ABSTRACT

2021.174934ABSTRACTIntroduction: The mechanisms by which hepatitis C virus (HCV) infection induces autoimmune thyroiditis (AIT) have been studied, and it was suggested that inflammatory cytokines during HCV infection would change the thy-roperoxidase (TPO) signaling cascade and thyroglobulin (Tg) determining autoimmune thyroid disease.Objective: To show the signaling pathway, of TPO and Tg, and their potential targets mediated HCV in individuals with hepatitis C.Methods: The mapping of the signaling pathway was based on a review study approach and performed using the automatic annotation server of the Kyoto and Genome Encyclopedia (KEGG). PathVisio is free software for analysis and design of open source routes, and was used for the graphic representation of the signaling pathway.Results: The contigs were extracted from the KEGG database and their mapped transcription represents the signa-ling pathway of the main biomolecules that triggers the AIT. The action of HCV, or its treatment can trigger AIT that is characterized by the presence of autoantibodies against TPO and Tg. In AIT, autoreactive CD4 + T lymphocytes recruit B cells and CD8 + T cells in the thyroid. The progression of the disease leads to the death of thyroid cells and hypothyroidism. Conclusion: HCV or its treatment activates several signaling pathways with thyroid cells damage resulting in AIT and secondary hypothyroidism to cellular apoptosis. (AU)


RESUMOIntrodução: Os mecanismos pelos quais a infecção com o vírus da hepatite C (HCV) induz à tireoidite autoimune (TAI) têm sido alvo de estudos. Tem sido sugerido que citocinas inflamatórias, como a elevação das interleucinas na inflamação causadas pelo HCV, alterariam a cascata de sinalização da tireoperoxidase (TPO) e tireoglobulina (Tg) determinando um quadro de doença autoimune da tireóide.Objetivo: Demonstrar a via de sinalização da TPO e da Tg e seus potenciais alvos para a TAI mediados pelo HCV em indivíduos com hepatite C.Método: O mapeamento da via de sinalização foi realizado usando o servidor de anotação automática da Enciclopé-dia Quioto de Genes e Genomas (KEGG). O PathVisio, um software gratuito de análise e desenho de vias de código aberto, foi utilizado para a representação gráfica da via de sinalização.Resultado: As sequências foram retiradas do banco de dados KEGG e sua transcrição mapeada representa a via de . sinalização das principais biomoléculas que desencadeia a TAI. A ação do HCV, ou seu tratamento pode desen-cadear a TAI que é caracterizada pela presença de autoanticorpos contra a TPO e Tg. Na TAI os linfócitos T CD4+ auto-reativos recrutam células B e células T CD8+ na tireóide. A progressão da doença leva à morte de células da tireóide e hipotireoidismo.Conclusão: O HCV ou o seu tratamento ativa várias vias de sinalização com dano na célula tireoidiana, tendo como resultado TAI e hipotireoidismo secundário a apoptose celular.

ABSTRACT

Abstract Autoimmune bullous dermatoses are a heterogeneous group of diseases with autoantibodies against structural skin proteins. Although the occurrence of autoimmune bullous dermatoses during pregnancy is low, this topic deserves attention, since the immunological and hormonal alterations that occur during this period can produce alterations during the expected course of these dermatoses. The authors review the several aspects of autoimmune bullous dermatoses that affect pregnant women, including the therapeutic approach during pregnancy and breastfeeding. Gestational pemphigoid, a pregnancy-specific bullous disease, was not studied in this review.

ABSTRACT

La pancreatitis recurrente ocurre en el 15-35% en la edad pediátrica. Se define como 2 o más episodios distintos de pancreatitis aguda con normalización de enzimas pancreáticas entre cada episodio. Una de sus causas es la pancreatitis autoinmune. En los últimos 10 años se controlaron, en el Hospital Garrahan, 10 pacientes con diagnóstico de pancreatitis recurrente, de los cuales solo uno tuvo diagnóstico de pancreatitis autoinmune. Se describe el caso clínico de una paciente, que, inicialmente, tenía estudios normales de función y anatomía pancreática y, en la evolución, luego de un episodio de pancreatitis aguda, desarrolló estenosis del conducto de Wirsung sugestiva de pancreatitis autoinmune. Se considera importante describir esta patología infrecuente en pediatría, pero que se encuentra en auge.


