Abstract
BACKGROUND In allergic rhinitis, a relevant outcome providing information on the effectiveness of interventions is needed. In MASK-air (Mobile Airways Sentinel Network), a visual analogue scale (VAS) for work is used as a relevant outcome. This study aimed to assess the performance of the work VAS work by comparing VAS work with other VAS measurements and symptom-medication scores obtained concurrently. METHODS All consecutive MASK-air users in 23 countries from 1 June 2016 to 31 October 2018 were included (14 189 users; 205 904 days). Geolocalized users self-assessed daily symptom control using the touchscreen functionality on their smart phone to click on VAS scores (ranging from 0 to 100) for overall symptoms (global), nose, eyes, asthma and work. Two symptom-medication scores were used: the modified EAACI CSMS score and the MASK control score for rhinitis. To assess data quality, the intra-individual response variability (IRV) index was calculated. RESULTS A strong correlation was observed between VAS work and other VAS. The highest levels for correlation with VAS work and variance explained in VAS work were found with VAS global, followed by VAS nose, eye and asthma. In comparison with VAS global, the mCSMS and MASK control score showed a lower correlation with VAS work. Results are unlikely to be explained by a low quality of data arising from repeated VAS measures. CONCLUSIONS VAS work correlates with other outcomes (VAS global, nose, eye and asthma) but less well with a symptom-medication score. VAS work should be considered as a potentially useful AR outcome in intervention studies.

Abstract
SummaryIn order to determine whether an association exists between antiphospholipid antibodies (APLA) and thromboembolic events in patients with systemic lupus erythematosus (SLE), we performed a cross-sectional study of consecutive unselected SLE patients. The occurrence of previous thromboembolic events was determined by investigators blinded to the APLA status of the patients by critical review of objective tests that had been performed at the time of symptomatic presentation and by performing venous Doppler ultrasound of the legs to elicit venous reflux as an indication of previous venous thrombosis. The presence of APLA was determined by coagulation assays for the lupus anticoagulant (LA) using five tests with well-defined control ranges and by ELISA assay for anticardiolipin antibodies (ACLA). These tests were measured on two separate occasions. The results of the study demonstrate a statistically significant association between persistently abnormal ACLA assays and thromboembolic events and a non-significant trend between persistently abnormal LA and thromboembolic events. Transient abnormalities of LA and ACLA were less strongly associated with thromboembolic events. We conclude that in patients with SLE, there is a significant association between thromboembolism and APLA.

Abstract
BACKGROUND Haemopoietic progenitor cells (HPC) migrate to sites of allergic inflammation where, upon stimulation with epithelial cytokines, they produce Th2 cytokines and differentiate into mature eosinophils and basophils. They also express Toll-like receptors (TLR) involved in antimicrobial responses. OBJECTIVE The objective of this study was to compare TLR expression on peripheral blood HPC and TLR-induced responses, in particular changes in epithelial cytokine receptors, in healthy and asthmatic subjects at baseline and following allergen challenge. METHODS Ten healthy and 11 allergic asthmatic subjects were studied. HPC-enriched cell populations were stimulated with TLR-2, TLR-4 or TLR-9 ligands. TLR expression by circulating HPC and interleukin (IL)-25 (IL-17RB), IL-33 (ST2) and thymic stromal lymphopoietin receptor (TSLPR) expression after TLR ligation were examined by flow cytometry at baseline and, in asthmatics, following allergen challenge. The effects of dexamethasone (Dex) on TLR-induced responses were also assessed. RESULTS Asthmatics had significantly lower circulating HPC expressing TLR-2 and TLR-9 with a similar trend for TLR-4. TLR-4 stimulation of HPC yielded higher numbers of TSLPR+ cells in asthmatics compared with healthy subjects. A similar trend was seen for TLR-9 ligation, an effect further augmented by allergen inhalation. Allergen challenge also enhanced TLR-induced ST2 expression on HPC. Treatment with Dex in vitro increased TLR-4-induced TSLPR expression but had no effect on other epithelial cytokine receptors. CONCLUSIONS AND CLINICAL RELEVANCE These data demonstrate an interaction between allergen and TLR ligand exposure in asthmatics. Allergen inhalation augments the TLR-induced inflammatory response by HPC, possibly leading to increased "in situ haemopoiesis" through up-regulation of TSLPR. These findings show that HPC may be a part of the pro-inflammatory cascade in pathogen-induced asthma exacerbation through their increased responsiveness to TLR stimulation.

Abstract
The Allergic Rhinitis and its Impact on Asthma (ARIA) initiative commenced during a World Health Organization workshop in 1999. The initial goals were (1) to propose a new allergic rhinitis classification, (2) to promote the concept of multi-morbidity in asthma and rhinitis and (3) to develop guidelines with all stakeholders that could be used globally for all countries and populations. ARIA—disseminated and implemented in over 70 countries globally—is now focusing on the implementation of emerging technologies for individualized and predictive medicine. MASK [MACVIA (Contre les Maladies Chroniques pour un Vieillissement Actif)-ARIA Sentinel NetworK] uses mobile technology to develop care pathways for the management of rhinitis and asthma by a multi-disciplinary group and by patients themselves. An app (Android and iOS) is available in 20 countries and 15 languages. It uses a visual analogue scale to assess symptom control and work productivity as well as a clinical decision support system. It is associated with an inter-operable tablet for physicians and other health care professionals. The scaling up strategy uses the recommendations of the European Innovation Partnership on Active and Healthy Ageing. The aim of the novel ARIA approach is to provide an active and healthy life to rhinitis sufferers, whatever their age, sex or socio-economic status, in order to reduce health and social inequalities incurred by the disease.

T regulatory cell phenotypes in peripheral blood and bronchoalveolar lavage from non-asthmatic and asthmatic subjects. Clin Exp Allergy 2016; 45:1654-62.

Abstract
BACKGROUND An unresolved issue in T regulatory cells' cell biology is the lack of consensus on phenotypic markers that accurately define the natural Treg (nTreg) population. OBJECTIVES To examine nTreg frequency and functional capacity in healthy controls and their frequency in asthmatic subjects using three different phenotypic strategies. We hypothesized that phenotypically different nTreg are quantitatively and functionally different. METHODS Thirty-four healthy, non-asthmatic and 17 asthmatic subjects were studied. Three nTreg phenotypes were defined as follows: nTreg1 (CD4(+) CD25(+) Foxp3(+) ), nTreg2 (CD4(+) CD25(+) CD127(low) Foxp3(+) ), and nTreg3 (CD4(+) CD25(high) Foxp3(+) ). The flow cytometric determination of nTreg frequency in peripheral blood (PB) and bronchoalveolar lavage (BAL) was performed using fluorescently labelled antibodies. Peripheral blood nTreg functional capacity was assessed using a CFSE-based suppression assay. RESULTS There was a significantly lower frequency of PB nTreg3 compared to nTreg2 and nTreg1 (P < 0.05). Both nTreg2 and nTreg3 had a significantly greater suppressive capacity than nTreg1 at T responder (Tresp) to nTreg ratios of 16 : 1 up to 1 : 1 (P < 0.01). Asthmatics exhibited a significantly lower PB nTreg3 and nTreg1 frequency than healthy controls (P < 0.05). There were no differences between healthy controls and asthmatic subjects when comparing BAL nTreg frequency. CONCLUSIONS AND CLINICAL RELEVANCE Phenotypically different nTreg subsets are quantitatively and functionally different and are variably observed in asthma. The CD4(+) CD25(high) Foxp3(+) phenotype was the least frequent, but demonstrated the greatest suppression, and was significantly lower in PB of asthmatic subjects. Consequently, it is imperative that nTreg phenotypes be clearly defined and that the interpretation of their frequency and function be phenotype specific.

