The importance to update the guidelines for the use of genetic testing in noncancer patients in Brazil

The Brazilian National Regulatory Agency for Private Health Insurance and Plans has recently published a technical note defining the criteria for the coverage of genetic testing to diagnose hereditary cancer. In this study we show the case of a patient with a breast lesion and an extensive history of cancer referred to a private service of genetic counseling. The patient met both criteria for hereditary breast and colorectal cancer syndrome screening. Her private insurance denied coverage for genetic testing because she lacks current or previous cancer diagnosis. After she appealed by lawsuit, the court was favorable and the test was performed using next-generation sequencing. A deletion of MLH1 exon 8 was found. We highlight the importance to offer genetic testing using multigene analysis for noncancer patients.

Plataforma de simulação em Repast Simphony para análise da divulgação de novas ideias em mercado

Modelação e simulação baseadas em agentes estão a ganhar cada vez mais importância e adeptos devido à sua flexibilidade e potencialidade em reproduzir comportamentos e estudar um sistema na perspetiva global ou das interações individuais. Neste trabalho, criou-se um sistema baseado em agentes e desenvolvido em Repast Simphony com o objectivo de analisar a difusão de um novo produto ou serviço através de uma rede de potenciais clientes, tentando compreender, assim, como ocorre e quanto tempo demora esta passagem de informação (inovação) com diversas topologias de rede, no contato direto entre pessoas. A simulação baseia-se no conceito da existencia de iniciadores, que são os primeiros consumidores a adotar um produto quando este chega ao mercado e os seguidores, que são os potenciais consumidores que, apesar de terem alguma predisposição para adotar um novo produto, normalmente só o fazem depois de terem sido sujeitos a algum tipo de influência. Com a aplicação criada, simularam-se diversas situações com a finalidade de obter e observar os resultados gerados a partir de definições iniciais diferentes. Com os resultados gerados pelas simulações foram criados gráficos representativos dos diversos cenários. A finalidade prática desta aplicação, poderá ser o seu uso em sala de aula para simulação de casos de estudo e utilização, em casos reais, como ferramenta de apoio à tomada de decisão, das empresas.

A longitudinal study of enterobiasis in three day care centers of Havana City

Pinworm infection was prospectively studied during one year in 469 children attending three day care centers. Each child was examined at six months intervals using up to three perianal swabs with adhesive tape. Those found infected were treated with mebendazole. At the beginning of the study we found a prevalence of 28% that dropped to 13% and 12% in the following study periods. The reinfection rate was twice the incidence rate in both study periods. We also found a small percentage (10%) of the children reinfected in most or all study periods. There was a high correlation between reinfection and perianal itching. Our results add further knowledge to the epidemiology of intestinal parasites in day care centers.

A opinião de crianças em idade pré-escolar sobre os seus pares com deficiência

Este estudo teve como objetivo avaliar o conhecimento, as perceções e a intenção comportamental - as atitudes - das crianças em idade pré-escolar com desenvolvimento típico relativamente aos seus pares com incapacidade ou deficiência. As atitudes das crianças foram avaliadas a partir da observação de fotografias de crianças de três grupos distintos: (1) com incapacidade intelectual, (2) com incapacidade motora e (3) sem incapacidades. Participaram nesta investigação 34 crianças a frequentar o ensino pré-escolar, com mais de 4 anos de idade e com desenvolvimento típico. Os participantes foram selecionados de 4 salas com crianças com Necessidades Adicionais de Suporte (NAS) e 4 sem crianças com NAS. A recolha dos dados foi efetuada através de quatro instrumentos: "Understanding Disability Scale", "Perceived Attributes Scale", "Perceived Capacibilities Scale", "Behavioral Intentions Scale". Os resultados obtidos indicaram a existência de muitas dúvidas sobre o que é a deficiência física e incapacidade intelectual. Relativamente à perceção de atributos e capacidades, verificou-se que existem opiniões mais positivas em relação aos pares com desenvolvimento típico comparativamente aos pares com incapacidades. Ao nível da intenção comportamental, os resultados mostraram que não existem diferenças entre os três grupos, isto é, o facto de os pares terem um desenvolvimento típico ou terem incapacidade intelectual ou deficiência física, não determina a predisposição das crianças para interagirem perante os mesmos. Contrariamente à nossa expectativa, o ambiente educativo (inclusivo vs. nãoinclusivo, isto é, ter ou não na mesma turma colegas com incapacidades ou deficiência) não tem um impacto significativo nas atitudes das crianças

Slipped Capital Femoral Epiphysis. A Report of 4 Cases Occurring in One Family

We describe slipped capital femoral epiphysis in 4 members of a black, obese family, who were all first-degree relatives. The aetiology of slipped capital femoral epiphysis is unknown, although it is thought to be multifactorial. Genetic predisposition and environmental factors have been associated with the condition. A familial incidence with at least two cases in the same family has been reported. In epidemiological studies, this incidence ranges from 3% to 35%. Our cases were investigated in an attempt to find a possible aetiological genetic factor. A genetic predisposition with an autosomal dominant pattern of transmission is suggested, although environmental variables must be considered as provocative factors.

