The present study extends prior work on the association between allergic rhinitis (AR) and common mental disorders by testing three related hypotheses: 1) that AR is associated with increased rates of depression and anxiety disorders in a large insured population, 2) comorbid AR, depression, and anxiety are associated with increased health and mental health expenditures, and 3) allergy treatment moderates the association between increased expenditures and comorbid AR, depression, and anxiety. Data are from MARKETSCAN, a large health care claims database of over 600,000 privately insured persons. Results indicate that AR is associated with higher rates of depression and anxiety disorder. Outpatient health care expenditures were increased by an average annual amount of $207 when AR and anxiety disorder were comorbid and $363 when AR and depression were comorbid. Finally, prescription treatment of AR moderated the increased expenditures associated with comorbidity.

This study explored the effects of environmental and organizational stressors on the health of shiftworkers in a printing company (n = 124). A questionnaire was used to gather data on work history, organizational factors, psychosocial characteristics, medical history, present health, occupational and non-occupational exposures, and lifestyle factors. The perception of environmental and organizational conditions was associated (P < 0.05) with chronic back pain (odds ratio [OR], 1.29), varicose veins (OR, 1.35), allergic rhinitis (OR, 1.27), depression (OR, 1.45), and gastritis (OR, 1.15). Anxiety scores were associated with allergic rhinitis (OR, 1.14) and skin allergy (OR, 1.09). Shiftwork was a significantly risk factor for conjunctivitis (OR, 3.68), depression (OR, 0.23), cardiac arrhythmia (OR, 7.13), and gastritis (OR, 4.38). Other associations included tenure and chronic back pain (OR, 4.89), toluene exposure and skin allergy (OR, 3.76), worksite and conjunctivitis (OR, 7.0), and worksite and dermatitis (OR, 1.24 to 4.95). The number of hours of exercise per week was associated with varicose veins (OR, 4.33), and alcohol intake was associated with cardiac arrhythmia (OR, 6.74).

We present two Japanese cases of involutional lipoatrophy. The first case is that of a 30-year-old woman, who first appeared at our hospital complaining of a localized, well-demarcated depression, approximately 3 x 4 cm in size, normal to slightly erythematous in coloration, on the lateral side of the left upper arm (Fig. 1a). The condition was asymptomatic, and she had noticed this anomaly a month prior to consultation. She received intramuscular injections of corticosteroids of unknown dosage at the affected site for the treatment of allergic rhinitis 4 months prior to her present consultation. The second patient, a 23-year-old woman, appeared at our hospital complaining of a similar macule 4 x 4 cm in size, which she noticed several weeks prior to her most recent consultation. She had no history of injury or injection at the site before the development of the condition (Fig. 1b). She had been under treatment for atopic dermatitis since early childhood and was treated only with topical applications of white petrolatum containing 2% salicylic acid for the past several years. In order to rule out the possibility of acquired partial lipodystrophy associated with localized scleroderma, lupus profundus and the other connective tissue diseases, a histological examination was performed for both patients. Histopathological analysis of the region exhibited a well-defined fat lobule composed of numerous small adipocytes (Fig. 1c) embedded in hyaline connective tissue. Edema and dilated capillaries were noticeable in the subcutaneous tissue surrounding the area. Inflammatory cells were not prominent, although mononuclear cells were observed in both patients. No epidermal change was seen in either patient. Direct and indirect immunofluorescence studies revealed no deposits of immunoreactants in the skin of either patient. Immunohistochemical studies with the antibody against macrophage (anti-CD68 antigen; DAKO.) showed that positive cells were scattered around blood vessels and shrunken lipocytes in the subcutaneous tissues (Fig. 1d). Most of these cells in the fat lobules were also positive for mucin stains such as Alcian blue. No abnormal findings came to light in the ordinary hematological and blood chemistry examinations of both patients. The autoantibody screening tests using antinuclear, anti-DNA, anticentromere, and anti-Scl-70 antibodies were negative in both patients.

