During metabolism studies of radiolabeled proteins in 126 participants four patients were suspected of being sensitive to potassium iodide (Kl) because they repeatedly developed urticaria and other symptoms after Kl administration. Two of the four patients suspected of Kl sensitivity and 10 control patients were orally challenged with Kl to document and characterize Kl sensitivity and to evaluate the possible association(s) of Kl sensitivity with urticaria, hypocomplementemia, and vasculitis. The Kl challenges in the two sensitive patients precipitated urticaria, angioedema, polymyalgias, conjunctivitis, and coryza. One of these two patients also developed a severe systemic illness characterized by fever, headache, peritonitis, episcleritis, and pneumonitis. The four sensitive patients were strikingly similar in that they exhibited hypocomplementemia and dermal vasculitis associated with chronic urticaria or systemic lupus erythematosus, suggesting that other patients with similar clinical features may be sensitive to Kl and that Kl may precipitate severe systemic illness in them.

A rare instance of contact-type urticaria resulting from an acquired sensitization to cephalosporin compounds in a chemist is reported. Patch tests elicited an immediate urticarial rather than a delayed contact-type response. Similar control tests to other antibiotics gave negative results. Although the patient's primary complaint was urticaria, prolonged or excessive contact with the cephalosporins caused coryza and dyspnea. Following transfer to another laboratory where the patient worked with other chemicals, there was no recurrence of symptoms.

We examined 70 patients reporting hypersensitivity reactions caused by latex articles. All patients suffered from urticaria, 36 from rhinitis, 31 from conjunctivitis, 22 from dyspnea, and 17 from systemic reactions, and four patients developed severe systemic complications during surgery. By means of inhalative challenge tests with powdered latex gloves, it could be demonstrated that the glove powder (cornstarch) obviously functions as a carrier for latex allergens, which then become airborne. Five of 18 patients undergoing such challenge tests demonstrated a significant increase of specific airway resistance; 17, acute rhinitis and/or conjunctivitis; and two, a systemic reaction. Sixty-two percent of the patients demonstrated specific IgE antibodies to natural latex, 58% to an irradiatively cross-linked, so-called, "hypoallergenic" latex preparation, and 46% to commercial-latex RAST disks (Pharmacia). No specific antibodies to cornstarch or a mixture of rubber chemicals were found. A good correlation (82%) exists between latex IgE RAST and latex skin prick test, as revealed in a subgroup of 45 subjects. By means of sodium dodecyl sulfate-polyacrylamide gel electrophoresis, the latex allergen appears to be a mixture of proteins in a molecular weight range from 10 to 67 kd.

Second-generation antihistamines are widely prescribed for the control of symptoms of allergic inflammation such as itchy hives, coryza, and itchy eyes. In rare circumstances, these drugs might provoke allergic inflammation. Hypersensitivity to bepotastine besilate, a second-generation antihistamine has never been reported. A 17-year-old schoolgirl, whose paroxysmal itchy hives had been controlled with bepotastine, experienced aggravation of the hives. An oral provocation test confirmed her hypersensitivity to bepotastine and cross-reactivity to levocetirizine. She showed no reaction to chlorpheniramine, ketotifen, or olopatadine among the 13 antihistamines tested. While searching for an antihistamine to control her itchy hives, we found that she also exhibited cross-reactivity to various antihistamines with different chemical structures from that of bepotastine, which is not predicted according to the chemical classification of antihistamines. We report a case of hypersensitivity to bepotastine besilate in a patient with chronic spontaneous urticaria.
