Abstract
Immune thrombocytopenia (ITP) is an autoimmune disease typically associated with severely depleted platelet counts. However, additional symptoms (e.g. increased fatigue and memory/concentration difficulties) can profoundly impact patients' quality of life. The nature and severity of cognitive impairment in ITP, and potential association with patient/disease characteristics were evaluated in 49 adults with relapsed/refractory ITP. The Cogstate Brief Battery quantitatively assessed psychomotor function (DET), attention (IDN), visual learning (OCL) and working memory (ONB) individually, as well as DET/IDN and OCL/ONB composites. Clinically important cognitive impairment (defined as z-score ≤ -1) for ≥2 individual tests was observed in 29 patients (59%). Impairment was highest for IDN (67% of patients), followed by DET (53%), ONB (39%) and OCL (16%). A higher magnitude of impairment was observed for the DET/IDN composite (mean z-score -1.54; 95% CI, -1.94 to -1.13) than OCL/ONB (mean z-score -0.21; 95% CI, -0.49 to 0.07). The severity of cognitive impairment was comparable to mild traumatic brain injury and associated with increasing age and fatigue but unrelated to platelet count or corticosteroid use. Overall, these results warrant a clinical need to further consider the potential of cognitive dysfunction in assessing ITP patients.

Abstract
The treatment of immune thrombocytopenia (ITP) is challenging and treatment outcomes depend on numerous unknown and patient-specific factors. Corticosteroids are the cornerstone of ITP treatment, but they are associated with many side effects. In this retrospective cohort study, treatment outcomes and treatment adherence in patients with ITP were investigated in 214 ITP patients from November 15, 2022 to March 15, 2023. Multinomial regression analysis models were used to identify predictive factors for treatment outcomes. A p value of less than 0.05 was considered statistically significant. Most study participants were female 161 (75.5%), and the majority 172 (80.4%) of them were taking prednisolone only. In terms of treatment adherence, 178 (83.2%) of the study participants adhered well to their ITP medications. The complete response rate at 3 months was 139 (65.0%). Predictive factors for partial response were increased negative impact of ITP on health-related quality of life (AOR = 1.221, 95% CI 1.096-1.360), being treated at Tikur Abessa Sepcialazed Hospital (AOR = 0.431, 95% CI 0.197-0.941) and the presence of heavy menstrual bleeding (AOR = 2.255, 95% CI 0.925-5.497) compared to patients with complete response. Hepatitis B virus-infected ITP patients (AOR = 0.052, 95% CI 0.004-0.621) were also a predictive factor for no response compared to complete response.

Abstract
Immune thrombocytopenia (ITP) is an autoimmune disease characterized by an isolated decrease in the platelet count and an increased risk of bleeding. The pathogenesis is complex, affecting multiple components of the immune system and causing both peripheral destruction of platelets and impaired central megakaryopoiesis and platelet production in the bone marrow. Here, we intend to contextualize the current knowledge on the pathophysiology, terminology, epidemiology, clinical manifestations, diagnosis, and prognosis of ITP from a historical perspective and the first references to the never-stopping garnering of knowledge about this entity. We highlight the necessity to better understand ITP in order to be able to provide ITP patients with personalized treatment options, improving disease prognosis and reducing the incidence or frequency of refractoriness.

Abstract
Background Immune thrombocytopenia (ITP) is characterized by primarily autoantibody-mediated platelet destruction and impaired platelet production resulting in thrombocytopenia and an increased risk of bleeding. Other manifestations include increased risk of thrombosis and diminished quality of life. Current treatment approaches are directed toward lowering the rate of platelet destruction or stimulating platelet production to prevent bleeding. Rilzabrutinib is an oral, reversible, potent Bruton tyrosine kinase inhibitor that was specifically designed to treat immune-mediated diseases and mediates its therapeutic effect through a dual mechanism of action: (1) inhibiting B-cell activation and (2) interrupting antibody-coated cell phagocytosis by Fc gamma receptor in spleen and liver. A 24-week dose-finding phase I/II study of rilzabrutinib in patients with ITP showed a 40% platelet response (⩾2 consecutive platelet counts of ⩾50 × 109/L and increase from baseline ⩾20 × 109/L without rescue medication use) and a well-tolerated safety profile with only grade 1/2 transient adverse events across dose levels. Objectives Assess the efficacy and safety of oral rilzabrutinib in adult and adolescent patients with persistent or chronic ITP. Design Rilzabrutinib 400 mg BID is being evaluated in the ongoing LUNA 3 multicenter, double-blind, placebo-controlled phase III study. Methods and analysis The primary endpoint is durable platelet response, defined as achieving platelet counts of ⩾50 × 109/L for at least two-thirds of ⩾8 available weekly scheduled platelet measurements during the last 12 weeks (including ⩾2 available measurements within the last 6 weeks) of the 24-week blinded treatment period in the absence of rescue therapy. Ethics Ethical guidelines and informed consent are followed. Discussion The LUNA 3 trial will further investigate rilzabrutinib's safety and efficacy in adult and adolescent patients, with the primary goal of addressing a major objective in treating patients with ITP: durability of platelet response.

Abstract
It is known that patients with immune thrombocytopenia (ITP) have fatigue and impairment of health-related quality of life (HRQoL). However, it is hypothesized that patients with refractory ITP have additional burdens that should be considered. Specifically, fatigue is more pronounced in patients with refractory disease, there are additional side effects from second- and third-line treatments, additional anxiety about the long-term course of the disease, impairment in HRQoL resulting from heavy menstrual bleeding and concerns related to family planning. The burden of disease, therefore, should be carefully assessed and considered in these patients. However, researchers have utilized numerous tools for evaluating HRQoL and fatigue, making comparison of data across studies challenging. There is a need to standardize assessment using either disease-specific or generic instruments that can be easily implemented in routine clinical practice. Additionally, whether treatment of low platelet count and bleeding symptoms will have a positive influence on HRQoL remains to be seen and published evidence is conflicting. Nevertheless, improvement of HRQoL is a major treatment goal for both patients and physicians and should be especially considered when treating patients with refractory ITP.

