Abstract
Refractory chronic immune thrombocytopenia (r-cITP) is one of the most challenging situations in chronic immune thrombocytopenia (cITP). Pediatric r-cITP is inconsistently defined in literature, contributing to the scarcity of data. Moreover, no evidence is available to guide the choice of treatment. We compared seven definitions of r-cITP including five pediatric definitions in 886 patients with cITP (median [min-max] follow-up 5.3 [1.0-29.3] years). The pediatric definitions identified overlapping groups of various sizes (4%-20%) but with similar characteristics (higher proportion of immunopathological manifestations [IM] and systemic lupus erythematosus [SLE]), suggesting that they adequately captured the population of interest. Based on the 79 patients with r-cITP (median follow-up 3.1 [0-18.2] years) according to the CEREVANCE definition (≥3 second-line treatments), we showed that r-cITP occurred at a rate of 1.15% new patients per year and did not plateau over time. In multivariate analysis, older age was associated with r-cITP. One patient (1%) experienced two grade five bleeding events after meeting r-cITP criteria and while not receiving second-line treatment. The cumulative incidence of continuous complete remission (CCR) at 2 years after r-cITP diagnosis was 9%. In this analysis, splenectomy was associated with a higher cumulative incidence of CCR (hazard ratio: 5.43, 95% confidence interval: 1.48-19.84, p = 7.8 × 10-4). In sum, children with cITP may be diagnosed with r-cITP at any time point of the follow-up and are at increased risk of IM and SLE. Second-line treatments seem to be effective for preventing grade 5 bleeding. Splenectomy may be considered to achieve CCR.

Abstract
The management of immune thrombocytopenia (ITP) and the prediction of patient response to therapy still represent a significant and constant challenge in hematology. ITP is a heterogeneous disease with an unpredictable evolution. Although the pathogenesis of ITP is currently better known and its etiology has been extensively studied, up to 75% of adult patients with ITP may develop chronicity, which represents a significant burden on patients' quality of life. A major risk of ITP is bleeding, but knowledge on the exact relationship between the degree of thrombocytopenia and bleeding symptoms, especially at a lower platelet count, is lacking. The actual management of ITP is based on immune suppression (corticosteroids and intravenous immunoglobulins), or the use of thrombopoietin receptor agonists (TPO-RAs), rituximab, or spleen tyrosine kinase (Syk) inhibitors. A better understanding of the underlying pathology has facilitated the development of a number of new targeted therapies (Bruton's tyrosine kinase inhibitors, neonatal Fc receptors, strategies targeting B and plasma cells, strategies targeting T cells, complement inhibitors, and newer TPO-RAs for improving megakaryopoiesis), which seem to be highly effective and well tolerated and result in a significant improvement in patients' quality of life. The disadvantage is that there is a lack of knowledge of the predictive factors of response to treatments, which would help in the development of an optimized treatment algorithm for selected patients.

Abstract
Rare but critical bleeding events in primary immune thrombocytopenia (ITP) present life-threatening complications in patients with ITP, which severely affect their prognosis, quality of life, and treatment decisions. Although several studies have investigated the risk factors related to critical bleeding in ITP, large sample size data, consistent definitions, large-scale multicenter findings, and prediction models for critical bleeding events in patients with ITP are unavailable. For the first time, in this study, we applied the newly proposed critical ITP bleeding criteria by the International Society on Thrombosis and Hemostasis for large sample size data and developed the first machine learning (ML)-based online application for predict critical ITP bleeding. In this research, we developed and externally tested an ML-based model for determining the risk of critical bleeding events in patients with ITP using large multicenter data across China. Retrospective data from 8 medical centers across the country were obtained for model development and prospectively tested in 39 medical centers across the country over a year. This system exhibited good predictive capabilities for training, validation, and test datasets. This convenient web-based tool based on a novel algorithm can rapidly identify the bleeding risk profile of patients with ITP and facilitate clinical decision-making and reduce the occurrence of adversities.

Abstract
Pediatric chronic immune thrombocytopenia (cITP) is a heterogeneous condition in terms of bleeding severity, second-line treatment use, association with clinical and/or biological immunopathological manifestations (IMs), and progression to systemic lupus erythematosus (SLE). No risk factors for these outcomes are known. Specifically, whether age at ITP diagnosis, sex, or IMs impact cITP outcomes is unknown. We report the outcomes of patients with pediatric cITP from the French nationwide prospective cohort OBS'CEREVANCE. We used multivariate analyses to investigate the effect of age at ITP diagnosis, sex, and IMs on cITP outcomes. We included 886 patients with a median (min-max) follow-up duration of 5.3 (1.0-29.3) years. We identified an age cutoff that dichotomized the risk of the outcomes and defined two risk groups: patients with ITP diagnosed <10 years (children) and ≥ 10 years (adolescents). Adolescents had a two to four-fold higher risk of grade ≥3 bleeding, second-line treatment use, clinical and biological IMs, and SLE diagnosis. Moreover, female sex and biological IMs were independently associated with higher risks of biological IMs and SLE diagnosis, second-line treatment use, and SLE diagnosis, respectively. The combination of these three risk factors defined outcome-specific risk groups. Finally, we showed that patients clustered in mild and severe phenotypes, more frequent in children and adolescents, respectively. In conclusion, we identified that age at ITP diagnosis, sex, and biological IMs impacted the long-term outcomes of pediatric cITP. We defined risk groups for each outcome, which will help clinical management and further studies.

