Abstract Regeneration of damaged kidney cells using stem cells is the current research approach in the treatment of chronic renal failure (CRF). In the present study, the histopathological and biochemical techniques were used to evaluate stem cells' (SCs) role in treatment of CRF. Sixty-four rats were divided into eight groups. Group I (GI): rats were injected with doxorubicin (15 mg/kg) to initiate CRF. GII-GVII: rats were injected with doxorubicin and treated with SCs (1x106 MSCs or/and 2x104 HSCs/rat) with/without growth factors extract (200 µL/rat) and/or immunosuppressor (cyclosporine A, 5 mg/kg/day). GVIII: rats treated with PBS (100 µL/kg/day). Levels of creatinine, urea and uric acid were increased in rats sera after injection with doxorubicin, while blood electrolyte levels of Na, K, P and Mg were decreased. Also, histopathological abnormalities such as hyalinized blood vessels, degenerated hyalinized glomerulus tubules and cell debris in the lumen and degeneration of renal tissues were observed in these rats. After treatment with SCs, all these parameters restore their normal values with regeneration of the damaged cells as demonstrated in histopathology of the treated groups. It can be concluded that, the use of SCs in treatment of kidney diseases is a promising approach and needs more efforts.

ABSTRACT Objective: To compare the clinical efficacy of two different doses of topical cyclosporine A used in addition to artificial tears in the treatment of patients with meibomian dysfunction and secondary dry eye. Methods: Fifty patients aged 18 to 40 years, who presented to our clinic between June 2020 and June 2021 were included in our study. Patients were divided into two groups as Group A (topical cyclosporine A 0.05%) and Group B (topical cyclosporine A 0.1%). All the patients underwent a detailed ophthalmological examination, basal Ocular Surface Disease Index measurement, and Schirmer 1 and tear break-up time tests at all visits. Results: The mean age was 32±7.1 years in Group A and 30.7±8.5 years in Group B. In Group A, there were 15 women and ten men, and Group B consisted of 14 women and 11 men. There was no difference between the groups in terms of age and gender distribution (p>0.05). Schirmer 1 and tear break-up time results and Ocular Surface Disease Index score also did not significantly differ between the groups (p>0.05). Conclusion: Cyclosporine A 0.05% and 0.1% eye drops were both seen to be effective in managing dry eye disease in patients with meibomian gland dysfunction.

RESUMO Objetivo: Comparar a eficácia clínica de duas doses diferentes de ciclosporina A tópica utilizada além da lágrima artificial no tratamento de pacientes com disfunção da glândula tarsal e olho seco secundário. Métodos: No estudo, foram incluídos 50 pacientes com idades entre 18 e 40 anos, que se apresentaram em nossa clínica entre junho de 2020 e junho de 2021. Os pacientes foram divididos em dois grupos: Grupo A (ciclosporina A 0,05% tópica) e Grupo B (ciclosporina A 0,1% tópica). Todos os pacientes foram submetidos a um exame oftalmológico detalhado, medição basal do Índice de Doença da Superfície Ocular, e testes de Schirmer 1 e de tempo de ruptura em todas as visitas. Resultados: A idade média foi de 32±7,1 anos no Grupo A e 30,7±8,5 anos no Grupo B. No Grupo A, havia 15 mulheres e dez homens, e o Grupo B consistia de 14 mulheres e 11 homens. Não havia diferença significativa entre os grupos em termos de distribuição por idade e gênero (p>0,05). Os resultados do Schirmer 1 e do tempo de ruptura e do Índice de Doenças da Superfície Ocular também não apresentaram diferença significativa entre os grupos (p>0,05). Conclusão: Observou-se que os colírios de ciclosporina A 0,05% e 0,1% são eficazes no tratamento da síndrome do olho seco em pacientes com disfunção da glândula tarsal.

El diagnóstico diferencial entre la enfermedad de injerto contra huésped aguda grave (estadio IV) y la necrólisis epidérmica tóxica pude resultar difícil en el contexto de un paciente trasplantado, ya que ambas tienen presentaciones clínicas similares. Sin embargo, la distinción entre ellas es fundamental porque ocasionan una gran morbimortalidad, y su manejo y pronóstico difieren. Algunas pequeñas diferencias clínicas e histopatológicas son de gran ayuda para el diagnóstico diferencial y el dermatólogo deberá reconocerlas para tomar una conducta correcta y oportuna. Se comunica el caso de un paciente que presentó ampollas y epidermólisis después del trasplante de células hematopoyéticas y en el que se planteó la dificultad diagnóstica para diferenciar entre ambas afecciones.

The differental diagnosis between severe graft-versus-host disease (stage IV) and toxic epidermal necrolysis can be difficult in the context of a transplant patient, since both conditions have similar clinical presentations. However, the distinction between these two entities is critical because they produce great morbidity and mortality and their management and prognosis differ. Some small clinical and histopathological differences are of great help for the differential diagnosis, and the dermatologist must recognize them in order to take a correct and timely conduct. We present the case of a patient who developed blisters and epidermolysis after hematopoietic cell transplantation, and in whom the diagnostic difficulty to differentiate between the two entities was raised.

