RESUMEN

Objetivo: Determinar la frecuencia de complicaciones materno-perinatales y factores clínicos asociados a estos resultados en estantes con lupus. Métodos: Se realizó un estudio de casos y controles a partir de historias clínicas de pacientes con diagnóstico Lupus Eritematoso Sistémico en embarazo, entre 2010-2022 en una institución de salud en Medellín-Colombia. Éstas se clasificaron como casos (pacientes con resultados adversos materno-perinatales) y controles (pacientes sin resultados adversos). Resultados: Se incluyó un total de 67 pacientes (35 casos y 32 controles). Las complicaciones maternas más frecuentes fueron los trastornos hipertensivos asociados al embarazo (71,4 %), incluyendo preeclampsia y una presentación importante de partos pretérmino (68,6 %). La nefritis lúpica previa y durante el embarazo, fue más frecuente en los casos que en los controles (31,4 % versus 9,4 %). Los compromisos cardiovasculares, de mucosas y musculo-esquelético, fueron más frecuentes durante el embarazo (31,4 %, 40 % y 34,3 %, respectivamente), coincidiendo con mayor actividad del lupus, principalmente durante el embarazo. El compromiso cardiovascular y de mucosas durante el embarazo, así como tener síndrome antifosfolípido se relacionaron con desenlace materno-perinatal adverso. Conclusión: Componentes clínicos propios de la enfermedad como la nefritis lúpica, el síndrome antifosfolípido, el compromiso cardiovascular, y de mucosas podrían predisponer a desenlaces maternos y/o perinatales adversos como trastornos hipertensivos asociados al embarazo, pretérmino, restricción de crecimiento fetal, entre otros(AU)

Objective: To determine the frequency of maternal-perinatal complications and the clinical factors associated with these outcomes in pregnant women with lupus. Methods: A case-control study was conducted using the medical records of patients diagnosed with pregnancy and lupus in a healthcare institution in Medellin, Colombia, between 2010 and 2022. The patients were classified as cases (patients with adverse maternal-perinatal outcomes) and controls (patients without adverse outcomes). Results: A total of 67 patients (35 cases and 32 controls) were included. The most frequent maternal complications were pregnancyassociated hypertensive disorders (71.4%), including preeclampsia and a significant presentation of preterm deliveries (68.6%). Lupus nephritis prior to and during pregnancy was more frequent in cases than in controls (31.4% versus 9.4%). Cardiovascular, mucosal and musculoskeletal compromises were more frequent during pregnancy (31.4%, 40% and 34.3%, respectively), coinciding with greater lupus activity, mainly during pregnancy. Cardiovascular and mucosal involvement during pregnancy, as well as having antiphospholipid syndrome, were related to adverse maternal-perinatal outcome. Conclusion: Clinical components of the disease such as lupus nephritis, antiphospholipid syndrome, cardiovascular and mucosal involvement, are factors that may predispose these patients to adverse maternal and/or perinatal outcomes, such as hypertensive disorders associated with pregnancy, low birth weight, preterm, fetal growth restriction, among others(AU)

RESUMEN

AIM: To describe the impact of the COVID-19 on the psychosocial health of patients with rheumatoid arthritis (RA), spondyloarthritis (SpA), and systemic lupus erythematosus (SLE). DESIGN: Longitudinal observational study of a series of patients with rheumatic disease. METHODS: The main outcome measure was impairment of the ability to participate in social activities, as measured using the PROMIS-APS instrument Short Form-8a. We evaluated social activities in various settings and performed a multivariate analysis to study the association between worsening of social participation during the COVID-19 pandemic and implicated factors. RESULTS: One hundred and twenty-five patients had completed the prospective follow-up: 40 with AR (32%), 42 with SpA (33.6%), and 43 with SLE (34.4%). Overall, poorer mean PROMIS scores were recorded after the COVID-19 pandemic for: satisfaction with social roles (p=0.029), depression (p=0.039), and ability to participate in social activities (p=0.024). The factors associated with ability to participate in social activities after the COVID-19 pandemic were older age (ß=-0.215; p=0.012), diagnosis of SLE (ß=-0.203; p=0.015), depression (ß=-0.295; p=0.003) and satisfaction with social roles (ß=0.211; p=0.037). CONCLUSION: The ability to participate in social activities after the COVID-19 pandemic is affected in patients with rheumatic disease, especially in SLE.

