Calcium pyrophosphate deposition disease is defined by the presence of calcium pyrophosphate (CPP) crystals in articular cartilage and is the fourth most common type of arthritis in adults. Despite its high prevalence, the etiology of CPPD disease remains unclear and no specific therapies currently exist. It has been known for several decades that abnormalities of cartilage pyrophosphate metabolism are common in patients with CPPD disease, and this classic work will be reviewed here. Recent studies of rare familial forms of CPPD disease have provided additional novel information about its pathophysiology. This work suggests that CPPD disease occurs through at least two unique and potentially intertwined biomolecular pathways. We are hopeful that a detailed understanding of the components and regulation of these pathways will lead to improved therapies for this common disease.

Large language models for accurate disease detection in electronic health records: the examples of crystal arthropathies.
RMD Open

Division of Rheumatology, Geneva University Hospitals, Geneva, Switzerland.
Objectives: We propose and test a framework to detect disease diagnosis using a recent large language model (LLM), Meta's Llama-3-8B, on French-language electronic health record (EHR) documents. Specifically, it focuses on detecting gout ('goutte' in French), a ubiquitous French term that has multiple meanings beyond the disease. The study compares the performance of the LLM-based framework with traditional natural language processing techniques and tests its dependence on the parameter used.

Chondrocalcinosis, commonly associated with aging, is characterized by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in cartilage and periarticular tissues. Early-onset cases are rare and not well-documented. We report a case of a 60-year-old woman with a probable onset of CPP deposition (CPPD) disease during adolescence, presenting with inflammatory flare-ups and erosive progression following minor trauma.

The radiological manifestations of calcium pyrophosphate deposition (CPPD) revolve around two main axes: the asymptomatic form and CPPD disease. The latter is a consequence of an immune response to calcium phosphate crystals. Chondrocalcinosis is broadly considered the radiographic manifestation of CPPD regardless of whether it is asymptomatic or associated with inflammatory arthritis.

Objective: To develop and validate a patient-reported definition of acute calcium pyrophosphate (CPP) crystal arthritis in people with crystal-proven CPP deposition (CPPD) disease.
Methods: Consecutive patients with crystal-proven CPPD disease from seven centres across four countries were enrolled in a cross-sectional study. In each centre, patient-reported outcomes on the features of acute CPP crystal arthritis were collected.
Coronary artery calcium and atherosclerotic cardiovascular disease risk scores in patients with calcium pyrophosphate deposition disease.

Brigham and Women's Hospital, Division of Cardiology, Boston, USA.
Objective: Calcium pyrophosphate deposition (CPPD) disease is associated with an increased risk for cardiovascular (CV) events. We examined the atherosclerotic burden by coronary artery calcium scores (Agatston score) and compared 10-year atherosclerotic CV (ASCVD) risk scores in patients with vs without chondrocalcinosis, a radiographic marker of CPPD.
Methods: We performed a cross-sectional analysis at an academic medical center, 1991-2022.
