NCT ID: NCT06160479 Active, not recruiting - Clinical trials for Hypocalcemia in Pregnancy

The Incidence of Hypocalcemia in Pregnant Women at Siriraj Hospital

HypoCal
Start date: May 5, 2022
Phase: N/A
Study type: Interventional

Calcium is an essential element for fundamental physiological functions and during pregnancy. However, higher calcium intake can induce constipation, flatulence, nausea, or kidney stones. This study aims to evaluate the incidence of hypocalcemia among pregnant women in the first half of pregnancy in Thailand. Also, Comparison of calcium level in pregnant women in the third trimester who received and not received calcium during pregnancy.

NCT ID: NCT06065852 Recruiting - Fabry Disease Clinical Trials

National Registry of Rare Kidney Diseases

RaDaR
Start date: November 6, 2009
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT05973747 Completed - Pregnancy Related Clinical Trials

Pharmacokinetic Equivalence of Calcium Gluconate and Calcium Chloride in Parturients

Start date: August 19, 2023
Phase: Early Phase 1
Study type: Interventional

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.

NCT ID: NCT05953376 Not yet recruiting - Trauma Clinical Trials

Empiric Calcium in Massive Transfusion

Start date: January 2025
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT05885256 Recruiting - Hypocalcemia Clinical Trials

Clinical Assessment of Low Calcium In traUMa (CALCIUM)

CALCIUM
Start date: September 1, 2022
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT05732883 Not yet recruiting - Hypocalcemia Clinical Trials

The Use of Dexamethasone in Total Thyroidectomy to Improve Voice Outcome and Hypocalcaemia

Start date: January 1, 2024
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT05684536 Not yet recruiting - Hypocalcemia Clinical Trials

Start date: January 15, 2023
Phase: N/A
Study type: Interventional

CALIBRATE
Start date: January 6, 2023
Phase: Phase 3
Study type: Interventional

NCT ID: NCT05586529 Recruiting - Hypocalcemia Clinical Trials

Effect of Preoperative High-dose Cholecalciferol in Prevention of Post-thyroidectomy Hypocalcaemia

Start date: November 1, 2022
Phase: N/A
Study type: Interventional

Hypocalcaemia after thyroidectomy is observed with increasing frequency, often resulting in prolonged hospital stay with increased use of resources, delayed return to work and reduced quality of life. The administration of vitamin D is essential in the therapy of postoperative hypocalcaemia. What has not been examined so far is whether and how routine preoperative cholecalciferol prophylaxis can help to prevent postoperative hypocalcaemia

NCT ID: NCT05585593 Recruiting - Quality of Life Clinical Trials

Registry for Hypoparathyroidism Wuerzburg

Start date: October 18, 2017
Phase:
Study type: Observational

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.
