Abstract Background Shrimp allergy is a growing problem among the European population. TSLP, IL-25 and IL-33 are involved in the pathophysiology of allergic diseases, including asthma and atopic dermatitis, as they activate the Th2-dependent immune response. Methods Thirty-seven patients (18 male and 19 female) with a positive history of symptoms associated with shrimp consumption were selected. All patients had blood samples taken to assess the concentration of allergen-specific IgE (sIgE) to house dust mites (HDM) and shrimp (Singleplex, quantitative method with cut off value > 0,35 kAU/L) as well as the level of allergen components using the ImmunoCap ISAC method (Microarray test, semi-quantitative with cut off value > 0,3 ISU-E). The concentrations of TSLP, IL-25 and IL-33 in the patients’ blood serum was assessed using the ELISA method (Cusabio). Twenty patients with negative allergy history of allergic disease tests were included in the control group. Results Among the 37 shrimp-allergic patients, ImmunoCap ISAC was identified the presence of sIgE to the available shrimp allergen components in only 14 cases (37.8%). TSLP and IL25 levels were significantly higher in the study group. No statistically significant correlation was found between the concentration of analyzed alarmins and the concentration of sIgE level to shrimp or HDM between the study and control groups. No statistically significant correlation was found between poly-sensitization occurring in patients and levels of TSLP, IL-25 and IL-33 . Conclusion In shrimp-allergic patients, the concentrations of TSLP and IL-25 were significantly higher than in the control group (1.33 vs. 0.49 and 157 vs. 39.36, respectively). There was no correlation between the concentrations of TSLP, IL-25 and IL-33 and the concentration of sIgE in the patients or the number of allergen components that the patients were sensitized to.

BACKGROUND: Alopecia areata is a non-scarring hair loss, which typically starts quickly. Atopy is one of the possible predisposing risk factors for this condition.AIM: This study aimed to evaluate the prevalence of thyroid disease, atopic dermatitis and allergic diseases in children with alopecia areata and compare the results with healthy individuals.METHODS: This case-control study was conducted on 50 patients with alopecia areata, diagnosed by a dermatologist, and 150 healthy individuals as the control group. Participants filled the questionnaires, and necessary tests were performed.RESULTS: In this study, the mean age of the participants was 2.55 ± 14.26 and 3.19 ± 11.92 in the case and control groups, respectively. Prevalence of asthma was 22% in the case group and 12.5% in control group (P = 0.109). Also, allergic rhinitis and eczema were observed in 20% and 22% of the subjects of the case group, whereas they were reported to be 8% and 10% in the control group (PV = 0.03 and 0.175, respectively). Moreover, 28% and 8% of the participants in the case and control groups had a family history of atopy and allergic disorders, respectively (P = 0.046). A significant difference was observed between the two groups regarding gender, type of delivery and contact with animals.CONCLUSIONS: According to the results of this study, a significant association was observed between the prevalence of alopecia areata and atopic conditions, such as allergic rhinitis and history of atopic dermatitis.

Abstract Background: Seasonal (SAC) and perennial allergic conjunctivitis (PAC) are the most common allergic conjunctivitis. House dust mites are the most common sensitizing agents for SAC and PAC. This study aimed to explore the risk factors of allergic conjunctivitis in children. Methods: The study recruited 176 children suffering from SAC or PAC and 131 normal control subjects in southwest of China. A questionnaire was provided to all the subjects. Several eye exams were also performed. All the subjects received the skin prick test (SPT). Then we analyzed the scores of the symptom, sign and the corneal fluorescein staining, the questionnaire data and the SPT results. Results: The percent of the ever breast-fed in the case group was lower than that in control group (P<0.05). The rate of parental allergy history in the case group was higher than that of the control group (P<0.01). The scores of both ocular symptoms and signs had significant correlation to the clinical course (P<0.05), but there was no relationship between these scores and the results of SPT (P>0.05). The rate of parental allergy history in the case group was higher than that in the control group (P<0.01 both in father and mother). Compared with control group, the case group was more likely related to other systemic allergic disease (P<0.01). Conclusion: Allergic conjunctivitis might coexist with a variety of allergic diseases. Breastfeeding can effectively reduce the incidence of allergic conjunctivitis, especially for those children whose parents had history of allergic diseases.

Background Levels of specific IgE (sIgE) against allergen components can be assessed using multiplex assays or with highly sensitive, quantitative methods. The aim of this study was to compare the sensitivity and specificity of different immunological methods for diagnosis of shrimp allergy. Methods Twenty patients with positive skin prick tests for frozen tiger shrimp were selected for further examination. Blood samples were taken to assess concentrations of sIgE against the house dust mites Dermatophagoides pteronyssinus and D. farinae, shrimp allergen extract, allergen components Der p 1, Der p 2 and Pan a 1 (ImmunoCap), and the ImmunoCap ISAC 112 panel. Results All patients had elevated levels of sIgE against shrimp and D pteronyssinus. Eight patients were sensitized to Pen m 1, three patients were sensitized to Pen m 2, and two patients were sensitized to Pen m 4 (ISAC). ImmunoCap ISAC detected shrimp sensitization in 50% of patients. There was a strong correlation between concentrations of sIgE against Pen m1 and Der p 10 detected by ImmunoCap. Conclusions The singleplex ImmunoCap system remains the reference diagnostic method, but in the case of shrimp allergy ImmunoCap ISAC provided better insight into patient allergen profiles.

