Abstract
Chemokines are cytokines with chemotactic properties on leukocyte subsets whose modulation plays a key role in allergic inflammatory processes. To better understand the possible anti-inflammatory effects of histamine-1 receptor antagonists in allergic asthma, we studied the mRNA expression of a set of chemokines known to be involved in the eosinophils-basophils activation as well as recruitment and T-cell signaling events, before and after corticosteroid or antihistamine treatment in PBMCs from allergic-asthmatic patients ex vivo. Twelve patients were enrolled, all of whom were allergic to Parietaria judaica and suffering for mild persistent asthma: six were treated with desloratadine (10 mg/day), and six with deflazacort (12 mg/day). Before and after the treatment, PBMC samples were collected from each patient and analyzed for the expression of encoding mRNAs for several chemokines, I-309 (CCL1), MCP-1 (CCL2), MIP1-alpha (CCL3), MIP1-beta (CCL4), RANTES (CCL5), IL-8 (CXCL8), IP-10 (CXCL10), Lymphotactin (XCL1). Clinical and functional improvements were seen after 3 weeks of therapy; this was associated with a reduced expression in the mRNA levels for the chemokines RANTES, MIP1-alpha and MIP1-beta with either the corticosteroid or the antihistamine, compared to the pre-treatment levels. Chemokine downregulation was statistically significant in both groups of patients. These findings suggest that certain antihistamines may act as down-modulators of allergic inflammation, possibly through a negative regulation of the chemokines involved in activation and attraction of eosinophils. Our results suggest that clinical trials with long follow-ups may be useful in evaluating histamine-1 receptor antagonists as add-on therapy to steroids in the treatment of asthma.

Abstract
T-bet is a novel transcription factor regulating lineage commitment of T helper (Th) lymphocytes to a predominant Th1 phenotype. Previous studies on T-bet and asthma focused mainly on bronchial biopsy specimens. This study assessed the relationship between T-bet expression and levels of selected chemokines in the peripheral blood of asthmatics. Blood was collected from 24 steroid-naive asthmatics, 39 asthmatics on inhaled corticosteroid and 32 age- and sex-matched controls for assay of T-bet expression, specific IgE and chemokines (interferon-gamma inducible protein-10 (IP-10/CXCL10), monokines induced by interferon-gamma (MIG/CXCL9), monocyte chemotactic protein-1 (MCP-1/CCL2), regulated upon activation normal T cell expressed and secreted (RANTES/CCL5) and interleukin-8 (IL-8/CXCL8) levels. T-bet mRNA expression was assessed by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR). Chemokine levels were assessed by immunofluorescence flow cytometry. The mean (s.d.) age and forced expiratory volume in 1 s (FEV(1))% predicted of the asthmatics were 43 x 6 (14 x 6) years and 85 x 9 (20.0)%, respectively. The median (IQR) T-bet expression after normalization with beta-actin was suppressed in asthmatics versus controls [asthmatics 0 x 71 (0 x 59) versus controls 1 x 07 (1 x 14), P=0 x 03].The median (IQR) of plasma RANTES was elevated, whereas IP-10 was suppressed in asthmatics versus controls (RANTES: 13658 x 0 (13673 x 3) versus 6299 x 5 (19407 x 8) pg/ml, P=0 x 03; IP-10: 1047 x 6 (589 x 8) versus 1306 x 4 (759 x 9) pg/ml, P=0 x 001). There was a weak and negative correlation between T-bet expression and RANTES level in the asthmatics (r=-0 x 29, P=0 x 032). T-bet could be measured in peripheral blood and its expression was suppressed in asthmatics. This is in keeping with asthma being a predominantly Th2 disease and T-bet probably plays a role in the pathogenesis of asthma. Further studies are needed to explore the potential application of peripheral blood monitoring of T-bet.

Abstract
BACKGROUND Creeping fat represents a characteristic feature of Crohn's disease (CD) and adipose tissue is currently being recognized as a complex compartment secreting highly active molecules. Pro- or anti-inflammatory adipose tissue-derived secretory products (adipocytokines) might play a role in the pathogenesis of CD. METHODS Adipose tissue specimens were obtained from creeping fat contiguous to the involved intestine of 10 patients with CD. Mesenteric adipose tissue specimens resected in 13 patients with colon cancer (CC) and in seven patients with diverticulitis (DIV) served as controls. Three fat tissue specimens per well and n = 6-8 wells per patient were incubated ex vivo for 24 h. The release of regulated on activation, T-cell expressed and secreted (RANTES) and interleukin (IL)-10 into the supernatant was measured by ELISA. RESULTS Both RANTES and IL-10 secretion could be demonstrated from total adipose tissue explants. The RANTES secretion is increased from creeping fat in CD (3691 +/- 597 pg/g fat per 24 h) when compared to mesenteric adipose tissue from patients with CC (1690 +/- 191 pg/g fat per 24 h; P < 0.0001) or DIV (1672 +/- 336 pg/g fat per 24 h; P < 0.0001). In contrast, IL-10 secretion is downregulated significantly only in patients with DIV (1418 +/- 180 pg/g fat per 24 h; P = 0.016) when compared to CC patients (2368 +/- 259 pg/g fat per 24 h). Crohn's disease patients receiving steroids had a higher secretion rate of RANTES and IL-10. CONCLUSIONS Both RANTES and IL-10 secretion can be detected from mesenteric adipose tissue and from creeping fat. The elevated RANTES and IL-10 secretion from creeping fat in CD is not due to a CD-specific effect but caused by steroid treatment.

