Insights
High uric acid levels (hyperuricemia) are independently linked to chronic kidney disease (CKD) in Bangladeshi adults. This study highlights a significant association, suggesting hyperuricemia as a potential risk factor for CKD.
Area of Science:
- Nephrology
- Public Health
- Metabolic Disorders
Background:
- Chronic kidney disease (CKD) is a global health issue and a major risk factor for cardiovascular disease.
- Hyperuricemia is associated with obesity, hypertension, cardiovascular disease, and diabetes, but its link to CKD requires further investigation.
Purpose of the Study:
- To determine the prevalence of CKD in Bangladeshi adults.
- To assess the relationship between hyperuricemia and CKD in this population.
Main Methods:
- Blood samples from 545 adults (≥18 years) were analyzed for serum uric acid (SUA), glucose, creatinine, and urea.
- Estimated glomerular filtration rate (eGFR) and CKD were calculated using serum creatinine levels.
- Multivariate logistic regression analyzed the association between SUA and CKD.
Main Results:
- The prevalence of CKD was 5.9%, with hyperuricemia found in 18.7% of participants.
- Mean SUA levels were significantly higher in participants with CKD compared to those without (7.1 vs. 5.7 mg/dL).
- CKD prevalence increased with higher SUA quartiles, and eGFR decreased significantly across these quartiles (p < 0.001).
Conclusions:
- Hyperuricemia shows an independent association with CKD in Bangladeshi adults.
- Further research is recommended to elucidate the underlying mechanisms connecting hyperuricemia and CKD.
Background And Aims:
Chronic kidney disease (CKD) is a public health concern worldwide and has been recognized as a significant risk factor for cardiovascular disease. The elevated level of uric acid (hyperuricemia) has been suggested to be associated with obesity, hypertension, cardiovascular disease and diabetes. However, there is limited information on the relationship between hyperuricemia and CKD. Therefore, this study aimed to estimate the prevalence of CKD and assess its relationship with hyperuricemia in Bangladeshi adults.
Methods:
In this study, blood samples were collected from 545 participants (398 males and 147 females) aged ≥ 18 years. Biochemical parameters such as serum uric acid (SUA), lipid profile markers, glucose, creatinine and urea were measured by colorimetric methods. The estimated glomerular filtration rate (eGFR) and CKD were determined based on serum creatinine levels with existed formula. Multivariate logistic regression analysis was performed to evaluate the association between SUA and CKD.
Results:
The overall prevalence of CKD was 5.9% with 6.1% in males and 5.2% in females. Hyperuricemia was prevalent in 18.7% of participants with 23.2% in males and 14.6% in females. An increasing trend of CKD prevalence was observed with increasing age in the groups. The mean eGFR level was significantly lower in male (95.1 ± 31.8 ml/min/1.73m2) than in female (109.3 ± 77.4 ml/min/1.73m2) subjects (p < 0.01). The mean level of SUA was significantly higher (p < 0.01) in participants having CKD (7.1 ± 1.9 mg/dL) than in participants without CKD (5.7 ± 1.6 mg/dL). A decreasing trend for eGFR concentration and an increasing trend for CKD prevalence was observed across the SUA quartiles (p < 0.001). In regression analysis, a significant positive association was found between hyperuricemia and CKD.
Conclusion:
This study showed an independent association between hyperuricemia and CKD in Bangladeshi adults. Further mechanistic studies are needed to explore the potential link between hyperuricemia and CKD.
