Impact of allergy treatment on the association between allergies and mood and anxiety in a population sample

The impact of allergies on patient-reported outcomes after total hip and knee arthroplasty: a systematic review and meta-analysis

INTRODUCTION

Metal hypersensitivity has been associated with persistent symptoms after total hip arthroplasty (THA) and total knee arthroplasty (TKA), despite successful joint replacement. Allergies frequently co-occur and have been linked to psychiatric disturbances such as anxiety. There is a knowledge gap regarding the effect of allergies, including metal hypersensitivity, on patient-reported outcome measures (PROMs) after THA and TKA. This study aimed to evaluate the influence of allergies including metal hypersensitivity on PROMs in patients undergoing THA and TKA.

MATERIAL AND METHODS

A systematic search PROSPERO (CRD42023475972) was conducted using PubMed, EMBASE, Scopus, and Cochrane databases. Studies that compared allergic and non-allergic adults undergoing primary THA or TKA and reported PROMs were included. Methodological quality was assessed using the MINORS criteria. The mean differences (MD) and standardized mean differences (SMD) with 95% confidence intervals (CI) were calculated. Eight studies, involving 33,808 patients, were included.

RESULTS

For functional outcomes assessed using SF-12, SF-36, KOOS JR, and HOOS JR, allergic patients demonstrated significantly worse scores (SMD - 0.23, 95% CI -0.36 to -0.09). The WOMAC functional scale also demonstrated poorer results in allergic patients (MD 2.49, 95% CI 0.64 4.35). For pain assessed using the WOMAC pain scale, allergic patients reported significantly greater pain (MD 1.04, 95% CI 0.46 1.62). Changes in mental status assessed using the SF-12 and SF-36 did not show significant differences between the groups (MD -0.46, 95% CI -1.40 to 0.47). In subgroup analysis, patients in the THA subgroup showed significantly worse outcomes (MD -7.20, 95% CI -12.97 - -1.43).

CONCLUSION

This meta-analysis found that patients with allergies, including metal hypersensitivity, generally had worse functional outcomes after THA and TKA than patients without allergies. Further research is required to confirm these findings. Preoperative allergy screening can identify individuals at risk of treatment optimization.

Effects of the immunoglobulin/histamine complex on panic disorder concurrent with chronic spontaneous urticaria: a case report

BACKGROUND

Panic disorder and panic attacks are two of the most common problems in psychiatry. A psychoimmunological correlation between allergic diseases and panic disorder has been strongly suggested. Histamine H1 receptor antagonists have been suggested as alternative drugs for the treatment of panic disorder. Chronic spontaneous urticaria (CSU) and panic disorder improved simultaneously with selective serotonin reuptake inhibitor antidepressants. Panic disorder has also been treated with the antihistamine chlorpheniramine. The immunoglobulin/histamine complex is a histamine-fixed immunoglobulin preparation that was reported to be effective in treating CSU. This case report describes the successful treatment of a patient with concomitant panic disorder and CSU for 23 years using immunoglobulin/histamine complex therapy.

CASE PRESENTATION

This report describes a 52-year-old female Korean patient who suffered from CSU with panic disorder for 23 years. Basic allergy tests (blood tests and skin prick tests) were conducted before and after treatment for the evaluation of allergic conditions. A multiple allergosorbent test (MAST) for the detection of allergen-specific IgE levels was also performed. The clinical severity of CSU was evaluated using the urticaria severity score system. Diagnostic interviews systematically assessed the diagnostic criteria outlined by the DSM-V, and the patient was evaluated before, during and after treatment using the Beck Depression Inventory (BDI-2) for depression, the State-Trait Anxiety Inventory (STAI) for anxiety and the Beck Hopelessness Score (BHS) for hopelessness. The patient received 2 ml of Histobulin™ (12 mg human immunoglobulin/0.15 µg histamine complex) once a week by subcutaneous injection for the treatment of CSU. Initial improvement of CSU was achieved after the third injection. After the twenty-seventh injection of Histobulin™, she showed no symptoms or signs and ceased allergic medication use. With the remission of CSU, allergic rhinitis was also completely resolved. The frequency of the common cold was significantly decreased during and after treatment. The medication frequency and development of clinical manifestations of panic disorder changed in parallel with the clinical severity of CSU. Moreover, the patient exhibited no clinical manifestations and ceased medication for panic disorder and sleeping pills for insomnia simultaneously with the remission of CSU. In the psychological evaluation, the BDI, STAI and BHS scores improved accordingly.