Abstract
INTRODUCTION Immune thrombocytopenia (ITP) is a rare chronic disease, frequently accompanied by fatigue, which is an important comorbidity associated with this disease. Patients experience difficulties in managing their daily activities and a reduction in their overall quality of life (QoL). The causes of fatigue in ITP are not clarified yet, and underlying causes seem to be multifactorial. The development of fatigue may not solely be influenced by a decrease in platelet count but also by unknown factors as well as psychological reasons. METHODS This prospective, multicenter, exploratory, pilot study aimed to investigate which parameters contribute to the occurrence of fatigue in patients with ITP. Adult patients with ITP and with or without fatigue who visited the study center for their regular appointments were asked to complete questionnaires pertaining to patient-reported outcome measures regarding bleeding symptoms, depression, sleep apnea, and hypersomnia. Blood tests included platelet count as well as different parameters like vitamin D. RESULTS A total of 36 patients (100%; 27 females (75%) and nine males (25%)) with primary ITP, with a median age of 46.5 years (range 19‑83 years) were analyzed. The median duration of ITP was 4.5 years (min‑max 0-21). Approximately one-third of patients (29.4%; 10/34 patients) had no comorbidities. The two most frequently used current treatment options were "watch-and-wait" (38.9%; 14/36 patients) and "avatrombopag" (30.6%; 11/36 patients); eight patients (22.2%; 8/36 patients) needed rescue therapy with corticosteroids. There was a statistically negative correlation between fatigue and year of diagnosis (r=-0.41, p=0.014). Results indicated no statistically significant relationship between fatigue and age or differences in fatigue between the genders. Ferritin predicted fatigue with statistical significance. Platelet count was not correlated with the level of fatigue. A significant correlation was obvious between fatigue, depression, and obstructive sleep apnea syndrome (OSAS) as well as sleep-related problems (p<0.01). DISCUSSION Patient characteristics were comparable to that of other studies. The level of fatigue negatively impacts the lives of patients with ITP. Age and gender were not correlated with fatigue in ITP, which is in line with other reports. Interestingly, the fatigue level was higher in patients presenting with additional depression and poor sleeping quality due to, e.g., hypersomnia, which seems common. Fatigue levels seem independent from thrombocyte levels, which were reported elsewhere. CONCLUSION Patients diagnosed with ITP several years ago cope with their condition better than patients with a more recent diagnosis, who have higher levels of fatigue. Concurrent depression, hypersomnia, and sleep apnea are important underestimated factors, which do have a negative effect on the QoL of patients with ITP. We were able to show that patients with ITP might face an unmet medical need in terms of delayed diagnosis and supportive therapy. To our knowledge, this is the first report on combined findings of depression, hypersomnia, and sleep apnea in patients with ITP.

Abstract
BACKGROUND There is lacking studies of longitudinally assessment of fatigue and health-related quality of life (HRQoL) among Chinese immune thrombocytopenia (ITP) adults. We aimed to evaluate changes in fatigue and HRQoL and identify the associated factors. METHODS Patients' characteristics, Functional Assessment of Chronic Illness Therapy (FACIT-F) and the ITP-specific Patient Assessment Questionnaire (ITP-PAQ) scores at admission (T0), at discharge (T1), and three months after discharge (T2) were collected. Linear mixed effects models were used to examine changes over time. RESULTS We included 175 patients. The mean score of FACIT-F at T0 was 37.2 and increased at T1 (39.0), while then decreased at T2 (34.7). Patients who were single, retired, had persistent ITP, splenomegaly had more severe fatigue, whereas those who had not received any prior treatment and had a bleeding score of 0 at admission had milder fatigue. The mean score of ITP-PAQ was 57.7 at T0, then gradually increased to 60.3 at T1 and 62.8 at T2. Patients with persistent ITP and those who have never received treatment for ITP have better HRQoL. CONCLUSION ITP adults' fatigue and HRQoL were impaired. Patients' fatigue improved at discharge but worsened at three months after discharge, while HRQoL gradually improved over time.

Abstract
BACKGROUND Few studies have investigated long-term survival in patients with primary immune thrombocytopenia (pITP). Further, changes in prognosis over the past decades and prognosis of secondary immune thrombocytopenia (sITP) are largely unstudied. Our objectives were to study comorbidity-adjusted prognostic changes and causes of death in chronic pITP and sITP patients. STUDY DESIGN/METHODS Using nationwide Danish health registries 1980-2016, we identified 1762 patients with chronic pITP (median age 58 (IQR, 37-73) years) and 128 with chronic sITP (median age 59 (IQR, 40-73) years). Patients were age-sex-matched to 74,781 general population comparators. Comorbidity was assessed using Charlson Comorbidity Index (CCI). RESULTS Overall median survival was reduced by 5.1 years (95% CI, 0.7-9.4) (p < .001) for pITP and 11.1 years (95% CI, 5.8-16.4) (p < .001) for sITP. 5-year survival increased from 69% (95% CI, 59-78) in 1980-89 to 80% (95% CI, 75-83) in 2010-16 for pITP, and decreased from 100% (95% CI, 89-98) to 64% (95% CI, 87-91) for sITP. However, numbers were small for sITP. 5-year survival for pITP with high CCI was 41% (95% CI, 32-49), and 85% (95% CI, 83-87) for low CCI. Bleeding, infection and hematological cancer were relatively frequent causes of death with adjusted subhazard ratios of 3.25 (95% CI, 2.33-4.52), 1.53 (95% CI, 1.08-2.16) and 2.16 (95% CI, 1.12-4.16) in pITP respectively, and 10.52 (95% CI, 1.43-77.36) for hematological cancer in sITP. CONCLUSIONS Long-term survival is reduced in chronic ITP but seems to be improving. Comorbidity and sITP are associated with a poor prognosis.

Abstract
Data describing physicians' and patients' perspectives towards immune thrombocytopenia (ITP) management and impact of disease in Iran are limited. This ITP World Impact Survey was conducted between October 2019 and October 2020. Of the 114 patients included in the survey, 17 were aged ≤18 years. Forty-seven physicians, including 22 pediatric hematologists, participated in the survey. Fatigue and anxiety around stable platelet counts were frequent patient-reported symptoms at diagnosis and at survey completion. According to physicians, "watch-and-wait" was the preferred treatment option for mean (standard deviation) proportion of 50.1 (24.1) and 48.6 (21.8) of their adult and pediatric patients, respectively, following first diagnosis. Per adult and pediatric hematologists, the most prescribed treatments for newly diagnosed patients based on available answers were steroids (100%, n = 20/20; 89%, n = 16/18), respectively. Forty percent of adult (n = 10/25) and 38% of pediatric hematologists (n = 8/21) reported that ITP reduced patients' quality of life. Energy levels (46%, n = 52/112) and ability to concentrate on everyday activities (42%, n = 47/113) were the most affected aspects of patients' lives. This I-WISh study in Iran underlined the negative impact of ITP on patients.

Abstract
Primary immune thrombocytopenia (ITP) is an acquired autoimmune disorder characterized by isolated thrombocytopenia. Most patients with ITP have antiplatelet antibodies of the immunoglobulin G (IgG) subtype which through interaction with platelet and megakaryocyte glycoproteins result in increased platelet destruction and inhibition of platelet production. There are a variety of therapeutic options available for the treatment of ITP including corticosteroids, IVIgG, TPO-RA, rituximab, fostamatinib, and splenectomy. Long-term remissions with any of these therapies can vary widely and patients may require additional therapy. The neonatal Fc receptor (FcRn) plays a pivotal role in IgG and albumin physiology through recycling pathways. Efgartigimod is a human IgG1-derived fragment that has been modified by ABDEG technology to increase its affinity for FcRn at both physiologic and acidic pH. The binding of efgartigimod to FcRn blocks the interaction of IgG with FcRn facilitating increased lysosomal degradation of IgG and decreasing total IgG levels. Based on the mechanism of action and the known pathophysiology of ITP as well as the efficacy of other therapies such as intravenous immunoglobulin (IVIG), the use of efgartigimod in patients with ITP is attractive. This article will briefly discuss the pathophysiology of ITP, current treatments, and the data available on efgartigimod in ITP.

