Insights
Geriatric patients with lower serum uric acid and higher urine pH may have a higher risk of urinary tract infections (UTI). Further research is needed to confirm these findings in larger populations.
Area of Science:
- Geriatric Medicine
- Nephrology
- Infectious Diseases
Context:
- Urinary tract infections (UTIs) are common in geriatric patients.
- Identifying risk factors for UTIs in this population is crucial for effective prevention and treatment.
Purpose:
- To investigate the association between serum uric acid, serum creatinine, urine pH, and the presence of pyuria in geriatric patients.
- To identify potential biomarkers for UTI risk in the elderly.
Summary:
- Serum uric acid levels were higher with lower urine pH in pyuria-negative patients compared to pyuria-positive patients.
- Serum creatinine levels were also relatively higher in pyuria-negative patients.
- Even after adjusting for serum creatinine, serum uric acid remained significantly higher in pyuria-negative males, suggesting a potential role in UTI risk.
Impact:
- The study proposes a hypothesis regarding the background factors of UTIs in geriatric patients.
- Highlights the need for further investigation into the relationships between serum uric acid, serum creatinine, urine pH, and pyuria in larger cohorts and experimental settings.
Abstract:
To identify risk factors of urinary tract infection (UTI) in geriatric patients, the levels of serum uric acid, serum creatinine, and urine pH were compared between pyuria-positive and -negative patients in a geriatric ward. The level of serum uric acid was higher with lower urine pH level in the pyuria-negative patients than in positive patients. The level of serum creatinine was relatively higher in the pyuria-negative patients than in the positive patients. Even after matching for serum creatinine, serum uric acid was significantly higher in the pyuria-negative male patients. The results in the present study proposed an interesting hypothesis about backgrounds for UTI in geriatric patients. The relationships among serum uric acid, serum creatinine, urine pH, and pyuria should be examined further in a larger population and in experimental studies.
