RESUMEN
OBJECTIVES: To analyse how the potential exposure to air pollutants can influence the key components at the time of diagnosis of Sjögren's phenotype (epidemiological profile, sicca symptoms, and systemic disease). METHODS: For the present study, the following variables were selected for harmonization and refinement: age, sex, country, fulfilment of 2002/2016 criteria items, dry eyes, dry mouth, and overall ESSDAI score. Air pollution indexes per country were defined according to the OECD (1990-2021), including emission data of nitrogen and sulphur oxides (NO/SO), particulate matter (PM2.5 and 1.0), carbon monoxide (CO) and volatile organic compounds (VOC) calculated per unit of GDP, Kg per 1000 USD. RESULTS: The results of the chi-square tests of independence for each air pollutant with the frequency of dry eyes at diagnosis showed that, except for one, all variables exhibited p-values <0.0001. The most pronounced disparities emerged in the dry eye prevalence among individuals inhabiting countries with the highest NO/SO exposure, a surge of 4.61 percentage points compared to other countries, followed by CO (3.59 points), non-methane (3.32 points), PM2.5 (3.30 points), and PM1.0 (1.60 points) exposures. Concerning dry mouth, individuals residing in countries with worse NO/SO exposures exhibited a heightened frequency of dry mouth by 2.05 percentage points (p<0.0001), followed by non-methane exposure (1.21 percentage points increase, p=0.007). Individuals inhabiting countries with the worst NO/SO, CO, and PM2.5 pollution levels had a higher mean global ESSDAI score than those in lower-risk nations (all p-values <0.0001). When systemic disease was stratified according to DAS into low, moderate, and high systemic activity levels, a heightened proportion of individuals manifesting moderate/severe systemic activity was observed in countries with worse exposures to NO/SO, CO, and PM2.5 pollutant levels. CONCLUSIONS: For the first time, we suggest that pollution levels could influence how SjD appears at diagnosis in a large international cohort of patients. The most notable relationships were found between symptoms (dryness and general body symptoms) and NO/SO, CO, and PM2.5 levels.

OBJECTIVES: To analyse how the key components at the time of diagnosis of the Sjögren's phenotype (epidemiological profile, sicca symptoms, and systemic disease) can be influenced by the potential exposure to climate-related natural hazards. METHODS: For the present study, the following variables were selected for harmonisation and refinement: age, sex, country, fulfilment of 2002/2016 criteria items, dry eyes, dry mouth, and overall ESSDAI score. Climate-related hazards per country were defined according to the OECD and included seven climate-related hazard types: extreme temperature, extreme precipitation, drought, wildfire, wind threats, river flooding, and coastal flooding. Climatic variables were defined as dichotomous variables according to whether each country is ranked among the ten countries with the most significant exposure. RESULTS: After applying data-cleaning techniques and excluding people from countries not included in the OECD climate rankings, the database study analysed 16,042 patients from 23 countries. The disease was diagnosed between 1 and 3 years earlier in people living in countries included among the top 10 worst exposed to extreme precipitation, wildfire, wind threats, river flooding, and coastal flooding. A lower frequency of dry eyes was observed in people living in countries exposed to wind threats, river flooding, and coastal flooding, with a level of statistical association being classified as strong (p<0.0001 for the three variables). The frequency of dry mouth was significantly lower in people living in countries exposed to river flooding (p<0.0001) and coastal flooding (p<0.0001). People living in countries included in the worse climate scenarios for extreme temperature (p<0.0001) and river flooding (p<0.0001) showed a higher mean ESSDAI score in comparison with people living in no-risk countries. In contrast, those living in countries exposed to worse climate scenarios for wind threats (p<0.0001) and coastal flooding (p<0.0001) showed a lower mean ESSDAI score in comparison with people living in no-risk countries. CONCLUSIONS: Local exposure to extreme climate-related hazards plays a role in modulating the presentation of Sjögren across countries concerning the age at which the disease is diagnosed, the frequency of dryness, and the degree of systemic activity.

OBJECTIVE: To determine in a historical inception cohort the impact of lupus nephritis at disease onset in short-term accrual 2019 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) domains. The possible association with treatment and damage was also investigated. METHODS: One hundred thirty-three consecutive adult systemic lupus erythematosus patients according to the 2019 EULAR/ACR criteria were divided according to the presence (RENAL-lupus) or absence of renal involvement (NONRENAL-lupus) at disease onset. The 2019 EULAR/ACR score and Systemic Lupus International Collaborating Clinics/ACR (SDI) were longitudinally evaluated over 3 years. RESULTS: RENAL-lupus (n = 49 [36.8%]) and NONRENAL-lupus (n = 84 [63.2%]) were similar regarding age ( p = 0.704), female sex ( p = 0.313), and black race ( p = 0.506). At study entry, RENAL-lupus had higher 2019 EULAR/ACR total domains (30 [12-42] vs. 22 [10-36], p < 0.001) and used more often glucocorticoid ( p < 0.001), mycophenolate mofetil ( p = 0.007), and cyclophosphamide ( p = 0.001). After 3 years, a stable number of domain scores was observed for the RENAL-lupus (30 [12-42] vs. 30 [12-42], p = 0.125), whereas an increase was observed for the NONRENAL-lupus (22 [10-36] vs. 23 [10-40], p < 0.001) compared with baseline. Accordingly, RENAL-lupus patients had a lower frequency of additional domains (3/49 [6.1%] vs. 37/84 [44.0%], p < 0.0001). New kidney involvement occurred in 15 (44.1%) of 34 patients of the NONRENAL-lupus. Both groups evolved with a comparable increase in frequency of patients with damage (SDI ≥1) at the end of the study (23/49 [46.9%] vs. 34/89 [40.54%], p = 0.585) with a similar median of SDI (1 [0-4] vs. 0 [0-2], p = 0.132). CONCLUSIONS: The distinct pattern of accrual 2019 EULAR/ACR domains in patients with and without nephritis at disease onset suggests that close surveillance for additional organ involvement, including kidney, is mandatory in NONRENAL lupus in the first 3 years of disease. The unexpected comparable early damage in both groups despite milder disease and less intense immunosuppression in NONRENAL lupus reinforces the need for new and tailored therapies for these patients.

