Purpose Of Review: The aim of this review is to evaluate the recent evidence of the role of metabolism in systemic sclerosis (SSc), highlighting specific aberrations and to appraise the feasibility of targeting these therapeutically.
Recent Findings: SSc is an autoimmune disease that is characterised by three facets: vascular problems, inflammation, and fibrosis. The fibrosis primarily affects the skin and lungs and currently, no antifibrotic treatment has been found effective. In recent years a renaissance in metabolism research has begun with renewed vigour in the role of metabolism in disease, particularly in the immune system. Alterations in glycolysis and utilisation of specific metabolic pathways in specific cell types have been associated with specific diseases. Most recently alterations in glycolysis and glutaminolysis have been determined in SSc fibroblasts mediating fibrosis. Reduced nicotinamide adenine dinucleotide levels have also been described in SSc.
Summary: Specific metabolic aberrations have been described in SSc and this may lead to novel therapeutic targets in this disease.

Amyotrophic lateral sclerosis in a patient with chronic lymphocytic leukaemia and drug related sarcoid-like reaction.
BMC Neurol
January 2025
Department of Neurology, Wessex Neurological Centre, University Hospital Southampton, Southampton, UK.
Article Synopsis
- Sarcoid-like reaction (SLR) is an immune response affecting lymph nodes and organs, which doesn't fulfill the criteria for systemic sarcoidosis, and can be associated with certain diseases like Chronic lymphocytic leukaemia (CLL) and Amyotrophic lateral sclerosis (ALS).
- A 60-year-old male patient with treated CLL developed ALS symptoms following exposure to Venetoclax and Rituximab, presenting with rashes and weakness that progressed over a year.
- Diagnosis complications included atypical signs and symptoms, leading to misdiagnosis of neurosarcoidosis and challenges in treatment, despite initial interventions with prednisolone and infliximab.
The Role of Exosomes in Medical Dermatology: Literature Review and Update.
J Cosmet Dermatol
January 2025
Clinical Research Center of the Carolinas, Charleston, South Carolina, USA.
Background: Exosomes are extracellular vesicles, composed of a phospholipid bilayer, that are primarily derived from stem cells. The contents of exosomes can be incorporated into the tissue in which they are introduced, which presents a unique therapeutic option.
Aims: Exosomes have been investigated as a treatment for a number of medical ailments, but the literature supporting these indications is inconclusive.
Analysis of healthcare utilization before the diagnosis of radiologically isolated syndrome.
Mult Scler
January 2025
Rennes University, EHESP, CNRS, Inserm, ARENES UMR 6051, RSMS U 1309, Rennes, France.
Background: Previous studies have shown that people with multiple sclerosis (MS) had frequent healthcare visits up to 10 years before being diagnosed but with no information from magnetic resonance imaging (MRI) scans of the connection with the radiologically isolated syndrome (RIS).
Objective: To analyze healthcare use 3 years before the RIS diagnosis.
Methods: We examined healthcare usage before the first scan in RIS cases from 2010 to 2019.

Metabolic alterations, including hypermetabolism, lipid imbalances, and glucose dysregulation, are pivotal contributors to the onset and progression of Amyotrophic Lateral Sclerosis (ALS). These changes exacerbate systemic energy deficits, heighten oxidative stress, and fuel neuroinflammation. Simultaneously, gastrointestinal dysfunction and gut microbiota (GM) dysbiosis intensify disease pathology by driving immune dysregulation, compromising the intestinal barrier, and altering gut-brain axis (GBA) signaling, and lastly advancing neurodegeneration.
