Abstract

This study aims to evaluate the risk factors and prognosis for CMV diseases in hematologic malignancy patients without hematopoietic stem-cell transplantation (HSCT). We performed a case-control study (1:2) between 2012 and 2022. Adults with pathologic-confirmed CMV diseases (n=60) among hematologic malignancy patients were matched and compared to whom without CMV disease. Lymphoma was the most common underlying malignancy, and gastrointestinal tract involvement was the most common CMV disease. In the case group, high-dose steroid administration and transfusion within one month before diagnosis were higher (p<0.001). Steroid administration (aOR=5.78; 95% confidence interval: 1.25-26.68, p=0.024), red blood cell transfusion within one month (aOR=14.63; 2.75-77.76, p=0.002), low BMI (aOR=13.46, 2.07-87.45, p=0.006), and hypoalbuminemia (aOR=26.48, 5.93-118.17, p<0.001) were independent risk factors associated with CMV disease. The 30-day mortality was higher in the case group and CMV disease was significantly associated with all-cause mortality (aOR=14.41, 3.23-64.31, p<0.001). In hematologic malignancy patients without HSCT, risk factors for CMV organ disease included high-dose steroid administration and RBC transfusion within one month, low BMI, and hypoalbuminemia. Overall mortality was significantly higher with CMV disease, and CMV disease occurrence was a significant risk factor for mortality.
