RESUMEN
OBJECTIVE: To evaluate the progression of coronary artery calcification (CAC) and associated risk factors in a systemic lupus erythematosus (SLE) cohort. METHODS: We reassessed the presence of CAC in patients with SLE who were screened 9 years before, using multidetector computed tomography. Clinical variables (cumulated disease activity and damage accrual), antiphospholipid syndrome and SLE serology, and cardiovascular (CV) risk factors (hypertension, BMI [kg/m2], modified Framingham risk score, lipid profile, menopausal status) were assessed longitudinally. RESULTS: We included 104 patients from the parent study. Most of them were women (94.2%), with a mean age of 41.0 (SD 8.3) years and mean disease duration of 14.8 (SD 2.9) years. We documented CAC in 17 patients (16.3%). Seven cases were from the parent study and 10 were incident cases. The cumulative incidence of CAC was 9% and the incidence density was 1 per 100 person-years. CAC occurred more frequently in the age groups 30-39 years and 40-44 years. All patients with previous CAC had worsening of their calcium indexes, and none developed clinical CV events. When comparing prevalent CAC cases (n = 17) vs patients without calcification (n = 87), both groups were similar in traditional CV risk factors, disease duration, Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) area under the curve (AUC), and Systemic Lupus International Collaborating Clinics (SLICC) score, but were more likely to be postmenopausal and have higher apolipoprotein B (apoB) levels. Patients with previous CAC had higher apoB levels, SLEDAI-2K AUC scores, and anticardiolipin IgG antibodies than incident cases. CONCLUSION: CAC in patients with SLE progressed over time but was not associated with adverse CV events during the first 9 years of follow-up. ApoB levels and postmenopausal status might be associated with this progression.
RESUMEN
OBJECTIVES: We aimed to evaluate the prevalence of non-criteria clinical features in patients with primary antiphospholipid syndrome (APS), and to assess their relationship to thrombosis and damage. METHODS: We retrospectively included 177 primary APS patients, and/or patients who only achieved the serological Sydney criteria but had thrombocytopenia and/or haemolytic anaemia. We registered demographics, serology, treatment, thrombotic/obstetric manifestations and non-criteria clinical manifestations (cutaneous, haematologic, renal, heart valve disease, and neurological). We scored the DIAPS and a modified SLICC index. We used logistic regression and reported OR with 95% CI. RESULTS: 78% were women with a median follow-up of 6.7 years. Thrombosis was found in 74% of patients, 29.3% had obstetric features, and 64% had non-criteria clinical manifestations. The frequency of the non-criteria clinical manifestation was: haematologic 40.1%, cutaneous 20.9%, neurologic 18%, cardiac 5% and renal 4.5%. Non-criteria features were associated with LA (OR 2.3, 95% 1.03-5.1) and prednisone use (OR 8.2, 95% CI 1.7-39.3). A DIAPS score ≥1 was associated with thrombosis (OR 53.1, 95% CI 17.8-15.2), prednisone use (OR 0.27, CI 95% 0.09-0.83) and neurological involvement (OR 6.4, 95% CI 1.05-39.8); whereas a modified SLICC ≥ 1 with thrombosis (OR 10.2; IC 95% 4.43-26.1), neurological involvement (OR 6.4, 95%CI 1.05-39.8), obstetric features (OR 0.32 CI 95% 0.12-0,81) and cutaneous features (OR 5.3, CI 95% 1.4-19), especially livedo reticularis (OR 5.45; IC 95% 1.49-19.8). CONCLUSIONS: Non-criteria clinical manifestations are common and associated with LA. Among them, neurologic involvement and the presence of livedo were associated with damage accrual.

