Rate of severe and fatal infections in a cohort of patients with interstitial lung disease associated with rheumatoid arthritis: a multicenter prospective study.

Objective: To describe severe infection, foci of infection, microorganisms, associated factors, and impact on mortality in patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD). Patients and methods: The study was based on a multicenter prospective cohort of patients with RA-ILD followed up from 2015 to 2023. The main outcome measures were incident severe infection and fatal infection. We evaluated infectious foci, etiologic agents, vaccination status, variables associated with lung function, and clinical-therapeutic variables in RA. The incidence rate (IR) for infection and mortality was calculated per 100 person-years, and 3 multivariate models were constructed to explore factors associated with infection. Results: We followed up 148 patients with RA-ILD for a median 56.7 months (699.3 person-years). During this period, 142 patients (96%) had at least 1 infection. A total of 368 infectious episodes were recorded, with an IR of 52.6 per 100 person-years. Of the 48 patients who died, 65% did so from infection. Respiratory infections were the most common first infection (74%), infection overall (74%), and fatal infection (80%) and were caused mostly by SARS CoV-2, Streptococcus pneumoniae, Pseudomonas aeruginosa, and influenza A virus. The factors associated with an increased risk of infection and death in patients with RA-ILD were age, inflammatory activity, and therapy with corticosteroids and immunosuppressants. Conclusion: Patients with RA-ILD have a high risk of serious infection, especially respiratory infection. Infection develops early, is recurrent, and is frequently fatal. The presence of associated factors such as advanced age, joint inflammation, and treatment highlight the importance of integrated and preventive medical care.

Analysis of comorbidity in rheumatoid arthritis-associated interstitial lung disease: a nested case-cohort study.

OBJECTIVES: To describe comorbid conditions in patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and to analyze factors associated with multimorbidity. METHODS: Nested case-cohort study of 2 prospective cohorts: one with RA-ILD (cases) and another with RA but not ILD (controls). The cohorts were matched for age, sex, and time since diagnosis. Multimorbidity was defined as the co-occurrence of 2 or more chronic diseases, in addition to RA and ILD. We evaluated the comorbid conditions included in the Charlson Comorbidity Index, cardiovascular risk factors, neuropsychiatric conditions, and other frequent conditions in RA. We also recorded clinical-laboratory variables, inflammatory activity according to the 28-joint Disease Activity Score, C-reactive protein (CRP), physical function, and pulmonary function. We performed 2 multivariate analyses to identify factors associated with multimorbidity in RA and RA-ILD. RESULTS: The final study population comprised 110 cases and 104 controls. Multimorbidity was more frequent among cases than controls (80 [72.7] vs 60 [57.7]; p = 0.021). In both groups, multimorbidity was associated with ILD (OR [95% CI] 1.92 [1.03-3.59]; p = 0.039), age (OR [95% CI] 1.05 [1.01-1.08]; p = 0.004), CRP (OR [95% CI] 1.16 [1.05-1.29]; p = 0.003), and erosions (OR [95% CI] 1.05 [1.01-1.08]; p = 0.004); in the cases, it was associated with CRP (OR [95% CI] 1.17 [1.01-1.35]; p = 0.027), anti-citrullinated peptide antibody (OR [95% CI] 1.23 [1.14-13.02]; p = 0.049), and forced vital capacity (OR [95% CI] 0.79 [0.96-0.99]; p = 0.036). CONCLUSION: In patients with RA, multimorbidity was associated with ILD, systemic inflammation, and advanced age.

Hospitalizaciones y mortalidad por COVID-19 en pacientes con enfermedades inflamatorias reumáticas en Andalucía / Hospitalization and Mortality from COVID-19 of Patients with Rheumatic Inflammatory Diseases in Andalusia