There has been a tendency among some clinicians to underestimate the psychological problems of patients with rhinitis. This study assesses the psychological status of allergic rhinitis patients and the influence of type, duration, and severity of rhinitis on the psychiatric evaluation. Forty-one patients with seasonal and perennial allergic rhinitis and 36 healthy control subjects were enrolled in the study. All patients and control subjects were studied through psychological interviews and several psychological tests such as Symptom Checklist-90 (SCL-90), Courtauld Emotional Control Scale, the McMaster Family Assessment Device, and the Satisfaction with Life Scale. Statistically significant differences between patients and controls were observed in all subscales of the SCL-90, particularly in somatization, depression, and general symptom index subscales. Differences between groups were not significant for the other psychological tests. Additionally, differences between seasonal and perennial allergic rhinitis patients were not significant in all questionnaires. Total symptom scores of rhinitis were positively correlated with general symptom index, somatization, interpersonal relationship difficulties subgroups of the SCL-90, whereas negatively correlated with the scores of satisfaction with the life scale. Patients with allergic rhinitis--regardless of type of rhinitis--may develop a group of psychological complaints related to symptom severity. Since the recognition of specific psychiatric disorders can have therapeutic importance, further studies focusing on the associations of these disorders and allergic rhinitis should be conducted.

Few studies have investigated the relationship between cortisol and cognitive functions other than memory in depression. This study investigated daily salivary cortisol patterns (basal cortisol levels at 08:00, 16:00, and 21:00 h and flatness of the diurnal curve) in relation to cognitive speed and memory. Twenty-seven unmedicated outpatients with major depressive disorder (MDD) were compared with 36 healthy controls and with 20 allergic rhinitis patients, to determine whether effects should be ascribed to MDD or to more general disease-related processes. MDD patients were characterised by a flatter diurnal cortisol curve and by reduced cognitive speed. Flatter cortisol curves were associated with cognitive slowness. However, this relationship is unlikely to be causal; after control for depressive symptoms and group membership, flatness of the diurnal cortisol curve was no longer a significant predictor of cognitive slowness. Thus, MDD and related depressive symptoms appeared to be independently associated with altered cortisol secretory patterns and with decrements in cognitive speed.

The aim of this study was to investigate the relationship between allergic rhinitis and personality traits in a nonpsychiatric population of proven allergic status. Subjects were assigned to the allergic group (n = 29) and the nonallergic group (n = 29) on the basis of the medical examination, allergic prick tests, and self-reported allergic status. Analysis of Minnesota Multiphasic Personality Inventory Profile (MMPI) profiles showed that male subjects with allergic rhinitis had significantly higher scores on depression, paranoia, and social introversion. Depression, hypochondriasis, and hysteria scores were significantly higher in female subjects. It may be concluded that patients with allergic rhinitis have poorer psychological function compared with the nonallergic subjects.

Atopic conditions include allergic rhinitis, atopic eczema, allergic conjunctivitis and asthma. Doctors and patients can choose from a variety of antiallergy medications, testifying that no one medication will suffice to treat all symptoms and that each has a different side-effect profile. Antiallergy medications target histamine receptors, as histamine release contributes to the unpleasant symptoms of itching, tearing, runny nose and skin urticaria. The ideal antihistamine would control the symptoms of atopic disease but cause very few side effects. Traditionally, unwanted effects include drowsiness and somnolence due to CNS depression, and digestive tract problems such as loss of appetite, nausea, vomiting and constipation or diarrhea. Some antihistamines also have anticholinergic effects that are mediated by muscarinic receptors. These atropine-like actions, which can affect the cardiovascular system, are sufficiently prominent in some drugs to be manifest during clinical usage. Epinastine hydrochloride minimally penetrates the blood/brain barrier and has almost no effect on the muscarinic receptors. This drug is marketed as having very few CNS-depressant side effects, few drug interactions and gastrointestinal side effects, and a low risk of cardiotoxicity.

