IMPORTANCE Noninvasive ventilation has been recommended to decrease mortality among immunocompromised patients with hypoxemic acute respiratory failure. However, its effectiveness for this indication remains unclear. OBJECTIVE To determine whether early noninvasive ventilation improved survival in immunocompromised patients with nonhypercapnic acute(More)
Invasive pulmonary aspergillosis (IPA) is a life-threatening infection documented in up to 15% of hematology patients who require intensive care for acute respiratory failure. We report outcomes in hematology patients given mechanical ventilation (MV) with IPA. Retrospective study of all hematology patients given MV with IPA between January 1998 and March(More)
Waldenstrom macroglobulinemia (WM) is characterized by widespread involvement of the bone marrow at the time of diagnosis, implying continuous homing of WM cells into the marrow. The mechanisms by which trafficking of the malignant cells into the bone marrow has not been previously elucidated. In this study, we show that WM cells express high levels of(More)
PURPOSE We hypothesized that targeting both Akt and heat shock protein (HSP) 90 would induce cytotoxic activity against multiple myeloma (MM) cells and target the bone marrow (BM) microenvironment to inhibit angiogenesis, osteoclast formation, as well as migration and adhesion of MM cells. EXPERIMENTAL DESIGN MM cell lines were incubated with perifosine(More)
The current most powerful prognostic model in Multiple Myeloma (MM) combines beta-2 microglobulin (b2m) with albumin, corresponding to the International Staging System (ISS). However, the prognosis of patients within the ISS stage I (high albumin and low b2m) may vary. Ki-67 is a nuclear protein associated with cell proliferation. We retrospectively(More)
PURPOSE Nucleoside analogs (NAs) are considered as appropriate agents in the treatment of Waldenström macroglobulinemia (WM), a lymphoplasmacytic lymphoma. Sporadic reports on increased incidence of transformation to high-grade non-Hodgkin's lymphoma and development of therapy-related myelodysplasia/acute leukemia (t-MDS/AML) among patients with WM treated(More)
Waldenstrom macroglobulinemia (WM) is an incurable low-grade lymphoplasmacytic lymphoma. We demonstrate up-regulated Akt activity in WM, and that Akt down-regulation by Akt knockdown and the inhibitor perifosine leads to significant inhibition of proliferation and induction of apoptosis in WM cells in vitro, but not in normal donor peripheral blood and(More)
Waldenstrom macroglobulinemia (WM) is an incurable low-grade lymphoma characterized by bone marrow (BM) involvement of IgM secreting lymphoplasmacytic cells. The induction of unfolded protein response (UPR) genes ("physiologic" UPR) enables cells to differentiate into professional secretory cells capable of production of high amounts of endoplasmic(More)

Anti-factor VIII antibodies represent a unique model to study the relationship between natural autoreactivity (natural antibodies to factor VIII of healthy individuals), disease-associated autoimmunity ("spontaneous" factor VIII inhibitors of patients with anti-factor VIII autoimmune disease) and antigen-driven immune responses (immune inhibitors in(More)
