OBJECTIVES:SSc is characterized by widespread microangiopathy and fibrosis of skin and visceral organs. Left ventricle involvement is usually subclinical, characterized by systolic and/or diastolic dysfunction. The global longitudinal strain (GLS), a validated and reliable technique for the measurement of ventricular longitudinal deformation by means of echocardiography, may detect subclinical systolic dysfunction of SSc myocardium. The improvement of myocardial perfusion by means of intravenous Iloprost administration could ameliorate the contractility of SSc heart. Therefore, we aimed to evaluate GLS in a series of SSc patients prior and after Iloprost infusion. METHODS:Fifteen consecutive SSc patients (age: 54 ± 11 years; 12 females) treated with Iloprost because of the presence/history of digital ulcers underwent echocardiography, including GLS technique. This evaluation was conducted immediately before Iloprost administration and at the end of the 6-h infusion session. RESULTS:Significant improvement in the mean GLS was observed after Iloprost administration (from -13.5 ± 2.5 to -15 ± 3.3; P = 0.011). The echocardiographic data obtained from the four-chamber view showed the best quality for GLS analysis and showed a highly significant improvement of the strain after Iloprost administration (from -13.4 ± 2.2 to -15.6 ± 3; P = 0.001). The degree of GLS improvement did not correlate with any SSc parameters. CONCLUSION:Iloprost administration improved GLS, suggesting that the increase of myocardial perfusion allowed, at least in part, a correction of left ventricular systolic dysfunction. Further studies are needed to confirm these findings, further exploring the mid/long-term effects of Iloprost on myocardial contraction.

Although the pathophysiology and therapy of microvascular damage was so far addressed by both rheumatologists and angiologists, cardiac disease related to Systemic sclerosis (SSc) remained obscure or misdiagnosed for long time. Although its pathogenetic chain is far to be completely understood, myocardial fibrosis and microvascular dysfunction play a prominent role in the clinical history of patients with SSc. Bearing in mind that it is one of the main causes of death and disabilities for SSc patients, an early screening has become mandatory at time of diagnosis, and then every year during the follow-up. Moreover, the prevalence of coronary heart disease in SSc resulted comparable, in older patients, to that of patients with type 2 diabetics. Global longitudinal strain (GLS), a well-known early echocardiographic marker of cardiac dysfunction, has been recently shown to be a useful tool predicting prognosis and effects of therapy in SSc. Target therapy for primary cardiac disease in SSc is so far not well established. Inhibitor of IL-1 and IL-6 are under investigation. The acute infusion of iloprost ameliorates the baseline depressed GLS of left ventricle in patients with SSc, but this beneficial effect remains to be confirmed during chronic treatment.

OBJECTIVES:We investigated the effectiveness and safety of filgotinib in a real-life multicentre cohort of rheumatoid arthritis (RA) patients. METHODS:RA patients were evaluated at baseline and after 12 and 24 weeks and were stratified based on previous treatments as biologic disease-modifying anti-rheumatic drug (bDMARD)-naive and bDMARD-insufficient responders (IR). Concomitant usage of methotrexate (MTX) and oral glucocorticoids (GC) was recorded. At each timepoint we recorded disease activity, laboratory parameters and adverse events. RESULTS:126 patients were enrolled. 15.8% were bDMARD-naive (G0), while 84% were bDMARD-IR (G1). In G0, 45% of patients were in monotherapy (G2) and 55% were taken MTX (G3). In G1, 50% of patients were in monotherapy (G4) and 50% used MTX (G5).A significant reduction in all parameters at 12 weeks was observed; in the extension to 24 weeks the significant reduction was maintained for patient global assessment (PGA), examiner global assessment (EGA), visual analogue scale (VAS) pain, VAS fatigue, disease activity score (DAS)28- C-reactive protein (CRP) and CRP values. Filgotinib in monotherapy showed better outcomes in bDMARD-naive patients, with significant differences for patient reported outcomes (PROs) and DAS28-CRP. At 12 weeks, low disease activity (LDA) and remission were achieved in a percentage of 37.2 % and 10.7 % by simplified disease activity index (SDAI), 42.6 % and 5.7 % by clinical disease activity index (CDAI), 26.8 % and 25.2 % by DAS28-CRP, respectively. A significant decrease in steroid dose was evidenced in all patients. We observed a major adverse cardiovascular event in one patient and an increase in transaminase in another. No infections from Herpes Zoster were reported. CONCLUSIONS:Our real-world data confirm the effectiveness and safety of filgotinib in the management of RA, especially in bDMARD-naive patients.