Anti-inflammatory effect of desloratadine (DL), including, but not limited to depression of production of IL-4, IL-6 and IL-8, has been shown in several in vitro experiments but only a few in vivo studies refer to this findings. The purpose of our study was to evaluate the influence of DL on levels of IL-4, IL-10, IL-18 and TGF-beta in sera of patients with seasonal allergic rhinitis (SAR). Sixty-nine subjects suffering from SAR with hypersensitivity to grass pollen were included into the evaluation of clinical efficacy of DL (5mg once daily). None of them was taking any H(1) receptor antagonist during the pollen season before inclusion into the study. Samples of peripheral blood were taken before and after 4 weeks of treatment. Levels of cytokines were determined using the ELISA method. The mean level of IL-4 was 0.212+/-0.07pg/ml before and 0.221+/-0.1pg/ml after the treatment (p=0.52); IL-10 5.13+/-3.14 and 4.71+/-0.88 (p=0.69); IL-18 54.45+/-26.09 and 44.80+/-22.42 (p=0.48); TGF beta 949.17+/-401.5 and 955.7+/-391.2 (p=0.97)pg/ml before and after the treatment, respectively. Unless in vitro DL demonstrates not only anti-allergic but also anti-inflammatory activities data from this in vivo study in a group of patients suffering from SAR do not support previous pre-clinical findings.

Although formerly regarded as a nuisance disease, allergic rhinitis (AR) has a considerable effect on quality of life and can have significant consequences if left untreated. The total burden of this disease lies not only in impaired physical and social functioning but also in a financial burden made greater when considering evidence that AR is a possible causal factor in comorbid diseases such as asthma or sinusitis. Compared with matched controls, patients with AR have an approximate twofold increase in medication costs and 1.8-fold the number of visits to health practitioners. Hidden direct costs include the treatment of comorbid asthma, chronic sinusitis, otitis media, upper respiratory infection, and nasal polyposis. Nasal congestion, the most prominent symptom in AR, is associated with sleep-disordered breathing, a condition that can have a profound effect on mental health, including increased psychiatric disorders, depression, anxiety, and alcohol abuse. Furthermore, sleep-disordered breathing in childhood and adolescence is associated with increased disorders of learning performance, behavior, and attention. In the United States, AR results in 3.5 million lost workdays and 2 million lost schooldays annually. Patients struggle to alleviate their misery, frequently self-adjusting their treatment regimen of over-the-counter and prescription medications because of lack of efficacy, deterioration of efficacy, lack of 24-hour relief, and bothersome side effects. Ironically, health care providers overestimate patient satisfaction with therapy. Therefore, improvement in patient-practitioner communication may enhance patient adherence with prescribed regimens.

The rates of depression, anxiety, and sleep disturbance (suicide risk factors) are greater in patients with allergic rhinitis than in the general population. The rate of allergy is also greater in patients with depression. Preliminary data suggest that patients with a history of allergy may have an increased rate of suicide. Clinicians should actively inquire to diagnose allergy in patients with depression and depression in patients with allergy. Spring peaks of suicide are highly replicated, but their origin is poorly understood. Preliminary epidemiologic data suggest that seasonal spring peaks in aeroallergens are associated with seasonal spring peaks in suicide. Our research in Brown Norway rats demonstrates that sensitization and exposure to aeroallergens induces anxiety-like and aggressive behaviors as well as allergy-related helper T-cell type 2 (Th2) cytokine gene expression in the prefrontal cortex. Thus, it is possible that sensitization and exposure to aeroallergens, which peak in spring, may be conducive to seasonal exacerbation of suicide risk factors such as anxiety, depression, hostility/aggression, and sleep disturbance. Connecting allergy with suicide and suicide risk factors adds to previous neurologic literature connecting allergy with migraines and seizure disorders. Our recent report of Th2 (allergy-mediating) cytokine expression in the orbitofrontal cortex of suicide victims should lead to future studies to test the hypothesis that mediators of allergic inflammation in the nasal cavities may result in Th2 cytokine expression in the brain, influencing affect and behavioral modulation. Certain medications used to treat allergy can exacerbate suicide risk factors, potentially worsening suicide risk and even triggering suicide. Systemic (but not topical) corticosteroids have been associated with manic and depressive episodes and mixed mood states. Recently, the US Food and Drug Administration started investigating the possibility that montelukast may trigger suicide. Although this association requires further exploration and confirmation, clinicians should err on the side of caution, inquiring about past suicide attempts; hopelessness; reasons for living; and suicidal ideation, intent, or plan; and referring the patient to a mental health professional for evaluation if appropriate.
