Abstract: Over the period 01/01/2013 until 31/08/2023, 13 907 total plasma IgE determinations were performed in the analytical laboratory of the Provincial Hospital in Opole.Among these determinations, there were 377 results below 2.0 U/l (in 279 patients), with the ultraextremely low results (<0.1 U/l), i.e. virtually undetectable, in 65 (in 44 patients). Original Research ArticleThe clinical picture of patients with the ultra-extremely low (undetectable) IgE (defined as <0.1 U/l)group 1 and the low IgE (defined as <2.0 U/l), divided into 4 ranges -0.1-0.5;0.6 -1.0; 1.1-1.5;1.6-1.9U/l -the group 2, 3, 4 and 5 respectively -was compared.Results: Health problems, defined as a syndrome of immune dysfunction, occurred more frequently in the groups with the ultra-low (virtually undetectable) IgE (<1.0) than in the group with the low IgE (0.1 -1.9) level, suggesting primary immune deficiency in these patients.This is also supported by the fact that the group 1 was younger than the others combined, and at the same time 'sicker' than the other groups.In this group -97 patients had serum IgE determinations at least twice during the analysed periodin 20 patients at least one of the repeated serum IgE results was higher than 10 U/l, in the remaining ones -in 17 patients it was in the range (2-10 U/l), in the remaining 60 patients the results of repeated serum IgE determinations did not exceed 2 U/l.Conclusions: For the purpose of talking about IgE deficiency as an indicator of a predisposition to neoplastic diseases, it would be necessary to carry out screening tests at least 3 times, in the identified age groups, e.g.every 10 years, from the age of 5 years.This would make it possible to determine -whether the IgE deficiency is primary or secondary.Primary, i.e. originally predisposing to the development of neoplastic diseases and being a part of primary immunodeficiency, or secondary -as a symptom of 'depletion' of the immune system.The incidentally detected low serum IgE needs to be verified. Keywords: Ultralow/undetectable IgE plasma level (<0.1 U/l); extremely low IgE plasma level (<2.0 U/l); low IgE plasma level.
