Previous issue date: 2016-03-22 / Introduction: Even though kidney transplant represents a new perspective to
individuals with chronical kidney disease due to its correlation with a better quality of
life results and morbimortality indexes, the procedure itself is not free of risks.
Vascular complications rates around the world varies from 1 – 23% and it is are also
associated with a high risk of kidney graft losses. Objective: To evaluate the
incidence of vascular complications among patients submitted to kidney transplant at
Santa Casa de Misericórdia de Goiânia on a period of time between January 2013 to
December 2014. Material and Methods: It was analyzed 35 files from patients
submitted to kidney transplant at Santa Casa de Misericórdia de Goiânia on a period
of time between January 2013 and December 2014. It was analyzed the following
variables: renal artery stenosis, renal artery thrombosis, renal vein stenosis, renal
vein thrombosis, renal artery pseudoaneurysm, arteriovenous fistula, renal artery
kinking, kidney graft torsion and kidney infarction. It was also collected data for:
kidney graft side, donator´s aspects (alive or deceased), receptor´s age, receptor´s
gender, necessity for reintervention and cold ischemia time. Results: It was included
32 patients, 34,38% females and 65,62% males, with median age of 46 years old.
Among all surgical complications it was found 3 events of urinary leakage (9,3%), 2
events of retroperitoneal abscess (6,25%), 1 event of kidney graft torsion (3,12%)
and 1 event of arterial stenosis (3,12%). All kidney grafts came from deceased
donators (100%) and there were no graft losses. Conclusion: Even though the
following study had shown a low incidence of vascular complications related with
kidney transplant, the TIF more than 24 hours was the only independent risk factor
associated with this event. / Introdução: Embora o transplante renal represente uma perspectiva ao
indivíduo portador de doença renal crônica terminal por se correlacionar a melhores
índices de qualidade de vida e de morbimortalidade, este procedimento não é isento
de riscos. As taxas de complicações vasculares variam em todo mundo de 1 – 23%
e guardam importância por estar associadas a elevado risco de perda do enxerto.
Objetivo: Avaliar a incidência de complicação vascular em pacientes submetidos a
transplante renal na Santa Casa de Misericórdia de Goiânia no período entre janeiro
de 2013 a dezembro de 2014. Material e Métodos: Foram analisados 35 prontuários
de pacientes submetidos a transplante renal na Santa Casa de Misericórdia de
Goiânia no período de Janeiro de 2013 a Dezembro de 2014. Foram analisadas as
seguintes variáveis: estenose de artéria renal, trombose de artéria renal, estenose
de veia renal, trombose de veia renal, pseudoaneurisma de artéria renal, fístula
arteriovenosa, kinking de artéria renal, torção de enxerto e infarto. Foi coletado em
prontuário: rim transplantado, tipo de doador, idade do receptor, gênero do receptor,
reinternação, tempo de isquemia fria. Resultados: A população estudada incluiu 32
pacientes, sendo 34,38% do sexo feminino e 65,62% do sexo masculino, com média
de idade de 46 anos. Entre as complicações cirúrgicas, ocorreram 3 casos de fistula
urinária (9,3%), 2 casos de coleção (6,25%), 1 caso de torção de enxerto (3,12%) e
1 caso de estenose arterial (3,12%). Todos os enxertos (100%) foram de doador
falecido e não houve perda de enxerto em nenhum caso (0%). Conclusões: Embora
o presente estudo tenha observado uma baixa incidência de complicação vascular
relacionada a transplante renal, o TIF superior a 24hs foi o único fator de risco
independente associado a tal evento (p=0,034).

"You look very well for a transplant" : autoethnographic narrative and identity in chronic kidney disease, kidney failure and the life post-transplantRichards, Roselee Jayne 03 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: Despite the high prevalence of chronic kidney disease, renal narratives are under-reported.
Much of what is written on kidney failure is written by health care professionals for health care
professionals and about patients. While medical experts and health care practitioners have
one type of knowledge, their patients have another type of knowledge acquired through their
experience of their own condition. From within the disability and patients’ rights movements
urgent calls have been made for the authentic voices of disabled people and patients to be
heard without the mediation of professional lenses. In response to this my dissertation
combines personal and academic writing to explore my own experience of end-stage renal
disease, dialysis, transplantation and the life after transplant.
