Selected AbstractsA Randomized Trial to Assess the Impact of Early Steroid Withdrawal on Growth in Pediatric Renal Transplantation: The TWIST StudyAMERICAN JOURNAL OF TRANSPLANTATION, Issue 4 2010R. Grenda Minimizing steroid exposure in pediatric renal transplant recipients can improve linear growth and reduce metabolic disorders. This randomized multicenter study investigated the impact of early steroid withdrawal on mean change in height standard deviation score (SDS) and the safety and efficacy of two immunosuppressive regimens during the first 6 months after transplantation. Children received tacrolimus, MMF, two doses of daclizumab and steroids until day 4 (TAC/MMF/DAC, n=98) or tacrolimus, MMF and standard-dose steroids (TAC/MMF/STR, n=98). Mean change in height SDS was 0.16 ± 0.32 with TAC/MMF/DAC and 0.03 ± 0.32 with TAC/MMF/STR. The mean treatment group difference was 0.13 (p < 0.005 [95% CI 0.04,0.22]), 0.21 in prepubertal (p = 0.009 [95% CI 0.05,0.36]) and 0.05 in pubertal children (p = ns). Frequency of biopsy-proven acute rejection was 10.2%, TAC/MMF/DAC, and 7.1%, TAC/MMF/STR. Patient and graft survival and renal function were similar. Significantly greater reductions in total cholesterol and triglycerides but significantly higher incidences of infection and anemia were found with TAC/MMF/DAC (p < 0.05 all comparisons). Early steroid withdrawal significantly aided growth at 6 months more so in prepubertal than pubertal children. This was accompanied by significantly better lipid and glucose metabolism profiles without increases in graft rejection or loss.

Adiponectin is a strong determinant of insulin sensitivity. Objective, The aim of this study was to evaluate insulin resistance and adiponectin levels in SGA born children with catch-up growth (CUG) in the absence of obesity in prepubertal ages and relations with body composition and insulin-like growth factor binding protein (IGFBP)-1. Methods, Twenty-four (15F, 9M) SGA born children with CUG but without obesity were evaluated at age 6·3 ± 0·5 years with respect to glucose, insulin, IGFBP-1, leptin and adiponectin levels, and body composition by dual-energy X-ray absorptiometry (DEXA). Their data were compared to that of 62 (27F, 35M) appropriate for gestational age (AGA) children. Results, SGA and AGA children had similar height standard deviation score (SDS) corrected for parental height and body mass index (BMI) SDS. Homeostasis model for insulin resistance (HOMA-IR) was significantly high in SGA (0·7 ± 0·6) than in AGA children (0·4 ± 0·2) (P = 0·029). There were no significant differences in leptin, IGFBP-1, adiponectin, and total and truncal fat between SGA and AGA children. However, being born SGA and having higher BMI in the upper half for the distribution in the sample, although within normal ranges, was associated with lower adiponectin levels (estimated means of log adiponectin levels 3·8 ± 0·3 vs. 4·4 ± 0·1 µg/ml, P = 0·040). Conclusions, SGA children with CUG and with no obesity have higher insulin levels compared to AGA children. Both SGA birth and recent size seem to have an effect on serum adiponectin levels in childhood.