Long-term efficacy and safety profile of splenectomy for pediatric chronic immune thrombocytopenia. Int J Hematol 2023; 117:774-780. [PMID: 36622550 DOI: 10.1007/s12185-022-03529-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 12/27/2022] [Accepted: 12/27/2022] [Indexed: 01/10/2023]
Abstract
There are few reports of the long-term efficacy of splenectomy in children with immune thrombocytopenia (ITP). In a 33-year period, we performed splenectomies in 23 pediatric patients with ITP at a single institution in Japan. The age at surgery was 5-22 years with a median of 10 years. The follow-up period was 1-141 months with a median of 48 months. Before surgery, we confirmed the presence or absence of the accessory spleen by contrast-enhanced CT scan and we recommended vaccination with pneumococcal vaccine. Four patients underwent laparotomy before 1998, and 19 patients underwent laparoscopic surgery after 1999. Splenectomy showed high efficacy with a partial response rate of 83% and a complete response rate of 74%. Complete response was maintained in 70% of patients until the end of the observation period, and 91% were able to discontinue long-term management drugs such as steroids. No serious complications such as infectious diseases were observed. Although the number of cases here was small, the long-term efficacy and safety of splenectomy makes it a viable option in pediatric ITP despite the existence of newer therapeutic agents. Further research is necessary to compare the long-term efficacy and safety of splenectomy with new therapeutic agents.

An Update on Pediatric Immune Thrombocytopenia (ITP): Differentiating Primary ITP, IPD, and PID. Blood 2021; 140:542-555.

Abstract
Immune thrombocytopenia (ITP) is the most common acquired thrombocytopenia in children and is caused by both immune-mediated decreased platelet production and increased platelet destruction. In the absence of a diagnostic test, ITP must be differentiated from other thrombocytopenic disorders, including inherited platelet disorders (IPD). In addition, a diagnosis of secondary ITP due to a primary immune deficiency (PID) with immune dysregulation may not be apparent at diagnosis but can alter management and should be considered in an expanding number of clinical scenarios. The diagnostic evaluation of children with thrombocytopenia will vary based on the clinical history and laboratory features. Access to genotyping has broadened the ability to specify the etiology of thrombocytopenia, while increasing access to immunophenotyping, functional immunologic and platelet assays, and biochemical markers has allowed for more in-depth evaluation of patients. With this greater availability of testing, diagnostic algorithms in patients with thrombocytopenia have become complex. In this article, we highlight the diagnostic evaluation of thrombocytopenia in children with a focus on ITP, including consideration of underlying genetic and immune disorders, and utilize hypothetical patient cases to describe disease manifestations and strategies for treatment of pediatric ITP.

Abstract
Immune thrombocytopenia (ITP) is a disease of heterogenous origin characterized by low platelet counts and an increased bleeding tendency. Three disease phases have been described: newly diagnosed (≤ 3 months after diagnosis), persistent (> 3-12 months after diagnosis), and chronic (> 12 months after diagnosis). The majority of children with ITP have short-lived disease and will not need treatment. For children with newly diagnosed ITP, who have increased bleeding symptoms, short courses of steroids are recommended. In children who do not respond to first-line treatment or who become steroid dependent, thrombopoietin receptor agonists (TPO-RAs) are recommended because of their efficacy and safety profiles. In this narrative review, we evaluate the available evidence on the use of the TPO-RA romiplostim to treat children with newly diagnosed or persistent ITP and identify data from five clinical trials, five real-world studies, and a case report. While the data are more limited for children with newly diagnosed ITP than for persistent ITP, the collective body of evidence suggests that romiplostim is efficacious in increasing platelet counts in children with newly diagnosed or persistent ITP and may result in long-lasting treatment-free responses in some patients. Furthermore, romiplostim was found to be well tolerated in the identified studies. Collectively, the data suggest that earlier treatment with romiplostim may help children to avoid the side effects associated with corticosteroid use and reduce the need for subsequent treatment.