Abstract
Background Fatigue in immune thrombocytopenia (ITP) is frequent and burdensome, but we lack the knowledge to help these patients.
Aim The aim of the study is to explore the role of disease activity and other potentially modifiable factors in fatigue.
Method This cross-sectional study included adult chronic ITP patients (n = 59). Univariable linear regression (corrected for confounders) was used to determine the relationship between disease activity (platelet count <30 × 109/L or treatment), disease-specific factors (bleeding symptoms, ferritin), and transdiagnostic factors (FACT-G physical/functional/emotional/social well-being subscales, physical activity level, and vitamin D) and fatigue (Checklist Individual Strength fatigue subscale). Several multivariable models with clustered sets of variables were used to compare the proportion of explained variance of fatigue (adjusted R
2).
Results Significant relations with moderate effect sizes (>0.50) were found for physical and functional well-being and fatigue, and physical activity and fatigue. Other significant relations with fatigue (effect size 0.30–0.47) included skin and organ bleeding, emotional and social well-being, vitamin D, and disease activity. Notably, the models with disease activity and disease-specific factors explained <20% of the variance in fatigue, while the models with transdiagnostic factors (functioning and physical activity) explained >50%. Vitamin D alone explained 12% of the variance in fatigue.
Conclusion Transdiagnostic (non-disease-specific) rather than disease-specific factors explained a large part of the variance in ITP-related fatigue. Many factors related to fatigue are potentially modifiable and should be investigated as targets for interventions.

Thrombopoietin receptor agonist discontinuation rates and reasons among patients with immune thrombocytopenia: a study of administrative claims linked with medical chart review. Ann Hematol 2022; 101:1915-1924.

Abstract
Administrative claims provide a rich data source for retrospective studies of real-world clinical practice, yet some important data may be inconsistent or unavailable. This study explored factors influencing discontinuation of thrombopoietin receptor agonists (TPO-RAs) among patients with immune thrombocytopenia (ITP), by adding medical chart abstraction for additional details. Adult (≥ 18 years) patients with continuous commercial or Medicare Advantage with Part D health insurance coverage were included. Inclusion criteria were ≥ 1 claim for eltrombopag or romiplostim and ≥ 2 diagnoses of ITP between December 31, 2017, and January 1, 2020. Providers were asked to provide access to medical charts for abstraction. The analyses included only patients who discontinued TPO-RA and described patient characteristics, treatment patterns, platelet values, and reasons for discontinuation. Among 207 ITP patients treated with a TPO-RA, 137 (66%) discontinued treatment during the observation period. The mean TPO-RA treatment duration was 185 days. Mean platelet count at the time of discontinuation was 197 × 109/L. The most common reason for discontinuation was improvement of the patient's condition (42%). Other reasons included worsening of ITP/lack of response (12%), adverse events (12%), and cost-related or social reasons (23%). No reason was reported for 10%. Notably 26% of patients who discontinued remained off all ITP therapy for the remainder of the study, with a mean treatment-free period of 262 days. These results emphasize that some patients with ITP are able to discontinue TPO-RA therapy and achieve durable treatment-free periods.

Abstract
INTRODUCTION Primary immune thrombocytopenia (ITP) is an autoimmune disorder characterized by a low platelet count (<100 × 109/L) with an increased risk of bleeding. Recent (2019) guidelines from the International Consensus Report (ICR) expert panel and the American Society of Hematology (ASH) provide updated recommendations for the diagnosis and management of ITP. AREAS COVERED The 2019 ICR and ASH guidelines are reviewed, and differences and similarities highlighted. Clinical approaches to the treatment of ITP are discussed, including the role of fostamatinib which is an approved treatment option in adult patients who are refractory to other treatments. EXPERT OPINION The 2019 ICR and ASH guidelines reflect recent changes in the management of ITP. Current treatment approaches for ITP are more rational and evidence-based than in the past. Patients should be treated based on their needs rather than on disease stage, and patient-specific outcomes, (e.g. quality of life) should be considered. Whilst corticosteroids are the mainstay of initial ITP treatment their use should be limited. For subsequent treatment, the use of thrombopoietin receptor agonist (TPO-RA) agents, fostamatinib and rituximab in adults is supported by robust evidence. Rituximab and recently approved fostamatinib offer viable alternatives to splenectomy.

Abstract
BACKGROUND Immune thrombocytopenia is a rare autoimmune disorder with associated bleeding risk and fatigue. Recommended first-line treatment for immune thrombocytopenia is high-dose glucocorticoids, but side effects, variable responses, and high relapse rates are serious drawbacks. METHODS In this multicenter, open-label, randomized, controlled trial conducted in the United Kingdom, we assigned adult patients with immune thrombocytopenia, in a 1:1 ratio, to first-line treatment with a glucocorticoid only (standard care) or combined glucocorticoid and mycophenolate mofetil. The primary efficacy outcome was treatment failure, defined as a platelet count of less than 30×109 per liter and initiation of a second-line treatment, assessed in a time-to-event analysis. Secondary outcomes were response rates, side effects, occurrence of bleeding, patient-reported quality-of-life measures, and serious adverse events. RESULTS A total of 120 patients with immune thrombocytopenia underwent randomization (52.4% male; mean age, 54 years [range 17 to 87]; mean platelet level, 7×109 per liter) and were followed for up to 2 years after beginning trial treatment. The mycophenolate mofetil group had fewer treatment failures than the glucocorticoid-only group (22% [13 of 59 patients] vs. 44% [27 of 61 patients]; hazard ratio, 0.41; range, 0.21 to 0.80; P = 0.008) and greater response (91.5% of patients having platelet counts greater than 100×109 per liter vs. 63.9%; P<0.001). We found no evidence of a difference between the groups in the occurrence of bleeding, rescue treatments, or treatment side effects, including infection. However, patients in the mycophenolate mofetil group reported worse quality-of-life outcomes regarding physical function and fatigue than those in the glucocorticoid-only group. CONCLUSIONS The addition of mycophenolate mofetil to a glucocorticoid for first-line treatment of immune thrombocytopenia resulted in greater response and a lower risk of refractory or relapsed immune thrombocytopenia, but with somewhat decreased quality of life.

