特发性血小板减少性紫癜(idiopathic thrombo cytopenic purpura,ITP)是临床常见的出血性疾病。部分慢性反复发作经内科药物治疗效果不佳,或严重出血不能控制者,采用脾切除治疗有效率70%~90%。通常脾切除术后可导致血小板升高,血液黏稠度增加,严重者可致血栓形成。2007年1月-2009年7月我院共施行ITP脾全切术54例,有效52例,现报道如下。 相似文献

目的回顾性分析比较脾切除术和免疫抑制剂分别对肾上腺糖皮质激素治疗不敏感或激素依赖的特发性血小板减少性紫癜(ITP)患者的疗效,以探讨适宜的二线治疗方案。方法收集广州市5家三级甲等医院,1997—2007年近10年间住院的所有诊断为ITP且对激素治疗无效的患者共52例,对其临床资料进行分析。根据不同的治疗方案将其分为2组,A组20例为脾切除组,B组32例为使用免疫抑制剂组(包括环孢菌素A、硫唑嘌呤、长春新碱,环磷酰胺)。分别比较两组患者在治疗前、治疗后第3天、7天、1月、6月、24月时的血小板计数(BPC)及治疗副作用。结果A组患者从治疗第3天起至24个月BPC均高于B组,差异有显著性(P〈0.05)。A组的总有效率高于B组,差异有显著性(P〈0.05)。A组治疗副作用包括术中出血、伤口愈合不良、脾切后继发感染等,发生率为15.0%;B组治疗不良反应包括感染、骨髓抑制、肝损害、‘肾损害、出血性膀胱炎、末梢性周围神经炎及其他等,发生率为45.0%。其中4例免疫抑制剂治疗无效的患者行脾切除后仍能达到有效。个别切脾后疗效不佳者仅需小剂量激素和(或)联用免疫抑制剂维持。结论对激素治疗不敏感或激素依赖的ITP患者,脾切除治疗起效时间快,效果好,副作用少,可作为激素治疗失败或不能耐受者的首选二线治疗方法。 相似文献

Chronic idiopathic thrombocytopenic purpura in adult Chinese patients: a retrospective single-centered analysis of 1791 cases 总被引:16,自引:1,他引:16
Background Adult chronic idiopathic thrombocytopenic purpura (ITP) is a common hematologic disease characterized by persistent thrombocytopenia. So far, there were only a few reports on adult Chinese patients with chronic ITP. This study aimed at defining the treatment outcome and prognostic factors for chronic ITP based on a large cohort of Chinese patients followed up for over 25 years at a single center.Methods The medical records of 1791 patients aged 14 years or older who were diagnosed as having chronic ITP at our hospital from 1974 to 1999 were retrospectively analyzed.Results The female-to-male ratio was 2∶1, with a median age of 34 years (ranging from 14 to 80 years), median platelet count of 38×10(9)/L [range (1-99)×10(9)/L], and median follow-up of 36 months (range 1-220 months). Steroids were used in 689 patients, among them 209 (30.3%) achieved complete remission (CR). A splenectomy was performed in 124 patients, and response to steriod pre-splenectomy was not available in 14 patients. The CR rate after a splenectomy was lower in steroid nonresponders (29 of 90, 32.2%) than in those who relapsed after successful steroid treatment (12 of 20, 60.0%) (P<0.05). In comparison with patients negative for antinuclear antibody (ANA), those who were ANA positive had similar responses to steroids, but a significantly shorter remission period after a splenectomy (P<0.01).Conclusions Adult Chinese chronic ITP patients can have long-term remission after steroid therapy and splenectomies. Primary steroid refractoriness is a prognostic factor predicting poor subsequent response to a splenectomy. 相似文献

