Introduction: Viscosupplementation with hyaluronic acid (HA) is indicated for non-responders to non-pharmacological therapy, to analgesics or when non-steroidal anti-inflammatory drugs (NSAIDs) are contraindicated. The aim of this study is to compare the efficacy, safety and costs of three different HA treatments (Sinovial® Forte, sinovial one and hyalgan). Patients and methods: Ninety patients with grade I/II Kellgren–Lawrence knee osteoarthritis were included in three groups, the first was treated with hyalgan (weekly for 5 weeks), the second with Sinovial® Forte (weekly for 3 weeks) and the third group with a single injection of sinovial one. Results: All three treatments were effective, with an average reduction in the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score of 18.9 points for hyalgan, 18.04 points for Sinovial® Forte and 17.92 points for sinovial one. The comparison of the three groups did not show any statistical difference in terms of efficacy. National health system (NHS) and social costs are, respectively, €419.12 and €853.43 for hyalgan, €338.64 and €599.22 for Sinovial® Forte, €221.56 and €308.42 for sinovial one. Conclusion: All three treatments were equally effective with no statistically significant differences; thus, the treatment with sinovial one may be considered as clinically effective as the other two regimens, but with a very efficient cost profile in early symptomatic knee osteoarthritis.

Abstract Objectives Systemic sclerosis (SSc) causes functional and structural microcirculatory dysfunction, affecting also distal extremities. Optical Near-InfraRed Spectroscopy (NIRS) of blood HbO 2 saturation (stO 2) is able to evaluate O 2 delivery/consumption balance in the explored tissue. The NIRS-sensitive camera non-invasively detects stO 2 values in superficial tissues, automatically generating 2D-imaging maps in real time. We aimed at testing whether NIRS hand imaging may evaluate peripheral microcirculatory dysfunction and its spatial heterogeneity in SSc patients compared to controls. Methods Forty SSc patients (aged 55.1 ± 15.6 years) and twenty-one healthy controls (aged 54.3 ± 14.5years, p = 0.89) were studied by palmar hand NIRS-2D imaging. A blood pressure cuff was applied to the forearm and 3 min ischemia was induced. Images were acquired at basal conditions and every 10 seconds during 3 minutes of ischemia and 5 minutes of reperfusion. Five regions of interest were positioned on each fingertip, from the second to the fifth finger and one on the thenar eminence. Results A significant difference was found between controls and SSc patients in basal stO 2 (84.3 ± 7.5 vs. 75.4 ± 10.9%, p < 0.001), minimum stO 2 (65.2 ± 8.0 vs. 53.4 ± 10.1%, p < 0.001) and time to maximum stO 2 during hyperemia (63 ± 38 vs. 85 ± 49 s, p < 0.05). Among clinical characteristics, anti-Scl70 antibody positivity, digital ulcers history and smoke exposure affected NIRS parameters, as well as sildenafil and statins therapy. Conversely, no significant differences were found in NIRS-2D values between different nailfold-videocapillaroscopy patterns. Conclusion NIRS-2D imaging is a simple, automated tool to non-invasively detect regional microcirculatory impairment in SSc, which seems to add significant functional information to the morphological picture of nailfold-videocapillaroscopy.

Objective: In the last years, symptomatic slow-acting drugs for osteoarthritis (SYSADOA) have been vastly studied and have generated considerable interest among clinicians. SYSADOA are generally used as a ground therapy with the main rationale to reduce the consumption of nonsteroidal anti-inflammatory drugs (NSAIDs)and thus limit the related adverse events. Material and Methods: In this study, we evaluated the short-term effect of an oral combination of hyaluronic acid, chondroitin sulfate, and keratin matrix on early symptomatic knee osteoarthritis. Forty patients were treated for 1 month and were allowed to assume analgesics or NSAIDs if necessary. Results: At 2 months, the mean reduction of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score was 36% (p<0.001), and the mean reduction of the WOMAC pains score was 40% (p<0.001). Only two patients reported a sporadic need to assume analgesics; no patient reported any side effect during the study period. Conclusion: This data demonstrates that the oral combination of hyaluronic acid, chondroitin sulfate, and keratin matrix is safe, well tolerated, and shows a rapid action reducing pain and i m proving joint function and stiffness in early symptomatic knee osteoarthritis.

Abstract: The high rates of cardiovascular (CV) mortality and morbidity observed in patients with systemic autoimmune diseases (SADs) cannot be fully explained by traditional atherosclerosis risk factors as standard therapy (i.e. corticosteroids and methotrexate), cytokines and disease activity may all contribute to accelerated atherosclerosis. There is considerable evidence showing that chronic inflammation and immune dysregulation play a pathogenetic role in the development of atherosclerosis in patients with SADs. Chronic inflammation, accelerated atherosclerosis and functional abnormalities of the endothelium suggest that subclinical CV involvement begins soon after the onset of the disease and progresses with disease duration. All cardiac structures may be affected during the course of SADs (valves, the conduction system, the myocardium, endocardium and pericardium, and coronary arteries), and the cardiac complications have a variety of clinical manifestations. As these are all associated with an unfavourable prognosis, it is essential to detect subclinical cardiac involvement in asymptomatic SAD patients, and begin adequate management and treatment early.

Interstitial lung disease (ILD) is a major pulmonary manifestation of connective tissue disease (CTD), leading to significant morbidity and mortality. Chest high-resolution computed tomography (HRCT) is presently considered the diagnostic gold standard for pulmonary fibrosis diagnosis and quantification in the clinical arena. However, not negligible doses of ionizing radiation limit the use of HRCT, especially for serial follow-up in younger female patients. In the past decade, lung ultrasound (LUS) has been proposed to assess ILD by detecting and quantifying sonographic B-lines. Previous studies demonstrate that B-lines have a good diagnostic accuracy, especially high sensitivity, and correlate well with HRCT findings, suggesting LUS as a novel, non-invasive, and non-ionizing imaging method to be used in patients with CTD-ILD. Although preliminary data are promising, challenges and controversies still remain. For example, the mechanisms of B-line generation are not fully understood; the diagnostic accuracy and performance characteristics of LUS partially depend on the scanning scheme and scoring system used; and up-to-date B-lines cannot discriminate the early cellular inflammation from the chronic fibrotic phase in CTD-ILD. Therefore it is important for clinicians to understand the strengths and limitations of LUS in CTD-ILD patients, to maximize its value.

Rheumatoid arthritis (RA) is a chronic disease characterised by inflammation of the synovial tissue in joints, which can lead to joint destruction. The primary aim of the treatment is to control pain and inflammation, reduce joint damage and disability, and maintain or improve physical function and quality of life. In this article, we provide a critical analysis of the recent literature on the novelties in the treatment of RA, with a particular focus on the most relevant studies published over the last two years.
