Kimura disease (KD) is a rare benign chronic inflammatory condition that predominantly affects Asian males. It is characterized by subcutaneous tissue masses in the head and neck region, enlarged lymph nodes, increased blood eosinophilia, and elevated serum total IgE levels. In this report, we describe a rare case of KD in a young Vietnamese female. A 31-year-old Vietnamese woman presented to the hospital with 2 masses in the bilateral cheeks and 1 mass behind the left ear that persisted for 15 years, recurrent skin itching, elevated serum total IgE levels, and increased blood eosinophilia...

Atezolizumab, a humanized antiprogrammed death ligand 1 monoclonal immunoglobulin G1 antibody, is a targeted therapeutic drug known as an immune checkpoint inhibitor. It is currently used to treat various types of cancer, including unresectable hepatocellular carcinoma (HCC), nonsmall cell lung cancer, urothelial cancer, and breast cancer, and is becoming a therapeutic option in the forefront of oncology treatment. However, it may sometimes lead to undesirable adverse reactions owing to the activation of immune responses in various organs...

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a heterogeneous disease that affects a large proportion of the global population. The treatment of CRSwNP, especially eosinophilic CRSwNP (ECRSwNP), has always been of great obstacle. Our previous phase 2 trial showed that CM310, a monoclonal antibody that targets interleukin-4 receptor alpha, was both safe and effective in reducing the size of nasal polyps, improving symptom scores, and increasing the quality of life for those with severe ECRSwNP...

BACKGROUND: Respiratory allergies are one of the most common allergic diseases that affect Filipinos. Grass pollen accounts for the majority of the outdoor allergens triggering these respiratory allergies. Cross-reactivity among the Philippine grass pollen grains has not been extensively studied. OBJECTIVE: This study aims to investigate the cross-reactivity of our local grasses and identify the cross-reactive allergens. METHODS: Grass pollen grains were collected and processed into crude allergenic extracts...

Lipid transfer protein (LTP) has been documented as the dominant protein involved in food-induced anaphylaxis and food-dependent exercise-induced anaphylaxis (FDEIA) patients from Mediterranean European countries. To date, there is no report of FDEIA triggering by LTP in China. A 12-year-old Chinese boy experienced recurrent anaphylaxis during intense exercise for 3 months. Specific immunoglobulin E was performed using ImmunoCAP (Thermo Fisher Scientific, Sweden) and Euroline (EUROIMMUN, Germany). He was sensitized to several pollens, mainly mugwort (62 KUA/L), and was found to have detectable immunoglobulin E in multiple foods: cereal (wheat, barley, oat maize, rice, buckwheat, and common millet), fruits (peach, apple, grape, cherry, and orange), vegetables (lettuce, cabbage, broccoli, cauliflower, tomato, and celery), and legumes and nuts (soybean, peanut, and walnut)...

The advent of immune checkpoint inhibitors (ICIs) has revolutionized the treatment landscape for various malignancies by harnessing the body's immune system to target cancer cells. However, their widespread use has unveiled a spectrum of immune-related adverse events, highlighting a critical balance between antitumor immunity and autoimmunity. This review article delves into the molecular immunology of ICIs, mapping the journey from their therapeutic action to the unintended induction of immune-related adverse events...

BACKGROUND: The importance of IL-37 and downstream signal in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) demanding further investigation. OBJECTIVE: We sought to address the potential importance of the IL-37-IL-1R8 axis in regulating inflammatory response in patients with CRSwNP. METHODS: Nasal polyp (NP) tissues and control sinonasal tissues were obtained from adult CRSwNP, chronic rhinosinusitis without nasal polyps patients and healthy control subjects...

BACKGROUND: Respiratory allergy significantly impacts children's health and quality of life, with inhaled allergens serving as prevalent triggers for respiratory symptoms. Aeroallergen sensitization, confirmed through the skin prick test (SPT), naturally evolves over time and is influenced by environmental factors specific to each region. OBJECTIVE: This study aimed to review the updated 6-year trend of aeroallergen sensitization among children with asthma and allergic rhinitis in Southern Thailand...