Background High anatomic location, fragility, and generous blood supply of the spleen makes laparoscopic splenectomy (LS) difficult to master, and few patients need splenectomy for benign disorders. The aim of this research was to assess operative outcomes and hematological results of a large series of patients treated with LS for chronic immune thrombocytopenic purpura (ITP) and to determine which clinical variables predict favorable hematological outcome.
Methods LS was successfully performed for 154 patients with chronic ITP from September 1999 to April 2009 at the First Affiliated Hospital of Sun Yat-sen University. Operative outcomes were assessed retrospectively. Long-term follow-up data were obtained from outpatient medical records and phone interviews. Clinical and laboratory variables (including gender, age, disease duration before surgery, previous response to steroids, preoperative platelet count, and postoperative peak platelet count) were evaluated by univariate analysis to identify potential predictors of hematological outcome. Multivariate Logistic regression model was used to determine independent predictors of hematological outcome.
Results One patient died from subphrenic abscess and postoperative sepsis. The overall major morbidity rate was 8.4%. None of the patients required a second surgery for complications. Of the 127 patients available for a mean follow-up of 43.6 months (range 9–114 months), the overall initial response (i.e., at two months after LS) and long-term response to LS were achieved in 89.0% and 80.3%, respectively. Five patients (3.9%) developed pneumonia 3–35 months after LS. Univariate analysis showed a significant difference in mean age between responders (29.1 years) and nonresponders (38.8 years; P <0.05). Patients who responded to steroid therapy had better hematological outcome than those who did not respond (P <0.05). Compared to nonresponders, responders to LS had a significantly higher postoperative peak platelet count (404×109/L versus 213×109/L, P <0.001). Multivariate Logistic regression analysis identified postoperative peak platelet count as the only independent predictor of favorable response to LS ( P <0.001).
Conclusions LS is a safe and effective treatment for chronic ITP. Postoperative peak platelet count may serve as a major predictor of long-term response.

OBJECTIVE: To determine whether Helicobacter pylori eradication is an effective treatment for Australian patients with chronic immune thrombocytopenic purpura (ITP). DESIGN, SETTING AND PATIENTS: Retrospective analysis of clinical records of a consecutive series of ITP patients referred to a gastrointestinal surgeon in a tertiary referral hospital for laparoscopic splenectomy between August 2005 and November 2007. MAIN OUTCOME MEASURES: Platelet response (measured at least 3-monthly) following successful H. pylori eradication therapy (confirmed by urea breath test 4 weeks later). RESULTS: Of 16 patients, seven were H. pylori-negative and underwent laparoscopic splenectomy. Nine were H. pylori-positive and successfully underwent H. pylori eradication therapy; five of the nine had an initial platelet response. Four patients had platelet counts > 100 x 10(9)/L (reference range, 140-450 x 10(9)/L) and were off all immunosuppression at 9 months; three had a sustained response beyond 12 months. One patient had an initial response at 3 months (15 x 10(9)/L to 208 x 10(9)/L), but relapsed 4 months after H. pylori eradication and underwent splenectomy with platelet count recovery. The remaining four patients showed no platelet response and subsequently underwent splenectomy. CONCLUSION: Larger prospective studies are needed to fully ascertain the role of H. pylori in Australian patients with ITP. However, H. pylori eradication is simple and safe. H. pylori screening and eradication should be considered before immunosuppression or splenectomy. 相似文献

High doses of dexamethasone in adult patients with idiopathic thrombocytopenic purpura 总被引:2,自引:0,他引:2
Gutiérrez-Espíndola GR Morales-Polanco MR Guerrero-Rivera S Talavera JO Sánchez-Valle E Gómez-Morales E Pizzuto-Chávez J 《Archives of medical research》2003,34(1):31-34
BACKGROUND: High-dose dexamethasone (DXM) has been used in treatment of patients with idiopathic thrombocytopenic purpura (ITP) who are refractory to other treatments such as prednisone and splenectomy; nevertheless, different studies show variable success rates, this postulated as possibly being due to racial differences. The objective of this study was to determine DXM effectiveness at high doses in Mexican mestizo adult patients diagnosed with ITP with and without splenectomy. METHODS: Nonhospitalized adult patients with ITP were included, eight patients previously splenectomized (group 1) and 11 who had not undergone splenectomy (group 2). Patients received DXM 40 mg/day intravenously (i.v.) during 4 consecutive days every 4 weeks until six cycles were completed. RESULTS: There were no differences between the two groups regarding age (mean 39 vs. 33 years of age) and initial platelet count (M 17 vs. 24 x 10(9)/L). Median evolution time was 84 months for group 1 and 7 months for group 2 (p = 0.002). Of 19 patients, nine achieved a favorable response (FR), six belonged to group 1, and three to group 2 (Fisher p = 0.07). Nevertheless, after 6 months only two group 1 patients and two group 2 patients maintained FR (Fisher exact test p = 1). Patients achieving FR to initiation of second cycle maintained FR at the end of six cycles. CONCLUSIONS: Thus, the previously mentioned high-dose DXM therapy appears to be useful for both patients with ITP with and without splenectomy and high-dose DXM appears to be a good alternative therapy for postsplenectomy and relapse patients. However, duration of FR to treatment was brief; therefore, other treatment plans might be required to achieve longer remission duration. Response was similar to that observed in other studies carried out in different populations; thus, apparently no genetic or racial variations exist. In addition, whether patients not responding after second cycle should continue until completing the 6-month plan or should try a different therapeutic approach must be considered in the treatment plan. 相似文献
