Hyperphosphatemia, hypocalcemia and vitamin D deficiency are the main factors involved in the pathogenesis of secondary hyperparathyroidism (SHPT). Moreover, the skeletal resistance to parathyroid hormone is not only a high-turnover bone accompanying SHPT, but may also play a crucial role in the onset of low-turnover bone disease in uremia. However, a growing body of evidence suggests that other hormones play a key role in this disease, such as fibroblast growth factor 23, Klotho and sclerostin. SHPT causes both bone-associated and non-skeletal consequences, including cardiovascular calcifications. Furthermore, vitamin D and calcium (Ca)-containing phosphate binders may increase Ca load. Anyway, the rate of parathyroidectomy in end-stage renal disease has greatly decreased during the last decade. Is there any room left for surgeons?

Abstract Background The kidney plays a vital role in the metabolism of minerals and bone health. It is not only the target organ of several regulating hormones such as parathormon (PTH) and fibroblast growth factor-23 (FGF-23), but it is also the main organ that activates vitamin D. Calcium and phosphorus are fundamentally important in a wide array of biological functions. Abnormalities in calcium, phosphorus, parathyroid hormone (PTH), and vitamin D metabolism (usually referred to as disordered mineral metabolism) are common in patients with (CKD). Aim of the work Comparing the effect of hemodiafiltration (HDF) versus conventional Hemodialysis on bone markers. Patients and Methods The study was performed on 50 patients in Ain Shams University Specialized Hospital with end-stage renal failure treated by means of chronic hemodialysis (n = 25) and hemodiafiltration (n = 25). Inclusion criteria were end stage renal disease patients on regular hemodialysis for > 6 months, their age> 18 years old, no recent infection (normal CRP), cardiac or vascular access complication, none of the patients had history of bone disease, fracture or malignancy. As regarding blood transfusion and drug intake (affect bone metabolism or hemostasis) had not administered for 1 month perior to study. Results Both groups had lower levels of serum creatinine before and after sessions of HD or HDF but Hemodialysis (HD) patients has higher levels of phosphate and bone ALP, than patients on HDF. Conclusion Hemodiafiltration (HDF) has better effect on bone metabolism than Hemodialysis (HD).

AbstractPatients with end-stage renal disease (ESRD) may demonstrate secondary hyperparathyroidism (SHPT), characterized by parathyroid hormone oversecretion in response to electrolyte imbalance (e.g., hypocalcemia and hyperphosphatemia). Moreover, this electrolyte imbalance may affect vocal cord muscle contraction and lead to voice change. Here, we explored the effects of SHPT on the voices of patients with ESRD. We used data of 147,026 patients with ESRD from the registry for catastrophic illness patients, a sub-database of Taiwan National Health Insurance Research Database. We divided these patients into 2 groups based on whether they had hyperparathyroidism (HPT) and compared vocal dysfunction (VD) incidence among them. We also prospectively included 60 ESRD patients with SHPT; 45 of them underwent parathyroidectomy. Preoperatively and postoperatively, voice analysis was used to investigate changes in vocal parameters. In the real-world database analysis, the presence of HPT significantly increased VD incidence in patients with ESRD (p = 0.003): Cox regression analysis results indicated that patients with ESRD had an approximately 1.6-fold increased VD risk (p = 0.003). In the clinical analysis, the “jitter” and “shimmer” factors improved significantly after operation, whereas the aerodynamic factors remained unchanged. In conclusion, SHPT was an independent risk factor for VD in patients with ESRD, mainly affecting their acoustic factors.

Background/Aim. The disturbances of active forms of vitamin D synthesis and disturbances in calcium and posphate metabolism develop early in chronic renal failure, when creatinine clearance is about 30 ml/min. Chronic hemodialysis and peritoneal dialysis only partially correct the biochemical environment of patients on chronic renal replacement therapy because of end-stage renal disease. These dialysis modalities can?t significantly affect the endocrine disturbances of chronic renal failure and they have minimal modulatory effect. The management of disturbed calcium (Ca) and phosphate (P) metabolism and the maintainance of Ca ? P product below 4.4 mmol/l thanks to the use of dialysate solutions with the appropriate calcium concentration and the careful dosage of phosphate binders, calcium and active vitamin D metabolits, are extremely important for the prevention of renal osteodystrophy, secondary hyperparathyroidism as well as low-bone turnover disease. The aim of the study was to analyze the plasma levels of calcium, phosphate, albumin, alkaline phosphatase and parathormon (PTH) in 58 patients who were treated with continuous ambulatory peritoneal dialysis (CAPD) from March to August 2003. The use of phosphate binders and the substitution with active vitamin D metabolits were also analyzed. Methods. We examined 58 patients, 30 males and 28 female, mean-age 52 years (range, 26-78 years), affected by end-stage renal disease of the different leading cause. The average time on peritoneal dialysis program was 20 months (2-66 months). Most of the patients were treated by CAPD, while only few of them performed automatic, cyclic or intermittent peritoneal dialysis. Most of the patients used a dialysate with 1.75 mmol/l calcium concentration. Results. The study showed that our patients on chronic CAPD program during several months had normal calcemia, phosphatemia and the level of alkaline phosphatase, and that they had Ca ? P product in the recommended range. PTH serum level ranged from 16 to 490 pg/l in our patients. Conclusion. The study showed that a balanced diet and a correct dosage of phosphate binders, as well as a careful substitution with active vitamin D metabolits render a good control of calcium and phosphate serum balance, as well as an effective prevention of renal osteodystrophy development in the patients on chronic peritoneal dialysis treatment.
