Rheumatic diseases in migrant patients resident in Tuscany: epidemiological data analysis and single-center experience

OBJECTIVE

In the last decades, the number of foreigners in Tuscany has considerably increased with a multiethnic distribution. We reviewed the main rheumatic diseases in the foreign population resident in Tuscany and also reported the experience at the Rheumatology Division of the University Hospital of Careggi, Florence, in order to identify the areas of origin of these patients and the main rheumatic diseases observed in them.

METHODS

The collaboration with the Tuscan Region provided data about foreign patients residing in Tuscany on January 1, 2021 (country of origin, chronic diseases). Moreover, we conducted a retrospective review of the clinical charts of our Rheumatologic Division from January 1, 2019, to December 31, 2020.

RESULTS

In Tuscany, on January 1, 2021, there were 61,373 patients with chronic inflammatory rheumatic diseases, and 3994 of them (6.51%) were foreigners. Most patients were born in Europe (39.03%), followed by the Balkans (15%), South America (11.27%), and North Africa (10.31%). Inflammatory joint diseases, Sjögren syndrome, and systemic lupus erythematosus were the most frequent diseases. In the period 2019-2020, 511 foreign patients visited our Rheumatology Division and mainly originated from the Balkans (34.64%), South America (18%), and European countries (16.44%). In these patients, chronic inflammatory joint diseases and connective tissue diseases (systemic sclerosis, Sjögren syndrome, and systemic lupus erythematosus) were the most prevalent diseases.

CONCLUSIONS

This study provides a picture of the rheumatic diseases affecting foreign patients residing in Tuscany that are in agreement with the epidemiological data previously provided.

ToRaRI (Tofacitinib in Rheumatoid Arthritis a Real-Life experience in Italy): Effectiveness, safety profile of tofacitinib and concordance between patient-reported outcomes and physician's global assessment of disease activity in a retrospective study in Central-Italy

INTRODUCTION

The use of Janus Kinase Inhibitors (JAK-Is) in rheumatoid arthritis (RA) has entered in daily practice. In consideration of ORAL-Surveillance trial and the new EULAR recommendations, real-world data are needed to assess Jak-Is safety and effectiveness. The multicenter study presented here aimed to evaluate effectiveness and safety of tofacitinib in a real-life cohort.

METHODS

A retrospective analysis was performed from September 2021 to December 2022. Data were collected when tofacitinib was started (T0) and after 3 (T3), 6 (T6) and 12 (T12) months of treatment. The primary objective was to analyze the efficacy and safety of tofacitinib. Safety was assessed by recording adverse events (AEs) with and without discontinuation. The secondary objective was to assess the difference between Patient-Reported Outcomes (PROs) and Physician's Global Assessment of disease activity (PhGA).

RESULTS

122 patients were included in the study from the following rheumatology Centers: Pisa, Ancona, Florence (two Centers), Siena, and Sardinia. A statistically significant improvement in DAS-28-CRP, CDAI and SDAI score was observed at T3, T6, compared to baseline (p < 0.001). Improvement was confirmed in patients who reach T12. Patients naïve to bDMARDs showed a shorter remission time and higher remission rates. There was also a statistically significant improvement in PROs compared to baseline (p < 0.001). The improvement was rapid and was consistent with PhGA. The 12-month retention rate for tofacitinib was 89.35%. Reasons to stop tofacitinib were: insufficient response (7), gastrointestinal symptoms (2), infection (1), malignancy (1), Zoster (1), pruritus sine materia (1).

CONCLUSIONS

Tofacitinib is safe and effective in our RA cohort. It induces higher remission rates in patients naive to bDMARDs, suggesting that there may be a benefit using it as first-line therapy. Additionally, improvement in PROs was consistent with PhGA scores, demonstrating how tofacitinib affects both the objective and subjective components of disease activity. Key Points 1. JAK inhibitors are considered at a similar level as biologic agents in terms of effectiveness. 2. After ORAL-Surveillance results, real-world data are needed to assess the benefit/risk profile of Jaki. 3. Disagreement between patients and physicians has been previously reported with biologic therapy among patients with rheumatoid arthritis, with patients rating disease activity higher than physicians. 4. Jak inhibitors could reduce this discrepancy, due to their mechanism of action.

Efficacy and Safety of Upadacitinib in Rheumatoid Arthritis: Real-Life Experience from a Prospective Longitudinal Multicentric Study

BACKGROUND

We provide the first prospective longitudinal multicenter experience on Upadacitinib efficacy and safety profile in Rheumatoid Arthritis (RA) in a real-life context, focusing on clinimetric and ultrasonographic (US) data.

METHODS

RA patients referred to three Italian tertiary Centers who started Upadacitinib were enrolled as per ACR/EULAR classification criteria and prospectively reviewed. The primary aim of this study was to assess changes in clinimetric and ultrasonographic scores through time (at baseline, after 1 month, 3 months, and 6 months from the beginning of the therapy). Secondary aims were to: (i) estimate the impact of biologic lines of treatment and concomitant therapies on response to therapy; (ii) explore changes in laboratory parameters; and (iii) find potential predictive factors associated with response to therapy.

RESULTS

Seventy-one patients (49 Females and 22 Males) were included. Clinimetric scores, including the Disease Activity Score (DAS28-CRP) and Simplified Clinical Disease Activity Index (SDAI), and US findings (synovial hypertrophy and power Doppler) significantly improved (p = 0.029, p = 0.001, p = 0.001, p = 0.001, respectively). Regression analysis revealed a significant association between the concomitant csDMARDs therapy at baseline and the lack of improvement in synovial hypertrophy [OR -4.824, p = 0.010] as well as with DAS28-CRP [OR -0.690, p = 0.045], whereas the presence of increased ESR or CRP at baseline was able to predict a significant improvement in SDAI [OR 8.481, p = 0.003]. No adverse events, such as deep venous thrombosis, pulmonary embolism, or herpes zoster virus infection, were reported during this study observation.

CONCLUSION

Our real-life experience confirms the efficacy of Upadacitinib in terms of clinical and ultrasonographic improvement, as well as displaying a good safety profile.

Ultrasound evaluation of bowel vasculopathy in systemic sclerosis

BACKGROUND

Gastrointestinal (GI) manifestations are frequent in systemic sclerosis (SSc) with an impact on quality of life and morbidity. Bowel vasculopathy is a key pathogenetic factor responsible for GI involvement.

