RESUMO

AIM: The soluble scavenger receptor differentiation antigen 163 (sCD163), a monocyte/macrophage activation marker, is related to cardiovascular mortality in the general population. This study aimed to evaluate their relationship between serum levels of sCD163 with cardiovascular risk indicators in rheumatoid arthritis (RA). METHODS: A cross-sectional study was performed on 80 women diagnosed with RA. The cardiovascular risks were determined using the lipid profile, metabolic syndrome, and QRISK3 calculator. For the assessment of RA activity, we evaluated the DAS28 with erythrocyte sedimentation rate (DAS28-ESR). The serum levels of sCD163 were determined by the ELISA method. Logistic regression models and receiver operating characteristics (ROC) curve were used to assess the association and predictive value of sCD163 with cardiovascular risk in RA patients. RESULTS: Levels of sCD163 were significantly higher in RA patients with high sensitivity protein C-reactive to HDL-c ratio (CHR)≥0.121 (p=0.003), total cholesterol/HDL-c ratio>7% (p=0.004), LDL-c/HDL-c ratio>3% (p=0.035), atherogenic index of plasma>0.21 (p=0.004), cardiometabolic index (CMI)≥1.70 (p=0.005), and high DAS28-ESR (p=0.004). In multivariate analysis, levels of sCD163≥1107.3ng/mL were associated with CHR≥0.121 (OR=3.43, p=0.020), CMI≥1.70 (OR=4.25, p=0.005), total cholesterol/HDL-c ratio>7% (OR=6.63, p=0.044), as well as with DAS28-ESR>3.2 (OR=8.10, p=0.008). Moreover, levels of sCD163 predicted CHR≥0.121 (AUC=0.701), cholesterol total/HDL ratio>7% (AUC=0.764), and DAS28-ESR>3.2 (AUC=0.720). CONCLUSION: Serum levels of sCD163 could be considered a surrogate of cardiovascular risk and clinical activity in RA.

RESUMO

INTRODUCTION: Systemic lupus erythematosus (SLE) is an autoimmune with variable severity, common in Hispanic and African-American individuals. OBJECTIVE: To know the clinical activity and the accumulated damage, as well as the prevalence and incidence, in a dynamic cohort of patients with SLE from the Yucatan Peninsula (1995-2016). PATIENTS AND METHODS: A cohort of 200 patients with SLE, medical service beneficiaries of the ISSSTE Regional Hospital of Mérida, Yucatán, was analysed for 22 years. Disease activity and accumulated damage were evaluated using the MEX-SLEDAI scale and the SLICC-ACR-DI, respectively, and its correlation with clinical and demographic variables. RESULTS: 185 female and 15 male patients were analysed. Average accumulated damage and activity indices during follow-up were 4.63 and 1.10, respectively. The activity index was significantly lower in females compared to males (4.36 vs 7.43), and the accumulated damage did not present a difference by sex. The manifestations associated with greater activity were the mucocutaneous and articular ones, and the organs with the greatest accumulated damage were the musculoskeletal, neurological and gonadal. A relationship between the indices was found with the evolution time, remissions/reactivations, and persistent activity. Mortality was related to persistent activity due to systemic vascular complications and kidney and liver failure. The annual incidence and prevalence of SLE calculated was 2.86% and 48.43% in Yucatán Peninsula. CONCLUSIONS: The patients presented persistent activity, with mild to moderate reactivations, and accumulated damage more aggressive in men. The clinical activity decreases and increases the accumulated damage at a longer evolution time, with less kidney disease and greater survival, which suggests a more benign course in the population of the Yucatan Peninsula.

RESUMO

Introducción: Los anticuerpos contra el citoplasma del neutrófilo se detectan normalmente en pacientes con vasculitis. Aunque estos anticuerpos pueden estar presentes en un amplio número de enfermedades asociadas a estados inflamatorios y autoinmunes, como la artritis reumatoide, no se ha demostrado su significado clínico. Objetivo: evaluar la utilidad de diferentes especificidades antigénicas de los anticuerpos contra el citoplasma del neutrófilo para medir la actividad clínica en pacientes cubanos con artritis reumatoide. Material y Métodos: Se realizó un estudio transversal con 77 pacientes cubanos con artritis reumatoide. Se determinaron la velocidad de sedimentación globular, la proteína C reactiva, el indicador clínico de actividad de la enfermedad, los anticuerpos anti-proteínas citrulinadas, el factor reumatoide y los anticuerpos contra el citoplasma del neutrófilo frente a diferentes especificidades antigénicas. Resultados: La mayor cantidad de pacientes con actividad clínica elevada (> 5,1) pertenecieron al grupo de pacientes positivos de anticuerpos contra el citoplasma del neutrófilo (p=0,0364). Los pacientes con anticuerpos anti-lactoferrina tuvieron mayores valores de actividad clínica (p=0,0304). Mediante análisis multivariado se demostró la influencia de la positividad de anticuerpos anti-lisozima (p=0,0391), de la positividad doble de los anticuerpos anti-proteínas citrulinadas y anti-lactoferrina (p=0,0282), así como de la doble positividad de los anticuerpos anti-proteínas citrulinadas y anti-elastina (p=0,0182) en la actividad clínica. Conclusión: La presencia de anticuerpos contra el citoplasma del neutrófilo que reconocen las especificidades antigénicas lisozima, lactoferrina y elastina se relacionan con mayor actividad clínica en pacientes con artritis reumatoide(AU)

