Abstract:
Objective:To analyze the clinical characteristics of patients with Epstein-Barr virus(EBV)-associated hemophagocytic lymphohistiocytosis(HLH)with acute kidney injury(AKI).Methods:EBV-HLH patients who were hospitalized in our hospital from January 2014 to December 2020 were collected,and their clinical characteristics,treatment,concurrent acute kidney injury and prognosis were retrospectively analyzed.Results:In this study,the incidence of AKI complicated by EBV-HLH was 65.5％,and the 28-day mortality rate was 15.3％.Compared with non-AKI group,patients in the AKI group had higher levels of bilirubin,lactate dehydrogenase,creatinine,urea nitrogen,and β2-microglobulin(β2-MG),poorer coagulation,and lower soluble IL-2 receptor(sCD25).Patients in the AKI group had a higher proportion of chemotherapy,transplantation,mechanical ventilation,and the application of vasoactive medications,and were hospitalized for longer periods of time,with higher in-hospital mortality rates and 28-day mortality rates.Patients in the AKI group were analyzed in subgroups according to the Kidney Disease Improving Global Outcomes(KDIGO)classification,and the levels of leukocytes,bilirubin,albumin,creatinine,urea nitrogen,β2-MG,activated partial thromboplastin time(APTT),and prothrombin time activity(PTA)were more responsive to the severity of the patient's condition.KDIGO grade 2 and 3 had higher proportions of receiving transplants,diuretics,organ support(mechanical ventilation,application of vasoactive medications,and renal replacement therapy),and admissions to the intensive care unit(ICU),and with higher in-hospital mortality rates and 28-day mortality rates.Regression analysis found that creatinine,β2-MG,APTT,transplantation,and chemotherapy were independent risk factors for the development of AKI;the application of vasoactive drugs was both an independent risk factor for the development of AKI and for death at 28 days;and chemotherapy,length of hospitalization,and HGB and fibrinogen levels were protective factors for death at 28 days.Conclusion:AKI in EBV-HLH has high incidence and high rate of progression to severe disease and death,early attention should be given and strengthened in order to carry out early treatment and improve the prognosis of patients.