Incidence and outcomes of refractory immune thrombocytopenic purpura in children: a retrospective study in a single institution. Sci Rep 2021; 11:14263.

Abstract
Treatment of children with refractory immune thrombocytopenic purpura (ITP) is challenging and poorly established. We retrospectively reviewed the clinical data of 87 patients under the age of 16 years who were diagnosed with ITP from April 1998 to March 2017 in our institution. Refractory ITP was defined as a platelet count of < 50 × 109/L at 14 days after receiving intravenous immunoglobulin (IVIG) and prednisolone. We presumed that there was a pathophysiological overlap between refractory ITP and refractory thrombocytopenia (RT): a subtype of refractory cytopenia of childhood (RCC). Immunosuppressive therapies including anti-thymocyte globulin and cyclosporine (CsA) have been adopted for children with RCC in Japan. Thus, from 2009 onwards, we changed the diagnosis from refractory ITP to RT and introduced CsA for refractory ITP/RT. Nine of 42 patients developed refractory ITP in the 1998–2008 group, who received conventional treatments such as IVIG and steroid therapy. Eight of 45 patients developed refractory ITP in the 2009–2017 group, who received CsA with or without IVIG therapy. The response rate at three years after diagnosis was significantly higher in the 2009–2017 group (98%) than in the 1998–2008 group (83%) (p = 0.019). In conclusion, our strategy of introducing CsA for refractory ITP/RT contributed to better outcomes.

Abstract
Incidence of intracranial hemorrhage (ICH) among children with primary immune thrombocytopenia (ITP) varies among different studies. We published data during the period of 1997-2007 of ICH in children with primary ITP, addressing risk factors and outcome. The aim of this study is to assess changes in incidence, risk factors, and outcome of ICH in children with ITP from last decade and to report the overall 20 years' experience. We compared 2008-2018 with the decade before it. Data of children with ITP and ICH during study period and ITP control cases were analyzed. Neurosurgical intervention and outcome were also reported. A total of 4340 children with primary ITP were evaluated. Twenty-five (0.63%) ICH events were reported over 2 decades. Head trauma, hematuria, and platelet counts < 10 × 109/L were the risk factors mostly associated with ICH. Overall mortality was 24%, and a further 28% had neurologic sequelae. Neurosurgical intervention was done in 12% of cases with good outcome.Conclusion: Persistent platelet counts < 10 × 109/L were a significant risk factor for ICH in both time periods, while head trauma and hematuria were more reported in the period of 2008-2018 as significant risk factors for ICH. Outcome was comparable in both periods. What is Known: • ICH is a rare complication of ITP; however, early recognition of risk factors and aggressive treatment might lead to complete recovery without sequalae. Platelet counts less than < 10 × 109/L are the main risk factor for ICH. Few studies reported other significant risk factors. What is New: • Hematuria and head trauma are significant risk factors for ICH in ITP, in addition to having a persistently low platelet count < 10 × 109/L. (more than 90 days in chronic ITP, 45 days in persistent and 21 days in acute ITP) • Combined treatment with IVIG and HDMP followed by platelet transfusion was associated with complete recovery without sequelae in almost 50% of patients.

Abstract
Our objective was to analyze if there was a significant relationship between platelet parameters (PLT, MPV, PDW, P-LCR, PCT) among dengue, its serological subgroups and controls. Serologically proven adult patients with dengue {(n = 238) (NS1 positive = 218, IgM positive = 14, NS1 & IgM positive = 6)} and age- and gender-matched controls (n = 254) were included. The MPV, PDW and P-LCR were significantly higher, and PLT and PCT were significantly lower in cases compared with controls. Cases as well as controls showed a positive correlation between PLT and PCT, both parameters individually showed negative correlation with MPV, PDW, P-LCR. MPV, PDW and P-LCR showed positive correlation with each other. The results were similar in the serological subgroups. Comparison of our results with other studies points toward an overall hyperdestructive etiology for thrombocytopenia in dengue. There were two subgroups of cases based on the severity of thrombocytopenia. The mean/median value of all the platelet parameters was lesser in the ≤20k group than the >20k group, except for PDW, which was high although not statistically significant. Suppression of megakaryopoiesis with concomitant immune destruction of platelets in severe dengue could explain low MPV and P-LCR with a high PDW in view of the presence of microthrombocytes as a result of immune destruction. Although an overall hyperdestructive mechanism contributes to thrombocytopenia in dengue, regular monitoring of the platelet indices could reflect the status of megakaryopoiesis and thrombokinetic axis, thus aiding easy determination of pathophysiology and treatment.