OBJECTIVES

To compare abdominal ultrasound (US) and Color Doppler Ultrasonography (CDU) features of splanchnic vessels of SSc patients with healthy controls.

METHODS

The charts of SSc patients who underwent an abdominal US and CDU study were retrospectively analyzed. For Superior Mesenteric Artery (SMA) and Inferior Mesenteric Artery (IMA) caliber, Peak Systolic Velocity (PSV), Reverse Velocity (RV), End-Diastolic Velocity (EDV), Mean Velocity (mV), Blood-flow, Resistive Index (RI) and Pulsatility Index (PI) were recorded.

RESULTS

28 SSc patients and 28 controls were enrolled. In SSc, caliber of SMA was significantly smaller than in controls (5.75 ± 0.62 mm vs. 6.45 ± 0.60 mm, p < 0.0001 - p adj =0.0002). The flow study of SMA and IMA showed a significant reduction of RV (SMA: 7.25 ± 6.37 cm/s vs. 18.52 ± 6.16 cm/s, p < 0.0001 - p adj <0.0001; IMA: 2.69 ± 6.10 cm/s vs. 17.06 ± 5.75 cm/s, p < 0.0001 - p adj <0.0001) and PI (SMA: 3.33 ± 0.75 vs. 4.53 ± 1.03, p < 0.0001 - p adj =0.0002; IMA: 3.54 ± 0.95 vs. 6.08 ± 1.53, p < 0.0001 - p adj <0.0001) in SSc patients than controls.

CONCLUSION

involvement of splanchnic vessels in SSc may be non-invasively investigated with abdominal US and CDU. Morphological and functional changes of Doppler parameters observed in SMA and IMA clearly demonstrate that these vessels are affected by SSc vasculopathy.

AB0747 Oral microbiome in rheumatic diseases.What involvement?

Background

The concept of core-microbiome in health is useful for investigating the possible role of the oral microbiome in autoimmune disease, such as Rheumatoid Arthritis, Spondyloarthritis, Sjogren Syndrome or Systemic Sclerosis (SSc), whose pathogenesis has not been fully understood. Environmental factors and certain genetic backgrounds have been proposed. Among the various environmental factors, the microbiota stands out, the entire composition of microorganisms, mainly bacteria but also fungi and viruses, which populate the human body.

Objectives

The aim of the study was to verify whether there were quantitative differences between the microorganisms present in the oral cavity, in particular between the lactobacillus spp., of patients with SSc compared to those present in the oral cavity of healthy subjects taken as controls.

Methods

Twenty-nine SSc female patients (mean age 62.) classified according to the ACR/EULAR2013 criteria and twenty-three female healthy subjects (HS, mean age 57.6) were enrolled and underwent tongue and gum swab sampling. Quantitative PCR was conducted in triplicates using Lactobacillus specific primers rpoB1, rpoB1o and rpoB2 for RNA-polymerase β subunit gene.

Results

Our data showed Lactobacillusspp.rpoB sequences significantly lower in the tongue of SSc patients than in HS (p=0.0211).The statistical analysis in HS highlighted a significant lower amount of rpoB on the gums than on the tongue.

Conclusion

Our preliminary data show that the number of Lactobacillus on the tongue in SSc patients is about half that of HS. These data make it more likely that Lactobacillus in SSc patients may play a protective role. Further investigations will also be needed in other autoimmune diseases.

Combination of denosumab and biologic DMARDs in inflammatory muscle-skeletal diseases and connective tissue diseases

OBJECTIVE

Osteoporosis (OP) can complicate the course of rheumatic musculoskeletal diseases (RMDs) and connective tissue diseases (CTDs). Denosumab, a monoclonal antibody against RANK-L, showed beneficial effect in rheumatoid arthritis in inhibiting radiographic progression and erosive burden. We tested the efficacy, safety, and persistence on the treatment of the combination of biologic disease-modifying antirheumatic drugs (bDMARDs)/denosumab versus bDMARD in patients with RMD and CTD.

METHODS

This is a retrospective evaluation of a single center, including patients with RMD/CTD (including rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, systemic sclerosis, and overlap syndromes) treatment with bDMARD/denosumab, compared to age, gender, disease, bDMARD, and conventional synthetic disease-modifying antirheumatic drugs-matched controls.

RESULTS

Twenty-eight bDMARD/denosumab patients and 49 bDMARD patients were eligible. Despite a statistically significant difference during the first-year efficacy (due to the different baseline timepoint), there was no difference in the efficacy profile in the second year of treatment and in the safety profile (including local, systemic, and serious adverse events). Moreover, no statistically significant difference in the persistence of bDMARD treatment over 2 years of evaluation was found. The combination of bDMARD and denosumab was not an independent predictor of disease flare or bDMARD treatment withdrawal.

CONCLUSION

The combination of bDMARD and denosumab does not alter the efficacy and the safety profile of the bDMARD in patients with RMD/CTD. Future studies verifying the radiological disease inhibition could support denosumab use in RMD/CTD other than rheumatoid arthritis, when complicated by OP.

Idiopathic inflammatory myopathies: one year in review 2021

Idiopathic inflammatory myopathies (IIMs) are a heterogeneous group of rare and complex connective tissue diseases, mainly characterised by inflammatory involvement of skeletal muscles. Several other organs may be affected, particularly lungs, heart, skin, gastrointestinal tract and joints, often determining the morbidity and mortality associated with these autoimmune disorders. The course is generally chronic and the onset subacute. This latter aspect, together with the rarity of these conditions, can result in a clinical challenge for the physician with a considerable diagnostic delay. The scientific literature makes continuous advances in the understanding of these diseases, in particular with regards to the pathogenesis, serological findings, diagnostic strategies and therapeutic approaches. The aim of this review is to highlight the most relevant literature contributions published on this topic over the last year.

Switching from originator adalimumab to biosimilar SB5 in a rheumatology cohort: persistence on treatment, predictors of drug interruption and safety analysis

Aims:

Medical and non-medical switching strategies have been adopted in Europe in the last few years. We aimed to investigate persistence on treatment with a SB5 Adalimumab (SB5) biosimilar after switching from Adalimumab (ADA) originator among patients with inflammatory rheumatic musculoskeletal diseases (iRMD), identifying possible predictors of drug interruption and describing adverse events.

Method:

iRMD patients previously switched to SB5 after at least 6 months of ADA were enrolled. Data on concomitant medications, disease flares, and persistence on SB5 up to the last available follow up were collected retrospectively. Kaplan–Meier and Cox regression models were used.

