ABSTRACT

ABSTRACT BACKGROUND: Immunosuppressive drugs have important role in transplant of solid grafts, it aim avoid episodes of acute and chronic rejection and improving graft survival and patient survival. In Brazil, in 2016, liver transplantation was the third most frequent, with 1,880 transplants performed, of which 150 in Rio Grande do Sul. Several studies evaluated the association between variability in blood levels of immunosuppressive tacrolimus and late acute cellular graft rejection. OBJECTIVE: To investigate the association of tacrolimus blood levels with clinical outcomes late acute cellular rejection, death, patient survival and graft survival in patients undergoing liver transplantation. METHODS: This is a retrospective longitudinal study including patients submitted to adult liver transplantation by the Liver Transplantation Group in the Santa Casa de Misericórdia Hospital of Porto Alegre, from January 2006 to January 2013, and who used tacrolimus as immunosuppressive therapy. RESULTS: Of the 127 patients included in the study, the majority were male (70.1%), 52-60 years old (33.9%) at the transplant. The most frequent causes of liver transplantation in this series were hepatitis C virus and hepatocellular carcinoma (24.4%) and alcohol (15.7%). Thirteen patients had late acute cellular rejection (10.2%); of these, three had two episodes. Regarding severity classification, seven patients had mild late acute cellular rejection. The mean time of rejection after liver transplantation was 14 months (ranging from 8 to 33 months). Overall survival was 8.98 years. Regarding tacrolimus blood levels, 52 patients with a variation ≥2 standard deviations were identified. Of these patients, eight had rejection; however, the association was not significant (P=0.146). A significant association was found between variation ≥2 standard deviations in tacrolimus blood levels and death (P=0.023) and survival (P=0.019). Regarding 5-year follow-up of graft survival, being two standard deviations above increases by 2.26 times the risk of transplanted graft loss, and for each unit of increase of standard deviation of tacrolimus blood levels there is a two-fold increase in the risk of graft loss in 5 years. CONCLUSION: Increased risk of graft loss associated with increased standard deviations of tacrolimus blood levels may indicate the need for more rigorous and prospective monitoring of tacrolimus blood levels.


RESUMO CONTEXTO: Os imunossupressores desempenham importante papel no transplante de órgãos sólidos, com o objetivo de evitar a rejeição aguda e crônica, aumentando o tempo de sobrevida do órgão e do paciente. No Brasil, em 2016, o transplante de fígado foi o 3° mais frequente, com um número de 1.880 transplantes, sendo 150 realizados no Rio Grande do Sul. OBJETIVO: Investigar a associação da variação dos níveis sanguíneos de tacrolimo com os desfechos clínicos, rejeição celular aguda tardia, óbito, sobrevida de paciente e enxerto em pacientes submetidos ao transplante hepático. MÉTODOS: Trata-se de um estudo longitudinal retrospectivo, no qual foram incluídos os pacientes submetidos ao transplante hepático adulto pelo grupo de transplante hepático na Irmandade Santa Casa de Misericórdia de Porto Alegre, no período de janeiro de 2006 a janeiro de 2013, e que fizeram o uso de tacrolimo como terapia imunossupressora. RESULTADOS: Dos 127 pacientes incluídos no estudo, a maioria era do gênero masculino (70,1%), caucasiana (86,4%), com idade entre 52 e 60 anos (33,9%). As associações de causas mais frequentes para transplante hepático foram vírus da hepatite C, carcinoma hepatocelular (24,4%) e álcool (15,7%). Um total de treze pacientes apresentaram rejeição celular aguda tardia (10,2%); destes, três tiveram dois episódios. O tempo médio de rejeição após o transplante hepático foi de 14 meses, variando de 8 a 33 meses. A sobrevida global foi de 8,98 anos. Em relação aos níveis sanguíneos de tacrolimo, foram identificados 52 pacientes com uma variação maior ou igual a dois desvios-padrão. Destes pacientes, oito tiveram rejeição, contudo, a associação não foi significativa (P=0,146). Foi encontrada uma associação significativa entre a variação maior ou igual a dois desvios-padrão nos níveis sanguíneos de tacrolimo com óbito (P=0,023) e sobrevida (P=0,019). Em relação ao acompanhamento de sobrevida do enxerto em cinco anos, estar dois desvios-padrão acima aumenta em 2,26 vezes o risco de perda do enxerto transplantado, e a cada unidade de aumento de desvio-padrão dos níveis sanguíneos de tacrolimo há um aumento de duas vezes no risco de perda do enxerto transplantado em 5 anos. CONCLUSÃO: O aumento do risco da perda do enxerto associado ao aumento da variação dos níveis sanguíneos de tacrolimo pode indicar a necessidade do acompanhamento mais rigoroso e prospectivo dos níveis sanguíneos de tacrolimo.

