Growth, chronic kidney disease and pediatric kidney transplantation: is it useful to use recombinant growth hormone in Colombian children with renal transplant?

Kidney transplantation has become the best treatment for children with chronic kidney disease (CKD). In recent times, knowledge concerning the effect of CKD and kidney transplantation over the normal growth rate has increased; now it is known that 40% of children with CKD do not reach the expected height for age. Growth retardation has been associated with the type of nephropathy, metabolic and endocrine disorders that are secondary to kidney disease, immunosuppressive therapy with glucocorticoids, and suboptimal function of renal allograft. Nowadays, we know better the role of the growth hormone/insulin-like growth factor 1 axis in growth retardation we can see it in children with CKD or recipients of renal allograft. Several studies have shown that administration of recombinant growth hormone (rhGH) has a positive effect on the longitudinal growth of children and teenagers who have received a kidney transplant. On the other hand, there have been reported side effects associated with using rhGH; however, these are not statistically significant. In this article, we show a small review about growth in children with CKD and/or recipients of renal allografts the growth pattern of three children who were known by the Transplant Group of National University of Colombia, and the results obtained with the use of rhGH in one of these cases. We want to show the possibility of achieving a secure use of rhGH in children with CKD and its use as a therapeutic option for treating the growth retardation in children with kidney transplantation, and set out the need of typifying the growth pattern of Colombian children with CKD and/or who are recipients of renal allografts through multicenter studies to propose and analyze the inclusion of rhGH in the therapeutic scheme of Colombian children with these two medical conditions. rhGH could be a useful tool for treating children with CKD or kidney transplantation who have not reached the expected longitudinal growth for age. However, it is necessary to know the growth pattern standards for Colombian children with CKD or kidney transplant in Bogotá-Colombia to include the rhGH in clinical protocols for treatment of these patients.
