Concordancia de presión sistólica pulmonar estimada por ultrasonografía y cateterismo cardíaco derecho en pacientes candidatos a trasplante cardíaco

Introducción: A los pacientes con Insuficiencia Cardíaca (IC) estadio D candidatos a trasplante cardiaco se les realiza la determinación de las presiones de la arteria pulmonar por CCD considerada como prueba de oro. Se decidió conocer si la medición de las presión de la arteria pulmonar obtenidas por ECO TT tenían concordancia con las obtenidas por el CCDen estos paciente que fueron evaluados para trasplante cardiaco. Metodología: Se realizó una recolección retrospectiva de los datos consignados en las historias clínicas de todos los pacientes que fueron receptores de un trasplante cardiaco en la FCI-IC desde septiembre del 2005 hasta Mayo del 2013 y se determinó la concordancia entre la presión sistólica pulmonar evaluado por ECO TT y CCD. Resultados: Se incluyeron 46 pacientes. El 76,1% son hombres y con edad promedio de 46,4 ± 13,1. La PSAP estimada por CCD fue 48,3 ± 13,1 mmHg Vs 45,1 ± 12,1 mmHg por ECO TT. La fracción de eyección fue 15,1 ± 4,06% (IC: 13,95-16,36). El 75,9% de los pacientes tenían HTP moderada y severa. La concordancia entre la PSAP determinada por ambos métodos fue 0,475 (I,C: 0.256 - 0.694), y el coeficiente de correlación intraclase fue de 0,090, indicando una baja concordancia entre los dos métodos. Discusión: La determinación de las presiones pulmonares determinada por ECO TT tiene mala concordancia con las obtenidas por CCD. No se debe usar este estudio para excluir los pacientes candidatos a trasplante cardiaco ni para evaluar las variaciones de las misma en la evolución de la enfermedad.

La experiencia de los receptores en el trasplante de órganos y tejidos

El trasplante de órganos y/o tejidos es considerado como una opción terapéutica viable para el tratamiento tanto de enfermedades crónicas o en estadios terminales, como de afectaciones no vitales, pero que generen una disminución en la calidad de vida percibida por el paciente. Este procedimiento, de carácter multidimensional, está compuesto por 3 actores principales: el donante, el órgano/tejido, y el receptor. Si bien un porcentaje significativo de investigaciones y planes de intervención han girado en torno a la dimensión biológica del trasplante, y a la promoción de la donación; el interés por la experiencia psicosocial y la calidad de vida de los receptores en este proceso ha aumentado durante la última década. En relación con esto, la presente monografía se plantea como objetivo general la exploración de la experiencia y los significados construidos por los pacientes trasplantados, a través de una revisión sistemática de la literatura sobre esta temática. Para ello, se plantearon unos objetivos específicos derivados del general, se seleccionaron términos o palabras claves por cada uno de estos, y se realizó una búsqueda en 5 bases de datos para revistas indexadas: Ebsco Host (Academic Search; y Psychology and Behavioral Sciences Collection); Proquest; Pubmed; y Science Direct. A partir de los resultados, se establece que si bien la vivencia de los receptores ha comenzado a ser investigada, aún es necesaria una mayor exploración sobre la experiencia de estos pacientes; exploración que carecería de objetivo si no se hiciera a través de las narrativas o testimonios de los mismos receptores

Factores asociados a diabetes de nuevo inicio en pacientes postrasplante hepático, un estudio de casos y controles

INTRODUCCIÓN: El trasplante hepático ha permitido mejorar la calidad de vida y la supervivencia de los pacientes con cirrosis, se ha identificado un gran espectro de complicaciones crónicas, dentro de las cuales la Diabetes Mellitus de nuevo inicio posterior al trasplante (DMNPT) hace parte y genera un impacto significativo con relación a morbimortalidad. Nuestro objetivo fue determinar los factores asociados para el desarrollo de DMNPT. METODOLOGÍA: Se llevó a cabo un estudio de casos y controles sobre una cohorte histórica donde se revisaron pacientes colombianos postrasplante hepático y se evaluaron factores clínicos asociados con el inicio de DMNPT. RESULTADOS: Se encontró que la incidencia de DMNPT en nuestra población fue de 14.3% (32/224), con una mediana de aparición desde el procedimiento hasta el diagnóstico de 10 meses (IQR 1 - 40). De los 32 casos el 62.5% (20/32) fueron hombres, con una mediana de edad de 55.5 años. La presencia de encefalopatía (ORA 3,55 IC 95% 1.07-8.2), intolerancia a los carbohidratos (ORA 2,97 IC 95% 1.35-9.32) y el tiempo de isquemia (ORA 1.005 IC 95% 1.001 – 1.01) fueron significativamente asociados con el desenlace, en contraste la etiología autoinmune de la cirrosis se comportó como un factor protector (OR 0.34 IC 95% 0.12-091). CONCLUSIÓN: A pesar de las limitaciones del estudio, hay consistencia con resultados previos con respecto a la asociación entre estas variables independientes y el desarrollo de DMNPT, características que se deben tener en cuenta en el seguimiento de este grupo de pacientes estableciendo estrategias de seguimiento rigurosas y terapéuticas tempranas con miras a disminuir el riesgo de progresión a DM.

