RESUMO
OBJECTIVES: To determine an US scanning protocol with the best accuracy for the diagnosis of gout and CPPD in patients with acute mono/oligo-arthritis of unknown origin. METHODS: Patients with acute mono/oligo-arthritis in whom a joint aspiration at the most clinically involved joint (target joint) was requested were consecutively enrolled. US was performed in each patient before the arthrocentesis. The accuracy of different US findings and scanning protocols for the diagnosis of gout and CPPD was calculated. RESULTS: A total of 161 subjects were included (32 gout patients, 30 CPPD patients and 99 disease-controls). US findings had a high specificity for gout (0.92-0.96) and CPPD (0.90-0.97), while the sensitivity ranged from 0.73 to 0.85 in gout (double contour sign and tophi, respectively) and from 0.60 to 0.90 in CPPD (hyaline and fibrocartilage deposits, respectively). The US assessment of two joints bilaterally (gout: knees, MTP1 joints; CPPD: knees, wrists) plus the target joint had an excellent diagnostic sensitivity (gout: 0.91, CPPD: 0.93) and specificity (gout: 0.91, CPPD: 0.89). This targeted US scanning protocol yielded to higher diagnostic accuracy compared with the US evaluation of the target joint [gout area under the curve (AUC) 0.91 vs 0.84, P = 0.03; CPPD AUC 0.93 vs 0.84, P = 0.04] unless the target joint was the knee or the MTP1 joint in gout and the knee or the wrist in CPPD. CONCLUSIONS: A targeted US scanning protocol of two joints bilaterally plus the target joint showed an excellent accuracy (>90%) for the diagnosis of crystal arthritis in patients with acute mono/oligoarthritis.

OBJECTIVES: To evaluate differences in nailfold videocapillaroscopy (NVC) findings between systemic sclerosis-SSc patients with and without a diagnosis of pulmonary arterial hypertension (PAH). METHODS: 110 SSc patients were enrolled in this cross-sectional, case-control, multi-centre study. Patients were divided into cases (SSc-PAH confirmed by right hearth catheterization-RHC) and controls (SSc-nonPAH with low probability of PAH). NVC patterns (early, active, and late) and morphological parameters (microvascular density, non-specific abnormalities, giant capillaries, micro-haemorrhages, avascular areas) were considered using a semiquantitative scoring system. RESULTS: SSc-PAH patients showed higher frequencies of late pattern (p < 0.01), non-specific abnormalities (p < 0.01), lower capillary density (p < 0.01), higher avascular areas (p < 0.01), and a higher mean NVC score (p < 0.01). Contrarily, the early/active pattern (p < 0.01) and a higher rate of micro-haemorrhages (p = 0.04) were more frequent in non-PAH patients. By the multivariate analysis, SSc-PAH patients, compared to non-PAH, had more non-specific abnormalities (27/55, 49.1% vs 10/55, 18.2%, adjusted OR: 16.89, 95%CI: 3.06-93.16), a lower capillary density (grade 3, 20/55, 36.4% vs 5/55, 9.1%, adjusted OR: 38.33, 95%CI: 2.34-367.80), and avascular areas (18/55, 32.7% vs 10/55, 18.2%, adjusted OR: 16.90, 95%CI: 2.64-44.35). A correlation was found between the mean pulmonary arterial pressure-mPAP and avascular areas (p < 0.01), capillary density (p < 0.01), and non-specific abnormalities (p < 0.01). A clinical model including the NVC variables may be able to predict the diagnosis of PAH. CONCLUSIONS: Our results indicate that the distinctive peripheral microcirculatory injury of SSc, i.e capillary loss and morphological abnormalities, appear more severe and pronounced in patients with SSc-PAH.
