RESUMO
OBJECTIVE: We aimed to identify the predictive factors of hospital-acquired bacterial infections in patients with systemic lupus erythematosus (SLE). METHODS: This chart review study included patients with SLE who were hospitalized between 2009 and 2020 for reasons other than infection. The outcome was defined as any infection confirmed using any bacterial isolation method or diagnosed by treating physicians and required treatment with intravenous antibiotics. For statistical analysis, logistic regression analyses were performed. RESULTS: In total, 1678 patients (87.6% women) were included. The median age was 33 years (interquartile range, 24-47 years). The incidence of hospital-acquired infections was 13.9% (233 infections). Age, Systemic Lupus Erythematosus Disease Activity Index score, Systemic Lupus International Collaborating Clinics damage score, blood urea nitrogen and C-reactive protein levels, dosage of steroid in the previous month, recent use of 1 or more immunosuppressants, admission with a central venous catheter (or dialysis catheter), and use of central venous catheter or bladder catheter in the first 5 days were the predictive factors of nosocomial infections. CONCLUSION: The patients' infection risk profile should be assessed to accurately determine the risk-benefit balance of any therapeutic intervention, minimize exposure to steroids and immunosuppressants, and maintain a low threshold for the early diagnosis of infections. Further studies should assess whether the modification of some identified factors could reduce the incidence of nosocomial infections.

ABSTRACT Introduction: Spondyloarthritis is a group of chronic inflammatory diseases. Several factors of the disease remain unknown, including clinical and radiological behavior, the demographic characteristics and burden of disease in Colombian patients. Objective: To characterize the demographic aspects, the clinical and paraclinical behaviour, and the therapeutic requirements of a cohort of patients with spondyloarthritis followed-up in the Hospital Pablo Tobón Uribe from January 1, 2005 to December 31, 2017. Methodology: Cohort study. The population was characteriszed using descriptive statistics, qualitative variables using simple and relative frequencies, and quantitative variables using means and standard deviation or medians with their interquartile ranges. Results: The cohort consisted of 181 patients, 100 men (54.9%) and 81 women (44.5%). Just under one half (45.1%) had ankylosing spondylitis, 18.1% undifferentiated spondyloarthritis, 17.1% psoriatic arthropathy, 14.8% reactive arthritis, and 4.4% inflammatory bowel disease. More than two-thirds (69.8%) of the patients had peripheral manifestations, and 67% had axial. A positive HLAB27 was observed in 55.6% of patients. The MRI showed acute and chronic changes in the sacroiliac in 69% and 37%, respectively, with radiological sacroiliitis being observed in 59.5% of cases. The large majority (91.1%) of the patients were treated with PII of original article: S0121-8123(21)00018-9 NSAIDs, 60.1% with sulfasalazine, 43.4% with COX2 inhibitors, and 33.7% with methotrexate. TNFa inhibitors were required by 56.6% of the subjects 3 years after the onset of symptoms. The most commonly used biological drugs were Adalimumab (31.1%), etanercept (21.7%), infliximab (13.1%), golimumab 6.1%, and certolizumab 0.5%. Conclusions: Ourpopulation was characterized by a high activity and functional compromise demonstrated by the high scores of BASDAI and BASFI, and because 56.6% of the patients required anti-TNFa agents.