OBJECTIVE: To analyse the safety, immunogenicity and factors affecting antibody response to Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) vaccination in patients with SSc. METHODS: This is a phase 4 prospective study within a larger trial of two doses of inactivated SARS-CoV-2 vaccine (CoronaVac) in 51 SSc patients compared with 153 controls. Anti-SARS-CoV-2-IgG and neutralizing antibodies (NAb) were assessed at each vaccine shot (D0/D28) and 6 weeks after the second dose(D69), only in individuals with negative baseline IgG/NAb and those who did not have coronavirus-19(COVID19) during follow-up. Vaccine safety was also assessed in all participants. RESULTS: Patients and controls had comparable median ages [48(38.5-57) vs 48(38-57) years, P =0.945]. Patients had mostly diffuse SSc (68.6%) and the majority (74.5%) had interstitial lung disease. Most patients were under immunosuppressive therapy (72.5%), mainly MMF (52.9%). After full vaccination (D69), anti-SARS-CoV-2-IgG frequency (64.1% vs 94.2%, P < 0.001) and NAb positivity (53.8% vs 76.9%; P =0.006) were moderate, although lower than controls. The first dose response (D28) was low and comparable for both seroconvertion rates (SC) (P =0.958) and NAb positivity (P =0.537). SSc patients under MMF monotherapy vs other (no therapy/other DMARDs) had lower immunogenicity (SC: 31.3% vs 90%, P < 0.001) and NAb(18.8% vs 85%, P < 0.001). Multiple regression analysis confirmed that MMF use, but not disease subtype, is associated with insufficient seroconversion [odds ratio (OR)=0.056(95% CI: 0.009, 0.034), P =0.002] and NAb positivity [OR = 0.047(95% CI: 0.007, 0.036), P =0.002]. No moderate/severe side-effects were observed. CONCLUSION: CoronaVac has an excellent safety profile and moderate response to anti-SARS-CoV-2 vaccine in SSc. Vaccine antibody response is not influenced by disease subtype and is greatly affected by MMF, reinforcing the need for additional strategies to up-modulate vaccine response in this subgroup of patients.

OBJECTIVES: To evaluate immunogenicity and safety of an inactivated SARS-CoV-2 vaccine in systemic autoimmune myopathies (SAMs) and the possible influence of baseline disease parameters, comorbidities and therapy on immune response. METHODS: This prospective controlled study included 53 patients with SAMs and 106 non-immunocompromised control group (CTRL). All participants received two doses of the Sinovac-CoronaVac vaccine (28-day interval). Immunogenicity was assessed by anti-SARS-CoV-2 S1/S2 IgG seroconversion (SC), anti-S1/S2 IgG geometric mean titre (GMT), factor increase GMT (FI-GMT), neutralizing antibodies (NAb) positivity, and median neutralizing activity after each vaccine dose (D0 and D28) and six weeks after the second dose (D69). Participants with pre-vaccination positive IgG serology and/or NAb and those with RT-PCR confirmed COVID-19 during the protocol were excluded from immunogenicity analysis. RESULTS: Patients and CTRL had comparable sex (P>0.99) and age (P=0.90). Immunogenicity of 37 patients and 79 CTRL-naïve participants revealed at D69, a moderate but significantly lower SC (64.9% vs 91.1%, P<0.001), GMT [7.9 (95%CI 4.7-13.2) vs 24.7 (95%CI 30.0-30.5) UA/ml, P<0.001] and frequency of NAb (51.4% vs 77.2%, P<0.001) in SAMs compared with CTRL. Median neutralizing activity was comparable in both groups [57.2% (interquartile range (IQR) 43.4-83.4) vs 63.0% (IQR 40.3-80.7), P=0.808]. Immunosuppressives were less frequently used among NAb+ patients vs NAb- patients (73.7% vs 100%, P=0.046). Type of SAMs, disease status, other drugs or comorbidities did not influence immunogenicity. Vaccine-related adverse events were mild with similar frequencies in patients and CTRL (P>0.05). CONCLUSION: Sinovac-CoronaVac is safe and has a moderate short-term immunogenicity in SAMs, but reduced compared with CTRL. We further identified that immunosuppression is associated with diminished NAb positivity.

