RESUMO
PURPOSE: To assess the prevalence of autoimmune diseases (ADs) associated with ocular cicatricial pemphigoid (OCP) and analyze clinical, laboratory, and treatment associations between these entities. METHODS: A multicentre cross-sectional study of patients with an OCP diagnosis. The population was divided into two groups according to their association with other ADs or not. Clinical, laboratory and treatment variables were described and compared between groups. A multivariable logistic regression analysis was performed to identify variables that could suggest the association between OCP and ADs. RESULTS: Eighty-eight patients were recruited, with a mean age at diagnosis of 64.3 years (SD 11.9). Biopsy was performed in 86.8% of the patients. There was a median delay of 2 years from the onset of symptoms to diagnosis. Extraocular involvement was evidenced in 11.5%. The group associated with ADs included 24 patients (27.3%). The most prevalent diagnosis was Sjögren´s syndrome. Hypergammaglobulinemia was associated with ADs and OCP, adjusted for age, sex, smoking, skin and mucosal involvement, and erythrocyte sedimentation rate (OR 8.7; 95%CI 1.6-46.8; p = 0.012). CONCLUSIONS: Due to OCP's autoimmune nature, it could coexist with other ADs. This study observed that more than a quarter of the population presented with this association, and hypergammaglobulinemia could suggest it.

INTRODUCTION AND AIM: T-score bone mineral density (BMD) thresholds may influence guidance for treatment in patients under glucocorticoid (GC) therapy. Different BMD thresholds have been described but there is no international consensus. The aim of this study was to find a threshold to help in treatment decision-making in the population under GC therapy. METHODS: A working group representing three scientific societies from Argentina was convened. The first team was formed by specialists with expertise in glucocorticoid-induced osteoporosis (GIO) who voted according to summary of evidence. The second team was constituted by a methodology group who coordinated and supervised each stage. We conducted two systematic reviews to synthesize the evidence. The first included trials of drugs used in GIO to analyze the BMD cut-off used as inclusion criteria. In the second, we analyzed the evidence regarding the densitometric thresholds to discriminate between fractured and non-fractured patients under GC treatment. RESULTS: In the first review, 31 articles were included for qualitative synthesis and more than 90% of the trials included patients regardless of their densitometric T-score or range of osteopenia. In the second review, 4 articles were included and more than 80% of the T-scores were in the range -1.6 to -2.0. The summary of findings was analyzed and put to a vote. CONCLUSIONS: With more than 80% agreement of the voting expert panel, a T-score≤-1.7 was considered the most appropriate for treatment in postmenopausal women and men over 50 years of age under GC therapy. This study could help in treatment decision-making in patients under GC therapy without fractures but other fracture risk factors should certainly be considered.

ABSTRACT Ocular cicatricial pemphigoid (OCP) is a chronic, immune-mediated, bullous, cicatricial disease within the spectrum of mucocutaneous membranous pemphigoids (MMP). Although the diagnosis is often ophthalmological, due to the autoimmune nature of the pathology, it requires a joint approach with rheumatologists and immunologists. The objective of this narrative review was to explore the evidence available in the literature from 2000 to 2020 with respect to clinical manifestations, diagnosis, and treatment. The clinical presentation varies widely, from mild cases with slow progression of years of progression, to severe cases with a torpid and rapidly progressive evolution to fibrosis, refractory to multiple treatments. A com plete evaluation of the patient will help guide the diagnosis. The gold standard for diagnosis is conjunctival biopsy with direct immunofluorescence, although on occasions it can be reached if the symptoms are characteristic. Treatment is local and systemic according to its severity and evolution. The evidence on topical and systemic therapeutics is obtained mainly from uncontrolled observational and experimental studies. Immunomodulatory therapy has made it possible to preserve vision and, in many cases, prevent sequelae. The evolu tion is linked to the early diagnosis and immunosuppressive treatment, so it is essential to be aware of this disease, the diagnostic methods, as well as the immunomodulating and immunosuppressive therapies available.
RESUMEN El penfigoide ocular cicatrizal (POC) es una enfermedad crónica, inmunomediada ampollar, mucosinequiante, comprendida dentro del espectro de penfigoides membranosos mucocutáneos (PMM). El diagnóstico es, con frecuencia, oftalmológico, pero debido al carácter autoinmune de la patología, requiere el abordaje en conjunto con reumatólogos e inmunólogos. El objetivo de esta revisión narrativa fue explorar la evidencia disponible en la literatura, desde el año 2000 hasta el 2020, en lo que respecta a sus manifestaciones clínicas, diagnóstico y tratamiento. La presentación clínica varía ampliamente, desde casos leves con progresión lenta de años de evolución hasta casos severos con evolución tórpida y rápidamente progresiva a la fibrosis, refractarios a múltiples tratamientos. Una evaluación completa del paciente ayudará a guiar el diagnóstico. El estándar de oro diagnóstico es la biopsia conjuntival con inmunofluorescencia directa, si bien en ocasiones puede diagnosticarse por la clínica característica. El tratamiento es local y sistêmico de acuerdo con su severidad y evolución. En los últimos 20 anos, la evidencia sobre los tratamientos tópicos y sistêmicos corresponde en su mayoría a estudios observacionales y experimentales no controlados. Los métodos de tratamiento inmunomoduladores han permitido preservar la visión y, en muchos casos, prevenir secuelas. La evolución está ligada al diagnóstico temprano y a los tratamientos disponibles, por lo que es fundamental el conocimiento de esta patología, los métodos diagnósticos y los tratamientos inmunomoduladores e inmunosupresores.

