Summary of "Synovial fluid erythrophagocytosis: inflammation or drug-induced change?"

Erythrophagocytosis (EPC) may be detected on microscopy examination by the presence of erythrocytes in the cytoplasm of phagocytes. This type of phagocytosis is rarely described in the medical literature, including medical textbooks. Recent reports mention EPC in peripheral blood samples in severe cold agglutinin disease; in parvovirus-B19 and Epstein Barr virus associated warm IgM-mediated hemolytic anemia; in incompatible transfusion; in sickle cell disease as well as in paroxysmal cold hemoglobinuria and in potassium chlorate poisoning [1,2]. We report our recent finding of EPC in a synovial fluid specimen. This article is protected by copyright. All rights reserved.

IgMCD27 B cells possessed regulatory function and represented the main source of B cell-derived IL-10 in the synovial fluid of osteoarthritis patients.

Synovial inflammation is observed in patients with osteoathritis (OA) and likely contributed to its exacerbation. Regulatory B (Breg) cells are shown to suppress inflammation in various diseases, incl...

Global metabolomic profiling of human synovial fluid for rheumatoid arthritis biomarkers.

The objective of this study was to analyse the metabolomic profiles of rheumatoid arthritis synovial fluid to test the use of global metabolomics by liquid chromatography-mass spectrometry for clinica...

Equine or porcine synovial fluid as a novel ex vivo model for the study of bacterial free-floating biofilms that form in human joint infections.

Bacterial invasion of synovial joints, as in infectious or septic arthritis, can be difficult to treat in both veterinary and human clinical practice. Biofilms, in the form of free-floating clumps or ...

Role of cannabinoid receptor 2 in mediating interleukin-1β-induced inflammation in rheumatoid arthritis synovial fibroblasts.

Recent studies showed that the expression of cannabinoid receptor 2 (CB2), not CB1, is upregulated at both the mRNA and protein levels in rheumatoid arthritis synovial fibroblasts (RASFs), however, li...

Therapeutic effects of Echinococcus granulosus cystic fluid on allergic airway inflammation.

Previous studies showed that Echinococcus granulosus infection reduces allergic airway inflammation in experimentally infected hosts and the cystic fluid of E. granulosus is known to activate regulato...

Medical and Biotech [MESH] Definitions

The clear, viscous fluid secreted by the SYNOVIAL MEMBRANE. It contains mucin, albumin, fat, and mineral salts and serves to lubricate joints.

Non-neoplastic tumor-like lesions at joints, developed from the SYNOVIAL MEMBRANE of a joint through the JOINT CAPSULE into the periarticular tissues. They are filled with SYNOVIAL FLUID with a smooth and translucent appearance. A synovial cyst can develop from any joint, but most commonly at the back of the knee, where it is known as POPLITEAL CYST.

A fluid-filled sac lined with SYNOVIAL MEMBRANE that provides a cushion between bones, tendons and/or muscles around a joint.

Inflammation of a synovial membrane. It is usually painful, particularly on motion, and is characterized by a fluctuating swelling due to effusion within a synovial sac. (Dorland, 27th ed)

The inner membrane of a joint capsule surrounding a freely movable joint. It is loosely attached to the external fibrous capsule and secretes SYNOVIAL FLUID.