Result:

A total of 172 patients (106 females, ADA duration 5.8 ± 3.8 years) were enrolled, including 34 rheumatoid arthritis, 59 psoriatic arthritis, and 61 axial spondyloarthritis patients. In a 10 ± 3 months follow up, 65 (37.8%) patients presented with adverse events, with 46 (26.7%) showing a clinically defined disease flare (no disease activity and patient reported outcomes assessment were available); 24 patients interrupted SB5 permanently (among them, 11 back-switched to ADA and 8 were prescribed a different biological therapy). Probability of persistence on SB5 was 94.7% at 6 months and 85.1% at 12 months. Baseline corticosteroid [hazard ratio (HR) 3.209, 95% confidence interval (CI) 1.193–8.635, p = 0.021] and therapy with nonsteroidal anti-inflammatory drugs (NSAIDs) (HR 2.876, 95% CI 1.229–6.727, p = 0.015), as well as the baseline corticosteroid dose (HR 1.200, 95%CI 1.026–1.403, p = 0.022) were predictors of drug interruption.

Conclusion:

Our data on persistence of treatment and adverse events are in line with previous reports. Further large cohort studies may confirm baseline corticosteroid and NSAIDs use as predictors of SB5 interruption, helping to identify patients at higher risk of failure after switching.

Oral Lactobacillus Species in Systemic Sclerosis

In systemic sclerosis (SSc), the gastrointestinal tract (GIT) plays a central role in the patient's quality of life. The microbiome populates the GIT, where a relationship between the Lactobacillus and gastrointestinal motility has been suggested. In this study, the analysis of oral Lactobacillus species in SSc patients and healthy subjects using culture-independent molecular techniques, together with a review of the literature on microbiota and lactobacilli in SSc, has been carried out. Twenty-nine SSc female patients (mean age 62) and twenty-three female healthy subjects (HS, mean age 57.6) were enrolled and underwent tongue and gum swab sampling. Quantitative PCR was conducted in triplicate using Lactobacillus specific primers rpoB1, rpoB1o and rpoB2 for the RNA-polymerase β subunit gene. Our data show significantly (p = 0.0211) lower LactobacillusspprpoB sequences on the tongue of patients with SSc compared to HS. The mean value of the amount of Lactobacillus ssprpoB gene on the gumsofSSc patients was minor compared to HS. A significant difference between tongue and gums (p = 0.0421) was found in HS but not in SSc patients. In conclusion, our results show a lower presence of Lactobacillus in the oral cavity of SSc patients. This strengthens the hypothesis that Lactobacillus may have both a protective and therapeutic role in SSc patients.

AB0256 BARICITINIB (BARI) VERSUS BIOLOGICS IMPACT ON STEROID TAPERING IN RHEUMATOID ARTHRITIS (RA)

Background:

Biologic and target synthetic disease modifying anti-rheumatic drugs (bDMARDs and tcDMARDs) are recommended to control RA disease activity, pain and steroid use. Following randomized clinical trials (RCTs) and their post-hoc analyses, the Janus Kinase Inhibitor tsDMARDs BARI was superior to reference bDMARD Adalimumab in reducing disease activity, pain and functional disability. In addition, BARI monotherapy also determined more significant pain reduction and functional improvement when compared to Tocilizumab monotherapy (3).

Objectives:

to confirm RCT results in a real-life clinical setting, with focus on disease activity, pain, functional disability and steroid tapering, when comparing BARI to bDMARDs for the treatment of active RA.

Methods:

RA patients starting BARI or a bDMARD for active RA were retrospectively evaluated from June 2019 to June 2020. Disease activity (DAS28CRP, SDAI, CDAI), pain visual analogic scale (pain_VAS), functional disability (HAQ) assessments and mean prednisone dosage (pred_dose) were collected at baseline (BL), 3 months (3M) and 6 months (6M) after BARI/bDMARD initiation. The changes of the outcome measures were evaluated between BL-3M, 3M-6M and BL-6M, as well as between BARI and bDMARDs groups. Finally, we assessed the variables associated with prednisone tapering in the whole population.

Results:

90 out of 100 RA patients evaluated (baseline: age 57±12 years, disease duration 131±100 months, DAS28PCR 4.8±1.0, pain_VAS 61±23 mm, prednisone dose 5.5±5.3 mg) were eligible for the study; 49 received BARI and 41 bDMARDs (17 abatacept, 12 TNF inhibitors, 11 tocilizumab, 1 rituximab). At BL, the two groups did not differ statistically in terms of age, sex, disease duration, disease activity, pain_VAS, previous bDMARD failure or ts/bDMARD naive, concomitant conventional synthetic DMARDs treatment, pred_dose. Both BARI and bDMARDs determined a significant reduction in activity scales and HAQ when comparing BL-3M and BL-6M, with only pain_VAS and pred_dose showing a significant decrease in the 3M-6M interval. When comparing the two groups, BARI showed a significantly higher reduction of pred_dose (-3.2±5.1 vs -1.7±3.7 mg at BL-3M, and -4.1±5.3 vs -1.9±4.6 mg at BL-6M), which was not significant after adjusting for BL pred_dose. No other difference was seen when the two groups, including the numerically higher reduction of pain_VAS in the BARI group (-29±28 vs -20±27 mm at BL-3M and -35±25 vs -30±28 mm at BL-6M comparison). The analysis of the predictors for steroid tapering (Δmean_pred) in the two intervals, showed that BL DAS28PCR, DAS28PCR BL-3M change and BL pred_dose were associated with BL-3M Δmean_pred, while 3M pain_VAS and 3M pred_dose were associated with 3M-6M Δmean_pred.

Conclusion:

Although limited by the small samples and the retrospective nature, our real-life comparison shows similar efficacy of BARI and bDMARDs in terms of disease activity control, functional disability and pain. In addition, the treatment with BARI or bDMARD did not influence the steroid tapering, which was driven mostly by its initial dose, disease activity and pain. Larger real-life multi-center studies are warranted to confirm our results.

POS1495-HPR THE EXPERIENCE OF A RHEUMATOLOGY UNIT DURING THE COVID19 LOCKDOWN: TELEMEDICINE ALLOWS A SAFE FOLLOW UP OF PATIENTS WITH RHEUMATIC DISEASES

Background:

In March this year, most of the routine activities were cancelled during the streaming of the pandemic in Italy. This prompted a pragmatic reorganization of the traditional care model of nursing and medicine, to quickly give an efficient clinical response. During the first phase of the pandemic, outpatient visits dropped by more than 60%, forcefully shifting to telemedicine to assure continuity of care despite the lockdown.

