Modifications in self-care, quality of life and therapeutic adherence in patients with rheumatoid arthritis during the SARS-CoV-2 pandemic treated by telehealth

Introduction: Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation, causing pain and stiffness in the joints. SARS-CoV-2 increases the clinical vulnerability of the population with RA and has led to the implementation and/or development of telemedicine. Objective: To describe changes in level of therapeutic adherence, quality of life and capacity for self-care agency, during the follow-up period of a group of patients linked to a non-face-to-face multidisciplinary consultation model during the SARS-CoV-2 pandemic. Methodology: Descriptive cohort study (July to October 2020). Description of the level of therapeutic adherence (Morisky Green Test), quality of life (EuroQOL-5-Dimensions-3-Level-version) and self-care capacity (ASA-R Scale) in the context of a telehealth model. A univariate and bivariate analysis was performed (Stata Software, Considered p-value <0.05). Results: Of 71 patients treated under the telehealth model, 85.9% were women, the age range was between 33 and 86 years with a median of 63. The most prevalent comorbidity was arterial hypertension (35.2%). Quality of life did not change during follow-up nor did adherence to treatment, apart from in one item [the patients did not stop taking the medication when they were well (p = 0.029)]. In self-care capacity, there were significant improvements in five dimensions (p < 0.05), without significant differences in the global score. Conclusion: Patients with RA evaluated in the context of telehealth in a period of pandemic did not present significant changes in quality of life, adherence to treatment, or capacity for self-care, and remained close to baseline values when they attended a traditional face-to-face assessment.

INTRODUCCIÓN: La artritis reumatoide (AR) es una enfermedad autoinmune caracterizada por una inflamación crónica que produce dolor y rigidez articular. El SARS-CoV-2 aumenta la vulnerabilidad clínica en pacientes con AR, lo que ha conllevado la implementación o el desarrollo de la telesalud. OBJETIVO: Describir los cambios en el nivel de adherencia terapéutica, la calidad de vida y la capacidad de autocuidado durante el periodo de seguimiento, en un grupo de pacientes con AR vinculados con un modelo de consulta multidisciplinar no presencial, en el curso de la pandemia por SARS-CoV-2. METODOLOGÍA: Estudio de cohorte descriptiva (julio a octubre del 2020). Descripción del nivel de adherencia terapéutica (TEST MORISKY GREEN), calidad de vida (EUROQOL-5-DIMENSIONS-3-LEVEL-VERSION) y capacidad de autocuidado (Escala ASA-R) en el contexto de un modelo de telesalud. Se realizó análisis univariado y bivariado (SOFTWARE Stata®, valor de p considerado <0,05). RESULTADOS: De 71 pacientes atendidos en modalidad de telesalud, el 85,9% fueron mujeres, la mediana de la edad fue de 63 (33-86) anos. La comorbilidad más prevalente fue la hipertensión (35,2%). La calidad de vida no tuvo cambios durante el seguimiento, al igual que la adherencia al tratamiento, excepto en uno de los ítems (los pacientes no dejaron de tomar la medicación cuando se encontraban bien; p = 0,029). En la capacidad de autocuidado hubo mejoras significativas en 5 dimensiones (p < 0,05), sin diferencias significativas en el puntaje global. CONCLUSIÓN: Los pacientes con AR evaluados en el contexto de la telesalud, en un periodo de pandemia, no presentaron cambios significativos en la calidad de vida, la adherencia al tratamiento y la capacidad de autocuidado; se mantuvieron en niveles similares a los valores basales cuando asistían a valoración tradicional presencial.

Adherence to Subcutaneous Anti-Tumour Necrosis Factor Treatment in a Cohort of Patients with Rheumatoid Arthritis Before and After the Implementation of a Comprehensive Care Model.

