Reconstitution of the lymphocyte population after recovery from alemtuzumab-induced depletion may on one hand have profound effects on the risk of graft rejection, or on the other hand may give rise to more tolerogenic lymphocyte subsets. One recent retrospective study of consecutive non-sensitized kidney transplant patients treated with rapid steroid taper reported that as well as higher rates of acute rejection, three-year graft survival was lower under alemtuzumab induction versus rATG.
HR, hazard ratio; CI, confidence interval. Comparative studies between induction agents within steroid-free regimens Two registry analyses have specifically assessed outcomes according to type of induction in kidney transplant patients discharged on a steroid-free regimen.Uso de Tablas termodinámicas: Interpolación lineal e interpolación doble
Data on rejection were not reported, so it is unclear whether differences in graft failure were related to a lower propensity to rejection under rATG or other causes of graft loss.
The one-year risk of graft failure was higher with alemtuzumab versus IL-2R antagonist induction odds ratio 1. Results of the ongoing SAILOR study, comparing rATG with steroid avoidance versus IL-2R antagonist induction with standard oral steroids in patients receiving low-dose tacrolimus and concentration-controlled MMF, 50 will help to clarify the relative effectiveness of each class of agent in preventing rejection in the absence of steroids.
In a large trial of kidney transplant patients stratified as either high or low immunological risk, Hanaway et al. All patients were given oral steroids to day 7, with maintenance therapy comprising tacrolimus and MPA. One notable point was a high rate of BPAR Three randomized trials of alemtuzumab with steroid avoidance have used an IL-2R antagonist in the control arm, as discussed above, but since the maintenance regimen differed between groups the effect of the induction regimen cannot be assessed.
Typically, studies of steroid withdrawal either before or after the first year post-transplant have not included induction therapy.
Although only a subanalysis, these data suggest an advantage for lymphocyte depleting induction when undertaking steroid withdrawal after kidney transplantation. Steroid withdrawal around month 6 thus appears feasible under rATG induction with or without CNI therapy, when high-risk patients are excluded. High-immunological risk patients Steroid-free immunosuppression is less frequently attempted in high-risk patients, and data are limited Table 3.
Two retrospective single-center studies in African-American populations have assessed outcomes following rATG induction with i. In this small series, the rate of BPAR at a median of Body mass index was similar in both groups. Body mass index remained stable. Steroid minimization and risk of recurrence of glomerular diseases The advantages of steroid avoidance also have to be balanced against the risk of recurrence of certain glomerulopathies. In particular, several retrospective studies have shown that recurrence of IgA nephropathy is reduced in the presence of long-term steroid therapy.
Among them, Clayton et al. After adjustment for various confounding variables, steroid use was strongly associated with a reduced risk of IgA nephropathy recurrence HR 0. Although the mechanisms involved have not been elucidated, steroid avoidance would not appear advisable in kidney transplant patients in whom kidney failure was caused by IgA nephropathy.
In other types of glomerular diseases with risk of recurrence, such as focal segmental glomerulosclerosis, membranoproliferative glomerulonephritis or lupus nephritis, for which steroids are used as part of the treatment strategy in native kidneys, some centers tend to maintain steroids in the immunosuppressive protocol after transplantation even in the absence of relevant studies.
Steroid minimization in pediatric patients Steroid-sparing strategies are of particular interest in children. Randomized trials of steroid avoidance in pediatric populations under lymphocyte-depleting induction have not, however, been carried out to date.
In a single-center prospective study, Chavers et al. Lastly, a retrospective single-center study by Wittenhagen et al. Steroid- and CNI-avoidance regimens A small number of trials have investigated novel immunosuppressive regimens that avoid both steroids and CNI therapy.
So while promising, a CNI-free strategy may not be optimal for achieving steroid-free immunosuppression even with lymphocyte-depleting induction. Other small trials have also pointed to low or acceptable rates of BPAR when alemtuzumab induction is used to support CNI-free and steroid-free therapy, 6163 one of which achieved highly minimized immunosuppression by giving bone marrow infusions, 63 but such regimens are not currently used in routine practice.
Discussion The literature contains few direct comparisons of steroid minimization regimens versus conventional steroid treatment in kidney transplant patients receiving lymphocyte-depleting induction. Studies are typically relatively small, with limited follow-up periods, and to date, the occurrence of de novo antibodies and antibody-mediated rejection is undocumented. Nevertheless, the available data show that the risk of acute rejection is low when rATG induction is given to support steroid-free regimens after kidney transplantation, at least for the first one to two years post-transplant.
In the US, it is common practice to use rATG and stop steroids by day 7, and this appears to be a reasonable approach that does not increase the risk of rejection.
In contrast, rejection may be more likely under IL-2R antagonist induction using a steroid-avoidance regimen. Induction with alemtuzumab appears effective in supporting steroid-free immunosuppression, although it is not licensed for use in solid organ transplant recipients.
For patients at high immunological risk, the limited data available suggest that steroid minimization may not be advisable even with depleting induction therapy. The availability of single-antigen bead technology, permitting more precise measurement of anti-HLA antibodies, may enable more accurate identification of high-risk individuals and feasibly, expand the pool of patients considered candidates for steroid minimization.
In children, non-randomized studies indicate that depleting induction with standard maintenance therapy effectively prevents acute rejection with steroid avoidance, an encouraging finding given the growth inhibition associated with chronic steroid administration. More ambitious regimens have been attempted which include both steroid avoidance and CNI avoidance, of which depleting induction with maintenance therapy comprising belatacept and sirolimus appears the most promising, but currently can be regarded as an experimental approach.
There is some suggestion that steroid-associated side effects such as dyslipidemia and weight gain are lower with steroid-free immunosuppression, but this has not been shown to translate to an improvement in hard clinical endpoints.
Given the lack of strong evidence in this field, no strong conclusions can be made. Early steroid therapy with subsequent withdrawal i. Where late steroid withdrawal is attempted months 3 to 6 post-transplantit seems preferable to employ tacrolimus-based immunosuppression over CsA. Overall, the effectiveness of steroid avoidance regimens in this setting is better documented than subsequent withdrawal strategies.
In summary, there is a suggestion that steroid avoidance is beneficial for patients after renal transplantation, with the potential to avoid or reduce steroid-related comorbidities.
Whilst the limited literature seems to indicate that depleting induction therapy could be the treatment of choice for steroid minimization and avoidance in kidney transplantation, the results of prospective randomized, controlled studies are eagerly awaited.

