Diffusion tensor imaging analysis of rheumatoid arthritis patients with neuropsychiatric features to determine the alteration of white matter integrity due to vascular events.

Clin Rheumatol 2022 Jun 25. Epub 2022 Jun 25.

Department of Neuroimaging and Interventional Neuroradiology, All India Institute of Medical Sciences, New Delhi, India.

Introduction: The pathophysiology of neuropsychiatric manifestations in rheumatoid arthritis is not well known. The magnetic resonance imaging of the brain in rheumatoid arthritis demonstrates non-specific findings, and in the majority of cases, magnetic resonance imaging fails to detect an abnormality, even in rheumatoid arthritis patients with neuropsychiatric manifestations. Therefore, we aimed to assess microstructural integrity changes of white matter in patients with rheumatoid arthritis by using different diffusion tensor imaging parameters. Read More

Evidence for the presence of synovial sheaths surrounding the extensor tendons at the metacarpophalangeal joints: a microscopy study.

Arthritis Res Ther 2022 Jun 24;24(1):154. Epub 2022 Jun 24.

Department of Anatomy & Embryology, Leiden University Medical Center, Leiden, The Netherlands.

MRI-detected inflammation around the extensor tendons of metacarpophalangeal (MCP-) joints is prevalent in RA and poses a markedly increased risk of RA development when present in arthralgia patients. Such inflammation is called 'peritendinitis' since anatomy literature reports no presence of a tenosynovial sheath at these tendons. However, the presence or absence of tenosynovium at these extensor tendons has never been studied. Read More

J Hepatol 2022 Jun 21. Epub 2022 Jun 21.

Department of Liver and Gastrointestinal Diseases, Biodonostia Research Institute, Donostia University Hospital, University of the Basque Country (UPV-EHU), Donostia-San Sebastian, Spain; CIBERehd, Instituto de Salud Carlos III (ISCIII), Madrid, Spain; Department of Medicine, Faculty of Medicine and Nursing, University of the Basque Country, UPV/EHU, Leioa, Spain. Electronic address:

Background & Aims: Cholestatic liver injury triggers a wound healing response orchestrated by Kupffer cells (KCs), hepatic stellate cells (HSCs) and other immune cells that leads to peribiliary fibrosis and disease progression. Inflammation is central, particularly that mediated by bacterial components translocating from the gut to the liver, binding to toll-like receptors (TLRs). The triggering receptor expressed on myeloid cells-2 (TREM-2) inhibits TLR-mediated signaling and exerts a protective role in hepatocellular injury and carcinogenesis. Read More

A Summary on the Genetics of Systemic Lupus Erythematosus, Rheumatoid Arthritis, Systemic Sclerosis, and Sjögren's Syndrome.

Clin Rev Allergy Immunol 2022 Jun 24. Epub 2022 Jun 24.

GENYO. Center for Genomics and Oncological Research, Pfizer/University of Granada/Andalusian Regional Government, Av de la Ilustración 114, Parque Tecnológico de La Salud, 18016, Granada, Spain.

Systemic lupus erythematosus, systemic sclerosis, rheumatoid arthritis, and Sjögren's syndrome are four major autoimmune rheumatic diseases characterized by the presence of autoantibodies, caused by a dysregulation of the immune system that leads to a wide variety of clinical manifestations. These conditions present complex etiologies strongly influenced by multiple environmental and genetic factors. The human leukocyte antigen (HLA) region was the first locus identified to be associated and still represents the strongest susceptibility factor for each of these conditions, particularly the HLA class II genes, including DQA1, DQB1, and DRB1, but class I genes have also been associated.

Interleukin-6 Receptor Blockade can Increase the Risk of Nonalcoholic Fatty Liver Disease: Indications From Mendelian Randomization.

Front Pharmacol 2022 7;13:905936. Epub 2022 Jun 7.

Department of Hepatobiliary and Pancreatic Surgery, First Affiliated Hospital of Jilin University, Changchun, China.

Interleukin-6 receptor (IL-6R) blockade has been approved for inflammation-associated diseases and whether it is effective in treating non-alcoholic fatty liver disease (NAFLD) is still unknown. A target-based Mendelian randomization was performed to appraise whether inhibiting the IL-6 signaling pathway IL-6R blockade can reduce the risk of NAFLD. The previously established genetic proxy SNP rs2228145 was mainly used to appraise the therapeutic effects and the genetic-predicted circulating IL-6 level was treated as the exposure with ∼30,000 samples.

The AI-Assisted Identification and Clinical Efficacy of Baricitinib in the Treatment of COVID-19.

Vaccines (Basel) 2022 Jun 15;10(6). Epub 2022 Jun 15.

Imperial College, Hammersmith Hospital, London W12 0NN, UK.

During the current pandemic, the vast majority of COVID-19 patients experienced mild symptoms, but some had a potentially fatal aberrant hyperinflammatory immune reaction characterized by high levels of IL-6 and other cytokines. Modulation of this immune reaction has proven to be the only method of reducing mortality in severe and critical COVID-19. The anti-inflammatory drug baricitinib (Olumiant) has recently been strongly recommended by the WHO for use in COVID-19 patients because it reduces the risk of progressive disease and death.

VEGF Profile in Early Undifferentiated Arthritis Cohort.

Medicina (Kaunas) 2022 Jun 20;58(6). Epub 2022 Jun 20.

The Clinic of Rheumatology, Traumatology Orthopaedics and Reconstructive Surgery, Institute of Clinical Medicine, Faculty of Medicine, Vilnius University, M. K. Čiurlionio str. 21, 03101 Vilnius, Lithuania.

Early undifferentiated arthritis (UA) is a group of inflammatory joint diseases that are not classified under any specific rheumatic or connective tissue disorder and might evolve into chronic inflammatory arthritis or may be a self-limiting condition. Early recognition and treatment are crucial for the future course of the disease. Vascular endothelial growth factor (VEGF) is an angiogenic regulator that induces the growth of new capillary blood vessels, which are important in joint invasion and destruction during the progression of chronic inflammatory arthritis.
