THA in Patients with Idiopathic Thrombocytopenic Purpura (ITP): A Case Report / Journal of Rural Medicine

We report a case of idiopathic thrombocytopenic purpura (ITP) accompanied by steroid-induced avascular necrosis of the femoral head in a 68-year-old woman. Extremely low platelet counts of ITP patients prohibit any surgical interventions. Her platelet count was 25,000/μL. We performed a total hip arthroplasty with high-dose immunoglobulin therapy and transfusion of platelet concentrates. Her platelet count increased to 94,000/μL just before the operation. No hemostatic complications were encountered perioperatively, and the postoperative course was uneventful. She left the hospital 20 days after the operation with a T-cane. Her platelet count decreased to 34,000/μL on the day she left the hospital. Three years after the operation, she had no groin pain and could walk without ambulatory assistive devices. We did not observe implant loosening.

Initial Therapy with High-Dose Dexamethasone for Patients with Idiopathic Thrombocytopenic Purpura

BACKGROUND: Corticosteroids have been widely used for treatingidiopathic thrombocytopenic purpura (ITP) as a first-line treatment. Several different pulsed high-dose dexamethasone therapies for adult ITP have been reported on. We assessed the effectiveness of a single course of high dose dexamethasone as first-line treatment for adult patients with ITP. METHODS: The subjects of the study were previously untreated adult patients with newly diagnosed ITP and who had a platelet count of less than 20,000/microliter or a platelet count less than 50,000/microliter. High-dose dexamethasone at a dose of 40mg/day for four consecutive days was given orally. A response was defined as an increase in the platelet count of at least 30,000/microliter and a platelet count of more than 50,000/microliter by day 10 after the initial treatment. A sustained response was defined as a platelet count of more than 50,000/microliter that was maintained for six months after the initial treatment. RESULTS: Twenty two patients were eligible. The median platelet count before treatment was 19,000/microliter. Seventeen patients (77%) among the 22 patients achieved an initial response by day 10: the mean platelet count 10 days after the initial treatment was 144,000/microliter (range: 51,000 to 428,000/microliter). Among the patients with a response, 4 (23.5%) had a sustained response, and the other 13 (76.5%) relapsed within six months. All the patients well tolerated the high-dose dexamethasone treatment. CONCLUSION: A single course of high-dose dexamethasone is effective as an initial treatment for adults ITP patients, although the response duration is short. To maintain the response, repeated high-dose dexamethasone treatment may be needed or other alternative therapies can be considered.

A Case of Peripartum Cardiomyopathy associated with Preeclampsia superimposed on Idiopathic Thrombocytopenic Purpura / 대한산부인과학회지

Peripartum cardiomyopathy is a dilated cardiomyopathy of unexplained cause that occurs during the last trimester of pregnancy or within 5 months after delivery. And, It is a rare disease that has a frequency of 1 in 1,300-15,000 deliveries. It has not yet been reported that peripartum cardiomyopathy has occurred in an preeclampsia woman superimposed on idiopathic thrombocytopenic purpura. Moreover, the association between idiopathic thrombocytopenic purpura and peripartum cardiomyopathy has not been studied. Recently, we experienced a case of a woman who has undergone emergency Cesarean section due to complicated severe preeclampsia superimposed on idiopathic thrombocytopenic purpura. On the postoperative day, this patient developed respiratory distress and pumonary edema. Peripartum cardiomyopathy was diagnosed by echocardiography and we present with a brief review of literatures.

Resolution of Chronic Idiopathic Thrombocytopenic Purpura after Eradication of Helicobacter pylori: A Case Report / 대한혈액학회지

Helicobacter pylori (H. pylori) has been recognized as a main cause of gastritis and most cases of peptic ulcer, gastric adenocarcinoma, and mucosa-associated lymphoid tissue lymphoma. An immunological response to H. pylori infection has been suggested to play a major role in determining gastroduodenal damage through the production of cytokines and the autoantibody against gastric epithelial cell. H. pylori has been implicated in the pathogenesis of some autoimmune disease, such as Sjogren disease, Henoch-Schnlein purpura, rheumatoid arthritis, autoimmune thyroid disease, and idiopathic thrombocytopenic purpura (ITP). Serveral studies recently showed a high prevalence of H. pylori infection in patients with ITP and reported a platelet recovery after bacterial eradication therapy. We report a case of a 54-year-old man with chronic ITP who was resolved after eradication of H. pylori.