I have used autoethnography as a methodology. Autoethnography is a relatively new,
somewhat postmodern form of inquiry that developed from the reflexive turn in anthropology
and narrative studies in the latter part of the twentieth century. It is very useful in writing about
the experience of illness and reflecting on illness narratives because, in autoethnographic
writing, the observer and observed, the narrator and narrated, insider and outsider are the
same person. This allows scope for exploring the problematics of representation and for
finding alternatives to already existing ways of telling certain stories.
Engaging with autoethnography’s postmodern aspects has allowed me to conceptualize
experiences that, until I undertook this research, I have never been able to articulate, because
the traditional (static) illness narrative forms did not speak to my experience or my
understanding of my condition. The central issue in my dissertation lies in the question: How
do I tell the story of chronic illness once I have had an organ transplant? Flowing from this are
a number of sub-issues: Can my story change? How do I describe myself: The well, the ill, the
impaired, the disabled, the afflicted? Do I describe myself living in no man’s land? In my
narrative, do I oscillate between being well and ill, or do I occupy another territory entirely?
And if I do, what is it?
My study shows that writing the story (or stories) of chronic kidney disease is complex,
nuanced and dynamic and that, far from being an extended liminal experience, kidney disease
is littoral. This distinction is important in coming to narrative terms with an identity that is not
damaged so much as different.
Through this I hope to demonstrate to both outsiders and insiders, who often submit to
narratives that are forced on them, that more satisfying alternatives can be found. / AFRIKAANSE OPSOMMING: Ondanks die hoë voorkomssyfer van chroniese nierkwale word nierverhale nie genoeg
aangemeld nie. Die meerderheid van dit wat oor nierversaking geskryf word, word deur
gesondheidsorgdeskundiges vir gesondheidsorgdeskundiges en oor pasiënte geskryf. Terwyl
mediese deskundiges en gesondheidsorgpraktisyns een soort kennis het, het hulle pasiënte ’n
ander soort kennis op grond van hulle ervaring van hulle eie toestande. Van binne die
gestremdheid en pasiënteregte-bewegings het ’n dringende oproep weerklink vir die
outentieke stemme van mense met gestremdhede en pasiënte om gehoor te word sonder die
tussenkoms van professionele perspektiewe. In reaksie hierop kombineer my verhandeling
persoonlike en akademiese beskrywings om my eie ervaring van eindstadium- nierkwale,
dialise, oorplanting en die lewe na oorplanting te verken. Ek het outo-etnografie as metodologie gebruik. Outo-etnografie is ’n relatief nuwe, ietwat
postmoderne vorm van ondersoek wat in die tweede deel van die twintigste eeu uit die
refleksiewe wending in antropologie en narratiewe studies ontwikkel het. Dit is baie bruikbaar
wanneer oor die belewenis van siekte en besinning oor siekte-narratiewe geskryf word
aangesien die waarnemer en die waargeneemde, die verteller en dit wat vertel word, die
ingewyde en die buitestander in outo-etnografiese skryfwerk dieselfde persoon is. Dit laat
meer ruimte vir verkenning van die problematiek van voorstelling en vir die opspoor van
alternatiewe vir reeds bestaande wyses om sekere stories te vertel.
My bemoeienis met postmoderne aspekte van outo-etnografie het dit vir my moontlik gemaak
om ervaringe wat ek tot en met hierdie navorsing nooit kon artikuleer nie, te konseptualiseer,
aangesien die tradisionele (statiese) vorme van siekte-narratiewe nie tot my ervaring of my
begrip van my toestand gespreek het nie. ‘Hoe vertel ek die storie van chroniese siekte nadat
ek ’n orgaanoorplanting gehad het?’ is ’n sentrale vraagstuk in my verhandeling. Hieruit spruit
’n aantal newevraagstukke voort: Kan my storie verander? Hoe beskryf ek myself: Die
gesonde persoon, die sieke, die verswakte, die gestremde, die aangetaste? Hoe beskryf ek
myself wat in ’n niemandsland woon? Fluktueer ek in my narratief tussen gesond wees en siek
wees of betrek ek ’n geheel ander gebied? En indien wel, wat is dit?
My studie toon dat, om die storie (of stories) van chroniese niersiekte te skryf, kompleks,
genuanseerd en dinamies is en dat niersiekte glad nie ’n uitgebreide liminale ervaring is nie,
maar eerder littoraal is. Dit is belangrik wanneer daar tot ’n narratiewe verstandhouding gekom
moet word met ’n identiteit wat nie soseer beskadig is nie, maar eerder anders.