CONCLUSIONS

The immunoglobulin/histamine complex was effective in treating CSU and concomitant panic disorder in this patient and could be effective in treating some types of panic disorder. Considering the mechanisms of action of histamine and the immunoglobulin/histamine complex together with the patient's clinical progress, histamine seemed to be related to panic disorder in this case. The concept of histamine-mediated syndromes, including allergies and psychiatric disorders, shows that a wider disease identity may be needed. Further studies on the immunopathogenesis of panic disorder and the mechanisms of action of the immunoglobulin/histamine complex are necessary.

Structural, functional and behavioral impact of allergic rhinitis on olfactory pathway and prefrontal cortex

BACKGROUND

Allergic rhinitis (AR) has been identified as a cause of olfactory dysfunction. Beyond the classic symptoms, AR has been associated with altered sleep patterns, a decline in cognitive performance and higher likelihood of depression and anxiety. The olfactory pathway has been postulated to be a possible link between nasal inflammation and central nervous system (CNS) modifications. Thus, we aimed to investigate the structural, functional and behavioral changes in the olfactory pathway and related areas in an animal model of AR.

METHODS

AR was induced in adult Wistar rats by ovalbumin sensitization and challenge. Following olfactory and behavioral tests we investigated the synaptic structure of the olfactory bulb (OB), anterior olfactory nuclei (AON), piriform cortex and prefrontal cortex (PFC), by immunofluorescence detection of synaptophysin (Syn) and glutamatergic, GABAergic and dopaminergic neuronal markers.

RESULTS

We detected a significant decrease in Syn in the glomerular layer (GL) of OB and in the PFC of the AR group. Additionally, the optical density of GAD67 and VGLUT2 was reduced in the OB, AON and PFC, compared to controls. The behavioral tests demonstrated olfactory dysfunction and reduced male aggressiveness in AR rats, but we did not find any difference in the cognition and anxiety-like behavior.

CONCLUSIONS

We confirmed olfactory dysfunction in a rat model of AR and we identified modifications in synaptic activity by reduction of Syn optical density in the GL of the OB and in the PFC. This was accompanied by structural changes in glutamatergic and GABAergic activity in essential components of the olfactory pathway and PFC.

Allergic Rhinitis Seasonality, Severity, and Disease Control Influence Anxiety and Depression

OBJECTIVES

Allergic rhinitis (AR) has been associated with anxiety and depression. A possible influence of frequency and intensity of the AR symptoms has remained unclear. Therefore, we evaluated the association between AR, as well as its control, seasonality and severity, and the presence of anxiety and depression.

METHODS

Participants were selected from a preexistent national database and consecutively contacted by phone. AR was classified according to Allergic Rhinitis and its Impact on Asthma. Presence of anxiety and depression was identified by Hospital Anxiety and Depression Scale (HADS), Beck Anxiety Inventory (BAI), and Beck Depression Inventory-II (BDI-II). We built linear regression models assessing the association between any of the assessed anxiety or depression scores and the occurrence, degree of control, seasonality or severity of AR.

RESULTS

We analyzed 115 participants with AR and 38 participants with no respiratory symptoms. Patients with AR presented higher scores of anxiety (HADS: 3.1; 95% confidence interval [CI] = 1.9; 4.3; p < 0.001) and depression (HADS: 3.8; 95% CI = 2.5; 5.0; p < 0.001). Poorer AR control was positively associated with higher prevalence and scores of anxiety (HADS: 3.0; 95% CI = 1.5; 4.5; p < 0.001) and depression (HADS: 1.8; 95% CI = 0.2; 3.4; p = 0.031). Similar results were obtained with BAI and BDI-II scales. A moderate/severe presentation of AR were also related with higher scores of anxiety (HADS: 1.7; 95% CI = 0.1; 3.2; p = 0.040) and depression (HADS: 1.7; 95% CI = 0.1; 3.3; p = 0.037).

CONCLUSION

The presence of AR, a poorer control, and a moderate/severe presentation of the disease were significantly associated with higher scores of anxiety and depression. Thus, it is important to alert to this association to allow a quick diagnosis of AR-associated pathologies. Laryngoscope, 2022.

Allergic Diseases: A Comprehensive Review on Risk Factors, Immunological Mechanisms, Link with COVID-19, Potential Treatments, and Role of Allergen Bioinformatics

The prevalence of allergic diseases is regarded as one of the key challenges in health worldwide. Although the precise mechanisms underlying this rapid increase in prevalence are unknown, emerging evidence suggests that genetic and environmental factors play a significant role. The immune system, microbiota, viruses, and bacteria have all been linked to the onset of allergy disorders in recent years. Avoiding allergen exposure is the best treatment option; however, steroids, antihistamines, and other symptom-relieving drugs are also used. Allergen bioinformatics encompasses both computational tools/methods and allergen-related data resources for managing, archiving, and analyzing allergological data. This study highlights allergy-promoting mechanisms, algorithms, and concepts in allergen bioinformatics, as well as major areas for future research in the field of allergology.

