Introducción: los pacientes con enfermedades reumáticas tienen una calidad de vida significativamente deteriorada. La pandemia por COVID-19 tuvo un notable impacto sobre la población y los sistemas de salud de todo el mundo. Objetivos: en este trabajo nos proponemos conocer el impacto de la pandemia en la calidad de vida de los pacientes con esclerosis sistémica (ES) y cómo fue el acceso a la atención médica. Materiales y métodos: mediante encuestas anónimas y digitales a pacientes durante julio y agosto de 2020 se evaluó la calidad de vida utilizando el cuestionario de calidad de vida de la esclerosis sistémica (SScQoL). Además, se realizaron preguntas para evaluar el acceso al sistema de salud durante ese período. Resultados: se encuestaron 300 pacientes con ES. La mediana de afectación de la calidad de vida según el cuestionario utilizado fue de 17 (9,25-22) y el dolor fue el dominio más afectado. El 29,33% no hizo los controles médicos. El 74,33% refirió haber tenido estudios médicos pendientes al inicio de la cuarentena y solo el 25% pudo realizarlos. Conclusiones: los pacientes con ES presentaron compromiso de la calidad de vida durante la pandemia y mostraron dificultades en el acceso al sistema de salud.

Introduction: patients with rheumatic diseases have a significantly impaired quality of life. The COVID-19 pandemic has had a significant impact on the population and health systems around the world. Objectives: to analyze the impact of the pandemic on the quality of life and access to medical care of patients with systemic sclerosis (SS). Materials and methods: through anonymous and digital surveys of patients during July and August 2020, quality of life was assessed using the Systemic Sclerosis Quality of Life Questionnaire (SScQoL). In addition, questions were asked to assess access to the health system during that period. Results: 300 patients with SS were surveyed. The median quality of life affectation according to the questionnaire used was 17 (9.25-22), with pain being the most affected domain. Twenty-nine percent did not attend their medical appointments, 74.33% reported having pending medical studies at the beginning of the quarantine, and only 25% could carry them out. Conclusions: patients with SS presented compromised quality of life during the pandemic and showed difficulties in accessing the health system.

Taller de concordancia en la evaluación de imágenes capilaroscópicas / Reliability of nailfold videocapillaroscopy workshop

Introducción: la capilaroscopia es un método no invasivo que permite observar la microvasculatura en el área periungueal. Los resultados informados pueden ser altamente variables entre distintos observadores. A lo largo del tiempo surgieron métodos cuantitativos y semicuantitativos para mejorar la reproducibilidad. Objetivos: conocer el nivel de acuerdo intra e interobservador al informar los diferentes patrones capilaroscópicos en individuos con diferente nivel de entrenamiento. Materiales y métodos: estudio de corte transversal. Participaron médicos reumatólogos especialistas y en formación que habían realizado previamente un curso virtual de capacitación en capilaroscopia. Recibieron 40 imágenes capilaroscópicas proyectadas en una presentación de PowerPoint y debían responder a través de un cuestionario digital. Se evaluó la concordancia de respuestas intra e interobservador. Resultados: se encontró un alto nivel de concordancia global con un kappa 0,66 IC 95% (0,63-0,70) p<0,0000. También en otros grupos como reumatólogos en formación: kappa 0,65 IC 95% (0,60-0,71) p=0,0000, y médicos reumatólogos: kappa 0,67 IC 95% (0,62-0,72) p=0,0000. Conclusiones: el nivel de concordancia encontrado fue globalmente alto, independientemente del nivel de entrenamiento de los profesionales, y de ser o no reumatólogo. La concordancia fue superior cuando se comparó a quienes tenían más de 4 años de experiencia en la realización de videocapilaroscopia.

Introduction: videoapillaroscopy is a non-invasive method that allows the observation of the microvasculature in the periungual area. Reported results can be highly variable between different observers. Over time, quantitative and semi-quantitative methods emerged to improve reproducibility. Objetives: to know the level of intra and interobserver agreement when reporting the different capillaroscopic patterns in individuals with different levels of training. Materials and methods: cross section study. Specialist rheumatologists and those in training who had previously completed a virtual capillaroscopy training course participated. They received 40 capillaroscopic images projected in a PowerPoint presentation and had to issue their response through a digital questionnaire. Concordance of intra and interobserver responses was evaluated. Results: a high level of global agreement was found with a kappa 0.66 CI 95% (0.63-0.70) p<0.0000, also in other groups such as rheumatologists in training: kappa 0.65 CI 95% (0.60-0.71) p=0.0000, physicians rheumatologists: kappa 0.67 95% CI (0.62-0.72) p=0.0000. Conclusions: the level of agreement found was globally high, regardless of the level of training of the professionals, and whether or not they were a rheumatologist. Concordance was higher when compared to those who had more than 4 years of experience performing videocapillaroscopy.

