OBJECTIVE: To evaluate the association between patients' characteristics and disease activity in an Argentine lupus registry. METHODS: Cross-sectional study. Disease activity was stratified into: Remission off-treatment: SLEDAI = 0, without prednisone and immunosuppressive drugs. Low disease activity Toronto Cohort (LDA-TC): SLEDAI ≤2, without prednisone or immunosuppressive drugs. Modified lupus low disease activity (mLLDAS): SLEDAI score of ≤4, with no activity in major organ systems and no new features, prednisone of ≤10 mg/day and/or immunosuppressive drugs (maintenance dose) and Active disease: SLEDAI score of >4 and prednisone >10 mg/day and immunosuppressive drugs. A descriptive analysis and logistic regression model were performed. RESULTS: A total of 1346 patients were included. Of them, 1.6% achieved remission off steroids, 0.8% LDA-TC, 12.1% mLLDAS and the remaining 85.4% had active disease. Active disease was associated with younger age (p ≤ 0.001), a shorter time to diagnosis (p ≤ 0.001), higher frequency of hospitalizations (p ≤ 0.001), seizures (p = 0.022), serosal disease (p ≤ 0.001), nephritis (p ≤ 0.001), higher SDI (p ≤ 0.001), greater use of immunosuppressive therapies and higher doses of prednisone compared to those on mLLDAS. In the multivariable analysis, the variables associated with active disease were the presence of pleuritis (OR 2.1, 95% CI 1.2-3.9; p = 0.007), persistent proteinuria (OR 2.5, 95% CI 1.2-5.5; p ≤ 0.011), nephritis (OR 2.5, 95% CI 1.2-5.6; p = .018) and hospitalizations (OR 8.9, 95% CI 5.3-16.0; p ≤ 0.001) whereas age at entry into the registry was negatively associated with it (OR 0.9, 95% CI 0.9-1.0; p = 0.029). CONCLUSION: Active disease was associated with shorter time to diagnosis, worse outcomes (SDI and hospitalizations) and renal, neurological and serosal disease.

Resumen Introducción: el progreso en los tratamientos para el lupus eritematoso sistémico (LES) resultó en una disminución de la mortalidad; sin embargo, la enfermedad cardiovascular y las complicaciones infecciosas aún son las principales causas de muerte. La evidencia apoya la participación del sistema inmunológico en la generación de la placa aterosclerótica, así como su conexión con las enfermedades autoinmunes. Objetivos: describir la frecuencia de eventos cardiovasculares (ECV) en el Registro de Lupus Eritematoso Sistémico de la Sociedad Argentina de Reumatología (RELESSAR) transversal, así como sus principales factores de riesgo asociados. Materiales y métodos: estudio descriptivo y transversal para el cual se tomaron los pacientes ingresados en el registro RELESSAR transversal. Se describieron las variables sociodemográficas y clínicas, las comorbilidades, score de actividad y daño. ECV se definió como la presencia de al menos una de las siguientes patologías: enfermedad arterial periférica, cardiopatía isquémica o accidente cerebrovascular. El evento clasificado para el análisis fue aquel posterior al diagnóstico del LES. Se conformaron dos grupos macheados por edad y sexo 1:2. Resultados: 1515 pacientes mayores de 18 años participaron del registro. Se describieron 80 pacientes con ECV (5,3%). En este análisis se incluyeron 240 pacientes conformando dos grupos. La edad media fue de 47,8 (14,4) y 47,6 (14,2) en el grupo con y sin ECV respectivamente. Los pacientes con ECV tuvieron mayor duración del LES en meses, mayor índice de Charlson, mayor SLICC (Systemic Lupus International Collaborating Clinics/American College of Rheumatology), mayor frecuencia de manifestaciones neurológicas, síndrome antifosfolípido, hospitalizaciones y uso de ciclofosfamida. Las únicas variables asociadas en el análisis multivariado fueron el índice de Charlson (p=0,004) y el SLICC (p<0,001). Conclusiones: los ECV influyen significativamente en nuestros pacientes, y se asocian a mayor posibilidad de daño irreversible y comorbilidades.
Abstract Introduction: progress in treatments for systemic lupus erythematosus (SLE) has resulted in a decrease in mortality; however, cardiovascular and infectious diseases remain the leading causes of death. Evidence supports the involvement of the immune system in the generation of atherosclerotic plaque, as well as its connection to autoimmune diseases. Objectives: to describe the frequency of cardiovascular disease (CVD) in the cross-sectional RELESSAR registry, as well as its associated variables. Materials and methods: a descriptive and cross-sectional study was performed using patients admitted to the cross-sectional RELESSAR registry. Sociodemographic variables, clinical variables, comorbidities, activity and damage scores were described. CVD was defined as at least one of the following: peripheral arterial disease, ischemic heart disease, or cerebrovascular accident. All patients with at least one CVD were included in our analysis (heart attack, central nervous system vascular disease, and peripheral arteries atherosclerotic disease). The event classified for the analysis was that after the diagnosis of SLE. SLE diagnosis was previous to CVD. Two groups matched by age and sex, 1:2 were formed. Results: a total of 1515 patients older than 18 years participated in the registry. Eighty patients with CVD (5.3%) were described in the registry. Two-hundred and forty patients were included, according to two groups. The mean age was 47.8 (SD 14.4) and 47.6 (SD 14.2) in patients with and without CVD, respectively. Patients with CVD had a longer duration of SLE in months, a higher Charlson index, a higher SLICC, increased frequency of neurological manifestations, antiphospholipid syndrome, hospitalizations, and use of cyclophosphamide. The associated variables in the multivariate were the Charlson Index (p=0.004) and the SLICC (p<0.001). Conclusions: CVDs have a significant influence on our patients, being associated with a greater possibility of damage and comorbidities.