RESUMEN

BACKGROUND: Hydroxychloroquine (HCQ) is the first-line treatment for systemic lupus erythematosus (SLE); however, there is heterogeneity in its clinical use. This consensus aims to bridge the gap in SLE treatment by providing practical and valuable recommendations for health professionals. METHODS: The methodology used is based on a systematic literature review and a nominal group technique (NGT). A ten-member scientific committee formulated eight clinically relevant questions. First, a systematic review was conducted to identify the available evidence, which the scientific committee evaluated to developed recommendations based on their expertise, achieving consensus through NGT. RESULTS: 1673 titles and abstracts were screened, and 43 studies were included for meeting the inclusion criteria. The scientific committee established 11 recommendations for HCQ use in initiation, maintenance, and monitoring, considering benefits and potential adverse effects of HCQ. Unanimous agreement was achieved on all recommendations. CONCLUSIONS: The available evidence supports HCQ's effectiveness and safety for SLE. Individualized assessment of the initial HCQ dose is important, especially in situations requiring dose reduction or discontinuation. This risk-benefit assessment, specifically focusing on the balance between retinal toxicity and the risk of SLE relapse, should guide decisions regarding medication withdrawal, considering disease activity, risk factors, and HCQ potential benefits. Close monitoring is essential for optimal disease management and minimize potential risks, such as QT prolongation or retinal toxicity.

RESUMEN

Introducción: El lupus eritematoso sistémico (LES) es una enfermedad autoinmune que causa inflamación sistémica y alteraciones en la tolerancia inmunológica. La activación de los genes inducibles por interferón (IFN), contribuye en más del 50% de su patogenia. Objetivo: relacionar el papel del IFN-λ en la patogenia del LES. Materiales y Métodos: Búsqueda sistémica en base de datos; a través de las palabras claves del MeSH and DeCS. Fue incluido adicionalmente la palabra "Interferón Lambda". Resultados: Se encontró que la producción aberrante de interferón tipo I contribuye a la desregulación de IFN-λ, producido principalmente por células dendríticas plasmocitoides. Este proceso conduce a la estimulación inmunológica por autoanticuerpos y a un aumento de IFNλR-1 en células B, potenciando la generación de anticuerpos. IFN-λ3 se asocia particularmente con nefritis lúpica, y el IFN-λ en general aumenta la expresión de MHC-I, intensificando la respuesta de células T CD8+ y posiblemente afectando la tolerancia central y la regulación en el timo. Conclusión: Se destaca que el IFN-λ favorece la activación inmune, formación de inmunocomplejos, inflamación crónica y producción de autoanticuerpos, vinculándose niveles altos de IFN-λ3 con mayor actividad de la enfermedad.

Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease that causes systemic inflammation and alterations in immunological tolerance. The activation of interferon (IFN)-inducible genes contributes to more than 50% of its pathogenesis. Objective: to review the role of IFN-λ in the pathogenesis of SLE. Materials and Methods: Systemic search in database; through the MeSH and DeCS keywords. The word "Lambda Interferon" was additionally included. Results: Aberrant production of type I interferon was found to contribute to the deregulation of IFN-λ, produced mainly by plasmacytoid dendritic cells. This process leads to immunological stimulation by autoantibodies and an increase in IFNλR-1 in B cells, enhancing the generation of antibodies. IFN-λ3 is particularly associated with lupus nephritis, and IFN-λ generally increases MHC-I expression, enhancing the CD8+ T cell response and possibly affecting central tolerance and regulation in the thymus. Conclusion: It is highlighted that IFN-λ favors immune activation, formation of immune complexes, chronic inflammation and production of autoantibodies, linking high levels of IFN-λ3 with greater disease activity.

RESUMEN

BACKGROUND: Patients with systemic lupus erythematosus (SLE) have an increased risk of metabolic syndrome (MS) and cardiovascular (CV) disease. MS is evaluated binary, limiting the understanding of each component's severity individually. Therefore, severity scores for MS that evaluate them separately have been developed. This study aims to determine the prognosis between MS severity and the occurrence of major adverse cardiovascular events (MACE) in SLE patients. METHODS: Ten-year follow-up cohort study. Premenopausal>18-year-old women with a previous diagnosis of SLE were included. Patients with recent CV events, pregnancy, thyroid disease, and liposuction were excluded. The variables of interest were CV events; the confounding variables, and the MS severity indexes were examined. Hazard ratios and Kaplan-Meier survival curves were estimated through Cox regression. RESULTS: A total of 238 women were analyzed: 22 presented MACE, and 216 did not. MS prevalence, measured according to consensus and ATP-III criteria, was higher in MACE patients (50 and 40,95%, respectively). The MetSx-IMC severity index was higher within the MACE group. Cox analysis showed an increase in the MetSx-IMC associated with the risk of suffering MACE in a 1.107 ratio. CONCLUSIONS: The MetSx-IMC severity index, contrary to the binary approaches, is recommended to evaluate MS as a predictor of MACE in SLE patients. Offering improved and more accurate prognosis in patients at risk of developing MCE.

