Arthrocentesis and Synovial Fluid Analysisin Clinical Practice. Value of Sonography in Difficult Cases
No full textJoint aspiration, or arthrocentesis, is one of the most useful and commonly performed procedures for the diagnosis and treatment of joint diseases. The synovial fluid aspirated may be examined to evaluate the degree of inflammation and, mainly, to detect the presence of some relevant pathogenic agents, such as crystals or microorganisms. In these cases, synovial fluid analysis still represents the best diagnostic procedure. Arthrocentesis is thus particularly required for the diagnosis and management of the acute "hot red joint," which may be considered a true medical emergency because of the morbidity and mortality related to septic arthritis. The most recent recommendations on arthrocentesis confirm the need for the procedure in the presence of synovial effusion of unknown origin, especially if septic or crystal arthritis is suspected. Owing to the importance of this analysis, it is clearly recommended that ultrasonography should be used to facilitate arthrocentesis in difficult cases. Furthermore, ultrasonography may be useful in revealing the presence of synovial fluid before the joint aspiration and, subsequently, distinguishing some aspects characteristic of crystal-induced arthropathies
Mediterranean Food Pattern in Rheumatoid Arthritis
No full textThe Mediterranean diet is based on a pattern of eating closely tied to the Mediterranean region, which includes Greece and southern Italy. Essentially, the traditional diet emphasizes foods from plant sources, limited meat consumption, small amounts of wine and olive oil as the main fat source. The beneficial effects of the Mediterranean diet has been proven not only to cardiovascular diseases but also for diabetes, obesity, arthritis and cancer. Its anti-inflammatory and protective properties are linked to the large presence of omega-3 polyunsaturated fatty acids, vitamins, but especially to the constituents of extra virgin olive oil: oleic acid, phenolic compounds olecanthal, a new recently discovered molecule, with natural anti-inflammatory properties. It has been shown that the Mediterranean diet can reduce disease activity, pain and stiffness in patients with inflammatory arthritis and may thus constitute a valuable support for patients suffering from these diseases
Nutritional guidance in spondyloarthritis: confronting the evidence gap
Full text linkPurpose of review: to summarize current evidence on the role of specific dietary patterns in spondyloarthritis (SpA) management. Recent findings: dietary interventions may offer a novel, complementary strategy to manage symptoms and enhance overall quality of life in many rheumatic diseases, including SpA. Evidence suggests that the Mediterranean diet may have beneficial effects on inflammation and SpA symptoms. Although there is growing interest in the ketogenic diet with some promising results, data is scarce. Some SpA patients may have sensitivities or intolerances to certain foods containing gluten, which can trigger or worsen their symptoms, especially when associated with intestinal inflammation. Hypocaloric diets and weight loss can provide significant benefit in overweight and obese patients with SpA, potentially reducing systemic inflammation. Finally, while the efficacy of probiotics remains a matter of debate, periods of fasting have proven effective in reducing disease activity indices. Summary: the importance of a healthy dietary lifestyle and its potential benefits in symptom management is acknowledged by the majority of the patients. There is an increased need and demand from patients to receive nutritional counseling that should be integrated into routine SpA management to enhance patient outcomes
New biochemical insights into the pathogenesis of osteoarthritis and the role of laboratory investigations in clinical assessment
No full textOsteoarthritis (OA) is among the most frequent diseases in the population and a common cause of pain and disability in adults. The principal disease hallmarks for assessment of OA are still clinical observation and radiographic aspects. However, the efficacy of therapeutic interventions is complicated by the time required to observe radiographic signs, useful for both diagnosis and assessment. Thus, laboratory markers have received growing attention in recent years, in an attempt to improve diagnosis, assessment of disease activity and severity, and evaluation of therapeutic effects. Many biomarkers have been proposed, in particular those reflecting cartilage and bone turnover and synovitis. Among these, COMP, antigenic keratan sulphate, hyaluronan, YKL-40, type III collagen N-propeptide, and urinary glucosyl-galactosyl pyridinoline appear to be the most promising. However, serum or urinary determinations of these molecules are difficult to interpret adequately due to their complex metabolism. New ultrasensitive methods for C-reactive protein have improved the usefulness of this marker, especially in the assessment of disease activity. Routine examination of synovial fluid is still essential for diagnosis and includes leukocyte count and crystal detection; specialized testing includes the evaluation of the levels of markers of local inflammation such as metalloproteinases and cytokines, which appear to be crucial to the pathogenesis of OA