The case is presented on a 52-year-old male patient, who was seen in the Rheumatology department. He had painless lymph nodes in the cervical, axillary, supraclavicular, and neck region. He also had a fever, and parotid and submaxillary gland enlargement. Complementary studies were performed, showing normocytic-normochromic anemia, thrombocytopenia and eosinophilia, impaired renal function with hypoalbuminaemia and hematuria, ANA 1/5120, Sm+, ACL+. Biopsies were also performed on the compromised tissues, reaching the diagnosis of Rosai-Dorfman Disease and IgG4-related Disease. Differential diagnoses of cervical, axillary and inguinal lymph nodes, with fever, renal and hematological compromise are discussed.

OBJECTIVE: The objective is to describe the main characteristics of patients with systemic lupus erythematosus (SLE) in Argentina and to examine the influence of ethnicity on the expression of the disease. PATIENTS AND METHODS: RELESSAR is a multicentre register carried out by 106 researchers from 67 rheumatologic Argentine centres. It is a cross-sectional study of SLE (1982/1997 ACR) patients. RELESSAR electronic database includes demographic, cumulative SLE manifestations, SELENA-SLEDAI, SLICC-SDI, Katz's severity and Charlson's comorbidity indexes and treatment patterns. RESULTS: We included 1,610 patients, 91.7% were female with a median age at diagnosis of 28.1 ± 12.8; 96.2% met ≥4 ACR 1982/97 criteria. Frequent manifestations were arthritis (83.5%), malar rash (79.5%), photosensitivity (75.3%), haematological (63.8%) and renal disease (47.4%), antinuclear antibodies (96%), anti-dsDNA (66.5%) and anti-Smith antibodies (29%). The mean Selena-SLEDAI score at last visit was 3.18 (SD 4.3) and mean SDI was 1 (SD 1.3). The accumulated treatments most frequently used were antimalarials (90.4%), corticosteroids (90%), azathioprine (31.8%), intravenous cyclophosphamide (30.2%), mycophenolate mofetil or mycophenolic acid (24.5%), methotrexate (19.3%), belimumab 5.3% and rituximab 5.1%. Refractory lupus was diagnosed in 9.3% of the cases. The main causes of death were lupus activity (25.0%), activity and concomitant infections (25.0%), infections (18.2%), vascular disease (13.6%) and cancer (4.5%). Mortality was associated with higher SLEDAI, Katz, damage indexes and comorbidities. Of the 1610 patients included, 44.6% were Caucasian, 44.5% Mestizo, 8.1% Amerindian and 1.2% Afro-Latin American. Mestizo patients had higher male representation, low socioeconomic status, more inadequate medical coverage, fewer formal years of education and shorter disease duration. Polyadenopathies and Raynaud's phenomenon were more frequent in Caucasians. In the logistic regression analysis higher damage index (OR 1.28, CI 95% 1.02-1.61, p = 0.03) remained associated to mestizo ethnicity. CONCLUSIONS: This study represents the largest number of adult patients with SLE studied in Argentina. Caucasian patients were differentiated by having Raynaud's phenomenon and polyadenopathy more frequently, while patients of Mestizo origin had higher damage indexes.

