BACKGROUND: Previous studies have shown that more than 20% of laboratories would have recommended inaccurate doses of Rh immune globulin (RhIG) in hypothetical cases. Efforts have been made in educating laboratories in correct dosing calculations; however, obstetricians are most often responsible for ordering RhIG. The objective of this study was to assess knowledge of RhIG indications and dosing among obstetrics and gynecology (OB/GYN) physicians in the United States. STUDY DESIGN AND METHODS: An anonymous 17- question online survey was distributed to all OB/GYN resident and attending physicians affiliated with US residency training programs...

Vast diversity and high specificity of antigen recognition by antibodies are hallmarks of the acquired immune system. Although the molecular mechanisms that yield the extremely large antibody repertoires are precisely understood, comprehensive description of the global antibody repertoire generated in individual bodies has been hindered by the lack of powerful measures. To obtain holistic understanding of the antibody-repertoire space, we used next-generation sequencing (NGS) to analyze the deep profiles of naive and antigen-responding repertoires of the IgM, IgG1, and IgG2c classes formed in individual mice...

Rheumatoid arthritis (RA) is a chronic inflammatory condition with variable clinical presentation and disease progression. Importantly, animal models of RA are widely used to examine disease pathophysiology/treatments. Here, we exploited known vendor colony-based differences in endocrine/immune responses to gain insight into inflammatory modulators in arthritis, utilizing the adjuvant-induced arthritis (AA) model. Our previous study found that Sprague-Dawley (SD) rats from Harlan develop more severe AA, have lower corticosteroid binding globulin, and have different patterns of cytokine activation in the hind paw, compared to SD rats from Charles River...

Acute graft versus host disease (aGVHD) remains the second leading cause of death following allogeneic hematopoietic stem cell transplant (AHSCT). Over the last five years, the progress in understanding the pathophysiology of this immune based-process helped redefine graft versus host reaction and opened new possibilities for novel preventive and therapeutic approaches. The evolution in the field of immunology widened the horizons for hematopoietic stem cell transplant leading to the availability of different stem cell sources for potential graft and incorporation of novel conditioning regimens...

Long-term antiviral prophylaxis is required to prevent hepatitis B recurrence for patients with chronic hepatitis B (CHB) after liver transplantation. We determined the long-term outcome of 265 consecutive CHB liver transplant recipients treated with entecavir monotherapy without hepatitis B immune globulin (HBIG). Viral serology, viral load, and liver biochemistry were performed at regular intervals during follow-up. The median duration of follow up was 59 months. The cumulative rates of hepatitis B surface antigen (HBsAg) seroclearance were 90% and 95% at 1 and 5 years respectively...

Miller Fisher syndrome (MFS)  was first recognized by James Collier in 1932 as a clinical triad of ataxia, areflexia, and ophthalmoplegia. Later, it was described in 1956 by Charles Miller Fisher as a possible variant of Guillain-Barré syndrome (GBS). Here, we write a case of a patient with atypical presentation of this clinical triad as the patient presented with double vision initially due to unilateral ocular involvement that progressed to bilateral ophthalmoplegia. He developed weakness of the lower extremities and areflexia subsequently...

Non-myeloablative conditioning using total lymphoid irradiation (TLI) and rabbit anti-thymocyte serum (ATS) (the murine pre-clinical equivalent of anti-thymocyte globulin/ATG) facilitates immune tolerance after bone marrow transplantation (BMT) across major histocompatibility complex (MHC) disparities and may be a useful strategy for non-malignant disorders. We previously reported that donor effector T cell function and GVHD are regulated via recipient invariant natural killer T cell (iNKT cell) IL-4-driven expansion of donor Foxp3(+) naturally occurring Treg...

Complete donor chimerism is strongly associated with complete remission after allogeneic stem cell transplantation (allo-SCT) in patients with hematological malignancies. Donor-derived allo-immune responses are eliminating the residual host hematopoiesis and thereby mediate the conversion to complete donor chimerism. Recently, CMV reactivation has been described to enhance overall T-cell reconstitution, to increase graft-versus-host disease (GvHD) incidence and to reduce the leukemia relapse risk. However, the link between CMV and allo-immune responses is still unclear...

BACKGROUND: Anti-thymocyte globulin (ATG) is used to prevent graft-versus-host disease (GvHD) after allogeneic haemopoietic cell transplantation (HCT). However, ATG can also cause delayed immune reconstitution of T cells, negatively affecting survival. We studied the relation between exposure to ATG and clinical outcomes in adult patients with acute leukaemia and myelodysplastic syndrome. METHODS: We did a retrospective, pharmacokinetic-pharmacodynamic analysis of data from patients with acute lymphoid leukaemia, acute myeloid leukaemia, or myelodysplastic syndrome receiving their first T-cell repleted allogeneic peripheral blood stem cell HCT with ATG (thymoglobulin) as part of non-myeloablative conditioning from March 1, 2004, to June 1, 2015...

Wiskott-Aldrich syndrome is a severe X-linked recessive immune deficiency disorder. A scoring system of Wiskott-Aldrich syndrome severity (0.5-5) distinguishes 2 phenotypes: X-linked thrombocytopenia and classic Wiskott-Aldrich syndrome. Hematopoietic cell transplantation is curative for Wiskott-Aldrich syndrome, however the use of unrelated umbilical cord blood transplantation has seldom been described. We analyzed umbilical cord blood transplantation outcomes for 90 patients. Median age at umbilical cord blood transplantation was 1...

Autologous haematopoietic stem cell transplantation (HSCT) is the only treatment that is able to induce long-term, drug-free and symptom-free remission in several refractory autoimmune rheumatic diseases. Over 3,000 HSCT procedures for rheumatic and nonrheumatic severe autoimmune diseases have been performed worldwide. Specific conditioning regimens are currently used to eradicate the autoreactive immunological memory of patients. Although in vivo immune cell depletion with antithymocyte globulin or anti-CD52 is the norm for many regimens, ex vivo selection of CD34(+) stem cells from the graft is controversial...

Immune thrombocytopenia (ITP) is a disease characterized by isolated thrombocytopenia. Abnormal effector T cell activation is an important mechanism in the pathogenesis of ITP. Regulatory T cells (Treg) have a strong immunosuppressive function for T cell activation and their importance in the pathophysiology and clinical treatment of ITP has been confirmed. Myeloid-derived suppressor cells (MDSCs) are other immunosuppressive cells, which can also suppress T cell activation by secreting arginase, iNOS and ROS, and are essential for Treg cells' differentiation and maturation...
