Non-motor Comorbidity of Myasthenia Gravis: Myasthenia Gravis as a Systemic Immunological Disorder Involving Non-motor Systems.

Intern Med 2018 Dec 18. Epub 2018 Dec 18.

Department of Neurology, Brain Science Centre, Sapporo City General Hospital, Japan.

To explore non-motor comorbidities of myasthenia gravis (MG), we present two cases of thymoma-associated MG patients. Alopecia, pure red cell aplasia, and thymoma- associated multiorgan autoimmunity were observed in Case 1, and alopecia, thrombocytopenia, hypogammaglobulinemia and nephrotic syndrome were observed in Case 2. In both cases, autoreactive T lymphocytes inappropriately stimulated by thymus tissue may have played key roles in generating the various autoimmune-associated symptoms. Read More

[Pure red cell aplasia following the rapid reduction and discontinuation of cyclosporine for mixed chimerism after allogeneic bone marrow transplantation].

Rinsho Ketsueki 2018 ;59(11):2408-2412

Department of Pediatrics, Kyoto Prefectural University of Medicine.

A 19-year-old male with therapy-related myelodysplastic syndrome underwent allogeneic bone marrow transplantation with reduced-intensity conditioning from his HLA-identical sibling whose ABO blood type exhibited major incompatibility with the patient. After post-transplantation 1 month, chimerism analysis of the bone marrow revealed mixed chimerism with 30% of recipient cells, and after post-transplantation 3 months, complete remission was maintained; however, recipient granulocytes were elevated up to 50% per the chimerism analysis. Next, pancytopenia developed following the rapid discontinuation of the immunosuppressive agent. Read More

Pui Y Lee

Front Pediatr 2018 18;6:282. Epub 2018 Oct 18.

Division of Allergy, Immunology and Rheumatology, Boston Children's Hospital, Boston, MA, United States.

Deficiency of adenosine deaminase 2 (DADA2) is a monogenic form of systemic vasculopathy that often presents during early childhood. Linked to biallelic mutations in (previously ), DADA2 was initially described as a syndrome of recurrent fever, livedo racemosa, early-onset strokes, and peripheral vasculopathy that resembles polyarteritis nodosum. However, the wide spectrum of clinical findings and heterogeneity of disease, even among family members with identical mutations, is increasingly recognized. Read More

Frequent mutations in CD8 T cells from patients with pure red cell aplasia.

Blood Adv 2018 Oct;2(20):2704-2712

Division of Hematology, Department of Internal Medicine, School of Medicine.

Dysregulation of T-cell-mediated immunity is responsible for acquired pure red cell aplasia (PRCA). Although mutations are frequently detected in patients with T-cell large granular lymphocytic leukemia (T-LGLL), which is often complicated by PRCA and which is also reported to be associated with acquired aplastic anemia (AA) and myelodysplastic syndrome (MDS), whether -mutated T cells are involved in the pathophysiology of PRCA and other types of bone marrow failure remains unknown. We performed mutation analyses of the peripheral blood mononuclear cells from PRCA patients (n = 42), AA (n = 54), AA-paroxysmal nocturnal hemoglobinuria (AA-PNH; n = 7), and MDS (n = 21) using an allele-specific polymerase chain reaction and amplicon sequencing.

Eltrombopag for the Treatment of Refractory Pure RBC Aplasia after Major ABO Incompatible Hematopoietic Stem Cell Transplantation.

Biol Blood Marrow Transplant 2018 Aug 21;24(8):1765-1770. Epub 2018 Apr 21.

A.O.U. Città della Salute e della Scienza, Dipartimento di Oncologia, SSD Trapianto allogenico di cellule staminali, Turin, Italy.

Pure RBC aplasia (PRCS) is a well-recognized complication after allogeneic hematopoietic stem cell transplantation (HSCT). Many therapeutic options are available to treat this condition, including erythropoietin, rituximab, bortezomib, plasma exchange, immunoadsorption, donor lymphocyte infusion, mesenchymal stem cells, antithymocyte globulin, and high-dose steroids; however, treatment outcomes are often variable and can sometimes lead to disappointing results. In this brief article we report our experience with 2 patients with PRCA after major ABO-incompatible HSCT who were resistant to multiple therapeutic interventions and who eventually benefited from treatment with eltrombopag, a thrombopoietin mimetic approved by the US Food and Drug Administration for the treatment of patients with immune thrombocytopenic purpura or severe aplastic anemia refractory to immunosuppressive agents or not eligible for HSCT.

The devil is in the details: retention of recipient group A type 5 years after a successful allogeneic bone marrow transplant from a group O donor.

Immunohematology 2018 Jan;33(1):19-22

Michigan Medicine University of Michigan Ann Arbor, MI.

Conclusions: ABO-incompatible (ABOi) hematopoietic stem cell transplants (HSCTs) can present challenges in the blood bank. During transplantation, patients receive components that are ABO-compatible with both the donor graft and recipient; this practice can strain group O red blood cell (RBC) inventories.1 In addition, there are risks for acute hemolysis at the time of infusion and in the early post-transplant period.
