Mastocytosis is a neoplasm characterized by an accumulation of mast cells in various
organs and increased risk for severe anaphylaxis in patients with concomitant allergies …

At present, iodinated contrast media (ICM) are mostly non-ionic, have low osmolality, and
are safe. Even if adverse drug reactions (ADRs) occur, most are chemo-toxic symptoms and …

Immediate and nonimmediate hypersensitivity reactions to iodinated contrast media (ICM)
have been reported to occur in a frequency of about 0.5%‐3% of patients receiving nonionic …

Background Multicenter studies may be required for establishing guidelines for safe usage
of iodinated contrast media (ICM). Purpose To identify the prevalence, patterns, risk factors …

Background It is unclear whether steroid premedication is an effective means of preventing
repeat allergic-like reactions in high-risk patients with a previous allergic-like reaction to …

Background The recurrence of hypersensitivity reaction (HSR) to low-osmolar iodinated
contrast media (LOCM) remains challenging despite premedication and substitution of the …

Purpose To evaluate premedication protocols involving administration of antihistamine and
multidose corticosteroid that have been widely used in prevention of recurrent …

Background With the widespread use of gadolinium-based contrast agents (GBCAs), the
incidence of allergic-like hypersensitivity reactions (HSRs) to GBCAs is increasing …

Objectives We aimed to meta-analytically compare the incidence of acute adverse reactions
(AARs) to nonionic iodinated contrast media (ICM) according to the type of ICM in patients …

Background There are few data on the relationship between acute hypersensitivity reactions
and the dose and injection rate of iodinated contrast material for CT. Purpose To determine …