Abstract
Several unmet needs have been identified in allergic rhinitis: identification of the time of onset of the pollen season, optimal control of rhinitis and comorbidities, patient stratification, multidisciplinary team for integrated care pathways, innovation in clinical trials and, above all, patient empowerment. MASK-rhinitis (MACVIA-ARIA Sentinel NetworK for allergic rhinitis) is a simple system centred around the patient which was devised to fill many of these gaps using Information and Communications Technology (ICT) tools and a clinical decision support system (CDSS) based on the most widely used guideline in allergic rhinitis and its asthma comorbidity (ARIA 2015 revision). It is one of the implementation systems of Action Plan B3 of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA). Three tools are used for the electronic monitoring of allergic diseases: a cell phone-based daily visual analogue scale (VAS) assessment of disease control, CARAT (Control of Allergic Rhinitis and Asthma Test) and e-Allergy screening (premedical system of early diagnosis of allergy and asthma based on online tools). These tools are combined with a clinical decision support system (CDSS) and are available in many languages. An e-CRF and an e-learning tool complete MASK. MASK is flexible and other tools can be added. It appears to be an advanced, global and integrated ICT answer for many unmet needs in allergic diseases which will improve policies and standards.

Abstract
Recent candidate gene and genome-wide association studies have identified "protective" associations between the single-nucleotide polymorphism (SNP) rs1837253 in the TSLP gene and risk for allergy, asthma, and airway hyperresponsiveness. The absence of linkage disequilibrium of rs1837253 with other SNPs in the region suggests it is likely a causal polymorphism for these associations, having functional consequences. We hypothesized that rs1837253 genotype would influence TSLP secretion from mucosal surfaces. We therefore evaluated the secretion of TSLP protein from primary nasal epithelial cells (NECs) of atopic and nonatopic individuals and its association with rs1837253 genotype. We found that although atopic sensitization does not affect the secretion of TSLP from NECs, there was decreased TSLP secretion in NECs obtained from heterozygous (CT; 1.8-fold) and homozygous minor allele (TT; 2.5-fold) individuals, as compared with NECs from homozygous major allele individuals (CC; P<0.05), after double-stranded RNA (dsRNA) stimulation (50 μg ml(-1)). Our novel results show that rs1837253 polymorphism may be directly involved in the regulation of TSLP secretion. This may help explain the protective association of this genetic variant with asthma and related traits. Identifying functional consequences of SNPs in genes with previously reported clinical associations is critical in understanding and targeting allergic inflammation.

Abstract
BACKGROUND Inhaled peptide challenge has been shown to induce T cell-mediated, isolated late asthmatic reaction (LAR), characterized by recruitment of CD4(+) T cells and increased levels of thymus and activation-regulated chemokine (TARC; CCL17). Epithelial-derived thymic stromal lymphopoietin (TSLP) has been shown to modulate dendritic cell function to promote TH 2 responses via CCL17 production. OBJECTIVES To elucidate the mechanisms involved in allergen-specific T cell-induced LAR and recruitment of CD4(+) T cells by examining the effects of T cell-derived factors on the induction of TSLP in primary bronchial epithelial cells (PBEC). METHODS PBEC grown at air-liquid interface from healthy individuals and patients with asthma were stimulated with double-stranded RNA (dsRNA) or supernatants from activated allergen-specific T cells. TSLP was measured in PBEC culture supernatants. Neutralizing antibodies and signalling inhibitors were used to examine the mechanisms responsible for the induction of epithelial-derived TSLP. The functional activity of PBEC-derived TSLP was measured using a bioassay involving the induction of CCL17 production from monocyte-derived dendritic cells (moDC). RESULTS Both dsRNA and allergen-specific T cells induced enhanced TSLP secretion from asthmatic PBEC compared to healthy PBEC. Activated PBEC culture supernatant induced TSLP-dependent CCL17 production from moDC in a manner related to clinical asthmatic status. IL-1β, IL-6, and CXCL8, rather than TH 2 cytokines (IL-4/5/13), appeared to be the principle mediators of allergen-specific T cell-dependent induction of epithelial-derived TSLP, which was regulated by the MEK, MAPK, and NFκB pathways. CONCLUSION AND CLINICAL RELEVANCE Our data reveal a novel effect of allergen-specific T cells as a positive regulator of TSLP production by epithelial cells, suggesting T cell-airway epithelium interactions that may lead to maintenance and amplification of allergic inflammation. TSLP is currently a candidate for therapeutic intervention in asthma, but the factors that drive TSLP expression (T cell-derived factors) may be equally relevant in the treatment of allergic inflammation.

Abstract
BACKGROUND It is hypothesised that complex interactions between genetic and environmental factors give rise to allergy and asthma in childhood. The Canadian Healthy Infant Longitudinal Development (CHILD) study was designed to explore these factors. METHODS CHILD is a longitudinal, general population birth cohort study following infants from mid-pregnancy to age 5 years. Over this time period, biological samples, questionnaires, clinical measures and environmental data are collected. RESULTS A total of 3624 families have been recruited, and many thousands of samples and questionnaires have been collected, annotated, and archived. This report outlines the rationale and methodology for collecting and storing diverse biological samples from parents and children in this study, and the mechanisms for their release for analyses. CONCLUSIONS The CHILD sample and data repository is a tremendous current and future resource and will provide a wealth of information not only informing studies of asthma and allergy, but also potentially in many other aspects of health relevant for Canadian infants and children.

Abstract
OBJECTIVE Anti-cyclic citrullinated peptide (CCP) antibody is an established marker in the diagnosis and prognostication of rheumatoid arthritis (RA). Infrequently, systemic lupus erythematosus (SLE) patients also develop a deforming erosive arthritis, similar to that of RA. Our objective was to determine whether anti-CCP antibody is a useful marker of erosive disease in SLE patients presenting with arthritis. METHODS Electronic databases EMBASE, MEDLINE and non-indexed MEDLINE citations were searched through April 11, 2014, using the outlined key terms. Studies meeting predefined inclusion and exclusion criteria were reviewed. Two reviewers independently assessed the quality of included articles using previously described criteria. The DerSimonian-Laird random effects model was used to calculate pooled sensitivity and specificity of anti-CCP antibody for erosive arthritis in SLE. RESULTS Seven articles met inclusion and exclusion criteria. A total of 609 SLE patients with arthritis were identified, 70 of whom had erosive disease. Pooled sensitivity and specificity of anti-CCP antibody for erosive arthritis was 47.8% (95% CI, 26.2%-70.2%) and 91.8% (95% CI, 78.4%-97.2%), respectively. CONCLUSION Our findings suggest that anti-CCP antibody is a highly specific marker for erosive arthritis in SLE. Longitudinal prospective studies are needed to determine if anti-CCP antibody can be used as a predictor of erosive disease.

