Kidney transplantation in a patient with preformed and exclusively anti-HLA-Cw ...
Santos, S.; Castro, A.; Campos, A.; Pedroso, S.; Dias, L.; Castro-Henriques, A.We report a patient who had received a first kidney transplant and had preformed DSA anti-HLA-Cw, developing AMR C4d+ soon after transplant. Classically anti-HLA-Cw are considered less immunogenic and are not considered in many organ allocation systems or immunologic risk stratification algorithms, including in Portugal. However, data from literature confirms that their presence is as deleterious as DSA anti-HL...
BK virus nephropathy in kidney transplantation - A literature review following ...
Barreto, P.; Almeida, M.; Dias, L.; Vieira, P.; Pedroso, S.; Martins, L.; Castro-Henriques, A.; Cabrita, A.Over the last 15 years, better immunosuppressive drugs have decreased acute rejection rates in kidney transplantation but have also led to an increase in the incidence and impact of BK virus nephropathy. The authors report the case of a 62 -year -old man submitted to a renal transplant of a deceased donor with an immunosuppression regimen free of rabbit anti -thymocyte globulin and tacrolimus, in whom BK nephro...
Implications for patients waiting for a kidney transplant of using the calculat...
Magriço, R.; Malheiro, J.; Tafulo, S.; Pedroso, S.; Almeida, M.; Martins, L.; Dias, L.; Castro-Henriques, A.; Cabrita, A.Introduction: Kidney transplant improves survival even in highly‑sensitized (HS) patients. To overcome their disadvantage in accessing transplantation, those with high Complement Dependent Cytotoxic PRA (CDC‑PRA) receive additional points during allocation. Whether this strategy reaches all HS patients and how long they wait for a transplant is largely undetermined. Methods: Patients on our unit’s active wait‑l...
Malignancy after renal transplantation: a single-centre experience
Vieira, P.; Bareto, P.; Pedroso, S.; Almeida, M.; Martins, L.; Dias, L.; Castro-Henriques, A.; Cabrita, A.Introduction: Malignancy management in renal transplant recipients is becoming a major factor affecting long‑term patient survival. Thus, we intended to evaluate both incidence and prognosis of malignant diseases following renal transplantation at a single centre in Portugal. Methods: We studied retrospectively the 2,358 patients who underwent kidney transplantation (KT) between 1983 and 2014. Apart from descri...
Impact of preformed donor-specific antibodies against HLA class I on kidney gra...
Santos, S.; Malheiro, J.; Tafulo, S.; Dias, L.; Carmo, R.; Sampaio, S.; Costa, M.; Campos, A.; Pedroso, S.; Almeida, M.; Martins, L.; Henriques, C.AIM: To analyze the clinical impact of preformed antiHLA-Cw vs antiHLA-A and/or -B donor-specific antibodies (DSA) in kidney transplantation. METHODS: Retrospective study, comparing 12 patients transplanted with DSA exclusively antiHLA-Cw with 23 patients with preformed DSA antiHLA-A and/or B. RESULTS: One year after transplantation there were no differences in terms of acute rejection between the two groups (3...
The first ABO-incompatible kidney transplantation performed in Portugal
Barreto, P.; Vieira, P.; Dias, L.; Almeida, M.; Pedroso, S.; Martins, L.; Castro-Henriques, A.; Bini, M.; Cabrita, A.Kidney transplantation is the optimal treatment of end-stage renal disease (ESRD) improving survival and quality of life for most recipients. In our country, potential living donors have been refused due to the ABO incompatibility barrier. However, ABO -incompatible living donor kidney transplant is presently common practice in several countries with good outcomes. The authors describe a case of a 49-year-old f...
Impact of pre-transplant anti-MICA sensitization in graft rejection and survival
Costa, R.; Malheiro, J.; Tafulo, S.; Santos, C.; Almeida, M.; Pedroso, S.; Martins, L.; Dias, L.; Castro-Henriques, A.Background: Evidence supporting deleterious effect of preformed major histocompatibility class I chain-related A (MICA) antibodies in rejection incidence and graft survival is still unclear. Methods: Retrospective analysis of 554 kidney transplanted patients. Comparison between positive or negative for MICA antibodies patients was performed to characterize sensitizing triggers. Further classification according ...
Histiocytic sarcoma; case report of a rare disease in a kidney transplant recip...
Ventura Aguiar, P.; Dias, C.; Azevedo, P.; Silva, H.; Almeida, M.; Pedroso, S.; Martins, L.; Dias, L.; Rodrigues, A.; Viscaíño, R.; Cabrita, A.BACKGROUND: Histiocytic sarcoma (HS) is a rare hematologic neoplasm with a few hundred cases having been described to date.
Posttransplant allosensitization in low immunological risk kidney and kidney-pa...
Malheiro, J.; Tafulo, S.; Dias, L.; Martins, La Salete; Fonseca, Isabel; Almeida, M.; Pedroso, S.; Freitas, F.; Beirão, I.; Castro-Henriques, A.INTRODUCTION: Posttransplantation allosensitization prevalence and effect on kidney grafts outcomes remain unsettled. METHODS: Between 2007 and 2012, 408 patients received a primary kidney graft (with 68 patients also receiving a pancreas graft) after a negative cytotoxic crossmatch. All patients had a pretransplant negative anti-HLA screening and 0% panel reactive antibodies. We analyzed retrospectively the re...
Predictive value of bioelectrical impedance analysis parameters in the mortalit...
Rodrigues, R.; Oliveira, B.M.P.M.; Pedroso, S.; Azevedo, J.N.; Azevedo, P.; Oliveira, J.P.; Silva, F.; Travassos, F.; Rodrigues, T.; Pereira, O.Background: Protein-energy wasting is a very common complication in hemodialysis patients and influences their survival. All hemodialysis patients should have their nutritional status evaluated regularly using multiple methods. The bioelectrical impedance analysis has been widely used in the nutritional assessment. The objective of this study was to evaluate, for a period of 7 years, to the prognostic value of ...
