  • Title: Persistence of diminished bone mineral content following renal transplantation in childhood.
    Author: Chesney RW, Rose PG, Mazess RB.
    Journal: Pediatrics; 1984 Apr; 73(4):459-66. PubMed ID: 6369239.
    Abstract:
    Bone mineral content (BMC) was measured in the nondominant arm of 18 children (aged 3 7/12 to 17 1/2 years) for a total 783 months after renal transplantation. Using photon absorptiometry, 89 measurements were made; 17 of the 18 patients had a functioning graft and one patient died. Significant demineralization, a BMC greater than -2 SD below appropriate control volumes, was found in 11 of 18 patients (62%) and 55 of 89 measurements (61%). Bone loss was progressive; among the 16 patients followed for more than 6 months, ten showed a decline of more than 0.5 SD in BMC, five had no change, and only one showed improvement. No relationship was found between BMC and the use of furosemide, type of transplant (15 living, seven cadaver), prior renal disease (six with glomerulonephritis, 11 tubulointerstitial), need for a second graft (five patients), chronic anticonvulsant therapy, or serum calcium and phosphate values. BMC was slightly correlated (P less than .05) with alkaline phosphatase values. BMC was more strongly correlated with serum creatinine (y = -0.48x + 1.25, r = -.042, P less than .001) and prednisone dose (mg/kg/d) (y = -0.65x + 0.481, r = -.543, P less than .001) in an inverse relationship. Patients whose serum creatinine value was less than 1 mg/dL had a BMC of -0.71 +/- 0.34 SD; those with serum creatinine value greater than 2 mg/dL had BMC of -3.32 +/- 0.31 SD, different at P less than .001. Patients receiving daily prednisone therapy had a significantly lower BMC than those receiving alternate-day therapy (-3.11 +/- 1.23 SD v -1.72 +/- 1.29 SD, P less than .005).(ABSTRACT TRUNCATED AT 250 WORDS)
