Características clínicas y evolución de la infección por SARS-CoV-2 en pacientes con lupus eritematoso sistémico en Argentina: datos del registro nacional SAR-COVID / Clinical characteristics and course of SARS-CoV-2 infection in patients with systemic lupus erythematosus in Argentina: data from the SAR-COVID national registry

Introducción: el lupus eritematoso sistémico (LES) es una enfermedad sistémica que se ha asociado a mayor severidad con la infección por SARS-CoV-2. Particularmente la alta actividad de la enfermedad y algunos inmunosupresores se han vinculado a peores desenlaces. Objetivos: describir las características por SARS-CoV-2 en pacientes con LES en Argentina del registro SAR-COVID y establecer los factores asociados a peor desenlace de la misma. Materiales y métodos: estudio observacional. Se incluyeron pacientes con diagnóstico de LES con infección confirmada por SARS-CoV-2 (RT-PCR y/o serología positiva) del registro SAR-COVID. Los datos se recolectaron desde agosto de 2020 hasta marzo de 2022. El desenlace de la infección se midió mediante la escala ordinal de la Organización Mundial de la Salud (EO-OMS). Se definió COVID-19 severo con un valor EO-OMS ≥5. Análisis descriptivo, test T de Student, test de Mann Whitney U, ANOVA, chi2 y Fisher. Regresión logística múltiple. Resultados: se incluyeron 399 pacientes, el 93% de sexo femenino, con una edad media de 40,9 años (DE 12,2). El 39,6% tenía al menos una comorbilidad. Al momento de la infección, el 54,9% recibía glucocorticoides, el 30,8% inmunosupresores y el 3,3% agentes biológicos. La infección por SARS-CoV-2 fue leve en la mayoría de los casos, mientras que un 4,6% tuvo curso severo y/o falleció. Estos últimos presentaban comorbilidades, usaban glucocorticoides y tenían síndrome antifosfolipídico (SAF) con mayor frecuencia y mayor actividad de la enfermedad al momento de la infección. En el análisis multivariado, la hipertensión arterial, el diagnóstico de SAF y el uso de glucocorticoides se asociaron a hospitalización severa y/o muerte por COVID-19 (EO-OMS ≥5). Conclusiones: en esta cohorte de pacientes con LES con infección por SARS-CoV-2 confirmada, la mayoría cursó de manera sintomática, un 22,1% fue hospitalizado y un 5% requirió ventilación mecánica. La mortalidad fue cercana al 3%. El diagnóstico de SAF, tener hipertensión arterial y el uso de glucocorticoides se asociaron significativamente con COVID-19 severo.

Introduction: systemic lupus erythematosus (SLE) is a systemic disease that has been associated with greater severity with SARS-CoV-2 infection. Particularly high disease activity and some immunosuppressants have been linked to worse outcomes. Objectives: to describe the characteristics due to SARS-CoV-2 in patients with SLE in Argentina from the SAR-COVID registry and to establish the factors associated with a worse outcome of the same. Materials and methods: observational study. Patients diagnosed with SLE with confirmed SARS-CoV-2 infection (RT-PCR and/or positive serology) from the SAR-COVID registry were included. Data was collected from August 2020 to March 2022. The outcome of the infection was measured using the World Health Organization - ordinal scale (WHO-OS). Severe COVID-19 was defined as an WHO-OS value ≥5. Descriptive analysis, Student's T test, Mann Whitney U, ANOVA, chi2 and Fisher. Multiple logistic regression. Results: a total of 399 patients were included, 93% female, with a mean age of 40.9 years (SD 12.2), 39.6% had at least one comorbidity. At the time of infection, 54.9% were receiving glucocorticoids, 30.8% immunosuppressants, and 3.3% biological agents. SARS-CoV-2 infection was mild in most cases, while 4.6% had a severe course and/or died. The latter had comorbidities, used glucocorticoids and had antiphospholipid syndrome (APS) more frequently and higher disease activity at the time of infection. In the multivariate analysis, high blood pressure, the diagnosis of APS, and the use of glucocorticoids were associated with severe hospitalization and/or death from COVID-19 (WHO-EO ≥5). Conclusions: in this cohort of SLE patients with confirmed SARS-CoV-2 infection, most had a symptomatic course, 22.1% were hospitalized, and 5% required mechanical ventilation. Mortality was close to 3%. The diagnosis of APS, having high blood pressure, and the use of glucocorticoids were significantly associated with severe COVID-19.