Abstract
BACKGROUND Preclinical studies have demonstrated that some second-generation antihistamines have anti-inflammatory effects. It is not known whether these effects are also demonstrable in vivo. In this study we investigated the effect of treatment with desloratadine (DL) on systemic inflammation and on nasal and bronchial mucosal inflammation after nasal allergen provocation (NP) in subjects with grass-pollen-allergic rhinitis and asthma. METHODS Twenty-six subjects with grass-pollen-allergic rhinitis and asthma were randomly allocated to 8 days of treatment with DL (n = 13) or placebo (n = 13) outside the grass pollen season. On day 7 they underwent nasal provocation with grass pollen allergen. Nasal and bronchial biopsies were taken for immunohistochemical evaluation, and blood samples were analysed. Rhinitis and asthma symptoms, peak nasal inspiratory flow and peak expiratory flow, were also measured at specified times. RESULTS The number of circulating eosinophils decreased during DL treatment, and there was a reduced increase in circulating eosinophils after NP in these subjects. There was also a significant reduction in early bronchial clinical response. There was no significant lessening in the severity of the nasal symptoms. Nasal and bronchial mucosal inflammation parameters did not alter under DL treatment. CONCLUSION These data suggest that treatment with DL reduces systemic eosinophilia and prevents the increase in circulating eosinophils after NP. DL also significantly reduces the early bronchial clinical response to NP. However, airway mucosal inflammation is not altered by 1 week of treatment.

Abstract
UNLABELLED Cetirizine is a selective, second-generation histamine H1 receptor antagonist, with a rapid onset, a long duration of activity and low potential for interaction with drugs metabolised by the hepatic cytochrome P450 system. Cetirizine was generally more effective than other H1 receptor antagonists at inhibiting histamine-induced wheal and flare responses. Cetirizine is an effective and well tolerated agent for the treatment of symptoms of seasonal allergic rhinitis (SAR), perennial allergic rhinitis (PAR) and chronic idiopathic urticaria (CIU) in adult, adolescent and paediatric patients. In adults with these allergic disorders, cetirizine was as effective as conventional dosages of ebastine (SAR, PAR, CIU), fexofenadine (SAR), loratadine (SAR, CIU) or mizolastine (SAR). This agent was significantly more effective, and with a more rapid onset of action, than loratadine in 2-day studies in environmental exposure units (SAR). In paediatric patients, cetirizine was as at least as effective as chlorphenamine (chlorpheniramine) [SAR], loratadine (SAR, PAR) and oxatomide (CIU) in the short term, and more effective than oxatomide and ketotifen (PAR) in the long term. Cetirizine was effective in reducing symptoms of allergic asthma in adults and reduced the relative risk of developing asthma in infants with atopic dermatitis sensitised to grass pollen or house dust mite allergens. It had a corticosteroid-sparing effect in infants with severe atopic dermatitis and was effective in ameliorating reactions to mosquito bites in adults. Cetirizine was well tolerated in adults, adolescents and paediatric patients with allergic disorders. In adult, adolescent and paediatric patients aged 2-11 years, the incidence of somnolence with cetirizine was dose related and was generally similar to that with other second-generation H1 receptor antagonists. Although, its sedative effect was greater than that of fexofenadine in some clinical trials and that of loratadine or fexofenadine in a postmarketing surveillance study. In infants aged 6-24 months, the tolerability profile of cetirizine was similar to that of placebo. Cetirizine did not have any adverse effects on cognitive function in adults, or cognitive function, behaviour or achievement of psychomotor milestones in paediatric patients. Cetirizine was not associated with cardiotoxicity. CONCLUSION Cetirizine is well established in the treatment of symptoms of SAR, PAR or CIU. It demonstrated a corticosteroid-sparing effect and reduced the relative risk of developing asthma in sensitised infants with atopic dermatitis. Cetirizine was effective in the treatment of allergic cough and mosquito bites; however, its precise role in these indications has yet to be clearly established. On the basis of its favourable efficacy and tolerability profile and rapid onset of action, cetirizine provides an important option for the treatment of a wide range of allergic disorders.

