Abstract
Immune thrombocytopenia (ITP) is an autoimmune blood disorder characterised by isolated severe thrombocytopenia. Arterial thrombotic events, such as acute ischaemic stroke (AIS), are rare complications. A 56-year-old woman with chronic ITP on eltrombopag and dexamethasone therapy presented to the emergency department due to AIS in the vertebrobasilar territory, and lower abdominal pain. The computed tomography (CT) scan of the head was unremarkable, whereas CT angiography revealed left vertebral artery occlusion. As the platelet count was sufficient, intravenous thrombolysis (IVT) was initiated. However, after 15 min, an anaphylactic reaction occurred, which was appropriately solved. Although the IVT was prematurely stopped, the NIHSS score improved from 7 to 2, and the follow-up head CT scan remained unremarkable. CT angiography of the thoracoabdominal aorta revealed multiple thrombi in the infrarenal aorta, inferior mesenteric artery (IMA), and left renal artery. The abdominal pain subsided after IVT, but recurred within 24 h. Repeated CT angiography showed ischaemia of the descending colon, with persistent IMA occlusion. After the hemicolectomy condition stabilised. Discrete left-sided ataxia and impaired sensation were the only neurological sequelae. We found two articles reporting only three patients with ITP who suffered AIS and were treated with IVT. A favourable outcome was observed in two cases, while one patient suffered an intracranial haemorrhage (ICH) and died. A review of AIS cases with undefined thrombocytopenia treated with IVT reported ICH in up to 6.8% of patients. Our case suggests that IVT for AIS may be effective in patients with ITP. Further data are needed to better clarify this issue.

Ge J, Liu Y. Heat shock protein-70 is elevated in childhood primary immune thrombocytopenia. Eur J Med Res 2022; 27:244. [DOI: 10.1186/s40001-022-00868-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Accepted: 10/25/2022] [Indexed: 11/13/2022] Open
Abstract
Abstract
Background
Immune thrombocytopenia (ITP) is an acquired autoimmune disorder characterized by the destruction of the platelets resulting from autoimmune recognition and subsequent attack. Heat shock proteins (HSPs) are directly associated with progression and pathogenesis in some specific autoimmune diseases. The aim of this study was to investigate the serum expression of HSP-70 in ITP children and healthy controls.
Materials and methods
A total of 86 children aged 1–6 years were enrolled in the study. The participants were divided into 20 newly diagnosed ITP (ndITP), 34 chronic ITP (cITP) patients and 32 healthy children. The white blood cells and platelet counts were determined and compared between the groups. HSP-70 serum levels were analyzed by sandwich ELISA. Data analysis was done using SPSS and the data variables assessment was done through histogram, probability plots and Shapiro–Wilk tests to determine normal distribution.
Results
The white blood cell counts were 8.9 (4.2–10.4) for new diagnosis ITP, 7.1(3.9–11.9) for the chronic ITP group and 7.0 (4.3–9.5) for the healthy controls. The platelet counts were significantly increased in the chronic ITP group, 83.5(31.7–297) compared to the ndITP group 27.4 (3.7–63.7), but significantly lower compared to the healthy controls 271(172–462) (P = 0.0009). There were significantly increased HSP-70 serum levels in cITP patients compared to the ndITP and the healthy group. In addition, there was a positive correlation between the serum HSP-70 level and the thrombocyte counts among the ITP children.
Conclusions
HSP-70 has a role in the progression of childhood ITP. Increased HSP-70 level is associated with the severity of childhood primary ITP.

Abstract
SUMMARY Dexamethasone is approved as second-line therapy in pediatric chronic immune thrombocytopenic purpura (ITP). Several B-cell abnormalities have been described in ITP pathogenesis.This study assessed the effects of high-dose dexamethasone (HD-DXM) on the percentages and absolute counts of CD19+CD24hiCD38hi regulatory (Bregs) and CD19+CD27+ memory B lymphocytes (Bmems) in children with chronic ITP during active bleeding.The study was a prospective case-control, included 20 children with chronic ITP and uncontrolled bleeding. Children received a single daily dose of HD-DXM for 4 days. Blood samples were withdrawn from patients just before HD-DXM therapy and on day 5 to evaluate the platelet counts and flow cytometric analysis of Bregs and Bmem. The patients' platelet counts significantly increased after 5 days of the initiation of therapy (P=0.0001). Bmems percentage and absolute counts were significantly higher in patients before treatment (P=0.0007), and decreased after HD-DXM therapy (P=0.97) compared with the controls. Bregs percentage and absolute counts were significantly lower before treatment (P=0.0003) and increased after HD-DXM (P=0.003). There is a negative correlation between platelet counts and Bregs percentage and absolute count Bmems percentage before and after HD-DXM, whereas a positive correlation between platelets and Bregs before and after dexamethasone has been reported. CONCLUSIONS HD-DXM reestablishes the normal Bregs/Bmems balance. This finding discloses possible involvement of Bregs and Bmems in the pathogenesis of pediatric ITP and provides a novel vision for immune modulation and treatment perspectives.