Purpose: To assess, in a cohort of patients with rheumatoid arthritis (RA) treated with subcutaneous antitumor necrosis factor drugs (anti-TNFs), the levels of treatment adherence before and after implementing a comprehensive care model (CCM). Patients and Methods: An observational study including RA patients under treatment with subcutaneous anti-TNFs (adalimumab, etanercept, and golimumab) selected at convenience was performed; a sample size of 125 patients was calculated. The outcome variable was adherence assessed with the Compliance Questionnaire on Rheumatology (CQR19), measured before and after implementing a CCM. Descriptive and bivariate analyses were performed comparing adherence before and after applying the model (Wilcoxon and McNemar's Chi2 test). For multivariate analysis, a generalized linear model adjusted for covariates was performed, where the difference in the proportion of adherence was the outcome measure. Results: A total of 131 RA patients were followed-up for 24 months; average age was 62 years, and 83.9% were women. The median of DAS28 at the beginning of the follow-up was 2.32, and the HAQ was 0.25. At baseline, 87.8% were adherent; after 24 months, 96.2% were adherent according to CQR19. At the end of follow-up, adherence increased with the three types of anti-TNFs treatment. In a matched model adjusted for clinical variables, the CCM was estimated to produce a 9.4% increase in the total percentage of adherent patients. Additionally, a statistically significant increase of 4.5% in the percentage of adherent patients treated with golimumab compared with etanercept and adalimumab was found. Conclusion: A CCM produced an important increase in the percentage of patients with rheumatoid arthritis adherent to treatment after 24 months of follow-up. It is noteworthy that Golimumab patients were more adherent when compared with other current anti-TNFs treatments.

Vascular Age, Metabolic Panel, Cardiovascular Risk and Inflammaging in Patients With Rheumatoid Arthritis Compared With Patients With Osteoarthritis.

Introduction: The risk of cardiovascular disease (CVD) in patients with rheumatoid arthritis (RA) is 1.5-2 times higher than the general population. The fundamental risk factor for CVD is age, related to alterations at the arterial level. The aim of the study was to compare vascular age (VA) in RA patients under a strict treat-to-target (T2T) strategy with Osteoarthritis (OA) patients without strict follow up and to assess the influence of inflammaging (chronic, sterile, low-grade inflammation related to aging) and metabolic markers on VA. Materials and Methods: This was an analytical cross-sectional study. Patients with RA (under a strict a T2T strategy) and OA patients without strict clinical follow-up were included. Patients with a history of uncontrolled hypertension, CVD, and/or current smoking were excluded. Sociodemographic, physical activity, and toxic exposure data were obtained. Waist-hip ratio and body mass index (BMI) were measured. DAS-28 (RA) and inflammatory markers, lipid profile, and glycaemia were analyzed. Pulse wave velocity (PWV) was measured (oscillometric method, Arteriograph-TensioMed®). VA was calculated based on PWV. Eleven components of inflammaging [six interleukins, three metalloproteinases (MMP), and two tissue inhibitors of metalloproteinases (TIMP)] were evaluated (Luminex® system). Univariate and bivariate analyzes (Mann Whitney U and chi-square) and correlations (Spearmans Rho) were done to compare the two groups. Results: A total of 106 patients (74% women) were included, 52/RA and 54/OA. The mean age was 57 (Interquartile range - IQR 9 years). The BMI, waist circumference, and weight were higher in patients with OA (p < 0.001). RA patients had low disease activity (DAS-28-CRP). There were no differences in VA, inflammaging nor in PWV between the two groups. VA had a positive, but weak correlation, with age and LDL. In group of RA, VA was higher in those who did not receive methotrexate (p = 0.013). LDL levels correlated with MMP1, TIMP1, and TIMP2. Conclusions: When comparing RA patients with low levels of disease activity with OA patients with poor metabolic control, there are no differences in VA. Furthermore, methotrexate also influences VA in RA patients. This shows that implemented therapies may have an impact on not only the inflammatory state of the joint but also CVD risk.

Safety and efficacy of convalescent plasma for severe COVID-19: a randomized, single blinded, parallel, controlled clinical study.