Introduction. Recurrent pancreatitis occurs in children between 15 and 35% of the cases. It is defined as two or more separate episodes of acute pancreatitis with normalization of the pancreatic enzymes between episodes. One of the causes is autoimmune pancreatitis. Over the last 10 years, 10 patients with recurrent pancreatitis were sent at our center. Only one was considered to have autoimmune pancreatitis. We described a clinical case about a patient, who had, at the beginning, normal functional and anatomical studies, and then was finally diagnosed with autoimmune disease based on findings on the magnetic resonance cholangiopancreatography with a duct of Wirsung abnormality. We considered important to describe this uncommon disorder in childhood, in spite of having an increasing incidence.

ABSTRACT

Introducción: La etiología de las enfermedades autoinmunes aún se desconoce, aunque se plantean diferentes causas. Objetivo: Describir el rol de factores como las hormonas, alimentación, estrés, enfermedades infecciosas y cáncer en las enfermedades autoinmunes. Métodos: Se realizó una revisión bibliográfica empleando Google Académico y artículos de libre acceso en la base de datos PubMed y SciELO, publicados entre enero del 2014 y junio del 2020. Se consultó la bibliografía nacional e internacional relevante y actualizada, con un total de 51 referencias, de estas, tres libros básicos de la especialidad de Inmunología y 48 artículos (12 en idioma español y 36 en inglés). Se utilizaron los términos de búsqueda según los descriptores del DeCS y MeSH. Resultados: Las hormonas femeninas incrementan el riesgo de las enfermedades autoinmunes. Un desbalance en la neurohormona melatonina puede generar linfocitos autorreactivos. El estrés puede mantener respuestas inflamatorias crónicas que causen daño tisular. Una adecuada alimentación permite que los comensales de la microbiota intestinal mantengan la homeostasis del sistema inmune. Las infecciones en ocasiones desarrollan respuestas autoinmunitarias. La causalidad entre el cáncer y la autoinmunidad es bidireccional producto de procesos inflamatorios. Conclusiones: Las enfermedades autoinmunes son más frecuentes en las mujeres. Una alimentación adecuada permite que la microbiota intestinal no se altere y que mantenga la homeostasis inmunológica. Situaciones de estrés e infecciones pueden iniciar respuestas autoinmunes. El cáncer puede favorecer el desarrollo de manifestaciones autoinmunes, y estas últimas por el predominio inflamatorio, favorecen la tumorogénesis(AU)


Introduction: The etiology of autoimmune diseases is still unknown, though several causes have been suggested. Objective: Describe the role of hormones, eating, stress, infectious diseases and cancer in immune diseases. Methods: A bibliographic review was conducted using Google Scholar and open access papers published in the databases Pubmed and SciELO from January 2014 to June 2020. Relevant updated national and international bibliography was consulted, for a total 51 references: three basic books from the specialty of immunology and 48 papers (12 in Spanish and 36 in English). The search terms used were obtained from the descriptors DeCS and MeSH. Results: Feminine hormones increase the risk of autoimmune diseases. Imbalance in the neurohormone melatonin may generate autoreactive lymphocytes. Stress may maintain chronic inflammatory responses causing tissue damage. Appropriate eating habits allow gut microbiota commensals to maintain the homeostasis of the immune system. Infections occasionally develop autoimmune responses. Causality between cancer and autoimmunity is bidirectional, due to the presence of inflammatory processes. Conclusions: Autoimmune diseases are more common among women. Appropriate eating habits prevent alterations of the gut microbiota, allowing it to maintain immune homeostasis. Stress situations and infections may trigger autoimmune responses. Cancer may foster the development of autoimmune manifestations, and these, due to the inflammatory predominance, may foster tumorigenesis(AU)

ABSTRACT

RESUMEN El lupus eritematoso sistémico (LES) es una enfermedad autoinmune que afecta múltiples órganos; el compromiso renal se encuentra en el 50% de los pacientes y es variable de acuerdo con el grupo racial y étnico. Se estima que el 10% de los pacientes con nefritis lúpica (NL) desarrollan enfermedad renal terminal (ERT) y, una vez que se da la progresión, el 80% de los pacientes negativizan los marcadores de actividad. Sin embargo, aunque es inusual, la reactivación de la enfermedad puede presentarse en compromiso renal avanzado y es importante diagnosticarla oportunamente para definir la causa, tratarla y evitar complicaciones. Presentamos el caso clínico de una paciente de 45 arios, con ERT en diálisis peritoneal, que se encontraba en remisión de la enfermedad y posteriormente desarrolló actividad lúpica.