La enfermedad mixta del tejido conectivo es enfermedad autoinmunitaria sistémica con la asociación de manifestaciones clínicas de otras entidades autoinmunes. Objetivo:Describir la presentación de dos enfermedades sistémicas autoinmunes poco frecuentes en conjunto, con el propósito de contribuir con un enfoque prác-tico para el diagnóstico y manejo. Presentación del caso: Se describe una paciente de 37 años que presentó un episodio de tromboembolia pulmonar secundario a síndrome de anticuerpos anti-fosfolípidos y en los 6 meses previos tuvo síntomas compatibles con enfermedad mixta del tejido conectivo. Discusión: La presencia de dos entidades autoinmunes, síndrome de anticuerpos antifosfolípidos y enfermedad mixta del tejido conectivo presentadas en conjunto y cuyo debut de complicaciones fue una tromboembolia pulmonar, encontrándo-se presencia de múltiples autoanticuerpos positivos entre estas anticuerpos an-tifosfolipídicos y anti-U1 snRNP, es un reto diagnóstico al diferenciar entre otras enfermedades del tejido conectivo como lupus eritematoso sistémico, esclerosis sistémica cutánea, enfermedad mixta del tejido conectivo y artritis reumatoide. El tratamiento se basó en las características del paciente y su condición clínica al momento del diagnóstico. Conclusiones: El síndrome de anticuerpos antifosfolipídicos conlleva la presencia de un episodio trombótico, por otro lado, su asociación con una enfermedad mixta del tejido conectivo es poco frecuente y puede aumentar su morbimortalidad.

Introduction: Antiphospholipid antibody syndrome is a rare systemic autoimmu-ne disease that produces Antiphospholipid antibody syndrome is a rare systemic autoimmune disease that causes hypercoagulability with risk of thrombosis. For diagnosis, the ACR/EULAR APS 2023 criteria are used. Treatment is anticoagulants and antiplatelet agents.Mixed connective tissue disease is a systemic autoimmune disease with the asso-ciation of clinical manifestations of other autoimmune entities.Objective:To describe the presentation of two rare autoimmune systemic diseases toge-ther, with the purpose of contributing a practical approach to diagnosis and management.Case presentation: 37-year-old patient with an episode of pulmonary thromboem-bolism secondary to antiphospholipid antibody syndrome and in the previous 6 months he had symptoms compatible with mixed connective tissue disease.Discussion:The presence of two autoimmune entities, antiphospholipid antibody syndrome and mixed connective tissue disease presented together and whose de-but of complications was a pulmonary thromboembolism, finding the presence of multiple positive autoantibodies between these antiphospholipid antibodies and an-ti-U1 snRNP, is a diagnostic challenge in differentiating between other connective tissue diseases such as systemic lupus erythematosus, cutaneous systemic sclero-sis, mixed connective tissue disease and rheumatoid arthritis. Treatment was based on the patient's characteristics and clinical condition at the time of diagnosis.Conclusions: Antiphospholipid antibody syndrome entails the presence of a thrombotic episode; on the other hand, its association with a mixed connective tissue disease is rare and may increase its morbidity and mortality.

RESUMEN

BACKGROUND: Females diagnosed with systemic lupus erythematosus (SLE) face an elevated risk of adverse pregnancy outcomes (APOs). However, the evidence regarding whether a similar association exists in patients with undifferentiated connective tissue disease (UCTD) is inconclusive. METHODS: We conducted a retrospective review (2006-2019) of pregnancy outcomes among patients with SLE (n = 51) and UCTD (n = 20) within our institution. We examined the occurrence of various APOs, encompassing miscarriage, stillbirth, termination, preterm birth, pre-eclampsia, eclampsia, HELLP syndrome, intrauterine growth restriction, abruption placentae, congenital heart block, or other cardiac abnormalities. RESULTS: The mean age at pregnancy was 35 ±â€¯7.0 years for patients with SLE and 35 ±â€¯6.8 years for those with UCTD (p = 0.349). The proportion of Caucasian women was 47% in SLE and 80% in UCTD. Pregnancies in both groups were planned (81% in SLE and 77% in UCTD), and patients presented with inactive disease at conception (96% in SLE and 89% in UCTD). Hydroxychloroquine at conception was utilized by 86% of women with SLE, in contrast to 36% in the UCTD group. Both, SLE and UCTD cohorts exhibited low rates of disease flares during pregnancy and/or puerperium (14% vs. 10%). The incidence of APOs was 15.6% in SLE patients compared to 5% in those with UCTD (Risk difference 19.5%; 95% confidence interval: -3.9 to 43.1; p = 0.4237). CONCLUSION: Our study underscores the importance of strategic pregnancy planning and the maintenance of appropriate treatment throughout pregnancy to ensure optimal disease management and minimize adverse outcomes in both SLE and UCTD pregnancies.