Abstract
INTRODUCTION The management of ITP has in recent years been transformed from reliance on immunosuppressants and splenectomy to targeted therapy with thrombopoietin receptor agonists (TPO-RA) that directly stimulate platelet production in the bone marrow. This has reduced the long-term infective complications and toxicities associated with the use of potent immunosuppressants and splenectomy. The welltolerated romiplostim, itself a novel drug construct called peptibody, has established itself, alongside other TPO-RA as the preferred 2nd line therapy in major international guidelines on treatment of ITP. AREAS COVERED This review summarizes the data from early licensing trials of romiplostim and discusses the real-world experience to date, the unexpected emerging data on treatment-free long-term remission achieved using TPO-RA, and the case for its early introduction in the therapeutic pathway. The emerging risk of thrombosis is also discussed. EXPERT OPINION The use of romiplostim and other TPO-RA will be increasingly brought forward in the management pathway of ITP with the prospect of modifying the long-term outcome of the disease by increasing sustained treatment-free remission. With the prospect of several new targeted therapies been introduced into clinical practice, TPO-RA will likely be a key component of future combination therapies for difficult cases.

Abstract
Corticosteroids remain a crucial component of first-line therapy for immune thrombocytopenia (ITP) due to low cost, high initial response rates, and acceptable short-term tolerability. However, extended and recurrent use of corticosteroids is associated with substantial toxicity. Survey studies indicate that >95% of patients with ITP treated with corticosteroids report adverse effects, more than one-third of whom require reduction or discontinuation of treatment. In light of the heavy treatment burden of prolonged corticosteroid exposure, clinical practice guidelines recommend limiting corticosteroid treatment to no more than 6 weeks in adults with ITP receiving initial therapy. For patients who require subsequent therapy, clinical practice guidelines recommend treatments more suitable for long-term disease control such as thrombopoietin receptor agonists, rituximab, other immune-modulating medications, or splenectomy, rather than repeated courses of corticosteroids. Despite these recommendations, real-world evidence suggests that corticosteroids remain the most frequently used treatment for adults with ITP, not only in the first line, but also in the second and third line. In this review, we summarize evidence on the efficacy, safety, and tolerability of corticosteroids; discuss the problem of overuse; and suggest strategies for curtailing the excessive use of corticosteroids in adults with ITP.

To date, few studies have explored fatigue and its relationship with chronic ITP in pediatric age. The aim of the present multicentric pilot study is to determine fatigue perception in a large group of children with chronic ITP and their caregivers using the PedsQL Multidimensional Fatigue Scale (PedsQL MFS), and to compare the results with those of healthy control subjects. PROCEDURE Children with chronic ITP aged 5-18 years and/or caregivers of children aged 2-18 years were enrolled. Child/adolescent self-report was used for patients aged 5-18 years, and parent proxy-report for patients aged 2-18 years. The questionnaire was offered as online survey. PedsQL MFS is composed of 18 items covering three dimensions: General Fatigue Scale, Sleep/Rest Fatigue Scale, and Cognitive Fatigue Scale. RESULTS One hundred ninety-one patients affected by chronic ITP and 248 caregivers answered the PedsQL MFS. We have highlighted that lower values of PedsQL MFS scores are obtained in the 13-18 age group. Moreover, sleep/rest fatigue domain appears to be more compromised in all age groups. For all PedsQL MFS scores, pediatric patients with chronic ITP and their caregivers reported statistically significant worse fatigue than healthy children. CONCLUSIONS This study suggests that fatigue is relevant among children and adolescents affected by chronic ITP. The PedsQL MFS represents an adequate instrument for measuring fatigue in patients with chronic ITP. Therefore, symptoms of fatigue should be routinely assessed in clinical practice.

Abstract
Immune thrombocytopenia (ITP) is an autoimmune disorder defined by a significantly reduced number of platelets in blood circulation. Due to low levels of platelets, ITP is associated with frequent bruising and bleeding. Current evidence suggests that low platelet counts in ITP are the result of multiple factors, including impaired thrombopoiesis and variations in immune response leading to platelet destruction during pathological conditions. Patient outcomes as well as clinic presentation of the disease have largely been shown to be case-specific, hinting towards ITP rather being a group of clinical conditions sharing common symptoms. The most frequent characteristics include dysfunction in primary haemostasis and loss of immune tolerance towards platelet as well as megakaryocyte antigens. This heterogeneity in patient population and characteristics make it challenging for the clinicians to choose appropriate therapeutic regimen. Therefore, it is vital to understand the pathomechanisms behind the disease and to consider various factors including patient age, platelet count levels, co-morbidities and patient preferences before initiating therapy. This review summarizes recent developments in the pathophysiology of ITP and provides a comprehensive overview of current therapeutic strategies as well as potential future drugs for the management of ITP.

Abstract
Immune thrombocytopenia (ITP) has a substantial, multifaceted impact on patients' health-related quality of life (HRQoL). Data describing which aspects of ITP physicians and patients perceive as having the greatest impact are limited. The ITP World Impact Survey (I-WISh) was a cross-sectional survey, including 1507 patients and 472 physicians, to establish the impact of ITP on HRQoL and productivity from patient and physician perspectives. Patients reported that ITP reduced their energy levels (85% of patients), capacity to exercise (77%), and limited their ability to perform daily tasks (75%). Eighty percent of physicians reported that ITP symptoms reduced patient HRQoL, with 66% reporting ITP-related fatigue substantially reduced patient HRQoL. Patients believed ITP had a substantial impact on emotional well-being (49%) and 63% worried their condition would worsen. Because of ITP, 49% of patients had already reduced, or seriously considered reducing their working hours, and 29% had considered terminating their employment. Thirty-six percent of patients employed at the time of the survey felt ITP decreased their work productivity, while 51% of patients with high/very high symptom burden reported that ITP affected their productivity. Note, I-WISh demonstrated substantive impact of ITP on patients' HRQoL both directly for patients and from the viewpoint of their physicians. Patients reported reduced energy levels, expressed fears their condition might worsen, and those who worked experienced reduced productivity. Physicians should be aware not only of platelet counts and bleeding but also the multi-dimensional impact of ITP on patients' lives as an integral component of disease management.

Abstract
Primary immune thrombocytopenia (ITP) is an acquired autoimmune disorder characterized by isolated thrombocytopenia caused by increased platelet destruction and impaired platelet production. First-line therapies include corticosteroids, intravenous immunoglobulin, and anti-D immunoglobulin. For patients who are refractory to these therapies, those who become corticosteroid dependent, or relapse following treatment with corticosteroid, options include splenectomy, rituximab, and thrombopoietin-receptor agonists, alongside a variety of additional immunosuppressive and experimental therapies. Despite recent advances in the management of ITP, many areas need further research. Although it is recognized that an assessment of patient-reported outcomes in ITP is valuable to understand and guide treatment, these measures are not routinely measured in the clinical setting. Consequently, although corticosteroids are first-line therapies for both children and adults, there are no data to suggest that corticosteroids improve health-related quality of life or other patient-related outcomes in either children or adults. In fact, long courses of corticosteroids, in either children or adults, may have a negative impact on a patient's health-related quality of life, secondary to the impact on sleep disturbance, weight gain, and mental health. In adults, additional therapies may be needed to treat overt hemorrhage, but unfortunately the results are transient for the majority of patients. Therefore, there is a need to recognize the limitations of current existing therapies and evaluate new approaches, such as individualized treatment based on the probability of response and the size of effect on the patient's most bothersome symptoms and risk of adverse effects or complications. Finally, a validated screening tool that identifies clinically significant patient-reported outcomes in routine clinical practice would help both patients and physicians to effectively follow a patient's health beyond simply treating the laboratory findings and physical symptoms of ITP. The goal of this narrative review is to discuss management of newly diagnosed and refractory patients with ITP, with a focus on the limitations of current therapies from the patient's perspective.