ObjectivesTo assess the reversibility of retinal microvascular changes in the long term and to investigate the potential links with other vascular diseases of COVID-19.MethodsWe designed a prospective multicenter observational study. Patients were enrolled from the Methuselah study cohort. Retinal vascular function was studied in these patients using optical coherence tomography angiography (OCTA); aortic stiffness was measured using aortic pulse wave velocity. These examinations were performed 1 (Visit 1) and 12 (Visit 2) months after the hospital discharge for severe COVID-19. A control subject group matched for age and sex was included to define normal values.ResultsA total of 28 control subjects (56 eyes) and 25 patients (50 eyes) completed the scheduled OCTA assessment; 18 patients (36 eyes) also completed the macrovascular examination. Compared to controls, the vessel density of the superficial capillary plexus (SCP) was reduced, whereas the foveal avascular zone area was enlarged at Visit 1 (p = 0.016 and < 0.001, respectively) and was not modified after the 12-month follow-up in COVID-19 patients (p = 0.011 and 0.001, respectively). Higher inflammation and lower renal function during hospitalization were linked to higher aortic stiffness and reduced vessel density of the SCP 1 month after the acute phase of COVID-19. A slower recovery of aortic dysfunction was linked to worse retinal vascular outcomes at Visit 2.ConclusionRetinal vascular alterations were not reversible 12 months after COVID-19 and were linked to inflammation and renal dysfunction during hospitalization as well as to aortic stiffness measured during follow-up.

BACKGROUND:We proposed the term "UIPAF" to define patients with Usual Interstitial Pneumonia (UIP) associated with only one domain of the classification called "Interstitial Pneumonia with Autoimmune Features" (IPAF). The objective of this study was to evaluate the clinical presentation and prognosis of UIPAF patients, compared with two cohorts, composed of IPAF and idiopathic pulmonary fibrosis (IPF) patients, respectively. METHODS:The patients were enrolled as IPAF, UIPAF, or IPF based on clinical, serological, and radiological data and evaluated by a multidisciplinary team. RESULTS:We enrolled 110 patients with IPF, 69 UIPAF, and 123 IPAF subjects. UIPAF patients were similar to IPAF regarding autoimmune features, except for the prevalence of Rheumatoid Factor in UIPAF and anti-SSA in IPAF. A similar proportion of the two cohorts progressed toward a specific autoimmune disease (SAD), with differences in the kind of SAD developed. The real-life management and prognosis of UIPAF patients proved to be almost identical to IPF. CONCLUSIONS:UIPAF shared with IPAF similar autoimmune features, suggesting the opportunity to be considered IPAF, excluding the morphological domain by the classification. However, the real-life management and prognosis of UIPAF are similar to IPF. These data suggest a possible modification in the therapeutic management of UIPAF.