Objectives:

The aim of the present work was to describe the strategy adopted during and immediately after the lockdown to assure the follow up of patients and the maintenance of their treatment in an outpatient “virtual” telemedicine clinic dedicated to RDs.

Methods:

the patient flow to a rheumatology division during the lockdown was evaluated retrospectively from March to September 2020 in accordance with local restrictions, and three periods are described.

Results:

653/913 (71.5%), 542/542 (100%) and 1.048/1.048 (100%) infusion activities scheduled were performed at the centre for daily infusion and pre-infusion assessment, respectively during the 1st, 2nd and 3rd period. In the outpatient clinic during the 1st period, 96.96% of the cases was shifted to Telemedicine, which decreased to 52.45% in the 2nd period; while in the 3rd period, 97.6% of the performances were carried out at the clinic. Diagnostic procedures, such as ultrasound, capillaroscopy, and joint injection were generally postponed during the 1st period, reduced drastically during the 2nd and performed regularly during 3rd period. Ulcer treatment and the Clinical Trial Unit never stopped their activity. The flow of the activity of the outpatient clinic and the day hospital is represented as monthly trends in graph 1 (See Graph 1).

Conclusion:

Our data show the feasibility of Telemedicine in a lockdown condition. Shifting stable patients to Telemedicine has the potentiality to minimize the risk of contagion and allow continuity of care. In the future, the use of Telemedicine for specific clinical uses might assure patient assistance also in non-pandemic conditions.

OP0176 ULTRASOUND (US) EVALUATION OF BOWEL VASCULOPATHY IN SYSTEMIC SCLEROSIS (SSC)

Background:

Gastrointestinal involvement is one of the most frequent features of SSc, affecting nearly 90% of patients, with a great impact on quality of life and morbidity. One of the key pathological factors of SSc bowel involvement is vasculopathy (1), although little is known about its pathophysiology and no treatments are currently available.

Objectives:

to assess with abdominal US the superior mesenteric artery (SMA) and the inferior mesenteric artery (IMA) vessel characteristics and blood flow in SSc, compared to healthy controls (HC).

Methods:

we performed fasting abdominal US in SSc patients fulfilling the ACR/EULAR 2013 classification criteria and HC. Patients with a history of peripheral /coronary arterial disease were excluded. For both SMA and IMA, caliber (mm), Peak Systolic Velocity – PSV (cm/sec), Reverse Velocity – RV (cm/sec), End-Diastolic Velocity – EDV (cm/sec), Mean Velocity – mV (cm/sec), Blood-flow (cm/sec), Resistive Index – RI and Pulsatility Index – PI were measured.

Results:

28 SSc patients [25 females (89.3%), mean age 48.75 ± 12.39 years; 6 (22.22%) anti-centromere and 19 (70.37%) positive for anti-topoisomerase I antibodies] and 28 HC [18 females (64.3%), mean age 36.25 ± 12.08 years] were evaluated. In SSc, the SMA caliber was significantly smaller than in HC (5.75 ± 0.62 vs. 6.45 ± 0.60 mm, p<0.0001), while IMA dimensions did not differ.

The SMA study revealed SSc patients had a significant reduction of RV (7.25 ± 6.37 vs. 18.52 ± 6.16 cm/sec, p<0.0001) and PI (3.33 ± 0.75 vs. 4.53 ± 1.03, p<0.0001) when compared to HC. In addition, in SSc the mV of SMA was significantly lower than in HC (38.03 ± 13.90 vs. 28.32 ±9.25 cm/sec, p=0.0035), as well as the RI (0.88 ± 0.04 vs. 0.91 ± 0.03, p=0.0034); EDV was significantly increased (16.34 ± 7.03 vs. 12.64 ± 5.46 cm/sec, p=0.0321). Similarly to SMA, also in IMA RV and PI were significantly lower that controls (RV: 2.69 ± 6.10 vs. 17.06 ± 5.75 cm/sec, p<0.0001; PI: 3.54 ± 0.95 vs. 6.08 ± 1.53, p<0.0001). Moreover SSc patients presented a significant reduction of PSV and RI of IMA (PSV: 72.27 ± 27.23 vs. 93.81 ± 25.73 cm/sec, p=0.0084; RI: 0.88 ± 0.04 vs. 0.91 ± 0.03, p=0.0132) when compared to HC. Although the HC group was significantly younger than the SSc group (p=0.0003), all the results were confirmed after adjustment for age (Table 1).

Conclusion:

this preliminary study shows, for the first time, the presence of a significant reduction of RV, PI and RI in the intestinal arteries of SSc patients when compared to HC. These data show an increased stiffness of the gastrointestinal arterial wall, in agreement with the typical SSc vasculopathy. A larger cohort is needed to confirm the results and explore the possible relationship with other clinical features of the disease.

Baricitinib in the treatment of rheumatoid arthritis: clinical and ultrasound evaluation of a real-life single-centre experience

Background:

Ultrasound (US) is useful in monitoring RA patients, with the US7 score allowing grey-scale and power-Doppler (PD) semi-quantitative evaluation of synovitis and teno-synovitis. We evaluated real-life efficacy and safety of Baricitinib, an oral selective JAK1-2 inhibitor, in RA patients using clinical, clinimetric, and US assessments.

Methods:

Disease activity score in 28 joints calculated with C-reactive protein (DAS28-CRP), disease activity score in 28 joints calculated with erythrocyte sedimentation rate (DAS28-ESR), clinical disease activity index (CDAI), simplified disease activity index (SDAI), visual analogue scale (VAS)-pain, health assessment questionnaire (HAQ), COCHIN scale, adverse events (AE), concomitant medications, laboratory parameters, and US7 were performed/recorded at baseline, 1, 3, and 6 months in RA patients starting Baricitinib. Responder/non-responder status was determined according to the EULAR Response Criteria at 3 months. SDAI clinical remission or low disease activity (LDA) were calculated at 3 and 6 months.

Results:

In 43 enrolled patients, a significant improvement in disease activity and US7 components (except tendon PD) and a reduction of steroid dosage were observed. Responders at 3 months showed a significantly higher reduction of CDAI, SDAI, COCHIN scale, VAS-pain, and US7 synovialPD, compared with non-responders. At 3 and 6 months, remission/LDA was achieved by 12.8/53.8% and 21.6/51.3% patients, respectively. The csDMARD co-treatment was independently associated with remission/LDA at 3 months. Safety-related drop-outs were in line with literature data. The steroid dosage was associated with AE development at 6 months.

