High prevalence of chondrocalcinosis and frequent comorbidity with calcium pyrophosphate deposition disease in patients with seronegative rheumatoid arthritis.

RMD Open 2022 Jun;8(2)

Ruhr University Bochum, Bochum, Germany

Background: The crystal-induced calcium pyrophosphate deposition disease (CPPD) clinically appearing as pseudogout differs from the mere radiographic finding of chondrocalcinosis (CC) but may cause symptoms resembling rheumatoid arthritis (RA).

Objective: To study the prevalence of CPPD and CC in rheumatic diseases focusing on differences between seropositive and seronegative RA.

Patients And Methods: In a retrospective study design, we analysed records and radiographs of consecutive new patients presenting to our centre between January 2017 and May 2020. Read More

Mutation in the CCAL1 locus accounts for bidirectional process of human subchondral bone turnover and cartilage mineralization.

Rheumatology (Oxford) 2022 Apr 12. Epub 2022 Apr 12.

Dept. Biomedical Data Sciences, Section Molecular Epidemiology, Leiden University Medical Center, Leiden (LUMC), The Netherlands.

Objectives: To study the mechanism by which the readthrough mutation in TNFRSF11B encoding OPG-XL, previously shown to affect binding between OPG and heparan sulphate (HS) causes the characteristic bidirectional phenotype of subchondral bone turnover accompanied by cartilage mineralization in CCAL1 chondrocalcinosis patients.

Methods: OPG-XL was studied by human induced pluripotent stem cells expressing OPG-XL and two isogenic CRISPR/Cas9-corrected controls in cartilage and bone organoids. Osteoclastogenesis was studied with monocytes from OPG-XL carriers and matched healthy controls followed by gene expression characterization. Read More

Chemical Diagnosis of Calcium Pyrophosphate Deposition Disease of the Temporomandibular Joint: A Case Report.

Diagnostics (Basel) 2022 Mar 7;12(3). Epub 2022 Mar 7.

Department of Maxillofacial Surgery, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, 1-5-45 Yushima, Bunkyo, Tokyo 113-8549, Japan.

Calcium pyrophosphate dihydrate (CPPD) deposition disease is a benign disorder characterized by acute gouty arthritis-like attacks and first reported by McCarty. CPPD deposition disease rarely occurs in the temporomandibular joint (TMJ), and although confirmation of positive birefringence by polarized light microscopy is important for diagnosis, it is not reliable because other crystals also show birefringence. We reported a case of CPPD deposition disease of the TMJ that was diagnosed by chemical analysis. Read More

Magnetic resonance imaging of rheumatological diseases.

Pol J Radiol 2022 20;87:e93-e112. Epub 2022 Feb 20.

Department of Radiology, University of New Mexico School of Medicine, Albuquerque, New Mexico, USA.

Magnetic resonance imaging (MRI) is extremely useful in the early diagnosis of rheumatologic diseases, as well as in the monitoring of treatment response and disease progression to optimize long-term clinical outcomes. MRI is highly sensitive and specific in detecting the common findings in rheumatologic diseases, such as bone marrow oedema, cartilage disruption, articular erosions, joint effusions, bursal effusions, tendon sheath effusions, and synovitis. This imaging modality can demonstrate structural changes of cartilage and bone destruction years earlier than radiographs. Read More

Histone Deacetylase Inhibitors Downregulate Calcium Pyrophosphate Crystal Formation in Human Articular Chondrocytes.

Int J Mol Sci 2022 Feb 26;23(5). Epub 2022 Feb 26.

School of Medical Laboratory Science and Biotechnology, College of Medical Science and Technology, Taipei Medical University, Taipei 11031, Taiwan.

Calcium pyrophosphate (CPP) deposition disease (CPPD) is a form of CPP crystal-induced arthritis. A high concentration of extracellular pyrophosphate (ePPi) in synovial fluid is positively correlated with the formation of CPP crystals, and ePPi can be upregulated by ankylosis human (ANKH) and ectonucleotide pyrophosphatase 1 (ENPP1) and downregulated by tissue non-specific alkaline phosphatase (TNAP). However, there is currently no drug that eliminates CPP crystals. Read More

Uremic Toxin Lanthionine Induces Endothelial Cell Mineralization In Vitro.

Biomedicines 2022 Feb 14;10(2). Epub 2022 Feb 14.

Department of Translational Medical Science University of Campania "Luigi Vanvitelli", Via Pansini, Bldg 17, 80131 Naples, Italy.

Vascular calcification (VC) is a pathological event caused by the unusual deposition of minerals in the vascular system, representing the leading cause of cardiovascular mortality in chronic kidney disease (CKD). In CKD, the deregulation of calcium and phosphate metabolism, along with the effect of several uremic toxins, act as key processes conveying altered mineralization. In this work, we tested the ability of lanthionine, a novel uremic toxin, to promote calcification in human endothelial cell cultures (Ea. Read More

Identification of Common Pathogenic Pathways Involved in Hemochromatosis Arthritis and Calcium Pyrophosphate Deposition Disease: a Review.

Curr Rheumatol Rep 2022 02 10;24(2):40-45. Epub 2022 Feb 10.

Research Division, cc-117, Zablocki VA Medical Center, 5000 W. National Ave, Milwaukee, WI, 53295-1000, USA.

Objectives: Arthritis is a common clinical manifestation of hereditary hemochromatosis (HH), and HH is one of a handful of conditions linked to calcium pyrophosphate deposition (CPPD) in joints. The connection between these two types of arthritis has not yet been fully elucidated. In light of new pathogenic pathways recently implicated in CPPD involving bone, we reviewed the literature on the etiology of hemochromatosis arthropathy (HHA) seeking shared pathogenic mechanisms.

Sensing and imaging of PPi using lanthanide-based second near-infrared luminescent probes.

J Mater Chem B 2022 02 16;10(7):1055-1062. Epub 2022 Feb 16.

State Key Laboratory of Natural Medicine, The School of Basic Medical Sciences and Clinical Pharmacy, China Pharmaceutical University, Nanjing, Jiangsu 211198, China.

Inorganic pyrophosphate (PPi), as a biologically active anion, is closely related to physiological activities and several pathological changes. Here, we reported a luminescent nanoprobe for the detection and imaging of PPi based on lanthanide nanoparticles with luminescence at the second near-infrared window modified by the tannic acid and Fe complex. A light-harvesting complex was formed after the coordination of colorless tannic acid with Fe and the luminescence of the nanoparticles was quenched through the inner-filter effect. Read More

Laboratory and Service of Rheumatology, GIGA Research, Centre Hospitalier Universitaire de Liège, University of Liège, 4000 Liège, Belgium.

An inflamed synovial membrane plays a major role in joint destruction and is characterized by immune cells infiltration and fibroblast proliferation. This proteomic study considers the inflammatory process at the molecular level by analyzing synovial biopsies presenting a histological inflammatory continuum throughout different arthritis joint diseases. Knee synovial biopsies were obtained from osteoarthritis (OA; n = 9), chronic pyrophosphate arthropathy (CPPA; n = 7) or rheumatoid arthritis (RA; n = 8) patients. Read More
