Aug 29th, 2022 - Patients with primary antibody deficiency (PAD) are predisposed to develop meningoencephalitis, often considered to be enteroviral. However, there is a paucity of literature on this subject, and there are no studies from developing countries. We a...

Aug 17th, 2022 - A better understanding of COVID-19 in people with primary immunodeficiency (PI), rare inherited defects in the immune system, is important for protecting this population, especially as population-wide approaches to mitigation change. COVID-19 outc...

Aug 13th, 2022 - Many immunocompromised patients mount suboptimal humoral immunity after SARS-CoV-2 mRNA vaccination. Here, we assessed the single-cell profile of SARS-CoV-2-specific T cells post-mRNA vaccination in healthy individuals and patients with various fo...

Aug 8th, 2022 - X-linked agammaglobulinemia (XLA) is an inborn error of immunity characterized by insufficient production of immunoglobulins and lack of measurable antibody response to vaccines. The rise of novel infections limits the protective effect of immunog...

Jul 16th, 2022 - Inborn errors of immunity (IEI) represent a heterogeneous large group of genetic disorders characterized by susceptibility of affected individuals to recurrent infections, autoimmune/inflammatory diseases, allergy, and malignancy. We aimed to repo...

Apr 11th, 2022 - Individuals with primary and secondary antibody immunodeficiency are at higher risk for severe COVID-19 disease. Humoral immunity is thought to be the predominant protection against COVID-19, however mRNA vaccines have been shown to elicit both an...

Aug 24th, 2021 - The purpose of this study is to determine the pharmacokinetics, efficacy and safety of Immune Globulin Intravenous (Human), 10% TVR (Triple Virally Reduced) Solution in subjects with primary immunodeficiency (PID) manifesting as hypo- or agammaglo...

Apr 8th, 2021 - PRIMARY OBJECTIVES: I. To estimate the biologic target activity of dasatinib in CLL patients found to have pre-treatment in vitro dasatinib cytotoxicity (as defined by a >= 50% decrease in absolute lymphocyte count and/or bone marrow CLL count and...

Aug 24th, 2020 - The purpose of this study is to assess the safety/tolerability and efficacy of using ustekinumab in subjects with common variable immunodeficiency CVID or selective IgG subclass deficiency (functional agammaglobulinemia) who have associated sympto...

May 31st, 2018 - Common variable immune deficiency (CVID), specific antibody deficiency (SAD), and X-linked agammaglobulinemia (XLA) are among the most common primary antibody deficiencies in which the mainstay of treatment is gammaglobulin replacement. The use of...

Dec 20th, 2020 - John C. Byrd, MD In a presentation at the inaugural ASH Meeting on Hematologic Malignancies, John C. Byrd, MD, discussed what his clinical experience has revealed about the optimal use of ibrutinib (Imbruvica) and idelalisib (Zydelig) in chronic ...

Dec 5th, 2020 - Jennifer R. Brown, MD, PhD Jennifer R. Brown, MD, PhD, and John Byrd, MD, leading researchers in the emerging field of Bruton tyrosine kinase (BTK) inhibition in chronic lymphocytic leukemia (CLL) and other B-cell malignancies, discussed key ques...

Dec 5th, 2020 - Krithika Subramanian, PhD Less than 5 years after Bruton tyrosine kinase (BTK) inhibition was introduced in hematologic malignancies, the need for strategies to address primary and secondary mechanisms of resistance has emerged. The robust poten...

Oct 20th, 2020 - NEW YORK (Reuters Health) - Clinical outcomes of COVID-19 in patients with primary immunodeficiency diseases range from mild illness to death, according to a small case series. "We were first surprised that we had only a few cases considering how ...
