Statins, 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors, are currently the most effective lipid-lowering drugs, effectively reducing the plasma total cholesterol and low-density lipoprotein, while also decreasing three triacylglycerols and increasing plasma high-density lipoprotein to a certain extent. However, the excessive or long-term use of statins can cause in vitro cytotoxicity, in vivo liver injury, liver necrosis, kidney damage, and myopathy in both human beings and animals. Many studies indicate that oxidative stress is involved in the various toxicities associated with statins, and various antioxidants have been evaluated to investigate their protective roles against statin-induced liver, kidney, and muscle toxicities...

Over the last two decades, dozens of applications have emerged for ultrasonography in neuromuscular disorders. We wanted to measure its impact on practice in laboratories where the technique is in frequent use. After identifying experts in neuromuscular ultrasound and electrodiagnosis, we assessed their use of ultrasonography for different indications and their expectations for its future evolution. We then identified the earliest papers to provide convincing evidence of the utility of ultrasound for particular indications and analyzed the relationship of their date of publication with expert usage...

Interstitial lung disease (ILD) is one of the most serious pulmonary complications associated with connective tissue diseases (CTDs), resulting in significant morbidity and mortality. Recently, lung ultrasound examination has appeared as a useful, feasible, non-invasive, radiation-free imaging technique with high sensitivity and specificity for the diagnosis of CTD-associated ILD. In this review, we discuss the literature concerning lung ultrasound findings (B-lines and pleural irregularities) in systemic sclerosis...

The presence of muscular symptoms is common in rheumatological clinical practice, but often the differential diagnosis between muscular involvement in connective tissue diseases, vasculitis and drug-induced myopathy may be difficult. In addition to clinical assessment, laboratory analysis and instrumental examinations, muscle biopsy may help to clarify the diagnosis in patients with muscular involvement. The purpose of this review is to provide a critical analysis of the current medical literature on muscular histopathology, to help clinicians to identify when to perform muscular biopsy and to provide a practical guide to a better understanding of the pathology report...

PGM1, the enzyme responsible for the reversible inter-conversion of glucose-1-P and glucose-6-P, is also involved in glycosylation, leading to a wide range of clinical manifestations, such as congenital malformations, hypoglycemia, hormonal dysregulation, myopathy, hepatopathy, and cardiomyopathy. So far, PGM1 deficiency has not been associated with central nervous system involvement or intellectual disability. Seizures and neurologic involvement in PGM1-CDG were thought to be a consequence of hypoglycemia...

The functional unit in skeletal muscle is the multinucleated myofiber, which is composed of parallel arrays of microfibrils. The myofiber and sarcomere structure of skeletal muscle are established during embryogenesis, when mononuclear myoblast cells fuse to form multinucleated myotubes and develop into muscle fibers. With the myoblasts permanently unable to enter a proliferative state again after they fuse to form the multinucleated myotube, postnatal myofiber growth, muscle homeostasis, and myofiber regeneration are dependent on a myogenic stem cell, the satellite cell...

The skeletal muscle provides movement and support to the skeleton, controls body temperature, and regulates the glucose level within the body. This is the core tissue of insulin-mediated glucose uptake via glucose transporter type 4 (GLUT4). The extracellular matrix (ECM) provides integrity and biochemical signals and plays an important role in myogenesis. In addition, it undergoes remodeling upon injury and/or repair, which is also related to insulin resistance (IR), a major cause of type 2 diabetes (T2DM)...

Patients with advanced malignancies treated with immune checkpoint inhibitors are at increased risk for developing immune-related neurological complications. It is a phenomenon of immunological twist when immunotherapy against co-stimulatory molecules activates previously normal T cells to kill tumor cells but, in so doing, the T cells become unrestrained, triggering other autoimmune diseases for which conventional immunotherapy is needed. The most common autoimmune neurological diseases, usually occurring within 2-12 weeks after immune checkpoint inhibitor initiation, include: inflammatory myopathies, myasthenia gravis, acute and chronic demyelinating polyradiculoneuropathies, vasculitic neuropathies, isolated cranial neuropathies, aseptic meningitis, autoimmune encephalitis, multiple sclerosis and hypophysitis...

Calcium (Ca2+ ) is a key regulator for a large number of cellular functions in all kinds of cells, and small disturbances of Ca2+ homeostasis can severely compromise normal physiology in various tissues and organs. A major mechanism controlling Ca2+ homeostasis is store-operated Ca2+ entry (SOCE), which relies on the concerted action of the reticular Ca2+ sensor STIM1 and the plasma membrane Ca2+ channel ORAI1. Gain-of-function mutations in the respective genes induce excessive Ca2+ entry, and cause tubular aggregate myopathy (TAM) and Stormorken syndrome...

PURPOSE OF REVIEW: Antisynthetase syndrome (ASyS) is an acquired myopathy characterized by the presence of myositis-specific autoantibodies directed against tRNA-synthetases. ASyS is potentially life threatening due to lung involvement and treatment remains a challenge to date. With symptoms not limited to muscles but also involving lung, skin and joints, ASyS appears specific and has a particular pathogenesis, different from the other inflammatory myopathies. This review is intended to discuss the current understanding of ASyS pathogenesis, pointing its current knowledge and also the crucial prospects that may lead to critical improvement of ASyS care...