OBJECTIVES: To evaluate whether the grade of IgG4+ plasma cell infiltration in biopsies is associated with clinical or serologic outcomes in IgG4-RD. METHODS: We included 57 patients with biopsy proven IgG4-RD according to the Comprehensive Diagnostic Criteria and/or the 2019 ACR/EULAR Classification Criteria. We collected histological, clinical (disease duration, phenotype, remission and relapses) and serological variables. RESULTS: 29 (50.9%) patients were men, mean age 49.9 years, with a median disease duration of 22 months. The distribution among clinical phenotypes were 14% pancreato-hepato-biliary, 12.3% retroperitoneal/aortic, 29.8% head and neck-limited, 29.8% Mikulicz/systemic and 14% undefined. Thirty-nine patients had a proliferative and 18 a fibrotic phenotype. Most biopsies were from lacrimal gland, lymph node, pancreas, orbit, kidney, retroperitoneum and thyroid gland. Thirty-nine (68.4%) patients had <100 IgG4+ plasma cells/HPF and 18 (31.6%) ≥100 IgG4+ plasma cells/HPF. Patients with ≥100 IgG4+ plasma cells/HPF were more likely to belong to the pancreato-hepato-biliary and the proliferative phenotypes, had fewer relapses and a higher remission rate. On multivariate analysis, the OR for remission at last follow-up was 6.7, 95% CI 1.1-4.42, p=0.03. The log-rank test showed a difference in relapse-free survival between the two groups (HR 2.6, 95% CI 1.2-5.6, p=0.01). According to the ROC analysis, patients with more than 61 IgG4+ plasma cells were less likely to relapse. CONCLUSIONS: A count of ≥100 IgG4+ plasma cells/HPF may identify patients with a proliferative phenotype, fewer relapses and a higher remission rate.
RESUMEN
ABSTRACT: A 65-year-old woman presented with unexplained weight loss, recurrent fever, and a dermatosis with painful nodules on the extremities. Biopsies showed focal lobular panniculitis with neutrophilic microgranulomas. Comprehensive investigations ruled out infection and hematologic and solid organ neoplasms. Laboratory results showed anti-Ro/SSA and anti-La/SSB antibody positivity, and elevated inflammatory markers. Dry mouth and eye were confirmed. The diagnosis of Sjögren syndrome with cutaneous panniculitis was established. Prednisone treatment with 30 mg/d resulted in remission of fever and pain improvement. This case emphasizes Sjögren syndrome as an autoimmune disease with multiple cutaneous manifestations and highlights its association with granulomatous panniculitis.

BACKGROUND/OBJECTIVE: The 2019 American College of Rheumatology/European League Against Rheumatism Classification Criteria (2019 AECC) for IgG4-related disease (IgG4-RD) is considered a significant advancement in the study of this condition. Most studies evaluating their performance have focused on White and Asian patients, leaving a knowledge gap regarding Latin American populations. Therefore, this study aimed to assess the performance of the 2019 AECC for IgG4-RD in a cohort of Latin American patients. METHODS: A multicenter medical records review study was conducted, involving centers from Argentina, Chile, Mexico, Peru, and Uruguay. Data on IgG4-RD patients and mimicker conditions were collected through a standardized online form. The criterion standard for diagnosing IgG4-RD was based on the fulfillment of the Comprehensive Diagnostic Criteria for IgG4-RD and/or the Consensus Statement on Pathology. The 2019 AECC was retrospectively applied. RESULTS: We included 300 patients, with 180 (60%) having IgG4-RD and 120 (40%) having mimicker conditions. The 2019 AECC had a sensitivity of 66.7% and a specificity of 100%. Sensitivity increased to 73.3% when disease-specific autoantibody items were removed, without affecting specificity. The true-positive cases had more involved organs, a higher availability of biopsy results, and were more likely to belong to the Mikulicz/systemic and proliferative phenotypes. CONCLUSIONS: The use of the 2019 AECC for IgG4-RD in a Latin American population confirms its high specificity in excluding those without the disease. The presence of concomitant autoimmune diseases and clinically nonsignificant disease-specific autoantibodies excludes a significant number of patients from fulfilling the criteria.

OBJECTIVES: To describe the taxonomy of the microbiota in crevicular fluid of primary Sjögren's syndrome (pSS) patients, and evaluate its association with clinical/serological variables, and oral quality of life. METHODS: Observational study that included 48 pSS without diabetes mellitus, no active neoplasia, no antibiotic use in the previous two weeks, and no current active infection. We registered demographics, oral/ocular sicca symptoms, parotid enlargement and anti-Ro/La serology. We assessed the non-stimulated whole salivary flow (NSWSF), the EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI), and the Xerostomia-related Quality of Life Scale (XeQoLS). Two periodontists determined the presence of periodontal disease and collected crevicular fluid from 6 teeth using filter paper. Samples were frozen at -86°C until processing. We included 17 sex- and age-matched control subjects. Bacterial DNA was extracted from the crevicular fluid sample using a commercial kit. 16SrRNA V3-V4 region was sequenced using reversible adaptor technology. Sequences were pre-processed and analysed using QIIME2 and phyloseq software programs. Functionality profiles were predicted using the Tax4Fun2 package. RESULTS: PSS patients had more bacteria of the genera Prevotella, Streptococcus, Veillonella, Fusobacterium, and Leptotrichia and fewer bacteria of the genus Selenomonas than controls. The pSS microbiota contained more genes encoding accessory secretory proteins. Microbiota also differed between patients with anti-Ro/La status, parotid gland enlargement, and periodontal disease severity, but did not correlate with NSWSF and XeQoLS. CONCLUSIONS: The crevicular fluid microbiota of pSS patients and controls differed significantly, even in SSP patients depending on their serology, parotid gland enlargement, and periodontal disease status.

