Treatment of oral chronic graft-versus-host disease: a retrospective cohort study / Tratamento da doença do enxerto contra hospedeiro crônica oral: um estudo de coorte retrospectivo

ABSTRACT Objective The aim of this study was to evaluate patients with complete response of oral chronic graft-versus-host disease to immunosuppressive treatment. Methods A total of 29 patients submitted to allogeneic hematopoietic stem cell transplantation, with oral chronic graft-versus-host disease, were enrolled in this retrospective study, from September 2012 to February 2018. Patients were treated with combined topical dexamethasone solution and topical tacrolimus ointment, combined topical dexamethasone and topical tacrolimus, systemic immunosuppressive medication, and topical dexamethasone only. Results The mean time of complete response of lichenoid lesions, erythema, and ulcers using dexamethasone and systemic immunosuppressive medication was of 105, 42 and 42 days, respectively (p=0.013).When we associated dexamethasone, tacrolimus and systemic immunosuppressive medication, the mean time of complete response of lichenoid lesions, erythema and ulcers was of 91,84 and 77 days (p=0.011). When dexamethasone was used alone, the mean time of complete response of lichenoid lesions, erythema and ulcers was 182, 140, 21 days, respectively (p=0.042). Conclusion Our study shows that lichenoid lesions require more time to heal. Notably, lichenoid lesions tend to respond better to dexamethasone combined with tacrolimus and systemic immunosuppressive medication, whereas erythema and ulcers respond better to dexamethasone combined with systemic immunosuppressive medication and dexamethasone only, respectively.

RESUMO Objetivo Avaliar os pacientes com resposta completa da doença do enxerto contra hospedeiro crônica oral ao tratamento com imunossupressor. Métodos Vinte e nove pacientes submetidos ao transplante alogênico de células tronco hematopoiéticas, com doença do enxerto contra hospedeiro crônica oral, foram incluídos neste estudo retrospectivo, de setembro de 2012 a fevereiro de 2018. Os pacientes foram tratados com dexametasona para bochecho associada ao tacrolimo pomada, dexametasona para bochecho associada ao tacrolimo tópico, tratamento imunossupressor sistêmico, e dexametasona tópica apenas. Resultados O tempo médio para resposta completa das lesões liquenoides, eritema e ulcerações usando dexametasona e imunossupressor sistêmico foi de 105, 42 e 42 dias, respectivamente (p=0,013). Quando a dexametasona estava associada ao tacrolimo e a medicação imunossupressora sistêmica, o tempo médio para resposta completa das lesões liquenóides, eritema e ulcerações foi de 91, 84 e 77 dias (p=0,011). Quando foi utilizada apenas dexametasona, o tempo médio para resposta completa das lesões liquenoides, eritema e ulcerações foi de 182, 140 e 21 dias, respectivamente (p=0,042). Conclusão Nosso estudo mostra que as lesões liquenoides requerem mais tempo para cicatrização completa. É notável que as lesões liquenoides tendem a responder melhor ao tratamento da dexametasona combinada com o tacrolimo e o imunossupressor sistêmico. Já o eritema e as ulcerações respondem melhor à dexametasona combinada com medicação imunossupressora sistêmica, e dexametasona apenas, respectivamente.

Síndrome doloroso por inhibidores de la calcineurina: reporte de 4 casos en pacientes con retrasplante renal / Calcineurin-inhibitor induced pain syndrome: a 4-case report on patients with kidney retransplantation

INTRODUCCIÓN: El trasplante renal es el tratamiento de elección para pacientes con insuficiencia renal crónica. Los inmunosupresores como los inhibidores de la calcineurina pueden estar asociados a efectos adversos. El Síndrome Doloroso por Inhibidores de la Calcineurina (SDIC) se caracteriza por dolores óseos simétricos, agudos e incapacitantes de miembros inferiores, e imágenes características en la resonancia magnética. Se presentan 4 casos de SDIC con retrasplante renal, uso de tacrolimus como inmunosupresor y diagnóstico por resonancia magnética. MATERIAL Y MÉTODOS: Cuatro pacientes (3 mujeres y 1 varón) que se retrasplantaron con riñones cadavéricos, entre marzo de 2014 y septiembre de 2015, presentaron fuertes dolores en miembros inferiores. Tacrolimus fue el principal agente inmunosupresor. Se realizaron resonancias magnéticas de miembros inferiores, se indicó tratamiento y ajuste en la dosis de tacrolimus. RESULTADOS: El SDIC comenzó a los 2 meses del trasplante y 2 semanas de la detección de niveles tóxicos de tacrolimus. El cuadro doloroso permaneció aproximadamente 2 semanas y fue cediendo. La localización fue exclusiva de miembros inferiores (rodillas, tobillos y pies). El dolor fue referido por los pacientes como agudo, punzante, incapacitante y empeoraba de pie. La resonancia magnética confirmó el diagnóstico, revelando un patrón de edema de médula ósea en meseta tibial y astrágalos. Todos los casos fueron reversibles con el tratamiento indicado. CONCLUSIONES: Reportamos la aparición de SDIC en 4 pacientes con retrasplante renal, uso de tacrolimus y buena evolución. El diagnóstico se basó en sospecha clínica, forma de presentación e imágenes típicas en las resonancias magnéticas

