RESUMEN
OBJECTIVE: The aim of the study is to assess the performance of the DACTOS (DACtylitis glObal Sonographic) score in a PsA dactylitis clinical setting. In particular, we evaluated the ability of DACTOS to identify the affected fingers, its sensitivity to change after treatment, the correlations between DACTOS and clinical parameters, and the capacity of the score to identify the treatment responders. METHODS: Forty-six consecutive patients with symptomatic PsA hand dactylitis were enrolled. A total of seventy-three dactylitic digits were evaluated clinically and sonographically before and after treatment in this observational and prospective study. Clinical assessment included the Leeds Dactylitis Index-basic (LDI-b) score and visual analogue scales for pain (VAS-p) and functional impairment (VAS-FI). Sonographic lesions were investigated using high-frequency ultrasound with grey scale and power Doppler features according to the DACTOS score. Correlations between the DACTOS score and the clinical parameters were assessed at baseline, 1 month (T1) and 3 months (T3). RESULTS: We observed significant improvements in all of the assessed clinical parameters and the DACTOS scores after dactylitis treatment. There was a statistically significant correlation between the variation of all clinical parameters (VAS-p, VAS-FI and LDI-b) and the DACTOS score at T1 and T3 evaluations. We found statistically significant differences in the DACTOS score between clinical responder and non-responder groups (P < 0.001) and between clinical remission and non-remission groups (P < 0.001). CONCLUSION: The DACTOS score performs well in real-life clinical settings in terms of sensitivity to change and correlations with clinical features in PsA dactylitis.

OBJECTIVES: Dactylitis is one of the most typical features of psoriatic arthritis (PsA), with a high lifetime prevalence and inclusion in PsA clinical indices. Musculoskeletal ultrasonography (Msk-US) can readily detect inflammatory involvement of finger anatomical structures particular to dactylitis and monitor therapeutic effects. In this study, we aim to identify the characteristic lesions in PsA dactylitis of the hands, assess the reliability of Msk-US in scoring those lesions and develop a DACTylitis glObal Sonographic (DACTOS) score. METHODS: After a systematic literature review on the use of Msk-US in PsA dactylitis, 12 rheumatologists participated in a three-round Delphi procedure and consensus meeting to agree on the sonographic elementary lesions characterising dactylitis and on the composition of a global sonographic score. Then, a web-based and a patient-based intra-rater and inter-rater reliability exercise was performed to assess those lesions included in the score. RESULTS: DACTOS score was obtained by summing the scores of each lesion selected in the Delphi survey: subcutaneous soft tissue oedema, flexor tenosynovitis, peritendon extensor inflammation and synovitis. The DACTOS score ranges from 0 to 25. In the reliability exercises, we obtained moderate-to-excellent agreement for the sonographic lesions included in the score. CONCLUSIONS: The novel DACTOS score is a reliable measure to interpret the multiple characteristic sonographic features of dactylitis. The DACTOS score provides a useful global analysis of dactylitis of the hand and can represent a support to clinical diagnosis as well as a useful tool for the management and research in patients with PsA with dactylitis.

OBJECTIVES: The aim of this study was to explore the link between specific sonographic findings and Leeds Dactylitis Index basic (LDI-b) score in psoriatic arthritis (PsA) patients with hand dactylitis. METHODS: Ninety-one hand dactylitis were evaluated in a multicentre study for the presence of pain, functional limitation and tenderness (2-point scale) and LDI-b score. Dactylitic fingers were investigated using high-frequency US in grey scale (GS) and power Doppler (PD). According to median LDI-b score value of 12, fingers were then divided into two groups and categorised into quartiles on the basis of the value of ratio of circumference. RESULTS: Dactylitic fingers with a LDI-b score >12 showed a significantly higher prevalence of GS flexor tenosynovitis (p=0.015), PD flexor tenosynovitis (p=0.001) and soft tissue oedema (p=0.004), when compared with those with those with LDI-b score <12. GS synovitis at proximal interphalangeal (PIP) level (p=0.003) showed more frequent in dactylitic fingers with a LDI-b score <12, than those with a higher LDI-b value. Fingers in the fourth quartile showed a significantly higher prevalence of GS flexor tenosynovitis of grade ≥2 (p=0.046) and joint synovitis of grade ≥2 at PIP level (p=0.028). CONCLUSIONS: We found that high values of LDI are associated with US flexor tenosynovitis and soft tissue oedema in PsA dactylitis. Results suggest a potential role of PIP joint synovitis in the genesis of hand digital swelling and of extra-articular structures alterations in determining the LDI score.

