Transduction mechanisms of porcine chondrocyte inorganic pyrophosphate elaboration. (1/116)

OBJECTIVE: To investigate cellular signaling mechanisms that influence chondrocyte production of inorganic pyrophosphate (PPi), which promotes calcium pyrophosphate dihydrate (CPPD) crystal deposition. METHODS: Articular chondrocyte and cartilage cultures were stimulated with protein kinase C (PKC) activator and adenyl cyclase activator. Generation of extracellular PPi was measured. RESULTS: Adenyl cyclase activation resulted in diminished pyrophosphate generation. PKC activation stimulated pyrophosphate elaboration. CONCLUSION: Two signaling pathways, cAMP and PKC, modulate generation of extracellular pyrophosphate by cartilage and chondrocytes. They are novel targets for potentially diminishing extracellular pyrophosphate elaboration that leads to CPPD crystal deposition.  (+info)

Myelopathy due to calcification of the cervical ligamenta flava: a report of two cases in West Indian patients. (2/116)

Two cases of cervical myelopathy due to calcification of the ligamenta flava (CLF) are described for the first time in black patients from the French West Indies. A pre-operative CT scan differentiated the diagnosis from one of ossification of the ligamenta flava. Microanalysis on the operatively excised specimen in one patient revealed a mixture of calcium pyrophosphate dihydrate crystals and hydroxypatite crystals. Poor outcome in one patient contrasting with excellent recovery in the other one, who had undergone posterior decompressive laminectomy, emphasizes the importance of surgery in the management of CLF.  (+info)

Most calcium pyrophosphate crystals appear as non-birefringent. (3/116)

OBJECTIVE: To determine the proportion of calcium pyrophosphate dihydrate (CPPD) crystals that appear as non-birefringent when observed under the polarised light microscope. METHODS: Two observers examined independently 10 synovial fluid samples obtained during an episode of arthritis attributable to CPPD crystals. Ten synovial fluid samples from patients with acute gout were used as a reference. The examination was performed after placing a fluid sample in a Niebauer haemocytometric chamber; a crystal count was done first under ordinary light, then in the area corresponding to a 0.1 ml, under polarised light RESULTS: The percentages of birefringence appreciated for CPPD were 18% (confidence intervals (CI) 12, 24) for observer 1, and 17% (CI 10, 24) for observer 2 (difference NS). The percentages of birefringence for monosodium urate were 127% (CI 103, 151) for observer 1 and 107% (CI 100, 114) for observer 2 (difference NS). Percentages above 100% indicate that crystals missed under ordinary light became apparent under polarised light. CONCLUSION: Only about one fifth of all CPPD crystals identified by bright field microscopy show birefringence when the same synovial fluid sample is observed under polarised light. If a search for CPPD crystals is conducted under polarised light, the majority of the crystals will be missed. Ordinary light allows a better rate of CPPD crystal detection but observation under polarised light of crystals showing birefringence is required for definitive CPPD crystal identification.  (+info)

Extracellular signal-regulated kinase 1/extracellular signal-regulated kinase 2 mitogen-activated protein kinase signaling and activation of activator protein 1 and nuclear factor kappaB transcription factors play central roles in interleukin-8 expression stimulated by monosodium urate monohydrate and calcium pyrophosphate crystals in monocytic cells. (4/116)