Introducción: el lupus es una enfermedad compleja y varias veces de difícil abordaje. Alcanzar la remisión es uno de los objetivos, incorporando opciones terapéuticas. Objetivos: describir las características generales de los pacientes según el estado de la enfermedad y el uso de belimumab. Materiales y métodos: estudio de corte transversal, registro RELESSAR. Se definió el estado de la enfermedad como: remisión: SLEDAI=0 y sin corticoides; baja actividad de la enfermedad: SLEDAI >0 y ≤4 y sin corticoides; control no óptimo: SLEDAI >4 y cualquier dosis de corticoides. Resultados: se incluyeron 1.277 pacientes, 23,4% en remisión, 12,6% en baja actividad y 63,8% con control no óptimo. En este último grupo eran más jóvenes y con menor duración de la enfermedad; presentaban mayores índices de actividad y cronicidad, y mayor empleo de inmunosupresores. Solo el 22,3% de los pacientes con criterio potencial de uso de belimumab (lupus eritematoso sistémico activo a pesar del tratamiento estándar) lo recibía en ese momento. Las variables asociadas a hospitalizaciones fueron: terapia con corticoides, ciclofosfamida y mayor SLICC. Conclusiones: se refleja la complejidad del manejo de estos pacientes y se visualizan aspectos estructurales como la desigualdad. El uso del belimumab resultaría beneficioso en los pacientes seleccionados.
Introduction: lupus is a complex disease and often difficult to approach. Achieving remission is one of the objectives, incorporating therapeutic options. Objectives: to describe the characteristics of the patients and the use of belimumab, according to the status of the disease. Materials and methods: cross-sectional study. Patients of the RELESSAR registry. Stratification: Remission: SLEDAI=0 and without corticosteroids. Low disease activity SLEDAI> 0 and ≤4 and without corticosteroids and non-optimal control: SLEDAI> 4 and any dose of corticosteroids. Results: a total of 1,277 patients were included, 23.4% in remission, 12.6% in low disease activity and 63.8% in non-optimal control. The last group was younger and had a shorter duration of the disease. They had higher activity and chronicity indices and greater use of immunosuppressants. Only 22.3% of the patients with potential criteria for the use of belimumab (activity disease despite standard treatment) were receiving it. The variables associated with hospitalizations were: corticosteroids, cyclophosphamide and higher SLICC. Those associated with severe infection: mycophenolate mofetil, azathioprine, corticosteroids, and higher SLICC. Conclusions: the complexity of the management of these patients is reflected, visualizing structural aspects such as inequality. The use of belimumab could be beneficial in selected patients.