Background Immune and vascular ageing are proposed risk factors for giant cell arteritis (GCA). Data on the impact of age at diagnosis of GCA on the clinical presentation and course of the disease are scarce. Methods Patients with GCA followed at referral centres within the Italian Society of Rheumatology Vasculitis Study Group were enrolled up to November 2021. Patients were grouped according to age at diagnosis: ≤64, 65–79 and ≥80 years old. Results The study included 1004 patients, mean age 72.1±8.4, female 70.82%. Median follow-up duration was 49 (IQR 23–91) months. Patients in the oldest group (≥80 years) had significantly more cranial symptoms, ischaemic complications and risk for blindness compared with the groups 65–79 and ≤64 years (blindness: 36.98% vs 18.21% vs 6.19%; p<0.0001). Large-vessel-GCA was more frequent in the youngest group (65% of patients). Relapses occurred in 47% of patients. Age did not influence the time to first relapse, nor the number of relapses. Older age was negatively associated with the number of adjunctive immunosuppressants. Patients >65 years old had 2–3 fold increased risk for aortic aneurysm/dissection up to 60 months follow-up. Serious infections, but not other treatment-related complications (hypertension, diabetes, osteoporotic fractures), were significantly associated with older age. Mortality occurred in 5.8% of the population with age >65, cranial and systemic symptoms as independent risk factors. Conclusions The highest risk of ischaemic complications, aneurysm development, serious infections and the possible undertreatment make of GCA a very challenging disease in the oldest patients.

Background Fibromyalgia (FM) is a chronic widespread pain syndrome of unknown origin that leads to hypersensitivity for physical, chemical and/or psychic triggers. Vaccination, as an inflammatory stimulus and as a psychologically stressful act, could represent a challenge for these patients. Objectives We aimed to investigate the incidence of adverse reactions after vaccination for Sars-Cov2 in a series of FM patients versus healthy controls. Methods We recruited 65 consecutive FM patients classified according to the 2016 ACR diagnostic criteria¹ (M/F: 5/60; mean age 53.6 +/-12.5 years), without other associated rheumatologic conditions, and 65 age/sex-matched healthy controls. All patients filled a questionnaire in order to investigate eventual adverse events occurring up to 6 months after administration of a Sars-Cov2 vaccine. The questionnaire was divided into two parts: the first part included the patient’s demographic information, the vaccine type performed and the anamnestic data. In the second part, the individuals described all new symptoms or signs occurred after the first, the second or the third dose of Sars-Cov2 vaccine. Results Overall, FM patients reported a higher frequency of adverse events after Sars-Cov2 vaccination in comparison with healthy controls. In particular, 44/65 FM patients vs. 11/65 controls complained of exacerbation of diffuse pain (p<0.001). Fatigue, diarrhea, sweating, tingles, headache, dizziness, transient respiratory discomfort, and paroxysmal vision blurring were also more frequent in FM patients than controls (47/65 vs. 30/65, p=0.004; 6/65 vs. 0/65, p=0.028; 18/65 vs. 8/65, p=0.047; 20/65 vs. 0/65, p<0.001; 22/65 vs. 9/65, p=0.013; 21/65 vs. 5/65, p<0.001; 10/65 vs 1/65, p=0.009; 17/65 vs. 2/65, p< 0.001, respectively). No significant difference between FM and the control group as regards fever was reported (24/65 vs. 30/65; p=0.7). Interestingly, swelling at the injection vaccine site was more commonly reported in controls (9/65 vs. 20/65; p=0.034). Finally, one case of Bell’s palsy was registered in the FM series while one case of myocarditis in the control group. Conclusion FM patients showed an increased frequency of adverse events to Sars-Cov2 vaccination compared to healthy controls. In particular, all the symptoms reported seemed to be associated with the functional hypersensitivity that characterizes FM.

Background: Connective tissue diseases (CTDs) are responsible for about 20% of interstitial lung disease (ILD) cases, but their diagnosis in a pulmonary unit (PU) is not always straightforward due to a heterogeneous clinical picture. Objectives: The aim of this study was to evaluate the clinical presentation of rheumatoid arthritis (RA) and CTD-ILD cases diagnosed in PU, compared to RA and CTD patients diagnosed in a rheumatologic unit (RU). Methods: Patients with RA, systemic sclerosis (SSc), primary Sjӧgren’s syndrome (pSS), and idiopathic inflammatory myopathy were retrospectively enrolled from an RU and a PU designated to manage ILD during a period from January 2017 to October 2022. The classification of CTD-PU was carried out in a multidisciplinary setting, including the same rheumatologists that diagnosed CTD in the RU. Results: ILD-CTD-PU patients were prevalently male and older. Progression from undifferentiated CTD to a specific condition was more common in ILD-CTD-PU, and those patients generally obtained a lower score on specific classification criteria. RA-PU patients resembled polymyalgia rheumatica in 47.6% of cases, also showing a greater proportion of typical joint deformities (p = 0.02). SSc-PU patients showed a usual interstitial pneumonia pattern in 76% of cases and, compared with SSc-RU, were more commonly seronegative (p = 0.03) and generally lacked fingertip lesions (p = 0.02). The majority of the diagnoses of pSS-PU were in patients with previously diagnosed ILD, in which seropositivity and sicca syndrome developed during follow-up. Conclusions: CTD-ILD patients diagnosed in the PU show severe lung involvement and a nuanced autoimmune clinical picture.