Rheumatoid Arthritis Patient's Journey: Delay in Diagnosis and Treatment.

OBJECTIVES: The aims of this study were to establish delay times from articular symptoms onset to first rheumatologist consultation, rheumatoid arthritis (RA) diagnosis, and treatment initiation with disease-modifying antirheumatic drug (DMARD) therapy and to assess the impact of delayed diagnosis on structural damage. METHODS: This was an observational cohort study. Rheumatoid arthritis adult patients treated in a private health system between January 1, 1996, and December 31, 2016, were included. Electronic medical records were reviewed to obtain clinical and demographic data, dates of first disease symptom, diagnosis, and date of first treatment with DMARDs. Physical function (Health Assessment Questionnaire) and structural damage (Sharp score modified by van der Heijde) were also assessed. RESULTS: Two hundred forty-six patients (81% female), with a mean age of 67.25 (standard deviation [SD], 14.53) years, were included. At the end of follow-up period, median Health Assessment Questionnaire (n = 145) and radiological scores (n = 171) were 0.125 (interquartile range, 0-0.87) and 15 (interquartile range, 6-33), respectively. A mean of 9.2 (SD, 20) months (median, 3 months) elapsed from the first disease symptom to rheumatologist consultation, 14.2 (SD, 24) months (median, 4.8 months) to RA diagnosis, and 16.9 (SD, 25.4) months (median, 7 months) to treatment initiation with DMARDs. Significantly greater structural damage was found in patients with a diagnosis delay of more than 12 months (n = 70) (p = 0.0325). CONCLUSIONS: Despite good access to medical consultation in a private health system, there is still a delay to RA diagnosis and to start pharmacological therapy. A delay of more than 12 months was significantly associated with greater radiological damage after 5 years of follow-up.

Evaluation of Learned Helplessness, Perceived Self-efficacy, and Functional Capacity in Patients With Fibromyalgia and Rheumatoid Arthritis.

OBJECTIVES: The aims of this study were to compare learned helplessness (LH) and perceived self-efficacy (SE) in patients with fibromyalgia (FM) and rheumatoid arthritis (RA) and to assess their correlation with functional disability, level of perceived pain, and fatigue. METHODS: This multicenter, cross-sectional study included consecutive patients (aged ≥18 years) with RA, according to the 2010 American College of Rheumatology/European League Against Rheumatism criteria, and FM, according to 2010 American College of Rheumatology criteria. Learned helplessness was measured by the Rheumatology Attitude Index, Spanish version; SE with the Arthritis Self-efficacy Scale, Spanish version; functional capacity with the Health Assessment Questionnaire (HAQ), Argentine version; depression with Center for Epidemiological Studies-Depression Scale 7-item version and perceived pain and fatigue by the visual analog scale. Disease activity was measured by the Clinical Disease Activity Index (CDAI) and disease impact with the Fibromyalgia Impact Questionnaire (FIQ). RESULTS: A total of 215 patients, 100 with FM and 115 with RA, were included. Mean age was 59 (SD, 14) years and 58 (SD, 13) years for FM and RA, patients respectively. Whereas LH and depression were significantly higher, SE was significantly lower in FM patients. We found a positive correlation between LH and HAQ, pain, depression, fatigue, FIQ, and CDAI in FM and RA patients. We observed a negative correlation between SE and HAQ, pain, depression, fatigue, FIQ (FM), and CDAI (RA) in both groups. CONCLUSIONS: Both LH and SE correlate significantly with functional capacity, perceived pain, disease activity, and disease impact in RA and FM patients. Learned helplessness was higher in patients with active disease or high disease impact, as opposed to those in remission or with low disease impact, and the reverse was true for SE. Patients with FM had significantly more LH, pain, fatigue, and depression and less SE compared with those with RA.

Can nailfold videocapillaroscopy images be interpreted reliably by different observers? Results of an inter-reader and intra-reader exercise among rheumatologists with different experience in this field.

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.

Are There Clinical Differences in Limited Systemic Sclerosis according to Extension of Skin Involvement?