Impact of Donor and Recipient Cytokine Genotypes on Renal Allograft Outcome

Allelic differences in gene promoter or codifying regions have been described to affect regulation of gene expression, consequently increasing or decreasing cytokine production and signal transduction responses to a given stimulus. This observation has been reported for interleukin (IL)-10 (-1082 A/G; -819/-592 CT/CA), transforming growth factor (TGF)-beta (codon 10 C/T, codon 25 G/C), tumor necrosis factor (TNF)-alpha (-308 G/A), TNF-beta (+252 A/G), interferon (IFN)-gamma (+874 T/A), IL-6 (-174 G/C), and IL-4R alpha (+1902 G/A). To evaluate the influence of these cytokine genotypes on the development of acute or chronic rejection, we correlated the genotypes of both kidney graft recipients and cadaver donors with the clinical outcome. Kidney recipients had 5 years follow-up, at least 2 HLA-DRB compatibilities, and a maximum of 25% anti-HLA pretransplantation sensitization. The clinical outcomes were grouped as follows: stable functioning graft (NR, n = 35); acute rejection episodes (AR, n = 31); and chronic rejection (CR, n = 31). The cytokine genotype polymorphisms were defined using PCR-SSP typing. A statistical analysis showed a significant prevalence of recipient IL-10 -819/-592 genotype among CR individuals; whereas among donors, the TGF-beta codon 10 CT genotype was significantly associated with the AR cohort and the IL-6 -174 CC genotype with CR. Other albeit not significant observations included a strong predisposition of recipient TGF-beta codon 10 CT genotype with CR, and TNF-beta 252 AA with AR. A low frequency of TNF-alpha -308 AA genotype also was observed among recipients and donors who showed poor allograft outcomes.

Anti-Tumor Necrosis Factor Alpha-Induced Drug Eruptions: One Patient, More Than a Pattern

Background: Tumor necrosis factor alpha (TNFα) antagonists are effective in treating several immune-inflammatory diseases, including psoriasis and inflammatory bowel disease. The paradoxical and unpredictable induction of psoriasis and psoriasiform skin lesions is a recognized adverse event, although of unclear aetiology. However, histological analysis of these eruptions remains insufficient, yet suggesting that some might constitute a new pattern of adverse drug reaction, rather than true psoriasis. Case report: The authors report the case of a 43-year-old woman with severe recalcitrant Crohn disease who started treatment with infliximab. There was also a personal history of mild plaque psoriasis without clinical expression for the past eight years. She developed a heterogeneous cutaneous eruption of psoriasiform morphology with pustules and crusts after the third infliximab infusion. The histopathological diagnosis was of a Sweet-like dermatosis. The patient was successfully treated with cyclosporine in association with both topical corticosteroid and vitamin D3 analogue. Three weeks after switching to adalimumab a new psoriasiform eruption was observed, histologically compatible with a psoriasiform drug eruption. Despite this, and considering the beneficial effect on the inflammatory bowel disease, it was decided to maintain treatment with adalimumab and to treat through with topicals, with progressive control of skin disease. Discussion: Not much is known about the pathogenesis of psoriasiform eruptions induced by biological therapies, but genetic predisposition and Koebner phenomenon may contribute to it. Histopathology can add new facets to the comprehension of psoriasiform reactions. In fact, histopathologic patterns of such skin lesions appear to be varied, in a clear asymmetry with clinical findings. Conclusion: The sequential identification in the same patient of two clinical and histopathologic patterns of drug reaction to TNFα antagonists is rare. Additionally, to the authors’ knowledge, there is only one other description in literature of a TNFα antagonist-induced Sweet-like dermatosis, emphasizing the singularity of this case report.