Respuesta inflamatoria sistémica en el donante como predictor de infección en el primer mes del trasplante renal

Introducción: El objetivo principal de la selección del donante es disminuir la posibilidad de transmisión de enfermedades infecciosas o neoplásicas en el receptor. De forma cruda se calcula que aproximadamente el 50% de los potenciales donantes son contraindicados, la mayoría por infección. La alta demanda de órganos obliga a revalorar las contraindicaciones que hasta hace poco eran absolutas, el reto es diferenciar el SIRS del donante por Muerte Encefálica con el SIRS por infecciones. Método: Estudio de cohorte retrospectivo; que busca evaluar la respuesta inflamatoria sistémica (SIRS) como predictor de infección en pacientes con trasplante renal en el primer mes pos trasplante. Resultados: El contraste de hipótesis proporciono una significancia bilateral (P= 0,071). La pruebas de hipótesis aceptaron la hipótesis nula (P= 0,071), que no existe asociación entre la presencia de SIRS en el donante con la incidencia de infección en el primer mes del pos trasplante renal. La estimación del riesgo de no reingreso por infección al primer mes pos trasplante renal es de 0.881 veces para los donantes con SIRS (IC 0.757 – 1.025). Conclusión: A pesar de no encontrar significancia estadística: el SIRS en el donante no se asocia con un aumento en la incidencia de infección en el primer mes postrasplante. Para encontrar la significancia se propone un estudio con un tamaño de muestra mayor.

Incidencia y factores asociados a infecciones bacterianas en el primer mes postrasplante hepático en la Fundación Cardioinfantil

Introducción: El trasplante hepático ortotópico es la colocación de un nuevo hígado en la misma ubicación del explantado. El objetivo es prolongar la duración y la calidad de vida en pacientes con enfermedades hepáticas terminales. Sin embargo, las infecciones bacterianas son una complicación en los pacientes receptores del trasplante, comprometiendo el éxito del procedimiento. El objetivo fue determinar los factores asociados a infecciones bacterianas en el primer mes tras realizada la intervención y describir las características demográficas de esa población. De 332 trasplantes realizados, que 262 cumplieron criterios para el análisis. Métodos: Se realizó un estudio observacional analítico de casos y controles anidado en una cohorte, en mayores de 18 años, receptores de trasplante hepático primario, de la FCI-IC de 2005 a 2014; excluyendo trasplante combinado hígado riñón, retrasplantes o fallecidos por causa diferente a la infecciosa durante el primer mes. Resultados: Se encontró que la ventilación mecánica por más de 1 día, el catéter venoso central mayor de 3 días son los principales factores de riesgo para infecciones bacterianas. La albúmina mayor de 2,6gr/dl se asoció a menor infección. Los agentes etiológicos predominantes fueron gérmenes gram negativos como E. coli, K. pneumonia y E. cloacae. Mientras que bacteremia, infección urinaria y peritonitis fueron las infecciones más frecuentes. La incidencia de infección bacteriana en esta población fue 24%. Discusión: Se recomienda por tanto extubación antes de 24 horas, uso de catéter central menor de 3 días y limitar el uso del catéter vesical.

