Abstract:
Objective:To investigate the clinical value of dynamic detection of lymphocyte subsets and blood cell counts in management of patients with lupus nephritis (LN).Methods:The clinical data of 65 patients with primary LN admitted in Affiliated Hospital of Qingdao University from January 2015 to April 2021 were retrospectively analyzed. According to the stage of disease progression and medications used,LN patients were classified into primary active phase,post-induction therapy phase,and maintenance therapy phase. The changes in lymphocyte subsets were monitored,and the relationship of lymphocyte subsets and blood cell count ratios with lupus activity and infection events was evaluated.Results:The decrease of CD4 +T lymphocyte and NK cell counts were negatively correlated with the activity of systemic lupus erythematosus (SLE)( r=-0.67,-0.33, P<0.01),while CD8 +T lymphocyte,B cell counts,neutrophil/lymphocyte ratio (NLR),platelet/lymphocyte ratio (PLR),and monocyte/lymphocyte ratio (MLR) were positively correlated with the SLE activity( r=0.38,0.26,0.34,0.26,0.29, P<0.05). The area under ROC curve (AUC) of CD4 +T lymphocyte count in predicting the occurrence of infection in LN patients was the highest (0.89); taking 247.50 cell/μl as cutoff value,the sensitivity and specificity were 81.25% and 87.50%,respectively. The combination of CD4 +T lymphocyte with CRP increased the predicting value for the occurrence of infection. Conclusion:Dynamic detection of blood lymphocyte subsets and blood cell counts can reflect SLE activity and the occurrence of infection in LN patients. Among these indicators the CD4 +T lymphocyte has the highest predictive value for the occurrence of infection,and the combination of the CD4 +T lymphocyte count with CRP level can further improve the predicting value.
