Abstract: introduction: one of the major obstacles for renal transplantation is the donor shortage versus the increasing number of recipients, being necessary the use of viscera from old age donors. objectives: to know what the use frequency of donors aged 55 or more in our center, the results obtained and the potential main complications. methods: a retrospective and descriptive and of cases-control study was conducted including all transplantations carried out in the "hermanos ameijeiras" clinical surgical hospital from 1984 to 2008, sample was divided into two groups according to donor's age, 55 years or more and under 55. results: use frequency of donors aged 55 was only of the 10,6% of sample, 2,8% for live donor and 12,5% for cadaver, time of cold ischemia and the recipient's age was great in the group where were used old age donors, justifying a more frequent and lasting appearance of complications like the acute tubular necrosis, as well as a low rate of discharge function in this group. the urologic and vascular complications were more frequent and influenced on the lost of transplantations compared to control group. although graft survival was less in present study, in group whose transplantations came from older donors there`s not doubt that if conditions involved in this practice in our institution are improved, the use of old age donors is a valid option.

Abstract: Introducción: Uno de los principales obstáculos para el trasplante renal es la escasez de donantes ante el incremento del número receptores, por lo que se ha requerido la utilización de vísceras provenientes de donantes de edades avanzadas. Objetivos: Conocer cuál es la frecuencia de utilización de los donantes de 55 a os o más en nuestro centro, los resultados logrados y las principales complicaciones que se pueden presentar. Métodos: Estudio descriptivo, retrospectivo y de tipo casos y controles, incluyendo todos los trasplantes realizados en el Hospital "Hermanos Ameijeiras" desde el a o 1984 al 2008, la muestra se separó en 2 grupos según la edad del donante, 55 a os o más y menores de 55. Resultados: La frecuencia de utilización del donantes de 55 a os constituyó solo el 10,6 % de la muestra, 2,8 % para el dador vivo y 12,5 % para el cadáver, el tiempo de isquemia fría y la edad de los receptores fue mayor en el grupo que utilizó los donantes de mayor edad, lo que justifica una más frecuente y duradera aparición de complicaciones como la necrosis tubular aguda, así como menor tasa de función al alta en este grupo. Las complicaciones vasculares y urológicas fueron más frecuentes e influyeron en la pérdida de los trasplantes al compararlas con el grupo control. Aunque la supervivencia del injerto fue menor en este estudio, en el grupo cuyos trasplantes provenían de donantes más a osos, no cabe duda que si se mejoran las condicionales que han envuelto esta práctica en nuestro centro, el empleo de donantes de edad avanzada es una opción válida.

Abstract: diabetes mellitus appearing after renal transplant (prtdm) is a frequent and multifactorial complication; however, it seems to exist an individual predisposition to develop such a disease. a study was conducted in 274 subjects that underwent renal transplantation (rt) from dead donors in “hermanos ameijeiras” surgical clinical hospital to corroborate this hypothesis. it was found a frequency of prtdm of 14.2 %, with a predominance of histocompatibility antigens (hla), a28, 9/ 23.07 %, b8 l7/17.94 %, b18 5/12.82 %, and b27 3/7.5 %, in the patients with prtdm that was statistically significant compared to the control group. a higher incidence of complication was observed in patients requiring rt due to polycystic renal disease l7/21 (33.3 %), and glomerulopathies 9/54 (16.6 %), as well as in those with family history of intolerance to carbon hydrates in 20.5 %, 8/39 of rt with prtdm, and only in 5.9 %, 14/235 of the patients without prtdm. these findings could be indirect signs that prtdm is a genetically inherited complication appearing under the influence of other risk factors for its development

Abstract: introduction: the insulin-resistance syndrome (irs) is a frequent complication in the renal transplantation due to multiple factors. objective: to know which alterations linked to renal transplantation and its treatment are risk factors for appearance of insulin-resistance syndrome. methods: a case-control study was conducted in 81 patients underwent renal transplantation, with a graft survival higher than 1 year and not to be diabetics before implant. two groups were established, one including patients with this syndrome (n=39) according to the atp-iii criteria and another as control (n=42). to detect the risk factors pre-transplantation the following variables were compared: age or receptor, time in dialysis, glycemia figures, cholesterol and triglycerides, body mass index (bmi), infection for hepatitis c and a family history of diabetes and post-transplantation variables included immunosuppressive treatment, dose of steroids at third month post-transplantation, cyclosporine a levels and presence or not of rejection. the pre-transplantation variables were categorized in a suitable way for univariate and multivariate analysis where they were statistically significant, in the univariate study: the largest time in dialysis, the great age of recipient, the high figures of pre-transplantation glycemia, the positive to virus c, body mass index higher than 25 and family history of diabetes, this latter factor was the only with statistic representativeness in multivariate analysis. analyzing the variables linked to immunosuppressive treatment, only we note that patients with this syndrome had statistically mean values of cyclosporine higher than those without this complication. conclusions: the insulin resistance syndrome is developed from the alterations present before transplantation and at the moment of implant with the addition of other during the implant course, mainly the immunosuppressive treatment.
