Personality characteristics in chronic and non-chronic allergic conditions

Vaccine hesitancy in patients presenting to a specialized allergy center: clinical relevant sensitizations, impact on mental health and vaccination rates

Introduction

The COVID vaccination program with new types of vaccinations and early reports of allergic reactions to vaccines led to vaccination hesitancy in patients with allergies. In this study, we aimed to characterize patients who present at an allergy center with specific questions regarding risk assessment to COVID vaccines in comparison to regular allergy center patients.

Methods

A total of 50 patient charts of patients with risk assessment for COVID vaccination (COV group) and 50 regular allergy center patients (ALL group) were assessed for documented allergies, comorbidities, total IgE, and tryptase levels and hospital anxiety and depression score (HADS). Skin prick testing (SPT) with additives of COVID vaccines [polyethylene glycol (PEG), polysorbate] were performed if indicated based on medical history.

Results

Patients who presented for examination prior to a possible COVID vaccination were mostly female (86%) and had more frequently reported allergic reactions to drugs in the past, but only in a minor group (28%) were the reactions qualified as anaphylaxis. The group COV patients scored significantly higher in the HADS for anxiety and depression than the regular group ALL patients. The same trend was observed when data were corrected for gender. It is worth noting that patients without any prior contact to COVID vaccines scored comparable regarding anxiety to patients with prior reaction to COVID vaccinations, but significantly higher in the depression score. In 19 patients (38%) who met the indications for SPT for the suspicious contents PEG and Polysorbate 80, the tests did not show a positive result. Furthermore, 84% of patients underwent the prick test, but only 15% of patients who received consultation alone agreed to vaccination at our center. No vaccination-related event was documented in these patients.

Discussion

In conclusion, vaccination hesitancy was frequently elicited by negative experiences with drugs and putative drug allergies. Female patients predominate in this patient group, and the anxiety and depression scores were significantly elevated. Allergological workup, including SPT, led to a high rate of subsequent vaccinations, whereas a discussion with the patients about risks and individualized advice for vaccination without testing only rarely resulted in documented vaccinations.

Psychological profiles of patients with suspected drug allergy

Background

Several studies demonstrate an important association between allergic diseases and patients' psychological characteristics.

Objective

To evaluate any differences in the psychological characteristics of patients studied for suspected drug allergy in comparison with healthy controls. A secondary aim was to assess differences between patients with confirmed versus excluded drug allergy, with respect to the clinical aspects.

Methods

The psychological characteristics of 115 consecutive patients >16 years-old, studied for suspected drug allergy were assessed. They were compared with healthy controls. Four validated questionnaires were used to evaluate anxiety, depression, alexithymia, and personality type.

Results

Eighty-eight patients completed the evaluation: 34 had confirmed drug allergy and 33 excluded. Forty-eight healthy subjects filled the 4 questionnaires. Increased neuroticism was associated with increased odds of belonging to the excluded drug allergy group (odds ratio [OR], 1.374; 95% confidence interval [CI], 1.173–1.609). Increased neuroticism (OR, 1.244; 95% CI, 1.065–1.453) and increased anxiety (OR, 1.210; 95% CI, 1.084–1.351) were associated with increased odds of confirmed drug allergy. However, higher extraversion decreased this likelihood (OR, 0.755; 95% CI, 0.643–0.888). The odds of having confirmed drug allergy was reduced by 79.7% (OR, 0.203; 95% CI, 0.060–0.694) for patients with 2 suspected drugs and by 84.6% (OR, 0.154; 95% CI, 0.029–0.809) for those with ≥3 in comparison to those with only one. Patients with moderate to severe reactions were more likely to have confirmed drug allergy (OR, 4.295; 95% CI, 1.105–16.693) than those with milder manifestations.

Conclusion

Our results highlight that patients with drug allergy have a distinctive psychological profile. Psychological assessment may help to identify patients that would benefit from a targeted intervention.