ABSTRACT Purpose: We evaluated the role of the conjunctival flap rotation technique using 5-fluorouracil and adjuvant therapy with topical cyclosporine A at 0.05% during short pre- and postoperative periods for the prevention of primary pterygium recurrence. Methods: In this prospective study, 76 patients with primary pterygium (76 eyes) were categorized into two groups: the control group with 31 patients who did not receive cyclosporine treatment, and the cyclosporine group with 45 patients who received topical cyclosporine A (0.05%) twice a day, for 10 days before and 10 days after the pterygium excision operations. Patients were examined for disease recurrence, side effects, and complications at 10 and 21 days, and at 2 and 6 months after the operation. Data on demography, systemic diseases, and ophthalmologic histories were obtained from all patients, and these data were analyzed using descriptive statistics involving the absolute and relative percentages of frequency distribution. Goodman test was used for contrasts among multinomial populations to study the association between cyclosporine A and recurrence. Results: Most patients were between 30 and 60 years of age, and 67.1% were women. We confirmed a higher recurrence in patients with occupational sunlight exposure. The cyclosporine A used topically 10 days before and 10 days after the pterygium removal did not significantly reduce the recurrence of the pterygium. Conclusion: Topical 0.05% cyclosporine A when used for 10 days before and 10 days after the pterygium removal does not prevent or reduce the recurrence of primary pterygium.

RESUMO Objetivo: Avaliamos os resultados da técnica de rotação de retalho conjuntival com uso de 5-fluorouracil e terapia adjuvante com ciclosporina A tópica a 0,05%, usada no pré e pós-operatório por curto período, quanto à prevenção da recidiva do pterígio primário Métodos: Estudo prospectivo, com 76 pacientes portadores de pterígio primário (76 olhos), divididos em dois grupos: controle com 31 pacientes que não receberam tratamento com ciclosporina e grupo ciclosporina com 45 pacientes que receberam ciclosporina tópica A (0,05%) duas vezes ao dia, por 10 dias antes e 10 dias após a cirurgia de excisão do pterígio. Os pacientes foram avaliados quanto à recorrência, efeitos colaterais e complicações com 10, 21 dias, 2 e 6 meses de pós-operatório. Dados demográficos, doenças sistêmicas e histórico oftalmológico foram coletados de todos os pacientes e esses dados foram analisados por meio de estatística descritiva envolvendo o percentual absoluto e relativo de distribuição de frequência. O teste de Goodman para contrastes entre populações multinomiais foi utilizado para o estudo da associação entre a ciclosporina A e a recorrência Resultados: A maioria dos pacientes tinha entre 30 e 60 anos e 67,1% eram mulheres. Confirmamos uma maior recorrência em pacientes com exposição ocupacional ao sol. A ciclosporina A tópica utilizada 10 dias antes e 10 dias após a remoção do pterígio não reduziu significativamente a sua recorrência Conclusão: A ciclosporina A tópica a 0,05% quando utilizada por 10 dias no pré e 10 dias no pós-operatório, não previne ou reduz a recidiva do pterígio primário significativamente.

ABSTRACT Objective: To highlight the importance of the new classification criteria for the macrophage activation syndrome (MAS) in systemic juvenile idiopathic arthritis in order to reduce morbidity and mortality outcome related to this disease. Case description: A 12-year-old female patient with diagnosis of systemic juvenile idiopathic arthritis under immunosuppression therapy for two years developed cough, acute precordial chest pain, tachypnea, tachycardia and hypoxemia for two days. Chest tomography showed bilateral laminar pleural effusion with bibasilar consolidation. The electrocardiogram was consistent with acute pericarditis and the echocardiogram showed no abnormalities. Laboratory exams revealed anemia, leukocytosis and increased erythrocyte sedimentation rate, as well as C-reactive protein rate and serum biomarkers indicative of myocardial injury. Systemic infection and/or active systemic juvenile idiopathic arthritis were considered. She was treated with antibiotics and glucocorticoids. However, 10 days later she developed active systemic disease (fever, evanescent rash and myopericarditis with signs of heart failure) associated with macrophage activation syndrome, according to the 2016 Classification Criteria for Macrophage Activation Syndrome in Systemic Juvenile Idiopathic Arthritis. She was treated for five days with pulse therapy, using glucocorticoids, immunoglobulin and cyclosporine A, with improvement of all clinical signs and laboratory tests. Comments: Myopericarditis with signs of heart failure associated with MAS is a rare clinical presentation of systemic juvenile idiopathic arthritis. Macrophage activation syndrome occurs mainly during periods of active systemic juvenile idiopathic arthritis and may be triggered by infection. Knowledge about this syndrome is crucial to reduce morbidity and mortality.

RESUMO Objetivo: Destacar a importância do conhecimento sobre os novos critérios de classificação para síndrome de ativação macrofágica (SAM) na artrite idiopática juvenil sistêmica para reduzir a morbidade e mortalidade desse desfecho. Descrição do caso: Adolescente do sexo feminino de 12 anos de idade, em terapia imunossupressora por diagnóstico de artrite idiopática juvenil sistêmica há 2 anos, com quadro de tosse, dor precordial aguda, taquipneia, taquicardia e hipoxemia há 2 dias. A tomografia de tórax evidenciou efusão pleural laminar bilateral com consolidação bibasal. O eletrocardiograma foi compatível com pericardite aguda, e o ecocardiograma foi normal. Os exames laboratoriais revelaram anemia, leucocitose e aumento da velocidade de hemossedimentação, proteína C-reativa e marcadores séricos de lesão miocárdica. Infecção sistêmica e/ou doença sistêmica em atividade foram consideradas. A paciente foi tratada com antibióticos e glicocorticoide. Entretanto, dez dias depois, evoluiu com doença sistêmica em atividade (febre, exantema e miopericardite com insuficiência cardíaca) associada à SAM, de acordo com o 2016 Classification Criteria for Macrophage Activation Syndrome in Systemic Juvenile Idiopathic Arthritis, e necessitou de cinco dias de pulsoterapia com glicocorticoide, imunoglobulina e ciclosporina A, com melhora de todos os parâmetros clínicos e laboratoriais. Comentários: A miopericardite com sinais de insuficiência cardíaca associada à SAM é uma apresentação clínica rara da artrite idiopática juvenil sistêmica, que ocorre principalmente em períodos de atividade sistêmica da doença e pode ser deflagrada por infecções. O conhecimento sobre essa síndrome é fundamental para reduzir morbidade e mortalidade desse grave desfecho.

