Clinical, pathologic, and immunologic features of human T-lymphotropic virus type I- associated infective dermatitis in children

ABSTRACT

Objectives: To define the clinical and laboratory features associated with infective dermatitis (ID) and confirm its association with human T-lymphotropic virus type 1 (HTLV-I). Design: A case series of patients with ID were compared with patients with atopic dermatitis (AD) which is an important disease in the differential diagnosis of ID. Setting: Patients were recruited from dermatology and pediatric clinics at the University Hospital of the West Indies and the Bustamante Children's Hospital, Kingston, Jamaica. Main Outcome Measures: Clinical and laboratory features of patients with AD were compared with those of patients with ID. Patients Consecutive patients older than 1« years diagnosed as having ID (n=50) and AD (n=35) were enrolled based on clinical findings. Results: The mean age of patients with ID and AD were 6.9 and 7.8 years, respectively. Histologically, both disease were predominantly chronic dermatitis... Conclusion: Infective dermatitis is a distinct clinical entity associated with HTLV-I, which plays a role in the pathogenesis and immune perturbations observed.(AU)
