This study tested two different chemotherapy drugs (Treosulfan and Busulfan) given before a stem cell transplant in 106 children with serious non-cancer diseases like immune disorders, metabolic diseases, blood disorders, and bone marrow failure. The goal was to see which drug le…

This study looked at 50 patients who needed a stem cell transplant from a partially matched donor but had antibodies that could attack the donor cells. Before transplant, they received a blood purification treatment called protein A immunoadsorption to remove those antibodies, so…

This study looked at whether touch-massage can reduce anxiety in people with blood disorders (like leukemia or lymphoma) who are hospitalized in a sterile, isolated room. Sixty-two patients received three massage sessions, and researchers measured their anxiety levels before and …

This study tested a monthly online peer support group for young adults (ages 18-39) who had received a stem cell transplant. The group met for one hour over six months, led by a nurse and social worker. The goal was to see if the program was practical and helpful for reducing anx…

This study tested whether montelukast (Singulair), a common asthma drug, can reduce the number and severity of infusion reactions in people receiving monoclonal antibody treatments for blood disorders. Forty adults were given montelukast along with standard premedication before t…

This study looked for a virus called HHV6 in the skin and blood of 37 adults with blood cancers who developed a rash during hospital stays. The goal was to see if the virus is linked to the rash, which could help doctors diagnose and treat the rash more effectively. The study is …

This study analyzed DNA from 9 patients with primary immune deficiencies whose genetic cause was unknown. Researchers used whole exome or genome sequencing to look for new mutations that might explain their condition. The goal was to identify new inborn errors of immunity, which …

This study looked at whether it is safe to lower the number of platelets needed before placing a central line (a special IV) in patients with blood disorders. Normally, patients get a platelet transfusion if their count is below 50, but this study tested a lower trigger of 10. Th…

This study looked at whether ultrasound and stiffness measurements of the liver and spleen can predict a serious condition called portal hypertension in people with common variable immunodeficiency (CVID). Researchers examined 250 CVID patients during routine visits, using non-in…

This study looked for hidden immune system problems in adults who get frequent or severe bacterial infections, like pneumonia or meningitis. Researchers screened 120 adults aged 18-65 to see how many had an undiagnosed primary immunodeficiency. The goal was to find out if these c…

This observational study compared blood samples from 24 people with antibody deficiency (CVID) and healthy volunteers. Researchers used advanced technology to measure how different immune cells respond to various triggers. The goal was to find patterns that could improve diagnosi…

This study looked at 99 women with primary immune deficiency to learn more about their pregnancies and birth outcomes. Researchers tracked infections during pregnancy and after birth, as well as how well contraception worked. The goal is to help doctors give better advice to wome…
