Background: The German Therapy Allergen Ordinance (TAO) triggered an ongoing upheaval in the market for house dust mite (HDM) allergen immunotherapy (AIT) products. Three HDM subcutaneous AIT (SCIT) products hold approval in Germany and therefore will be available after the scheduled completion of the TAO procedure in 2026. In general, data from clinical trials on the long-term effectiveness of HDM AIT are rare. We evaluated real-world data (RWD) in a retrospective, observational cohort study based on a longitudinal claims database including 60% of all German statutory healthcare prescriptions to show the long-term effectiveness of one of these products in daily life. Aim of this analysis was to provide a per product analysis on effectiveness of mite AIT as it is demanded by international guidelines on AIT.
Methods: Subjects between 5 and 70 years receiving their first (index) prescription of SCIT with a native HDM product (SCIT group) between 2009 and 2013 were included. The exactly 3:1 matched control group received prescriptions for only symptomatic AR medication (non-AIT group); the evaluation period for up to 6 years of follow-up ended in February 2017. Study endpoints were the progression of allergic rhinitis (AR) and asthma, asthma occurrence and time to the onset of asthma after at least 2 treatment years.
Results: In total, 892 subjects (608 adults and 284 children/adolescents) were included in the SCIT group and 2676 subjects (1824 adults and 852 children/adolescents) in the non-AIT group. During the follow-up period after at least 2 years of SCIT, the number of prescriptions in the SCIT group was reduced by 62.8% (p < .0001) for AR medication and by 42.4% for asthma medication (p = .0003). New-onset asthma risk was significantly reduced in the SCIT vs non-AIT group by 27.0% (p = .0212). The asthma-preventive effect of SCIT occurred 15 months after start of the treatment. In the SCIT group, the time to onset of asthma was prolonged compared to the non-AIT group (p = .0010).
Conclusion: In this first product based RWD analysis on SCIT with a native HDM product, patients aged 5 to 70 years benefited from AIT in the long term in terms of reduced progression of AR and asthma after at least 2 years of treatment. The effects seemed to last for up to 6 years after treatment termination. A significantly reduced risk of asthma onset was observed, starting after 15 months of treatment.

Background: The safety of aluminium (Al) exposure from medicinal products for subcutaneous allergen immunotherapy (SCIT) is still under debate due to their administration in many doses over years. Especially for children, model-informed risk assessment is urgently needed in the absence of clinical study data.
Methods: We applied a physiologically-based toxicokinetic Al model for simulation of Al exposure from various SCIT scenarios in children (5 and 10 years) compared to adults (35 years) in addition to continuous Al exposure from dietary intake.

Potato blight is a serious disease that affects potato crops and leads to substantial agricultural and economic losses. To enhance detection accuracy, we propose Bayesian Optimized CNN Weighted Ensemble Potato Blight Detection, a deep learning-based approach that optimizes CNN models through Bayesian optimization and ensemble learning. In the proposed study, extensive experiments were conducted to develop an optimized Bayesian Weighted Ensemble CNN model for the detection of potato leaf blight.

Introduction: House dust mite (HDM) sensitization plays a key role in allergic rhinitis (AR) and asthma, yet the clinical value of component-resolved diagnostics (CRD) and immunological markers in children undergoing subcutaneous immunotherapy (SCIT) remains unclear. This study aimed to investigate specific immunoglobulin E (sIgE) and sIgG4 profiles against HDM components to distinguish HDM-induced AR from asymptomatic sensitization and to evaluate the longitudinal changes following SCIT in symptomatic patients, exploring their potential as biomarkers for selecting candidates for SCIT.
Methods: A total of 72 HDM-sensitized participants were included: 46 symptomatic AR patients (with/without allergic asthma) and 26 asymptomatic individuals.

Circadian rhythm, as a homeostatic tool of biological life, plays a vital role in regulating human physiology, metabolism, endocrinology, and emotional and cognitive behaviour. A disrupted circadian rhythm, marked by age-related alterations such as decreased variation in sleep-wake patterns and instability in the timing of these patterns, can worsen age-related problems such as increased oxidative stress and inflammation. Advancing age is associated with anomalies in the redox balance, gradual alterations in physiological functions and deregulation of various metabolic pathways.

Background: Dupilumab for patients with moderate-to-severe atopic dermatitis (AD) does not maintain efficacy after discontinuation, while subcutaneous immunotherapy (SCIT) with enduring efficacy may be useful as a complementary treatment to dupilumab.
Objective: This study aimed to compare the efficacy between dupilumab alone and SCIT as an adjunctive treatment in children with moderate-to-severe AD, and assess the long-term clinical and immunological outcomes of this combination approach.
Methods: In this real-world study, patients with moderate-to-severe AD, who had IgE-mediated sensitization to house dust mites with varying degrees of respiratory symptoms, were divided into two treatment groups: Dupilumab + SCIT (n = 22) and dupilumab alone (n = 24).
