    Description / Table of Contents: Résumé Vingt-neuf malades atteints d'un diabète de type I et d'une néphropathie diabétique au stade terminal ont bénéficié d'une transplantation pancréatique et rénale. La survie actuarielle à 2 ans des malades a été de 87%, celle du rein greffé de 78%. La survie actuarielle à 1 an et à 2 ans du pancréas greffé a été respectivement de 54% et de 40%. Une amélioration substantielle de la survie du transplant pancréatique s'est manifestée au fil du temps. C'est ainsi que de 1981 à 1983 ou 13 malades furent greffés, le taux de survie à 1 an du pancréas greffé fut de 31% alors que de 1984 à 1985 où 16 malades furent traités, il s'éleva à 75%. Cette amélioration a été attribuée à la réduction du temps de l'ischémie par réfrigération et à l'emploi d'un traitement anticoagulant intensif, ce qui entraîna une réduction sensible de la pancréatite et de la thrombose au niveau du transplant. Chez tous les malades où le pancréas greffé assuma ses fonctions, l'insulinothérapie fut interrompue et le métabolisme du glucose redevint normal. Chez les sujets dont le pancréas greffé survécu longtemps aucune aggravation de la rétinopathie ou de la neuropathie ne fut constatée. En outre, des biopsies rénales pratiquées simultanément chez 2 malades 3 ans après la transplantation ont montré l'absence d'épaississement de la membrane basale glomerulaire fait qui aurait témoigné d'une récidive de la néphropathie diabétique.
    Abstract: Resumen Veintinueve pacientes con diabetes mellitus tipo I y nefropatía terminal fueron sometidos a transplante renal y pancreático combinado. La supervivencia actuarial de los pacientes a 2 años fue de 87% y la supervivencia del transplante renal fue de 78% para la totalidad de la serie. Las tasas actuariales de supervivencia del transplante pancreático a 1 y 2 años fueron de 54% y 40% respectivamente. Una mejoría sustancial en la tasa de supervivencia del injerto ha ocurrido en el transcurso del tiempo. Así, en el primer período de la serie (1981–1983, n = 13) la tasa de supervivencia a 1 año fue de 31%, mientras en el segundo período (1984–1985, n = 16) la tasa fue de 75%. Los mejores resultados se debieron probablemente a la reducción en el tiempo de isquemias en frío y a la adopcion de un tratamiento agresivo de anticoagulación; mediante el uso de estas 2 medidas la incidencia de pancreatitis y de trombosis del injerto fue notoriamente reducida. En todos los pacientes con trnsplantes pancreáticos funcionantes fue descontinuada la terapia con insulina y se logró una homeostasis de la glucosa esencialmente normal. Entre los pacientes en quienes el transplante pancreático ha sobrevivido por un periodo mayor, no se ha demostrado continuación del proceso de retinopatía o de neuropatía. Además, las biopsias de los riñones transplantados simultáneamente en 2 pacientes a los 3 años del transplante no muestran aumento del espesor de la membrana basal del glomérulo que indique recurrencia de la nefropatía diabética.
    Notes: Abstract Twenty-nine patients with type I diabetes mellitus and end-stage diabetic nephropathy were subjected to combined renal and pancreatic transplantation. The 2-year actuarial patient survival rate was 87% and the renal graft survival rate was 78% for the whole series. The 1-year and 2-year actuarial pancreatic graft survival rates were 54% and 40%, respectively. A substantial improvement in the pancreatic graft survival has occurred with time. Thus, in the first part of the series (1981–1983, n = 13), the 1-year pancreatic graft survival was 31%, whereas in the second part of the series (1984–1985, n = 16), the figure was 75%. The improvement in results was probably due to a reduction in the cold ischemia time and the adoption of an aggressive anticoagulant treatment; using these measures the incidences of pancreatitis and graft thrombosis were much reduced. In all patients with functioning pancreatic grafts, insulin therapy was discontinued and an essentially normal glucose homeostasis was achieved. Among the patients whose pancreatic transplant has survived for a longer period, no further deterioration in retinopathy or neuropathy was found. Furthermore, biopsies from the simultaneously transplanted kidneys in 2 patients 3 years after transplantation have failed to show any increase in the thickness of the glomerular basement membrane indicative of a recurrence of diabetic nephropathy.

    Notes: Abstract The effect of different doses of cyclosporin (CyA) on the occurrence of histological lesions in renal allograft biopsies was investigated 2 years after transplantation. Biopsy findings were compared in three different groups of patients. In group 1, patients were immunosuppressed with CyA and prednisolone according to an early, high-dosage schedule (initial CyA dose 15–17.5 g/kg body weight); in group 2, they were treated with a medium CyA dose (initial dose 12 mg/kg), together with prednisolone; and in group 3, patients were given triple drug therapy consisting of low doses of CyA (initial dose 8 mg/kg), together with both azathioprine and prednisolone. Interstitial fibrosis and tubular atrophy were common findings in all groups, and on the basis of all biopsies, no difference could be found between the groups with respect to the relative volume of the renal cortical interstitium, which was used as a quantitative parameter for interstitial fibrosis. Likewise, no difference was found with respect to serum creatinine levels. When grafts, that showed signs of rejection (usually vascular rejection) in the biopsy were excluded (two in group 1, six in group 2, and ten in group 3), the mean interstitial volume was significantly lower in group 3 (triple drug therapy) than in the other groups. The serum creatinine levels were also significantly lower in group 3 than in group 1. Thus, chronic renal lesions could be ameliorated when CyA doses were lowered, but this appeared to entail an increased risk of acute or chronic vascular rejection.

    Notes: Abstract In 1987, three patients received kidney grafts bearing medial fibroplasia at our hospital. Two of the grafts were from a cadaveric donor and one was from a living related donor kidney. The vascular affection was known before transplantation. Only one of the recipients developed stenosis and hypertension. With balloon catheter dilatation, the progressive stenosis of the renal graft artery could, however, be successfully corrected.

    Notes: Abstract In two kidney transplant patients, one of whom had panel-reactive antibodies (PRA) before transplantation, a pretransplant negative donor-recipient crossmatch became positive within the 1st week after transplantation. Simultaneously, good graft function deteriorated to a state of anuria. One patient graft biopsy showed a vascular rejection, whilst the other patient biopsy was unrevealing. Both patients were treated with plasmapheresis and a new immunosuppressive drug, 15-deoxyspergualin (DSG). Plasmapheresis was performed for 6 and 9 days, respectively, and DSG was given for 5 days in a dosage of 6 mg/kg body weight per day. One of the patients received methylprednisolone i.v. in addition. During treatment the crossmatch became negative and has since remained that way. In both patients the graft function was restored. No adverse effects were seen from the treatment, except for a slight leukocytopenia and thrombocytopenia.