Hierdeur hoop ek om aan beide buitestanders en ingewydes, wat dikwels voor narratiewe wat
op hulle afgedwing word, moet buig, te wys dat daar meer bevredigende alternatiewe gekry
kan word.

Análise do nível sangüíneo ideal de ciclosporina no pós-transplante renal precoce / Identifying cyclosporin optimal blood levels in early renal transplantationBritto, Zita Maria Leme 06 May 2004 (has links)
Níveis sangüíneos de ciclosporina A (CSA) que minimizam a rejeição celular aguda (RCA) no transplante renal com o menor efeito tóxico vêm sendo o alvo de recentes pesquisas. A escolha de terapia imunossupressora com várias drogas permite o uso de doses mais baixas e com menores efeitos colaterais. Níveis de CSA necessários para evitar RCA podem variar com diferentes esquemas terapêuticos. Este estudo prospectivo realizado em um único centro avaliou a eficácia e segurança de dois diferentes níveis sangüíneos de CSA através da área sob a curva de doze horas (AUC 0-12). Cinqüenta e oito receptores de transplante renal foram randomizados para dois grupos, 25 para o grupo AUC0-12 alta (9000-11000 ng.h/mL) e 33 para o grupo AUC0-12 baixa (5000-7000 ng.h/mL). Após a introdução da CSA, a AUC foi avaliada nos dias 4, 7, 14, 21, 28, 42, 56, 70, 84 e 90. Os grupos foram comparáveis em idade, sexo, cor, tipo de doador, uso de indução e outras drogas imunossupressoras. Não houve diferença estatística na incidência de RCA. Foi realizada análise dos pacientes que apresentaram RCA em comparação com os pacientes livres de RCA. A análise de regressão logística mostrou que é necessária uma AUC 0-12 >- 9500 ng.h/mL com especificidade de 84% e sensibilidade de 76%, AUC 0-4 4000 ng.h/mL com especificidade de 91% e sensibilidade de 84% e C2 (concentração sangüínea na segunda hora pós- 6 dose) com especificidade de 92% e sensibilidade de 84% >- 1450 ng/ml, para predizer ausência de RCA. Quando utilizada terapia de indução, níveis mais baixos de AUC0-12, AUC0-4 e C2 (8160 3636 ng.h/ml, 3146 +- 262 ng.h/ml, 1043 +- 151 ng/mL, respectivamente) foram necessários para evitar RCA, em relação aos pacientes que não rejeitaram e não receberam indução (11072 +- 3809 ng.h/ml, 5403 +- 1782 ng.h/ml e 1816 +- 151ng/mL, respectivamente). Esses dados confirmam a necessidade de altos níves de CSA, na ausencia de indução para prevenção de RCA nos três primeiros meses pós-transplante renal e, o emprego de indução permite que níveis sangüíneos mais baixos de CSA sejam empregados com o intuito de prevenir RCA nos primeiros 90 dias após transplante renal / Multiple-drug therapy allows the use of lower doses with fewer side effects. Cyclosporin A (CSA) levels necessary to avoid rejection may vary with different drug combinations. To address this issue, fifty-eight kidney transplant recipients were randomized into two groups: 25 patients to the twelve-hour area under the curve (AUC0-12) high arm (9000-11000 ng.h/mL) and 33 to the AUC0-12 low arm (5000-7000 ng.h/mL). After CSA introduction, AUC0-12 was measured at days 4, 7, 14, 21, 28, 42, 56, 70, 84, and 90. The two groups were comparable regarding age, gender, race, donor type, induction therapy and other immunosuppressive drugs. There was no significant difference in the rate of acute cellular rejection episodes between the two groups. A retrospective analysis was carried out comparing rejectors to non-rejectors, related to induction therapy status. Logistic regression analysis revealed that an AUC0-12 >- 9000 ng.h/mL or AUC0-4 >-4000ng.h/mL or two-hour post-dose cyclosporin level (C2) of >- 1450 ng/mL predicted a rejection-free course. Lower levels of C2 and AUC 0-4 (1043 +-151 ng/mL and 3146 +- 262ng/mL, respectively) were required in non-rejecting patients when induction therapy was used

Expectativas do paciente renal crônico frente à espera do transplante / Kidney Patient\'s Expectations While waiting for a TransplantOliveira, Nilza Tavares Honorato de 18 December 2007 (has links)
