RESUMEN
Objectives: The primary aim of the CHANGE survey is to determine the current state of gender equity within rheumatology, and secondarily, to review the physician perspective on bullying, harassment and equipoise of opportunities within rheumatology. Methods: The CHANGE e-survey is a cross-sectional self-reported questionnaire adapted from EULAR's gender equity in academic rheumatology task force. The survey was launched in January 2023; it is available in six languages and distributed widely via rheumatology organizations and social media. Eligible participants include rheumatologist physicians and rheumatology health-care professionals. Survey responses will undergo descriptive analysis and inter-group comparison aiming to explore gender-based discrimination using logistic regression, with subgroup analyses for country/continent variations. Conclusion: This e-survey represents a comprehensive global initiative led by an international consortium, aimed at exploring and investigating the gender-related disparities and obstacles encountered by rheumatologists and rheumatology health-care professionals across diverse communities and health-care environments. By pursuing this initiative, we aim to take the broader rheumatology community a step closer to understanding the underlying origins of inequities and their determinants. Such insights are pivotal in identifying viable interventions and strategies to foster gender equity within the field. Ultimately, our collective objective is to ensure equitable access to opportunities for every individual, irrespective of gender, thereby promoting inclusivity and fairness across the entire spectrum of professional practice and career development.
RESUMEN
OBJECTIVE: This study aimed to establish the association between HLA-A, B, DR genotypes and gastrointestinal variables in patients with SpA without inflammatory bowel disease (IBD). METHODS: Retrospective study of 91 patients with SpA and 401 healthy controls, with typing by Illumina Sequencing/PacBio and LIFECODES HLA-PCR/SSO multiplex sequencing technology. The presence of gastrointestinal symptoms was evaluated by administering a survey, and those who presented 2 or more symptoms were taken for clinical evaluation by rheumatology and gastroenterology, colonoscopy and histopathological study. (Ethics committee approval). RESULTS: The 59,3% of the patients were men, with a mean age of 43,9±11.4 years; 80,2% were classified as ankylosing spondylitis. 14, 28 and 19 genotypes for the HLA-A*, HLA-B* and HLA-DR* loci were identified in both groups, of which a relationship with gastrointestinal symptoms was identified: A*26, A*29 and B*27 were associated to abdominal pain, DRB1*11 and DRB1*16 with abdominal distention, A*30, B*38, DRB1*13 and DRB1*14 with weight loss, B*40 with diarrhea >4 weeks, and presence of mucus in the stools with A*02 and DRB1*11 (p<0.05). Furthermore, the presence of B*15 had a statistical relationship with intolerance to some food, highlighting the B*27 genotype in relation to grains and dairy products, A*23 with grains, vegetables and meats, and B*49 with vegetables and dairy (p<0.05). Regarding the endoscopic variables, macroscopic changes were found in the ileum mucosa related to A*02, B*48, DRB1*14 and the relationship between B*27 and ulcers at this level should be highlighted. Macroscopic changes in the sigmoid colon with B*48 and the rectum with A*30. In microscopic changes, inflammatory alterations of the ileum are mentioned with genotypes DRB1*07, DRB1*13 and DRB1*14, a genotype that is related to changes in the ileum both endoscopically and histologically (p<0.05). CONCLUSIONS: These findings indicate a potential genetic predisposition related to HLA genotypes that may increase the likelihood of food intolerance, gastrointestinal symptoms, and even visible and microscopic changes, specifically in the ileal tissue. The study highlights the presence of B*27 and other noteworthy HLA class I and class II genes (such as DRB1*14) in the diverse Colombian population.