RESUMO
OBJECTIVES: The objectives of this study were (1) to explore US findings for muscle mass, muscle quality and muscle stiffness in SLE patients and healthy subjects; (2) to investigate the relationship between the US muscle findings and physical performance in SLE patients and healthy subjects. METHODS: Quadriceps muscle thickness was used for assessment of muscle mass, muscle echogenicity (using a visual semi-quantitative scale and grayscale analysis with histograms) for assessment of muscle quality, and point shear-wave elastography (SWE) for assessment of muscle stiffness in 30 SLE patients (without previous/current myositis or neuromuscular disorders) and 15 age-, sex- and BMI-matched healthy subjects. Hand grip strength tests and short physical performance battery (SPPB) tests were carried out in the same populations. RESULTS: No difference was observed between SLE patients and healthy subjects for quadriceps muscle thickness (35.2 mm ±s.d. 6.8 vs 34.8 mm ± s.d. 6.0, respectively, P = 0.79). Conversely, muscle echogenicity was significantly increased in SLE patients (visual semi-quantitative scale: 1.7 ± s.d. 1.0 vs 0.3 ± s.d. 0.5, respectively, P < 0.01; grayscale analysis with histograms: 87.4 mean pixels ± s.d. 18.8 vs 70.1 mean pixels ± s.d. 14.0, respectively, P < 0.01). Similarly, SWE was significantly lower in SLE patients compared with healthy subjects {1.5 m/s [interquartile range (IQR) 0.3] vs 1.6 m/s (IQR 0.2), respectively, P = 0.01}. Muscle echogenicity was inversely correlated with grip strength (visual semi-quantitative scale, Rho: -0.47, P = 0.01; grayscale analysis with histograms, Rho: -0.41, p < 0.01) and SPPB (visual semi-quantitative scale, Rho: -0.50, P < 0.01; grayscale analysis with histograms Rho: -0,46, P < 0.01). CONCLUSIONS: US assessment of muscle echogenicity and stiffness is useful for the early detection of muscle involvement in SLE patients.

PURPOSE OF REVIEW: To highlight the potential uses and applications of imaging in the assessment of the most common and relevant musculoskeletal (MSK) manifestations in systemic lupus erythematosus (SLE). RECENT FINDINGS: Ultrasound (US) and magnetic resonance imaging (MRI) are accurate and sensitive in the assessment of inflammation and structural damage at the joint and soft tissue structures in patients with SLE. The US is particularly helpful for the detection of joint and/or tendon inflammation in patients with arthralgia but without clinical synovitis, and for the early identification of bone erosions. MRI plays a key role in the early diagnosis of osteonecrosis and in the assessment of muscle involvement (i.e., myositis and myopathy). Conventional radiography (CR) remains the traditional gold standard for the evaluation of structural damage in patients with joint involvement, and for the study of bone pathology. The diagnostic value of CR is affected by the poor sensitivity in demonstrating early structural changes at joint and soft tissue level. Computed tomography allows a detailed evaluation of bone damage. However, the inability to distinguish different soft tissues and the need for ionizing radiation limit its use to selected clinical circumstances. Nuclear imaging techniques are valuable resources in patients with suspected bone infection (i.e., osteomyelitis), especially when MRI is contraindicated. Finally, dual energy X-ray absorptiometry represents the imaging mainstay for the assessment and monitoring of bone status in patients with or at-risk of osteoporosis. Imaging provides relevant and valuable information in the assessment of MSK involvement in SLE.

OBJECTIVES: To establish the weight of the subjective components of the Disease Activity index for Psoriatic Arthritis (DAPSA) in psoriatic arthritis (PsA) patients and comorbid fibromyalgia syndrome (FM). METHODS: In PsA patients not fulfilling the DAPSA remission, it has been calculated the DAPSA-patient (DAPSA-P), an index represented by the ratio between the sum of the subjective components (tender joint count+patient global assessment of disease activity+visual analogue scale pain) and DAPSA in its entirety (swollen joint count+tender joint count+patient global assessment of disease activity+visual analogue scale pain+C-reactive protein [in mg/ dl]). The DAPSA-P ranges from 0 to 1, and values closer to 1 suggest a major weight of the subjective components, while values closer to 0 indicate a greater contribution of the swollen joint count and C-reactive protein, the two factors more closely related to inflammation. It was also defined as the presence of a comorbid FM, and it was established the DAPSA-P cut-off point distinguishing for the presence of a comorbid FM through the receiver operating characteristic (ROC) curve analysis. RESULTS: DAPSA-P was higher in all PsA+FM patients. Analysing the receiver operating characteristic curve, the DAPSA-P cut-off distinguishing a comorbid FM was 0.775. CONCLUSIONS: DAPSA-P can help to measure how comorbid FM inflates DAPSA.