ABSTRACT

Idiopathic retroperitoneal fibrosis is a rare fibro-inflammatory disease of varied etiology which usually originates around aorta and spreads caudally along Iliac vessels into adjacent retroperitoneum causing ureteral obstruction as the most frequent complication.A 53-year-old male patient presented with complaint of mild pain in both the legs off and on. On investigating further, we found that he had been struggling with intermittent relapses every 3-4 years for last 20 years since he was first diagnosed with Idiopathic Retroperitoneal Fibrosis. He was 33-year-old when he first developed the symptoms of anuria for 48 hours and was diagnosed with Idiopathic retroperitoneal fibrosis. This was followed by atrophy of left kidney and hypertension 6 years later, then hypothyroidism after another 3years and finally involvement of Inferior Vena Cava and acute Deep Vein Thrombosis of lower limbs after another 3-4 years. His deep vein thrombosis was well managed in time. He was put on glucocorticoids everytime he had a relapse and a complication.We did a review of literature to understand recent advances about its pathogenesis, diagnosis, investigations and management. We searched in PubMed using terms like retroperitoneal fibrosis alone and in combination with related terms such as Inferior Vena Cava thrombosis, Deep Vein Thrombosis, Tamoxifen, Methotrexate. This case is unique as it is very rare to find acute Deep Vein Thrombosis in Idiopathic retroperitoneal fibrosis without development of any collaterals when Inferior Vena Cava lumen is compromised to almost complete obstruction.After a follow up of 20 years patient is doing well in terms of physical activity and psychological wellbeing with anti-hypertensives, thyroxine and anti-coagulants. Is the disease-free interval actually free of the disease or it just subsided with immunosuppressants to become active after some time?


La fibrosis retroperitoneal idiopática es una enfermedad fibroinflamatoria rara, de etiología variada que generalmente se origina alrededor de la aorta y se propaga caudalmente a lo largo de los vasos ilíacos en retroperitoneo adyacente causando obstrucción ureteral como la complicación más frecuente.Reportamos el caso de un paciente varón de 53 años que se presentó con un dolor leve en ambas piernas. Al investigar más a fondo, descubrimos que había estado luchando con recaídas intermitentes cada 3-4 años durante los últimos 20 años desde que se le diagnosticó por primera vez fibrosis retroperitoneal idiopática. Tenía 33 años cuando desarrolló por primera vez los síntomas de anuria durante 48 horas y se le diagnosticó fibrosis retroperitoneal idiopática. Esto fue seguido por atrofia del riñón izquierdo e hipertensión 6 años después, luego hipotiroidismo después de otros 3 años y finalmente afectación de la vena cava inferior y trombosis venosa profunda aguda de las extremidades inferiores después de otros 3-4 años. Su trombosis venosa profunda se controló bien a tiempo. Le recetaron glucocorticoides cada vez que tenía una recaída y una complicación.Hicimos una revisión de la literatura para comprender los avances recientes sobre su patogenia, diagnóstico, investigaciones y manejo. Se realizaron búsquedas en PubMed utilizando términos como fibrosis retroperitoneal sola y en combinación con términos relacionados como trombosis de la vena cava inferior, trombosis venosa profunda, tamoxifeno, metotrexato. Este caso es único, ya que es muy raro encontrar trombosis venosa profunda aguda en fibrosis retroperitoneal idiopática sin desarrollo de colaterales cuando la luz de la vena cava inferior está comprometida hasta una obstrucción casi completa.Después de un seguimiento de 20 años, el paciente se encuentra bien en términos de actividad física y bienestar psicológico con antihipertensivos, tiroxina y anticoagulantes. ¿El intervalo libre de enfermedad está realmente libre de la enfermedad o simplemente disminuyó con inmunosupresores para activarse después de algún tiempo?