OBJECTIVE: Monosodium urate monohydrate (MSU) and calcium pyrophosphate dihydrate (CPPD) crystals cause acute gout and pseudogout, respectively. Because acute gout and pseudogout appear to be dependent on interleukin-8 (IL-8)-induced neutrophil ingress, this study was undertaken to define and compare how MSU and CPPD crystals stimulate IL-8 messenger RNA (mRNA) expression in mononuclear phagocytes. METHODS: MSU and CPPD crystal-induced mitogen-activated protein kinase (MAPK) signal transduction and IL-8 transcriptional activation were studied in human monocytic cells, using the THP-1 cell line. RESULTS: MSU and CPPD crystals (0.5 mg/ml) induced activation of c-Jun N-terminal kinase, extracellular signal-regulated kinase 1 (ERK-1)/ERK-2, and p38 MAPK pathways in THP-1 cells. Activation of the ERK-1/ERK-2 pathway was essential for MSU and CPPD crystal-induced IL-8 mRNA expression, whereas the p38 pathway played a greater role in IL-8 mRNA expression in response to CPPD crystals in comparison with MSU crystals. Both crystals induced the binding of nuclear factor kappaB (NF-kappaB), including the NF-kappaB complex c-Rel/RelA, and activator protein 1 (AP-1, including N-terminal phosphorylated c-Jun) to the IL-8 promoter. Both crystals induced transcriptional activation of the IL-8 promoter, which was dependent on activation of c-Rel/RelA and AP-1. Activation of the NF-IL-6 transcription factor played a lesser role. Finally, crystal-induced IL-8 promoter activation was mediated by activation of the ERK-1/ERK-2 pathway, as demonstrated by transfection of dominant-negative raf-1. CONCLUSION: These results indicate that ERK-1/ ERK-2 signaling and transcriptional activation through AP-1 and NF-kappaB are essential for the induction of IL-8 expression in mononuclear phagocytes in response to CPPD and MSU crystals.  (+info)

Calcification of the cervical ligamentum flavum--case report. (5/116)

A 52-year-old male presented with calcification of the cervical ligamentum flavum manifesting as hypesthesia of the bilateral middle, ring, and little fingers and ulnar halves of both forearms, as well as motor weakness in the bilateral upper extremities and gait disturbance. Cervical x-ray tomography detected a round calcified mass on the posterior wall of the cervical canal at the C-5 level. Computed tomography showed the round, nodular calcified mass more clearly. Magnetic resonance imaging showed an epidural low intensity mass compressing and distorting the cervical cord at the C-5 level on both T1- and T2-weighted images. Administration of gadolinium-diethylenetriaminepenta-acetic acid caused marginal enhancement of the mass. The lesion was eventually removed by posterior laminectomy. The mass was composed of a very hard crystal-like calcified deposition in the ligamentum flavum. X-ray diffraction analysis of the histological specimen showed calcium pyrophosphate dihydrate (CPPD) and hydroxyapatite in the crystal-like substance, confirming that CPPD is responsible for calcification of the cervical ligamentum flavum.  (+info)

Deposition of calcium pyrophosphate in tissue after revision arthroplasty of the hip. (6/116)

We reviewed histologically the incidence and pathogenesis of the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in the pseudocapsule, femoral and acetabular membranes and periprosthetic tissue at revision of 789 cases of failed total hip replacement. In 13, periprosthetic tissues were found to have deposits of CPPD crystals in areas of cartilaginous metaplasia; four also showed evidence of localised deposition of amyloid. None of the patients had a history of chondrocalcinosis in the hip or other joints. Cartilaginous metaplasia and other changes in periprosthetic tissues may predispose to the deposition of CPPD and associated localised amyloid.  (+info)

Retro-odontoid massive calcium pyrophosphate crystal deposition--case report. (7/116)

An 86-year-old male presented with progressive myelopathy due to retro-odontoid massive deposits of calcium pyrophosphate dihydrate (CPPD) crystals. Magnetic resonance imaging revealed a non-enhanced isointense extradural mass on the T1-weighted image and heterogeneously intense mass on the T2-weighted image. Computed tomography showed typical punctate and linear calcifications within the mass. The mass was resected via a lateral approach resulting in marked improvement of the symptoms. Histological examination revealed birefringent rhomboid crystals consistent with CPPD. CPPD deposition should be considered in the differential diagnosis of retro-odontoid extradural mass because surgical therapy is beneficial even for elderly patients.  (+info)

Inhibition of TNF-alpha-induced neutrophil apoptosis by crystals of calcium pyrophosphate dihydrate is mediated by the extracellular signal-regulated kinase and phosphatidylinositol 3-kinase/Akt pathways up-stream of caspase 3. (8/116)

