Abstract |
Chronic kidney disease (CKD) is now an accepted long-term complication of allogeneic hematopoietic stem cell transplantation. Calcineurin inhibitors (CNI), which are used for prophylaxis and treatment of graft-versus-host disease (GVHD), have been associated with the development of nephrotoxicity. Hypertension (HTN) and thrombotic microangiopathy (TMA) are 2 comorbidities linked to CKD. T cell depletion (TCD) of stem cell grafts can obviate the need for the use of CNI. We conducted a retrospective analysis of 100 patients who underwent TCD transplantation: 30 in group A were conditioned without total-body radiation (TBI) and 70 in group B received a TBI containing regimen. None of the patients received CNI. The median age was 55.5 and 45 years for groups A and B, respectively. Eleven patients developed TMA, all in group B. The 2-year cumulative incidence of sustained CKD was 29.2% and 48.8% in group A and group B, respectively, with a mean follow-up of at least 21 months. CKD free survival was better in the non-TBI group (P = .046). Multivariable survival analysis revealed that exposure to TBI, older age, and TMA were risk factors for CKD. The incidence of new onset or worsening HTN was 6.7% and 25.7% (P = .03) in group A and B, respectively. The use of TBI (P = .0182) and diagnosis of TMA (P = .0006) predisposed patients to the development of HTN using univariable logistic regression models. Thus, despite the absence of CNI, a proportion of these older patients in both groups developed CKD and HTN.