BACKGROUND: Convalescent plasma (CP) has been widely used to treat COVID-19 and is under study. However, the variability in the current clinical trials has averted its wide use in the current pandemic. We aimed to evaluate the safety and efficacy of CP in severe coronavirus disease 2019 (COVID-19) in the early stages of the disease. METHODS: A randomized controlled clinical study was conducted on 101 patients admitted to the hospital with confirmed severe COVID-19. Most participants had less than 14 days from symptoms onset and less than seven days from hospitalization. Fifty patients were assigned to receive CP plus standard therapy (ST), and 51 were assigned to receive ST alone. Participants in the CP arm received two doses of 250 mL each, transfused 24 h apart. All transfused plasma was obtained from "super donors" that fulfilled the following criteria: titers of anti-SARS-CoV-2 S1 IgG ≥ 1:3200 and IgA ≥ 1:800 antibodies. The effect of transfused anti-IFN antibodies and the SARS-CoV-2 variants at the entry of the study on the overall CP efficacy was evaluated. The primary outcomes were the reduction in viral load and the increase in IgG and IgA antibodies at 28 days of follow-up. The per-protocol analysis included 91 patients. RESULTS: An early but transient increase in IgG anti-S1-SARS-CoV-2 antibody levels at day 4 post-transfusion was observed (Estimated difference [ED], - 1.36; 95% CI, - 2.33 to - 0.39; P = 0.04). However, CP was not associated with viral load reduction in any of the points evaluated. Analysis of secondary outcomes revealed that those patients in the CP arm disclosed a shorter time to discharge (ED adjusted for mortality, 3.1 days; 95% CI, 0.20 to 5.94; P = 0.0361) or a reduction of 2 points on the WHO scale when compared with the ST group (HR adjusted for mortality, 1.6; 95% CI, 1.03 to 2.5; P = 0.0376). There were no benefits from CP on the rates of intensive care unit admission (HR, 0.82; 95% CI, 0.35 to 1.9; P = 0.6399), mechanical ventilation (HR, 0.66; 95% CI, 0.25 to 1.7; P = 0.4039), or mortality (HR, 3.2; 95% CI, 0.64 to 16; P = 0.1584). Anti-IFN antibodies and SARS-CoV-2 variants did not influence these results. CONCLUSION: CP was not associated with viral load reduction, despite the early increase in IgG anti-SARS-CoV-2 antibodies. However, CP is safe and could be a therapeutic option to reduce the hospital length of stay. Trial registration NCT04332835.

Factors Associated With Diagnostic Delay of Axial Spondyloarthritis in Colombian Patients.

BACKGROUND/OBJECTIVE: The diagnostic delay of axial spondyloarthritis (axSpA) is globally reported to be between 3 and 11 years. Early diagnosis and treatment have long-term benefits for patients and the health care system. Several international studies have evaluated some factors associated with diagnostic delay, but there are no known studies in the Colombian population. This study assesses the factors associated with diagnostic delay of axSpA in a rheumatology center in Bogota, Colombia. METHODS: This monocentric analytical cross-sectional study was done in a specialized rheumatology center. Patients who fulfilled the 2009 Assessment of Spondyloarthritis International Society (ASAS) classification criteria for axSpA were included. Information was obtained from medical records and a phone call. Bivariate and multivariate analyses were done to assess the associated factors with diagnostic delay. RESULTS: One hundred one patients were included, 54 were women (53.5%). The median diagnostic delay was 2 years (interquartile range, 1-7). The bivariate analysis showed that a younger age at diagnosis (p = 0.042) and previous diagnosis of lumbar degenerative disease (p = 0.029) were associated with a longer diagnostic delay. The logistical regression showed that previous lumbar degenerative disc disease (odds ratio, 2.8; 95% confidence interval, 1.09-7.53) and fibromyalgia (odds ratio, 4.0; 95% confidence interval, 1.2-13.1) diagnosis were both associated with a longer diagnostic delay. CONCLUSIONS: Factors associated with a longer diagnostic delay were previous diagnosis of lumbar degenerative disc disease and fibromyalgia. Additional studies are needed so that the reasons for diagnostic delay are understood and early diagnosis and management of axSpA are enabled.

Artritis reumatoide y telemedicina en tiempos de COVID-19 / Rheumatoid arthritis and telemedicine in times of COVID-19

La artritis reumatoide es una afección autoinmune, crónica y multisistémica que requiere manejo multidisciplinar, siendo la supervisión continua fundamental para controlar su progresión. Tanto la artritis como el tratamiento generan un estado inmunosupresor que predispone a sufrir infecciones. Por la actual emergencia sanitaria ocasionada por el Sars-Cov2, los pacientes con estas enfermedades crónicas e inmunológicas son más susceptibles de contagio, por ello se ha requerido el uso de nuevas tecnologías como la telemedicina, que en los años previos a la pandemia venía incrementándose su uso, para permitir el control de patologías crónicas. El objetivo del presente estudio es revisar qué implicaciones ha tenido el uso de la telemedicina en el manejo de la artritis reumatoide durante la actual pandemia COVID-19 y cuál ha sido la importancia de la implementación de estas tecnologías en la enfermedad.