ABSTRACT Introduction: Anemia is a frequent multifactorial complication of CKD seen in patients on dialysis derived mainly from impaired erythropoietin (EPO) production. A less common cause of anemia in individuals with CKD is pure red cell aplasia (PRCA) secondary to the production of anti-EPO antibodies. Objective: This paper aimed two describe two cases of PRCA secondary to the production of anti-EPO antibodies including choice of treatment, patient progression, and a literature review. Materials: This study included the cases of two patients with CKD on hemodialysis with severe anemia in need of specific investigation and management. Results: Patient 1 with CKD secondary to hypertension treated with EPO for 7 months showed persistent decreases in hemoglobin (Hb) levels despite the subcutaneous administration of increasing doses of EPO; the patient required recurring blood transfusions. Workup and imaging tests were negative for the main causes of anemia in individuals with CKD on dialysis. Patient 2 with CKD secondary to adult polycystic kidney disease had been taking EPO for 2 years. The patient developed severe abrupt anemia the month he was started on HD, and required recurring transfusions to treat the symptoms of anemia. Workup and imaging findings were inconclusive. Specific laboratory tests confirmed the patients had anti-EPO antibodies. After six months of immunosuppressant therapy (corticosteroids + cyclosporine) the patients were stable with Hb > 9.0 g/dl. Conclusion: PRCA is a rare condition among patients on dialysis treated with rhEPO and should be considered as a possible cause of refractory anemia. Treating patients with PRCA may be challenging, since the specific management and diagnostic procedures needed in this condition are not always readily available.

RESUMO Introdução: Anemia é complicação frequente da Doença Renal Crônica (DRC) em pacientes dialíticos. Apresenta caráter multifatorial principalmente pela insuficiente produção de eritropoietina (EPO). Situação rara causadora de anemia na DRC é Aplasia Pura de Células Vermelhas (APCV), em decorrência da produção de anticorpos anti-EPO. Objetivo: Descrever 2 casos de APCV com formação de anticorpos anti-EPO, sua abordagem clínica, evolução e revisão de literatura. Métodos: Dois pacientes em hemodiálise que desenvolveram anemia grave, necessitando investigação e manejo específico. Resultados: Paciente nº 1: feminina, 75 anos, DRC secundária à hipertensão arterial. Após 7 meses com EPO desenvolveu queda persistente em valores de hemoglobina (Hb) mesmo com incremento em doses EPO SC, necessitando transfusões de sangue recorrentes. Extensa investigação laboratorial e de imagem resultou negativa para principais causas de anemia. Paciente nº 2: masculino, 66 anos, DRC secundária à DRPA, há 2 anos em uso de EPO. No mês de entrada em HD desenvolveu anemia severa, também exigindo transfusões recorrentes para tratamento da anemia sintomática. Extensa investigação laboratorial e por imagem, sem chegar a uma conclusão definitiva. Em ambos os casos a presença de anticorpos anti-EPO foi confirmada por exames laboratoriais específicos. Terapia imunossupressora resultou em estabilização do quadro e Hb > 9,0 g/dl em ambos os pacientes, 6 meses após início do tratamento. Conclusão: APCV é condição rara entre pacientes dialíticos que recebem EPOHuR e deve ser lembrada como causa de anemia refratária. Seu manejo específico e diagnóstico laboratorial nem sempre acessível, tornando desafiadora a condução dos casos para o nefrologista.

ABSTRACT Purpose: This study reports the effects of combined use of oral doxycycline and topical cyclosporine on ocular signs, symptoms, and tear film parameters in rosacea patients. Methods: Fifty-four right eyes of 54 patients were included in this study. All patients underwent full ophthalmologic examination-including best corrected visual acuity measurement, slit-lamp anterior segment and fundus examination, tear film break-up time, and Schirmer test-before treatment and six months post-treatment. Patients were divided into two treatment groups. The first group was treated with oral doxycycline 100 mg twice daily for the first month and once daily for the following two months. The second group received topical 0.05% cyclosporine emulsion drops twice daily for six months in addition to the oral doxycycline treatment regimen. All patients received preservati ve-free artificial tear drops, warm compress, eyelash cleaning, and topical corticosteroid drops three times daily for one month. Results: A significant improvement in ocular signs and symptoms was recorded for all patients in groups 1 and 2 after treatment. There was not a significant difference in terms of itching, burning, meibomian gland inspissation, corneal neovascularization, and conjunctival hyperemia score changes between groups 1 and 2. The increases in Schirmer test and break-up time scores were significantly higher in group 2 than in group 1. Conclusions: Our results support the finding that topical cyclosporine in addition to the standard regimen improves tear function, as shown by Schirmer test and break-up time scores, in ocular rosacea patients.

