BACKGROUND: Egg oral immunotherapy is effective but time consuming. OBJECTIVE: To assess the efficacy and safety of egg rush oral immunotherapy (ROIT) with a targeted dose equivalent to a raw egg white. METHODS: Thirty-three persistent egg allergic children confirmed by double-blind, placebo-controlled food challenge (DBPCFC) were randomized to receive egg ROIT immediately after randomization (ROIT1 group), or to continue an egg avoidance diet for 5 months after randomization (control group [CG])...

Sublingual immunotherapy (SLIT) relies on high doses of allergens to treat patients with type I allergies. Although SLIT is commonly performed without any adjuvant or delivery system, allergen(s) could be further formulated with allergen-presentation platforms to better target oral dendritic cells eliciting regulatory immune responses. Improving the availability of allergens to the immune system should enhance SLIT efficacy, while allowing to decrease allergen dosing. Herein, we present an overview of adjuvants and vector systems that have been, or could be, considered as candidate allergen-presentation platforms for the sublingual route...

BACKGROUND: The European Academy of Allergy and Clinical Immunology (EAACI) is developing Guidelines for Allergen Immunotherapy (AIT) for IgE-mediated Food Allergy. To inform the development of clinical recommendations, we sought to critically assess evidence on the effectiveness, safety and cost-effectiveness of AIT in the management of food allergy. METHODS: We undertook a systematic review and meta-analysis that involved searching nine international electronic databases for randomized controlled trials (RCTs) and non-randomized studies (NRS)...

BACKGROUND: The minimal dose for oral immunotherapy (OIT) tolerance is unknown. We investigated the efficacy and safety of low-dose OIT with 1/32 of the volume of a whole egg. METHODS: Thirty-three children (aged ≥5 years) with egg allergies confirmed by oral food challenge against 1/32 of a heated whole egg (194 mg of egg protein) were enrolled. The OIT group ingested a scrambled egg once a day. The volume was gradually increased up to a maximum of 1/32 of a heated whole egg...

Immunotherapy for peanut allergy has been an exploding topic of study within the last few years. Sublingual, epicutaneous, and oral immunotherapy are being investigated and show promise in the treatment of peanut allergy. Oral immunotherapy has shown the most clinical benefit; however, sublingual and epicutaneous immunotherapy appear to have the most favorable safety profiles. Most studies to date suggest that only a minority of subjects achieve sustained unresponsiveness to peanut after discontinuation of immunotherapy...

BACKGROUND: Eosinophilic esophagitis (EoE) is an allergic inflammatory disease that is triggered by food allergens and characterized by progressive esophageal dysfunction. Recently, EoE has been identified in patients who underwent oral immunotherapy (OIT) for IgE-mediated food allergy, suggesting an association. OBJECTIVE: We sought to ascertain whether significant associations exist between IgE-mediated food allergies and EoE. METHODS: Using the analysis of electronic medical record data and manual chart review, we examined our subspecialty care network of 35,528 children and adolescents to identify and characterize patients with IgE-mediated and EoE food allergy...

Adult T cell leukemia/lymphoma (ATL), a CD4(+) T cell malignancy with a poor prognosis, is caused by human T cell leukemia virus type 1 (HTLV-1) infection. High proviral load (PVL) is a risk factor for the progression to ATL. We previously reported that some asymptomatic carriers had severely reduced functions of CTLs against HTLV-1 Tax, the major target Ag. Furthermore, the CTL responses tended to be inversely correlated with PVL, suggesting that weak HTLV-1-specific CTL responses may be involved in the elevation of PVL...

Food allergy develops as a consequence of a failure in oral tolerance, which is a default immune response by the gut-associated lymphoid tissues to ingested antigens that is modified by the gut microbiota. Food allergy is classified on the basis of the involvement of IgE antibodies in allergic pathophysiology, either as classic IgE, mixed pathophysiology or non-IgE-mediated food allergy. Gastrointestinal manifestations of food allergy include emesis, nausea, diarrhoea, abdominal pain, dysphagia, food impaction, protein-losing enteropathy and failure to thrive...

Epacadostat (EPA, INCB024360) is a selective inhibitor of the enzyme indoleamine 2,3-dioxygenase 1 (IDO1) and is being developed as an orally active immunotherapy to treat advanced malignancies. In the first clinical study investigating the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of EPA in oncology patients, increasing doses of EPA ranging from 50 mg once daily to 700 mg twice daily were administered as a monotherapy to 52 subjects with advanced solid tumors. The EPA plasma concentration-time profiles were adequately described by a population PK model comprised of the first-order kinetics of oral absorption with 2-compartment distribution and constant clearance from the central compartment...