Abstract
Allergic rhinitis (AR) and asthma represent global health problems for all age groups. Asthma and rhinitis frequently coexist in the same subjects. Allergic Rhinitis and its Impact on Asthma (ARIA) was initiated during a World Health Organization workshop in 1999 (published in 2001). ARIA has reclassified AR as mild/moderate-severe and intermittent/persistent. This classification closely reflects patients' needs and underlines the close relationship between rhinitis and asthma. Patients, clinicians, and other health care professionals are confronted with various treatment choices for the management of AR. This contributes to considerable variation in clinical practice, and worldwide, patients, clinicians, and other health care professionals are faced with uncertainty about the relative merits and downsides of the various treatment options. In its 2010 Revision, ARIA developed clinical practice guidelines for the management of AR and asthma comorbidities based on the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) system. ARIA is disseminated and implemented in more than 50 countries of the world. Ten years after the publication of the ARIA World Health Organization workshop report, it is important to make a summary of its achievements and identify the still unmet clinical, research, and implementation needs to strengthen the 2011 European Union Priority on allergy and asthma in children.

OBJECTIVE The aim of the present study was to investigate whether environmental factors are associated with changes in numbers of circulating Eo/B progenitors at 1 year of age. METHODS Peripheral blood from 60 1-year-old children enrolled in the LINA (Lifestyle and environmental factors and their Influence on Newborns Allergy risk) birth cohort was assessed for Eo/B progenitor cells (Eo/B CFU) using standardized and validated methylcellulose assays. Frozen peripheral blood mononuclear cells (PBMC) were cultured in the presence of IL-3, IL-5 or GM-CSF, and Eo/B CFUs enumerated. Clinical outcomes and exposure to environmental tobacco smoke (ETS) were documented by standardized questionnaires, and indoor volatile organic compound (VOC) concentrations were assessed by passive sampling. RESULTS Children with skin manifestations (atopic dermatitis or cradle cap) within the first year of life had higher numbers of circulating IL-3-, IL-5- or GM-CSF-stimulated Eo/B CFUs (P < 0.05) at 1 year. In children with cradle cap, a positive correlation was found between Eo/B CFUs and exposure to ETS-related VOCs during pregnancy or at 1 year of age (P < 0.05). CONCLUSIONS AND CLINICAL RELEVANCE This is the first demonstration that environmental exposures are positively associated with levels of circulating Eo/B progenitors. The recruitment and differentiation of Eo/B progenitors in response to environmental triggers may play a role in the development of skin manifestations during the first year of life.

Abstract
The links between asthma and rhinitis are well characterized. The Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines stress the importance of these links and provide guidance for their prevention and treatment. Despite effective treatments being available, too few patients receive appropriate medical care for both diseases. Most patients with rhinitis and asthma consult primary care physicians and therefore these physicians are encouraged to understand and use ARIA guidelines. Patients should also be informed about these guidelines to raise their awareness of optimal care and increase control of the two related diseases. To apply these guidelines, clinicians and patients need to understand how and why the recommendations were made. The goal of the ARIA guidelines is to provide recommendations about the best management options for most patients in most situations. These recommendations should be based on the best available evidence. Making recommendations requires the assessment of the quality of available evidence, deciding on the balance between benefits and downsides, consideration of patients’ values and preferences, and, if applicable, resource implications. Guidelines must be updated as new management options become available or important new evidence emerges. Transparent reporting of guidelines facilitates understanding and acceptance, but implementation strategies need to be improved.

Abstract
Haemopoietic myeloid progenitors contribute to the ongoing recruitment of pro-inflammatory cells, such as eosinophils and basophils (Eo/B), to target tissue sites in allergic diseases. It is apparent that the development of allergic inflammation is critically dependent on the ability of the bone marrow to support the proliferation, differentiation and mobilization of haemopoietic progenitors. The haemopoietic inductive microenvironment in the bone marrow is crucial for providing signals necessary for maintenance of progenitor populations at varying stages of lineage commitment and permitting these cells to circulate in the bloodstream. Progenitors demonstrate responsiveness to specific cytokines, which varies with stage of differentiation. Pro-inflammatory signals, Th2 cytokines in particular, generated following allergen challenge, can impact on haemopoietic progenitor differentiation and mobilization, leading to accelerated Eo/B production. Allergen inhalation by allergic asthmatics induces a time-dependent change in cytokine levels within the bone marrow compartment, influencing differentiation of Eo/B progenitors, as evidenced by the relationship between increased bone marrow IL-5 levels and Eo/B production. It is proposed that inhaled allergen induces trafficking of IL-5-producing T lymphocytes to the bone marrow, further promoting eosinophilopoiesis through IL-5R signalling. In this manner, Th2 lymphocyte trafficking from the airway may regulate events occurring in the bone marrow. Negative regulators of Eo/B differentiation, including Th1 cytokines, may prove to be important for restoring homeostasis. Eo/B progenitors are also altered in cord blood of infants at risk of atopy and asthma, offering a potential biomarker for, and raising the possibility that Eo/B progenitors are directly involved in the development of allergic disease. For example, changes in the expression of haemopoietic cytokine receptors on cord blood progenitor cells are associated with maternal allergic sensitization, atopic risk and its development, suggesting that haemopoietic processes underlying the allergic phenotype may begin to evolve in the perinatal period.

Abstract
Allergic rhinitis is a major chronic respiratory disease because of its prevalence, impacts on quality of life and work/school performance, economic burden, and links with asthma. Family doctors (also known as 'primary care physicians' or 'general practitioners') play a major role in the management of allergic rhinitis as they make the diagnosis, start the treatment, give the relevant information, and monitor most of the patients. Disease management that follows evidence-based practice guidelines yields better patient results, but such guidelines are often complicated and may recommend the use of resources not available in the family practice setting. A joint expert panel of the World Organization of Family Doctors (Wonca), the International Primary Care Airways Group (IPAG) and the International Primary Care Respiratory Group (IPCRG), offers support to family doctors worldwide by distilling the globally accepted, evidence-based recommendations from the Allergic Rhinitis and its Impact on Asthma (ARIA) initiative into this brief reference guide. This guide provides tools intended to supplement a thorough history taking and the clinician's professional judgment in order to provide the best possible care for patients with allergic rhinitis. A diagnostic Questionnaire specifically focuses the physician's attention on key symptoms and markers of the disease. When questionnaire responses suggest a diagnosis of allergic rhinitis, a Diagnosis Guide and a simple flowchart then lead the clinician through a series of investigations commonly available in primary care to support the diagnosis. In addition, key aspects of differential diagnosis are illuminated. According to ARIA, allergic rhinitis may be classified as Intermittent or Persistent, and as Mild or Moderate/Severe. The classification of rhinitis determines the treatment necessary, as set out in an ARIA flowchart included in this guide. The guide also includes information about the strength of evidence for efficacy of certain rhinitis treatments, a brief discussion of pediatric aspects, and a glossary of allergic rhinitis medications to assist the clinician in making medication choices for each individual patient. Finally, many patients with allergic rhinitis also have concomitant asthma, and this must be checked. The World Organization of Family Doctors has been delegated by WHO as the group that will be taking primary responsibility for education about chronic respiratory diseases among primary care physicians globally. This document will be a major resource in this educational program.

