Influence of growth hormone (GH) receptor deletion of exon 3 and full-length isoforms on GH response and final height in patients with severe GH deficiency.

CONTEXT A polymorphism of the GH receptor (GHR) gene resulting in genomic deletion of exon 3 (GHR-d3) has been associated with responsiveness to GH therapy. However, the data reported so far do vary according to the underlying condition, replacement dose, and duration of the treatment. OBJECTIVE, DESIGN: The aim of this study was to analyze the impact of the GHR genotypes in terms of the initia...

Growth hormone (GH) assays: influence of standard preparations, GH isoforms, assay characteristics, and GH-binding protein.

The impact of the adoption of the new biosynthetic growth hormone (GH) WHO International Reference Preparation (IRP 88/624), and the recommendation to report results in microgram/L instead of mU/L, is described. Conversion factors were determined by comparing both the linear and nonlinear relations of the GH values. The Pharmacia polyclonal IRMA (p-IRMA) and the DELFIA monoclonal time-resolved ...

Growth hormone (GH) provocation tests and the response to GH treatment in GH deficiency.

OBJECTIVE To identify factors, particularly the growth hormone (GH) provocation test result, affecting growth response to GH treatment in children with GH deficiency (GHD). SUBJECTS A total of 337 prepubertal GHD patients aged <10 years from the UK Pharmacia KIGS database (GH response to provocation test <20 mU/l). OUTCOME MEASURE Annual change in height standard deviation score (SDS) (revi...

Comparison between the growth response to growth hormone (GH) therapy in children with partial GH insensitivity or mild GH deficiency.

OBJECTIVES GH therapy is still controversial, except in severe GH deficiency (SGHD). The objective of this study was to compare the response to growth hormone (GH) therapy in children with partial GH insensitivity (PGHIS) and mild GH deficiency (MGHD) with those with SGHD. SUBJECTS AND METHODS Fifteen PGHIS, 11 MGHD, and 19 SGHD subjects, followed up for more than one year in the Brazilian pu...

GH deficiency status combined with GH receptor polymorphism affects response to GH in children

Meta-analysis has shown a modest improvement in first-year growth response to recombinant human GH (r-hGH) for carriers of the exon 3-deleted GH receptor (GHRd3) polymorphism but with significant interstudy variability. The associations between GHRd3 and growth response to r-hGH over 3 years in relation to severity of GH deficiency (GHD) were investigated in patients from 14 countries. Treatmen...