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.

Development of the Child- and Parent-Rated Scales of Food Allergy Anxiety (SOFAA)

BACKGROUND

Anxiety can be excessive and impairing in children with food allergy (FA). There is no accepted condition-specific measure of anxiety for this population.

OBJECTIVE

To evaluate the validity and reliability of new child- and parent-rated measures of FA-related anxiety in youth.

METHODS

Items for the Scale of Food Allergy Anxiety (SOFAA) were developed by a cognitive-behavioral therapist specializing in pediatric anxiety, in consultation with FA medical professionals and parents of children with FA. Dyads (n = 77) of children with FA (aged 8-18 years; 42.9% females) and their parents (95.5% females) completed full versions of the SOFAA (21 items; scored 0-4) via online survey.

RESULTS

The child-rated SOFFA-C mean score was 29.1 ± 18.3; the parent-rated SOFAA-P mean score was 33.9 ± 16.1. Higher scores indicate higher reported anxiety. Coefficient alphas were 0.94 and 0.92. Factor analyses and item-response theory analyses supported the creation of the 14-item SOFAA-C-brief and the 7-item SOFAA-P-brief, accounting for 93% and 79% of total variance, respectively. Correlations revealed strong convergence between child- and parent-report for both the full (r = 0.85) and brief (r = 0.79) versions. Correlations with a generic measure of child anxiety (Screen for Child Anxiety Related Disorders) and the Food Allergy Quality of Life Questionnaire ranged from moderate to strong, whereas those with a generic measure of child eating problems (About Your Child's Eating) were weak to moderate, supporting convergent and divergent validity. Scores of 48 dyads who completed SOFAAs at time 2 (mean, 16.0 days) appeared stable over time, supporting test-retest reliability.

CONCLUSIONS

The 21-item SOFAA-C and SOFAA-P are reliable and valid scales for measuring condition-specific anxiety in youth with FA. As shorter screening measures, the SOFAA-C-brief and the SOFAA-P-brief are also reliable and valid.

Prevalence and Risk Factors of COVID-19 Symptoms among U.S. Adults with Allergies

BACKGROUND

This study sought to evaluate COVID-19 associated physical and mental health symptoms among adults with allergies compared to the general U.S. adult population.

METHODS

Data for these analyses were obtained from the publicly available COVID-19 Household Impact Survey, which provides national and regional statistics about physical health, mental health, economic security, and social dynamics among U.S. adults (ages 18 and older). Data from 20-26 April 2020; 4-10 May 2020; and 30 May-8 June 2020 were included. Our primary outcomes for this analysis were physical and mental health symptoms experienced in the last seven days. The primary predictor was participants' self-report of a physician diagnosis of an allergy.

RESULTS/DISCUSSION

This study included 10,760 participants, of whom 44% self-reported having allergies. Adults with allergies were more likely to report physical symptoms compared to adults without allergies including fever (aOR 1.7, 95% CI 1.44-1.99), cough (aOR 1.9, 95% CI 1.60-2.26), shortness of breath (aOR 2.04, 95% CI 1.71-2.43), and loss of taste or sense of smell (aOR 1.9, 95% CI 1.58-2.28). Adults with allergies were more likely to report feeling nervous (cOR 1.34, 95% CI 1.13, 1.60), depressed (cOR 1.32, 95% CI 1.11-1.57), lonely (cOR 1.23, 95% CI 1.04-1.47), hopeless (cOR 1.44, 95% CI 1.21-1.72), or having physical reactions when thinking about COVID-19 pandemic (cOR 2.01, 95% CI 1.44-2.82), compared to those without allergies. During the COVID-19 pandemic, adults with allergies are more likely to report physical and mental health symptoms compared to individuals without allergies. These findings have important implications for diagnostic and treatment challenges for allergy physicians.

Anxiety is the cause of the worse outcomes of allergic patients after total knee arthroplasty

PURPOSE

The presence of allergies has been proposed as a risk factor for worse outcomes in total knee arthroplasty surgery. The aim of this study is to evaluate if the presence of some psychiatric disorders is more frequent in patients who report allergies and if they could be the main cause for the worse outcomes.

METHODS

A prospective study, including patients undergoing a primary total knee arthroplasty, was designed. In the preoperative visit, all the patients completed a questionnaire about the presence of allergies and also psychiatric tests for anxiety (State-Trait Anxiety Inventory-STAI-), depression (Remission from Depression Questionnaire-RDQ-), somatization disorder (Patient Health Questionnaire-15-PHQ-15-), pain catastrophizing syndrome (Pain Catastrophizing Scale-PCS), and personality disorder (Reduced NEO-Inventory of Five Factors-NEO-FFI-). In the preoperative and at 6 months of follow up, the functional results of the surgery were assessed by the WOMAC, the SF-12, and the KSS scores.

