Clinical effect of different immunosuppressive treatment regimens in children with ocular myasthenia gravis: a retrospective analysis / 中国当代儿科杂志

OBJECTIVES@#To investigate the clinical effect of different immunosuppressive treatment regimens in children with ocular myasthenia gravis (OMG).@*METHODS@#A retrospective analysis was conducted on 130 children with OMG who were treated in the Department of Neurology, Jiangxi Children's Hospital, from February 2018 to February 2023. According to the treatment regimen, they were divided into four groups: glucocorticoid (GC) group (n=29), mycophenolate mofetil (MMF) group (GC+MMF; n=33), methotrexate (MTX) group (GC+MTX; n=30), and tacrolimus (FK506) group (GC+FK506; n=38). Treatment outcomes and adverse reactions were compared among the groups.@*RESULTS@#After 3 months of treatment, the FK506 group had significantly lower scores of Myasthenia Gravis Quantitative Scale and Myasthenia Gravis-Specific Activities of Daily Living than the other three groups (P<0.05). After 3 months of treatment, the FK506 group had a significantly lower dose of prednisone than the GC group, and after 6 and 9 months of treatment, the MMF, MTX, and FK506 groups had a significantly lower dose of prednisone than the GC group (P<0.05). After 12 months of treatment, the MMF, MTX, and FK506 groups had a significantly lower incidence rate of GC-related adverse reactions than the GC group (P<0.05).@*CONCLUSIONS@#For children with OMG, the addition of various immunosuppressants can reduce the dosage of GC and adverse reactions. Among them, FK506 shows superior efficacy compared to other immunosuppressants in the early treatment of OMG.

Prevalência e tempo de desenvolvimento da hipertensão arterial sistêmica em pacientes após transplante de fígado / Prevalence and time of development of systemic arterial hypertension in patients after liver transplantation

ABSTRACT BACKGROUND: The use of immunosuppressive drugs after liver transplantation (LT) is associated with the development of systemic arterial hypertension (SAH), in addition to other comorbidities of metabolic syndrome. OBJECTIVE: Therefore, the purpose of this study was to analyze the time after use immunosuppressive drugs the patient progresses to SAH, as well as to identify its prevalence and the factors that may be correlated to it. METHODS: A retrospective and longitudinal study was conducted, based on the analysis of medical records of 72 normotensive patients, attended in the transplant unit of a university hospital, between 2016 and 2019. RESULTS: It was observed, on average, 9±6.98 months after immunosuppressive use, the patients were diagnosed with hypertension, and the prevalence of transplanted patients who evolved to SAH in this study was 59.64% (41 patients). In addition, there was a correlation between serum dosage of tacrolimus and the development of SAH (P=0.0067), which shows that tacrolimus has a significant role in the development of SAH. Finally, it was noticed that the development of post-transplantation hypertension indicates a higher risk of the patient presenting the other parameters of metabolic syndrome, as well as a higher impairment in its renal function (P=0.0061). CONCLUSION: This study shows that the patients evolved to SAH in an average of 9±6.98 months after immunosuppressive drug use. We have also found high prevalence of systemic arterial hypertension (59.64%) in patients after liver transplantation, who used calcineurin inhibitors, especially when associated with the use of tacrolimus.