OBJECTIVES: Systemic sclerosis (SSc) is a severe multiple-organ disease characterised by unpredictable clinical course, inadequate response to treatment, and poor prognosis. National SSc registries may provide large and representative patients cohorts required for descriptive and prognostic studies. Therefore, the Italian Society for Rheumatology promoted the registry SPRING (Systemic sclerosis Progression INvestiGation). METHODS: The SPRING is a multi-centre rheumatological cohort study encompassing the wide scleroderma spectrum, namely the primary Raynaud's phenomenon (pRP), suspected secondary RP, Very Early Diagnosis of Systemic Sclerosis (VEDOSS), and definite SSc. Here we describe the demographic and clinical characteristics of a population of 2,028 Italian patients at the initial phase of enrolment, mainly focusing on the cohort of 1,538 patients with definite SSc. RESULTS: Definite SSc showed a significantly higher prevalence of digital ulcers, capillaroscopic 'late' pattern, oesophageal and cardio-pulmonary involvement compared to VEDOSS, as expected on the basis of the followed classification criteria. The in-depth analysis of definite SSc revealed that male gender, diffuse cutaneous subset, and anti-Scl70 seropositivity were significantly associated with increased prevalence of the most harmful disease manifestations. Similarly, patients with very short RP duration (≤1 year) at SSc diagnosis showed a statistically increased prevalence of unfavourable clinico-serological features. CONCLUSIONS: Nationwide registries with suitable subsetting of patients and follow-up studies since the prodromal phase of the disease may give us valuable insights into the SSc natural history and main prognostic factors.

OBJECTIVE: To investigate efficacy, safety and survival of belimumab and to identify predictors of drug response and drug discontinuation in patients with active SLE in clinical practice. PATIENTS AND METHODS: Data of SLE patients, treated with belimumab, from 11 Italian prospective cohorts were analyzed. SLEDAI-2K, anti-dsDNA, C3, C4, prednisone daily dose, DAS-28, 24-h proteinuria, CLASIa (Cutaneous LE Disease Area and Severity Index Activity) were recorded at baseline and every 6 months. SLE Responder Index-4 (SRI-4) was calculated at 12 and 24 months. Demographic and clinical features and comorbidities were included in the univariate and multivariate analysis. Adverse events were recorded at each visit. Statistics was performed using the SPSS software. RESULTS: We studied 188 SLE patients, mean follow-up 17.5 ± 10.6 months. The most frequent manifestations, which required the use of belimumab, were polyarthritis (45.2%) and skin rashes (25.5%). SRI-4 was achieved by 77.0% and 68.7% of patients at 12 and 24-months. Independent predictors of 12-month response were SLEDAI-2K ≥ 10 (OR 40.46, p = 0.001) and polyarthritis (OR 12.64, p = 0.001) and of 24-month response were SLEDAI-2K ≥ 10 (OR 15.97, p = 0.008), polyarthritis (OR 32.36, p = 0.006), and prednisone ≥7.5 mg/day (OR 9.94, p = 0.026). We observed a low rate of severe adverse events. Fifty-eight patients (30.8%) discontinued belimumab after a mean follow-up of 10.4 ± 7.5 months. The drug survival was 86.9%, 76.9%, 69.4%, 67.1%, and 61.9% at 6, 12, 18, 24, and 30 months, respectively. No factors associated with drug discontinuation were found. CONCLUSION: Belimumab is effective and safe when used in clinical practice setting.