Family functioning according to clusters of family management styles in Korean families of children with chronic atopic disease: A cross-sectional study

BACKGROUND

Chronic allergic diseases in children are often linked with behavioral problems, poor daily living, negative perceptions of health, and low life satisfaction.

OBJECTIVES

This study aimed to propose clusters of family management styles in the Korean families of children with chronic atopic disease, including allergic asthma, atopic dermatitis, and/or allergic rhinitis and examine the level of family functioning according to these clusters.

DESIGN

Cross-sectional study.

SETTINGS

A university-level hospital in metropolitan Seoul, South Korea.

PARTICIPANTS

Parents of children with chronic atopic disease.

METHODS

This study included 146 participants. The Korean version of the Family Management Measure and the Korean Family Functioning Scale were used to assess family management styles and family functioning, respectively. Data were analyzed using SPSS 24.0 using descriptive statistics, agglomerative hierarchical clustering with Ward's method prior to k-means clustering, k-means clustering analysis, analysis of variance, and chi-squared test.

RESULTS

Four clusters of family management styles were identified as follows: stable-resilient, less committed, parents' mission, and challenging. Among all participants, 19.9%, 30%, 20.6%, and 29.5% belonged to each of these clusters, respectively. The level of family functioning significantly differed between the four clusters, with the stable-resilient cluster having the highest mean level and the challenging cluster having the lowest mean level. Parents' perceived the complexity of self-managing their child's condition as one of the factors differentiating the level of family functioning of each cluster.

CONCLUSIONS

This study identified four clusters of family management styles and showed that each cluster was associated with a different level of family functioning. The unique characteristics of the four clusters may be helpful in providing individualized care and promoting positive family functioning in families with children having chronic atopic disease.

Salivary cortisol responses to acute stress vary between allergic and healthy individuals: the role of plasma oxytocin, emotion regulation strategies, reported stress and anxiety

Numerous studies have demonstrated that acute psychological stress, induced by the Trier Social Stress Test (TSST) paradigm, affects salivary cortisol secretion and self-reported stress measures including anxiety. Allergy has been related to altered cortisol responsiveness and increased stress vulnerability. Here, we investigated acute stress responses and emotion regulation strategies in cohorts of allergic and healthy individuals. Groups of allergics and healthy individuals were subjected to the TSST and experienced levels of stress and anxiety, as well as emotion regulation strategies, were assessed. Cortisol and oxytocin concentrations were measured in saliva or plasma. The present findings confirm earlier results of altered stress responsiveness in allergic individuals. Acute stress by the TSST evoked higher physiological arousal in allergics by means of salivary cortisol secretion. Allergics also scored higher on emotion suppression. However, individuals who were more likely to use reappraisal recovered more efficiently from the cortisol increase. No such effect for reappraisal was found in the healthy population. No differences in self-reported anxiety and stress emerged between the groups. Plasma oxytocin levels prior to the TSST were significantly higher in allergics. Our data corroborate earlier findings on altered stress susceptibility in allergics. Moreover, we identified differences in emotion regulation and oxytocin secretion which should be further explored. Accounting for the emerging global prevalence of allergy, more in-depth research into the experience of stress, coping strategies and stress-related molecules in allergic people is warranted.Short summaryThis study addressed stress experiences and emotion regulation in allergic and non-allergic adults. Allergics scored higher on emotion suppression, had higher pre-stress concentrations of plasma oxytocin and exhibited a stronger salivary cortisol response to stress than healthy people. The research outcomes indicate that allergic individuals cope less efficiently with acute stress but may benefit from adaptive emotion regulation strategies such as reappraisal.