Abstract
OBJECTIVE To evaluate the effect of a single nasal allergen challenge on peripheral blood eosinophil/basophil (Eo/B) progenitor cells and induced sputum eosinophil counts in subjects with allergic rhinitis. METHODS Sixteen adults entered a sequential nasal control and allergen challenge study, outside the pollen season. Blind assessment of peripheral blood Eo/B progenitor colony forming units (CFU), induced sputum and nasal lavage cell counts was made before and 24 h after both challenges. Subjects recorded their rhinitis symptoms and nasal peak inspiratory flow, hourly at home, following both challenges. RESULTS When comparing the values 24 h after the control vs. the allergen challenge, there were no significant differences in Eo/B progenitor CFU (control (mean, SD): 3.6 (1.0)/10(6) cells; allergen: 4.4 (1.1)/10(6) cells) or sputum eosinophils (control (median, inter-quartile range): 1.0 (0.3-1.7)%; allergen: 0.7 (0.0-1.3)%) despite a significant increase in the percentage (median (inter-quartile range) of eosinophils in nasal lavage (control: 0.6 (0.1-0.9)%; allergen; 1.9 (0.9-8.1)% and significant worsening of nasal peak inspiratory flow and rhinitis symptoms. CONCLUSIONS Despite a significant increase in nasal symptoms and lavage eosinophil counts, a single nasal allergen challenge was not sufficient to elicit a measurable haemopoietic response in circulation, or an increase in sputum eosinophil counts.

Abstract
Nervous system involvement in systemic lupus erythematosus (SLE) is typically diagnosed on the basis of clinical psychiatric and/or neurologic syndromes (NPSLE). Neuropsychological tests can be used to assess nervous system integrity even in the absence of major NP syndromes. Their application has uncovered significant cognitive dysfunction, ranging from mild to severe, in a sizeable proportion of SLE patients irrespective of clinical NP status. Cognitive dysfunction has now been accepted as a bona fide manifestation of NPSLE. The heterogeneity of clinical NPSLE manifestations is paralleled by the diversity of cognitive deficits reported in different studies and within different patients. The success of attempts to explain these deficits on the basis of potential pathogenetic mechanisms, such as antibrain antibodies and proinflammatory cytokines, has been uneven. To date, the most robust findings have emerged in relation to antiphospholipid antibodies, which carry with them important therapeutic implications.

Abstract
Eosinophilic infiltration is a cardinal feature of allergic inflammation; based upon its biological actions, the eosinophil has assumed the role as the principal inflammatory cell in asthma. In assessing the mechanisms by which eosinophils are recruited to sites of inflammation, a sizeable body of evidence exists supporting the proposal that expansion of hemopoietic compartments in the bone marrow stimulates an increased turnover and traffic of mature eosinophils to the site of allergic inflammation. In addition, recent findings point to the possible egress and traffic of primitive progenitor cells to the site of inflammation where in-situ differentiation may provide a continued supply of pro-inflammatory cells. In the present article, we will review the evidence for these findings, and discuss the rationale for targeting hemopoiesis and migrational pathways of hemopoietic cells in the treatment of allergic disease. In this context, we will discuss the effect of corticosteroid treatment on hemopoietic mechanisms; the effects of therapies that inhibit the actions of cysteinyl leukotrienes (CysLTs); the effects of in vivo blockade of the eosinophil-active cytokine, interleukin (IL)-5; and, the effects of antihistamines on hemopoiesis. In addition, we will address the potential role that small molecular weight chemokine receptor antagonists may play in modulating progenitor cell trafficking to tissue sites of inflammation.

Abstract
Increasing levels of proinflammatory cells, including eosinophils and basophils, are seen at the site of allergen challenge in allergic disease of the airways. Mechanisms for the recruitment of these cell types could involve either specific upregulation of adhesion molecule and chemoattraction, or the initiation of proliferation and differentiation of inflammatory cell progenitors derived from the bone marrow. In this study, we demonstrate, in two systems of eosinophilic-basophilic lineage-committed granulocytes of relative immaturity, that eosinophilic differentiation in vivo implies the induction of a distinct adhesion phenotype, characterized by the upregulation of beta(7) integrin and downregulation of beta(1) and alpha(5) integrins. Moreover, the eosinophilic differentiation induced an upregulation of complement receptor type 1 and type 3, and the expression was further enhanced upon a short-course in vitro activation with ionomycin. These data indicate a sequential alteration of disparate members of the integrin family during eosinophilic-basophilic differentiation, which may attribute to specific adhesion requirements at distinct stages of cell maturation.

Abstract
BACKGROUND Dendritic cells (DC) are thought to play a key role in the initiation and maintenance of T cell immunity to inhaled antigens. While the density of DC within the bronchial mucosa is increased in stable asthma, there is little information currently available concerning the effects of allergen inhalation on DC in subjects with asthma. OBJECTIVES To enumerate changes in the numbers of circulating CD33(+) myeloid DC in asthmatics, before and after allergen challenge. METHODS Blood DC numbers were enumerated by flow cytometry before and at 3, 6 and 24 h after inhaled allergen and diluent in 10 mild, allergic asthmatic subjects. RESULTS Blood DC numbers rapidly fell from 3.42 +/- 0.30 x 10(7)/L at baseline, to 2.10 +/- 0.17 x 10(7)/L by 3 h post-challenge (P < 0.01), and remained significantly below baseline values at both 6 and 24 h following allergen challenge. No such changes in DC numbers were noted after diluent challenge. A similar, early fall in circulating lymphocytes was also noted post-allergen challenge, whereas changes in circulating eosinophil and neutrophil numbers occurred more slowly. CONCLUSIONS A significant proportion of myeloid DC rapidly 'disappear' from the circulation following allergen inhalation, suggesting that margination of circulating myeloid DC, and their recruitment into the airway mucosa, is an important feature of the immune response to inhaled allergen.

Abstract
OBJECTIVES To describe an older patient with delirium attributed to systemic lupus erythematosus (SLE) and to review the literature on neuropsychiatric manifestations of SLE in older people. DESIGN Case report and literature review. MEDLINE search using terms systemic lupus erythematosus, neurologic, psychiatric, neuropsychiatric, autoantibodies (anti-nuclear antibody (ANA), antiphospholipid, anticardiolipin, anti-double stranded deoxyribonucleic acid (anti-dsDNA), anti-Smith), and elderly. Additional articles obtained from hand-searched references and through experts. SETTING Hospital (case report). PARTICIPANTS Case report and literature cases. MEASUREMENTS None. RESULTS SLE is increasingly diagnosed in older adults. Onset is insidious and diagnosis is delayed because of a different clinical spectrum and immunological profile than in younger adults. Autoantibodies have an important role in the pathogenesis of neuropsychiatric manifestations, while vasculitis is less common. Aggressive immunosuppressive therapy is typically indicated, although recent case reports suggest that lower doses may suffice. The American College of Rheumatology 1982 revised criteria may be inadequate to diagnose neuropsychiatric lupus in older persons. CONCLUSION Neuropsychiatric symptoms can be prominent in older people, presenting features of SLE. This case illustrates the lowest dose of corticosteroids shown to be effective in an older patient with delirium due to SLE.