Introducción: los anti-TNF-α se asocian con mayor riesgo de desarrollar tuberculosis (TB). La prueba del derivado proteico purificado (purified protein derivative, PPD) se emplea para diagnosticar infección de tuberculosis latente (ITL). Se recomienda el cribado para TB previo al inicio de terapia anti-TNF-α y el seguimiento para evaluar la posible conversión de la PPD durante el tratamiento. El tratamiento de la ITL puede reducir el riesgo de desarrollar enfermedad activa en un 90%. Objetivos: actualmente los resultados de conversión de la PPD y su interpretación durante el tratamiento anti-TNF-α son variables, por tal motivo nos propusimos conocer la frecuencia de conversión de la PPD en este grupo de pacientes de nuestro medio. Materiales y métodos: realizamos un estudio descriptivo, observacional y retrospectivo que incluyó pacientes >18 años, diagnosticados con enfermedad reumática, tratados con anti-TNF-α. Resultados: se incluyeron 54 pacientes (46,7 ± a 12 años), de los cuales 36, presentaron diagnóstico de artritis reumatoidea, seis de artritis idiopática juvenil, cinco de espondilitis anquilosante, tres de artritis psoriásica, tres de uveítis y uno de queratitis intersticial. Los tratamientos fueron: 30 adalimumab, 17 certolizumab, siete etanercept, 44 metotrexato, 19 leflunomida, nueve hidroxicloroquina, dos sulfasalazina, dos azatioprina, uno mofetil micofenolato y glucocorticoides (28 de 54); la conversión de la PPD ocurrió en un solo paciente. Conclusiones: en el presente trabajo la seroconversión fue baja en contraste con otras series. La prueba de PPD es un método accesible, ampliamente disponible, adecuado y sensible para diagnosticar ITL.
Introduction: anti-TNF-α are associated with an increased risk of developing tuberculosis (TB). Purified protein derivative (PPD) is used to demonstrate a latent TB infection (LTBI). Screening is recommended for TB prior to the onset of anti-TNF-α and monitoring evaluating possible conversion of PPD during treatment. Treatment of LTBI can reduce the risk of active disease development by up to 90%. Objectives: currently the results of PPD conversion and its interpretation during anti-TNF-α treatment are variable and that is why we set out to know the frequency of conversion of PPD in this group of patients in our environment. Materials and methods: a descriptive, analytical, observational, retrospective study was conducted. Including patients >18 years old, diagnosed with rheumatic disease, treated with anti-TNF-α. Results: 54 patients were included (46.7 ± to 12 years), of which 36 presented a diagnosis of rheumatoid arthritis, 6 juvenile idiopathic arthritis, 5 ankylosing spondylitis, 3 psoriatic arthritis, 3 uveitis, 1 interstitial keratitis. The treatments were: 30 adalimumab, 17 certolizumab, 7 etanercept, 44 methotrexate, 19 leflunomide, 9 hydroxychloroquine, 2 sulfasalazine, 2 azathioprine, 1 mycophenolate mofetil and glucocorticoids (28/54). PPD conversion took place in 1 patient. Conclusions: in the present study, seroconversion was low in contrast to other series. The PPD test is an accessible, widely available, adequate and sensitive method for diagnosing LTBI, which the rheumatologist should use in his daily practice.