ABSTRACT Systemic lupus erythematosus (SLE) is an autoimmune disease that affects multiple organs, and renal involvement is found in 50% of patients and is variable according to racial and ethnic group. It is estimated that 10% of patients with lupus nephritis (NL) develop end-stage renal disease (ERT), and once progression occurs, 80% of patients are negative for activity markers. However, although it is rare, the reactivation of the disease can occur in advanced renal involvement, and it is important to diagnose it in a timely manner to define the cause and treat it, avoiding complications.

ABSTRACT

Si bien las enfermedades ampollares autoinmunes son infrecuentes en la infancia y la juventud, es importante tenerlas en cuenta dentro del diagnóstico diferencial, junto con otras enfermedades inflamatorias o infecciosas de mayor prevalencia, para lograr un diagnóstico temprano y así indicar el tratamiento preciso y oportuno. El pénfigo foliáceo es una enfermedad ampollar poco común, salvo en la zona endémica de Brasil. Se presenta un caso de pénfigo foliáceo con eritrodermia como cuadro clínico con mala evolución (AU)


Although autoimmune bullous diseases are infrequent in childhood and youth, it is important to take them into account within the differential diagnosis, along with other more prevalent inflammatory or infectious diseases, to achieve an early diagnosis and thus indicate precise and timely treatment. Pemphigus foliaceus is a rare autoimmune bullous diseases, except in the endemic area of Brazil. This case report presents a patient with the unusual erythrodermic presentation of pemphigus with poor evolution (AU)

ABSTRACT

IPAF agrupa individuos con EPID y otras características clínicas, serológicas o pulmonares que derivan de una condición autoinmune sistémica subyacente, pero no cumplen con los criterios reumatológicos actuales para una ETC. La EPID, manifestación clínica frecuente de las ETC, puede aparecer en el contexto de una ETC conocida pero no es infrecuente que sea la primera y única manifestación de un ETC oculta. Identificar una ETC subyacente en pacientes que presentan con compromiso intersticial inicial puede ser un desafío; tales evaluaciones pueden optimizarse mediante un enfoque multidisciplinario. Presentamos el caso de tres pacientes, de diferente presentación, evolución y tratamiento, todos caracterizados hasta la fecha como IPAF.


IPAF groups individuals with ILD and other clinical, serologic, or pulmonary manifestations with an underlying systemic autoimmune condition, but do not meet current rheumatologic criteria for a CTD. ILD is a frequent clinical manifestation of CTDs; may appear in the context of a well known CTD but is often the first and only manifestation of an unknown CTD. Identifying an underlying CTD in patients presenting with initial interstitial involvement can be challenging; such evaluations can be optimized using a multidisciplinary approach. We present the case of three patients, of different presentation, evolution and treatment, all characterized to date as IPAF.

ABSTRACT

ABSTRACT Objective: to learn the perception of individuals with Systemic Lupus Erythematosus about living with the disease. Method: an exploratory and descriptive research study, of a qualitative nature, carried out with 26 individuals undergoing treatment at the rheumatology outpatient clinic of a university hospital in southern Brazil. The data were collected in the period from February to July 2019, by means of semi-structured interviews that were audio-recorded and subjected to the thematic modality of content analysis. Results: a category entitled: "Fluctuating between good and bad days in living with Systemic Lupus Erythematosus", composed of two subcategories that portray that living with Lupus is something unstable/fickle, emerged from the results. This is because, as a result of the periods of remission and exacerbation of the signs and symptoms of the disease, the patients experience a paradox of constant oscillation between ups and downs. Conclusion: it was learned that individuals with Lupus perceive that living with the disease is marked by an oscillation between good days and bad days, which are related to periods of remission and exacerbation of the manifestations of the disease, respectively.


