Ultrasound Effectiveness of Steroid Injection for hand Psoriatic Dactylitis: Results from a Longitudinal Observational Study

Introduction: To assess clinical and ultrasound effectiveness of steroid injection (local treatment, LT) into the digital flexor tendon sheath for the treatment of psoriatic dactylitis compared to systemic treatment (ST) alone. Methods: In this observational, multicentre, prospective study, 88 cases of symptomatic hand dactylitis were evaluated clinically and sonographically by high-frequency ultrasound (US) probe in both greyscale (GS) and power Doppler (PD). The presence of flexor tenosynovitis (FT), soft tissue oedema (STO), peritendon extensor inflammation and synovitis was assessed (including DACtylitis glObal Sonographic—DACTOS—score) before treatment, at 1-month (T1) and 3-months (T3) follow-up. LT was proposed to all patients. Patients refusing LT were treated with oral NSAIDs. Patients continued the same baseline csDMARDs and/or corticosteroid therapy during the whole follow-up period. US response was defined for DACTOS score < 3 and US remission for DACTOS score = 0. Results: At T3 evaluation the ST group showed a significantly higher persistence (grade > 1) of FT and STO (p < 0.001 for all) and MCP synovitis (p = 0.001). US remission was achieved only in the LT group (at T3 31% vs. 0, p < 0.001). The percentage of patients with DACTOS < 3 was significantly greater in the LT group compared with ST group, at both T1 (49% vs. 5%, p < 0.001) and T3 evaluation (76% vs. 7%, p < 0.001). In multiple conditional logistic regression analysis, the only factor associated with US remission was LT (T3 odds ratio = 41.21, p < 0.001). Conclusions: US confirmed the effectiveness of steroid injection for dactylitis by demonstrating that it involves the resolution of extra-articular inflammation, in particular FT and STO

Long-lasting uveitis remission and hearing loss recovery after rituximab in Vogt-Koyanagi-Harada disease

Vogt-Koyanagi-Harada disease (VKHD) is a multisystemic disorder characterized by granulomatous panuveitis variably combined with T cell-mediated neurologic and cutaneous manifestations. Early and aggressive treatment with systemic corticosteroids is the mainstay of treatment for VKHD. Additional use of immunosuppressants, intravenous immunoglobulins, and tumor necrosis factor-alpha inhibitors can help the most severely affected patients and work as corticosteroid-sparing agents. We report the case of a young woman with relapsing and multiresistant VKHD who demonstrated a stable remission of both uveitis and high-frequency hearing loss following rituximab intravenous administration (1 g. twice, 2 weeks apart, and 6 months later)

TNFα-inhibitors for ankylosing spondylitis and nonradiographic axial spondyloarthritis

Spondyloarthropathy refers to a group of articular inflammatory diseases that share common genetic, clinical and radiological features in addition to their association with human leucocyte antigen (HLA)-B27 antigen. The aim of therapeutic management of patients with spondyloarthritis is to improve quality of life, control the symptoms of articular inflammation, prevent the structural damage of joints, and preserve the functional abilities, autonomy and social participation of patients. Although disease-modifying anti-rheumatic drugs demonstrate some benefit in the treatment of peripheral arthritis, they have shown to be ineffective for the treatment of patients with axial disease. Biological therapies and new imaging techniques have changed the therapeutic and diagnostic approach to spondyloarthritis. In patients with axial spondyloarthritis for whom conventional therapy with non-steroidal anti-inflammatory drugs has failed, TNFα-inhibitor treatment is currently the only effective therapy. It is more effective in preventing articular damage in peripheral joints compared with joints of the spine. The aim of this review is to summarise the current evidence for treating ankylosing spondylitis and non-radiographic axial spondyloarthritis with TNFα-inhibitor

Caveats and truths in genetic, clinical, autoimmune and autoinflammatory issues in Blau syndrome and early onset sarcoidosis.

