ABSTRACT
Background and objective The aim of this research was to investigate the relationship between disease activity and health-related quality of life (HRQoL) in patients with systemic lupus erythematosus (SLE) considering the increased interest in the management of this disease. Materials and methods HRQoL was measured at clinic visits during a 12-month follow-up period using questionnaires on fatigue (FACIT-FATIGUE); quality of life, EuroQol 5-dimension (EQ-5D-5L) health questionnaire with 5 levels; disability, Health Assessment Questionnaire (HAQ), and a Global Health Status (GHS) scale. Disease activity, organ damage and other clinical factors that could affect HRQoL were recorded. The association between disease activity and HRQoL was assessed using Bayesian linear regression models with monotonic effects. Results Data from 70 patients at the baseline visit and 42 patients with 1 year of follow-up were analyzed. At baseline, 28.57% of patients presented Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)>6. In the 70 baseline patients, disease activity was associated with HRQoL in all four parameters. In the 42 patients with 12 months of follow-up, the positive association of disease activity with GHS, FACIT-FATIGUE and EQ-5D-5L and the negative association with HAQ was maintained.Patients who are smokers and those receiving immunosuppressant therapy presented low GHS and FACIT-FATIGUE scores. Moreover, older age at inclusion was significantly associated to low GHS, while low leucocyte and 25-OH-vitamin D levels were associated to fatigue perception in SLE patients. Conclusion Our results showed a statistically significant association between disease activity and HRQoL parameters. (AU)
Objetivo El objetivo del estudio fue analizar la relación entre la actividad clínica y la calidad de vida relacionada con la salud (CVRS) en pacientes con lupus eritematoso sistémico (LES).Material y métodos La CVRS se evaluó en la visita basal y durante 12 meses de seguimiento mediante un cuestionario de fatiga (FACIT-FATIGUE), calidad de vida (EQ-5D-5L), discapacidad (HAQ) y una escala analógica visual de estado general de salud (EVA). La actividad clínica, el daño acumulado y otros factores clínicos que pudieran afectar a la CVRS se analizaron mediante un modelo de regresión lineal bayesiano con efectos monotónicos. Resultados Se analizaron los datos de 70 pacientes incluidos en la visita basal y los 42 con 12 meses de seguimiento seleccionados aleatoriamente. En la visita basal el 28,57% de los pacientes presentaban un índice SLEDAI>6. La actividad clínica medida mediante el índice SLEDAI se asociaba de forma estadísticamente significativa a los 4 parámetros de CVRS. En los 42 pacientes con un año de seguimiento la relación directa entre la actividad clínica y el FACIT-FATIGUE, EVA y EQ-5D-5L, así como la relación indirecta con el HAQ, se mantuvieron. Los pacientes fumadores y aquellos bajo tratamiento inmunosupresor presentaban valores disminuidos de EVA y FACIT-FATIGUE. Además, los pacientes con edades más avanzadas presentaban valores disminuidos de EVA, y aquellos con niveles bajos de vitamina D o leucopenia presentaban mayor percepción de fatiga. Conclusión La actividad clínica se asocia a diferentes dominios de la CVRS, apoyando la evaluación de la CVRS como complemento en el manejo del LES. (AU)

Objectives: DNA hydroxymethylation may be induced by oxidative stress in lupus patients, so we investigated the association between DNA hydroxymethylation and demethylation with the antioxidant response.MethodsA casecontrol study was performed including lupus patients and matched healthy controls. Serum concentration of glutathione (GSH), glutathione disulphide (GSSG), superoxide dismutase (SOD) and total antioxidant capacity (TAC), 5-mC and 5-hmC were determined.ResultsOne hundred and forty-two patients and 34 controls were included. 5-hmC levels were lower in SLE patients than in controls. GSH and GSSG values were lower in patients, while SOD levels were higher in patients. TAC did not show significant differences, but higher demethylation and lower hydroxydemethylation were associated to increased TAC values. Lower demethylation was associated with cytopenia and lower hydroxymethylation with longer course of the disease. Lower levels of GSH and GSSG and higher SOD values were associated with accumulated damage assessed by SLICC-ACR.ConclusionsLower hydroxymethylation in patients than in controls was observed. Moreover, higher demethylation and lower hydroxymethylation leads to high TAC levels. DNA hydroxymethylation seems to be related to longer course of the disease. (AU)
Objetivos: La hidroximetilación del ADN puede estar inducida por el estrés oxidativo en pacientes de lupus, por lo que estudiamos la asociación entre hidroximetilación del ADN y desmetilación sin respuesta antioxidante.MétodosSe realizó un control de casos que incluyó a pacientes de lupus pareados con controles sanos. Se calcularon la concentración sérica de glutatión (GSH), glutatión disulfuro (GSSG), superóxido dismutasa (SOD), capacidad antioxidante total (CAT), 5-mC y 5-hmC.ResultadosSe incluyeron 142 pacientes y 34 controles. Los niveles de 5-hmC fueron menores en el grupo de pacientes de LES que en el de controles. Los valores de GSH y GSSG fueron menores en el grupo de pacientes, mientras que los valores de SOD fueron superiores en el grupo de pacientes. La CAT no reflejó diferencias significativas, pero el incremento de desmetilación y la disminución de hidroximetilación estuvieron asociados al incremento de los valores de la CAT. La disminución de la desmetilación estuvo asociada a citopenia, y la disminución de la hidroximetilación a un curso más corto de la enfermedad. Los niveles menores de GSH y GSSG, y los valores superiores de SOD estuvieron asociados a una acumulación del daño, según lo evaluado mediante SLICC-ACR.ConclusionesSe observó menor hidroximetilación en los pacientes que en los controles. Además, el incremento de la desmetilación y la disminución de la hidroximetilación conllevan unos altos niveles de CAT. La hidroximetilación del ADN parece estar relacionada con un curso más largo de la enfermedad. (AU)

Amebic liver abscess is an emergent disease in Spain due to immigration and travel to endemic countries. Although mainly pharmacological, treatment can sometimes require drainage, especially when there is a high risk of rupture due to location or size. We report a case of amebic liver abscess that, due to its large size and lack of response to metronidazole therapy, required percutaneous drainage. This technique, with ultrasound-guided percutaneous aspiration, would be indicated in lesions with a diameter of > 5 cm, abscesses of the left lobe, and those unresponsive to medical treatment.

El absceso hepático amebiano puede ser una enfermedad emergente en España a causa de la inmigración y los viajes a países endémicos. Su tratamiento, aunque básicamente es de tipo farmacológico, en ocasiones puede requerir un drenaje, sobre todo cuando por la localización o el tamaño hay un alto riesgo de rotura. Presentamos un caso que, por falta de respuesta al tratamiento con metronidazol y su excesivo tamaño, precisó un drenaje percutáneo. Este procedimiento, habitualmente realizado mediante punción-aspiración controlada ecográficamente, estaría indicado en lesiones mayores de 5 cm, en abscesos situados en el lóbulo izquierdo o en casos sin respuesta al tratamiento médico