RESUMO CONTEXTO: O uso de imunossupressores pós-transplante de fígado (TF) está associado ao desenvolvimento de hipertensão arterial sistêmica (HAS), além de outras alterações da síndrome metabólica. OBJETIVO: Sendo assim, o objetivo deste estudo foi analisar a partir de quando tempo após o uso do imunossupressor o paciente evolui para HAS, assim como, identificar a sua prevalência e outros fatores que podem estar relacionados, como injuria renal. MÉTODOS: Realizou-se um estudo retrospectivo, longitudinal, baseado em análise de 72 prontuários de pacientes, atendidos na unidade de transplante de um hospital universitário, que não apresentavam hipertensão arterial prévia, entre período de 2016 a 2019. RESULTADOS: Observou-se que, em média, 9±6,98 meses após uso do imunossupressor, os pacientes foram diagnosticados com hipertensão arterial sistêmica, sendo que a prevalência de pacientes transplantados que evoluíram para HAS, neste estudo, foi de 59,64% (41 pacientes). Além disso, verificou-se uma correlação entre a dosagem sérica de tacrolimus e o desenvolvimento de HAS (P=0,0067), o que evidencia que o tacrolimus tem uma atuação significativa no desenvolvimento da hipertensão arterial sistêmica. Por fim, percebeu-se que o desenvolvimento de HAS pós-transplante indica um maior risco de paciente apresentar os outros parâmetros da síndrome metabólica, como também maior prejuízo na sua função renal (P=0,0061). CONCLUSÃO: Este estudo mostra que os pacientes evoluíram para HAS em média 9±6,98 meses após o início do uso do imunossupressor. Verificou-se também alta prevalência de hipertensão arterial sistêmica (59,64%) em pacientes pós-transplante de fígado, que usavam inibidores de calcineurina, principalmente, quando associado ao uso de tacrolimus.

Postoperative serum triglyceride levels in predicting risk of new-onset diabetes mellitus in patients following liver transplantation / 浙江大学学报·医学版

To investigate the postoperative serum triglyceride (TG) levels in predicting the risk of new-onset diabetes mellitus (NODM) in patients following allogeneic liver transplantation. One hundred and forty three patients undergoing allogeneic liver transplantation in Shanghai General Hospital from July 2007 to July 2014 were enrolled in this study. The NODM developed in 33 patients after liver transplantation. The curve of dynamic TG levels in the early period after liver transplantation was generated. Independent risk factors of NODM were determined by univariate and multivariant logistic regression analyses. The clinical value of TG in predicting NODM was analyzed by area under the ROC curve (AUC). Serum TG levels were gradually rising in the first week and then reached the plateau phase (stable TG, sTG) in patients after surgery. The sTG in NODM group were significantly higher than that in non-NODM group (=-2.31, <0.05). Glucocorticoid therapy (=4.054, <0.01), FK506 drug concentration in the first week after operation (=3.482, <0.05) and sTG (=3.156, <0.05) were independent risk factors of NODM. ROC curve analysis showed that the AUC of sTG in predicting NODM was 0.72. TG shows a gradual recovery process in the early period after liver transplantation, and the higher TG level in stable phase may significantly increase the risk of NODM in patients.

Safety and effectiveness of mycophenolate mofetil associated with tacrolimus for liver transplantation immunosuppression: a systematic review and meta-analysis of randomized controlled trials

A combination of immunosuppressants may improve outcomes due to the synergistic effect of their different action mechanisms. Currently, there is no consensus regarding the best immunosuppressive protocol after liver transplantation. This review aimed to evaluate the effectiveness and safety of tacrolimus associated with mycophenolate mofetil (MMF) in patients undergoing liver transplantation. We performed a systematic review and meta-analysis of randomized clinical trials. Eight randomized trials were included. The proportion of patients with at least one adverse event related to the immunosuppression scheme with tacrolimus associated with MMF was 39.9%. The tacrolimus with MMF immunosuppression regimen was superior in preventing acute cellular rejection compared with that of tacrolimus alone (risk difference [RD]=-0.11; p =0.001). The tacrolimus plus MMF regimen showed no difference in the risk of adverse events compared to that of tacrolimus alone (RD=0.7; p=0.66) and cyclosporine plus MMF (RD=-0.7; p=0.37). Patients undergoing liver transplantation who received tacrolimus plus MMF had similar adverse events when compared to patients receiving other evaluated immunosuppressive regimens and had a lower risk of acute rejection than those receiving in the monodrug tacrolimus regimen.