Objectives: The main objective of this study is to explore the prevalence and distribution of entheseal US changes in a cohort of SLE patients, taking as controls a group including both PsA patients and healthy subjects. The secondary objective is to investigate the correlation between the US findings and the clinical and serological data in SLE patients. Methods: Clinical and US assessment of quadriceps, patellar and Achilles tendons, and plantar fascia entheses were performed by independent rheumatologists on 65 patients with SLE, 50 patients with PsA and 50 healthy subjects. US findings were identified according to the OMERACT definitions. In SLE patients, the correlation between the US changes and the clinical and laboratory findings was evaluated. Results: US revealed one or more abnormalities in at least one enthesis in 44 out of 65 SLE patients (67.7%), 47 out of 50 PsA patients (94.0%) and 22 out of 50 healthy subjects (44.0%). In SLE patients, US findings indicating active inflammation were significantly more frequently detected than in healthy subjects (P < 0.001). The distal enthesis of the patellar tendon was the most commonly involved. The presence of power Doppler signal at the enthesis was an independent predictor of SLE disease activity (SLEDAI-2k P < 0.001, ß = 0.52; musculoskeletal-BILAG P < 0.001, ß = 0.56). Conclusion: The burden of entheseal sonographic changes was significantly higher in SLE patients than in healthy subjects, especially as regards active inflammation. The presence of power Doppler signal at the enthesis may represent a potential biomarker of SLE disease activity.

To determine the prevalence of fibromyalgia (FM) in patients with ankylosing spondylitis (AS) or psoriatic arthritis (PsA) characterized by axial involvement (axial-PsA), and to assess the discriminative ability of different versions of the Ankylosing Spondylitis Disease Activity Score (ASDAS) and the Bath Ankylosing Spondylitis Activity Disease Activity Index (BASDAI) in measuring disease activity in three different cohorts of patients with axial spondyloarthritis (axial-SpA), FM, or both (axial-SpA + FM), this study was divided into two phases: (1) 402 patients with definite AS or axial-PsA were examined to diagnose FM and estimate its prevalence; and (2) 419 patients (111 with axial-SpA, 248 with FM, and 60 with aSpA + FM) were evaluated using the different versions of the ASDAS and BASDAI to assess the effect on disease activity. The overall prevalence of FM in the axial-SpA population was 14.9 %, significantly higher among women (p < 0.0001); the estimated prevalence in AS was 12.7 % and in axial-PsA was 17.2 %. Although the BASDAI scores correlated with those of ASDAS-C-reactive protein (CRP) and ASDAS-erythrocyte sedimentation rate (ESR) (p < 0.0001), only ASDAS had sufficient discriminatory ability to assess disease activity. The addition of only one marker of inflammation led to an adequate level of significance (ASDAS-CRP, p = 0.0018; ASDAS-ESR, p = 0.003). FM is common in axial-SpA and more prevalent in female patients. Our findings suggest that ASDAS is better than BASDAI in distinguishing patients with disease activity from those with functional impairment. The use of ASDAS may be very useful in clinical practice as it allows treating patients with the most appropriate therapy.

The aim of this paper is to identify factors associated with interstitial lung disease (ILD) in patients with systemic sclerosis (SSc) and build an algorithm to better define this association for a personalised application in clinical practice. METHODS: A total of 78 SSc patients underwent HRCT to assess ILD. Demographic, clinical and laboratory variables were collected, focusing on those associated either directly or indirectly with lung involvement. The discriminant value of each variable was determined using the operating characteristic curves (ROC) and included in a model to estimate the strength of ILD association in SSc. RESULTS: Thirty-three (42.31%) patients showed ILD on HRCT. DLco, M-Borg, GERD-Q and capillary density were significantly associated with the presence of ILD-SSc. A model including these variables had a coefficient of determination (R2) of 0.697. DLco had an AUC of 0.861 (p < 0.001) with a cut-off of ≤72.3% (sensitivity 78.8%, specificity 91.1%, +LR 8.86). The m-Borg Scale showed an AUC of 0.883 (p < 0.001) with a cut-off >2 (sensitivity 84.8%, specificity 82.2%, +LR 4.77), GERD-Q had an AUC of 0.815 (p < 0.001) with a cut-off >7 (sensitivity 72.7%, specificity 86.7%, +LR 5.45). The capillary density showed an AUC of 0.815 (p < 0.001) with a cut-off of ≤4.78 (sensitivity 87.9%, specificity 68.9%, +LR 2.82). Based on the pre-test probability values, these four variables were applied to Fagan's nomogram to calculate the post-test probability of this association. CONCLUSIONS: Our study identified four associated clinical factors of ILD in SSc patients. Moreover, their inclusion in an algorithm for the post-test probability, tailored to the specific patients' characteristics, significantly increases the ability to find out the presence of SSc-ILD.