Allergen immunotherapy (AIT) has been in use since more than one century, when Leonard Noon experimentally proved its efficacy in hayfever (Noon, in Lancet 1:1572-3, 1911). Since then, AIT was administered only as subcutaneous injections (SCIT) until the sublingual route (SLIT) was proposed in 1986. The use of SLIT was proposed following several surveys from the USA and UK that repeatedly reported fatalities due to SCIT (Lockey et al. in J Allergy Clin Immunol 75(1): 166, 1985; Lockey et al. in J Allergy Clin Immunol 660-77, 1985; Committee on the safety of medicines...

CTLA-4, PD-1, and PD-L1 monoclonal antibodies, commonly known as immune checkpoint inhibitors, are used for the treatment of various malignancies. The mechanism of action involves the inhibition of negative regulators of immune activation, which results in many patients developing immune-related adverse events (irAEs) including endocrinopathies, pneumonitis, colitis, hepatitis and dermatologic events. Dermatologic irAEs include maculopapular rash, pruritus, vitiligo, blistering disorders, mucocutaneous lichenoid eruptions, rosacea, and exacerbation of psoriasis...

The present paper addresses severe asthma which is limited to 5-10% of the overall population of asthmatics. However, it accounts for 50% or more of socials costs of the disease, as it is responsible for hospitalizations and Emergency Department accesses as well as expensive treatments. The recent identification of different endotypes of asthma, based on the inflammatory pattern, has led to the development of tailored treatments that target different inflammatory mediators. These are major achievements in the perspective of Precision Medicine: a leading approach to the modern treatment strategy...

Oral vaccines have become a recent focus because of their potential significance in disease prevention and therapy. In the development of oral vaccine-based therapeutics, synthetic materials with tailorable structures and versatile functions can act as antigen conveyers with adjuvant effects, reduce the time cost for vaccine optimization, and provide high security and enhanced immunity. This review presents an overview of the current status of tailoring synthetic adjuvants for oral vaccination, modification strategies for producing effectors with specific structures and functions, enhancement of immune-associated efficiencies, including the barrier-crossing capability to protect antigens in the gastrointestinal tract, coordination of the antigens penetrating mucosa and cell barriers, targeting of concentrated antigens to immune-associated cells, and direct stimulation of immune cells...

BACKGROUND: Oral immunotherapy (OIT) for food allergy is gaining interest due to the favorable clinical results reported with cow's milk, hen egg and peanut. The safety of the procedure remains a critical aspect that can limit the introduction of OIT in clinical practice. OBJECTIVE: We described herein, in detail, the occurrence and characteristics of adverse events (AE) with OIT in children who participated in controlled trials at our unit. METHODS: The clinical records of 68 children who received active treatment (40 for cow's milk and 28 for hen egg) were carefully reviewed...

Oral cavity mucosal melanomas (OCMM) represent only 3% of all malignant melanomas. Surgery is the mainstay of treatments and it is often followed by adjuvant radiotherapy. The role of adjuvant immunotherapy and/or chemotherapy is still debated and to date neither treatment is routinely used. From January 1990 to January 2010, we have collected from our database data of 20 patients with a histologically proven diagnosis of OCMM. Upfront surgery, followed by adjuvant radiotherapy was performed in 16/20 (80%) patients...

Blockade of the programmed-death 1 receptor (PD-1)/programmed-death ligand (PD-L1) pathway efficiently reduces tumour growth and improves survival. Durable tumour regression with blockade of the PD-1/PD-L1 checkpoint has been demonstrated in recent clinical studies. Oral squamous cell carcinoma (OSCC) is highly immunosuppressive, and PD-L1 expression has been proposed as a potential mechanism responsible for this phenotype. Despite the fact that anti-PD-1 treatment can produce durable responses, such therapy appears to benefit only a subset of patients...

Since the discovery of Clostridium difficile infection (CDI) in the 1970s, there has been an increase in the incidence, severity, and recurrence rate of the disease. We reviewed the recent CDI literature in PubMed published before February 28, 2016 that focused on advances in therapy. Despite a large number of studies describing methods for diagnosing the disease, there is currently no definitive test that identifies this infection with certainty, which complicates therapy. Recommended therapy for CDI includes oral metronidazole for mild cases and oral vancomycin or fidaxomicin for moderate to severe cases, each given for 10 to 14 days...

BACKGROUND: Egg allergy is one of the most common food allergies in young child. While oral immunotherapy (OIT) is not routinely recommended in current guidelines, it has been considered as a potential alternative treatment strategy. Studies on OIT for food allergies have been explored; however, no studies with control group have been reported in Japan. METHODS: The first oral food challenge test (OFC) was performed on participants before treatment to ensure the diagnosis and evaluate the threshold dose for egg by the way of double-blind, placebo-controlled food challenge (DBPCFC)...
