudinal improvement in nasal obstruction symptoms of chronic rhinosinusitis directly associates with improvement in mood

PURPOSE

The effects of nasal obstruction in patients with chronic rhinosinusitis (CRS) are associated with depressed mood. We sought to validate this finding by determining whether improvement in nasal obstruction would translate to improvement in depressed mood.

METHODS

This was a prospective observational study of 150 patients undergoing medical management for CRS. Data were collected at two timepoints: enrollment and a subsequent follow-up visit 3-12 months later. Impact of nasal obstruction was measured using the Nasal Obstruction Symptom Evaluation (NOSE) instrument and depressed mood was measured using the 2-item Patient Health Questionnaire (PHQ-2). Sinonasal symptoms associated with CRS were also measured using the 22-item Sinonasal Outcome Test (SNOT-22). Clinical and demographic characteristics were collected. The relationship between changes in PHQ-2 and NOSE scores was determined with correlation and linear regression.

RESULTS

Change in PHQ-2 score was significantly correlated with change in NOSE score (ρ = 0.30, p < 0.001). After controlling for covariates, change in PHQ-2 score was associated with change in NOSE score (adjusted linear regression coefficient [β] = 0.014, 95% CI 0.006-0.022, p = 0.001). We confirmed these relationships, finding that change in PHQ-2 was associated (adjusted β  = 0.037, 95% CI 0.013-0.061, p = 0.003) with change in the nasal subdomain score of the SNOT-22. Improvement in NOSE score by greater than 22 points was predictive of improvement in PHQ-2 score with sensitivity 54.5% and 83.8% specificity (p < 0.001).

CONCLUSION

These results provide evidence that improvements in nasal manifestations/symptoms of CRS translate to significant improvements in mood.

Depression is associated with poor control of symptoms in asthma and rhinitis: A population-based study

BACKGROUND

Although many studies have highlighted the link between asthma/rhinitis and depression, it is still unclear which characteristics of these diseases are associated with the risk of depression. We aimed to explore the relationship between depression and asthma or rhinitis in a representative sample of the Italian general population.

METHODS

The data were collected in GEIRD, an Italian multicenter, population-based, multicase-control study. 2227 participants (age 21-86 years, female 50%) underwent standardized interviews, skin prick and lung function tests, and were divided into cases of current asthma (n = 528), rhinitis without asthma (n = 972), and controls (n = 727). Two specific questions from the Patient Health Questionnaire (PHQ-2) were asked to identify symptoms of depressed mood and anhedonia, which were used as a proxy of major depression disorder.

RESULTS

The prevalence of depression was 16.7%, 11.9%, and 5.1% in subjects with asthma, rhinitis and controls, respectively. Both in asthma and rhinitis, subjects with depression had worse respiratory-health related quality of life and more frequent disease-related symptoms than their non-depressed counterparts. In asthma, depression was associated with poorer disease control. In rhinitis, depression was significantly associated with a disease-related limitations in daily activities and greater risk of symptom exacerbations and prescriptions of medicines for breathing. Cases of rhinitis with depression were less likely to be atopic.

CONCLUSIONS

Our results suggest that rhinitis exacerbations, particularly in non-atopic subjects, and low asthma control are strongly related to the presence of depressed mood in adults from the general population.

Observational study of mental health in asthmatic women during the prenatal and postnatal periods

Objective: We aimed to examine the prevalence and severity of psychological distress of women with asthma in both the prenatal and postnatal periods, and to determine whether asthmatic women with and without mental health problems differ in self-management, medications knowledge, and asthma symptoms.Methods: We assessed spirometry performance and asthma symptoms in 120 women (mean age 29.8 years) before 23 weeks gestation, as part of the Breathing for Life Trial (Trial ID: ACTRN12613000202763). Prenatal depression data was obtained from medical records. At 6 weeks postpartum, we assessed general health, self-reported asthma control, depression symptoms (with the Edinburgh Postnatal Depression Scale) and adaptive functioning (with the Achenbach System of Empirically Based Assessment scales).Results: Twenty percent of our sample reported having a current mental health diagnosis, 14% reported currently receiving mental health care, while 47% reported having received mental health care in the past (and may/may not have received a diagnosis). The sample scored high on the Aggressive Behavior, Avoidant Personality, and Attention Deficit/Hyperactivity scales. Poorer self-reported postnatal asthma control was strongly correlated with elevated somatic complaints, externalizing problems, antisocial personality problems, and greater withdrawal. Prenatal spirometry or asthma severity and control were largely not associated with measures of psychopathology.Conclusions: These findings indicate that pregnant women with asthma frequently report issues with psychopathology during the prenatal and postnatal periods, and that the subjective perception of asthma control may be more related to psychopathology than objective asthma measures. However, due to sample bias, these findings are likely to be understated.

Self-reported asthma diagnosis and mental health: Findings from the Collaborative Psychiatric Epidemiology Surveys

Historically, asthma has had a mixed association with mental health. More research is needed to examine the associations between asthma and specific psychiatric disorders, and whether these associations hold true across racial groups in the general population of the United States. Using the Collaborative Psychiatric Epidemiology Surveys, we examined the associations between lifetime asthma and specific DSM-IV psychiatric disorders, adjusting for sociodemographic characteristics and smoking status. We found that when looking at the entire sample, self-reported diagnosis of asthma was associated with greater odds of reporting mood disorders (AOR: 1.36; 95% CI: 1.05-1.74). Asthma was not significantly associated with total anxiety disorders (AOR 1.25; 95% CI: 0.98-1.60), though it was specifically associated with generalized anxiety disorder. Asthma was associated with greater odds of having alcohol use disorders (AOR: 1.71; 95% CI: 1.24-2.37), but was not associated with total eating disorders (AOR:1.36; 95% CI: 1.17-2.51) (though it was significantly associated with higher odds for binge eating disorder, but lower odds of reporting bulimia). The strength and the significance of the associations between asthma and psychiatric disorders varied when stratified by race, underscoring the importance of examining race as a potential explanation for the mixed findings observed previously in the literature.

Asthma and other allergic diseases in relation to suicidal behavior among South Korean adolescents

OBJECTIVES

Adolescent asthma can be the cause of social and psychological problems. We investigated the association between asthma with other allergic diseases and suicidal risk behavior among South Korean adolescents using nationally representative data.

METHODS

Web-based self-report data from the Korean Youth Risk Behavior Web-Based Survey were used in this study (N = 237,022). Complex sample logistic regression was used to define the relationship between suicidal behavior and asthma (n = 7177), with other allergic diseases [asthma with allergic rhinitis (AR) or asthma with atopic dermatitis (AD) (n = 9720), asthma with AD and AR (n = 4971)].

RESULTS

Participants with asthma and other allergies showed a higher prevalence of substance use, greater sexual experience, greater perceived stress, poorer perceived health, more severe depression, more suicidal ideation, and more suicide attempts than those without allergy. Depression, suicidal ideation, and suicide attempts increased trend in the following order: no asthma, asthma only, asthma with one other allergy (asthma with AD or asthma with AR), and asthma with AD and AR. After adjusting for multiple confounders, the odds ratio for suicidal ideation with asthma and AD and AR was 1.13 [95% confidence interval (CI), 1.06-1.19] and that for suicide attempts was 1.31 (95% CI, 1.20-1.43).

CONCLUSIONS

Adolescent asthma and other allergies were associated with suicidal behavior.
