Clinical studies focused on disease-specific outcomes of cord blood transplant (CBT) from unrelated donors are limited. We analyzed the outcome and prognostic factors of 49 adults with high-risk acute myelogenous leukemia (AML) receiving single-unit CBT from unrelated donors after myeloablative (MA) conditioning at a single institution. Conditioning regimens were based on the combination of thiotepa, busulfan (Bu), cyclophospamide (Cy), or fludarabine (Flu), and antithymocyte globulin (ATG). Cumulative incidence of myeloid and platelet engraftment was 96% and 73% at a median time of 20 and 62 days, respectively. Engraftment was significantly faster for patients receiving higher doses of CD34(+) cells. Confidence Interval of graft-versus-host disease (GVHD), acute GVHD (aGVHD) grade II-IV, III-IV, and extensive chronic GVHD (cGVHD) were 26%, 15%, and 30%, respectively. Leukemia-free survival (LFS), nonrelapse mortality (NRM), and relapse at 2 years were 42%, 39%, and 19%, respectively. Low number of total nucleated cells (TNC) had a negative impact on NRM and LFS. Patients transplanted in first complete remission (CR1) receiving TNC above 2 x 10(7)/kg had a 4-year LFS of 75%. These results show that CBT from unrelated donors is a curative treatment for a substantial number of patients with high-risk AML, particularly if transplant is performed with highly cellular units in patients in first CR.
PNH is a heterogeneous disorder involving the peripheral nerves in patients with a high propensity for developing autoimmunity. Associated muscle diseases are frequent in the form of myositis, myasthenia gravis, or nonspecific myopathic pathologic findings. VGKC-Abs were uncommon in this series.
There is no information on the efficacy and safety of anticytomegalovirus (CMV) prophylaxis with intravenous ganciclovir or oral valganciclovir after unrelated cord-blood transplantation (UCBT). This issue was addressed in 151 adults (117 CMV-seropositive) undergoing UCBT at a single institution. The first 38 CMV-seropositive recipients were assigned to receive prophylactic ganciclovir, and the next 79 were given valganciclovir after engraftment. The cumulative incidence (CI) of CMV infection and disease was similar in patients receiving valganciclovir or ganciclovir (59% versus 55%, P = .59; and 9% versus 18%, P = .33, respectively). The toxicity profile and CI of nonrelapse mortality (CMV) and infection-related mortality did not differ between drugs. Patients receiving valganciclovir required fewer visits to the day hospital (P = .04). The CI of CMV infection and disease in 34 CMV-seronegative recipients was 12% and 6%, indicating that tight CMV monitoring is mandatory in this subset. The recipient's CMV serostatus, acute and extensive chronic graft-versus-host disease (aGVHD, cGVHD) were the main risk factors for CMV infection, and aGVHD for CMV disease. This study suggests that prophylaxis with oral valganciclovir is as safe and effective as intravenous ganciclovir for preventing CMV infection and disease after UCBT, but valganciclovir reduces the use of hospital resources.
A substantial proportion of mildly hypertensive patients presenting in primary care have LVH determined by ECHO. Our results suggest that this procedure could significantly improve cardiovascular risk stratification in those patients with multiple risk factors, but no evidence of target organ damage by routine investigations.
Characteristics of Spanish ITP patients are comparable to those from other countries. Although a high response rate to first-line treatments is observed, at 1 year, the disease persists in around one quarter of patients. Overall therapeutic management in Spain conforms to current recommendations, except for an excessive duration of corticosteroids therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
