Abstract: After renal transplantation (Tx), children with growth retardation can be successfully treated with recombinant human growth hormone (rhGH). However, the impact of this treatment on kidney allograft function remains a source of concern. We report on one boy who received a cadaveric kidney transplant at 12 yr of age, after developing end-stage focal and segmental glomerulosclerosis and hyalinosis. The early post-transplant period was complicated by thrombosis of an arterial branch of the graft and two acute rejection episodes. Because of poor growth, the boy was treated with rhGH starting 22 months after the Tx. The renal function remained relatively stable for 22 months after initiation of rhGH therapy and then progressively deteriorated over a period of 10 months, with the patient ending up on dialysis. Several biopsies, performed for rejection episodes or before the start of rhGH, or to elucidate the deterioration of the renal function, were analyzed. Histologically, a progressive increase in the amount of hypertrophy of the tubules and of the glomeruli was seen after initiation of rhGH. Hyperplasia of the tubular epithelium with crowding of cells of the proximal tubules, hyperchromasia and irregularities in the shape of the nuclei, and abrupt changes of chromatism along the tubuli, were also observed. These lesions of tubular dysplasia are extremely unusual in transplanted kidneys and are unlikely to be caused by compensatory hypertrophy secondary to destruction of renal tissue. They may be an effect of rhGH treatment. The prognostic significance of these lesions is unknown but merits attention.