Patients with atopy exhibit reduced cortisol awakening response but not cortisol concentrations during the rest of the day

It has been documented that cortisol release in response to acute stressors is reduced in patients with atopic dermatitis, allergic rhinitis, and other atopic diseases compared to that in healthy subjects. We aimed to test the hypothesis that atopic patients exert reduced salivary cortisol awakening response (CAR) in comparison with healthy subjects. The hypothesis was tested on a stressful and a relax day selected subjectively. Moreover, we evaluated the impact of trait anxiety. The sample consisted of 60 subjects, out of which 28 were patients with atopy and 32 healthy volunteers of both sexes. Saliva samples were collected in the morning to evaluate CAR as well as in the early afternoon and evening to look at cortisol concentrations during the rest of the day. The results showed reduced CAR in atopic patients compared to that in healthy subjects. This effect was modulated by sex with a significant difference observed in males. While CAR was reduced, atopic patients had unchanged cortisol concentrations throughout the day. The evening cortisol was even higher in atopic patients. If the subjects were stratified according to the trait anxiety, no significant differences in CAR between high and low anxiety were observed. No differences in cortisol variables including CAR were observed between the stressful and relax day. In conclusion, this study presents evidence on reduced CAR suggesting an insufficient HPA axis reactivity in atopy. Furthermore, the data in atopic patients demonstrate that reduced HPA axis reactivity does not necessarily mean lower cortisol concentrations throughout the day. This might be of relevance to immune system function and the course of the disease.

Tachykinin upregulation in atopic dermatitis

Context: Atopic dermatitis (AD) is a chronic, inflammatory, itching skin disorder, which may worsen due to stress, depression and anxiety. Tachykinins may be involved in inflammation signaling as well as they may have a role in stress, depression and anxiety. Objective: This study aimed to measure the expression of tachykinin markers, in the skin of patients with AD, and the correlation of these tachykinins with clinical and psychodemographic parameters. Materials and methods: Twenty-eight adult patients with AD were investigated regarding tachykinin expression in skin biopsies, using an immunohistochemical technique. The patients were characterized with clinical and psychodemographic parameters. Results: The number of substance P and neurokinin (NK)A positive nerve fibers, as well as NKA positive mononuclear dermal cells, was increased in lesional compared to non-lesional skin. Interestingly, the depression score and the number of dermal NK-1 receptor (R) positive cells in lesional as well as in non-lesional skin showed a correlation. Conclusion: These findings indicate an upregulation of the tachykinergic system in the inflamed skin of AD.

Nasal response to stress test in healthy subjects: an experimental pilot study

PURPOSE

Stress has been suspected to play a role in rhinitis. The role of stress on nasal patency has been not yet elucidated. The aim was to evaluate the potential effects of stress on nasal patency in healthy subjects.

METHODS

We conducted a prospective pilot study including 12 healthy subjects. Experimental protocol was divided in three periods (pre-task, task and recovery). In the task period, subjects were exposed to the "Trier Social Stress Test" (TSST), a standardized laboratory stressor. Different parameters including Spielberger State Anxiety Inventory (SSAI) score, visual analogic scale (VAS) of nasal patency feeling, heart rate, acoustic rhinometry measurements have been compared between the three different periods. The study population was divided into two groups according to the Spielberger Trait Anxiety Inventory (STAI) score: A "non anxious" group and a "weakly anxious" group.

RESULTS

Seven subjects were in the "non anxious" group and five in the "weakly anxious" group. TSST significantly increased heart rate in all volunteers. SSAI score was significantly increased (p = 0.04) after the task period (36.6 ± 11.3) when compared to the SSAI score in pre-task period (31.9 ± 12.6). VAS score of nasal patency feeling significantly decreased from pre-task to task and recovery periods. Mean minimal cross-sectional areas and mean volumes of the nasal cavities were not significantly different between the three periods, except in "weakly anxious" group, but the small number of subjects does not allow to draw a definite conclusion.

CONCLUSION

We observed that stress influenced the feeling of nasal patency in healthy subjects. However, the objective effects of stress on nasal geometry were globally non-significant except in "weakly anxious" group. This latter result of our pilot study needs to be confirmed in a larger cohort.