The aim of the study was to evaluate insulin sensitivity (IS) and glucose tolerance (GT) in a group of GH-deficient children treated with GH for a period of 6 years. patients and design, One hundred and twenty-eight children (40 females, 88 males) were included in the study. At the beginning of treatment chronological age was 8·9 ± 3·2 years, height standard deviation score (SDS) ,2·43 ± 0·90 and body mass index (BMI) SDS 0·18 ± 1·60. At the end of the study chronological age was 13·0 ± 2·9 years, height SDS ,1·24 ± 1·27 and BMI SDS 0·23 ± 1·54. GH was administered at a mean weekly dosage of 0·3 mg/kg, injected subcutaneously over 6,7 days. GT was assessed according to the criteria of the Expert Committee on the Diagnosis and Classification of Diabetes Mellitus. IS was evaluated with the quantitative insulin sensitivity check index (QUICKI). results, No cases of impaired GT or diabetes were recorded during the follow-up period. IS, already lower than in controls before starting treatment with GH, decreased significantly during the first year of therapy (QUICKI: 0·346 ± 0·033 vs. 0·355 ± 0·044, P < 0·05), with no further decrease in the following years. No correlation was found between QUICKI, BMI, years of treatment and onset of puberty. conclusions, GH treatment in GH-deficient children does not lead to an impaired GT or type 2 diabetes mellitus, although it does significantly decrease IS. [source] Confirmation of severe GH deficiency after final height in patients diagnosed as GH deficient during childhoodCLINICAL ENDOCRINOLOGY, Issue 4 2002Andrea F. Attanasio Summary objective Human GH treatment of patients with childhood-onset (CO) growth hormone deficiency (GHD) ceases when they reach final height; this provides an opportunity to retest GH status in all patients before determining whether GH therapy will be required in adult life. At present, the diagnostic approach to these patients is not fully standardized. This study aimed to characterize a large group of previously GH-treated CO GHD patients and establish their GH status. patients and methods The multinational study included 167 patients diagnosed as GH deficient and treated with hGH to final height during childhood. Mean age was 19·2 years and mean height standard deviation score (SDS) was ,1·08. Peak serum GH concentrations were determined in standard GH stimulation tests. IGF-I and IGFBP-3 concentrations were determined at a central laboratory and converted to SDS values by reference to a normal population. results Using only a peak GH value of less than 3 µg/l (1 mg = 3 U) in stimulation tests as the cut-off, 133 (79·6%) patients would be classed as GH deficient. Using only an IGF-I value less than ,2 SDS as the cut-off, 134 (80·2%) patients would be classed as GH deficient. However, by using both criteria there were 120 (71·9%) patients who were definitely severely GH deficient (group 1) and 20 (12·0%) who were not GH deficient (group 2), leaving 14 (8·4%) classed as GH deficient from IGF-I SDS only (group 3) and 13 (7·8%) classed as GH deficient from stimulation test only (group 4). There was no difference between the groups in height SDS or body mass index (BMI), but the GH-deficient patients tended to have been diagnosed at a younger age (group 1, 8·2 ± 3·9; group 2, 10·0 ± 4·0; P = 0·052). For patients classed as GH deficient compared with those not GH deficient, the percentage of males was lower (group 1, 64·2%; group 2, 90·0%; P = 0·022) and the percentage with multiple pituitary hormone deficiencies was higher (group 1, 81·7%; group 2, 20·0%; P < 0·001), with the other two groups being intermediate in each case. Only the group classed as GH deficient by both criteria had a mean IGFBP-3 less than ,2 SDS and both IGF-I SDS and IGFBP-3 SDS increased steadily across the four groups. conclusions A high percentage (71·9%) of these childhood-onset GH-deficient patients were still GH deficient in adult life and are likely to require further hGH treatment. While 12·0% could be classed as definitely no longer GH deficient, there are some patients who are intermediate (16·2%) and may be classed as GH deficient by one criterion but not the other. When GH stimulation test results and IGF-I concentration are discordant, the IGFBP-3 level does not establish diagnosis and the hGH treatment requirement of such patients remains a dilemma. [source] Effect of a gluten-free diet on growth and small-bowel histology in children with celiac disease in IndiaJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 8 2007Surender K Yachha Abstract Background and Aim:, Follow-up studies on growth and histological recovery of children with celiac disease (CD) while on a gluten-free diet (GFD) are lacking from Asia. We therefore assessed the effects of this diet. Methods:, Forty-two children with CD were enrolled. Weight and height were expressed as weight for height (WfH) and height standard deviation scores (HSDS), respectively. Twenty-five children had repeated duodenal biopsies after 1,2 years and 14 had a third biopsy after 3,7 years of GFD. Compliance was checked by regular interview and IgA antiendomysial antibody estimation (EMA). Results:, At diagnosis (n = 25), mean HSDS was ,3.3 ± 1.6 with 76% having a HSDS of <,2; 60% were undernourished (WfH mean 81.6 ± 5.7). Over a mean follow up of 3.7 years, HSDS improved to ,1.3 ± 1.7 and 84% cases achieved normal nutrition. Mean height velocity was 13.9 cm during first year and 5.6 cm in subsequent years. Small-bowel biopsies at diagnosis showed subtotal villous atrophy (Marsh IIIb) in 18 (72%) and partial villous atrophy (Marsh IIIa) in seven (28%) patients. Repeat biopsy at 1,2 years showed shift from subtotal to partial villous atrophy in 94% (n = 17/18) and normalization in one patient. In patients with Marsh IIIa improvement of partial villous atrophy was observed in all. Immunoglobulin A endomysial antibody was negative in 81%. Repeat biopsies at 5 years of GFD showed improvement to Marsh I,II, but none normalized. Conclusion:, The majority of children with CD show normalization of nutrition and growth after GFD. Small-bowel histology improves markedly but does not normalize even after 5 years of GFD. [source] |
