The pre-treatment characteristics and evaluation of the effects of recombinant human growth hormone therapy in children with growth hormone deficiency and celiac disease or inflammatory bowel disease.

The Aim Of The Study: was to investigate the coincidence of growth hormone deficiency (GHD) and celiac disease (CD) or inflammatory bowel disease (IBD) in patients referred for short stature, and to evaluate the baseline anthropometric parameters and the effectiveness of recombinant human growth hormone (rhGH) therapy in the first year in those patients (GHD+CD/IBD subgroup) in comparison to patients with GHD without CD or IBD (GHD-CD/IBD subgroup).

Material And Methods: The study was retrospective and included 2196 short patients (height SDS [Standard Deviation Score] ≤ -1.2). 1454 patients had height SDS ≤ -2. Twenty-nine patients suffered from CD or IBD. GHD was confirmed in 419 patients with height SDS ≤ -2. The coexistence of GHD and CD or IBD was found in seven patients (GHD+CD/IBD subgroup).

Results: At baseline the GHD-CD/IBD subgroup did not differ significantly in chronological age, height SDS, height velocity (HV) before rhGH therapy, body weight SDS, and body mass index SDS from the GHD+CD/IBD subgroup. The improvement in height SDS within the first year of rhGH therapy was higher in the GHD+CD/IBD subgroup than in the GHD-CD/IBD subgroup and the difference was statistically significant (p<0.05). HV in the first year of rhGH therapy was also significantly higher in the GHD+CD/IBD subgroup than in the GHD-CD/IBD subgroup (p < 0.05).

Conclusions: In patients with chronic inflammatory disorders of the gastrointestinal tract, especially celiac disease, coexisting with GHD, rhGH therapy could be effective and should be administered together with therapy of primary gastrointestinal disease.
