Idiopathic thrombocytopenic purpura(ITP) is characterized by the development of a specific anti-platelet autoantibody immune response mediating the development of thrombocytopenia. Systemic lupus erythematosus(SLE) is an autoimmune disease characterized by the production of a wide variety of autoantibodies. We experienced SLE patient whose initial symptoms were related to idiopathic thrombocytopenic purpura(ITP). She has a thrombocytopenia after Splenectomy and Steroid therapy on ITP and SLE. After she took Eight constitution Acupuncture treatment, thrombocytopenia has improved. We think Acupuncture will be effective treatment at autoimmune disease.

Giant platelet syndrome is a group of unique disorders characterized by the presence of abnormally large platelets, and usually accompanied by thrombocytopenia. Most cases of giant platelets are encountered in idiopathic thrombocytopenic purpura(ITP). In contrast, inherited giant platelet disorders, a group of heterogeneous diseases, are rare. Bernard-Soulier syndrome and its variants, and MYH9 related diseases have been defined at the molecular level. Abnormalities in transcription factors are implicated in a couple of macrothrombocytopenia syndromes. However, the molecular defects are unknown in gray platelet syndrome. It is important to make a proper diagnosis of congenital macrothrombocytopenia to avoid unnecessary medications and potentially dangerous treatment for presumed ITP.

Immune thrombocytopenic purpura(ITP) is an autoimmune disease characterized by increased peripheral platelet destruction due to antibody to platelet, which results in thrombocytopenia and cutaneous or mucosal bleeding. Bleeding generally occurs when platelet counts fall to less than $20,000/{\mu}L$. Children affected with ITP are usually healthy prior to the onset of the disease and typically present suddenly after a viral infection or insidiously with progressive petechiae, bruising, or purpura. In most cases the disease is self-limited; approximately 80% of children recover by 6 months after diagnosis, with or without treatment. Children with thrombocytopenia persisting for more than 6 months are defined as having chronic ITP. Clinical manifestations, diagnosis, laboratory findings, differential diagnosis and various treatment modalities are reviewed.

Immune thrombocytopenia (ITP) is a disease in which thrombocytopenia occurs because of immune-mediated platelet destruction and decreased platelet production. Although many pediatric patients with ITP experience spontaneous remission or reach remission within 12 months of first-line therapy, approximately 20% progress to chronic ITP. Patients who do not respond to first-line treatment or experience frequent relapses are of great concern to physicians. This review summarizes recent treatments for second-line treatment of pediatric chronic ITP.

Background: Patients with chronic ITP (idiopathic thrombocytopenia) frequently do not require comprehensive medication for daily life. Usually, it had been regarded that postoperative bleeding after a simple or surgical extraction is easily controlled by simple local measures even in patients with ITP. This lack of regular medication usage can sometimes lead practitioners or patients to underestimate the potential life-threatening risk of ITP. There had been no report on postoperative hemorrhage in a patient with ITP related to dental implant surgery. Case presentation: This report presented a life-threatening postoperative hemorrhage after dental implant surgery in an adult with chronic ITP and subsequent emergency management after severe bleeding and airway compromise. Conclusion: The presented case emphasizes the thorough hematological evaluation of the patients even for patients who do not take any specific medications for asymptomatic, chronic ITP.

We report the case of a 16-month-old patient with chronic immune thrombocytopenia (ITP) patient who experienced delayed treatment-free response (TFR) after romiplostim treatment. He received intravenous immunoglobulin every month to maintain a platelet count above 20,000/µL for 2 years. Thereafter, he received rituximab and cyclosporine as second-line therapy, with no response, followed by romiplostim. After 4 weeks of treatment, the platelet count was maintained above 50,000/µL. Following 7 months of treatment, he discontinued romiplostim, and the platelet count decreased. His platelet counts remained above 50,000/µL, without any bleeding symptoms, 2 years after romiplostim discontinuation. This is the first report of TFR after romiplostim treatment in pediatric chronic ITP.

Thrombocytopenic patients without detectable bound antiplatelet antibody should be diagnosed with idiopathic thrombocytopenic purpura (ITP) if no other cause of their decreased platelet count could be found. More recently the term "autoimmune thrombocytopenic purpura (ATP) has supplanted ITP since the disease is related to the production of autoantibodies against one's own platelets. This entity should not be confused with isoimmune thrombocytopenic purpura (also called alloimmune thrombocytopenic purpura). In this cases maternal antiplatelet antibodies directed against the PLA 1 antigen on the fetal platelets causes severe fetal and neonatal thrombocytopenia in a situation analogous to Rheusus disease. Antibodies to the negatively charged phospholipids, lupus anticoagulant, and anticardiolipin have been linked to adverse pregnancy events. Pregnant women possessing these antibodies have an increased risk of spontaneous abortion, stillbirths, intrauterine fetal growth retardation, preterm birth, and arterial and venous thrombosis. Antiphospholipid antibodies decrease or may even disappear between pregnancies only to recur with increased activity in a subsequent pregnancy and lead to loss. We have experienced a case of antiphospholipid syndrome associated with autoimmune thrombocytopenic purpura in patient with recurrent spontaneous abortion. So we report this case with a brief review of literatures.

