Memphis, TennesseeAges Any age - NCT06857630Recruiting
Hemoglobin levels and kidney injury in emergency surgery
This trial looks at whether a patient's hemoglobin level (a measure of red blood cells) before emergency surgery can help predict the risk of acute kidney injury afterward. It aims to find if early detection can prevent kidney damage.
SamsunAges 18–80 - NCT06568315RecruitingPhase 3
Calcium plus multivitamins for mother and baby
This study tests whether taking a daily multivitamin with calcium, in addition to standard prenatal vitamins, improves iron levels and health for you and your baby. You would switch from your usual iron folic acid pills to the study supplements.
OuagadougouAges 15 years+ - NCT06718439Recruiting
Comparing blood transfusion levels during and after surgery
This trial tests whether giving blood transfusions sooner or later during surgery affects recovery for patients with low hemoglobin. It compares using a liberal (higher) threshold to give blood versus a more restrictive (lower) threshold.
Ottawa, OntarioAges 18 years+ - NCT07673302Recruiting
Study of drugs to boost fetal hemoglobin in beta thalassemia
This trial tests if certain drugs can safely increase fetal hemoglobin (a type of hemoglobin that helps carry oxygen) in people with beta thalassemia major. It may offer a new way to manage the condition and reduce the need for transfusions.
Rawalpindi, Punjab ProvinceAges Any age - NCT06767722Recruiting
Lifestyle program for high blood sugar in early pregnancy
This trial tests if a lifestyle program (diet and activity changes) can help pregnant women who have slightly high blood sugar in early pregnancy. It aims to improve glucose levels and reduce complications for both mother and baby.
Guangzhou, GuangdongAges 18–55 - NCT06906835Recruiting
Comparing two blood tests to guide iron treatment in dialysis patients
This trial tests whether a new blood test (reticulocyte hemoglobin) is better than the usual iron test (transferrin saturation) for guiding when to give iron to people on dialysis. If you have anemia (low red blood cells) from kidney disease, this study may help doctors find the best way to treat your iron levels.
Pathumwan, BangkokAges 18–80 - NCT07743242Recruiting
Study of hemolytic anemia in antiphospholipid syndrome
This study looks at how autoimmune hemolytic anemia (when the body attacks its own red blood cells) relates to antiphospholipid syndrome (a condition that increases blood clot risk). It aims to better understand this connection, which may help improve care for people with both conditions.
Al Khārjah, Kharga OasisAges 18 years+ - NCT06067399Recruiting
Red blood cell width and blood sugar in type 2 diabetes
This study looks at two blood test results—HbA1c (average blood sugar) and red blood cell width (RDW)—in people with type 2 diabetes whose blood sugar is not well controlled. The goal is to see how these two measurements relate after improving blood sugar management.
Al KhārjahAges 40 years+ - NCT05735717RecruitingPhase 2
T-cell transplant using depleted receptors for blood cancers
This Phase 2 study tests a specialized stem cell transplant that removes certain immune “T-cell” receptors to help treat blood cancers like acute leukemia. It may help your body rebuild a healthier immune system after high-dose treatment.
Minneapolis, MinnesotaAges Up to 60 years - NCT05170230Recruiting
Terlipressin or carbetocin shots to reduce bleeding in fibroid surgery
This study compares two different medications given as shots during laparoscopic fibroid (myomectomy) surgery. The goal is to see which shot better reduces blood loss and helps keep hemoglobin (a blood oxygen-carrying protein) from dropping too much.
MaadiAges 16–45 - NCT05266534Recruiting
Terlipressin or oxytocin during open fibroid surgery
This trial compares two injected medicines (terlipressin vs carbetocin) given into the uterus during open fibroid (myomectomy) surgery to see which one reduces blood loss and helps maintain hemoglobin. It may help patients by targeting lower bleeding during surgery.
MaadiAges 16–40 - NCT05488054Recruiting
Checking oxygen levels and blood counts during ACL rehab
This study measures oxygen levels in your muscles and hemoglobin (a blood protein that carries oxygen) while you recover after arthroscopic hip surgery. It may help researchers understand how the body responds during rehabilitation after orthopedic surgery.
Avon, OhioAges 14–30 - NCT05977686Recruiting
Hemoglobin testing in pregnant adults
This trial studies how hemoglobin (an oxygen-carrying protein in blood) is checked during pregnancy. It may help improve or confirm the best way to monitor blood health in pregnant patients.
Washington D.C., District of ColumbiaAges 18–50 - NCT06184373Recruiting
Early glucose monitoring after gestational diabetes pilot
This study tests a continuous glucose monitor (a small patch that tracks your blood sugar) for a few weeks after you give birth. It aims to see if this tool can help women who recently had gestational diabetes better understand their blood sugar levels after delivery.
