BACKGROUND: Oral immunotherapy to peanut is effective in desensitizing patients but has significant side effects including anaphylaxis and gastro-intestinal symptoms. In most protocols peanut is administered in a vehicle food. OBJECTIVE: In an exclusively adolescent population, we tested a new approach using sealed capsules of peanut (Gastro-Intestinal Delivery Oral Immunotherapy or GIDOIT) in order to bypass the upper gastro-intestinal tract. The primary aim was to assess the efficacy of the oral build-up phase of GIDOIT and the secondary aim to analyse its safety...

REVIEW
Amy M Scurlock
Development of active therapies for IgE-mediated food allergy is a critical action step toward alleviating the adverse medical, psychosocial, and economic burdens on affected patients and families. Significant progress has been observed specifically in the application of single-allergen oral and sublingual immunotherapy for treatment of IgE-mediated food allergy, with emphasis on milk, egg, and peanut as the primary allergens. Oral immunotherapy (OIT) has demonstrated efficacy in promoting immunomodulatory effects that lead to the clinical outcome of desensitization, defined as reduced reactivity while on active OIT, in the majority of treated individuals; however, achievement of sustained unresponsiveness following cessation of therapy has been observed in a smaller subset of treated subjects...

Model systems for oral cancer research have progressed from tumor epithelial cell cultures to in vivo systems that mimic oral cancer genetics, pathological characteristics, and tumor-stroma interactions of oral cancer patients. In the era of cancer immunotherapy, it is imperative to use model systems to test oral cancer prevention and therapeutic interventions in the presence of an immune system and to discover mechanisms of stromal contributions to oral cancer carcinogenesis. Here, we review in vivo mouse model systems commonly used for studying oral cancer and discuss the impact these models are having in advancing basic mechanisms, chemoprevention, and therapeutic intervention of oral cancer while highlighting recent discoveries concerning the role of immune cells in oral cancer...

PURPOSE OF REVIEW: In the last years, food allergy treatment is moving away from food avoidance to interventional treatments. We review here the recent developments on immunotherapy with food allergens. RECENT FINDINGS: Oral immunotherapy remains the best studied form of food immunotherapy. In 2017, further evidence has been added to its efficacy. Its mechanisms of action are under scrutiny. To reduce its side effects, studies have been dedicated to the simultaneous use of biologics, in particular omalizumab...

Inflammatory bowel disease (IBD) is a chronic disabling inflammatory process that affects young individuals, with growing incidence. The etiopathogenesis of IBD remains poorly understood. A combination of genetic and environmental factors triggers an inadequate immune response against the commensal intestinal flora in IBD patients. Thus, a better understanding of the immunological mechanisms involved in IBD pathogenesis is central to the development of new therapeutic options. Current pharmacological treatments used in clinical practice like thiopurines or anti-TNF are effective but can produce significant side effects and their efficacy may diminish over time...

The presence and benefit of a radiation therapy-associated immune reaction is of great interest as the overall interest in cancer immunotherapy expands. Radiation therapy (RT) pathology studies have rarely demonstrated a consistent immune or inflammatory response following conventional RT. More recent information, primarily associated with the "abscopal effect", suggests a subtle radiation-based systemic immune response may be more common and have more therapeutic potential than previously believed...

To improve current mucosal allergen immunotherapy Vibrio cholerae neuraminidase (NA) was evaluated as a novel epithelial targeting molecule for functionalization of allergen-loaded, poly(D,L-lactide-co-glycolide) (PLGA) microparticles (MPs) and compared to the previously described epithelial targeting lectins wheat germ agglutinin (WGA) and Aleuria aurantia lectin (AAL). All targeters revealed binding to Caco-2 cells, but only NA had high binding specificity to α-L fucose and monosialoganglioside-1. An increased transepithelial uptake was found for NA-MPs in a M-cell co-culture model...

A 25-year-old woman in her 37 weeks and 5 days pregnant presented with abnormal behavior and memory impairment following a high fever. Her manifestations were diagnosed as limbic encephalitis, and she delivered a baby by Cesarean section. In the operation, bilateral ovarian tumors were found and resected, though they were revealed as non-teratoma afterward. After operation, she became agitated, and started to present oral dyskinesia, intractable systemic myoclonus, central hypoventilation, and autonomic manifestations such as labile blood pressure, but her symptoms responded well to immunotherapy...