RESUMEN Objetivo: averiguar de qué manera las personas con Lupus Eritematoso Sistémico perciben su convivencia con la enfermedad. Método: investigación descriptiva y exploratoria, de naturaleza cualitativa, realizada con 26 individuos en tratamiento en la clínica ambulatoria de reumatología de un hospital universitario del sur de Brasil. Los datos se recolectaron durante el período de febrero a julio de 2019, mediante entrevistas semiestructuradas, grabadas en audio y sometidas a análisis de contenido, en su modalidad temática. Resultados: de los datos surgió una categoría temática de título: "Oscilando entre días buenos y malos en la vida diaria con Lupus eritematoso sistémico", compuesta por dos subcategorías, que indican que vivir con Lupus es algo inestable/voluble. Esto se debe a que, a raíz de los períodos de remisión y exacerbación de las señales y los síntomas de la enfermedad, se experimenta la paradoja de una oscilación constante entre buenos y malos momentos. Conclusión: se descubrió que las personas con Lupus perciben que la convivencia con la enfermedad está marcada por una oscilación entre días buenos y días malos, que están relacionados, respectivamente, con los períodos de remisión y exacerbación de las manifestaciones de la enfermedad.


RESUMO Objetivo: apreender a percepção de indivíduos com Lúpus Eritematoso Sistêmico sobre a convivência com a doença. Método: pesquisa descritiva exploratória, de natureza qualitativa, realizada junto a 26 indivíduos em tratamento no ambulatório de reumatologia de um hospital universitário do Sul do Brasil. Os dados foram coletados no período de fevereiro a julho de 2019, mediante entrevistas semiestruturadas, audiogravadas e submetidas à análise de conteúdo, modalidade temática. Resultados: dos dados emergiu uma categoria temática intitulada: "Oscilando entre dias bons e ruins na convivência cotidiana com o Lúpus Eritematoso Sistêmico", composta por duas subcategorias, as quais retratam que conviver com Lúpus é algo instável/inconstante. Isto porque, em decorrência dos períodos de remissão e exacerbação dos sinais e sintomas da doença, vivencia-se o paradoxo de uma constante oscilação entre altos e baixos. Conclusão: apreendeu-se que os indivíduos com Lúpus percebem que a convivência com a doença é marcada por uma oscilação entre dias bons e dias ruins, os quais estão respectivamente, relacionados aos períodos de remissão e exacerbação das manifestações da doença.

ABSTRACT

The etiology of subacute combined degeneration (SCD) of the spinal cord is closely associated with vitamin B12 (VitB12) deficiency. The clinical manifestations of SCD are complex and vary substantially. Due to some SCD patients with atypical manifestations and concomitant autoimmune disorders, the probability of misdiagnosis and missed diagnosis is still relatively high in the early stage. We report the cases of two patients who were missed or misdiagnosed at another hospital because of the normal initial VitB12 level and partial overlap of clinical manifestations, finally diagnosed as SCD with atypical manifestations and concomitant autoimmune disorders, pharyngeal-cervical-brachial Guillain-Barre syndrome in Case 1 and SCD with autoimmune thyroiditis in Case 2. After undergoing corresponding treatment, death was reported in Case 1 and improvement in Case 2. Analysis of the clinical manifestations and investigation of the underlying pathogenesis in such patients could help improve the rate of early diagnosis and allow timely treatment of SCD, thereby preventing disease progression and poor clinical outcomes.

ABSTRACT

Circular RNA (circRNA) is a novel class of single-stranded RNAs with a closed loop structure. The majority of circRNAs are formed by a back-splicing process in pre-mRNA splicing. Their expression is dynamically regulated and shows spatiotemporal patterns among cell types, tissues and developmental stages. CircRNAs have important biological functions in many physiological processes, and their aberrant expression is implicated in many human diseases. Due to their high stability, circRNAs are becoming promising biomarkers in many human diseases, such as cardiovascular diseases, autoimmune diseases and human cancers. In this review, we focus on the translational potential of using human blood circRNAs as liquid biopsy biomarkers for human diseases. We highlight their abundant expression, essential biological functions and significant correlations to human diseases in various components of peripheral blood, including whole blood, blood cells and extracellular vesicles. In addition, we summarize the current knowledge of blood circRNA biomarkers for disease diagnosis or prognosis.

