Abstract

BACKGROUND:

Several hypotheses have been postulated to explain the etiopathogenesis of chronic fatigue syndrome (CFS). Among these, immunologic dysfunction has been proposed. Up to 30 % of these patients have a history of allergic disease. The aim of this study was to investigate whether allergic sensitization is higher in patients with CFS than in the general population.

METHODS:

Twenty-five patients with CFS and 20 controls were evaluated. A clinical history for allergy was taken and immediate hypersensitivity tests were performed.

RESULTS:

Twelve patients (48 %) and eight controls (40 %) had a family history of atopy. Personal histories of atopy were as follows: rhinoconjunctivitis: 12 patients (48 %), seven controls (35 %); asthma: five patients (20 %), two controls (10 %); food allergy: three patients (12 %); atopic dermatitis: two patients; contact dermatitis: two patients. No statistically significant differences were found between the groups in any of the variables (p > 0.05). In the CSF group, 3.4 % (15/441) of the inhalant prick tests were positive, and in the control group 3.8 % (16/420) were positive. None of the tests for hypersensitivity to food or latex were positive.

CONCLUSIONS:

In our study atopy was not more prevalent in patients with CFS than in healthy controls, although the CSF group tended to report more respiratory symptoms and drug allergies.