RESULTS

A total of 209 patients was included: 136 (65%) did not have reported allergies and 73 (35%) did report some allergies. The psychiatric questionnaires showed that the presence of anxiety was more prevalent in the group of patients with reported allergies (STAI-T: no allergies 24.08 points vs. allergies 19.18 points, p = 0.039). When comparing the functional outcomes at 6 months of follow up, most of the analyzed scores improved less in the group of patients with reported allergies than in the no allergy-referred group: WOMAC-total score (34.37 vs. 40.10 points, p = 0.023), WOMAC-pain score (6.03 vs. 7.50 points, p = 0.018), WOMAC-function score (22.97 vs. 27.24 points, p = 0.023), KSS-knee score (25.37 vs. 33.79 points, p = 0.002), and SF-12 physical score (7.89 vs. 11.15 points, p = 0.046). The significance of the difference in the outcomes scores in this group was lost after adjusting for anxiety (p > 0.05).

CONCLUSION

Allergies reported by patients are confirmed as a risk factor for worse results after TKA surgery. The relationship with anxiety disorder seems to explain the association between self-reported allergies and sub-optimal outcomes.

Bridging the Gap Between Physical Health and Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a highly complex and heterogeneous developmental disorder that affects how individuals communicate with other people and relate to the world around them. Research and clinical focus on the behavioural and cognitive manifestations of ASD, whilst important, have obscured the recognition that ASD is also commonly associated with a range of physical and mental health conditions. Many physical conditions appear with greater frequency in individuals with ASD compared to non-ASD populations. These can contribute to a worsening of social communication and behaviour, lower quality of life, higher morbidity and premature mortality. We highlight some of the key physical comorbidities affecting the immune and the gastrointestinal systems, metabolism and brain function in ASD. We discuss how healthcare professionals working with individuals with ASD and parents/carers have a duty to recognise their needs in order to improve their overall health and wellbeing, deliver equality in their healthcare experiences and reduce the likelihood of morbidity and early mortality associated with the condition.

Anxiety and depression in adult patients with asthma: the role of asthma control, obesity and allergic sensitization

OBJECTIVE

To determine the frequency of anxiety and depression in adult patients with asthma and to identify factors associated with them.

METHODS

This cross-sectional study included 164 consecutively recruited patients with asthma aged ≥ 18 years. Participants were clinically assessed and the mental state was analyzed through of the Beck Anxiety Inventory (BAI), the Beck Depression Inventory II (BDI-II); the Asthma Control Test (ACT) was measured, and allergic sensitization and respiratory function were also evaluated. Binary logistic regression models to identify the factors related to anxiety or depression were carried out. Complementary, 95% confidence intervals (CI) were estimated.

RESULTS

Anxiety was present in 54.3% of patients (95% CI: 46.6%-61.7%) while depression was found in 50.6% (95% CI: 43.0%-58.2%). Depression increased the odds of anxiety in patients with asthma (OR: 26.00, p < 0.0001), whereas an ACT score ≥ 20 points and allergic asthma were associated with a lower odds than the reference group (OR: 0.29; p = 0.007 and OR: 0.29; p = 0.024, respectively). Depression was associated with anxiety and obesity (OR: 25.33, p < 0.0001 and OR: 3.66; p = 0.014, respectively).

CONCLUSIONS

Overall, more than half of all asthmatic patients suffer from anxiety and depression. Well-controlled asthma and allergic sensitization decreased the likelihood of anxiety, while depression was associated with both obesity and anxiety.

Asthma, atopy and serious psychological distress: prevalence and risk factors among young people in the Melbourne atopy cohort study

Background: While atopic conditions are associated with increased risk of mental health problems, the evidence that a range of allergic conditions are associated with psychological distress in young people is less clear.Methods: We recruited a longitudinal birth cohort study of 620 children with a family history of allergic disease. At the 18-year follow up, atopic sensitization was determined by skin prick testing. Surveys were used to determine psychological distress (Kessler 6), quality of life (SF12), respiratory symptoms and management, presence of current eczema and hay fever. Regression models were used to identify predictors of psychological distress and quality of life, while controlling for potential confounders.Results: Prevalence of serious psychological distress was quite low (n = 22, 5.3%), and there were no associations between psychological distress and current atopic sensitization, symptoms of hay fever, eczema or asthma. Smoking status and lower level of maternal education were associated with lower physical quality of life (SF12 PCS subscale). Psychological distress total score, lower maternal education, smoking, female sex, and current eczema were associated with worse mental quality of life (SF12 MCS subscale).Conclusion: We found relatively low levels of psychological distress in this cohort of young adults, despite a high prevalence of allergic diseases. Positive social factors may serve to buffer psychological distress amongst the cohort accounting for the low prevalence of serious psychological distress observed.