ABSTRACT

Neutrophil extracellular traps(NETs) are networks of extracellular fibers primarily composed of DNA, histones, granular proteins, and cytoplasmic proteins and released to the outside of cells by neutrophils under the stimulation of bacteria, fungi, viruses, parasites, etc. NETs are generated in two forms, suicidal NETs and vital NETs, according to different stimuli. NETs have both anti-inflammatory and pro-inflammatory effects. On the one hand, they can play the anti-microbial role to resist inflammation by capturing, fixing, and killing invading pathogens, which is a special way for neutrophils to exert host defenses. On the other hand, in case of excessive formation or insufficient elimination, they can cause tissue damage directly, and also promote the release of inflammatory factors by recruiting other pro-inflammatory cells or proteins to further expand the inflammatory response, which is related to the pathologies of many diseases. In autoimmune diseases, NETs as important sources of autoantigens, can act as danger-associated molecular patterns( DAMPs) and activate the nucleotide-binding oligomerization domain leucine-rich repeats containing pyrin domain 3(NLRP3) inflammasome and complement system, thereby breaking self-tolerance and accelerating autoimmune inflammation. In addition, NETs can also activate other immune cells(such as B cells, antigen-presenting cells, and T cells) and regulate the acquired immune response. The present study reviewed the correlation of NETs with diseases such as systemic lupus erythematosus(SLE), rheumatoid arthritis(RA), and gouty arthritis(GA) to reveal the effect of dynamic balance between formation and clearance of NETs in autoimmune diseases and provide a theoretical basis for the investigation of underlying mechanisms and targeted therapies of traditional Chinese medicine.

ABSTRACT

Rhei Radix et Rhizoma was first recorded in Shennong Ben Cao Jing, with a wide range of pharmacological activities. Autoimmune disease is a kind of disease that damages the tissue structure and function of immune cells and their components due to the impairment of immune tolerance function, including atherosclerosis, multiple sclerosis, gout, rheumatoid arthritis, autoimmune thyroiditis, ulcerative colitis, type 1 diabetes and IgA nephropathy. In recent years, clinical and experimental studies show that Rhei Radix et Rhizoma has potential therapeutic effects on autoimmune diseases. Under the guidance of the theory of traditional Chinese medicine, this paper reviews therapeutic and intervening effects of Rhei Radix et Rhizoma and its main active ingredient anthraquinone on autoimmune diseases. It also puts forward new study directions in view of the existing problems in studies of rhubarb and its anthraquinone, with the aim to provide reference for clinical treatment and scientific studies of effect of Rhei Radix et Rhizomaon autoimmune diseases.

ABSTRACT

Oral lichen planus (OLP) is a chronic inflammatory oral mucosal disease with unclear etiology. Autoimmune thyroid diseases (AITD) is a type of autoimmune disease characterized by increased thyroid-specific antibodies. In recent years, more and more studies have found that the incidence of AITD is increased in OLP patients. The occurrence and development of OLP and AITD may be related to the expression of thyroid autoantigen in oral keratinocytes, the imbalance of thyroid hormone (Th)1/Th2 and Th17/Treg cell subsets, the abnormal quantity and function of follicular helper T cells and chemokines and the specific killing ability of CD8 T cells to target cells. In this article, the possible immune mechanisms involved in the coexistence of OLP and AITD are reviewed to provide insights for the diagnosis, treatment and prevention of these two diseases from the perspective of immunology.

ABSTRACT

ABSTRACT Background: Systemic sclerosis is an autoimmune and multisystemic disease characterized by vascular involvement and fibrosis that mainly affects the skin and internal organs; its morbidity and mortality are the highest of rheumatic diseases. Objective: To determine the sociodemographic, clinical, and paraclinical characteristics of adult patients with systemic sclerosis in a reference center in rheumatology in northwestern Colombia, between 2006 and 2016. Methods: A retrospective descriptive study was conducted. Information on sociodemographic, clinical, and paraclinical variables was collected from the review of medical records. The data were processed with the IBM SPSS 22 statistical package. The qualitative variables were expressed in absolute and relative frequencies and the quantitative variables in mean and standard deviation or median and interquartile range, according to their distribution. Results: 44 patients were included, predominantly women (90.9%), with an average age of 59 years; the most common variety was the limited (61.3%). One hundred percent of the subjects presented Raynaud's phenomenon and the most common compromised systems were: cutaneous (100%), musculoskeletal (59.1%), and gastrointestinal (50%). 95.5% of the patients fulfilled the diagnostic criteria ACR / EULAR 2013. Regarding the immunological profile, 72.7% of the individuals had positive antinuclear antibodies, of which 53.1% had a centromeric pattern. Conclusions: Sociodemographic, clinical and similar characteristics were found in this cohort, according to what was published in the literature. The most frequent extracutaneous systems involved were: musculoskeletal, gastrointestinal, and pulmonary, which cause a large part of the associated morbidity, as well as a decrease in quality of life.


