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

161 patients.
- What was actually found?
Pollen-linked, mostly oral symptoms.
- How large was the observed effect?
Not applicable.

People with pollen allergy may react to melons; others need not avoid them.
- What are the study's limitations?
Selected patients.
- What does it say about Elawady's specific claim?

2. Research question
What are the clinical characteristics of melon allergy?
3. Study design and population
- Study design
- Case-control study – Clinical case-control description of melon-allergic patients vs pollen-allergic controls
- Population
Melon-allergic patients (oral challenge-confirmed) and pollen-allergic controls
- Country
Spain (Madrid)
- Period
not stated in abstract
- Sample size
161 (66 melon allergy, 95 controls)
- Inclusion and exclusion criteria
not stated in abstract
4. Methods and endpoints
- Exposure / intervention
Melon allergy
- Comparator
Pollen allergy without melon allergy
- Endpoints
Symptoms, cross-sensitisations
- Statistical methods
Odds ratios
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
- Orienting tool
- none applicable
- Type of assessment
- simplified assessment (abstract only)
- Full formal assessment
- no
- Overall risk of bias
- some concerns
- Rationale
Referral population.
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.
