Résumé
PURPOSE: Patients with malignant hematologic disorders undergoing bone marrow transplantation (BMT) may develop renal insufficiency. A study was undertaken to assess prospectively the subclinical renal function changes with radioisotopic methods in patients undergoing BMT for hematologic malignancies. METHODS AND MATERIALS: We studied 71 patients with normal renal function undergoing BMT for various hematologic malignancies, mostly leukemias. Conditioning included chemotherapy and 12 Gy (45 patients) or 13.5 Gy (26 patients) fractionated total-body irradiation (TBI). In 21 patients receiving 12 Gy TBI, the kidney dose was limited to 10 Gy using partial transmission blocks fabricated after renal opacification with nonionic, hypo-osmolar contrast medium. The glomerular filtration rate (GFR) and effective renal plasmatic flow (ERPF) were determined radioisotopically before conditioning and at 4, 12, and 18 months, using (51)Cr ethylene-diamine-tetra-acetic acid and (131)I ortho-iodo-hippurate, respectively. Renal insufficiency was defined as a decrease of >/=30% in GFR or ERPF compared with the baseline values. The potential influence of patient- and treatment-related variables on renal dysfunction was assessed. RESULTS: At 4 (early) and 12-18 (late) months, a >/=30% GFR drop was observed in 54% and 49% of patients and a >/=30% ERPF drop in 44% and 34% of patients, respectively. After stepwise logistic analysis, a GFR reduction at 4 months correlated significantly with age (<40 years old, worse), TBI using kidney blocks (partial kidney shielding to 10 Gy was associated with a higher rate of renal dysfunction at 4 months compared with the full TBI dose), and days of aminoglycoside/vancomycin use. An ERPF drop at 4 months was independently related with the days of amphotericin use and days of prostaglandin E(1) use (prophylaxis against hepatic venoocclusive disease). A GFR and ERPF reduction at 12-18 months correlated with days of amphotericin use and days of prostaglandin E(1) use, respectively. CONCLUSION: Early post-BMT renal dysfunction is associated with the administration of potentially nephrotoxic drugs. An inverse correlation with the prescribed TBI dose was observed; patients whose kidneys received 10 Gy through the use of partial shielding blocks had significantly greater renal dysfunction at 4 months. The administration of potentially nephrotoxic contrast agents used in radiotherapy treatment planning may be responsible for the latter observation. Prostaglandin E(1) use correlated with a significant reduction in ERPF at both 4 and 12-18 months.
