Ophthalmologists frequently use mydriatics both for diagnosis (retinal exploration, refraction tests) and for treatment. Cyclopentolate is used to induce quick and successful mydriasis for pediatric eye examination. Hypersensitivity reaction to cyclopentolate is very uncommon, especially in children. We report the case of a child who experienced a hypersensitivity reaction to cyclopentolate dur...

Background Skin tests are important in the investigation of hypersensitivity drug reactions (HDR), particularly when betalactams are involved. However, the sensitivity decreases with time. It has been described that skin tests become negative about five years after a betalactam hypersensitivity reaction. We report a patient with persistence of a positive skin test twenty five years after an ana...

Allergic reactions against GH are rare, and usually represented by the hypersensitivity type I (IgE-mediated). This type of reaction can be treated by desensitization. In this case report, we present a patient showing an allergic reaction soon after starting GH therapy mediated by immune complex (hypersensitivity type III reaction). In this condition, the attempt to perform the desensitization ...

Anticonvulsants have long been recognized as a cause of hypersensitivity reactions. Phenytoin hypersensitivity can be traced to 1916, when phenylethylhydantoin (phenytoin sodium), which was used to treat children with Sydenham chorea, was found to induce a hypersensitivity reaction. Phenytoin was then known as a “nerve sedative,” and the hypersensitivity reaction, “nirvanol sickness,” resolved ...

Background A role for drug-specific T cells has been demonstrated in many instances of drug hypersensitivity. In the case of -lactam antibiotics, such as flucloxacillin, we have shown that drug-protein conjugates are present in the plasma of all patients treated with this antibiotic, however only a small subset of patients develop hypersensitivity. Similarly, when a strong HLA association to dr...

247 Im ages procedural pain has been associated with the use of a filler containing HA and lidocaine [3]. The present report is the first case of a severe angioedema-type acute hypersensitivity reaction to a filler containing HA and lidocaine. In the present case, this acute reaction could be secondary to HA, lidocaine, EMLA cream, or simply due to the repeated punctures of the needle. Although...

The effect of ubenimex on graft-versus-host reaction and delayed cutaneous hypersensitivity in mice was studied. Ubenimex enhanced the graft-versus-host reaction in a dose range from 0.005 to 0.5 mg/kg. Ubenimex inhibited the aging-caused decrease of delayed cutaneous hypersensitivity to oxazolone and the efficacy was greater with older mice. Ubenimex also inhibited mitomycin C and L1210-caused...

Major toxicities More common: Nausea, vomiting, fever, headache, diarrhea, rash, and anorexia. Less common (more severe): Approximately 5% of adults and children receiving ABC develop a potentially fatal hypersensitivity reaction. Symptoms include fever, fatigue , malaise, nausea, vomiting, diarrhea, and abdominal pain or respiratory symptoms such as shortness of breath. Physical findings inclu...

BACKGROUND Like nearly all systemic cancer therapies, monoclonal antibodies are associated with hypersensitivity reactions. This article reviews the characteristics and management of hypersensitivity reactions to monoclonal antibodies and commonly used chemotherapy agents. METHODS MEDLINE was searched for recent studies and reviews pertaining to hypersensitivity reactions with monoclonal anti...

Fluoroquinolones are widely used in the management of infectious diseases, and are generally safe and well tolerated. However, immediate hypersensitivity reactions, including anaphylactic reactions, have been reported. We present here a case of anaphylactic shock in a 26-year-old man following intravenous levofloxacin administration. Skin tests confirmed an immediate hypersensitivity reaction t...