Transcultural adaptation of the EULAR activity index for primary Sjogren's syndrome in Argentine.

OBJECTIVE: To adapt the EULAR Activity Index for primary Sjögren's syndrome (ESSDAI) to the Argentine population. METHODS: observational, cross-sectional study that included patients in a period of ten months. Three Argentine rheumatologists adapted and translated to Spanish the original version in English and the final version was translated back into English by a research associate whose mother language was English. In order to estimate the constructive validity of the index, the visual analogous scale (VAS) of disease activity was used by experts. A subgroup of patients attended a second visit in order to evaluate test-retest reliability. RESULTS: 51 patients were included, 49 (96.1%) were female, the median age was 58 ((interquartile range (IQR): 49-69)). The median global VAS was 10 (IQR: 4-22.25) and the median total ESSDAI score was 5 (IQR: 3-9). The correlation between the global VAS and the total ESSDAI score of the scale was 0.79. The intraclass correlation coefficient was 0.67 (95% CI: 0.32-0.92) for the total score and 0.98 (95% CI: 0.92-0.995) for the global VAS. The results of the correlation coefficient between the VAS and the scale for each domain were: constitutional symptoms: 0.46; lymphadenopathy: 0.76; glandular: 0.78; joint: 0.61; skin: 1; respiratory: 0.83; renal: 1; muscular:- (no patient had myositis); peripheral nervous system: 0.72; central nervous system: 0.67; hematological: 0.96; biomarkers: 0.86. CONCLUSION: The results of this study showed that the ESSDAI is a reliable and valid index for this pSS argentinian population.

Behçet's disease with intestinal perforation: A case report. / Enfermedad de Behçet con perforación intestinal: a propósito de un caso.

A 34-year-old man with an 8-year history of outbreaks of oral and genital ulcers presented with high fever and skin lesions that had developed 21 days earlier, without abdominal pain. Computed tomography revealed intestinal perforation requiring surgery. After treatment with corticosteroids and azathioprine proved to be ineffective, it was switched to adalimumab.

Organ involvement in Argentinian systemic sclerosis patients with "late" pattern as compared to patients with "early/active" pattern by nailfold capillaroscopy.

Changes in nailfold capillaroscopy in systemic sclerosis patients could be related to the disease severity. The aim of this study was to investigate whether patients with "late" scleroderma (SD) pattern have more organ involvement than patients with "early/active" SD pattern. Forty-six Argentinian patients (44 women and 2 men), with a diagnosis of systemic sclerosis, were distributed in two groups based on the presence of late and early/active patterns. Organ involvement was assessed as follows: pulmonary function by chest radiography, high-resolution chest tomography (HRCT), lung volume tests, and diffusing capacity for carbon monoxide (DLCO); esophageal involvement by manometry; and pulmonary arterial hypertension (PAH) by Doppler echocardiography and six-minute walk test. Honeycombing of the lungs evaluated by HRCT was more frequently present in patients with late pattern compared with early/active patients (p = 0.01). We also found statistically significant differences in lung volume tests (p = 0.03) and DLCO (p = 0.02) between the two SD pattern groups. Esophageal manometry showed a significantly higher frequency of motility disorders in the group with late pattern (p = 0.0024). In this study, patients with late pattern had higher frequency of pulmonary and esophageal involvement compared with patients with early/active pattern.

Adherencia al tratamiento de pacientes con artritis reumatoidea que reciben medicamentos biológicos / Treatment adherence in patients with rheumatoid arthritis receiving biologics