OBJECTIVES: To assess immunogenicity of a heterologous fourth dose of an mRNA (BNT162b2) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine in autoimmune rheumatic diseases (ARD) patients with poor/non-response to inactivated vaccine (Sinovac-CoronaVac). METHODS: A total of 164 ARD patients who were coronavirus disease 2019 (COVID-19) poor/non-responders (negative anti-SARS-CoV-2 S1/S2 IgG and/or neutralizing antibodies-NAb) to the third dose of Sinovac-CoronaVac received an additional heterologous dose of mRNA (BNT162b2) 3 months after last dose. IgG and NAb were evaluated before and after the fourth dose. RESULTS: Significant increases were observed after the fourth dose in IgG (66.4 vs 95.1%, P < 0.001), NAb positivity (5.5 vs 83.5%, P < 0.001) and geometric mean titre (29.5 vs 215.8 AU/ml, P < 0.001), and 28 (17.1%) remained poor/non-responders. Patients with negative IgG after a fourth dose were more frequently under rituximab (P = 0.001). Negative NAb was associated with older age (P = 0.015), RA (P = 0.002), SSc (P = 0.026), LEF (P = 0.016) and rituximab use (P = 0.007). In multiple logistic regression analysis, prednisone dose ≥7.5 mg/day (OR = 0.34; P = 0.047), LEF (OR = 0.32, P = 0.036) and rituximab use (OR = 0.19, P = 0.022) were independently associated with negative NAb after the fourth vaccine dose. CONCLUSIONS: This is the largest study to provide evidence of a remarkable humoral response after the fourth dose of heterologous mRNA SARS-CoV-2 vaccination in ARD patients with poor/non-response to the third dose of an inactivated vaccine. We further identified that treatment, particularly rituximab and prednisone, impaired antibody response to this additional dose.

OBJECTIVE: To characterize 414 patients with primary SS who developed haematological malignancies and to analyse how the main SS- and lymphoma-related features can modify the presentation patterns and outcomes. METHODS: By January 2021, the Big Data Sjögren Project Consortium database included 11 966 patients fulfilling the 2002/2016 classification criteria. Haematological malignancies diagnosed according to the World Health Organization (WHO) classification were retrospectively identified. RESULTS: There were 414 patients (355 women, mean age 57 years) with haematological malignancies (in 43, malignancy preceded at least one year the SS diagnosis). A total of 376 (91%) patients had mature B-cell malignancy, nearly half had extranodal marginal zone lymphoma (MZL) of mucosa-associated lymphoid tissue (MALT lymphoma) (n = 197), followed by diffuse large B-cell lymphoma (DLBCL) (n = 67), nodal MZL lymphoma (n = 29), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) (n = 19) and follicular lymphoma (FL) (n = 17). Rates of complete response, relapses and death were 80%, 34% and 13%, respectively, with a 5-year survival rate of 86.5% after a mean follow-up of 8 years. There were significant differences in age at diagnosis (younger in MALT, older in CLL/SLL), predominant clinical presentation (glandular enlargement in MALT lymphoma, peripheral lymphadenopathy in nodal MZL and FL, constitutional symptoms in DLBCL, incidental diagnosis in CLL/SLL), therapeutic response (higher in MALT lymphoma, lower in DLBCL) and survival (better in MALT, nodal MZL and FL, worse in DLBCL). CONCLUSION: In the largest reported study of haematological malignancies complicating primary SS, we confirm the overwhelming predominance of B-cell lymphomas, especially MALT, with the salivary glands being the primary site of involvement. This highly-specific histopathological scenario is linked with the overall good prognosis with a 5-year survival rate of nearly 90%.

OBJECTIVES: To investigate whether physical activity is associated with enhanced immunogenicity of a SARS-CoV-2 inactivated vaccine (Coronavac) in patients with autoimmune rheumatic diseases (ARD) (n = 898) and in non-ARD (n = 197) individuals without pre-existing immunogenicity to SARS-CoV-2. METHODS: This was a prospective cohort study within an open-label, single-arm, phase 4 vaccination trial. Immunogenicity was assessed after vaccination by measuring seroconversion rates of total anti-SARS-CoV-2 S1/S2 IgG (SC), geometric mean titers of anti-S1/S2 IgG (GMT), factor-increase in GMT (FI-GMT), frequency of neutralizing antibody (NAb), and median neutralizing activity. Physical activity (active being defined as ≥ 150 min/week) and sedentary behavior (>8h/day) were assessed by questionnaire. RESULTS: Physically active ARD patients (n = 494) were younger and less frequently used prednisone/biologics than inactive patients (n = 404). After controlling for covariates, active patients exhibited greater SC (OR: 1.4 [95%CI: 1.1-2.0]), GMT (32% [95%CI: 8.8-60) and FI-GMT (33% [95%CI: 9.6-63%]) vs. inactive. Cluster analysis (physical activity/sedentary status) revealed greater GMT (43.0% [95% CI: 11.0-84.0%) and FI-GMT (48.0% [95%CI: 14.0-92.0%]) in active/non-sedentary vs. inactive/sedentary ARD patients. A dose-response was observed, with greater benefits for the group of patients performing ≥ 350 min/week of physical activity (OR: 1.6 [95%CI: 1.1-2.4]; 41% [95%CI: 10-80%]; 35% [95%CI: 4.3-74], for SC, GMT, and FI-GMT, respectively) vs. the least active group (≤30 min/week). Greater SC (OR: 9.9 [95%CI: 1.1-89.0]) and GMT (26% [95%CI: 2.2-56.0%]) were observed in active vs. inactive non-ARD. CONCLUSIONS: A physically active lifestyle may enhance SARS-CoV-2 vaccine immunogenicity, a finding of particular clinical relevance for immunocompromised patients.