Objetivo: Describir si las enfermedades inflamatorias reumáticas (EIR) se asocian con mayor riesgo de hospitalización y/o mortalidad por COVID-19 e identificar los factores asociados a la hospitalización y mortalidad en EIR y COVID-19 en diferentes hospitales de Andalucía.Métodos: Diseño: Estudio multicéntrico observacional de casos y controles.Pacientes Casos: EIR y COVID-19 de diferentes centros de Andalucía. Controles: pacientes sin EIR pareados por sexo, edad y PCR-COVID.Protocolo: Se solicitó al Servicio de Microbiología un listado de pacientes con PCR para COVID-19 desde 14 de marzo al 14 de abril de 2020. Se identificaron los pacientes que tuvieran EIR y luego consecutivamente un control pareado para cada caso. Variables La variable de desenlace principal fue ingreso hospitalario y mortalidad por COVID-19. Análisis estadístico Bivariante seguida de modelos de regresión logística binaria (variable dependiente: mortalidad/ingreso hospitalario).Resultados: Se incluyeron 156 pacientes con COVID-19, 78 con EIR y 78 sin EIR. Los pacientes con EIR no presentaron características de la enfermedad COVID-19 diferentes a la población general, tampoco mayor ingreso hospitalario ni mortalidad. El factor asociado con mortalidad en los pacientes con EIR fue edad (OR [IC 95%], 1,1 [1,0-1,2]; p = 0,025), mientras que los factores asociados con ingreso hospitalario fueron edad (OR [IC 95%], 1,1 [1,1-1,2]; p = 0,007) e hipertensión arterial (OR [IC 95%], 3,9 [1,5-6,7]; p = 0,003).Conclusión: La mortalidad y el ingreso hospitalario por COVID-19 no parecen aumentados en las EIR. La edad se asoció con mortalidad en EIR y, además, la hipertensión arterial se asoció con ingreso hospitalario.(AU)

Objective: To describe whether rheumatic inflammatory diseases (RID) are associated with a higher risk of hospitalization and/or mortality from COVID-19 and identify the factors associated with hospitalization and mortality in RID and COVID-19 in different Hospitals in Andalusia. Methods: Design: Multicentre observational case-control study. Patients: RID and COVID-19 from different centres in Andalusia. Controls: patients without RIS matched by sex, age and CRP-COVID. Protocol A list of patients with PCR for COVID-19 was requested from the microbiology service from March 14 to April 14, 2020. The patients who had RID were identified and then consecutively a paired control for each case. Variables The main outcome variable was hospital admission and mortality from COVID-19. Statistical analysis Bivariate followed by binary logistic regression models (DV: mortality/hospital admission).Results: One hundred and fifty-six patients were included, 78 with RID and COVID-19 and 78 without RID with COVID-19. The patients did not present characteristics of COVID-19 disease different from the general population, nor did they present higher hospital admission or mortality. The factor associated with mortality in patients with RID was advanced age (OR [95% CI], 1.1 [1.0-1.2]; p = 0.025), while the factors associated with hospitalization were advanced age (OR [95% CI], 1.1 [1.0-1.1]; p = 0.007) and hypertension (OR [95% CI], 3.9 [1.5-6.7]; p = 0.003).Conclusion: Mortality and hospital admission due to COVID-19 do not seem to increase in RID. Advanced age was associated with mortality in RID and, in addition, HTN was associated with hospital admission.(AU)

Safety and Effectiveness of Abatacept in a Prospective Cohort of Patients with Rheumatoid Arthritis-Associated Interstitial Lung Disease.

OBJECTIVE: To prospectively evaluate the safety and efficacy profile of abatacept in patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD). METHODS: We performed a prospective observational multicenter study of a cohort of patients with RA-ILD treated with abatacept between 2015 and 2021. Patients were evaluated using high-resolution computed tomography and pulmonary function tests at initiation, 12 months, and the end of follow-up. The effectiveness of abatacept was evaluated based on whether ILD improved, stabilized, progressed, or was fatal. We also evaluated factors such as infection, hospitalization, and inflammatory activity using the 28-joint Disease Activity Score with the erythrocyte sedimentation rate (DAS28-ESR). Cox regression analysis was performed to identify factors associated with progression of lung disease. RESULTS: The study population comprised 57 patients with RA-ILD treated with abatacept for a median (IQR) of 27.3 (12.2-42.8) months. Lung disease had progressed before starting abatacept in 45.6% of patients. At the end of follow-up, lung disease had improved or stabilized in 41 patients (71.9%) and worsened in 13 (22.8%); 3 patients (5.3%) died. No significant decreases were observed in forced vital capacity (FVC) or in the diffusing capacity of the lung for carbon monoxide (DLCO).The factors associated with progression of RA-ILD were baseline DAS28-ESR (OR [95% CI], 2.52 [1.03-3.12]; p = 0.041), FVC (OR [95% CI], 0.82 [0.70-0.96]; p = 0.019), and DLCO (OR [95% CI], 0.83 [0.72-0.96]; p = 0.018). Only 10.5% of patients experienced severe adverse effects. CONCLUSION: Pulmonary function and joint inflammation stabilized in 71% of patients with RA-ILD treated with abatacept. Abatacept had a favorable safety profile.