Familial Abdominal Aortic Aneurysm Is Associated With More Complications After Endovascular Aneurysm Repair

OBJECTIVE: A familial predisposition to abdominal aortic aneurysms (AAAs) is present in approximately one-fifth of patients. Nevertheless, the clinical implications of a positive family history are not known. We investigated the risk of aneurysm-related complications after endovascular aneurysm repair (EVAR) for patients with and without a positive family history of AAA. METHODS: Patients treated with EVAR for intact AAAs in the Erasmus University Medical Center between 2000 and 2012 were included in the study. Family history was obtained by written questionnaire. Familial AAA (fAAA) was defined as patients having at least one first-degree relative affected with aortic aneurysm. The remaining patients were considered sporadic AAA. Cardiovascular risk factors, aneurysm morphology (aneurysm neck, aneurysm sac, and iliac measurements), and follow-up were obtained prospectively. The primary end point was complications after EVAR, a composite of endoleaks, need for secondary interventions, aneurysm sac growth, acute limb ischemia, and postimplantation rupture. Secondary end points were specific components of the primary end point (presence of endoleak, need for secondary intervention, and aneurysm sac growth), aneurysm neck growth, and overall survival. Kaplan-Meier estimates for the primary end point were calculated and compared using log-rank (Mantel-Cox) test of equality. A Cox-regression model was used to calculate the independent risk of complications associated with fAAA. RESULTS: A total of 255 patients were included in the study (88.6% men; age 72 ± 7 years, median follow-up 3.3 years; interquartile range, 2.2-6.1). A total of 51 patients (20.0%) were classified as fAAA. Patients with fAAA were younger (69 vs 72 years; P = .015) and were less likely to have ever smoked (58.8% vs 73.5%; P = .039). Preoperative aneurysm morphology was similar in both groups. Patients with fAAA had significantly more complications after EVAR (35.3% vs 19.1%; P = .013), with a twofold increased risk (adjusted hazard ratio, 2.1; 95% confidence interval, 1.2-3.7). Secondary interventions (39.2% vs 20.1%; P = .004) and aneurysm sac growth (20.8% vs 9.5%; P = .030) were the most important elements accounting for the difference. Furthermore, a trend toward more type I endoleaks during follow-up was observed (15.6% vs 7.4%; P = .063) and no difference in overall survival. CONCLUSIONS: The current study shows that patients with a familial form of AAA develop more aneurysm-related complications after EVAR, despite similar AAA morphology at baseline. These findings suggest that patients with fAAA form a specific subpopulation and create awareness for a possible increase in the risk of complications after EVAR.

Novel FGFR1 Mutations in Kallmann Syndrome and Normosmic Idiopathic Hypogonadotropic Hypogonadism: Evidence for the Involvement of an Alternatively Spliced Isoform

OBJECTIVE: To determine the prevalence of fibroblast growth factor receptor 1 (FGFR1) mutations and their predicted functional consequences in patients with idiopathic hypogonadotropic hypogonadism (IHH). DESIGN: Cross-sectional study. SETTING: Multicentric. PATIENT(S): Fifty unrelated patients with IHH (21 with Kallmann syndrome and 29 with normosmic IHH). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Patients were screened for mutations in FGFR1. The functional consequences of mutations were predicted by in silico structural and conservation analysis. RESULT(S): Heterozygous FGFR1 mutations were identified in six (12%) kindreds. These consisted of frameshift mutations (p.Pro33-Alafs*17 and p.Tyr654*) and missense mutations in the signal peptide (p.Trp4Cys), in the D1 extracellular domain (p.Ser96Cys) and in the cytoplasmic tyrosine kinase domain (p.Met719Val). A missense mutation was identified in the alternatively spliced exon 8A (p.Ala353Thr) that exclusively affects the D3 extracellular domain of FGFR1 isoform IIIb. Structure-based and sequence-based prediction methods and the absence of these variants in 200 normal controls were all consistent with a critical role for the mutations in the activity of the receptor. Oligogenic inheritance (FGFR1/CHD7/PROKR2) was found in one patient. CONCLUSION(S): Two FGFR1 isoforms, IIIb and IIIc, result from alternative splicing of exons 8A and 8B, respectively. Loss-of-function of isoform IIIc is a cause of IHH, whereas isoform IIIb is thought to be redundant. Ours is the first report of normosmic IHH associated with a mutation in the alternatively spliced exon 8A and suggests that this disorder can be caused by defects in either of the two alternatively spliced FGFR1 isoforms.

