Testing a hormone level to diagnose thirst and urination problems in children
Part of Hormones & metabolism, Kidney & urinary, Women’s health & pregnancy clinical trials.
This study uses a hormone test (copeptin) after giving arginine to help tell apart two conditions that cause excessive thirst and urination in children. It aims to see if this test can accurately diagnose the problem without more invasive procedures.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your child is between 2 and 18 years old.
- Your child drinks and urinates a lot (over 1.5 liters of urine per day for a 30 kg child).
- The initial hormone test showed low copeptin (under 30 pmol/L).
- You and the other parent agree to let your child take part in the study.

This study helps doctors figure out why some people drink and urinate excessively. Researchers will measure a hormone called copeptin in your blood after giving you fluids, to find out if your excessive drinking and urination is caused by a specific hormone problem (AVP deficiency) or something else.
This study tests whether a low dose of MDMA, compared to a placebo, changes oxytocin levels in people with a condition called arginine vasopressin deficiency (also known as central diabetes insipidus). The goal is to understand the role of oxytocin in this condition and explore potential treatment insights.
This study follows children after brain surgery to see how a substance called copeptin (a marker in the blood) changes and whether it can help doctors spot a condition that causes too much thirst and urination (diabetes insipidus) early. It may lead to better care for children in the ICU.
This study tests a new drug called NDI-5001 in adult men with a specific genetic form of nephrogenic diabetes insipidus (a condition where the kidneys cannot concentrate urine properly). The trial checks whether the drug is safe, how your body handles it, and whether it might help reduce excessive urination and thirst.
This study tests if a blood test for copeptin can help diagnose and classify bedwetting in children who only wet at night and have no other bladder issues. It may help tailor treatment in the future.
This study looks at how drinking more water affects thirst, brain function, and kidneys in healthy young adults. You may join if you normally drink very little water and meet specific health criteria.
