A 4-year-old girl, who had been in perfect health, presented with the acute onset of renal failure and abdominal mass. Investigations revealed a solitary left kidney which on histology had the typical features of xanthogranulomatous pyelonephritis. The child had no previous history suggestive of chronic renal disease and had no radiologic evidence of renal osteodystrophy. She had no improvement in renal function and has gone on to hemodialysis and transplantation. The unique mode of presentation and the unusual features of this case are discussed.

Histomorphometry was performed on transiliac bone biopsies, double-labeled with tetracycline, from 60 consecutively admitted patients (20 women) at various stages of chronic renal failure (CRF). Eleven patients (1 woman) had normal bone resorption and formation indices. Bone resorption and osteoid formation increased with progression of renal failure, but abnormal values were seen even at slightly elevated creatinine levels. Mineralization lag time increased with CRF duration; prolonged values were only seen in patients with polycystic kidney disease or chronic pyelonephritis with advanced CRF. All patients with impaired mineralization also had increased bone resorption. Diabetes mellitus did not protect against skeletal lesions. The biochemical tests were too insensitive to predict type or severity of bone disease, and hand X-rays had no diagnostic value in early stages of renal osteodystrophy.

Bone morphological parameters of renal osteodystrophy such as abundance of osteoid surface, osteoid seam width index, calcification fronts, osteoclast activity and trabecular bone volume were studied in 71 patients on maintenance hemodialysis and compared with bone densitometry, laboratory and clinical data. Increased osteoclast activity (hyperparathyroidism) was by far the most common bone morphological finding. Patients with chronic pyelonephritis or polycystic kidney disease had more than double the amount of osteoid than patients with chronic glomerulonephritis. The trabecular bone volume seemed to be increased in most patients in contrast to the cortical bone volume which was decreased, judged from bone densitometry and previously from X-ray. Despite that patients with polycystic kidney disease were older, their trabecular volume was larger than in patients with glomerulonephritis. The bone mineral content evaluated by bone densitometry was low in most patients, and more associated with bone morphological signs of osteomalacia than with secondary hyperparathyroidism. Serum phosphate (S-PO4) and serum parathyroid hormone (S-PTH) seemed to discriminate better between osteomalacia and secondary hyperparathyroidism than serum alkaline phosphatase (S-Alk. phosph.), which was elevated in both groups. Patients who had been bilaterally nephrectomized were no more abnormal than other patients, and they had lower S-Alk. phosph. The abundance of osteoclasts was found to be a predictor of future development of clinical secondary hyperparathyroidism.

A woman with chronic pyelonephritis developed progressive muscular weakness and bone pain. For twenty years she had habitually ingested fluoride-rich soil. Osteosclerosis was found on x-ray examination, and fluorosis was confirmed by bone biopsy. Renal failure augmented skeletal retention of excessive fluoride intake which, in turn, appears to have intensified symptomatic renal osteodystrophy. Skeletal fluorosis from this unexpected source has not been previously described.

Between 1996 and 1997, 86 patients were treated for terminal renal failure by hemodialysis at Maribor Teaching Hospital. Among them were 12 with iPTH over 900 pg/ml and symptoms of bone disease. In these patients bone biopsy was carried out with the aim of determining the type of renal osteodystrophy (RO) and establishing a possible correlation with the clinical picture, with densitometry and laboratory results. Histomorphologically, 6 patients fulfilled the criteria for secondary hyperparathyroidism (HT) - 3 with analgetic nephropathy (AN), one with chronic pyelonephritis (CPN), one with vascular nephropathy (VN), one with chronic glomerulonephritis (CGN). Six patients fulfilled the criteria for mixed osteodystrophy (MO) - 3 AN, 2 CGN, one VN. According to laboratory findings and bone mineral density (BMD), a statistically significant difference between HT and MO was present only in AP (Table 1). The most frequent diagnosis in patients with iPTH >900 pg/ml was analgetic nephropathy.