Importance of Vaccination against SARS-CoV-2 in Patients with Interstitial Lung Disease Associated with Systemic Autoimmune Disease.

Objectives: To describe the frequency of COVID-19 and the effect of vaccination in patients with interstitial lung disease and systemic autoimmune disease (ILD-SAD) and to identify factors associated with infection and severity of COVID-19. Methods: We performed a cross-sectional multicenter study of patients with ILD-SAD followed between June and October 2021. The main variable was COVID-19 infection confirmed by a positive polymerase chain reaction (PCR) result for SARS-CoV-2. The secondary variables included severity of COVID-19, if the patient had to be admitted to hospital or died of the disease, and vaccination status. Other variables included clinical and treatment characteristics, pulmonary function and high-resolution computed tomography. Two logistic regression was performed to explore factors associated with "COVID-19" and "severe COVID-19". Results: We included 176 patients with ILD-SAD: 105 (59.7%) had rheumatoid arthritis, 49 (27.8%) systemic sclerosis, and 22 (12.54%) inflammatory myopathies. We recorded 22/179 (12.5%) SARS-CoV-2 infections, 7/22 (31.8%) of them were severe and 3/22 (13.22%) died. As to the vaccination, 163/176 (92.6%) patients received the complete doses. The factors associated with SARS-CoV-2 infection were FVC (OR (95% CI), 0.971 (0.946−0.989); p = 0.040), vaccination (OR (95% CI), 0.169 (0.030−0.570); p = 0.004), and rituximab (OR (95% CI), 3.490 (1.129−6.100); p = 0.029). The factors associated with severe COVID-19 were the protective effect of the vaccine (OR (95% CI), 0.024 (0.004−0.170); p < 0.001) and diabetes mellitus (OR (95% CI), 4.923 (1.508−19.097); p = 0.018). Conclusions: Around 13% of patients with ILD-SAD had SARS-CoV-2 infection, which was severe in approximately one-third. Most patients with severe infection were not fully vaccinated.

Efficacy and Safety of Rituximab in Autoimmune Disease-Associated Interstitial Lung Disease: A Prospective Cohort Study.

OBJECTIVES: To analyze the efficacy and safety of rituximab (RTX) in connective tissue disease associated with interstitial lung disease (CTD-ILD). METHODS: We performed a multicenter, prospective, observational study of patients with CTD-ILD receiving rituximab between 2015 and 2020. The patients were assessed using high-resolution computed tomography and pulmonary function tests at baseline, at 12 months, and at the end of follow-up. The main outcome measure at the end of follow-up was forced vital capacity (FVC) > 10% or diffusing capacity of the lungs for carbon monoxide (DLCO) > 15% and radiological progression or death. We recorded clinical characteristics, time to initiation of RTX, concomitant treatment, infections, and hospitalization. A Cox regression analysis was performed to identify factors associated with worsening ILD. RESULTS: We included 37 patients with CTD-ILD treated with RTX for a median (IQR) of 38.2 (17.7-69.0) months. At the end of the follow-up, disease had improved or stabilized in 23 patients (62.1%) and worsened in seven (18.9%); seven patients (18.9%) died. No significant decline was observed in median FVC (72.2 vs. 70.8; p = 0.530) or DLCO (55.9 vs. 52.2; p = 0.100). The multivariate analysis showed the independent predictors for worsening of CTD-ILD to be baseline DLCO (OR (95% CI), 0.904 (0.8-0.9); p = 0.015), time to initiation of RTX (1.01 (1.001-1.02); p = 0.029), and mycophenolate (0.202 (0.04-0.8); p = 0.034). Only 28 of the 37 patients (75.6%) were still undergoing treatment with RTX: two patients (5.4%) stopped treatment due to adverse events and seven patients (18.9%) died owing to progression of ILD and superinfection. CONCLUSION: Lung function improved or stabilized in more than half of patients with CTD-ILD treated with RTX. Early treatment and combination with mycophenolate could reduce the risk of progression of ILD.

Hospitalization and mortality from COVID-19 of patients with rheumatic inflammatory diseases in Andalusia.