Este trabalho pretende lançar um novo olhar sobre o relacionamento entre as pessoas da equipe de saúde e pacientes com Insuficiência renal crônica. O trabalho com pacientes portadores de doença crônica geralmente contém uma carga mental muito densa para os trabalhadores, que lidam diariamente com questões existenciais, como a dor, o sofrimento e a morte, e questões profissionais, como os sentimentos de frustração e impotência diante da doença. Os pacientes também carregam uma carga psíquica, já que a IRC é uma doença que implica na convivência com a dor, o sofrimento e, às vezes, até a morte, que são questões geradoras de ansiedade e estresse. Por outro lado, a doença pode ser vista como uma oportunidade de crescimento pessoal, tanto do paciente como das pessoas que integram a equipe que o assiste. Assim, este trabalho teve como objetivo investigar as percepções e expectativas dos pacientes com IRC,enquanto aguardam, na fila de espera, por um transplante. Promover o máximo de crescimento e trocas na relação profissional-paciente, valorizando o trabalho como fonte de equilíbrio, satisfação e prazer, podem conduzir à realização pessoal, resgatando a doença como ponto de partida para o crescimento dos pacientes. Para isto, foi realizada uma pesquisa qualitativa, utilizando-se de entrevista e questionário, possibilitando a sugestão de medidas que podem contribuir para a qualidade de trabalho e de vida de profissionais e pacientes. Como resultado destas reflexões, emergem algumas sugestões a serem alcançadas; possibilitar os pacientes a realizarem suas escolhas; discutir amplamente com a sociedade a importância da doação de órgãos para que possa diminuir o número de pacientes na lista de espera e de medidas de suporte social ao mesmo; reivindicar a inserção, no ensino médico, de disciplinas que discutam sobre a doença crônica e oferecer um cuidado integral para os mesmos, isto é, atendendo às dimensões físicas, emocionais, espirituais, sociais e econômicas. / The aim of this study was to look at the relationship between health teams and the patient with chronic kidney failure. Working with chronically sick patients often represents a heavy mental burden for health workers who have to handle existencial issues such as pain, suffering , and death as well as professional issues like frustation and helplessness in face of the disease. Patients also sustain a psychic burden once CKF is a condition that involves coping with pain, suffering, and sometimes death, which are issues that generate anxiety and stress.On the other hand, the disease can be regarded as an opportunity for personal growth both for the patient and the workers assisting them. Therefore, the goal of this study was to investigate CKF patients\' perceptions and expectations while waiting for a transplant. Promoting optimal personal growth and sharing in patient/health worker relationship as well as valueing work as a source satisfaction and pleasure can lead to self-realization, regarding disease as a way to foster the patient\'s growth Therefore, a qualitative study making use of interviews and a questionnaire was conducted. Such format allowed for suggesting measures that could improve the quality of working conditions and life both for patients and health workers. Some suggestions emmerged as a result of this study, such as enabling the patients to make their choices; raising public awareness by discussing the importance of organ donation in order to reduce the number of prospective recipients and actions to provide social support to them; requiring that Medical Schools include subjects that will discuss chronic diseases. Finally, patients should be able to receive thorough assistance targeting their physical, emotional, spiritual, social, and economic dimensions.