RESUMEN

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by the production of autoantibodies directed against endogenous antigens causing various clinical manifestations, chronic inflammation and tissue damage. Although the pathophysiology of SLE remains unknown, it is recognized that genetic, epigenetic, environmental and neuroendocrine factors are involved in the development of the disease and its complications. A notable proportion of patients with SLE also present obesity, and this dysmetabolic profile can cause renal, musculoskeletal and/or respiratory deterioration, fatigue, various pathophysiological alterations and functional deterioration. In this context, precision nutrition emerges as a promising tool in the inflammatory control of SLE, especially in patients with associated obesity. Various studies demonstrate the beneficial influence of balanced dietary patterns in macronutrients with foods rich in fiber, vitamins, minerals, antioxidants and polyphenols on the inflammatory control of SLE and the most diverse pathologies, highlighting the Mediterranean diet and plant-based diets. Finally, the intestinal microbiota may play a relevant role in this clinical scenario, since dysbiosis is associated with inflammatory processes and immune deregulation. It is believed that precision nutrition can modulate inflammatory profiles and immune dysfunctions to ensure better quality of life and metabolic well-being of SLE patients with the support of precision omics technologies.

El lupus eritematoso sistémico (LES) es una enfermedad autoinmune caracterizada por la producción de autoanticuerpos dirigidos contra antígenos endógenos causando diversas manifestaciones clínicas, inflamación crónica y daño tisular. Aunque la fisiopatología del LES sigue siendo desconocida, se reconoce que factores genéticos, epigenéticos, ambientales y neuroendocrinos están implicados en el desarrollo de la enfermedad y sus complicaciones. Una proporción notable de pacientes con LES presenta también obesidad, y este perfil dismetabólico puede producir deterioro renal, musculoesquelético y/o respiratorio, fatiga, diversas alteraciones fisiopatológicas y deterioro funcional. En este contexto, la nutrición de precisión emerge como una herramienta prometedora en el control inflamatorio del LES, especialmente en pacientes con obesidad asociada. Diversos estudios demuestran la influencia beneficiosa de patrones dietéticos equilibrados en macronutrientes con alimentos ricos en fibra, vitaminas, minerales, antioxidantes y polifenoles en el control inflamatorio del LES y de las más diversas patologías, destacando la dieta Mediterránea y las dietas basadas en plantas/vegetales. Por último, la microbiota intestinal puede tener un papel relevante en este escenario clínico, ya que la disbiosis se asocia con procesos inflamatorios y desregulación inmune. Se cree que con la nutrición de precisión se pueden modular los perfiles inflamatorios y las disfunciones inmunitarias para garantizar una mejor calidad de vida y el bienestar metabólico de los pacientes con LES con el apoyo de las tecnologías de precisión ómicas.

RESUMEN

BACKGROUND: Neonatal lupus (NL) is extremely rare and is caused by the transplacental passage of maternal IgG autoantibodies against Ro, La, and/or RNP proteins into the fetal circulation, which can cause congenital complete atrioventricular block (CCAB), permanent skin lesions, and liver involvement. OBJECTIVE: To know the prevalence of NL in patients with CCAB and the clinical course in long-term follow-up. METHODS: From January 1992 to December 2017, patients with CCAB were included. The presence of anti-SSA/Ro and anti-SSB/La antinuclear antibodies in maternal serum confirmed NL. RESULTS: Eight patients were included with a follow-up of 10 ± 6 years; NL was concluded in 62.5%; two were male. One of them was diagnosed in utero, two at birth, and a pacemaker was implanted in them, one at 12 years of age and another at 15. The other two cases were diagnosed at 18 and 26 years of age, and permanent pacemakers were implanted 8 and 5 years later, respectively. In one case, a definitive pacemaker was not implanted in a newborn with only 1 year of follow-up. At delivery, 60% of the mothers were free of rheumatic disease, and altogether, they all had 19 children; none of them presented NL manifestations. CONCLUSIONS: CCAB is rare and frequently associated with a maternal autoimmune disease, practically all of them will require a definitive pacemaker at some point in their lives.

ANTECEDENTES: El lupus neonatal (LN) es extremadamente raro y es ocasionado por el paso transplacentario de auto-anticuerpos maternos IgG contra las proteínas Ro, La y/o RNP a la circulación fetal que puede ocasionar bloqueo aurículo-ventricular completo congénito (BAVCC) permanente, lesiones dérmicas y afectación hepática. OBJETIVO: Conocer la prevalencia de LN en paciente con BAVCC y la evolución clínica en un seguimiento a largo plazo. MÉTODOS: De enero de 1992 a diciembre 2017 se incluyeron paciente con BAVCC. La presencia de anticuerpos antinucleares anti-SSA/Ro y anti-SSB/La en suero materno confirmó LN. RESULTADOS: Ocho pacientes fueron incluidos con seguimiento de 10 ± 6 años, el 62.5 % con LN; dos fueron del sexo masculino. Uno diagnosticado in útero, dos al nacimiento, en ellos se implantó marcapaso; uno a los 12 años de edad y otro a los 15. Los otros dos casos fueron diagnosticados a los 18 y 26 años, se implantó marcapaso definitivo en ellos 8 y 5 años después respectivamente. En un caso no se implantó marcapaso definitivo; un recién nacido con solo un año de seguimiento. Al dar a luz, el 60 % de las madres estaban libres de enfermedad reumática y en conjunto todas tuvieron 19 hijos, ninguno de ellos presentó manifestaciones de LN. CONCLUSIONES: El BAVCC es raro y frecuentemente está asociado a una enfermedad autoinmune materna, prácticamente todos requerirán de marcapaso definitivo en alguna época de su vida.

