Overview

Figueredo E et al.. Ann Allergy Asthma Immunol 2003 · PMID 14533664 · DOI 10.1016/s1081-1206(10)63534-x

All 66 melon-allergic patients also had pollen allergy; symptoms were mostly in the mouth and none had anaphylaxis.

Does the study support the specific claim? Partly · Methodological quality: moderate

5. Actual results

Results

All melon-allergic patients had oral symptoms; 19.7% extraoral; none had generalized urticaria or anaphylaxis; all were pollen-allergic; up to 62% allergic to peach; 23% latex sensitisation; higher asthma prevalence (OR 2.13).

Absolute risks

not reported

Authors' conclusion

Melon allergy is linked to pollen allergy (100%), allergy to unrelated fruits and latex sensitivity.

6. Strengths

  • Challenge-confirmed diagnoses

7. Weaknesses

  • Single allergy centre; selected patients

8. Risk of bias

9. Assessment of the statistical interpretation

Descriptive ORs; no CIs in abstract.

10. Relevance to the specific claim

Confirms cucurbit cross-allergy exists in pollen-allergic people, with mainly mild oral symptoms.

11. Independent contrary findings

none

12. Transferability to Germany and Europe

European.

13. Overall methodological judgement

Supports the claim for a pollen-allergic subgroup; no basis for general avoidance.