Background: Serum Peanut-specific-IgE (PN-sIgE) and peanut-component-resolved-diagnostics (CRD) are often ordered simultaneously in the evaluation for peanut allergy. Results often guide the plans for peanut oral challenge. However, the clinical utility of CRD at different total PN-sIgE levels is unclear. A commonly used predefined CRD Ara h2 cutoff value in the literature predicting probability of peanut challenge outcomes is 0.35kUA/L. Objective: To examine the utility of CRD in patients with and without a history of clinical reactivity to peanut (PN). Methods: This was a retrospective chart review of 196 children with PN-sIgE and CRD testing, of which, 98 patients had a clinical history of an IgE-mediated reaction when exposed to PN and 98 did not. The Fisher's exact test was used to assess the relationship between CRD and PN-sIgE at different cutoff levels, McNemar test and Gwet’s approach (AC1 statistic) were used to examine agreement between CRD and PN-sIgE, and logistic regression was used to assess differences in the findings between patients with and without reaction history. Results: Ara h 1, 2, 3, or 9 (ARAH) levels ≤0.35 kUA/L were significantly associated with PN-sIgE levels <2 kUA/L rather than ≥2 kUA/L (p < 0.0001). When the ARAH threshold was increased to 1 kUA/L and 2 kUA/L, these thresholds were still significantly associated with PN-sIgE levels of <2, <5, and <14 kUA/L. These findings were not significantly different in patients with and without a history of clinical reactivity. Conclusion: ARAH values correlated with PN-sIgE. Regardless of clinical history, ARAH levels are unlikely to be below 0.35, 1, or 2 kUA/L if the PN-sIgE level is >2 kUA/L. Thus, if possible, practitioners should consider PN-sIgE rather than automatically ordering CRD with PN-sIgE every time. Laboratory procedures that allow automatically and reflexively adding CRD when the PN-sIgE level is ≤5 kUA/L can be helpful. However, further studies are needed in subjects with challenge-proven PN allergy.

Objectives: Molar pregnancy is the gestational trophoblastic disease and impact on the women’s health. It has several complications such as toxicity, infection, bleeding. Molar pregnancy also has high risk of choriocarcinoma which can be dead. Aim: To assess the risks of molar pregnancy. Materials and Methods: The case control study included 76 molar pregnancies and 228 pregnancies in control group at Hue Central Hospital. Results: The average age was 32.7 ± 6.7, the miximum age was 17 years old and the maximum was 46 years old. The history of abortion, miscarriage in molar group and control group acounted for 10.5% and 3.9% respectively, with the risk was higher 2.8 times; 95% CI = 1.1-7.7 (p<0.05). The history of molar pregnancy in molar pregnancy group was 9.2% and the molar pregnancy risk was 11.4 times higher than control group (95% CI = 2.3-56.4). The women having ≥ 4 times births accounted for 7.9% in molar group and 2.2% in control group, with the risk was higher 3.8 times, 95% CI= 1.1-12.9 (p<0.05). The molar risk of women < 20 and >40 years old in molar groups had 2.4 times higher than (95% CI = 1.1 to 5.2)h than control group. Low living standard was 7.9% in molar group and 1.3% in the control group with OR= 6.2; 95% CI= 1.5-25.6. Curettage twice accounted for 87.5%, there were 16 case need to curettage three times. There was no case of uterine perforation and infection after curettage. Conclusion: The high risk molar pregnancy women need a better management. Pregnant women should be antenatal cared regularly to dectect early molar pregnancy. It is nessecery to monitor and avoid the dangerous complications occuring during the pregnancy. Key words: Molar pregnancy, pregnancy women

The prevalence of allergic diseases is increasing worldwide. It is estimated that more than 30% of the world population is now affected by one or more allergic conditions and a high proportion of this increase is in young people. The diagnosis of allergy is dependent on a history of symptoms on exposure to an allergen together with the detection of allergen-specific IgE. Accurate diagnosis of allergies opens up therapeutic options. Allergen specific immunotherapy is the only successful disease-modifying therapy for IgE-mediated allergic diseases. New therapeutic strategies have been developed or are currently under clinical trials. Besides new routes of administration, new types of allergens are being developed. The use of adjuvants may amplify the immune response towards tolerance to the antigens. In this review, we analyze different antigen-specific immunotherapies according to administration route, type of antigens and adjuvants, and we address the special case of food allergy.

