Unfortunately, corticosteroids (as the basis for post-transplant immunosuppression) have been directly associated as one of the major cardiovascular risk factors.<span class="elsevierStyleSup">6,7</span></p><p class="elsevierStylePara">The prevalence of diabetes mellitus, obesity and metabolic syndrome in the general population is increasing,<span class="elsevierStyleSup">8,9 </span>and the risk of developing them after transplantation with the use of corticosteroids could be higher, thus leading to an increase in morbidity and mortality. In fact, the use of these drugs is associated with <span class="elsevierStyleItalic">de novo</span> diabetes after renal transplantation.<span class="elsevierStyleSup">10 </span>A strategy aimed at reducing these comorbidities is avoiding the use of, or the withdrawal of corticosteroids (whether it be late or early), after transplantation, whenever the risk of AR and graft survival are not compromised; however, the results in this regard have been controversial.<span class="elsevierStyleSup">11-13</span></p><p class="elsevierStylePara">Our population and probably some others are at greater risk of developing diabetes mellitus and other complications after renal transplantation, and as such, strategies for avoiding or reducing risk factors in this type of patient are necessary. Therefore, the objective of this study was to compare the effect of early steroid withdrawal (ESW) on the estimated glomerular filtration rate (eGFR), graft survival, frequency of AR and the metabolic profile in a renal transplantation cohort (ESW-C) treated with tacrolimus (TAC) and mycophenolate mofetil (MMF), in comparison with a control group (C-C) treated with the internationally recommended triple immunosuppression regimen (TAC, MMF and PDN).</p><p class="elsevierStylePara"> </p><p class="elsevierStylePara"><span class="elsevierStyleBold">MATERIAL AND METHOD</span></p><p class="elsevierStylePara"> </p><p class="elsevierStylePara">A retrospective cohort study was carried out on 32 renal graft recipients at the CMNO, IMSS Specialist Hospital in whom corticosteroid treatment was withdrawn. These patients received transplantations between December 2005 and July 2009, and were followed up until July 2010. During the study period, a total of 989 renal transplantations were performed (48 deceased donor), mostly from related living donors. Most patients selected received transplants from living donors (58/60) and all had a low immunological risk (panel reactive antibody against HLA classes I and II <30%). The ESW is an intervention that is very infrequently performed in our hospital and the decision to withdraw corticosteroids was taken by the nephrologist in accordance with the patient’s characteristics and their experience. We included all of the patients for whom corticosteroids were withdrawn during this period (ESW-C); the C-C consisted of recipients who had the same transplantation time, immunosuppression regime and immunological risk. Patients with a history of using corticosteroids before transplantation, diabetes mellitus, delayed renal graft function (those requiring renal replacement therapy immediately after transplantation) and multiple organ transplantation were excluded.</p><p class="elsevierStylePara">All patients received our hospital’s standard induction immunosuppression regimen based on: 0.18mg/kg/day TAC (divided into two doses), 2g/day MMF (divided into two doses), 500mg intravenous methylprednisolone (MPD) (peri-operatively) and 20mg of basiliximab peri-operatively and four days after transplantation.