Abstract
Immune thrombocytopenia (ITP) is a potential presentation of COVID-19. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral testing should be considered in these patients to allow for appropriate hospital triaging and isolation to limit community spread and health care worker infection during epidemics or pandemics. ITP is characterized by isolated thrombocytopenia. Approximately two-thirds of children with primary ITP have a history of a viral infection during the previous month.1,2 Viruses commonly identified as triggers include cytomegalovirus, hepatitis C, herpes, varicella zoster, Epstein-Barr, influenza, and HIV.3-7 In this case report, we describe the first documented case of a pediatric patient with ITP who tested positive for SARS-CoV-2. This case raises awareness of ITP as a possible pediatric presentation of coronavirus disease.

Abstract
Intracranial hemorrhage (ICH) is a devastating complication of immune thrombocytopenia (ITP). However, information on ICH in ITP patients under the age of 60 years is limited, and no predictive tools are available in clinical practice. A total of 93 adult patients with ITP who developed ICH before 60 years of age were retrospectively identified from 2005 to 2019 by 27 centers in China. For each case, 2 controls matched by the time of ITP diagnosis and the duration of ITP were provided by the same center. Multivariate analysis identified head trauma (OR = 3.216, 95%CI 1.296-7.979, P =.012), a platelet count ≤ 15,000/μL at the time of ITP diagnosis (OR = 1.679, 95%CI 1.044-2.698, P =.032) and severe/life-threatening bleeding (severe bleeding vs. mild bleeding, OR = 1.910, 95%CI 1.088-3.353, P =.024; life-threatening bleeding vs. mild bleeding, OR = 2.620, 95%CI 1.360-5.051, P =.004) as independent risk factors for ICH. Intraparenchymal hemorrhage (OR = 5.191, 95%CI 1.717-15.692, P =.004) and a history of severe bleeding (OR = 4.322, 95%CI 1.532-12.198, P =.006) were associated with the 30-day outcome of ICH. These findings may facilitate ICH risk stratification and outcome prediction in patients with ITP.

Abstract
Childhood chronic immune thrombocytopenic purpura (cITP) is a rare disease. In severe cases, there is no evidence for the optimal therapeutic strategy. Our aim was to describe the real-life management of non-selected children with cITP at diagnosis. Since 2004, patients less than 18 years old with cITP have been enrolled in the national prospective cohort, OBS'CEREVANCE. From 1990 to 2014, in 29 centres, 392 children were diagnosed with cITP. With a median follow-up of six years (2·0-25), 45% did not need second-line therapy, and 55% (n = 217) received one or more second lines, mainly splenectomy (n = 108), hydroxychloroquine (n = 61), rituximab (n = 61) or azathioprine (n = 40). The overall five-year further second-line treatment-free survival was 56% [95% CI 49·5-64.1]. The use of splenectomy significantly decreased over time. Hydroxychloroquine was administered to children with positive antinuclear antibodies, more frequently older and girls, and reached 55% efficacy. None of the patients died. Ten years after the initial diagnosis, 55% of the 56 followed children had achieved complete remission. Children with cITP do not need second-line treatments in 45% of cases. Basing the treatment decision on the pathophysiological pathways is challenging, as illustrated by ITP patients with positive antinuclear antibodies treated with hydroxychloroquine.

Abstract
The impact of chronic immune thrombocytopenic purpura (ITP) on the psychological health and quality of life is evident among children and adolescents. We aimed to describe psychological disorders and assess quality of life in children with chronic ITP and compared their results with their healthy peers. A cross-sectional comparative study was carried out in a tertiary care university-affiliated hospital during a period from November, 2015 till April, 2018. We enrolled 119 children with chronic ITP and compared with 220 healthy peers. Relevant demographic and clinical data were collected and statistically analyzed. Quality of life for both patients and control groups was measured using pediatric quality of life inventory version 4 (Arabic one). Also psychiatric evaluation of both groups was done using Arabic version of Mini-International Neuropsychiatric Interview for Children (Mini-KID). Majority of patients (90.7%) exhibited mucocutaneous bleeding. Most of patients (61.3%) did not need any definitive treatment for chronic ITP while 38.6% received second line therapy. About one-third of the patients needed rescue medications to control active bleeding. The scores of all sub-scales of Peds QL 4.0 were significantly decreased among patients group when compared to their healthy peers (P < 0.001). General anxiety disorder and oppositional defiant disorders were the commonest psychiatric disorders among children with chronic ITP. Quality of life in children with chronic ITP is markedly impaired with occurrence of a variable spectrum of psychiatric disorders among the studied patients.