RESUMO Objetivo: Este estudo relata os efeitos do uso combinado de doxiciclina oral e ciclosporina tópica sobre sinais e sintomas oculares e sobre parâmetros do filme lacrimal em pacientes com rosácea. Métodos: Cinquenta e quatro olhos direitos de 54 pacientes foram incluídos no estudo. Todos os pacientes foram submetidos a exame oftalmológico completo - incluindo a melhor medida da acuidade visual corrigida, segmento anterior em lâmpada de fenda e exame de fundo de olho, tempo de ruptura do filme lacrimal e teste de Schirmer - antes do tratamento e após seis meses de tratamento. O primeiro grupo foi tratado com doxiciclina oral 100 mg duas vezes ao dia no primeiro mês e uma vez ao dia nos dois meses seguintes. O segundo grupo recebeu gotas tópicas de emulsão de ciclosporina a 0,05% duas vezes ao dia por seis meses, além do tratamento com doxiciclina por via oral. Todos os pacientes receberam gotas de lágrima artificial sem conservantes, compressas mormas, limpeza de cílios e gotas de corticosteróide tópico três vezes ao dia durante um mês. Resultados: Uma melhora significativa nos sinais e sintomas oculares foi registrada para todos os pacientes do grupo 1 e 2 após o tratamento. Não houve diferença significativa em termos de prurido, queimação, inspeção da glândula meibomiana, neovascularização da cór nea e alterações na pontuação da hiperemia conjuntival entre os grupos 1 e 2. O teste de Schirmer e o aumento do tempo de ruptura no grupo 2 foram significativamente maiores do que no grupo 1. Conclusões: Os autores concluíram que os resultados apoiam a descoberta de que a ciclosporina tópica, além do tratamento padrão, melhora a função lacrimal como demonstrado pelo teste de Schirmer e o tempo de ruptura em pacientes com rosácea ocular.

Background: The first line treatment for patients < 40 years old with aplastic anemia (AA) is allogeneic HLA-identical sibling donor transplantation (SCT). Immunosuppressive therapy (IST) with a combination of Thymoglobuline (ATG) and cyclosporine is used for older patients or those without a donor. Five year overall survival (OS) for both therapies is > 70%. Aim: To report the experience with SCT and ATG for AA in a public hospital. Patients and Methods: AA was diagnosed in 42 patients between 1998 and 2016, according to Camitta criteria. Thirty eight (90%) received treatment, 7 (18%) under 40 years old received SCT, and 31 (82%) IST. The rest were not treated. OS was calculated from date of diagnosis until last control, death or loss from follow up. Results: Complete or partial hematologic response, was obtained in 71% and 58% of cases with SCT and IS, respectively. Five year OS was 71% and 55% with SCT and IST, respectively. No difference in response was observed between horse and rabbit ATG. Conclusions: SCT from an HLA-identical sibling donor had a high response rate and survival. IST instead, had a lower response and survival, due to an initial high mortality rate.

ABSTRACT Objective: To evaluate the technique of uterine transplantation and the use of drugs used in the process of immunosuppression. Methods: We included 12 sows, and immunosuppression was performed with minimal doses of cyclosporine, and cross-match was done to exclude the possibility of blood incompatibility. Hysterectomy was performed in the donor under general anesthesia, with the removal of the aorta and inferior vena cava in monobloc, and anastomosis of these vessels was made in the recipient. Results: Six experiments were performed, and on the immediate postoperative period, five animals had good reperfusion. However, on the seventh postoperative day, histological analysis showed rejection in five animals. Conclusion: The experimental model of uterine transplantation is feasible, but monitoring doses of immunosuppressants is pivotal to prevent rejection episodes.

RESUMO Objetivo: Avaliar a técnica de transplante uterino e o uso de drogas no processo de imunossupressão. Métodos: Foram incluídas 12 porcas, sendo realizada imunossupressão com doses mínimas de ciclosporina, e prova cruzada para afastar a possibilidade de incompatibilidade sanguínea. Realizou-se, na doadora, histerectomia sob anestesia geral, com a retirada, em monobloco, da aorta e da veia cava inferior, de tal forma que, na receptora, fosse possível realizar a anastomose com estes vasos. Resultados: Foram realizados seis experimentos e, no pós-operatório imediato, houve boa reperfusão em cinco animais. Entretanto, no sétimo dia de pós-operatório, as análises histológicas demonstraram rejeição em cinco deles. Conclusão: O modelo experimental de transplante uterino é factível, mas a monitorização das doses de imunossupressores é importante, a fim de impedir os episódios de rejeição.

ABSTRACT Purpose: Administration of eye drops containing antihistamines or sodium cromoglycate and its derivatives for the treatment of allergic keratoconjunctivitis is often insufficient and usually requires the addition of corticosteroids. However, the risk of complications, such as glaucoma and cataract, limits the use of corticosteroids to short courses, resulting in inadequate long-term treatment response. Immunosuppressive drugs have been considered as a valid alternative to steroids for atopic keratoconjunctivitis and vernal keratoconjunctivitis. This study aimed to evaluate the use of topical tacrolimus (TCL) in improving the clinical signs of severe allergic keratoconjuctivitis in children. Methods: Patients with severe allergic keratoconjunctivitis associated with corneal epitheliopathy, gelatinous limbal infiltrates, and/or papillary reaction, along with a history of recurrences and resistance to conventional topical anti-allergy agents, were included in this open clinical trial. Patients were treated with 0.03% TCL ointment for ocular use. A severity score ranging from 0 to 9, with 9 being the highest and 0 being the lowest, was assigned based on signs observed on biomicroscopy prior to and following TCL treatment. Results: Analyses included 66 eyes of 33 patients. After a mean follow-up period of 13 months (range, 12-29 months), TCL treatment significantly decreased the mean symptom score severity for the right (from 5.56 ± 1.18 to 2.76 ± 1.5; p<0.001) and left (from 5.94 ± 1.16 to 2.86 ± 1.64; p<0.001). Conclusion: Topical TCL was effective and significantly improved the clinical signs of allergic keratoconjuctivitis in children. Thus, it is a potential new option for severe and challenging cases of ocular allergy.

