BackgroundAmyloid-related imaging abnormalities (ARIA) are a recognized complication of anti-amyloid monoclonal antibodies for Alzheimer's disease (AD). While typically asymptomatic, a subset of patients develops severe clinical symptoms and radiological findings requiring intensive management. Data on their presentation, treatment, and outcomes remain limited.ObjectiveWe report two cases and analyze the clinical features of all published cases of severe symptomatic ARIA, with a focus on associated risk factors, therapeutic approaches, and patient outcomes.MethodsWe report two cases of severe symptomatic ARIA in patients treated with gantenerumab. A systematic review was conducted following PRISMA guidelines using MEDLINE, Web of Science, and manual reference screening. We included case reports and series providing individual-level data on symptomatic ARIA episodes classified as severe by clinical criteria. Demographic, genetic, clinical, radiological, therapeutic, and outcome data were extracted.ResultsThirty-six cases were included (2 new and 34 from 21 publications). Fifteen cases were associated with lecanemab, 10 with gantenerumab, 6 with donanemab, and 5 with other antibodies. Show less

Multitarget drugs are a promising therapeutic approach against Alzheimer's disease. In this work, a new family of 5-substituted indazole derivatives with a multitarget profile including cholinesterase and BACE1 inhibition is described. Thus, the synthesis and evaluation of a new class of 5-substituted indazoles has been performed. Pharmacological evaluation includes Show less

Fusions transcripts have been proven to be strong drivers for neoplasia-associated mutations, although their incidence in T-cell lymphoblastic lymphoma needs to be determined yet. Using RNA-Seq we have selected 55 fusion transcripts identified by at least two of three detection methods in the same tumour. We confirmed the existence of 24 predicted novel fusions that had not been described in cancer or normal tissues yet, indicating the accuracy of the prediction. Of note, one of them involves the proto oncogene TAL1. Other confirmed fusions could explain the overexpression of driver genes such as COMMD3-BMI1, LMO1 or JAK3. Five fusions found exclusively in tumour samples could be considered pathogenic (NFYG-TAL1, RIC3-TCRBC2, SLC35A3-HIAT1, PICALM MLLT10 and MLLT10-PICALM). However, other fusions detected simultaneously in normal and tumour samples (JAK3-INSL3, KANSL1-ARL17A/B and TFG-ADGRG7) could be germ-line fusions genes involved in tumour-maintaining tasks. Notably, some fusions were confirmed in more tumour samples than predicted, indicating that the detection methods underestimated the real number of existing fusions. Our results highlight the potential of RNA-Seq to identify new cryptic fusions, which could be drivers or tumour-maintaining passenger genes. Such novel findings shed light on the searching for new T-LBL biomarkers in these haematological disorders. Show less