Long-term treatment with romiplostim and treatment-free platelet responses in children with chronic immune thrombocytopenia. Haematologica 2019; 104:2283-2291. [PMID: 30846500 PMCID: PMC6821612 DOI: 10.3324/haematol.2018.202283] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Accepted: 03/06/2019] [Indexed: 01/19/2023] Open
Abstract
Children with immune thrombocytopenia for ≥6 months completing a romiplostim study received weekly subcutaneous romiplostim (1-10 μg/kg targeting platelet counts of 50-200×109/L) in this extension to examine romiplostim’s long-term safety and efficacy. Sixty-five children received romiplostim for a median of 2.6 years (range: 0.1-7.0 years). Median baseline age was 11 years (range: 3-18 years) and platelet count was 28×109/L (range: 2-458×109/L). No patient discontinued treatment for an adverse event. Median average weekly dose was 4.8 mg/kg (range: 0.1-10 mg/kg); median platelet counts remained >50×109/L, starting at week 2. Nearly all patients (94%) had ≥1 platelet response (≥50×109/L, no rescue medication in the previous 4 weeks), 72% had responded at ≥75% of visits, and 58% had responded at ≥90% of visits. Treatment-free response (platelets ≥50×109/L ≥24 weeks without immune thrombocytopenia treatment) was seen in 15 of 65 patients while withholding romiplostim doses. At onset of treatment-free response, the nine girls and six boys had a median immune thrombocytopenia duration of four years (range: 1-12 years) and had received romiplostim for two years (range: 1-6 years). At last observation, treatment-free responses lasted for a median of one year (range: 0.4-2.1 years), with 14 of 15 patients still in treatment-free response. Younger age at first dose and platelet count >200×109/L in the first four weeks were associated with treatment-free responses. In this 7-year open-label extension, three-quarters of the patients responded ≥75% of the time, and romiplostim was well tolerated, with no substantial treatment-related adverse events. Importantly, 23% of children maintained treatment-free platelet responses while withholding romiplostim and all other immune thrombocytopenia medications for ≥6 months.

Abstract
BACKGROUND Conventional or homeopathic treatment of chronic immune thrombocytopenic purpura (ITP) is often difficult. The use of homeopathic dilutions of patient blood (HPB) for immunomodulation has been described, which inspired us to try the method in an ITP case. CASE REPORT A 2-year-old girl with chronic ITP was treated with homeopathic dilutions of her own capillary blood, given orally over 5 months. Immediately after treatment onset there was a rapid normalization of the thrombocyte counts. Within 6 weeks, they rose from 15,000/µl to 254,000/µl. After treatment stop, they decreased to 155,000/µl, increased again spontaneously to 270,000/µl and remained within normal range for over 3 years. CONCLUSIONS Oral administration of homeopathic dilutions of capillary patient blood may possibly be an effective treatment in chronic ITP. If our results can be reproduced, this will revolutionize the treatment of ITP.

Abstract
BACKGROUND Immune thrombocytopenia (ITP) during childhood spontaneously remits in up to 80% of children. Predictors of remission are not well understood. PROCEDURE We analyzed data from Intercontinental Cooperative ITP Study Group (ICIS) Registry II, a large prospective cohort of children with ITP, to investigate factors that might predict remission. RESULTS In ICIS Registry II, 705 patients had data collected through 12 months following diagnosis, with 383 patients having data available at 24 months as well. Younger age and pharmacologic treatment at diagnosis were significantly associated with disease resolution at 12 and 24 months (P < 0.0001 for both) as was bleeding at diagnosis (P < 0.0001 and P = 0.0213, respectively). Gender and platelet count at diagnosis were not significantly correlated with remission. In the multivariable analysis, remission at 12 months was associated with younger age, higher bleeding grade at diagnosis, and treatment with a combination of intravenous immunoglobulin (IVIG) and corticosteroids at diagnosis. Only younger age and treatment with IVIG and steroids in combination at diagnosis were associated with remission at 24 months. Patients <1 year of age had the highest odds of achieving remission at both 12 months (OR 4.7, 95% CI: 2.0-10.6) and 24 months (OR 7.0, 95% CI: 2.3-20.8). CONCLUSIONS Younger age, bleeding severity at diagnosis, and initial treatment with a combination of corticosteroids and IVIG are associated with remission at 12 months in the ICIS Registry II. Patients <1 year of age have the highest likelihood of remission. The relationship of bleeding and treatment at diagnosis requires further study to clarify whether these are independent predictors of remission.

