    ABSTRACT: Interstitial lung abnormalities have been detected in up to 24% of kidney transplant patients receiving traditional immunosuppressive therapies (eg, cyclosporine, azathioprine); they usually occur early after transplantation and tend to resolve over time. Newer immunosuppressants such as mycophenolic acid and, particularly, mammalian target of rapamycin (mTOR) inhibitors (eg, sirolimus) may cause significant lung toxicity. However, the prevalence and severity of interstitial lung lesions in long-term, stable kidney transplant patients receiving either traditional or newer immunosuppressants is not known.

    ABSTRACT: Central nervous system (CNS) lymphoma is a rare posttransplant lymphoproliferative disorder (PTLD), which usually has a poor outcome. To date, no specific conditions predisposing to this complication have been identified. We here describe the case of a renal transplant patient who was initially diagnosed as having Epstein-Barr virus (EBV)-associated leukoencephalopathy and ultimately developed EBV-positive CNS lymphoma. The patient was a young lady who, 2 years after transplantation, presented with focal neurological and electroencephalographic abnormalities and diffuse white matter lesions on brain magnetic resonance imaging. EBV-DNA was detected in the cerebrospinal fluid (CSF) by polymerase chain reaction. After acyclovir therapy and immunosuppressive drug tapering, the symptoms and electroencephalographic abnormalities subsided, and EBV-DNA disappeared from the CSF. Ten years later, a bulky cerebral mass was found. After excision, a diagnosis of EBV-positive, Hodgkin-like monomorphic B-cell PTLD was made. This case illustrates the potential pathophysiological relationships between EBV infection, leukoencephalopathy and CNS lymphoma; although a long time elapsed from the initial neurological illness to CNS lymphoma, a link between these two conditions cannot be excluded. Therefore, a careful long-term follow-up of EBV-related encephalopathy is advisable.

    ABSTRACT: Diabetes mellitus is one of the major causes of end stage renal disease. After 10-15 years from the onset 30% of diabetic patients present nephropathy, and once haemodialysis is required, morbidity is particularly high and long-term survival is lower than in non-diabetic patients. Currently, it is demonstrated that simultaneous pancreas-kidney transplantation (SPK) shows beneficial effects on patient survival, on some diabetic degenerative complications and on the quality of life. Aim of the work is to report our experience in pancreas transplantation. From June 1998 to June 2005 17 type I diabetic uremic patients underwent SPK. Donor selection considered hemodynamically stable young patients without cardiac arrest or vasopressor drug excess and with a brief Intensive Care Unit hospitalization. Average donor age was 26 years (range 16-38). The cause of death was trauma for 14 donors (82.4%) and spontaneous cerebral hemorrhage for 3 donors (17.6%). Average pancreas cold ischemic time was 716 minutes (range 320-968). No patient mortality was observed. No primary or delayed graft function was observed both for pancreas and kidney. Biopsy proved the occurrence of acute rejection episode in one patient (5.8%). Five surgical (29.4%) and 2 medical (11.7%) complications developed. At a median follow-up of 36.4 months (range 4.2-88) patient survival rate was 100%. Pancreas and kidney graft survival rate was 76.5% and 94.1%, respectively. All patients referred an improvement in their quality of life. SPK represents a well-established therapy for uremic type I diabetes mellitus since it improves patient survival in selected recipients. Our experience, as reported in literature, confirm that a successful pancreas transplantation not only brings the recipient back to normal glycemic levels, but it also improves the patient's quality of life by stabilizing some of the secondary complications of diabetes.

    ABSTRACT: Lymphorrhea is a minor complication after kidney transplantation but may develop into a lymphocele and prolong hospital stay. Treatment is conservative based on percutaneous drainage until lymphatic leakage cessation. It has been reported that octreotide has beneficial effects to treat lymphorrhea after axillary node dissection and excision of lymphatic malformations. The aim of this study was to report preliminary experience about octreotide treatment in lymphorrea after kidney transplantation. This retrospective study included 20 recipients of cadaveric kidney allografts with posttransplant lymphorrhea including 10 treated with instillation of povidone iodate solution, and the other 10 with octreotide (0.1 mg three times a day subcutaneously). We reviewed the daily amount of fluid collection, duration of lymphorrhea, complications, lymphocele formation, rejection episodes, graft outcomes, and hospital stay. The average duration of lymphorrhea was 8.5 (+/-4.5) and 16.3 (+/-7.3) days for the octreotide versus the povidone groups, respectively (P = .001). No complications occurred among the octreotide group, while three lymphoceles grew among patients treated with povidone solution. No differences were observed for acute rejection episodes or renal function between the groups. No octreotide-related adverse events were noted. The mean length of lymphorrhea was lower with octreotide versus iodate povidone solution treatment. There was a shorter hospital stay and minor patient discomfort. In conclusion, lymphatic leakage after kidney transplantation may be successfully managed by octreotide administration.

