Multiple sclerosis (MS) is an autoimmune disease affecting the central nervous system.
An impaired hypothalamopituitary axis and stress reactivity have extensively been discussed without convincing experimental evidence.
We choose a standardized acute psychological stressor to determine whether MS patients show altered endocrine and immune responses to stress.
In 35 relapsing-remitting MS patients we found elevated baseline levels for catecholamines, prolactin, and IL-6 compared to 15 healthy controls.
All neuroendocrine parameters declined during the stress intervention in MS as well as in stress-exposed controls.
But only prolactin showed a significantly larger decline in stressed MS patients versus controls.
During exposure to the stress we found no significant changes in serum levels of IL-6, IL-6 receptor, or TNF-alpha in either MS patients or controls after stimulation of a whole blood culture.
An altered neural immune signaling in relapsing-remitting MS patients
during acute experimental stress could not be proven for the parameters
