RESUMO
Introduction: Rheumatoid arthritis activity is evaluated based on a physical examination of each of the joints. However, the joint examination is not standardized, and the techniques are variable and difficult to reproduce due to disagreements among examiners. Objective: To recommend standardized joint examination techniques based on the modified RAND-UCLA appropriateness method. Methods: A review of the literature was conducted to determine the items to be included in the joint examination; subsequently, a consensus of rheumatologists was achieved with the modified RAND-UCLA methodology to issue the recommendations. The diagnosis of RA and differential diagnoses were excluded. Results: Two hundred fifteen rheumatologists were invited to participate. Five were included in the core group and 26 in the group of clinical experts. Clinical experience ranged between 2 and 25 years (mean 15.6 years; standard deviation 6.3 years). Most rheumatologists participated in all rounds (Round 1: 100%, Round 2: 61%, and Round 3: 61%). Of the 45 statements in the questionnaire assessing the examination techniques, 28 (62%) were retained. In addition, 6 other statements were included during the face-to-face meeting for a total of 34 final statements. Conclusion: Physical examination techniques for joints that determine RA activity are heterogeneous and differ markedly in terms of several characteristics. A list of recommendations is proposed as a guide to improve and standardize the method for the physical examination of the joints. This standardization will improve the diagnosis and results for patients with RA and help health caregivers provide better treatment.
RESUMO
Coronavirus disease 2019 (COVID-19) vaccines have some adverse effects, mostly mild. However, by presenting an immunological challenge to the individual, they could infrequently trigger immune-mediated diseases (IMDs). We report the case of a 42-year-old woman, with no previous medical history, who received the first dose of vaccine against COVID-19 and developed inflammatory arthralgias, associated with sudden-onset dyspnoea and hypoxemia. Pulmonary thromboembolism was documented, and the diagnosis of systemic lupus erythematosus (SLE) and secondary antiphospholipid syndrome (APS) was suspected. Autoantibodies were measured confirming this suspicion. After a few days, she presented a massive pericardial effusion with cardiac tamponade that required surgical management. Treatment with azathioprine, hydroxychloroquine, corticosteroids, and anticoagulation was indicated with improvement of all her symptoms. There is controversy regarding the potential of COVID-19 vaccines to induce autoimmunity. Studies addressing the safety of using these vaccines have reported the occurrence of mild local and systemic reactions, most frequently in young adults. So far, there are few reports of patients who have developed autoimmune or autoinflammatory diseases after getting vaccinated with any of the COVID-19 vaccines. To the best of our knowledge, to date, this is one of the first cases of new-onset SLE and secondary APS after COVID-19 vaccination.

BACKGROUND: Rheumatic diseases are a reason for frequent consultation with primary care doctors. Unfortunately, there is a high percentage of misdiagnosis. OBJECTIVE: To design an algorithm to be used by primary care physicians to improve the diagnostic approach of the patient with joint pain, and thus improve the diagnostic capacity in four rheumatic diseases. METHODS: Based on the information obtained from a literature review, we identified the main symptoms, signs, and paraclinical tests related to the diagnosis of rheumatoid arthritis, spondyloarthritis with peripheral involvement, systemic lupus erythematosus with joint involvement, and osteoarthritis. We conducted 3 consultations with a group of expert rheumatologists, using the Delphi technique, to design a diagnostic algorithm that has as a starting point "joint pain" as a common symptom for the four diseases. RESULTS: Thirty-nine rheumatologists from 18 countries of Ibero-America participated in the Delphi exercise. In the first consultation, we presented 94 items to the experts (35 symptoms, 31 signs, and 28 paraclinical tests) candidates to be part of the algorithm; 74 items (25 symptoms, 27 signs, and 22 paraclinical tests) were chosen. In the second consultation, the decision nodes of the algorithm were chosen, and in the third, its final structure was defined. The Delphi exercise lasted 8 months; 100% of the experts participated in the three consultations. CONCLUSION: We present an algorithm designed through an international consensus of experts, in which Delphi methodology was used, to support primary care physicians in the clinical approach to patients with joint pain. Key Points ⢠We developed an algorithm with the participation of rheumatologists from 18 countries of Ibero-America, which gives a global vision of the clinical context of the patient with joint pain. ⢠We integrated four rheumatic diseases into one tool with one common symptom: joint pain. It is a novel tool, as it is the first algorithm that will support the primary care physician in the consideration of four different rheumatic diseases. ⢠It will improve the correct diagnosis and reduce the number of paraclinical tests requested by primary care physicians, in the management of patients with joint pain. This point was verified in a recently published study in the journal Rheumatology International (reference number 31).

