Background: A prospective cohort of Inherited Bone Marrow Failure Syndrome (IBMFS) will provide new information regarding cancer rates and types in these disorders. Pathogenic variant(s) in IBMFS genes are relevant to carcinogenesis in sporadic cancers. Patients with IBMFS who develop cancer differ in their genetic and/or environmental features from patients with IBMFS who do not develop cancer. These cancer-...

Background: Idiopathic CD4+ lymphocytopenia (ICL) is a condition in which there is a decreased level of CD4+ lymphocytes (a type of white blood cell), which can lead to opportunistic infections or autoimmune disorders and diseases.

Background: Progressive multifocal leukoencephalopathy (PML) is a brain infection. It is caused by a virus. PML can happen in people with a weakened immune system. PML is associated with cognitive and visual impairment as well as motor and speech disturbances. There is no treatment for PML. Researchers want to see if a new drug can help.

Summary: The purpose of this study is to determine whether bilateral orthotopic lung transplantation (BOLT) followed by cadaveric partially-matched hematopoietic stem cell transplantation (HSCT) is safe and effective for patients aged 5-45 years with primary immunodeficiency (PID) and end-stage lung disease.

Summary: Febrile aplasia is a common occurrence in children/adults treated with chemotherapy for malignant blood diseases or solid cancers. This acquired deficiency of immunity mainly causes susceptibility to bacterial and fungal infections, pathogens normally recognized by specific receptors of innate immunity (Pattern Recognition Receptor, PRR). Thus, the febrile episodes in the context of post-chemother...

Summary: The main goal of the project is provison of a global registry for mitochondrial disorders to harmonize previous national registries, enable world-wide participation and facilitate natural history studies, definition of outcome measures and conduction of clinical trials.

Summary: The aim of this study is to determine the effect of the cold steam application on body temperature in combination with the treatment algorithm in fever management in children with febrile neutropenia.

Summary: The aim of this study is to evaluate the efficacy of dexamethasone in hospitalized adults with COVID-19 pneumonia who do not require supplementary oxygen on admission, but have high risk of developing acute respiratory distress syndrome (ARDS). This is a prospective, multicenter, phase 4, parallel-group, randomized and controlled trial that is open-label to investigators, participants and clinical...

Summary: Hepatitis B virus (HBV) infection is still a major public health problem worldwide. There are 260 million people with chronic HBV infection in the world, and 890,000 people die of HBV-related diseases annually. Mother-to-child transmission (MTCT) is still the main transmission route of HBV in high-endemic areas, such as China, sub-Saharan Africa, etc. Fortunately, the morbidity of HBV infection is...

Summary: This study hypothesizes that a reduced intensity immunosuppressive preparative regimen will establish engraftment of donor hematopoietic cells with acceptable early and delayed toxicity in patients with immune function disorders. A regimen that maximizes host immune suppression is expected to reduce graft rejection and optimize donor cell engraftment.

Summary: This is a standard of care treatment guideline for allogeneic hematopoetic stem cell transplant (HSCT) in patients with primary immune deficiencies.

Summary: The aim of the study is to identify clinical and laboratory parameters, present at the time of initial evaluation that could help predict which children with cancer, fever, and neutropenia will be at risk for developing clinically documented infections and/ or complications.
