Immune checkpoint inhibitors (ICI) represent new anticancer agents and have been used worldwide. However, ICI can potentially induce life-threatening severe cutaneous adverse reaction (SCAR), such as Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), hindering continuous ICI therapy. We examine 6 cohorts including 25 ICI-induced SJS/TEN patients and conduct single-cell RNA sequencing (scRNA-seq) analysis, which shows overexpression of macrophage-derived CXCL10 that recruits CXCR3 cytotoxic T lymphocytes (CTL) in blister cells from ICI-SJS/TEN skin lesions.

Background & objectives Spirometric glycopyrronium responsiveness, a new advent, needs to be examined at in terms of degree and frequency in different obstructive-airway diseases diagnosed in real world practise. Methods Serial and willing symptomatic affected individuals of suspected airway disease underwent a pragmatic post-consultation spirometry-protocol on the same day with salbutamol followed by glycopyrronium bromide. The diagnosis of asthma (FEV1-reversibility ≥ 200 ml + 12%), chronic obstructive pulmonary disease (COPD) (FEV1/FVC<0.

Objective: Asthma is a prevalent status attributing to lower respiratory tract chronic inflammation. Azithromycin (AZM) is known to be effective against asthma. Thus, this study delved into the mechanism of AZM repressing airway remodeling (AR) via the SAPK/JNK pathway in asthma.

Background/aim: We aimed to investigate the relationship between serum antidrug antibodies (ADAbs), systemic hypersensitivity, or local injection site reactions to tumor necrosis factor (anti-TNF) drugs and to detect the role of skin tests in the diagnosis of hypersensitivity reactions (HSRs) against anti-TNFs.
Materials And Methods: Sixty-nine ankylosing spondylitis (AS) and 46 rheumatoid arthritis (RA) patients taking infliximab (IFX), adalimumab (ADA), and etanercept (ETN) were enrolled. The demographical data, erythrocyte sedimentation rate (ESR), and c-reactive protein (CRP) levels of the patients were determined, and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) assessment for AS patients and DAS28 (disease activity score) for RA patients were assessed.
Clinicopathological features for the prediction of immunosuppressive treatment responses in sarcoidosis-related kidney involvement: a single-center retrospective study.

Division of Nephrology, Department of Internal Medicine, Faculty of Medicine, İstanbul University, İstanbul, Turkiye.
Background/aim: Sarcoidosis is a multisystem disorder that affects many organs, including the kidneys. This single-center retrospective study investigated the clinical, pathological, and laboratory findings of patients with kidney sarcoidosis who were treated with immunosuppressives.
Materials And Methods: Twenty-three patients with biopsy-confirmed kidney sarcoidosis were included.
