RESUMO

The use of hydroxychloroquine (HCQ) in Primary Sjögren's Syndrome (pSS) has been assessed in different studies over the last years, with conflicting results regarding its efficacy in sicca syndrome and extraglandular manifestations (EGM). The goal of this study was to compare the incidence rate of EGM in pSS patients with and without HCQ therapy.We performed a multicenter retrospective study, including patients with pSS (European classification criteria) with at least 1 year of follow-up. Subjects with concomitant fibromyalgia, autoimmune hepatitis, primary biliary cirrhosis, and primary sclerosing cholangitis were excluded. Demographics and pSS characteristics were recorded. The EGM were defined by EULAR-SS disease activity index (ESSDAI). Patients were divided into two groups according to their use or not of HCQ therapy. We evaluated the use of HCQ and its relationship to EGM. HCQ therapy was defined as the continuous use of the drug for at least 3 months. A descriptive analysis of demographics and pSS characteristics was performed. We compared the incidence of EGM between groups defined by HCQ therapy using chi2 test or Fisher's exact test. A total of 221 patients were included (97.3% women), mean age, 55.7 years (SD 14). Mean age at diagnosis, 48.8 years (SD 15); median disease duration, 60 months (IQR 35-84). One hundred and seventy patients (77%) received HCQ. About half of the patients had at least one EGM during the course of the disease, 20% of them developed an EGM before the onset of the sicca syndrome and 26% simultaneously with dryness symptom. Overall, EGM were less frequent in those on HCQ therapy (36.5% vs 63.5%, p < 0.001). Considering each EGM individually, the following manifestations were more frequent in the non-treated group: arthritis (p < 0.001), fatigue (p < 0.001), purpura (p = 0.01), Raynaud phenomenon (p = 0.003), and hypergammaglobulinemia (p = 0.006). Immunosuppressive treatment was indicated on 28 patients (12.7%), 13 of which were receiving also HCQ. The first reason for those treatments was the presence of arthritis in 12/28 patients (42.8%), and the drug used in all the cases was methotrexate. Only three patients required immunosuppressive therapy with cyclophosphamide, due to the presence of glomerulonephritis, vasculitis, and interstitial lung disease. None of the patients received biologic therapy. The lower incidence of EGM was observed in patients on HCQ therapy supports its efficacy in pSS. However, further large scale prospective studies are needed to confirm these findings.

RESUMO

Introducción: La utilización de agentes biológicos para el tratamiento de la Artritis Reumatoidea (AR) es habitualmente usada en aquellos pacientes con enfermedad activa que no hayan respondido al tratamiento con drogas modificadoras de la Artritis Reumatoidea convencionales (DMARD, por sus siglas en inglés) o que hayan presentado intolerancia a las mismas. Al estado actual de la evidencia, la terapia combinada de agentes biológicos más un DMARD convencional (principalmente metotrexato) constituye el estándar de tratamiento. Sin embargo existen algunos escenarios como la intolerancia, la falta de adherencia y la aparición de eventos adversos a las DMARDs convencionales donde la monoterapia biológica emerge como una opción terapéutica válida. Según los distintos registros a nivel internacional, la frecuencia de utilización de agentes biológicos en monoterapia oscila entre 12 a 39%. Debido a la ausencia de estos datos a nivel local decidimos realizar este estudio para conocer el porcentaje de pacientes que se encuentran en monoterapia biológica y analizar las causas que llevaron a este tipo de tratamiento. Materiales y métodos: Estudio de tipo corte transversal donde se invitó a participar a diferentes centros reumatológicos distribuidos a lo largo de Argentina. Cada centro revisó las historias clínicas de los últimos 30 a 50 pacientes consecutivos vistos con AR, mayores de 18 años, que habían presentado inadecuada respuesta al tratamiento con DMARDs y que estaban bajo tratamiento biológico. Se completaba una ficha por cada paciente incluido, registrando datos demográficos, de la enfermedad y tratamientos previos. Resultados: Se incluyeron 32 centros y se evaluaron 1148 historias clínicas de pacientes con AR durante el mes de octubre y noviembre del 2012. Un 21,4% (246) de los pacientes al momento del estudio se encontraba bajo tratamiento biológico en monoterapia...


Introduction: The use of biological agents for the treatment of rheumatoid arthritis (RA) is commonly used in patients with active disease who have not responded to treatment with conventional rheumatoid arthritis-modifying drugs (DMARDs) or Who have presented intolerance to them. At the present state of evidence, combined therapy of biological agents plus conventional DMARD (mainly methotrexate) is the standard of treatment. However, there are some scenarios such as intolerance, lack of adherence and the appearance of adverse events to conventional DMARDs where biological monotherapy emerges as a valid therapeutic option. According to different international registries, the frequency of use of biological agents in monotherapy ranges from 12 to 39%. Due to the absence of these data at the local level we decided to carry out this study to know the percentage of patients who are in biological monotherapy and to analyze the causes that led to this type of treatment. Materials and methods: A cross-sectional study where different rheumatologic centers throughout Argentina were invited to participate. Each center reviewed the medical records of the last 30 to 50 consecutive patients seen with RA, older than 18 years, who had inadequate response to treatment with DMARDs and who were under biological treatment. One card was completed for each patient included, recording demographic, disease and previous treatment data. Results: Thirty-two centers were included and 1148 clinical records of patients with RA were evaluated during October and November 2012. A total of 244 patients (246) at the time of the study were under monotherapy...

RESUMO

El síndrome de Sjõgren es una enfermedad reumática autoinmune, sistémica, que supone la destrucción de la glándula exocrina y órganos internos por medio de grandes infiltraciones mononucleares asociadas con los anticuerpos Ro/SSA, La/SSB y factores reumáticos, ambos síntomas principales de los factores celulares y humorales de la xeroftalmia y la xerostomía. Los infiltrados mononucleares más comunes son los linfocitos CD4, CD8 y B. Los pacientes que sufren de síndrome de Sjõgren corren el riesgo de desarrollar linfoma no Hodgkin. El linfoma folicular es el resultado de una traslocación no homóloga cromosómica 14; 18 produciendo la desregulación de la transcripción y síntesis de la proteína Bcl2. Las proteínas de la familia Bcl2 son reguladores clave de la apoptosis, que estimulan la supervivencia de la célula. Otros grupos de la familia Bcl2 son estimuladores pro-apoptóticos. El comportamiento de las células dependerá de la concentración de los dos miembros de la familia. Objetivos: Los niveles de expresión y apoptosis de Bcl2 en la glándula salival menor pre y pos-tratamiento con agonistas colinérgicos. Pacientes y métodos: Diagnóstico del síndrome de Sjõgren según los criterios europeos. Se eclutaron 10 pacientes, a quienes se estudió durante 5 meses y se los trató con 15 mg de clorhidrato de pilocarpina en cápsulas orales de 5 mg cada 8 horas. Se llevaron a cabo biopsias pre-tratamiento y pos-tratamiento desde el día cero (antes del tratamiento) hasta el quinto mes (después del tratamiento). Antes de ingresar al estudio clínico, los pacientes SSp voluntarios firmaron el consentimiento informado y el estudio se realizó según las normas de buenas prácticas clínicas. Se evaluó la expresión Bcl2 mediante técnicas de inmunohistoquímica y la apoptosis nucleotidil transferasa-peroxidasa mediante técnicas in situ. Diseño del estudio: Abierto, longitudinal, autocontrolado.
