Autoimmune thrombocytopenic purpura (ATP) and thrombotic thrombocytopenic purpura (TTP) are each well recognized clinical syndromes which may appear as single episodes or may have chronic relapsing courses. We present four patients negative for human immunodeficiency virus (HIV) infection who appear to have both diagnoses with either concomitant or intermingled episodes, and we review seven additional patients reported in the literature with similar features. All four of our patients are female, two have underlying connective tissue disorders, and their ATP processes came to our attention because of incomplete response of the platelet count to plasma exchange therapy (PEX) during a TTP phase (Cases 1 and 2) or development of thrombocytopenia in the absence of microangiopathy on the background of prior typical TTP episodes (Cases 3 and 4). Recognition of the ATP diagnosis in each case resulted in discontinuation of PEX (Cases 1 and 2) or not instituting PEX (Cases 3 and 4). In each instance, a satisfactory rise in platelet count followed treatment for ATP. Based upon this experience, we conclude that some individuals may have a mixed immune thrombocytopenia syndrome; careful analysis of the mechanism of thrombocytopenia, especially in recurrent episodes and in patients who respond incompletely to PEX for TTP, is important when deciding whether to initiate or continue PEX, or to consider therapies appropriate for other mechanisms of thrombocytopenia.

Background The COVID‐19 pandemic has placed additional stressors on physician lives. In this study, we report findings from a survey conducted among attending physician (AP) members of the American Society for Apheresis (ASFA) to elucidate the status of their well‐being during the COVID‐19 pandemic as well as resources provided or actions taken by their institutions and themselves personally to maintain or improve their well‐being. Study Design and Methods A 17‐question, voluntary, IRB‐approved survey regarding well‐being was distributed to the ASFA AP members between August 26, 2020 and September 16, 2020. The descriptive analyses were reported as number and frequency of respondents for each question. Non‐parametric chi‐square tests, ANOVA, and paired t‐tests were performed to determine differences in categorical variables, changes in well‐being scores, and compare time points, respectively. Results Based on the responses of 70 attending level physicians representing the United States (U.S., 53, 75.7%) and outside the U.S. (17, 24.3%), the following were observed: (1) COVID‐19 negatively affects the well‐being of a sub‐population of APs, (2) neither institutional nor individual measures to improve well‐being completely resolved the problem of decreased AP well‐being during the pandemic, and (3) personal actions may be superior to institutional resources. Conclusion There is a widespread decline in AP well‐being during the COVID‐19 pandemic that was not adequately improved by institutional or personal resources/actions taken. Institutions and physicians must work together to implement strategies including resources and actions that could further improve AP physician well‐being during a public health crisis.