A pancreatic neuroendocrine tumor (Pan-NET) is a rare neoplasm originating in the neuroendocrine system. Carcinoid syndrome occurs in approximately 19% of patients with functional Pan-NETs, typically when liver metastases occur. In this paper, we describe the case of a patient with a low-grade non-functional Pan-NET, but with a typical clinical presentation of carcinoid syndrome. An 81-year-old male was admitted to our Department of Internal Medicine at Cannizzaro Hospital (Catania, Italy) because of the onset of abdominal pain with nausea, loose stools, and episodic flushing. Firstly, an abdominal contrast-enhanced CT scan showed a small pancreatic hyper-vascular mass; then, a gallium-68 DOTATOC integrated PET/CT revealed an elevated expression of SSTR receptors. Serum chromogranin A and urinary 5-HIAA measurements were negative. We performed an endoscopic ultrasonography (EUS) by a fine-needle biopsy (EUS-FNB), allowing the immunostaining of a small mass (0.8 cm) and the diagnosis of a low-grade (G1) non-functional Pan-NET (NF-Pan-NET). Surgery was waived, while a follow-up strategy was chosen. The early recognition of Pan-NETs, although rare, is necessary to improve the patient’s survival. Although helpful to allow for immunostaining, EUS-FNB needs to be warranted in future studies comparing EUS-FNB to EUS-FNA (fine-needle aspiration), which is, to date, reported as the tool of choice to diagnose Pan-NETs.

Fibromyalgia (FM) is a common rheumatologic disorder characterised by widespread muscular pain. Myalgia is also a common clinical feature in Connective Tissue Disease (CTD), and FM should be studied for the concomitant presence of a CTD. The aim of this study is to evaluate the prevalence of Myositis-Specific and Myositis-Associated Antibodies (MSA/MAA) in a cohort of FM patients. We enrolled 233 consecutive FM patients (defined according to the 2016 criteria) that did not report clinical signs of autoimmune disorders and followed them for at least one year. The patients were tested for MSA/MAA with immunoblotting. FM patients were seropositive for Antinuclear Antibodies (ANA) in 24% of cases, for MSA in 9%, and for MAA in 6%. A specific diagnosis of CTD was made in 12 patients (5.2%), namely, 5 cases of primary Sjögren’s Syndrome and 7 of Idiopathic Inflammatory Myopathy. Seropositive patients showed clinical features similar to those who were seronegative at baseline. A CTD diagnosis was associated with ANA positivity (p = 0.03, X2 4.9), the presence of a speckled pattern (p = 0.02, X2 5.3), positivity for MAA (p = 0.004, X2 8.1), and MSA (p = 0.003, X2 9.2). In conclusion, a non-negligible proportion of FM patients may be seropositive for MSA/MAA, and that seropositivity might suggest a diagnosis of CTD.