Abstract
In recent years, there has been an increasing appreciation of the important contribution of bone-marrow-related, hemopoietic mechanisms to allergic diseases. Eosinophil/basophil-progenitor levels fluctuate in the peripheral blood during allergen exposure and the cells home to peripheral tissue, where they differentiate. It is becoming apparent that several cytokines, particularly IL-5, have multiple effects on progenitors and allergic inflammation. Within the past few years, studies of the therapeutic implications of this bone marrow contribution to atopy have been initiated; the effects of corticosteroids, leukotriene-receptor blockers, antagonism of IL-5 and modulation of differentiation by retinoic acid on progenitors will be reviewed.

Abstract
The chronic, lupus-like autoimmune disease in MRL-lpr mice is associated with leucocyte infiltration into the choroid plexus, brain cell death, and deficits in motivated behavior. The presence of lymphoid cells in the ventricular lumen and the increased number of TUNEL-positive cells in periventricular areas led to the hypothesis that immune cells enter into the cerebrospinal fluid (CSF) and induce primary neuronal damage in regions bordering the cerebral ventricles. Using an in vitro approach, we presently examine the possibility that CSF from autoimmune mice is neurotoxic and/or gliotoxic. The CSF and serum from diseased MRL-lpr mice, less symptomatic MRL +/+ controls, and healthy Swiss/Webster mice (non-autoimmune controls) were frozen until their effects on the viability of pyramidal neurons and astrocytes were assessed in a two-color fluorescence assay. Significant reduction in neuronal viability (in some cases as low as 67%) was observed in the co-cultures of hippocampal neurons and astrocytes incubated for 24 h with CSF from autoimmune MRL-lpr mice. The viability of astrocytes did not differ among the groups, and the CSF from autoimmune mice appeared more toxic than the serum. The behavior of MRL-lpr mice differed significantly from the control groups, as indicated by impaired exploration, reduced intake of palatable food, and excessive immobility in the forced swim test. The present results suggest that CSF from the behaviorally impaired lupus-prone mice is neurotoxic and are consistent with the hypothesis that neuroactive metabolites are produced intrathecally in neuropsychiatric lupus erythematosus.

Abstract
The role of inflammatory effector cells in the pathogenesis of airway allergy has been the subject of much investigation. However, whether systemic factors are involved in the development of local responses in both upper and lower airways has not been fully clarified. The present study was performed to investigate aspects of the pathogenesis of isolated allergic rhinitis in a murine model sensitized to ovalbumin (OVA). Both upper- and lower-airway physiological responsiveness and inflammatory changes were assessed, as well as bone marrow progenitor responses, by culture and immunohistological methods. Significant nasal symptoms and hyper-responsiveness appeared after intranasal OVA challenge (P < 0.0001 and P < 0.01, respectively), accompanied with significant nasal mucosal changes in CD4+ cells (P < 0.001), interleukin (IL)-4+ cells (P < 0.01), IL-5+ cells (P < 0.01), basophilic cells (P < 0.02) and eosinophils (P < 0.001), in the complete absence of hyper-responsiveness or inflammatory changes in the lower airway. In the bone marrow, there were significant increases in CD34+ cells, as well as in eosinophils and basophilic cells. In the presence in vitro of mouse recombinant IL-5, IL-3 or granulocyte-macrophage colony-stimulating factor (GM-CSF), the level of bone marrow eosinophil/basophil (Eo/Baso) colony-forming cells increased significantly in the OVA-sensitized group. We conclude that, in this murine model of allergic rhinitis, haemopoietic progenitors are upregulated, which is consistent with the involvement of bone marrow in the pathogenesis of nasal mucosal inflammation. Both local and systemic events, initiated in response to allergen provocation, may be required for the pathogenesis of allergic rhinitis. Understanding these events and their regulation could provide new therapeutic targets for rhinitis and asthma.

Abstract
The onset of autoimmunity in lupus-prone mice is accompanied by a constellation of behavioral deficits, termed Autoimmunity-Associated Behavioral Syndrome (AABS). In particular, a spontaneous increase in serum interleukin-6 (IL-6) levels in five-week old MRL-lpr mice coincides temporally with blunted responsiveness to sucrose and excessive immobility in the forced swim test. These relationships, along with evidence that sucrose intake drops after systemic IL-6 overexpression is induced in healthy mice, have led to the hypothesis that sustained elevation in serum IL-6 also induces other aspects of AABS. This hypothesis is tested by comparing the behavioral profiles of healthy mice infected with Ad5mIL6 adenovirus (2 x 10(8) pfu of virus/mouse i.p.) with those of animals infected with control Ad5 virus. This methodology was used to achieve high circulating levels of IL-6, to overcome the problem of its short half-life, and to avoid the stressful effects of repeated injections. The Ad5mIL6 infection (known to induce excessive IL-6 levels over five days) transiently reduced food, water, and sucrose intake, as well as rectal temperature in MRL +/+ and AKR/J mice. Although the level of locomotor activity did not decline, Ad5mIL6-infected AKR/J mice demonstrated less novel object exploration. Performance in the step-down, plus-maze, and spontaneous alternation tests were disturbed to various degrees in all infected animals. The present results suggest that prolonged exposure to circulating IL-6 primarily impairs ingestive behavior, likely reflecting enhanced catabolism. The inability of circulating IL-6 to alter other aspects of behavior supports the hypothesis that multiple immuno-neuroendocrine mechanisms contribute to the pathogenesis of AABS.

Abstract
We and others have shown that IL-5 plays a central role in eosinophil and basophil differentiation, exerting its effects through the IL-5 receptor (IL-5R). Little is currently known concerning regulation of IL-5Ralpha gene transcription in the context of commitment of hemopoietic progenitor cells to the eosinophil and basophil lineages; recent studies have indicated that IL-5 itself can regulate IL-5Ralpha expression on mature eosinophils. We now provide evidence to indicate that IL-5 can upregulate IL-5Ralpha on bone marrow CD34+ progenitors in vitro, as we have demonstrated in vivo in atopic asthmatics. Given that all-trans retinoic acid (ATRA) is known to modulate some granulopoiesis, causing neutrophilic differentiation, we examined the effects of ATRA on eosinophil/basophil differentiation and IL-5Ralpha expression. In cultures of normal human bone marrow, ATRA selectively suppressed eosinophil/basophil differentiation. Similarly, ATRA inhibited eosinophil/basophil differentiation of cord blood CD34+ cells, while neutrophil differentiation proceeded without impediment. Most importantly, these effects of ATRA on CD34+ cells were associated with selective, dose-dependent inhibition of membrane-bound IL-5Ralpha, upregulation of soluble IL-5Ralpha transcription, but no change in GM-CSF receptor expression. These findings indicate that retinoids can differentially regulate membrane and soluble isoforms of IL-5Ralpha, and that these effects have functional consequences in vitro on eosinophil and basophil differentiation. ATRA may be of therapeutic benefit in allergic inflammatory disorders in which eosinophil differentiation and membrane-bound IL-5R are upregulated.