The role of protein kinases in the inhibition of TNF-alpha associated apoptosis of human neutrophils by crystals of calcium pyrophosphate dihydrate (CPPD) (25 mg/ml) was investigated. We monitored the activities of the p44 extracellular signal-regulated kinase 1 (ERK1) and p42 ERK2 mitogen-activated protein (MAP) kinases and phosphatidylinositol 3-kinase (PI3-K)-regulated protein kinase B (Akt) in neutrophils incubated with TNF-alpha and CPPD crystals, separately and in combination, in parallel with the endogenous caspase 3 activity and DNA fragmentation. CPPD crystals were observed to induce a robust and transient activation of ERK1, ERK2, and Akt, whereas TNF-alpha produced only a modest and delayed activation of Akt. In the presence of TNF-alpha, Akt activity was enhanced, and CPPD crystal-induced activation of ERK1 and ERK2 was more sustained than with CPPD crystals alone, but TNF-alpha itself reduced the basal phosphotransferase activities of these MAP kinases. Preincubation with the MAP kinase kinase (MEK1) inhibitors PD98059 (20 ng/ml) and U0126 (250 nM), or the PI3-K inhibitors wortmannin (100 nM) and LY294002 (50 microM) repressed the activation of ERK1, ERK2, and Akt in association with CPPD crystal incubation, in the absence or presence of TNF-alpha. Furthermore, the inhibition of the Mek1/Mek2-->ERK1/ERK2 or PI3-K/Akt pathways reversed CPPD crystal-associated suppression of TNF-alpha-induced caspase 3 activation and neutrophil apoptosis. Together, these results indicate that CPPD crystals function to induce acute inflammatory responses through ERK1/ERK2 and PI3-K/Akt-mediated stimulation of neutrophil activation and repression of apoptosis.  (+info)

Mg is a divalent cation mostly located intracellularly. It plays an important role in enzymatic processes. In healthy individuals homeostasis of Mg is regulated effectively, as sufficient mechanisms in the gastrointestinal tract and the kidney exist. However, if these mechanisms are affected in underlying disease, Mg depletion can cause a wide range of symptoms such as neuromuscular manifestations (muscular cramps, vertigo, tetany), cardiac and vascular manifestations (arrhythmias, hypertension), metabolic sequels and psychiatric manifestations (depression, fatigue) [11, 12].. As seen in this case, severe Mg depletion resulted in CPPD deposition with clinical manifestations of chronic inflammatory arthritis [13-16] and was responsible for muscular weakness, fatigue and the depressive episode.. Chondrocalcinosis, is defined as the deposition of calcium pyrophosphate dihydrate in hyaline or fibrous cartilage [14]. In radiography delicate linear calcification of the cartilage can be seen.

Calcium deposition is often seen at the triangular fibrocartilage of the wrist. Subchondral sclerosis, joint space narrowing, subchondral cyst formations which may be quite large, and intraarticular bodies from subchondral osseous collapse and fragmentation are all findings which can be seen in patients with CPPD disease. These radiographic abnormalities are most common at the radiocarpal articulation and at the 2nd and 3rd metacarpophalangeal joints. Additionally, there may a shift in the normal alignment of the scaphoid and lunate and narrowing at the midcarpal compartment. Differential Diagnosis:. CPPD disease causes destruction of cartilage which can lead to radiographic findings similar to osteoarthritis. Sites of involvement are useful for differentiating the two since the radiocarpal compartment of the wrist is not a common location for osteoarthritis. Lack of an erosive process at the MCP joint differentiates CPPD crystal deposition disease from rheumatoid arthritis. Greater propensity ...
Milwaukee shoulder syndrome (apatite-associated destructive arthritis) is a rheumatological condition similar to calcium pyrophosphate dihydrate deposition disease (CPPD). It is associated with periarticular or intraarticular deposition of hydroxyapatite crystals. Crystal deposition in the joint causes the release of collagenases, serine proteases, elastases, and interleukin-1. This precipitates acute and rapid decline in joint function and degradation of joint anatomy. Subsequently disruption of the rotator cuff ensues. Along with symptomatology, the disease typically presents with positive radiologic findings, often showing marked erosion of the humeral head, cartilage, capsule, and bursae. Though rare, it is most often seen in females beginning in their 50s or 60s. Diagnosis is made with arthrocentesis and Alizarin Red staining along with clinical symptoms. Signs and symptoms may include the following: Limited active range of motion, usually unrestricted passive range of movement (early) ...