Incidencia y factores asociados a infección en el primer año postrasplante cardiaco

Objetivo: Determinar la incidencia de las infecciones en el primer año postrasplante cardiaco y los factores asociados a las infecciones en este periodo. Materiales y métodos: Estudio analítico de casos y controles anidados en una cohorte, con los pacientes trasplantados cardiacos en la Fundación Cardioinfantil – Instituto de cardiología desde el año 2005 hasta el 2015. Se realizaron análisis univariados, análisis bivariado entre las variables del estudio y el desenlace para la selección de las variables para el modelo de regresión logística. Resultados: Se presentó una mediana de 54 años de edad en la cohorte, con mayor proporción de hombres (75,8%) y con predominio de la cardiopatía dilatada como indicación de trasplante. La incidencia de infecciones en el primer año postrasplante fue de 45% (30/66). Se encontró mayor riesgo de infección en los primeros tres meses, del 36.3% (IC 95% 23 – 55), mostrando mayor frecuencia de infecciones pulmonares y en piel. Dentro de los organismos aislados más importantes en los primeros tres meses, se encontraron bacilos gram negativos y Aspergillus spp. En el primer año postrasplante la cardiopatía dilatada con un OR 4.7 IC95% (1.3 – 17) y la enfermedad renal crónica con un OR 6.7 IC 95% (1.4 - 32) se asociaron a la presencia de infecciones. Conclusiones: La frecuencia de infecciones en los pacientes trasplantados cardiacos en la Fundación Cardioinfantil IC es similar a la observada en la literatura. La aparición de infecciones en el primer año postrasplante, se asocia a la presencia de cardiopatía dilatada y enfermedad renal crónica.

Intermittent antegrade cardioplegia: isolated heart preservation with the Asporto heart preservation device

Background—A major problem in procurement of donor hearts is the limited time a donor heart remains viable. After cardiectomy, ischemic hypoxia is the main cause of donor heart degradation. The global myocardial ischemia causes a cascade of oxygen radical formation that cumulates in an elevation in hydrogen ions (decrease in pH), irreversible cellular injury, and potential microvascular changes in perfusion. Objective—To determine the changes of prolonged storage times on donor heart microvasculature and the effects of intermittent antegrade perfusion. Materials and Methods—Using porcine hearts flushed with a Ribosol-based cardioplegic solution, we examined how storage time affects microvascular myocardial perfusion by using contrast-enhanced magnetic resonance imaging at a mean (SD) of 6.1 (0.6) hours (n=13) or 15.6 (0.6) hours (n=11) after cardiectomy. Finally, to determine if administration of cardioplegic solution affects pH and microvascular perfusion, isolated hearts (group 1, n=9) given a single antegrade dose, were compared with hearts (group 2, n=8) given intermittent antegrade cardioplegia (150 mL, every 30 min, 150 mL/min) by a heart preservation device. Khuri pH probes in left and right ventricular tissue continuously measured hydrogen ion levels, and perfusion intensity on magnetic resonance images was plotted against time. Results—Myocardial perfusion measured via magnetic resonance imaging at 6.1 hours was significantly greater than at 15.6 hours (67% vs 30%, P= .00008). In group 1 hearts, the mean (SD) for pH at the end of 6 hours decreased to 6.2 (0.2). In group 2, hearts that received intermittent antegrade cardioplegia, pH at the end of 6 hours was higher at 6.7 (0.3) (P=.0005). Magnetic resonance imaging showed no significant differences between the 2 groups in contrast enhancement (group 1, 62%; group 2, 40%) or in the wet/dry weight ratio. Conclusion—Intermittent perfusion maintains a significantly higher myocardial pH than does a conventional single antegrade dose. This difference may translate into an improved quality of donor hearts procured for transplantation, allowing longer distance procurement, tissue matching, improved outcomes for transplant recipients, and ideally a decrease in transplant-related costs.

Factors associated with health-related quality of life after successful kidney transplantation: a population-based study

Kidney transplantation improves the quality of life of end-stage renal disease patients. The quality of life benefits, however, pertain to patients on average, not to all transplant recipients. The aim of this study was to identify factors associated with health-related quality of life after kidney transplantation. Population-based study with a cross-sectional design was carried out and quality of life was assessed by SF-36 Health Survey Version 1. A multivariate linear regression model was constructed with sociodemographic, clinical and laboratory data as independent variables. Two hundred and seventy-two kidney recipients with a functioning graft were analyzed. Hypertension, diabetes, higher serum creatinine and lower hematocrit were independently and significantly associated with lower scores for the SF-36 oblique physical component summary (PCSc). The final regression model explained 11% of the PCSc variance. The scores of oblique mental component summary (MCSc) were worse for females, patients with a lower income, unemployed and patients with a higher serum creatinine. The regression model explained 9% of the MCSc variance. Among the studied variables, comorbidity and graft function were the main factors associated with the PCSc, and sociodemographic variables and graft function were the main determinants of MCSc. Despite comprehensive, the final regression models explained only a little part of the heath-related quality of life variance. Additional factors, such as personal, environmental and clinical ones might influence quality of life perceived by the patients after kidney transplantation.