INTRODUCTION: The beneficial effect of hydroxychloroquine (HCQ) in decreasing LDL levels on Systemic Lupus Erythematosus (SLE) is well defined. The influence of this drug on HDL levels is still under debate and information about its effect on cholesterol reverse transport is lacking. OBJECTIVE: To evaluate the effects of HCQ on HDL levels and the transfer of lipids to this lipoprotein in SLE. METHODS: Nineteen SLE patients using only HCQ (SLE WITH HCQ), 19 SLE patients without any therapy (SLE WITHOUT THERAPY), and 19 healthy controls (CONTROL) were included. All three groups were premenopausal women age- and gender-matched. Serum lipids and apolipoproteins were determined by commercial kits. An in vitro transfer of four lipids (14C-Phospolipid, 3H-Cholesteryl ester, 3H-Triglyceride, and 14C-Unesterified cholesterol) from a radioactively labeled nanoemulsion donor to HDL was performed in all participants. RESULTS: Groups had comparable mean age, weight, height, BMI(body mass index), and waist circumference (p > .05). Mean HDL levels were higher in SLE WITH HCQ group compared to SLE WITHOUT THERAPY(58.37 ± 14.04 vs 49.79 ± 8.0 mg/dL; p < .05) but lower than CONTROL (58.37 ± 14.04 vs 68.58 ± 9.99 mg/dL; p < .05). Total cholesterol (TC) and LDL levels were also significantly lower in SLE WITH HCQ compared SLE WITHOUT THERAPY(148.16 ± 16.43 vs 167.11 ± 30.18 mg/dL; p < .05, 75.05 ± 22.52 vs 96.05 ± 25.63 mg/dL; p < .05) and CONTROL (148.16 ± 16.43 vs 174.11 ± 23.70 mg/dL; p < .05, 75.05 ± 22.52 vs 88.53 ± 20.24 mg/dL; p < .05). The in vitro lipid transfer to HDL study revealed a significant difference among the three groups (p = .002) with a higher transfer of unesterified cholesterol(UC) in SLE WITH HCQ compared to SLE WITHOUT THERAPY(5.40 ± 1.05% vs. 4.44 ± 1.05%; p < .05). The latter was significantly decreased compared to CONTROL (5.40 ± 1.05% vs. 5.99 ± 1.71%; p < .05).The percentages of transfer of triacylglycerol (4.93 ± 0.69% vs. 4.50 ± 0.69% vs. 5.14 ± 1.01%; p = .054), esterified cholesterol (5.24 ± 0.70% vs. 4.96 ± 0.89% vs. 5.69 ± 1.27%; p = .079), and phospholipid (15.67 ± 1.03% vs. 15.34 ± 1.44% vs. 16.47 ± 1.89%; p = .066) were similar among groups. CONCLUSION: The present study is the first to demonstrate that HCQ promoted a higher transfer of unesterified cholesterol which may account for the increased HDL levels in lupus patients under HCQ. This desirable effect may underlie the reported reduced atherosclerosis in SLE.

OBJECTIVE: Coronavirus disease 19 (COVID-19) has an increased risk of coagulopathy with high frequency of antiphospholipid antibodies (aPL). Recent reports of thrombosis associated with adenovirus-based vaccines raised concern that SARS-CoV-2 immunization in primary antiphospholipid syndrome (PAPS) patients may trigger clotting complications. Our objectives were to assess immunogenicity, safety, and aPL production in PAPS patients, after vaccinating with Sinovac-CoronaVac, an inactivated virus vaccine against COVID-19. METHODS: This prospective controlled phase-4 study of PAPS patients and a control group (CG) consisted of a two-dose Sinovac-CoronaVac (D0/D28) and blood collection before vaccination (D0), at D28 and 6 weeks after second dose (D69) for immunogenicity/aPL levels. Outcomes were seroconversion (SC) rates of anti-SARS-CoV-2 S1/S2 IgG and/or neutralizing antibodies (NAb) at D28/D69 in naïve participants. Safety and aPL production were also assessed. RESULTS: We included 44 PAPS patients (31 naïve) and 132 CG (108 naïve) with comparable age (p=0.982) and sex (p>0.999). At D69, both groups had high and comparable SC (83.9% vs. 93.5%, p=0.092), as well as NAb positivity (77.4% vs. 78.7%, p=0.440), and NAb-activity (64.3% vs. 60.9%, p=0.689). Thrombotic events up to 6 months or other moderate/severe side effects were not observed. PAPS patients remained with stable aPL levels throughout the study at D0 vs. D28 vs. D69: anticardiolipin (aCL) IgG (p=0.058) and IgM (p=0.091); anti-beta-2 glycoprotein I (aß2GPI) IgG (p=0.513) and IgM (p=0.468). CONCLUSION: We provided novel evidence that Sinovac-CoronaVac has high immunogenicity and safety profile in PAPS. Furthermore, Sinovac-CoronaVac did not trigger thrombosis nor induced changes in aPL production.

