    Long-term survival and late deaths after hematopoietic cell transplantation for primary immunodeficiency diseases and inborn errors of metabolism.
    (Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2012-09) Eapen, Mary; Ahn, Kwang Woo; Orchard, Paul J; Cowan, Morton J; Davies, Stella M; Fasth, Anders; Hassebroek, Anna; Ayas, Mouhab; Bonfim, Carmem; O'Brien, Tracey A; Gross, Thomas G; Horwitz, Mitchell; Horwitz, Edwin; Kapoor, Neena; Kurtzberg, Joanne; Majhail, Navneet; Ringden, Olle; Szabolcs, Paul; Veys, Paul; Baker, K Scott
    It is uncertain whether late mortality rates after hematopoietic cell transplantation for severe combined immunodeficiency (SCID), non-SCID primary immunodeficiency diseases (non-SCID PIDD), and inborn errors of metabolism (IEM) return to rates observed in the general population, matched for age, sex, and nationality. We studied patients with SCID (n = 201), non-SCID PIDD (n = 405), and IEM (n = 348) who survived for at least 2 years after transplantation with normal T cell function (SCID) or >95% donor chimerism (non-SCID PIDD and IEM). Importantly, mortality rate was significantly higher in these patients compared with the general population for several years after transplantation. The rate decreased toward the normal rate in patients with SCID and non-SCID PIDD beyond 6 years after transplantation, but not in patients with IEM. Active chronic graft-versus-host disease at 2 years was associated with increased risk of late mortality for all diseases (hazard ratio [HR], 1.87; P = .05). In addition, late mortality was higher in patients with non-SCID PIDD who received T cell-depleted grafts (HR 4.16; P = .007) and in patients with IEM who received unrelated donor grafts (HR, 2.72; P = .03) or mismatched related donor grafts (HR, 3.76; P = .01). The finding of higher mortality rates in these long-term survivors for many years after transplantation confirms the need for long-term surveillance.

    National Cancer Institute, National Heart, Lung and Blood Institute/Pediatric Blood and Marrow Transplantation Consortium First International Consensus Conference on late effects after pediatric hematopoietic cell transplantation: the need for pediatric-specific long-term follow-up guidelines.
    (Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2012-03) Pulsipher, Michael A; Skinner, Roderick; McDonald, George B; Hingorani, Sangeeta; Armenian, Saro H; Cooke, Kenneth R; Gracia, Clarisa; Petryk, Anna; Bhatia, Smita; Bunin, Nancy; Nieder, Michael L; Dvorak, Christopher C; Sung, Lillian; Sanders, Jean E; Kurtzberg, Joanne; Baker, K Scott
    Existing standards for screening and management of late effects occurring in children who have undergone hematopoietic cell transplantation (HCT) include recommendations from pediatric cancer networks and consensus guidelines from adult-oriented transplantation societies applicable to all HCT recipients. Although these approaches have significant merit, they are not pediatric HCT-focused, and they do not address post-HCT challenges faced by children with complex nonmalignant disorders. In this article we discuss the strengths and weaknesses of current published recommendations and conclude that pediatric-specific guidelines for post-HCT screening and management would be beneficial to the long-term health of these patients and would promote late effects research in this field. Our panel of late effects experts also provides recommendations for follow-up and therapy of selected post-HCT organ and endocrine complications in pediatric patients.