OBJETIVO: Establecer la asociación entre genotipos HLA-A, B, DR y variables gastrointestinales en pacientes con EspA, sin enfermedad inflamatoria intestinal (EII). MÉTODOS: Estudio retrospectivo de 91 pacientes con EspA y 401 controles sanos, con tipificación por tecnología de secuenciación Illumina Sequencing/PacBio, y LIFECODES HLA-PCR/SSO multiplex. Se evaluó la presencia de síntomas gastrointestinales por aplicación de una encuesta, y, aquellos que presentaran dos o más síntomas, fueron llevados a valoración clínica por reumatología y gastroenterología, colonoscopia y estudio histopatológico. (Aprobación del Comité de Ética, HMC, 2022 - 2020). RESULTADOS: El 59,3% de los pacientes fueron hombres, con edad media de 43,9 ± 11,4 años. El 80,2% se clasificó como espondilitis anquilosante. Se identificaron en ambos grupos 14, 28 y 19 genotipos para los loci HLA-A*, HLA-B* y HLA-DR*, de los cuales se identificó relación con síntomas gastrointestinales: A*26, A*29 y B*27, con dolor abdominal; DRB1*11 y DRB1*16, con distensión abdominal; A*30, B*38, DRB1*13 y DRB1*14, con pérdida de peso; B*40, con diarrea >4 semanas y presencia de moco en las deposiciones con A*2 y DRB1*11 (p<0,05). Además, la presencia de B*15, tuvo relación estadística con intolerancia a algún tipo de alimento, a resaltar el genotipo B*27, en relación con granos y lácteos; A*23 con granos, verduras y carnes; y el B*49, con verduras y lácteos (p<0,05). Frente a las variables endoscópicas, se encontraron cambios macroscópicos en la mucosa de íleon relacionados con A*02, B*48, DRB1*14 y, a destacar, la relación B*27 con úlceras a este nivel. Cambios macroscópicos en colon sigmoides con B*48 y en recto con A*30. En cambios microscópicos, se mencionan alteraciones inflamatorias de íleon con genotipos DRB1*07, DRB1*13 y DRB1*14, genotipos que se relaciona a cambios en íleon tanto endoscópica e histológicamente (p<0,05). CONCLUSIONES: Estos resultados sugieren una posible susceptibilidad genética asociada al HLA, con genotipos que pueden predisponer a intolerancia alimentaria, síntomas gastrointestinales, e incluso, a cambios macroscópicos e histológicos, particularmente en tejido de íleon, entre los cuales está presente el B*27, pero resaltan otros interesantes en HLA clase I, como clase II (DRB1*14), en una población de alto mestizaje como la colombiana.

OBJECTIVE: The objective is to describe the HLA allelic frequency in PsA and correlate it with demographic and clinical variables. METHODS: Retrospective study of adult patients with a diagnosis of PsA (n=23) and healthy controls (n=46), all with a request for HLA-A, B, C, DR. Typing was performed using HLA-PCR/SSO LifeCodes and analyzed on the LUMINEX IS100/200 xMAP® system. (Ethics/Code HMC2022-014). RESULTS: One hundred thirty-eight alleles were included from 69 individuals, 43,5% women, aged 44,5±16,5 years in patients with PsA, with a mean age of disease onset of 33.4±14 years. Only 9.5% had a high Body Mass Index and dyslipidemia was the most frequent comorbidity (34.8%), followed by high blood pressure (26,1%). 82% debuted with skin manifestation and once the joint disease was established, the predominance was peripheral (74%) due to arthritis/arthralgia in 74%, enthesitis in 30% and dactylitis in 13%. The allele frequencies were for HLA*A 2402 (13%), 3201 (13%) and 2427 (8,7%), for HLA*B 1402 (17,4%), 4002 (17,4%), 3801 (13%) and HLA*DR 0404 (17,4%), 0407 (13%). No HLA*B27 was identified and HLA*C0602 was only 2,2%. HLA A*0201 and DR*1301 were less frequent in controls versus PsA (p=0.024 and 0,029, respectively), while HLA*B1302 was frequent in PsA (p=0,035). CONCLUSIONS: Curiously, there were no positive results for HLAB*27, which may be related to the population mix. HLA Cw6 is traditionally associated with psoriasis. However, its absence has been linked to nail disorders and PsA; consequently, in our study, it had a low frequency (2,2%). On the other hand, HLA*B1302 has been related to the disease and its early onset; in the healthy Colombian population, it has been described in 0,92%; in our group, it is found to be significant in patients without establishing a clinical association. Few previous studies report HLA results in PsA in Colombia.
OBJETIVO: Describir la frecuencia alélica de HLA en APs y asociarlo con variables demográficas y clínicas. MÉTODOS: Estudio retrospectivo de pacientes adultos con diagnóstico de APs (n=23), y controles sanos (n=46), todos con solicitud de HLA-A, B, C y DR. La tipificación se realizó por medio de HLA-PCR/SSO LifeCodes, y se analizó en el sistema LUMINEX IS 100/200 xMAP®. (Ética/Código HMC2022-014). RESULTADOS: Se incluyeron 138 alelos de 69 individuos, 43,5% mujeres, con edad 44,5±16,5 años, en pacientes con APs, con edad media de inicio de la enfermedad de 33,4±14 años. Solo el 9,5% tuvo Índice de Masa Corporal alto y la dislipidemia fue la comorbilidad más frecuente (34,8%), seguida de hipertensión arterial (26,1%). El 82% debutó con manifestación en piel y una vez establecida la enfermedad articular, el predominio fue periférico (74%), por artritis/artralgias en un 74%, entesitis en 30%, y dactilitis 13%. Las frecuencias alélicas fueron para HLA*A 2402 (13%), 3201 (13%) y 2427 (8,7%), para HLA*B 1402 (17,4%), 4002 (17,4%), 3801 (13%) y HLA*DR 0404 (17,4%), 0407 (13%). No se identificó HLA*B27 y HLA*C0602 fue solo del 2,2 %. HLA A*0201 y DR*1301 fueron menos frecuentes en controles versus APs (p=0,024 y 0,029, respectivamente), mientras que HLA*B1302 frecuente en APs (p=0,035). CONCLUSIÓN: Curiosamente no hubo resultados positivos para HLAB*27 y esto puede relacionarse con el mestizaje de la población. HLA Cw6 es tradicionalmente asociado a psoriasis, sin embargo, su ausencia se ha relacionado con mayor reporte de alteraciones ungueales y Aps; como consecuencia, en nuestro estudio tuvo una baja frecuencia (2,2%). Por otro lado, el HLA*B1302 ha tenido relación con la enfermedad y su inicio temprano, en población sana colombiana se ha descrito en 0,92%, en nuestro grupo se encuentra de manera significativa en los pacientes sin establecerse asociación clínica. Pocos estudios previos refieren resultados de HLA en APs en Colombia.