Laparoscopic Splenectomy for Chronic Idiopathic Thrombocytopenic Purpura

PURPOSE: In chronic idiopathic thrombocytopenic purpura (ITP), primary treatment is steroid therapy. However treatment with steroids effects a complete response in less than 30% of the patients whereas a splenectomy is successful in more than 60% of the patients who undergo it. The minimal access afforded by a laparoscopic splenectomy (LS) is considered highly desirable for these patients. The purpose of this study was to compare the clinical benefits of a LS with those of conventional open surgery (OS) for patients with ITP. METHODS: The results of 12 subsequent laparoscopic splenectomies performed from December 1996 to May 1998 were compared with those of 10 open splenectomies performed from September 1987 to May 1995. The indications of a splenectomy were medical intractability, recurrent ITP and/or complications of steroids. The operative time, the time to resumption of oral intake, the postoperative hospital stay, the platelet count, the postoperative response rate, the incidence of accessory spleen, and the period of complication after preoperative steroid administration were statistically analyzed (t-test, chi-square test). Also, the timing of the splenectomy was compared. RESULTS: The operative time was longer in the LS patients (LS 221 min, OS 127 min, p=0.0033), but the length of stay (LS 9.3+/-3.87 days, OS 4.6+/-1.92 days, p=0.0033) and duration of ileus (LS 2.9+/-0.32 days, OS 1.9+/-0.90 days, p=0.0002) were shorter in the LS group. There were no significant differences in platelet count, postopertative response rate, and incidence of accessory spleen between the two groups. Accessory spleens were found in 4 patients (18%). The conversion rate was 17% (only 2 initial cases). The splenectomy had been chosen as a second-line treatment in 91.7% and 60% of the LS and OS patients, respectively, and as a third-line treatment in 8.3% and 40% of those patients, but these result have no statistical significance. The time interval between diagnosis and operation also was not significantly different, between the two groups. CONCLUSION: A LS is safe and effective for the management of ITP and allowsrapid recovery. A LS should be the early treatment of choice for patients, who do not response to primary steroid therapy or who have recurrent or complicated ITP. When such patients are managed early surgical laparoscopic treatment, the side effects of steroid may be minimized.

Clinical Significance and Detection of Antibodies Against Platelet GP Ib/I X and Gp II b/IIIa in Childhood Chronic Idiopathic Thrombocytopenic Purpura / 대한소아혈액종양학회지

BACKGROUND: Chronic idiopathic thrombocytopenic purpura is an autoimmune disorder caused by sequestration of antibody-sensitized platelets in the reticuloendothelial system. However, uncertainty as to the specificity, frequency and clinical significance of such antibodies still remains. So, we tried to further clarify the above uncertainty in childhood chronic idiopathic thrombocytopenic purpura. METHODS: We analyzed sera from 29 patients. Twenty six patients were chronic ITP who were admitted or followed up to the Department of Pediatrics, Severance Hospital, Yonsei University Medical College from August 1996 to March 1997 by employing a modified antigen-capture ELISA(MACE), flow cytometry and electrophoresis(SDS-PAGE) and immuno-blotting(IB) assays. Three patients with ITP less than 6 months after onset of ITP were included to know the possibility to differrentiate between acute ITP and chronic ITP in this study. RESULTS: 1) Glycoprotein(GP)-specific antibodies were found in 28% (8/29) of patients, with 2 patients having antibodies directed solely to Gp II b/III a, no patients holding antibodies specific only for GPI b/I X and 6 possessing antibodies against both anti-GP I b/I X and Gp II b/III a antigen. 2) The detection rate of GP-specific antibodies of flow cytometry was about 10%. The positivity of anti-GPI b/I X antibodies by MACE and immunoblotting was 14% (4/29), respectively, the positivity of anti-Gp II b/III a antibodies by MACE and immunoblotting was, 21 % (6/29) respectively. The concordance rate between two assays(MACE and IB) was 79% (23/29). None of the three methods was good enough to stand alone. 3) Serum antibodies were not more frequently detected in active(p=1.0) or non-splenectomized(p=.54) chronic ITP patients. 4) No association was found between antibody specificity(anti-GPI b/I X, anti-Gp II b/ III a) and platelet counts(p : .87). CONCLUSION: We conclude that in korean childhood chronic ITP, antibodies against both anti-GPI b/I X and Gp II b/III a antigen were predominant antibody. But, the longterm follow-up in more cases is needed to further clarify the clinical significance of antral-platelet antibody in chronic ITP should be assessed.

A Case of New Vessels on the Optic Disc(NVD) Associated with Idiopathic Thrombocytopenic Purpura(ITP)

The most common ocular finding of the idiopathic thrombocytopenic purpura(ITP) is superficial retinal hemorrhages in both eyes. But the descriptions of new vessel on the optic disc(NVD) associated with ITP are scarcely found in literatures. A 17-year-old girl who managed for ITP complained of visual distrubance of the right eye and floaters of the left eye. On fundoscopy the right eye was failed to examine due to thick vitreous hemorrhage and the left eye showed NVD and preretinal hemorrhage. After panretinal photocoagulation of the left eye, NVD was regressed.

Relationship between idiopathic thrombocytopenic purpura and virus infection in children / 重庆医科大学学报

Objective:To study the relationship between idiopathic thrombocytopenic purpura (ITP) and various virus infections in children.Methods:The human parvovirusB 19(HPV-B 19),Epstein-Barr virus(EBV),Cytomegalovirus and Coxsackie virus (CBV 1-6) were detected using ELISA test in 102 patients with ITP.Results:The HPVB-19 IgM was positive in 41 patients(40.12%).CBV1-6 IgM was positive in 28 patients(27.45%).The CMV IgM was positive in 17 patients(16.66%).The EBV IgM was positive in 7 patients(6.86% ).The total rate of these four viruses was 50.98% of the patients with ITP observed in this study.Except EBV,the virus infections positive rate in this study were significantly higher than that of control group.( P
