The Role of Serum 5-HIAA as a Predictor of Progression and an Alternative to 24-h Urine 5-HIAA in Well-Differentiated Neuroendocrine Neoplasms [PDF]

open access: goldBiology, 2021
Our aim was to investigate the clinical utility of serum 5HIAA for disease surveillance and diagnostic purposes in a cohort of patients with well-differentiated neuroendocrine neoplasms (WD-NENs).

Enhancing immunotherapy efficacy in NSCLC through the combined use of phenelzine and Akkermansia muciniphila to regulate gut microbial metabolite 5-HIAA [PDF]

open access: goldJournal for ImmunoTherapy of Cancer
Background Improving the efficacy of anti-programmed death 1 (PD-1) monoclonal antibody (mAb) therapy remains a major challenge for cancer immunotherapy in non-small cell lung cancer (NSCLC). Gut microbial metabolites can influence immunotherapy efficacy.

Biomarker of urinary 5-HIAA as a valuable predictor of acute appendicitis [PDF]

open access: goldPractical Laboratory Medicine, 2021
Background: Serotonin-containing cells are abundantly found in the appendix. Studies have shown that acute appendicitis is likely to be characterized by altered urinary 5-hydroxyindole acetic acid (5-HIAA), an active serotonin metabolite. The aim of this

Measurement of urinary 5-HIAA: correlation between spot versus 24-h urine collection [PDF]

open access: yesEndocrine Connections, 2019
Background: The 24-h urinary output of 5-hydroxyindoleacetic acid (5-HIAA) is used to monitor disease progression and treatment responses of neuroendocrine neoplasms (NENs).

Gender-Specific Effect of 5-HT and 5-HIAA on Threshold Level of Behavioral Symptoms and Sex-Bias in Prevalence of Autism Spectrum Disorder [PDF]

open access: yesFrontiers in Neuroscience, 2020
Platelet hyperserotonemia in a subset of Autism Spectrum Disorder (ASD) probands, efficacy of selective serotonin reuptake inhibitors (SSRIs) in reducing behavioral deficits and gender-bias in normal serotonin (5-hydroxy tryptamine or 5-HT) synthesis ...

Elevated Cerebrospinal fluid 5-hydroxyindoleacetic acid in Macaques Following Early Life Stress (ELS) and Inverse Association with Hippocampal Volume: Preliminary Implications for Serotonin-Related Function in Mood and Anxiety Disorders [PDF]

open access: yesFrontiers in Behavioral Neuroscience, 2014
Background: Early life stress (ELS) is cited as a risk for mood and anxiety disorders, potentially through altered serotonin neurotransmission. We examined the effects of ELS, utilizing the variable foraging demand (VFD) macaque model, on adolescent ...

The diagnostic utility of urinary 5-HIAA and leucine-rich alpha-2 glycoprotein in acute appendicitis: a narrative review [PDF]

open access: yesFrontiers in Medicine
BackgroundAcute appendicitis (AA) remains diagnostically challenging despite its global prevalence. Current methods rely on clinical scoring systems (e.g., Alvarado score) and imaging (US, CT, and MRI). Urinary biomarkers like 5-hydroxyindoleacetic acid (