Large-vessel vasculitides comprise giant cell arteritis and Takayasu's arteritis. In both conditions, early changes consist of transmural inflammation of the arterial wall, while later complications include lumen changes, such as stenoses or aneurysms. Colour Doppler sonography has the ability to depict the arterial wall as well as the lumen, and is therefore ideally suited both to diagnose early vasculitis and to monitor patients over time. In this review article, we addressed the following issues: 1) the role of colour Doppler sonography in the diagnosis of large-vessel vasculitis and its common pitfalls; 2) whether colour Doppler sonography can increase the yield of temporal artery biopsy in giant cell arteritis; 3) the role of colour Doppler sonography in monitoring patients with LVV over time; and 4) how colour Doppler sonography performs compared to other imaging techniques.

OBJECTIVE: The aim of this study was to assess the usefulness of colour duplex sonography (CDS)-guided temporal artery biopsy (TAB) for the diagnosis of GCA in patients with suspected GCA. METHODS: From September 2009 through December 2012, 112 consecutive patients with suspected GCA were randomized to undergo CDS-guided TAB or standard TAB. All patients underwent temporal artery physical examination and temporal artery CDS prior to TAB. CDS of the temporal artery was performed by the same ultrasonographer, who was unaware of the patient's clinical data, and all TABs were evaluated by the same pathologist. Seven patients in whom biopsy failed to sample temporal artery tissue were excluded from the analysis. RESULTS: Fifty patients were randomized to undergo CDS-guided TAB and 55 patients to standard TAB. Except for a younger age in patients who underwent standard TAB (P = 0.026), no significant differences were observed between the two groups. There were no significant differences in the frequencies of positive TAB for classic transmural inflammation (28% vs 18.2%) or for periadventitial small vessel vasculitis and/or vasa vasorum vasculitis (6% vs 14.5%) between the two groups. No significant differences in the frequency of positive TAB in the two groups were observed when we excluded the patients treated with glucocorticoids and when we stratified the patients of the two groups for the presence or absence of the halo sign. CONCLUSION: Our study showed that CDS-guided TAB did not improve the sensitivity of TAB for diagnosing GCA.

This paper reviews the rheumatological manifestations of scurvy, based on articles published in English from 1965 until October 2014, with a particular focus on rheumatological manifestations. Scurvy is a rare, uncommon disease in developed countries. Due to its clinical heterogeneity, the disease can easily mimic rheumatologic conditions leading to a delay in diagnosis and treatment.

OBJECTIVE: In this study we aimed to describe the magnetic resonance imaging (MRI) pattern of the distribution of bone marrow edema (BME) and joint erosion in hands and wrists of patients with systemic lupus erythematosus (SLE) with arthritis in comparison with rheumatoid arthritis (RA) and healthy subjects (H). METHODS: SLE patients with arthritis (n = 50), patients with RA (n = 22), and H (n = 48) were enrolled. Every patient underwent a non-dominant hand (2nd-5th metacarpophalangeal joints) and wrist MRI without contrast injection with a low-field extremity dedicated 0.2-Tesla instrument. RESULTS: BME was observed in two SLE patients in the hand (4%) and in 15 in the wrist (13%) versus three (30%), and 14 (63%) RA patients. No BME was found in H. Erosions were observed in the hand in 24 SLE patients (48%), 15 RA patients (68%), and 9 H (18 %); in the wrist, in 41 (82%) SLE, all RA and 47 (97%) H. The cumulative erosive burden in SLE was significantly higher than in H (c = 0.002) but similar to RA patients. CONCLUSIONS: Joint involvement of the wrist in SLE is similar to RA and is not as rare as expected, as shown by the comparison with healthy subjects. On the contrary, the involvement of the hand in SLE is significantly lower compared to RA.