Risk factors for new-onset diabetes mellitus after kidney transplantation (NODAT): a Brazilian single center study

ABSTRACT Objectives: This study aims to verify the new-onset diabetes after kidney transplant (NODAT) incidence in recipients within 1 year after kidney transplantation from a single center in Southern Brazil and to assess the associated conditions. Subjects and methods: A retrospective study of 258 post-renal transplant patients was performed. Demographic (gender, age, ethnic background) and clinical (origin of graft, associated infections, body mass index (BMI) at transplant time and 6 and 12 months after, causes of renal failure, and comorbidities) data were analyzed. All patients were on tacrolimus, mycophenolate mofetil, and prednisone treatment. Patients with and without NODAT were compared. Results: A NODAT incidence of 31.2% was noted 1 year post transplantation. In the univariate analysis, patients with NODAT were older (p = 0.001), mostly had African-American ethnic background (p = 0.02), and had renal failure secondary to high blood pressure (HBP) (p = 0.001). The group of patients with NODAT also had more incidence of post-transplant HBP (p = 0.01), heart failure (p = 0.02), and dyslipidemia (p = 0.001). Logistic regression showed that African-American ethnic background, post-transplant HBP, and dyslipidemia were independently associated with NODAT. Conclusion: This study shows a NODAT incidence that is greater in patients with African-American ethnic background and that is associated with HBP and dyslipidemia.

Miocardiopatía hipertrófica en un recién nacido pretérmino con madre trasplantada renal / Hypertrophic cardiomyopathy in preterm newborn with kidney transplanted mother

La miocardiopatía hipertrófica en el recién nacido es una entidad poco frecuente y de etiología heterogénea. Se han descrito formas transitorias en hijos de madres con diabetes gestacional y en recién nacidos pretérminos expuestos a corticoides tanto prenatal como posnatalmente. Se presenta un caso de un recién nacido pretérmino, hijo de madre trasplantada renal al que se le detectó una miocardiopatía hipertrófica y que había estado expuesto prenatalmente a corticoides y tacrolimus que recibía la madre como tratamiento inmunosupresor. Ambos fármacos cruzan la barrera placentaria y, al llegar al feto, podrían haber favorecido su desarrollo. La miocardiopatía hipertrófica puede ser un efecto secundario poco común del tratamiento con tacrolimus en adultos y niños, y es reversible al retirarlo. En nuestro conocimiento, es el primer caso publicado de miocardiopatía hipertrófica transitoria tras la exposición fetal tanto a corticoides como a tacrolimus en un hijo de madre trasplantada renal.

Hypertrophic cardiomyopathy in the newborn is a rare entity with heterogeneous etiology. Transient forms have been described in children of mothers with gestational diabetes and in preterm infants exposed both to prenatal and postnatal corticosteroids. We report a case of a preterm infant son of a mother who received renal transplant in whom hypertrophic cardiomyopathy was detected. He had been prenatally exposed to corticosteroids and tacrolimus that received the mother as immunosuppressive therapy. Both drugs cross the placental barrier and, on reaching the fetus, could have favored its development. Hypertrophic cardiomyopathy may be an uncommon side effect of treatment with tacrolimus in adults and children and it is reversible upon withdrawal. To our knowledge, it is the first published case of transient hypertrophic cardiomyopathy after fetal exposure to both corticosteroids and tacrolimus in the son of a renal transplanted mother.

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.

Effects of immunosuppression with tacrolimus and mycophenolate mofetil on renal histology and function in single kidney rats submitted to ischemia and reperfusion

PURPOSE: To evaluate renal histological changes and renal function in single kidney rats submitted to renal ischemia-reperfusion and to immunosuppression with tacrolimus and mycophenolate-mofetil. METHODS: Experimental study with 80 Wistar rats distributed into control, Sham and six other groups treated with immunosuppressive drugs. Animals undergoing surgery, right nephrectomy and left renal clamping, killed on the 14th day and analyzed for renal histology, urea and creatinine. RESULTS: The group receiving tacrolimus at higher doses (T3) showed renal histological lesions indicative of early nephrotoxicity, and significant increase in urea and creatinine. The group M (mycophenolate-mofetil alone) and the group M2 (mycophenolate-mofetil combined with half the usual dose of tacrolimus) presented a slight rise in serum urea. The groups using mycophenolate-mofetil alone or combined with tacrolimus showed creatinine levels similar to that of the group T3. CONCLUSIONS: Histologically, the association of injury by ischemia-reperfusion with the use of tacrolimus or mycophenolate-mofetil alone demonstrated a higher rate of renal changes typical of early nephrotoxicity. In laboratory, the combination of injury by ischemia-reperfusion with tacrolimus at higher doses proved to be nephrotoxic. .