Spectrum and Frequency of GJB2 Mutations in a Cohort of 264 Portuguese Nonsyndromic Sensorineural Hearing Loss Patients

OBJECTIVE: To assess the spectrum and prevalence of mutations in the GJB2 gene in Portuguese nonsyndromic sensorineural hearing loss (NSSHL) patients. DESIGN: Sequencing of the coding region, basal promoter, exon 1, and donor splice site of the GJB2 gene; screening for the presence of the two common GJB6 deletions. STUDY SAMPLE: A cohort of 264 Portuguese NSSHL patients. RESULTS: At least one out of 21 different GJB2 variants was identified in 80 (30.2%) of the 264 patients analysed. Two mutant alleles were found in 53 (20%) of these probands, of which 83% (44/53) harboured at least one c.35delG allele. Twenty-seven (10.2%) of the probands harboured only one mutant allele. Subsequent analysis revealed that the GJB6 deletion del(GJB6-D13S1854) was present in at least 7.4% (2/27) of the patients carrying only one mutant GJB2 allele. Overall, one in five (55/264) of the patients were diagnosed as having DFNB1-related NSSHL, of which the vast majority (53/55) harboured only GJB2 mutations. CONCLUSIONS: This study provides clear demonstration that mutations in the GJB2 gene are an important cause of NSSHL in Portugal, thus representing a valuable indicator as regards therapeutical and rehabilitation options, as well as genetic counseling of these patients and their families.

Referenda outcomes and the influence of polls: A social network feedback process

This paper proposes a model to explain the differences between outcomes of referenda and the voting trends suggested by polls. Two main effects are at stake. First, the evolution of the voters' attitudes is conditional on the public information made available to them. Second, the predisposition toward abstention among individuals within each voting group may be different. Our model describes how these two aspects of decision making may interact, showing how publicly available information may amplify the distinct tendency toward abstention between both groups and thus affect the outcome of the referendum.

A lesão de isquémia/reperfusão em transplante hepático: análise genética, morfológica e correlação clínica