Psoriatic arthritis (PsA) is a chronic inflammatory disease affecting peripheral and axial joints, usually associated with psoriasis (PsO) and involving various systems and organs (eye inflammation, such as uveitis; and involvement of nail and enthesis), and it usually requires a multidisciplinary treatment approach. Tumor necrosis factor-α (TNF-α) is overexpressed in psoriatic synovium and skin plaques and its selective inhibition by anti-TNF-α agents has been demonstrated to reduce TNF-α levels in the articular environment, reversing the synovial hyperproliferative phenotype. Studies performed on anti-TNF-α agents in PsA demonstrated that they are able to reduce neutrophil and macrophage infiltration as well as vascular cell adhesion protein 1 expression with ensuing synovial thickness normalization. The efficacy of anti-TNF-α agents for all PsA manifestations (peripheral arthritis, axial involvement, enthesopathy, and skin disease) suggests that anti-TNF-α efficacy might be related to the ability to influence angiogenesis and osteoclastogenesis, reduce synovial inflammation, and slow radiological disease progression. This review describes the role of anti-TNF-α in each manifestation of PsA.

OBJECTIVES: Tocilizumab (TCZ) is an effective treatment in patients with rheumatoid arthritis (RA) refractory to anti-tumour necrosis factor-α. However, only few studies in real life have evaluated the efficacy of TCZ in long-standing rheumatoid arthritis (LSRA). Our aim was to evaluate the efficacy and safety of tocilizumab in refractory LSRA. METHODS: Twenty-seven consecutive patients with refractory LSRA treated with at least one biologic agent were enrolled in a 19-month study in a single centre. Demographic [age, gender, disease duration, body mass index (BMI), previous therapies], clinical [total swollen and tender joints count (SJC-TJC) on 28, 44 and 68 joints, DAS28, Health Assessment Questionnaire (HAQ), infections, cardiovascular, renal, pulmonary and metabolic comorbidities], and serological [erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibodies] data were collected. Patients were evaluated at baseline, and after three and six months. RESULTS: Mean disease duration was 16.75±9.94 years. Seventeen out of 27 (62.9%) were RF positive and 13/27 (48.1%) were CCP positive. All of them experienced at least one previous biological agent (mean value 1.9±1.15; range 1-6). We observed a progressive reduction in all clinical and clinimetric features evaluated as well as a progressive reduction in steroids use. The EULAR response also improved. By analysing the RF positive subgroup we found that there is a better clinical response both at the 3rd and 6th month. CONCLUSIONS: TCZ is an effective and safe treatment in refractory LSRA.

INTRODUCTION: Psoriatic arthritis (PsA) is a rheumatic disorder that may be responsible for relevant articular impairment. The recently licensed Janus Kinase (JaK) inhibitors represent a new opportunity to improve PsA treatment. This review deals with the clinical usefulness of the selective JaK-1 inhibitor upadacitinib (UPA) in patients with PsA. COVERED AREAS: Two phase-III studies are available: SELECT-PsA 1, performed in patients with an inadequate response to non-biological therapies, and SELECT-PsA 2, conducted in biologic-experienced patients. Long-term extension results and post-hoc analysis data of these two trials are also available. EXPERT OPINION: The results provided by the trials indicate that UPA may be used to treat all of the clinical manifestations of PsA. Venous thromboembolism, cardiovascular events, and malignancy, the most feared adverse events associated with JaK inhibitor use, were not increased in the trial populations, yet long-term observational studies are needed to make sure that UPA is safe in this respect.