BACKGROUND: Procalcitonin (PCT), the precursor of the calcitonin, is synthesized in the parafollicular C-cells of the thyroid. It has been used to detect and to differentiate systemic bacterial infections from flares of systemic lupus erythematosus (SLE). PCT in serum increases in severe bacterial and fungal infections, but not, or only slightly in viral infections. OBJECTIVE: To measure PCT levels in patients with active SLE and to compare them with patients without lupus activity and to determine the possible association between activity and elevation of the PCT. DESIGN: Prospective case control study. PATIENT AND METHODS: Measurements were made of PCT (METHOD: Essay immunoluminometric--and ultrasensitive--BRAHMS Diagnostika, Berlin, Germany), C-reactive protein, erythrocyte sedimentation rate, and blood and urine cultures. The index of activity of SLE was determined by Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score of a serial group of patients seen by our rheumatology service. Samples from 53 patients were analyzed. The patients were divided in 2 groups: group I (n = 21) with little or no activity for SLE; group II (n = 32) with activity for SLE (SLEDAI >5). None of the patients had severe bacterial infection, sepsis, or systemic multiorgan failure. RESULTS: Group I had a SLEDAI score of 1.8 [95% confidence interval (CI) 1.09-2.51] with mean levels of PCT 0. 08 ng/mL (Negative smaller than 0. 5 ng/mL). Group II SLEDAI score was 14.6 (95% CI 11.95-17.23) with mean levels of PCT 0.418 ng/mL with standard deviation 1.0021 (95% CI 0.0628-0.773). The measure of association calculated by Fisher method was not significant (1.927) (P = 0. 282). In the group II, 3 patients had frankly positive PCT (3.18, 3.42, and 3.95 ng/mL) and high activity indices (14, 13, and 24). None presented with severe infection, sepsis, or systemic multiorgan failure. They had pneumonia, renal failure (PCT 3.42 ng/mL) and urinary tract infection without systemic symptoms (3.95 ng/mL). Infection was not detected in the other patient (3.18 ng/mL) that was interpreted as a false positive. CONCLUSIONS: This study demonstrates that there is no association between the activity of SLE and PCT levels. The utility of the PCT resides is in raising suspicion of a concurrent bacterial or mycotic infection in the evaluation of patients with active autoimmune diseases.

To summarize evidence concerning the articular examination needed to determine rheumatoid arthritis (RA) activity (follow-up or control) via a systematic review. A search of Medline, Embase, Lilacs, SciELO, the Web of Science, the National Technical Reports Library, and the reference lists of relevant studies through March 2017 was conducted using a systematic methodology to identify studies of patients with RA older than 18 years in which a detailed description of the physical examination or a description of the components of the articular examination was provided. Of 8322 references, 74 studies were included according to the selection criteria, and 6 references were ultimately included at the end of the review. Most of the included studies (n = 5) were associated with a moderate risk of bias. There was great variability among the studies and the articular examination methods used. Some studies presented the examination with a complete specification of the technique (n = 2), the consensus of rheumatologists (n = 2), or training through audiovisual materials and face-to-face courses (n = 2), but none of the studies explicitly showed the technique by which the physical examination was performed. Despite the importance of the clinical evaluation and physical examination of patients with RA for diagnosis, prognosis, clinimetrics, and follow-up, evidence concerning how to perform the articular examination is scarce.