OBJECTIVES: Primary Sjögren's syndrome (pSS) is an inflammatory chronic disorder that mainly affects exocrine glands. Additionally, oral infections can aggravate the glandular dysfunction. However, data on primary dental care (PDC) treatment in pSS are scarce. This study aimed to appraise the impact of PDC on the Xerostomia Inventory (XI), unstimulated/stimulated salivary flow rates and salivary cytokine profile in pSS. METHODS: Fifty-two pSS patients and 52 sex- and age-matched control participants without systemic autoimmune diseases were included in a prospective study. At inclusion, all participants were assessed through a standardised protocol, measurement of salivary pro-inflammatory cytokines, and underwent PDC. Dental procedures included: oral hygiene guidance, restorative treatment of caries, surgical removal of residual roots and impacted or partially erupted teeth, cysts, supra and subgingival periodontal scaling and treatment of soft tissue disorders (removal of lesions and treatment of opportunistic infections). After 3 months, the clinical/laboratorial assessments were repeated. RESULTS: At inclusion, the Decayed, Missing and Filled Teeth (DMFT) index was higher in the pSS patients than in the control group (13.3±8.2 vs. 8.6±6.2, p=0.002), whereas periodontal parameters were comparable in both groups (p>0.05). After PDC, 26.9% of pSS patients showed a reduction of at least 6 points (clinical improvement) in XI, but mean XI remained unchanged (p=0.285). PDC resulted in an increase in mean unstimulated (p<0.001) and stimulated (p=0.001) salivary flow rates in pSS, with no change in salivary cytokine profile (p≥0.05). CONCLUSIONS: PDC promoted improvement in unstimulated and stimulated salivary flow rates in pSS. This novel finding reinforces the recommendation of this strategy for pSS patients.

OBJECTIVES: To characterise the key epidemiological, clinical, immunological, imaging, and pathological features of the coexistence between sarcoidosis and Sjögren's syndrome (SS). METHODS: All centres included in two large multicentre registries (the Sjögren Syndrome Big Data Consortium and the Sarco-GEAS-SEMI Registry) were contacted searching for potential cases of coexistence between SS and sarcoidosis seen in daily practice. Inclusion criteria were the fulfilment of the current classification criteria both for SS (2016 ACR/EULAR) and sarcoidosis (WASOG). The following features were considered for evaluating a coexisting immunopathological scenario between the two diseases: non-caseating granulomas (NCG), focal lymphocytic sialadenitis (FLS) and positive anti-Ro antibodies. RESULTS: We identified 43 patients who fulfilled the inclusion criteria (38 women, with a mean age of 53 years at diagnosis of SS and of 52 years at diagnosis of sarcoidosis). In 28 (65%) cases, sarcoidosis was diagnosed concomitantly with SS, or during the follow-up of patients with an already diagnosed SS, while in the remaining 15 (35%), SS was diagnosed during the follow-up of an already diagnosed sarcoidosis. Patients in whom sarcoidosis was diagnosed first showed a lower mean age (43.88 vs. 55.67 years, p=0.005) and were less frequently women (73% vs. 96%, p=0.04) in comparison with those in whom sarcoidosis was diagnosed concomitantly with SS, or during the follow-up of an already diagnosed SS. We identified the following immunopathological scenarios: a combination of NCG involving extrasalivary tissues and anti-Ro antibodies in 55% of patients, a coexistence of both pathological scenarios (extrasalivary NCG and FLS in MSGB) in 42% (with positive anti-Ro antibodies in two thirds of cases), and NCG involving salivary glands and anti-Ro antibodies in 3% of cases. CONCLUSIONS: We have characterised the largest reported series of patients who fulfilled the current classification criteria for both SS and sarcoidosis. This implies that sarcoidosis (and not just the presence of isolated NCG on salivary gland biopsy) may, like other systemic autoimmune diseases, coexist with SS, and that a sarcoidosis diagnosis does not preclude the development of SS in the future.

OBJECTIVES: To investigate the safety and efficacy of SARS-Cov-2 vaccination in patients with primary Sjögren syndrome (pSS) due to scarcity of data in this population. METHODS: By the first week of May 2021, all Big Data SS Consortium centres patients who had received at least one dose of any SARS-CoV-2 vaccine were included in the study. The in-charge physician asked patients about local and systemic reactogenicity to collect SARS-CoV-2 vaccination data. RESULTS: The vaccination data of 1237 patients were received. A total of 835 patients (67%) reported any adverse events (AEs), including local (53%) and systemic (50%) AEs. Subjective symptoms (63%) were the most common local AEs, followed by objective signs at the injection site (16%), and general symptoms were the most commonly reported systemic AEs (46%), followed by musculoskeletal (25%), gastrointestinal (9%), cardiopulmonary (3%), and neurological (2%). In addition, 141 (11%) patients reported a significant worsening/exacerbation of their pre-vaccination sicca symptoms and fifteen (1.2%) patients reported active involvement in the glandular (n=7), articular (n=7), cutaneous (n=6), pulmonary (n=2), and peripheral nervous system (n=1) domains due to post-vaccination SS flares. In terms of vaccination efficacy, breakthrough SARS-CoV-2 infection was confirmed after vaccination in three (0.24 %) patients, and positive anti-SARS-Cov-2 antibodies were detected in approximately 95% of vaccinated SS patients, according to data available. CONCLUSIONS: Our data suggest that patients with pSS develop adequate humoral response and no severe AEs after SARS-CoV-2 vaccination and therefore raise no concerns about the vaccine's efficacy or safety profile in this population.