BACKGROUND: Histones have been associated with human diseases. However, the implication of extranuclear histone proteins and their potential mechanism in the pathophysiology of chronic rhinosinusitis (CRS) have not been thoroughly investigated. This study was designed to evaluate the role of histones in patients with CRS by comparing histone expression between patients and controls. METHODS: Nasal polyp (NP) tissues were obtained, and their comprehensive gene expression profiles were investigated by microarray analysis...

Chemoimmunotherapy is an effective therapy for an individual with nonsmall-cell lung cancer (NSCLC) without anaplastic lymphoma kinase or epidermal growth factor receptor mutations. However, it can also be related to adverse cutaneous reactions such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) with high morbidities and mortality rates. We present a case of a 65-year-old male with NSCLC who underwent first-line chemotherapy with paclitaxel, carboplatin, and pembrolizumab, which was later followed by a second cycle of the same therapies...

BACKGROUND: The diagnosis of allergic rhinitis (AR) primarily relies on symptoms and laboratory examinations. Due to limitations in outpatient settings, certain tests such as nasal provocation tests and nasal secretion smear examinations are not routinely conducted. Although there are clear diagnostic criteria, an accurate diagnosis still requires the expertise of an experienced doctor, considering the patient's medical history and conducting examinations. However, differences in physician knowledge and limitations of examination methods can result in variations in diagnosis...

Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome belong to a family of severe cutaneous adverse reactions that can be life-threatening and carry a risk of significant morbidity and potential mortality in the event of re-exposure. Lifelong avoidance of the culprit agent is mandated, which can lead to the exclusion of multiple medications if the trigger is unclear. This can result in adverse health outcomes analogous to that of a penicillin allergy label. We present a case in which the patient would progress to fatal myeloma in the absence of treatment, however, multiple medications were administered prior to the occurrence of TEN following previous chemotherapy...

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a chronic inflammatory condition of the nasal and paranasal tissues, characterized by the presence of bilateral nasal polyps. An expert panel of specialists from the Asian-Pacific region and Russia was convened to develop regional guidance on the management of CRSwNP through a consensus approach. The present article presents the chief observations and recommendations from this panel to provide guidance for clinicians in these areas. Etiology and pathogenetic mechanisms in CRSwNP are heterogeneous and complex...

BACKGROUND: The cesarean section (CS) mode of delivery can influence the prevalence of bronchial asthma (BA), allergic rhinitis (AR), or atopic dermatitis (AD) by promoting modifications in the infantile microbiome. OBJECTIVE: To analyze the prevalence of asthma in children who were born through CS and attended childcare centers. METHODS: The data were obtained through an online survey that was answered anonymously by one of the parents; the survey inquired about the route of delivery of the child and the prevalence of BA, AR, and AD...

BACKGROUND: The diagnosis of allergic rhinitis is mainly based on the typical medical history, clinical manifestations, and corresponding allergen test results of the patients. However, there are often clinical inconsistencies among the 3. OBJECTIVE: To study the clinical characteristics of patients with allergic rhinitis from both subjective and objective aspects to determine the correlations between the quantitative assessment outcomes of subjective and objective indicators...

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) has a complex pathogenesis and is difficult to treat, which brings a huge economic burden to society. Despite all the progress in the treatment of CRSwNP, some patients with CRSwNP still experience recurrence. Therefore, there is an urgent need to develop novel drugs and treatments for CRSwNP. Thymic stromal lymphopoietin (TSLP) is produced by epithelial cells and mediates type 2 and nontype 2 inflammation through various downstream cellular immune and inflammatory pathways...

BACKGROUND: In the Americas there are few studies that have evaluated the frequency of allergic sensitization to Platanus occidentalis or sycamore pollen in adult patients with allergic rhinitis (AR). OBJECTIVE: To determine the prevalence of allergic sensitization to P. occidentalis and to identify factors associated with its presentation. METHODS: A cross-sectional study was carried out in 3 centers distributed in the northwest, west, and southeast of Mexico...