ABSTRACT Introduction: The articular examination is an essential part of the physical examination of the patient with rheumatoid arthritis, since it gives information about the disease status at a given time and allows monitoring of its evolution over time. Despite the importance of the physical examination of the joints, it is noteworthy that there is no standardized technique. Methods: This paper aims to frame a discussion on whether standardization of the joint examination is justified, presenting arguments for and against. Results and discussion: The paper raises several arguments about diagnostic error as a scien-tific and ethical challenge in establishing the activity of rheumatoid arthritis. Conclusion: It is time to adopt a standardized physical joint examination technique that allows better assessment of the inflammatory activity status of the disease, avoids risks resultant from poor disease status classification, adheres to ethical principles and does not incur unnecessary expenses. Failure to do so would have scientific, economic, ethical, and public health implications.
R E S U M E N Introducción: El examen articular es una parte fundamental del examen físico del paciente con artritis reumatoide ya que permite obtener información sobre el estado de la enfermedad en un momento determinado, así como monitorizar su evolución en el tiempo. A pesar de la importancia del examen físico de las articulaciones, no existe una técnica estandarizada. Métodos: Este ensayo tiene como objetivo desarrollar una discusión sobre si la estandarización del examen conjunto está justificada, para lo cual se presentan argumentos a favor y en contra. Resultados y discusión: El ensayo plantea varios argumentos acerca del error diagnóstico como un desafío científico y ético cuando se trata de establecer la actividad de la artritis reumatoide. Conclusión: Es el momento de adoptar una técnica de exploración física conjunta y estandarizada, que permita una mejor valoración del estado de actividad inflamatoria de la artritis reumatoide, evite los riesgos derivados de una mala clasificación del estado de la enfermedad, respete los principios éticos y no incurra en gastos innecesarios. Dejar de hacerlo tendría implicaciones científicas, económicas, éticas y de salud pública.

RESUMEN Introducción: La percepción global de la salud (PGA) es una parte de los instrumentos compuestos utilizados para determinar la actividad de la artritis reumatoide (AR). Por lo general, se mide por medio de la escala visual análoga (EVA). En nuestra práctica clínica y en la literatura se han observado dificultades en la aplicación de la EVA. Este estudio se llevó a cabo luego de considerar la necesidad de definir el desempeño de las diferentes escalas usadas para evaluar la PGA, determinar la facilidad de su uso y proponer una nueva escala. Métodos: Se trata de un estudio basado en desenlace de pacientes con diagnóstico de AR a los que se aplicaron cuatro tipos de escalas para evaluar la PGA: escala 1 (EVA), escala 2 (escala de rostros) y una propuesta de escala visual en dos versiones: escala 3 (escala visual compuesta en orientación horizontal) y escala 4 (similar a la escala 3, pero en orientación vertical). Se analizó su correlación y la frecuencia con la que los pacientes las entendieron. Resultados: Se incluyeron 198 pacientes, 169 mujeres (85,3%) y 29 hombres (14,6%), y la edad media fue de 54,2 anos. El 59,6% de los pacientes no entendió la escala 1. La mayoría de los pacientes entendió las escalas 2, 3 y 4. Aproximadamente el 80% de los pacientes prefirió las escalas 2 (43,4%) y 3 (36,3%) (p < 0,00). Ninguna variable clínica predijo la selección de la escala. Se observó una buena correlación y una aceptable reproducibilidad de las escalas 2, 3 y 4. Conclusiones: La mayoría de los pacientes no entendió la EVA; la mayoría de nuestros pacientes entendió y prefirió las escalas propuestas, que podrían ser útiles en la práctica clínica de los pacientes con AR.
ABSTRACT Introduction: The overall perceived health (OPH) is part of the composite tools used to determine the activity of Rheumatoid Arthritis (RA). It is usually measured using a Visual Analogue Scale (VAS). Difficulties in applying the VAS have been observed in clinical practice and in the literature. This study was carried out after considering the need to define the performance of the different scales used to evaluate OPH, and determine their ease of use, as well as to propose a new scale. Methods: The study based on the outcome of patients, subjects diagnosed with RA, to whom 4 types of scales were applied to evaluate OPH: Scale 1 (VAS), Scale 2 (face scale), a proposal of a visual scale in two versions: Scale 3 (composite visual scale in horizontal orientation), and Scale 4, similar to 3 in vertical orientation. Results: Of the 198 patients included, 169 (85.3%) were women, and 29 (14.6%) were men. The mean age was 54.2 years, and 59.6% of the patients did not understand the Scale 1. The majority of the patients understood the Scales 2,3, and 4. Approximately 80% of the patients preferred the Scales 2 (43.4%) and 3 (36.3%) (P< .00), but no clinical variable predicted the selection of the scale. A good correlation and an acceptable reproducibility were observed for scales 2, 3, and 4. Conclusions: Although the majority of patients did not understand the VAS, the majority of our patients understood and preferred the proposed scales that could be useful in the clinical practice of RA patients.

