[Studies on cross reactivity to penicillins in patients with immediate allergic reactions caused by amoxicillin].

In this study we have explored the presence of cross reactivity to penicillin and ampicillin in patients with immediate allergic reactions caused by amoxicillin. Skin test results with amoxicillin were positive in 66.66% and in the remaining 33.

CAST-ELISA test--a new diagnostic tool in pollen allergy.

We have applied a recently developed method called CAST-ELISA to evaluate the degree of leukocyte stimulation by specific allergen. This method is based on the measurement of sulfidoleukotriene levels in supernatants taken from previously stimulated peripheral blood leukocytes by specific allergen in the presence of interleukin 3.23 patients with pollinosis entered the study.