RESUMEN Introducción: La esclerosis sistémica es una enfermedad autoinmune y multisistémica, caracterizada por vasculopatía y fibrosis que afecta principalmente la piel y órganos internos; su morbilidad y mortalidad son las más altas de las enfermedades reumatológicas. Objetivo: Determinar las características sociodemográficas, clínicas y paraclínicas de pacientes adultos con esclerosis sistémica en un centro de referencia en reumatología del noroccidente de Colombia, entre el 2006 y el 2016. Métodos: Estudio descriptivo retrospectivo. La información sobre las variables sociodemográficas, clínicas y paraclínicas se recogió de la revisión de registros médicos. Los datos se procesaron con el paquete estadístico IBM SPSS 22. Las variables cualitativas se expresaron en frecuencias absolutas y relativas y las cuantitativas en media y desviación estándar o mediana y rango intercuartílico, según su distribución. Resultados: Se incluyeron 44 pacientes, predominantemente mujeres (90,9%), con una edad promedio de 59 arios; la variedad más común fue la limitada (61,3%). El 100% de los sujetos presentaron el fenómeno de Raynaud y los sistemas comprometidos con mayor frecuencia fueron: cutáneo (100%), musculoesquelético (59,1%) y gastrointestinal (50%). El 95,5% de los pacientes cumplieron con los criterios diagnósticos ACR/EULAR 2013. Con respecto al perfil inmunológico, el 72,7% de los individuos tenía anticuerpos antinucleares positivos, de los cuales, un 53,1% tenía un patrón centromérico. Conclusiones: Se encontraron características sociodemográficas y clínicas similares en esta cohorte, de acuerdo a lo publicado en la literatura. Los sistemas extracutáneos más frecuentemente involucrados fueron: musculoesquelético, gastrointestinal y pulmonar, que causan una gran parte de la morbilidad asociada, así como una disminución en la calidad de vida.

ABSTRACT

ABSTRACT Systemic sclerosis (SSc) is a systemic autoimmune disease in which gastrointestinal manifestations are a frequent complication. Gastrointestinal involvement is present in up to 90 % of patients. The most affected areas are the esophagus and the anorectal tract. Reflux, heartburn and dysmotility are the leading causes of gastrointestinal discomfort. Disordered anorectal function can occur early in the course of SSc and is an important factor in the development of fecal incontinence. Current recommendations to treat gastrointestinal disorders in SSc include the use of proton pump inhibitors, prokinetics and rotating antibiotics. This review discusses the proposed pathophysiological mechanisms, the clinical presentation, the different diagnostic techniques and the current management of the involvement of each section of the gastrointestinal tract in SSc.


RESUMEN La esclerosis sistémica (ES) es una enfermedad autoinmune sistémica en la que las manifestaciones gastrointestinales son una complicación frecuente. El compromiso gastrointestinal está presente hasta en 90% de los pacientes. Las áreas más afectadas son el esófago y el tracto anorrectal. El reflujo, la pirosis y la dismotilidad son las principales causas de malestar gastrointestinal. La función anorrectal alterada puede presentarse temprano en el curso de la ES y es un factor importante en el desarrollo de incontinencia fecal. Las recomendaciones actuales para tratar los trastornos gastrointestinales en la ES incluyen el uso de inhibidores de la bomba de protones, procinéticos y de antibióticos en forma rotativa. Esta revisión discute los mecanismos fisiopatológicos propuestos, la presentación clínica, las diferentes técnicas de diagnóstico y el manejo actual del compromiso de cada sección del tracto gastrointestinal en la ES.