RESUMO: O transplante hepático ortotópico é uma terapêutica aceite para casos selecionados de falência hepática terminal. O procedimento tem-­‐se aperfeiçoado, evidenciado pelo aumento da taxa de sobrevida de 30 para 75% aos 5 anos, mas cerca de 13 a 27% dos enxertos desenvolve falência primária (PNF) ou disfunção primária (DF) após o transplante. As consequências são devastadoras para a sobrevida do doente e do enxerto. A sua etiologia é multifactorial, incluindo factores relacionados com o dador e o receptor, tempos de isquémia, agressões cirúrgicas, bem como características anatomopatológicas do enxerto. A lesão de isquémia/reperfusão mantem-­‐se como um factor de risco intra operatório, com implicações directas sobre toda a evolução do transplante : existe uma relação íntima entre a PNF e a DF, a preservação do enxerto, a lesão de isquémia/reperfusão, e a falência do transplante. Além disso, está comprovada evidência que sugere que a lesão de I/R torna um aloenxerto mais vulnerável por aumento da imunogenicidade, aumentando a probabilidade de episódios de rejeição precoce e tardia. Com base na prática clínica quotidiana do CHBPT HCC, estudaram-­‐se 54 casos de transplante hepático, agrupados segundo grupos por alocação do enxerto respectivo: Grupo 1(n=27): dador cadáver para receptor cirrótico, Grupo 2 (n=15): dador cadáver para receptor PAF, Grupo 3 (n=12): dador PAF para receptor cirrótico. Observaram-­‐se as alterações histológicas e moleculares sobre o enxerto até ao final da operação do receptor, e as suas consequências clínicas,avaliando: -­‐ As diferentes capacidades de resistência e cada enxerto à lesão de isquémia/reperfusão. -­‐ As situações em que os factores do receptor se sobrepõem às do enxerto na definição do prognóstico, e vice versa. -­‐ A relevância das lesões histológicas e moleculares precoces no tecido hepático na evolução do enxerto e do receptor. Foram colhidas biópsias por agulha dos 54 enxertos hepáticos,42 provenientes de cadáver com coração batente(morte cerebral) e 12 provenientes de dador vivo com PAF, em três tempos diferentes do processo de colheita e transplante hepático: ­‐ A primeira(T0)antes da clampagem da aorta do dador -­‐ A segunda (T1) no final da isquémia fria -­‐ A terceira (T2) após a reperfusão do enxerto, durante o encerramento da parede abdominal. A estas amostras foi extraído RNA total, convertido em cDNA por transcrição reversa e feita a análise da expressão dos genes da CTLA4, IL-­‐1β, IL-­‐4, IL-­‐6, IL-­‐13, TNF-­‐α, Perforina, Selectina, (SELE), Fas-­‐ligando, Granzima-­‐B, Heme-­‐Oxigenase 1(HO1)e Óxido Nítrico Sintetase(iNOS2A)por PCR quantitativo segundo o método do Ct comparativo, utilizando como referência a expressão dos genes da amostra não-­‐isquémica –T0. Os fragmentos de todas as biópsias foram seccionados, para envio de amostra comparativa para processamento histológico habitual, sem qualquer alteração ao protocolo seguido habitualmente na Unidade de Transplantação do Hospital Curry Cabral. A presença de alguns parâmetros histológicos definidos, como esteatose, necrose, vacuolização, congestão sinusoidal e infiltração neutrofílica, foi registada e contabilizada numa classificação numérica. O seguimento clínico e laboratorial, bem como o acompanhamento de eventuais complicações, foi registado e correlacionado com os dados das colheitas de órgãos e com os dados das biópsias. Foram consideradas as seguintes variáveis, como as mais relevantes e objectivas para a interpretação da evolução clínica, tendo sido comparadas estatisticamente com os dados recolhidos, laboratoriais e clínicos: disfunção do enxerto, 207 pós operatórias, número de internamentos igual ou superior a 2 e rejeição crónica e/ou morte do receptor. Foram identificadas características clínicas menos favoráveis, a considerar, nalgumas circunstâncias: género feminino do receptor (sobretudo associado a enxerto masculino, p=0,077), isquémia fria superior a 500 minutos (p=0,074), isquémia quente superior a 90 minutos (p=0,099). Na análise laboratorial, distinguiram-­‐se duas características histológicas desfavoráveis e irreversíveis, como índice de mau prognóstico: a necrose e a balonização (p=0,029); no painel genético escolhido neste estudo,a expressão basal de IL-­‐1β(p=0,028), de SELE p=0,013)e de FAS-­‐L (p=0,079)relacionaram-­‐se com pior prognóstico. Algumas características protectoras intrínsecas dos enxertos só se revelaram indirectamente, como menor infiltração neutrofílica e maior expressão de HO1 e de iNOS nos enxertos PAF, não tendo sido possível provar uma interferência directa nos resultados clínicos. Não se obteve expressão mensurável de genes anti-­‐ inflamatórios nas biopsias hepáticas processadas neste estudo, como a IL13 e a I 4: assim, com a metodologia utilizada, não foi possível obter um perfil de expressão genética associado a boa evolução clínica. O perfil inverso foi sugerido apenas pela expressão basal dos 3 genes mencionados (FAS-­‐L,IL-­‐1β e SELE)no mesmo painel, com o protocolo seguido neste conjunto de 54 doentes. As características do receptor sobrepuseram-­‐se às do enxerto no caso de: -­‐ diagnóstico de PAF no receptor, que determinou uma maior predisposição para a disfunção do enxerto, o que, por sua vez, determina uma menor sobrevida. No entanto, o diagnóstico de PAF no receptor exibe uma curva de sobrevida mais favorável. -­‐ receptores com um baixo balanço de risco (BAR)definiram características favoráveis para enxertos com níveis baixos e moderados de esteatose, fazendo que esta característica, definida como um risco acrescido, não só não se manifestasse clinicamente,como parecesse um factor favorável. As características do enxerto sobrepuseram-­‐se às do receptor no caso de: -­‐ tempo de isquémia fria superior a 500 minutos -­‐ balonização, necrose, FAS-­‐L,IL-­‐1β e SELE em T0 A integração dos resultados moleculares e morfológicos com a evolução clínica, realça o papel da mobilização precoce de neutrófilos nos