Abstract
Allergic rhinitis (AR) and urticaria affect a sizable portion of the population worldwide, resulting in reduced quality-of-life and productivity and increased healthcare costs. Fexofenadine (FEX) is a non-sedating second-generation H1 antihistamine with pronounced efficacy and a very good safety profile, used for the treatment of allergic diseases. In addition to its antihistaminic properties, FEX also has anti-inflammatory effects. FEX has a wide therapeutic window and is not associated with any sedative effects, even at higher than recommended doses. There is a need for an integrated management system for AR and urticaria which includes safe and effective treatment options. An ideal anti-allergic formulation should provide fast relief of symptoms and long-lasting effect without drowsiness. Data from randomized clinical trials show that FEX meets these criteria and is an effective treatment option with a favourable safety profile, improving the quality of life of patients suffering from AR and urticaria.

Abstract
Allergic rhinitis (AR) refers to an IgE-mediated inflammation following exposure to allergen. Often deemed as a minor inconvenience rather than a disease, AR impairs the QOL. Medical treatment has a beneficial effect. To evaluate the QOL in patients of AR. Patients of AR with ≥ 18 years age, receiving treatment in our department are included. Pre and Post treatment VAS (Visual Analogue Scale) and RSDI (Rhinosinusitis Disability Index) are compared to know the effect of disease and treatment on QOL. The patients of PAR (Persistent Allergic Rhinitis) had a greater impact on QOL. In PAR, a combination of INCS (Intranasal Corticosteroids) + oral antihistaminics result in significant reduction in VAS & RSDI scores. In IAR (Intermittent Allergic Rhinitis), Oral antihistaminics monotherapy was most effective in reducing itching while Oral antihistaminics + 1 week of intranasal decongestant was most effective in reducing sneezing, running nose and nasal blockage. Oral antihistaminics + LTRA (Leukotriene Receptor Antagonist) was most effective in reducing physical RSDI score. Oral antihistaminics + 1 week of intranasal decongestantwas most effective in reducing functional and emotional RSDI score. Functional RSDI scores had improved much higher than emotional and physical scores. All these observations were statistically significant. AR does affect the QOL while pharmacotherapy helps in improving the overall QOL. Oral antihistaminic alone or in combination with local decongestant/LTRA in IAR cases while INCS + oral antihistaminic in PAR cases are significantly effective in controlling symptom scores and QOL.

Abstract
Allergic rhinitis (AR) is the most common undiagnosed chronic condition in children. Moderate/severe AR symptoms significantly impair quality of life, and cause sleep disruption, absenteeism and decreased productivity. Additionally, untreated AR predisposes children to asthma and other chronic conditions. Although intranasal corticosteroids are the most effective pharmacologic treatment for AR, oral antihistamines are often preferred. First-generation antihistamines may be chosen to relieve AR symptoms as they are inexpensive and widely available; however, they cause sedative and cardiovascular negative effects due to poor receptor selectivity. Therefore, second-generation antihistamines were developed to reduce adverse effects while retaining efficacy. There are fewer clinical trials in children than adults, therefore, efficacy and safety data is limited, particularly in children under 6 years, highlighting the need to generate these data in young children with AR. Fexofenadine, a highly selective second-generation antihistamine, effectively alleviates symptoms of AR, is non-sedating due to decreased blood-brain barrier permeability, and is devoid of cardiovascular side effects. Importantly, fexofenadine relieves the ocular symptoms of allergic conjunctivitis, which occur concomitantly with AR, improving quality of life. Overall, fexofenadine displays a favorable safety profile and results in greater treatment satisfaction in children compared with other second-generation antihistamines. This review aimed to evaluate and compare the safety and efficacy of fexofenadine with other available first- and second-generation antihistamines in children with AR.

Abstract
Background Nighttime problems constitute a significant burden on the quality of life of patients with seasonal allergic rhinitis (SAR). The aim of this study was to evaluate the effectiveness of montelukast on nighttime AR symptoms. Methods In seven multicenter, double-blind, parallel-group trials, nighttime problems were assessed as the nighttime symptoms score (NSS), an average of three individual symptom scores: difficulty going to sleep, nighttime awakening, and nasal congestion on awakening (each rated 0 = none to 3 = severe). Patients (aged 15–82 years) were randomized to receive montelukast, 10 mg (n = 1751), placebo (n = 1557), or the positive control loratadine, 10 mg (n = 1616). Results In a combined analysis, changes from baseline (mean ± SE) in NSS were -0.28 ± 0.01, -0.16 ± 0.01, and —0.24 ± 0.01 for the montelukast, placebo, and loratadine groups, respectively. Difference versus placebo in least-squares mean change from baseline were —0.11 (95% confidence interval, -0.14, -0.08; p ≤ 0.001) for montelukast and -0.09 (-0.12, -0.06; p ≤ 0.001) for loratadine. Strong baseline correlations (R > 0.70; p < 0.001) of NSS and two of its individual symptoms with the sleep domain of the validated Rhinoconjunctivitis Quality of Life Questionnaire support the validity and importance of measuring nighttime morbidity in SAR. Furthermore, a clinically important benefit of montelukast on the nighttime impact of SAR was shown using an analysis anchored on the Patient's Global Evaluation. Conclusion These data underscore the importance of nighttime problems in patients with SAR and the need to treat nighttime symptoms. In these studies, montelukast significantly improved the NSS, a clinically relevant and valid measure in patients with SAR.

Abstract
BACKGROUND A variety of different environmental exposure chambers (EECs) have been used to evaluate treatments for allergic rhinitis. OBJECTIVE To describe and test a system for a homogenous distribution of grass pollen, Phleum Pratense, in an EEC to be used for controlled pollen exposure studies in allergic participants. METHODS A chamber made of stainless steel with completely rounded corners, seating four individuals at a time, was used. Room pressure, temperature, humidity and the air change rate were kept constant throughout the study period. A rotating pipette dispensed a uniform supply of pollen into a turntable's v-shaped grooves. A stainless steel capillary tube sucked the pollens into a venturi throat at which time the pollens were mixed with a high-pressure airstream of compressed high-efficiency particulate arrestance filtered air and then transported to a spreading plate inside the EEC. To achieve uniform concentrations in the EEC, the turntable's rotating speed was continuously adjusted using information from video-coupled feedback and feed forward mechanisms. Pollen levels were detected using standard volumetric air samplers and laser particle counters. The target pollen exposure level was 1000 pollens/m(3) . Twenty-one participants were exposed to pollens in the EEC twice for 210 min. Participants evaluated their symptoms every 30 min using a total nasal symptom score (TNSS) consisting of blocked nose, runny nose, nasal itching and sneezing. RESULTS Across fifteen study days, the average pollen level was 982 pollens/m(3) (SD, 102 pollens/m(3) ). On average, participants experienced a 10% difference in overall pollen levels between their two visits to the EEC. The mean TNSSs rose throughout the exposure period, with a low at baseline of 0.43 (SD, 0.68) to a high of 4.71 (SD, 2.43) just before exiting the EEC. CONCLUSION AND CLINICAL RELEVANCE This EEC provides a reproducible, precise and homogenous distribution of pollens making it suitable for single-centre allergy clinical trials.