RESUMEN Introducción: Las espondiloartritis son un grupo de enfermedades inflamatorias crónicas. Se desconoce su comportamiento en nuestro medio, al igual que el comportamiento clínico y radiológico, las características demográficas y la carga de enfermedad en los pacientes colombianos. Objetivos: Caracterizar los aspectos demográficos, el comportamiento clínico y paraclínico y los requerimientos terapéuticos de la cohorte de pacientes con espondiloartritis seguidos en el Hospital Pablo Tobón Uribe desde el 1.° de enero del 2005 hasta el día 31 de diciembre del 2017. Metodología: Estudio de cohorte. La población se caracterizó mediante estadística descrip tiva, las variables cualitativas mediante frecuencias simples y relativas, en tanto que para las cuantitativas se emplearon medias y desviación estándar o medianas con sus rangos intercuartílicos. Resultados: La cohorte está constituida por 181 pacientes, 100 hombres (54,9%) y 81 mujeres (44,5%). El 45,1% tenía espondilitis anquilosante, el 18,1% espondiloartritis indiferenciada, el 17,1% artropatía psoriásica, el 14,8% artritis reactiva y el 4,4% enfermedad inflamatoria intestinal. El 69,8% de los pacientes tenía manifestaciones periféricas y el 67% axiales. El 55,6% de los pacientes tuvo HLAB27 positivo. La RMN mostró cambios agudos y crónicos en las sacroilíacas en el 69% y 37%, respectivamente; en el 59,5% de los casos se observó sacroileítis radiológica. el 91,1% de los pacientes se trató con AINE, el 60,1% con sulfasa lazina, el 43,4% con inhibidores COX2 y el 33,7% con metotrexato. El 56,6% de los sujetos requirió inhibidores-TNFa 3 arios después del inicio de los síntomas. Los biológicos más uti lizados fueron adalimumab (31,1%), etanercept (21,7%), infliximab (13,1%), golumimab (6,1%) y certolizumab (0,5%). Conclusiones: Nuestra población se caracterizó por una alta actividad y gran compromiso funcional, lo que se refleja en altos puntajes de Basdai y Basfi y en que el 56,6% de los pacientes requirió agentes anti-TNFa.

RESUMEN Introducción: El uso de TNFi es cada vez más frecuente en los pacientes con espondiloartritis. Identificar tempranamente aquellos que los requerirán o poder predecir su uso puede ayudar a hacer un tratamiento más efectivo y oportuno racionalizando su uso. Objetivo: Determinar los factores qué mejor explican la indicación de TNFi en la población en estudio. Material y métodos: La asociación entre el uso de medicamentos anti-TNFα y las variables categóricas demográficas, clínicas, de laboratorio, radiológicas y de tratamiento se exploró por prueba exacta de Fisher. La asociación con las variables cuantitativas fue evaluada con t de Student o U de Mann Withney, de acuerdo con su distribución. Aquellas variables con p < 0,25 fueron ingresadas a modelos univariante de regresión logística explicativa para construir los OR crudos; aquellas con p < 0,25 se incluyeron en el modelo multivariante para construir OR ajustados. Resultados y discusión: La población está constituida por 181 pacientes. Modelo univariante: la artritis reactiva, uretritis y compromiso periférico fueron factores protectores para el uso de TNFi. Espondiloartritis axial, lumbalgia inflamatoria, dolor glúteo alternante, rigidez matinal sacroilitis demostrada por cualquier método, tratamiento con inhibidores COX-2, tiempo de evolución de tres arios o más y los puntajes de BASDAI y BASFI se asociaron con el uso de TNFi. Modelo multivariante: artritis reactiva (OR 0,1, IC 95% 0,012-0,86, p = 0,036), lumbalgia inflamatoria (OR 13,63, IC 95% 1,36-136, p = 0,026), sacroilitis (OR 7,71, IC 95% 1,04-57, p = 0,045, uso de coxib (OR 10,1, IC 95% 2,71-37,62, p = 0,001) y el puntaje máximo de BASDAI (4-6: OR 6,1, IC 95% 1,3-28,7, p = 0,022, mayor de 6: OR 15,8, IC 95% 2,2-113, p = 0,006) se asociaron independientemente con el uso de TNFi. El uso de coxib se asoció con la indicación de usar TNFi tanto en los pacientes con espondiloartritis axial (OR 4,2, IC 95% 1,74-10,11, p = 0,001) como periférica (OR 4, IC 95% 1,85-8,62, p < 0,001). Conclusiones: El inicio de la enfermedad en la forma de artritis reactiva se comportó como un factor protector para la necesidad posterior de usar TNFi, mientras que presentar lumbalgia inflamatoria, sacroilitis demostrada por cualquier método, el tratamiento con coxib y el puntaje máximo de BASDAI mayor de 4 se asociaron con el uso de estos medicamentos.
