Polyethylene Glycol (PEG)-Induced Anaphylactic Reaction During Bowel Preparation
Barium enema is used to screen patients with gastrointestinal bleeding who do not want to undergo colonoscopy. Polyethylene glycol (PEG) is usually the bowel preparation of choice. Few allergic reactions from this product have been reported; these include urticaria, angioedema, and anaphylaxis. Reactions are thought to result from a small amount of PEG crossing the intestinal mucosa, which, in ...
متن کاملSkin reaction in antiviral therapy for chronic hepatitis C: a role for polyethylene glycol interferon?
In the past decade, different modalities of antiviral therapy have been adopted aimed at eradicating hepatitis C virus infection. Initially, interferon was used in monotherapy, then interferon combined with ribavirin and amantadine. Recently, interferon has been conjugated with polyethylene glycol to allow optimization of its pharmacokinetic properties and to improve its antiviral activity. Thi...
متن کاملPolyethylene glycol as a cause of anaphylaxis
BACKGROUND Polyethylene glycols (PEGs) or macrogols are polyether compounds and are widely used as additives in pharmaceuticals, cosmetics, and food. CASE REPORT We report on a Caucasian patient experiencing recurrent severe allergic reactions to several drugs. An extensive diagnostic workup including skin prick tests, intradermal tests (IDT) and a double-blind oral challenge was performed to...
متن کاملThe Diels-Alder reaction of C60 and cyclopentadiene in mesoporous silica as a reaction medium.
As a new organic reaction medium, a periodic mesoporous inorganic material was found to function as a "solid solvent" in a Diels-Alder reaction of C(60) with cyclopentadiene. This finding was supported by a concentration effect and a kinetic study of the reaction.
متن کاملEt3N/H2O: A green and inexpensive organocatalytic medium for efficient Baylis-Hillman reaction
A new organocatalyzed method is developed for Baylis–Hillman reactions of cyclohex-2-enone with various aromatic aldehydes in the presence of water and catalytic quantities of triethylamine. All reactions take place at room temperature and relatively good yields of various products are obtained within a time frame which does not exceed 24 hours. The mild reaction conditions used in the present ...