Abstract
OBJECTIVE: Guidelines have been published by the Food and Drug Administration (FDA) and the European Agency for the Evaluation of Medicinal Products (EMEA) for the conduct of seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR) studies. These guidelines have differences regarding the duration of such trials: the FDA suggests 2 weeks for SAR and 4 weeks for PAR but the EMEA suggests 2 to 4 weeks for SAR and 6 to 12 weeks for PAR trials. In the interest of global harmonization, it would be desirable to have a uniform duration of such trials so that investigators, internationally, would be able to readily compare results for various types of treatments based on a single standard. Therefore, we performed an evidence-based review to answer the clinical question, What is the optimal duration for SAR and PAR clinical trials? METHODS: We performed a MEDLINE search of the published literature from 1995 to the present. We used appropriate search terms, such as allergic rhinitis, seasonal allergic rhinitis, perennial allergic rhinitis, SAR, and PAR, to identify pertinent articles. These articles were reviewed and graded according to the evidence quality. RESULTS: After an initial screening of more than 300 articles, 138 articles were analyzed thoroughly. No study specifically addressed the question of the optimal duration of SAR or PAR clinical trials. CONCLUSIONS: We conclude that the current FDA (draft) guidelines calling for a study length of 2 weeks for the assessment of drug efficacy for SAR and 4 weeks for the study of drug efficacy in PAR are appropriate and that longer study periods are not likely to add meaningfully to the assessment of drug efficacy.

Abstract
BACKGROUND A recently reported small, out-of-season environmental exposure unit study found nasal filters to be efficacious in preventing seasonal allergic rhinitis (AR). However, nasal filters still need to show efficacy in a natural setting in a regular pollen season. OBJECTIVE We sought to evaluate the efficacy of nasal filters (Rhinix; Rhinix ApS, Aarhus, Denmark) for the prevention of symptoms related to seasonal AR. METHODS The trial was a single-center, randomized (1:1), double-blind, placebo-controlled crossover clinical trial (NCT02108574) conducted over 2 days in the main grass pollen season in June 2014 in Aarhus, Denmark, on 65 adults with proven grass allergy. A total nasal symptom score (TNSS) consisting of blocked nose, runny nose, nasal itching, and sneezing was used to evaluate symptoms. The difference in daily∑ TNSS (the sum of 13 ratings) was the primary outcome measure. The difference in maximum TNSS (highest score, 13 ratings) was also evaluated. RESULTS The nasal filters significantly reduced daily∑ TNSSs (P = .03) and maximum TNSSs (P = .03) compared with placebo. Median relative reductions were 40% for daily∑ TNSSs (P = .02), 43% for maximum TNSSs (P = .004), 83% for daily∑ sneezing (P = .001), 75% for daily∑ watery eyes (P = .02), and 53% for daily∑ runny nose (P = .005) when compared with placebo. The nasal filters were well tolerated, and no serious adverse events were recorded. CONCLUSION Statistically significant and clinically relevant reductions were achieved for the primary outcome measure of daily∑ TNSS, for maximum TNSS and for a subset of individual symptoms. The results support the preventive role of nasal filters for managing seasonal AR.

Abstract
Background It has been well known that pediatric allergic rhinitis was associated with poor performance at school due to attention deficit. However, there were no cohort studies for the effect of treatment of allergic rhinitis on attention performance in pediatric population. Thus, the aim of this study was to investigate whether attention performance was improved after treatment in children with allergic rhinitis. Methods In this ARCO-Kids (Allergic Rhinitis Cohort Study for Kids), consecutive pediatric patients with rhinitis symptoms underwent a skin prick test and computerized comprehensive attention test. According to the skin prick test results, the children were diagnosed as allergic rhinitis or non- allergic rhinitis. All of the patients were regularly followed up and treated with oral medication or intranasal corticosteroid sprays. The comprehensive attention tests consisted of sustained and divided attention tasks. Each of the tasks was assessed by the attention score which was calculated by the number of omission and commission errors. The comprehension attention test was repeated after 1 year. Results A total of 797 children with allergic rhinitis and 239 children with non-allergic rhinitis were included. Initially, the attention scores of omission and commission errors on divided attention task were significantly lower in children with allergic rhinitis than in children with non-allergic rhinitis. After 1 year of treatment, children with allergic rhinitis showed improvement in attention: commission error of sustained (95.6±17.0 vs 97.0±16.6) and divided attention task (99.1±15.8 vs 91.8±23.5). Meanwhile, there was no significant difference of attention scores in children with non-allergic rhinitis. Conclusions Our study showed that management of allergic rhinitis might be associated with improvement of attention.

Abstract
BACKGROUND : Allergic rhinitis (AR) is a common, costly, and troublesome condition, impairing patients' quality of life (QoL), cognitive function, and productivity. Patients with AR report disturbed sleep, fatigue, irritability, and a range of practical problems. However, there is a relative lack of data on how patients with AR perceive their QoL. OBJECTIVE : To better understand how patients perceive AR and their attitudes toward this condition (including QoL) and its treatment options. METHODS : An online and telephone survey of 3635 people identified as having outdoor and indoor allergies, urticaria, and/or pet allergies was performed in 6 countries. RESULTS : The survey confirmed that patients with allergies perceive their symptoms as causing significant disruptions to their daily lives. Respondents were affected for a considerable part of each day, with the most severe symptoms occurring in the morning. The most important desired effect of medication was the restoration of normal breathing, and the most highly rated attributes of the "ideal" AR drug were efficacy, safety, and freedom from undesirable side effects. CONCLUSIONS : The information gathered from allergy sufferers who participated in this survey sheds light on the degree to which people with allergies are affected by their disease and the limitations imposed by associated symptoms.

Abstract
BACKGROUND In Japan, oral antihistamines are frequently used as the initial treatment for seasonal allergic rhinitis (SAR), and intranasal steroids are added when nasal symptoms worsen. This study aimed to evaluate whether starting treatment with fluticasone propionate nasal spray (FP) from the beginning of pollinosis symptoms and adding fexofenadine hydrochloride tablet (FEX) when SAR is aggravated could achieve improved amelioration of nasal symptoms throughout the pollen season in comparison with a treatment that involves starting with FEX and later adding FP. METHODS In this pragmatic, randomized, open-label, parallel-group trial, 51 Japanese cedar pollinosis patients (age, 16-85 years) were randomly divided and administered FP 100 mcg twice daily as an initial drug with FEX 60 mg twice daily as an additional drug and the same treatment in the reverse order. Nasal symptoms were evaluated in a daily dairy using a 4-point scale. The primary outcome was area under curve of the line representing the daily total nasal symptom score in the pollen season on a graph. RESULTS Initial treatment with FP was significantly (P = 0.0015) more effective than initial treatment with FEX in improving the primary outcome. The average daily total nasal symptom score in the initial treatment with FP group was better than that in the initial treatment with FEX group throughout the pollen season. CONCLUSIONS Initiating treatment with FP and adding FEX might lead to improved outcomes for nasal symptoms in comparison with the same drugs administered in the reverse order.