Conclusion:

The real-life data, also obtained with US evaluation, confirmed the Baricitinib efficacy in RA disease control, as well as the utility of assessment during the follow up of disease activity.

Prediction and primary prevention of major vascular complications in systemic sclerosis

OBJECTIVE

In Systemic Sclerosis (SSc), vasculopathy is the background of major vascular complications (MVCs), like digital ulcers (DUs), pulmonary arterial hypertension (PAH) and scleroderma renal crisis (SRC). We aimed to identify the predictors and to test the primary preventive effect of vasoactive/vasodilating drugs (VVD) for the development of MVCs in SSc MVCs-naïve patients.

METHODS

patients fulfilling the ACR/EULAR 2013 classification criteria for SSc without history of MVCs were eligible. Data about clinical manifestations, laboratory and instrumental assessments and treatments were retrospectively collected at baseline and latest available follow-up.

RESULTS

134 SSc patients were enrolled (mean age 56.5 years ± 14.2, females 88.1%, limited subset 61.9%, ACA positivity 60.4%). In a mean of 43 ± 19 months of follow-up 12 (9.0%) patients developed at least 1 MVC (10 DU, 2 PAH and 1 SRC). Dyspnoea and arthritis at baseline were independent predictors for MVCs development (p = 0.012, and p = 0.002 respectively). No primary preventive effect of VVD on MVCs development was found. However, sildenafil reduced the renal resistive index increase (p = 0.042) and alprostadil slowed the DLco decline (p = 0.029). Both iloprost and angiotensin-receptor blockers (ARBs) delayed MVCs development, while angiotensin converting enzyme inhibitors (ACEi) determined an earlier onset of such MCVs.

CONCLUSIONS

in SSc patients, our data confirm the role of arthritis and dyspnea as independent predictors of major vascular complications, in particular in MVCs-naïve patients. Prostanoids, sildenafil and ARBs, even in absence of a primary preventive action, might help in slowing disease progression and postponing the onset of MVCs.

Risk of Malignancy and Biologic Therapy in Rheumatic Inflammatory Diseases: A Single-center Experience

OBJECTIVES

Biologic disease modifying anti-rheumatic drugs (bDMARDs) have significantly improved the care of patients with rheumatic muscle-skeletal disorders (RMDs). Considering their immunosuppressive action, a theoretical increase of malignancy risk has been a major concern in the last few decades. The objective of this study is to analyze the incidence of malignancies in a cohort of patients affected by rheumatoid arthritis (RA), psoriathic arthritis (PsA), and ankylosing spondylitis (AS) treated with bDMARDs.

METHODS

The charts of bDMARD-treated RMD patients were reviewed, and data about bDMARD exposure and malignant cancers (excluding non-melanoma skin cancer) were collected.

RESULTS

921 patients were included (median age: 50.59 years, 66.67% females); 1374 bDMARD treatments were administered, 87.12% were tumor necrosis factor inhibitors. A total of 21 malignant neoplasms were detected in 21 patients (61.90% females, median age at cancer diagnosis: 64.99 years), 66.67% in RA patients, 19.05% in PsA, and 14.28% in AS. Among them, 10 patients (47.62%) were treated with etanercept, 6 patients (28.57%) with adalimumab, and 1 case each with tocilizumab, certolizumab, golimumab, infliximab, and abatacept. The most common malignancies that we found were lung cancers, ductal mammary carcinomas, melanomas, and lymphomas. The incidence rate (IR) of malignancies in our cohort was 3.47 per 1000 person-years (p-y); the higher IRs were in RA patients (5.13 per 1000 p-y), in males (4.21 per 1000 p-y), and in patients aged >70 years (10.14 per 1000 p-y).

CONCLUSIONS

The results of our study showed IR of malignancies in RMD patients treated with bDMARDs that is in agreement with literature data.

The switch from etanercept originator to SB4: data from a real-life experience on tolerability and persistence on treatment in joint inflammatory diseases

Aims:

Switching from originator to biosimilar is part of current practice in inflammatory rheumatic musculoskeletal diseases (iRMDs) such as rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondylarthritis (axSpA), with evidences derived from both etanercept (ETN) to SB4-switching randomized controlled trials and real-life registries. We investigated the safety and treatment persistence of ETN/SB4 in a multi-iRMD cohort derived from two rheumatology departments in our region.

Methods:

Adult patients with iRMDs, treated with ETN for at least 6 months and switched to SB4 in stable clinical condition, were eligible for this retrospective evaluation. Retrospective data on adverse events, loss of efficacy and persistence on treatment were collected until latest available follow-up.

Results:

A total of 220 patients (85 RA, 81 PsA, 33 axSpA, 14 juvenile idiopathic arthritis and seven other conditions; 142 females, mean age 58 ± 7 years, disease duration 12 ± 4 years, ETN duration 7 ± 4 years) were enrolled, with median follow-up of 12.1 (9.7–15.8) months. A total of 50 patients (22.7%) presented with at least one adverse event, with 36 (16.4%) disease flares and 30 (13.6%: 11 for safety and 19 loss of efficacy) SB4 withdrawals. Cumulative SB4 treatment persistence was 99.1%, 88.6% and 64.6% at 6, 12 and 18 months respectively. Back-switch to ETN was performed in 17/30 cases, the remaining cases were managed with change of biologic disease modifying or conventional synthetic anti-rheumatic drug. Age was the only significant predictor of SB4 interruption at 6 months.

Conclusion:

Our real-life data confirm the safety profile of switching from ETN to SB4, with slightly higher treatment persistence rates compared with other real-life registries.

The systemic sclerosis patient in the COVID-19 era: the challenging crossroad between immunosuppression, differential diagnosis and long-term psychological distress

COVID-19 is a world health emergency which may inevitably affect the management of a complex autoimmune disease such as systemic sclerosis (SSc). Several SSc patients are frail and, in this pandemic, need a careful protection. The COVID-19 infection might complicate the clinical scenario of interstitial lung disease (ILD) in SSc because it determines a severe pneumonia characterized by radiological features similar to SSc-ILD. The striking CT similarities between the 2 diseases make it difficult to distinguish a worsening of SSc-ILD from COVID-19-ILD superinfection. Moreover, other aspects, like isolation during lock down, may cause a significant psychological stress which will pile up on the already difficult contact with the patients for a routine check-up. Moreover, the drug shortage is a real problem in these times. For these reasons, the rheumatologist in daily clinical practice should carefully differentiate the possible COVID-19 infection in order to optimize the patient management. Therefore, the challenge in everyday life will be to achieve in due time the differential diagnosis as well as the long-term psychological impact.Key Points• SSc patients should be encouraged to continue their chronic therapy; in case of immunosuppressive therapy it must be discontinued for safety in case of COVID-19 infection.• Psychological support must be guaranteed to every SSc patients.• COVID-19 pneuminia is hard to distinguish from an interstitial lung disease due to SSc lung involvment.• Data sharing is fundamental for an optimal managment of SSc patients during COVID-19 pandemia.

