The density of bone in the distal third of the radius is measured by I-125 photon absorptiometry in 38 RDT (Regular Dialysis Treatment) patients (19 mean and 19 women, age range from 17 to 65 years). In the majority of patients the bone density (BMC/W) is reduced. The clinical follow-up of dialysis patients demonstrates that the incidence and severity of clinical symtpoms do not always correlate closely with the bone density values, nor with the biochemistry and histopathological findings of bone disease associated with dialysis. Despite control of calcium and phosphorus metabolism, decreased mineralization of the appendicular skeleton persists. The advantages as well as disadvantages of bone density measurements in RDT patients are discussed.

Careful investigation of the clinical conditions of patients on maintenance hemodialysis for about 20 years in a single dialysis unit was of great interest for evaluation of the pathological consequences in long-term survivors of insufficient correction of uremia and of the dialysis treatment "per se". We analyzed the outcomes for a cohort of 116 patients who started RDT before 1976 and the clinical conditions of the 24 patients still on RDT in our unit at the end of 1991 (average duration of treatment = 222 +/- 23 months). Actuarial survival was 72% at 10 years and 43% at 20 years. Rehabilitation of the 24 survivors was rather good: 13 were able to work, 8 were retired or unable to work, but able to care for most personal needs. Actual body weight, anthropometric parameters and biochemical parameters revealed a well-preserved nutritional status. Anemia improved from 23 +/- 7 at the start of RDT to 31 +/- 8 in the 21 patients never treated with erythropoietin. Blood pressure was normal without therapy in 18 patients and elevated in 6. Mild-to-moderate left ventricular hypertrophy was present in all the 6 patients with arterial hypertension and in only 6 of the 18 normotensive patients. The ratio of early diastolic filling to filling during atrial contraction (E/A ratio) was < 1 in 16 patients: it was 1.05 +/- 0.43 in 9 patients with stable intradialysis blood pressure and significantly lower (0.73 +/- 0.15) in 12 patients with recurrent intradialysis hypotension. Supraventricular arrhythmias were detected by Holter monitoring in 41% and ventricular arrhythmias in 35% of patients. Extensive vascular calcifications were present (in 100% of patients in the abdominal aorta), but only 4 patients showed clinical signs of peripheral vascular disease. Subperiosteal resorption was detected radiologically in the hands of 59% of patients. Bone histology, interpretable for only 20 patients, revealed no bone lesions in 1 case (5%), mild mixed osteodystrophy in 3 cases (15%), advanced mixed osteodystrophy in 5 cases (25%), osteodystrophy with predominant hyperparathyroidism in 2 cases (10%), osteodystrophy with predominant osteomalacia in 6 cases (30%), and aplastic bone disease in 3 cases (15%). Moderate aluminum staining was found in only 4 patients and was more marked in earlier biopsies taken before withdrawal of the aluminium-containing phosphate-binding drugs.(ABSTRACT TRUNCATED AT 400 WORDS)
