Growth impairment, IGF I hyposecretion and thyroid dysfunction in children with perinatal HIV-1 infection.
We evaluated the growth pattern, bone age, insulin-like growth factor I (IGF I) secretion and thyroid function in 24 perinatally infected children: 9 asymptomatic or paucisymptomatic (group 1) and 15 with a more advanced disease state and treated with zidovudine (group 2). Statural and ponderal growth were compared with those of 37 at-risk children who seroreverted. During the two-year follow-up, 22% of children in group 1 had impaired growth, 33% bone age delay, 45% reduced IGF I levels but none had thyroid dysfunction. In group 2, 53% had growth failure, 53% bone age delay, 86% reduced IGF I levels and 40% thyroid dysfunction. Among seroreverters, none showed growth impairment; statistically significant differences were found for height, weight and height velocity between perinatally infected children and seroreverters. Since auxological and hormonal evaluations run parallel to the clinical course of infection, these indices may be useful in monitoring disease progression.
