Improving In Vitro Detection of Sensitization to Lipid Transfer Proteins: A New Molecular Multiplex IgE Assay.

Scope: LTP-syndrome is characterized by sensitization (IgE) to multiple non-specific lipid transfer proteins (nsLTPs) with a variable clinical outcome. The treatment is primarily based on offending food avoidance. However, the determination of Pru p 3-specific IgE is currently the main diagnostic tool to assess sensitization to nsLTPs.

Standardization of a colorimetric technique for determination of enzymatic activity of diamine oxidase (DAO) and its application in patients with clinical diagnosis of histamine intolerance.

Background: Diamine Oxidase (DAO) has an essential role for degradation of exogenous histamine in the intestine; thus, histamine intolerance (HI) mainly has been correlated to a low concentration and/or activity of this enzyme. The objective of the study was to standardize a colorimetric technique to measure the enzymatic activity (function) of hDAO to then apply it to a series of 22 patients with a clinical diagnosis of HI.

Methods: For the standardization variables such as volume and type of sample, incubation time, wavelength of maximum absorption, types of substrates, and concentration of oxidized ascorbate were evaluated.

Dependent person in self-care: analysis of care needs.

Background: The aim of this study was to assess the self-care dependency levels of the dependent person at the time of home discharge and its relationship between (1) the degree of dependency of each self-care domain; (2) the previous dependency levels; and (3) the gender of the dependent person. It also aims to assess the relationship between the degree of dependency of each self-care domain, the length of admission, the length of dependency and the age of the dependent person at the time of discharge.

Methods: A cross-sectional study was conducted.

Cost-effectiveness of primary antifungal prophylaxis with posaconazole versus itraconazole in allogeneic hematopoietic stem cell transplantation.

Purpose: To evaluate the cost-effectiveness of posaconazole vs itraconazole in the prevention of invasive fungal infections (IFIs) in recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Methods: Total hospital-based costs from initial admission for allo-HSCT until day 100 after transplantation were evaluated for 49 patients in whom the clinical efficacy of antifungal prophylaxis with posaconazole vs itraconazole had been previously analyzed and reported. Clinical and economic data were used to determine the incremental costs per IFI avoided and per life-year gained for posaconazole compared with itraconazole.

Dasatinib as salvage therapy for steroid refractory and imatinib resistant or intolerant sclerotic chronic graft-versus-host disease.

Sclerotic chronic graft-versus-host disease (scGVHD) is a severe form of this disease that resembles systemic sclerosis and has limited and disappointing treatment options. Tyrosine kinase inhibitors (TKI) targeting up-regulated profibrotic pathways, such as imatinib mesylate, have been proposed as a potential therapeutic approach for patients with scGVHD. Dasatinib, a second-generation TKI with a well-established safety and efficacy profile in chronic myeloid leukemia patients, who are refractory or intolerant to imatinib, has also shown potent antifibrotic effects.