인플루엔자 백신 접종에 의한 특발성 혈소판 감소증은 드물게 나타나지만, 인플루엔자 감염환자에서 병발한 혈소판 감소성 자색반증은 거의 보고된 바가 없다. 특이 병력 없던 건강한 5세 남자 환자가 고열과 독감 증상으로 내원하였으며, 혈액검사에서 심한 혈소판 감소증을 보였다. 환아는 신속항원검사, 실시간 중합효소연쇄반응을 통해 B형 인플루엔자 감염을 확진받았으며, 골수 천자 및 생검을 포함한 다른 검사실 검사상 혈소판 감소를 유발할만한 다른 원인은 보이지 않았다. 환아는 정맥 면역글로불린과 프레드니솔론 투여로 정상 혈소판 수치를 회복하였다. 본 증례는 B형 인플루엔자로 인한 혈소판 감소성 자색반증의 첫번째 증례이다. 드물지만 인플루엔자 감염에서도 이처럼 심한 혈소판 감소가 동반될 수 있으므로 외래에서 독감 의증 환자를 진찰할 때에는 멍이나 출혈 흔적 등을 놓치지 않도록 세밀하게 진찰해야 하고 의심이 될 때에는 혈액 검사가 필요할 것으로 생각된다.

목 적: SLE에서는 진단 당시 및 경과 중에 약 15-20%에서 혈소판 감소가 발생하며, 5-16%에서는 혈소판 감소증이 첫 임상증상으로 발생할 수 있으므로 소아 ITP와 SLE와의 연관성이 강력히 제기되고 있다. 한편 항핵항체는 여러 자가면역질환의 선별검사로 주로 이용되고 있는데, 특히 자가면역질환의 임상증상이 발현되기 수개월 혹은 수년 전에 발현될 수 있다. 따라서 저자들은 소아 ITP로 진단된 환자들에서 항핵항체 검사의 양성률 및 임상적 의의를 조사하고자 본 연구를 시작하였다. 방 법: 2003년 1월부터 2006년 12월까지 부산대학교병원 소아청소년과에서 급성 ITP로 진단 받고, 진단 당시에 항핵항체 검사를 시행하였던 77예의 환아를 대상으로 하였다. 항핵항체 검사는 정량 및 정성 검사를 시행하였고, 1:40 이상을 양성으로 판정하였다. 항핵항체 검사 상 양성인 환자들은 1년 이상 역가를 주기적으로 추적관찰 하였다. 결 과: 1) 진단 당시 항핵항체 검사를 시행한 77예의 ITP 환자 중 남아는 38예(49.4%), 여아는 39예(50.5%)였으며, 평균 연령은 4.5세였고, 16예(20.8%)에서 항핵항체 검사 상 양성을 보였다. 2) 항핵항체 양성인 군에서 항핵항체의 정량 역가의 분포는 1:80-1:1,280으로 1:640이 16명 중 5명(30.7%)으로 가장 많았고, 항핵항체의 형은 homogeneous 형이 16명 중 6명(37.5%)으로 가장 많았다. 3) 항핵항체가 양성인 군의 평균 연령은 9.3세로 음성인 군의 3.3세에 비해 진단 당시 평균 연령이 의미 있게 높았다(P<0.05). 4) 항핵항체가 음성인 군의 남녀비는 비슷하였던 반면 항핵항체가 양성인 군은 여아가 81.3%로 현저히 높았다(P<0.05). 5) 진단 당시 혈소판 정중값은 항핵항체 양성군에서는 $18,400/{\mu}L$, 음성군에서는 $21,800/{\mu}L$으로 두 군 사이에 의미 있는 차이가 없었다. 6) 진단 당시 항핵항체의 역가 및 형은 만성 ITP 및 SLE로의 진행과 의의있는 관련이 없었다. 7) 급성 ITP 진단 당시 항핵항체 양성이었던 환자 중 1명이 추적관찰 41개월 후 SLE로 최종 진단되었다. 결 론: 소아 급성 ITP 환자에서 ANA 양성인 경우가 비교적 흔한 것으로 나타났으며, 만성 ITP와 SLE로의 진행에 대한 연관성은 더 많은 환자를 대상으로 한 연구를 통하여 밝혀져야 할 것이다.