The interaction of particulates with resident macrophages is a consistent feature in certain forms of crystal-induced inflammation, for example, in synovial tissues, lung, and the peritoneum. The mitogenic activity of basic calcium phosphate (BCP) crystals and calcium pyrophosphate dihydrate (CPPD) crystals on synovial fibroblasts has been considered relevant to the synovial hyperplasia observed in crystal-induced arthritis. The aim of the study was to determine whether microcrystals such as these could enhance macrophage survival and induce DNA synthesis, thus indicating that they may contribute to the tissue hyperplasia. Murine bone-marrow-derived macrophages were treated in vitro with microcrystals, the cell numbers were monitored over time, and DNA synthesis was measured as the incorporation of [methyl-3H]thymidine (TdR). We report here that BCP, monosodium urate, talc, and, to a lesser extent, CPPD crystals promote macrophage survival and DNA synthesis; the latter response is particularly striking
Methods A web-based exercise and subsequent patient-based exercise were carried out. A panel of 30 OMERACT members, participated at the web-based exercise by evaluating twice a set of US images for the presence/absence of CPPD. Afterwards, 19 members of the panel met in Siena, Italy, for the patient-based exercise. During the exercise, all sonographers examined twice eight patients for the presence/absence of CPPD at the same joints. Intraoberserver and interobserver kappa values were calculated for both exercises. ...
Osteoarthritis is a common feature, most often affecting the knees, shoulders, hips, and hands. Single or multiple joints may be affected. Hypertrophy of cartilage initially produces radiographic widening of the joint space. The newly synthesized cartilage is abnormally susceptible to fissuring, ulceration, and destruction. Ligamental laxity of joints further contributes to the development of osteoarthritis. Cartilage degrades, the joint space narrows, and subchondral sclerosis and osteophytes develop. Joint examination reveals crepitus and laxity. Joint fluid is noninflammatory. Calcium pyrophosphate dihydrate crystals are found in the cartilage in some cases of acromegaly arthropathy and, when shed into the joint, can elicit attacks of pseudogout. Chondrocalcinosis may be observed on radiographs. Back pain is extremely common, perhaps as a result of spine hypermobility. Spine radiographs show normal or widened intervertebral disk spaces, hypertrophic anterior osteophytes, and ligamental ...
Iron was readily demonstrated in chondrocytes in 3 of 4 hemochromatosis articular cartilages studied. Either apatite, calcium pyrophosphate dihydrate crystals, or both were found in all cartilages including those of 3 patients who had no radiographic or light microscopic evidence of calcification. These crystals, which may be secondary to degenerative changes or may play a role in cartilage degeneration, were not seen in any consistent morphologic relationship with the iron deposits. In fact, apatite was found in one cartilage in which no iron was identified in the sections studied. If iron, as demonstrated in the chondrocytes, is contributing to the calcium crystal deposition, it would most likely do so indirectly, for example by altering chondrocyte enzymes or connective tissue components.

OBJECTIVE: To evaluate the ability of baseline hand radiographs to predict the diagnosis 2 years later in a cohort of patients with early arthritis. METHODS: A total of 258 patients with arthritis onset within the previous year were evaluated. At baseline, all patients underwent a standardized evaluation including laboratory tests and radiographs. Hand radiographs were read by a blinded observer who used a standardized procedure for detecting features of crystal deposition diseases and rheumatoid arthritis (RA). After 30 +/- 11.3 months, the final diagnosis was established by a panel of rheumatologists. All radiographs were evaluated. RESULTS: Significant associations were found between radiographic features and a clinical diagnosis of RA, calcium pyrophosphate dihydrate (CPPD) arthritis, and hydroxyapatite arthritis. No radiographic abnormalities suggesting psoriatic arthritis or gout were seen. The sensitivities of hand radiographs for diagnosing CPPD or hydroxyapatite arthritis ranged from ...

