Late onset reactions following venom immunotherapy and venom skin tests.

Abstract

This report describes patients who had late onset reactions following venom immunotherapy and venom skin tests. Six adult patients had symptoms of fatigue, malaise, fever, headache, and joint ache, starting four to six hours after venom immunotherapy and lasting up to four days. Two of the patients had prolonged reactions at or adjacent to the skin test sites. All of these patients had a history of venom anaphylaxis; four had severe cardiovascular symptoms. All received yellow jacket venom immunotherapy and four honeybee venom immunotherapy. In four patients, the reactions occurred following small venom doses, 0.1 to 2 micrograms. Two patients reacted after maintenance doses of 50 micrograms. There was no relationship to the serum IgE or IgG antibody titers. All but one patient had serum venom-specific IgE but the titers covered a wide range. Serum venom-specific IgG was present in four patients. There was no response in lymphocyte culture to bee venom stimulation in two patients. Two of these patients stopped venom immunotherapy; one had reached the maintenance dose. In three patients, prophylactic parenteral steroids have ameliorated the reactions. After a temporary dose reduction, the sixth patient is now asymptomatic. A seventh patient developed asthma, 12 hours following a maintenance dose of 50 micrograms of yellow jacket venom. Concomitant steroid administration has effectively prevented the reaction. Another patient, a 6-year-old boy, developed fever, edema of the face and lips, erythema of the leg, and a large, tender right inguinal node eight hours following venom skin tests.(ABSTRACT TRUNCATED AT 250 WORDS)
