CD64 expression on monocytes in children with adenoid hypertrophy.

OBJECTIVE Adenoids with obstructive hypertrophy (AH) are considered to be one of the most ancient and common problems in Paediatrics. This study aimed at investigating the expression of CD 64 on monocytes in children who had to undergo adenoidectomy. METHODS Therefore, 66 children (24 females, 42 males, mean age 4.9 years), affected by AH and requiring adenoidectomy (54%) or adeno-tonsillectomy (46%) were consecutively enrolled into the study. Moreover, 30 healthy children (11 females, 19 males, mean age 11.2 years) were enrolled in this study as controls. CD64 expression on monocytes was measured. RESULTS Children with severe AH had higher CD64 values than children with AH size 3 and controls. CONCLUSIONS This preliminary study shows that CD64 expression on monocytes may be associated with severe AH, suggesting a more intense immune activation in these subjects.
