Filter by:This study aims to investigate the changes in cardiac functions, especially myocardial performance index (MPI), in patients who underwent parathyroidectomy for secondary hyperparathyroidism. Participants who underwent parathyroidectomy for secondary hyperparathyroidism between June 2010 and September 2021 were analyzed retrospectively. The participants were divided into two groups: those who underwent total parathyroidectomy (group 1) and those who underwent subtotal parathyroidectomy (group 2). The groups were compared according to the echocardiogram findings performed in the preoperative period and the postoperative sixth month. In addition, cardiac structure, systolic and diastolic function, especially myocardial performance index, were evaluated by echocardiography and Doppler imaging.
Secondary hyperparathyroidism (SHPT) is a common serious complication in the maintenance process of hemodialysis patients, characterized by diffuse or nodular hyperplasia of parathyroid glands. Parathyroidectomy for patients with drug-refractory SHPT is recommended in the clinical practice guidelines of the Global Organization for Improving Prognosis in Kidney Disease (KDIGO) and the Japanese Dialysis Therapy Society (JSDT) . Therefore, accurate localization and detection of parathyroid abnormalities is the key to avoid persistent recurrence of the disease. However, the sensitivity and specificity of the existing ultrasound and 99MTC-MIBI diagnosis are limited. CT examination is radiative and requires iodine contrast medium with nephrotoxicity, which may require timely dialysis and long-term monitoring for hemodialysis patients. 3T MRI has no radiation and does not need to use iodine contrast agent, which can well detect parathyroid lesions . Previous studies have reported that 3T MRI can diagnose primary hyperparathyroidism (PHPT), but the diagnostic efficacy of SHPT is still unclear. Therefore, this study aims to evaluate the preoperative diagnostic value of non-enhanced 3T MRI compared with 4DCT in patients with secondary hyperparathyroidism after hemodialysis.
The study is being conducted to evaluate the tolerability, pharmacokinetics and pharmacodynamics of SHR6508 for Chinese patients with secondary hyperparathyroidism of chronic kidney disease treated by maintenance hemodialysis
This is a pilot randomized controlled trial aimed to evaluate the effect of teriparatide on the clinical course of hypocalcemia after parathyroidectomy for secondary hyperparathyroidism in dialysis-dependent patients.
Secondary hyperparathyroidism (SHPT) is a multisystemic syndrome that affects calcium and bone homeostasis in patients with chronic kidney disease (CKD). Despite medical treatment, 1-2% of patients require parathyroidectomy anually. The use of an intraoperative paratohormone protocol (IOPTH) to predict cure still in debate, due to the lack of standardized protocols, the use of different assays and uneven PTH clearance. The aim of this study was to determine the diagnostic accuracy of an IOPTH in patients with SHPT for predicting successful surgery after parathyroidectomy.
This is a prospective cohort study aimed to evaluate change of cardiovascular calcification after parathyroidectomy in patients with end-stage renal disease on dialysis compared with control group on conservative treatment.
The purpose of this study is to evaluate the efficacy and the safety of KHK7580 orally administered once daily for 52 weeks compared to cinacalcet hydrochloride as an active control in subjects with secondary hyperparathyroidism receiving hemodialysis in China, Korea, Hong Kong and Taiwan.
