چکیده

Method A total of 16 patients with clinically well-established maculopapular exanthema due to antiepileptic drugs hypersensitivity in remission state and 15 drug-exposed control donors without DHR were included to the study. Peripheral blood mononuclear cells of investigated individuals were isolated and cultured under defined conditions with drugs. IFN-gamma production was measured with electrochemiluminescence array assay and ELISA (cytokine level in cell culture supernatant), ELISpot (cytokine secreting cells), flow cytometry (intracellular staining in CD3+ CD4+ cells).

  Background: Administration of phenytoin can been associated with severe adverse reactions such as hypersensitivity reactions. Lymphocyte transformation test (LTT) can be a useful method for determination of the drug, which has caused hypersensitivity reaction. This study was done to evaluate the results of lymphocyte transformation test in patients with delayed hypersensitivity reactions foll...

Preliminary evaluation of whole-blood gamma interferon release for clinical assessment of cellular immunity in patients with active coccidioidomycosis.

Assessment of the cellular immune response in coccidioidomycosis has epidemiologic and prognostic importance. Measurement of delayed-type hypersensitivity to skin testing has been used in the past to determine cellular immunity in coccidioidomycosis. However, no skin tests are currently available in the United States. Assay of gamma interferon (IFN-gamma) release in whole blood in response to i...

Predominance of IL-5-secreting drug-specific T cells in subgroups of patients with drug-induced delayed-type hypersensitivity reaction

Background Drug hypersensitivity reactions (DHRs) can be classified into IgE-induced, immediate type and T-cell mediated, delayed-type reactions. While the former are considered as Th2-driven immune responses characterized by IL-5secretion, the later are regarded as mainly provoked by IFN-gamma-producing Th1 cells. However, it has been suggested that delayed-type DHRs could also be elicited by ...

Design and Comparative Evaluation of In-vitro Drug Release, Pharmacokinetics and Gamma Scintigraphic Analysis of Controlled Release Tablets Using Novel pH Sensitive Starch and Modified Starchacrylate Graft Copolymer Matrices

The present investigation deals with the development of controlled release tablets of salbutamol sulphate using graft copolymers (St-g-PMMA and Ast-g-PMMA) of starch and acetylated starch. Drug excipient compatibility was spectroscopically analyzed via FT-IR, which confirmed no interaction between drug and other excipients. Formulations were evaluated for physical characteristics like hardness,...
