Childhood Kikuchi-Fujimoto disease

Abstract

To investigate the clinical features of Kikuchi-Fujimoto disease (KFD) and the relationship between viral infection and this disease in children will be better as Kikuchi-Fujimoto disease (KFD) is a lymphadenopathy. The aim of study is to investigate the clinical features of KFD and the relationship. The age, gender, clinical features and aetiopathogenesis of 36 Chinese children with FKD were reviewed, and the viral antigens were detected. Mean age was 10.1 ± 2.8 yr with a male to female ratio of 1.8:1. Fever and lymphadenopathy were the most common complaints, noted in 23 and all cases respectively. Skin rash and hepatosplenomegaly were also noted. Leukopenia, anemia, thrombocytopenia and raised ESR were noted in 21, 6, 4 and 31 cases respectively. Epstein-Barr virus (EBV) IgM and IgG was positive in 1 and 24 of 29 cases respectively. Antigens of EBV and herpes simplex virus 2 (HSV 2) were found in the biopsy tissue section from 2 and 1 case respectively. Autoantibodies were noted in 3 of 15 cases. Steroid hormones were administrated for 19 cases with good efficacy. These results imply that children with lymphadenopathy and/or fever may have KFD and thus excisional biopsy of lymph nodes should be performed earlier on. A hyperimmune reaction of immune cells to EBV and HSV2 may play a role in the pathology of KFD. © 2009 Dr. K C Chaudhuri Foundation.