    ABSTRACT: A short right renal vein may be associated with technical problems in renal transplantation. For this reason, a vena caval extension may be useful to improve exposure of the anastomosis and graft placement. This report evaluates the safety and the effectiveness of renal vein extension, which was routinely performed in right renal transplantation. From April 1986 to December 2002, we performed 371 right kidney transplantations with 252 using the standard technique (group A) and 119 using the renal vein extension (group B). No statistical differences were found between the 2 groups in terms of renal vein thrombosis incidence, delayed graft function, morbidity, and graft loss. Indeed, mean warm ischemia time was reduced in the venoplasty group. In conclusion, renal vein extension is an easy, safe technique that reduces warm ischemia time. We suggest more extensive use of this procedure in right kidney transplantation.

    ABSTRACT: In transplant patients, Kaposi sarcoma (KS)-associated herpesvirus or human herpesvirus-8 (HHV-8) infection is associated with the development of KS, primary effusion lymphoma and Castleman disease. Whether HHV-8 is either reactivated in the recipient or transmitted by the donor has been investigated so far only by serologic studies. Thus, we addressed the issue of HHV-8 transmission in the transplantation setting by molecular methods. We exploited the high level variability of the orf-K1 gene and the polymorphism of the orf-73 gene of the HHV-8 genome to assess the genetic relatedness of the HHV-8 strains identified in the posttransplant KS lesions that developed, simultaneously, 20 months after transplantation, in 2 recipients of twin kidneys from the same cadaver donor. The 100% identity of nucleotide sequence of the most variable viral region and the presence of the same, single orf-73 type in both patients provides strong molecular evidence of organ-related transmission of HHV-8 in the setting of transplantation.

    ABSTRACT: A patient is described in whom a recurrence of vasculitis was observed in the kidney allograft six years after transplantation and one year after withdrawal of corticosteroid therapy. This case shows that systemic vasculitis may recur at any time after transplantation which implies a continuous and careful monitoring of these patients.

    ABSTRACT: Among diagnostic postoperative procedures in renal cadaver transplantation echographic examination shows high sensitivity and specificity (over 80%). Urographic examination is in fact often dangerous and impossible in non-functioning grafts. Echography can reveal several liquid and solid collections such as hematomas, urinomas, abscesses, lymphatic collections and so on. Urinary obstructions caused by ureteral clots, calculi, external masses can be also detected through echographic examination. Vascular complications can be evaluated through echo and US Doppler examination showing arterial and venous complications. In most of cases acute and chronic graft rejection can be revealed through echo examination whereas in few cases diagnosis can be made only with the help of renal biopsy, laboratory findings and clinical conditions. In conclusion echography is a safe and reliable procedure in renal graft postoperative monitoring.

    ABSTRACT: The clinical experience obtained with 2 hours every other day recirculation dialysis, using 20-40 liters of dialysate, without sorbents, and standard cuprophane dialyzers of 1.0-1.5 sq.mt. is reported. So far, over 350 treatments in 8 patients have been performed. After 2 hours of treatment the removal of urea, creatinine, phosphate and uric acid, is similar to that obtained by 4-6 hours of haemofiltration. The alkalinazation of the patient through direct venous infusion of bicarbonate, makes predialysis acid-base significantly better than in standard haemodialysis and haemofiltration. Asymptomatic correction of severe fluid overload is easily obtained like in isolated ultrafiltration. The role of osmolality and vasopressors are discussed. A dry weight below the value obtained by previous dialysis treatment is achieved, and volume dependent hypertensions as in haemofiltration are corrected after 2-8 weeks. As an additional advantage, this method offers a highly semplified technical approach and a further reduction of the dialysis time.

    ABSTRACT: Low serum iron level with a transferrin saturation below 16% is a crucial aetiologic factor of anaemia in haemodialysed patients. Current therapy usually is a correct dialytic and dietetic treatment and i.v. iron supply. Two groups of haemodialysis patients with low serum iron but a normal transferrin saturation, have been studied by comparing the efficacy of the i.v. and the oral iron supply. The serum iron of the two groups changed from low to normal level with highly significant difference. Haemoglobin and haematocrit did not change because of the normal transferrin saturation before the treatment. In conclusion, in uraemic patients treated by chronic dialysis, the oral and the i.v. iron therapy probably give the same result.

    ABSTRACT: One hundred and one patients were treated for up to two years for three hours every other day (10.5 hr/week), or four hours thrice-weekly with conventional disposable 1m2 dialysers have been investigated. Rigorous control of water balance and the maintenance of predialysis serum K and PO4 within normal limits were the main criteria for judging the adequacy of the treatment. The results regarding blood pressure, phosphate problems, haematocrit, peripheral nerve status, pericarditis and range of rehabilitation are discussed.

    ABSTRACT: The results regarding the treatment of 55 patients, 6 of them treated for, at least 10 months, with 1 sq. meter disposable dialyzers and a dialysis strategy of 3 hours every other day or 4 hours trice weekly have been presented. Clinical indexes especially regarding erythropoiesis and peripheral nerve status will be discussed. Th results show that this new method of treatment is feasible and may become in the future a routine strategy for chronic intermittent dialysis.