OBJECTIVE: To compare the diversity and composition of the gastrointestinal microbiome of patients with SpA. METHODS: MiSeq sequencing of the V3-V4 region of the 16S ribosomal RNA gene was performed on DNA isolated from stool. Patients with concurrent SpA and IBD were excluded. Differences were assessed for richness and diversity indices by QIIME 2™. Differences between means >0,2% with a p-value<0,05 were assumed significant. Institutional Ethics Committee endorsement. RESULTS: 69 individuals included, 49 with SpA (ankylosing spondylitis-AS 72,9%, psoriatic arthritis-PsA 18,8%, reactive arthritis-ReA 8,3%) 5 positive controls-dysbiosis and 15 controls-eubiosis. Conventional treatment in 42,9%, anti-IL-17 16,3% and anti-TNF 40,8%. By subtype, statistically significant differences in favour of AS were found for the diversity indices. AS vs PsA there was a difference in favour of AS for Clostridium clostridioforme (p=0,002), Gemmiger formicilis (p=0,009), Roseburia inulivorans (p=0,008) and Lachnospira pectinoschiza. AS vs ReA there was a difference in favour of AS for L. pectinoschiza (p=0,009), Ruminococcus callidus (p=0.006), Clostridium ruminantium (p=0.031); G. formicilis (p=0,034). Diversity and richness showed differences in patients with high activity for Simpson's and Pielou's indices. In high activity, lower enrichment of Bacteroides eggerthii (p= 0,0003), C. ruminantium (p= 0,026) and Alistipes putredinis (p=0,035) was found. The number of ASV was higher in the anti-IL-17 vs conventional group (p=0.025) and a trend between anti-IL-17 vs anti-TNF (p=0.09). In anti-TNF there was a lower proportion for C. clostridioforme (p=0.023), G. formicilis (p=0.030) and R. callidus (p= 0.003). In anti IL-17, Alistipes indistinctus (p= 0.012) was decreased. CONCLUSIONS: There are differences in microbial diversity for SpA subtypes. The level of disease activity is plausible to influence the composition of the faecal microbiota. Anti-TNFα treatment may influence the microbiome environment favouring restoration of the gut microbiota, while anti-IL-17 may maintain an inflammatory environment.
OBJETIVO: Comparar la diversidad y composición del microbioma gastrointestinal de pacientes con EspA. MÉTODOS: La secuenciación MiSeq de la región V3-V4 del gen ARN ribosomal 16, se realizó en ADN aislado de heces. Se excluyeron pacientes con EspA y EII simultánea. Se evaluaron diferencias para los índices de riqueza y diversidad por medio de QIIME 2™. Las diferencias entre medias> 0,2%, con un valor de p< 0,05, se asumieron significativas. Aval del Comité de Ética Institucional. RESULTADOS: 69 individuos incluidos, 49 con EspA (espondilitis anquilosante-EA 72,9%, artritis psoriásica-APs 18,8%, artritis reactiva-ARe 8,3%), cinco controles positivos-disbiosis y 15 controles-eubiosis. El tratamiento convencional en 42,9%, anti-IL-17 16,3%, y anti-TNF 40,8%. Por subtipo-EasP, se encontraron diferencias estadísticamente significativas a favor de EA para los índices de diversidad. Entre EA vs APs, hubo diferencia a favor de EA para Clostridium clostridioforme (p=0,002), Gemmiger formicilis (p=0,009), Roseburia inulivorans (p=0,008) y Lachnospira pectinoschiza. Entre EA vs ARe hubo diferencia a favor de EA para L. pectinoschiza (p=0,009), Ruminococcus callidus (p = 0,006), Clostridium ruminantium (p=0,031); G. formicilis (p=0,034). La diversidad y riqueza mostraron diferencias en pacientes con alta actividad para los índices de Simpson y Pielou. En alta actividad, se encontró menor enriquecimiento de Bacteroides eggerthii (p=0,0003), C. ruminantium (p= 0,026) y Alistipes putredinis (p= 0,035). El número de ASV fue superior en el grupo de anti IL-17 vs convencional (p=0.025), y una tendencia entre anti IL-17 vs anti-TNF (p=0,09). En anti TNF hubo menor proporción para C. clostridioforme (p=0,023), G. formicilis (p=0,030) y R. callidus (p= 0,003). Y en anti IL-17, Alistipes indistinctus (p= 0,012), estuvo disminuida. CONCLUSIONES: Existen diferencias en la diversidad microbiana para los subtipos de EspA. El nivel de actividad de la enfermedad es plausible para influir en la composición de microbiota fecal. El tratamiento con anti-TNFα, puede influenciar el ambiente del microbioma favoreciendo la restauración de la microbiota intestinal, mientras los anti IL-17 podrían mantener un ambiente inflamatorio.