The site is a good example of past societies adaptation to hyper-arid environments, and provides new insights into the early human occupations of South America. The well-preserved stratigraphic record, together with 13 radiocarbon dates, show that the site was occupied around 11, cal BP. One can highlight the presence of flakes of allochthonous raw-materials, imported from other areas, which have been flaked at Chipana-1 in order to produce bifacial tools.
Chipana-1 was an important location for Late Pleistocene hunter-gatherer groups, poorly known until now, for the gathering of raw-materials and lithic production in the Atacama Desert.

Even before this date, the arrival of Phoenicians on the continent and their subsequent spread throughout the north of it, initiated a rich process of contacts, interchanges and relations with the Libyan-Berber populations that inhabited the zone from time immemorial. All these subjects are treated in the present book through some specific scientific contributions whose geopolitical frame is the whole Proconsular Africa.
Most of the articles in this volume are dedicated to the world of images, but others also treat many other issues as Historiography, Archaeology of Architecture, Libyan-Berber ethnicities and even cultural parallels between North Africa and the Iberian Peninsula.
The result of that research was the book Africa. In this case, she was specifically devoted to the study of the collection of sculptural materials belonging to the city and to the villas of the Tusculan surroundings. Due to this research she published the volume Tusculana Marmora. She is specialist in the Libyan-Berber world, subject to which she dedicates her current doctoral thesis. His investigations are focused on Landscape Archaeology in the Baetica, Africa and Italy, besides his participation in research projects on domestic spaces in Pompeii and the Roman sculpture of Carthage.
The History of archaeological research has only recently become a research topic of interest within Spain. Eleven papers are presented in this proceedings volume. They address several aspects from different perspectives that collectively enrich the historiography of Spanish archaeological research. EL caso de Andalucia. Desiderio Vaquerizo Gil, Catedra? El tema, extenso y complejo, abarca muchos a? En el panorama de la arqueologi? In recent years, archeology has been reflecting more and more on how we can use the senses to generate "non-Cartesian" models and, therefore, alternatives to those that dominated the discipline from its origins.
The book starts from the premise that sensoriality can not be separated from affections, emotions or memories. Taking into account this idea, various South American archaeologists seek to "indiscipline the senses", exploring the potential that these new approaches offer to explore the material world.
El libro parte de la premisa que la sensorialidad no puede ser separada de los afectos, de las emociones o de las memorias.
The aim of this work is to analyze Late Prehistoric graphical markers, comprising paintings, engravings, Megalithic elements, and other portable objects. All of them can be described as post-paleolithic or Schematic Art over various surfaces.

The methodology is based on systematic registration of all archaeological sites. It tests geographical markers according to their strategic location pre-eminence and visibility and their relationship with other funerary, habitable and resources sites.
This has allowed parietal surfaces megaliths, caves, shelters and mobile pieces to be given coordinate position for the first time in the region, which has demonstrated abundant and complex prehistoric graphical markers.
The results achieved allow the extrapolation of settlement models, explained in chapter VI. Generally, shelters divide the territory by geographical units where the settlers have access to a variety of economic resources and transit networks. About the Author Dr. Her research interests include landscape archaeology, megalithic territories and their symbolism, Prehistoric Rock Art in the Iberian Peninsula and Late Prehistory in the inner basin of the Tajo river.
