Pathophysiology of Congenital High Production of IgE and Its Consequences: A Narrative Review Uncovering a Neglected Setting of Disorders.

Elevated serum IgE levels serve as a critical marker for uncovering hidden immunological disorders, particularly inborn errors of immunity (IEIs), which are often misdiagnosed as common allergic conditions. IgE, while typically associated with allergic diseases, plays a significant role in immune defense, especially against parasitic infections. However, extremely high levels of IgE can indicate more severe conditions, such as Hyper-IgE syndromes (HIES) and disorders with similar features, including Omenn syndrome, Wiskott-Aldrich syndrome, and IPEX syndrome.

Update on the Role of β2AR and TRPV1 in Respiratory Diseases.

Respiratory diseases (RDs) constitute a common public health problem both in industrialized and developing countries. The comprehension of the pathophysiological mechanisms underlying these conditions and the development of new therapeutic strategies are critical for improving the quality of life of affected patients. β2-adrenergic receptor (β2AR) and transient receptor potential vanilloid 1 (TRPV1) are both involved in physiological responses in the airways.

Baked Egg Oral Immunotherapy: Current State in Pediatric Age.

Hen's egg allergy is one of the most common food allergies in the Western world, with an increase in recent years. It affects about 9.5% of the pediatric population, and the onset most often occurs before the first year of life.

Omalizumab reduces anaphylactic reactions and allows food introduction in food-allergic in children with severe asthma: An observational study.

Background: In Europe, Omalizumab (anti-IgE) is indicated for the treatment of moderate to severe asthma, but not for IgE-mediated food allergy (FA).

Objective: We assessed the impact of Omalizumab on efficacy, safety, and quality of life (FA-QoL) in patients with moderate to severe asthma and who have a history of anaphylaxis to peanut, tree nuts, fish, egg, milk, and/or wheat.

Methods: Food-allergic children (6-18 years) with moderate to severe asthma underwent oral food challenges (OFCs) to establish the threshold of reaction to the culprit food(s) at baseline (T0) and at 4-month intervals (T1, T2, and T3) during their first year of treatment with Omalizumab.

Immune Response to Respiratory Viral Infections.

The respiratory system is constantly exposed to viral infections that are responsible for mild to severe diseases. In this narrative review, we focalized the attention on (RSV), influenza virus, and (SARS-CoV-2) infections, responsible for high morbidity and mortality in the last decades. We reviewed the human innate and adaptive immune responses in the airways following infection, focusing on a particular population: newborns and pregnant women.

Device-Related Skin Reactions Increase Emotional Burden in Youths With Type 1 Diabetes and Their Parents.

Background: Skin reactions due to technological devices pose a significant concern in the management of type 1 diabetes (T1D). This multicentric, comparative cross-sectional study aimed to assess the psychological impact of device-related skin issues on youths with T1D and their parents.

Methods: Participants with skin reactions were matched in a 1:1 ratio with a control group.

The Prevention of House Dust Mite Allergies in Pediatric Asthma.

This review provides a concise overview of preventive measures against dust mite allergies in pediatric populations, emphasizing the need for a comprehensive and evolving approach. Dust mites, ubiquitous microscopic arachnids, pose a significant threat to children's health, triggering allergies and asthma. Traditional preventive strategies such as regular cleaning, mattress covers, and humidity control are essential but warrant refinement.

Early Assessment of Efficacy and Safety of Biologics in Pediatric Allergic Diseases: Preliminary Results from a Prospective Real-World Study.

Background: Despite the increasing interest in biologics for the management of allergic diseases, sparse real-world data are still available in the pediatric population. This study aimed to evaluate the early real-life efficacy and safety of omalizumab for patients with moderate-to-severe asthma and chronic spontaneous urticaria (CSU), and Dupilumab for patients with moderate-to-severe atopic dermatitis (AD).

Methods: A prospective study enrolling children aged 6-18 years was designed to assess the efficacy and safety of biologic drugs at 16 weeks of treatment (T1).