RESUMO
OBJECTIVES: The current knowledge about the role of comorbidities in systemic sclerosis (SSc) is limited. Therefore, the aim of this study was to evaluate the prevalence of comorbidities and their impact on disease activity and prognosis in the Systemic sclerosis PRogression INvestiGation (SPRING) registry. METHODS: SSc patients from the SPRING registry, fulfilling the ACR/EULAR 2013 classification criteria, with complete data on baseline comorbidities were enrolled. The Charlson comorbidity index (CCI) was used to quantify the overall comorbidity burden. The disease activity was calculated using the revised EUSTAR activity index (AI). The impact of SSc features on CCI, the effect of CCI on SSc disease activity and mortality were tested with multivariable regression models. RESULTS: Among 1910 SSc patients enrolled, 67.3 % had at least one comorbidity at baseline. The most frequent comorbidities were systemic arterial hypertension (23.7 %), osteoporosis (12.9 %) and dyslipidemia (11 %). The mean value of CCI score was 2.0 ± 1.8. When patients were grouped according to increasing levels of CCI, a clear separation in the distribution of SSc-related clinical features could be observed. Among over 900 patients with available follow-up, no association between baseline CCI and changes in disease activity was observed. Conversely, the risk of death over time was independently predicted by both CCI and AI. CONCLUSIONS: Comorbidities and disease activity independently impact on the prognosis of SSc patients. This suggests that the management of comorbidities, together with the reduction of disease activity, is fundamental to improve patient survival.
RESUMO
Nailfold capillaroscopy has been extensively applied in a broad spectrum of pathologic conditions, but very few data have been published in healthy individuals. The aim of this study was to describe the nailfold capillary findings on a large series of healthy subjects using the video-capillaroscopy technique. Nailfold capillaries were studied based on their morphology, dimensions and density. Then, to evaluate jointly the association between different capillary findings in groups of subjects which were homogeneous for their characteristics, cluster analysis was performed. The results (median) of capillary measurements were as follows: loop length 207µm, external diameter 39µm, internal diameter 17µm, apical diameter 17µm, and intercapillary distance 143µm. Based on the cluster analysis three major "normal" morphologic capillaroscopic patterns were depicted: 1) the "normal" pattern mainly with 2 to 5 U-shaped loops/mm and ≤2 tortuous loops/mm; 2) the "perfect normal" pattern with ≥5 U-shaped loops/mm and 3) the "unusual normal" with at least 1 meandering or bushy loop, or at least 1 microhemorrhage, or with >4 crossed loops/mm. Regarding the loop measurements, the majority of subjects had a median of 7capillaries/mm with a median length of 198µm.

Objectives: The aim was to explore the inter-reliability of a newly developed US scanning protocol (multimodal US) for the assessment of different aspects of sarcopenia-related muscle involvement, including muscle mass, muscle quality and muscle stiffness [using point shear-wave elastography (SWE)], in patients with rheumatic and musculoskeletal diseases (RMDs). Methods: Quadriceps muscle mass (i.e. muscle thickness), muscle quality (i.e. muscle echogenicity evaluated with both a visual semi-quantitative scale and a dedicated software package for image analysis, ImageJ) and point SWE measurements were obtained by two rheumatologists (blinded to each other's evaluation) in consecutive RMD patients without previous/current myositis or neuromuscular disorders.Inter-reliability was assessed using the intraclass correlation coefficient (ICC) for continuous variables and Cohen's kappa (κ) for categorical variables. Results: A total of 45 RMD patients were enrolled [mean age 54.5 (16.0) years, male-to-female ratio 1:1.5, mean BMI 24.6 (4.6) kg/m2], 10 with PsA, 7 RA, 5 AS, 5 PMR, 4 SLE, 4 gout, 4 OA, 3 FM and 3 SSc. The grade of inter-rater reliability was excellent for muscle mass [ICC = 0.969 (0.953 < ICC < 0.979)]. Regarding muscle echogenicity, the agreement was substantial/almost perfect using the visual semi-quantitative scale (weighted linear = 0.793, weighted squared = 0.878) and excellent using ImageJ analysis [ICC = 0.916 (0.876 < ICC < 0.944)]. Finally, a good agreement was obtained for point SWE measurements [ICC = 0.76 (0.712 < ICC < 0.8)]. Conclusion: Multimodal US is a novel and reliable tool for the evaluation of different aspects of muscle involvement (muscle mass, muscle quality and muscle stiffness) in RMD patients.