Evidence for Chagas disease reactivation (CDR) in rheumatologic patients under rheumatologic treatments (RTs) is scarce. To screen and follow-up patients with rheumatic diseases and concomitant Chagas disease under RT to detect CDR and to describe a possible relationship between CDR and specific RT. An observational, longitudinal, prospective, consecutive study was carried out between 2018 and 2020. Included patients were evaluated during the follow-up for clinical and laboratorial manifestations of CDR. Direct blood parasitological examination (Strout method) and polymerase chain reaction (PCR) were employed to diagnose CDR. The dynamic of anti-T. cruzi-specific antibodies was also assessed by IHA and ELISA (total IgG and Anti-SAPA). Fifty-one patients were included (86% women). Rheumatoid arthritis was the predominant disease (57%). Classic DMARDs (86.3%) and corticosteroids (61%) were the most frequent RT. CDR was developed in 6 patients (11.7%), exhibiting both positive Strout and PCR. Symptomatic reactivation of CD (fever, asthenia, arthralgias, myalgias) occurred in two patients who had previously been diagnosed with it. Regardless of the different RT, all patients who experienced CDR had previously received more than ≥ 20 mg/day of prednisone equivalent. Despite immunosuppression, patients with CDR exhibited increased levels of specific anti-T. cruzi and anti-SAPA antibodies, which decreased after anti-parasitic treatment. CDR is possible in rheumatologic patients, especially after receiving high doses of corticosteroids. Since CDR symptoms may mimic rheumatic disease activity, monitoring of Chagas disease is highly recommended before, during and after immunosuppression. Key Points ⢠Chagas disease reactivation (CDR) in the context of rheumatological treatment was associated to high doses of corticosteroids. ⢠CDR was associated with an increase in anti-T. cruzi antibodies despite the immunosuppressive treatment. ⢠Suspecting and anticipating CDR is mandatory in this patient population to diagnose and treat it.

Las manifestaciones cutáneas en las enfermedades autoinmunes son frecuentes y heterogéneas. En algunas de ellas, como en el caso del lupus eritematoso sistémico, la dermatomiositis, la esclerosis sistémica y el síndrome antifosfolípidico son de tal importancia que se incluyen como criterios clasificatorios de la enfermedad. Los diagnósticos diferenciales varían en gravedad, pudiendo en ocasiones presentar riesgo vital, por lo cual se jerarquizan el diagnóstico y tratamiento oportunos. Se describe el caso de una paciente de 22 años con diagnóstico previo de lupus eritematoso sistémico y síndrome antifosfolípídico, que concurre a la consulta con cuadro agudo caracterizado por lesiones cutáneas dolorosas de aspecto necrótico acompañadas de fiebre y livedo reticularis.
Cutaneous involvement is frequent and heterogeneous in autoimmune diseases. In some of them, such as in systemic lupus erythematosus, dermatomyositis, systemic sclerosis and antiphospholipid syndrome, some manifestations are so relevant that are included in the classification criteria. Differential diagnosis ranges in severity. Since the disease may be life-threatening, a prompt diagnosis and treatment are mandatory. We describe a clinical case of a twenty-two-year-old woman with diagnosis of systemic lupus erythematosus and antiphospholipidic syndrome, presenting with acute, painful cutaneous lesions with necrotic aspect, fever and livedo reticularis.

Biological therapies have represented a cornerstone in the treatment of immune-mediated inflammatory diseases. Their advent combined with implementation of a treat-to-target approach has meant that remission or low disease activity are now realistic targets for treatment achieved by a significant number of patients. However, biologicals are not risk free and their elevated costs continue to present an important economic burden to national healthcare services. "Can we wean patients with inflammatory arthritis from biological therapies?" Over the last decade this question has become increasingly important as to define the best management strategies in terms of efficacy, safety and economic outcomes. Not surprisingly this has generated an interesting debate as to whether reasons to taper biologics outweigh reasons not to taper and evidence in support of either of these schools of thought is persistently growing. AIM: In this article we reviewed the contents of the relevant session from the 2019 Controversies in Rheumatology and Autoimmunity meeting in Florence.