ABSTRACT Introduction: The use of tumor necrosis factor (TNF) alpha inhibitors is increasing in patients with spondyloarthritis. Early identification of those that would require them, or the ability to predict their use, could lead to a more effective and timely treatment by rationalizing their use. Objective: To determine factors that better explain the indication of TNFi in the study population. Material and methods: The association between anti-TNFα use and categorical demographic, clinical, laboratory, radiological and treatment variables was explored using Pearson's Chi2 or Fisher's exact test. The association with the quantitative variables was evaluated using Student's t test or Mann Whitney U test, depending on their distribution. Those variables with P < 0.25 were entered into univariate models of explanatory logistic regression to cons truct crude ORs, and those with P < 0.25 were included in the multivariate model to construct adjusted ORs. Results and discussion: The study population includes 181 patients. In the univariate model: reactive arthritis, urethritis, and peripheral involvement were protective factors for the use of TNFi. Axial spondyloarthritis, inflammatory lumbalgia, alternating gluteal pain, morning stiffness, sacroiliitis demonstrated by any method, treatment with COX-2 inhibitors, evolu tion time of three years or more, and BASDAI and BASFI scores were associated with the use of TNFi. Multivariate model: reactive arthritis (P = 0.036), inflammatory back pain (P = 0.026), sacroiliitis (P = 0.045), use of coxibs (P = 0.001) and the maximum score of BASDAI (P = 0.022, P = 0.006) were independently associated with the use of TNFi. The use of coxibs was associa ted with the indication of using TNFi in both patients with axial spondyloarthritis (P = 0.001) and peripheral (P < 0.001). Conclusions: The onset of the disease in the form of reactive arthritis behaved as a protective factor for the subsequent need to use TNFi, while presenting with inflammatory back pain, sacroiliitis, demonstrated by any method, treatment with coxibs, and the maximum score of BASDAI greater than 4 associated with the use of these medications.

RESUMEN Introducción: Los pacientes con lupus eritematoso sistémico (LES) tienen un riesgo aumen tado de padecer infecciones tanto adquiridas en la comunidad como asociadas con el cuidado de la salud. Las infecciones bacterianas son las más frecuentes y graves durante la hospitalización de estos pacientes. Objetivo: Desarrollar y validar internamente un modelo de predicción clínica de pronóstico del riesgo de infección bacteriana adquirida en el hospital en pacientes con LES, usando datos clínicos y de laboratorio obtenidos durante las primeras horas de hospitalización. Métodos: Se analizó una cohorte retrospectiva de pacientes con LES mayores de 16 arios, hos pitalizados por motivos diferentes a infección bacteriana en 2 hospitales de alta complejidad de Medellín entre 2011 y 2016. Se compararon las características de los pacientes que des arrollaron el desenlace de infección bacteriana entre el día 3 y el día 15 de hospitalización con aquellos que no lo presentaron. Las variables significativas en el análisis bivariado fueron consideradas para la construcción del modelo por medio de regresión logística multivariada. Resultados: Se incluyeron 765 episodios, de los cuales 98 (12,8%) presentaron el desenlace de interés. Se consideraron 35 predictores candidatos. Las variables incorporadas en el modelo final fueron: edad, recuento de neutrófilos, puntaje de actividad lúpica SLEDAI, uso de sonda vesical, uso de catéter venoso central en las primeras 72 h, dosis de glucocorticoides en el mes previo y el uso de un antimalárico en los 3 meses previos. La capacidad de discrimi nación del modelo fue aceptable a buena (AUC-ROC 0,74; IC 95% 0,69-0,80). La prueba de bondad de ajuste de Hosmer-Lemeshow (p = 0,637) evidenció una adecuada calibración. Conclusión: Desarrollamos un modelo de predicción clínica de pronóstico del riesgo de infec ción bacteriana nosocomial en pacientes con LES. El modelo desarrollado está compuesto por variables clínicas y de laboratorio simples disponibles en el momento del ingreso al hospital. Se requieren estudios de validación externa y de impacto clínico antes de su implementación rutinaria.