Rheumatoid arthritis (RA) is an autoimmune chronic multisystem condition requiring multidisciplinary management. Close follow-up is essential to control its progression. Arthritis and its treatment cause an immunosuppressive status which predisposes to infection. Due to the current health emergency caused by Sars-Cov2, patients affected by chronic and autoimmune disorders are more susceptible to contagion, which has required using new technologies such as telemedicine. The adoption of telemedicine had been increasing since the years prior to the pandemic, to allow assessment of chronic conditions. The aim of this study is to examine the impacts of the use of telemedicine in the management of patient living with RA during the COVID-19 pandemic and the importance of the implementation of these technologies to assist in the care of RA patients.

[SARS-CoV-2 (COVID-19) in Patients with some Degree of Immunosuppression]. / SARS-CoV-2 (COVID-19) en pacientes con algún grado de inmunosupresión.

BACKGROUND: It is not clear whether patients with some degree of immunosuppression have worse outcomes in SARS-CoV-2 infection, compared to healthy people. OBJECTIVE: To carry out a narrative review of the information available on infection by SARS-CoV-2 in immunosuppressed patients, especially patients with cancer, transplanted, neurological diseases, primary and secondary immunodeficiencies. RESULTS: Patients with cancer and recent cancer treatment (chemotherapy or surgery) and SARS-CoV-2 infection have a higher risk of worse outcomes. In transplant patients (renal, cardiac and hepatic), with neurological pathologies (multiple sclerosis [MS], neuromyelitis optica [NMODS], myasthenia gravis [MG]), primary immunodeficiencies and infection with human immunodeficiency virus (HIV) in association with immunosuppressants, studies have shown no tendency for worse outcomes. CONCLUSION: Given the little evidence we have so far, the behaviour of SARS-CoV-2 infection in immunosuppressed patients is unclear, but current studies have not shown worse outcomes, except for patients with cancer.

Human mesenchymal stem cells for the management of systemic sclerosis. Systematic review.

INTRODUCTION: Sistemic Sclerosis (SSc) is a heterogeneous autoimmune disease with a high rate of progression and therapeutic failure, and treatment is a challenge, new therapeutic proposals being needed, being mesenchymal stem cells (MSCs) considered as alternative therapy for SSc for its immunomodulatory capacity. We evaluated the efficacy and safety of human MSC (hMSC) in patients with SSc through a systematic literature review (SLR). METHODS: SLR (PRISMA guideline) on MEDLINE/OVID, LILACS, EMBASE, and Cochrane/OVID bases (until July 2020, without limits). All types of clinical studies were considered: patients ≥18 years old with SSc and treatment with hMSC. EXCLUSION CRITERIA: animal models, autologous/allogenic hematopoietic stem cell transplants, narrative reviews, letters to the editor. MeSH and "Key word" terms were used. The level of evidence and the quality rating were rated [Joanna Briggs Institute (JBI) lists]. Registration in PROSPERO repository (ID CRD42020185245) The Synthesis Without Meta-analysis (SWiM) guideline was followed. RESULTS: We initially identified 508 articles, of which 11 were finally included (8 case series and 3 case reports). The 11 articles included 101 patients (85 female, age range 18-75 years). The level of evidence was mostly 4 (JBI); the quality of evidence was met (≥50% of JBI items). SWiM showed that vascular skin involvement (digital ulcers, necrosis, and gangrene) and associated pain were the predominant outcomes, while improvements were found in almost all cases. One patient died in the first month, and the frequency of complications was low. Expanded hMSCs were used in 24 patients and other cell sources in the remaining patients. CONCLUSION: There is too little reported data to reach definite conclusions about the use of hMSC in SSc. Further studies with better epidemiological designs are needed to evaluate the benefit of hMSCs in SSc patients.

Is there any relationship between massive ascites and elevated CA-125 in systemic lupus erythematosus? Case report and review of the literature.

Systemic lupus erythematosus (SLE) is a chronic, multisystemic autoimmune disease of variable presentation. Massive ascites in the context of SLE is infrequent. Even so, it has been reported that ascites may be the first manifestation of SLE. It is difficult to diagnose due to the multiple possible aetiological causes of ascites. There is a rare entity called Pseudo-Pseudo Meigs Syndrome (PPMS) in patients with SLE who have ascites, pleural effusion, and CA-125 elevation unrelated to malignancy. We present two cases of massive ascites, pleural effusion and elevation of CA-125 with a history of SLE diagnosis. One of these cases was diagnosed with PPMS and another associated with neoplasm of ovarian origin.