OBJECTIVE: To test the hypothesis that high concentrations of extracellular inorganic pyrophosphate (PPi), which associate with increased cell synthesis and turnover in cartilage, may act as a marker for structural outcome in knee osteoarthritis (OA). METHOD: One hundred and thirty five consecutive patients referred to hospital with knee OA (59 men, 76 women; mean age 71 years, range 41-88) were followed prospectively for a median of 2.5 years (interquartile range 1.75-3.0). Synovial fluid (SF) aspirated at presentation (202 OA knees: 68 bilateral, 66 unilateral) was assessed for PPi content by radiometric assay. Knee radiographs at presentation and at final review were assessed for change in global (Kellgren) and individual features (narrowing, osteophyte, sclerosis, cyst, attrition) of OA. RESULTS: The median SF PPi level was 10.5 mumol (range 0.07-72.4). At baseline, high PPi was significantly associated with presence of calcium pyrophosphate crystals, chondrocalcinosis, and bone attrition. ...

Chronic CPP crystal inflammatory arthritis: Chronic inflammatory oligoarthritis or polyarthritis associated with CPPD. Patients have occasional systemic upset with elevation of CRP and ESR and superimposed flares with characteristics of crystal inflammation (see above). Differential considerations include rheumatoid arthritis and other chronic inflammatory joint diseases in older adults. Imaging findings are similar to those of osteoarthritis, but the dirstribution within the joint is different, with CPPD affecting non-weight-bearing surfaces of joints. It is also usually bilateral and symmetric. Synovial inflammation and joint effusions can also be seen. Osteophytes and osteochondral bodies are commonly present. Subchondral cysts are more prominent than in osteoarthritis, and may form before cartilage loss is radiographically evident. Risk factors for calcium pyrophosphate arthropathy are aging, osteoarthritis, previous joint trauma, metabolic diseases (e.g., the four Hs: hemochromatosis, ...

A few months ago I rather suddenly developed an acute painful swelling at the base of my left big toe. I think Im having an attack of gout, but why me? I wondered. Of course this had to happen on a weekend, when the Family Practice Clinic Id usually go to was closed, as was my Podiatrists office.. I wondered if I could have septic arthritis, an infected joint, but had no obvious reason for this much more frightening diagnosis. I remembered there was also an entity called pseudogout, where the crystals were calcium pyrophosphate, not uric acid.. So I went to the Urgent Care Center our local hospital established a few blocks away from my house. A Family Practice physician examined me and said, I think you have gout, but youll need to go to the hospitals Emergency Department (ED) so they can get some fluid from your joint and decide if its really gout. We dont do that test here. She was also concerned about the rather slim possibility of septic arthritis.. At the ED I was triaged as ...