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. .

A case of tacrolimus-induced supraventricular arrhythmia after kidney transplantation / Um caso de arritmia supraventricular induzida por tacrolimus, apos o transplante renal

CONTEXT Tacrolimus is a potent immunosuppressive drug often administered to transplant recipient patients and exhibits a variety of adverse cardiovascular effects. CASE REPORT We report a case of a 53-year-old Asian female who developed various arrhythmic phenomena including atrial premature complexes and supraventricular tachycardia after administration of tacrolimus. CONCLUSION Tacrolimus-associated arrhythmia after kidney transplantation may be life-threatening, and so patients undergoing this procedure should be carefully monitored. .

CONTEXTO Tacrolimus (tacrolimo) é uma potente droga imunossupressora frequentemente administrada a pacientes receptores de transplante e exibe uma variedade de efeitos cardiovasculares adversos.

A pilot study on area under curve of mycophenolic acid as a guide for its optimal use in renal transplant recipients.

Background & objectives: The immunosuppressants administered to renal transplant subjects are usually monitored therapeutically to prevent graft rejection and drug toxicity. Mycophenolic acid (MPA) is an immunosuppressant. The present prospective study was undertaken to establish the utility of plasma level monitoring of MPA and to correlate it with clinical outcomes in renal transplant receipients. Methods: MPA plasma level at 2, 4 and 9 h and the area under concentration-time curve (AUC) were estimated using high performance liquid chromatography in 24 renal transplant recipients receiving immunosuppressant MPA plus tacrolimus and steroid. Results: There was wide inter-individual variation in MPA plasma level and the AUC. The incidences of gastrointestinal adverse drug events (diarrhoea and acidity) were significantly more in the high MPA AUC patients. Though biopsy proven acute rejection was not found, of the six subjects with lower MPA AUC (<30 mg.h/l), three were clinically diagnosed to develop tacrolimus nephrotoxicity. The Gastrointestinal Symptom Rating Scale (GSRS) and Gastrointestinal Quality of Life Index (GIQLI) scores represented better health related quality of life in lower MPA AUC than in the higher MPA AUC (>60 mg.h/l). Interpretation & conclusions: The present findings suggest the MPA AUC of 30 - 60 mg.h/l in the maintenance stage of renal transplant patients to have optimum clinical benefit and relegated adverse events profile indicating the usefulness of AUC of MPA with limited sampling strategy in optimizing its use.

Maculopathy Associated with Tacrolimus (FK 506)

A 63-year-old man with a history of liver transplantation presented to our clinic complaining of visual disturbance. He had been receiving tacrolimus (FK 506) for 30 months (6 mg/day for 2 years and 3 mg/day for 6 months); he reported that the visual disturbance began while taking tacrolimus. A full ophthalmologic examination and electrophysiologic and imaging studies were performed. The best corrected visual acuity was 0.1 in both eyes. There were no abnormal finding in the anterior segment, pupillary reflexes were normal and, there was no swelling in either optic disc. Although the foveal reflex was slightly decreased, fluorescein angiography revealed non-specific signs, with the exception of a window defect. A multifocal electro-retinogram revealed decreased amplitude of the central ring. A Swedish interactive threshold algorithm-standard 10-2 visual field test revealed a central scotoma. These findings suggest that tacrolimus may result in maculopathy. Therefore, careful ophthalmologic examination is necessary in the patients taking tacrolimus.

