Delayed hypersensitivity to piperacillin

Allergy, 2002
. PIPERACILLIN (PP) is a wide-spectrum bactericidal ureidopenicillin. There have been a number of reports of cutaneous adverse reactions to PP, particularly in patients affected by cystic fibrosis. A cellmediated immunopathogenic mechanism has been demonstrated (on the basis of patch-test or delayed intradermal-test positivity) in only two cases of ...

Delayed Hypersensitivity in vitro

Nature, 1967
DURING investigations of the effects of induced immune paralysis on delayed hypersensitivity in vivo and in vitro, evidence has been found1,2 for a diffusible factor which is released from the sensitive cells in contact with the antigen; this factor inhibits migration of cells from a normal lymph node explant.

Sulfonamide Hypersensitivity: Fact and Fiction.

Journal of Allergy and Clinical Immunology: In Practice, 2019
Sulfonamide antimicrobials are commonly reported as causing drug allergy and have been implicated in a variety of hypersensitivity reactions including immediate IgE-mediated reactions, benign T-cell-mediated rashes, and severe cutaneous adverse reactions

Radiocontrast Media Hypersensitivity: Skin Testing Differentiates Allergy From Nonallergic Reactions and Identifies a Safe Alternative as Proven by Intravenous Provocation.

Journal of Allergy and Clinical Immunology: In Practice, 2019
BACKGROUND Hypersensitivity reactions occurring within minutes after intravascular injection of iodinated radiocontrast media (RCM) are not rare and have been previously considered to be nonallergic.

Induction of ‘Delayed’ Hypersensitivity

Nature, 1962
IT is well known that the ‘delayed’ or ‘infectious’ type of sensitivity is induced in a normal organism, after contact with living or killed tubercle bacilli, but it is not passively transferred by means of serum or extracts of organs from ‘allergic’ animals.

Delayed Cutaneous Hypersensitivity Testing

Southern Medical Journal, 1982
The topic of delayed cutaneous hypersensitivity testing is reviewed. When skin tests are used to determine whether an individual is anergic, T cell immunity is evaluated. Skin testing can be used to determine the causative organisms of infection or to discover an immunologic deficiency state.

Delayed-Type Hypersensitivity Determination

2012
Delayed-type hypersensitivity responses in the skin (in the case of mice, in the foot pad) is used to assess cell-mediated immunity (CMI) in vivo. In the case of CMI to Helicobacter infection, the mice are given an injection of cultured Helicobacter organisms into the hind footpad, and induration is measured at the site of inoculation 24 h after ...

Delayed hypersensitivity in mice

Journal of Allergy, 1959
Abstract A new technique has been used to show that white mice can develop delayed hypersensitivity to tubercle bacilli. The technique consists of determining mouse lung densities after intravenous challenge with these bacilli, increased densities indicating the delayed allergic reaction. Aside from its high sensitivity, this method takes advantage of