The diagnosis of calcium pyrophosphate dihydrate crystal deposition disease (CPPD) until recent years has been mainly based on the finding of typical crystals of calcium pyrophosphate dihydrate (CPP) in the synovial fluid of affected patients and on the presence of typical calcifications on plain X-rays ...
Calcium pyrophosphate dihydrate crystals are associated with a range of clinical syndromes, which have been given various names, based upon which clinical symptoms or radiographic findings are most prominent.[11] A task force of the European League Against Rheumatism (EULAR) made recommendations on preferred terminology.[5] Accordingly, calcium pyrophosphate deposition (CPPD) is an umbrella term for the various clinical subsets, whose naming reflects an emphasis on particular features. For example, pseudogout refers to the acute symptoms of joint inflammation or synovitis: red, tender, and swollen joints that may resemble gouty arthritis (a similar condition in which monosodium urate crystals are deposited within the joints). Chondrocalcinosis,[2][3] on the other hand, refers to the radiographic evidence of calcification in hyaline and/or fibrocartilage. Osteoarthritis (OA) with CPPD reflects a situation where osteoarthritis features are the most apparent. Pyrophosphate arthropathy refers to ...
Synonyms: Pseudogout, chondrocalcinosis, pyrophosphate arthropathy.. ICD-9 Codes: Pseudogout, 712.2; CPPD crystal deposition disease, 712.2; chondrocalcinosis, 712.3.. Definition: CPPD crystal deposition disease includes arthritic syndromes associated with CPPD crystal deposition disease in articular tissues. The following definitions are used here:. -Chondrocalcinosis: Calcification of articular cartilage (identified by x-ray).. -Chronic CPPD crystal deposition disease: Structural bone and cartilage abnormalities associated with intraarticular deposition of CPPD crystals.. -Pseudogout: Clinical syndrome of acute synovitis caused by intraarticular CPPD crystal deposition, the most common form of CPPD crystal deposition disease.. Etiology: The cause of CPPD crystal deposition disease is unknown. Formation of CPPD crystals in cartilage may be related to matrix changes or result from elevated levels of calcium or inorganic pyrophosphate. Some cases appear to be hereditary, whereas others are ...
Chondrocalcinosis (CC) most commonly results from calcium pyrophosphate crystal deposition (CPPD). The objective of this study is to examine the association between candidate single-nucleotide polymorphisms (SNPs) and radiographic CC. SNPs in ankylosis human (ANKH), high ferritin (HFE), tissue non-specific alkaline phosphatase (TNAP), ecto-neucleotide pyrophosphatase 1 (ENPP1), and transferrin (TE) genes were genotyped in participants of the Genetics of Osteoarthritis and Lifestyle (GOAL) and Nottingham Osteoarthritis Case-Control studies. Adjusted genotype odds ratio (aORGENOTYPE), the OR for association between one additional minor allele and CC, was calculated and adjusted for age, gender, body mass index (BMI), and osteoarthritis (OA) by using binary logistic regression. Statistical significance was set at P ≤0.003 after Bonferroni correction for multiple tests. The -4bpG | A polymorphism in the 5′ untranslated region (5′ UTR) of ANKH associated with CC after Bonferroni correction. This was
Pseudogout is a type of arthritis that, as the name implies, can cause symptoms similar to gout, but which are a reaction to a different type of crystal deposit. This type of arthritis may be one of the most misunderstood forms, and is often mistaken for gout and other conditions, including RA. Proper diagnosis is important because untreated pseudogout may lead to a severe form of joint degeneration and ongoing inflammation, resulting in chronic disability.. Pseudogout develops when deposits of calcium pyrophosphate crystals accumulate in a joint. Initially, crystals deposit in the cartilage and can cause damage. They also can cause a reaction with inflammation that leads to joint pain and swelling. This can cause more chronic arthritis that mimics osteoarthritis or RA. Knees are most often involved, but wrists, shoulders, ankles, elbows, and hands can be affected. Ultimately, a patient with pseudogout could be incapacitated for days or weeks.. ...

The films of glycine consisting of isolated microcrystals were prepared by spin coating and drying of the aqueous solution. Drying leads to dewetting (arising and growth of the holes) and formation of quasi-regular arrays of microcrystals that form the net structure consisting of Voronoi cells. The time dependence of the hole boundary velocity leading to formation of the straight net segments was proposed. Numerical model of hole nucleation and growth by boundary motion was proposed for the computer simulation. The coincidence of the simulated structures obtained within Kolmogorov alpha-model with experimental structures confirmed the validity of proposed approach ...

Of note in this discussion, however, is the immune systems response to the presence of calcium crystals in developing atherosclerotic lesions in arteries. Cells called macrophages which are first responders to bodily harm show up early in the course of blood vessel injury and set immediately to work eating foreign invaders Pac-Man style. As they gobble up various harmful substances such as oxidized LDL cholesterol or basic calcium phosphate (BCP) crystals, they send out proinflammatory cytokines which are chemical messenger molecules that further activate an immune response. This is a good thing with regards to incoming foreign bodies such as bacteria or dirt from the sidewalk when youve fallen and scraped your knee, but not so good when its an ongoing assault from various environmental insults such as LDL-cholesterol, trans-fats, cigarette smoke, or...too much calcium (more on this later).