Vitulia questionnaire: a new instrument to evaluate quality of life in children aged 4-7 years with food allergy.

Food allergy (FA) negatively affects health-related quality of life (HR-QoL) of children and caregivers. To date, no questionnaire self-compiling assessing the HR-QoL in pre-school children with FA is available. The aim of this study is to develop and validate a self-administered, rapid and easy questionnaire to evaluate the HR-QoL in children ≥ 7 years with IgE-mediated FA.

Impact of the Allergic Therapeutic Adherence in Children with Allergic Rhinitis and ADHD: A Pilot Study.

Background: Allergic rhinitis (AR) is the most common chronic allergic disease in children. Several studies have shown an association between attention deficit hyperactivity disorder (ADHD) and allergies, especially AR. Patients with ADHD usually have poor therapeutic adherence, and untreated AR symptoms may worsen the quality of life of patients.

Long-Term Safety of Omalizumab in Children with Asthma and/or Chronic Spontaneous Urticaria: A 4-Year Prospective Study in Real Life.

Insufficient data are available on the long-term "real-life" safety profile of omalizumab in children. This study evaluated the long-term safety of omalizumab in a pediatric cohort with severe asthma or chronic spontaneous urticaria (CSU). A monocentric, prospective study evaluated the long-term safety of omalizumab in patients aged 6-18 years.

Hemophagocytic lymphohistiocytosis following gene replacement therapy in a child with type 1 spinal muscular atrophy.

What Is Known And Objective: Onasemnogene abeparvovec (OA) is the first gene replacement therapy for the treatment of paediatric patients with bi-allelic mutations in the SMN1 gene. Efficacy and safety of OA have been assessed in several studies with promising results, despite rare side effects have been described.

Case Summary: A 3-year-old child with spinal muscular atrophy was treated with OA and subsequently developed fever, widespread erythematous skin lesions and hepatosplenomegaly.

An overview of the current state of food desensitization.

Purpose Of Review: To highlight the current evidence on food desensitization in children with food allergy.

Technologies for Type 1 Diabetes and Contact Dermatitis: Therapeutic Tools and Clinical Outcomes in a Cohort of Pediatric Patients.

The increasing use of technological devices for the management of diabetes is related to the prolonged exposure of patients' skin to chemical and mechanical agents and, consequently, to the increased risk of developing dermatological complications. Among these, contact dermatitis is the most insidious skin disorder. Despite the magnitude of the issue, no universally accepted recommendations on the management of this common complication are currently available.

Negative effect of lockdown on juvenile idiopathic arthritis patients.

Introduction: The aim of this study is to evaluate a possible negative action of lockdown, during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, in the follow-up of juvenile idiopathic arthritis (JIA) patients.

Methods: We compared the number of JIA reactivations in the period March-July 2020 to the same months of 2018 and 2019.

Cardiotoxicity from anthracycline and cardioprotection in paediatric cancer patients.

Notwithstanding the steady progress in survival rates of children and adolescents suffering from cancer, the benefits associated with chemotherapy do not come without risks involving multiple organs and systems, including the cardiovascular apparatus. Anthracyclines-often administered in combination with radiation therapy and/or surgery-are the most used chemotherapeutic compounds in order to treat tumours and blood malignancies even in paediatric age. Being an important side-effect of anthracyclines, carduitoxicity may limit their efficacy during the treatment and induce long-term sequelae, observed even many years after therapy completion.

Pathophysiology of cardiotoxicity from target therapy and angiogenesis inhibitors.

The progress in cancer therapy and the increase in number of long-term survivors reveal the issue of cardiovascular side-effects of anticancer drugs. Cardiotoxicity has become a significant problem, and the risks of adverse cardiac events induced by systemic drugs need to be seriously considered. Potential cardiovascular toxicities linked to anticancer agents include arrhythmias, myocardial ischemia and infarction, hypertension, thromboembolism, left ventricular dysfunction, and heart failure.