ABSTRACT Objective: To investigate whether there is an association between suicidal ideation (SI) and allergic diseases in adults. Methods: This was a comparative cross-sectional study involving individuals ranging from 20 to 50 years of age recruited from a university hospital in the city of Guadalajara, Mexico. We included patients with a confirmed diagnosis of allergic asthma, those with a confirmed diagnosis of allergic rhinitis, and healthy controls. All subjects completed the Beck Depression Inventory-II (BDI-II), which includes an item that evaluates the presence of suicidal thoughts or desires within the last two weeks, in order to identify SI. Results: The sample comprised 115 patients with allergic asthma, 111 patients with allergic rhinitis, and 96 healthy controls. The number of individuals identified with SI in the three groups were, respectively, 17 (14.8%), 13 (11.7%), and 8 (8.3%). Regarding the presence of SI, no statistically significant association was found in the allergic asthma group (OR = 1.98; 95% CI: 0.78-4.64; p = 0.154) or in the allergic rhinitis group (OR = 1.46; 95% CI: 0.58-3.68; p = 0.424) when they were compared with the control group. However, the presence of depression was associated with SI in the three groups: allergic asthma (OR = 12.36; 95% CI: 2.67-57.15; p = 0.001); allergic rhinitis (OR = 6.20; 95% CI: 1.66-23.14; p = 0.006); and control (OR = 21.0; 95% CI: 3.75-117.36; p < 0,001). Conclusions: In comparison with the control group, no association was found between SI and the groups with allergic diseases. In contrast, there was association between SI and depression in the three groups.

Abstract Background: Brucellosis is one of the most frequently occurring zoonotic diseases of veterinary and a public health problem in developing countries. It affects human and animal health and has measurable effects on the productive and reproductive performance of livestock. Therefore, the main purpose of this study was to develop a community-based intervention program for brucellosis prevention and control. A two-arm parallel cluster randomized controlled trial investigated the effectiveness of the program over six months in a rural population in Ahar, East Azerbaijan, Iran. A total of 16 village health houses were randomly allocated to the intervention and the control groups (eight per arm), and 400 participants were recruited via household health records in the health houses. The PRECEDE model, which is an acronym for Predisposing, Reinforcing and Enabling Constructs in Educational Diagnosis and Evaluation, was used to design, implement, and evaluate the brucellosis prevention and control program. Knowledge, attitudes, self-efficacy, social support, environmental enabling, and behavioral factors were measured at the baseline and the six-month follow-up. A generalized mixed effects model was used to analyze data. Results: The mean ages (SD) of the intervention and control group respondents were 35.9 (11.87) and 37.28 (11.04) years, respectively. After the six-month intervention, significant between-group differences were found on all PRECEDE variables, adjusted for education, history of brucellosis, and family history of brucellosis. Conclusion: There is a need to consolidate collaborative health and veterinary sector efforts, as well as increase regular vaccination practices and financial resources to support farmers willing to slaughter animals and/or offer slaughter facilities. The present study was able to demonstrate which educational and ecological factors influence behaviors and environments related to brucellosis and, as such, provide evidence of the effectiveness of interventions based on the PROCEDE model.

Background. Allergic diseases are the most prevalent chronic diseases in the developed countries. It is believed that early allergic sensitization and respiratory viral infections play an important role in the development of allergic diseases and asthma. Methods. The current study investigated the correlation between asthma, allergy, and various markers – allergen-specific IgE, IgG4 and IgA, ECP, IgM, and IgG antibodies against respiratory viruses hRSV and hPIV1-4 – in blood serum samples from 80 children (mean age 5.2 years) recruited from the Lithuanian birth cohort. Children were divided into three groups according to their diagnosis: asthma (n = 25), allergy without asthma (n = 14), and control group (n = 41). Results. Based on retrospective data, airway infections and bronchitis by the age of two years were associated with asthma in later childhood. The presence of IgM and IgG antibodies against hRSV and hPIV1–4 at the age of five years were not associated with asthma and allergy: a high rate of persistent or past respiratory viral infections was revealed in all three groups. Among allergic children, increased levels of allergen-specific IgE and d1-specific IgG4 were determined. Conclusion. The current study provides new insights into the relationships between allergic sensitization and respiratory virus infections in children.

Ocular and ophthalmological adverse effects may be seen in β-thalassemia major (BTM) patients treated with regular blood transfusions and iron-chelating agents. We hypothesized that olfactory dysfunction may be present in this population. In this study, we aimed to investigate olfactory dysfunction in patients with BTM and determine the etiological factors. A total of 43 patients with BTM were included in the study. Forty-three patients without any nasal complaints, history of facial trauma, or nasal surgery were included as the controls. All participants had nasal endoscopy. The iron-chelating agents used, their duration of use, as well as hemoglobin and ferritin levels of the BTM patients were recorded. Sniffin’ Sticks test (SST) was used to assess olfactory functions, and BTM and control groups were compared for the results. The correlations of SST scores with the other study parameters were analyzed. Eight (18.6%) of 43 patients in the BTM group had hyposmia while none of the patients in the control group had hyposmia ( P < .001). Older age, low-hemoglobin level, and longer use of deferoxamine were found to be correlated with olfactory dysfunction. Olfactory dysfunction may be seen in BTM patients treated with iron-chelating agents. The results of this study suggest that screening for olfactory function may be needed in routine follow-up of BTM patients.