INTRODUCTION: Pulmonary haemorrhage (PH) in systemic lupus erythematosus (SLE) is a rare but potentially fatal complication due to its high mortality. Early treatment benefits the outcome. Reports on predictive factors of PH in SLE patients are scarce. OBJECTIVE: To describe a case series of PH in SLE patients that were attended in the Rheumatology Section of the J. M. Cullen Hospital and to compare this data with published results. METHODS: Patients with SLE (1982-1997 ACR criteria) and PH diagnosed by clinical criteria (cough, dyspnoea, haemoptysis), haemoglobin below 12â¯g/dL or drop greater than 2 points, new radiological infiltrate and bronchioalveolar lavage, monitored between June 1987 and December 2019 were studied. Demographic, clinical, laboratory, treatment and prognosis data related to PH were analysed. RESULTS: From a database of 306 SLE patients, 25 (8.2%) developed 29 episodes of PH. PH was the first manifestation of SLE in 8 patients. Renal involvement was the most frequent manifestation prior to the development of PH. SLE activity (measured by SLEDAI) was high during the episodes (mean: 16.8). Renal failure (pâ¯=â¯.027) and mechanical respiratory support (pâ¯=â¯.006) were related to mortality (40.7%) with statistical significance. Patients with SLEDAI higher to 10 at SLE onset showed more likelihood of developing PH. The OR was 2.68 (pâ¯=â¯.046). CONCLUSIONS: Although treatment in SLE has progressed in recent years, PH continues to be a rare and severe complication of this disease. When a PH is suspected, studies to confirm it must be done rapidly, since early diagnosis and aggressive treatment have been shown to improve survival. We observed that patients with renal involvement and mechanical respiratory support had higher mortality than SLE patients without them.

Introducción: La hemorragia alveolar difusa (HAD) es una complicación infrecuente pero grave en pacientes con Lupus eritematoso sistémico (LES). Su tratamiento debe ser precoz, lo cual mejora la supervivencia. Las comunicaciones de factores predictores de HAD en pacientes con LES son escasas. Objetivo: Describir una serie de casos de HAD en pacientes con LES, del Servicio de Reumatología del Hospital J.M. Cullen, de Santa Fe, y compararlos con un grupo control de pacientes con LES del mismo Servicio y con los datos de la literatura. Material y métodos: Se incluyeron pacientes con LES (Criterios ACR 1982-1997) y HAD definida por parámetros clínicos (tos, disnea, hemoptisis), analíticos (caída de la hemoglobina por debajo de 12 g/dL o mayor a dos puntos respecto del basal en pacientes ya conocidos), imagenológicos (infiltrado radiológico y/o tomográfico bilateral o difuso) y lavado bronquioalveolar (BAL) (retorno sanguinolento en el lavado, más de 20% de siderófagos, sin evidencia de lesiones sangrantes), quienes concurrieron al servicio entre junio de 1987 y diciembre de 2019. Se analizaron datos demográficos, clínicos, de laboratorio, tratamientos y pronóstico de los pacientes. Resultados: Se trabajó con una base de datos de 306 pacientes con diagnóstico de LES, evaluándose 25 de ellos (8,2%) que presentaron 29 episodios de HAD (ocho de ellos como forma de inicio de la enfermedad). El compromiso renal fue el más frecuentemente asociado a la HAD (previo o concomitantemente). La actividad de la enfermedad medida por SLEDAI fue alta durante el episodio, y su media fue de 16,8 puntos. En todos los casos se constató sangrado pulmonar por BAL o tubo endotraqueal. Se halló significación estadística al relacionar la mortalidad (40,7%) con requerimiento de asistencia respiratoria mecánica (ARM) (p = 0,006) y falla renal (p = 0,027). Los pacientes con SLEDAI mayor a 10 al inicio de la enfermedad presentaron más posibilidades de desarrollar HAD (OR = 2,68, p = 0,046).(AU)

ABSTRACT Cocaine use is associated with several rheumatic syndromes. A series of cases is presented of 10 patients (7 male and 3 female), age at onset: 19-38 years-old. They consulted due to a variety of symptoms: fever, arthritis, swollen hands, stroke, fetal losses, arterial hypertension, alveolar hemorrhage, leucocytoclastic vasculitis, genital bleeding, among others. Half of them showed positive ANA and Ro antibodies, lymphopenia and positive P-ANCA. Treatments with steroids in bolus, cyclophosphamide and rituximab were used, with a good response. This series highlights clinical manifestations at onset that can mimic primary rheumatic diseases. Rheumatologists should consider cocaine use in the differential diagnoses of vasculitis and pseudovasculitis syndromes.
RESUMEN El uso de cocaína se asocia con varios síndromes reumáticos. Se trata de 10 pacientes (7 varones y 3 mujeres) con una edad al inicio del cuadro entre 19-38 anos, quienes consultaron por una variedad de síntomas: fiebre, artritis, tumefacción de manos, accidente isquémico transitorio, pérdidas fetales, hipertensión arterial, hemorragia alveolar, vasculitis leucoci-toclástica y hemorragia genital, entre otros. La mitad de estos pacientes presentaron ANA y anticuerpo anti-Ro positivos, linfopenia y p-ANCA positivo. Fueron tratados con corticoides intravenosos en bolo, ciclofosfamida y rituximab, con buena respuesta. Esta serie resalta las manifestaciones clínicas que, al inicio del cuadro, pueden imitar una enfermedad reumática primaria. Los reumatólogos debieran considerar a la cocaína en el diagnóstico diferencial de las vasculitis y los síndromes seudovasculíticos.

