Abstract Female genital tract chronic inflammation is common in clinics; the pathogenesis is not fully understood yet. House dust mite (HDM) involves the pathogenesis of many chronic diseases in human. This study aims to identify HDM-specific allergic response in the cervix of patients with cervical inflammation. Patients (n=80) with chronic cervicitis (CC) and non-CC control (NC) subjects (n=80) were recruited into this study. Vaginal lavage fluids (VLF) were collected from CC patients and NC subjects. Cellular components and fluid part of VLF were separated by centrifugation, and analyzed by flow cytometry and enzyme-linked immunosorbent assay. We found that a portion (52 out of 80) of CC patients responded to HDM, manifesting positive skin prick test, and HDM-specific IgE and IgG was detected in the VLF (designated CCp patients). VLF of CCp patients showed a Th2 dominant profile. HDM-specific Th2 cells were detected in VLF in CCp patients. Exposure to HDM in the culture induced proinflammatory cytokine release from CCp VLF CD4 + T cells. Exposure to CCp VLF CD4 + T cell-conditioned medium induced de novo Th2 response. Direct exposure to HDM induced allergic response in the cervix of CCp patients. In summary, a portion of CC patients respond to HDM challenge in the cervix. Exposure to HDM induces an allergy-like response in the cervix of CCp patients.

Abstract Background Serine peptidase inhibitor, clade B, member 10 (SERPINB10) contributes to allergic inflammation in asthma. However, its role in the T-helper type 2 (Th2) response of allergic asthma is not known. The goal of this study was to unveil the function of SERPINB10 in the Th2 response of allergic asthma and the mechanism by which SERPINB10 affects the viability of Th2 cells. Methods Th2 cytokines and serum levels of house dust mite (HDM)-specific IgE in bronchoalveolar lavage fluid were examined by ELISA in an HDM-induced asthma model. The number and apoptosis of Th1 and Th2 cells in mouse lungs were measured by flow cytometry. Naïve CD4 T cells from patients with asthma were cultured under appropriate polarizing conditions to generate Th1 and Th2 cells. SERPINB10 expression in polarized Th1 and Th2 cells was quantified by real-time reverse transcription-quantitative polymerase chain reaction. SERPINB10 expression was knocked down in human CD4 T cells with lentivirus. Results Knockdown of SERPINB10 expression significantly diminished HDM-induced Th2 cytokine secretion and level of HDM-specific IgE. After HDM exposure, SERPINB10-knockdown mice had diminished numbers of Th2 cells, but similar numbers of Th1 cells, compared with those in negative-control mice. Th2 cells of SERPINB10-knockdown mice were more susceptible to apoptosis than that of control mice. Stimulating T-cell receptors (TCRs) with anti-CD3 antibody caused upregulation of SERPINB10 expression in polarized Th2 cells, but not polarized Th1 cells. Knockdown of SERPINB10 expression resulted in fewer numbers and greater apoptosis of polarized Th2 cells. Conclusion Our results suggest that SERPINB10 may contribute to allergic inflammation and the Th2 response of asthma by inhibiting the apoptosis of Th2 cells.

Is Atopy Related to Neuroticism, Stress, and Subjective Quality of Life?Different psychosocial characteristics have been associated with allergic disorders. The aim of this study was to examine whether atopic constitution and reports of allergic symptoms were related to personality trait of neuroticism, exposure to stressful life events and estimates of quality of life. Atopy was determined by skin prick test and reports of nasal and pulmonary allergy-related symptoms. Actively working individuals of both genders took part in the study (n=145, age range: 20 to 66 years). The participants were divided in three groups. The first group was composed of those with negative skin prick test and without symptoms (n=57), the second of those with positive skin prick test but without symptoms (n=28), and the third of those with positive skin prick test and symptoms (n=60). The groups did not differ significantly in neuroticism, exposure to stressful life events, or quality of life. Women reported more pronounced neuroticism and anxiety, higher exposure to stressful life events, and were less satisfied with their environment than men. In our sample of active workers we found no association of neuroticism, exposure to stressful life events, and quality of life with atopy and allergic symptoms.