INTRODUCTION: Kidney transplant is the first-line therapy for chronic kidney disease. Immunosuppressants such as calcineurin-inhibitors may be associated with side effects. Calcineurin-inhibitor induced pain syndrome (CIPS) is characterized by symmetrical, severe and disabling bone pain in the lower limbs and can be easily identified by magnetic resonance imaging due to its typical patterns. Four CIPS cases after kidney retransplantation are presented, confirmed by MRI and with immunosuppressive therapy consisting of tacrolimus. METHODS: Four patients (3 females and 1 male) with cadaveric kidney retransplantation, performed between March 2014 and September 2015 showed intense pains in their lower limbs. Tacrolimus was the main immunosuppressive agent. MRI scans of the lower limbs were performed; tacrolimus treatment and dosage adjustment were indicated. RESULTS: CIPS started 2 months after transplantation and 2 weeks after detection of tacrolimus toxic levels. Pain lasted around 2 weeks and it gradually became less severe. Symptoms were exclusively located in the lower limbs (knees, ankles and feet). Patients described the pain as sharp, throbbing, disabling, and becoming worse when standing. MRI confirmed the diagnosis, revealing a pattern of bone marrow edema in tibial plateau and tali. All cases were reversible with the indicated treatment. CONCLUSIONS: This study registers 4 cases of CIPS in patients who had undergone kidney retransplantation and had taken tacrolimus with good response. Diagnosis was reached by clinical suspicion, form and location of pain, and characteristic patterns in the MRI scans

Conversion to Mycophenolate Mofetil Monotherapy in Liver Recipients: Calcineurin Inhibitor Levels are Key

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. Clinicaltrials.gov identification: NCT01321112.

Therapy of tacrolimus combined with corticosteroids in idiopathic membranous nephropathy

We evaluated the efficacy and safety of tacrolimus (TAC) combined with corticosteroids in treating patients with idiopathic membranous nephropathy (IMN). One hundred seventy-seven biopsy-proven IMN patients were recruited in this retrospective clinical study. Sixty patients received TAC (target blood concentration of 4–8 ng/mL) and 117 patients received daily cyclophosphamide (CYC, 100 mg) combined with prednisone. Remission rates at the end of the first, second and third month in the TAC group were significantly higher than that in the CYC group (1st: 35.0 vs 19.7%, P<0.05; 2nd: 56.7 vs 38.5%, P<0.05; 3rd: 76.7 vs 59.0%, P<0.05). In the first 3 months, daily urinary protein and serum albumin in the TAC group obtained a better improvement than that in the CYC group (P<0.05). At the end of the sixth and the twelfth month, the remission rates, daily urinary protein and serum albumin were all comparable between the two groups (P>0.05). No significant difference of relapse rate between the groups was found (16.3 vs 12.0%, P>0.05). Patients were more likely to develop glucose intolerance in the TAC group. The TAC regimen obtained more benefits in treating IMN patients, especially in the first 3 months, than the CYC regimen.

Prognostic factors for the evolution and reversibility of chronic rejection in pediatric liver transplantation

OBJECTIVE: Chronic rejection remains a major cause of graft failure with indication for re-transplantation. The incidence of chronic rejection remains high in the pediatric population. Although several risk factors have been implicated in adults, the prognostic factors for the evolution and reversibility of chronic rejection in pediatric liver transplantation are not known. Hence, the current study aimed to determine the factors involved in the progression or reversibility of pediatric chronic rejection by evaluating a series of chronic rejection cases following liver transplantation. METHODS: Chronic rejection cases were identified by performing liver biopsies on patients based on clinical suspicion. Treatment included maintaining high levels of tacrolimus and the introduction of mofetil mycophenolate. The children were divided into 2 groups: those with favorable outcomes and those with adverse outcomes. Multivariate analysis was performed to identify potential risk factors in these groups. RESULTS: Among 537 children subjected to liver transplantation, chronic rejection occurred in 29 patients (5.4%). In 10 patients (10/29, 34.5%), remission of chronic rejection was achieved with immunosuppression (favorable outcomes group). In the remaining 19 patients (19/29, 65.5%), rejection could not be controlled (adverse outcomes group) and resulted in re-transplantation (7 patients, 24.1%) or death (12 patients, 41.4%). Statistical analysis showed that the presence of ductopenia was associated with worse outcomes (risk ratio=2.08, p=0.01). CONCLUSION: The presence of ductopenia is associated with poor prognosis in pediatric patients with chronic graft rejection.

