We have assessed the nature and significance of musculoskeletal disorders in 166 patients with the commonly encountered forms of hyperlipidaemia attending a lipid clinic. The incidence of musculoskeletal disorders was determined by questionnaire to the patients, inquiries to general practitioners, and a review of hospital records. To ensure the sensitivity of these methods a series of negatively responding cases were seen and examined; none had identifiable musculoskeletal disease. Eight males with type IV hyperlipidaemia had recurrent acute attacks of gout. The only other musculoskeletal disorder possibly attributable to an association with hyperlipidaemia was a transient polyarthritis in 3 patients. This was inflammatory, recurrent, but nondeforming, and involved the small joints of the hand. It did not require any specific therapy or lead to disability. We suggest that, while we have confirmed the association of type IV hyperlipidaemia and gout, there is little evidence for clinically significant arthritis being associated with other commonly presenting forms of hyperlipidaemia, although we accept that the rarely met homozygous familial hypercholesterolaemia may also be complicated by a crystal arthropathy due to the presence of crystalline cholesterol in joints.

The clinical significance of cytoplasmic inclusions(CPI) in synovial fluid(SF) examination was evaluated. We examined SF specimens collected from major rheumatology clinics in the Philadelphia area during the period of January to December 1995. Among 759 patients in the initial study group, 419 cases with established diagnoses and full synovial analyses were included. Their diagnoses and SF analysis results including leukocyte counts, differential counts and wet preparations were collected and analysed. Ninety seven of the 419 SF specimens were found to have CPI. CPI were found in SF from almost all rheumatic diseases. They were most likely to be found in inflammatory arthropathy including rheumatoid arthritis(RA, 46%), juvenile rheumatoid arthritis(JRA, 78%) and psoriatic arthritis(55%). On the contrary, CPI were least common in crystal-induced arthropathy among the inflammatory arthropathy. CPI were found 8 out of 98 gout cases(8%) and 2 among 53 calcium pyrophosphate dihydrate(CPPD) deposition disease(4%). In noninflammatory arthropathy, CPI were found in only 6 cases(6%) out of the 103 osteoarthritis(OA). In RA cases with non-inflammatory SF, 4 of the 20 SF(20%) had CPI while only 6% of OA SF had CPI. OA SF with CPI were all noninflammatory SF. In summary, CPI were a common finding on SF examination. CPI were more likely to be found in inflammatory arthropathy than noninflammatory. Among inflammatory arthropathy, CPI can favor non-crystal arthropathy than crystal arthropathy. Awareness of the presence of CPI is suggested as an addendum to routine SF analysis. Renewed investigation of the several types of CPI may add further to the understanding of joint disease.

A 74-year-old man with chronic lymphocytic leukemia, immune purpura, and gout presented with a painful, swollen ankle after a cat bite to his leg. On aspiration of the ankle, gram negative pleomorphic rods and monosodium urate crystals were seen and Pasteurella multocida was cultured. He was treated with ampicillin/sulbactam, joint aspiration, and intraarticular steroids, with resolution of infection and return of joint function. The syndromes of Pasteurella arthritis and crystal arthropathy with septic arthritis are reviewed.

There have been very few reports in the literature of gout and pseudogout of the spine. We describe six patients who presented with acute sciatica attributable to spinal stenosis with cyst formation in the facet joints. Cytopathological studies confirmed the diagnosis of crystal arthropathy in each case. Specific formation of a synovial cyst was identified pre-operatively by MRI in five patients. In the sixth, the diagnosis was made incidentally during decompressive surgery. Surgical decompression alone was undertaken in four patients. In one with an associated degenerative spondylolisthesis, an additional intertransverse fusion was performed. Another patient had previously undergone a spinal fusion adjacent to the involved spinal segment, and spinal stabilisation was undertaken as well as a decompression. In addition to standard histological examination material was sent for examination under polarised light which revealed deposition of urate or calcium pyrophosphate dihydrate crystals in all cases. It is not possible to diagnose gout and pseudogout of the spine by standard examination of a fixed specimen. However, examining dry specimens under polarised light suggests that crystal arthropathy is a significant aetiological factor in the development of symptomatic spinal stenosis associated with cyst formation in a facet joint.