Estudios recientes sobre lupus eritematoso sistémico (LES) han comunicado desenlaces más favorables gracias al mejor conocimiento de la enfermedad, al manejo más experto del mismo y al uso racional de los tratamientos. En este estudio se identificaron 301 pacientes con lupus eritematoso sistémico (LES), vistos entre 1988 y 2019. Doscientos veintiocho fueron tratados en el sistema público de salud y 73 en el sistema privado. Ambos grupos fueron comparados, observando que los primeros tenían menor edad al momento de la primera consulta y al inicio del LES y menor tiempo de evolución hasta la primera consulta que los pacientes atendidos en el sistema privado de salud de manera estadísticamente significativa. También mostraron mayor frecuencia de leucopenia, con presencia de anticuerpo Sm y compromiso renal en la primera consulta, como así también mayor uso de corticoides EV. Los pacientes hospitalarios presentaron mayor daño acumulado en los primeros 10 años de evolución, pero el desenlace muerte fue similar en ambos grupos. Ambos grupos de pacientes (tanto los del sistema público como los del sector privado) fueron atendidos por especialistas, realizando un cuidadoso seguimiento de estos pacientes.
Recent studies on systemic lupus erythematosus (SLE) have reported more favorable outcomes thanks to better knowledge of the disease, more expert management of it, and rational use of treatments. In this study we identified 301 SLE patients, seen between 1988 and 2019. Two hundred and twenty eight patients were treated in the public health system and 73 in private practice. In comparing both groups, we discovered that patients in the public health system were younger at first consultation and at SLE onset and that the mean duration of their disease prior to first consultation was shorter in a statistically significant way. Also, they showed more frequence of leucopenia, Sm antibody, renal involvement and received I.V. corticosteroids. Patients treated in the public system of health showed more accrual damage over the 10 first years of the disease than patients seen in the private system of health, but death in both groups was similar. Patients from both public and private groups were attended by medical specialist practices who made close follow-ups.

La enfermedad de Erdheim-Chester (EEC) es una histiocitosis de células no Langerhans de presentación proteiforme y escaso conocimiento. Se presenta una serie de 19 casos de 4 centros, registrados de junio de 2012 a junio de 2019. Se incluyeron aquellos pacientes con clínica, anatomía patológica e inmunohistoquímica característica de la enfermedad. Se excluyeron pacientes con hallazgos indefinidos. Resultados: al igual que en la literatura, el compromiso más frecuente fue el óseo por imagenología, la mitad de estos sintomático. Nuestra serie presenta mayor incidencia de mujeres (casi 70%). Siete pacientes presentaron nódulo mamario como forma de presentación. La mayoría recibieron dosis media de esteroides asociado a otra droga inmunosupresora. La mortalidad fue del 16%. Conclusión: comunicamos una serie de pacientes con la EEC mencionando las características más destacables. Es llamativo el número de pacientes con afectación mamaria, por lo cual proponemos téngase en cuenta en el diagnóstico diferencial de la patología tumoral mamaria.
Erdheim-Chester disease (ECD) is a non-Langerhans histiocytosis, protein manifestations at start and little known. We included 19 patients from June 2012 to June of 2019. Inclusion criteria: clinical features, histopathology and immunostaining compatible with ECD. We excluded patients with undefined features. Results: Bones were the most frequent affected, half of them were asymptomatic. Seventy per cent of the patients were women, and 7 of them developed a nodule breast as first manifestation of ECD. The patients were treated with corticosteroids associated or not with immunosuppressants. The mortality rate was 16%. Conclusion: We reported a series of patients with ECD, enhancing the most frequent features. It is striking the number of patients with breast involvement; we propose to include the Erdheim-Chester disease in differential diagnosis of breast tumor.