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 assess the prevalence of parotid gland swelling (PGS) and its association with features of SS and other causes of sialadenosis in a Latin-American cohort of primary SS. METHODS: We included 668 patients from Argentina, Brazil, Mexico and Paraguay. We retrospectively registered demographics, disease duration, oral/ocular symptoms, serology and scored the basal ESSDAI. We defined PGS as a recurrent or persistent increase of volume of any parotid glands during adulthood (self-reported and/or physical examination). We registered the presence of diabetes mellitus, dyslipidaemia, body mass index and alcohol consumption. We used logistic regression analysis reporting odds ratio (OR) and 95% CI. RESULTS: PGS was present in 242 patients (36.2%): 78 previous to SS diagnosis, 86 concomitantly, 73 during follow-up and five unknown. At the multivariate analysis, PGS was associated with RF (OR 2.47, 95% CI: 1.1, 6.5, P = 0.0001), basal articular ESSDAI domain (OR 1.63, 95% CI: 1.01, 2.6, P = 0.04) and alcohol consumption (OR 2.42, 95% CI: 1.41, 4-15). Patients with PGS during the follow-up had a higher prevalence of alcohol consumption (45.3%) compared with the remaining PGS cases (26.8%; OR 2.41 95% CI: 1.2, 4.7), or patients without parotid gland swelling (15.6%; OR 3.8 95% CI: 1.7, 8.2) in all the adjusted models. CONCLUSION: PGS generally precedes or presents concomitantly with SS diagnosis, and is related to RF and articular activity. Alcohol consumption is an additional factor in PGS, especially during follow-up. The meaning of this last finding as well as its prognostic implications remains to be elucidated and deserves further evaluation in prospective studies.

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 evaluated the total body water (TBW) among patients with primary Sjögren's syndrome (pSS) and assess its correlation with the severity of oral and ocular sicca symptoms, and some objective sicca variables. METHODS: We included 85 patients and 85 controls matched by sex, age, and body mass index (BMI). We assessed the Schirmer-I test and the non-stimulated whole salivary flow (NSWSF). We evaluated ocular and oral symptoms during the past 15 days using a 0-10 visual analogue scale (VAS) (highest score=worst symptoms). We obtained the TBW by bioelectric impedance analysis. RESULTS: 80% were women (mean age 54.8 years and mean disease duration 11.5 years). TBW was similar in pSS and controls (46.8±4.6 vs. 46.9±4.5, p=0.88). TBW correlated with age (ρ=-0.25, p=0.02), disease duration (ρ=-0.30, p=0.005), BMI (ρ=-0.78, p=0.001) and ocular VAS scale (ρ=-0.28, p=0.01); but not with NSWSF, Schirmer test or oral VAS scale. When comparing patients in the lowest TBW percentile (≤25%) with the remaining patients, the former group was older, had longer disease duration, higher BMI, lower frequency of anti-Ro/SSA and antinuclear antibodies, and higher ocular VAS scores. In the multivariate analysis, the ocular VAS score (OR 1.88, 95% CI 1.08-3.2, p=0.02) and the BMI 1.92 (OR 1.4, 95% CI 1.4-2.66, p=0.0001) remained associated with a lower TBW percentage. CONCLUSIONS: Patients with pSS had similar TBW percentages to control subjects. However, lower TBW percentages in the pSS were associated with higher BMI and also with the most severe ocular symptoms.

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.