Abstract
Antihistamines have long been a mainstay in the therapy for allergic rhinitis. Many different oral antihistamines are available for use, and they are classified as first generation or second generation based on their pharmacologic properties and side-effect profiles. The recent introduction of intranasal antihistamines has further expanded the role of antihistamines in the treatment of allergic rhinitis. Certain patient populations, such as children and pregnant or lactating women, require special consideration regarding antihistamine choice and dosing as part of rhinitis therapy.

Abstract
BACKGROUND Specific immunotherapy (SIT) is an effective treatment for grass and/or tree pollen-induced severe allergic rhinoconjunctivitis. However, there are limited detailed data on the use of immunotherapy in children in the United Kingdom. OBJECTIVES We audited NHS paediatric practice against current national guidelines to evaluate patient selection, SIT modalities and adverse events (AEs). METHODS Paediatricians offering pollen SIT were identified through the British Society of Allergy and Clinical Immunology Paediatric Allergy Group (BSACI-PAG) and the database of SIT providers compiled for the Royal College of Physicians and Royal College of Pathologists 2010 joint working group. Standardized proformas were returned by 12 of 20 centres (60%), including 12 of 14 centres offering subcutaneous immunotherapy (SCIT) (85%). RESULTS Three hundred and twenty-three children, with mean age 11 years at initiation (69% boys), had undergone 528 SIT cycles (SCIT 31%) over 10 years. Fifty-five percent of all patients had asthma. Among SCIT programmes 24.5% patients had perennial (± seasonal) asthma; 75.6% of asthmatics undertaking SCIT had treatments at BTS/SIGN step 2 or above. AEs occurred frequently (50.4% of all SIT cycles) but were mild. In sublingual immunotherapy (SLIT) treatment, local intraoral immediate reactions were most common (44.9% SLIT cycles), as compared with delayed reactions around the injection site in SCIT (28.3% SCIT cycles). An asthma diagnosis had no impact on the number of cycles with AEs, or the severity reported. Few cycles (2.9%) were discontinued as a result of AE(s). CONCLUSIONS AND CLINICAL RELEVANCE Pollen SIT is available across England, though small numbers of children are being treated. Current national guidelines to exclude asthmatic children in SIT programmes are not being adhered to by most specialist paediatric allergy centres. SCIT and SLIT has been well tolerated. Review of patient selection criteria is needed and may allow greater use of this therapeutic option in appropriate clinical settings.

Abstract
BACKGROUND Allergic rhinitis (AR) is a global health problem because of its increasing impact on economics, society, and the individual's quality of life. This study compares the outcomes and cost of three intranasal therapeutic approaches to the treatment of AR. METHODS This was a retrospective cohort study using propensity scores to achieve balanced cohorts. The study population included patients ≥16 years of age with at least one intranasal prescription claim, without concurrent nasal polyps or sinusitis. Health care use and costs, airway infections, pharmacy costs, and indicators of unsatisfactory treatment (i.e., treatment augmentation or switching) were evaluated in the 1-year follow-up period using a claims database. RESULTS Data from 141,190 patients in intranasal antihistamines (INA) therapy, intranasal steroids (INS) therapy, and intranasal combination therapy (ICT) cohorts were analyzed. The INA cohort showed the lowest rate of change in treatment (switching or augmentation). Switching rates were lowest in the INS therapy cohort, whereas augmentation was lowest in the INA cohort. AR- and asthma-related medication costs were significantly lower in the INA cohort. No differences were observed in airway infections and overall health care costs. Concurrent chronic obstructive pulmonary disorder and asthma were the strongest predictors of health care cost and respiratory infection in the follow-up period. CONCLUSION A change in treatment was noted in ∼⅓ of the entire study population. None of the treatments had a remarkable effect on health care costs or the occurrence of airway infections. The INA treatment cohort had lower AR- and asthma-related medication costs.

Abstract
OBJECTIVE To assess the impact of dry eye disease (DED) on productivity. RESEARCH DESIGN AND METHODS A cross-sectional, web-based survey was administered to 9034 individuals who are part of the Harris Interactive Online dry eye panel. Patients (≥ 18 years of age) were included if they were currently employed, a United States resident, had a patient-reported physician-diagnosed dry eye, and scored 13 or higher on the Ocular Surface Disease Index (OSDI). Work productivity and impairment in daily activity was measured using the validated Work Productivity and Activity Impairment (WPAI) Questionnaire. Comparisons were made across disease severity groups: mild, moderate, severe. RESULTS Reduced productivity while at work was reported by patients in all three severity groups. Patients with moderate (18%) and severe (35%) disease had significantly greater reductions in productivity than patients with mild (11%) disease, P < 0.05. Impairment in ability to perform daily activities was significantly greater among respondents with severe disease (34%) than respondents with moderate (19%) or mild (12%) disease, P < 0.05. CONCLUSION DED is associated with work productivity loss and impairment of daily activities. These results should be interpreted in the context of limitations related to online survey research.

Abstract
BACKGROUND The impairment that pruritic skin diseases have on patient productivity at work, in the classroom, and in daily activities is substantial and needs to be characterized. The objective of this study was to determine how pruritic skin diseases impact patient productivity and quality of life (QOL), in order to improve the measurement of these endpoints to allow the influence of treatment options including sedative and non-sedative antihistamines to be analyzed. METHODS The impact of pruritic skin diseases and the effect of antihistamine therapy on work, classroom, and daily productivity were evaluated using the Work Productivity Assessment Index-Allergy Specific Questionnaire. The intensity of itch and patient QOL were assessed using a visual analogue scale and Skindex-16, respectively. RESULTS Pruritic skin diseases resulted in significant impairment of work, classroom, and daily productivity. The severity of overall work impairment in atopic dermatitis (AD), urticaria, and prurigo was higher than for other diseases analyzed. However, classroom activity was more adversely affected in patients with urticaria relative to other diseases. All pruritic diseases in this study negatively impacted daily activity to a similar degree. Impaired productivity was significantly improved in patients taking non-sedative antihistamines for 1 month, and the improvements correlated with the alleviation of itch and improved QOL. CONCLUSIONS These results indicate that pruritic skin diseases reduce patient productivity at work, in the classroom, and during daily activities, and that non-sedative antihistamines may offer an advantage over sedative antihistamines for alleviating certain negative consequences of these skin diseases.

Abstract
The objective of this review was to present evidence of the relationship between allergic rhinitis and impairment of quality of life. The data sources were original articles, reviews and consensus statements entered into the Medline and LILACS databases between 1997 and 2008. The following search terms were used: 'allergic rhinitis'; 'quality of life'; and 'sleep disorders'. Quality of life is often impaired in patients with allergic rhinitis, due to the classic symptoms of the disease (sneezing, pruritus, rhinorrhea and nasal obstruction). In addition, the pathophysiology of allergic rhinitis often disrupts sleep, leading to fatigue, irritability, memory deficits, daytime sleepiness and depression. The total burden of this disease goes beyond impairment of physical and social functioning. It has also a financial impact, which becomes greater when we consider the evidence that allergic rhinitis is a possible causal factor of comorbidities, such as asthma and sinusitis. Nasal obstruction, the most prominent symptom, is associated with sleep disorders, which can have a profound effect on mental health, learning, behavior and attention. Finally, allergic rhinitis-a chronic condition that affects adults, adolescents and children-is often underdiagnosed or inadequately treated. The deleterious impact that allergic rhinitis-related sleep disorders have on patient capacity to perform activities of daily living is an important component of the morbidity of the disease. With an accurate diagnosis, there are various available treatments that can reduce the burden of allergic rhinitis.