Las gammapatías monoclonales son un grupo amplio de enfermedades de células hematológicas con expresión clínica variable, con afectación sistémica o localizada. Muchos de estos trastornos simulan enfermedades reumáticas, y pueden presentarse previa- o posteriormente a la enfermedad de base, por lo cual dificultan su diagnóstico. El propósito de este estudio es comunicar los casos de cinco pacientes con manifestaciones clínicas de enfermedades reumáticas y diagnóstico final de enfermedades oncohematológicas. Se realizó un estudio descriptivo transversal mediante el análisis de historias clínicas de pacientes evaluados en el Servicio de Reumatología del Hospital José María Cullen de Santa Fe entre marzo del 2010 y junio del 2019. Se incluyó a cinco pacientes que fueron estudiados por sospecha de enfermedad reumatológica hasta llegar al diagnóstico final de gammapatía monoclonal. Cuatro pacientes presentaron mieloma múltiple manifestado como síndrome de Schnitzler; xantogranuloma del adulto y amiloidosis; aplastamientos vertebrales múltiples; falla renal aguda, respectivamente. El quinto paciente se presentó simulando una vasculitis sistémica con afectación multiorgánica y diagnóstico final de linfoma intravascular. Los pacientes fueron derivados al Servicio de Oncología y Hematología para su atención. A partir de la serie de casos analizados, se concluye que las manifestaciones reumáticas de las enfermedades oncohematológicas se deben tener presentes en el accionar diario para evitar la demora diagnóstica y los tratamientos innecesarios(AU)
Monoclonal gammapathies are a broad group of diseases from hematopoietic cells with variable clinical features and systemic or limited involvement. These entities could begin as a rheumatic disease, even previously to the diagnosis of MG. To describe five patients with rheumatic manifestations that lately were diagnosed as monoclonal gammapathies. We describe the more relevant features of five patients assisted in our rheumatology center. Four patients were diagnosed with multiple myeloma that begins as: 1) Schnitzler's syndrome, 2) Adult-onset xanthogranuloma and amyloidosis, 3) multiple vertebral fracture, 4) acute kidney failure. The 5th patient has a vasculitis-like syndrome due to an intravascular lymphoma. The rheumatic-like syndromes are infrequent but we should take into account this diagnosis in our clinical practice for rapid diagnostic and correct treatment(AU)

Presentamos cuatro pacientes con diagnóstico de LES, que durante la evolución de su enfermedad desarrollan cavidades pulmonares.
Cavitary lung lesions in patients with SLE have been described in association with cytomegalovirus pneumonitis, or secondary to fungal infections. Making a review in the literature, 13 cases of patients with these lesions have been described. We present four patients diagnosed with SLE, whom developed lung cavities during the evolution of the disease.

Varón de 47 años que consulta por pérdida de peso, dolor con tumefacción en pantorrillas, fiebre, hipertensión arterial, orquitis y oligoartritis. Laboratorio: anemia y aumento de enzimas musculares. Resonancia magnética: hiperintensidad en gemelos (miositis). Histología de músculo: infiltrado inflamatorio con atrofia y regeneración perifascicular. Tratamiento: pulsos de metilprednisolona y ciclofosfamida. Mialgias, tumefacción muscular y deambulación dificultosa son hallazgos comunes en poliarteritis nodosa (PAN), no así la miositis demostrada histológicamente y más infrecuente aún como forma de inicio de esta vasculitis
A 47-year-old man presented with weight loss, bilateral calf pain, fever, hypertension, orchitis and oligoarthritis. Lab tests: anemia and elevated muscle enzymes. Resonance magnetic imaging: hyperintensity in gastrocnemius muscles (myositis). Histologic exam of the muscles: inflammatory infiltrate with atrophy and perifascicular regeneration. Treatment: methylprednisone (bolus) and cyclophosphamide. Muscle pain and swelling and difficulty in walking are common in panarteritis nodosa (PAN), whereas histologically demonstrated myositis is not. Even more rare is myositis as the initial presentation of this vasculitis