Abstract
INTRODUCTION Immune thrombocytopenia (ITP) durably affects quality of life in patients. Patient education aims at improving their self-care and psychosocial skills, allowing them be more autonomous, to prevent avoidable complications, and to maintain or improve quality of life. The aim of this study was to assess patients' and caregivers' expectations regarding patient education in ITP. METHOD ITP Patients and caregivers were asked about topics that should be addressed in a patient education program through a digital anonymous survey. Their responses were analyzed both qualitatively and quantitatively. A double-blind keyword attribution of the answers was carried out by two physicians and then faced until consensus was found. RESULTS Thirty-eight ITP patients were included: 68% were less than 50 years old and 84% had chronic ITP. On the other hand, twenty-five caregivers were included. Caregivers raised more topics related to the cognitive domain than patients. The psychoaffective and motivational topics tended to be more represented in patients' responses. Only 53% of topics were mentioned by both patients and caregivers. CONCLUSION These discrepancies emphasize the differences between patients and caregivers' expectations regarding a patient education program in ITP, and thus the relevance of patient-caregiver co-construction of such programs.

Abstract
BACKGROUND Despite an increase in the number of therapies available to treat patients with immune thrombocytopenia (ITP), there are minimal data from randomized trials to assist physicians with the management of patients. OBJECTIVE These evidence-based guidelines of the American Society of Hematology (ASH) are intended to support patients, clinicians, and other health care professionals in their decisions about the management of ITP. METHODS In 2015, ASH formed a multidisciplinary guideline panel that included 8 adult clinical experts, 5 pediatric clinical experts, 2 methodologists with expertise in ITP, and 2 patient representatives. The panel was balanced to minimize potential bias from conflicts of interest. The panel reviewed the ASH 2011 guideline recommendations and prioritized questions. The panel used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, including evidence-to-decision frameworks, to appraise evidence (up to May 2017) and formulate recommendations. RESULTS The panel agreed on 21 recommendations covering management of ITP in adults and children with newly diagnosed, persistent, and chronic disease refractory to first-line therapy who have non-life-threatening bleeding. Management approaches included: observation, corticosteroids, IV immunoglobulin, anti-D immunoglobulin, rituximab, splenectomy, and thrombopoietin receptor agonists. CONCLUSIONS There was a lack of evidence to support strong recommendations for various management approaches. In general, strategies that avoided medication side effects were favored. A large focus was placed on shared decision-making, especially with regard to second-line therapy. Future research should apply standard corticosteroid-dosing regimens, report patient-reported outcomes, and include cost-analysis evaluations.

Abstract
While umbilical cord blood is increasingly utilized as a stem cell source, immune complications associated with the procedure have been recognized. These complications result from significant immune system dysregulation and defective reconstitution following transplant causing an imbalance between T-cell subsets, aberrant B cells, and abnormal antibody production. This may occur up to 12 months after transplant coinciding with thymic regeneration in adults. The aim of our review is to describe the incidence, pathophysiology, clinical features, and prognosis of autoimmune cytopenias following umbilical cord blood transplant. Furthermore, we review the treatment strategies reported in the existing literature, describe the authors' experience with the complication, and highlight novel treatment options being studied. The knowledge of the occurrence and timing of autoimmune complications of umbilical cord blood transplantation is essential for detection and treatment of the disease. Emerging therapeutic options include interleukin-2 (IL-2), which is also being studied for the treatment of acute and chronic graft-versus-host disease. IL-2 has favorable effects on growth, differentiation, and function of regulatory T cells. Monoclonal antibody treatments, such as daratumumab, are also on the forefront and more experience with them will guide further treatment strategies.

Abstract
Immune thrombocytopenia (ITP), an acquired autoimmune disorder of low platelets and risk of bleeding, has a substantial impact on health-related quality of life (HRQoL). Patients with ITP often report significant fatigue, although the pathophysiology of this is poorly understood. In this observational cohort of 120 children receiving second-line therapies for ITP, we assessed reports of fatigue using the Hockenberry Fatigue Scale. Children and adolescents with ITP reported a similarly high level of fatigue with 54% (29/54) of children and 62% (26/42) of adolescents reporting moderate-to-severe fatigue. There was no correlation between fatigue and age or gender. Adolescents with newly diagnosed and persistent ITP had higher mean fatigue scores than those with chronic ITP (P = 0·03). Fatigue significantly improved in children and adolescents by 1 month after starting second-line treatments, and this improvement continued to be present at 12 months after starting treatment. Fatigue scores at all time-points correlated with general HRQoL using the Kids ITP Tool, but did not correlate with bleeding symptoms, platelet count, or platelet response to treatment. Fatigue is common in children and adolescents with ITP and may benefit from ITP-directed treatment even in the absence of bleeding symptoms.

Abstract
Immune thrombocytopenia is an autoimmune hematological disorder characterized by severely decreased platelet count of peripheral cause: platelet destruction via antiplatelet antibodies which may also affect marrow megakaryocytes. Patients may present in critical situations, with cutaneous and/or mucous bleeding and possibly life-threatening organ hemorrhages (cerebral, digestive, etc.) Therefore, rapid diagnosis and therapeutic intervention are mandatory. Corticotherapy represents the first treatment option, but as in any autoimmune disorder, there is a high risk of relapse. Second line therapy options include: intravenous immunoglobulins, thrombopoietin receptor agonists, rituximab or immunosuppression, but their benefit is usually temporary. Moreover, the disease generally affects young people who need repeated and prolonged treatment and hospitalization and therefore, it is preferred to choose a long term effect therapy. Splenectomy - removal of the site of platelet destruction - represents an effective and stable treatment, with 70-80% response rate and low complications incidence. A challenging situation is the association of ITP with pregnancy, which further increases the risk due to the immunodeficiency of pregnancy, major dangers of bleeding, vital risks for mother and fetus, potential risks of medication, necessity of prompt intervention in the setting of specific obstetrical situations - delivery, pregnancy loss, obstetrical complications, etc. We present an updated review of the current clinical and laboratory data, as well as a detailed analysis of the available therapeutic options with their benefits and risks, and also particular associations (pregnancy, relapsed and refractory disease, emergency treatment).

