Clinical features of childhood hemophagocytic syndrome and its association with human parvovirus B19 infection
Objective To investigate the association of childhood hemophagocytic syndrome (HPS) with human parvovirus B19 (HPVB19) infection, and to analyze the clinical features of this disease. Methods ELISA and quantitative real-time PCR were used to detect HPVB19-IgM, HPVB19-IgG and HPVB19-DNA in 65 children with HPS (HPS group) and 65 healthy children (control group). The HPS group was divided into HPVB19-infected (n=14) and non-infected (n=51) groups according to the detection results of HPVB19-DNA. The clinical data of two groups were compared. Results The positive rate of HPVB19-IgM in the HPS group (26%, 17/65) was significantly higher than that in the control group (9%, 6/65) (P=0.011), and there was no significant difference in the positive rate of HPVB19-IgG between the HPS (38%, 25/65) and control groups (29%, 19/65) (P=0.266). The infection rate of HPVB19 in the HPS group (22%, 14/65) was significantly higher than that in the control group (3%, 2/65) (P=0.001). Compared with the noninfected group, the HPVB19-infected group had significantly lower platelet count and hemoglobin level on admission, significantly more severe liver function damage, a significantly earlier onset time, and a significantly longer course of disease (P<0.05). Conclusions The pathogenesis of HPS may be associated with HPVBl9 infection. HPVBl9-infected children with HPS have more acute onset, more severe clinical manifestations, and a longer disease duration.
