Preliminary report on impact of pretransplant dialysis on early graft function: peritoneal versus hemodialysis.

Delayed graft function and acute renal failure after kidney transplant negatively influence graft outcome. It has been reported that pretransplantation peritoneal dialysis (PD) instead of hemodialysis (HD) correlated with better short-term graft outcome in adult kidney recipients. In this study the impact of PD versus HD was evaluated among pediatric kidney recipients. This study suggested that different forms of dialysis pretransplantation did not affect early graft function among pediatric kidney recipients.

Severe rhabdomyolysis and acute renal failure in a kidney transplant patient treated with tacrolimus and chimaeric CD25 monoclonal antibody.

Recently observations of rhabdomyolysis in patients treated with tacrolimus have been reported. The authors present a kidney transplant patient who had an epileptic seizures, severe rhabdomyolysis, and acute renal failure. The patient was initially immunosuppressed with tacrolimus and chimeric CD25 monoclonal antibody. After intensive therapy with plasmapheresis, CVVH, and dialysis, the patient completely recovered at 11/2 year his serum creatinine is 1.2 mg/dL.

Vesico-ureteral reflux in pediatric kidney transplants: clinical relevance to graft and patient outcome.

From June 1985 to December 1998, 173 pediatric renal transplants were carried out in 170 patients at our center. From this pool, 73 patients (34 males and 39 females) with a follow-up of 48 months were examined. In all patients, ureteroneocystostomy was performed according to the Lich-Grégoire procedure. All patients were treated with cyclosporin A (CsA)-based immunosuppression, including prednisone and sometimes azathioprine (AZA). Six months after transplantation, voiding cystography (VCU) was performed in all patients and reflux was classified from Grade I to Grade IV. The patients were divided into two groups: those with reflux (Group A: 25 patients) and those without (Group B: 48 patients). Grade I reflux was found in four patients, Grade II in seven patients, Grade III in seven patients, and Grade IV in seven patients. All the patients with severe reflux (Grade IV) underwent a corrective surgical procedure. Both groups were examined for immunologic and non-immunologic risk factors and no significant differences were found. Analysis of patient and graft survival rates revealed no statistical differences (NS) between Groups A and B. Mean serum creatinine (mg/dL) was 1.06 +/- 0.28 and 1.12 +/- 0.41 at 4 yr in Groups A and B, respectively (NS). Mean calculated creatinine clearance (cCrC; ml/min) was 76.74 +/- 15.92 and 77.96 +/- 15.66 in Groups A and B, respectively (NS). The analysis was further extended by considering the grade of reflux (I to IV). Again, no significant differences in the above parameters emerged between the reflux sub-groups; only in the Grade IV sub-group was a slight decrease in cCrC detected, although this difference was not statistically significant when compared with the other sub-groups. In conclusion, vesico-ureteral reflux (VUR) does not seem to negatively affect graft function. However, as all severe reflux patients (Grade IV) were surgically corrected, no conclusions can be drawn with regard to the influence of Grade IV reflux on long-term graft function.

Early experience with dual kidney transplantation in adults using expanded donor criteria. Double Kidney Transplant Group (DKG).

Dual transplant of marginal kidneys otherwise not considered for single transplant may give access to an expanded pool of cadaveric organs without exposing recipients to the drawbacks of a limited nephron mass supply. This prospective, case-control study compares adverse events and graft outcome in 24 recipients of two marginal kidneys from donors who were >60 yr old or who had diabetes, hypertension, or non-nephrotic proteinuria (cases), with that of 48 age- and gender-matched control subjects who received single ideal grafts at the same center and were given the same immunosuppressive therapy. Marginal kidneys with no macroscopic abnormalities were selected for the double transplant on the basis of a predefined score of histologic damage. Six-month patient and kidney survival was 100% with both of the procedures. Incidence (20.8% versus 20.8%) and median (range) duration of posttransplant anuria (5 [2 to 12] versus 7 [2 to 13] days) were comparable in cases and control subjects, respectively. Time to normal serum creatinine and mean serum creatinine values at each time visit were comparable as well, but with significantly lower levels in cases compared with control subjects from month 2 to last follow-up (1.56 +/- 0.65 versus 1.74 +/- 0.73 mg/dl, P = 0.04). Diastolic BP values averaged during the entire posttransplant period were significantly lower in cases than in control subjects (83.2 +/- 11.5 versus 85.1 +/- 12.5 mmHg, respectively, P = 0.008). Donor/recipient body weight ratio was the only covariate significantly associated at univariate (P = 0.002) and multivariate (P = 0.001) analysis with last available serum creatinine concentrations. Incidence of acute allograft rejections (20.8% versus 18.8%) and of major surgical complications was comparable in the two groups. No renal artery or vein thrombosis was reported in either group. Dual transplants of marginal kidneys are as safe and tolerated as single transplants, and possibly offer an improved filtration power without exposing the recipient to enhanced risk of delayed renal function recovery, acute allograft rejection, or major surgical complications.

[Renal transplantation in patients over 60 years of age. An increasing clinical reality].

The elevation of the uremic population age, the longer survival of dialysis, the increasing number of elderly donors, together with the safer surgical, anesthesiological and immunological procedures have led all over the word to an improvement of over 60s patients transplantation program, with very good results. The authors present their own experience of renal transplantation in elderly recipients and a review of what is reported in the literature on the question.

[Pregnancy in women undergoing a kidney transplant. Our experience and a review of the literature].

The chances of pregnancy for uremic women are usually very low, because of hormonal balance changes which determine a strong reduction in fertility. Epidemiological studies reveal that pregnancy in hemodialyzed women in fertile patients 4.6-6 months after a well functioning kidney transplant, one fertile transplanted woman over 50 can become pregnant. In the first transplant era, pregnancy after kidney transplant was considered "a big hazard", especially because of the possible side-effects of immunosuppression drugs on foetus development, and the risk of a worsening in the mother's renal function. Therefore, women were strongly recommended to avoid pregnancy. More recently, several reported papers have shown that pregnancy can be safely carried on also by transplanted women, under careful criteria and monitoring. Our experience too, even if limited in number (4 patients) reported in this article confirms this conviction.

[The reliability of the grading assessment of the biopsy samples in malignant colorectal neoplasms].

The authors evaluate the results of preoperative bioptic grading compared with those obtained from postoperative specimens. Altogether, there was nonagreement in 45% of cases; therefore there is the risk of underestimating the biological aggressiveness of the disease. In fact, 68% of patients who were assessed as G1 in preoperative staging were found to have a higher degree of neoplastic dedifferentiation.