OBJECTIVE: Psoriatic arthritis (PsA) is chronic disease that compromises multiple domains and might be associated with progressive joint damage, increased mortality, functional limitation, and considerably impaired quality of life. Our objective was to generate evidence-based recommendations on the management of PsA in Pan American League of Associations for Rheumatology (PANLAR) countries. METHODS: We used the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE)-ADOLOPMENT approach to adapt the 2019 recommendations of the European Alliance of Associations for Rheumatology. A working group consisting of rheumatologists from various countries in Latin America identified relevant topics for the treatment of PsA in the region. The methodology team updated the evidence and synthesized the information used to generate the final recommendations. These were then discussed and defined by a panel of 31 rheumatologists from 15 countries. RESULTS: Theses guidelines report 15 recommendations addressing therapeutic targets, use of antiinflammatory agents and corticosteroids, treatment with disease-modifying antirheumatic drugs (conventional synthetic, biologic, and targeted synthetic), therapeutic failure, optimization of biologic therapy, nonpharmacological interventions, assessment tools, and follow-up of patients with PsA. CONCLUSION: Here we present a set of recommendations to guide decision making in the treatment of PsA in Latin America, based on the best evidence available, considering resources, medical expertise, and the patient's values and preferences. The successful implementation of these recommendations should be based on clinical practice conditions, healthcare settings in each country, and a tailored evaluation of patients.

INTRODUCTION: Psoriatic arthritis is a chronic inflammatory pathology that generates a substantial and progressive deterioration of functionality and quality of life. It is associated with comorbidities (cardiovascular and metabolic) and involvement of mental health. In Latin America, information regarding the disease is limited. This study reviews the burden of disease (disease activity, functional involvement, clinical manifestations, comorbidities, patient-reported outcomes, quality of life, and use of health resources) in PsA patients in Latin America. METHODS: Systematic literature review of publications in PUBMED, EMBASE, Cochrane Database of Systematic Reviews-CDSR/Database of Abstracts of Reviews of Effects, LILACS, Scielo, Redalyc, conference abstracts, and grey literature. Two independent assessors selected studies and extracted information. Quality was assessed according to the type of study. RESULTS: We identified 692 references, selecting 50 studies: 41 cross-sectional, four economic-studies, four cohort studies and one systematic review. The information comes mainly from Brazil, Argentina, and Mexico. The estimated disease prevalence for Latin America ranges from 0.004 to 0.08% (95% CI 0.02-0.20). Measurements with validated instruments suggest suboptimal assessment of disease domains, significant functional compromise, loss of productivity, and high frequency of comorbidities, including mental health. Methodological and population considerations limit the generalizability of the findings. CONCLUSIONS: The available information reports a considerable burden of disease in patients with PsA in Latin America, with involvement of quality of life associated with disability in relation to disease activity and its various manifestations. Future research and funding efforts should be aimed at generating more standardized information about the impact of PsA in the region. Key Points â¢The functional involvement related to disease activity, the impact on the quality of life, and the frequency of cardiometabolic and psychological comorbidities are remarkable in Latin American patients with PsA. â¢The current synthesis offers an overview of the burden of disease (disease activity, functional involvement, clinical manifestations, comorbidities, patient-reported outcomes, quality of life, and use of health resources) in PsA patients in Latin America. â¢Future research efforts and clinical strategies are required in order to generate standardized data on the patients and better estimate the burden of disease in the region.