OBJECTIVE: To analyse the prognosis and outcomes of SARS-CoV-2 infection in patients with primary SS. METHODS: We searched for patients with primary SS presenting with SARS-CoV-2 infection (defined following and according to the European Centre for Disease Prevention and Control guidelines) among those included in the Big Data Sjögren Registry, an international, multicentre registry of patients diagnosed according to the 2002/2016 classification criteria. RESULTS: A total of 51 patients were included in the study (46 women, mean age at diagnosis of infection of 60 years). According to the number of patients with primary SS evaluated in the Registry (n = 8211), the estimated frequency of SARS-CoV-2 infection was 0.62% (95% CI 0.44, 0.80). All but two presented with symptoms suggestive of COVID-19, including fever (82%), cough (57%), dyspnoea (39%), fatigue/myalgias (27%) and diarrhoea (24%), and the most frequent abnormalities included raised lactate dehydrogenase (LDH) (88%), CRP (81%) and D-dimer (82%) values, and lymphopenia (70%). Infection was managed at home in 26 (51%) cases and 25 (49%) required hospitalization (five required admission to ICU, four died). Compared with patients managed at home, those requiring hospitalization had higher odds of having lymphopenia as laboratory abnormality (adjusted OR 21.22, 95% CI 2.39, 524.09). Patients with comorbidities had an older age (adjusted OR 1.05, 95% CI 1.00, 1.11) and showed a risk for hospital admission six times higher than those without (adjusted OR 6.01, 95% CI 1.72, 23.51) in the multivariate analysis. CONCLUSION: Baseline comorbidities were a key risk factor for a more complicated COVID-19 in patients with primary SS, with higher rates of hospitalization and poor outcomes in comparison with patients without comorbidities.

OBJECTIVES: To characterize the phenotypic presentation at diagnosis of childhood-onset primary SS. METHODS: The Big Data Sjögren Project Consortium is an international, multicentre registry using worldwide data-sharing cooperative merging of pre-existing clinical SS databases from the five continents. For this study, we selected those patients in whom the disease was diagnosed below the age of 19 years according to the fulfilment of the 2002/2016 classification criteria. RESULTS: Among the 12 083 patients included in the Sjögren Big Data Registry, 158 (1.3%) patients had a childhood-onset diagnosis (136 girls, mean age of 14.2 years): 126 (80%) reported dry mouth, 111 (70%) dry eyes, 52 (33%) parotid enlargement, 118/122 (97%) positive minor salivary gland biopsy and 60/64 (94%) abnormal salivary US study, 140/155 (90%) positive ANA, 138/156 (89%) anti-Ro/La antibodies and 86/142 (68%) positive RF. The systemic EULAR Sjögren's syndrome disease activity index (ESSDAI) domains containing the highest frequencies of active patients included the glandular (47%), articular (26%) and lymphadenopathy (25%) domains. Patients with childhood-onset primary SS showed the highest mean ESSDAI score and the highest frequencies of systemic disease in 5 (constitutional, lymphadenopathy, glandular, cutaneous and haematological) of the 12 ESSDAI domains, and the lowest frequencies in 4 (articular, pulmonary, peripheral nerve and CNS) in comparison with patients with adult-onset disease. CONCLUSIONS: Childhood-onset primary SS involves around 1% of patients with primary SS, with a clinical phenotype dominated by sicca features, parotid enlargement and systemic disease. Age at diagnosis plays a key role in modulating the phenotypic expression of the disease.