Introduction: The objectives of this study were to compare the quality-of-care and compliance with medical record regulations between in-person consultations (QIP and CIP) and telephone consultations (QTP and CTP), from rheumatoid arthritis (RA) outpatients, during the COVID-19 pandemic, and to explore the impact of the consultation modality on the treatment. Methods: Data from 324 medical notes corresponding to rheumatic consultations between July and December 2020 were abstracted. Notes were selected considering a stratified (in-person and telephone consultations) random sampling strategy. QIP, CIP, QTP, and CTP were scored based on prespecified criteria as percentages, where higher numbers translated into better standards. Logistic regression analysis investigated the association between the consultation modality and the treatment recommendation (dependent variable). Results: There were 208 (64.2%) medical notes related to in-person consultations and 114 (35.2%) to telephone consultations. Overall, medical notes corresponded to middle-aged women with long-standing disease. QIP was superior to QTP (median, interquartile range): 60% (60-75%) versus 50% (25-60%), p ≤ 0.001, and differences were related to disease activity and prognosis documentation (81.3% vs. 34.5% and 55.8% vs. 33.6%, respectively, p ≤ 0.001) and the prolonged prescription of glucocorticoids with a documented management plan (58.5% vs. 30.4%, p = 0.045). Meanwhile, CIP and CTP were similar. Telephone consultation was a significant risk factor for no changes in the treatment recommendation (odds ratio: 2.113, 95% confidence interval: 1.284-3.479, p = 0.003), and results were consistent in the 142 medical notes with documented absence of disease activity. Conclusions: In the clinical context of RA, the quality-of-care provided by telephone consultations is below the standard of care and impacts the treatment.

BACKGROUND: The tendency of IgG4-related disease (IgG4-RD) to form pseudotumors, as well as its multisystemic nature, makes it the perfect mimicker of many conditions. Moreover, some clinical, serological, radiological, or histological features of the disease might be shared with some mimickers.Recently, 4 clinical phenotypes have been identified, and patients grouped in each phenotype have distinctive demographic, clinical, and serological features and outcomes, and, as expected, for each phenotype, a set of differential diagnoses should be considered. SUMMARY OF THE LITERATURE: The main differential diagnoses for the pancreato-hepato-biliary phenotype are pancreatic adenocarcinoma and cholangiocarcinoma. Other differential diagnoses include type 2 autoimmune pancreatitis and primary sclerosing cholangitis. In patients with retroperitoneal/aortic phenotype, inflammatory conditions such as idiopathic retroperitoneal fibrosis and large vessel vasculitides should be ruled out, and most of the time, a biopsy will be needed to exclude malignancies. In head and neck limited phenotype, autoimmune conditions (eg, granulomatosis with polyangiitis, Graves orbitopathy, sarcoidosis), malignancies, and histiocytosis should be ruled out, whereas the main differential diagnoses of the Mikulicz/systemic phenotype are Sjögren syndrome, granulomatosis with polyangiitis, and multicentric Castleman disease. CONCLUSIONS: Approaching a patient with probable IgG4-RD through a clinical phenotype framework will ease the diagnostic algorithm and facilitate the prompt recognition of the disease. There are certain clinical, serological, radiological, and histological features in each clinical phenotype that, if present, increase the likelihood that a patient may have IgG4-RD instead of the mimicker condition. Those clues that point toward IgG4-RD diagnosis should be actively sought in the workup of patients.

BACKGROUND/OBJECTIVE: Data on IgG4-related disease (IgG4-RD) come almost exclusively from cohorts from Asia, Europe, and North America. We conducted this study to describe the clinical presentation, phenotype distribution, and association with sex, ethnicity, and serological markers in a large cohort of Latin American patients with IgG4-RD. METHODS: We performed a multicenter medical records review study including 184 Latin American IgG4-RD patients. We assigned patients to clinical phenotypes: group 1 (pancreato-hepato-biliary), group 2 (retroperitoneal/aortic), group 3 (head and neck-limited), group 4 (Mikulicz/systemic), and group 5 (undefined). We focused the analysis on how sex, ethnicity, and clinical phenotype may influence the clinical and serological presentation. RESULTS: The mean age was 50.8 ± 15 years. Men and women were equally affected (52.2% vs 48.8%). Fifty-four patients (29.3%) were assigned to group 1, 21 (11.4%) to group 2, 57 (30.9%) to group 3, 32 (17.4%) to group 4, and 20 (10.8%) to group 5. Male sex was associated with biliary tract (odds ratio [OR], 3.4; 95% confidence interval [CI], 1.36-8.26), kidney (OR, 3.4; 95% CI, 1.28-9.25), and retroperitoneal involvement (OR, 5.3; 95% CI, 1.45-20). Amerindian patients presented more frequently with atopy history and gallbladder involvement. Group 3 had a female predominance. CONCLUSIONS: Latin American patients with IgG4-RD were younger, and men and women were equally affected compared with White and Asian cohorts. They belonged more commonly to group 1 and group 3. Retroperitoneal and aortic involvement was infrequent. Clinical and serological features differed according to sex, ethnicity, and clinical phenotype.