RESUMEN

Objetivos: estudiar los efectos secundarios y el riesgo de exacerbación de la en-fermedad después de la vacunación COVID-19 en una muestra de pacientes con lupus eritematoso sistémico (LES). Materiales y métodos: estudio retrospectivo que investigó 101 pacientes con LES. Se determinó la actividad de la enfermedad mediante el Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) antes y después de dos dosis de la vacuna contra el SARS-COv-2. Se registraron los efectos secundarios después de la vacunación. Resultados: los pacientes que recibieron dos dosis de la misma vacuna fue-ron el 10,3% para CoronaVAc, el 42,2% para Pfizer y el 47,3% para AstraZeneca. Se detectaron efectos secundarios en el 76,2% y la mayoría fue leve/moderado. Los más frecuentes fueron: dolor local (62,3%), cefalea (36,6%) y fatiga (34,6%). El cambio en la mediana del SLEDAI antes de la primera dosis y después de la segunda no fue estadísticamente significativo (p=0,68). Solo el 4,1% de los individuos aumentó el SLEDAI ≥ de 3 puntos. Conclusiones: la vacunación contra la COVID-19 fue bien tolerada y segura en pacientes con LES.

Objectives: to study the side effects and the risk of disease flare after COVID-19 vaccination in Brazilian patients with Systemic Lupus erythematosus (SLE). Materials and methods: this retrospective study investigated a sample of 101 SLE patients for disease activity through the SLE disease activity index (SLEDAI) prior to and after two vaccine doses against SARS-COv-2. Side effects after vaccination were recorded. Results: in this sample, patients receiving two doses of the same vaccine were 10.3% for CoronaVAc; 42.2% for Pfizer, and 47.3% for AstraZeneca. Side effects were detected in 76.2% of them, and most of them were mild and moderate; the most common were local pain (62.3%), headache (36.6%), and fatigue (34.6%). The SLEDAI prior to the first dose and after the second dose did not change significantly (p=0.68). Only 4.1% of individuals had increased in SLEDAI ≥than 3 points. Conclusions: vaccination against COVID-19 was well tolerated and safe in SLE patients

RESUMEN

INTRODUCTION: Immune thrombocytopenia (ITP) is a potentially severe manifestation of systemic lupus erythematosus (SLE) reported in 7-40% of SLE patients. ITP has been associated with a higher risk of organ damage and mortality. OBJECTIVES: To describe which factors are associated with the presence of ITP in SLE patients. METHODS: Retrospective case-control study. Cases were defined as SLE patients who had ever developed ITP and were sex- and age-matched with two controls. A predictive model was constructed to identify SLE patients who were at risk of developing ITP. RESULTS: ITP prevalence in our SLE cohort was 8.35%. Cases had a higher frequency of hemolytic anemia, while controls had a higher prevalence of arthritis at SLE diagnosis. During SLE progression, cases tested positive for anticardiolipin, anti-ß2-glycoprotein 1, and lupus anticoagulant antibodies more frequently. Cases received mycophenolic acid and azathioprine more often than controls and had a higher SLICC/ACR score. The model demonstrated a sensitivity of 87.53%, a positive predictive value of 81.92%, a specificity of 80.50%, area under the curve of 83.92%, a F1 of 83% and an overall accuracy of 83.68%. The variables that best explain the model were hemolytic anemia, arthritis, oral ulcers, Raynaud's phenomenon, low C4, low CH50, anticardiolipin and anti-ß2GP1 antibodies. CONCLUSION: SLE patients who develop ITP have a distinct phenotype characterized by more hemolytic anemia and less arthritis at SLE onset, and higher prevalence of antiphospholipid syndrome antibodies during SLE progression. This phenotype is associated with heightened organ damage and the need for more intensive therapies and stricter follow-up. Our predictive model has demonstrated an impressive ability to identify SLE patients at risk of developing ITP.