Axial spondyloarthritis (axSpA) comprises a spectrum of chronic inflammatory manifestations affecting the axial skeleton and represents a challenge for diagnosis and treatment. Our objective was to generate a set of evidence-based recommendations for the management of axSpA for physicians, health professionals, rheumatologists and policy decision makers in Pan American League of Associations for Rheumatology (PANLAR) countries. Grading of Recommendations, Assessment, Development and Evaluation-ADOLOPMENT methodology was used to adapt existing recommendations after performing an independent systematic search and synthesis of the literature to update the evidence. A working group consisting of rheumatologists, epidemiologists and patient representatives from countries within the Americas prioritized 13 topics relevant to the context of these countries for the management of axSpA. This Evidence-Based Guideline article reports 13 recommendations addressing therapeutic targets, the use of NSAIDs and glucocorticoids, treatment with DMARDs (including conventional synthetic, biologic and targeted synthetic DMARDs), therapeutic failure, optimization of the use of biologic DMARDs, the use of drugs for extra-musculoskeletal manifestations of axSpA, non-pharmacological interventions and the follow-up of patients with axSpA.

The role of Blastocystis in intestinal health is an open controversy, and little is known about the potential effect of this microorganism in autoinflammatory diseases such as spondyloarthritis (SpA). Here, we analyzed the gut microbiome of 36 SpA patients and 13 control individuals and demonstrated that the richness, diversity, and taxonomic composition between these two groups are different. We also showed that colonization by Blastocystis in control individuals increases the richness and diversity of the intestinal microbiome, whereas in SpA patients, it does not seem to have any impact. This may reflect a potential role of Blastocystis in sculpting the gut microbiome architecture in control individuals, whereas in subjects with SpA, the modulation of the microbiome may be governed by disease-dependent factors that cannot be overcome by Blastocystis. Regarding taxonomic characterization, SpA patients colonized by Blastocystis showed significant increases in the phylum Pseudomonadota, class Gammaproteobacteria, family Succinivibrionaceae, and genus Succinivibrio. Simultaneously, there were significant increases in the class Bacilli, order Lactobacillales, families Lactobacillaceae and Clostridiaceae, and genera Lactobacillus and Clostridium in non-colonized SpA patients. On the other hand, PICRUSt analysis in Blastocystis-positive SpA patients showed elevations in pathways that may enhance antioxidant capacities and alleviate intestinal inflammation, while Blastocystis-negative SpA patients showed significant changes in pathways that promote cell division/proliferation and can lead to larger changes in the gut microbiome. Our analyses lead us to believe that these changes in the gut microbiome of SpA patients may trigger protective mechanisms as an initial response to inflammation in an attempt to restore balance in the intestinal environment.

INTRODUCTION: Porphyromonas gulae have the enzyme PPAD, as P. gingivalis, which is responsible for citrullination related to the pathophysiology of rheumatoid arthritis and periodontitis; this implies the presence of two species of PPAD-producing bacteria in the mouth as well as the presence of citrullinated proteins. There are no previous reports or studies investigating an association between P. gulae PPAD in rheumatoid arthritis (RA). OBJECTIVE: To assess the presence of P. gulae and anti-citrullinated peptide antibodies of P. gulae PAD in patients with RA and their possible relationship with clinical activity markers. SUBJECTS AND METHODS: A total of 95 patients with RA and 95 controls were included. Erythrocyte sedimentation rate (ESR), C-reactive protein, anti-citrullinated protein antibodies (ACPAs) and rheumatoid factor (RF) were measured. Activity index-28 (DAS28) and SCDAI. The periodontal diagnosis was established. Presence of P. gulae and P. gingivalis. An ELISA was used to determine antibodies against citrullinated peptides of P. gulae PAD. RESULTS: A P. gulae frequency of 15.8% was observed in the RA group and 9.5% in the control group. Higher levels of ACPA were found in the P. gulae-positive patients of the RA group, finding no significant difference, but if in patients positive for P. gingivalis with statistical significance (p = 0.0001). The frequency of anti-VDK-cit and anti-LPQ-cit9 antibodies to PPAD of P. gulae was higher in the RA group than in the control group without significant difference. No relationship was found with the clinical variables despite the presence of P. gulae and anti-citrullinated peptide antibodies of P. gulae PPAD in patients with RA CONCLUSIONS: It was not possible to establish a connection with clinical variables in RA and P. gulae; as a result, the presence of P. gingivalis continues to contribute significantly to the increase in antibodies against citrullinated proteins/peptides from exogenous sources of citrullination in RA and periodontitis.