High serum uric acid levels elevate pro-inflammatory-state gout crystal arthropathy and place individuals at high risk for cardiovascular morbidity and mortality. Genome-wide scans in the genetically isolated Sardinian population identified variants associated with serum uric acid levels as a quantitative trait. They mapped within GLUT9, a Chromosome 4 glucose transporter gene predominantly expressed in liver and kidney. SNP rs6855911 showed the strongest association (p = 1.84 x 10(-16)), along with eight others (p = 7.75 x 10(-16) to 6.05 x 10(-11)). Individuals homozygous for the rare allele of rs6855911 (minor allele frequency = 0.26) had 0.6 mg/dl less uric acid than those homozygous for the common allele; the results were replicated in an unrelated cohort from Tuscany. Our results suggest that polymorphisms in GLUT9 could affect glucose metabolism and uric acid synthesis and/or renal reabsorption, influencing serum uric acid levels over a wide range of values.

Symptomatic gout in an artificial joint is exceptionally rare. We present a 68-year-old male patient who developed progressive knee pain and swelling one year after the cemented total arthroplasty of his left knee. The diagnosis was confirmed by crystal identification in the synovial fluid. Beside thorough workout to rule out infection in a painful and inflamed prosthetic knee, specific history of gout should be sought and fluid aspirate examined cytologically and under polarised light for crystal arthropathy.

The incidence of gout and the clinical manifestation of hyperuricemia continue to rise. In addition to painful acute attacks, chronic gout can lead to the development of crystal arthropathy, tophi, and renal lithiasis, coincidental with declines in quality of life. As a greater appreciation for the associations between hyperuricemia, gout, and certain comorbidities, such as renal impairment and cardiovascular diseases, grows, so does the search for new therapeutic options to both alleviate the painful symptoms of acute gout attacks and reduce the underlying hyperuricemia. This manuscript reviews the pathophysiology of hyperuricemia and gout, and associated comorbidities, and then discusses traditional therapeutic options, newly available agents, and future targets for pharmacologic management.

Crystal arthropathies represent a heterogenic group of skeletal diseases associated with the deposition of mineralised material within joints and periarticular soft tissues. Gout is the most common and pathogenetically best understood crystal arthropathy, followed by basic calcium phosphate and calcium pyrophosphate dihydrate deposition diseases, and, in very rare cases, calcium oxalate crystal arthropathy. These crystals are responsible for different rheumatic syndromes, including acute or chronic synovial inflammation, and also contribute to cartilage degeneration. This review gives an overview of the pathological and clinical changes of these arthropathies.

The clinical diagnosis of gout can be quite precise in clinically typical forms. However, in chronic or atypical forms, such precision tends to be diminished in clinical practice. A cohort of 248 patients with a diagnosis of urate crystal arthropathy was studied, sent with a definite clinical evaluation, and data such as severity of the disease, joint distribution and the presence of tophi were gathered. Precision data was analyzed with respect to the referral diagnosis according to the severity parameters and the type of physician sending the patient. The best diagnostic precision was seen in the monoarticular forms that were sent both by the emergency room as well as by family physicians, but not in those sent by other specialists. The presence of oligoarticular forms reduced significantly the diagnostic precision in all of the specialties referring patients. The presence of tophi did not improve diagnostic precision. Chronic and severe forms of gout are frequently wrongly evaluated from the clinical standpoint.

This article presents the clinical features of crystal arthropathy after knee replacement. The current literature on pseudogout and gout after both total and partial knee replacement is summarized. A case of bilateral pseudogout 8 years after initial total knee arthroplasty (TKA) is used to highlight the clinical characteristics and treatment options for this underrecognized condition. Presentation mimicked a late septic joint arthroplasty with sudden onset of pain and effusion. The patient was treated successfully with an arthrotomy, debridement, synovectomy, polyethylene insert exchange, oral steroids, and nonsteroidal anti-inflammatories. There are no other reported cases of bilateral pseudogout after bilateral TKA.