RESUMO Objetivos: O tratamento da ceratoconjuntivite alérgica baseado em colírios que contenham anti-histamínicos ou cromoglicato de sódio e seus derivados geralmente são insuficientes. A adição de corticosteróides geralmente é mandatória. No entanto, o risco de complicações como glaucoma e catarata limita o uso dos corticosteróides em curtos períodos de tratamento resultando em respostas inadequadas a longo prazo. Drogas imunossupressoras vem sendo consideradas como uma opção terapêutica alternativa válida para as ceratoconjuntivite atópica (AKC) e ceratoconjuntivite vernal (VKC). Este trabalho tem como objetivo avaliar a melhora nos sinais clínicos durante o uso de tacrolimus (TCL) tópico em crianças com ceratoconjuntivites alérgicas. Métodos: Pacientes com ceratoconjuntivite alérgica severa associada a ceratites, infiltrados limbares gelatinosos e/ou papilas gigantes, com história de recorrências e resistência ao tratamento anti-alérgico tópico convencional foram incluídos neste estudo. Os pacientes foram tratados com TCL 0,03% pomada tópica para uso ocular. Um escore variando de 0 a 9 foi atribuído para os sinais observados na biomicroscopia antes e depois do tratamento. Quanto maiores os escores, mais severos eram os sinais. Resultados: Foram estudados 66 olhos de 33 pacientes. Antes do tratamento a média do escore para o olho direito foi 5,56 ± 1,18 e para o olho esquerdo 5,94 ± 1,16. Após o tratamento com TCL a média do escore para o olho direito foi 2,76 ± 1,5 e para o olho esquerdo 2,86 ± 1,64 (p<0.001 para os dois olhos). O tempo de seguimento médio foi de 13 meses (12-29 meses). Conclusão: O presente estudo sugere que o TCL tópico foi efetivo e demonstrou resultado satisfatório, com melhora nos sinais clínicos na ceratoconjuntivite alérgica em crianças, constituindo uma nova opção para o tratamento de casos severos de alergia ocular.

Background: Drug interactions (DI) in patients receiving hematopoietic stem cell transplantation (HSCT) are common and clinically significant, highlighting: anticonvulsants, voriconazole (VCZ) and cyclosporine (CsA), which require monitoring. Objective: To describe the interactions between CsA-VCZ in children undergoing HSCT. Methods: Retrospective, descriptive study in immunocompromised children hospitalized since January 2013 to December 2014 at Bone Marrow Transplant Unit, Hospital Dr. Luis Calvo Mackenna, who received CsA and VCZ. Results: The median age was 5 years (3-6) and the median weight was 20 kg (17-30). Sixtythree baseline drug levels were analyzed, of those, 27 were CsA drug levels obtained previous to using VCZ and 36 were CsA drug levels collected concomitantly with VCZ. In the group CsA previous to VCZ, the CsA dose was 4.6 ± 2.6 (mg/ kg/ day) and the CsA average level was 188.8 ± 84.1 (μg/ml). In the group of CsA concomitantly with VCZ, the dose of CsA was 5.5 ± 3.0 (mg/ kg/day) (p = 0.07) and CsA average level was significantly higher: 232.5 ± 106.7 (μg/ml) (p = 0.04). Conclusion: This study shows an increased level of CsA when it is used together with VCZ. Therapeutic drug monitoring could improve the management of the DI and optimize the co-administration of CsA and VCZ.

Introducción: Las interacciones medicamentosas (IM) en el trasplante de progenitores hematopoyéticos (TPH) son comunes y clínicamente significativas, especialmente en: anticonvulsivantes, voriconazol (VCZ) y ciclosporina (CsA). Objetivo: Describir las interacciones de CsA-VCZ en pacientes con TPH. Métodos: Estudio descriptivo, retrospectivo, en pacientes receptores de TPH entre enero de 2013 y diciembre de 2014 en la Unidad de Trasplante de Médula Ósea del Hospital Dr. Luis Calvo Mackenna, que recibieran CsA y VCZ. Resultados: Edad media: 5 años (3-6), peso promedio: 20 kg (17-30). Se analizaron 63 concentraciones plasmáticas de CsA, 27 eran concentraciones de CsA previas al uso de VCZ y 36 concentraciones plasmáticas de CsA concomitantes con VCZ. En el grupo de CsA previo a VCZ, la dosis de CsA fue 4,6 ± 2,6 (mg/kg/día) y la concentración media de CsA 188,8 ± 84,1 (μg/ml). En el grupo de CsA en forma concomitante con VCZ, la dosis de CsA fue de 5,5 ± 3,0 (mg/kg/día) (p 0,07) y la concentración media de CsA fue: 232,5 ± 106,7 (μg/ml) (p = 0,04). Conclusión: Se demostró un aumento de las concentraciones plasmáticas de CsA en IM con VCZ. La monitorización terapéutica podría mejorar el manejo de la IM y optimizar la coadministración de CsA y VCZ.