Atopic diseases/diathesis and subsequent ischemic stroke among patients with bipolar disorder: A nationwide longitudinal study

INTRODUCTION

Previous studies have suggested that both bipolar disorder and atopy are associated with an increased risk of stroke. However, the role of atopic diseases/diathesis in the risk of stroke among patients with bipolar disorder remains unclear.

METHODS

Using Taiwan's National Health Insurance Research Database, we selected 55,593 patients with bipolar disorder between 2002 and 2008, divided them into patients with atopic diseases/diathesis (n = 21,050) and patients without atopic diseases/diathesis (n = 34,543), and observed them until the end of 2011. Patients who experienced a stroke during the follow-up period were identified.

RESULTS

Patients with bipolar disorder and atopic diseases/diathesis had an elevated risk of ischemic stroke (hazard ratio [HR]: 1.44, 95% confidence interval [CI]: 1.25-1.59) compared with patients with only bipolar disorder; a dose-dependent relationship was observed between the number of allergic comorbidities and the risk of ischemic stroke (1 atopic disease, HR: 1.30, 95% CI: 1.13-1.49; 2 atopic diseases, HR: 1.59, 95% CI: 1.33-1.91; ≥ 3 atopic diseases, HR: 2.09, 95% CI: 1.50-2.91).The role of atopic diseases in the risk of hemorrhagic stroke among patients with bipolar disorder was nonsignificant (HR: 0.84, 95% CI: 0.64-1.09).

CONCLUSIONS

Patients with bipolar disorder and atopic diseases/diathesis are more prone to ischemic stroke later in life than are those without atopic diseases/diathesis. Further study is required to investigate the underlying mechanism linking atopy, bipolar disorder, and stroke.

Are Self-Reported Medication Allergies Associated With Worse Hip Outcome Scores Prior to Hip Arthroscopy?

PURPOSE

To determine if there are significant differences in preoperative patient-reported outcome (PRO) scores in patients with and without self-reported medication allergies undergoing hip arthroscopy.

METHODS

Consecutive subjects undergoing hip arthroscopy for femoroacetabular impingement (FAI) syndrome by a single surgeon were retrospectively reviewed. PROs were collected within 6 weeks of the date of surgery. PROs included International Hip Outcome Tool (iHOT-12), Hip Outcome Score (HOS), and Short-Form (SF-12) scores. Allergies to medications were self-reported preoperatively within 6 weeks of the date of surgery. Patient demographics were recorded. Bivariate correlations and multivariate regression models were calculated to identify associations with baseline hip outcome scores.

RESULTS

Two hundred twelve subjects were analyzed (56% female, mean age 35.1 ± 13.2 years). Seventy-two subjects (34%) self-reported allergies (range 1-10; 41 subjects had 1 allergy; 14 subjects had 2; 8 subjects had 3; 2 subjects had 4; 7 subjects had 5 or more). The most commonly reported allergies included penicillin (18), sulfa (13), and codeine (11). Female gender was significantly correlated with number of allergies (Pearson correlation coefficient, 0.188; P < .001). SF-12 Mental Component Score (MCS) was significantly correlated with HOS-ADL (Pearson correlation coefficient, 0.389; P < .001), HOS-SSS (Pearson correlation coefficient, 0.251; P < .001), and iHOT-12 (Pearson correlation coefficient, 0.385; P < .001). There was no significant correlation between number of allergies and all hip PROs. In all multivariate models, the SF-12 MCS had the strongest association with HOS-ADL, HOS-SSS, and iHOT-12 (P < .001 for all). Allergies were not significantly associated with any hip PROs.

CONCLUSIONS

In patients undergoing hip arthroscopy for FAI syndrome, self-reported medication allergies are not significantly associated with preoperative patient-reported hip outcome scores.

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

BACKGROUND

Previous studies have suggested that allergic disorders are associated with an increased risk of depression. However, the results are conflicting.

OBJECTIVE

To determine the association between allergic disorders and depression based on large-scale studies.

METHODS

We reviewed relevant articles obtained from PubMed and Embase. Studies were eligible if they reported an association between allergic disorders and depression and provided available data. Study selection, data extraction, and analyses were undertaken. Pooled relative risks (RRs) with 95% confidence intervals (CIs) were calculated.

