Kidney transplantation in HIV-positive patients: a report of 14 cases

The HAART reduces the risk of HIV-related renal disease but the incidence of end-stage renal disease (ESRD). Therefore, efficacy and safety of renal transplantation (Tx) is an important resource in the HIV-infected population. We reported the results of kidney Tx in HIV+patients from deceased donors from June 2007 to March 2012 at our institution. The patients had to have CD4+T-cell counts ≥200/mm 3 and undetectable plasma HIV-RNA if on HAART. The induction immunosuppressive therapy consisted of metilprednisolone and basilixmab; tacrolimus and/or mycofenolic acid were used for maintenance therapy. The therapeutic drug monitoring (TDM) has been performed for the adjusting of both their doses [1]. A total of 14 patients underwent kidney Tx. They were on dialysis (haemodialysis =13, 92.9%; peritoneal =1, 7.1%) for 5±3.1 years and they were included on the Tx waiting list for 10±8 months. The baseline characteristics are showed in Table 1. At the last available point of follow-up (median =42.8 months, IQR =8.5-55.2), 8 out of the 13 patients (61.6%) without steroid had at least one acute rejection episode, but only 1 patient lost the graft, after 43 months (7.1%) due to chronic rejection associated with infectious and vascular complications. After Tx the median CD4T-cell count increased from 382.5 (IQR range =233-415) to 434 (IQR range =282-605) cells/mm 3 (p =0.055). In Figure 1 are reported the CD4+trends of 9 patients with a follow-up of at least 6 months. HIV infection was well controlled, with only 2 (14.3%) cases of virological failure which were promptly resolved after HAART regimen modification. Table 1 shows the observed infectious complications. The skin Kaposi sarcoma has been resolved by switching to immunosuppressive therapy with sirolimus [2]. Kidney Tx appears to be safe in HIV-positive patients undergoing HAART. The viro-immunological parameters remained well controlled with no increases in infectious complications or neoplasm and a satisfactory control of HIV infection. However, the high rejection rate is a serious concern and suggests to consider a steroid-containing immunosuppressive regimen also in these patients.