Allogeneic hematopoietic stem cell transplantation in the elderly: Predicting the risk for non relapse mortality

We have retrospectively reviewed 137 medical records of patients older than 50 years receiving an allogeneic hematopoietic stem cell transplantation (HSCT) between January 1997 and July 2013. Median follow up was 1.3 years. Sex, age, diagnosis, disease stage, comorbidities (according to HCT-CI score), type of donor, histocompatibility, conditioning regimen and graft-versus-host disease (GVHD) prophylaxis were evaluated. The incidence and severity of acute and chronic GVHD, overall survival (OS), disease free survival (DFS), non-relapse mortality (NRM) and relapse were investigated according those variables. Acute GVHD incidence was 41% (7.3% GIII-IV). Patients with acute myeloid leukemia had lesser aGVH GII-IV (14% vs. 35%, p < 0.01) comparing to the entire population. Extensive cGVHD incidence was 9.4%. Global OS 1-3 years was 44-20%, DFS 33-20%, relapse 35-41% and NRM 36-43% respectively. The presence of comorbidities showed a significant increase in NRM (CT-CI 0 vs. 1 vs ≥ 2: 1-3 years 17-24% vs. 40-46% vs. 45-67%, p = 0.001, MA HR 2.03, CI 95% 1.02-5.29), as well as cyclosporine vs. tacrolimus (1-3 years 47-53% vs. 25-36%, p = 0.01). Tacrolimus patients had higher 1-3 years OS (49-25% vs. 31-13%, p = 0.01) and DFS (41-26% vs. 20-11%, p < 0.01). Age, type of donor and myeloablative conditioning showed no significant differences in any outcome. Allogeneic HSCT is a valid therapeutic option for older patients in Argentina. The main risk factor for a significantly increased NRM and a trend to inferior OS was the number of comorbidities. Age was not a factor for a worse result. The other factor having a significant effect in better outcome was tacrolimus administration.

Se efectuó un análisis retrospectivo de 137 historias clínicas de pacientes mayores de 50 años que recibieron un trasplante alogénico de precursores hematopoyéticos (TAPH). Se evaluaron las siguientes características: sexo, edad, enfermedad, estadio, comorbilidades (según el HCT-CI), donante, acondicionamiento e inmunosupresión. Se analizó la incidencia de enfermedad injerto vs. huésped aguda (aEICH) y crónica (cEICH), supervivencia global (SG), supervivencia libre de enfermedad (SLE), recaída y mortalidad libre de enfermedad (MLE). Los trasplantes fueron realizados entre 1997-2013, mediana de seguimiento 1.3 años. La incidencia de aEICH fue de 41% (7.3% GIII-IV). Los pacientes con leucemia mieloide aguda presentaron menor incidencia de EICHa GII-IV (14% vs. 34%, p < 0.01). La incidencia de EICHc extenso fue de 9.4%. La SG a 1-3 años fue 44-20%, SLE 33-20%, recaída 35-41% y la MLE 36-43%. Los pacientes con comorbilidades tuvieron un aumento significativo de la MLE (HCT-CI 0 vs. 1 vs. ≥2: 1-3 años 17-24% vs. 40-46% vs. 45-67%, p = 0.001, AMV HR 2.03, IC 95% 1.02-5.29), al igual que el uso de ciclosporina vs. tacrolimus (1-3 años 47-53% vs. 25-36%, p = 0.01). Los pacientes que recibieron tacrolimus tuvieron una mayor SG (1-3 años 49-25% vs. 31-13%, p = 0.01) y SLE (1-3 años 41-26% vs. 20-11%, p < 0.01). La edad, tipo de donante y acondicionamiento no resultaron significativos para ningún evento. El TAPH es una herramienta terapéutica válida en pacientes mayores. Los factores pronósticos que inciden mayormente en el trasplante son las comorbilidades y no la edad. El otro factor que demostró un efecto significativo fue el uso de tacrolimus.

