neutropenia/hypoxia

The fall in white blood cells (WBC) and arterial oxygen pressure that occurs during hemodialysis was investigated as a function of different dialysis membranes and different sterilization methods. 8 chronic hemodialysis patients were studied and each was dialyzed with three different membranes:

Most investigators believe that the pulmonary endothelial damage that is characteristic of the adult respiratory distress syndrome (ARDS) requires the action of neutrophils. In a retrospective review of patients with ARDS, we looked for cases that had developed in patients who already had

Activated polymorphonuclear leukocytes (PMNs) are implicated in the pathogenesis of acute lung injury (ALI) associated with sepsis. Adhesion of activated PMNs to endothelial monolayers is mediated by the CD18 adhesion-receptor complex on the PMN cell surface. Monoclonal antibody 60.3 (MoAb 60.3)

We conducted a prospective, randomized, double-blind study comparing amphotericin B colloidal dispersion (ABCD) with amphotericin B in the empirical treatment of fever and neutropenia. Patients with neutropenia and unresolved fever after > or = 3 days of empirical antibiotic therapy were stratified

Respiratory failure is a severe complication of invasive pulmonary aspergillosis (IPA). Its pathogenesis is not well understood. We herein describe three cases of subacute respiratory failure that occurred during the recovery phase of neutropenia following induction chemotherapy for acute leukaemia

Techniques for the detection of neutrophil antibodies include leukoagglutination, cytotoxic assays, antiglobulin consumption tests, immunofluorescence, quantitation of cell-bound IgG, and opsonization assays. Employment of the various methodologies have led to the identification of neutropenic

Introduction Febrile neutropenia (FN) is a dreaded complication of cancer chemotherapy and frequently associated with respiratory infections. Flexible bronchoscopy (FB) serves as a useful diagnostic tool in this regard. Objective To determine the diagnostic yield, safety and clinical implications of

We have previously shown that intravascular platelet activating factor (PAF) causes ischemic bowel necrosis in rats morphologically similar to neonatal necrotizing enterocolitis (NEC). Because endotoxin (LPS) and hypoxia are risk factors for NEC, we studied their effect on PAF metabolism and the

Dialysis-associated hypoxemia is frequently of clinically significant magnitude and is incompletely understood. In order to investigate the hypoxemia directly we labelled a patient's white blood cells with 111Indium-oxine prior to hemodialysis with acetate or bicarbonate baths. Both dialysate

Hypoxemia during hemodialysis may result from several differing processes. We initially studied patients undergoing standard acetate hemodialysis. At 15 minutes of dialysis, leukopenia (primarily neutropenia), a decline of platelet count, and hypoxemia occurred, but without a significant change in

A sheep model is described which produces acute pulmonary hypertension, leucopenia and hypoxia after blood, previously placed in contact with a Cuprophan hollow fibre artificial kidney, re-enters the circulation. Relationships between these manifestations (acute pulmonary hypertension, leucopenia

Complement activation, neutrophil stimulation, increased cellular adhesiveness, transient leukocyte margination and pulmonary leukostasis take place during hemodialysis with cellulosic dialysis membranes. Several investigators have hypothesized that complement activation is primarily responsible for

Purpose: The presence of hypoxia in the diseased bone marrow presents a new therapeutic target for multiple myeloma. Evofosfamide (formerly TH-302) is a 2-nitroimidazole prodrug of the DNA alkylator, bromo-isophosphoramide mustard, which is selectively activated under hypoxia. This trial was

We previously demonstrated vast expansion of hypoxic areas in the leukemic microenvironment and provided a rationale for using hypoxia-activated prodrugs. PR104 is a phosphate ester that is rapidly hydrolyzed in vivo to the corresponding alcohol PR-104A and further reduced to the amine and
