Summary

Prolactin is a one of the stress hormones, like the growth hormone, ACTH, cortisol and catecholamins. Among its wide range of functions is the important role of controlling the immune response which is, unlike in the case of cortisol, of stimulatory nature. For this activity, it is monitored as a factor influencing the progress and course of autoimmune diseases. The authors of the paper monitored prolactin response to stress in a normal stress situation, i.e. blood collection. A significant difference was detected between the levels of prolactin in 3 successive blood collections in 30 minute intervals (P < 0.001). Prolactin responded by a prompt increase in the serum level, followed by a relatively fast linear decrease. There was no difference in the response between the SLE and RA patient groups and the healthy population. Therefore we conclude that this is a normal reaction of the organism because acute response to stress in patients with autoimmune diseases is the same as in healthy persons.