RESUMO
OBJECTIVES: To better define the spectrum of new-onset post-COVID-19 and post-COVID-19 vaccine inflammatory rheumatic diseases (IRD) from a large multicentric observational study. METHODS: Consecutive cases of IRD encountered during a 12-month period and satisfying one of the following inclusion criteria: (a) onset of the rheumatic manifestations within 4 weeks from SARS-CoV-2 infection or (b) onset of the rheumatic manifestations within 4 weeks from the administration of one of the COVID-19 vaccines ws recruited. RESULTS: The final analysis cohort comprised 267 patients, of which 122 (45.2%) in the post-COVID-19 and 145 (54.8%) in the postvaccine cohort. Distribution of IRD categories differed between the two cohorts: the post-COVID-19 cohort had a higher percentage of patients classified as having inflammatory joint diseases (IJD, 52.5% vs 37.2%, p=0.013) while the post-vaccine cohort had a higher prevalence of patients classified as polymyalgia rheumatica (PMR, 33.1% vs 21.3%, p=0.032). No differences were detected in the percentage of patients diagnosed with connective tissue diseases (CTD 19.7% vs 20.7%, p=0.837) or vasculitis (6.6% vs 9.0%, p=0.467). Despite the short follow-up period, IJD and PMR patients' response to first-line therapy was favourable, with both groups achieving a drop in baseline disease activity scores of ~30% and ~70% respectively. CONCLUSION: Our article reports the largest cohort published to date of new-onset IRD following SARS-CoV-2 infection or COVID-19 vaccines. Although causality cannot be ascertained, the spectrum of possible clinical manifestations is broad and includes IJD, PMR, CTD and vasculitis.

AIM: To assess the efficacy of belimumab in joint and skin manifestations in a nationwide cohort of patients with SLE. METHODS: All patients with skin and joint involvement enrolled in the BeRLiSS cohort were considered. Belimumab (intravenous, 10 mg/kg) effectiveness in joint and skin manifestations was assessed by DAS28 and CLASI, respectively. Attainment and predictors of DAS28 remission (<2.6) and LDA (≥2.6, ≤3.2), CLASI = 0, 1, and improvement in DAS28 and CLASI indices ≥20%, ≥50%, and ≥70% were evaluated at 6, 12, 24, and 36 months. RESULTS: DAS28 < 2.6 was achieved by 46%, 57%, and 71% of patients at 6, 12, and 24 months, respectively. CLASI = 0 was achieved by 36%, 48%, and 62% of patients at 6, 12, and 24 months, respectively. Belimumab showed a glucocorticoid-sparing effect, being glucocorticoid-free at 8.5%, 15.4%, 25.6%, and 31.6% of patients at 6, 12, 24, and 36 months, respectively. Patients achieving DAS-LDA and CLASI-50 at 6 months had a higher probability of remission at 12 months compared with those who did not (p = 0.034 and p = 0.028, respectively). CONCLUSIONS: Belimumab led to clinical improvement in a significant proportion of patients with joint or skin involvement in a real-life setting and was associated with a glucocorticoid-sparing effect. A significant proportion of patients with a partial response at 6 months achieved remission later on during follow-up.