ABSTRACT

This study aimed to identify, by means of thromboelastometry assessment, altered thrombotic risk in dogs with primary and secondary IMHA by E. canis infection after initiating the immunosuppressive therapy with mycophenolate mofetil. The animals' screening was based on complete blood count (CBC), biochemical and urine tests. Dogs with moderate to severe anemia (hematocrit ≤ 25%) which showed symptoms of immune-mediated hemolysis, such as spherocytosis, positive saline agglutination, bilirubinuria and/or hemoglobinuria, were included. Blood and urine samples were collected at two different moments. The first sample (M1) was collected at the time of diagnosis, when hematocrit was lower or equal to 25% before treatment with mycophenolate mofetil (Accord ®); the second sample (M2) was collected after treatment with mycophenolate mofetil, when hematocrit was greater or equal to 30%. Five out of the twelve animals selected died before the end of the study. No reduction in thrombotic risk was observed in the animals treated with mycophenolate mofetil. The animals that presented hypocoagulation at the time of diagnosis showed the worst prognosis, and their reticulocyte count displayed a better prognostic value than their erythrocytes count at the time of diagnosis.(AU)


O objetivo deste estudo foi esclarecer se há alteração do risco trombótico em cães com anemia hemolítica imunomediada primária e secundária a E.canis, avaliado por meio da tromboelastometria, após início de tratamento com micofenolato de mofetila. A seleção dos animais foi baseada na avaliação de hemograma, exame bioquímico e urinálise. Cães com anemia moderada a severa (hematócrito ≤ 25%), com sinais de hemólise imunomediada, como esferocitose, aglutinação em salina positivo, bilirrubinúria e/ ou hemoglobinúria, foram incluídos. As amostras de sangue e urina foram coletadas em dois momentos diferentes. A primeira amostra (M1) foi coletada no momento do diagnóstico, quando o hematócrito era igual ou inferior a 25%, sem fazer uso do micofenolato de mofetila (Accord®), e o segundo momento (M2), após tratamento com micofenolato de mofetila, quando o hematócrito era igual ou maior que 30%. Doze animais foram selecionados, cinco morreram antes do término do estudo. Não houve diminuição do risco trombótico entre os animais tratados com micofenolato de mofetila; os animais que apresentaram menor coagulabilidade apresentaram pior prognóstico, e a contagem de reticulócitos apresentou melhor valor prognóstico do que a contagem de hemácias no momento do diagnóstico.(AU)

ABSTRACT

ABSTRACT A 45-year-old female patient presented with a complaint of right eye redness and pain for 7 days. She was under investigation for urinary abnormalities and reported a previous history of recurrent oral ulcers and ocular hyperemia in both eyes. Best-corrected visual acuity was 20/30 and 20/20 in the right and left eyes, respectively. Slit-lamp biomicroscopy of the ocular surface of the right eye revealed nasal scleral hyperemia that persisted after instillation of topical phenylephrine 10%, reinforcing the diagnosis of anterior scleritis. Renal biopsy showed immunoglobulin A immune complexes and confirmed the suspected diagnosis of Berger's disease. Maintenance immunosuppressive therapy with azathioprine following a 6-month induction of remission with cyclophosphamide was necessary after pulse therapy with methylprednisolone. Scleritis is usually related to systemic autoimmune diseases, such as rheumatoid arthritis, and polyangiitis. Herein, we describe a rare case of unilateral anterior scleritis associated with Berger's disease.