AB0281 SAFETY AND RETENTION RATE AFTER SWITCHING FROM ETANERCEPT ORIGINATOR (ETN) TO ETANERCEPT BIOSIMILAR (SB4) IN INFLAMMATORY JOINT DISEASES: DATA FROM REAL LIFE

Background:

SB4 in now commonly used in the treatment of inflammatory joint diseases, with evidence of efficacy and persistence up to 12 months from switching in both randomized controlled trials in Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA) and Ankylosing Spondylitis (AS).

Objectives:

we investigated the safety and retention rate of SB4 at 6, 12 and 18 months after switching from ETN in two rheumatology departments in our region.

Methods:

adult patients with RA, PsA, AS, Juvenile Idiopathic Arthritis (JIA) and other rheumatic diseases treated with ETN for at least 6 months, switched to SB4 in stable clinical conditions, were eligible for this retrospective evaluation. Data on adverse events (in particular infectious events), loss of efficacy (articular, cutaneous, ocular or intestinal disease re-activation) and persistence on treatment were collected since latest available follow-up. Retention rate, reason for discontinuation and subsequent management data were collected at 6, 12, 18 months.

Results:

220 patients (142 females, mean age 58+-7 years, disease duration 12+-4 years, ETN duration 7+-4 years) were enrolled, with median follow up of 12.1 (9.7-15.8) months duration; ETN was used in different biologic DMARDs treatment lines (first 76.8%, second 17.7%, third 3.2 %, fourth 2.3%). Study population was composed of 85 RA, 81 PsA, 33 AS, 14 JIA and 7 other conditions (mostly scleroderma). In the follow-up, 50 patients (22.7%) presented with at least one non-serious adverse event, with 36 (16,4%) disease re-activation (mostly articular) and 30 (13,6% - 11 for safety and 19 loss of efficacy) SB4 interruptions. Retention rates were 99.1 (210/212) at 6, 90.9% (150/165) at 12 and 81.5% (53/65) at 18 months respectively. Back-switch to ETN was performed in 17/30 cases, the remaining cases were managed with change of bDMARD or csDMARD). Age was the only significant predictor of SB4 interruption at 6 months (OR 1.058, 95%CI 1.007-1.112, p=0.026), while disease, bDMARD line, csDMARD combination, gender, disease duration or ETN duration did not influence retention rates at 6, 12 or 18 months.

Conclusion:

our real-life data confirm the safety profile of switching from ETN to SB4. In our patients, the data show a higher retention rate, when compared to other-real life registries data (1,2)

AB0239 EFFECTS OF DYSMETABOLISMS AND COMORBIDITIES ON THE EFFICACY, SAFETY AND RETENTION RATE OF BIOLOGICAL DMARDS (bDMARD) IN INFLAMMATORY JOINT DISEASES

Background:

bDMARDs have an effect on glucose homeostasis (1), lipoproteins profile (2; 3) and blood pressure (4). However, with the exception of obesity (5; 6), there are no clear data on how bDMARDs work in patients who already have or develop metabolic comorbidities and whether these conditions can impact on their efficacy and safety profile.

Objectives:

to evaluate, in chronic inflammatory joint diseases, the effect of arterial hypertension (AH), dyslipidemia (DYS) and diabetes mellitus (DM) on efficacy, safety and retention rate of first-line bDMARDs therapy.

Methods:

a retrospective observational study on the clinical charts of Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA) or Ankylosing Spondylitis (AS), treated with first on-label bDMARD was performed. Data on adverse events, efficacy and comorbidities at the baseline visit in which the bDMARD was prescribed (BL), the visit performed after 6 months of therapy (6M), and the last visit on treatment (LoT) were collected.

Results:

383 patients (41,8% RA, 33,4% PsA and 24,8% AS) were included in the study, with the predominance of females (F: 67,36%, M: 32,64%; mean age 51,67 ± 15,11 years). Our data show that the presence of comorbidities had no influence on efficacy of bDMARD, while patients who had DYS at BL manifested a higher rate of systemic adverse events either in the first 6 months of therapy (58,9% vs 43,7%, p=0,040) and also later on (80,36% vs. 66,67%, p=0,046). In addition, patients who developed DYS and AH after the 6M visit reported a higher rate of systemic adverse events at LoT visit, compared to others (DYS: 97,8% vs 66,7%, p<0,001; AH: 86,9% vs 65,2%, p=0,031). For what concerns the retention rate, patients who developed DYS or AH during bDMARD treatment continued the drug for a longer period of time (DYS 95,5 vs 19,6 months, p<0,001; AH 72,1 vs 23,4 months, p<0,001). In particular, patients with AH who concomitantly carried out therapy with ACE-inhibitors (ACEi) and/or angiotensin II receptor blockers (ARB) continued bDMARDs for nearly 20 more months than patients who were not exposed to these drugs (40,5 vs 23,4 months, p=0,001) and more frequently maintained the bDMARDS at LoT (59,42% vs. 47,53%). In case of withdrawal in the ACEi/ARB exposed cohort, this was due to well-being and disease remission rather than inefficacy or adverse reaction (p=0,025). In dyslipidemic patients treated with statins, data showed that bDMARDs were continued for a longer time than in DYS patients treated with other anti dyslipidemic therapies (41,09 vs. 26,50 months, p=0,042).

Conclusion:

our data suggest that AH and DYS may be associated with higher frequency of adverse events but a better drug retention. The combination of bDMARD and ACEi/ARB may determine a better control of the inflammatory process by inhibition of angiotensin II, favouring the achievement of remission. In AH patients on bDMARDs, ACEi and ARB could therefore represent an useful anti-hypertensive drug choice. Similarly, statins could be the treatment of choice in DYS patients.

