Summary Background Problem of the variability between the different methods using for bone alkaline phosphatase (bALP) determination greately influences the clinical significance of bALP as direct marker of bone metabolism. The aim of this study was to compare immunoassay with electrophoresis technique for bALP determination. Methods We measured bALP in 71 patients on hemodialysis with agar gel electrophoresis (ISO-PAL, SEBIA) and immunoassay (OSTASE, Beckman Coulter). Results The analyzed methods showed significant correlation (Spearman’s rho: 0.776, P < 0.01), but we found statistically significant (P < 0.01) positive bias (27%) for the results measured by immunoassay. In support of this, using electrophoresis technique we have detected presence of the intestinal isoenzymes of alkaline phosphatase in 55% of patients with median value of 30% of the total alkaline phoshatase and presence of liver-2 alkaline phosphatase isoform in 42% of patients with median value of 16.6%. The Kendall’s W of 0.787 (P<0.0001) revealed significant concordance between two analysed methods. Cusum test showed no significant deviation from linearity (P=0.850). Conclusions Despite good agreement between immunoassay methods and electrophoresis technique for bALP determination, interchangeability between these two methods is questionable. Although immunoassays are increasingly used, as fully automated methods, in a large number of laboratories and become routine methods for bALP determination, it should be beared in mind, besides various interferences, also the heterogeneity of the bALP itself, especially in patients on hemodialysis.

AbstractFew cases of uraemic tumoral calcinosis (UTC) have been reported. This study aimed to investigate the clinical efficacy of parathyroidectomy for UTC. Historical clinical data of patients with end-stage renal disease and UTC who underwent parathyroidectomy were analysed. Absorption of metastatic calcification was compared before and after operation. Changes in intact parathyroid hormone, serum calcium, phosphorus, and alkaline phosphatase levels were analysed before parathyroidectomy and at 1 week and 3, 6, and 12 months after parathyroidectomy. Eight patients met the enrolment criteria (men, 6; mean age, 38.6 SD 10.9 years). Uraemic tumoral calcinosis, which developed 2–8 years after dialysis began, was caused by secondary hyperparathyroidism. Massive calcium deposition was found in the shoulder (n = 6), hip (n = 3), and elbow (n = 2). Four patients had > 2 joints affected, and a single joint was involved for four patients. Seven patients had rapid remission (< 6 months) of the masses after parathyroidectomy. In one patient, the mass remained unabsorbed until 6 months postoperatively. Hypocalcaemia occurred in all patients where parathyroidectomy was successful, and calcium supplementation was required 1 year postoperatively. Serum intact parathyroid hormone levels on day 7 and at 3 and 6 months postoperatively decreased significantly from baseline and remained low 1 year postoperatively (22.015 SD33.134 pg/mL). Postoperative phosphorus levels were significantly lower than preoperative levels (p < 0.05), but no significant difference was found in alkaline phosphatase levels (p > 0.05). Parathyroidectomy has promising efficacy for UTC treatment and regulation of serum intact parathyroid hormone and phosphorus. Hypocalcaemia is a common complication after parathyroidectomy.

Fifteen patients on regular dialytic treatment for more than 15 years were given X-rays of the skull, spine, shoulders, wrists, pelvis and knees with the purpose of studying the principal skeletal and articular alterations due or not due to the uraemic status. Serum calcium, phosphorus, parathyroid hormone, alkaline phosphatase and basal aluminium were recorded. Osteopenia was evident in all the patients. Ten of whom (67%) showed alterations due to hyperparathyroidism. Nine patients presented the marks of dialysis spondyloarthropathy; in 14/15 cases geodes were present in the wrists, humeral heads or hip-joints; in ten patients there were multiple amyloid lesions. Two patients with serum basal aluminum above 100 μg/L showed the typical radiographic marks of osteomalacia. The majority of the long-term survivors showed multifactorial osteo-articular alterations resulting mainly from the combination of hyperparathyroidism and dialysis-related amyloidosis. The less frequent joint alterations were represented by arthrosis, enthesopathy and Chondrocalcinosis. Disability and decreased articular mobility resulted in being mainly due to amyloid osteo-arthropathy.
