Objective: This study is an exploration of the relationship between chemical industrial environment and allergic skin diseases.
Methods: In this retrospective analysis, 200 patients with allergic skin diseases who worked or lived in a chemical industrial zone and were admitted in our hospital between January 2018 and January 2020 were enrolled as Group A. Besides, 500 patients with allergic skin disease who lived in Zhenhai New District, five kilometers away from the chemical radiation zone, were selected as Group B. The specific immunoglobulin E (IgE) levels were determined by Western blotting. The allergen positivity, as well as allergen positivity between different age, sex and body mass index (BMI) were compared between the two groups. The positive food-specific allergen IgE antibody (sIgE) and positive inhalational sIgE were compared between the two groups.
Results: The positive rate of total IgE and inhalational sIgE in Group A was higher than that in Group B (P<0.05), while there was no significant difference in positive rate in food sIgE between the two groups (P>0.05). In Group A, the differences in positive rates of total IgE, food-induced sIgE and inhalational sIgE were not significant between patients with different ages, sexes and BMI (P>0.05). There was no significant difference between the two groups in sIgE positive rates of wheat, mango, soybean/peanut/cashew nut combination, limb/beef combination, crab/shrimp/fish combination, milk and egg white (P>0.05). The positive rates of inhalational sIgE in tree combination and dust mites/household dust mites combination in Group A were higher than those in Group B (P<0.05), but had no significant difference between the two groups in the positive rates of inhalational sIgE in Humulus japonicus, mold combination 1, cockroach, cat/dog hair combination, and ragweed/artemisia combination (P>0.05).
Conclusion: Chemical industrial environment is closely associated with allergic dermatosis, and the positive rate of total IgE and inhalational sIgE increases significantly in patients living there.

Article Synopsis
- - The study analyzed serum allergen-specific IgE (sIgE) in 3,822 patients with respiratory and skin diseases in Shanghai over one year to help understand and improve the diagnosis and treatment of allergies in the region.
- - Results revealed that 88.4% of patients tested positive for at least one allergen, with 72.9% exhibiting multiple allergy sensitivities; the most common allergens included house dust mites, milk, fungi, and certain tropical mites.
- - Statistical analysis indicated that certain allergens like cat dandruff were more prevalent in respiratory diseases, while food allergens like shrimp and crab showed lower positivity rates, providing insights into the allergen distribution for targeted prevention strategies.

Article Synopsis
- The study examined changes in specific IgE (sIgE) test results for common allergens in children hospitalized from 2019 to 2023 to assist in diagnosing allergic diseases.
- A total of 44,633 test results were analyzed, split between food and inhaled allergens, revealing significant yearly increases in positive rates for both categories.
- Age-related differences in sensitization patterns were observed, with egg white being the most common food allergen in infants, and peanut allergies becoming prevalent in older children and adolescents.

The development of rapid analysis of human serum for the presence of allergen-specific Immunoglobulin E (IgE) is currently important. Consequently, we developed two types of three-dimensional (3D) protein biochips. The first one is a 3D hydrogel biochip containing hydrogel droplets with protein molecules (allergens, immunoglobulins and others).

Objective: To assess the characteristics of total immunoglobulin E (IgE) and allergen-specific IgE (sIgE) to 20 common allergens in 154 patients with atopic dermatitis (AD). To assess the correlation of clinical food allergy with positive food allergens' sIgE results. We further discuss the significance of IgE as a potential biomarker for AD disease severity.

Article Synopsis
- Allergic diseases are on the rise, posing a significant health threat, particularly in Sichuan province, China, where a study analyzed allergen-specific immunoglobulin E (sIgE) levels in over 12,000 patients suspected of having allergies.
- The study found that D1 and D2 allergens had the highest sensitization rates (22.97% and 23.33%, respectively), with men showing a higher rate of sensitization compared to women, and most patients with allergic rhinitis and asthma were sensitized to these allergens.
- This research highlights the need for better identification and management of allergens, which can aid in preventing and treating allergic diseases.