ABSTRACT

ABSTRACT Mounting evidence has shown non-systemic sclerosis (SSc) related complications as a rising cause of hospital admission and mortality, out of which infections are among the top-five causes. Patients with SSc are at an increased risk of infection due to several features of the treatment options and to the disease itself. For instance, lung involvement is associated with a higher frequency of respiratory infections, whereas the presence of digital ulcers or calcinosis may result in skin and soft tissue infections, and even osteomyelitis. On the other hand, the growing trend towards immunomodulation and immunosuppression in patients with autoimmune diseases will place SSc patients at a higher risk of infectious complications, including opportunistic infections. A low suspicion threshold and an increasing awareness among treating specialists, particularly rheumatologists, are warranted for prevention, early diagnosis and management of infectious complications. Nonetheless, data on risk management strategies in SSc, such as vaccination and antimicrobial prophylaxis, are scarce. A narrative non-systematic review was performed to provide an update of infectious complications in patients with SSc.


RESUMEN La evidencia creciente muestra que las complicaciones no asociadas a la esclerosis sistémica (ES) son una causa cada vez más frecuente de hospitalización y mortalidad, dentro de las cuales las infecciones se encuentran entre las primeras cinco causas. Los pacientes con ES presentan un riesgo elevado de infección asociado con las opciones terapéuticas y con la enfermedad misma. Por ejemplo, el compromiso pulmonar se asocia con una mayor frecuencia de infecciones respiratorias, mientras que la presencia de úlceras digitales o calcinosis pueden resultar en infecciones de piel y tejidos blandos, incluso en osteomielitis. Por otro lado, la tendencia creciente hacia la inmunomodulación y la inmunosupresión, como tratamiento de las enfermedades autoinmunes, pondrá a estos pacientes en un mayor riesgo de infecciones, incluidas las infecciones oportunistas. Son necesarios un umbral bajo de sospecha y un alto nivel de alerta entre las especialidades tratantes, particularmente los reumatólogos, para la prevención, el diagnóstico temprano y el manejo de las complicaciones infecciosas. Sin embargo, la información respecto a estrategias de gestión de riesgo en ES, como la vacunación o la profilaxis antibiótica, es escasa. Se realizó una revisión narrativa no sistemática que presenta una actualización sobre las complicaciones infecciosas en pacientes con ES.

ABSTRACT

Al igual que en las enfermedades autoinmunes y reumáticas, las infecciones por virus pueden ser disparadores de mecanismos inmunopatogénicos. El SARSCoV-2 puede causar la liberación de citocinas y provocar un daño tisular grave, sobre todo pulmonar, con peligro para la vida. Se suma a ello el riesgo del uso de medicamentos inmunosupresores, empleados en los protocolos de tratamiento de las afecciones autoinmunes y también contra la infección viral de COVID-19. Hoy no contamos con conocimientos y evidencias científicas suficientemente sólidas para el enfrentamiento a la COVID-19, y cómo puede impactar entre los pacientes inmunodeprimidos por afecciones reumáticas. El Grupo Nacional de Atención y Enfrentamiento a la COVID-19 de la Sociedad Cubana de Reumatología se propuso elaborar un documento científico actualizado con las bases teórico-prácticas que permita acceder al conocimiento acerca de la infección por SARSCoV-2 y la COVID-19, y su repercusión sobre los pacientes con enfermedades autoinmunes y reumáticas para esbozar una estrategia de trabajo y ofrecer recomendaciones para los reumatólogos y pacientes cubanos. Se realizó un estudio de revisión y actualización acerca de la asociación entre las enfermedades reumáticas y autoinmunes y la COVID-19. Se emplearon las palabras clave enfermedades reumáticas, lupus eritematoso sistémico, artritis reumatoide, virus SARSCoV-2 y COVID-19. Se realizó una amplia búsqueda en MEDLINE y LILACS, y se revisaron más de 150 artículos, boletines de actualización de los sitios Web, páginas de salud de Cuba, resúmenes seleccionados por su calidad metodológica, revisiones y metaanálisis sobre el tema. A partir de la información recogida, se estableció una discusión y análisis considerando las principales experiencias internacionales, criterios de expertos, experiencias previas con otros virus en el Sistema de Salud de Cuba, con la participación de su red de científicos liderados por la Sociedad Cubana de Reumatología y su Grupo Nacional y el apoyo de la comunidad de reumatólogos(AU)