OBJECTIVE: To describe whether rheumatic inflammatory diseases (RID) are associated with a higher risk of hospitalization and/or mortality from COVID-19 and identify the factors associated with hospitalization and mortality in RID and COVID-19 in different Hospitals in Andalusia. METHODS: Design: Multicentre observational case-COntrol study. PATIENTS: RID and COVID-19 from different centres in Andalusia. CONTROLS: patients without RIS matched by sex, age and CRP-COVID. Protocol A list of patients with PCR for COVID-19 was requested from the microbiology service from March 14 to April 14, 2020. The patients who had RID were identified and then consecutively a paired control for each case. Variables The main outcome variable was hospital admission and mortality from COVID-19. Statistical analysis Bivariate followed by binary logistic regression models (DV: mortality/hospital admission). RESULTS: One hundred and fifty-six patients were included, 78 with RID and COVID-19 and 78 without RID with COVID-19. The patients did not present characteristics of COVID-19 disease different from the general population, nor did they present higher hospital admission or mortality. The factor associated with mortality in patients with RID was advanced age (OR [95% CI], 1.1 [1.0-1.2]; P= .025), while the factors associated with hospitalization were advanced age (OR [95% CI], 1.1 [1.0-1.1]; P = .007) and hypertension (OR [95% CI], 3.9 [1.5-6.7]; P = .003). CONCLUSION: Mortality and hospital admission due to COVID-19 do not seem to increase in RID. Advanced age was associated with mortality in RID and, in addition, HTN was associated with hospital admission.

Characteristics and Predictors of Progression Interstitial Lung Disease in Rheumatoid Arthritis Compared with Other Autoimmune Disease: A Retrospective Cohort Study.

OBJECTIVES: To describe the characteristics and progression of interstitial lung disease in patients with associated systemic autoimmune disease (ILD-SAI) and to identify factors associated with progression and mortality. PATIENTS AND METHODS: We performed a multicenter, retrospective, observational study of patients with ILD-SAI followed between 2015 and 2020. We collected clinical data and performed pulmonary function testing and high-resolution computed tomography at diagnosis and at the final visit. The main outcome measure at the end of follow-up was forced vital capacity (FVC) >10% or diffusing capacity of the lungs for carbon monoxide >15% and radiological progression or death. Cox regression analysis was performed to identify factors associated with worsening of ILD. RESULTS: We included 204 patients with ILD-SAI: 123 (60.3%) had rheumatoid arthritis (RA), 58 had (28.4%) systemic sclerosis, and 23 (11.3%) had inflammatory myopathy. After a median (IQR) period of 56 (29.8-93.3) months, lung disease had stabilized in 98 patients (48%), improved in 33 (16.1%), and worsened in 44 (21.5%). A total of 29 patients (14.2%) died. Progression and hospitalization were more frequent in patients with RA (p = 0.010). The multivariate analysis showed the independent predictors for worsening of ILD-SAI to be RA (HR, 1.9 [95% CI, 1.3-2.7]), usual interstitial pneumonia pattern (HR, 1.7 [95% CI, 1.0-2.9]), FVC (%) (HR, 2.3 [95% CI, 1.4-3.9]), and smoking (HR, 2.7 [95%CI, 1.6-4.7]). CONCLUSION: Disease stabilizes or improves after a median of 5 years in more than half of patients with ILD-SAI, although more than one-third die. Data on subgroups and risk factors could help us to predict poorer outcomes.

CONCLUSION: Mortality and hospital admission due to COVID-19 do not seem to increase in RID. Advanced age was associated with mortality in RID and, in addition, HTN was associated with hospital admission.

Predictors of Progression and Mortality in Patients with Prevalent Rheumatoid Arthritis and Interstitial Lung Disease: A Prospective Cohort Study.