PURPOSE: To evaluate CCL2, CXCL8, and CXCL10 in the tears of patients with Primary Sjögren's syndrome (PSS) and correlate them with ocular symptoms/discomfort and objective ocular tests. METHODS: We studied 21 patients with PSS. A single ophthalmologist, expert in dry eye, examined the patients and assessed tear film breakup time, Schirmer I test, tear meniscus height, Van Bijsterveld staining score and SICCA Ocular Staining Score. We also assessed the ESSPRI and ocular dryness VAS and the Ocular Surface Disease Index (OSDI), a 12-item scale assessing symptoms associated with dry eye disease and their impact on vision (ocular symptoms/discomfort). Tear samples collected with sterile tear flow strips were frozen at -86 °C until testing. After thawing, tears were extracted from the strips. We tested CCL2, CXCL8, and CXCL10 by luminometry. We also included 21 healthy control subjects without a dry eye. RESULTS: CXCL8 levels were similar in patients and controls. PSS patients had lower levels of CXCL10 (472.8 vs. 1652 pg/µL, p = 0.009) and CCL2 (1.08 vs. 9 pg/µL, p = 0.0001) than controls. Patients with worse ocular sicca symptoms/discomfort had the lowest CXCL10 levels (239.3 vs. 646.2 pg/µL, p = 0.02). CCL2 correlated with tear meniscus height (τ = 0.37, p = 0.02) and with OSS (τ = -0.3, p = 0.05). CONCLUSIONS: We found lower levels of CXCL10 and CCL2 in the tears of patients with PSS, associating the former with worse ocular symptoms and the latter with positive ocular target tests.

BLK and BANK1 in primary Sjögren's syndrome (pSS) have scarcely been evaluated and the results are inconclusive. The aim of our study was to determine whether single nucleotide variants (SNVs) located within BLK or BANK1 are associated with susceptibility, clinical and serological features, and smoking in pSS. BLK rs13277113A/G, BANK1 rs10516487G/A and rs3733197G/A were genotyped in 203 cases and 424 controls using a TaqMan® SNP genotyping assay. The BLK rs13277113A allele showed association with pSS under the allelic (OR 1.35, p = 0.02), and recessive (OR 1.83, p = 0.003) model, while, BANK1 rs3733197G/A showed association under the dominant model (OR 2.90, p = 0.043). Interactions between BANK1 and BLK genotypes also showed association (OR 2.36, p < 0.0001). In addition, BLK rs13277113A/G was associated with protection against arthritis and BANK1 rs10516487G/A with both arthritis and keratoconjunctivitis sicca, meanwhile, BANK1 rs3733197G/A was associated with smoking in patients with pSS. This is the first study to describe an association between BLK and susceptibility to pSS in a Latin-American population. Our data also shows a first evidence of association between interactions of BLK and BANK1 in pSS, and association of BLK and BANK1with arthritis, keratoconjunctivitis sicca and smoking in patients with pSS.

OBJECTIVES: To evaluate the prevalence and meaning of antineutrophil cytoplasmic antibodies (ANCA) positivity in a cohort of IgG4-related disease (IgG4-RD). METHODS: We identified patients with ANCA determination from a retrospective cohort of 69 patients with IgG4-RD. ANCA were measured by indirect immunofluorescence microscopy (IIF) and/or proteinase 3 (PR3)-ANCA and MPO-ANCA by ELISA. IIF patterns were classified as perinuclear (P-ANCA), cytoplasmic (C-ANCA) and atypical (X-ANCA). We compared the ANCA-positive vs the ANCA-negative IgG4-RD group. RESULTS: Out of 69 patients, 31 IgG4-RD patients had an ANCA determination. Four patients with concomitant systemic autoimmune diseases were excluded. We found positive ANCA by IIF in 14 (56%) of 25 patients tested. The most common IIF pattern was C-ANCA in eight (57.1%), followed by dual C-ANCA/X-ANCA in four (28.6%) and P-ANCA and dual C-ANCA/P-ANCA in one each (7.1%). Of the 20 patients with ANCA determination by both IIF and ELISA, four have positive ANCA by ELISA (three for MPO-ANCA and one for PR3-ANCA). Of the two patients with only ELISA determination, one was positive for MPO-ANCA. The prevalence of ANCA positivity by ELISA was 22.7% (5 out of 22 patients). ANCA was more frequent in the Mikulizc/systemic phenotype (42.9%) compared with other phenotypes (P = 0.04). ANCA-positive IgG4-RD patients had more frequently lymph node and kidney involvement, high IgG1 levels and erythrocyte sedimentation rate, and positive antinuclear antibodies. CONCLUSION: ANCA are found in a significant number of patients with IgG4-RD and differed from the ANCA-negative group in terms of clinical and serological features.

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.