Avaliação do desenvolvimento pondero-estatural em pacientes pediátricos submetidos a transplante renal no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo / Evaluation of development weight-height on pediatric patients who suffered kidney transplant at the Clinics Hospital of Ribeirão Preto of Medical School of University of Sao PauloLima, Gilson José de 01 June 2015 (has links)
Introdução: A prevalência de doença renal crônica na faixa etária pediátrica ainda é desconhecida. O tratamento de escolha é o transplante renal, independente da idade. Os principais objetivos do tratamento são a manutenção do desenvolvimento físico, neurológico e esquelético, prevenção da doença do metabolismo mineral e ósseo (DMMO), adequada maturação sexual e da função endócrina. O déficit de crescimento está relacionado com a idade de surgimento da insuficiência renal e ocorre devido à má-nutrição energético-calórica, DMMO e uso de corticoide, além dos efeitos deletérios da anemia, uremia e resistência ao hormônio do crescimento. Causas relacionadas ao paciente como retardo de crescimento intra-uterino e malformações congênitas também estão relacionadas. Objetivos: avaliar o desenvolvimento pondero-estatural dos pacientes pediátricos submetidos a transplante renal no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HC FMRP-USP). Casuística: revisão dos prontuários dos pacientes pediátricos submetidos a transplante renal no HC FMRP-USP e análise do desenvolvimento pondero-estatural comparando os score-z altura para idade e índice de massa corporal (IMC) para idade durante o acompanhamento. As variáveis analisadas foram sexo, faixa etária, uso de Basiliximab, realização ou não de diálise, tipo de transplante realizado (doador falecido ou doador vivo relacionado), hipertensão arterial, dose de manutenção de prednisona. Resultados: foi possível avaliar os dados de 31 pacientes, 10 femininos e 21 masculinos. Ao longo do tempo houve ganho significativo em peso (p< 0,0001) e estatura (p< 0,0001) mas nenhuma das variáveis analisadas mostrou diferença estatisticamente significativa. Houve interação significativa do uso de Basiliximab e da faixa etária sobre o IMC e do uso de Basiliximab, faixa etária e dose de prednisona utilizada sobre a evolução da estatura. A estatura manteve abaixo da média padrão durante todo o acompanhamento e nenhum paciente atingiu a altura final esperada. O IMC estava abaixo da média padrão na ocasião do transplante mas a partir do primeiro ano recuperou e manteve estável em torno do percentil 0. Conclusões: a doença renal crônica na infância compromete o desenvolvimento ponderoestatural dos pacientes afetados. / Introduction: The prevalence of chronic kidney disease in the pediatric age range is still unknown. The treatment of choice is a renal transplant, regardless of age. The main objectives of treatment are the maintenance of physical, neurological and skeletal development, the prevention of renal osteodystrophy, and appropriate sexual and endocrine function maturation. The growth deficit is related to the age at onset of renal failure and is due to energy-calorie malnutrition, to renal osteodystrophy and to corticoid use, in addition to the deleterious effects of anemia, uremia and of resistance to growth hormone. Additional patient-related causes are intrauterine growth retardation and congenital malformations. Objectives: to assess the weight-height development of pediatric patients submitted to renal transplantation at the University Hospital, Faculty of Medicine of Ribeirão Preto, University of São Paulo (HC FMRP-USP). Patients: The medical records of pediatric patients submitted to renal transplantation at HC FMRP-USP were reviewed and weight-height development was analyzed by comparing the zscores for height for age and body mass index (BMI) for age during follow-up. The variables analyzed were: sex, age range, use of Basiliximab, having undergone dialysis or not, type of transplant performed (cadaver donor or related live donor), arterial hypertension, and maintenance dose of prednisone. Results: it was possible to assess the data of 31 patients, 10 girls and 21 boys. A significant weight gain (p<0.0001) and height (p<0.0001) occurred over time but none of the variables analyzed showed a statistically significant difference. There was a significant interaction between age range and BMI, between the use of Basiliximab and age range and between the prednisone dose used and height evolution. Height was below the standard mean value throughout follow-up and no patient reached the expected final height. BMI was below the standard mean value at the time of transplantation, but recovered after the first year and remained stable at a value of about 0. Conclusions: renal failure during childhood compromises the weight-height development of affected patients.