Abstract
BACKGROUND There is limited information on long-term follow-up and prognostic factors for remission among children diagnosed with chronic immune thrombocytopenia (ITP). The aim of this study was to determine clinical outcomes and factors influencing remission in childhood chronic ITP. STUDY DESIGN The hospital records of children aged 0-15 years diagnosed with chronic ITP were retrospectively reviewed. Kaplan-Meier curves were fit to estimate the median time to complete remission with 95% confidence intervals (CIs). Multivariate Cox proportional hazards regression models were used to identify independent factors for remission. RESULTS A total of 113 patients were included in the analysis. The number of children achieving complete remission was 49 (46%) and the median time to remission was 7.1 years (95% CI: 4.8-11.0). The remission rates at 3, 5, 10, and 20 years were 25, 43, 60, and 75%, respectively. Factors influencing remission were platelets >60 × 109 /L at the onset of chronic ITP (hazard ratio [HR]: 7.24, 95% CI: 3.0-17.5) and treatment with intravenous immunoglobulin (HR: 0.37, 95% CI: 0.16-0.84). Age, gender, and clinical factors at the time of newly diagnosed ITP including bleeding manifestations, onset of symptoms, and history of preceding infection and vaccination were not predictive of remission. CONCLUSION The spontaneous complete remission rates of chronic ITP were 43 and 60% at 5 and 10 years, respectively, and reached 75% at 20 years. A higher platelet level at diagnosis of chronic ITP and form of treatment were statistically significant indicators for achieving complete remission.

Abstract
Inherited thrombocytopenia is a topic that was expanded greatly over the last decade and many new genes are being identified. However, inheritance patterns are not always easy to identify because sporadic cases from de novo mutations may in fact be more common. Few studies have assessed the relationship between thrombocytopenia and malignancies, specifically acute lymphoblastic leukemia (ALL). Here we present a pediatric case of persistent thrombocytopenia associated with T-cell ALL. Our patient was initially diagnosed with immune thrombocytopenic purpura with no evidence of malignancy on bone marrow biopsy but presented shortly after with ALL.

Abstract
Evidence-based medicine is growing in immune thrombocytopenia (ITP), but solid clinical data are still lacking in many areas. A majority of children has self-limited ITP, but chronic symptomatic ITP exists also in pediatrics. Management includes a watch-and-wait strategy for children with newly diagnosed ITP and no or mild bleeding, and immunoglobulins and corticosteroids, if more bleeding and mucous membrane involvement is present. Treatment endpoints differ in clinical research and in clinical practice. The requirement of platelet enhancing drugs needs to be better defined in guidelines. Second-line therapies for children are rarely required and include thrombopoietin-receptor agonists, rituximab, dexamethasone and immunosuppressants. Thrombopoietin-receptor agonists are successful in adult but also in pediatric ITP. The strategical position of splenectomy differs from that in adults. Although effective in children it is less frequently used because of its life-long cumulative risk of infectious diseases and a higher potential of spontaneous remission in ITP, providing a strong argument to defer splenectomy. The rarity of ITP makes clinical research expensive.

Abstract
PURPOSE This study examined the outcomes of children with chronic immune thrombocytopenia (ITP). MATERIALS AND METHODS We retrospectively analyzed the medical records of all patients diagnosed with ITP from January 1992 to December 2011 at our institution. RESULTS A total of 128 patients (64%) satisfied the criteria for newly diagnosed ITP, 31 (15%) for persistent ITP, and 41 (21%) for chronic ITP. The median age at diagnosis was 4.5 years (range, 1 month to 18 years). The median platelet count at diagnosis was 32×10⁹/L. A comparison of the initial treatment data from 2001 to 2011 with those from 1992 to 2000 showed that the number of bone marrow examinations decreased, whereas observation increased. Chronic ITP presented at an older age than newly diagnosed and persistent ITP (6.6 years vs. 3.8 years vs. 4.1 years, respectively); however, the difference did not reach statistical significance (p=0.17). The probability of complete remission of chronic ITP was 50% and 76% at 2 and 5 years after diagnosis, respectively. Patients aged <1 year at diagnosis had a significantly better prognosis than did older patients (hazard ratio, 3.86; p=0.02). CONCLUSION Children with chronic ITP showed a high remission rate after long-term follow-up. This study suggests that invasive treatments such as splenectomy in children with chronic ITP can be delayed for 4 to 5 years if thrombocytopenia and therapeutic medication do not affect the quality of life.

Abstract
Abstract
Bleeding manifestations in patients with immune thrombocytopenia (ITP) range from mild skin bruises to life-threatening intracranial hemorrhage (ICH). Severe bleeding is distinctly uncommon when the platelet count is >30 × 109/L and usually only occurs when the platelet count falls <10 × 109/L. Based on estimates from clinical studies, ITP registries and administrative databases, the frequency of ICH in patients with ITP is ∼0.5% in children and 1.5% in adults. Estimates of severe (non-ICH) bleeding are difficult to obtain because of the lack of standardized case definitions; the lack of a universally accepted, ITP-specific bleeding assessment tool; and the omission of reporting bleeding outcomes in many clinical studies. In practice, the presence of bleeding should dictate whether or not treatment is needed because many patients, especially children, can be safely managed with observation alone. Guiding principles for the management of ITP, based on the bleeding risk are: (1) Decide when treatment is needed and when it can safely be withheld; (2) for patients with chronic ITP, use the least toxic treatment at the lowest dose; (3) emergency treatment of severe thrombocytopenia-associated bleeding requires combination therapy; and (4) early aggressive therapy may result in durable platelet count responses.