Porphyromonas gingivalis secretes virulence factors like Arg-gingipains and peptidyl arginine deiminase (PPAD), that are associated with rheumatoid arthritis (RA) pathogenesis. However, there is no information regarding the antibody titers for these bacterial enzymes as systemic indicators or biomarkers in RA. In this cross-sectional study, 255 individuals were evaluated: 143 were diagnosed with RA, and 112 were without RA. Logistic regression models adjusted for age, sex, basal metabolic index, smoking, and periodontitis severity were used to evaluate the association of RA with rheumatoid factor (RF), anti-citrullinated protein antibodies (ACPAs), erythrocyte sedimentation rate, high sensitivity C-reactive protein, anti-RgpA, anti-PPAD, and double positive anti-RgpA/anti-PPAD. It was found that RF (odds ratio [OR] 10.6; 95% confidence interval [CI] 4.4-25), ACPAs (OR 13.7; 95% CI 5.1-35), and anti-RgpA/anti-PPAD double positivity (OR 6.63; 95% CI 1.61-27) were associated with RA diagnoses. Anti-RgpA was also associated with RA (OR 4.09; 95% CI 1.2-13.9). The combination of anti-RgpA/anti-PPAD showed a high specificity of 93.7% and 82.5% PPV in identifying individuals with RA. RgpA antibodies were associated with the periodontal inflammatory index in RA individuals (p < 0.05). The double positivity of the anti-RgpA/anti-PPAD antibodies enhanced the diagnosis of RA. Therefore, RgpA antibodies and anti-RgpA/anti-PPAD may be biomarkers for RA.
RESUMEN
Adipokines are associated with the pathogenesis of rheumatoid arthritis (RA) and are potential biomarkers of disease activity, periodontitis, and obesity. The aim of this was to establish the association between adipokine profile, RA disease activity, body mass index, and periodontal infection. This study evaluated 51 patients with early-RA and 51 controls including serum rheumatological markers, adipokine levels, detection of Porphyromonas gingivalis and serum anti-Porphyromonas gingivalis antibodies, clinical and periodontal measurements. Statistical analyses were run with SPSS® V26, with a logistic regression model to confirm associations. The results show high levels of leptin were more frequent in patients (p = 0.001) who simultaneously showed a higher frequency of Porphyromonas gingivalis (p = 0.004). Patients with concomitant presence of Porphyromonas gingivalis, high clinical activity score, and overweight were correlated with high levels of leptin (OR, 7.20; 95% CI, 2.68-19.33; p = 0.0001) and adipsin (OR, 2.69; 95% CI, 1.00-7.28; p = 0.005). The conclusion is that high levels of leptin and adipsin are associated with greater clinical activity in early-RA patients with overweight and periodontal infection, whereby overweight and Porphyromonas gingivalis may enhance RA activity. This may represent a pathological mechanism between these conditions, where adipokines seem to have a key role.
RESUMEN
OBJECTIVES: To investigate factors associated with severe COVID-19 in people with psoriasis (PsO), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA). METHODS: Demographic data, clinical characteristics and COVID-19 outcome severity of adults with PsO, PsA and axSpA were obtained from two international physician-reported registries. A three-point ordinal COVID-19 severity scale was defined: no hospitalisation, hospitalisation (and no death) and death. ORs were estimated using multivariable ordinal logistic regression. RESULTS: Of 5045 cases, 18.3% had PsO, 45.5% PsA and 36.3% axSpA. Most (83.6%) were not hospitalised, 14.6% were hospitalised and 1.8% died. Older age was non-linearly associated with COVID-19 severity. Male sex (OR 1.54, 95% CI 1.30 to 1.83), cardiovascular, respiratory, renal, metabolic and cancer comorbidities (ORs 1.25-2.89), moderate/high disease activity and/or glucocorticoid use (ORs 1.39-2.23, vs remission/low disease activity and no glucocorticoids) were associated with increased odds of severe COVID-19. Later pandemic time periods (ORs 0.42-0.52, vs until 15 June 2020), PsO (OR 0.49, 95% CI 0.37 to 0.65, vs PsA) and baseline exposure to TNFi, IL17i and IL-23i/IL-12+23i (OR 0.57, 95% CI 0.44 to 0.73; OR 0.62, 95% CI 0.45 to 0.87; OR 0.67, 95% CI 0.45 to 0.98; respectively; vs no disease-modifying antirheumatic drug) were associated with reduced odds of severe COVID-19. CONCLUSION: Older age, male sex, comorbidity burden, higher disease activity and glucocorticoid intake were associated with more severe COVID-19. Later pandemic time periods, PsO and exposure to TNFi, IL17i and IL-23i/IL-12+23i were associated with less severe COVID-19. These findings will enable risk stratification and inform management decisions for patients with PsO, PsA and axSpA during COVID-19 waves or similar future respiratory pandemics.