Tacrolimus pharmacogenomics in abdominal solid organ transplantationFalconer, Stuart John January 2018 (has links)
Background: Abdominal solid organ transplantation has evolved from an experimental procedure to a well-established therapy within a few decades. This success is largely due to the introduction of calcineurin inhibitor immunosuppression. Tacrolimus is the most widely used calcineurin inhibitor but has a narrow therapeutic range which requires close drug monitoring to prevent both toxicity and inadequate immunosuppression. Previous studies in renal transplantation have shown that genetic polymorphisms, CYP3A5, CYP3A4*22 and ABCB1 can influence the bioavailability and pharmacokinetics of tacrolimus. These polymorphisms are closely linked to ethnicity and have never been studied in a Scottish population before. Additionally, increasing evidence suggests that high variability of tacrolimus is linked to increased graft loss in kidney transplant patients. Methods: 5889 subjects were genotyped for the genetic polymorphisms CYP3A5 A > G allele transition, CYP3A4*22 C > T and ABCB1 C > T transition. This included 4899 healthy individuals from Generation Scotland bio-resource and 990 patients who underwent renal, liver, or simultaneous pancreas kidney transplants or were organ donors. Tacrolimus dose, trough level and renal function were measured at 11 time points from date of transplant up to and including 12 months post-transplant. Clinical data including episodes of acute rejection, graft and patient survival were compared between the different genotypes. Separate analyses were undertaken for kidney, SPK transplants, as well as liver transplants, the latter looking at recipient and liver donor genotype. A separate cohort of 103 renal transplant patients converted from twice-daily to once-daily tacrolimus had their tacrolimus variability calculated and compared with graft survival. Results: The distribution of the 3 different genotypes of CYP3A5, CYP3A4*22 and ABCB1 were comparable with other Caucasian populations studied previously. In renal transplant recipient expression of the A allele (GA/AA) led to significantly increased dose requirements of tacrolimus and initially lower tacrolimus trough levels. The different genotypes of ABCB1 had no effect. Expression of a CYP3A4*22 T allele trended towards a lower tacrolimus dose requirement but this was not significant. There was no difference in renal function, graft survival or patient survival with any of the polymorphisms. SPK patients had comparable results. In the liver transplant patients, the donor genotype had a greater influence than the recipient one. The donors with CYP3A5 A allele expression had significantly higher tacrolimus dose requirements and lower initial tacrolimus levels. This was apparent to a lesser extent with the recipient expression of CYP3A5 and did not reach statistical significance at all time points. There was no significant difference in tacrolimus dose requirements or level with either donor or recipient expression of ABCB1 or CYP3A4*22. There was a significantly higher incidence of acute rejection in donor CYP3A5 A allele expressers of liver transplant patients in univariate and multivariate analysis. There was no significant different in acute rejection with ABCB1 or CYP3A4*22 genotype. No differences in graft or patient survival with either donor or recipient genotype of any of the 3 polymorphisms were noted. Conversion from twice-daily to once-daily tacrolimus in the first 12 months post-transplant reduced tacrolimus variability. Patients with high tacrolimus variability pre and post conversion had significantly greater graft loss than patients with low tacrolimus variability. Conclusion: CYP3A5 expression results in increased tacrolimus requirements to achieve adequate immunosuppression in renal transplant and SPK patients. Donor rather than recipient CYP3A5 expression is relevant for liver transplantation and dose requirements. There may be an association with donor CYP3A5 expression in liver transplant patients and acute rejection which needs further evaluation. ABCB1 and CYP3A4*22 do not appear to have a significant impact in any of the organ transplants. High tacrolimus variability is associated increased graft loss in renal transplant patients.

