Abstract
BACKGROUND:

IgE may be considered the hallmark of allergic disorders. It is easily detected in serum and can be measured as total IgE and as allergen-specific IgE. In fact, the serum IgE assay is used to diagnose an allergy.

AIM:

The aim of this study is to evaluate, investigate and present the distribution of total serum IgE levels, determined with UniCap system, in food-allergy suspected patients in a Republic of Macedonia.

MATERIAL AND METHODS:

In this study we analyzed retrospectively 8898 consecutive patients that were admitted for allergy testing at the Institute of Immunobiology and Human Genetics during the ten year period between 01.01.2001 and 01.01.2011. Total IgE levels in patient sera were detected with the in vitro system UniCAP100 (Pharmacia, Uppsala, Sweden).

RESULTS:

When we analyzed the number of patients according to the total IgE groups, we noted that most of the patients have normal levels of total IgE in serum. However, we also discovered a group of patients with elevated levels of total IgE that are greater than 200 kU/L. The average concentration of total serum IgE is higher in women in the age group 6 (6-7 years), followed by a steep decrease in the age group 9 (9-10 years), and after that the average concentrations of total IgE were mostly constant with the exception of a partial increase in the age group 21 (65-69 years). For men, the average serum concentrations of total IgE were highest in the age group of 6 (6-7 years), which was significantly higher than the average concentrations of total IgE in all other age groups.

CONCLUSION:

The large number of enrolled patients, a particular strength of this study, revealed that average concentrations of total IgE in men are higher than in women and that total IgE did not decrease with age. On the contrary, increased total IgE levels were found in patients aged 65 and 69 of both genders. We continue our work with analyses of the specific IgE antibodies values toward food and the correlation with total IgE values.