However, there is a growing tendency to avoid their use due to their side effects and the negative impact on graft and patient survival, even at low doses.<span class="elsevierStyleSup">18-20 </span>Results of various studies in which steroids have been withdrawn have been controversial, probably due to the heterogeneity of the different immunosuppression protocol used, based on cyclosporine, TAC, azathioprine, MMF, rapamycin or everolimus,<span class="elsevierStyleSup">12,21 </span>with or without antibodies (monoclonal or polyclonal).<span class="elsevierStyleSup">13,22-24 </span>In the Latin American population, there are no data available for this intervention, especially with homogeneous immunosuppression regimens based on TAC and MMF. Nowadays, there is a documented higher risk in the development of obesity and diabetes in various populations,<span class="elsevierStyleSup">8,9 </span>which could be exacerbated after renal transplantation (and corticosteroids could be a major risk factor). In our setting, a higher risk of <span class="elsevierStyleItalic">de novo</span> diabetes after transplantation was associated with corticosteroid use;<span class="elsevierStyleSup">10 </span>medical interventions such as ESW may be beneficial in transplant recipients. Obviously, this intervention must not increase the risk of AR or decrease renal function. Initially, only patients with a low immunological risk and who ideally use potent immunosuppressive drugs would be candidates for steroid withdrawal.</p><p class="elsevierStylePara">We included patients who met these requirements and our results were similar to those of other studies carried out in similar conditions.<span class="elsevierStyleSup">25 </span>One of the main concerns with the withdrawal of corticosteroids was the greater risk of AR. The results of some studies that have reported a high rate<span class="elsevierStyleSup">13 </span>of AR are questionable, since a significant number of them did not perform renal biopsies (gold standard) or even reported the methodology for diagnosing AR, which could explain the results of a higher AR rate. In this study, AR was documented with protocol or indicated biopsies, and as such, both subclinical and clinical rejections were identified. Our results with ESW did not predict the development of AR or the incidence of AR during the first year and this was consistent with that reported by other hospitals.<span class="elsevierStyleSup">26 </span>Most late episodes of AR were documented in biopsies carried out due to an increase in serum creatinine and were more common in C-C (29%) than in ESW-C (3%). A possible explanation for this result is that the ESW-C had higher toxicity due to TAC documented histopathologically than the C-C, in spite of patients in the ESW-C receiving lower doses of TAC (data not displayed). From a pharmacological point of view, corticosteroids are cytochrome P450 inducer stimulants (isoenzyme CYA4) responsible for the biotransformation of TAC, and in ESW, this favours greater bioavailability of TAC, which may explain why patients with ESW had greater toxicity due to TAC and a lower rate of AR.<span class="elsevierStyleSup">27,28 </span>In the C-C, the eGFR was lower in comparison with that of the ESW-C, which could be explained by the higher rate of AR observed in this group during follow-up. The withdrawal of steroids could potentially improve the haemodynamic and metabolic profile. González-Molina et al.<span class="elsevierStyleSup">29</span> retrospectively assessed 923 kidney recipients (deceased donor) with steroid withdrawal and found lower blood pressure, total cholesterol and triglycerides. In this study, both groups had an appropriate control of blood pressure and serum lipids; however, ESW-C achieved this control with the use of a lower dose and frequency of drugs and these results were consistent with other studies.<span class="elsevierStyleSup">13 </span>These results have encouraged us to continue this intervention in our population through clinical trials to test these findings.</p><p class="elsevierStylePara"><span class="elsevierStyleBold"> </span></p><p class="elsevierStylePara"><span class="elsevierStyleBold">CONCLUSION</span></p><p class="elsevierStylePara"> </p><p class="elsevierStylePara">In patients with a low immunological risk, with an immunosuppression regimen based on TAC and MMF, ESW does not change graft survival, renal function or the rate of AR in this cohort. Toxicity due to TAC (confirmed by biopsy) tends to be more common in ESW-C than in the controls and the reason for this merits further research. ESW-C patients had a lower requirement for antihypertensive drugs and hypolipidaemic agents in comparison with the C-C, which suggests a better metabolic profile. Our findings require further clinical trials in homogenous populations in order to avoid controversy with this type of intervention.</p><p class="elsevierStylePara"> </p><p class="elsevierStylePara"><span class="elsevierStyleBold">Conflicts of interest</span></p><p class="elsevierStylePara"> </p><p class="elsevierStylePara">The authors declare that they have no conflicts of interest related to the contents of this article.</p><p class="elsevierStylePara"><a href="grande/12028_16025_56435_en_t110.12028_i.jpg" class="elsevierStyleCrossRefs"><img src="12028_16025_56435_en_t110.12028_i.jpg" alt="Demographic and transplantation characteristics."></img></a></p><p class="elsevierStylePara">Table 1.
