Abstract
Objective
This study was performed to investigate the relationship between hemoglobin, albumin, lymphocyte and platelet (HALP) score and Oxford classification severe tubular atrophy/interstitial fibrosis (T2) in IgA nephropathy (IgAN).
Methods
The clinical data and pathological findings of patients with IgA nephropathy diagnosed through renal biopsy at Hangzhou Hospital of Traditional Chinese Medicine between June 1, 2019 and May 31, 2022 were retrospectively collected and analyzed. The HALP score was calculated as hemoglobin (g/L)× albumin (g/L)× lymphocytes (/L)/ platelets (/L). According to the quartile of HALP scores in the study population, the subjects were divided into four groups: Quartile 1 (< 30.72), Quartile 2 (30.72-39.97), Quartile 3(39.97-53.25) and Quartile 4(>53.25). According to the extent of tubular atrophy/interstitial fibrosis, patients were categorized into mild to moderate injury (T0+T1, ≤50%) and severe injury (T2, > 50%). The relationship between HALP score and severe tubular atrophy/interstitial fibrosis was investigated using Spearman's rank correlation coefficient, logistic regression analysis, restricted cubic splines (RCS), and receiver operating characteristic (ROC) curve analysis.
Results
A total of 895 patients diagnosed with IgAN were included in this study, with an average age of 40.97±12.261 years. Among them, 384 (42.9%) were male and 61 (6.8%) exhibited severe tubular atrophy/interstitial fibrosis. Multifactorial logistic regression analysis revealed that HALP independently influenced T2 (OR=0.952, 95%CI: 0.923-0.982, P=0.002). Compared to Quartile 1, patients in Quartile 4 exhibited a significantly reduced risk of T2 (OR=0.205, 95%CI: 0.058-0.722, P=0.014). Restricted cubic splines analysis revealed a linear inverse association between HALP and T2 risk (nonlinear P=0.896). Furthermore, the receiver operating characteristic curve demonstrated that HALP possessed predictive value for T2 (AUC=0.693, Jorden index = 0.324), and the cut-off value of HALP score is 36.54.
Conclusion
The risk of severe renal tubular atrophy/interstitial fibrosis is higher in IgAN patients with low HALP. HALP less than 36.54 May reduce the risk of severe tubular atrophy/interstitial fibrosis.
