Abstract:
Objective:To explore the differences in renal pathological characteristics between Li and Han patients with lupus nephritis (LN) in Hainan region.Methods:A retrospective analysis was conducted on the renal pathological data of 135 patients with systemic lupus erythematosus (SLE) who underwent renal biopsy in the Department of Nephrology and Rheumatology, Haikou Affiliated Hospital of Central South University Xiangya School of Medicine from January 2013 to December 2023. They were divided into Li ( n=22) and Han ( n=113) patients according to their ethnicity. The SLE disease activity index (SLEDAI-2000), renal pathological classification, glomerulosclerosis, and tubulointerstitial lesions of LN patients from different ethnicities were analyzed. Results:During the follow-up period, there was no statistically significant difference in the incidence rate of end-stage renal disease in LN patients between Li nationality and Han nationality (13.6% vs 7.9%, P=0.656). The SLEDAI-2000 score of Li ethnic LN patients was mainly mild and moderate activity, while Han ethnic LN patients were mainly moderate and severe activity. There was no statistically significant difference in SLEDAI-2000 between the two groups ( P=0.577). The pathological subtypes of LN patients in both Li and Han ethnic groups are mainly Ⅳ/Ⅳ+ Ⅴ. There was no statistically significant difference between the two groups in different pathological subtypes of Ⅰ, Ⅱ, Ⅲ/Ⅲ+ Ⅴ, Ⅳ/Ⅳ+ Ⅴ, and Ⅴ (all P>0.05). There was no statistically significant difference in AI and CI between the two groups (all P>0.05). There was no statistically significant difference in the proportion of glomerulosclerosis between Li and Han LN patients ( P>0.05). However, the acute and chronic renal tubulointerstitial lesions in Li ethnic LN patients are more severe than those in Han ethnic group ( P=0.008 and P=0.038). Conclusions:The incidence rate of end-stage renal disease in LN patients of Li nationality is higher than that in Han nationality. The acute and chronic renal tubular and interstitial lesions in LN patients of Li nationality are more serious than those in Han nationality.