Objectives. To examine the characteristics of our patients with limited systemic sclerosis (lSSc) for differences between Barnett Type 1 (sclerodactyly only) and Type 2 or intermediate (acrosclerosis-distal but may reach up to elbows and/or knees plus face) subsets. Methods. Records of patients between January 1, 2000, and December 31, 2011, with SSc or those with anti-Scl-70, anticentromere, or antinucleolar antibodies were reviewed. Only cases fulfilling ACR 1980 criteria were included and classified as diffuse or limited according to LeRoy's criteria. Limited SSc was separated into sclerodactyly and acrosclerosis (Barnett's Types 1 and 2). Results. 234 SSc patients (216 females) fulfilled criteria. Female/male ratio was 12 : 1; 24% had dSSc and 76% lSSC (64% Type 1 and 12% Type 2). Total follow-up was 688 patient-years. Within lSSC, the Type 2 group had significantly shorter duration of Raynaud's and more anti-Scl-70 and less anticentromere antibodies. In particular, interstitial lung disease (ILD) was significantly more prevalent in Type 2 group and similar to Type 3. Conclusions. These results appear to confirm that extension of skin involvement within limited SSc may identify two different subsets with clinical and serologic characteristics.

Incidence and prevalence of polymyositis and dermatomyositis in a health management organization in Buenos Aires.

BACKGROUND: Polymyositis (PM) and dermatomyositis (DM) are infrequent diseases. Data on incidence and prevalence are scarce and conflicting. There are no such data in Latin America and in Argentina in particular. OBJECTIVES: We undertook to examine the incidence and prevalence of PM/DM in the prepaid health maintenance organization (HMO) of our hospital, in the city of Buenos Aires. METHODS: Members of the HMO between January 1999 and June 2009 were identified from medical records of patients followed up by us at the HMO. Incident cases and prevalence were calculated at the end of the period. RESULTS: During the study period, 146,747 persons contributed a total of 937,902.6 person-years (mean age was 46.6 [SD, 18.4] years, and 59% were female). Ten incident cases were detected, 7 women and 3 men with a global incidence rate (IR) of 1.07 per 100,000 person-years (95% confidence interval [CI], 0.5-1.84). Three subjects had DM with an IR of 0.32 per 100,000 person-years (95% CI, 0.1-0.99), and 7 had PM with an IR of 0.75 per 100,000 person-years (95% CI, 0.35-0.16). On June 1, 2009, 17 prevalent cases were detected, with a mean age of 48.9 (SD, 17.7) years; 76% were female, representing a prevalence of 17.4 per 100,000 persons (95% CI, 10.1-27.8). Among the 17 patients with idiopathic inflammatory myopathy, 10 patients had DM, with a prevalence of 10.22 per 100,000 persons (95% CI, 4.9-18.8), and 7 had PM (prevalence, 7.2 per 100,000 persons [95% CI, 2.9-14.7]). CONCLUSIONS: It is difficult to compare studies from different populations and using different ascertainment techniques. These first data from Latin America are in general agreement with many studies.

Validation in Spanish of a screening questionnaire for the detection of psoriatic arthritis in patients with psoriasis.

OBJECTIVE: A patient self-administered questionnaire [PsA Screening and Evaluation (PASE)] has been developed and validated in English, but has not been tried in Spanish speaking populations. This study aimed to adapt and validate PASE in Spanish to screen Spanish speaking psoriasis patients for signs and symptoms of inflammatory arthritis. METHODS: Initial translation from English to Spanish (forward translation) was performed by two independent translators and the resulting versions were synthesized during a consensus meeting. The questionnaire was tried in a pilot study and resulted in a change in the agreement scale for a frequency scale with wording adaptation [Spanish PASE (PASE-S)]. RESULTS: One hundred and eleven patients were screened with PASE-S; 25 with PsA (without previous treatments), 23 with psoriasis, 22 with psoriasis and OA and 41 with OA without psoriasis. The diagnosis of psoriasis was performed by a dermatologist, and a rheumatologist determined the diagnosis of PsA or OA. Patients with PsA had statistically significant higher symptoms, function and total PASE-S scores compared with those without PsA. Receiver operator curves showed an area under the curve of 0.79 (95% CI 0.69, 0.89) for the total score. A cut-off value ≥34 showed sensitivity of 76%, and specificity of 74.4% for the diagnosis of PsA. CONCLUSION: The validated PASE questionnaire is a self-administered tool that can be used to screen for PsA among patients with psoriasis in a Spanish speaking population. PASE was able to distinguish between symptoms of PsA and OA.