Abstract
OBJECTIVE To determine the validity, reliability and responsiveness of the Work Productivity and Activity Impairment questionnaire in AS (WPAI:SpA). METHODS Baseline and Week-24 data from a randomized, double-blind study of adalimumab in patients with AS were used. Discriminative validity of WPAI:SpA absenteeism, presenteeism, overall work productivity loss and activity impairment scores was assessed relative to patient-reported outcomes: Bath AS Disease Activity Index (BASDAI), AS Quality of Life Questionnaire (ASQOL), Short-Form 36 Health Survey (SF-36), Physical and Mental Component Summaries (PCS and MCS, respectively) and Health Utilities Index Mark 3 (HUI-3). Responsiveness of the WPAI:SpA instrument was assessed for patients meeting the minimum clinically important differences (MCIDs) for ASQOL and BASDAI (i.e. quality of life and clinical responders, respectively) and quantified with standardized response mean (SRM) calculations. RESULTS Of 315 patients, 205 were employed at baseline. Patients with more severe AS (BASDAI > median) showed significantly greater impairment in work and daily activities than patients with lesser disease severity (P < 0.001). This trend was consistent for ASQOL, SF-36 PCS, SF-36 MCS and HUI-3. There were significant differences in WPAI:SpA scores for patients achieving BASDAI clinical response and ASQOL quality of life response vs non-responders. For responders, SRMs were large for work presenteeism, overall work impairment and activity impairment (-0.86 to -1.29 for BASDAI; -0.89 to -1.18 for ASQOL) and small for absenteeism (-0.25 for BASDAI; -0.31 for ASQOL). CONCLUSIONS The WPAI:SpA is a valid, reliable and responsive tool for assessing work productivity for patients with AS.

Abstract
PURPOSE Evaluate work absence, work productivity, and disruption of work, social, and family life among individuals of varying body mass index (BMI) with or at risk for diabetes mellitus. DESIGN Cross-sectional analysis of survey data. SETTING Community-based U.S. population. SUBJECTS Respondents (n = 15,132; n = 7338 working adults) participating in the U.S. Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD) study were stratified by combinations of BMI (i.e., > or = 30 kg/m2 [obese], 25 to 29.9 kg/ m2 [overweight], and < 25 kg/m2 [normal weight]) and diabetes (i.e., type 2 diabetes mellitus [T2DM], type 1 diabetes mellitus [T1DM], and high risk [HR] or low risk [LR] of T2DM). MEASURES Work impairment was measured using the Work Productivity and Activity Impairment Questionnaire: General Health. Disruption in life was measured using the Sheehan Disability Scale. HR was defined as 3 to 5 of the following factors: abdominal obesity, BMI > or = 28 kg/m2, reported diagnosis of "cholesterol problems,"reported diagnosis of "hypertension, "or history of coronary heart disease or stroke. LR was defined as < or = 2 of these factors. RESULTS Percentage of work impairment and proportion with severe disruption of work, family, and social life increased systematically from normal weight to obese (p < .001). Obese individuals had the greatest impairment at work (11%-15% of work time), greatest impairment of daily activities (20 %-34% of time), and greatest overall impairment (11%-15% of time) in the LR, HR, and T2DM groups. Obesity and T2DM were independent predictors of overall work impairment and life disruption (p < .001). Between 5% and 7% of total variance was explained in the regression models with BMI category, diabetes/risk group, age, gender, race, income, and household size as variables. CONCLUSION; Greatest impairment of work and daily activities was evident among obese individuals for all groups.

Abstract
BACKGROUND Symptoms of allergic rhinitis (AR), particularly nasal congestion, can impair quality-of-life (QoL). However, only a modest correlation exists between these symptoms and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) scores, suggesting that both be evaluated for a complete assessment of health. METHODS Subjects with a > or =2-year history of moderate-to-severe AR to dust mite or cat dander were randomized to desloratadine 5 mg/day (n = 293) or placebo/day (n = 291) for 28 days. Primary endpoint was change from baseline in a.m./p.m. nasal congestion score. Secondary outcomes included change from baseline in total nasal symptom score, individual symptom scores and RQLQ scores (completed on days 1, 7, and 28). RESULTS The Allergic Rhinitis and its Impact on Asthma criteria for persistent allergic rhinitis (PER) were fulfilled by 99% of subjects in the placebo arm. Between-treatment difference in a.m./p.m. nasal congestion score, observed from day 8 onward, significantly favored desloratadine (P = 0.0003). Desloratadine significantly improved a.m./p.m. nasal congestion and RQLQ scores after 1 week and at treatment end (P < 0.05). Improvements in 5 of 7 RQLQ domain scores exceeded the minimal important difference. On days 7 and 28, desloratadine was also significantly superior to placebo in mean change from baseline in a.m./p.m. total nasal symptom score and rhinorrhea score (both P < or = 0.01). Symptomatic benefit was primarily driven by improvement in nasal congestion and rhinorrhea. CONCLUSIONS Desloratadine 5 mg/day significantly improved symptoms associated with PER, including nasal congestion, and provided significant improvement in QoL after 1 week of treatment.

Abstract
BACKGROUND Emedastine difumarate, a selective histamine-H1 receptor antagonist and effective antiallergic agent, inhibits various clinical symptoms of allergic rhinitis, allergic conjunctivitis, urticaria, allergic dermatitis, pruritus cutaneous, and prurigo. In addition to greater efficacy than other antihistamines, emedastine difumarate produces no adverse cardiovascular effects and exhibits minimal anticholinergic activity. Moreover, a recent study revealed that the effect of emedastine difumarate on inhibition of histamine-induced collagen synthesis in vitro was greater in dermal fibroblasts than in nasal mucosa fibroblasts. This result indicates that there are tissue-specific effects of emedastine difumarate and that it may be more effective for treating fibrosis in skin than in nasal mucosa. However, the mechanism and role of tissue remodeling is less well established for allergic skin diseases and allergic conjunctivitis, in comparison to respiratory allergic diseases. OBJECTIVE This review outlines the involvement of histamine in the pathogenesis of tissue remodeling in a variety of organs, and presents the evidence for the effect of antihistamines on this process. Furthermore, this review also discusses antihistamines as an intervention strategy in tissue remodeling. METHODS The scientific literature, published abstracts, and selected textbooks were reviewed. RESULTS/CONCLUSION Although additional evidence is required, emerging evidence suggests that emedastine difumarate may be of value in the prevention of excess tissue remodeling in allergic skin inflammation.

