Background: Immune checkpoint inhibitors (ICIs) improve cancer survival but can induce immune-related adverse events (irAEs). Pre-existing autoantibodies, particularly antinuclear antibodies (ANAs), have been suggested as predictive biomarkers for irAE development. However, prior studies have yielded mixed results.

However, a risk assessment method for the disease has not been established. This was a prospective study that aimed to identify a blood biomarker to assess a risk of severe CIP.

The characteristic responses to ICI treatment include pseudoprogression (PP) and hyperprogressive disease (HPD), which require attention. Reports on PP of MPM are rare.

Treatment strategies for osimertinib-induced ILD are not well established. Cytotoxic anticancer drugs are considered first, although several cases of successful rechallenge with EGFR-TKIs have been reported.

Background: Oral food challenge (OFC) is the gold standard for diagnosing food allergies (FAs) but carries the risk of anaphylactic reaction. Stepwise OFC, starting with a low dose of allergen and progressing to medium and full doses, is effective in determining a tolerable dose. We retrospectively evaluated the results of a stepwise OFC for hen's egg (HE) to demonstrate its safety and efficacy.

Introduction: Cow's milk (CM) is one of the most common food allergens in Japan. The oral food challenge (OFC) of CM is important for the definite diagnosis of children with CM allergy, and it is recommended to be actively and safely performed in individuals with low CM-sIgE levels. This study aimed to investigate the safety of low-dose CM-OFC in individuals with low CM-sIgE levels and discuss the prognostic factors and appropriate approaches for assessing the starting doses of CM-OFC in these individuals.

Introduction: Stepwise oral food challenge (OFC) tests begin with low doses of allergens and progress to full doses. We previously reported the safety and efficacy of stepwise OFC for reintroducing hen eggs. In this study, we discuss its application for cow's milk (CM) allergy.

Introduction: During an oral food challenge (OFC), there is a risk of adverse reactions, including anaphylaxis. Therefore, the physician should carefully conduct the OFC. This study aimed to evaluate the OFC results in individuals with low levels of egg white (EW)- and ovomucoid (OVM)-specific immunoglobulin E (sIgE) and the safety of a hen's egg (HE) OFC in these individuals.

Patients And Methods: We conducted a multicentre, retrospective, cohort study of patients with advanced EGFR-mutated lung cancer who received EGFR-tyrosine kinase inhibitors (TKIs) between 2012 and 2019. The primary outcome was the incidence of HT.
Immune checkpoint inhibitors (ICIs), including nivolumab, have exhibited substantial benefits in the treatment of several types of cancers. However, treatment with ICIs is often accompanied by immune-related adverse events (irAEs), and a clear understanding of the precise indications and management of irAEs is important for harnessing the full potential of these agents. While skin- or gastrointestinal-associated irAEs have been relatively well studied, there are few reports regarding nivolumab-induced cholangitis.

We aimed to assess safety and efficacy of ciclosporin, an immunosuppressant targeting this pathway, for protection of patients with Kawasaki disease against coronary artery abnormalities.
Methods: We did a randomised, open-label, blinded endpoints trial involving 22 hospitals in Japan between May 29, 2014, and Dec 27, 2016.

Background: Japanese encephalitis (JE) is the leading cause of viral encephalitis with high mortality and morbidity in Asia. In Japan, however, the active recommendation of JE vaccine was retracted in 2005 because of the potential risk of acute disseminated encephalomyelitis. We aimed to determine the recent incidence of childhood-onset JE after the domestic change of vaccination policy in Japan, and to analyze the clinical features of affected children.

The first administration of ZOL is occasionally associated with development of acute-phase reaction (APR), which is due to activation of γδ T cells. ZOL-related APR was associated with better overall survival (OS) of patients with non-small cell lung cancer (NSCLC) in our previous retrospective study.

We investigated the inhibitory effects of RvE1 on osteoclastogenesis and bone resorption to clarify its therapeutic potential for rheumatoid arthritis (RA).
Methods: Receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast differentiation was assessed with tartrate-resistant acid phosphatase staining.
Nitrogen-containing bisphosphonates (N-BPs), which are usually used for the treatment of advanced cancer with bone metastasis, occasionally cause fever following the first administration. However, it is unclear as to how the development of fever following the first administration of N-BP is associated with clinical outcome. The aim of the present study was to determine the prognostic value of the development of fever following the first administration of N-BP in advanced non-small cell lung cancer patients with bone metastases.

We have shown that γ-tocotrienol inhibits human airway smooth muscle cell proliferation and migration induced by platelet-derived growth factor (PDGF)-BB by suppressing RhoA activation. In this study, we tested whether γ-tocotrienol modulates transforming growth factor (TGF) -β-induced induction of human airway smooth muscle (ASM) into a contractile phenotype and concomitant synthesis of extracellular matrix proteins.

Cancer cells acquire resistance to such therapies by repairing DNA DSBs. A major pathway for the repair of DNA DSBs is non-homologous end-joining (NHEJ), which requires DNA-dependent protein kinase (DNA-PK) activity.

We describe the cases of three infants between 4 and 9 months of age with disseminated bacillus Calmette-Guerin (BCG) infection who developed persistent fever, skin rash, and multiple chest nodules visible on computed tomography 22-34 days after BCG vaccination. These infants were healthy before inoculation, and their detailed immunological profiles, including T cell and neutrophil levels, were within normal range. Most reported BCG cases involve impaired immunity, such as children with chronic granulomatous disease, severe combined immunodeficiency, or human immunodeficiency virus infections.

Epidermal growth factor receptor (EGFR) gene mutation testing is essential for choosing appropriate treatment options in patients with advanced non-small cell lung cancer (NSCLC). However, a time delay occurs between histological diagnosis and molecular diagnosis in clinical situations. To minimize this delay, we developed a novel point-of-care test for EGFR mutations, based on a high-speed real-time polymerase chain reaction (PCR) system designated here as ultrarapid PCR combined with highly accurate bronchoscopic sampling.

Although cytotoxic chemotherapy is essential in epidermal growth factor receptor (EGFR)‑mutated non‑small cell lung cancer (NSCLC), it is unclear which regimen is most effective. We retrospectively compared the efficacy of standard platinum‑based chemotherapy with that of combination chemotherapy using vinorelbine (VNR) plus dihydropyrimidine dehydrogenase‑inhibitory fluoropyrimidine (DIF) in EGFR‑mutated lung adenocarcinomas, and we investigated a potential mechanism by which the combination chemotherapy of VNR + DIF was favorable in the treatment of EGFR‑mutated lung adenocarcinoma in vitro. In our retrospective analysis, the response rate and disease control rate afforded by the VNR + DIF treatment tended to be better than those by platinum‑based chemotherapy, and the progression‑free survival of the 24 VNR + DIF‑treated patients was significantly longer than that of the 15 platinum‑based chemotherapy patients.
