Autoimmune hemolytic anemia and thrombocytopenia attributed to an intrauterine contraceptive device.

BACKGROUND: Evans syndrome is a rare condition manifested by combined autoimmune hemolytic anemia (AIHA) and thrombocytopenia or neutropenia. It is often associated with other autoimmune disorders, immunodeficiencies, and non-Hodgkin's lymphoma. CASE REPORT: We describe a patient with Evans syndrome that may have been related to exposure to a polyethylene-based intrauterine contraceptive device (IUD). A 26-year-old white female presented with severe, symptomatic AIHA and subsequently developed severe thrombocytopenia. She had a refractory course resistant to multiple treatments including corticosteroids, intravenous immune globulin, rituximab, splenectomy, cyclophosphamide, cyclosporine, eculizumab, and plasma exchange. It was then noticed that her serum autoantibody agglutinated red blood cells (RBCs) in the presence of polyethylene glycol (PEG) but not in the absence of PEG nor when an alternative agglutination enhancing technique, low-ionic-strength solution, was used. Therefore, her polyethylene-containing IUD, which was a polyethylene frame with a levonorgestrel-releasing device, was removed. Norgestrel-dependent, platelet (PLT)-reactive antibodies were not identified by either flow cytometry or in vivo in a NOD/SCID mouse. Testing for PEG-dependent antibodies was not possible. Remission, with no requirement for RBC or PLT transfusions and return of her hemoglobin and PLT counts to normal, followed removal of the IUD. CONCLUSION: The patient's recovery after removal of the IUD and the PEG dependence of RBC agglutination suggested a possibility that the IUD may have been a contributing factor to the etiology of Evans syndrome in this patient.

Azacitidine Maintenance Therapy Post-Allogeneic Stem Cell Transplantation in Poor-Risk Acute Myeloid Leukemia.

OBJECTIVE/BACKGROUND: Allogeneic hematopoietic stem cell transplant (HSCT) is the potential curative modality for poor-risk acute myeloid leukemia (AML), relapse remains the main reason for transplant failure. Early-phase studies showed azacitidine is safe for post-transplant maintenance therapy in AML. METHODS: We performed a single institutional prospective cohort study to evaluate the benefit of azacitidine maintenance therapy following allogeneic HSCT in poor-risk AML. The main objective of this study is to generate a hypothesis aiming to optimize post-transplantation outcomes in poor-risk AML. Forty-nine adults with poor-risk AML who underwent allogeneic HSCT were evaluated in a nonrandomized prospective cohort fashion. Thirty-one participants received post-transplant azacitidine (32 mg/m2) on Days 1-5 for a 28-day treatment cycle beginning approximately 40 days after transplantation. The study was controlled using 18 matched individuals who were on a noninterventional surveillance protocol. RESULTS: The relapse rate was significantly higher in the control cohort (66.67%) versus (25.81%) in the azacitidine maintenance cohort ( p < .005). Time to relapse was significantly prolonged by azacitidine maintenance, not reached versus 4.1 months in the control arm ( p < .0001). In addition, median overall survival was lower in the control cohort at 7.6 versus 27.4 months in the interventional cohort ( p < .0001). At a median follow-up of 24 months, incidence of graft-versus-host disease (GVHD) did not differ between study groups ( p = .325). In both cohorts, minimal residual disease was correlated with higher hazard of relapse (95% confidence interval, 2.31-13.74; p < .001). CONCLUSION: We conclude that low dose azacitidine maintenance following allogeneic HSCT in poor-risk AML, decreased relapse rate, and increased both the time to relapse and overall survival without increased risk of GVHD.

Health following recovery from immune thrombotic thrombocytopenic purpura: the patient's perspective.

The impact of residual symptoms following recovery from immune-mediated thrombotic thrombocytopenic purpura (iTTP) on activities of daily living during remission is not routinely discussed or evaluated by hematologists. This study used qualitative methodology to understand 3 issues from the patient's perspective: the most important symptoms during remission, the impact of these symptoms on their daily activities, and the effectiveness of communication with hematologists. Oklahoma and Ohio patients participated in either focus groups or individual interviews. Eligibility included age ≥18 years, ADAMTS13 deficiency (<10% activity) at diagnosis or relapse, and in clinical remission (≥1 year from episode). A nonprobabilistic purposive sampling approach was used. The most important symptoms were defined as symptoms mentioned across all 7 focus groups. The interviews supplemented focus group data. The analysis focused on describing the impact of symptoms and barriers to communicating with hematologists. A total of 44 patients participated (focus groups, N = 25; interviews, N = 19). The most important symptoms affecting the patients' daily activities were cognitive issues, anxiety, depression, and fatigue. These symptoms affected patients' ability to return to their previous level of functioning and created difficulties in relationships. A key communication barrier with their hematologists was forgetting to mention these symptoms. Although hematologists pronounce patients as recovered, iTTP remains a life-changing event. Patients often did not return to their previous functioning; relationships and careers were affected. However, patients may forget to discuss these concerns with their hematologist. To improve remission care, hematologists should incorporate patient-reported outcome measures evaluating these symptoms in remission visits.