Abstract
BACKGROUND Crohn's disease (CD) is a chronic inflammatory bowel disease usually diagnosed in early adult life and characterized by unpredictable flares and debilitating symptoms such as diarrhea, abdominal pain, and fever, which can interfere with a patient's ability to work and perform daily activities. OBJECTIVE The aim of this study was to assess the validity, reliability, and responsiveness of the Work Productivity and Activity Impairment questionnaire in CD (WPAI:CD). METHODS The WPAI:CD was tested in CD patients enrolled in a 26-week randomized clinical trial of cer-tolizumab pegol versus placebo. Discriminative validity of WPAI:CD absenteeism, presenteeism(reduced on-the-job effectiveness), overall work productivity loss (absenteeism + presenteeism), and activity impairment scores was assessed relative to 5 measures of disease severity and health status: CD Activity Index (CDAI), Short Form-36 physical component summary (PCS) and mental health component summary (MCS) scores, Inflammatory Bowel Disease Questionnaire (IBDQ), and the 5-dimensional EuroQoL health-related quality-of-life visual analog scale (EQ-VAS). Responsiveness was assessed by comparing changes in WPAI:CD scores from baseline to week 26 for patients in remission (CDAI <150 points) versus no remission. Standardized Response Means (SRMs) were calculated to evaluate the magnitude of the changes. RESULTS A total of 662 patients (mean [range] age, 37.4 [18-77] years; male, 288 [43.5%]; white, 629 [95.0%]) were enrolled in the study. Patients with CD of the worst severity (CDAI > median) showed significantly higher impairment in work (+10.5%) and activities (+10.4%) versus patients with "best health" (no problems) (both, P < or = 0.001). Patients with "worst" IBDQ, PCS, MCS, and EQ-VAS scores also showed significantly higher impairments in work (IBDQ, VAS -24.2%; PCS, -24.1%; MCS, -15.9%; EQ-VAS, -16.5%) and activities (IBDQ, -23.3%; PCS, -21.8%; MCS, -16.5%; EQ-VAS, -17.2%) versus "best" scores (all, P < 0.05). There were significant differences between WPAI:CD impairment scores for patients in remission versus patients failing to achieve remission (P < 0.05). SRMs were small (ie, <0.5) in the nonre-mission group, and moderate to large (ie, >0.5) for patients in remission. CONCLUSIONS The discriminative validity, reliability, and responsiveness of the WPAI:CD were demonstrated. The WPAI:CD may be useful for evaluating drug impact on CD.

Abstract
Bipolar disorder (BD) adversely affects daily activities/functioning. The Sheehan Disability Scale (SDS) assesses disability in work/school activities, family relationships, and social functioning, and it evaluates the functional impact of psychiatric disorders. BD outpatients from 21 U.S. sites completed a battery of validated instruments (including the SDS) three times over 8-12 weeks. Instrument reliability (internal consistency, test-retest), validity (construct, convergent validity, known groups) and responsiveness were measured. There were missing data for the SDS in 2% of the 225 subjects with BD. One factor explained 82% of the variance. All SDS items had rotated factor loadings on the first factor >0.90, confirming the appropriateness of the SDS total score. Item-scale correlations surpassed 0.40. There was excellent internal consistency reliability for the SDS total score (Cronbach's alpha=0.89). Test-retest reliability was acceptable for the SDS total score (intraclass correlation coefficient=0.73). Correlations with other instruments demonstrate convergent and divergent validity. The SDS total and item scores significantly discriminated between (self-rated) overall health status, clinician-rated functional status, and clinician-rated depression, evidencing known group validity. The SDS demonstrated ability to detect change over time. The SDS is a valid, reliable measure of disability and is responsive to change over time when used in subjects with BD.

Abstract
BACKGROUND Guidelines recommend treatment with intranasal corticosteroids for patients with allergic rhinitis (AR), but concerns remain about possible adverse effects. OBJECTIVE To present the 1- and 2-year growth results for children with AR treated with triamcinolone acetonide aqueous nasal spray. METHODS Thirty-nine children (aged 6.1-14.3 years at study entry) were treated with triamcinolone acetonide aqueous for 1 year, and a subset of 30 children completed a second year of treatment. The dose was physician titered to achieve control over AR symptoms. For each child, statural heights at baseline and at the 1- and 2-year (where available) visits, together with growth rates, were measured and were compared with predicted values. RESULTS There were no significant differences between measured and predicted heights at the 1- and 2-year visits. The mean (SD) measured--predicted difference was 0.3 (2.2) cm (95% confidence interval, -0.4 to 1.0 cm) at the 1-year visit and 0.5 (3.0) cm (95% confidence interval, -0.6 to 1.6 cm) at the 2-year visit. Mean differences in measured and predicted growth rates were nonsignificant at the 1- and 2-year visits. CONCLUSIONS Triamcinolone acetonide aqueous titered to control AR symptoms and given for 1 or 2 years had no significant effect on statural growth in children with AR.

Abstract
Allergic diseases constitute a global health problem, as they have an increasing economic and social impact and, especially, they can deeply interfere with the patients' daily life, being a cause of physical and emotional discomfort. This is why the health-related quality-of-life (HRQoL) has become increasingly important in health care research; in fact, the assessment of the impact the disease and its treatment have on patients, provides a more comprehensive approach in outcome evaluation. Numerous validated questionnaires are available and many studies have been performed evaluating HRQoL in people affected by allergic rhinitis (AR), thus testifying a great interest in this topic. The aims of the present review are: to examine the scientific literature of the last 3 years dealing with the impact of AR treatments suggested by allergic rhinitis and its impact on asthma guidelines on patients' QoL, and to identify the unexplored or not-fully-investigated areas concerning this issue.

Abstract
BACKGROUND The safety of fexofenadine has been examined extensively in adults and school-age children. However, the safety of fexofenadine in children younger than 6 years has not been reported to date. OBJECTIVE To compare the safety and tolerability of twice-daily fexofenadine hydrochloride, 30 mg, and placebo in preschool children aged 2 to 5 years with allergic rhinitis. METHODS This was a multicenter, double-blind, randomized, placebo-controlled, parallel-group study, conducted between February 29, 2000, and June 14, 2001. Participants were randomized to either fexofenadine hydrochloride, 30 mg, or placebo twice daily for a 2-week period. To facilitate dosing, capsule content was mixed with applesauce (approximately 10 mL). Safety assessments depended on date of entry into the study because of an amendment to the protocol. Before the amendment, assessments included physical examination, vital signs reporting (oral temperature, heart rate, and respiratory rate), and adverse event (AE) reporting. After the amendment, safety assessments included laboratory testing (blood chemistry and hematology profiles), physical examination, 12-lead electrocardiography, and vital signs (oral temperature, blood pressure, heart rate, and respiratory rate) and AE reporting. RESULTS Treatment-emergent AEs were observed in 116 of 231 participants receiving placebo and 111 of 222 receiving fexofenadine. These AEs were possibly related to study medication in 19 (8.2%) and 21 (9.5%) of the participants receiving placebo and fexofenadine, respectively, and most frequently involved the digestive system. No clinically relevant differences in laboratory measures, vital signs, and physical examinations were observed. CONCLUSIONS The findings show that fexofenadine hydrochloride, 30 mg, is well tolerated and has a good safety profile in children aged 2 to 5 years with allergic rhinitis.