Asthma Induction During Development and Adult Lung Function, Behavior and Brain Gene Expression

In developing youth, allergic asthma is the most common chronic condition, with 9%–10% of youth affected. Asthma onset during childhood and adolescence is further associated with other health issues, particularly psychiatric conditions. To understand causal mechanisms by which developmental asthma may lead to altered behavior, brain and health trajectories, we developed a mouse model of developmental allergic asthma. In the current study, we tested for potential long-term effects of developmental asthma on adult lung function and behavior and brain gene expression associated with emotion and stress regulation. We manipulated airway inflammation (AI) and methacholine (MCH)-induced bronchospasm (resulting in labored breathing, LB) in young male and female BALB/cJ mice and measured adult outcomes 3 months after final asthma manipulations. Results indicated that allergen exposure, used to cause AI, and which ended on post-natal day 56 (P56), led to persistent lung AI, mucus buildup and gene expression related to allergic asthma 3 months after final allergen exposure. In addition, at this same age, early allergen exposure led to altered brain gene expression related to stress regulation (prefrontal corticotropin releasing hormone receptor 1, Crhr1 and hippocampal glucocorticoid receptor, GR) and serotonin function (brainstem serotonin transporter, SERT). On the other hand, LB events during development led to altered anxiety-related behavior. Importantly, sex and pre-asthma fear-related behavior (ultrasonic vocalization, USV rates) modulated these adult outcomes. Asthma that develops during childhood/adolescence may have long-term impacts on emotion and stress regulation mechanisms, and these influences may be moderated by sex and pre-asthma temperament.

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.

Blunted cortisol response to psychosocial stress in atopic patients is associated with decrease in salivary alpha-amylase and aldosterone: Focus on sex and menstrual cycle phase

A decreased responsiveness of the hypothalamic-pituitary-adrenocortical axis to stress stimuli in patients with atopy is well documented. The aim of this study was to investigate personality traits, salivary alpha-amylase activity and the aldosterone response to psychosocial stress procedure based on public speech in atopic patients with respect to sex and the menstrual cycle (MC) phase. The study was performed in 106 subjects of both sexes, 53 atopic patients suffering from allergic rhinitis, allergic asthma or atopic dermatitis and 53 age-, sex-, the MC phase- and BMI- matched healthy controls. Substantially attenuated activity of alpha-amylase and reduced secretion of aldosterone during the psychosocial stress were observed in the whole sample of patients with atopy. Higher activity of alpha-amylase observed in the follicular compared to the luteal phase in healthy women was not present in atopic patients. In both males and females, atopy was associated with blunted cortisol response but no changes in the heart rate. Psychological characterization revealed a significantly higher trait anxiety and higher preference for avoidance-oriented coping strategy in female but not male atopic patients. These findings provide evidence that patients with atopy exhibit insufficient alpha-amylase and aldosterone responsiveness to psychosocial stress, thus suggesting decreased sympathetic activity. Potential disturbances in sex hormone status during the MC in female patients with atopy have to be considered in future research. Changes in personality traits were demonstrated in female atopic patients, but not in male patients.

Neuroendocrinology of the skin

The skin is considered the mirror of the soul and is affected by neurohormonal triggers, especially stress. Hair follicles, keratinocytes, mast cells, melanocytes, and sebocytes all express sex and stress hormones implicating them in a local "hypothalamic-pituitary-adrenal axis." In particular, the peptides corticotropin-releasing hormone (CRH) and neurotensin (NT) have synergistic action stimulating mast cells and are uniquely elevated in the serum of patients with skin diseases exacerbated by stress. Addressing the neurohormonal regulation of skin function could lead to new targets for effective treatment of inflammatory skin diseases.