A Comparative Study of the Frequency of Antibody and Titers Against Human Herpesvirus 8 Latent and Lytic Antigens in ""At-Risk"" Individuals and Among Patients With Kaposi`s Sarcoma

Differences in the prevalence of human herpesvirus 8 (HHV-8) and Kaposi`s sarcoma (KS) have been described, depending on the study population and their geographic origin. A cross-sectional study aimed at detecting the frequency and titers of antibodies against HHV-8 latent and lytic antigens in serum samples from individuals with different risk-factors for HHV-8 infection, as well as predictive marker identification in patients with KS, was conducted. Serum samples were collected from seven groups of individuals: 75 patients with AIDS-KS, 5 with classic KS, 16 with African KS, 495 with HIV/AIDS, 805 patients with chronic kidney disease, 683 handicapped individuals, and 757 health care workers. Samples were evaluated for the presence and titers of HHV-8-specific antibodies to latent and lytic antigens using ""in house"" immunofluorescence assays. The results were analyzed by the Chi-square, Fisher`s exact test, Kruskal-Wallis and/or Mann-Whitney U-tests. The frequencies of HHV-8 antibodies were as follows: 87.5-100% in patients with KS, 20.4% in patients with HIV/AIDS, 18% in patients with chronic kidney disease, 1.6% in handicapped individuals, and 1.1% in health care workers. A greater number of samples were antibody positive to lytic antigens. Elevated titers of antibodies to latent and lytic antigens, mostly among patients with KS, were detected. Using established serological assays, different ""at-risk"" populations for HHV-8 infection/disease were detected in this geographic area, confirming HIV/AIDS and identifying patients with chronic kidney disease as high-risk groups. It is suggested that a longitudinal evaluation of antibody titers in patients with chronic kidney disease be undertaken to confirm their predictive value in the development of KS. J. Med.

Renal transplantation in patients with primary immunoglobulin A nephropathy

Background. Opinions on the clinical course and outcome of renal transplantation in patients with primary immunoglobulin A nephropathy (IgAN) have been controversial.
Methods. We conducted a retrospective single-centre study on 542 kidney transplant recipients over the period 1984–2001. Long-term outcome and factors affecting recurrence in recipients with primary IgAN were analysed.
Results. Seventy-five patients (13.8%) had biopsy-proven IgAN as the cause of renal failure, and their mean duration of follow-up after transplantation was 100 ± 5.8 months. Fourteen (18.7%) of the 75 patients had biopsy-proven recurrent IgAN, diagnosed at 67.7 ± 11 months after transplantation. The risk of recurrence was not associated with HLA DR4 or B35. Graft failure occurred in five (35.7%) of the 14 patients: three due to IgAN and two due to chronic rejection. Three (4.9%) of the 61 patients without recurrent IgAN had graft failure, all due to chronic rejection. Graft survival was similar between living-related and cadaveric/living-unrelated patients (12-year graft survival, 88 and 72%, respectively, P = 0.616). Renal allograft survival within the first 12 years was better in patients with primary IgAN compared with those with other primary diseases (80 vs 51%, P = 0.001). Thereafter, IgAN patients showed an inferior graft survival (74 vs 97% in non-IgAN patients, P = 0.001).
Conclusions. Our data suggested that around one-fifth of patients with primary IgAN developed recurrence by 5 years after transplantation. Recurrent IgA nephropathy in allografts runs an indolent course with favourable outcome in the first 12 years. However, the contribution of recurrent disease to graft loss becomes more significant on long-term follow up.

Impaired muscle Ca2+ and K+ regulation contribute to poor exercise performance post-lung transplantation

