Abstract
BACKGROUND Idiopathic thrombocytopenic purpura (ITP) is characterized by a low platelet count. This may lead to an increased risk of hemorrhagic stroke but a lower rate of nonhemorrhagic stroke. The goal of this study was to evaluate the association between ITP and both hemorrhagic and nonhemorrhagic strokes using a large database. METHODS We used the Nationwide Inpatient Sample (NIS) database to analyze the occurrence of hemorrhagic and nonhemorrhagic stroke in patients with and without a diagnosis of ITP from 2005 to 2014. RESULTS Univariate analysis revealed a higher incidence of hemorrhagic stroke in patients with ITP in the year studied. (for example, in 2005: OR, 1.75; 95% CI, 1.57-1.94; P < 0.001; 2014: OR, 2.19; 95% CI, 2.03-2.36; P < 0.001). After adjusting for age, gender, race, and hypertension, hemorrhagic stroke remained significantly associated with ITP (in 2005: OR, 1.85; 95% CI, 1.49-1.89; P < 0.001; 2014: OR, 2.01; 95% CI, 1.86-2.18; P < 0.001) for all the years studied. Nonhemorrhagic stroke occurred at a lower rate in patients with ITP in most years (2006: OR, 0.91; 95% CI, 0.85-0.97; P = 0.004; 2014: OR, 0.88; 95% CI, 0.83-0.93; P < 0.001). Multivariate analysis confirmed a higher rate of nonhemorrhagic stroke in ITP patients. CONCLUSION Our analysis showed that there was a higher rate of hemorrhagic stroke but a lower rate of ischemic stroke in ITP patients, suggesting an important role of platelets in the occurrence of stroke.

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.

Abstract
Idiopathic thrombocytopenic purpura (ITP) mostly presents with bleeding tendencies, and thrombotic events are very uncommon. Our case report presents a male patient with ITP refractory to standardized therapies who continuously showed thrombocytopenia and hematuria. With no evidence of autoimmune diseases or other secondary causes of ITP, he developed recurrent cerebral infarctions and deep venous thrombosis. Our report calls for attention to possible thrombotic events, as well as more common bleeding tendencies in patients with ITP and outlines rehabilitation treatment specially designed for ITP patients with rare thrombotic complications.

Abstract
Guidelines are lacking for management of acute ischemic stroke and stroke prevention in patients with immune thrombocytopenia (ITP). Our aim is to highlight the dilemma inherent in managing patients with both significant bleeding and thrombotic risk factors. In this review, we present two patients with history of ITP who presented with acute ischemic stroke and received tissue plasminogen activator (tPA) and endovascular thrombectomy (EVT), a rare management strategy in this patient population. In addition, we identified 27 case reports of ischemic stroke in patients with ITP; none of them received tPA or EVT. Furthermore, there are 92 patients with significant thrombocytopenia with no available data regarding the cause of thrombocytopenia, who were acutely treated with tPA or EVT. Conclusive evidence cannot be determined based on these limited number of cases. Future multicenter prospective cohort studies in patients with ITP are needed to provide better evidence-based treatment plans. At present, treatment of acute ischemic stroke in patients with ITP requires close collaboration between hematology and vascular neurology experts to find a balance between the benefit and risk of hemorrhagic complications.

Abstract
Immune thrombocytopaenia (also known as idiopathic thrombocytopaenic purpura) (ITP) is a chronic condition with isolated low platelet counts. Although it is largely perceived that ITP predisposes to bleeding risks, thrombotic events, such as ischaemic strokes, do happen paradoxically in patients with ITP. A 68-year-old lady presented with right upper limb weakness and was diagnosed with an ischaemic stroke and was started on clopidogrel. She had a history of ITP. Two months later, she again had another ischaemic stroke. Prednisolone was added as her platelet count was below 50 x 109/L. Based on this case and recent case studies, we suggest the administration of antiplatelet or anticoagulant agents judiciously if the platelet count is 50 x 109/L or above with monitoring of bleeding risks. As for the management of ITP, we do agree with the general opinion that treatment is rarely required for patients with a platelet count above 50 x 109/L. We recommend a haematology consult for discussion on treatment initiation if the platelet count is below 50 x 109/L.

Abstract
INTRODUCTION Immune thrombocytopenic purpura (ITP) is an autoimmune hematological disorder that causes decreased production and destruction of platelets leading to thrombocytopenia. Although thrombocytopenia usually causes hemorrhagic problems, thrombotic events like strokes, although rare, can still occur. Management of thrombotic events in patients with ITP differs from that of patients with normal platelet count function and count. CASE DESCRIPTION A 32-year-old female with a history of ITP presented with ischemic stroke. The patient was treated in the hospital with IV immunoglobulin, discharged to a rehabilitation facility, and had complete resolution of symptoms when examined at a follow-up visit 3 months later. CONCLUSION Although stroke in patients with ITP is very rare due to thrombocytopenia, it has been reported in several other published cases and is likely associated with increased platelet microparticle levels, a byproduct of platelet destruction. While usage of antiplatelet therapy in such patients is debated, immunosuppression therapy has been the mainstay treatment in all published cases.

Abstract
Nowadays, we have a relatively sophisticated standard approach to a patient with acute ischemic stroke, including the sequence of diagnostic methods and treatment modalities. In practice, however, we are occasionally confronted with a patient whose medical history or comorbidities force us to make a decision without the support of guidelines. One such situation is the occurrence of acute ischemic stroke in a patient with known idiopathic thrombocytopenic purpura, where a tendency to use thrombolysis, anticoagulants, or antiplatelet agents collides with the fear of life-threatening bleeding. In this review, we try to outline current understanding of the pathophysiology of "paradoxical" ischemic events in this illness characterized by thrombocytopenia and to summarize clinical experience from case reports dealing with this topic, which could help us to rely on more than individual opinion seen through a purely "neurological" or "hematological" prism.

Abstract
A ten-year-old neutered female mixed breed dog was referred for pale mucous membrane and acute onset of right prosencephalic clinical signs. Brain magnetic resonance imaging was suggestive for right middle cerebral artery ischemic stroke. Based on cell blood count, serum biochemistry and serologic tests and flow cytometric detection of anti-platelets and anti-red blood cells antibodies, a diagnosis of immunomediated haemolytic anemia associated with thrombocytopenia of suspected immunomediated origin was done. Immunosuppresive therapy with prednisone was started and the dog clinically recovered. Two months later complete normalization of CBC and serum biochemistry was documented. The dog remained stable for 7 months without therapy; then she relapsed. CBC revealed mild regenerative anemia with spherocytosis and thrombocytopenia. A conclusive Evans’ syndrome diagnosis was done and prednisone and cyclosporine treatment led to normalization of physical and CBC parameters. The dog is still alive at the time the paper submitted. Possible thrombotic etiopathogenetic mechanisms are illustrated in the paper and the authors suggest introducing Evans’ syndrome in the differential diagnosis list for brain ischemic stroke in dogs.