Abstract: The use of calcineurin inhibitors (CNI) after liver transplantation is associated with post-transplant nephrotoxicity. Conversion to mycophenolate mofetil (MMF) monotherapy improves renal function, but is related to graft rejection in some recipients. Our aim was to identify variables associated with rejection after conversion to MMF monotherapy. Conversion was attempted in 40 liver transplant recipients. Clinical variables were determined and peripheral mononuclear blood cells were immunophenotyped during a 12-month follow- up. Conversion was classified as successful (SC) if rejection did not occur during the follow-up. MMF conversion was successful with 28 patients (70%) and was associated with higher glomerular filtration rates at the end of study. It also correlated with increased time elapsed since transplantation, low baseline CNI levels (Tacrolimus ≤ 6.5 ng/mL or Cyclosporine ≤ 635 ng/mL) and lower frequency of tacrolimus use. The only clinical variable independently related to SC in multivariate analysis was low baseline CNI levels (p = 0.02, OR: 6.93, 95%, CI: 1.3-29.7). Mean baseline fluorescent intensity of FOXP3+ T cells was significantly higher among recipients with SC. In conclusion, this study suggests that baseline CNI levels can be used to identify recipients with higher probability of SC to MMF monotherapy. identification: NCT01321112.

PURPOSE: The increased tolerability of enteric-coated mycophenolate sodium (EC-MPS), compared to mycophenolate mofetil, among kidney transplant recipients has the potential to facilitate cyclosporine (CsA) minimization. Therefore, a prospective trial to determine the optimum EC-MPS dose in CsA-based immunosuppression regimens is necessary. MATERIALS AND METHODS: A comparative, parallel, randomized, open-label study was performed for 140 patients from four centers to compare the efficacy and tolerability of low dose CsA with standard dose EC-MPS (the investigational group) versus standard dose CsA with low dose EC-MPS (the control group) for six months in de novo kidney transplant recipients. Graft function, the incidence of efficacy failure [biopsy-confirmed acute rejection (BCAR), death, graft loss, loss to follow-up], and adverse events were compared. RESULTS: The mean estimated glomerular filtration rate (eGFR) of the investigational group at six months post-transplantation was non-inferior to that of the control group (confidence interval between 57.3 mL/min/1.73m² and 67.4 mL/min/1.73 m², p0.05) in the incidence of discontinuations and serious adverse events (SAE) between the groups. CONCLUSION: CsA minimization using a standard dose of EC-MPS kept the incidence of acute rejection and additional risks as low as conventional immunosuppression and provided therapeutic equivalence in terms of renal graft function and safety issues.

Problema de investigación: Calcular los costos y la efectividad esperados de everolimus más ciclosporina y corticosteroide (ECC) comparado con micofenolato más ciclosporina y corticoesteroide (MCC) para el tratamiento de pacientes colombianos, adultos, receptores de trasplante de corazón por primera vez, que han iniciado la terapia de inducción de inmunosupresión y que se perfilan para el tratamiento de mantenimiento. Tipo de evaluación económica Análisis de costo-efectividad. Población objetivo: Pacientes colombianos, adultos, receptores de trasplante de corazón por primera vez, que han iniciado la terapia de inducción de inmunosupresión y que se perfilan para el tratamiento de mantenimiento. Intervención y comparadores I: Everolimus más ciclosporina (dosis reducida) y corticosteroide (ECC). C: Micofenolato más ciclosporina (dosis estándar) y corticoesteroides (MCC). Horizonte temporal: Vital. Perspectiva Sistema General de Seguridad Social en Salud (SGSSS). Tasa de descuento: Se emplea una tasa de descuento común tanto para los costos como para los desenlaces en salud equivalente al 5 % anual. Adicionalmente, se realizan análisis de sensibilidad de 0 %, 3,5 %, 7 % y 12 %. Estructura del modelo: Modelo de Markov anidado en un árbol de decisiones. Fuentes de datos de efectividad y seguridad: Fueron empleados los recursos siguientes: el Reporte de efectividad y seguridad de las alternativas a evaluar previamente publicado por el IETS, los resultados de una búsqueda de literatura económica en las bases de datos del CRD y los de una búsqueda manual de literatura económica y clínica, además de la información obtenida en la consulta a expertos clínicos. Desenlaces y valoración: Años de vida ganados. Desenlaces y valoración: Años de vida ganados. Costos incluidos: Costos directos de atención: Costos de medicamentos, Costos de procedimiento. Fuentes de datos de costos SISMED: Medicamentos Manual tarifario ISS 2001: Procedimientos. Resultados del caso base: La administración del esquema ECC como inmunosupresión de mantenimiento para pacientes receptores de trasplante es una estrategia más costosa y menos efectiva, respecto al esquema MCC por lo que se considera una estrategia dominada. Análisis de sensibilidad: La intervención ECC deja de ser dominada sólo cuando la probabilidad de muerte en rechazo agudo con la otra estrategia es del 8,70% o superior, y cuando la probabilidad de presentar rechazo agudo es de 7,88% o inferior; el costo de la atención de los eventos adversos crónicos para la estrategia MCC y el costo del esquema EEC, son las variables respecto a las cuales el costo total \r\nparece tener mayor sensibilidad. La curva de aceptabilidad muestra que para el umbral considerado de 3 veces el PIB per cápita, el esquema con everolimus tiene una probabilidad de ser costo efectiva del 15,6%.\r\nConclusiones y discusión: En la práctica clínica actual, everolimus se administra como componente de los esquemas de inmunosupresión de mantenimiento sólo en situaciones particulares tales como terapia escalada en inmunosupresión (en caso de rechazo con terapia estándar), vasculopatía del injerto, disfunción renal o neoplasias. El esquema más usado en la práctica asistencial actual es el que incluye micofenolato más ciclosporina y prednisona (un corticosteroide), que es el indicado para todos los pacientes trasplantados. Los estudios clínicos desarrollados que han comparado estos dos esquemas \r\nconcluyen que tienen un perfil semejante de efectividad y seguridad y el acá desarrollado clasifica el esquema con everolimus como una estrategia dominada.(AU)