The Microbiota, Immunoregulation, and Mental Health: Implications for Public Health

The hygiene or "Old Friends" hypothesis proposes that the epidemic of inflammatory disease in modern urban societies stems at least in part from reduced exposure to microbes that normally prime mammalian immunoregulatory circuits and suppress inappropriate inflammation. Such diseases include but are not limited to allergies and asthma; we and others have proposed that the markedly reduced exposure to these Old Friends in modern urban societies may also increase vulnerability to neurodevelopmental disorders and stress-related psychiatric disorders, such as anxiety and affective disorders, where data are emerging in support of inflammation as a risk factor. Here, we review recent advances in our understanding of the potential for Old Friends, including environmental microbial inputs, to modify risk for inflammatory disease, with a focus on neurodevelopmental and psychiatric conditions. We highlight potential mechanisms, involving bacterially derived metabolites, bacterial antigens, and helminthic antigens, through which these inputs promote immunoregulation. Though findings are encouraging, significant human subjects' research is required to evaluate the potential impact of Old Friends, including environmental microbial inputs, on biological signatures and clinically meaningful mental health prevention and intervention outcomes.

The associations between personality traits, education, occupation and the occurrence of eczema in adulthood

There were 5834 participants with complete data on parental social class at birth, childhood cognitive ability tests scores at 11 years, educational qualifications at 33 years, the Big Five-Factor personality traits, occupational levels and eczema (measured at age 50 years). Results showed that eczema in childhood, educational achievement and occupational levels were significantly associated with the occurrence of reported eczema in adulthood. Emotionally Stable people (non-neurotic) were less likely to have eczema, but those with high Agreeableness and Openness more likely to have eczema. Childhood cognitive ability was significantly and positively associated with eczema in adulthood.

Parenting and relationship characteristics in mothers with their children having atopic disease

This study compared parental cognitions and relationship characteristics of mothers of children with atopic disease with those of mothers of children without atopic disease. These factors include child-rearing attitudes, parental locus of control, parental sense of competence, attachment security, and maternal sensitivity. Preplanned subanalyses were carried out according to specific disease, mothers' perception of disease severity, and presence of concurrent atopic diseases. The descriptive comparative study of 233 Korean mothers included 102 mothers of children aged six years or younger with atopic dermatitis, asthma, and/or allergic rhinitis. Data were collected from 2007 to 2008 from local clinics and day care centers. Parental cognitions and relationship characteristics did not differ significantly between groups of mothers, except that mothers of children with atopic dermatitis showed less affection. However, subanalyses showed that mothers who perceived their child's disease to be severe were less likely to encourage autonomy and had a lower sense of competence, more rejecting attitudes, and an external locus of control. Although we should be cautious in generalizing these results, special care plans are strongly recommended for mothers of children with severe atopic disease to provide support and education, help mothers develop an internal locus of control, and increase parental sense of competence.

Itch mechanisms and circuits

The itch-scratch reflex serves as a protective mechanism in everyday life. However, chronic persistent itching can be devastating. Despite the clinical importance of the itch sensation, its mechanism remains elusive. In the past decade, substantial progress has been made to uncover the mystery of itching. Here, we review the molecules, cells, and circuits known to mediate the itch sensation, which, coupled with advances in understanding the pathophysiology of chronic itching conditions, will hopefully contribute to the development of new anti-itch therapies.

Mast cells on the mind: new insights and opportunities

Mast cells (MCs) are both sensors and effectors in communication among nervous, vascular, and immune systems. In the brain, they reside on the brain side of the blood-brain barrier (BBB), and interact with neurons, glia, blood vessels, and other hematopoietic cells via their neuroactive prestored and newly synthesized chemicals. They are first responders, acting as catalysts and recruiters to initiate, amplify, and prolong other immune and nervous responses upon activation. MCs both promote deleterious outcomes in brain function and contribute to normative behavioral functioning, particularly cognition and emotionality. New experimental tools enabling isolation of brain MCs, manipulation of MCs or their products, and measurement of MC products in very small brain volumes present unprecedented opportunities for examining these enigmatic cells.