Abstract
Childhood ITP is often considered to be a relatively mild haematological disorder, with only a minority of patients requiring treatment for troublesome bleeding. Over recent years, wider effects of the condition have been identified in some adults, particularly relating to fatigue and cognitive impairment. In this study, we sought to investigate such effects in a group of children with ITP and further our understanding of their psychological profile. Children attending routine haematology outpatient clinics and their parents were asked to complete standardised questionnaires designed to assess a range of psychological and cognitive factors. Although the majority of children had some scores within the normal range, a significantly high proportion had difficulties with fatigue (70·6%), emotional and behavioural symptoms (25·7%) or executive functioning (19·4%). Quality of life and subjective evaluation of the illness (appraisal) correlated significantly with each of these domains, but bleeding severity and platelet count did not. Our findings provide valuable insight into the broader impact of childhood ITP, which could aid in providing holistic care, potentially contribute to decisions regarding medical treatment, and guide future research.

Abstract
Over the last decade, there have been numerous developments and changes in treatment practices for the management of patients with immune thrombocytopenia (ITP). This article is an update of the International Consensus Report published in 2010. A critical review was performed to identify all relevant articles published between 2009 and 2018. An expert panel screened, reviewed, and graded the studies and formulated the updated consensus recommendations based on the new data. The final document provides consensus recommendations on the diagnosis and management of ITP in adults, during pregnancy, and in children, as well as quality-of-life considerations.

Abstract
To describe the health-related quality of life (HRQoL) and fatigue burden among adult patients with immune thrombocytopenia (ITP) in China and determine whether they vary with disease phase. This is a cross-sectional, multi-centre observational study of adult ITP patients and the general population. Participants completed the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). We compared HRQoL and fatigue between ITP patients and the general population, overall and by disease phase (newly diagnosed, persistent, and chronic), using propensity score matching. 203 Patients and 269 members of the general population were recruited. Thirty-six ITP patients (17.7%) were newly diagnosed, 46 (22.7%) were persistent, and 121 (59.6%) were chronic. Compared with the general population, ITP patients had impaired HRQoL and greater fatigue burden. The persistent ITP group showed the largest number of SF-36 scales exceeding the minimally important difference: physical functioning [- 10.5; 95% confidence interval (CI) - 24.5 to 3.5; P < 0.001], role physical (- 16.7; 95% CI - 36.4 to 3.0; P < 0.001), social functioning (- 15.6; 95% CI - 34.5 to 3.3; P < 0.001), and role emotional (- 12.1; 95% CI - 26.0 to 1.8; P < 0.001). Chronic ITP patients had the worst FACIT-F scores (36.89 ± 5.21). Higher fatigue severity was associated with lower physical and mental HRQoL. The HRQoL and fatigue burden of Chinese adult patients with ITP vary by disease phase. Persistent ITP patients were the most vulnerable subgroup in terms of HRQoL, while chronic ITP patients bear the heaviest fatigue burden.

Abstract
Immune thrombocytopenic purpura (ITP) is an autoimmune disorder characterised by low platelet counts and increased bleeding risk. In 2009, two cross-sectional studies determined that fatigue and cognitive impairment (CI) were common in ITP. Here, we report the results from a longitudinal study of 34 people with ITP. Fatigue severity remained unchanged over 7 years, and CI significantly improved. Future fatigue and CI severity could be predicted using baseline severity scores. These findings may be reassuring for ITP patients, as symptoms remain stable over time. Furthermore, using baseline scores to predict future severity could aid the clinical management of ITP.

Abstract
The thrombopoietin receptor agonists (TPO-RAs) are a class of platelet growth factors commonly used to treat immune thrombocytopenia (ITP). There are three agents that have been investigated for the treatment of chronic ITP: the peptide agent romiplostim and the small molecule agents eltrombopag and avatrombopag. These agents offer a higher clinical response rate than most other ITP therapies but may require indefinite use. This review is a critical appraisal of the TPO-RAs in adult ITP, defining the optimal patient groups to receive these agents and assisting the hematologist with agent choice, goals of treatment, dosing strategies, and toxicity management. Use of endogenous thrombopoietin levels to predict response to eltrombopag and romiplostim treatment is discussed and alternative dosing protocols suited for certain patient subgroups are described. Finally, indications for discontinuation and combination therapy with other agents are considered.

Abstract
Immune thrombocytopenia (ITP) is an immune-mediated disorder characterized by a reduced platelet count and patients may develop bruising or mucosal bleeding. Since 2003, generic health-related quality of life (HRQoL) measures have been applied and ITP-specific measures developed, alongside trials of novel therapeutic agents. These have identified significant morbidity in patients with ITP, including fatigue, fear of bleeding and a negative impact on role, social and work activities. This review critically evaluates HRQoL data in adults and children with ITP. It also considers the impact of treatment and how patient-reported outcomes might be applied to care to optimize patients' quality of life.

Abstract
Objective: To study the fatigue symptoms of adult patients with primary immune thrombocytopenia (ITP) and to analyze the possible factors that affect the severity of fatigue. Methods: Eligible adult patients with ITP who admitted to Institute of Hematology & Blood Diseases Hospital were enrolled in this study and the questionnaires including a Chinese version of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) , the Pittsburgh sleep quality index (PSQI) , the Hospital Anxiety and Depression scale (HADS) and demographic information were completed. The predictors of fatigue were determined with multiple linear regression analyses. Results: A total of 207 patients with ITP were enrolled, including 70 males (33.8%) and 137 females (66.2%) , the median age was 42 (18-72) years old. The FACIT-F score in ITP patients was (37.50±9.05) . The FACIT-F severity of ITP patients was positively correlated with the platelet count (r=0.307, P<0.001) . The FACIT-F severity was negatively correlated with bleeding severity (r=-0.276, P<0.001) , sleep quality (r=-0.654, P<0.001) , depression (r=-0.598, P<0.001) and anxiety (r=-0.616, P<0.001) . A multiple linear regression analysis revealed that the severity of ITP-related fatigue was significantly correlated with platelet count (P<0.001) , bleeding severity (P=0.004) , sleep quality (P<0.001) and depression (P<0.001) . Conclusion: Fatigue was determined by complicated factors in adult ITP patients. Interventions addressing depressive symptoms, sleep quality, bleeding symptoms and platelet count could be potential avenues for treatment of fatigue in patients with ITP.