Blau syndrome (BS) and early onset sarcoidosis (EOS) are, respectively, the familial and sporadic forms of the pediatric granulomatous autoinflammatory disease, which belong to the group of monogenic autoinflammatory syndromes. Both of these conditions are caused by mutations in the NOD2 gene, which encodes the cytosolic NOD2 protein, one of the pivotal molecules in the regulation of innate immunity, primarily expressed in the antigen-presenting cells. Clinical onset of BS and EOS is usually in the first years of life with noncaseating epithelioid granulomas mainly affecting joints, skin, and uveal tract, variably associated with heterogeneous systemic features. The dividing line between autoinflammatory and autoimmune mechanisms is probably not so clear-cut, and the relationship existing between BS or EOS and autoimmune phenomena remains unclear. There is no established therapy for the management of BS and EOS, and the main treatment aim is to prevent ocular manifestations entailing the risk of potential blindness and to avoid joint deformities. Nonsteroidal anti-inflammatory drugs, corticosteroids and immunosuppressive drugs, such as methotrexate or azathioprine, may be helpful; when patients are unresponsive to the combination of corticosteroids and immunosuppressant agents, the tumor necrosis factor-α inhibitor infliximab should be considered. Data on anti-interleukin-1 inhibition with anakinra and canakinumab is still limited and further corroboration is required. The aim of this paper is to describe BS and EOS, focusing on their genetic, clinical, and therapeutic issues, with the ultimate goal of increasing clinicians' awareness of both of these rare but serious disorders

Predominant ultrasonographic extracapsular changes in symptomatic psoriatic dactylitis: results from a multicenter cross-sectional study comparing symptomatic and asymptomatic hand dactylitis

Objective: Despite diffuse digital swelling, dactylitis may sometimes be asymptomatic. The objective of this study was to compare the clinical and ultrasonographic features of symptomatic with asymptomatic psoriatic arthritis (PsA) dactylitis. Methods: One hundred and twenty-five hand dactylitis were evaluated in a multicenter cross-sectional study for the presence of pain, subjective functional limitation, and tenderness (4-points scale) with the calculation of a Leeds Dactylitis Index (LDI) score. Fingers were subsequently investigated using high-frequency ultrasound (US) both in gray-scale (GS) and power Doppler (PD), for the presence and grading of flexor tenosynovitis, soft tissue edema, subcutaneous PD signal (PDUS), extensor tendon involvement, and joints synovitis. Clinical and US characteristics of symptomatic dactylitic fingers were compared with the asymptomatic dactylitic ones. Results: Symptomatic fingers (n = 80) had a significantly lower dactylitis duration compared to asymptomatic fingers (n = 36) (p < 0.001). Values of LDI, patient VAS-pain, and VAS-functional score were significantly higher in fingers with symptomatic dactylitis (p < 0.001 and p = 0.010, respectively). Symptomatic dactylitis had a higher prevalence of flexor tenosynovitis of grade > 2, soft tissue edema and subcutaneous PDUS signal (p < 0.001). Asymptomatic dactylitis showed a greater prevalence of joint synovitis (both in GS and in PD) than symptomatic dactylitis (p < 0.001). Conclusions: Digital tenderness and pain are linked to US tenosynovitis of grade > 2 and extra synovial abnormalities and conversely asymptomatic dactylitis is associated with joint-based synovitis.Key Points\u2022 Digital tenderness and local pain in psoriatic arthritis dactylitis are strongly associated with flexor tenosynovitis of grade> 2, soft tissue edema, and subcutaneous PD signal.\u2022 In psoriatic arthritis, asymptomatic dactylitis showed a greater prevalence of joint synovitis than symptomatic dactylitis.\u2022 In psoriatic arthritis, ultrasound inflammatory abnormalities are present in about 70% of cold dactylitis which is linked for disease chronicity.\u2022 In psoriatic arthritis, the flexor tendon and adjacent soft tissues play a significant role in symptomatic dactylitis

Effectiveness of steroid injection for hand psoriatic dactylitis: results from a multicentre prospective observational study