RESUMO Paciente de 45 anos, sexo feminino queixava-se de hiperemia e dor no olho direito há sete dias. Encontrava-se sob investigação de alterações urinárias e relatou história pregressa de úlceras orais e hiperemia ocular bilateral recorrentes. A acuidade visual corrigida era de 20/30 no olho direito e 20/20 no esquerdo. A biomicroscopia da superfície ocular do olho direito revelou intensa hiperemia escleral em região nasal que persistiu após a instilação de fenilefrina tópica a 10%, reforçando o diagnóstico clínico de esclerite anterior unilateral. A biópsia renal revelou a presença de imunocomplexos de IgA e confirmou a hipótese de doença de Berger. Uma terapia imunossupressora de manutenção com azatioprina após 6 meses de indução de remissão com ciclofosfamida foi necessária após pulsoterapia com metilprednisolona. A esclerite geralmente está relacionada a doenças autoimunes sistêmicas, como artrite reumatoide e poliangeite. Descrevemos aqui um caso raro de esclerite anterior unilateral associada à doença de Berger.

ABSTRACT

ABSTRACT OBJECTIVE To estimate the prevalence and variability of nonadherence to immunosuppressives and nonpharmacological treatment across kidney transplantation centers and two health access-disparate regions in Brazil. METHODS In a cross-sectional design, a random multistage sample of 1,105 patients was included, based on center transplantation activity (low/moderate/high) and region (R1: North/Northeast/Mid-West; and R2: South/Southeast). Nonadherence to immunosuppressives (implementation phase) was assessed using the Basel Assessment of Adherence to Immunosuppressive Medications Scale (BAASIS)©. Self-report questionnaires assessed nonadherence to physical activity, smoking cessation, alcohol intake, and appointment keeping. We compared regions using the adjusted-χ2 or t-test. RESULTS Most patients were men (58.5%), white (51.4%), and had a mean age of 47.5 (SD = 12.6) years. Regarding kidney transplantation centers, 75.9% were from R2 and 38.2% had low activity. The patients in R2 were older, white-majority, had more frequently steady partners, and received peritoneal dialysis. Nonadherence to immunosuppressives ranged from 11-65.2%; 44.5-90% to physical activity; 0-23.7% to appointment keeping; and 0-14% to smoking cessation. The total prevalence of nonadherence and by region (R1 versus R2) were: for immunosuppressives, 39.7% (44.9% versus 38.1%, p = 0.18); for smoking, 3.9% (1% versus 5%, p < 0.001); for physical activity, 69.1% (71% versus 69%, p = 0.48); for appointment keeping, 13% (12.7% versus 12%, p = 0.77); and for alcohol consumption, 0%. CONCLUSION Despite differences among centers and high variability, only the nonadherence to smoking cessation was higher in the region with greater access to kidney transplantation. We suppose that differences in healthcare access may have been overcome by other positive aspects of the post kidney transplantation treatment.

ABSTRACT

Tacrolimus (TAC), a calcineurin inhibitor, and everolimus (EVL), an mTOR inhibitor, have been used as immunosuppressive (ISS) drugs in post-kidney transplantation therapy. The objective of this study was to compare the efficacy of EVL vs TAC in the ISS maintenance triple therapy. Ninety-seven kidney transplant patients, who received triple maintenance therapy with TAC, mycophenolate mofetil (MMF), and methyl prednisone (PRED), were evaluated. After four months of post-kidney transplant therapy, 30 patients enrolled in a randomized controlled clinical trial, in which 16 patients received TAC+MMF+PRED (cohort 1), and 14 patients switched to EVL+MMF+PRED (cohort 2). The patients were followed-up for 36 months. Two patients from cohort 1 lost their grafts after one year due to non-adherence. Two patients from cohort 2 had intolerance to mTOR inhibitors and were switched back to TAC from EVL. One case (6.25%) in cohort 1 and three cases (21.43%) in cohort 2 of acute T-cell-mediated rejection was observed. Antibody-mediated acute rejection (ABMAR) was observed in four patients (25.0%) in cohort 1, and antibody-mediated chronic rejection (ABMCR) was observed in two patients (12.50%). One patient from cohort 2 lost the graft after 15 months due to polyomavirus infection. The graft survival rate was 87.50% in cohort 1 and 92.86% in cohort 2. This clinical trial showed that the EVL+MMF+PRED triple maintenance therapy was efficacious compared with TAC during 32 months of follow-up. However, further studies are needed to confirm the efficacy of this regimen for long-term graft survival.