Resumen La psoriasis es una enfermedad cutánea común, con prevalencia mundial entre el 0,9-8,5%. Es una condición inflamatoria crónica, inmunológicamente mediada, que lleva a hiperplasia epidérmica con gran variedad de formas clínicas. La psoriasis ostrácea es una variante hiperqueratósica infrecuente, reportada pocas veces en la literatura y que con frecuencia se asocia a artritis psoriásica, una artropatía inflamatoria, seronegativa, crónica, cuyos síntomas usualmente comienzan después de las lesiones cutáneas. Este es el caso de un paciente con una presentación inusual de artritis psoriásica asociada a psoriasis ostrácea posterior a 10 arios de manejo adecuado con infliximab.
Abstract Psoriasis is a common cutaneous disease with a world prevalence of 0.9-8.5%. It is a chronic, inflammatory, immune mediated condition that leads to epidermal hyperplasia and an array of clinical presentations. Psoriasis ostracea is a rare hyperkeratotic variant of psoriasis. Although frequently associated with psoriatic arthritis, there are few reports in the literature. Psoriatic arthritis is a chronic, seronegative, inflammatory arthritic disease, in which the symptoms usually emerge years after skin lesions appear. The case is presented of a patient, who after 10-years of adequate Infliximab treatment, had an unusual presentation of psoriatic arthritis associated with psoriasis ostracea.

RESUMEN La proliferación del tejido sinovial, que es llamada pannus, se ha considerado como una manifestación tardía, inactiva e irreversible de la artritis reumatoide (AR), contrario a lo que históricamente se ha estudiado. Se realizó una búsqueda de la literatura para realizar una revisión narrativa e histórica respecto al surgimiento del término pannus y su papel en la artritis reumatoide. Estudios de microscopia de luz han mostrado el carácter destructivo de este tejido con hallazgos característicos de la AR, corroborados con microscopia electrónica arios más tarde. Estos hallazgos llevaron a caracterizar el componente celular del pannus con gran número de células inmunológicas y de líneas celulares específicas con propiedades especiales como los sinoviocitos similares a fibroblastos. Este componente celular es el origen de una gran cantidad de citoquinas y proteinasas que perpetúan y causan el daño óseo y del cartílago. Este componente inflamatorio ha sido evidente también con el desarrollo de técnicas de imágenes, como la resonancia magnética y la ultrasonografía, que muestran un papel activo del tejido sinovial engrosado, junto a la hipervascularización en el daño articular y la reversibilidad de estos cambios tras el tratamiento. Las evidencias contempladas permiten concluir que el pannus como evidencia histológica (más que clínica) se refiere a la proliferación del tejido sinovial e incluye un gran componente celular activo que genera y perpetúa la inflamación y, por tanto, la enfermedad.
ABSTRACT Pannus refers to synovial tissue proliferation, and has been considered a late, inactive and irreversible manifestation of rheumatoid arthritis (RA), contrary to historical findings. A literature search was performed on terminology about pannus and its historical role in the pathophysiology of RA. Light microscopy studies have shown the destructive impact of pannus tissue with very specific abnormalities, corroborated a year later with electronic microscopy. Some of these findings are the isolation of the immunological cells inside the tissue, especially one cell line with particular capacities, called synoviocytes similar to fibroblasts. This cellular component is the source a large quantity of cytokines and proteinases that perpetuate and cause bone and cartilage damage. Inflammation has been seen in many image techniques, such as magnetic resonance and ultrasound. These show the role of tissue widening and hyper-vascularization in tissue damage, and some reversibility after treatment of RA. With the evidence presented it is possible to conclude that pannus refers to a histological (more than clinical) term for synovial hypertrophy, and includes a large component of cell activity that generates and perpetuates inflammation and thus the disease.