ASIA syndrome symptoms induced by gluteal biopolymer injections: Case-series and narrative review.

BACKGROUND: The number of plastic surgery procedures have been rising in the last few years. The morbi-mortality due to illegal use of biopolymers is a public health problem. One of the clinical consequences, foreign body modelling reaction, may be a precursor of ASIA (Autoimmune/Inflammatory disease induced by adjuvants) syndrome.The objective of this article is to present a case-series study of patients who developed ASIA syndrome following gluteal injection with biopolymers and emphasize the importance of toxic exposure in triggering autoimmune responses. A surgical technique used on some of the patients in the study is described. METHODS: A group of thirteen patients, diagnosed with foreign body modelling reaction, who developed ASIA syndrome confirmed by approved criteria was followed between May 2016 and May 2018. The "Butterfly Wings Technique," a new surgical procedure for patients who have medium to severe compromise, was used on five of them.A narrative literature review was done to look for subjects with ASIA syndrome and gluteal biopolymer infiltration. RESULTS: All the patients in the present case-series with foreign body modelling reaction developed ASIA syndrome. Some of them had a background of familial autoimmunity. Five of the patients were surgically treated and saw a clinical improvement after the extraction of the biopolymer with the proposed technique.The narrative literature review identified 7 articles related to the disease through the database search. CONCLUSIONS: We suggest that foreign body modelling reaction should be considered a precursor to ASIA syndrome. New research projects will be needed in the future to evaluate the factors that determine when ASIA syndrome is triggered in a patient with this reaction.

Clinical and sociodemographic factors associated with lupus nephritis in Colombian patients: A cross-sectional study.

INTRODUCTION: Over the past decades, incidence of SLE (Systemic Lupus Erythematosus) has increased due to early case detection and improved survival of patients. SLE presents at an earlier age and has a more severe presentation in African-American, Native American, Asian, and Hispanic populations. Worldwide, lupus nephritis (LN) is observed in 29-60% of SLE patients, it has a negative impact in renal survival and patient mortality. Several cohorts have established potential risk factors associated with lupus nephritis, such as male sex, serological markers, and some extra-renal manifestations. OBJECTIVES: To describe sociodemographic, clinical, immunological, and environmental risk factors in Colombian SLE patients and to compare the population with and without nephritis, in order to establish risk factors and possible associations. MATERIALS AND METHODS: A total of 1175 SLE patients participated in this study. During medical care, an interview and structured survey was conducted and later registered in a database. Sociodemographic, clinical, immunological, and environmental exposure variables were analyzed. Bivariate and multivariate analyses were performed using presence of LN as an outcome. RESULTS: Prevalence of LN was 38.7%. Variables significantly associated with LN included being male (OR 1.98), a duration of SLE>10 years (OR 1.48), positive anti-DNA (OR 1.34), positive anti-Sm (OR 1.45), and smoking (OR 1.66). Being non-smoker was a protective factor (OR 0.52). CONCLUSION: This study describes potential factors associated with lupus nephritis in a Latin American population. Smoking status could be a target for intervention as it is a modifiable risk factor. The association between being male and LN is observed in Latin-American populations such as presented here. Further research in other large-scale population studies and more efforts are needed to gain better insights to explicate these relationships.

Unstimulated whole salivary flow in Sjögren's Syndrome: systematic literature review and meta-analysis