ABSTRACT

OBJECTIVE@#To explore the relationship between the change of lymphocyte subsets before and after immunosuppressive therapy (IST) with disease severity of severe aplastic anemia (SAA) and hematologic response to IST.@*METHODS@#The clinical data of 94 patients with SAA/VSAA treated by r-ATG and CsA in our hospital from December 2009 to October 2011 was analyzed retrospectively. Among them, 26 patients who had sequential data of lymphocyte subsets and cytokines before and after treatment were enrolled. The relationship between lymphocyte subsets, cytokine level before IST and disease severity, as well as the relationship between changes if lymphocyte subsets, changes of cytokine and the HR after IST for 6 months was analyzed.@*RESULTS@#There were no statistical differences in the ratio and absolute count of lymphocyte, the ratio and absolute count of each lymphocyte subsets, including CD3@*CONCLUSION@#The hematopoietic recovery and early hematologic remission may be affected by the intensity of immune suppression reflected from the changes of lymphocyte subsets and the immune reconstruction reflected from the recovery of lymphocyte subsets. The immune reconstruction is most significant within 3 months after IST.

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

ABSTRACT BACKGROUND: Autoimmune hepatitis (AIH) is a chronic liver disease, characterized by necroinflammation and autoimmune etiology. Studies evaluating the characteristics of patients with AIH are scarce in Brazil. OBJECTIVE: Our objective was to evaluate the profile of patients with AIH in a specialized center in Southern Brazil and to verify factors related to treatment response. METHODS: this was a retrospective cohort study, which analyzed demographic, epidemiological, clinical, laboratory, and histologic data. Patients with AIH diagnosed according to the criteria of the International Autoimmune Hepatitis Group (IAIHG) were included. In liver biopsies, the degree of fibrosis, histological activity, presence of hepatocyte rosettes, plasma cell infiltrates, and confluent necrosis were evaluated. In the statistical analysis, the significance level was 5%. RESULTS: Forty adults patients diagnosed with AIH were included. The evaluated population predominantly consisted of women (75.0%) and the average age at diagnosis was 44.2 years. The association with extrahepatic autoimmune diseases occurred in 20.0% of cases. Clinically, 35.0% of patients presented with acute onset hepatitis, 37.5% with cirrhosis, and 27.5% with other forms of presentation. The most common clinical manifestation was jaundice (47.5%). Thirty-five patients were treated, and of these, 97.1% used prednisone combined with azathioprine. The average treatment time was 2.7 years. Response to treatment was complete or partial in 30 (85.7%) and absent in 5 (14.3%) patients. There was no statistically significant difference when evaluating response to treatment in relation to forms of presentation, histological findings, and the presence of autoantibodies. Regarding fibrosis, regression was observed in 18.75% of the cases. CONCLUSION: Most patients with AIH were young at presentation and of female sex. The association with extrahepatic autoimmune diseases and cirrhosis at presentation was seen in a considerable proportion of patients. Treatment was effective, but there were no clinical, histological or serological parameters capable of predicting treatment response.