RESULTS

Of 1,827 studies identified, 51 including more than 2.5 million participants met our inclusion criteria. Overall, the results showed that allergic disorders were associated with a significant increased risk of depression (pooled RR 1.59, 95% CI 1.48-1.71). A higher risk of depression also was observed in patients with asthma (RR 1.59, 95% CI 1.46-1.74) and those with allergic rhinitis (RR 1.57, 95% CI 1.27-1.93). Subgroup analyses were conducted based on sex and age. Children (RR 1.66, 95% CI 1.41-1.96) and adults (RR 1.58, 95% CI 1.44-1.74) with allergic disorders had a higher risk of depression than controls. However, no significant association was found between allergic disorders and risk of depression in male subjects (RR 1.37, 95% CI 0.98-1.91), but a positive association was detected in female subjects (RR 1.65, 95% CI 1.44-1.89).

CONCLUSION

The results from our study showed that allergic disorders significantly increased the risk of depression.

Anxiety and Atopic Disease: Comorbidity in a Youth Mental Health Setting

Anxiety frequently co-occurs with atopic diseases (e.g., allergies) in community samples, although data are limited to community and pediatric medical samples. Little work has examined atopy rates among mental health treatment seeking youth or whether youth with comorbid anxiety and atopy present similarly to non-comorbid youth. Using initial intake data from a University-based specialty youth clinic for anxiety and depressive disorders (n = 189), rates of atopic comorbidity were benchmarked against lifetime prevalence estimates in epidemiological samples. Anxiety severity and parental stress were compared between youth with and without atopy. Results indicated high rates of atopy in the clinical sample (51.3 %) relative to population atopy estimates (34.5 %). Anxious youth with atopy exhibited more overall and generalized anxiety symptoms relative to non-atopic youth (ps < .05); parental stress was comparable between atopic and non-atopic anxious youth. This suggests potentially heightened clinical severity for youth with co-occurring anxiety and atopy.

Rhinitis as an associated factor for anxiety and depression amongst adults

Introduction

Anxiety and depression are frequent disorders of chronic diseases, yet there is no conclusive information to their association with rhinitis.

Objective

The objective is to determine the frequency of anxiety and depression and its possible association to allergic rhinitis (AR) and non-allergic rhinitis (NAR).

Methods

This is a cross-sectional study in which procured subjects with AR (n = 111), NAR (n = 34) and a control group (n = 96) from the university hospital. The presence of anxiety and depression was considered when it reached a score > 13 based on The Beck Anxiety Inventory Test and The Beck Depression Inventory II Test, respectively. The association between AR and NAR with anxiety and depression was adjusted with the Mantel–Haenszel Method and logistic regression.

Results

The frequency for anxiety in AR, NAR and the control group was 45.9%, 52.9%, 10.4%, respectively (p < 0.001); depression frequency was 38.7%, 47.1%, 16.6% (p = 0.0003), respectively. Both AR and NAR were associated to anxiety and depression in women, but not to men. After adjusting the sex: AR was associated to anxiety (OR = 5.7, p < 0.001) and depression (OR = 2.5, p = 0.015), while NAR was also associated to anxiety (OR = 7.8, p < 0.001) and depression (OR = 3.3, p < 0.014). In multivariate analysis it was identified that AR, NAR and the individual's sex (women) were factors associated to anxiety and depression. Results showed that age was only associated to anxiety.

Conclusion

AR and NAR are diseases associated to anxiety and depression, at least in women.

Evaluation of Psychological Score and Quality of Life in Adults with Allergic Rhinitis and Assessment of Related Risk Factors

BACKGROUND

To evaluate quality of life (QoL) and psychological score in adults with allergic rhinitis (AR) and to assess the possible risk factors.

MATERIALS AND METHODS

A total of 110 adult patients with a define diagnosis of AR, who were referred to an outpatient clinic of allergy and immunology, were included in this study. The modified Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) was applied for the evaluation of QoL in these patients. The psychological score was also assessed, using the Esprint-15 questionnaire.

RESULTS

In a total of 110 patients (68 women, 42 men) with the mean±SEM age of 31.92±1.03 years, nasal congestion was the most common symptom (89.1%). Fifty-one (51%) out of 110 AR patients were found to have olfactory dysfunction (OD; hyposmia, 38%; anosmia, 13%). The relationship between nasal congestion and psychological score was significant (P= 0.005). OD had a significant relationship with QoL, as well as the psychological score (P= 0.001 and P= 0.003, respectively). Furthermore, psychological score had a significant relationship with reduction in QoL and sleep impairment (r, +0.654 and r, +0.591, respectively; P< 0.001). Statistical analysis showed that 54.5% of patients had a high psychological score, which was more common in females, although gender differences were not significant.

