Diabetes insipidus

This study tests whether giving calcium before reaching the hospital and vasopressin early in the hospital can reduce deaths in people with severe bleeding from injury. About 1050 adults at risk of hemorrhagic shock will be randomly assigned to receive these treatments or placebo…

This phase II trial is testing whether giving a lower dose of radiation after chemotherapy can effectively treat children and young adults with central nervous system germinomas, a type of brain tumor. The study will enroll 240 participants aged 3 to 29. After initial chemotherap…

This study tests whether giving the drug vasopressin earlier or later during septic shock leads to better outcomes. Researchers will use a computer alert system to randomly assign 300 ICU patients to early or standard timing. The goal is to see if the timing can be reliably contr…

This study tests whether giving vasopressin early, along with norepinephrine, is better than waiting to use it as a rescue treatment for people with septic shock. About 2,800 critically ill adults will be randomly assigned to one of two strategies. The main goal is to see which a…

This study tests four different drugs (norepinephrine, epinephrine, phenylephrine, and vasopressin) in ICU patients with shock that doesn't improve with fluids. The goal is to see which drug causes fewer dangerous heart rhythm problems and improves survival. About 836 adults will…

This study tests whether giving a combination of three drugs (epinephrine, vasopressin, and a steroid) during emergency treatment for out-of-hospital cardiac arrest can restart the heart and improve survival compared to the standard drug epinephrine alone. About 1,344 adults in T…

This study compares a new diagnostic test using mannitol infusion to the standard hypertonic saline test for diagnosing the cause of polyuria-polydipsia syndrome (excessive urination and thirst). Researchers will enroll 144 adults to see if the mannitol test is as accurate and mo…

This early-phase trial is testing whether a single dose of a hormone pill can help diagnose oxytocin deficiency in young people with hypopituitarism. Researchers will give the pill to 20 participants and measure oxytocin-related substances in blood and saliva. The goal is to deve…

This study looks at two substances in the blood—endocan and copeptin—in 40 premature babies born between 28 and 36 weeks who have breathing trouble (respiratory distress syndrome). Researchers will measure these markers on the first day of life to see if they can predict how seve…

This study compares two types of ultrasound-guided nerve blocks for pain control after open kidney removal surgery. Ninety adults will receive either a rhomboid intercostal sub-serratus plane block or an external oblique intercostal block. Researchers will measure how long it tak…

This study tests whether a nasal spray containing oxytocin can help reduce anxiety and improve emotional well-being in adults with central diabetes insipidus, a condition where the body lacks a key hormone. Participants will receive either oxytocin or a placebo spray for several …

This study tests whether letting a bladder catheter fall out on its own (passive removal) is better than having a nurse pull it out (active removal) after urological surgery. 160 men will be randomly assigned to one method. Researchers will measure satisfaction, pain, and anxiety…

This phase 2 trial tests whether oxytocin nasal spray can improve sexual well-being in people with central diabetes insipidus, a condition that also causes oxytocin deficiency. The study includes 42 participants (patients and healthy controls) and uses a double-blind, placebo-con…

This pilot study is testing whether an oxytocin nasal spray can help with anxiety, depression, and social functioning in adults with arginine-vasopressin deficiency, a rare hormone disorder. In the first part, 30 participants will receive single doses of oxytocin or placebo and c…

This study tests whether a smart water bottle that lights up when you're behind on drinking can help college students drink more water. Thirty students who currently drink less than recommended will use the bottle for a period, along with tracking their urine color and thirst. Th…

This study takes tissue samples from women having planned C-sections and tests four drugs (ephedrine, phenylephrine, norepinephrine, vasopressin) in a dish to see how they affect womb muscle and umbilical blood vessels. The goal is to understand which drugs might be safer for mot…

This study is for older adults, including those in the hospital or with low priority care needs. Researchers want to see if newer methods, like body scans and blood tests, can better detect malnutrition and kidney problems than current standard tests. The goal is to make diagnosi…

This study looks at whether measuring a substance called copeptin in the blood can help doctors diagnose central diabetes insipidus (CDI) in children after brain surgery. CDI causes extreme thirst and frequent urination due to a hormone imbalance. The study will track copeptin le…

This study tests whether music enhanced with sonic augmentation technology can increase oxytocin (a hormone linked to social bonding) with few side effects. Researchers will compare the modified music to regular music in 22 healthy adults and patients with AVP-deficiency. The goa…

This study tests a new method to help patients understand complex spine or prostate surgeries before they agree to them. Instead of just reading a form, patients watch multimedia content and answer questions to check their understanding. The goal is to see if this approach makes …

This study looks at how well three AI models—ChatGPT, Gemini, and Deepseek—can diagnose and suggest treatments for urology diseases. Researchers will use 800 past patient records from four hospitals to check the AI's accuracy and usefulness. The goal is to understand if AI can he…

This study is testing whether taking estrogen pills (estradiol valerate or ethinylestradiol) can safely trigger the release of oxytocin, a hormone important for social bonding and childbirth. Researchers will measure oxytocin levels in 28 healthy volunteers and patients with AVP …

This study looks at the best way to stop the blood pressure medication vasopressin in people with septic shock. It compares slowly reducing the dose versus stopping it all at once. The goal is to see which method causes fewer dangerous drops in blood pressure. The study involves …

This study is building a worldwide registry for people with Wolfram syndrome, a rare genetic disorder causing diabetes, vision loss, and hearing problems. Researchers will track how the disease progresses over time and analyze participants' genetic information. The goal is to bet…