Introducción: Al igual que en otras enfermedades crónicas, la adherencia al régimen terapéutico de los pacientes con artritis reumatoidea (AR) es baja (entre 30 y 80%), dependiendo de la definición de adherencia y de la metodología empleada para medirla. En este estudio se propone determinar el nivel de adherencia al tratamiento en pacientes con AR que reciben DMAR biológicas e identificar factores asociados a la falta de cumplimiento a la terapia. Material y métodos: Se realizó un estudio analítico, observacional de corte transversal en donde se incluyeron pacientes consecutivos con AR según criterios de clasificación (ACR’87) que se encontraban recibiendo fármacos biológicos para el tratamiento de su enfermedad en los últimos seis meses y que asistieron a la consulta ambulatoria. Para la valoración de la adherencia a DMAR se utilizaron los cuestionarios CQR (Compliance Questionnaire on Rheumatology) y el cuestionario SMAQ (Simplified Medication Adherence Questionnaire). Resultados: Se encuestaron 345 pacientes. Mediante el cuestionario SMAQ se observó una adherencia del 50% (159 pacientes). El Cuestionario CQR tuvo un puntaje mediano de 78 puntos (RIC 67-86). El 47% (147 pacientes) fueron adherentes (CQR >80). Sobre los pacientes incluidos, 151 (48%) refirieron no haber tenido ningún retraso, pérdida o adelanto de la dosis del biológico en los últimos 6 meses de tratamiento. El 52% no adherentes tuvo como causas: 146 (46%) pérdida de al menos una dosis del biológico con una mediana de dosis perdidas de 2 (RIQ: 1-3); 117 (37%) tuvo al menos un retraso en las dosis del biológico y 8 (2%) delantó la dosis. Los factores asociados al no cumplimiento de la terapia biológica fueron el tipo de cobertura médica, que el paciente no haya notado mejoría y la esperanza de una rápida respuesta al tratamiento, y la falta de adherencia a DMAR

Introduction: As in other chronic diseases, adherence to the therapeutic regimen of patients with rheumatoid arthritis (RA) is low (between 30 and 80%), depending on the definition of adherence and the methodology used to measure it. This study aims to determine the level of adherence to treatment in patients with RA who receive biological DMARs and to identify factors associated with non-compliance with therapy. MATERIAL AND METHODS: An observational, cross-sectional, observational study was performed in which consecutive patients with RA according to classification criteria (ACR'87) who were receiving biological drugs for the treatment of their disease in the last six months were included Attended the outpatient appointment. The CQR (Compliance Questionnaire on Rheumatology) and SMAQ (Simplified Medication Adherence Questionnaire) questionnaires were used to assess adherence to DMAR. Results: A total of 345 patients were surveyed. A 50% adherence (159 patients) was observed through the SMAQ questionnaire. The CQR Questionnaire had a median score of 78 points (RIC 67-86). 47% (147 patients) were adherent (CQR> 80). Regarding the patients included, 151 (48%) reported not having had any delay, loss or advancement of the biological dose in the last 6 months of treatment. The 52% of non-adherents had as causes: 146 (46%) loss of at least one dose of the biological with a median of doses lost of 2 (RIQ: 1-3); 117 (37%) had at least one biological dose delay and 8 (2%) delayed the dose. Factors associated with non-compliance with biological therapy were the type of medical coverage, the patient's perceived improvement and the expectation of a rapid response to treatment, and lack of adherence to DMAR.

Frequency of complications and usefulness of the minor salivary gland biopsy.

UNLABELLED: Findings of specific antibodies and histopathology data are essential for the diagnosis of Sjögren syndrome (SS). Although the minor salivary gland biopsy (MSGB) is technically simple, it needs to be performed in a medical institution to avoid complications. OBJECTIVE: To determine the frequency of complications and the usefulness of this technique. MATERIALS AND METHODS: Patients who underwent a minor salivary gland biopsy for a possible diagnosis of SS at Rivadavia Hospital between October 2007 and May 2010 where included. The patients were seen a week and a month after the procedure for follow up. RESULTS: Frequency of acute complications (n=186): 15 patients; 8.1%, 95% CI: 4.7-13.2 (Bleeding 7.5%, syncope 3.2%, hematoma 2.7%. No accidents occurred). Medium term complications (n=164): 16 patients: 9.75%, 95% CI: 5.9-15.6 (pain 7.32%, inflammation 3.66%, sensitivity disorders 3.05%, granuloma 1.22%,). No infections or suture dehiscence occurred. Microscopic results: 154 biopsy reports were received: glandular 90.9%, 95% CI: 85-95 (typical, sialadenitis, grade III and IV infiltration). CONCLUSIONS: MSGB has very low frequency of medium term and acute complications and it has high usefulness.
