Background and Objectives: Laparoscopic splenectomy (LS) has become the gold standard for patients with immune thrombocytopenic purpura (ITP). The total remission rate after splenectomy is 70%–90%, of which 66% is long-term. Despite this high response rate, some patients do not benefit from surgery. It is therefore important to try to identify risk factors for an unsatisfactory clinical response. The aim of this study was to assess long-term outcomes of LS for ITP and identify factors associated with increased disease remission rates. Materials and Methods: We retrospectively studied consecutive patients with ITP undergoing LS in a tertiary referral surgical center prospectively recorded in a database. Inclusion criteria were: Elective, laparoscopic splenectomy for diagnosed ITP, and complete follow-up. The cohort was divided into two groups—Group 1 (G1) patients with ITP remission after splenectomy and Group 2 (G2) patients without remission. There were 113 G1 patients and 52 G2 patients. Median follow-up was 9.5 (IQR: 5–15) years. Results: In univariate analysis, patient’s age, body mass index (BMI), preoperative platelet count, the need for platelet transfusions, and presence of hemorrhagic diathesis were shown to be statistically significant factors. Next, we built a multivariate logistic regression model using factors significant in univariate analysis. Age <41 years (odds ratio (OR) 4.49; 95% CI: 1.66–12.09), BMI <24.3 kg/m2 (OR: 4.67; 95% CI: 1.44–15.16), and preoperative platelet count ≥97 × 103/mm3 (OR: 3.50; 95% CI: 1.30–9.47) were shown to be independent prognostic factors for ITP remission after LS. Conclusion: The independent prognostic factors for ITP remission after LS revealed in our study are: age <41 years, BMI <24.3 kg/m2, and preoperative platelet count ≥97 × 103/mm3. Duration of the ITP and the time of treatment are not related to remission after LS.

Abstract Background: Despite the popularity of splenectomy has decreased dramatically in the past few years, the surgical approach remains the best therapy for patients with refractory Immune Thrombocytopenic Purpura (ITP) in terms of high and durable rate of response (Vesely et al, Ann Intern Med2004; 140: 112). The recent introduction of anti-CD20 antibodies and thrombopoietins of second generation such as AMG 531 and Eltrombopag may have a relevant role (Kuter et al, Lancet2008; 371: 362) but their long-term safety and efficacy have not been still established. In parallel with new drugs, there has been an evolution in the surgery of splenectomy as well (Dolan et al, Am J Hematol2008; 83: 93). Actually, the laparoscopic surgery is considered the standard approach and the ITP represents the most common indication in 50–80% of all the laparoscopic splenectomies. Methods: The aim of this study is to evaluate the long-term complete and partial haematological response (CR + PR), as well as the short and long-term complications, of 40 patients (30 females and 10 males; median age: 38 years - range 6–71) with unresponsive ITP after one or more medical approaches and underwent laparoscopic splenectomy at our Institution from 1999 through 2006. The 40 patients accounted for 22.2% of 181 patients diagnosed in those years. An abdominal CT scan to evaluate the presence of accessory spleens was performed in all cases. All patients received meningococcal, pneumococcal and haemophilus influenzae vaccine one week before splenectomy. For 4 or 5 days before splenectomy the patients were treated with high doses of intravenous Immunoglobulins. Anti-thrombotic prophylaxis was performed with low molecular weight heparin (LMWH) for 10 days and afterwards with cardioaspirin (ASA) if the platelet count exceeded 500x10E9/L. Results: No cases required conversion to laparotomic splenectomy. An accessory spleen was found in 2 patients (5%). Immediate haematological response rate was of 100%. At date, after a median follow-up of 78 months (range 28–112 months), 36 patients (90%) remain in CR or PR with a platelet count more than 50x10E9/L and 2 patients are taking ASA. Four patients (10%) relapsed; out of which, 2 patients have a platelet count less than 10x10E9/L. Short and long-term mortality rate was 0%. Immediate postoperative complications rate was 5%: we observed 2 cases of hemoperitoneum related to a trocar’s tube and to an active bleeding, respectively, both resolved with new laparoscopic approach. The mean postoperative hospital stay was 4,5 days (range 4–8). Neither cases of bacterial sepsis in the postoperative or during the follow-up time, nor cases of splenic-portal vein thrombosis (SPVT) and no cases of neoplasms occurred. Conclusions: Our experience suggests that laparoscopic splenectomy is an excellent approach to patients with refractory ITP in terms of safety, efficacy and costs. With respect to laparotomic splenectomy, the use of laparoscopy is likely to make the splenectomy even safer and therefore suitable for a larger number of patients. Undoubtedly there is a great expectation for the new drugs (Rodeghiero et al, Am J Hematol2008; 83: 91) and we agree that only controlled comparative clinical trials (Vianelli et al, Haematologica2005; 90: 72) will be able or not to say a final word and to challenge the role of splenectomy.