Abstract
Allergen inhalation by dual responder subjects with atopic asthma is associated with an increase in circulating eosinophil/basophil colony-forming units (Eo/B CFU) and granulocyte-macrophage colony- stimulating factor (GM-CSF) immunolocalization in Eo/B colony cells grown in vitro. The current study examined the effect of the inhaled corticosteroid, budesonide, on the number of allergen- induced circulating eosinophils and Eo/B CFU, and immunolocalization of GM-CSF and interleukin-5 (IL-5) in Eo/B colony cells grown in vitro. Sixteen subjects with mild atopic asthma were treated for either 7 or 8 d with 200 microg inhaled budesonide or placebo twice a day. Peripheral blood was collected before and 24 h after allergen inhalation challenge and nonadherent mononuclear cells (NAMC) were grown in methylcellulose culture. Eo/B CFU were enumerated after 14 d in culture, and prepared on slides for immunocytochemistry. Budesonide attenuated the allergen-induced increase in circulating eosinophils (4.0 +/- 0.4 x 10(5)/ml versus 6.5 +/- 0.7 x 10(5)/ml, p = 0.0001), circulating Eo/B CFU (12.4 +/- 2.3/10(6) NAMC versus 18.8 +/- 4.6/10(6) NAMC, p = 0.05), and immunolocalization of GM-CSF in Eo/B colony cells (11.8 +/- 1.9% positive versus 18.0 +/- 2.2%, p = 0.01) but not immunolocalization of IL-5 (7.9 +/- 1.4% versus 4.5 +/- 0.6%, p > 0.05). Inhaled budesonide attenuated the number of allergen-induced circulating eosinophils and their progenitors grown in the presence of GM-CSF, which may partially be a result of regulating eosinophil progenitor expression of the autocrine growth factor GM-CSF.

Abstract
Eosinophils elaborate a number of proinflammatory mediators, including immunoregulatory cytokines and chemokines. Interleukin (IL)-4 and RANTES are important cytokines that have previously been shown to be expressed by mature eosinophils. We hypothesized that de novo synthesis of IL-4 and RANTES occurs in nascent eosinophils, leading to storage of newly produced proteins in crystalloid granule-like structures. Cytokine mRNA and protein expression were examined in cultured eosinophil colonies, which were derived from purified cord blood CD34+ cells and generated in semisolid media (methylcellulose) in the presence of recombinant human (rh)IL-3 and rhIL-5. Cytokine mRNA profiles were analysed by the reverse transcription-polymerase chain reaction (RT-PCR) to determine transcription of IL-4 and RANTES in cells on days 0, 7, 14, 21 and 28 of culture. The expression of translated cytokine products and granule major basic protein (MBP) was confirmed, from day 23 onwards, for colonies cultured in semisolid media, by immunofluorescent labelling and confocal laser-scanning microscopy (CLSM). We found that mRNA sequences encoding IL-4 and RANTES were expressed in freshly prepared, non-differentiated CD34+ cells. Furthermore, RANTES mRNA localized to carbol chromotrope 2R-positive colony cells, as assessed using in situ RT-PCR on day 21 of culture in semisolid media, and was found to gradually decrease (relative to beta2-microglobulin) in rhIL-3- and rhIL-5-treated colony cells (comprising > 90% eosinophil-like cells) up to day 28. Immunoreactivity for IL-4 and RANTES co-localized with MBP in maturing colony eosinophils on day 23 of culture in semisolid media, as judged by CLSM. These results suggest that synthesis and storage of immunoregulatory cytokines, essential for processes associated with adaptive immunity, occurs in nascent eosinophils during their growth and differentiation.

Abstract
An early onset of systemic, lupus-like disease in MRL-lpr mice is accompanied by deterioration in their behavioral performance and atrophy of pyramidal neurons in the parietal cortex and the hippocampal CA1 area. Using the immunosuppressive drug cyclophosphamide (CY) to attenuate the disease, we have tested the hypothesis that the autoimmune/inflammatory process is responsible for changes in brain morphology. A modified Golgi impregnation method revealed that, in comparison to saline-treated controls, immunosuppressive treatment with CY (100 mg/kg/week i.p. over 8 weeks) increased dendritic branching and spine numerical density in the CA1 region of MRL-lpr mice and MRL +/+ mice, which develop less severe manifestations of the disease. More interestingly, CY selectively prevented the atrophy and aberrant morphology of pyramidal neurons in the parietal cortex of MRL-lpr mice. The neuropathological measures (in particular reduced dendritic spine density) significantly correlated with increased serum levels of antinuclear antibodies and splenomegaly. The present results support the hypothesis that chronic autoimmune disease induces functionally important changes in neuronal morphology, and provide an empirical basis for understanding the behavioral dysfunction in systemic lupus erythematosus and autoimmune phenomena reported in some forms of mental illness.

Abstract
In patients with allergic diseases, allergen provocation can activate a systemic response that provokes inflammatory cell production by the bone marrow. After release and differentiation of progenitor cells, eosinophils, basophils, and mast cells are typically recruited to tissues in atopic individuals. An understanding at the molecular level of the signaling process that leads to these systemic responses between the target organ, especially the airways, and the bone marrow may open up new avenues of therapy for allergic inflammatory disease. Studies that support the critical involvement of the bone marrow in the development of eosinophilic inflammation of the airways point out the systemic nature of these conditions and their potential for biologic intervention. Hemopoietic events that originate in the bone marrow are potential targets of long-term therapy for rhinitis and asthma. For example, the "beneficial" systemic activity of cortico-steroids through modulation of hemopoietic mechanisms and inflammatory cell recruitment to the airways is essential for the optimal treatment of both upper and lower airway inflammation.

Abstract
BACKGROUND The sequence of adhesion-molecule expression during eosinophil differentiation remains unclear. METHODS We analyzed the surface expression of alpha4, beta1, and beta7 integrins and compared it to established myeloid developmental markers, using the eosinophilic cell line HL-60 clone 15, as well as cord and peripheral blood differentiation assays. RESULTS Cells induced to eosinophil differentiation by treatment with butyric acid, IL-5, and GM-CSF showed a significant upregulation of beta7 integrin expression coincident with a marked upregulation of CD35 and attenuation of CD33 and beta1 integrin expression. In addition, adhesion of induced HL-60 clone 15 cells to fibronectin was attenuated by a beta7 integrin antibody. CONCLUSIONS Our data show that protein synthesis-dependent upregulation of the functional beta7 integrin occurs under conditions when beta4 and beta1 integrins are fully expressed, indicating a sequential appearance of specific adhesion molecules on differentiating eosinophil progenitors.