All severe cases of SARS-CoV-2 infections are characterized by a high risk of disease progression towards ARDS, leading to a bad outcome. Respiratory symptoms in COVID-19 patients often do not correspond to disease's worsening. In our sample, median age was 74 years (72-75) and 54% were men. The median period of hospitalization was 9 days. Firstly, we observed a significant asynchronous trend of neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) in 764 selected among 963 patients, who were consecutively recruited in two hospitals (Cannizzaro, S. Marco) in Catania, Italy. NLR values in deceased patients showed an increase from baseline over time. By contrast, CRP tended to fall from baseline to median day of hospitalization in all three subgroups, but steeply increased at the end of hospitalization only in ICU-admitted patients. Then, we evaluated the relationships between NLR and CRP as continuous variables with PaO2/FiO(2) ratio (P/F). NLR was an independent predictor of mortality (HR: 1.77, p < 0.0001), while ICU admission was more significantly associated with CRP (HR: 1.70, p < 0.0001). Finally, age, neutrophils, CRP, and lymphocytes are significantly and directly linked to P/F, while the influence of inflammation on P/F, reflected by CRP, was also mediated by neutrophils.

In recent decades, several pieces of evidence have drawn greater attention to the topic of innate immunity, in particular, interferon (IFN) and Interleukin 6 in the pathogenesis of idiopathic inflammatory myopathies (IIM). Both of these molecules transduce their signal through a receptor coupled with Janus kinases (JAK)/signal transducer and activator of transcription proteins (STAT). In this review, we discuss the role of the JAK/STAT pathway in IIM, evaluate a possible therapeutic role for JAK inhibitors in this group of diseases, focusing on those with the strongest IFN signature (dermatomyositis and antisynthetase syndrome).

OBJECTIVES:Systemic sclerosis (SSc) is an autoimmune disease characterised by diffuse vasculopathy and fibrosis of skin and visceral organs. Moreover, autonomic dysfunction is also suggested as an important step during the multifactorial SSc pathogenesis. Baroreceptors are responsible for maintaining blood pressure by means of autonomic system modulation. Considering that autonomic dysfunction and arteriosclerosis can both reduce baroreceptor sensitivity (BRS), in this cross-sectional study we investigated BRS in SSc patients.METHODS:Twenty-one SSc patients (mean age 55±10 years, 18 females) and 147 age/sex-matched healthy controls were recruited for the study. BRS (ms/mmHg) was measured by a Finapres® Midi device (Finapres Medical Systems, Amsterdam, The Netherlands). Other parameters were measured: blood pressure, heart rate, heart rate variability triangular index (HRVI), intima-media thickness (IMT), carotid distensibility and pulse wave velocity (PWV).RESULTS:BRS was significantly lower in SSc patients compared to controls (6.3±3.3 vs. 10.7±6.8 ms/mmHg; p=0.004). IMT was comparable between SSc and controls, whereas carotid distensibility was lower in SSc (20.1±7.6 vs. 26.6±13.3 KPa-1·10-3; p=0.02) and PWV higher in SSc (8.4±1.3 vs. 7.1±1.1 m/sec; p=0.01). Furthermore, HRVI was lower in SSc (4.5±2.1 vs. 7.5±2.8; p<0.001). BRS impairment was independent from age and carotid distensibility in SSc patients, suggesting that BRS dysfunction could be only partially a consequence of SSc vasculopathy.CONCLUSIONS:BRS was reduced in SSc patients compared with healthy controls. This finding could represent a SSc-related alteration involving the autonomic system, besides being the mere consequence of sclerodermic vasculopathy.

Background Systemic sclerosis (SSc) is a chronic autoimmune disease that is characterized by vasculopathy and fibrosis of the skin and visceral organs. Heart valve diseases are poorly described and generally not considered typical of SSc. We aimed to describe valvular abnormalities in a multicenter cohort of SSc patients and to investigate their correlation with SSc features. Methods We recruited 118 consecutive SSc patients (male/female, 14/104; mean age, 55.2 +/- 12.1 years) in 3 rheumatology centers in Sicily, Italy, from January to October 2019. Results Mitral and tricuspid valve insufficiency was found in 85% and 91% of patients, respectively; regurgitations were generally mild and never severe. Mitral stenosis was rare (2%), and tricuspid stenosis was not observed. Sclerosis and calcification were present in 30% of mitral valves and in only 4% of tricuspid valves. The aortic valve was affected in 25% of cases, and it generally presented as regurgitation or sclerosis, whereas stenosis was rare (3%). Finally, 11% of SSc patients showed regurgitation of the pulmonary valve. No specific associations between SSc features and valve alterations were found. Conclusions Valvular diseases are frequently observed in SSc patients, with a predominant pattern of valvular regurgitations. Therefore, echocardiography should be routinely performed during SSc patient follow-up, considering the potential influence of additional cardiac involvement in the prognosis of these patients.