In international series, presentation of infectious processes is described in these patients in up to 75 % of cases. Infections occur both at the beginning of the disease and in late stages, and are a direct cause of death in 30 % to 60 % of patients. Cases and reason for hospitalization up to 30 %. Objectives: determine the most frequent infectious processes in patients with systemic lupus erythematosus admitted to the Medical Clinic Service of the Hospital Nacional in the period 2022-2023. Methodology: observational, descriptive cross-sectional design of patients with a diagnosis of systemic lupus erythematosus according to criteria of European League Against Rheumatism (EULAR)-2019 who are admitted to the Medical Clinic service of the Hospital Nacional (Itauguá-Paraguay) in the period of 2022-2023. Results: the average age of the patients was 34 years, with a predominance of the female sex in 88.18 %. Respiratory system infections were the most frequently diagnosed in 50 (45.45 %) patients, followed by urinary tract infection in 47 (42.38 %) patients. The predominant risk factor was the use of corticosteroids in a total of 105 (96.40 %) patients, it was established in a total of 97 (88.18 %) patients with antibiotic therapy, within the demographic aspect of the urban area 56 (50.90 %) patients and rural 54 (49.1 %). Conclusion: respiratory tract infection was the most frequent infection, the predominant risk factor is the use of corticosteroids and they received antibiotic therapy, which in monotherapy was the most used.

RESUMEN

Abstract Objectives: to study the side effects and the risk of disease flare after COVID-19 vaccination in Brazilian patients with Systemic Lupus erythematosus (SLE). Materials and methods: this retrospective study investigated a sample of 101 SLE patients for disease activity through the SLE disease activity index (SLEDAI) prior to and after two vaccine doses against SARS-COv-2. Side effects after vaccination were recorded. Results: in this sample, patients receiving two doses of the same vaccine were 10.3% for CoronaVAc; 42.2% for Pfizer, and 47.3% for Astra-Zeneca. Side effects were detected in 76.2% of them, and most of them were mild and moderate; the most common were local pain (62.3%), headache (36.6%), and fatigue (34.6%). The SLEDAI prior to the first dose and after the second dose did not change significantly (p=0.68). Only 4.1% of individuals had increased in SLEDAI ≥than 3 points. Conclusions: vaccination against COVID-19 was well tolerated and safe in SLE patients.

Resumen Objetivos: estudiar los efectos secundarios y el riesgo de exacerbación de la enfermedad después de la vacunación COVID-19 en una muestra de pacientes con lupus eritematoso sistémico (LES). Materiales y métodos: estudio retrospectivo que investigó 101 pacientes con LES. Se determinó la actividad de la enfermedad mediante el Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) antes y después de dos dosis de la vacuna contra el SARS-COv-2. Se registraron los efectos secundarios después de la vacunación. Resultados: los pacientes que recibieron dos dosis de la misma vacuna fueron el 10,3% para CoronaVAc, el 42,2% para Pfizer y el 47,3% para AstraZeneca. Se detectaron efectos secundarios en el 76,2% y la mayoría fue leve/moderado. Los más frecuentes fueron: dolor local (62,3%), cefalea (36,6%) y fatiga (34,6%). El cambio en la mediana del SLEDAI antes de la primera dosis y después de la segunda no fue estadísticamente significativo (p=0,68). Solo el 4,1% de los individuos aumentó el SLEDAI ≥ de 3 puntos. Conclusiones: la vacunación contra la COVID-19 fue bien tolerada y segura en pacientes con LES.

RESUMEN

BACKGROUND: Hemicrania continua is a rare form of cephalalgia featuring a chronic and persistent headache in only one side of the head. OBJECTIVES: In this report, we present a case of a patient with hemicrania continua and systemic lupus erythematosus (SLE). METHODS: We collected patient data through the electronic medical record. Afterward, we reviewed the literature regarding hemicrania continua and its pathophysiology and correlation with neurovascular alterations, inflammation, and SLE. RESULTS: A 42-year-old woman visited the emergency department due to worsening constant unilateral cephalalgia that had been present for the past 6 months. The patient reported a highly intense (10/10) headache in the entire left hemicrania that radiated to the left shoulder. During physical examination, she presented with nystagmus, vertigo, and aggravated cephalalgia associated to body movement and, despite having no optic nerve thickening. In addition, she had jaundice, tachycardia, and splenomegaly. Complimentary exams found deep anemia, depletion in complement system and anti-nuclear factors, suggesting a possible hemolytic anemia (AIHA) due to SLE. Treatment was initiated with hydrocortisone and prednisone, associated with amitriptyline, fluoxetine and diazepam, reaching full remission. CONCLUSION: These syndromes have aggravated each other, and possibly the explanation for the cephalalgia remission was the control of AIHA and SLE. It features a rare case in literature and thus warrants discussion.