There is little literature on the implementation of screening criteria for inflammatory bowel disease (IBD) in patients with spondyloarthritis (SpA). This study aimed to apply IBD screening criteria in a group of patients with SpA without IBD diagnosis and correlate them to endoscopic findings and disease activity. A total of 82 patients with SpA were included. The IBD screening test and ileocolonoscopy with digital chromoendoscopy with magnification and histological analysis were performed. The data were analysed with Chi-square test/Fisher's exact test and multiple correspondence analysis. The major screening criteria found in 48.7% of the patients were associated with a history of infection (p = 0.037). Rectal bleeding was associated with the diagnosis of ankylosing spondylitis, acute inflammation, enthesitis and tissue architecture alteration in the ileum (p < 0.050). Diarrhoea was associated with a higher disease activity score (p = 0.02). Minor screening criteria were associated with painful inflammatory joint (p = 0.05), high disease activity score (p = 0.001) and high calprotectin levels (p = 0.050). Abdominal pain (36.9%) was associated with axial/peripheral compromise (p = 0.017), inflammatory back pain (p = 0.01), enthesitis (p = 0.021), higher disease activity score (p = 0.023) and acute ileum inflammation (p = 0.046). Diarrhoea of 4 weeks and abdominal pain were the most prevalent major and minor screening criteria, respectively, being related to early manifestations of inflammatory bowel compromise and higher disease activity score. This screening test grants a chance of opportune referral of SpA patients from rheumatology to gastroenterology.

OBJECTIVE: To propose a consensus modification of the HAQ according to the predominant values, language, and culture of the society. METHODS: First, a scoping review of the literature and a survey of HAQ users were conducted to identify the problems of this questionnaire. In a second phase, a meeting was held with expert professionals to discuss the results and design proposals for modification. RESULTS: The scoping review allowed us to describe the main versions of the HAQ, as well as their psychometric properties. The HAQ users survey assessed the degree of comprehension, usefulness, timeliness, and universality of each of the items, and suggestions and opinions on its main limitations were accepted. During the discussion meeting, modifications to the items were proposed based on the results of the scoping review and the users survey. In addition, the difficulty of understanding the items, their difficulty in assessing intended movements, redundancy, obsolescence, and possible gender bias were taken into account. CONCLUSIONS: An update of the Spanish version of the HAQ is proposed based on the literature review and expert opinion that highlights the paradigm shift in cultural values and aims to increase the content validity and discrimination capacity of this questionnaire.

BACKGROUND: Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by joint inflammation and destruction. OBJECTIVE: Establish the association between Porphyromonas gingivalis (P. gingivalis) infection, body mass index (BMI), joint involvement, and serum adipokines in first-degree relatives (FDR) of patients with rheumatoid arthritis (RA). METHODS: The cross-sectional study evaluated 124 FDR and 124 healthy controls (HC). The clinical examination included joint and radiographic evaluation and calculation of BMI. Serum adipokine levels were measured (leptin, vaspin, adiponectin, resistin, and adipsin), as were the erythrocyte sedimentation rate, C-reactive protein, and anti-citrullinated protein antibodies. Investigations were performed to detect P. gingivalis, and anti-P. gingivalis antibodies. Statistical analyses were performed to confirm associations. RESULTS: Leptin levels in FDR were associated with BMI >25 (OR, 2.64; 95%CI, 1.17-5.97; P=0.019), radiographic damage (Simple Erosion Narrowing Score [SENS])/hands, total SENS, and joint space narrowing in feet (P=0.037, 0.026, 0.020, respectively). FDR had more tender joints (P=0.018); this finding was associated with high levels of leptin and resistin and low levels of adipsin (P=0.040, 0.040, and 0.019, respectively). The presence of P. gingivalis was related to FDR, low levels of adipsin, resistin, adiponectin, and a trend toward higher levels of leptin (P=0.002, 0.001, 0.003, and 0.060, respectively), whereas anti-P. gingivalis antibodies were related to low levels of adipsin (P=0.001). CONCLUSION: In FDR, serum adipokine levels were associated with overweight and the presence of P. gingivalis. Adipokine levels were also associated with joint involvement. Hence, adipokines may be involved in the pathogenesis of RA in FDR and warrant further investigation.