ABSTRACT Introduction: Patients with systemic lupus erythematosus (SLE) have an increased risk of developing community-acquired infections, as well as those associated with health care. Bacterial infections are the most common and serious while these patients are in hospital. Objective: To develop, and internally validate, a clinical prediction model for the prognosis of the risk of hospital-acquired bacterial infection in SLE patients using clinical and laboratory data obtained during the first hours of hospital admission. Methods: An analysis was performed on retrospective cohort of patients with SLE older than 16 years and admitted for reasons other than bacterial infection in 2 highly complex hospitals in Medellín between 2011 and 2016. The characteristics of the patients who developed a bacterial infection were compared between day 3 and day 15 of hospital admission with those who did not develop one. The significant variables in the bivariate analysis were used for the construction of the model using multivariate logistic regression. Results: A total of 765 episodes were included, of which 98 (12.8%) presented the outcome of interest. Thirty-five candidate predictors were considered. The variables incorporated in the final model were: age, neutrophil count, SLEDAI lupus activity score, use of a bladder catheter, use of a central venous catheter in the first 72 h, glucocorticoid doses in the previous month, and use of an antimalarial drug in the 3 previous months. The discrimination capacity of the model was acceptable to good (AUC-ROC 0.74; 95% CI 0.69-0.80). The Hosmer-Lemeshow goodness of fit test (P = .637) suggested adequate calibration. Conclusion: A clinical prediction model of prognostic risk of nosocomial bacterial infection in patients with SLE has been developed. This model is made up of simple clinical and laboratory variables available at the time of hospital admission. External validation and clinical impact studies are required before routine implementation.

INTRODUCTION: Having reliable predictive models of prognosis/the risk of infection in systemic lupus erythematosus (SLE) patients would allow this problem to be addressed on an individual basis to study and implement possible preventive or therapeutic interventions. OBJECTIVE: To identify and analyze all predictive models of prognosis/the risk of infection in patients with SLE that exist in medical literature. METHODS: A structured search in PubMed, Embase, and LILACS databases was carried out until May 9, 2020. In addition, a search for abstracts in the American Congress of Rheumatology (ACR) and European League Against Rheumatism (EULAR) annual meetings' archives published over the past eight years was also conducted. Studies on developing, validating or updating predictive prognostic models carried out in patients with SLE, in which the outcome to be predicted is some type of infection, that were generated in any clinical context and with any time horizon were included. There were no restrictions on language, date, or status of the publication. To carry out the systematic review, the CHARMS (Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies) guideline recommendations were followed. The PROBAST tool (A Tool to Assess the Risk of Bias and Applicability of Prediction Model Studies) was used to assess the risk of bias and the applicability of each model. RESULTS: We identified four models of infection prognosis in patients with SLE. Mostly, there were very few events per candidate predictor. In addition, to construct the models, an initial selection was made based on univariate analyses with no contraction of the estimated coefficients being carried out. This suggests that the proposed models have a high probability of overfitting and being optimistic. CONCLUSIONS: To date, very few prognostic models have been published on the infection of SLE patients. These models are very heterogeneous and are rated as having a high risk of bias and methodological weaknesses. Despite the widespread recognition of the frequency and severity of infections in SLE patients, there is no reliable predictive prognostic model that facilitates the study and implementation of personalized preventive or therapeutic measures.Protocol registration number: PROSPERO CRD42020171638.

OBJECTIVE: To identify factors associated with active tuberculosis (TB) in patients with systemic lupus erythematosus (SLE). METHODS: We performed a retrospective case-control study in two tertiary care teaching hospitals in Medellín, Colombia. From January 2007 to December 2017, a total of 268 patients with SLE were included. SLE patients with TB (cases) were matched 1:3 with SLE patients without TB (controls) by disease duration and the date of the hospitalization in which the diagnosis of TB was made (index date of cases) to the nearest available rheumatology hospitalization in the matched controls (± 2 years). Conditional univariable and multivariable logistic regression analyses were performed. RESULTS: Sixty-seven cases and 201 controls were assessed. Only pulmonary TB occurred in 46.3%, only extrapulmonary TB in 16.4% and disseminated TB in 37.3% of cases. Multivariable logistic regression analysis showed that lymphopenia (OR, 2.91; 95% CI 1.41-6.03; P = 0.004), 12-month cumulative glucocorticoid dose ≥ 1830 mg (OR, 2.74; 95% CI 1.26-5.98; P = 0.011), and having been treated with ≥ 2 immunosuppressants during the last 12 months (OR, 2.81; 95% CI 1.16-6.82; P = 0.022) were associated with TB after adjusting for age, sex, ethnicity, disease duration, disease activity, and comorbidity index. A trend towards an association of kidney transplantation with TB was also found (OR, 3.77; 95% CI 0.99-14.30; P = 0.051). CONCLUSION: Among SLE patients, cumulative glucocorticoid dose, lymphopenia, and the use of ≥ 2 immunosuppressants during the last 12 months were associated with active TB infection. Key Points ⢠Among SLE patients, a cumulative dose of glucocorticoids equivalent to 5 mg/day of prednisone during the last 12 months is independently associated with the development of TB. ⢠The use of two or more immunosuppressants during the last 12 months is also a risk factor for TB infection development is SLE patients. ⢠Lymphopenia is predominant in SLE patients with TB, being especially profound in those with disseminated TB. ⢠Renal transplant recipients with SLE also have an elevated risk of TB.