INTRODUÇÃO: Hemicrania contínua é uma forma rara de cefaléia caracterizada por cefaleia crônica e persistente em apenas um lado da cabeça. OBJETIVOS: Neste relato apresentamos o caso de um paciente com hemicrania contínua e lúpus eritematoso sistêmico (LES). MÉTODOS: Coletamos dados dos pacientes por meio do prontuário eletrônico. Posteriormente, revisamos a literatura sobre a hemicrania contínua e sua fisiopatologia e correlação com alterações neurovasculares, inflamação e LES. RESULTADOS: Uma mulher de 42 anos recorreu ao serviço de urgência devido ao agravamento da cefaleia unilateral constante, presente nos últimos 6 meses. O paciente relatou cefaleia de alta intensidade (10/10) em toda a hemicrânia esquerda com irradiação para o ombro esquerdo. Ao exame físico apresentava nistagmo, vertigem e cefaléia agravada associada à movimentação corporal e, apesar de não apresentar espessamento do nervo óptico. Além disso, ela apresentava icterícia, taquicardia e esplenomegalia. Os exames complementares evidenciaram anemia profunda, depleção do sistema complemento e fatores antinucleares, sugerindo uma possível anemia hemolítica (AIHA) por LES. Iniciou-se tratamento com hidrocortisona e prednisona, associadas a amitriptilina, fluoxetina e diazepam, atingindo remissão completa. CONCLUSÃO: Essas síndromes agravaram-se mutuamente e possivelmente a explicação para a remissão da cefaléia foi o controle da AIHA e do LES. Apresenta um caso raro na literatura e, portanto, merece discussão.

RESUMEN

ABSTRACT Objective: To understand the meanings attributed to pregnancy in the context of Lupus and antiphospholipid syndrome by women and healthcare professionals. Method: Qualitative research, using Symbolic Interactionism as a theoretical framework and Grounded Theory, a constructivist perspective. Data were collected between January and August 2022, through online interviews with 27 women with Lupus located on the social network Facebook and in-person or remote interviews with 12 healthcare professionals. Results: The theoretical model constructed has two categories: "Equal conditions, distinct experiences: experiencing the gestational process" shows that obstetric complications and lack of connection with healthcare professionals trigger negative meanings to the experience; and "Therapeutic management interfering in the attribution of meanings to the experience", demonstrates that the way women interact with healthcare professionals and how they manage treatment favors a positive reframing. Final considerations: The meanings attributed to pregnancy are elaborated and modified according to the interpretation of previous and current experiences, healthcare trajectory and interactions with healthcare professionals. Previous guidance, planning, bonding and trust in healthcare professionals enable positive meanings, while obstetric complications, unqualified assistance and lack of bonding with professionals provide negative meanings.

RESUMEN Objetivo: Comprender los significados atribuidos al embarazo en el contexto del Lupus y del síndrome antifosfolípido por mujeres y profesionales de la salud. Método: Investigación cualitativa, que utilizó como marco teórico el Interaccionismo simbólico y metodológico, la Teoría Fundamentada, una vertiente constructivista. Los datos fueron recolectados entre enero y agosto de 2022, a través de entrevistas online a 27 mujeres con Lupus ubicadas en la red social Facebook y entrevistas presenciales o remotas a 12 profesionales de la salud. Resultados: El modelo teórico construido tiene dos categorías: "Condiciones iguales, experiencias diferentes: vivir el proceso gestacional" muestra que las complicaciones obstétricas y la falta de conexión con los profesionales de la salud desencadenan significados negativos a la experiencia; y Gestión terapéutica interfiriendo en la atribución de significados", demuestra que la forma en que las mujeres interactúan con los profesionales de la salud y cómo conducen el tratamiento favorece la resignificación positiva.. Consideraciones finales: Los significados atribuidos al embarazo son elaborados y modificados según la interpretación de experiencias pasadas y actuales, trayectoria de atención e interacciones con profesionales de la salud. La orientación previa, la planificación, la vinculación y la confianza en los profesionales de la salud posibilitan significados positivos, mientras que las complicaciones obstétricas, la asistencia no calificada y la falta de vínculo con los profesionales proporcionan significados negativos.

RESUMO Objetivo: Compreender os significados atribuídos à gravidez, no contexto do Lúpus e da Síndrome Antifosfolípide, por mulheres e profissionais de saúde. Método: Pesquisa qualitativa, que utilizou como referencial teórico o Interacionismo simbólico e metodológico, a Teoria Fundamentada nos Dados, vertente construtivista. Os dados foram coletados entre janeiro e agosto de 2022, mediante entrevistas on-line com 27 mulheres com Lúpus, localizadas na rede social Facebook e em entrevistas presenciais ou remotas com 12 profissionais de saúde. Resultados: O modelo teórico construído possui duas categorias: "Condições iguais, experiências distintas: vivenciando o processo gestacional" mostra que complicações obstétricas e ausência de vínculo com os profissionais de saúde desencadeiam significados negativos à experiência; e "O manejo terapêutico interferindo na atribuição dos significados à experiência" demonstra que a forma com que a mulher interage com os profissionais de saúde e conduz o tratamento favorece a ressignificação positiva. Considerações finais: Os significados atribuídos à gestação são elaborados e modificados conforme a interpretação de experiências anteriores e atuais, trajetória assistencial e interações com os profissionais de saúde. A orientação prévia, o planejamento, o vínculo e a confiança nos profissionais de saúde possibilitam significados positivos. Já, as complicações obstétricas, a assistência não qualificada e ausência de vínculo com os profissionais produzem significados negativos.

