RATIONALE: Mold is a well known cause of allergic rhinitis and asthma in children. No data, however, is available in the literature on mold allergy in Lebanon. The purpose of the study is to determine the sensitization prevalence to Alternaria sps, Aspergillus sps, Cladosporium sps and Penicillium sps in children with allergic rhinitis and/or asthma in Lebanon. METHODS: Children between the ages of 1 and 17 years who presented for allergic rhinitis and asthma were prick skin tested to common aeroallergens and to the following molds: Alternaria sps mix (alternata, longipes), Aspergillus sps mix (fumigatus, nidulans, niger), Cladosporium sps mix (cladosporoides,herbarum) and Penicillium sps mix (digitatum, expansum, notatum). All patients were tested with the same extracts. A skin prick test of 3mm larger than saline was considered positive. RESULTS: A total of 114 patients were included in the study. 51/114 had allergic rhinitis and 44/114 had asthma. 65% (75/114) of the patients were positive to at least one of the aeroallergen tested for. 19% of the patients were sensitized to Aspergillus sps, 7% to Cladosporium sps, 5% to Penicillium sps and 4% to Alternaria sps. 67% of the patients with mold allergy were younger than the age of 6 years. 90% of the mold allergic patients had allergic rhinitis and only 9% had hyperactive airway disease. CONCLUSIONS: The prevalence of mold sensitization in Lebanese children was 19%. The most commonly detected mold was Aspergillus. The majority of children were sensitized by the age of 6 years and they suffered mainly of allergic rhinitis.