Abstract
Quality of life (QoL) or, rather, health-related QoL, is currently regarded as a crucial aspect of the general well-being of patients and, in consequence, of the effects of a disease and its treatment. This is particularly true for respiratory allergy (asthma and rhinitis), which are chronic diseases and also for sinusitis (rhinosinusitis). A number of questionnaires (instruments), either generic or specific, have been developed and validated to assess the QoL in adults and children, for asthma and rhinitis, whereas there are few specific instruments for chronic rhinosinusitis. The literature provides strong evidence of the effects of allergic rhinitis, asthma and their treatments on QoL in paediatric patients, as well as in adults, whereas the number of experimental data on rhinosinusitis is limited, especially in children. Clinical trials evidenced some controversial points, mainly the weak correlation existing between QoL and traditional objective parameters. It has become clear that the QoL questionnaires measure the aspects of the disease that partially differ from the routinely evaluated parameters and that QoL should integrate, not replace, the objective measurements.

Abstract
INTRODUCTION Many employers focus on their large and easily measured cost of health care, yet until recently they have ignored the impact of health on productivity. Studies of some chronic conditions and some health risk factors suggest that costs of lost productivity exceed costs of medical care. This review will examine the literature to explore the link between employee health and on-the-job productivity, also known as presenteeism. METHODS Searches of Medline, CINAHL and PubMed were conducted in October 2006, with no starting date limitation with "presenteeism" or "work limitations" as keywords. A total of 113 studies were found using this method. Each study was evaluated based on the strength of the study design, statistical analyses, outcome measurement, and controlling of confounding variables. RESULTS Literature on presenteeism has investigated its link with a large number of health risks and health conditions ranging from exercise and weight to allergies and irritable bowel syndrome. As expected, the research on some topic areas is stronger than others. CONCLUSIONS Based on the research reviewed here, it can be said with confidence that health conditions such as allergies and arthritis are associated with presenteeism. Moreover, health risks traditionally measured by a health risk appraisal (HRA), especially physical activity and body weight, also show an association with presenteeism. The next step for researchers is to tease out the impact of individual health risks or combinations of risks and health conditions on this important outcome measure.

Abstract
OBJECTIVE The American Academy of Otolaryngic Allergy (AAOA) convened an expert, multidisciplinary Working Group on Allergic Rhinitis to discuss patients' self-treatment behaviors and how health care providers approach and treat the condition. PROCEDURES AND DATA SOURCES: Co-moderators, who were chosen by the AAOA Board of Directors, were responsible for initial agenda development and selection of presenters and participants, based on their expertise in diagnosis and treatment of allergic rhinitis. Each presenter performed a literature search from which a presentation was developed, portions of which were utilized in developing this review article. SUMMARY OF FINDINGS Allergic rhinitis is a common chronic condition that has a significant negative impact on general health, co-morbid illnesses, productivity, and quality of life. Treatment of allergic rhinitis includes avoidance of allergens, immunotherapy, and/or pharmacotherapy (ie, antihistamines, decongestants, corticosteroids, mast cell stabilizers, anti-leukotriene agents, anticholinergics). Despite abundant treatment options, 60% of all allergic rhinitis patients in an Asthma and Allergy Foundation of America survey responded that they are "very interested" in finding a new medication and 25% are "constantly" trying different medications to find one that "works." Those who were dissatisfied also said their health care provider does not understand their allergy treatment needs and does not take their allergy symptoms seriously. Dissatisfaction leads to decreased compliance and an increased reliance on multiple agents and over-the-counter products. Furthermore, a lack of effective communication between health care provider and patient leads to poor disease control, noncompliance, and unhappiness in a significant portion of patients. CONCLUSIONS Health care providers must gain a greater understanding of patient expectations to increase medication compliance and patient satisfaction and confidence.

Abstract
OBJECTIVE To review the results of studies that have evaluated the impact of allergic diseases on patients' health-related quality of life (HRQL). DATA SOURCES We performed a MEDLINE search of the literature published between January 1990 and May 2006 (English language only) on HRQL and allergic diseases. STUDY SELECTION Representative studies that used validated questionnaires that assessed the effect of allergic diseases on HRQL were selected for inclusion in this review. RESULTS Allergic diseases can deeply interfere with patients' HRQL, with detrimental effects on the physical, psychological, and social dimensions of life. Numerous validated questionnaires that are now available can easily be adopted; most of them are specifically developed for rhinitis and asthma. CONCLUSIONS HRQL has become an increasingly important aspect in outcome evaluation in health care research, providing a more comprehensive approach to the patient and proving that nowadays we cannot renounce this tool. Most of the studies evaluate patients with respiratory allergy. Further studies are needed to explore HRQL in other allergic conditions (urticaria, food allergy, sting allergy, drug allergy) by means of specific, validated questionnaires.

Abstract
The effect of sublingual immunotherapy on quality of life (QoL) was examined in patients with grass pollen-induced rhinoconjunctivitis. Patients (n = 855) were randomised to once-daily grass allergen tablets (2,500; 25,000; or 75,000 SQ-T Phleum pratense extract; GRAZAX or placebo. Treatment was initiated 8 weeks before the start of the grass pollen season and continued throughout. If symptoms were present, patients received loratadine or placebo rescue medication. There were three major findings: in patients using loratadine, grass allergen tablets provided QOL benefits over placebo; Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) score was 17% (p = 0.006) and 20% (p = 0.020) greater with 75,000 SQ-T tablet than with placebo at first and second seasonal visit, respectively; in patients not using loratadine, grass allergen tablets improved QoL more than placebo; RQLQ score was 21% greater (p = 0.021) with 75,000 SQ-T tablet at second seasonal visit; grass tablets (without loratadine) had a greater effect on QoL than loratadine alone. RQLQ score was 26% (p = 0.014) greater with 75,000 SQ-T tablets than loratadine at second seasonal visit. These data show that sublingual immunotherapy with grass allergen tablets improves QOL in allergic rhinoconjunctivitis, reduces symptoms, and that this effect is greater than rescue antihistamine alone.

Abstract
BACKGROUND Gastro-oesophageal reflux disease has wide-ranging effects on patients' lives. AIM To review systematically the effects of gastro-oesophageal reflux disease on work productivity. METHODS Studies of gastro-oesophageal reflux disease and work productivity were identified in a systematic literature search and their results were valued in US dollars using the human capital method. Work productivity loss was defined as absence from work (absenteeism) plus reduced effectiveness while working (presenteeism). RESULTS Eight eligible studies were included. Reported work productivity loss among individuals with gastro-oesophageal reflux disease ranged from 6% to 42% and was primarily because of presenteeism (6-40%) rather than absenteeism (<1% to 7%). Reported losses were greatest in patients experiencing sleep disturbance because of gastro-oesophageal reflux disease, and lowest in individuals from the general population taking appropriate prescription medication. Work productivity impairment correlated with symptom severity and responded to acid-suppressive therapy. Assuming a 40-h working week and average wages in the US, the weekly mean productivity loss per employee with gastro-oesophageal reflux disease can be estimated between 2.4 (62 dollars) and 16.6 h (430 dollars), depending on the population studied. CONCLUSIONS Gastro-oesophageal reflux disease has a substantial impact on employee productivity, primarily by impairing productivity while working. Further studies are needed to confirm that this impact can be decreased by acid-suppressive therapy.