The outbreak of the infection by the new coronavirus SARSCoV-2, COVID-19, in December in Wuhan Province of China, has become a pandemic and health emergency given the deficiency of antiviral therapy for the acute respiratory syndrome that generates danger to life. The debut of the epidemic was in China, then the epicenter developed in Europe, northern Italy that suffered a severe blow. Worldwide, more than 10 million people are infected with the virus that has impacted on health systems until it practically collapsed, resulting in thousands of deaths. Today the epicenter of the pandemic has shifted to the Americas. Alarming figures highlight the United States of North America with some 2,737,600 infected and more than 128,471 deaths, followed by the South American giant Brazil with 1.3 million infections and 57,659 deaths. The Caribbean has a better setting. In Cuba, by the end of June, 2,340 cases of patients infected with deaths from COVID-19 were reported. We conducted a review, analysis and evaluation study of more than 150 articles from international journals, update bulletins of the WEB sites, health pages of the MINSAP of Cuba, and summaries selected for their methodological quality, and reviews, on the subject COVID-19 and autoimmune-rheumatic diseases by MEDLINE: database prepared by the National Library of Medicine of The USA contains bibliographic references and abstracts from more than 4,000 biomedical journals published in the United States and in 70 other countries, We also use Latin American and Caribbean Center for Information on Health Sciences: System, in Latin America and the Caribbean, since 1982. Our objective and results achieved have been to develop the theoretical-practical bases in an updated scientific document that allow access in an essential and summarized way to current knowledge about the infection by SACOV-2, COVID-19, and its repercussion and impact on patients suffering from rheumatic autoimmune diseases, and thus outline a coping and action strategy with recommendations for the Cuban rheumatologists in their health care work, and for patients as a guideline, given their well-founded concerns and fears given their underlying condition and the immunosuppressive drugs prescribed in an unfavorable context of a pandemic. The information is based on international experiences with the most published scientific evidence and those treasured national experiences in the face of similar situations of epidemics, faced by the vast health system and achievements of Cuban science(AU)

ABSTRACT

La neumonía intersticial con características autoinmunes por sus siglas en inglés, es una entidad en la que existe un compromiso pulmonar intersticial y hallazgos clínicos y paraclínicos que sugieren una enfermedad del tejido conectivo, aunque no cumplen criterios diagnósticos para ninguna de estas. Con fines de investigación, en el 2015 se describieron criterios para esta entidad, en los que se incluyeron características de los dominios clínicos, serológicos y morfológicos, con diversos patrones de compromiso pulmonar. En la actualidad, hay un aumento en el interés de esta entidad, pues algunos autores sugieren que se pueda tratar de una enfermedad autoinmune per se, cuyo órgano blanco principal sería el pulmón. Dado su reciente reconocimiento, son pocos los casos descritos en la literatura. Con el propósito de contribuir a la mejor identificación de esa entidad, presentamos el caso de una paciente de 68 años con afectación pulmonar en quien después de descartar otras causas se llegó al diagnóstico de neumonía intersticial con características autoinmunes al cumplir los criterios de cada dominio requerido. Se inició tratamiento con micofenolato mofetilo a dosis de 2,5 mg/día. En su evolución clínica, la paciente presentó mejoría y fue dada de alta con tratamiento ambulatorio(AU)


Interstitial pneumonia with autoimmune features is a condition in which patients can have clinical and serological findings suggesting of a connective tissue disease associated with an interstitial lung disease, nonetheless no criteria for an specific connective tissue disease are meeting. In 2015 classification criteria where proposed, the diagnosis is made in the presence of a combination of features from clinical, serological and morphological domain with various patterns of pulmonary involvement. Currently there is an increase in the interest of this condition, as some authors suggest that it can be an autoimmune pathology per se, whose main target organ would be the lung. Given its recent recognition, there are few cases described in the literature and therefore in order to contribute to the better identification of that entity, we present the case of a 65 year old patient with lung involvement in whom after ruling out other etiological causes reached the diagnosis of I Interstitial pneumonia with autoimmune by meeting criteria of each required domain(AU)