RESUMEN

ABSTRACT Objective: to learn the meanings attributed to pregnancy loss by women with Lupus. Method: qualitative research, based on Symbolic Interactionism and Grounded Theory. Data collection took place between January and August 2022 through in-depth interviews. Data analysis went through the stages of initial and focused coding. Results: seventeen women participated. The central phenomenon "The climb to motherhood: falls and overcoming" was constructed, consisting of three categories: "Falling to the ground during the climb: the experience of pregnancy loss"; "Getting up and following the path: new attempts to conceive"; and "Remembering the journey: meanings attributed to pregnancy losses". Final considerations: experiencing pregnancy is, analogously, like climbing a mountain, where obstacles need to be overcome to reach the summit. The experience of pregnancy loss is seen as complex, especially when there is fragility in healthcare and a lack of awareness regarding feelings of loss and grief.

RESUMEN Objetivo: comprender los significados atribuidos a la pérdida del embarazo por mujeres con Lupus. Método: investigación cualitativa, basada en el Interaccionismo Simbólico y la Teoría Fundamentada en Datos. La recolección de datos se realizó entre enero y agosto de 2022, mediante entrevistas en profundidad. El análisis de datos pasó por las etapas de codificación inicial y focalizada. Resultados: participaron 17 mujeres. Se construyó el fenómeno central "La subida a la maternidad: caídas y superación", conformado por tres categorías: "Caer al suelo durante la subida: la experiencia de la pérdida del embarazo"; "Levantarse y seguir el camino: nuevos intentos de concebir"; y "Recordando el viaje: significados atribuidos a las pérdidas de embarazos". Consideraciones finales: vivir el embarazo es, análogamente, como escalar una montaña, donde es necesario superar obstáculos para llegar a la cima. La experiencia de la pérdida del embarazo se considera compleja, especialmente cuando hay fragilidad en la atención de salud y falta de conciencia sobre los sentimientos de pérdida y duelo.

RESUMO Objetivo: apreender os significados atribuídos à perda gestacional por mulheres com lúpus. Método: pesquisa qualitativa, pautada no Interacionismo Simbólico e na Teoria Fundamentada nos Dados. A coleta de dados ocorreu entre janeiro e agosto de 2022, mediante entrevistas em profundidade. A análise de dados percorreu as etapas de codificação inicial e focalizada. Resultados: participaram 17 mulheres. Construiu-se o fenômeno central "A escalada da maternidade: quedas e superações", constituído por três categorias: "Caindo ao chão durante a subida: a vivência da perda gestacional"; "Levantando e seguindo o caminho: novas tentativas de gestar"; e "Rememorando o percurso: significados atribuídos às perdas gestacionais". Considerações finais: vivenciar a gestação é, analogicamente, como escalar uma montanha, onde obstáculos precisam ser vencidos até o alcance do cume. A vivência de perdas gestacionais é significada como complexa, em especial quando há fragilidade na assistência à saúde e falta de sensibilização diante dos sentimentos de perda e luto.

RESUMEN

El lupus eritematoso sistémico (LES) es una enfermedad inflamatoria autoinmune sistémica de causa desconocida, con heterogeneidad en su presentación clínica, así como una variabilidad en su curso clínico y pronóstico. El objetivo actual del tratamiento es conseguir la remisión de la enfermedad o al menos un estado de baja actividad, y por consiguiente mejorar la calidad de vida del paciente. La terapia biológica en el lupus, a diferencia de otras entidades, si bien no ha conseguido instaurarse plenamente, ha irrumpido en los últimos años con novedades terapéuticas importantes. En esta revisión se pretende actualizar las herramientas terapéuticas del tratamiento del LES enfocado a las nuevas moléculas que han conseguido superar los objetivos de sus ensayos clínicos (AU)

Systemic lupus erythematosus (SLE) is a systemic autoimmune inflammatory disease of unknown cause, with heterogeneity in its clinical presentation, as well as variability in its clinical course and prognosis. The current goal of treatment is to achieve disease remission or a state of low activity, and thereby improve the patient's quality of life. Biological therapy in lupus, unlike other entities, although it has not been fully established, in recent years it has burst onto the scene with important therapeutic novelties. This review aims to update the therapeutic tools for the treatment of SLE focusing on the new molecules that have achieved the objectives of their clinical trials (AU)
