    Notes: Abstract. From 1991 to 1993, 90 children having received a kidney graft with a post-transplantation period of at least 12 months were included in a prospective study carried out in 18 French pediatric centers. After informed consent and randomization, children received recombinant human growth hormone (rhGH) (Genotonorm, Pharmacia peptide hormones) 30 U/m2 per week, either immediately on enrollment, for the treated group, or after 1 year of follow-up for the group serving as a control. After 1 year both groups were treated and we analyzed data during the subsequent years. Eighty-five children completed the 1-year study. Growth velocity was significantly increased by rhGH: 7.7 cm with a gain of +0.3 standard deviation score in the treated group versus 4.6 cm in the control group (P〈0.0001) during the 1st year. Four factors predicted response to therapy: growth velocity prior to GH therapy, glomerular filtration rate (GFR) at the start, mode of corticosteroid administration, and degree of insulin resistance. After 1 year we observed a moderate, significant decrease in GFR in both groups. Biopsy-proven acute rejection episodes were not significantly more frequent during the 1st year in the group of patients who received rhGH: 9 in 44 versus 4 in 46 patients. The patients who rejected did not differ in terms of age, renal function at the start, and type of immunosuppression, but history of rejection before GH treatment was discriminatory: 6 of 17 children with two or more episodes had a new rejection versus 1 of 22 who had no or only one episode (P=0.01). Glucose tolerance was not modified after 1 year of GH therapy. During the subsequent years of treatment a decrease in growth velocity was noted: 5.9 cm at 2 years, 5.5 at 3 years, and 5.2 cm at 4 years. In conclusion, GH is efficient for improving growth velocity in short transplanted children, inducing clear-cut but limited catch-up growth. The risk of rejection was shown only in patients with a prior history of more than one rejection episode.

    Pretransplant blood transfusions with cyclosporine in pediatric renal transplantation (2000)

    Notes: Abstract  Pretransplant transfusions were repeatedly shown to be associated with improved graft survival in the ”pre-cyclosporine era,” and have recently been shown to be beneficial in patients on modern immunosuppressive regimes. In an attempt to improve this transfusion effect and minimize the potential development of cytotoxic antibodies, we have given these transfusions, with concomitant cyclosporine cover, prior to transplantation. Ninety-two renal transplantations were performed in 91 children in the study group (group 1) and all received pretransplant transfusions with cyclosporine cover. Results were compared with a preceding group of 102 children (104 transplantations) who had received pretransplant transfusions without cyclosporine cover (group 2). There were 70 cadaver and 22 living-related donor (LRD) transplants in group 1, and 88 cadaver and 16 LRD transplants in group 2. Graft survival rates (1- and 5-year) for cadaver transplantation were 96% and 90% in group 1 compared with 78% and 64% in group 2 (P=0.001). For LRD transplantation, these figures were 95% and 87% in group 1 and 81% and 69% in group 2. There was no difference between the two groups in terms of age at transplantation, sex, donor age, HLA-A, -B, -DR mismatches, or cold and warm ischemia times. All cadaver graft recipients received quadruple, sequential immunosuppression post transplant. However, 9 patients in group 1 were changed to tacrolimus for recurrent rejection episodes. No patient developed persistent lymphocytotoxic antibodies post transfusion or side effects of cyclosporine. Cyclosporine can be safely given with whole blood prior to transplantation with no adverse effect and no sensitization. Graft survival was significantly improved in this group of patients and graft loss due to rejection was exceptional. This effect should be further evaluated in prospective studies.

    Growth after renal transplantation: Correlation with immunosuppressive therapy (1991)

    Notes: Abstract The growth data for children transplanted between 1973 and 1987 were analysed according to their immunosuppressive regimen. All patients treated before 1985 received conventional treatment (prednisone, azathioprine); 37% of the prepubertal children with a follow-up of longer than 2 years showed catch-up growth, and 30% of the pubertal children exhibited a normal adolescent growth spurt. Reduced renal function and corticosteroid treatment are the two main causes of growth delay. The children transplanted between January 1985 and September 1987 were given either triple therapy [cyclosporine (CsA), prednisone, azathioprine] or conventional treatment after randomisation. Growth data were significantly better with CsA. The mean height gain for prepubertal children was +0.24 SD/year on triple therapy and +0.14 SD/year on conventional therapy during the 1st year after transplantation; and 0.4 SD/year and 0 SD/year during the 2nd year (P〈0.05). The mean height gain for pubertal children was 5.6 cm/year on triple therapy and 3.6 cm/year on conventional therapy (P〈0.005). The patients on triple therapy also received a significantly lower cumulative dose of prednisone. Some selected patients on triple therapy were taken off prednisone 12 months after transplantation. All patients showed catch-up growth (+0.83 SD/year in prepubertal children, 7.2 cm/year in pubertal children). In conclusion, protocols including CsA and the lowest cumulative dose of steroid (with alternate-day or even steroid withdrawal) allow the best restoration of growth.

    Diabetes mellitus in patients with infantile cystinosis after renal transplantation (1999)

    Notes: Abstract  Diabetes mellitus is a frequent long-term complication of infantile nephropathic cystinosis. We studied 44 cystinotic patients, aged 22.1±5.4 years, transplanted at a mean age of 11.3±2.5 years; 25% were treated with insulin at 20 years of age or 10 years after transplantation, and over half required insulin at latest follow-up. In comparison, diabetes mellitus occurred in only 1% of non-cystinotic transplanted patients. Sequential oral glucose tolerance tests (OGTTs) in these patients showed the progressive deterioration of glucose metabolism. All but 2 patients had an abnormal response at latest follow-up. The high doses of corticosteroid given after transplantation or during rejection episodes were responsible for transient insulin dependency. However, the development of impaired glucose tolerance and diabetes mellitus depended mainly on the cystinotic process, which developed slowly with time. The deterioration of glucose tolerance was correlated with a decreased early phase of insulin secretion, estimated from the plasma insulin level at 30 min of the OGTT, while there was no evidence of insulin resistance. The occurrence of diabetes mellitus correlated with a worsening of the vital prognosis.
