ORCHESTRA Delphi Consensus: Diagnostic and Therapeutic Management of SARS-CoV-2 Infection in Rheumatological Patients.

Introduction: The clinical management of COVID-19 in immunocompromised patients remains a challenge. The aim of this work was to develop a consensus to establish recommendations for the clinical, diagnostic and therapeutic management of patients with rheumatic diseases and COVID-19.

Methods: A panel of 14 international experts was selected and Delphi methodology was used for the consensus, after a systematic literature review.

Long-Term Changes in Parameters of Bone Quality in Kidney Transplant Recipients Treated with Denosumab.

Kidney transplant recipients (KTRs) have an elevated fracture risk. While dual-energy X-ray absorptiometry (DXA) is commonly used to assess areal bone mineral density (aBMD), it does not capture all aspects of bone quality. We investigated the long-term effects on bone DXA-derived indices of bone quality in KTRs treated with denosumab and untreated with denosumab.

Optimization of Transcription Factor-Driven Neuronal Differentiation from Human Induced Pluripotent Stem Cells for Disease Modelling and Drug Screening.

Progress of human brain in vitro models stands as a keystone in neurological and psychiatric research, addressing the limitations posed by species-specific differences in animal models. The generation of human neurons from induced pluripotent stem cells (iPSCs) using transcription factor reprogramming protocols has been shown to reduce heterogeneity and improve consistency across different stem cell lines. Despite notable advancements, the current protocols still exhibit several shortcomings.

TBC1D24 interacts with the v-ATPase and regulates intraorganellar pH in neurons.

The vacuolar ATPase (v-ATPase) is essential for acidification of intracellular organelles, including synaptic vesicles. Its activity is controlled by cycles of association and dissociation of the ATP hydrolysis (V) and proton transport (V) multi-protein subunits. Mutations in genes coding for both v-ATPase subunits and TBC1D24 cause neurodevelopmental disorders with overlapping syndromes; therefore, it is important to investigate their potentially interrelated functions.

Nintedanib in Rheumatoid Arthritis-Related Interstitial Lung Disease: Real-World Safety Profile and Risk of Side Effects and Discontinuation.

Objective: Some concerns remain about the safety of nintedanib in patients with rheumatoid arthritis-related interstitial lung disease (RA-ILD), such as in the presence of comorbidities or in combination with biologic, targeted synthetic, and/or conventional synthetic disease-modifying antirheumatic drugs (DMARDs). In this multicenter study, we retrospectively evaluated the safety of nintedanib in a real-world population of patients with RA-ILD from the Italian Group for the Study of Early Arthritis (GISEA) registry and the possible role of comorbidities and DMARDs on drug safety and withdrawal. Our secondary aim was to investigate the causes of nintedanib discontinuation.