Resultados del caso base: Los resultados del caso base para la administración del esquema ECC como inmunosupresión de mantenimiento para pacientes receptores de trasplante es una estrategia más costosa y más efectiva, respecto al esquema MCC; no obstante, si se asume que la disposición a pagar es 3 veces el PIB per cápita por un años de vida ganado, la estrategia ECC no es costo efectiva por superar dicho umbral. Análisis de sensibilidad: Este resultado se mantiene en todos los escenarios planteados excepto para los casos en los cuales la probabilidad de pérdida del injerto ante presencia de rechazo agudo en el esquema MCC toma valores superiores al 8%, cuando los costos del esquema de medicamentos ECC son inferiores a $4.083.749, y cuando la probabilidad de presentar eventos adversos crónicos con la estrategia ECC es inferior al 25%. Conclusiones y discusión: En la práctica clínica actual, everolimus se administra como componente de los esquemas de inmunosupresión de mantenimiento sólo en situaciones particulares como estrategia de conversión si se presenta toxicidad renal por ciclosporina, cáncer de piel u otro tipo de cáncer que se encuentra en riesgo de aumentar su tasa de crecimiento, o ante eventos como la hiperplasia gingival entre los más comunes. El esquema más usado en la práctica asistencial actual es el que incluye micofenolato más ciclosporina y prednisona, indicado para todos los pacientes trasplantados. Los estudios clínicos desarrollados que han comparado estos dos esquemas concluyen que tienen un perfil semejante de efectividad y seguridad y el acá desarrollado clasifica el esquema con everolimus como una estrategia no costo efectiva.

ABSTRACTPurpose:To evaluate the effectiveness of topical 1% cyclosporine eye drops diluted in either of the two vehicles-olive and linseed oil-and that of the oils themselves in treating experimentally-induced keratoconjunctivitis sicca (KCS) in rabbits.Methods:KCS was induced in 25 New Zealand rabbits using 1% atropine sulfate eye drops for 7 days before treatment and throughout the treatment period (12 weeks). The rabbits were divided into five groups: one control (C) group without KCS induction and four treatment groups in which KCS was induced and treated topically with olive oil (O), linseed oil (L), cyclosporine in olive oil (CO), and cyclosporine in linseed oil (CL). The animals were evaluated using Schirmer tear test 1 (STT), the fluorescein test (FT), tear-film break-up time (TBUT), the rose bengal test (RBT), and histopathological analysis.Results:Values of STT and TBUT significantly decreased 1 week post-induction (p<0.05) and were similar to initial values after the 4th week of treatment, in all groups. After KCS induction, there was significantly less corneal damage in group L than in group CL, as assessed FT and RBT. Histopathology demonstrated that Groups L and CL presented less edema and corneal congestion. There was no significant difference in the goblet cell density (cells/mm2) between the groups (p=0.147).Conclusion:Cyclosporine diluted in olive oil or linseed oil was effective in the treatment of KCS, although it had better efficacy when diluted in linseed oil. Linseed oil presented better effectiveness, whether associated or not, than olive oil. These results may contribute to the creation of novel topical ophthalmic formulations for KCS treatment in future.

RESUMOObjetivo:Avaliar a eficácia do uso tópico do colírio de ciclosporina 1% em dois veículos, óleo de oliva e linhaça, e dos óleos separados, no tratamento da ceratoconjuntivite seca experimentalmente induzida (KCS) em coelhos.Método:Vinte e cinco coelhos Nova Zelândia foram induzidos para KCS com colírio de sulfato de atropina a 1% por sete dias antes e durante o período de tratamento (12 semanas) e foram divididos em 5 grupos, um grupo controle (C), sem indução de KCS e quatro grupos de tratamento tópico com ciclosporina em óleo de oliva (CO), ciclosporina em óleo de linhaça (CL), óleo de oliva (O) e óleo de linhaça (L). Os animais foram avaliados utilizando o teste lacrimal de Schirmer I (STT), teste de fluoresceína (FT), teste de ruptura do filme lacrimal (TBUT), teste de rosa bengala (RBT) e análise histopatológica.Resultados:Os valores de TBUT e STT diminuíram significativamente uma semana pós-indução da KCS (p<0,05) e foram semelhantes aos valores iniciais após a quarta semana de tratamento, em todos os grupos. Após a indução de KCS, houve menor dano na córnea no grupo L em relação ao grupo CL, quando avaliados FT e RBT. A histopatologia demonstrou que os grupos L e CL apresentaram menos edema e congestão da córnea. Não houve diferença significativa na densidade das células caliciformes (células/mm2) entre os grupos (p=0,147).Conclusão:Ciclosporina diluída em óleo de oliva ou linhaça foi eficiente no tratamento da CCS, porém teve uma melhor eficácia quando diluída no óleo de linhaça. O óleo de linhaça, isoladamente ou associado, apresentou melhor eficácia quando comparado ao óleo de oliva. Estes resultados podem contribuir no futuro com novas formulações oftálmicas tópicas no tratamento da CCS.