Abstract
BACKGROUND In allergic inflammation and asthma, eosinophils are major effector cells. They have been shown to synthesize at least 23 cytokines, some of which are stored intracellularly in their unique crystalloid granules together with cationic granule protein. Little is known about the synthesis and storage of cytokines relative to cationic granule proteins in maturing eosinophils during eosinophilopoiesis. OBJECTIVE Our purpose was to analyze the expression of eosinophil-derived mediators, major basic protein (MBP), eosinophil cationic protein (ECP), IL-6, and RANTES, during early stages of eosinophil maturation in CD34(+) cell-derived colonies. METHODS Purified human cord blood CD34(+) cells were grown in methylcellulose cultures in the presence of recombinant human IL-3 and IL-5. By confocal laser scanning microscopy, the coexpression of eosinophil granular proteins MBP and ECP was determined concurrently with IL-6 and RANTES during eosinophil maturation on days 16, 19, 23, and 28 of culture. RESULTS Immunoreactivity against MBP, ECP, IL-6, and RANTES was not detectable in freshly purified CD34(+) cells. Maturing eosinophils (>95%) exhibited positive immunostaining for all these proteins between days 16 and 28 of culture. At early stages of culture, discrete immunostaining was observed around the periphery but not in the center of granular structures. By day 28 cultured eosinophil-like cells showed evidence of the acquisition of crystalloid granule-like structures, analogous to those observed in mature peripheral blood eosinophils. CONCLUSIONS Eosinophils express and store cytokines simultaneously with cationic granule proteins during the process of maturation. We propose that the storage of cytokines during the development of eosinophils is an early event and it may be integral to inflammatory responses involving these cells. The results of this study suggest a potential immunoregulatory function for maturing eosinophils.

Abstract
BACKGROUND Recognition of the importance of dendritic cells (DC) in the initiation of T-cell-dependent immune responses has led to increasing interest in methods for the identification of DC within the circulation. We sought to develop a flow cytometric method that would allow the reliable enumeration of absolute myeloid DC counts in minimally manipulated blood samples. METHODS Myeloid DC were identified by three-color staining of whole blood leukocytes as a discrete population of mononuclear cells expressing high levels of HLA-DR and CD33, yet having little or no expression of CD14 and CD16. This method was analyzed for reproducibility and variation in blood DC number during typical clinical day hours and after exercise. The new method was compared to an established commercial kit method. RESULTS FACS sorting of the CD33(+) DC showed that they morphologically resembled immature DC, and developed cytoplasmic projections typical of mature DC following overnight culture in granulocyte macrophage-colony stimulating factor (GM-CSF). Within peripheral blood, these DC were found at a mean concentration of 17. 4 +/- 5.4 x 10(6) per liter, corresponding to 0.93 +/- 0.27% of mononuclear cells. Comparison of duplicate samples stained and analyzed in parallel showed that the intrasample variability was very low, with an intraclass correlation coefficient of 0.95. The frequency of CD33(+) myeloid DC and their light scatter characteristics were similar to that of CD11c(+) myeloid cells. Four-color FACS analysis revealed complete identity of CD11c(hi), HLA-DR(+) DC with CD33(+), HLA-DR(+) DC. Only rare CD33(+) DC coexpressed CD123 and HLA-DR. Numbers of blood myeloid DC, identified by CD33 staining, showed no significant variation during standard laboratory hours. However, their numbers rose significantly during vigorous exercise, in parallel to other blood cells. CONCLUSIONS The method described herein is rapid, reproducible, requires only small volumes of blood, can be readily used by a clinical immunology laboratory, and requires fewer antibodies than a currently available commercial method.

Abstract
Profound changes in brain morphology and behavior coincide with the spontaneous development of systemic autoimmune/inflammatory disease in Fas-deficient MRL-lpr mice. The dendrites atrophy, the density of hippocampal and cortical neurons decreases, and an anxious/depressive-like behavior emerges while lymphoid cells infiltrate into the choroid plexus of MRL-lpr mice. We hypothesized that the inherited lack of the Fas-dependent anti-inflammatory mechanism would lead to unsuppressed immune activity, characterized by reduced apoptosis in the MRL-lpr brain. Using the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeled (TUNEL) method as an indicator of apoptosis, a surprisingly high incidence of TUNEL-positive cells was observed in the hippocampus, choroid plexus and periventricular regions of MRL-lpr mice, 5-10-fold higher than that found in the MRL +/+ control brain. Immunostaining with anti-CD3, CD4 and CD8 monoclonal antibodies showed limited overlap between CD-positive and TUNEL-positive cells, suggesting that the dying cells are for the most part (approximately 70%) not T-lymphocytes. Although further characterization of the phenotype of the dying cells and the mechanism of cell death are required, the present results suggest the involvement of a Fas-independent apoptotic process in neurodegeneration induced by systemic autoimmune disease.

Abstract
Increases in bone-marrow (BM) inflammatory cell progenitors are associated with allergen-induced airway hyperresponsiveness and inflammation in asthmatics and dogs. Here, for the first time, we compare the time course of airway hyperresponsiveness, inflammation, and marrow progenitor responses in a mouse model of airway allergen challenge. Sensitized BALB/c mice were studied at 2, 12, 24, 48, and 72 h after intranasal ovalbumin or saline challenges. Outcome measurements included airway responsiveness, airway inflammation as assessed via bronchoalveolar lavage (BAL) and lung tissue sections, and BM eosinophil colony-forming units (Eo-CFU) as enumerated using a semisolid culture assay with optimal concentrations of interleukin-5. We observed significant increases in BAL fluid eosinophils, neutrophils, lymphocytes, and macrophages by 2 h after the second of two intranasal allergen challenges (P < 0.05). Significant increases in airway responsiveness or BM Eo-CFU were observed at 24 h and persisted until 48 h after the second challenge (P < 0.05). Airway inflammation, including eosinophils, persisted until at least 72 h (P < 0.05). We observed that allergen-induced airway eosinophilia is accompanied by increases in BM eosinophil progenitors, indicating that in this model, increased eosinophil production involves an expansion of the relevant stem-cell population. These findings support the use of this model to explore the mechanisms of increased eosinopoiesis observed in human asthma.

Abstract
BACKGROUND Recent findings point to an association between allergic asthma in adults and increased responsiveness of myeloid progenitor cells to certain hemopoietic growth factors. However, it is not clear at what age these changes in progenitor cells first become manifest, although increasing evidence suggests that the allergic phenotype may begin to emerge in very early life. OBJECTIVE We sought to compare expression of hemopoietic cytokine receptors on CD34(+) progenitor cells in cord blood from normal infants ("low risk" for subsequent atopy) and infants with at least one atopic first degree relative ("at risk" for subsequent atopy). METHODS Cord blood was obtained from 21 neonates. Nonadherent mononuclear cells were stained with mAbs directed against CD45, CD34, and the alpha-chains of the GM-CSF, IL-3, and IL-5 receptors and analyzed by flow cytometry. RESULTS No differences in absolute CD34(+) numbers were observed between the 2 groups. However, expression of GM-CSF receptor on CD34(+) cells was reduced in the "at-risk" compared with the "low- risk" group (P =.021), although no significant differences were noted between the 2 groups with respect to IL-3 and IL-5 receptor expression. CONCLUSION The functional sequelae of reduced GM-CSF receptor expression on CD34(+) cells remain to be determined. Nonetheless, these findings show an association between genetic risk for atopy and changes in the expression of hemopoietic cytokine receptors on cord blood progenitor cells and support the notion that the allergic phenotype may begin to evolve in the perinatal period.

