Assessment of calcium balance in patients on hemodialysis, based on ionized calcium and parathyroid hormone responses.
BACKGROUND Identification of the underlying causes of secondary hyperparathyroidism (SHPT) in individual patients on hemodialysis (HD) is hampered by the lack of clinically reliable information on calcium balance. The aim of this study was to assess calcium balance during HD sessions with a method that is applicable in day-to-day practice. METHODS Plasma ionized calcium (pCa2+) and parathyroi...
متن کاملParathyroid hormone secretion in low calcium intake smokers.
Dr B. J. Boucher raises the valid issue concerning the association between smoking and the reduction in serum parathyroid hormone (PTH) (Boucher, 2001). With regard to observing this concern in our study (Bonofiglio et al. 2000), it is my pleasure to underscore the following points. First the influence of smoking has been ruled out in girls, since a negligible percentage of them (3) were smoker...
متن کاملStatus of Vitamin D, Calcium and Parathyroid Hormone Levels & Hepatorenal Function in Untreated Pulmonary Tuberculosis: A Matched Case-Control Study
Background and Objective: Tuberculosis (TB) remains an ongoing major public health problem in the world. In recent years, experimental evidenc suggests a link between TB and Vitamin (Vit) D. This study was conducted to determine serum Vit D, calcium (Ca), phosphorus (P), and parathormone (PTH) levels in untreated pulmonary TB (PTB) patients. Materials and Methods: In this case control study, 5...
متن کاملPosttransplantation hyperparathyroidism: demonstration of retained control of parathyroid function by plasma ionized calcium.
Persistent hyperparathyroidism is a common complication of successful renal transplantation. This study sought to address several generally held assumptions concerning this endocrine disorder, i.e., it represents an autonomous condition that involutes with time. Eight normal subjects and 13 renal transplant patients with hyperparathyroidism were studied. Ten blood samples for simultaneous measu...
متن کاملAltered diurnal regulation of blood ionized calcium and serum parathyroid hormone concentrations during parenteral nutrition.
BACKGROUND Little is known about parathyroid gland function in patients receiving total parenteral nutrition (TPN). OBJECTIVE Our objective was to determine whether parathyroid gland function is abnormal in TPN recipients. DESIGN Six patients with a mean (+/-1 SD) age of 45.5 +/- 8.0 y who had been receiving TPN for 18.7 +/- 2. 8 y underwent bone biopsy, bone mass measurements with dual-ene...