ABSTRACT Introduction: Post-chikungunya virus (CHIKV) chronic arthritis is a common complication of the acute infection caused by this virus, with high risk of progression to functional and quality of life sequelae. Objective: To identify the clinical and immunological characteristics, functional disabilities, and quality of life decline in a sample of Colombian patients with chronic arthropathy associated with chikungunya virus (CHIKV). Methods: A group of 94 patients was evaluated in a City in Colombia during the CHIKV epidemics from 2014 to 2015. Results: The mean age of the 94 patients was 57 years; 76% were women, and 100% came from low socioeconomic groups. Typically, the joint disease was symmetrical, with joint swelling present in 30% of the cases, mostly involving the small and large joints of the upper limbs. Rheumatoid factor was positive in 1.06% and anti-citrulline antibodies in 0%. There were detectable levels of IL6 in 64.9%, and IL 17 in 7.45% of the patients. The severity of disease activity was determined using the DAS28 score, identifying 55.3% with moderate activity, 40.4% with mild activity, and 4.2% with high activity. The HAQ-DI identified a moderate functional limitation in 45.7% of the cases, with a mean score of 1.02. The quality of life measured with the SF-36 scale showed that all of the domains evaluated were affected but pain and the physical and emotional domains were significantly more affected. Conclusions: Patients with post-chikungunya chronic arthritis, presented in most cases arthralgia, arthritis, functional impairment, and poor quality of life. It is then necessary to adopt comprehensive therapeutic measures for a sound intervention of this pathology.
RESUMEN Introducción: La artropatía por virus de chikungunya (CHIKV) es una complicación frecuente secundaria a la infección inicial por este virus con un alto riesgo de progresión a secuelas funcionales y de calidad de vida. Objetivo: Identificar las características clínicas, inmunológicas, de discapacidad funcional y de deterioro de la calidad de vida en una muestra de pacientes colombianos con artropatía crónica por CHIKV. Métodos: Se evaluó un grupo de 94 pacientes en una ciudad colombiana durante la epidemia por CHIKV en el periodo 2014-2015. Resultados: En los 94 pacientes la edad media fue de 57 años, siendo el 76% mujeres y el 100% de la población afectada perteneció a estratos socioeconómicos bajos. El cuadro articular característicamente fue simétrico con inflamación articular en el 30%, mayor compromiso de articulaciones grandes y pequeñas de miembros superiores. Se identificó positividad para factor reumatoide en el 1,06%, anticuerpos anticitrulina en el 0%, niveles detectables de IL-6 en el 64,9% y de IL-17 en el 7,45% de los pacientes. La severidad de la actividad articular se exploró con la escala DAS28, identificando un 55,3% con actividad moderada, un 40,4% actividad leve y un 4,2% con actividad alta. El HAQ-DI identificó un compromiso funcional moderado en el 45,7%, con puntaje medio de 1,02. La calidad de vida medida con la escala SF-36 mostró que todos los dominios evaluados fueron afectados con mayor compromiso de los dominios dolor, rol físico y rol emocional. Conclusiones: En los pacientes afectados por artropatía crónica por CHIKV se observó artralgias, artritis, deterioro funcional y de la calidad de vida en la mayoría de la población estudiada, por lo que es necesario adoptar medidas terapéuticas en todos estos niveles para una intervención adecuada en esta patología.

RESUMEN El lupus eritematoso sistémico se puede presentar con un amplio espectro de síntomas que en algunas ocasiones pueden enmascarar complicaciones graves asociadas a la misma enfermedad. Dentro de estas la pancreatitis es una causa poco común, y sin embargo de alta mortalidad, especialmente en pacientes con un tratamiento no oportuno. Reportamos el caso de una paciente que cursa con lupus eritematoso sistémico con compromiso renal y de sistema nervioso central, de reciente aparición, que se asocia a la aparición de pancreatitis y tiroiditis, presentando evolución satisfactoria con esquema terapéutico de ciclofosfamida y prednisolona.
ABSTRACT Systemic lupus erythematosus can present with a broad spectrum of symptoms that on some occasions may mask serious complications associated with the same disease. Within these, pancreatitis is an uncommon but high-mortality cause, especially in patients with non-oportune treatment. We report the case of a patient with systemic lupus eryt-hematosus with recent renal and central nervous system involvement that is associated with the onset of pancreatitis and thyroiditis. A satisfactory outcome was obtained with a cyclophosphamide and prednisolone therapeutic regimen.