AB0361 EFFICACY AND SAFETY OF BARICITINIB (BARI) IN RHEUMATOID ARTHRITIS(RA): CLINICAL AND ULTRASOUND EVALUATION IN REAL LIFE

Background:

Remission or low disease activity (LDA) are the ultimate goals of both conventional synthetic (csDMARD), target synthetic and biologic disease-modifying anti-rheumatic drugs (bDMARD) in treating RA. Janus Kinase (JAK) inhibitors are nowadays part of tsDMARDs, with BARI as an oral selective JAK1-2 inhibitor. Ultrasound (US) is a valuable imaging tool for detecting inflammatory joint changes and monitoring RA patients. The US7 score (US7) is a semiquantitative score including grayscale (GS) and power Doppler (PD) measurements of synovitis and tenosynovitis in 7 joints of the clinically dominant hand and foot.

Objectives:

to evaluate real life efficacy and safety of BARI 4 mg in RA patients using clinical, clinimetric and US evaluation.

Methods:

adult RA patients starting BARI were eligible. DAS28ESR, CDAI, SDAI, painVAS, HAQ, COCHIN, laboratory parameters and US7 were performed/collected at baseline (BL) and after 3 and 6 months. Adverse events (AE) and concomitant medications were recorded. Responder/non responder status was determined using DAS28ESR improvement according to the EULAR Response Criteria at 3 months. Moreover, SDAI clinical remission or LDA (remission: SDAI≤3,3; LDA:3,3<SDAI≤11) were calculated at 3 and 6 months.

Results:

43 patients (12 csDMARD and 31 bDMARD failure) were enrolled, with 30 patients starting BARI in combination with a csDMARDs. BL painVAS was 68±23mm and disease activity was moderate to severe according to DAS28VES, CDAI and SDAI. BARI determined a significant improvement of every disease activity composite score and US7 components, except tendon PD; steroid daily dosage was significantly reduced.

28 patients were considered Responders at 3 months: responders used to have higher disease activity levels and synovitis scores at baseline.

Interestingly, painVAS and steroid dosage significantly decreased both in responders and non-responders, achieving similar value at 6 months. Non-responders showed both synovial and tendon involvement relapse at 6 months, with significantly higher PD score compared to responders. Remission was reached by 12,8% patients at 3 months and 21,6% at 6 months, while LDA patients were respectively 53,8% and 51,3%; combination with csDMARD was the only factor positively associated with remission/LDA at 3 months.

The percentage of dropped-out patients due to AE was aligned with literature data (5% in 6 months) whereas the percentage of Herpes Zoster Virus (HZV) infections was higher (4,6% in 6 months in our population vs 4,3% in 1 year in RCTs). Corticosteroid dosage was directly associated with AE development at 6 months.

Conclusion:

Real life data confirmed BARI RCTs efficacy and safety data. Non responders showed both synovial and tendon PD disease relapse, despite painVAS and steroid reduction were comparable to responders. In our population, HZV infection prevalence was higher than in RCTs and corticosteroid dosage was positively associated with AE development at 6 months.

Effect of Dysmetabolisms and Comorbidities on the Efficacy and Safety of Biological Therapy in Chronic Inflammatory Joint Diseases

In the present study we evaluated how systemic arterial hypertension (SAH), dyslipidemia and diabetes mellitus influence the efficacy, safety and retention rate of biological disease-modifying anti-rheumatic drug (bDMARD) treatment in rheumatic musculoskeletal disorders (RMDs). The charts of RMD patients treated with the first-line bDMARD were reviewed, collecting data on safety, efficacy and comorbidities at prescription (baseline, BL), after 6 months (6M) and at last observation on bDMARD (last observation time, LoT). In 383 RMD patients, a higher rate of adverse events at 6M (p = 0.0402) and at LoT (p = 0.0462) was present in dyslipidemic patients. Patients who developed dyslipidemia or SAH during bDMARD treatment had similar results (dyslipidemia p = 0.0007; SAH p = 0.0319) with a longer bDMARD retention as well (dyslipidemia p < 0.0001; SAH p < 0.0001). SAH patients on angiotensin converting enzyme inhibitors (ACEis) or angiotensin-II receptor blockers (ARBs) continued bDMARDs for longer than non-exposed patients (p = 0.001), with higher frequency of drug interruption for long-standing remission rather than inefficacy or adverse reactions (p = 0.0258). Similarly, dyslipidemic patients on statins had a better bDMARD retention than not-exposed patients (p = 0.0420). In conclusion, SAH and dyslipidemia may be associated with higher frequency of adverse events but a better drug retention of first-line bDMARD in RMDs, suggesting an additional effect of ACEis/ARBs or statins on the inflammatory process and supporting their use in RMD bDMARD patients with SAH/dyslipidemia.

One year in review 2019: idiopathic inflammatory myopathies

The idiopathic inflammatory myopathies (IIMs) are a rare group of immune, systemic diseases characterised by muscle inflammation and frequently by extramuscular involvement. IIMs are heterogeneous with generally a chronic or subacute onset, which vary from less severe to more serious manifestations, not always easy to diagnose and even less to manage. In the past year, many studies have been published in order to clarify disease pathogenesis and improve patient management and treatment.The purpose of this review article is to provide an overview of the new insights in pathogenesis, serological findings, clinical manifestations and treatment of IIMs, summarising the most relevant studies published over the last year.

Classification, categorization and essential items for digital ulcer evaluation in systemic sclerosis: a DeSScipher/European Scleroderma Trials and Research group (EUSTAR) survey

BACKGROUND

A consensus on digital ulcer (DU) definition in systemic sclerosis (SSc) has been recently reached (Suliman et al., J Scleroderma Relat Disord 2:115-20, 2017), while for their evaluation, classification and categorisation, it is still missing. The aims of this study were to identify a set of essential items for digital ulcer (DU) evaluation, to assess if the existing DU classification was useful and feasible in clinical practice and to investigate if the new categorisation was preferred to the simple distinction of DU in recurrent and not recurrent, in patients with systemic sclerosis (SSc).

METHODS

DeSScipher is the largest European multicentre study on SSc. It consists of five observational trials (OTs), and one of them, OT1, is focused on DU management. The DeSScipher OT1 items on DU that reached ≥ 60% of completion rate were administered to EUSTAR (European Scleroderma Trials and Research group) centres via online survey. Questions about feasibility and usefulness of the existing DU classification (DU due to digital pitting scars, to loss of tissue, derived from calcinosis and gangrene) and newly proposed categorisation (episodic, recurrent and chronic) were also asked.

