Abstract
OBJECTIVES
The objective of the study was to explore the causes and predictors of mortality in a cohort of LN with LN in southern Hunan, China.
METHODS
We analyzed 236 patients with biopsy-proven LN during 2010-2018. Demographic data, laboratory data, SLEDAI scores, treatment strategies, and comorbidity were collected. Cox regression analysis was carried out to determine the independent predictors of mortality.
RESULTS
The patients had mean disease duration of 67.9 ± 28.2 months. Class IV LN was the predominant biopsy class within the cohort (38.1%). After 1 year therapy, the majority of patients achieved complete remission (72.9%) and 44 (18.6%) patients achieved partial remission. The 5- and 10-years survival rates for our cohort were 94.4 and 85.2%, respectively. There were 18 deaths (7.6%), of which the main causes were infection (50%) alone and cardiovascular diseases (27.8%). Independent predictors of mortality in our cohort were: platelet-to-neutrophil ratio (PNR) [hazard ratio (HR) 5.910; confidence interval (CI) 1.253-27.875], onset age (HR 1.090; CI 1.035-1.147), and SLEDAI scores (HR 1.258; CI 1.068-1.482).
CONCLUSION
We firstly revealed that PNR might be a promising predictor of mortality and reported the causes and prognostic predictors of mortality in LN from southern Hunan, China.