RESUMO CONTEXTO: A hepatite autoimune (HAI) é uma doença hepática crônica, de caráter necroinflamatório e etiologia autoimune. Os estudos que avaliam as características de pacientes com HAI são escassos no Brasil. OBJETIVO: Nosso objetivo foi avaliar o perfil dos pacientes com HAI atendidos em um centro de referência do sul do Brasil e verificar fatores relacionados à resposta ao tratamento. MÉTODOS: Este foi um estudo de coorte retrospectivo, que analisou dados demográficos, epidemiológicos e clínicos. Nas biópsias hepáticas, foram avaliados o grau de fibrose, a atividade histológica, a presença de rosetas, de infiltrado plasmocitário e de necrose confluente. Na análise estatística, o nível de significância foi de 5%. RESULTADOS: Foram incluídos 40 pacientes adultos com diagnóstico de HAI. Houve predomínio do sexo feminino (75,0%), e a média de idade no diagnóstico foi de 44,2 anos. A associação com doenças autoimunes extra-hepáticas ocorreu em 20,0% dos casos. Clinicamente, 35,0% dos pacientes se apresentaram sob forma de hepatite aguda, 37,5% com cirrose e 27,5% com outras formas de apresentação. A manifestação clínica mais comum na apresentação foi a icterícia (47,5%). Trinta e cinco pacientes foram tratados, sendo que destes, 97,1% utilizaram prednisona associada com azatioprina. A média do tempo de tratamento foi 2,7 anos. A resposta ao tratamento foi completa ou parcial em 30 (85,7%) e ausente em 5 (14,3%) pacientes. Não houve diferença estatisticamente significativa quando avaliada a resposta ao tratamento em relação à forma de apresentação, aos achados histológicos e à presença de autoanticorpos. Em relação à fibrose, foi observada regressão em 18,75% dos casos. CONCLUSÃO: A maioria dos pacientes era jovem no momento do diagnóstico e do sexo feminino. A associação com doenças autoimunes extra-hepáticas e com cirrose na apresentação foi vista em uma parcela considerável dos casos. O tratamento foi eficaz, mas não houve parâmetros clínicos, histológicos ou sorológicos capazes de prever a resposta ao tratamento.

ABSTRACT

La alopecia areata es un tipo común de alopecia no cicatricial. Aunque la patogénesis exacta permanece sin dilucidar, se piensa que la alopecia areata tiene una etiología multifactorial en donde se interrelacionan predisposición genética y factores ambientales. En pacientes susceptibles, se han documentado que el estrés, infecciones y microtraumas disminuyen las citoquinas inmunosupresoras que normalmente mantienen el privilegio inmune del folículo piloso. Actualmente no hay terapia curativa para la alopecia areata, aunque ciertos tratamientos pueden inducir el crecimiento del cabello en un porcentaje de pacientes. Se postula que la simvastatina restablece el privilegio inmune y ezetimibe aportaría un efecto inmunomodulador y antiinflamatorio. Se presenta el caso de una mujer de 23 años con alopecia areata, exitosamente tratada con simvastatina y ezetimibe.


Alopecia areata is a common type of non-scarring alo¬pecia. Although the exact pathogenesis remains elusive, alopecia areata is thought to have a multifactorial etiology described as an interplay of genetic predisposition and environmental exposures. In patients with genetic susceptibility, stress, infection, and microtrauma have been documented to decrease immunosuppressive cytokines that generally maintain the hair follicle's immune privilege. There is currently no curative therapy for alopecia areata, although some treatments can induce hair growth in a percentage of patients. It has been postulated that simvastatin reestablishes the immune privilege, and ezetimibe would provide an immunomodulatory and anti-inflammatory effect. We report a case of a 23 years-old woman with alopecia areata successfully treated with simvastatin/ezetimibe.

ABSTRACT

La mastitis granulomatosa idiopática es una enfermedad inflamatoria crónica de causa desconocida y presentación infrecuente, que afecta a mujeres en edad reproductiva. Su presentación clínica similar al carcinoma de mama, sumada al desconocimiento de esta entidad, genera confusión, errores y retrasos en el diagnóstico en gran proporción de los casos, por lo que la histopatología es un requisito fundamental para el diagnóstico correcto de esta enfermedad. Presentamos dos casos de pacientes femeninas con cuadro clínico de mastitis crónica en quienes, tras descartar causas infecciosas y neoplásicas, se estableció el diagnóstico de mastitis granulomatosa idiopática. Se administró terapia inmunosupresora con prednisolona, metotrexate y ácido fólico. Las pacientes tuvieron una adecuada respuesta y se evidenció la resolución del cuadro clínico a las 3 semanas de tratamiento(AU)


