ABSTRACT
Background: Immune thrombocytopenia (ITP) is an acquired immune-mediated disease that lacks an underlying etiology. Steroids are the main first-line treatment of ITP, while the second-line treatment consists primarily of splenectomy and rituximab. This study aimed to assess and compare the response to rituximab and splenectomy. Methods: This retrospective comparative study reviewed ITP patients treated at a single private hematology clinic from 2007 to 2019. Seventy-four ITP patients were recruited, 27 were on rituximab, and 47 had undergone splenectomy. The initial platelet counts and bleeding symptoms were recorded, and initial and long-term responses to treatment were evaluated based on the American Society of Hematology guidelines. Results: The mean age of the patients was 42.1 years with a male-to-female ratio of 1:1.8. The initial mean platelet count was comparable between the rituximab and splenectomy groups (p = 0.749). The initial complete response (CR) differed significantly between the rituximab and splenectomy groups (44.4% versus 83%, p = 0.002). The five-year response rate was significantly higher in the splenectomy than in the rituximab group (74% versus 52%, log-rank 0.038). Splenectomy was the only significant predictive factor for long-term response (OR = 0.193, p = 0.006). Conclusion: The overall response revealed that splenectomy appeared superior to rituximab as a second-line treatment of ITP. Splenectomy was the only positive prognostic indicator of sustained response.
ABSTRACT
While many studies addressed the outcome of adult ALL in developed Western countries, there is paucity of such prospective studies from developing Mediterranean ones. This is a prospective cohort study conducted at Hiwa Cancer Hospital in Sulaimani city and Nanakali Hospital in Erbil city-Kurdistan Iraq from March 2012 to August 2017. The main characteristics of adult ALL patients, type of therapy and risk factors were analyzed to assess their impact on treatment outcome and survival status. A total of 109 adult ALL patients were included with a median age of 24 years and male to female ratio of 1.7:1. B-ALL accounted for 76.1% of the cases, while the rest were T-ALL. BCR-ABL rearrangement was encountered in 12% of B-ALL. Complete remission (CR) rate was 81.7%, the overall 5 year survival (OS) was 38%, Relapse Free 5 year Survival (RFS) was 49%. Younger adults (< 35 years) had significantly higher CR rates and OS compared to the older group (P < 0.001 each). On the other hand, gender, high leucocyte count ≥ 50×109/L, immunophenotype (including B and T ALL subtypes), and clinical risk status did not predict a poor outcome. Multivariate analysis revealed that only age < 35 years and BCR-ABL rearrangement were significantly associated with better OS. Despite some limitations, the outcomes of Iraqi adult ALL is comparable to those reported in Western developed countries, with particularly favorable outcomes in younger patients. The need to improve outcome in adult ALL remains an important priority in our country as it is throughout the world.