CONCLUSION

Considering the increasing prevalence of AR and the significant relationship of OD and sleep impairment with QoL and psychological score, early diagnosis and treatment of AR may be important in improving QoL.

Chronology of Onset of Mental Disorders and Physical Diseases in Mental-Physical Comorbidity - A National Representative Survey of Adolescents

Background

The objective was to estimate temporal associations between mental disorders and physical diseases in adolescents with mental-physical comorbidities.

Methods

This article bases upon weighted data (N = 6483) from the National Comorbidity Survey Adolescent Supplement (participant age: 13–18 years), a nationally representative United States cohort. Onset of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition lifetime mental disorders was assessed with the fully structured World Health Organization Composite International Diagnostic Interview, complemented by parent report. Onset of lifetime medical conditions and doctor-diagnosed diseases was assessed by self-report.

Results

The most substantial temporal associations with onset of mental disorders preceding onset of physical diseases included those between affective disorders and arthritis (hazard ratio (HR) = 3.36, 95%-confidence interval (CI) = 1.95 to 5.77) and diseases of the digestive system (HR = 3.39, CI = 2.30 to 5.00), between anxiety disorders and skin diseases (HR = 1.53, CI = 1.21 to 1.94), and between substance use disorders and seasonal allergies (HR = 0.33, CI = 0.17 to 0.63). The most substantial temporal associations with physical diseases preceding mental disorders included those between heart diseases and anxiety disorders (HR = 1.89, CI = 1.41 to 2.52), epilepsy and eating disorders (HR = 6.27, CI = 1.58 to 24.96), and heart diseases and any mental disorder (HR = 1.39, CI = 1.11 to 1.74).

Conclusions

Findings suggest that mental disorders are antecedent risk factors of certain physical diseases in early life, but also vice versa. Our results expand the relevance of mental disorders beyond mental to physical health care, and vice versa, supporting the concept of a more integrated mental-physical health care approach, and open new starting points for early disease prevention and better treatments, with relevance for various medical disciplines.

Degree of anxiety in food allergic children in a tertiary care center

BACKGROUND

The link between internalizing psychiatric disorders, such as anxiety and depression, and allergic diseases has attracted a high level of interest from psychiatrists and immunologists. Recent studies have found increased anxiety in children with asthma, but findings in children with food allergy (FA) have been inconsistent.

OBJECTIVE

It was hypothesized that children with FA would score significantly higher on a standardized anxiety screen than general pediatric (GP) patients but not as high as patients with diagnosed anxiety disorders.

METHODS

A total of 114 patients aged 8 to 16 years (37 with confirmed anxiety disorder from a pediatric psychiatry clinic, 40 with confirmed FA from a pediatric allergy clinic, and 43 well-care patients from a GP clinic) and their mothers completed the Screen for Child Anxiety Related Emotional Disorders (SCARED).

RESULTS

Children and mothers in the allergy group did not report increased levels of anxiety in children on total SCARED scores or subscales compared with children and mothers from the GP group. There was a trend toward increased panic disorder symptoms reported in children by mothers of children in the allergy group, but this finding did not reach statistical significance.

CONCLUSION

Children with FA did not have increased anxiety; however, there was a trend for mothers of children with allergies to report more symptoms of panic disorder in their children. It remains important to screen families for anxiety-related symptoms and refer them to mental health services when indicated.

Association between mental disorders and physical diseases in adolescents from a nationally representative cohort

OBJECTIVE

Pediatric health care and research focus mostly on single morbidities, although the single-disease framework has been challenged. The main objective was to estimate associations between childhood mental disorders and physical diseases.

METHODS

This study is based on weighted data (n = 6482) from the National Comorbidity Survey Replication Adolescent Supplement (age, 13-18 years). Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition lifetime mental disorders were assessed using the fully structured World Health Organization Composite International Diagnostic Interview, complemented by parent report. Lifetime medical conditions and doctor-diagnosed diseases were assessed by adolescent self-report.

RESULTS

Of 6469 participants, 2137 (35.33%) reported at least one mental disorder and one physical disease. The most substantial associations included those between affective disorders and diseases of the digestive system (odds ratio [OR] = 3.46, 95% confidence interval [CI] = 2.28-5.24), anxiety disorders and arthritis (OR = 2.27, CI = 1.34-3.85), anxiety disorders and heart diseases (OR = 2.41, CI = 1.56-3.73), anxiety disorders and diseases of the digestive system (OR = 2.18, CI = 1.35-3.53), and eating disorders and epilepsy/seizures (OR = 5.45, CI = 1.57-18.87). Sociodemographic factors did not account for the association between mental disorders and physical diseases.