Abstract
The pathogenetic findings of rhinopathies show an increase in infiltrating cells including eosinophils. RANTES is a beta chemokine in which the cysteines are adjacent (C-C), and it attracts and activates eosinophil. We hypothesize that RANTES is locally produced within the nasal polyp microenvironment and is responsible for the inflammatory cell recruitment present in nasal polyposis. To test this hypothesis, we evaluated nasal polyps and mucosa from allergic and control, non-allergic patients for RANTES content. The relative levels of RANTES and MCP-1 protein in tissue homogenates were quantified using enzyme-linked immunosorbent assay technology, and quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) tests for RANTES and MCP-1 mRNA expression were performed. The results indicate that RANTES expression and production increase in nasal mucosa (septal and turbinate portions) of allergic patients compared to the same mucosa in non-allergic patients. In allergic patients, RANTES levels of nasal polyp homogenates were nearly 12-fold higher than the RANTES levels in mucosa homogenate. In this study, we hypothesize that the particular anatomic structure and physiologic function of the turbinates are more involved in the pathogenesis of rhinitis and may undergo polypoid degeneration in allergic rhinitis than any other anatomical structure of the nose. Our data suggest that RANTES is more involved than MCP-1 in recruiting inflammatory cells in rhinological disease and may reflect the degree of local inflammation as consequence of the specific chemoattractant properties of RANTES. The level of RANTES in nasal polyps could be important in the development of the pathological state.

Abstract
It has been reported that the CD4+ T cell is a very important source of interleukin 10 (IL-10), while CD8+ cells produce low amounts. IL-10 exerts several immune stimulating, as well as inhibitory effects. There are at least five novel human IL-10 family-related molecules: IL-19, IL-20, IL-22, IL-24, and IL-26. Activated T cells produce IL-19, IL-22 and IL-26, while IL-24 is produced by activated monocytes and T-cells. IL-20 induces cheratin proliferation and Stat-3 signal transduction pathway, while IL-22 induces acute-phase production by hepatocytes and neonatal lethality with skin abnormalities reminiscent of psoriasic lesions in humans. In addition, IL-22 mediates inflammation and binds class II cytokine receptor heterodimers IL-22 RA1/CRF2-4. This cytokine is also involved in immuno-regulatory responses. IL-26 (AK155) is a novel cytokine generated by memory cells and is involved in the transformed phenotype of human T cells after infection by herpes virus. All these new IL-10 subfamily member cytokines are strongly involved in immune regulation and inflammatory responses.

Abstract
The plant amino acid L-mimosine has recently been suggested to inhibit cells at a regulatory step in late G1 phase before establishment of active DNA replication forks. In addition, L-mimosine is an extremely effective inhibitor of DNA replication in chromosomes of mammalian nuclei. In this work, the effect of L-mimosine on chronic inflammation induced by dorsal injections of 0.2 ml of a 1:40 saturated crystal solution of potassium permanganate in mice, was studied. Seven days afterwards, all mice developed a subcutaneous granulomatous tissue indicative of chronic inflammatory response at the site of infection. The intraperitoneal administration of L-mimosine (200 microg/dose) to the potassium permanganate treated mice for 5 consecutive days (the first at the same time of inoculation of the KMnO4), produced a significant decrease in size and weight of the granuloma when compared to mice not treated with L-mimosine (controls). In addition, in all mice treated with L-mimosine, there was a strong inhibition of tumor necrosis factor alpha that was revealed in the serum (P<0.05) and in the minced granulomas. Interleukin-6 was not detected in the serum of treated and untreated mice. These findings show for the first time, that L-mimosine may have an anti-inflammatory effect on chronic inflammation and an inhibitory effect on tumor necrosis factor alpha and interleukin-6 generation in supernatant fluids of minced granulomas.

Abstract
Insufficient data exist to evaluate the comparative effects of inhaled corticosteroids (ICS) versus leukotriene receptor antagonist (LTRA) on airway inflammation and quality of life (QoL). The aim of the study was to compare the effectiveness of montelukast compared to budesonide at different doses on QoL and bronchial reactivity in mild-asthmatic adult patients. 45 subjects with bronchial asthma were randomly assigned to a different treatment and divided in 3 treatment groups: A: 400 mg of budesonide twice a day; B: 10 mg of montelukast daily; C: 10 mg of montelukast daily plus 400 mg of budesonide twice a day. At the beginning of the study and at the end of the treatment period (16 weeks) all patients underwent complete clinical evaluation, pulmonary function testing and methacholine challenge test (MCHt). In group A the increase from baseline was 153.4&#x0025;, in group C was 133.2&#x0025;, and in group B 247.7&#x0025;, the latter increase being statistically significant compared to that in the other 2 groups (p&#x003C; 0.005 Wilcoxon test). In all domains the improvement in quality of life in the group treated with montelukast (group B) was significantly greater than that in the group treated with both medications (group C): in particular, the improvement was consistent in the symptoms (p&#x003C; 0.01) and emotions (p&#x003C; 0.01) domains, and weaker in the physical activity (p&#x003C; 0.05). A similar difference was observed between group B and A, but only in the symptoms (p&#x003C;0.01), emotions (p&#x003C;0.01), and environmental stimuli domains (p&#x003C;0.05). The personal perception of their own disease is important for a correct therapeutic management of asthma. In order to optimize the treatment, a complete adherence of the patient to the treatment itself is required, to be achieved through simplification of therapeutic schedule and easy administration of medications. Montelukast may be considered a valid alternative in the treatment of mild-persistent asthma, both for the clinical and functional benefits and for the great advantage of the once-daily dosage, which consistently improves the compliance with the chronic treatment of the disease.
