Gut Microbiota Alterations in Patients with Panic Disorder: A Case-Control Study.

Area of Science:

• Microbiome Research
• Neuroscience
• Gastroenterology

Background:

• Gut microbiota influences the gut-brain axis, impacting anxiety and stress.
• Parkinson's disease (PD) may involve gut microbial alterations.
• Understanding microbial diversity in PD phases is crucial.

Purpose of the Study:

• Compare gut microbiota diversity in acute PD, remission PD, and healthy individuals.
• Analyze metabolic pathway differences in the gut microbiota across these groups.
• Investigate the role of gut-brain axis in Parkinson's disease pathophysiology.

Main Methods:

• Diagnosis via Mini-International Neuropsychiatric Interview (M.I.N.I).
• Gut microbiota composition analyzed using 16S rRNA gene sequencing.
• Clinical assessments included BMI, SF-36, HAM-A, MADRS, C-SSRS, and STAI.

Main Results:

• Lower microbial richness observed in acute PD compared to controls and remission PD.
• Enrichment of Ruminococcus gnavus group in acute PD.
• Predicted functional differences linked to steroid biosynthesis and innate immune signaling.

Conclusions:

• Distinct gut microbial signatures are associated with Parkinson's disease.
• Metabolic and inflammatory pathways are implicated in PD pathophysiology via gut microbiota.
• Gut-brain axis interactions are key in PD.