OBJECTIVES: To describe a prospective cohort of patients with rheumatoid arthritis associated with interstitial lung disease (RA-ILD) and identify risk factors associated with disease progression and mortality in this cohort. PATIENTS AND METHODS: We performed a multicenter, prospective, observational study of patients with RA-ILD receiving disease-modifying antirheumatic drugs (DMARDs) between 2015 and 2020. The patients were assessed using high-resolution computed tomography and pulmonary function tests at baseline and at 60 months. The main endpoint was "Progression to ILD at the end of follow-up" in terms of the following outcomes: (1) improvement (i.e., improvement in forced vital capacity (FVC) ≥10% or diffusing capacity of the lungs for carbon monoxide (DLCO) ≥15% and absence of radiological progression); (2) nonprogression (stabilization or improvement in FVC ≤10% or diffusing capacity of the lungs for carbon monoxide (DLCO) <15% and absence of radiological progression); (3) progression (worsening of FVC >10% or DLCO >15% and radiological progression); or (4) death. We recorded demographic and clinical characteristics, lung function, and the incidence of adverse events. A Cox regression analysis was performed to identify factors associated with the worsening of ILD. RESULTS: After 60 months, lung disease had stabilized in 66 patients (56.9%), improved in 9 (7.8%), and worsened in 23 (19.8%). Eighteen patients (15.5%) died, with a mean survival of 71.8 (1.9) months after diagnosis of ILD. The Cox multivariate analysis revealed the independent predictors of worsening of RA-ILD to be usual interstitial pneumonia (hazard ratio (HR), 2.6 (95%CI, 1.0-6.7)), FVC <80% (HR, 3.8 (95%CI, 1.5-6.7)), anticitrullinated protein antibody titers (HR, 2.8 (95%CI, 1.1-6.8)), smoking (HR, 2.5 (95%CI, 1.1-6.2)), and treatment with abatacept, tocilizumab, or rituximab (HR, 0.4 (95%CI, 0.2-0.8)). During follow-up, 79 patients (68%) experienced an adverse event, mostly infection (61%). Infection was fatal in 10/18 patients (55.5%) during follow-up. CONCLUSIONS: Lung function is stable in most patients with RA-ILD receiving treatment with disease-modifying anti-rheumatic drugs (DMARDs), although one-third worsened or died. Identifying factors associated with worsening in RA-ILD is important for clinical management.

Hormonal Dependence and Cancer in Systemic Lupus Erythematosus.

OBJECTIVE: To estimate the incidence and analyze any cancer-associated factors in patients with systemic lupus erythematosus (SLE), differentiating between hormone-sensitive (HS) and non-HS cancers. METHODS: This was a retrospective multicenter study of a patient cohort from the Systemic Lupus Erythematosus Registry of the Spanish Society of Rheumatology. Included were the first cancer post-SLE diagnosis, clinical and sociodemographic information, cumulative damage, severity, comorbidities, treatments, and refractoriness. Cancers were classified as HS (prostate, breast, endometrium, and ovarian) and non-HS (the remainder). The standardized incidence ratio (SIR) was calculated and logistic regression models were built. RESULTS: A total of 3,539 patients (90.4% women) were included, 154 of whom had cancer (91% female), and 44 had HS cancer (100% female). The cancer SIR was 1.37 (95% confidence interval [95% CI] 1.15-1.59), with higher values in women age <65 years (SIR 2.38 [95% CI 1.84-2.91]). The SIR in women with HS versus non-HS cancer was 1.02 (95% CI 0.13-1.91) and 1.93 (95% CI 0.98-2.89). In HS versus non-HS cancers, SLE diagnostic age (odds ratio [OR] 1.04 [P = 0.002] versus 1.04 [P = 0.019]), and period of disease evolution (OR 1.01 [P < 0.001] versus 1.00 [P = 0.029]) were associated with cancer. The Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (OR 1.27 [P = 0.022]) and angiotensin-converting enzyme (ACE) inhibitor prescriptions (OR 2.87 [P = 0.048]) were associated with non-HS cancers. CONCLUSION: Cancer incidence in patients with SLE was higher than in the Spanish population, particularly among young women. This increase might be due to non-HS cancers, which would be associated with SLE involving greater cumulative damage where more ACE inhibitors are prescribed.

Pseudotumor orbitario refractario tratado con rituximab en paciente con lupus eritematoso sistémico. A propósito de un caso / Resistant orbital pseudotumor treated with rituximab in ap atient with systemic lupus erythematosus. A case presentation

Las manifestaciones oculares en el lupus eritematoso sistémico (LES) son relativamente frecuentes, con mayor prevalencia de la queratoconjuntivitis seca. Sin embargo, la aparición de exoftalmos unilateral secundario a pseudotumor orbitario en pacientes con LES es extremadamente rara 1–7, y en ocasiones puede presentarse refractaria al tratamiento farmacológico convencional (glucocorticoides e inmunosupresores). A continuación presentamos el caso de una paciente con LES y pseudotumor orbitario refractario a tratamiento con ciclofosfamida y excelente respuesta clínica con desaparición de la clínica oftalmológica tras el inicio de la terapia con rituximab(1gx2), eficacia mantenida tras la infusión de dos ciclos completos sin incidencias (AU)