Cyclosporine versus tacrolimus: cost-effectiveness analysis for renal transplantation in Brazil / Análise de custo-efetividade: ciclosporina versus tacrolimo para transplante renal no Brasil

OBJECTIVE To analyze the cost-effectiveness of treatment regimens with cyclosporine or tacrolimus, five years after renal transplantation. METHODS This cost-effectiveness analysis was based on historical cohort data obtained between 2000 and 2004 and involved 2,022 patients treated with cyclosporine or tacrolimus, matched 1:1 for gender, age, and type and year of transplantation. Graft survival and the direct costs of medical care obtained from the National Health System (SUS) databases were used as outcome results. RESULTS Most of the patients were women, with a mean age of 36.6 years. The most frequent diagnosis of chronic renal failure was glomerulonephritis/nephritis (27.7%). In five years, the tacrolimus group had an average life expectancy gain of 3.96 years at an annual cost of R$78,360.57 compared with the cyclosporine group with a gain of 4.05 years and an annual cost of R$61,350.44. CONCLUSIONS After matching, the study indicated better survival of patients treated with regimens using tacrolimus. However, regimens containing cyclosporine were more cost-effective. .

OBJETIVO Analisar custo-efetividade de regimes terapêuticos com ciclosporina ou tacrolimo cinco anos após transplante renal. MÉTODOS Análise de custo-efetividade com base em dados de coorte histórica 2000-2004, com 2.022 pacientes tratados com ciclosporina ou tacrolimo e pareados 1:1 segundo sexo, idade, tipo e ano de transplante. A sobrevida do enxerto e os custos diretos de cuidados médicos a partir das bases de dados do Sistema Único de Saúde foram utilizados como medida de resultado. RESULTADOS A maioria dos pacientes era do sexo feminino e média de idade de 36,6 anos. O diagnóstico mais frequente de insuficiência renal crônica foi a glomerulonefrite/nefrite (27,7%). Em cinco anos, o grupo tacrolimo obteve uma expectativa de vida média de 3,96 anos de vida ganhos ao custo anual de R$78.360,57 ante 4,05 anos de vida ganhos e de R$61.350,44 para ciclosporina. CONCLUSÕES Após o pareamento, o estudo não mostrou melhor sobrevida dos pacientes com regimes que usam tacrolimo. Além disso, regimes contendo ciclosporina foram mais custo-efetivos. .

An analysis of tacrolimus-related complications in the first 30 days after liver transplantation

OBJECTIVES: Orthotopic liver transplantation has improved survival in patients with end-stage liver disease; however, therapeutic strategies that achieve ideal immunosuppression and avoid early complications are lacking. To correlate the dose and level of Tacrolimus with early complications, e.g., rejection, infection and renal impairment, after liver transplantation. From November 2011 to May 2013, 44 adult liver transplant recipients were studied in this retrospective comparative study. RESULTS: The most frequent indication for liver transplantation was hepatitis C cirrhosis (47.7%), with a higher prevalence observed in male patients (68.18%). The ages of the subjects ranged from 19-71 and the median age was 55.5 years. The mean length of the hospital stay was 16.1±9.32 days and the mean Model for End-stage Liver Disease score was 26.18±4.28. There were five cases of acute cellular rejection (11.37%) and 16 cases of infection (36.37%). The blood samples that were collected and analyzed over time showed a significant correlation between the Tacrolimus blood level and the deterioration of glomerular filtration rate and serum creatinine (p<0.05). Patients with infections had a higher serum level of Tacrolimus (p = 0.012). The dose and presence of rejection were significantly different (p = 0.048) and the mean glomerular filtration rate was impaired in patients who underwent rejection compared with patients who did not undergo rejection (p = 0.0084). CONCLUSION: Blood Tacrolimus levels greater than 10 ng/ml were correlated with impaired renal function. Doses greater than 0.15 mg/kg/day were associated with the prevention of acute cellular rejection but predisposed patients to infectious disease. .

Tacrolimus tópico nas lesões cutâneas refratárias da dermatomiosite juvenil / Topical tacrolimus in refractory skin lesions of juvenile dermatomiosytis

