Salivary Alpha-Amylase Activity Levels in Catatonic Schizophrenia Decrease after Electroconvulsive Therapy

PM482. SALIVARY ALPHA-AMYLASE (sAA) AS A BIOMARKER FOR THE RESPONSE OF THERAPY IN SCHIZOPHRENIA PATIENTS

s | 75 Methods: International, multicenter, retrospective, observational study. Outcomes presented are patient characteristics, reason for PP initiation and hospitalization data. Results: 84 patients were analyzed: Mean age (years) at first psychotic episode was 23.8(SD2.6), 23.9(SD2.6) at first antipsychotic treatment and 24.1(SD2.7, range 19–29) at PP initiation. Time between first antipsycho...

Salivary Alpha-Amylase Activity, a New Biomarker in Heart Failure?

Stress affects salivary alpha-Amylase activity in bonobos.

Salivary alpha-Amylase (sAA) is a starch digesting enzyme. In addition to its function in the context of nutrition, sAA has also turned out to be useful for monitoring sympathetic nervous system activity. Recent studies on humans have found a relationship between intra-individual changes in sAA activity and physical and psychological stress. In studies on primates and other vertebrates, non-inv...

Psychosocial Stress Increases Salivary Alpha-Amylase Activity Independently from Plasma Noradrenaline Levels

Salivary alpha-amylase activity (sAA) and plasma noradrenaline (NA) concentrations are often considered to be surrogate markers of sympathetic activation in response to stress. However, despite accumulating evidence for a close association between sAA and noradrenaline and other indicators of sympathetic activity, reliability and generality of this relation remains unclear. We employed the Trie...