OBJECTIVE: To assess the findings of temporal artery colour duplex sonography (CDS) in GCA characterized by a histological pattern of periadventitial small vessel vasculitis (SVV) and/or vasa vasorum vasculitis (VVV) and compare it with those observed in classic GCA with transmural vasculitis. METHODS: We studied 30 patients with SVV and/or VVV, 63 patients with classic GCA and 67 biopsy-negative patients identified over a 9-year period. CDS of the temporal arteries was performed in all patients by one ultrasonographer. Temporal artery biopsy was used as the reference standard. Sensitivities, specificities and likelihood ratios (LRs) were calculated. RESULTS: The frequency of the halo sign on CDS was significantly lower in the patients with SVV and/or VVV compared with those with classic GCA (20% vs 82.5%, P = 0.0001). The halo sign had a sensitivity of only 20% (95% CI 8.4, 39.1%) and a specificity of 80.6% (95% CI 68.7, 88.9%) for the diagnosis of SVV and/or VVV. The negative LR was 0.992 (CI 0.824, 1.195), and the positive LR was 1.030 (CI 0.433, 2.451). The halo sign for the diagnosis of biopsy-proven classic GCA had a higher sensitivity of 82.5% (CI 70.5, 90.5%), the same specificity of 80.6% (CI 68.7, 88.9%) and a higher positive LR (4.253; CI 2.577, 7.021). CONCLUSION: The halo sign is infrequently found in GCA characterized by a histological pattern of SVV and/or VVV. This limits the sensitivity of CDS in correctly identifying patients with GCA.

BACKGROUND: Upadacitinib (UPA) is a selective JAK inhibitor recently approved for the treatment of psoriatic arthritis (PsA). In this post-approval study, we aimed to evaluate the effectiveness and safety of UPA over 24 weeks and identify clinical predictors of response, in a multicentric cohort of patients affected by PsA. METHODS: One hundred and twenty-six patients with PsA treated with UPA were enrolled in 10 Italian centres. UPA effectiveness outcomes, such as the proportion of patients with MDA status, DAPSA remission, and low disease activity, ASDAS-CRP inactive and low disease activity, and change from baseline in DAPSA and ASDAS-CRP scores, were evaluated every 12 weeks until week 24. The proportion of DAPSA minor, moderate, and major improvement, and ASDAS clinically important improvement (CII) and major improvement (MI) were considered as well. All treatment-related adverse events were collected during the observation period. Clinical predictors of MDA response at week 24 were evaluated through multivariate analysis. RESULTS: At baseline, 124/126 (98%) and 54/126 (43%) patients showed peripheral and axial involvement, respectively; 110 (87%) patients were intolerant or resistant to biologic DMARDs. At 24 weeks, MDA status, DAPSA remission, and ASDAS-CRP inactive disease were achieved in 47%, 23%, and 48% of patients, respectively. Minor, moderate, and major DAPSA improvement was observed in 67%, 39%, and 23%, respectively; while 65% and 35% achieved ASDAS-CRP CII and MI, respectively. The mean change from baseline was 15.9 ± 13.5 (p < 0.001) for DAPSA and 1.21 ± 0.97 (p < 0.001) for ASDAS-CRP. Thirteen patients (10%) discontinued UPA due to a lack of efficacy or non-serious adverse events. No serious adverse events were observed. Male gender (OR 2.54, 95% CI 1.03-6.25 p = 0.043), being naïve to biological DMARDs (OR 4.13, 95% CI 1.34-12.71, p = 0.013) and elevated baseline CRP (OR 2.49, 95% CI 1.02-6.12, p = 0.046) were associated with MDA response at week 24. CONCLUSIONS: This is one of the first real-life studies supporting the effectiveness of UPA and its safety profile in PsA patients. Furthermore, the study identifies predictors of MDA response to UPA treatment at 6 months.

OBJECTIVES: Ankylosing spondylitis (AS) is a chronic, progressive, and disabling disease, but the diagnosis is often missed and markedly delayed. An early diagnosis is important to establish a treatment to reduce disability and modify the natural course of disease. The aim of this study was to investigate the diagnostic (DD) and therapeutic (TD) delay according to the decade of diagnosis. The DD and TD correlation with radiological severity score and the new imaging techniques used in diagnosis (magnetic resonance [MRI], computerised tomography, scintigraphy for sacroiliac joints) were also investigated. METHODS: 135 AS patients (45 female and 90 male, 36.5±10.2 years old at diagnosis) with disease onset between 1950 and 2008, were investigated; the time from onset to diagnosis (DD) and treatment (TD), the New York and ASAS criteria fulfilment, the New York sacroiliac radiological score, bamboo spine presence at first visit and the new imaging technique used at diagnosis were recorded and their correlations were analysed. RESULTS: The New York and ASAS criteria were met at the first visit, by 87% and 96%, respectively. The delay from onset of symptoms to diagnosis and treatment was 9±8 and 12±11 years, respectively, but decreased significantly between different decades (p<0.001). The severity of sacroiliitis (mean 2±1; 17/135, 12.5% - IV grade sacroiliitis at diagnosis) and bamboo spine (3.7% at diagnosis) correlated with DD and TD (p<0.001). Sacroiliac MRI use at diagnosis significantly decreased both DD and TD (p>0.001 and p<0.05, respectively). CONCLUSIONS: DD and TD were correlated to radiological severity; they progressively decreased over 6 decades.