Abstract
OBJECTIVE To explore the clinical utility of measuring platelet-associated immunoglobulin (PAIG) at the time of diagnosis in children with immune thrombocytopenia (ITP). METHODS PAIG was measured by flow cytometry using fluorescent murine anti-IgG and anti-IgM. In a cohort of 88 children with ITP, the assay was performed within 15 days of diagnosis and before any treatment in 68 cases. We reviewed the results and examined the relation of isotype profile and degree of elevation to clinical manifestations and course of disease. RESULTS PAIG was elevated in 74%, with raised IgM being more frequent than IgG (63% vs. 44%, P = 0.04) and with isotype profile depending on symptom onset. Platelet counts at presentation were similar in all subgroups, but mucosal bleeding was less frequent in PAIG-negative patients compared to the positive groups (5.5% vs. 34%, P = 0.03). Duration of thrombocytopenia was similar in negative and positive cases, but during follow-up, significant bleeding events occurred less frequently in PAIG-negative patients (0% vs. 14%, P = 0.18). CONCLUSION Approximately one-quarter of children are PAIG-negative, and these children have milder bleeding tendency at diagnosis and lower morbidity during follow-up. Raised PAIG possibly may cause some degree of platelet dysfunction.

Abstract
PURPOSE The purpose of this study was to determine the frequency of CD4(+)CD25(+)FoxP3(+) regulatory T cells (Treg) in the peripheral blood of patients with childhood chronic immune thrombocytopenic purpura (ITP) exhibiting thrombocytopenia and spontaneous remission. The findings of this study indicate the possibility of predicting spontaneous recovery and pathogenesis of childhood chronic ITP. METHODS Eleven children with chronic ITP (seven thrombocytopenic and four spontaneous remission cases; mean age, 8.8 years; range, 1.7-14.9 years) were enrolled in this study. Five healthy children and eight healthy adults were included as controls. The frequency of Treg was evaluated by flow cytometry in the peripheral blood. RESULTS In this study, four patients (36%) achieved spontaneous remission within 2.8 years (mean year; range, 1.0-4.4 years). The frequency of Treg was significantly lower in patients with persisting thrombocytopenia (0.13%±0.09%, P<0.05), than that in the patients with spontaneous remission (0.30%±0.02%), healthy adults controls (0.55%±0.44%), and healthy children controls (0.46%±0.26%). A significantly positive correlation was found between the frequency of Treg and the platelet count in children. CONCLUSION These data suggest that a lower frequency of Treg contributes to the breakdown of self-tolerance, and may form the basis for future development of specific immunomodulatory therapies. Furthermore, Treg frequency has prognostic implication toward the natural course and long-term outcomes of childhood chronic ITP.

Abstract
BACKGROUND The burden of severe bleeding in adults and children with immune thrombocytopenia (ITP) has not been established. OBJECTIVES To describe the frequency and severity of bleeding events in patients with ITP, and the methods used to measure bleeding in ITP studies. PATIENTS/METHODS We performed a systematic review of all prospective ITP studies that enrolled 20 or more patients. Two reviewers searched Medline, Embase, CINAHL and the Cochrane registry up to May 2014. Overall weighted proportions were estimated using a random effects model. Measurement properties of bleeding assessment tools were evaluated. RESULTS We identified 118 studies that reported bleeding (n = 10 908 patients). Weighted proportions for intracerebral hemorrhage (ICH) were 1.4% for adults (95% confidence interval [CI], 0.9-2.1%) and 0.4% for children (95% CI, 0.2-0.7%; P < 0.01), most of whom had chronic ITP. The weighted proportion for severe (non-ICH) bleeding was 9.6% for adults (95% CI, 4.1-17.1%) and 20.2% for children (95% CI, 10.0-32.9%; P < 0.01) with newly-diagnosed or chronic ITP. Methods of reporting and definitions of severe bleeding were highly variable in primary studies. Two bleeding assessment tools (Buchanan 2002 for children; Page 2007 for adults) demonstrated adequate inter-rater reliability and validity in independent assessments. CONCLUSIONS ICH was more common in adults and tended to occur during chronic ITP; other severe bleeds were more common in children and occurred at all stages of disease. Reporting of non-ICH bleeding was variable across studies. Further attention to ITP-specific bleeding measurement in clinical trials is needed to improve standardization of this important outcome for patients.