Abstract Background: Sjögren's Syndrome compromises the exocrine function, producing xerostomia and xerophthalmia. It can appear as an isolated condition or associated with other autoimmune diseases (polyautoimmunity). The Unstimulated Salivary Flow rate (UWSF) is used to quantify saliva production. There is no objective evidence to differentiate the values in patients with Sjögren's versus healthy people or patients with non-Sjögren's sicca. The objective of the present review was to evaluate the UWSF in patients with Sjögren's syndrome in comparison to controls (healthy and non-Sjögren's sicca patients). Methods: A systematic literature review was carried out (PRISMA guidelines). Analytical observational studies of cases and controls, cross-sectional studies, cohort studies and randomized clinical trials (including healthy controls) were considered. The Medline/OVID, Lilacs, Embase, and Cochrane/OVID databases were consulted. MeSH, DeCS, keywords, and Boolean operators were used. The meta-analysis (RevMan 5.2) was done through the random-effects model [mean difference (MD)]. Level and quality of evidence were evaluated by the Oxford Center Levels of Evidence and Joanna Brigs list respectively. Results: Thirty-two articles were included (20 were case-control studies,6 were cross-sectional,2 prospective cohort,2 retrospective cohort, and2 studies were abstracts) and 28 were meta-analyzed. The unstimulated whole salivary flow rate in the Sjögren's group was lower than in controls (healthy and patients with non-Sjögren Sicca syndrome) (MD-0.18 ml/min; 95% CI, −0.24 to −0.13; chi2-P-value <0.00001). Heterogeneity was 97% and there was publication bias (funnel plot). The level of evidence was mostly3 or 4. The quality of evidence was met (97% of items valued). Conclusion: For the first time, the unstimulated whole salivary flow rate is found to be lower in patients with Sjögren's syndrome compared to controls (healthy and non-SS sicca) through a meta-analysis.

Ecografía de la glándula salival mayor en pacientes con síndrome seco: descripción de una cohorte colombiana, reporte preliminar / Major salivary gland ultrasound in patients with dry syndrome: Description of a Colombian cohort, and a preliminary report

RESUMEN Introducción: El síndrome de Sjögren (SS) es una enfermedad autoinmune que afecta a las glándulas exocrinas condicionando síndrome seco. Los criterios diagnósticos se basan en pruebas serológicas, oftalmológicas, histopatológicas y flujo salival. Se ha propuesto el uso de la ecografía glandular salival como prueba diagnóstica. Escasos estudios se han realizado en Latinoamérica. Objetivo: Describir las alteraciones ecográficas en las glándulas salivales en una población colombiana que asiste al servicio de reumatología con síntomas secos. Materiales y métodos: Estudio de corte transversal; análisis preliminar de 50 pacientes que asisten por consulta externa (agosto de 2019 a enero de 2020). Evaluación sociodemográfica y clínica a través de cuestionario estructurado, pruebas paraclínicas y oftalmológicas, biopsia de glándula salival menor y valoración ecográfica de las glándulas salivales mayores (puntuación 0-6 basada en De Vita). Análisis univariado y bivariado (Chi-cuadrado y prueba de Fischer). Resultados: El 94% de la población eran mujeres y el 38% tenían SS. El promedio de edad fue de 55,9 ± 9,6 arios. La proporción de pacientes con ecografía positiva para el SS y diagnóstico por criterios del SS es mayor respecto a los pacientes con ecografía negativa (p< 0,0001). Los pacientes con ecografía positiva presentaron mayor proporción de anti-La (p = 0,002), ANA (p = 0,008), anti-Ro (p< 0,0001), linfopenia (p = 0,007), xerostomía objetiva (p = 0,019) y subjetiva (p = 0,041). Conclusiones: La ecografía podría considerarse una herramienta útil en el diagnóstico del SS, dado que los pacientes que presentan alteraciones ecográficas glandulares tienen una mayor proporción de perfil inmunológico positivo (anti-Ro, ANA, anti-La) y su positividad se encuentra asociada al SS por criterios. Se requieren nuevos estudios para evaluar las características operativas de la prueba.

ABSTRACT Introduction: Sjögren's syndrome (SS) is an autoimmune disease affecting the exocrine glands causing dry syndrome. The diagnostic criteria are based on serological, ophthalmological, histopathological, and salivary flow tests. The use of salivary gland ultrasound has been proposed as a diagnostic test. Few studies have been carried out in Latin America. Objective: To describe the ultrasound patterns in the salivary glands in the Colombian population seen in the Rheumatology Department due to dry symptoms. Materials and methods: Cross-sectional study; a preliminary analysis was performed on 50 patients attending the Outpatient Clinic (August-January 2020). A sociodemographic and clinical evaluation was made using a questionnaire. Paraclinical and ophthalmological tests, minor salivary gland biopsy, and ultrasound assessment of the major salivary glands (De Vita score 0-6) were the main items to evaluate. Univariate and bivariate analyses (Chi-squared, Fischer test) were performed. Results: Most (94%) of the population were women, and 38% had SS. The mean age was 55.9±9.6 years old. The proportion of patients with positive ultrasound for SS and a diagnosis using SS criteria was higher compared to patients with negative ultrasound (p<.0001). Patients with positive ultrasound had a higher proportion of anti-La (p=.002), ANAS (p=.008), anti-Ro (p<.0001), lymphopenia (p=.007), and objective and subjective xerostomia (p=.019 and p=.041, respectively). Conclusions: Ultrasound assessment could be considered a useful tool in the diagnosis of SS, since more patients presenting with glandular ultrasound abnormalities have a higher positive immunological profile (anti-Ro, ANAS, anti-La) and their positivity is associated with SS criteria. New studies are required to evaluate the operational characteristics of the test.

