Cyclosporine successfully treats steroid-resistant checkpoint inhibitor-related pneumonitis: a case report.

Background: Immune checkpoint inhibitor-related pneumonitis (CIP) stands out as a particularly severe adverse event caused by immune checkpoint inhibitors, with a substantial real-world incidence ranging from 13 to 19%. While systemic corticosteroids represent the standard treatment for CIP, therapeutic options become limited in cases where patients do not respond to corticosteroid therapy. Such patients are classified as having steroid-resistant CIP, often associated with a poor prognosis.

The prognostic impact of severe grade immune checkpoint inhibitor related pneumonitis in non-small cell lung cancer patients.

Objective: To compare the prognostic differences between non-small cell lung cancer (NSCLC) patients with mild and severe checkpoint inhibitor-associated pneumonitis (CIP), and explore the causes of death and prognostic risk factors in NSCLC patients with severe CIP.

Methods: A retrospective study of a cohort of 116 patients with unresectable stage III or IV NSCLC with any grade CIP from April 2016 to August 2022 were conducted. To analyze the clinical characteristics of patients with different CIP grades, patients were divided into mild CIP group (grade 1-2, n=49) and severe CIP group (grade 3-5, n=67) according to the grade of CIP.

Rapid removal of Rhodamine B by phosphoric acid-modified activated carbon derived from rape straw.

A series of activated carbon was obtained from rape straw by chemical modification with phosphoric acid (HPO). The activated carbon was characterized and the adsorption capacity for Rhodamine B (RhB) from water was analysed. The SEM images showed that PRC-40 is a porous material and the BET analysis revealed a high surface area of 1720 m/g with the coexistence of micropores and mesopores.

Identification of Chinese baijiu from the same brand based on a graphene quantum dots fluorescence sensing array.

The identification of Chinese baijiu is crucial to regulating the international market and maintaining legitimate rights, as the popularity, influence and awareness of baijiu are growing. A graphene quantum dot (GQD) based fluorescence sensor array is designed in this paper. Upon using only GQDs as a single sensing element, combining three different solvents improves the sensing array's detection sensitivity while simplifying material preparation and experimental detection.

Organic acid-induced triple fluorescent emission carbon quantum dots identification of distilled liquor.

An acid-sensitive carbon dot fluorescence sensing array was investigated for the differentiated recognition of distilled spirits. Due to the electrostatic interactions between CDs and organic acids, organic acids affect the protonation and fluorescence properties of CDs, which in turn modify the CDs triple fluorescence emission. The regular linear variation of the fluorescence sensor was found under acidic conditions (3.

Successful management of Epstein‑Barr virus‑associated severe checkpoint inhibitor‑related pneumonitis: A case report.

A novel current treatment, immunotherapy, is normally effective for pulmonary lymphoepithelial carcinoma (pLELC). However, it is frequently accompanied by responses such as immune checkpoint inhibitor-associated pneumonitis (CIP), a rare immune adverse reaction that may be fatal in severe cases. pLELC is known to be linked to Epstein-Barr virus (EBV), while associations between EBV and CIP in clinical settings have rarely been reported.

A Risk-Scoring Model for Severe Checkpoint Inhibitor-Related Pneumonitis: A Case-Control Study.

Background And Objective: Checkpoint inhibitor-related pneumonitis (CIP) is one of the most common serious and fatal adverse events associated with immune checkpoint inhibitors (ICIs). The study sought to identify risk factors of all-grade and severe CIP and to construct a risk-scoring model specifically for severe CIP.

Methods: This observational, retrospective case-control study involved 666 lung cancer patients who received ICIs between April 2018 and March 2021.

Case report: Spontaneous remission in lung carcinoma with a late relapse after adjuvant immunotherapy: Exceptional tumor micro-environment.

Spontaneous remission (SR) of local recurrence after adjuvant immunotherapy has rarely been reported, and the underlying mechanism is poorly understood. Herein, we reported a patient with stage cT2aN2M0 squamous cell lung carcinoma who received neoadjuvant and adjuvant treatment with nivolumab plus chemotherapy. The patient experienced a late relapse in the subcarinal lymph node seven months after the last dosage of treatment but achieved SR in the next three months without additional antitumor therapy.

Comprehensive Analysis of the Immune Microenvironment in Checkpoint Inhibitor Pneumonitis.

Background: While immune checkpoint inhibitors (ICIs) are a beacon of hope for non-small cell lung cancer (NSCLC) patients, they can also cause adverse events, including checkpoint inhibitor pneumonitis (CIP). Research shows that the inflammatory immune microenvironment plays a vital role in the development of CIP. However, the role of the immune microenvironment (IME) in CIP is still unclear.

Identification of the Unique Clinical and Genetic Features of Chinese Lung Cancer Patients With Germline Mutations in a Large-Scale Retrospective Study.

Background: Epidemiological surveys have suggested that lung cancer has inherited susceptibility and shows familial aggregation. However, the distribution and prevalence of epidermal growth factor receptor () germline variants and their roles in lung cancer genetic predisposition in Chinese population remain to be elucidated.

Methods: In this study, germline and somatic variants were retrospectively reviewed from the next-generation sequencing results of 31,906 patients with lung cancer.