Do patients with allergic rhinitis have a particular personality trait?

OBJECTIVES

This study investigated the personality traits of patients with allergic rhinitis. It also examined the association between personality type and the type of allergic rhinitis, and compared this with the general population.

METHODS

A descriptive observational pilot study was carried out on 50 consecutive cases of allergic rhinitis who presented to the allergy clinic between June and October 2010. These patients were compared with a control group comprising 50 individuals from the general population that had no symptoms of allergic rhinitis. Both groups completed the International Personality Disorder Examination questionnaire for the assessment of personality traits.

RESULTS

Persons falling into cluster C personality type showed a positive correlation with the type and severity of allergic rhinitis. The majority of control group individuals fell into cluster A. This indicated a correlation between allergic rhinitis and a dominant anxious trait compared with the control group.

CONCLUSION

In psycho-allergological research, the potential relevance of personality factors in the maintenance and exacerbation of atopic symptoms is still a matter of debate. More attention should be paid to the psychological status of allergic rhinitis patients, and appropriate treatment should be provided to improve their symptoms and quality of life.

Depression, Anxiety, and Health-Related Quality of Life in Adolescents and Young Adults With Allergies and Asthma

The current study sought to compare rates of depressive symptoms, anxious symptoms, and health-related quality of life (HRQOL) in adolescents and young adults (AYAs) with allergies, asthma, and healthy controls. Participants were undergraduate students aged 18 to 29 years with self-reported allergies (N = 79), asthma (N = 79), and with no history of a chronic illness (N = 79). Participants completed the Center for Epidemiologic Studies Depression Scale, the Zung Self-Rating Anxiety Scale, and the SF-36 Health Survey Questionnaire as self-report measures of depressive symptoms, anxious symptoms, and HRQOL, respectively. A series of ANCOVAs (analysis of covariance; allergies vs asthma vs healthy controls) was conducted to examine differences between the groups. The results of the current examination suggest that AYAs with allergies are indeed at risk for experiencing higher rates of depressive and anxious symptoms and poorer HRQOL than healthy AYAs. Furthermore, they are experiencing psychosocial concerns on par with or worse than those of AYAs with asthma. Allergies, often perceived as a relatively benign illness, have commonly been overlooked in discussions of psychosocial concerns related to chronic illnesses. The results of the current study suggest that young adults with allergies are also an important population to examine.

Allergic rhinitis induces anxiety-like behavior and altered social interaction in rodents

Epidemiological and clinical studies report higher incidences of anxiety and increased emotional reactivity in individuals suffering from respiratory allergies. To evaluate if respiratory allergies are capable of promoting anxiety-like behavior in rodents, we used models of allergic rhinitis and behavioral evaluations followed by assessment of mRNA for cytokines in relevant brain regions. Mice and rats were sensitized to ovoalbumin or pollen, respectively, following standard sensitization and challenge protocols. After challenge, the animals were evaluated in the open field, elevated plus-maze and resident-intruder tests. Cytokines and corticotropin-releasing factor expression were assessed in several brain regions by real-time RT-PCR and plasma corticosterone concentrations by radioimmunoassay. Mice and rats sensitized and exposed to allergen showed increased anxiety-like behavior and reduced social interaction without any overt behavioral signs of sickness. T-helper type 2 (T(H)2) cytokines were induced in both rats and mice in the olfactory bulbs and prefrontal cortex and remained unchanged in the temporal cortex and hypothalamus. The same results were found for CRF mRNA expression. No differences were observed in corticosterone concentrations 1h after the last behavioral test. These results show that sensitization and challenge with allergens induce anxiety across rodent species and that these effects were paralleled by an increased expression of T(H)2 cytokines and CRF in the prefrontal cortex. These studies provide experimental evidence that sensitized rodents experience neuroimmune-mediated anxiety and reduced social interaction associated with allergic rhinitis.