Lung transplant recipients (LTx) exhibit marked peripheral limitations to exercise. We investigated whether skeletal muscle Ca2+ and K+ regulation might be abnormal in eight LTx and eight healthy controls. Peak oxygen consumption and arterialized venous plasma [K+] (where brackets denote concentration) were measured during incremental exercise. Vastus lateralis muscle was biopsied at rest and analyzed for sarcoplasmic reticulum Ca2+ release, Ca2+ uptake, and Ca2+-ATPase activity rates; fiber composition; Na+-K+-ATPase (K+-stimulated 3-O-methylfluorescein phosphatase) activity and content ([3H]ouabain binding sites); as well as for [H+] and H+-buffering capacity. Peak oxygen consumption was 47% less in LTx (P < 0.05). LTx had lower Ca2+ release (34%), Ca2+ uptake (31%), and Ca2+-ATPase activity (25%) than controls (P < 0.05), despite their higher type II fiber proportion (LTx, 75.0 ± 5.8%; controls, 43.5 ± 2.1%). Muscle [H+] was elevated in LTx (P < 0.01), but buffering capacity was similar to controls. Muscle 3-O-methylfluorescein phosphatase activity was 31% higher in LTx (P < 0.05), but [3H]ouabain binding content did not differ significantly. However, during exercise, the rise in plasma [K+]-to-work ratio was 2.6-fold greater in LTx (P < 0.05), indicating impaired K+ regulation. Thus grossly subnormal muscle calcium regulation, with impaired potassium regulation, may contribute to poor muscular performance in LTx.

Medicine non-adherence in kidney transplantation

Background: The increasing prevalence of chronic kidney disease, the relative shortage of kidney donors and the economic- and health-related costs of kidney transplant rejection make the prevention of adverse outcomes following transplantation a healthcare imperative. Although strict adherence to immunosuppressant medicine regimens is key to preventing kidney rejection, evidence suggests that adherence is sub-optimal. Strategies need to be developed to help recipients of kidney transplants adhere to their prescribed medicines. Findings: This review has found that a number of factors contribute to poor adherence, for example, attitudes towards medicine taking and forgetfulness. Few investigations have been conducted, however, on strategies to enhance medicine adherence in kidney transplant recipients. Strategies that may improve adherence include pharmacist-led interventions (incorporating counselling, medicine reviews and nephrologist liaison) and nurse-led interventions (involving collaboratively working with recipients to understand their routines and offering solutions to improve adherence). Strategies that have shown to have limited effectiveness include supplying medicines free of charge and providing feedback on a participant's medicine adherence without any educational or behavioural interventions. Conclusion: Transplantation is the preferred treatment option for people with end-stage kidney disease. Medicine non-adherence in kidney transplantation increases the risk of rejection, kidney loss and costly treatments. Interventions are needed to help the transplant recipient take all their medicines as prescribed to improve general well-being, medicine safety and reduce healthcare costs. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Nephrologists' management of patient medications in kidney transplantation: results of an online survey

Rationale, aims and objectives: Medication adherence is essential in kidney transplant recipients to reduce the risk of rejection and subsequent allograft loss. The aim of this study was to delineate what 'usual care' entails, in relation to medication management, for adult kidney transplant recipients. Methods: An online survey was developed to explore how nephrologists promote and assess medication adherence, the management of prescriptions, the frequency of clinic appointments and the frequency of clinical screening tests. Nephrologists from all acute kidney transplant units in Victoria, Australia, were invited to participate. Data were collected between May and June 2014. Results: Of 60 nephrologists invited to participate, 22 completed the survey (response rate of 36.6%). Respondents had a mean age of 49.1±10.1 years, with a mean of 20.1±9.9 years working in nephrology and 14 were men. Descriptive analysis of responses showed that nephrologists performed frequent screening for kidney graft dysfunction that may indicate medication non-adherence, maintained regular transplant clinic visits with patients and emphasized the importance of medication education. However, time constraints during consultations impacted on extensive patient education and the long-term medication follow-up support was often delivered by the renal transplant nurse coordinator or pharmacist. Conclusions: This study highlighted that nephrologists took an active approach in the medication management of kidney transplant recipients, which may assist with facilitating long-term graft survival. Ultimately, promoting medication adherence needs to be patient centred, involving an interdisciplinary team of nephrologists, pharmacists and renal transplant nurse coordinators, working together with the patient to establish optimal adherence.

A influência do dano de isquemia/reperfusão na função do enxerto e na evolução clínica pós-operatória imediata em pacientes submetidos a transplante hepático : o papel da biópsia de reperfusão