CONCLUSIONS

Findings suggest that mental disorders and physical diseases often co-occur in childhood. This association is a major public health challenge, and the child health system needs additional strategies in patient-centered care, research, medical education, health policy, and economics to develop well-coordinated interdisciplinary approaches linking mental and physical care in children.

The Association between Depressive Symptoms and Physical Diseases in Switzerland: A Cross-Sectional General Population Study

OBJECTIVE

To estimate the association between depressive symptoms and physical diseases in Switzerland, as respective findings might inform about future estimates of mental and physical health care costs.

METHODS

A population-based study, using data from the Swiss Health Survey collected by computer-assisted telephone interviews and additional written questionnaires during the year 2007 (n = 18,760) in Switzerland. The multistage stratified random sample included subjects aged 15 years and older, living in a private Swiss household with a telephone connection. Complete data were available for 14,348 subjects (51% of all subjects reached by telephone). Logistic regression analyses were used to estimate the associations between depressive symptoms and any physical disease, or a specific physical disease out of 13 non-communicable physical diseases assessed with a self-report checklist on common physical diseases. Analyses were adjusted for sex, age, education, occupation, and household income.

RESULTS

In the adjusted models, depressive symptoms were associated with arthrosis and arthritis [Odds Ratio (OR) = 1.79, 95% confidence interval (CI) = 1.28-2.50] and any physical disease (OR = 1.67, 95% CI = 1.33-2.10) after controlling for multiple testing.

CONCLUSION

Our findings contribute to a better understanding of the comorbidity of depressive symptoms and arthrosis and arthritis in Switzerland and might have implications for more precise future estimates of mental and physical health care costs.

Twelve-month prevalence, comorbidity and correlates of mental disorders in Germany: the Mental Health Module of the German Health Interview and Examination Survey for Adults (DEGS1-MH)

This paper provides up to date prevalence estimates of mental disorders in Germany derived from a national survey (German Health Interview and Examination Survey for Adults, Mental Health Module [DEGS1-MH]). A nationally representative sample (N = 5318) of the adult (18-79) population was examined by clinically trained interviewers with a modified version of the Composite International Diagnostic Interview (DEGS-CIDI) to assess symptoms, syndromes and diagnoses according to DSM-IV-TR (25 diagnoses covered). Of the participants 27.7% met criteria for at least one mental disorder during the past 12 months, among them 44% with more than one disorder and 22% with three or more diagnoses. Most frequent were anxiety (15.3%), mood (9.3%) and substance use disorders (5.7%). Overall rates for mental disorders were substantially higher in women (33% versus 22% in men), younger age group (18-34: 37% versus 20% in age group 65-79), when living without a partner (37% versus 26% with partnership) or with low (38%) versus high socio-economic status (22%). High degree of urbanization (> 500,000 inhabitants versus < 20,000) was associated with elevated rates of psychotic (5.2% versus 2.5%) and mood disorders (13.9% versus 7.8%). The findings confirm that almost one third of the general population is affected by mental disorders and inform about subsets in the population who are particularly affected.

Stress and anxiety effects on positive skin test responses in young adults with allergic rhinitis

BACKGROUND

Anxiety and psychological stress affect allergy-related immune function. How these relations influence the evaluations of patients with allergic rhinitis is unknown.

OBJECTIVE

To examine whether anxiety and stress exposure affect skin prick test (SPT) responses to common allergens for which patients with atopy showed no prior positive SPT response.

METHODS

Patients with allergic rhinitis, evidenced by clinical history and SPT results, were admitted twice to a hospital research unit for 4 hours. In a crossover design, SPT wheals were assessed before and after the Trier Social Stress Test and then the following morning; for comparison, SPT wheals were assessed before and after a laboratory session without a stressor. Analyses focused on wheal responses for common allergens that tested negative (wheal size <3 mm larger than saline) from SPTs performed at multiple baseline assessments.

RESULTS

After the Trier Social Stress Test, more anxious patients with atopy had a higher incidence of positive SPT reactions to antigens that previously tested negative. Anxiety was unrelated to positive SPT incidence under nonstressful conditions. Based on clinical symptom reports, newly positive SPT reactions after the stressor were apparently corrections of previously false-negative SPT reactions. The SPT wheal responses for allergens previously testing negative were enhanced after a stressor. Histamine (positive control) or saline (negative control) SPT responses were not affected.

CONCLUSION

A laboratory stressor affected allergen SPT responses in more anxious patients with allergic rhinitis. In addition to clinical history, assessment of anxiety and current stress at the time of the SPT may provide valuable information about a patient's allergic status and aid in clinical decision making.
