Calcium Pyrophosphate Deposition in Nonhuman Primates

Veterinary Pathology, 1984
Naturally occurring deposition of calcium pyrophosphate has been identified in six rhesus monkeys following acute episodes of trauma and various septicemias. Scanning electron microscopy with energy-dispersive X-ray analytical system and single crystal electron diffraction studies were used to identify the crystals within the articular cartilage.

Pyrophosphate Hydrolysis of Ammonium, Calcium, and Calcium Ammonium Pyrophosphates in Selected Texas Soils

Soil Science Society of America Journal, 1970
Abstract Five soils of varying chemical and mineralogical composition were treated with several pyrophosphates, and the rate of pyrophosphate hydrolysis determined. Pyrophosphate hydrolysis was a function of the pyrophosphate compound, soil type, and CaCO 3 treatment.

Acute calcium pyrophosphate deposition arthropathy

JAAPA, 2016
ABSTRACT Acute calcium pyrophosphate deposition (CPPD) arthropathy, also called pseudogout, is common, and becomes more prevalent as patients age. The presenting symptoms are similar to both gout and septic arthritis but may be treated differently. This article describes a typical patient presentation and management from an emergency medicine

The Significance of Intracellular Versus Extracellular Calcium Pyrophosphate Crystals in Diagnosing Calcium Pyrophosphate Crystal Arthritis

The Journal of Rheumatology
ObjectiveAcute and chronic calcium pyrophosphate (CPP) crystal arthritis is characterized by the presence of synovial CPP crystals within a clinically inflamed joint. CPP crystals may be situated intracellularly or extracellularly; however, the clinical significance of their location remains understudied.

Pathophysiology of calcium pyrophosphate deposition

2016
Calcium pyrophosphate (CPP) dihydrate crystals form extracellularly. Their formation requires sufficient extracellular inorganic pyrophosphate (ePPi), calcium, and pro-nucleating factors. As inorganic pyrophosphate (PPi) cannot cross cell membranes passively due to its large size, ePPi results either from hydrolysis of extracellular ATP by the enzyme ...

Treatment of calcium pyrophosphate deposition

2016
The treatment of calcium pyrophosphate crystal deposition (CPPD) is mainly symptomatic. Acute calcium pyrophosphate (CPP) crystal synovitis should be treated with rest, local application of ice packs, joint aspiration, and/or intra-articular corticosteroid injection (once joint sepsis has been excluded).

Investigations of calcium pyrophosphate deposition

2016
Joint aspiration and microscopic examination of the aspirated synovial fluid remains the gold standard for the diagnosis of calcium pyrophosphate crystal deposition (CPPD). If synovial fluid aspiration is not feasible, plain radiography and/or ultrasound scanning may be used to detect chondrocalcinosis (CC) which predominantly occurs due to calcium ...