RESULTS

A total of 84/148 (56.8%) EUSTAR centres completed the questionnaire. DeSScipher items scored by ≥ 70% of the participants as essential and feasible for DU evaluation were the number of DU defined as a loss of tissue (level of agreement 92%), recurrent DU (84%) and number of new DU (74%). For 65% of the centres, the proposed classification of DU was considered useful and feasible in clinical practice. Moreover, 80% of the centres preferred the categorisation of DU in episodic, recurrent and chronic to simple distinction in recurrent/not recurrent DU.

CONCLUSIONS

For clinical practice, EUSTAR centres identified only three essential items for DU evaluation and considered the proposed classification and categorisation as useful and feasible. The set of items needs to be validated while further implementation of DU classification and categorisation is warranted.

TRIAL REGISTRATION

Observational trial on DU (OT1) is one of the five trials of the DeSScipher project (ClinicalTrials.gov; OT1 Identifier: NCT01836263 , posted on April 19, 2013).

One year in review 2018: idiopathic inflammatory myopathies

Idiopathic inflammatory myopathies (IIMs) are a group of chronic autoimmune systemic diseases affecting the skeletal muscle and other organs. IIMs are also a complex group of diseases, in some cases, difficult to manage. Literature on IIMs has been growing fairly rapidly and keeping up-to-date on such a topic is of utmost importance for any rheumatologist who looks after IIM patients. Thus, the aim of this review is to summarise the most relevant literature contributions published over the last year on the pathogenesis, serology, diagnosis and treatment of IIMs.

Sirukumab for the treatment of rheumatoid arthritis: update on sirukumab, 2018

INTRODUCTION

Interleukin-6 (IL-6) is well-known for its pro-inflammatory properties, has been proven to target a wide range of cells in the joint, and has been implicated in extra-articular and articular manifestations in rheumatoid arthritis (RA). Tocilizumab (TCZ) is now widely used in patients with active RA and a number of additional agents that target the IL-6 pathways are under development, including sirukumab (SRK). Areas covered: SRK is an IgG1κ human anti-IL-6 monoclonal antibody which binds to IL-6 and prevents IL-6-mediated downstream effects. Initial trial results in phase-III studies in patients with RA seemed promising, showing improved results in patients with moderate-to-severe RA. Data derive from the phase-II study and the various SIRROUND studies (phase III). Expert commentary: The available data show that SRK50 mg every 4 weeks or 100 mg every 2 weeks will be effective in treating the RA population, with clinical improvements as early as week 2 and sustained over time. The adverse-event profile seems to be similar to TCZ, except for an increased mortality post open-label studies due to infections and cardiovascular events, our knowledge of which will be deepened with post-marketing surveillance and registry data.

One year in review 2017: idiopathic inflammatory myopathies

Every year new concepts about pathogenesis, serology, diagnosis and treatment in inflammatory myopathies (IIMs) have been provided. The purpose of this manuscript is to summarise the most relevant literature contributions published over the last year about these complex and rare diseases.

One year in review 2016: spondyloarthritis

Spondyloarthritis represents a heterogeneous group of articular inflammatory diseases that share common genetic, clinical and radiological features. Recently, novel insights into the epidemiology, pathogenesis and treatment of these diseases have been provided. Herewith, we present an overview ofthe most significant literature contributions published over the past year.

Calcinosis in systemic sclerosis: subsets, distribution and complications

OBJECTIVE

To retrospectively analyse the features of calcinosis in a cohort of SSc patients.

METHODS

Charts of SSc patients attending the Ulcer Unit of the Rheumatology Department, University of Florence and presenting a clinical suspicion of calcinosis were considered in the study. Data on clinical history, including recent skin changes, and clinical examination of all areas with suspected calcinosis, radiological imaging of the calcinotic area, demographics and SSc-related organ involvement and pain measured by a visual analogue scale were recorded.

RESULTS

In 52 of 112 SSc patients, a total of 316 calcinoses were recorded and were divided into visible and palpable {154 [47.4%], clustered according to their macroscopic features as mousse [49 (31.8%)] and stone [: 105 (68.2%)]} and non-visible but palpable {: 162 [52.6%]: net [5 (3%)], plate [22 (13.8%)] and stone [135 (83.2%)]}. The X-ray-based classification of all calcinoses, both visible and non-visible, was as follows: stone, 289 (91.4%); net, 12 (3.8%) and plate, 15 (4.8%). Skin ulcers complicated 154 of 316 calcinoses (48.7%). Mousse calcinosis was associated with pulmonary arterial hypertension, the stone subset was suggestive of pulmonary involvement and justified further investigation and the net subset was the slowest to heal.

CONCLUSION

Our data indicate that calcinosis may be classified in SSc as mousse, stone, net and plate according to its clinical and X-ray features. This classification awaits validation for a possible use in clinical practice and to support early treatment and prevention of complications.

Assessment, Definition, and Classification of Lower Limb Ulcers in Systemic Sclerosis: A Challenge for the Rheumatologist

OBJECTIVE

To evaluate pathogenesis and clinical features of lower limb ulcers in systemic sclerosis (SSc) and to propose a classification that could be used in clinical practice.

METHODS

Charts of 60 patients with SSc who had lower limb cutaneous lesions were reviewed. All patients had videocapillaroscopy and arterial and venous lower limb color Doppler ultrasonography (US). Arteriography was performed if occlusive peripheral arterial disease was suspected.

RESULTS

The 554 lesions were classified as hyperkeratosis, ulcers, and gangrenes. There were 341 (61.6%) hyperkeratoses, 208 (37.5%) ulcers, and 5 (0.9%) gangrenes. Ulcers were divided into pure ulcers, ulcers associated with hyperkeratosis, and ulcers secondary to calcinosis. Involvement of arterial and venous macrocirculation as determined by color Doppler US was observed in 17 (18.3%) and 18 (30%) patients, respectively. Seventeen out of 37 patients with pure ulcers (45.9%) presented neither venous insufficiency nor hemodynamically significant macrovascular arterial disease. In these patients, pure ulcers were most likely caused by isolated SSc-related microvascular involvement (pure microvascular ulcers). The only significant risk factor for development of pure microvascular ulcers in the multivariate analysis was the history of lower limb ulcers (OR 26.67, 95% CI 2.75-259.28; p < 0.001).

CONCLUSION

Results of our study indicate that lower limb ulcers in SSc often have a multifactorial pathogenesis that may be difficult to manage. Further studies are needed to validate the proposed classification and to assess the most appropriate management of lower limb ulcers in SSc.