Idiopathic granulomatous mastitis is a chronic inflammatory disease of unknown etiology and infrequent presentation. Confusion, delayed and mistaken in diagnosis has been atribuided to the similar clinical manifestation with breast carcinoma, added to the ignorance of this entity, that's why histopathology is a fundamental requirement for the correct diagnosis of this disease. We present two cases of female patients with clinical symptoms of chronic mastitis, in whom a diagnosis of idiopathic granulomatous mastitis was made after ruling out infectious and neoplastic causes(AU)

ABSTRACT

INTRODUCCIÓN: Los síndromes de falla medular (SFM) son trastornos infrecuentes, con una incidencia anual de 2-4 casos por millón. Las opciones de tratamiento incluyen terapia de inmunosupresión (TIS) y restaura ción de la hematopoyesis con trasplante de progenitores hematopoyéticas (TPH). OBJETIVO: Analizar los desenlaces de pacientes pediátricos diagnosticados con SFM tratados en una institución de alta complejidad. PACIENTES Y MÉTODO: Estudio retrospectivo de pacientes pediátricos con diagnóstico de SFM que consultaron a la Fundación Valle del Lili, Cali. Se realizo análisis estadístico descriptivo según SFM adquirida (SFMA) y SFM congénita (SFMC). Los desenlaces incluyeron: tratamiento, complicaciones, supervivencia global (SG) en los trasplantados, calculada con el método Kaplan Meier. RESULTADOS: Se incluyeron 24 pacientes con SFM, edad 6,5 ± 4 años, 50% mujeres. El 58% fue ron SFMC, 9 con anemia de Fanconi, 2 disqueratosis congénita, 2 trombocitopenia amegacariocítica congénita, uno anemia Diamond-Blackfan. Doce pacientes con TPH tuvieron SG a 5 años de 83%. SFMA correspondió al 42%, 6 recibieron TIS-TPH, 3 TIS y 1 TPH, la SG del grupo con TIS-TPH fue 86%. Seis pacientes fallecieron, 4/6 relacionadas con infección. CONCLUSIONES: En esta serie fue mayor el número de casos con SFMC. La SG de los pacientes llevados a TPH es comparable con la reportada en estudios recientes. La causa de muerte predominante fue infecciosa que también se ha reportado previamente. El tratamiento instaurado en los pacientes de esta serie mostró resultados favorables en un centro de alta complejidad en un país latinoamericano.


INTRODUCTION: Bone marrow failure (BMF) syndromes are rare disorders with an annual incidence of 2-4 cases per million. Treatment options include immunosuppressive therapy (IST) and hematopoietic stem cell transplantation (HSCT). OBJECTIVE: To analyze the outcomes of pediatric patients diagnosed with BMF treated in a tertiary care center. PATIENTS AND METHODP: Retrospective study of pediatric patients diagnosed with BMF who consulted at Fundación Valle de Lili, Cali. Descriptive statistical analysis was performed according to Acquired BMF (ABMF) and Inherited BMF (IBMF). The outcomes include treatment, complications, overall survival (OS) in transplant patients, calculated using the Kaplan Meier method. RESULTS: We included 24 patients with BMF, average age 6.5 ± 4 years, and 50% were women. 58% presented IBMF, 9 with Fanconi anemia (FA), 2 dyskeratosis congenita, 2 congenital amegakaryocytic thrombocytopenia, and 1 presented Diamond-Blackfan anemia. 12 patients treated with HSCT had a 5-year OS of 83%. ABMF represented 42%. 6 patients received IST-HSCT, 3 received IST, and 1 received HSCT. The OS of the IST-HSCT group was 86%. Six patients died, four of them related to infection. CONCLUSIONS: In this series, there was a higher number of cases with IBMF. The OS of patients treated with HSCT is similar to that reported in recent studies. The most frequent cause of death was of infectious origin which has also been previously reported. The treatment esta blished in the patients showed favorable results in a Latin American tertiary care center.