OBJECTIVE: To evaluate if the 2019-European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) criteria at diagnosis of childhood-onset systemic lupus erythematosus (cSLE) are associated with higher rates of early damage scored by Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) Damage Index (SDI). METHODS: This retrospective multicenter study included 670 cSLE patients with ≤5 years of disease duration. All patients fulfilled both 2019-EULAR/ACR and 1997-ACR classification criteria. Total score of 2019-EULAR/ACR criteria and each of its specific domains were assessed at diagnosis as predictors of damage accrual at the last visit, according to the presence of any organ damage (defined by SDI ≥ 1). RESULTS: Median disease duration was 2.8 (IQR 1.8-3.8) years and 200 (29.9%) patients had at least one organ damage (SDI ≥ 1). The most frequent domains were neuropsychiatric (12%), renal (7%), and musculoskeletal (6%). There was a higher frequency of renal (58% vs 43%, p = 0.0004) and neuropsychiatric domain (21% vs 7%, p < 0.0001) of 2019-EULAR/ACR criteria in patients with damage (SDI ≥ 1) compared to those without damage (SDI = 0). Patients scoring renal or neuropsychiatric domains of the 2019-EULAR/ACR criteria at diagnosis were associated with renal damage (odds ratio 9.701, 95% confidence interval 3.773-24.941, p < 0.001) or neuropsychiatric damage (OR 9.480, 95% CI 5.481-16.399, p<0.0001) at latest visit, respectively. cSLE patients with positive anti-dsDNA at diagnosis were also associated with renal damage by the latest visit (OR 2.438, 95% CI 1.114-5.3381, p = 0.021). Constitutional, hematologic, mucocutaneous, serosal, and musculoskeletal domains and specific criteria as well as other immunologic criteria were not associated with damage accrual. Median of SLEDAI-2K was significantly higher in patients with global damage (19.5 (2-51) vs 14 (0-51), p<0.001). 2019-EULAR/ACR score >25 was associated with more overall (SDI ≥ 1) (38% vs 25%, p = 0.0002) and renal damage (11% vs 5%, p = 0.023). CONCLUSIONS: The 2019-EULAR/ACR criteria at diagnosis were associated with a higher rate of early damage in cSLE patients, especially for renal and neuropsychiatric damage. Of note, damage was particularly associated with high disease activity at diagnosis and 2019-EULAR/ACR score >25.

OBJECTIVES: To analyse the frequency and characteristics of post-COVID-19 syndrome in patients with primary Sjögren's syndrome (pSS) affected by acute SARS-CoV-2 infection. METHODS: By the first week of April 2021, all centres included in the Big Data Sjögren Consortium were contacted asking for patients included in the Registry diagnosed with SARSCoV-2 infection according to the ECDC guidelines. According to the NICE definitions, symptoms related to COVID-19 were classified as acute COVID-19 (signs and symptoms for up to 4 weeks), ongoing symptomatic COVID-19 (presence of signs and symptoms from 4 to 12 weeks) and post-COVID-19 syndrome (signs and symptoms that continue for > 12 weeks not explained by an alternative diagnosis after a protocolized study). RESULTS: We identified 132 patients who were followed a mean follow-up of 137.8 days (ranging from 5 days to 388 days) after being diagnosed with COVID-19. In the last visit, 75 (57%) patients remained symptomatic: 68 (52%) remained symptomatic for more than 4 weeks fulfilling the NICE definition for ongoing symptomatic post-COVID-19, and 38 (29%) remained symptomatic for more than 12 weeks fulfilling the definition of post-COVID-19 syndrome. More than 40% of pSS patients reported the persistence of four symptoms or more, including anxiety/depression (59%), arthralgias (56%), sleep disorder (44%), fatigue (40%), anosmia (34%) and myalgias (32%). Age-sex adjusted multivariate analysis identified raised LDH levels (OR 10.36), raised CRP levels (OR 7.33), use of hydroxychloroquine (OR 3.51) and antiviral agents (OR 3.38), hospital admission (OR 8.29), mean length of hospital admission (OR 1.1) and requirement of supplemental oxygen (OR 6.94) as factors associated with a higher risk of developing post-COVID-19 syndrome. A sensitivity analysis including hospital admission in the adjusted model confirmed raised CRP levels (OR 8.6, 95% CI 1.33-104.44) and use of hydroxychloroquine (OR 2.52, 95% CI 1.00-6.47) as the key independent factors associated with an enhanced risk of developing post-COVID-19 syndrome. CONCLUSIONS: This is the first study that analyses the frequency and characteristics of post-COVID-19 syndrome in patients affected by a systemic autoimmune disease. We found that 57% of patients with pSS affected by COVID-19 remain symptomatic after a mean follow-up of 5 months. The risk of developing post-COVID-19 syndrome in patients who required hospitalisation was 8-times higher than in non-hospitalised patients, with baseline raised CRP levels and the use of hydroxychloroquine being independent risk factors for post-COVID-19.

OBJECTIVES: To analyse how the main components of the disease phenotype (sicca symptoms, diagnostic tests, immunological markers and systemic disease) can be driven by the age at diagnosis of primary Sjögren's syndrome (pSS). METHODS: By January 2021, the participant centres had included 12,753 patients from 25 countries that fulfilled the 2002/2016 classification criteria for pSS. The age at diagnosis was defined as the time when the attending physician confirmed fulfilment of the criteria. Patients were clustered according to age at diagnosis. 50 clusters with more than 100 observations (from 27 to 76 years) were used to study the influence of the age at diagnosis in the disease expression. RESULTS: There was a consistent increase in the frequency of oral dryness according to the age at diagnosis, with a frequency of <90% in patients diagnosed at the youngest ages and >95% in those diagnosed at the oldest ages. The smooth curves that best fitted a linear model were the frequency of dry mouth (adjusted R2 0.87) and the frequency of abnormal oral tests (adjusted R2 0.72). Therefore, for each 1-year increase in the age at diagnosis, the frequency of dry mouth increased by 0.13%, and the frequency of abnormal oral diagnostic tests by 0.11%. There was a consistent year-by-year decrease in the frequency of all autoantibodies and immunological markers except for cryoglobulins. According to the linear models, for each 1-year increase in the age at diagnosis, the frequency of a positive result decreased by 0.57% (for anti-Ro antibodies), 0.47% (for RF) and 0.42% (for anti-La antibodies). The ESSDAI domains which showed a more consistent decrease were glandular and lymph node involvement (for each 1-year increase in the age at diagnosis, the frequency of activity decreased by 0.18%), and constitutional, cutaneous, and haematological involvements (the frequency decreased by 0.09% for each 1-year increase). In contrast, other domains showed an ascending pattern, especially pulmonary involvement (for each 1-year increase in the age at diagnosis, the frequency of activity increased by 0.22%), and peripheral nerve involvement (the frequency increased by 0.09% for each 1-year increase). CONCLUSIONS: The influence of the age at diagnosis on the key phenotypic features of pSS is strong, and should be considered critical not only for designing a personalised diagnostic approach, but also to be carefully considered when analysing the results of diagnostic tests and immunological parameters, and when internal organ involvement is suspected at diagnosis.

