Correlation between serum levels of interleukin-4 and alexithymia scores in healthy female subjects: preliminary findings.

Objective: Some studies suggest that inaccuracy in recognizing and describing emotional states, combined with a highly descriptive mode of expression, as in alexithymia, may influence the immune response. We therefore investigated in healthy women the relationship between alexithymia and circulating levels of IL-1, IL-2 and IL-4.

Method: Seventeen mentally and physically healthy women aged between 20 and 25 years completed psychological questionnaires to assess alexithymia (Toronto Alexithymia Scale: TAS) and depressed mood (Hospital Anxiety and Depression Scale: HAD).

Is there a psychoneuroimmunological pathway between alexithymia and immunity? Immune and physiological correlates of alexithymia.

The term "alexithymia" was coined by Sifneos. It is characterised by a lack of words to express emotion (a: absence of; lexi: words; thymia: emotions, affects). Its characteristics were suggested to occur more frequently in individuals with so-called "psychosomatic disorders", but this is still a matter of controversy.
