[Hormonal, auxological and clinical follow-up in children with connatal HIV infection: personal records].
Auxological and endocrinological complications frequently occur in children with connatal HIV infection. These complications seem to be related both to the infection itself and the antiretroviral therapy. Many children consequently show height-weight and pubertal retardation without any evidence of hormonal deficit. We studied 10 children with connatal HIV infection who were enrolled in this analysis and followed up for 7 years in order to evaluate their height-weight growth, pubertal maturation, bone age progression and hormonal pattern [basal Growth hormone (GH) and GH after Clonidine or Insulin stimulation, Insulin-like Growth Factor 1 (IGF-1), Insulin-like Growth Factor Binding Protein 3 (IGFBP-3), FSH, LH, ACTH and Cortisol, TSH, fT4, T4, T3, Ab-TGO, Leptin]. Three children showed a height lower than 3rd centile during the first two years of their life and in prepubertal age, with recurring improvement in their growth rate. Weight growth was very compromised in one girl, remaining firmly lower than 3rd centile during the follow-up. Three children presented a weight lower than 3rd centile until they were two years old. However, a height growth rate higher than 10th centile was found in nine children throughout the follow-up, while it was pathological in five children. The blood level of Leptin was higher at the beginning of the study: 0.82 - 11.68 ng/l (M+/-DS: 3.29+/-4.15) than at its conclusion: 0.2 - 3 ng/l (M+/-DS: 1.65+/-1.01). There was a statistically significant correlation between leptinemia and the CD4/CD8 count (p: 0.010; r: 0.916) and the CDC classification (p: 0.006; r: 0.937), indicating a strong relationship with the degree of virological and immunological impairment. The authors stress the importance of a careful height-weight growth rate control in HIV-infected children, as it reflects the clinical and virological course of the disease. Adequate control of the infection allows physiological growth in most patients. Moreover, we emphasize the utility of IGFBP-3 and IGF-1 measurements, since they represent growth markers which are more exact and better capable of reproduction than GH.
