|Allergen Data Collection:
Watermelon (Citrullus lanatus)
|Authors in alphabetical order [contact
Watermelon is a member of the gourd family, Cucurbitaceae, which
is cultivated in the Mediterranean area as well as in tropical and subtropical
areas worldwide. Allergy to watermelon is most frequently associated with
symptoms of the oral allergy syndrome. Nevertheless cutaneous and respiratory
symptoms, and even anaphylaxis have been reported. A taxonomic association
of sensitization is likely between different members of the Cucurbitaceae
family, which also includes melon, cucumber, pumpkin,and zucchini). Moreover,
sensitization to ragweed pollen is high in watermelon allergic subjects.
Several IgE-binding proteins with molecular masses between 15 and 90 kDa have been identified. Cross-reactivities of watermelon to cucumber, zucchini, carrot, celery, and ragweed pollen have been documented.
The present data collection reviews detailed information on the prevalence and symptoms of allergy to watermelon as well as diagnostic features, and the occurrence of cross-reactivities in tabular form.
The reference lists of the Allergen Data Collections are based mainly on searches of Medline and FSTA (Food Science & Technology Abstracts) databases up to the related dates of publication. The scientific rigor of the studies listed is variable and not subject of critique or evaluation by the authors or the editor of the Allergen Data Collections. The reader should be aware of considerable problems in comparing data from different studies (eg. patient cohorts, diagnostic performances, possible flaws in allergen preparations and methodologies for allergen characterization) and is encouraged to review the original publications.