A dermatomiosite juvenil (DMJ) é uma doença inflamatória crônica idiopática que afeta principalmente músculos e pele. As lesões cutâneas podem persistir apesar do controle bem-sucedido da miosite. O tacrolimus tópico é um novo agente imunossupressor que tem sido usado no tratamento da dermatite atópica, com poucos relatos de seu uso em miopatias inflamatórias na faixa etária pediátrica. Foram descritos três pacientes com DMJ (dois meninos) com idade atual de 5,7 a 10,6 anos. A terapia inicial administrada para esses pacientes foi: corticosteróide (sistêmico em três e tópico em um), antimalárico em três e metotrexato em dois. Todos apresentavam lesões cutâneas refratárias (eritema malar, eritema difuso e/ou vasculite cutânea) após melhora significativa da fraqueza muscular. Tacrolimus tópico 0,03 por cento foi usado duas vezes ao dia após falha do tratamento prévio. As características das lesões foram avaliadas de acordo com a extensão e a gravidade no início do uso do fármaco e após oito e 16 semanas. Na segunda avaliação (oito semanas), notavelmente um paciente apresentou melhora completa do eritema malar e do eritema difuso em membros e tronco, e dois tiveram melhora parcial do eritema malar e da vasculite cutânea. Na terceira avaliação (16 semanas), dois pacientes tiveram resolução completa das lesões e um apresentava eritema malar persistente e eritema moderado em glúteos e região lombar. No último paciente, a melhora das lesões cutâneas foi alcan-çada apenas após o uso de ciclosporina por 16 semanas. Nenhum deles teve efeitos adversos. Tacrolimus tópico pode ser considerado em pacientes com DMJ e manifestações cutâneas refratárias. Estudos posteriores controlados e randomizados com esse fármaco devem ser realizados nessa doença inflamatória.

Juvenile dermatomyositis (JDM) is a rare idiopathic chronic inflammatory disease that affects mainly muscle and skin. Cutaneous lesions may persist despite successful treatment of myositis. Of note, topical tacrolimus is a new immunosuppressive agent that has been used to treat atopic dermatitis with few reports in pediatric inflammatory myopathies. Three JDM patients (two males) were described, current age from 5.7 to 10.6 years. The initial therapy administered for these patients were: corticosteroid (oral in three and topical in one), antimalarial in three and methotrexate in two. All of them had refractory skin lesions (malar rash, extensive rash and/or cutaneous vasculitis) after significant improvement of muscle weakness. Topical tacrolimus 0.03 percent was used twice daily after failure of previous treatment. The features of lesions were evaluated according to extension and severity at start of drug and after 8 and 16 weeks. At the second evaluation (8 weeks), remarkably one patient had complete improvement of malar rash and extensive rash in limbs and trunk, and two had partial improvement of malar rash and cutaneous vasculitis. At the third evaluation (16 weeks), two patients had complete resolution of lesions and one had persistent malar rash and moderate lumbar and gluteus rash. In the last patient, the improvement of skin lesions was reached only after 16 weeks of cyclosporine use. None of them had adverse effects. Topical tacrolimus could be considered in JDM patients with refractory cutaneous manifestations. Further randomized controlled trials with this agent should be performed in this inflammatory disease.

Use of non-absorbable polypropylene mesh for the treatment of spontaneous renal graft rupture / Uso de una malla no absorbible de polipropileno para el tratamiento de la ruptura espontánea de injerto renal

Renal graft rupture (RGR) is a life-threatening complication of kidney transplantation (KT), frequently associated with rejection and acute tubular necrosis. RGR repair with the use of suture, and corsetage with various materials (including synthetic glue, polyglactin absorbable hemostatic mesh, and lyophilized human dura), is indicated in non-severe cases. However, the employment of non-absorbable synthetic mesh had not been previously reported. Here, a case of a KT from cadaveric donor with RGR associated with acute rejection is reported. The graft was salvaged with the employment of a non-absorbable polypropylene mesh. Six months after KT, the patient remains asymptomatic with normal renal function. To the best of our knowledge, this is the first report of the use of a non-absorbable polypropylene mesh to repair a RGR. In a setting in which economical restrictions are important, the use of non-absorbable synthetic mesh may represent a good option of treatment.

La ruptura del injerto renal (RIR) es una complicación del trasplante renal (TR) que amenaza la vida, y frecuentemente está asociada a rechazo y necrosis tubular aguda. La reparación de la RIR con el uso de sutura y ferulización con varios materiales (incluyendo pegamento sintético, mallas hemostáticas absorbibles de poliglactina y duramadre liofilizada humana) está indicada en los casos no graves. Sin embargo, el empleo de mallas no absorbibles no había sido informado previamente. Aquí se informa el caso de un TR proveniente de donador cadavérico con RIR asociada a rechazo agudo. El injerto fue rescatado con el empleo de una malla no absorbible de polipropileno. Seis meses después del TR el paciente se encuentra asintomático con función renal normal. Hasta donde tenemos conocimiento, éste es el primer informe del uso de una malla no absorbible de polipropileno para reparar una RIR. En un medio con importantes restricciones económicas, el uso de mallas sintéticas no absorbibles puede representar una buena opción de tratamiento.