ABSTRACT

ABSTRACT Background: The novel coronavirus disease 2019 (COVID-19) pandemic poses a potential threat to patients with autoimmune disorders, including multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD). Such patients are usually treated with immunomodulatory or immunosuppressive agents, which may tamper with the organism's normal response to infections. Currently, no consensus has been reached on how to manage MS and NMOSD patients during the pandemic. Objective: To discuss strategies to manage those patients. Methods: We focus on how to 1) reduce COVID-19 infection risk, such as social distancing, telemedicine, and wider interval between laboratory testing/imaging; 2) manage relapses, such as avoiding treatment of mild relapse and using oral steroids; 3) manage disease-modifying therapies, such as preference for drugs associated with lower infection risk (interferons, glatiramer, teriflunomide, and natalizumab) and extended-interval dosing of natalizumab, when safe; 4) individualize the chosen MS induction-therapy (anti-CD20 monoclonal antibodies, alemtuzumab, and cladribine); 5) manage NMOSD preventive therapies, including initial therapy selection and current treatment maintenance; 6) manage MS/NMOSD patients infected with COVID-19. Conclusions: In the future, real-world case series of MS/NMOSD patients infected with COVID-19 will help us define the best management strategies. For the time being, we rely on expert experience and guidance.


RESUMO Introdução: A mais recente pandemia causada pelo coronavírus SARS-CoV-2 (COVID-19, do inglês coronavirus disease 2019) representa uma ameaça potencial para pacientes com doenças autoimunes, incluindo esclerose múltipla (EM) e transtorno do espectro de neuromielite óptica (NMOSD, do inglês neuromyelitis optica spectrum disorders). Esses pacientes são geralmente tratados com medicamentos imunomoduladores ou imunossupressores que podem alterar a resposta normal do organismo a infecções. Até o momento, não há consenso sobre como o manejo dos pacientes com EM e NMOSD deve ser realizado durante a pandemia. Objetivo: Discutir estratégias para manejar esses pacientes. Métodos: Focamos em como 1) reduzir o risco de infecção por COVID-19, como distanciamento social, telemedicina e exames laboratoriais e de imagem em intervalos mais amplos; 2) manejo de surtos, incluindo evitar tratamento de surto leve e uso de corticoide oral; 3) gerenciar terapias modificadoras de doença, como a preferência por medicamentos associados a menor risco de infecção (interferons, glatirâmer, teriflunomida e natalizumabe) e infusão em intervalo estendido de natalizumabe, quando seguro; 4) individualizar a escolha da terapia de indução para EM (anticorpos monoclonais anti-CD20, alentuzumabe e cladribina); 5) manejar terapias preventivas de NMOSD, incluindo seleção inicial de terapia e manutenção do tratamento atual; 6) manejar pacientes com EM/NMOSD que foram infectados por COVID-19. Conclusão: No futuro, séries de casos de pacientes com MS/NMOSD infectados com COVID-19 nos ajudará a definir as melhores estratégias de manejo. Por enquanto, contamos com a experiência e orientação especializadas.

ABSTRACT

ABSTRACT Background: To analyze the effectiveness and the safety of Sofosbuvir-based regimens to treat patients with chronic hepatitis C virus (HCV) infection and chronic kidney disease (CKD). Methods: A retrospective, observational study in patients with chronic HCV infection and CKD treated with Sofosbuvir-based regimens was performed. Liver fibrosis, comorbidities, HCV genotype and sustained virological resposnse (SVR) at 12th week post-treatment were evaluated. Kidney function was accessed by serum creatinine and glomerular filtration rate (GFR). The assumed level of significance was 5 %. Results: Thirty-five patients were treated. The mean age was 52.1 ± 10.9 years, 19 (54.3 %) were women, 32 (91.4 %) were already kidney transplanted and 3 (8.6 %) were on hemodialysis. The SVR by intention to treat was 88.6 %. The mean GFR was 65.8 ± 28.6 and 63.7 ± 28.3 ml/min pre- and post-treatment respectively (p > 0.05). Treatment was interrupted in 1 (2.85 %) patient due to anemia and in 2 (5.7 %) due to loss of kidney function. Conclusion: Sofosbuvir-based regimens are effective to treat HCV in patients with CKD. In patients with mild CKD this type of therapy seems to be safe.