Objective: Autoimmune systemic diseases (ASD) represent a predisposing condition to COVID-19. Our prospective, observational multicenter telephone survey study aimed to investigate the prevalence, prognostic factors, and outcomes of COVID-19 in Italian ASD patients. Method: The study included 3,918 ASD pts (815 M, 3103 F; mean age 59±12SD years) consecutively recruited between March 2020 and May 2021 at the 36 referral centers of COVID-19 and ASD Italian Study Group. The possible development of COVID-19 was recorded by means of a telephone survey using a standardized symptom assessment questionnaire. Results: ASD patients showed a significantly higher prevalence of COVID-19 (8.37% vs. 6.49%; p< 0.0001) but a death rate statistically comparable to the Italian general population (3.65% vs. 2.95%). Among the 328 ASD patients developing COVID-19, 17% needed hospitalization, while mild-moderate manifestations were observed in 83% of cases. Moreover, 12/57 hospitalized patients died due to severe interstitial pneumonia and/or cardiovascular events; systemic sclerosis (SSc) patients showed a significantly higher COVID-19-related death rate compared to the general population (6.29% vs. 2.95%; p=0.018). Major adverse prognostic factors to develop COVID-19 were: older age, male gender, SSc, pre-existing ASD-related interstitial lung involvement, and long-term steroid treatment. Of note, patients treated with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) showed a significantly lower prevalence of COVID-19 compared to those without (3.58% vs. 46.99%; p=0.000), as well as the SSc patients treated with low dose aspirin (with 5.57% vs. without 27.84%; p=0.000). Conclusion: During the first three pandemic waves, ASD patients showed a death rate comparable to the general population despite the significantly higher prevalence of COVID-19. A significantly increased COVID-19- related mortality was recorded in only SSc patients’ subgroup, possibly favored by preexisting lung fibrosis. Moreover, ongoing long-term treatment with csDMARDs in ASD might usefully contribute to the generally positive outcomes of this frail patients’ population.

OBJECTIVES:The classification interstitial pneumonia with autoimmune features (IPAF) includes patients with interstitial lung disease (ILD) associated with autoimmune characteristics insufficient to reach classification criteria for a specific autoimmune disease (SAD). These criteria are divided into three domains: clinical, serological and morphological. The latter domain does not include the usual interstitial pneumonia (UIP) pattern, which is deemed not to be significantly associated with SAD. Therefore, the enrolment of these patients is more difficult, requiring at least one item from both of the other domains. The objective of this study is to evaluate the rate of progression towards SAD of a cohort of UIP patients satisfying only one IPAF domain (we called this group "UIPAF") compared with classic idiopathic pulmonary fibrosis (IPF).METHODS:We prospectively enrolled IPF patients with radiologic and/or histologic UIP pattern, followed jointly by rheumatologists and pulmonologists from January 2017 to January 2021, with a minimum follow-up of 12 months.RESULTS:We enrolled 190 IPF patients, 38 (20%) of whom were classified as UIPAF. IPF and UIPAF patients were similar for general characteristics, severity and prognosis, at presentation and at annual check-up. However, 28.9% of UIPAF patients progressed towards SAD, compared with 2% of IPF patients (χ2=30.4, p≤0.0001).CONCLUSIONS:The association between a single clinical or serological domain of IPAF and UIP pattern is predictive for the development of a SAD if compared with isolated UIP. ILD can be the first manifestation of SAD, even with a UIP pattern, therefore, the morphological domain of IPAF criteria could be removed.
