Aims:Growth hormone deficiency therapy is demanding for patients and caregivers. Teams engaged in the clinical management of growth hormone deficiency therapy need to know how families live with this condition, to provide an adequate support and prevent the risk of withdrawal from therapy.Methods:Using Narrative Medicine, testimonies from patients, their parents and providers of care were collected from 11 Italian centers. Narrations were analyzed throughout an elaboration of recurring words and expressions.Results:Although care management and outcomes were considered satisfying in the 182 collected narratives, recurring signals of intolerance among adolescents and the worry of not being well informed about side effects among parents are open issues.Conclusion:Narratives found that communication issues could decrease adherence and influence the physicians’ clinical practice.
Peripheral GH insensitivity may underlie idiopathic short stature in children. As the clinical and biochemical hallmarks of partial GH insensitivity have not yet been clearly elucidated, the identification of such patients is still difficult. We integrated functional, biochemical, and molecular studies to define the more reliable marker(s) of GH insensitivity. In particular, we measured GH receptor transducing properties through GH-induced protein tyrosine phosphorylation in patients' peripheral blood mononuclear cells and performed direct sequencing analysis of GH receptor-coding exons. Five of 14 idiopathic short stature patients with low basal IGF-I levels showed low or absent IGF-I increment after 4 d of GH administration. However, a prolonged GH stimulation induced in 3 of them an increase in IGF-I 40% above the baseline value. The IGF-binding protein-3 behavior paralleled that of IGF-I. The 2 GH-unresponsive subjects showed an abnormal tyrosine phosphorylation pattern after GH challenge. Sequence analysis of the GH receptor gene revealed a heterozygous mutation resulting in an Arg to Cys change (R161C) in exon 6 in only 1 patient, who had normal GH receptor responsiveness. Our findings indicate that abnormal GH receptor signaling may underlie idiopathic short stature even in the absence of GH receptor mutations. Thus, combining the 4-d IGF-I generation test and the analysis of GH-induced protein tyrosine phosphorylation is a useful tool to help identify idiopathic short stature patients with partial GH insensitivity.
The impact of treatment of central precocious puberty (CPP) with gonadotropin-releasing hormone agonists (GnRHa) on final height remains controversial. We analyzed the long term results of 23 girls with CPP treated with triptorelin or leuprolide. Their "near final height" (NFH) assessed at a bone age of at least 14 years and expressed as SDS, was compared either with predicted height before treatment (PAH) or with parental height (TH). We also compared NFH of 12 girls treated before 8 years of age (7.0 +/- 0.5 yr) with NFH of 11 girls treated after 8 years old (8.5 +/- 0.3 yr). The NFH of the 23 girls (-0.9 +/- 1.0 SDS) was not different either from PAH (-0.85 +/- 1.5 SDS) or from TH (-0.5 +/0.6 SDS). Earlier treated girls reached a NFH (-0.97 +/- 1.0 SDS) not different from later treated girls (-0.91 +/- 1.0 SDS; p = ns) and both groups reached parental height (NFH - TH = -0.44 +/- 1 and -0.09 +/- 0.83 SDS, respectively). In conclusion, our patients, treated either earlier or later, reached a near final height comparable to predicted height and familial target; however, these results might still improve further because the girls have not yet reached their final adult height.
Psychosocial issues are part of the well-being of children with HIV. The ICF is a standard tool to evaluate the clinical and psychosocial status of children and adolescents with HIV infection and to measure the impact of therapeutic interventions and strategies on psychosocial functioning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