desempenhos menos favoráveis do enxerto hepático. -------------ABSTRACT: Orthotopic liver transplantation is na accepted therapeutic procedure for selected cases of terminal liver failure. The procedure has been improved, evidenced by the rise of survival rates from 30 to 70% at 5 years, but 13 to 27% of the liver grafts develops primary non function (PNF) or primary dysfunction (PDF) after transplantation. The consequences are devastating for the survival of the patient and of the graft. Its etiology is multifactorial, including factos related with the donor and with the recipient, ischemic times, surgical aggressions, as well as the histological characteristics of the graft. The ischemia/reperfusion lesion is still an intraoperative risk factor, with direct implications in the whole transplant outcome: there is a close interrelation between PNF and DF, graft preservation, ischemia / reperfusion lesion and graft failure. Beyond his, there is proved evidence that suggests that I/R lesion turns the allograft more vulnerable by increasing its immunogenity, increasing the probability of precocious and late rejection episodes. Based on the daily clinical practice at CHBPT /HCC, 54 cases of hepatic transplantation have been studied, grouped by allocation of each graft: Group (n=27):deceased do nortocirrhotic recipient, Group 2 (n=15): deceased donor to FAP recipient, Group 3 (n=12): FAP living donor to cirrhotic recipient. The histologic and molecular changes in the liver graft were observed until the end of the recipiente operation,together with its clinical consequences, evaluating:-­‐The different capacity of resistance of each graft to the ischemia / reperfusion lesion -­‐ The situations where the recipiente factos overlap the ones of the graft, in the definition of prognosis, and vice versa.-­‐ The relevance of the precocious histologic and molecular lesions of the hepatic tissue in the clinical outcome of the graft and the recipient. Needle biopsies were obtained from 54 liver grafts, 42 deceased brain dead donors and 12 from FAP living donors, at three diferente times of the harvesting and the hepatic transplantation: The first one (T0) before clamping the donor aorta -­‐ The second one (T2) in the end of cold ischemia time -­‐ The third one (T) after the reperfusion of the graft, during the closure of the abdominal wall. Total RNAwas extracted to these samples, converted to cDNA by reverse transcription and the analysis of gene expression was made for CTLA4,IL-­‐1β,IL-­‐4,IL-­‐6,IL-­‐13,TNF-­‐α,Perforin,E Selectin (SELE),Fas-­‐ligand,Granzyme-­‐B,Heme-­‐oxigenase 1 (HO1) and Nitric Oxide Sintetase (iNOS2A) by quantitative PCR, according with the Ct comparative method, using the expression of the non ischemic sample – T0. The fragments of all the biopsies were divided, to send a comparative sample to the usual histologic processement, keeping the same usual protocol at the Transplantation Unit of Curry Cabral Hospital. The presence of some defined histologic parameters, such as steatosis, necrosis, vacuolization, sinusoidal congestion and neutrophilic infiltration, was registered and catalogued in a numeric classification. The clinical and laboratory follow-­‐up, as well as the following of eventual complications, was registered and correlated with the data from organ procurement operations and with the data from the biopsies. The following variables were considered as the most relevant and objective ones, to the interpretation of the clinical evolution, being statistically compared with the clinical and laboratorial collected data: graft dysfunction, post-­‐operative complications, number of readmissions of 2 or more and chronic rejection and /or recipiente death. There were identified some unfavorable clinical characteristics, to be considered under certain circumstances: recipiente female gender (specially associated with malegraft, p=0,077), cold ischemia time of more than 500 minutes (p=0,074), warm ischemia time of more than 90 minutes (p=0,099). In the laboratory analysis, two histologic characteristics were identified as unfavorable and irreversible, associated with bad prognosis: necrosis and balonization (p=0,029); in the gene panel selected in this study, the basal expression of IL-­‐1β (p=0,028), SELE (p=0,013) and FAS-­‐L (p=0,079)were related with worse prognosis.Some intrinsic protective characteristics of the grafts were only indirectly revealed, such as less neutrophilic infiltration and bigger expression of HO1 and iNOS in FAP grafts, being impossible to prove any direct inte ference in the clinical results. A relevant and measurable expression of the anti inflammatory genes IL13 and IL4 was not obtained: with the used methodology, it was impossible to obtain a gene expression profile associated with a favorable clinical outcome.The inverse profile was suggested only by the basal expression of the three mentioned genes (FAS-­‐L, IL-­‐ 1β e SELE) in the same gene panel, according with the followed protocol in this group of 54 patients. The characteristics of the recipient overlapped those from the graft, in the case of :-­‐ FAP diagnosis in the recipient, which determined a bigger predisposition to graft dysfunction, which by itself determines a shorter survival. However, FAP diagnosis in the recipiente depicts a more favorable survival curve. -­‐ Recipients with a low balance risk índex (BAR) defined favorable characteristics to grafts with low and moderate grades of steatosis, making that this characteristic, associated with bad prognosis, looked like a favorable factor, and with no clinical interference. The graft characteristics overlapped those from the receptor in the case of: -­‐ Cold ischemic time more than 500 minutes -­‐ Balonization, necrosis, FAS-­‐L, IL-­‐1β and SELE at T0. The integration of molecular and morphologic results with the clinical evolution, stresses the role of a precocious neutrophils mobilization in the worse outcomes of liver grafts.