AvaliaÃÃo da FunÃÃo Sexual e Reprodutiva de Homens em HemodiÃlise e Transplantados Renais (Estudo Piloto) / Evaluation of the Sexual and Reproductive Function of Men in HemodiÃlise and Transplantados Renais (Study Pilot)LeocÃcio Venicius de Sousa Barroso 31 July 2007 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Temos por objetivo avaliar a funÃÃo sexual e testicular (endÃcrina e espermÃtica) de homens em hemodiÃlise e transplantados renais. O estudo compreende 22 pacientes renais crÃnicos em hemodiÃlise e 21 pacientes transplantados renais acompanhados no ambulatÃrio de prà e pÃs-transplante do Hospital UniversitÃrio Walter CantÃdio, UFC. Os pacientes foram submetidos a anamnese, exame fÃsico e avaliados atravÃs de questionÃrio de avaliaÃÃo sexual. A avaliaÃÃo endÃcrina foi feita atravÃs dos seguintes hormÃnios: FSH, LH, Prolactina e Testosterona. AnÃlise seminal (espermograma) e testes de funÃÃo espermÃtica (teste hipo-osmÃtico, teste de estabilizaÃÃo da cromatina nuclear e swim-up) foram realizados. As medianas dos escores dos grupos controle, hemodiÃlise, transplante, foram, respectivamente, na funÃÃo erÃtil 29/27, 5/28; funÃÃo orgÃstica 10/10/10, funÃÃo desejo sexual 10/8/9, satisfaÃÃo com a relaÃÃo sexual 13/11/12, satisfaÃÃo com a vida sexual 10/10/9, evidenciando que nÃo houve diferenÃa estatisticamente significante entre os grupos, exceto no componente desejo sexual em que o grupo hemodiÃlise foi maior que o controle (P = 0,0004). As medianas das concentraÃÃes hormonais, no grupo hemodiÃlise e transplante, foram, respectivamente, prolactina 17,27/11,4; testoterona 5,25/4,78; FSH 3,65/4,11; LH 7,02/5,9; nÃo sendo constatada diferenÃa estatisticamente significante, exceto pelas dosagens de prolactina que foram maiores no grupo hemodiÃlise (P = 0,0035). As mÃdias e desvio-padrÃo dos parÃmetros seminais e testes de funÃÃo espermÃtica nos grupos hemodiÃlise e transplante, foram respectivamente, volume 1,86Â0,85/3Â1,9; pH 8Â0/8,14Â0,24; concentraÃÃo 25,57Â25,7/36,6Â37,5; motilidade progressiva 30,29Â27,5/33Â9,67; vitalidade 40Â16,7/52Â12,2; morfologia 10,14Â6,39/13,67Â11,02; estabilidade da cromatina nuclear (estÃvel) 80Â2,16/82Â3,9; estabilidade da membrana espermÃtica 59,71Â4,61/58,5Â4,76; motilidade progressiva pÃs-capacitaÃÃo 48,8Â25,19/40,33Â16,02; concentraÃÃo pÃs-capacitaÃÃo 3,42Â3,7/7,67Â4,18; evidenciando que nÃo houve diferenÃa estatisticamente significante. Conclui-se que o transplante renal nÃo melhora a funÃÃo sexual dos pacientes renais crÃnicos em hemodiÃlise. Houve pouca alteraÃÃo do eixo hipotÃlamo-hipÃfise-gÃnada, em ambos os grupos estudados, porÃm houve melhora dos nÃveis de prolactina sÃrica no grupo transplantado. NÃo hà melhora dos parÃmetros do espermograma padrÃo com o transplante renal, porÃm houve pouca alteraÃÃo nas provas de funÃÃo renal, em ambos os grupos, o que sugere boa previsÃo de fertilidade neste grupo de pacientes estudados. / Our goal is to evaluate the sexual and testicular (endocrine and spermatic) functions on men submitted to hemodialysis and kidney transplants. Our study is based on 22 patients with chronic kidney disease during hemodialysis and 21 kidney transplanted patients attended on a first aid station special for those cases of previous and post transplant at the Hospital UniversitÃrio Walter CantÃdio, UFC. The patients were submitted to anamnesis, physical exams and evaluated through a questionary about sexual performance. The endocrine evaluation was made considering the following hormones: FSH, LH, Prolactin and Testosterone. Semen analysis (spermogram) and sperm functional tests (hypo-osmotic test, nuclear chromatin stabilization test and swim-up test) were made. The median scores of the control, hemodialysis and transplant group were respectively: at erectile function 29/27,5/28, at orgastic function 10/10/10, at sexual desire function 10/8/9, at intercourse satisfaction 13/11/12, at satisfaction related to sexual life 10/10/9 proving that there was no significant statistical difference between the groups â excepting the sexual desire component in which the hemodialysis group was bigger than the control group (P = 0.0004). The hormones concentration averages in the hemodialysis and transplant group were respectively: prolactin 17,27/11,4; testosterone 5,25/4,78; FSH 3,65/4,11; LH 7,02/5,9 and it was not verified any significant statistical difference â excepting the prolactin levels that were higher in the hemodialysis group (P = 0,0035). The average and standard deviation from the semen parameter and sperm functional tests on the hemodialysis and transplant group were respectively: volume 1,86Â0,85/3Â1,9; pH 8Â0/8,14Â0,24; concentration 25,57Â25,7/36,6Â37,5; progressive motility 30,29Â27,5/33Â9,67; vitality 40Â16,7/52Â12,2; morphology 10,14Â6,39/13,67Â11,02; stability of nuclear chromatin (stable) 80Â2,16/82Â3,9; stability of the sperm membrane 59,71Â4,61/58,5Â4,76; progressive motility after capacitation 48,8Â25,19/40,33Â16,02; concentration after capacitation 3,42Â3,7/7,67Â4,18 showing that there was no significant statistical difference. Thus, we can conclude that kidney transplants do not improve the sexual function of patients with cronic kidney disease submitted to hemodialysis. The alteration in hypothalamus-hypophysis-gonad was not significant in both groups studied. However, there was an improvement of the seric prolactin levels on the transplanted group. There was no improvement of the standard spermogram parameter related to kidney transplant, but it was observed a slight alteration concerning the sperm functional tests in both groups that suggests a good forecast of fertility in the group of patients studied.