(AU) El concepto de «riesgo en salud¼ es relativamente nuevo, surge en el lenguaje epidemiológico británico en los inicios del siglo xx y es definido por la OMS como la probabilidad de un resultado sanitario adverso, o la presencia de un factor que aumenta esa probabilidad. La gestión del riesgo se define, a su vez, como el proceso de identificar, analizar y cuantificar las probabilidades de pérdidas y efectos secundarios que se desprenden de los actos en salud, así como de las acciones preventivas, correctivas y reductivas correspondientes que deben emprenderse. La gestión del riesgo es un proceso gerencial estructurado que tiene por objetivo identificar los principales riesgos en salud de la población o del individuo. Los riesgos identificados son intervenidos mediante estrategias coordinadas que buscan disminuir su ocurrencia

Lupus panniculitis or lupus profundus is a variant of lupus Erythematosus cutaneous that primarily affects subcutaneous tissue. Clinically, it is characterized by one or several firm subcutaneous nodules and/or plaques with or without overlying epidermal changes. It is reported to occur with a frequency of 2-3% in patients with Systemic Lupus Erythematosus (SLE). Between 10 and 50 percent of patients with lupus panniculitis will have or eventually develop Systemic Lupus Erythematosus. In nearly all cases there are deep, erythematosus plaques and nodules, and some of them ulcers, which usually involve the proximal extremities, trunk, breasts, buttocks, and face. These lesions may be tender and painful and frequently heal with atrophy and scaring, turning as a chronic condition and subsequently heal with disfigurement. We describe a patient who suffers from lupus panniculitis with no association to SLE symptoms and complicated by several progressive and disabling cutaneous lesions.
La paniculitis lúpica o también llamada lupus profundus es una variante del lupus eritematoso cutáneo que afecta el tejido celular subcutáneo. Se caracteriza clínicamente por uno o varios nódulos subcutáneos que son firmes y/o placa con o sin cambios epidérmicos. Se ha informado su frecuencia en 2% a 3% de casos de Lupus eritematoso sistémico. Entre el 10 al 50% de los casos de paniculitis lúpica va a desarrollar lupus eritematoso sistémico. En casi todos los casos hay placas eritematosas y/o nódulos que en algunos casos se ulceran y que usualmente están localizados en las áreas proximales de las extremidades, tronco, mamas, nalgas y la cara. Estas lesiones pueden ser clínicamente dolorosas y sensibles a la presión y frecuentemente cicatrizan con desfiguración del área circundante. Describimos un paciente que padece de paniculitis lúpica sin asociación de lupus eritematoso sistémico y que se complicó con varias lesiones cutáneas progresivas y discapacitantes.