Abstract
BACKGROUND The natural history and its modulation by treatments administered for immune thrombocytopenia (ITP) in the clinical practice remains unknown. In addition, little information is available on the characteristics and management of ITP in Spain. METHODS We conducted an observational, multicenter, registry in 70 Hematology Services from Spain between 2009 and 2011, which included children from 2 months of age and adults with primary ITP or another ITP diagnosed within the last 6 months (platelet count [PC] < 100 × 109/l). Patients were followed-up at 6 and 12 months. RESULTS 484 patients were included (median [Q1, Q3] age 52 [29,74] years, 87.6% adults), 56% women, 10.5% with secondary ITP. Median (Q1, Q3) PC at diagnosis was 12 × 109/l (4, 32); 72% of patients had bleeding symptoms (62% cutaneous bleeding, 29% oral cavity bleeding, 18% epistaxis). 81% of patients with primary ITP received first-line treatment, mainly with corticosteroids (>6 weeks in 59% of cases), either alone (41%) or associated with intravenous immunoglobulin (33%). The response (≥30 × 109/L) to first-line treatment was 92%. A total of 19% of patients received second-line treatment and 6% additional treatments. At 12 months, 74% of primary ITP patients maintained a PC ≥ 100 × 109/L in absence of treatment (10% still had hemorrhagic manifestations). CONCLUSIONS Characteristics of Spanish ITP patients are comparable to those from other countries. Although a high response rate to first-line treatments is observed, at 1 year, the disease persists in around one quarter of patients. Overall therapeutic management in Spain conforms to current recommendations, except for an excessive duration of corticosteroids therapy.

Abstract
Immune thrombocytopenia (ITP) is a complex autoimmune disease characterized by low platelet counts. The pathogenesis of ITP remains unclear although both antibody-mediated and/or T cell-mediated platelet destruction are key processes. In addition, impairment of T cells, cytokine imbalances, and the contribution of the bone marrow niche have now been recognized to be important. Treatment strategies are aimed at the restoration of platelet counts compatible with adequate hemostasis rather than achieving physiological platelet counts. The first line treatments focus on the inhibition of autoantibody production and platelet degradation, whereas second-line treatments include immunosuppressive drugs, such as Rituximab, and splenectomy. Finally, third-line treatments aim to stimulate platelet production by megakaryocytes. This review discusses the pathophysiology of ITP and how the different treatment modalities affect the pathogenic mechanisms.

Abstract
Immune thrombocytopenia (ITP) is a rare, acquired autoimmune condition characterized by a low platelet count and an increased risk of bleeding. Although many children and adults with ITP will not need therapy beyond historic first-line treatments of observation, steroids, intravenous immunoglobulin (IVIG), and anti-D globulin, others will have an indication for second-line treatment. Selecting a second-line therapy depends on the reason for treatment, which can vary from bleeding to implications for health-related quality of life (HRQoL) to likelihood of remission and patient preference with regard to adverse effects, route of administration, and cost. Published studies of these treatments are limited by lack of comparative trials, in addition to inconsistent outcome measures, definitions, and efficacy endpoints. This article provides an up-to-date comparison of the second-line treatments, highlighting important outcome measures including bleeding, HRQoL, fatigue, and platelet counts, which influence treatment selection in a shared decision-making model.

Abstract
BACKGROUND Dependent on the absence or presence of associated diseases, autoimmune thrombocytopenia (ITP) can be classified as primary or secondary form. The manifestation of the associated diseases is not temporally defined and may occur during observation. Thus the question which disease is the primary one remains unanswered. METHODS All 386 patients included in this study were treated by a single primary physician between 1996 and 2015 at the Charité Berlin and met current ITP criteria. Medical records and investigations were reviewed to assess diseases associated with ITP. RESULTS Initially, the vast majority of patients presented with primary ITP (isolated disease). Based on our findings, ITP was found to be associated with other abnormalities in most cases. These abnormalities included: positive direct antiglobulin test in 49 of 386 tested patients (13%), affections of the thyroid gland in 41 of 386 tested patients (11%), infections in 30 (8%), solid malignancies in 20 (5%) and hematological malignancies in 10 patients (3%), as well as many other miscellaneous diseases. Moreover, of 160 patients who did not receive prior intravenous immunoglobulin treatment, 40 (25%) showed antibody deficiency. CONCLUSION In conclusion, the incidence of 'true' ITP as a primary disease is less common than has yet been suggested. Additionally, there is evidence that ITP itself predispose affected subjects toward development of other diseases.

Abstract
The main objective of this study was to compare health-related quality of life (HRQOL) of primary immune thrombocytopenia (pITP) patients with that of general population, overall, and by patient group (i.e., newly diagnosed, persistent, and chronic patients). Fatigue was also investigated as a secondary objective. Overall, 424 adult patients were enrolled in a multicenter observational study and the control group consisted of a representative sample from the general population. Propensity score matching plus further multivariate linear regression adjustment was used to compare HRQOL outcomes between pITP patients and general population. Mean age of patients was 54 years. Of those with HRQOL assessment, 99 patients (23.6%) were newly diagnosed, 53 (12.6%) were persistent, and 268 (63.8%) were chronic pITP patients. Comparison by patient group versus their respective peers in the general population revealed greater impairments in persistent pITP patients. Persistent pITP patients reported clinically meaningful impairments in physical functioning (-15; 95% CI -24.1 to -5.8; P = 0.002), social functioning (-15.3; 95% CI -25.5 to -5.1; P = 0.004), role physical (-28.4; 95% CI -43.1 to -13.7; P < 0.001), role emotional (-23.9; 95% CI -40.1 to -7.7; P = 0.004), and mental health scales (-11.3; 95% CI -21.2 to -1.4; P = 0.026) of the SF-36 questionnaire. Higher fatigue severity was associated with lower physical and mental HRQOL outcomes. Our findings suggest that the burden of the disease and treatment might depend on the disease phase and that persistent pITP patients are the most vulnerable subgroup. Am. J.

Abstract
BACKGROUND Eltrombopag and romiplostim are thrombopoietin receptor agonists (TPOs) that have been increasingly used for the treatment of immune thrombocytopenia (ITP). Based on our experience, the incidence of abortive treatment with these drugs and the occurrence of adverse reactions that lead to therapy break-off despite response are higher than has been previously suggested. METHODS During the last 8 years, a total of 65 patients were treated with eltrombopag and/or romiplostim at our institute. RESULTS 36 of a total of 58 patients responded well to eltrombopag. In 12 patients that responded, treatment with eltrombopag was discontinued due to the development of adverse reactions. Eltrombopag was replaced by romiplostim in 23 cases (14 non-responders, 9 patients with adverse reactions). Of these patients, 83% responded to romiplostim. Among all patients treated with romiplostim (n = 32), 75% initially responded; however, 8 of these patients developed adverse reactions. Romiplostim was replaced by eltrombopag in 5 cases (4 due to adverse reactions, 1 non-responsive patient), and only 3 (60%) of these patients were observed to respond to eltrombopag. CONCLUSION TPOs often remain ineffective in ITP or result in adverse reactions, which lead to treatment stop or to drug switch. Therefore, alternative treatment options are required.