Abstract
Atopic dermatitis (AD) is a chronic disease affecting 10–30% of children and 2–10% of adults worldwide. It is manifested by the pruritus eczema lesions on the skin. Immune thrombocytopenic purpura (ITP) is the most common cause of acute onset of thrombocytopenia in childhood. The aim of this study was association of primary immune thrombocytopenic purpura and atopia among children. This case control study was performed on patients with acute and chronic ITP who were confirmed by a hematologist. The control group was also selected from the siblings of the patients who were healthy and almost matched by age and sex with the patient group. Data were entered into a questionnaire under the SPSS-20 program, and demographic data were analyzed descriptively. In the present study, 120 patients were enrolled, 60 of whom were in the patient group and 60 in the control group. Mean age was 95 and 98 months for patients and control. This study showed a significant association of ITP with allergic rhinitis (P = 0.02), atopic dermatitis (P = 0.004), itching (P = 0.042), and dry skin (P = 0.015). However, no significant relationship was found between ITP and asthma (P-value = 0.18). This study does not reveal the causality between atopy and ITP but clearly shows the association between atopy and ITP disease, so the prevalence of atopy in ITP patients is higher than the normal population. According to the results of this study, it is necessary to investigate the cause of atopy and ITP and to find other immunological and possibly genetic commonalities.

Abstract
The purpose was to determine the status of the cerebral arterial compliance (cAC) in a concomitant head injury and cerebral vasospasm (CVS) with and without the development of intracranial hematomas (ICH). In Materials and Methods, we examined 80 polytrauma patients with severe TBI and CVS. During or immediately after dynamic helical computed tomography angiography (DHCTA), the monitoring of the transcranial Doppler of the MCA was recorded bilaterally with 2-MHz probes. The cerebral blood volumes were calculated from the DHCTA data with complex mathematical procedures using the "direct flow model" algorithm. In Results, CAC was significantly decreased (p < 0.001) in both the first and second group TBI and CVS (with or without ICH) in comparison with normal data (p < 0.001) and TBI without CVS. The cAC was significantly decreased on the side of the former hematoma with CVS than on the contralateral side with CVS (р = 0.003). In Conclusion, the cAC in TBI and CVS gets significantly lower as compared to the normal condition (p < 0.001). After removal of the ICH and development of CVS, the compliance in the perifocal zone remains much lower (р = 0.003) as compared to compliance of the other brain hemisphere.

Abstract
BACKGROUND Allergic contact dermatitis (ACD) is common in clinical practice, but the aetiology of this disease is quite varied. A leading pathogenetic mechanism is a cell-mediated immunity. The combinations of ACD with other allergic and systemic autoimmune diseases are relatively rare, but these conditions are undoubtedly a professional challenge for practitioners. CASE REPORT We present a case of ACD combined with other immune-allergic conditions. Aetiology and pathogenesis in these cases are not well understood. CONCLUSION Based on the data from the general and targeted allergic history, patient's subjective complaints, clinical picture, allergenic status, paraclinical results, and the presented photo material, the final diagnosis is as follows: Contact allergic dermatitis-acute form.

Abstract
BACKGROUND Several studies have reported the epidemiology of immune thrombocytopenia (ITP) among children in the United States and other countries. However, recent trends in ITP among hospitalized children and hospital course remain unknown at a national level in the United States. METHOD Hospital discharge records of patients with ITP aged 19 years and younger were obtained for the years 2003, 2006, 2009, and 2012 using the Kids' Inpatient Database. Data were weighted to estimate the annual hospitalization rates in the United States with trend analyses. Multivariable regression models were used to ascertain trends of health care utilizations, hospitalization costs, and length of stay. RESULTS Total annual hospitalization rates due to ITP ranged from 6.13 per 100,000 children in 2003 to 6.22 per 100,000 children in 2012 (Ptrend=0.86). The lowest proportions of hospitalizations were observed in August. The proportions of inpatients treated with intravenous immunoglobulin increased from 18.5% in 2003 to 39.9% (Ptrend< 0.001), while those examined with bone marrow aspiration decreased from 7.8% in 2003 to 6.5% in 2012 (Ptrend=0.01). Total hospitalization costs and length of stay changed from $6147 and 3.78 days in 2003 to $9328 and 2.55 days in 2012. CONCLUSIONS We provided insights of epidemiology of ITP and health care utilizations in the United States. Further studies, including cost-effective analyses, will be required to justify the increasing trends in health care costs and intravenous immunoglobulin.

Abstract
Background Immune (idiopathic) thrombocytopenic purpura (ITP) is a primary autoimmune disease. It is characterized by a diminished peripheral platelet count (< 100 × 109/L) caused by platelet destruction with an increased risk of mucocutaneous bleeding. The diagnosis of ITP depends on clinical characteristics and the laboratory examinations conducted, as well as the ability to exclude other diseases associated with thrombocytopenia. Antiplatelet autoantibodies are responsible for platelet destruction and probably for inhibition of megakaryopoiesis. B lymphocytes participate in immune responses through production of antibodies, antigen presentation to T cells, and cytokine secretion. The aims of this study were to investigate the levels of Bregs and memory B lymphocytes in newly diagnosed pediatric ITP patients and to correlate their levels with the course of the disease. Methods This study was a case-control study. The study included 30 patients with acute ITP. The patients were recruited from Pediatric Clinical Hematology Unit of Children Hospital, Assiut University. In addition, 20 healthy children of comparable age and sex were taken as controls. The institutional review board approved the study and informed consents were obtained. Results There is a significant alteration of B-cell homeostasis in patients with ITP. Conclusion Analysis of Bregs and memory B cells could serve as prognostic markers and might guide therapy in ITP patients in the future.