Introduction: Antibodies against neutrophil cytoplasm are normally detected in patients with vasculitis. Although these antibodies can be present in a wide number of diseases associated with inflammatory and autoimmune conditions such as rheumatoid arthritis, their clinical significance has not been demonstrated. Objective: To evaluate the usefulness of different antigenic specificities of antibodies against neutrophil cytoplasm to measure the clinical activity in Cuban patients with rheumatoid arthritis. Material and Methods: A cross-sectional study was conducted on 77 Cuban patients with rheumatoid arthritis. Erythrocyte sedimentation rate, C-reactive protein, the clinical indicator of disease activity, anti-citrullinated protein antibodies, rheumatoid factor, and antibodies against neutrophil cytoplasm against different specificities were determined. Results: The largest number of patients with elevated disease activity (> 5.1) belonged to the group of antibodies against neutrophil cytoplasm positive patients (p=0.0364). Patients with anti-lactoferrin antibodies had higher disease activity values ​​(p=0.0304). Through multivariate analysis, the influence of positive anti-lysozyme antibodies (p=0.0391), of double positivity of anti-citrullinated protein and anti-lactoferrin antibodies (p=0.0282), as well as that of double positivity of anti-citrullinated protein and anti-elastin antibodies (p=0.0182) on disease activity were demonstrated. Conclusion: The antibodies against neutrophil cytoplasm that recognize the antigenic specificities of lysozyme, lactoferrin and elastin are related to higher clinical activity in patients with rheumatoid arthritis(AU)

RESUMO

Introducción: la normativa actual de docencia clínica regula el desarrollo de actividades curriculares disminuyendo el tiempo de con-tacto estudiante-paciente, requiriendo entre otras destrezas del estudiante la lectura eficiente de información clínica. La simulación permite desarrollar competencias clínicas en los estudiantes de ciencias de la salud. El objetivo de este estudio es describir la experiencia de talleres de fichas clínicas simuladas (FCS) en estudiantes curriculares y reportar indicadores de logro de objetivos de aprendizaje relacionados al reconocimiento de las partes de la ficha clínica e identificación y extracción de información relevante. Metodología: en una asignatura de carácter mínimo previo al encuentro de estudiantes con pacientes reales, se desarrollaron cuatro talleres de FCS en grupo pequeño. Un académico guió la actividad consistente en responder cuestionarios de ubicación de información presente en las FCS. Al finalizar la asignatura, se evaluó la percepción de la didáctica educativa y logro de objetivos de aprendizaje en tutores clínicos y estudiantes mediante encuesta. Resultados: los estudiantes reportaron alta satisfacción con la metodología, facilidad para extraer información relevante y mayor tiempo de contacto clínico con pacientes reales. Los tutores clínicos informaron que los estudiantes logran reconocer las partes de la ficha clínica. Ambos consideran que el tiempo ideal para lectura de ficha clínica es de 10 a 20 minutos.Conclusión: la incorporación de talleres de fichas clínicas simuladas desarrolló habilidades clínicas de reconocimiento de las partes que componen la ficha clínica, optimizando el tiempo necesario para identificar y extraer información relevante a diferentes escenarios clínicos.

RESUMO

OBJECTIVE: To evaluate the association between the clinical activity of RA patients and serum adipocytokines (Leptin, Adiponectin and Resistin) and inflammatory cytokines. METHODS: All RA patients fulfilled ACR 1987 criteria and were treated with DMARDs. Adipocytokine and inflammatory cytokine levels were evaluated using ELISA. RESULTS: 121 patients were included in the study. Stratifying according to DAS28 (low, moderate and high activity), there were significant differences for Leptin, Resistin, IL-6 and IL-17, however, no differences were seen for Adiponectin, TNFα or IL-1ß. Clinical activity positively correlated with Leptin, Resistin, IL-17 and IL-6 levels, but not with Adiponectin, TNFα or IL-1ß. Adiponectin levels negatively correlated with TNFα and positively correlated with IL-1ß. IL-1ß positively correlated with IL-6 and negatively correlated with TNFα and IL-17. CONCLUSION: Circulating Leptin, Resistin, IL-6 and IL-17 levels positively correlate with RA clinical activity in a manner independent of the subject's BMI. Complex relationships between inflammatory cytokines were observed in RA patients suggesting that other metabolic or inflammatory factors could be involved.