Objective: To assess the effectiveness of steroid injection (local treatment, LT) into the digital flexor tendon sheath of dactylitis in psoriatic arthritis (PsA) patients as compared with systemic treatment (ST). Methods: Forty-six PsA patients with a total of 73 dactylitic fingers were assessed in an observational, multicentre, prospective study by the Leeds Dactylitis Index basic (LDI-b) score and evaluated for local pain (visual analogue scale-VAS pain) and functional impairment (VAS-FI). Steroid injection was proposed to all patients. Patients refusing LT were treated with oral NSAIDs. Both the groups continued baseline csDMARDs and/or corticosteroids therapy. The clinical outcomes were measured at baseline, 1 month (T1) and 3 months (T3). Results: The reduction of VAS-pain, VAS-FI and LDI-b values was statistically significant higher in the LT group (24 patients, 38 dactylitic fingers) as compared with the ST group (22 patients, 35 dactylitic fingers), both at T1 (p < 0.001, p < 0.001 and p = 0.008, respectively) and at T3 (p < 0.001, p < 0.001 and p < 0.001, respectively). A clinically meaningful treatment response (defined as a contemporary reduction of at least 5 points in VAS-pain and VAS-FI or as values of VAS-pain and VAS-FI were both 64 2) was observed at T1 in 33 (87%) digits in LT group and in 6 (17%) digits in ST group (p < 0.001). At T3, clinical response improved significantly in both the groups, with significant difference (94% vs 31%, p < 0.001). Conclusions: For the first time, we show the effectiveness of steroid injection into the digital flexor tendon sheath in improving clinical aspects of hand psoriatic dactylitis.Key Points\u2022 Therapy with steroid injection (local treatment, LT), into the digital flexor tendon sheath for the treatment of active dactylitis in psoriatic arthritis patients, is more effective when compared with systemic treatment (ST) alone.\u2022 The reduction of VAS-pain, VAS-functional impairment (VAS-FI) and Leeds Dactylitis Index basic values was statistically significant higher in the LT group as compared with the ST group, both at T1and at T3.\u2022 A clinically meaningful response was observed at T1 in 87% of digits of patients treated with steroid injection and in 17% of digits of the systemic treatment group (p < 0.001). At T3, clinical response improved significantly in both the groups, with significant difference.\u2022 For the first time, findings from this study show that the use of steroid injections into the digital flexor tendon sheath for psoriatic dactylitis could be an effective and safe first-line therapy for psoriatic dactylitis

Biological treatments in Beh\ue7et's disease: beyond anti-TNF therapy.

Beh\ue7et's disease (BD) is universally recognized as a multisystemic inflammatory disease of unknown etiology with chronic course and unpredictable exacerbations: its clinical spectrum varies from pure vasculitic manifestations with thrombotic complications to protean inflammatory involvement of multiple organs and tissues. Treatment has been revolutionized by the progressed knowledge in the pathogenetic mechanisms of BD, involving dysfunction and oversecretion of multiple proinflammatory molecules, chiefly tumor necrosis factor- (TNF-) \u3b1, interleukin- (IL-) 1\u3b2, and IL-6. However, although biological treatment with anti-TNF-\u3b1 agents has been largely demonstrated to be effective in BD, not all patients are definite responders, and this beneficial response might drop off over time. Therefore, additional therapies for a subset of refractory patients with BD are inevitably needed. Different agents targeting various cytokines and their receptors or cell surface molecules have been studied: the IL-1 receptor has been targeted by anakinra, the IL-1 by canakinumab and gevokizumab, the IL-6 receptor by tocilizumab, the IL12/23 receptor by ustekinumab, and the B-lymphocyte antigen CD-20 by rituximab. The aim of this review is to summarize all current experiences and the most recent evidence regarding these novel approaches with biological drugs other than TNF-\u3b1 blockers in BD, providing a valuable addition to the actually available therapeutic armamentarium

The protean ocular involvement in monogenic autoinflammatory diseases: state of the art

Ocular involvement is frequent in the monogenic autoinflammatory disorders and generally occurs as spontaneously recurring inflammatory events at different ocular sites caused by the aberrant release of proinflammatory cytokines, mainly IL-1\u3b2. Over the past decade, we witnessed a significant growth of eye abnormalities associated with idiopathic granulomatous disorders, familial Mediterranean fever, tumor necrosis factor receptor-associated periodic syndrome, mevalonate kinase deficiency, and cryopyrin-associated periodic syndrome. The pathogenetic mechanisms of these disorders have shown the evidence of disrupted cytokine signaling, but the explanation for the heterogeneous ocular involvement remains to be elucidated. We herein review the monogenic autoinflammatory disorders affecting the eye, describing their main clinical features with specific regard to the ocular involvement, which can lead to decreased visual acuity and even blindness, if the primary disorder is undetected or left untreated