Abstract
Immune thrombocytopaenic purpura (ITP) is an autoimmune systemic disease detectable by the presence of low blood platelets count (<10(5)/µl) and the production of autoantibodies against glycoproteins expressed on the platelet surface. The clinical course is often acute, and life-threatening events may occur especially in children, with 52% of paediatric patients recovering either spontaneously or after treatment. A chronic ITP evolution is observed in 64% of adults, of whom 12% will develop an overlapping autoimmune disease. Several microbial agents such as CagA-positive Helicobacter pylori or Candida albicans and a number of viruses including CMV, EBV or HIV can potentially trigger ITP through molecular mimicry. Moreover, ITP improves after treatment of the underlying infection. Similarly, vaccines such as MMR may prompt ITP (IRR 5.48, 1.61-18.64, p < 0.006). Early recognition of the underlying microbial trigger and the removal of modifiable aetiopathogenetic factors should be integrated as a complementary treatment strategy in all patients who do not readily improve with standard ITP care.

Abstract
BACKGROUND The immune thrombocytopenia (ITP) criteria were newly standardized by the International Working Group. Thus, we analyzed the natural course of childhood chronic ITP to predict the prognosis based on the revised criteria. METHODS The medical records of children with chronic ITP from May 2000 to February 2013 in our institute were reviewed. RESULTS Forty-seven children with chronic ITP who were not undergoing corticosteroid therapy were included. Their initial platelet count was 23±25×10(9)/L, and age at diagnosis was 6.3±4.1 years. The follow-up period was 5.4±3.7 years. Among them, 44.7% (21/47) showed spontaneous remission and maintained a platelet count ≥100×10(9)/L. And 66.0% (31/47) maintained a platelet count ≥50×10(9)/L until the last follow-up date. The time periods required for the platelet count to be maintained ≥50×10(9)/L and ≥100 ×10(9)/L were 3.1±2.7 and 3.6±2.7 years. Age at diagnosis in the ≥50×10(9)/L group (5.7±4.4 years) was significantly lower than the age at diagnosis in the <50×10(9)/L group (7.4±3.3 years) (P=0.040). And follow-up period was the factor influencing prognosis between the ≥100×10(9)/L group and <50×10(9)/L group (P=0.022). CONCLUSION Approximately 45% of children with chronic ITP recovered spontaneously about 3-4 years after the diagnosis and 2/3 of patients maintained a platelet count ≥50×10(9)/L, relatively safe state. Age at diagnosis of ITP and follow-up period were the factors influencing prognosis in this study.

Abstract
Long-term follow-up of children with immune thrombocytopenia (ITP) indicates that the majority undergo remission and severe thrombocytopenia is infrequent. Details regarding bleeding manifestations, however, remain poorly categorized. We report here long-term data from the Intercontinental Cooperative ITP Study Group Registry II focusing on natural history, bleeding manifestations, and management. Data on 1345 subjects were collected at diagnosis and at 28 days, 6, 12, and 24 months thereafter. Median platelet counts were 214 × 10(9)/L (interquartile range [IQR] 227, range 1-748), 211 × 10(9)/L (IQR 192, range 1-594), and 215 × 10(9)/L (IQR 198, range 1-598) at 6, 12, and 24 months, respectively, and a platelet count <20 × 10(9)/L was uncommon (7%, 7%, and 4%, respectively). Remission occurred in 37% of patients between 28 days and 6 months, 16% between 6 and 12 months, and 24% between 12 and 24 months. There were no reports of intracranial hemorrhage, and the most common site of bleeding was skin. In patients with severe thrombocytopenia we observed a trend toward more drug treatment with increasing number of bleeding sites. Our data support that ITP is a benign condition for most affected children and that major hemorrhage, even with prolonged severe thrombocytopenia, is rare.

Abstract
Spontaneous improvement (SI) occurs more frequently in children with chronic immune thrombocytopenia (cITP) than in adults. It is generally accepted that, with the exception of splenectomy, conventional medical approaches for cITP do not change the natural course of the disease. Previous studies on pediatric cITP have reported prognostic factors associated with SI; however, it is important to know when such improvement occurs to enable optimal treatment strategies for cITP. Here, we report results of retrospective analysis of 56 consecutive pediatric patients with cITP at our institution. The median follow-up period after ITP diagnosis was 67 months (11-185 months). Of the 44 patients without splenectomy, 17 achieved SI at a median age of 8.5 years (2.3-16.5 years). The estimated incidence of SI was 24.6 ± 6.0 % at 36 months. In 16 of the 17 patients with SI, the recovery was achieved within 18 months from diagnosis, or at an age of less than 10 years, whereas among the 24 who did not achieve spontaneous improvement both at "an age of 10 years or more" and at "18 months or more from ITP diagnosis", only one recovered spontaneously. A treatment decision tree, including the indication for splenectomy, should be considered based on this watershed point.