Nailfold videocapillaroscopy (VCP) allows non-invasive assessment of the microcirculation. Adequate training in this field is relevant for rheumatologists. There is increasing evidence of the reliability of VCP findings among different readers. Objective: To evaluate inter- and intra-reader agreement of rheumatologists to identify normal images and systemic sclerosis (SSc) patterns on VCP ("early," "active," and "late" proposed by Cutolo et al.). Thirteen rheumatologists with different experience in nailfold VCP received training to standardize reading criteria. They rated 60 VCP images from healthy and SSc patients at baseline and 4 weeks later, using an electronic platform. The reading of an expert was considered the gold standard. Data were analyzed using Cohen's kappa for concordance and Student's t test and ANOVA to compare kappa means for inter-reader, intra-reader, and inter-pattern readings. Mean inter-reader and intra-reader kappa were 0.45 and 0.49, respectively, (moderate agreement). Kappa scores were higher among experienced vs inexperienced readers (inter-reader kappa 0.58 vs 0.34, p = 0.001, intra-reader kappa 0.65 vs 0.37, p = 0.01). Agreement was substantial (kappa = 0.61) for the identification of normal vs abnormal images and higher for the identification of active (0.48, p = 0.009) and late SSc patterns (0.56, p = 0.008) than for the early SSc pattern (0.35, p = 0.003). There is moderate agreement among rheumatologists for the identification of SSc videocapillaroscopy patterns (higher among experienced rheumatologists) and substantial agreement, regardless of previous experience in VCP, in the identification of normal and abnormal images. Agreement for the identification of active and late patterns is higher than for the early pattern.

La paquimeningitis es un raro desorden caracterizado por engrosamiento focal o difuso de la duramadre, siendo una potencial manifestación de la enfermedad relacionada con IgG4. Presentamos 11 pacientes, seis hombres y cinco mujeres, entre 39-73 años, que consultaron por cefalea, alteraciones visuales, acúfenos, hipoacusia, pérdida de peso, agrandamiento de glándulas salivales, dorsalgia, cuadriplejía y compromiso de nervios craneales. Algunos de ellos presentaron elevación de la proteína C reactiva o del valor de sedimentación globular, mientras que la mayoría presentó niveles séricos normales de IgG4. Todos los pacientes mostraron engrosamiento de la duramadre en la resonancia magnética. La biopsia de duramadre, de vesícula biliar, hipófisis o glándula lagrimal, mostró un infiltrado linfoplasmocitario con o sin fibrosis estoriforme, con más de 10 plasmocitos IgG4 (+) y un rango IgG4: IgG que osciló del 20 al 60 por ciento. Los pacientes recibieron prednisona sola o con rituximab, metotrexate, ciclofosfamida o azatioprina, con respuesta favorable(AU)
Pachymeningitis is a rare disorder characterized by focal or diffuse thickening of the dura mater, being a potential manifestation of the disease related to IgG4. We present 11 patients, six men and five women, aged 39-73 years, who consulted for headache, visual disturbances, tinnitus, hearing loss, weight loss, salivary gland enlargement, dorsalgia, quadriplegia and cranial nerve involvement. Some of them presented elevation of the C-reactive protein or the erythrocyte sedimentation value, while the majority had normal serum levels of IgG4. All patients showed thickening of the dura in magnetic resonance imaging. The biopsy of dura mater, gallbladder, pituitary gland or lacrimal gland showed a lymphoplasmacytic infiltrate with or without storiform fibrosis, with more than 10 IgG4 (+) plasmocytes and an IgG4: IgG range that ranged from 20 to 60 percent. Patients received prednisone alone or with rituximab, methotrexate, cyclophosphamide or azathioprine, with favorable response(AU)