Introducción: la esclerodermia es una alteración autoinmune caracterizada por induración y engrosamiento de la piel. Durante el curso de la enfermedad los pacientes pueden padecer síntomas de afectación musculoesquelética que incluyen artralgias, artritis, pérdida de función articular y discapacidad consecuente. Objetivos: se estudió la relación de las manifestaciones osteo-articulares clínicas y radiológicas con los anticuerpos anti-péptido citrulinado en una cohorte de pacientes con esclerodermia. Materiales y métodos: se evaluó la historia clínica de pacientes con esclerodermia buscando datos con características de la enfermedad, afectación de órgano blanco y síntomas osteo-articulares. A todos los pacientes se les realizó anticuerpos anti-péptido citrulinado de tercera generación y se les tomó radiografía de manos y pies. Resultados: se incluyeron en forma consecutiva 123 pacientes y se analizaron los datos de 100 pacientes. Ochenta y cuatro pacientes con esclerodermia limitada y 16 con esclerodermia difusa. El promedio de edad fue de 55,5 años y la mediana del tiempo de diagnóstico correspondió a 6,9 años. Catorce pacientes presentaron anticuerpos anti-péptido citrulinado positivos (14%), 4 pacientes con esclerodermia difusa y 9 pacientes con esclerodermia limitada. Dieciocho pacientes (18%) presentaron el factor reumatoide IgM positivo y no se observó relación entre la afectación de órgano blanco con los anticuerpos. El 72% de los pacientes presentaron síntomas osteo-articulares, 17 de ellos presentaron artralgias (23,6%). La combinación de artralgias y artritis se observó en 25 (34,7%) de los pacientes. Artralgias, artritis y contracturas en 10 (13,9%) pacientes. Dos pacientes presentaron artritis (2,8%), 3 contracturas (4,2%) y 5 calcinosis (6,9%). Analizando la asociación entre los anticuerpos antiCCP y la afectación clínica articular, no se encontró asociación estadísticamente significativa (p= 0,095). En el análisis radiológico se observó: En las manos con mayor frecuencia resorción ósea u osteolisis (72%). También se observó calcinosis (54%), aumento de tejidos blandos (49%) y contracturas en flexión (31%). En los pies se observó con mayor frecuencia resorción falángica u osteolisis (13%). Además calcinosis (10%), disminución del espacio articular (6%). Se evidenció una asociación de calcinosis con los antiCCP positivos. Conclusión: los hallazgos articulares fueron frecuentes en esta cohorte de pacientes con esclerodermia. La prevalencia de los anticuerpos antiCCP y factor reumatoide fueron de alrededor del 15%. Se observó más alteraciones radiológicas en las manos que los pies probablemente por factores mecánicos. Se observó una asociación de calcinosis en las manos con los antiCCP.
Introduction: scleroderma is an autoimmune disease characterized by induration and thickening of skin. Patients may suffer from musculoskeletal symptoms which include arthralgias, arthritis, loss of articular function and disability. Objectives: we sought to assess any association between radiographic features, osteoarticular manifestations, and anti-CCP antibodies in a cohort of scleroderma patients. Materials and methods: we evaluated the clinical features of patients searching for demographic characteristics, organ system involvement and osteoarticular symptoms. The presence of anti-CCP IgG was evaluated in all patients. Standard radiographs of hands and feet were taken and analyzed. Results: one hundred twenty three consecutive patients were included and 100 patients were analyzed in the present study. Eighty four patients had limited scleroderma and 16 patients had diffuse scleroderma. The mean age was 55.5 years and the median time of diagnostic was 6.9 years. Fourteen patients were positive for presence of anti-CCP (14%), 4 patient for diffuse form and 9 patients for limited form. Eighteen patients were positive for IgM rheumatoid factor test (18%). It was not seen an association between organ involvement and antibodies. Seventy two percent of patients showed osteoarticular symptoms, 17 of them had arthralgias (23.6%), 25 had arthralgias and arthritis (34.7%), and 10 had arhtralgias, arthritis and contractures (13.9%). Two patients showed arthritis (2.8%), three contractures (4.2%) and 5 calcinosis (6.9%). There was no association between the presence of anti-CCP antibodies and osteoarticular manifestations (p= 0.095). Radiographic features seen on hands were osteolysis (72%), calcinosis (54%), increasing of soft tissues (49%) and flexion contractures (31%). On feet was seen osteolysis (13%), calcinosis (10%) and decreasing of articular space (6%). There was association between calcinosis and anti-CCP antibodies. Conclusion: the articular findings were frequently seen in this scleroderma cohort. Prevalence of anti-CCP antibodies and rheumatoid factor was around 15% positive. Hands showed more alterations than feet, probably for mechanistic factors. It was seen an association between hand calcinosis and anti-CCP antibodies.

Los síndromes paraneoplásicos neurológicos (SPN) comprometen el sistema nervioso (central periférico o neuromuscular) de forma focal o difusa y se deben a una respuesta inmune de tipo humoral o celular sin que haya metástasis o extensión directa del tumor, su incidencia es baja. El SPN hace que el sistema inmune medie su respuesta a través de las células T principalmente cuando los antígenos son de localización intracelular, pero cuando los antígenos se localizan en la membrana celular se ha observado una mediación por anticuerpos.Los SPN pueden preceder la aparición de un tumor. Los anticuerpos onconeuronales permiten limitar su espectro diferencial y facilitan el diagnóstico y tratamiento tempranos. Los síndromes neurológicos no paraneoplásicos y sin un tumor subyacente son entidades importantes para el diagnóstico diferencial, en ellos hay una mediación por anticuerpos contra las proteínas sinápticas y de la superficie celular y comparten características clínicas con los SPN; afectan niños y adultos jóvenes y pueden responder a inmunoterapia.El objetivo de este artículo es explorar las características de los SPN y los mecanismos inmunológicos que los identifican, definir los anticuerpos mejor estudiados y presentar un plan de diagnóstico y tratamiento.
