SummaryThe incidence of hypertension (mean diastolic pressure above 90 mm Hg) was evaluated in 85 patients with renal transplants whose follow-up ranged from 3 to 84 months.Bilateral nephrectomy had been performed in 80 recipients. The proportion of hypertensive subjects rose during the first three months, subsequently stabilised around 50-60% for up to five years, and then decreased slightly during the next two years. Over the years hypertension fluctuated so that one-third of the initially hypertensive patients became normotensive, and over one-third of the initially normotensive patients became hypertensive.The main single aetiological factor was renal failure.A significant relation between steroid dosage and blood pressure was found in only a quarter of the hypertensive patients, and in another quarter no cause could be found.

Cannabis use is associated with a lower IR risk in HIV-HCV-coinfected patients. The benefits of cannabis-based pharmacotherapies for patients concerned with increased risk of IR and diabetes need to be evaluated in clinical research and practice.

Since 1966, we have performed 41 renal transplants from unrelated living donors (ULD), 39 of which were "emotionally related". All donor-recipient pairs included in the present series were AB0-compatible. Recipients included 37 with primary and 4 with secondary transplants; 2 of the latter were diabetics. We compared these results to those of 41 recipients of cadaver donor kidneys matched for age, sex, immunosuppressive regimen, rank, and year of transplant, focusing our attention on the subgroups of patients under cyclosporin A (CyA) therapy (n = 24). We found that ULD transplantation was as successful as cadaver transplantation with good HLA matching: at 3 years, graft survival rates were 81% in ULD versus 86% in the control group under CyA. Moreover, grafts from ULD functioned more rapidly (no post-transplant dialysis and 70% of the patients with serum creatinine below 2 mg/dl within 3 days post-transplant). Graft tolerance was equivalent in both groups (50% of the patients experienced no rejection). We conclude that despite poor HLA matching, ULD transplantation with CyA as the basic immunosuppressive agent offers good results: benefiting from the quality of living donor kidney grafts, it helps to alleviate the persistent shortage of cadaver donors.