Abstract Abstract 4465 Background Immune Thrombocytopenic Purpura (ITP) is a common hematological disorder. We sort to characterize the risk profiles and efficacy of anti D immunoglobulin in chronic ITP in a largely minority cohort. Methods 31 patients (pts) with chronic immune thrombocytopenic purpura treated 2003-2008 were studied as a retrospective cohort for clinical presentation, prognostic characteristics, time to next therapy and long term survival. Prognostic factors, time to relapse and overall survival was analyzed using fisher's exact test, logistic regression, Kaplan Meier survival analysis and Cox Proportional Hazards model. Results 31 pts 19(61.3%) female and 12(38.7%) male. 11 (35.5%) African Americans, 12(38.7%) Hispanic, 5 (16.2%) Asians and 3 (7.8%) Caucasians. Median age at diagnosis was 44 yrs (21-66). 25 (80.5%) were HIV negative and 6 (19.5%) had HIV. 16 (51.6%) had O positive blood group, 9 (29.6%) had A positive and 4 (12.9%) had B positive. The median number of co-morbidities at diagnosis was 1(0-6). Median age at which anti D immunoglobulin was initiated was 45 yrs. Pt had received a median of 3 (2-6) therapies prior to anti D therapy. All patients had received steroids, 17 (54.8%) had immunoglobulin therapy, 2 (6.5%) had vincristine and 6(19.3%) had splenectomy prior to anti D therapy. The median duration to anti D therapy was 6 months (0-228). Anti D therapy was given in the dose of 50-75mcg/kg IV weekly. Median number of doses given was 2 (1-7) doses. The response rate was 64.5%. Response was defined as Complete response, platelet count of > 100 × 109/L, Partial response >30 × 109/L. 17 (54.8%) achieved complete response, 3 (9.7%) achieved partial response. 11(35.5%) did not respond. Median time to relapse was 4 months (0-79). 9 (29%) achieved a complete response for over a year. Pt with HIV (p=0.013), O blood group (p=0.030) had a significant poor response to anti D therapy on univariate analysis. Pt with HIV (p=0.035) had poor response to therapy on multivariate analysis. O blood group (p=0.001), HIV (p=0.016), > 2 lines of therapy (p=0.007), one dose of anti D (0.037) were associated with shorter time to progression on univariate analysis. On multivariate analysis prior immunoglobulin administration (p=0.039), >2 lines of therapy (p=0.004) and single dose of anti D immunoglobulin (p=0.039) were associated with shorter time to progression. Conclusion Anti D immunoglobulin had a response rate of 64.5% which is similar to other studies. About 29% of patients had a complete response for over a year. Pts who not received anti D immunoglobulin, HIV negative and early anti D administration had the best response and longer time to progression. Disclosures: No relevant conflicts of interest to declare.

Abstract Background and Objectives Immune thrombocytopenic purpura (ITP) is a rare disease, and the epidemiology and long-term outcome are still rarely characterized. This study is then aimed to provide a population-based assessment for the demographics and outcome about ITP in Taiwan, an island in Southeastern Asia with around 23 million inhabitants. Material and Methods This study used claims data from Taiwan's National Health Insurance Research Database (NHIRD). The database included information from a nationwide, mandatory-enrollment and single-payer healthcare system with more than 99% coverage rate in Taiwan since March, 1995. To address adequate medical history tracking and outcome follow-up, only those patients with the first ITP diagnosis from Jan 1st, 2001 to Dec 31st, 2012 were included. Incident ITP was identified first with ICD-9 codes; but those cases with codes for potential ITP-confounding diseases within 6 months from the first ITP code were excluded. Next, only those patients with meaningful pharmacological treatment or splenectomy within 3 months were included in the final analysis. Chronic ITP was defined for those with ICD-9 ITP codes and continuous drug exposure for more than 3 months, or with rituximab or splenectomy. Sex- and age-matched cohorts with 1:10 ratio were selected from Taiwan general population for survival comparison. Results Of the 30673 patients with ITP codes from Jan 1st, 2001 to Dec 31st, 2012, 11437 were identified as incident ITP. The mean age was 42.9+/-27.5 y/o, and 5445 (47.6%) cases had Charlson Comorbidity Index (CCI) score more than 2. The average incidence was 4.16 per 100,000 person-year, and the details are shown in Table 1. The incidence for female was higher than that for male (4.97 vs. 3.38 per 100,000 person-year), and the incidences across the age represented a U-shape distribution, with the highest ones in those aged 0-9 y/o and more than 70 y/o (7.21 and 13.3 per 100,000 person-year, respectively). Some geographic distribution of the incidences existed, with the highest in central part and the lowest in Eastern part of Taiwan (5.33 and 2.64 per 100,000 person-year, respectively). Secondary causes could be identified in 3560 (31.0%) cases, and malignant neoplasma (1743, 49.0%) were most frequently noted. Viral hepatitis B or C were found in 785 (22.1%) cases. Chronic ITP was diagnosed during follow-up in 29.1% (n=3324) of incident ITP patients. Those incident ITP patients aged 0-9 y/o (431/2169 vs. 2893/9268, p<0.001) or male gender (1118/4697 vs. 2206/6740, p<0.001) had a less chance to develop chronic ITP. As compared with the matched cohort from general population, the 10-yr survival rate was significantly inferior for all ITP patients, no matter in those aged below 20 y/o (96.9+/-0.5% vs. 98.8+/-0.1%, p<0.0001) or above 20 y/o (62.5+/-0.8% vs. 83.2+/-0.2%, p<0.0001), as in Figure 1. For chronic ITP, the disadvantaged 10-yr survival rates persisted (for age below 20 y/o: 96.5+/-1.0% vs. 98.6+/-0.2%, p<0.0001; for age above 20 y/o: 72.7+/-1.3% vs. 86.7+/-0.4%, p<0.0001, as in Figure 2). Elder age, male gender and high CCI scores predicted worse survival in multi-variate analysis. Conclusions This study is the largest population-based epidemiology report at nationwide scale till now. Not only the results can provide a valuable demographic description for ITP in Eastern Asia, but also they confirm an inferior long-term outcome for ITP patients, which necessitates more attention to their health care.