INTRODUCCIÓN: La sarcoidosis es una enfermedad compleja, de etiología desconocida, de curso variable y con formas de presentación diversas. Nuestro objetivo fue caracterizar a todos nuestros pacientes con sarcoidosis con énfasis en su forma de presentación clínica y establecer diferencias entre los pacientes con sarcoidosis con y sin compromiso articular. MÉTODOS: Se revisaron las historias clínicas de todos los pacientes con diagnóstico de sarcoidosis que fueron atendidos en el Hospital Pablo Tobón Uribe de Medellín, Colombia, desde enero de 2002 hasta abril de 2017. RESULTADOS: Se encontraron 22 pacientes con sarcoidosis. Hubo síntomas articulares en 13 de ellos. Todos los pacientes con sarcoidosis articular, excepto uno, tuvieron compromiso cutáneo concomitante (92%), lo cual fue mucho menos frecuente en los pacientes sin compromiso articular (22%) (OR=4,2; p < 0,001). CONCLUSIONES: Los pacientes con sarcoidosis que tienen compromiso articular presentan una frecuencia mucho mayor de compromiso cutáneo concomitante. La ausencia de hallazgos en piel en un paciente con síntomas articulares disminuye la probabilidad de que se trate de sarcoidosis
INTRODUCTION: Sarcoidosis is a complex disease of unknown etiology, with a variable course and highly different forms of presentation. Our objective was to characterize all our patients with sarcoidosis with emphasis on their clinical presentation and to establish differences between patients with sarcoidosis with and without joint involvement. METHODS: We reviewed the medical records of all patients with a diagnosis of sarcoidosis who were treated at the outpatient or inpatient services of the Pablo Tobón Uribe Hospital in Medellín, Colombia, from January 2002 to April 2017. RESULTS: We identified 22 patients with sarcoidosis. There were joint symptoms in 13 of them. All but one of the patients with sarcoidosis affecting the joints had concomitant skin involvement (92%), which was much less frequent in patients without joint involvement (22%) (odds ratio=4.2; P<.001). CONCLUSIONS: Patients with sarcoidosis who have joint involvement have a much higher frequency of concomitant skin involvement. The absence of cutaneous findings in a patient with joint symptoms decreases the likelihood of sarcoidosis

Objective: To develop a multivariable clinical prediction model for the requirement of aggressive immunosuppression with cytostatics, based on simple clinical record data and lab tests. The model is defined in accordance with the result of the kidney biopsies. Methods: Retrospective study conducted with data from patients 16 years and older, with SLE and nephritis with less than 6 months of evolution. An initial bivariate analysis was conducted to select the variables to be included in a multiple logistic regression model. Goodness of fit was evaluated using a Hosmer-Lemeshow test (H-L) and the discrimination capacity of the model by means of the area under the ROC (AUC) curve. Results: Data from 242 patients was gathered; of these, 18.2% (n=44) did not need an addition of cytostatics according to the findings of their kidney biopsies. The variables included in the final model were 24-h proteinuria, diastolic blood pressure, creatinine, C3 complement and the interaction of hematuria with leukocyturia in urinary sediment. The model showed excellent discrimination (AUC=0.929; 95% CI=0.894-0.963) and adequate calibration (H-L, P=.959). Conclusion: In recent-onset LN patients, the decision to use or not to use intensive immunosuppressive therapy could be performed based on our prediction model as an alternative to kidney biopsies
