Active clinical trials for "Hypocalcemia"

The objective of this study is to compare the frequency of post-thyroidectomy symptomatic and biochemical hypocalcaemia between the strategy of routine prophylactic calcium + calcitriol vs the administration of calcium guided by PTH values.

To compare intraoperative and postoperative complication rates in thyroidectomy between ligasure and traditional vascular ligation and clipping .

Calcium helps blood to clot and thereby stop bleeding. Trauma patients who experience large volume blood loss often require blood transfusions and bleeding is the most common cause of death. The purpose of this study is to see if giving intravenous calcium immediately to patients who require large volume blood transfusion will decrease transfusion requirements, vasopressor use and mortality in bleeding trauma patients.

Hypocalcaemia is an independent risk factor of TIC in elderly trauma patients. TIC combined with hypocalcemia had worse coagulation function and more serious acidosis.

Major trauma frequently occurs in the deployed, combat setting and is especially applicable in the recent conflicts with explosives dominating the combat wounded. In future near-peer conflicts we will likely face even more profound weapons including mortars and artillery. As such, the number of severely wounded will likely increase. Hypocalcemia frequently occurs after blood transfusions secondary to the preservatives in the blood products, however, recent data suggests that major trauma in and of itself is a risk factor for hypocalcemia. Calcium is a major ion involved in heart contractility and thus hypocalcemia can lead to poor contractility. Smaller studies have linked hypocalcemia to worse outcomes, but it remains unclear what causes hypocalcemia and if intervening could potentially save lives. We are seeking to address the following scientific questions, (1) Is hypocalcemia present following traumatic injury prior to transfusion during resuscitation? (2) Does hypocalcemia influence the amount of blood products transfused? (3) To what extent is hypocalcemia further exacerbated by transfusion? (4) What is the relationship between hypocalcemia following traumatic injury and mortality? We will conduct a multicenter, prospective, observational study. We will gather ionized calcium levels at 0, 3, 6, 12, 18, and 24 hours as part of scheduled calcium measurements. This will ensure that we have accurate data to assess the early and late effects of hypocalcemia throughout the course of resuscitation and hemorrhage control. These data will be captured by a trained study team personnel at every site. Our findings will inform clinical practice guidelines and optimize the care delivered in the combat and civilian trauma setting.

The goal of this National Registry is to is to collect information from patients with rare kidney diseases, so that it that can be used for research. The purpose of this research is to: Develop Clinical Guidelines for specific rare kidney diseases. These are written recommendations on how to diagnose and treat a medical condition. Audit treatments and outcomes. An audit makes checks to see if what should be done is being done and asks if it could be done better. Further the development of future treatments. Participants will be invited to participate on clinical trials and other studies. The registry has the capacity to feedback relevant information to patients and in conjunction with Patient Knows Best (Home - Patients Know Best), allows patients to provide information themselves, including their own reported quality of life and outcome measures.

Calcium is a life saving medicine in the care of parturients. It has many important uses including treatment of hypocalcemia, treatment of magnesium toxicity, prevention of hypocalcemia during blood transfusion (of citrate containing blood products), treatment of hyperkalemia, and others. Recent clinical trials also suggest that calcium given after cord clamping may decrease blood loss in patients undergoing cesarean delivery. 2 FDA approved forms of calcium can be given intravenously: calcium chloride and calcium gluconate. Over the last decade there have been times with drug shortages of either calcium chloride or calcium gluconate. So there have been and likely will continue to be times when one formulation or the other may not be adequately available. Despite the importance of calcium and the frequency in which it is used in parturients, there are no published studies in parturients to determine dose equivalence between calcium gluconate and calcium chloride. In this study the investigators will determine the population pharmacokinetics of calcium gluconate and calcium chloride in parturients and calculate the dose equivalent ratio the two drugs. This will help clinicians select appropriate doses of calcium and provide resilience to the drug supply chain in our era of frequent drug shortages.

Thyroidectomy is a standard procedure for benign and malignant pathologies of the thyroid gland. Each year, some 100 total thyroidectomies are performed in Kowloon East Cluster, Hospital Authority, Hong Kong. Total thyroidectomy is associated with voice dysfunction and temporary hypocalcaemia in up to 80% and 50%, respectively. Previous study from our institute showed a 3% rate of permanent vocal cord palsy and 16% of permanent hypoparathyroidism requiring calcium and/or vitamin D supplements. The use of dexamethasone has been studied in the past in total thyroidectomy patients and has been shown to be safe and effective in improving post-operative nausea and vomiting. No complications or drug related side effects were associated with a single dose of steroid. Recent studies have also shown that Dexamethasone is effective in improving voice outcome and hypocalcaemia in thyroidectomy patients. The investigators aim to study the effect of Dexamethasone in post-operative voice outcome and hypocalcaemia. Objective assessment of the vocal cords during phonation will be performed pre-operative and post-operatively. Serum Calcium level will be monitored.

A global, multi-center, Disease Monitoring Study (DMS) in participants with Autosomal Dominant Hypocalcemia Type 1 (ADH1) or Autosomal Dominant Hypocalcemia Type 2 (ADH2) designed to characterize ADH1 and ADH2 disease presentation and progression through retrospective (past) and longitudinal prospective (over time into the future) data collection.

Long-term conventional treatment of chronic hypoparathyroidism does not fully restore calcium homeostasis leading to increased morbidity, emergency events and reduced subjective health status. To further investigate general morbidity, hypocalcemic events, subjective and daily life performance in patients with chronic hypoparathyroidism a standardized interview as well as blood sampling and examinations such as echocardiography and renal ultrasound are performed.