Interpretación de la biopsia de glándula salival menor en el síndrome de Sjögren. Correlación clínico-patológica / Interpretation of minor salivary gland biopsy in Sjögren's syndrome. Clinical-pathological correlation

RESUMEN La biopsia de glándula salival menor (BGSM) es uno de los principales criterios (no el único) para el diagnóstico del síndrome de Sjögren, y esto tiene que ir en conjunto con la clínica y los niveles de anticuerpos. Diferentes clasificaciones se han desarrollado para evaluar la interpretación de los hallazgos observados en la BGSM y poder categorizar / diagnosticar el síndrome de Sjögren. Esto ha causado que los patólogos y los clínicos tengan una inadecuada interpretación de la BGSM debido a que existe confusión por las diferentes escalas de puntuación que se han implementado a lo largo del tiempo. El presente artículo de revisión tiene como objetivo ilustrar a la comunidad científica, especialmente reumatólogos, cirujanos orales, internistas y patólogos, entre otros, sobre los hallazgos a considerar en la BGSM al momento del reporte por parte del patólogo.

ABSTRACT The minor salivary gland biopsy (MSBG) is one of the main criteria (not the only one) for the diagnosis of Sjögren's syndrome, and has to be taken in conjunction with the clinic parameters and the antibodies levels. Different classifications have been developed to evaluate the interpretation of the findings observed in the MSBG and to be able to categorise / diagnose Sjögren's syndrome. This has meant pathologists and clinicians have had an unsuitable interpretation of the MSBG due to the existence of confusion due to the different scoring scales that have been implemented over time. This review article aims to illustrate to the scientific community, especially rheumatologists, oral surgeons, internists, and pathologists, among others, on the findings to be considered in the MSBG when reported by the pathologist.

Técnica de recolección del flujo salival no estimulado en el diagnóstico de pacientes con síndrome de Sjögren: unificando conceptos. Una revisión sistemática de la literatura / Unstimulated whole saliva flow collection technique in the diagnosis of patients with Sjögren's syndrome: Unifying concepts. A systematic literature review

RESUMEN El síndrome de Sjögren (SS) es una enfermedad autoinmune que compromete la función de las glándulas exocrinas, produciendo xerostomía y xeroftalmia. El método utilizado para cuantificar la disfunción glandular salival es el flujo salival no estimulado (FSNE). Describir las principales técnicas de recolección del FSNE en pacientes con SS. Revisión sistemática de la literatura (guías PRISMA) de estudios observacionales tipo casos y controles, cohorte y corte transversal que incluyeran pacientes con síntomas secos y diagnóstico de SS por criterios clasificatorios internacionales, que fueran comparados con una población de referencia sana o con síntomas secos no Sjögren y en los cuales se reportara la técnica y el valor del FSNE como desenlace principal. Para la calificación del nivel y calidad de la evidencia se utilizaron las guías Oxford y el Joanna Briggs Institute. Veintinueve artículos fueron incluidos, con una población total de 2.730 pacientes: 1.397 casos y 1.333 controles. La técnica más frecuentemente reportada fue la de Navazesh por recogida espontánea de drenaje durante 5 min. El punto de corte más frecuentemente encontrado fue 0,1 ml/min. Por primera vez se describen, a través de una revisión sistemática de la literatura, las principales técnicas utilizadas para evaluar el FSNE en individuos con SS cuando se comparan con personas sanas o con síndrome seco no SS, resaltando que es una técnica validada, no invasiva, reproducible y de bajo costo.