OBJECTIVE: We aimed to compile evidence for the efficacy and safety of therapeutic options for the peripheral arthritis domain of psoriatic arthritis (PsA) for the revised 2021 Group in Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) treatment recommendations. METHODS: A working group consisting of clinicians and patient research partners was convened. We reviewed the evidence from new randomized controlled trials (RCTs) for PsA treatment from February 19, 2013, to August 28, 2020. We used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE)-informed approach to derive evidence for the classes of therapeutic options for 3 patient groups: (1) naïve to treatment, (2) inadequate response to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), and (3) inadequate response to biologic DMARDs (bDMARDs). Recommendations were derived through consensus meetings. RESULTS: The evidence review included 69 RCTs. We derived GRADE evidence for each class of therapeutic options and achieved consensus for the recommendations. For patients naïve to treatment, the working group strongly recommends csDMARDs (methotrexate, sulfasalazine, leflunomide) and phosphodiesterase 4 inhibitors, and emphasizes regular assessment and early escalation to achieve treatment target. bDMARDs (tumor necrosis factor inhibitors [TNFi], interleukin 17 inhibitors [IL-17i], IL-12/23i, IL-23i) and Janus kinase inhibitors (JAKi) are also strongly recommended. For patients with inadequate response to csDMARDs, we strongly recommend TNFi, IL-17i, IL-12/23i, IL-23i, and JAKi. For those who had prior experience with bDMARDs, we strongly recommend a second TNFi, IL-17i, IL-23i, and JAKi. The evidence supporting nonpharmacological interventions was very low. An expert panel conditionally recommends adequate physical activity, smoking cessation, and diet to control weight gain. CONCLUSION: Evidence supporting optimal therapy for the peripheral arthritis domain of PsA was compiled for the revised 2021 GRAPPA treatment recommendations.

OBJECTIVES: To define the instruments for the Assessment of SpondyloArthritis international Society-Outcomes Measures in Rheumatology (ASAS-OMERACT) core domain set for axial spondyloarthritis (axSpA). METHODS: An international working group representing key stakeholders selected the core outcome instruments following a predefined process: (1) identifying candidate instruments using a systematic literature review; (2) reducing the list of candidate instruments by the working group, (3) assessing the instruments' psychometric properties following OMERACT filter 2.2, (4) selection of the core instruments by the working group and (5) voting and endorsement by ASAS. RESULTS: The updated core set for axSpA includes seven instruments for the domains that are mandatory for all trials: Ankylosing Spondylitis Disease Activity Score and Numerical Rate Scale (NRS) patient global assessment of disease activity, NRS total back pain, average NRS of duration and severity of morning stiffness, NRS fatigue, Bath Ankylosing Spondylitis Function Index and ASAS Health Index. There are 9 additional instruments considered mandatory for disease-modifying antirheumatic drugs (DMARDs) trials: MRI activity Spondyloarthritis Research Consortium of Canada (SPARCC) sacroiliac joints and SPARCC spine, uveitis, inflammatory bowel disease and psoriasis assessed as recommended by ASAS, 44 swollen joint count, Maastricht Ankylosing Spondylitis Enthesitis Score, dactylitis count and modified Stoke Ankylosing Spondylitis Spinal Score. The imaging outcomes are considered mandatory to be included in at least one trial for a drug tested for properties of DMARD. Furthermore, 11 additional instruments were also endorsed by ASAS, which can be used in axSpA trials on top of the core instruments. CONCLUSIONS: The selection of the instruments for the ASAS-OMERACT core domain set completes the update of the core outcome set for axSpA, which should be used in all trials.

BACKGROUND AND AIMS: Spondyloarthritis (SpA) is a group of autoinflammatory disorders, of which the primary extra-articular manifestation is inflammatory bowel disease (IBD). The oral cavity being a part of gastrointestinal tract, is significantly compromised in IBD, and in many cases, it is the first site of clinical manifestations of IBD. This study aimed to identify changes in the oral mucosa associated with the onset of IBD and their association with endoscopic/histological findings. MATERIALS AND METHODS: The study assessed 80 patients with SpA and 52 healthy controls. Oral, rheumatological, and gastroenterological assessments were performed. The ileocolonoscopy was performed via digital magnification chromoendoscopy. The statistical analysis consisted of Chi-square, Fisher's exact, and multiple correspondence discriminant analysis tests. RESULTS: From the disease cohort, 63.0% patients showed oral lesions (p = 0.050). These manifestations ranged from gingivitis (55.0%, p = 0.001), aphthous stomatitis (3.8%, p = 0.091), angular cheilitis (2.6%, p = 0.200), and perioral erythema with scaling (1.3%, p = 0.300). All patients who presented with alterations in colonic mucosa also had oral lesions associated with IBD (p = 0.039), specifically gingivitis/aphthous stomatitis (p = 0.029). CONCLUSION: The patients with SpA without IBD present significant oral signs and symptoms. Gingivitis seems to be the most relevant because of its associations with early endoscopic and histological findings. CLINICAL RELEVANCE: An integral approach to the diagnostic tests that includes evaluations of oral, rheumatological and gastroenterological tissues may favor timely attention and improve patients' quality of life.