BACKGROUND/OBJECTIVE: Our aim was to describe the short- and long-term outcome of peripheral neuropathy (PN) attributed exclusively to systemic lupus erythematosus (SLE). METHODS: Systemic lupus erythematosus patients with defined PN (clinical and electroneuromyography) were retrospectively evaluated at onset, 1-year, and 5-year follow-up using a standardized electronic chart database that started in 2000. Exclusion criteria were comorbidities, drugs, and infections. Age-, sex-, and disease duration-matched SLE patients without PN were selected as controls. RESULTS: Lupus PN was identified in 38 (1.8%) of 2074 patients, and almost two thirds had PN onset in the first 5 years of SLE (63.2%). Peripheral neuropathy SLE had higher frequencies of cutaneous vasculitis (50% vs 21.1%, p = 0.002), lymphopenia (60.5% vs 36.8%, p = 0.027), anti-Sm (52.6% vs 27.6%, p = 0.013), and higher SLEDAI-2K scores (11.5 ± 10.5 vs 4.9 ± 6.7, p < 0.001) compared with controls. The most common type was polyneuropathy (71.1%) with sensory-motor pattern (68.4%). At PN diagnosis, all patients received glucocorticoid and 97.4% started immunosuppressive therapy (50% intravenous cyclophosphamide, 42.1% azathioprine). After 1-year follow-up, 92.1% had a favorable outcome with complete (36.8%) or partial remission (55.2%), in parallel with a decrease in prednisone dose (48.3 ± 17.9 vs 15.3 ± 13.4 mg/d, p < 0.001), symptomatic therapy (57.9% vs 29.7%, p = 0.02), and SLEDAI-2K score (11.5 ± 10.5 vs 1.7 ± 3.7, p < 0.001). SLEDAI-2K scores were higher in patients who had PN onset with less than 1 year of SLE duration, compared with those with more than 5 years of disease (21.3 ± 9.1 vs 3.9 ± 5.3, p < 0.001). Early-PN-onset group had a better response to treatment (complete remission at 1-year follow-up 61.5% vs 25%, p = 0.039). At 5-year follow-up, 89.3% remained with complete/partial remission. CONCLUSIONS: Peripheral neuropathy attributed to SLE itself is a rare manifestation with a bimodal pattern, characterized by a predominant early-onset group associated with high disease activity and a higher rate of complete remission, and a late-onset group with low disease activity and a partial therapy response.

OBJECTIVE: To characterize the systemic phenotype of primary Sjögren's syndrome at diagnosis by analysing the EULAR-SS disease activity index (ESSDAI) scores. METHODS: The Sjögren Big Data Consortium is an international, multicentre registry based on worldwide data-sharing cooperative merging of pre-existing databases from leading centres in clinical research in Sjögren's syndrome from the five continents. RESULTS: The cohort included 10 007 patients (9352 female, mean 53 years) with recorded ESSDAI scores available. At diagnosis, the mean total ESSDAI score was 6.1; 81.8% of patients had systemic activity (ESSDAI score ≥1). Males had a higher mean ESSDAI (8.1 vs 6.0, P < 0.001) compared with females, as did patients diagnosed at <35 years (6.7 vs 5.6 in patients diagnosed at >65 years, P < 0.001). The highest global ESSDAI score was reported in Black/African Americans, followed by White, Asian and Hispanic patients (6.7, 6.5, 5.4 and 4.8, respectively; P < 0.001). The frequency of involvement of each systemic organ also differed between ethnic groups, with Black/African American patients showing the highest frequencies in the lymphadenopathy, articular, peripheral nervous system, CNS and biological domains, White patients in the glandular, cutaneous and muscular domains, Asian patients in the pulmonary, renal and haematological domains and Hispanic patients in the constitutional domain. Systemic activity measured by the ESSDAI, clinical ESSDAI (clinESSDAI) and disease activity states was higher in patients from southern countries (P < 0.001). CONCLUSION: The systemic phenotype of primary Sjögren's syndrome is strongly influenced by personal determinants such as age, gender, ethnicity and place of residence, which are key geoepidemiological players in driving the expression of systemic disease at diagnosis.