OBJECTIVES: The aims of our study were to investigate the prevalence of ultrasound (US) abnormalities in the foot of patients with rheumatoid arthritis (RA) and to compare them with the clinical findings. METHODS: One hundred RA patients were enrolled in the study. Bilateral US examination of metatarsophalangeal (MTP) joints, proximal interphalangeal (PIP) joints, midfoot joints (talonavicular, calcaneo-cuboid, medial, intermediate and lateral navicular-cuneiform and cuneiform-metatarsal joints and cuboid-4th and 5th metatarsal joints) were examined for synovitis and erosion. In addition the plantar fascia and the insertion of the anterior and posterior tibialis and peroneous brevis tendons were imaged. RESULTS: Effusion with synovial proliferation was visualised only at MTP joints in 84 out of 200 (42%) feet, at MTP plus at least one joint of the midfoot in other 41 out of 200 (20%) feet (making a total of 125 out of 200 (62%) MTP joints) exclusively in one or more joints of the midfoot in 7 out 200 (3%) feet, in the PIP joint of the 2nd and 3rd toes in 3 (1.5%) and 4 (2%) feet respectively, while no effusion with synovial proliferation was visualised in the PIP joint of the 4th and 5th toes. Synovitis was present most frequently in the 2nd MTP joint whilst erosions were most frequently imaged in the 5th MTP joint. CONCLUSIONS: US examination appears to be a useful imaging technique to study joint and tendon involvement of the foot in RA patients. Moreover, US examination of the foot is more sensitive than clinical examination in the detection of joint inflammation and allows for a better understanding of the features and the progression of the disease.

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.
RESUMEN
Dactylitis, one of the most typical features of psoriatic arthritis (PsA), is the diffuse swelling of the digits and is determined by the involvement of different anatomic structures, including: the subcutaneous fibrous tissue "accessory pulley" system; flexor tendons, with their related structures; the articular synovium; the small enthesis of the hands. Dactylitis is currently considered both a marker of disease activity and severe prognosis and its importance in PsA is emphasized by the inclusion in the classification criteria of PsA. This review focuses on the role of imaging in the management of PsA patients with dactylitis in clinical practice and in a research setting. Furthermore, imaging could be a valuable tool to assist in unravelling some of the underlying mechanisms of the onset and chronicization of dactylitis in PsA patients.
RESUMEN
The aims of our study were to investigate the prevalence of ultrasound (US) pathologic abnormalities and to compare them with the clinical findings in the knee of rheumatoid arthritis (RA) patients. One hundred RA patients were enrolled in the study. Bilateral US examination of the knee was performed to visualise the presence of effusion, synovial proliferation, bone erosions, femoral cartilage abnormalities, quadricipital and/or patellar enthesopathy. The popliteal fossa and the calf region were also evacuate to detect popliteal cyst. We observed joint effusion in 140 out of 200 (70%) knees. Synovial hypertrophy was present in 115 out of 140 (82%) knees associated with effusion and in 22 out of 115 (19%) knees intra-articular power Doppler (PD) signal was found. Hyperechoic spots within the cartilage layer, suggestive of pyrophosphate crystals deposit, were detected in the knees of 3 patients. US signs of quadricipital and/or patellar enthesopathy were detected in 53 out 200 (26%) knees. Bone erosions were visualised in 16 out 200 (8%) knees. Popliteal cyst was found in 66 out of 200 (33%) joints. US examination of the knee is more sensitive than clinical examination in the detection of joint inflammation and allows for the identification of different patterns of pathologic changes at knee level, including morphostructural changes at both cartilage and tendon level.

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 ≤ 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 ⢠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. ⢠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. ⢠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. ⢠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.