Abstract
RATIONALE First- and second-generation antihistamines are known to produce different degrees of sedation. However, a few studies have shown that the H1-antagonist fexofenadine produces mild stimulating effects. One hypothesis suggests that this is due to fexofenadine producing an increase in dopamine levels by blocking the dopamine transporter. OBJECTIVE In this study, it was investigated whether a high dose of fexofenadine blocks the dopamine transporter in the striatum. In addition, the effect of fexofenadine on cognitive performance and motor impulsivity was investigated. METHODS Sixteen healthy subjects were given either placebo or fexofenadine 360 mg. The binding potential of N-w-fluoropropyl-2beta-carbomethoxy-3beta-[4-iodophenyl] nortropane ([123I]FP-CIT) was measured using single-photon emission computed tomography (SPECT). Cognitive performance was measured in 40 subjects (20 placebo, 20 fexofenadine) using a digit symbol substitution test (DSST) and a stop signal task. In addition, subjective and physiological effects of fexofenadine were observed. RESULTS The SPECT data demonstrated that there was no difference in the binding potential of FP-CIT at the dopamine transporter in the striatum between the placebo- and fexofenadine-treated subjects. The behavioral results showed that fexofenadine improved performance on the DSST at T (max) of the drug. Fexofenadine did not affect motor impulsivity, subjective experience, or physiological measures. CONCLUSION No evidence was provided to support the hypothesis that fexofenadine stimulates performance by blocking the dopamine transporter. The behavioral data suggest that a high dose of fexofenadine can stimulate performance in cognitive tasks.

Abstract
INTRODUCTION There are no measures of health-related absenteeism and presenteeism validated for use in the large and increasing US Spanish-speaking population. Before using a Spanish translation of an available English-language questionnaire, the linguistic validity of the Spanish version must be established to ensure its conceptual equivalence to the original and its cultural appropriateness. OBJECTIVE The objective of this study was to evaluate the linguistic validity of the US Spanish version of the Work Productivity and Activity Impairment questionnaire, General Health Version (WPAI:GH). METHODS A US Spanish translation of the US English WPAI:GH was created through a reiterative process of creating harmonized forward and back translations by independent translators. Spanish-speaking and English-speaking subjects residing in the US self-administered the WPAI:GH in their primary language and were subsequently debriefed by a bilingual (Spanish-English) interviewer. RESULTS US Spanish subjects (N = 31) and English subjects (N = 35), stratified equally by educational level, with and without a high school degree participated in the study. The WPAI-GH item comprehension rate was 98.6% for Spanish and 99.6% for English. Response revision rates during debriefing were 1.6% for Spanish and 0.5% for English. Responses to hypothetical scenarios indicated that both language versions adequately differentiate sick time taken for health and non-health reasons and between absenteeism and presenteeism. CONCLUSION Linguistic validity of the US Spanish translation of the WPAI:GH was established among a diverse US Spanish-speaking population, including those with minimal education.

Abstract
BACKGROUND To date, it is unknown whether fexofenadine mitigates the worsening of symptoms induced by the cat allergen Felis domesticus allergen 1. OBJECTIVE To determine the effects of a single dose of fexofenadine hydrochloride, 180 mg, in preventing and controlling cat allergen-induced allergic rhinitis symptoms using the cat room challenge model. METHODS This single-center, randomized, double-blind, placebo-controlled, 2-way crossover study consisted of a screening visit, 1 or 2 qualifying visits, and 2 treatment periods separated by a mean +/- SD washout period of 14 +/- 3 days. Patients were randomized to treatment sequence 1 (placebo followed by fexofenadine) or sequence 2 (fexofenadine followed by placebo). Baseline end points were obtained before study drug administration, and allergen challenges were initiated 1 1/2 hours after dosing. The primary end point was the change from predose baseline in the total symptom score (sum of rhinorrhea, itchy nose/palate/ throat, sneezing, and itchy/watery/red eyes) after 30 minutes of allergen exposure compared with placebo. RESULTS Of 211 patients screened, 66 were randomized and 63 completed the study. Mean change in the total symptom score from predose baseline was significantly less with fexofenadine compared with placebo 30 minutes after initiation of the cat allergen challenge (2 hours after dosing) (P = .03). The overall incidence of treatment-emergent adverse events was low and comparable for both groups. CONCLUSION Prophylactic treatment with a single dose of fexofenadine hydrochloride, 180 mg, significantly mitigated the worsening of allergic rhinitis symptoms induced by exposure to cat allergen compared with placebo use.

Abstract
Allergic rhinitis is a common medical condition characterized by nasal, throat, and ocular itching; rhinorrhea; sneezing; nasal congestion; and, less frequently, cough. The treatment of allergic rhinitis should control these symptoms without adversely affecting daily activities or cognitive performance and should prevent sequelae such as asthma exacerbation or sinusitis. This review describes a stepwise approach to treatment of allergic rhinitis derived from a synthesis of clinical trial results, patient preferences, and real-world tolerability data. Key clinical considerations include frequency and intensity of symptoms, patient age, comorbidities, compliance with treatment regimens (influenced by formulation, route and frequency of administration), and effects on quality of life. Oral second-generation antihistamines, versus first-generation agents and inhaled corticosteroids, should be considered first-line treatment because they provide rapid relief of most allergic rhinitis symptoms without safety and tolerability issues. Additional therapeutic agents can then be added or substituted based on individual symptom response.

Abstract
Allergic rhinitis (AR) is now recognised as a global health problem that affects 10-30% of adults and up to 40% of children. Each year, millions of patients seek treatment from their healthcare provider. However, the prevalence of AR maybe significantly underestimated because of misdiagnosis, under diagnosis and failure of patients to seek medical attention. In addition to the classical symptoms such as sneezing, nasal pruritus, congestion and rhinorrhoea, it is now recognised that AR has a significant impact on quality of life (QOL). This condition can lead to sleep disturbance as a result of nasal congestion, which leads to significant impairment in daily activities such as work and school. Traditionally, AR has been subdivided into seasonal AR (SAR) or perennial AR (PAR). SAR symptoms usually appear during a specific season in which aeroallergens are present in the outdoor air such as tree and grass pollen in the spring and summer and weed pollens in the autumn (fall); and PAR symptoms are present year-round and are triggered by dust mite, animal dander, indoor molds and cockroaches. Oral histamine H(1)-receptor antagonists (H(1) antihistamines) are one of the most commonly prescribed medications for the treatment of AR. There are several oral H(1) antihistamines available and it is important to know the pharmacology, such as administration interval, onset of action, metabolism and conditions that require administration adjustments. When prescribing oral H(1) antihistamines, the healthcare provider must take into account the clinical efficacy and weigh this against the risk of adverse effects from the agent. In addition to the clinical efficacy, potential for improvement in QOL with a particular treatment should also be considered.