Objetivo: Desarrollar un modelo multivariado de predicción clínica basado en datos sencillos de la historia clínica y de las pruebas de laboratorio de la necesidad de inmunosupresión intensiva con citostáticos, definida de acuerdo con el resultado de la biopsia renal, en pacientes con LES y nefritis de reciente inicio. Metodología: Se realizó un estudio retrospectivo en 2 hospitales de tercer nivel en el que se recolectó información de pacientes mayores de 16 años con LES y nefritis de menos de 6 meses de evolución. Se realizó un análisis bivariado inicial para seleccionar las variables a incluir en un modelo de regresión logística múltiple. Se evaluó la bondad de ajuste por medio del estadístico de Hosmer-Lemeshow (H-L) y la capacidad de discriminación del modelo mediante área bajo la curva ROC (AUC). Resultados: Se recolectó información de 242 pacientes, de los cuales el 18,2% (n=44) no necesitaba tratamiento intensivo con citostáticos de acuerdo con los hallazgos de la biopsia renal. Las variables incluidas en el modelo final fueron proteinuria en 24h, presión arterial diástolica, creatinina, complemento C3 y la combinación de hematuria con leucocituria presentes en el análisis del sedimento urinario. El modelo mostró una excelente capacidad de discriminación (AUC=0,929; IC del 95%=0,894-0,963) y adecuada calibración (H-L=0,959). Conclusión: En pacientes con NL de reciente inicio, la decisión de usar o no terapia inmunosupresora intensiva podría ser realizada sobre la base de nuestro modelo de predicción como una alternativa a la biopsia renal

OBJECTIVES: The aims of this study were to describe clinical and laboratory manifestations of patients with levamisole-adulterated cocaine-induced vasculitis/vasculopathy and to propose a skin classification according to the distribution and severity of lesions. METHODS: We report the characteristics of 30 patients admitted with levamisole-adulterated cocaine-induced vasculitis/vasculopathy in 4 high-complexity institutions in Colombia, from December 2010 to May 2017. We compare our findings with the main published series. RESULTS: Median age was 31 years (interquartile range, 27-38 years) with a male-to-female ratio of 5:1. Eighty-three percent of the patients had retiform purpura affecting the limbs, buttocks, face, or abdomen; 73% had ear necrosis, 50% cutaneous ulcers, 17% genital necrosis, 13% oral ulcers, and 10% digital necrosis. Cutaneous involvement was classified according to the frequency of the compromised corporal area, and purpuric lesions were stratified in 4 grades of severity. Anti-neutrophil cytoplasmic autoantibodies were positive in 85% of the cases, lupus anticoagulant in 73%, and antinuclear autoantibodies in 57%; rheumatoid factor was negative in all cases. We found nephritis in 17 cases (57%). Prednisolone was used in most of the patients (70%), with other immunosuppressive agents being used in a lower percentage. Improvement was observed in 93% of the patients, but symptoms recurred in 40%, attributed to relapses in consumption. End-stage chronic renal disease developed in 10% of the cases, and 1 patient died. CONCLUSIONS: Because of rising cocaine consumption and levamisole adulteration frequency, levamisole-adulterated cocaine-induced vasculitis/vasculopathy is becoming more common. Detailed characterization of skin involvement coupled with multiple antibody positivity is essential for a diagnosis. Renal involvement is frequent, clinically and histologically heterogeneous, and potentially serious.

OBJECTIVE: To develop a multivariable clinical prediction model for the requirement of aggressive immunosuppression with cytostatics, based on simple clinical record data and lab tests. The model is defined in accordance with the result of the kidney biopsies. METHODS: Retrospective study conducted with data from patients 16 years and older, with SLE and nephritis with less than 6 months of evolution. An initial bivariate analysis was conducted to select the variables to be included in a multiple logistic regression model. Goodness of fit was evaluated using a Hosmer-Lemeshow test (H-L) and the discrimination capacity of the model by means of the area under the ROC (AUC) curve. RESULTS: Data from 242 patients was gathered; of these, 18.2% (n=44) did not need an addition of cytostatics according to the findings of their kidney biopsies. The variables included in the final model were 24-h proteinuria, diastolic blood pressure, creatinine, C3 complement and the interaction of hematuria with leukocyturia in urinary sediment. The model showed excellent discrimination (AUC=0.929; 95% CI=0.894-0.963) and adequate calibration (H-L, P=.959). CONCLUSION: In recent-onset LN patients, the decision to use or not to use intensive immunosuppressive therapy could be performed based on our prediction model as an alternative to kidney biopsies.