RESUMO
OBJECTIVE: To describe demographic, clinical and laboratory features of systemic sclerosis sine scleroderma (ssSSc) in a large multicentre systemic sclerosis (SSc) cohort. METHODS: Data involving 1808 SSc patients from Italian Systemic sclerosis PRogression INvestiGation registry were collected. The ssSSc was defined by the absence of any cutaneous sclerosis and/or puffy fingers. Clinical and serological features of ssSSc were compared with limited cutaneous (lcSSc) and diffuse cutaneous (dcSSc) subsets. RESULTS: Among patients with SSc, only 61 (3.4%) were classified as having ssSSc (F/M=19/1). Time from Raynaud's phenomenon (RP) onset to diagnosis was longer in ssSSc (3 years, IQR 1-16.5) than lcSSc (2 years, IQR 0-7), and dcSSc (1 year, IQR 0-3) (p<0.001). Clinical ssSSc phenotype was comparable to lcSSc, except for digital pitting scars (DPS) (19.7% vs 42%, p=0.01), but significantly milder than dcSSc, particularly for digital ulcers (DU) (6.6% vs 35.7%, p<0.001), oesophagus (46.2% vs 63.5%, p=0.009), lung (mean diffusion capacity for carbon monoxide 72.2±19.6 vs 62.4±22.8, p=0.009; mean forced vital capacity 105.6±21.7 vs 89.2±20.9, p<0.001) and major videocapillaroscopic alterations (late pattern 8.6% vs 47.6%, p<0.001). Moreover, in ssSSc the percentages of anticentromere and antitopoisomerase were comparable to lcSSc (40% and 18.3% vs 36.7% and 26.6%), but divergent respect to dcSSc (8.6% and 67.4%, p<0.001). CONCLUSION: The ssSSc is a quite rare disease variant characterised by clinico-serological features comparable to lcSSc, but significantly different from dcSSc. Overall, longer RP duration, low percentages of DPS and peripheral microvascular abnormalities, and increased anti-centromere seropositivity distinguish ssSSc. Further investigations based on national registries might provide useful insights on the actual relevance of the ssSSc within the scleroderma spectrum.

Introduction: The impact of COVID-19 pandemic represents a serious challenge for 'frail' patients' populations with inflammatory autoimmune systemic diseases such as systemic sclerosis (SSc). We investigated the prevalence and severity of COVID-19, as well the effects of COVID-19 vaccination campaign in a large series of SSc patients followed for the entire period (first 38 months) of pandemic. Patients and method: This prospective survey study included 1755 unselected SSc patients (186 M, 1,569F; mean age 58.7 ± 13.4SD years, mean disease duration 8.8 ± 7.3SD years) recruited in part by telephone survey at 37 referral centers from February 2020 to April 2023. The following parameters were carefully evaluated: i. demographic, clinical, serological, and therapeutical features; ii. prevalence and severity of COVID-19; and iii. safety, immunogenicity, and efficacy of COVID-19 vaccines. Results: The prevalence of COVID-19 recorded during the whole pandemic was significantly higher compared to Italian general population (47.3 % vs 43.3 %, p < 0.000), as well the COVID-19-related mortality (1.91 % vs 0.72 %, p < 0.001). As regards the putative prognostic factors of worse outcome, COVID-19 positive patients with SSc-related interstitial lung involvement showed significantly higher percentage of COVID-19-related hospitalization compared to those without (5.85 % vs 1.73 %; p < 0.0001), as well as of mortality rate (2.01 % vs 0.4 %; p = 0.002). Over half of patients (56.3 %) received the first two plus one booster dose of vaccine; while a fourth dose was administered to 35.6 %, and only few of them (1.99 %) had five or more doses of vaccine. Of note, an impaired seroconversion was recorded in 25.6 % of individuals after the first 2 doses of vaccine, and in 8.4 % of patients also after the booster dose. Furthermore, the absence of T-cell immunoreactivity was observed in 3/7 patients tested by QuantiFERON® SARSCoV-2 Starter Set (Qiagen). The efficacy of vaccines, evaluated by comparing the COVID-19-related death rate recorded during pre- and post-vaccination pandemic periods, revealed a quite stable outcome in SSc patients (death rate from 2.54 % to 1.76 %; p = ns), despite the significant drop of mortality observed in the Italian general population (from 2.95 % to 0.29 %; p < 0.0001). Conclusions: An increased COVID-19 prevalence and mortality rate was recorded in SSc patients; moreover, the efficacy of vaccines in term of improved outcomes was less evident in SSc compared to Italian general population. This discrepancy might be explained by concomitant adverse prognostic factors: increased rate of non-responders to vaccine in SSc series, low percentage of individuals with four or more doses of vaccine, ongoing immunomodulating treatments, disease-related interstitial lung disease, and/or reduced preventive measures in the second half of pandemic. A careful monitoring of response to COVID-19 vaccines together with adequate preventive/therapeutical strategies are highly recommendable in the near course of pandemic in this frail patients' population.