BACKGROUND: Allergic rhinitis is one of the most common allergic diseases and characterised by sneezing, rhinorrhea, nasal congestion and nasopharyngeal itching. Subcutaneous immunotherapy (SCIT) for specific allergens is an effective treatment and induces the inhibitory effect of T regulatory lymphocytes and decreases clinical symptoms in allergic rhinitis.AIM: In this study effect of subcutaneous immunotherapy with specific allergens on clinical symptoms and T regulatory and T Helper cells cytokines, in patients with allergic rhinitis are evaluated.METHODS: In this study, 30 patients with moderate to severe allergic rhinitis according to clinical criteria and positive skin prick test for aeroallergens were selected and treated by SCIT. Clinical symptoms and T cells cytokines IL4, IL17, IFN gamma, TGF beta, GITR, FOXP3 and IL-10 (by RT-PCR) were evaluated before and one year after initiation of treatment.RESULTS: Thirty (30) patients with allergic rhinitis at age range 15-45 years old were treated by SCIT, and 23 (14 female, 9 male) patients continued the study, and 7 patients did not continue treatment. After immunotherapy, clinical symptoms decreased significantly. The specific cytokines TGF beta and IL10 levels increased and changes were statistically significant. (Respectively P = 0.013 and P = 0.05) The IL17 level was also increased, but not statistically significant. (P = 0.8) IFN gamma, IL4, GITR, FOXP3, all decreased, but the changes were not statistically significant (P > 0.05).CONCLUSION: Subcutaneous Immunotherapy for specific allergens decreases clinical symptoms in patients with allergic rhinitis and induces tolerance in T lymphocytes, especially by increasing T regulatory cells cytokines, TGF beta and IL10.

Parental Reports

Background Food allergy is common in children and its prevalence is generally on the rise. Imprecise parental reports about reactions to particular foods can lead to unnecessary restrictions. Since children have specific growth requirements, such nutritional restrictions may have disturbing effects on children’s growth and development.Objective To compare parental reports on food reactions to skin prick test results in their children.Method Retrospective, cross sectional study using patient’s medical record data during one-year study period. Data were analyzed manually and statistically, to assess the degree of agreement (Kappa’s coefficient) and significance (P).Results We collected data from 154 subjects aged 0-18 years. For every allergen assessed, parents reported more food reactions than positive skin prick test results. Allergy incidence were caused, in order, by cow’s milk and chicken (25.3%), eggs (22.1%), chocolate (20.1%), fruits (14.3%), seafood (13%), and saltwater fish (1.9%). Kappa coefficient are all poor (<0.2) and P value are all >0.05 except for chicken (P=0.02).Conclusion Most parents tend to overestimate which food cause reactions in their children, as reactions reported were not necessarily allergenic. Therefore, every patient experiencing allergy reactions should undergo skin prick testing to confirm the possibility of allergy.

Background Atopy has been suggested in the development of chronic rhinosinusitis (CRS), as allergic rhinitis (AR) is common coexisting disease in pediatric and adult patients with CRS. The contribution of AR to CRS is less clear till date. Objectives The objectives of this study were to determine atopic profile of children with CRS and impact of atopic status on disease severity and quality of life. Methods One hundred ten patients, aged between 7 and 18 years of age, diagnosed with CRS based on history, detailed clinical examination including nasal endoscopic examination were included in this cross-sectional study. Scoring of CRS was done according to Lund Mackay Endoscopic Appearance Score. Patients underwent skin prick test against 65 common aeroallergens (1:10 w/v, 50% glycerinated) for evidence of atopy. SN-5 Sinus and Nasal Quality of Life Survey was used to assess the quality of life in the study subjects. Results Positive skin prick test to at least one of the common aeroallergens was present in 58 (52.7%) patients. Most common aeroallergen sensitivity was seen with insects in 48 (43.6%) patients. Patients of CRS with atopy had higher mean Lund Mackay endoscopic score and SN-5 score than nonatopic patients which was statistically significant. Conclusion In conclusion, we recommend that testing for aeroallergen sensitivity and assessment of quality of life should be included in the protocol for diagnosis and management of pediatric patients with CRS. Early diagnosis and treatment of allergy may halt the progression of CRS and also the development of asthma and other allergic multimorbid disorders.

Rare Manifestation

Eosinophilic ascites, owing to serosal involvement, is a very rare manifestation of eosinophilic gastroenteritis in children, especially when it occurs with muscular involvement in the absence of mucosal disease, which may be confirmed by endoscopic ultrasonography. An 11-year-old girl, presenting with massive eosinophilic ascites and colicky abdominal pain with peripheral eosinophilia, raised IgE levels and positive skin prick test, had such investigation which confirmed the presence of muscle layer thickening of both stomach and small bowel. She responded well to steroids and montelukast.

Protein Contact Dermatitis

Abstract Protein contact dermatitis (PCD) often presents as chronic hand eczema (CHE) with an immediate hypersensitivity to protein proved by a positive skin prick test or by the presence of specific immunoglobulin E. This is frequently induced by occupational exposure to proteins in food workers, farmers, animal breeders, veterinarians and healthcare professionals. While skin barrier impairment is crucial in the pathogenesis of PCD, methods to assess skin barrier function such as trans-epidermal water loss and stratum corneum hydration are not widely used in clinical settings. We describe the diagnostic workup of occupational PCD due to Argentinean shrimps and discuss how the use of skin bioengineering methods including assessment of corneocytes morphology by Scanning Electron Microscopy provides with insightful information on skin barrier function. Diagnosis of PCD is time-consuming and a multidisciplinary team contributes to early diagnosis and proper occupational rehabilitation.