BACKGROUND: Oral immunotherapy (OIT) is a promising treatment for persons with allergy; however, it can also cause adverse allergic reactions. In this study, we investigated the efficacy of low-dose OIT for anaphylactic peanut allergy. METHODS: Twenty-four children (median age, 9.6 years) with anaphylaxis to peanuts were hospitalized for 5 days and then gradually fed increasing amounts of peanut powder up to 133 mg/day. One year later, they underwent an oral food challenge after 2 weeks of peanut avoidance...

OBJECTIVE: Introduction: Acne is one of the most common dermatological diseases. It may have a chronic course, leaving permanent marks, and in last years has been tending to have more and more severe clinical course with widespread skin lesions. According to recent studies, the development of acne is due to the combined effect of endogenous and exogenous factors, among which endocrine diseases (quite a significant aspect), disorders of metabolic processes, reduced systemic immunity and phagocytic ability of mononuclear phagocytes and granulocytes at various stages of phagocytosis of pyogenic cocci, which contributes to more severe clinical course, and frequent relapse of this diseases...

PURPOSE OF REVIEW: The prevalence of food allergy is increasing. More children are being diagnosed with food allergies, and it is taking longer to outgrow them, among those who develop tolerance. The aim of this review is to draw the profile of the persistent food allergic, so that prevention strategies can be developed and active treatment set up. RECENT FINDINGS: Many determinants are involved in food allergy prognosis: ethnicity and sex, type of food, innate immune system, eliciting dose, sensitization status and other biomarkers determination, gut microbiome composition, and the presence of comorbidities...

Background: Traditionally, study results have been presented as abstracts at major scientific meetings at the conclusion of the analysis. Recently, presentations of studies in progress and updates to previously presented data have been allowed at major meetings. The frequency and implications of a single study being presented multiple times, particularly in high profile oral presentations, have not been fully evaluated. Methods: To identify studies presented multiple times, abstracts from an approximately 1-year period from international conferences for three major societies devoted largely or in part to lung cancer research were assessed (ASCO 2015, World Lung 2015, ESMO 2015 and ASCO 2016)...

REVIEW
Meng Chen, Michael Welch, Susan Laubach
The rising prevalence of food allergy and specifically peanut allergy has had significant implications for affected patients, families, and society. The current standard of care remains strict avoidance and the use of emergency medications for accidental ingestions. There is recent evidence-based information to suggest that one approach to preventing peanut allergy lies in early introduction of peanut. This represents a paradigm shift from previous recommendations and has led to updated guidelines in the United States, Europe, and Australasia on the introduction of potentially allergenic foods in the infant diet...

BACKGROUND: Combined BRAF-MEK inhibitor therapy is the standard of care for BRAFV600 -mutant advanced melanoma. We investigated encorafenib, a BRAF inhibitor with unique target-binding properties, alone or in combination with the MEK inhibitor binimetinib, versus vemurafenib in patients with advanced BRAFV600 -mutant melanoma. METHODS: COLUMBUS was conducted as a two-part, randomised, open-label phase 3 study at 162 hospitals in 28 countries. Eligible patients were aged 18 years or older and had histologically confirmed locally advanced (American Joint Committee on Cancer [AJCC] stage IIIB, IIIC, or IV), unresectable or metastatic cutaneous melanoma, or unknown primary melanoma; a BRAFV600E or BRAFV600K mutation; an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1; and were treatment naive or had progressed on or after previous first-line immunotherapy...

Thrombomodulin (TM, also known as CD141), which functions as an anticoagulant, is widely expressed on cell surface of a variety of cell types, including human blood cells as well as certain immune cells. To determine whether TM could be a potential marker for OSCC diagnosis as well as a molecular target for OSCC therapy, we examined the expression of TM in an oral cancer tissue microarray with 153 oral cancer tissues. Further, we also analyzed the expression of TM on DCs of 36 OSCC patients and 36 healthy donors...

Case reports have described an association between oral food/aeroallergen immunotherapy with the development of eosinophilic oesophagitis (EoE). The underlying mechanism of this is poorly understood, as is the role that both food/aeroallergen sensitisation plays in the pathogenesis of EoE. Specific immunotherapy has a long-standing history of use in the management of moderate/severe seasonal allergic rhinitis (AR), caused by tree/grass pollens. Subcutaneous immunotherapy (SCIT) to grass pollen is less commonly used in children than sublingual immunotherapy (SLIT) or oral immunotherapy for practical reasons...