Ocular manifestations in Systemic Lupus Erythematosus(SLE)are relatively frequent, with a major prevalence of the Keratoconjunctivitis sicca. Nevertheless, the appearance of unilateral exophthalmos secondary to orbital pseudotumor in patients with SLE is extremely rare 1–7, and on occasion it can be refractory to conventional pharmacological treatment(glucocorticoids and immunosuppressants). We present the case of a patient with SLE and orbital pseudotumor refractory to treatment with Cyclophosphamide(CF) and an excellent clinical response, with disappearance of the ophthalmological condition after the beginning of the rapy with Rituximab (1gx2), continuing after the infusion of two complete cycles without incidents (AU)

Síndrome nefrótico en esclerodermia / Nephrotic syndrome in Scleroderma

La afección renal es infrecuente en la esclerosis sistémica, a diferencia de otras colagenosis. La aparición de síndrome nefrótico se ha relacionado con el uso de fármacos, especialmente la D-penicilamina, o raramente como manifestación de amiloidosis secundaria, bastante infrecuente en la esclerosis sistémica. Presentamos un caso de síndrome nefrótico en una paciente con esclerosis sistémica, producido por una glomerulonefritis membranosa, descrito de forma excepcional en la literatura (AU)

The renal affectation is infrequent in scleroderma, unlike other collagen diseases. The appearance of nephrotic syndrome has been related to the drug use, specially the D-penicilamine, or rarely as a manifestation of secondary amilodosis, quite infrequent in scleroderma. We report a case of nephrotic syndrome in a patient with systemic scleroderma, produced by a membranous glomerulonephritis, exceptionally described in literature (AU)

Mielitis transversa en lupus eritematoso sistémico / Transverse myelitis in systemic lupus erythematosus

Objetivo: La mielitis transversa aguda (MTA) es una rara complicación en los pacientes con lupus eritematoso sistémico (LES). Revisamos nuestra serie de pacientes con LES para determinar la prevalencia de MTA y analizar las características clínicas, las pruebas complementarias, la evolución y la respuesta al tratamiento. Pacientes y método: Se identificó a 6 pacientes con MTA que se sometieron a valoración clínico-neurológica, resonancia magnética y estudio electrofisiológico y recibieron el mismo tratamiento. Realizamos un estudio estadístico descriptivo. Resultados: Observamos una prevalencia de MTA del 0,92% de nuestros pacientes con LES. El 83,3% presentaba anticuerpos antifosfolipídicos y/o anticoagulante lúpico. La resonancia magnética confirmó el diagnóstico en 5 de los 6 casos; 3 de los 5 pacientes con anticuerpos antifosfolipídicos fueron anticoagulados o antiagregados, con buena evolución neurológica; 2 de ellos han quedado sin secuelas. Conclusiones: Encontramos una prevalencia similar a la observada en otras series, en torno al 1%. La alta prevalencia de anticuerpos antifosfolipídicos en los pacientes, con buen resultado en los antiagregados o anticoagulados, indica un importante papel patogénico en el desarrollo de la MTA, y nos hace plantearnos la importancia de añadir al tratamiento estándar terapia antiagregante o anticoagulante (AU)

Objective: Transverse myelitis (TM) is a rare complication in patients with systemic lupus erithematosus (SLE). We reviewed a series of our SLE patients to determine the prevalence of TM, and evaluate the clinical characteristics, medical tests, evolution and response to the treatment. Patients and method: Six patients with TM were identified and underwent a neurological evaluation, MRI, electrophysiologic study and were all subjected to the same treatment. A descriptive statistical study was conducted. Results: We observed a prevalence of 0.92% in our patients with SLE. Eighty three point three per cert had antiphospholipid antibodies and/or lupus anticoagulant. The MRI confirmed the diagnosis in 5 cases. Of the 5 patients with antiphospholypid antibodies, 3 were anticoagulated or took aspirin with a good neurological outcome, leaving 2 of them without posterior complications. Conclusions: We found a prevalence similar to that observed in other series, around 1%. The high prevalence of antiphospholypid antibodies in these patients, with good outcome in those anticoagulated or treated with antiplatelet agents suggests an important pathogenic role in the development of TM, and emphasized the possibility of adding to the standard treatment, antiplatelet agents or anticoagulation (AU)
