AI Article Synopsis

  • Researchers conducted whole genome sequencing on 66 cases of CNS toxicity induced by antimicrobial drugs and 833 controls to explore genetic predispositions.
  • The study primarily examined the role of seventeen efflux transporters at the blood-brain barrier and found no significant association, but identified uncommon genetic variants linked to CNS toxicity.
  • Three specific genes—LCP1, RETSAT, and SFMBT2—were associated with the toxicity, particularly variants in LCP1 that showed strong statistical significance.

Article Abstract

A genetic predisposition to central nervous system (CNS) toxicity induced by antimicrobial drugs (antibiotics, antivirals, antifungals, and antiparasitic drugs) has been suspected. Whole genome sequencing of 66 cases and 833 controls was performed to investigate whether antimicrobial drug-induced CNS toxicity was associated with genetic variation. The primary objective was to test whether antimicrobial-induced CNS toxicity was associated with seventeen efflux transporters at the blood-brain barrier. In this study, variants or structural elements in efflux transporters were not significantly associated with CNS toxicity. Secondary objectives were to test whether antimicrobial-induced CNS toxicity was associated with genes over the whole genome, with HLA, or with structural genetic variation. Uncommon variants in and close to three genes were significantly associated with CNS toxicity according to a sequence kernel association test combined with an optimal unified test (SKAT-O). These genes were LCP1 (q = 0.013), RETSAT (q = 0.013) and SFMBT2 (q = 0.035). Two variants were driving the LCP1 association: rs6561297 (p = 1.15x10-6, OR: 4.60 [95% CI: 2.51-8.46]) and the regulatory variant rs10492451 (p = 1.15x10-6, OR: 4.60 [95% CI: 2.51-8.46]). No common genetic variant, HLA-type or structural variation was associated with CNS toxicity. In conclusion, CNS toxicity due to antimicrobial drugs was associated with uncommon variants in LCP1, RETSAT and SFMBT2.

A 28-year-old woman was diagnosed with high-risk triple-expressor diffuse large B-cell lymphoma (DLBCL) (stage IV, IPI 4, CNS-IPI 5), with lymph node and extranodal involvement. The patient underwent first-line R-CHOP treatment, achieving a partial response with residual mediastinal uptake. A second-line platinum-based therapy with a transplant plan followed, resulting in stable disease; thus, she was considered refractory and started third-line therapy with CAR-T cells, receiving additional chemotherapy as bridging therapy.

BRAF inhibitor monotherapy in BRAFV600E-mutated pediatric low-grade glioma: a single center's experience.

Front Oncol

Department of Pediatrics, Children's Healthcare of Atlanta, Atlanta, GA, United States.

Background: Pediatric low-grade gliomas (pLGGs) have an overall survival of over 90%; however, patients harboring a BRAF alteration may have worse outcomes, particularly when treated with classic chemotherapy. Combined BRAF/MEK inhibition following incomplete resection demonstrated improved outcome in BRAF altered pLGG compared to combined carboplatin/vincristine chemotherapy and is now considered the standard FDA-approved treatment for this group of tumors. The aim herein was to investigate the efficacy and tolerability of single agent BRAF inhibitor treatment in BRAF altered pLGG.

Environmental endocrine disruptor chemicals (EDCs) have raised significant concerns due to their potential adverse effects on human health, particularly on the central nervous system (CNS). This study provides a comparative analysis of the effects of 17-alpha ethinyl estradiol (EE2) and diethyl phthalate (DEP) on neuronal cell proliferation and neurotoxicity. Using differentiated SH-SY5Y human neuronal cells, we evaluated cell viability, microRNA (miRNA) regulation, and RNA expression following exposure to subtoxic concentrations of EE2 and DEP.

Astrocytes play important roles in the central nervous system (CNS) during health and disease. Prior studies have shown that gut commensals derived indole derivatives as well as secondary bile acids modulate astrocyte function during the late stage of EAE (recovery phase). Here we show that administering vancomycin to mice starting during the early stage of EAE improved disease recovery, an effect that is mediated by the gut microbiota.

Programmed neurite degeneration in human central nervous system neurons driven by changes in NAD metabolism.

Cell Death Dis

Neurite degeneration (ND) precedes cell death in many neurodegenerative diseases. However, it remains unclear how this compartmentalized cell death process is orchestrated in the central nervous system (CNS). The establishment of a CNS axotomy model (using modified 3D LUHMES cultures) allowed us to study metabolic control of ND in human midbrain-derived neurons without the use of toxicants or other direct disturbance of cellular metabolism.
