Summary
Serum uric acid may slow disease progression in multiple system atrophy (MSA). Higher uric acid levels correlated with slower annualized Unified Multiple System Atrophy Rating Scale changes in MSA patients.
Area of Science:
- Neuroscience
- Biochemistry
Background:
- Mitochondrial dysfunction and oxidative stress are implicated in multiple system atrophy (MSA) pathogenesis.
- Understanding factors influencing MSA progression is crucial for patient care.
Purpose of the Study:
- To investigate the relationship between serum uric acid levels and disease progression in patients with multiple system atrophy (MSA).
Main Methods:
- Evaluated 52 patients with MSA.
- Assessed disease progression using changes in annualized Unified Multiple System Atrophy Rating Scale (UMSARS) scores.
- Analyzed the influence of serum uric acid levels on UMSARS score changes.
Main Results:
- Patients in the highest uric acid quartile showed significantly slower UMSARS progression compared to the lowest quartile.
- Serum uric acid levels demonstrated a significant negative correlation with annualized UMSARS changes (r = -0.40, P = .004).
- Multiple linear regression confirmed serum uric acid concentration as a significant predictor of UMSARS changes (β = -2.687, P = .011).
Conclusions:
- Serum uric acid may function as a potential disease modifier in multiple system atrophy (MSA).
- These findings highlight the potential role of uric acid in modulating MSA pathogenesis.

01:22Lysosomal Hydrolases
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
01:27Pharmacogenetics of Phase II Enzymes: N-acetyltransferase, Thiopurine S-methyltransferase, UDP-glucuronosyltransferase
Phase II biotransformation reactions are essential for detoxifying and eliminating xenobiotics, including many pharmaceutical compounds. These reactions typically involve conjugation, the covalent attachment of polar endogenous groups such as glucuronic acid, sulfate, methyl, or acetyl moieties to functional groups introduced during Phase I metabolism. The resulting conjugates are more water-soluble, enabling efficient renal or biliary excretion.The major classes of Phase II enzymes include...
