[Serum serotonin level in patients with depression and panic attacks]

Area of Science:

• Neuroscience
• Biochemistry
• Psychiatry

Context:

• Investigated serum serotonin levels (SSL) in patients diagnosed with depression and panic attacks (PA).
• Included a control group of non-depressed individuals with or without PA and autonomous nervous system dysfunction.
• Utilized the Enzyme-Linked Immunosorbent Assay (ELISA) method for SSL quantification.

Purpose:

• To explore the relationship between SSL and the severity of depression.
• To determine if SSL can serve as a biomarker for depression severity.
• To assess correlations between SSL and other clinical signs like anxiety and autonomic nervous system parameters.

Summary:

• A significant positive correlation (r = 0.82, P < 0.05) was found between increased SSL and depression severity, assessed by the Beck Depression Inventory (BDI).
• SSL values were significantly higher in mild (203.41 ± 26.47 ng/ml) and severe (438.58 ± 36.31 ng/ml) depressed patients compared to controls (72.6 ± 10.06 ng/ml).
• No significant correlation was observed between SSL and anxiety levels or autonomic nervous system parameters.

Impact:

• Suggests SSL as a potential objective marker for verifying depression severity.
• Provides quantitative data on SSL differences across depression severity levels.
• Highlights the specific link between serotonin and depressive symptom intensity in this patient cohort.