Splenectomy is definitive treatment for idiopathic thrombocytopenic purpura (ITP) because it removes both the sites of autoantibody producing cells and also the major site of platelet destruction. The purpose of this study was to evaluate long term results of splenectomised patients with ITP and to determine predictor factors for good response. A 167 patients with chronic ITP (136 females, 31 males), median aged 35 years (17-74) was splenectomised after 2 to 160 months (Median 12) from diagnosis of ITP. Indications for splenectomy were: 6 weeks of steroid therapy with platelet count below 10x10^9/l or 3 months with platelet count under 30xl0^9/l, or treatment with prednisone above 30 mg more of 6 months to increase platelet count over 30x10^9/l, or repeated relapses. Postoperative complications developed in 16 patients (9.5%), 3 of them died (1.8%) due to thromboembolism and 17 patients discontinued later controls. During follow up to 172 months (Median 62) 111/147 splenectomised patients were in remission (75.5%), 99 in complete (above 100x10^9/l), 12 in partial (50-100x109/l) and 36 patients (24.5%) were relapsed (below 50x10^9/l). Remission was achieved in 79/88 patients (89.8%) with good response to prednisone before splenectomy toward 32/62 patients (51.6%) with poor response to prednisone (p<0.01). Remission was obtained in 9/11 patients (81.8%) who responded well to intravenous immune globulin (0.4 g/kg x 5d) and only in 1/8 who did not (p<0.05). Higher response rate was achieved in patients under 40 years of age (81.6%) than in older ones (63.4%) (p<0.05). No difference was shown between sex and time intervals (3, 6, 12, 24, 36 or over 36 months) from diagnosis to splenectomy. Splenectomy is an effective treatment of refractory ITP with response rate of 75.5% after median follow up of 62 months. In our patients better results on splenectomy were associated with age less than 40 years, good responses to steroid, and intravenous immune globulin.

Abstract Abstract 4461 Background Immune thrombocytopenic purpura (ITP) is characterized by mucocutaneous purpura and thrombocytopenia caused by circulating anti-platelet auto-antibodies. ITP is usually self-limited in children, but around 20% of patients will develop chronic ITP. The conventional treatments for children chronic ITP include intravenous immunoglobulin (IVIG), corticosteroid therapy, anti-D immune globulin, or splenectomy. Some children with chronic ITP are refractory to these treatments and nowadays begun to try new treatment agents such as rituximab. Rituximab as a monoclonal antibody to CD-20, has shown promising reports to these patients with refractory chronic ITP in adults groups and a few children groups. We investigated this study to evaluate the efficacy of rituximab for childhood chronic ITP in Korea. Methods We reviewed the questionnaires and medical records about the clinical progresses and results in thirteen children from eight clinical institutes, retrospectively. Complete response (CR) was considered if the platelet count was > 100,000/uL. Results Thirteen patients with chronic thrombocytopenia who had been treated with rituximab were investigated. Two patients were lost to follow-up after rituximab. Finally eleven patients were evaluated including one patient with Evans syndrome. Median age was 6.5 year (range, 0.5 ∼ 15.4). Median platelet count at baseline was 13,700/uL (3,000∼46,000). All patients had been treated with conventional therapy including IVIG and steroids. One had done splenectomy. Median follow-up duration was 2.8 years (1.1-5.9). Among 11 patients, CR was achieved in 3 patients (27%). Their platelet count prior to rituximab were < 10,000/uL. They were treated as the regimen of 375 mg/m2/dose weekly for 4 doses. Time from the first rituximab dose to achievement of complete response was 3.9, 4.9 and 5.7 weeks respectively. One patient who was relapsed 6months after the first course of rituximab was received second course of rituximab using the same regimen and achieved a new CR at 9.3 weeks after. There were no reports about severe complication or interruption of medication. Conclusions Therefore, we suggest that rituximab is effective treatment choice in childhood refractory chronic ITP and well tolerated. Disclosures: No relevant conflicts of interest to declare.