Avaliação do desenvolvimento pondero-estatural em pacientes pediátricos submetidos a transplante renal no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo / Evaluation of development weight-height on pediatric patients who suffered kidney transplant at the Clinics Hospital of Ribeirão Preto of Medical School of University of Sao PauloGilson José de Lima 01 June 2015 (has links)
Introdução: A prevalência de doença renal crônica na faixa etária pediátrica ainda é desconhecida. O tratamento de escolha é o transplante renal, independente da idade. Os principais objetivos do tratamento são a manutenção do desenvolvimento físico, neurológico e esquelético, prevenção da doença do metabolismo mineral e ósseo (DMMO), adequada maturação sexual e da função endócrina. O déficit de crescimento está relacionado com a idade de surgimento da insuficiência renal e ocorre devido à má-nutrição energético-calórica, DMMO e uso de corticoide, além dos efeitos deletérios da anemia, uremia e resistência ao hormônio do crescimento. Causas relacionadas ao paciente como retardo de crescimento intra-uterino e malformações congênitas também estão relacionadas. Objetivos: avaliar o desenvolvimento pondero-estatural dos pacientes pediátricos submetidos a transplante renal no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HC FMRP-USP). Casuística: revisão dos prontuários dos pacientes pediátricos submetidos a transplante renal no HC FMRP-USP e análise do desenvolvimento pondero-estatural comparando os score-z altura para idade e índice de massa corporal (IMC) para idade durante o acompanhamento. As variáveis analisadas foram sexo, faixa etária, uso de Basiliximab, realização ou não de diálise, tipo de transplante realizado (doador falecido ou doador vivo relacionado), hipertensão arterial, dose de manutenção de prednisona. Resultados: foi possível avaliar os dados de 31 pacientes, 10 femininos e 21 masculinos. Ao longo do tempo houve ganho significativo em peso (p< 0,0001) e estatura (p< 0,0001) mas nenhuma das variáveis analisadas mostrou diferença estatisticamente significativa. Houve interação significativa do uso de Basiliximab e da faixa etária sobre o IMC e do uso de Basiliximab, faixa etária e dose de prednisona utilizada sobre a evolução da estatura. A estatura manteve abaixo da média padrão durante todo o acompanhamento e nenhum paciente atingiu a altura final esperada. O IMC estava abaixo da média padrão na ocasião do transplante mas a partir do primeiro ano recuperou e manteve estável em torno do percentil 0. Conclusões: a doença renal crônica na infância compromete o desenvolvimento ponderoestatural dos pacientes afetados. / Introduction: The prevalence of chronic kidney disease in the pediatric age range is still unknown. The treatment of choice is a renal transplant, regardless of age. The main objectives of treatment are the maintenance of physical, neurological and skeletal development, the prevention of renal osteodystrophy, and appropriate sexual and endocrine function maturation. The growth deficit is related to the age at onset of renal failure and is due to energy-calorie malnutrition, to renal osteodystrophy and to corticoid use, in addition to the deleterious effects of anemia, uremia and of resistance to growth hormone. Additional patient-related causes are intrauterine growth retardation and congenital malformations. Objectives: to assess the weight-height development of pediatric patients submitted to renal transplantation at the University Hospital, Faculty of Medicine of Ribeirão Preto, University of São Paulo (HC FMRP-USP). Patients: The medical records of pediatric patients submitted to renal transplantation at HC FMRP-USP were reviewed and weight-height development was analyzed by comparing the zscores for height for age and body mass index (BMI) for age during follow-up. The variables analyzed were: sex, age range, use of Basiliximab, having undergone dialysis or not, type of transplant performed (cadaver donor or related live donor), arterial hypertension, and maintenance dose of prednisone. Results: it was possible to assess the data of 31 patients, 10 girls and 21 boys. A significant weight gain (p<0.0001) and height (p<0.0001) occurred over time but none of the variables analyzed showed a statistically significant difference. There was a significant interaction between age range and BMI, between the use of Basiliximab and age range and between the prednisone dose used and height evolution. Height was below the standard mean value throughout follow-up and no patient reached the expected final height. BMI was below the standard mean value at the time of transplantation, but recovered after the first year and remained stable at a value of about 0. Conclusions: renal failure during childhood compromises the weight-height development of affected patients.