Neuropsychiatric Systemic Lupus Erythematosus (NPSLE) has multiple pathogenic mechanisms that cause diverse manifestations and whose diagnosis is challenging because of the absence of appropriate diagnostic tests. In the present study the application of proteomics using two-dimensional electrophoresis (2D) and mass spectrometry (MS) allowed the comparison of the protein profile of the serum low and high abundance protein fractions of NPSLE patients (NPSLE group) and SLE without neuropsychiatric syndromes (SLE group), Neuropsychiatric syndromes not associated with SLE (NPnoSLE groups), and healthy controls (CTRL group). The gels obtained were digitalized and analyzed with the PDQuest software. The statistical analysis of the spots was performed using the nonparametric Kruskal Wallis and Dunn's multiple comparison tests. Two spots showed significant differences and were identified by MS. Spot 4009 was significantly lower in NPSLE with regard to NPnoSLE (p= 0,004) and was identified as apolipoprotein A1 (APOA1) (score 809-1132). Spot 8001 was significantly higher in NPSLE regarding CTRL and NPnoSLE (p= 0,01 y 0,03, respectively) and was identified as serum amyloid A (SAA) (score 725-2488). The proinflammatory high density lipoproteins (HDL) have been described in SLE. In this HDL the decrease of APOA1 is followed by an increase in SAA. This altered level of both proteins may be related to the inflammatory state that is characteristic of an autoimmune disease like SLE, but this is not specific for NPSLE.
RESUMO
Resumen Contexto: En la práctica clínica de muchos reumatólogos y en algunos ensayos clínicos se ha usado colchicina en pacientes con osteoartritis primaria. A pesar de ello, su papel en el tratamiento de la misma no está claro y las guías no establecen recomendaciones al respecto. Objetivos: Evaluar la eficacia y la seguridad del tratamiento con colchicina en pacientes adultos con osteoartritis de rodilla, tanto primaria como asociada al depósito de cristales de pirofosfato cálcico. Métodos: Se llevó a cabo una búsqueda estructurada de la literatura utilizando las bases de datos Pubmed, Embase, Cochrane Controlled Trials Register y LILACS. Se incluyeron ensayos clínicos controlados, aleatorizados, en donde se haya usado colchicina como intervención en pacientes adultos con osteoartritis de rodilla, primaria o relacionada con pirofosfato de calcio. Resultados: Se incluyeron 5 ensayos clínicos controlados. Se observó una tendencia común en todos los estimados puntuales de los artículos a favorecer el uso de la colchicina para la mejoría del dolor y de la funcionalidad. Se observó una mayor tendencia de efectos adversos gastrointestinales con el uso de la colchicina, sin embargo, el efecto no fue estadísticamente significativo en los estudios individuales. Ninguno de los estudios evaluó calidad de vida. Conclusiones: La colchicina parece ser una alternativa eficaz y segura para el tratamiento de pacientes adultos con osteoartritis de rodilla, tanto primaria como asociada al depósito de cristales de pirofosfato de calcio. Su uso reduce el dolor y mejora la funcionalidad, aunque puede producir síntomas gastrointestinales en algunos pacientes.
Abstract Background: Colchicine is often used in patients with osteoarthritis in which calcium pyrophosphate crystal deposition disease is suspected. Colchicine has also been used by many rheumatologists in clinical practice, and in some trials, on patients with primary osteoarthritis (apparently unrelated to calcium pyrophosphate). However, its role in the treatment of primary osteoarthritis is not clear, and international guidelines have not established recommendations. Objective: To evaluate the efficacy and safety of colchicine for the treatment of adult patients with primary knee osteoarthritis as well as the form associated with calcium pyrophosphate. Methods: A structured literature search was conducted using the PubMed, Embase, Cochrane Controlled Trials Register, and LILACS databases. Randomised controlled trials were included in which colchicine was used as intervention in patients with primary or pyrophosphate calcium-associated knee osteoarthritis. Results: The study included 5 randomised controlled trials, all of which showed a common trend in all estimated points of the joint, favouring the use of colchicine for improvement in pain and functionality. Although the effect was not statistically significant in individual studies, there was a greater tendency of gastrointestinal adverse effects with the use of colchicine. None of the studies assessed quality of life. Conclusions: Colchicine appears to be an effective and safe alternative for treatment of adult patients with knee osteoarthritis, either primary or associated with the deposit of calcium pyrophosphate crystals. Its use reduces pain and improves functionality, but it can cause gastrointestinal symptoms in some patients.
