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)...

The advent of novel small-molecule inhibitors has transformed the treatment approaches for patients with chronic lymphocytic leukemia (CLL). These therapies are becoming increasingly used in patients with relapsed disease, patients with 17p deletion, and, as of recently, also in the frontline setting for previously untreated patients with CLL. Moreover, many of these are oral therapies that are significantly less myelosuppressive than chemoimmunotherapy. However, these agents have their own set of unique toxicities with which providers must gain familiarity...

Oral immunotherapy-induced gastrointestinal and eosinophilic responses (OITIGER) is an adverse response to OIT in ∼8% of patients and is typically reversible by decreasing dosage administration. The peripheral blood eosinophil count serves as a biomarker marker for susceptibility and the medical course.

BACKGROUND: Immunotherapy targeting the checkpoint PD1 (programmed cell death protein 1) or PDL1 (programmed death ligand 1) has led to advances in the treatment of melanoma and non-small cell lung cancer (NSCLC). The use of such therapies has also been introduced into the treatment of other malignancies, including head and neck cancer. The combined effects of checkpoint inhibitors and anti-PD1(L1) antibodies and radiation therapy have not yet been sufficiently investigated. CASE PRESENTATION: We report a case of locally relapsed non-resectable oral cavity squamous cell carcinoma, with excellent local control after pembrolizumab (MK3475) followed by radiotherapy...

Mycobacterium W (Mw) vaccine has been found to be effective in the treatment of leprosy and warts. Despite increasing use of Mw immunotherapy, data on its safety is limited. We report a series of eight patients who developed persisting injection site granulomatous reaction following Mw immunotherapy and were successfully treated with minocycline. Eight patients with persistent nodular swelling at the site of Mw injections were identified. Seven of them had received Mw immunotherapy for cutaneous warts and one for verrucous epidermal nevus...

BACKGROUND: Insect bite hypersensitivity is an IgE-mediated dermatitis of horses initiated by bites of midges of the genus Culicoides. Culicoides spp. are not indigenous to Iceland and the prevalence of insect bite hypersensitivity is much higher in horses born in Iceland and exported as compared to Icelandic horses born in a Culicoides rich environment. Immunotherapy is therefore needed. OBJECTIVES: The aim of the study was to express an allergen from Culicoides in barley grain and investigate whether an immune response could be obtained in healthy Icelandic horses by oral treatment with transgenic barley expressing the allergen...

BACKGROUND AND PURPOSE: Acetylcholinesterase inhibitors (AChEIs) are widely used to treat myasthenia gravis (MG). Although AChEIs are usually tolerated well, some MG patients suffer from side effects. Furthermore, a small proportion of MG patients show cholinergic hypersensitivity and cannot tolerate AChEIs. Because repetitive compound muscle action potentials (R-CMAPs) are an electrophysiologic feature of cholinergic neuromuscular hyperactivity, we investigated the clinical characteristics of MG patients with R-CMAPs to identify their clinical usefulness in therapeutic decision-making...

BACKGROUND: The systemic immune system plays a role in inflammation and fibrogenesis associated with non-alcoholic steatohepatitis (NASH) and has become a potential target for drug development. In particular, the gut immune system has been suggested as a means for generating signals that can target the systemic immune system. AIM: To describe seven novel methods being developed for the treatment of NASH that target the gut immune system for alleviation of the systemic inflammatory response, including oral administration of fatty-liver-derived proteins, anti-CD3 antibodies, tumour necrosis factor fusion protein, anti-lipopolysaccharide antibodies, glucosylceramide, delayed-release mercaptopurine, and soy-derived extracts...

A 87-year-old female presented with subacute progression of cognitive decline. Fluid-attenuated inversion recovery images of brain MRI showed multifocal high-intensity lesions. Thoracic CT image revealed the presence of thymoma, and serum autoantibody screening showed positivity for anti-gamma aminobutyric acid (GABA)A receptor antibody. Histopathological analysis confirmed type B3 thymoma after thymectomy. The patient received both plasmapheresis and intravenous methylprednisolone therapy, and showed remarkable amelioration of clinical symptoms and MRI abnormal high intensity...

INTRODUCTION: Vaccination with dendritic cells (DCs) has generally not fulfilled its promise in cancer immunotherapy due to ineffective translation of immune responses into clinical responses. A proposed reason for this is intrinsic immune regulatory mechanisms, such as regulatory T cells (Tregs). A metronomic regimen of cyclophosphamide (mCy) has been shown to selectively deplete Tregs. To test this in a clinical setting, we conducted a phase I trial to evaluate the feasibility and safety of vaccination with DCs transfected with mRNA in combination with mCy in patients with metastatic malignant melanoma (MM)...

Docetaxel based chemotherapy showed survival benefit and emerged as the mainstay of treatment for castration resistant prostate cancer (CRPC) in 2004. However, therapeutic options have expanded rapidly since 2011. The spectrum of new agents is broad and includes drugs that target the androgen axis (enzalutamide, abiraterone), immunotherapy (sipuleucel-T), bone seeking radionuclides (radium-223), and second line chemotherapy (cabazitaxel). In addition, new agents have been developed to reduce skeletal related events (denosumab)...

PURPOSE OF REVIEW: The rise in the prevalence of food allergy over the past decades has focused attention of factors that may impact disease development, most notably the gut microbiota. The gut microbial communities play a crucial role in promoting oral tolerance. Their alteration by such factors as Cesarean section delivery, diet and antibiotics may influence disease development. This review highlights recent progress in our understanding of the role of the gut microbiota in the development of food allergy...