Enfermedad linfoproliferativa difusa postrasplante en adultos: comunicación de un caso y revisión de la literatura / Post-transplant lymphoproliferative disorder in adults: case report and review of the literature

The post-transplant lymphoproliferative disorder (PTLD) corresponds to a heterogeneous group of lymphoproliferative diseases that develop in solid organ and bone marrow transplant recipients. It occurs in 3-10 percent of patients receiving solid organ transplants, mostly children. It is called early PTLD if it occurs in the first year after transplantation, if it affects B-cell lymphocytes and is associated with infection by Epstein-Barr virus. Late presentation occurs after the first year of transplantation and its pathogenesis is less clear. Clinical manifestations vary from a benign mononucleosis-like clinical setting to high-grade tumors with high mortality (40-60 percent). Treatment depends on the extent of the disease, including reduction of immunosuppressive therapy, radiotherapy, surgery and, more recently, the use of anti-CD20 monoclonal antibody. We report the case of a 67 year-old woman presenting with PTLD on the eighth month after receiving a liver graft.

La enfermedad linfoproliferativa difusa postrasplante (ELDP), corresponde a un grupo heterogéneo de desórdenes linfoproliferativos que se desarrollan en receptores de órganos sólidos y médula ósea. Ocurre en 3 a 10 por ciento de los pacientes receptores de órganos sólidos, fundamentalmente pediátricos. Se denomina ELDP precoz si se presenta en el primer año posterior al trasplante, afecta a los linfocitos de estirpe B y se asocia a la infección por virus Epstein-Barr. La presentación tardía ocurre luego del primer año de trasplante y su etiopatogenia es menos clara. Las manifestaciones clínicas varían desde un cuadro benigno similar a la mononucleosis a neoplasias de alto grade, con elevada mortalidad (40-60 por ciento). El tratamiento dependerá de la extensión de la enfermedad, incluyendo reducción del tratamiento inmunosupresor, radioterapia, cirugía y más recientemente el uso de anticuerpos monoclonales anti CD20. Presentamos el caso clínico de una mujer de 67 años, que al octavo mes de recibir un injerto hepático presenta ELDP.

Interacciones farmacológicas en trasplante / Drug interactions in trasplant

Las interacciones farmacológicas representan un problema mayor en el manejo de los pacientes trasplantados. La comprensión de los distintos pasos del metabolismo de estos fármacos permite anticipar y prevenir complicaciones derivadas de su uso. Cada nuevo medicamento introducido en la terapia de estos pacientes debe ser acompañado de una revisión de las interacciones con los inmunosupresores y otros fármacos prescritos.

Drug interactions are a major problem in the management of transplant patients. Understanding the various steps in the metabolism of these drugs allows us to anticipate and prevent complications arising from their use. Each new drug introduced in the therapy of these patients should be followed by a review of interactions with immunosuppressive agents and other drugs prescribed.

Análise clínica evolutiva do uso do tacrolimus como droga imunossupressora em transplante cardíaco pediátrico / Clinical outcome of tacrolimus as maintenance immunosuppressive drug in pediatric heart transplantation

O Tacrolimus é uma potente droga imunossupressora introduzida no transplante cardíaco no início da década de 90. Pacientes com rejeição refratária ou intolerância à ciclosporina podem responder à terapia de resgate com o tacrolimus. Os objetivos deste estudo foram: avaliar a evolução clínica das crianças submetidas ao transplante cardíaco que necessitaram da conversão de ciclosporina para tacrolimus por rejeição refratária, tardia ou efeitos adversos de difícil controle; avaliar a incidência de rejeição após a conversão para o tacrolimus e comparar a sobrevida dos pacientes em uso de tacrolimus e ciclosporina. Realizou-se estudo coorte, observacional, prospectivo, em 28 crianças submetidas ao transplante cardíaco no Instituto do Coração do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo e que foram submetidas à conversão da ciclosporina ao tacrolimus, no período de julho de 1999 a dezembro de 2009. Avaliou-se a incidência de episódios de rejeição e a sobrevida após a conversão. Realizou-se, também, a comparação entre os pacientes em uso de tacrolimus e os pacientes que permaneceram em uso de ciclosporina submetidos ao transplante cardíaco no mesmo período. A idade média no momento do transplante foi de 5,3 anos, e no momento da conversão de 8,2 anos. As causas de conversão foram efeitos adversos em 50% dos pacientes, rejeição tardia em 32% e rejeição refratária em 18%. O tempo médio de conversão e seguimento foram 36 meses e 74 meses, respectivamente. Observou-se resolução completa dos episódios de rejeição refratária e melhora dos efeitos adversos em todos os pacientes. A taxa de incidência (x100) de episódios de rejeição antes da conversão foi de 7,98 e após a conversão foi de 2,11 (p=0,0001). A taxa de episódios de infecção antes da conversão foi de 5,89 e após a conversão 4,18 (p=0,023). Pela análise das complicações pré e pós-conversão ao tacrolimus, não se evidenciou diferença estatisticamente significativa em relação...

