SUMMARY
We report the case of a 36-year-old male pharmaceutical laboratory worker. On handling Spagulax® sachets whose content is a laxative called Plantago ovata, he immediately presented hinoconjunctivitis. Methods. Specific allergy study included SDS-PAGE with Western Blot and specific nasal challenge to Plantago ovata extract. Results. Prick by prick for Spagulax® was negative. Total IgE: 126.5 U/mL. Western Blot recognized two proteins of 15 and 20 kDa in the extract of Plantago ovata and three proteins of 15, 18 and 50 kDa in the extract of Plantago lanceolata. Conclusions. We present a case of occupational allergy due to inhalation of and/or contact with Plantago ovata seeds.