Abstract
We have previously shown that allergen inhalation by asthmatics is associated with increases in bone marrow eosinophil/basophil colony-forming cells (Eo/B-CFU), and increases in CD34(+) hemopoietic progenitors expressing the alpha-subunit of the IL-5 receptor (IL-5Ralpha). This study investigated the effect of inhaled corticosteroid on baseline numbers and allergen-induced increases in these parameters. Nine subjects with mild, stable asthma inhaled budesonide (400 microgram/d) for 8 d in a placebo-controlled, double-blind, randomized crossover study. On Day 7, subjects inhaled allergen, with bone marrow sampling before and 24 h after challenge. Budesonide inhalation significantly attenuated the allergen-induced early and late asthmatic responses, degree of increase in sputum and blood eosinophils, as well as the baseline numbers of total bone marrow CD34(+) cells (p < 0.05), CD34(+)IL-3Ralpha+ cells (p < 0.01) and IL-5-responsive Eo/B-CFU (p < 0.05). Allergen inhalation significantly increased Eo/B-CFU grown in the presence of IL-3, GM-CSF, or IL-5 alone (p < 0.05) and in combination (p < 0.01), as well as the number of CD34(+)IL-5Ralpha+ cells (p < 0.01). However, these increases in Eo/B-CFU and CD34(+)IL-5Ralpha+ cells were not affected by budesonide treatment. These data demonstrate that short-term inhaled budesonide treatment has a systemic effect in inhibiting the turnover of a subpopulation of bone-marrow-derived progenitors, but that inhalation of allergen overcomes this inhibitory effect.

Abstract
The spontaneous development of autoimmune disease in MRL-lpr mice induces behavioral and endocrine changes that resemble effects of chronic stressors. To further examine the correspondence between autoimmune disease and chronic stress, we asked whether the brains of autoimmune mice show a shift in the corticotropin-releasing factor (CRF) to vasopressin (AVP) ratio. Using in situ hybridization histochemistry with 35S-labelled mouse riboprobes, the levels of mRNA transcripts encoding CRF and AVP were compared between autoimmune MRL-lpr and control MRL +/+ brains. CRF transcript levels were lower in the hypothalamic paraventricular nucleus and in the central nucleus of the amygdala in MRL-lpr mice. AVP transcript levels were higher in the paraventricular and the supraoptic nuclei in MRL-lpr mice compared to controls. CRF mRNA levels were inversely related to performance in stress-sensitive tasks and to measures of autoimmunity. As found previously for behavioral performance, immunosuppressive treatment with cyclophosphamide abolished the group difference in neuropeptide gene expression. These results indicate that an autoimmune disease process is necessary for the shift in the brain CRF:AVP ratio. Furthermore, they support the parallel between chronic stress and chronic autoimmunity/inflammation, and suggest common central mechanisms relevant to endocrine function and behavior.

Abstract
Airway inflammation in patients with nasal polyps is characterized by the increased presence of eosinophils, the numbers of which are reduced after treatment with topical corticosteroids. Because eosinophilic responses in the airways are in part due to eosinophil progenitor differentiation, we hypothesized that CD34, a cell surface, sialomucinlike glycoprotein that specifically marks hemopoietic progenitors and endothelium, would be expressed in nasal polyp tissue. We sought to identify CD34(+) leukocytes or endothelial cells in nasal polyps. We also investigated the effect of the topical corticosteroid budesonide on the numbers of CD34(+) cells and vessels in nasal polyps. To accomplish this, we performed immunostaining for CD34 protein in tissue sections of nasal polyps from topical steroid-treated and -untreated groups of patients, as well as from one patient before and after systemic corticosteroid therapy. We also examined myeloid colony formation by isolated polyp mononuclear cells, and performed flow cytometry to detect the presence of CD34(+)/CD45(+) cells within these isolated populations. We also examined the in vitro effects of steroids on human umbilical vein endothelial cell (HUVEC) expression of CD34. We detected CD34-immunoreactive mononuclear cells and blood vessels in the lamina propria of all nasal polyps. CD34(+) mononuclear cells resembled immature hemopoietic cells morphologically. Mononuclear cell fractions from polyps contained myeloid colony-forming cells and cells bearing CD45, a pan-leukocyte marker, as well as CD34, and gated as true hemopoietic blast cells. The numbers of CD34(+) cells and CD34(+) vessels in steroid-treated nasal polyps were significantly higher than in steroid-untreated nasal polyps (15.67 +/- 2.08 cells/10 hpf, versus 5.33 +/- 1.36 cells/10 hpf, P = 0.002; 101.25 +/- 6.24 vessels/0.5 mm2 of lamina propria, versus 57.22 +/- 8.00 vessels/0.5 mm2 of lamina propria, P = 0.0008, respectively). A similar upregulation of CD34 immunostaining, especially for mononuclear cells, was observed in one patient after systemic corticosteroid therapy. Steroid treatment in vitro of HUVECs did not result in enhanced CD34 expression. Both CD34(+)/CD45(+) mononuclear cells and CD34(+) endothelial cells are present within nasal polyps, with higher numbers in patients who have received topical corticosteroid treatment. Because enhancement of CD34 expression was not seen in cultured umbilical vein endothelial cells treated in vitro with corticosteroid, the findings of the study suggest that in nasal polyp tissue, steroids enhance numbers of CD34(+) progenitors and endothelial cells via indirect mechanisms.

Abstract
Accumulation of eosinophils in the airways is characteristic of allergic rhinitis and asthma. The tissue eosinophilia may involve both recruitment of mature eosinophils and proliferation of their progenitors. This study examines mature eosinophils (nasal and circulating), their circulating progenitors, and a potential role of granulocyte-macrophage colony-stimulating factor (GM-CSF) in stimulating these progenitors. Twelve subjects with a history of seasonal allergic rhinitis and positive skin prick test for birch pollen were studied during four periods: shortly before, in the early and intense phase, at the end, and well after the Swedish birch-pollen season. Nasal mucosal and circulating eosinophils were examined in both nasal brushings and peripheral blood samples. Eosinophil/basophil progenitors were determined by counting colony-forming units in nonadherent mononuclear blood-cell cultures in methylcellulose at 14 days. The nasal mucosal cytokines GM-CSF, interleukin (IL)-1beta, IL-3, IL-5, IL-6, IL-8, and RANTES were analyzed (ELISA) in nasal lavage (NAL) fluids. All patients developed severe symptoms of rhinitis at the height of the season, with increased numbers of eosinophils in the nasal mucosa (P<0.05) and in the circulation (P<0.05). At this time point, the number of circulating progenitors (P<0.05) and the NAL fluid level of GM-CSF (P<0.05) were also increased. In contrast, there was no change in the NAL fluid levels of IL-1beta, IL-3, IL-6, or IL-8. Neither IL-5 nor RANTES could be detected in any of the NAL fluids. At the end of or after the season, there was no increase in nasal eosinophils or circulating eosinophils or progenitors (P>0.05). Ex vivo addition of GM-CSF (10-100 U) increased the number of blood progenitors grown before (P<0.01) and after (P<0.05) the season, compared with during the season. The in vitro GM-CSF responsiveness of progenitors may be related to whether or not these already have been stimulated endogenously by GM-CSF. Taken together, our data thus suggest that GM-CSF may play a role in vivo to increase production of eosinophilic progenitors in allergic airway disease.