O transplante cardíaco em crianças tem sido opção nas cardiopatias congênitas complexas e nas cardiomiopatias refratárias a terapêutica convencional. A investigação diagnóstica da etiologia das cardiopatias tem avançado na última década como, por exemplo, a sequência de exons. A assistência circulatória tem sido utilizada como ponte para transplante e no tratamento de rejeições agudas e crônicas. Do ponto de vista imunológico, a prova cruzada virtual no momento do transplante principalmente para os pacientes sensibilizados tem sido útil e fundamental. Novas drogas imunossupressoras como tacrolimo, sirolimo e rituximabe apresentam-se como promissoras na prevenção e tratamento da rejeição. O transplante com sitema ABO incompativel é uma possibilidade para recém-nascidos pela escassez de doadores.

Heart transplant in children has been an option in complex congenital heart disease and cardiomyopathies that do not respond to conventional treatment. The diagnostic investigatio nof the etiology of heart disease has advanced in the last decade, an example of this being exon sequencing. Circulatory support has been used as a bridge to transplantation, and in the treatment of acute and chronic rejections. From an immunological point of view,the virtual crossmatch test at the time of transplant, particularly for sensitized patients, has been useful and essential. New immunosuppressant drugs such as tacrolimus, sirolimusand rituximab have shown promise in the prevention and treatment of rejection. ABO--incompatible transplantation is a possibility for newborn infants, due to the lack of donos.

PURPOSE: To compare the recurrence rates and complications associated with instillation of topical mitomycin C, cyclosporine, and bevacizumab after primary pterygium surgery. METHODS: Between July 2013 and June 2014, we performed surgery using the bare sclera method on 132 eyes (132 patients) with primary pterygium. We randomly selected 33 eyes (33 patients) and treated them with artificial tears four times a day for three months, 29 eyes (29 patients) were treated with topical 0.02% mitomycin C four times a day for five days, 34 eyes (34 patients) were treated with topical 0.05% cyclosporine four times a day for three months, and 36 eyes (36 patients) were treated with topical 2.5% bevacizumab four times a day for three months after surgery. We prospectively determined the recurrence rates of pterygium and complications at the six-month follow-up examination. RESULTS: At six months after surgery, the recurrence rates in each group were as follows: 45.5% (15 eyes) in the control group, 10.3% (three eyes) in the mitomycin C group, 20.6% (seven eyes) in the cyclosporine group, and 41.7% (15 eyes) in the bevacizumab group (p = 0.004). No serious complications, except subconjunctival hemorrhages, were observed in any group. CONCLUSIONS: Groups receiving topical 0.02% mitomycin C and 0.05% cyclosporine after surgery showed lower recurrence rates than the control group; however, no difference in recurrence rate was observed between the control group and the group receiving topical 2.5% bevacizumab after surgery.

A DOENÇA: A doença de Crohn (DC) é uma doença inflamatória intestinal de origem não conhecida, caracterizada pelo acometimento focal, assimétrico e transmural de qualquer porção do tubo digestivo, da boca ao ânus. Apresenta-se sob três formas principais: inflamatória, fistulosa e fibroestenosante. Os segmentos do tubo digestivo mais acometidos são íleo, cólon e região perianal. A DC não é curável clínica ou cirurgicamente, e sua história natural é marcada por agudizações e remissões. TRATAMENTO: O tratamento clínico dessa doença é feita com aminossalicilatos, corticosteroides, antibióticos e imunossupressores e objetiva a indução da remissão clínica, melhora da qualidade de vida e, após, manutenção da remissão. EVIDÊNCIAS CIENTÍFICAS: Apesar de não existirem estudos controlados, alguns autores indicam ciclosporina devido à gravidade do quadro clínico, e revisão sistemática da Cochrane sobre o uso de ciclosporina oral para indução de remissão em DC concluiu por falta de evidências consistentes de benefício clínico relevante. Em apenas um dos quatro estudos incluídos na revisão foi observado benefício estatisticamente significativo com a dose média de 7,6 mg/Kg/dia. Este estudo, entretanto, teve limitações importantes, como um pequeno número de participantes, e o uso de escala de avaliação clínica não validada. Nos outros três estudos, com doses até 5 mg/Kg/dia, em esquema de uso isolado ou com corticosteroide, não foi observada superioridade em termos de melhora clínica ou obtenção de remissão comparativamente com o placebo. Efeitos adversos, entre os quais nefrotoxicidade, foram mais comuns com a ciclosporina do que com o placebo em todos os estudos. Os autores concluem que a ciclosporina oral não tem seu uso justificado no tratamento de indução ou de manutenção da Doença de Crohn. CONSIDERAÇÕES FINAIS: Com a exclusão da ciclosporina oral no âmbito do Protocolo Clínico e Diretrizes Terapêuticas da Doença de Crohn, vale ressaltar que a apresentação em cápsulas deve continuar compatível com os demais códigos da CID constantes do Componente Especializado da Assistência Terapêutica - CEAF/DAF, inclusive aqueles da Retocolite Ulcerativa. DELIBERAÇÃO FINAL: A CONITEC, na presença dos membros, na reunião do plenário do dia 02/07/2015 deliberou por unanimidade recomendar a exclusão da ciclosporina na apresentação oral para o tratamento da doença de Crohn conforme Protocolo Clinico e Diretrizes Terapêuticas estabelecidos pelo Ministério da Saúde. Foi assinado o Registro de Deliberação nº 128/2015. DECISÃO: PORTARIA Nº 38, de 24 de julho de 2015 - Torna pública a decisão de excluir a ciclosporina na apresentação oral para o tratamento da doença de Crohn no âmbito do Sistema Único de Saúde - SUS.