Abstract
BACKGROUND Allergic rhinoconjunctivitis patients are often treated with nasal or systemic allergy therapy, forgoing therapy for ocular symptoms. This treatment regimen leaves important aspects of the allergic reaction untreated and affects quality of life (QoL). The Rhinoconjunctivitis Quality of Life Questionnaire and the Allergic Conjunctivitis Quality of Life Questionnaire quantify separate aspects of QoL. OBJECTIVE To determine the benefit gained in QoL, measured by these questionnaires, when antiallergy eyedrops (olopatadine) were added to patients' preexisting regimens of nasal or systemic allergic rhinitis treatment. METHODS This was a 4-week prospective, multicenter, open-label, crossover, environmental QoL study. Visit 1 randomized patients to treatment group A or B and included baseline examinations and questionnaires. Group A instilled olopatadine twice daily and concomitantly with previously prescribed nasal or systemic antiallergy medication for 2 weeks. Group B received no ocular therapy and used only previously prescribed antiallergy medication for 2 weeks. Treatment group crossover occurred at visit 2. Patients again completed the questionnaires at visits 2 and 3. RESULTS Two hundred patients completed the study, 97 in group A and 103 in group B. Groups A and B experienced ocular allergic symptoms for 3.88 and 3.96 days, respectively, during the week before baseline. At visits 2 and 3, questionnaire scores were significantly improved for each group when olopatadine was added compared with the nontreatment periods. By visit 2, olopatadine improved QoL by 49% compared with 5% in the nontreated group (P < .001). CONCLUSIONS In this study, 90.5% of patients with allergic rhinitis treated nasally or systemically also had ocular allergic symptoms. Adding olopatadine to these patients' medication regimens significantly improved ocular allergic symptoms and overall QoL.

Abstract
BACKGROUND Diagnosing and managing the symptoms of allergic rhinitis are largely the responsibility of family physicians and allergists, but some patients choose self-management. However, few data are available to determine how the choice of care relates to measures of patient outcomes, such as the ability to perform activities, quality of life, and productivity. OBJECTIVE To examine and compare patients' ability to perform activities, quality of life, productivity, and symptoms according to care provider: family physician, allergist, or self-management. METHODS A questionnaire was developed and mailed to 2,065 patients enrolled in a 500,000-member managed care organization. Patients were identified by diagnostic codes for allergic rhinitis as determined from a retrospective examination of medical and prescription claims records between January 1, 2000, and December 31, 2000. RESULTS Chi-squared Tests revealed statistically significant differences for symptoms, family history, testing, immunotherapy, and test value among patient care providers. Multivariate analysis of variance revealed statistically significant differences for activities, symptoms, and quality of life among patient care providers. Findings support the use of diagnostic testing to improve patient outcomes. Symptoms were statistically significantly associated with measures of productivity. CONCLUSIONS Patient outcomes vary with respect to patient care group. It is imperative that patients suspected of having allergic rhinitis undergo appropriate evaluation and testing. Outcomes can be optimized if allergists and family physicians have access to appropriate diagnostic tools, such as skin testing and serologic tests for specific IgE antibodies.

Abstract
Because of its bothersome symptoms, allergic rhinitis (AR) is 1 of the top 10 reasons for patient visits to primary care physicians. This highly prevalent disease also results in loss of productivity, both at work and in school. Oral antihistamines are one of the most frequently prescribed medications for the management of AR and, with several agents available, it is important to discern the specific benefits and detriments of each. To assess the differences in efficacy and safety factors among antihistamines, the Individual therapeutic window of each agent can be used as a comparative reference tool because it defines the dose range over which an antihistamine is efficacious and free of adverse effects. As such, the therapeutic window includes both undesired effects, such as sedation, and desired properties, such as rapid onset of action, long duration of efficacy, broad age range of applicability, and potential to Improve quality of life. Therefore, agents with broad therapeutic windows, based on both efficacy and safety, are expected to be more favorable; this therapeutic window should be understood by the primary care physician when prescribing a medication.

Abstract
OBJECTIVES Newer oral allergic rhinitis (AR) medications, the second-generation antihistamines (SGAs) have gained widespread acceptance because of their efficacy and reduced side effects relative to first-generation antihistamines (FGAs). There are no empirical studies comparing the costs of treatment of SGAs relative to FGAs. METHODS We analyzed data from a 20% beneficiary sample (approximately 120,000 continuously enrolled beneficiaries per year) for the Medi-Cal Fee-for-Service program during 1999 to 2000. AR medications available under Medi-Cal included three SGA medications (loratadine, fexofenadine, and cetirizine) and over 200 FGA products containing either diphenhydramine or chlorpheniramine or both. Because multiple medications were evaluated, a sample selection model was estimated using a two-stage multinomial logistic--variance components regression framework. RESULTS SGA medications have significantly lower total direct health-care treatment costs per patient than FGA medications with costs ranging from US 347 dollars to US 448 dollars less (P < 0.001), despite higher AR medication costs. Total drug expenditures were also not significantly different for patients using SGA or FGA medications despite SGA prescriptions averaging US 47 dollars higher than FGAs. Emergency department visits, inpatient admissions and physician office visits were also significantly lower for patients using SGA medications. CONCLUSIONS Significant cost and utilization reductions were associated with all of the SGA medications relative to FGA drugs, despite their higher acquisition costs. If facing higher copayments for prescription AR drugs, many patients, particularly lower income patients, may choose cheaper over-the-counter (OTC) FGAs rather than SGAs. Our analysis finds this might lead to increased overall health-care treatment costs, unless Medicaid and health insurance plans subsidize OTC AR medications.

Abstract
BACKGROUND: Studies using homeopathy have reported beneficial effects from treating allergy-related conditions. OBJECTIVE: To investigate the effects of a homeopathic drug prepared from common allergens (tree, grass, weed species) specific to the Southwest region of the US. METHODS: A 4-week, double-blind clinical trial comparing homeopathic preparations with placebo was conducted in the Phoenix metropolitan area during the regional allergy season from February to May. Participants included 40 men and women, 26–63 years of age, diagnosed with moderate to severe seasonal allergic rhinitis symptoms. Study outcomes included allergy-specific symptoms using the rhinoconjunctivitis quality-of-life questionnaire (RQLQ), functional quality of life using the Medical Outcomes Study Short Form-36 (MOS SF-36), and the work productivity and activity impairment (WPAI) questionnaire. RESULTS: Scales from the RQLQ, MOS SF-36, and WPAI questionnaire showed significant positive changes from baseline to 4 weeks in the homeopathic group compared with the placebo group (p < 0.05). Subjects reported no adverse effects during the intervention period. CONCLUSIONS: These preliminary findings indicate potential benefits of the homeopathic intervention in reducing symptoms and improving quality of life in patients with seasonal allergic rhinitis in the Southwestern US.
