IgAN emerged as an independent predictor of worse graft outcome in the long-term. Recurrence of IgAN seems to progressively reduce in transplants performed from 1981 to 2010.

The occurrence of fatal and nonfatal cardiovascular events after successful renal transplantation not only relates to baseline cardiovascular risk factors present at transplantation, but also to immunosuppressive drugs and posttransplantation traditional and nontraditional risk factors.

The 2 year study results confirm that tacrolimus is a highly efficacious cornerstone immunosuppressant in kidney transplantation. Tacrolimus-based immunosuppression may induce long-term benefits with regard to graft function and graft survival. The overall side-effect profile is considered to be favourable.

Sixty-seven out of 100 kidney transplant recipients treated with cyclosporin and methylprednisolone were evaluated for the presence of dermatological manifestations. Only 2 patients had no dermatological lesions; 80% had iatrogenic lesions, 38% infectious, 13% miscellaneous, 3% cancerous lesions, while 28% had cutaneous manifestations related to previous uremic state. Most of the lesions concerned the pilosebaceous unit: hypertrichosis (60%), epidermal cysts (28%), pilar keratosis (21%), acne (15%), folliculitis (12%) and sebaceous hyperplasia (10%). Among infectious manifestations, viral lesions were the most frequent and were very severe in the first month after transplantation. Two patients developed a squamous-cell epithelioma and a probable cutaneous lymphoma, respectively.

The influence of three different immunosuppressive regimens with cyclosporine (CsA) on the development of osteopenia in renal transplant patients was assessed. Fifty-three adults with first kidney transplants participated in a randomized trial to analyze the efficacy of three different immunosuppressive regimens: CsA alone (group 1), CsA plus steroids (group 2), and CsA plus steroids plus azathioprine (group 3). Lumbar spine bone mineral density was assessed by dual energy x-ray absorptiometry every 6 months for 18 months. The values for trabecular mass were expressed as bone mineral density and as a fraction of the standard deviation of the mean of the normal value for patient's sex and decade of age (Z-score). Statistical analysis was performed on Z-score and "Z-score change" (value after 6 months minus the basal value at transplantation). At the 18th month, the Z-score increased significantly in treatment group 1 without steroids (P=0.006) and decreased significantly in steroid-treated groups 2 (P<0.001) and 3 (P<0.001). Comparing the two genders, Z-score decreased less in premenopausal women than in men (P=0.018). "Z-score change" did not correlate with steroid dosage, was high in patients with high basal bone mineral density, and was directly associated with the duration of dialysis (P=0.008). In conclusion, premenopausal transplant recipients showed a lower decrease of lumbar bone mineral density than men. In transplant recipients given CsA with steroids, lumbar bone mineral density decreased significantly, while it increased significantly in patients given CsA alone.

In the long term, B+ patients had a higher risk of death related to liver disease than C+ patients, and co-infection did not worsen patient survival.

These preliminary data underline the importance of long-term surveillance of transplant recipients, choice of immunosuppressive treatment, and careful donor selection.
