Time Averaged Uric Acid Is Associated With the Prognosis of IgAN in Females

Abstract Background IgA Nephropathy (IgAN) is one of the most common glomerular diseases. However, the effect of uric acid on the prognosis of IgAN is still unclear, especially between males and females. Therefore, the present study aimed to explore the role of hyperuricemia in IgAN patients and the differences in gender. Consequently, the study conducted a retrospective analysis of the prognosis of IgAN in patients from the General Hospital of Tianjin Medical University. Methods: A total of 1,022 patients with primary IgAN, diagnosed through renal biopsy were enrolled from the Department of Nephrology, General Hospital of Tianjin Medical University. However, after applying the exclusion criteria, only 463 patients remained and were regularly followed up in the hospital. In addition, the relationship between Time Average Uric Acid (TA-UA) and prognosis of IgAN was analyzed. Results: The findings showed that TA-UA was an independent risk factor for the prognosis of IgAN in the 463 patients studied (OR=1.752，95%CI=1.348-2.277，p＜0.001). Additionally, higher TA-UA values were associated with a faster progression of disease and worse prognosis (p < 0.05). Elevated TA-UA was also shown to be an independent risk factor for the progression of disease in female patients but not in their male counterparts (women: HR=1.998，95%CI=1.398-2.854，p＜0.001，men: HR=1.405，95%CI=0.869-2.274, p=0.166). Conclusion: Increased TA-UA is an independent risk factor for the progression of IgAN, especially in women.