Tacrolimus is a potent calcineurin inhibitor that was introduced in heart transplantation therapy in the early 1990s. Organ transplant recipients with refractory rejection or intolerance to conventional immunosuppressant may respond to rescue therapy with tacrolimus. The aim of this study was to evaluate the clinical outcome of children undergoing heart transplantation who required conversion from a cyclosporine to a tacrolimus-based immunosuppressive regimen due to refractory rejection, late rejection or cyclosporine intolerance. We performed a prospective observational cohort study in 28 children who underwent cardiac transplantation at the Heart Institute (InCor) University of São Paulo Medical School and who required conversion from July 1999 to December 2009. The clinical outcome of the patients was evaluated after tacrolimus conversion. We also compared the patients on tacrolimus to the patients who remained on cyclosporine, and who had undergone heart transplantation during the same period. The mean age at the time of transplantation was 5.3 years and 8.2 years at the time of conversion. The causes of conversion were adverse side effects in 50% of patients, late rejection in 32% and refractory rejection in 18%. The mean time from heart transplant to conversion was 36 months and the mean follow-up period was 74 months. We observed complete resolution of refractory rejection episodes and adverse side effects in all patients. The incidence rate (x100) of rejection episodes before and after conversion was 7.98 and 2.11, respectively (p = <0.0001). The rate of infectious episodes before conversion was 5.89 and after conversion was 4.18 (p = 0.023). There was no statistically significant difference in relation to tumor, renal failure requiring dialysis, systemic arterial hypertension, dyslipidemia, gallstones, diabetes mellitus, anemia, neurological complications, hirsutism and gingival hyperplasia after conversion. A significant incidence of cardiac...

Rapid recovery of diabetes two months after discontinuation of tacrolimus [FK-506] in a single lung transplant patient

Post-transplant diabetes mellitus [PTDM], developing in almost one quarter of renal transplant patients within three years after the procedure, contributes to post-transplant morbidity and mortality by increasing the risk of infection and cardiovascular events. PTDM is considered a variant of diabetes mellitus [DM] type II and results in similar microvascular and macrovascular diabetic complications seen in non-transplant patients. In this article, we present a case of single lung transplant patient who developed PTDM with a severe DKA as the first manifestation of the disease. PTDM resolved rapidly after discontinuing tacrolimus

Status epilepticus as a presenting sign of reversible posterior leukoencephalopathy syndrome in a liver transplant recipient

Reversible posterior leukoencephalopathy syndrome [RPLE] is an increasingly recognized disorder, most commonly associated with immunosuppressive and cytotoxic agent, malignant hypertension and toxemia of pregnancy. Neurological symptoms are headache, mental and visual disturbance, and seizures. Brain MRI findings are symmetrical bilateral hyper intense areas of occipital and parietal lobes in T2-weighted magnetic resonance [MR] images. This finding is reversible with prompt successful treatment which may take days to weeks for full reversal. We observed a case of status epilepticus which occurred 32 days after liver transplantation in a patient on regimen consisting of Tacrolimus [FK 506]. He had no history of neurologic disease or metabolic abnormalities. Typical findings of RPLE were present on brain MRI. The recurrence of seizures terminated after a few hours with adding Na-valproate to Phenytoin, Phenobarbital and Midazolam. The radiological finding of brain MRI gradually diminished after several weeks. A physician should be alert of seizures during early post transplant period of liver transplantation. He should bear in mind the diagnosis of RPLE and consider discontinuation of immunosuppressive drugs