O transplante hepático é o tratamento de escolha para uma série de doenças terminais agudas e crônicas do fígado. Contudo, sua oferta tem sido restringida pela falta de doadores, o que tem provocado o aumento do número de pacientes em lista de espera. A escassez de órgãos condiciona a aceitação para transplante de enxertos provindos de doadores sem as melhores condições para tal – os chamados doadores marginais. O dano de isquemia/reperfusão (IR) é resultado dos fatores perioperatórios inerentes ao procedimento, incluindo as condições do doador. Quanto pior o doador, pior o órgão transplantado, e maior a possibilidade de desenvolvimento de disfunção primária do enxerto (DPE). DPE comumente é definida pela elevação das enzimas hepáticas. As aminotransferases, entretanto, podem alterar-se por outras complicações que não a lesão de isquemia/reperfusão. A histologia hepática, por sua vez, pode fornecer informações acerca da IR. Com o objetivo de estimar a extensão histológica do dano de preservação (necrose hepatocelular e neutrofilia sinusoidal), correlacioná-la a variáveis bioquímicas (índice de reperfusão: AST + ALT + LDH / 3) e avaliar a sua influência no período pós-operatório imediato (até 7 dias), foi realizado um estudo transversal com análise sistemática de 55 pacientes adultos que receberam seu primeiro enxerto hepático entre Setembro de 1996 e Dezembro de 1999. Foram comparados os fatores de risco relacionados ao doador, ao receptor, ao procedimento cirúrgico e ao período pós-operatório e analisadas as biópsias feitas antes e imediatamente após o procedimento cirúrgico. Houve dano de preservação em todos os pacientes estudados tanto por critérios anatomopatológicos quanto por critérios bioquímicos. Houve associação significativa entre os achados bioquímicos e histológicos (p=0,04; coeficiente gamma=0,49). A extensão da necrose hepatocitária parece ser o dado anatomopatológico isolado que melhor se relaciona ao índice de reperfusão (p=0,05; coeficiente gamma=0,48). Houve associação entre DPE e a histologia hepática (p=0,02). O índice bioquímico associou-se à DPE (p=0,001) e à incidência de insuficiência renal aguda (IRA) (p<0,0001). A mortalidade inicial foi maior nos pacientes com índice de reperfusão grave (p=0,002). O índice de reperfusão foi um fator de risco independente para a função do enxerto (p=0,004) e IRA (0,04). A sobrevida atuarial em 1 ano foi significativamente menor nos pacientes com dano de preservação grave (p=0,003). A análise da biópsia de reperfusão é capaz de detectar o dano de preservação sofrido pelo enxerto e se correlaciona às variáveis bioquímicas em sua estimativa.

Avaliação clínica e microbiológica das condições de saúde oral dos receptores de transplante renal do Hospital Universitário Onofre Lopes, Natal RN

Introduction: The chronic immunosuppression promotes the development of changes in the oral cavity of the kidney transplant recipients (KTR), however with the exception of gingival overgrowth, little is known regarding the prevalence of oral lesions in this population. Objective: To evaluate the prevalence of clinical and microbiological conditions of the oral cavity of the recipients of kidney transplantation and the associated factors. Methods: This was a cross-sectional study which examined 96 clinical KTR and experimental where collected saliva stimulated them to identify Candida sp. Data collection consisted of evaluation stomatologic, socio-demographic, clinical aspects of transplantation, condition of oral hygiene and dental caries, yonder to questions about knowledge of oral alteration after transplantation. Results: Of the total, 66.7% of KTR had some type of oral manifestation. The most common was saburral tongue, followed by gingival overgrowth, with both oral manifestations related to gender and concomitant use of cyclosporine and nifedipine (p <0.05). Tacrolimus showed a protective effect for gingival overgrowth (OR = 0.13). The oral hygiene was associated with saburral tongue(p = 0.03) and severity of gingival overgrowth (p = 0.0001). Oral candidiasis was diagnosed in 17.7% of patients and Candida albicans was isolated most frequently in the saliva of RTR with a colonization of 58.3%. The average DMF-T increased with age. The method of oral hygiene was most used brush and toothpaste to 61.5%. Changes in the oral cavity was seen in 54.2% of KTR, citing as the main growth and gingival ulcers. Instructions for oral hygiene after transplantation were neglected for 61.5% of RTR. Dry mouth and halitosis were reported in 30.2% and 36.5% respectively. Conclusions: More the half of the KTR had at least one injury of the mouth, the immunosuppressive drugs and oral hygiene are associated with these alterations. Prospective cohort studies are needed to elucidate the relationship between oral manifestations and levels of drug and risk of oral manifestations occur over time. The kidney transplant recipients showed to be aware of oral alterations occurred after transplantation and uninformed about the oral hygiene instructions. With regard to hygiene, the incidence of caries was considered high, conditions of risk were identified and improvements in primary attention should be encouraged and reflected in the monitoring of renal transplant