Abstract
Fatigue is an important aspect of health-related quality of life from the patient perspective and can have significant socio-economic consequences. It is a common feature of chronic illnesses and a significant number of both adults and children with immune thrombocytopenia (ITP) suffer from fatigue. Reliable, validated fatigue scales have been developed for use in ITP. These will facilitate future investigation of its pathogenesis and the effectiveness of intervention. Acute inflammation acts on neural and endocrine systems resulting in 'sickness behaviour', an adaptive response to infection and injury. Inflammation is also thought to cause fatigue in chronic disease and immune dysregulation in ITP appears to have a number of pro-inflammatory components. Clinicians should consider fatigue when assessing the burden of disease. Although effective ITP-directed therapy can improve fatigue, a number of fatigue-directed strategies may also need to be considered.

Abstract
Canine immune thrombocytopenia (ITP) is analogous to human ITP, with similar platelet counts and heterogeneity in bleeding phenotype among affected individuals. With a goal of ultimately investigating this bleeding heterogeneity, a canine model of antibody-mediated ITP was developed. Infusion of healthy dogs with 2F9, a murine IgG2a monoclonal antibody to the canine platelet glycoprotein GPIIb (a common target of autoantibodies in ITP) resulted in profound, dose-dependent thrombocytopenia. Model dogs developed variable bleeding phenotypes, e.g. petechiae and haematuria, despite similar degrees of thrombocytopenia. 2F9 infusion was not associated with systemic inflammation, consumptive coagulopathy, or impairment of platelet function. Unexpectedly however, evaluation of cytokine profiles led to the identification of platelets as a potential source of serum interleukin-8 (IL8) in dogs. This finding was confirmed in humans with ITP, suggesting that platelet IL8 may be a previously unrecognized modulator of platelet-neutrophil crosstalk. The utility of this model will allow future study of bleeding phenotypic heterogeneity including the role of neutrophils and endothelial cells in ITP.

Abstract
Introduction Treatment of the rare cases of patients with chronic idiopathic thrombocytopenic purpura with acute coronary syndrome can be a significant problem. The patient in our case report was treated successfully with percutaneous coronary intervention. Case presentation A 51-year-old man of Turkish origin who had idiopathic thrombocytopenic purpura was admitted to our hospital with severe chest pain. His electrocardiography was normal on admission but dynamic ischemic changes were observed during follow-up. He underwent immediate coronary angiography. In his angiography, left anterior descending artery stenosis was 90% together with the diagonal ostium. Percutaneous coronary intervention was performed successfully. Bleeding complications were not observed after the procedure. Conclusions We report the presence of a rare case of chronic idiopathic thrombocytopenic purpura in a patient with acute coronary syndrome. In this situation a serious multidisciplinary approach is required before coronary intervention.

Abstract
As the involvement of oxidative stress (OS) in autoimmune thrombocytopenia (AITP) has been reported, a fast and rapid test for the reliable measurement of OS and antioxidant capacities (AOCs) might be a useful tool in extending current diagnostic possibilities. The free oxygen radical test (FORT) and free oxygen radical defence (FORD) assay (Callegari, Italy) are easy to perform and reliable, with results available within 15 minutes. Thirty-seven AITP patients and 37 matched healthy individuals were included in this study. All participants responded to a standard questionnaire provided by these assays. Female patients with AITP were observed to demonstrate significantly higher OS in comparison to female controls (P = 0.0027) and male AITP patients (P = 0.0018). The AOCs were not reduced in patients with AITP (P = 0.7648). Correlation of OS with platelet count identified a weak positive correlation (P = 0.0327, Spearman R = 0.4672). The questionnaire revealed that ITP patients in comparison to healthy controls are more stressed, feel exhausted and fatigued, and eat a healthier diet. In conclusion, OS is predominant in female but not in male patients with AITP suggesting gender-specific differences in the pathomechanisms of AITP. Identification of patients with high levels of OS might be beneficial in the management of AITP.

Abstract
Immune thrombocytopenia (ITP) is a common hematologic disorder characterized by isolated thrombocytopenia. ITP presents as a primary or a secondary form. ITP may affect individuals of all ages, with peaks during childhood and in the elderly, in whom the age-specific incidence of ITP is greatest. Bleeding is the most common clinical manifestation of ITP. The pathogenesis of ITP is complex, involving alterations in humoral and cellular immunity. Corticosteroids remain the most common first line therapy for ITP. This article summarizes the classification and diagnosis of primary and secondary ITP, as well as the pathogenesis and options for treatment.

Abstract
The Intercontinental Cooperative immune thrombocytopenia (ITP) Study Group (ICIS) held its 4th Expert Meeting in September 2012 in Montreux, Switzerland. The program reunited researchers and clinicians from all over the globe and was organized with lectures and seminars for real-time exchange of latest information. Platelets target victims of autoimmune disease on their own, participating under physiological conditions in the immune network; these small cells are more immunologically savvy than previously thought. Currently, researchers focus their attention on regulatory T and regulatory B cells, ie, cells that might have a decisive impact on how ITP spontaneously resolves or evolves into chronic disease. Diagnostic criteria and prognosis are increasingly benefiting from molecular biological tests, and therapy has evolved with the availability of biosimilar agents and recombinant hormones or blockers of their receptors.

Abstract
BACKGROUND Symptoms in keeping with autonomic dysfunction are commonly described by primary Sjögrens syndrome patients (pSS); whether objective abnormalities of autonomic function occur is unclear. This study set out to explore dynamic cardiovascular autonomic responses in pSS and their relationship with symptoms and quality of life. METHODS Twenty-one people from the UK pSS registry, 21 community controls and 21 patients with the autoimmune liver disease primary biliary cirrhosis (PBC) (matched case-wise for age and sex) attended for assessment of autonomic responses to orthostasis and Valsalva manoeuvre (VM). pSS patients also completed EULAR Sjögrens Syndrome patient-reported index (ESSPRI), EULAR Sjögren's syndrome disease activity index (ESSDAI), fatigue impact scale and EURO-QOL 5-dimension (EQ-5D). RESULTS Compared with controls, pSS patients had significantly lower baseline systolic blood pressure (SBP) (114 ± 13 vs. 127 ± 20; P = 0.02), which dropped to a significantly lower value (98 ± 22 vs. 119 ± 24, P = 0.009). When area under the curve (AUC) was calculated for when the SBP was below baseline this was significantly greater in pSS compared to both control groups (pSS vs. control vs. PBC: 153 ± 236 vs. 92 ± 85 vs. 1.2 ± 0.3, P = 0.005). Peak phase IV SBP during the VM was significantly lower in pSS (P = 0.007) indicating early sympathetic failure. Increased heart rate associated with fatigue (P = 0.02; r(2) = 0.2) and EQ-5D. A shift in sympathetic-vagal balance associated with overall symptom burden (ESSPRI) (P = 0.04, r(2) = 0.3) and EULAR sicca score (P = 0.016; r(2) = 0.3), the latter also correlated with baroreceptor effectiveness (P = 0.03; r(2) = 0.2) and diastolic blood pressure variability (P = 0.003; r(2) = 0.4). CONCLUSION pSS patients have impaired blood pressure response to standing. Dysautonomia correlates with PSS-associated symptoms and quality of life.