ABSTRACT Introduction: Sjögren's syndrome (SS) is an autoimmune disease that compromises the function of exocrine glands, producing xerostomia and xerophthalmia. The method used to quantify saliva gland dysfunction is by unstimulated whole saliva flow (UWSF).To describe the main UWSF techniques in patients with SS. Systematic review of the literature (following PRISMA guidelines) of results that include analytical observational studies of case-control, cohort, and cross-sectional studies that include patients with sicca symptoms and diagnosis of SS by international classification criteria, which were compared with healthy subjects or those with non-Sjögren sicca symptoms, and in which the technique and the value of the UWSF was reported as the main outcome. Qualification of the level and quality of the evidence was obtained using the Oxford and Joanna Briggs Institute guidelines. A total of 29 articles were included, with total population of 2,730 patients: 1,397 cases and 1,333 controls. The most frequently reported technique was that of Navazesh by spontaneous drainage collection for 5 min. The most frequent cut-off point found was 0.1ml/min. For the first time in the literature, and by using a systematic review of the literature, a description is presented of the main techniques used to evaluate UWSF in individuals with SS when compared with healthy people or with sicca non-SS syndrome, highlighting that it is a valid, non-invasive, reproducible, and low cost technique.

Síndrome de Sjögren y evaluación de la calidad de vida / Sjögren's syndrome and quality of life assessment

RESUMEN Introducción: El síndrome de Sjögren (SS) es una enfermedad autoinmune, con compromiso multisistémico, especialmente de la función de las glándulas exocrinas. Los pacientes cursan con una alta carga de la enfermedad que compromete su calidad de vida, asociado sobre todo a fatiga crónica, ansiedad, depresión y disfunción sexual, entre otras dificultades. Objetivo: Describir las generalidades de las principales escalas (específicas y no específicas) para la evaluación de la calidad de vida en pacientes con SS. Métodos: Se realizó una revisión narrativa y ampliada de la literatura. Se hizo una búsqueda en las diferentes bases de datos (PubMed, Embase, Cochrane, BVS) y de literatura gris, seleccionando los artículos relacionados con el tema y realizando una extracción de datos de estos. Resultados: Se encontraron 3 escalas realizadas específicamente para pacientes con SS: Sjögren's Syndrome Patient Reported Index, Psychometric Testing of the Primary Sjögren's Syndrome Quality of Life Questionnaire y Profile of Fatigue and Discomfort, y 14 escalas realizadas en el contexto de otras enfermedades (no específicas), utilizadas en pacientes con SS. Conclusiones: Como en otras afecciones, en pacientes con SS es importante la evaluación de la calidad de vida. A tal efecto se cuenta con múltiples escalas, a parte de las 3 citadas, elaboradas específicamente para este tipo de pacientes, sin dejar de lado las escalas no específicas, como el Beck Depression Inventory y el Ocular Surface Disease Index, que tienen su mayor utilidad en la evaluación específica de síntomas asociados a esta enfermedad. Resultados: Se encontraron 3 escalas realizadas específicamente para pacientes con SS: Sjögren's Syndrome Patient Reported Index, Psychometric Testing of the Primary Sjögren's Syndrome Quality of Life Questionnaire y Profile of Fatigue and Discomfort, y 14 escalas realizadas en el contexto de otras enfermedades (no específicas), utilizadas en pacientes con SS.

ABSTRACT Introduction: Sjögren's syndrome (SS) is an autoimmune disease, with multisystemic invol- vement, particularly compromising the function of exocrine glands. The patients have a high burden of the disease associated with chronic fatigue, anxiety, depression, sexual dysfunction, among others. Objective: To describe the generalities of the main scales (specific and non-specific) for the evaluation of quality of life in patients with SS. Methods: A narrative review and expanded review was performed, including a search conducted in the different databases (PubMed, Embase, Cochrane, VHL) and grey literature. Articles related to the topic were selected and data extracted from them. Results: Three scales were developed specifically for patients with SS, and included Sjögren's Syndrome Patient Reported Index, Psychometric Testing of the Primary Sjögren's Syndrome Quality of Life Questionnaire, and Profile of Fatigue and Discomfort, and 14 scales performed in context of other diseases (non-specific) used in patients with SS. Conclusions: As is the case in other diseases, it is important to evaluate the quality of life in patients with SS. There are multiple scales for this evaluation, including the 3 scales mentioned before, specifically developed for these types of patients. The non-specific scales worth noting are, the Beck Depression Inventory and the Ocular Surface Disease Index, having their greatest use in the specific evaluation of symptoms associated with this disease.
