AI Article Synopsis
- * Results showed that SUA levels significantly decreased during acute flares, while urinary uric acid excretion and fractional excretion of uric acid increased, suggesting a link between these changes.
- * The findings indicate that inflammatory factors and bioactive free glucocorticoids may be important in the reduced SUA levels observed during acute gout episodes.
Article Abstract
Objective: By studying the changes of serum uric acid (SUA) in acute stage and remission stage of gouty arthritis, we aimed to explore the relationship between the changes of SUA level and free glucocorticoids and inflammatory factors.
Methods: A prospective, longitudinal study was conducted on 50 acute gout patients in the dedicated gout clinic of the Affiliated Hospital of Qingdao University. Blood and 24-hour urine samples were collected during the acute phase and two weeks after the initial visit. Patients with acute gouty arthritis were treated primarily with colchicine and nonsteroidal anti-inflammatory drugs.
Results: A total of 32 patients completed the two-week follow-up trial. SUA levels were significantly downregulated during the acute flare than after the flare (464.14 ± 90.97 . 527.36 ± 86.90 μmol/L, < 0.001). The 24-hour fractional excretion of uric acid (24 h FEur) (5.54 ± 2.82% . 4.68 ± 2.83%, < 0.001) and 24-hour urinary uric acid excretion (24 h Uur) (663.08 ± 249.48 μmol/L . 540.87 ± 263.18 μmol/L, = 0.001) increased significantly in patients during the acute phase. The percent change in SUA was associated with those in 24 h FEur and C-reactive protein. Meanwhile, the percent change in 24 h Uur was associated with those in 24-hour urinary free cortisol, percent change in interleukin 1β and interleukin 6.
Conclusion: Decreased SUA level during the acute gout flare was associated with increased excretion of urinary uric acid. Inflammatory factors and bioactive free glucocorticoids may play significant roles in this process.

Background: Serum uric acid (SUA) was a predictor of cognitive function. The association of SUA/serum creatinine ratio (Scr), which represents renal function-normalized SUA and cognitive function is unknown.
Objective: This study investigated the association of the SUA/Scr with cognitive function and the potential mediation effect of inflammation in the above relationship.

The detection of biomarkers is crucial for assessing disease status and progression. Uric acid (UA), a common biomarker in body fluids, plays an important role in the diagnosis and monitoring of conditions such as hyperuricemia, chronic kidney disease, and cardiovascular disease. However, the low concentration of UA in non-invasive body fluids, combined with numerous interfering substances, makes its detection challenging.

Background: Metabolic syndrome (MetS) was associated with an increased incidence of mild cognitive impairment (MCI) and progression to dementia. However, little is known about why this occurs. This study was to examine the correlation between the MetS indicators and cerebrospinal fluid (CSF) pathological protein biomarkers to investigate this mechanism.
