Evaluation of 143 Cases of Immune Thrombocytopenic Purpura With Regards to Clinical Course and Response to Treatment

Objective: Immune thrombocytopenic purpura (ITP) is also known as idiopathic thrombocytopenic purpura. Increased platelet destruction and insufficient platelet production are both responsible for its etiopathogenesis. ITP can be diagnosed after excluding other possible causes of thrombocytopenia. Materials and Methods: One hundred forty-three cases of chronic ITP that were monitored in a hematology clinic were retrospectively evaluated. All cases received first line treatment of 1 mg/kg/day prednisolone. Corticosteroid nonresponsive (CN) cases and corticosteroid- dependent (CD) cases underwent splenectomies. Results: The rate of CN/CD cases was found to be 53% (n=76). Sixty-six percent of these cases (n=50) underwent splenectomies. The ratio of non-responsive cases to relapse cases after splenectomy (SN/SR) was 30% (n=15). The total number of cases was 41, including those without splenectomy (n=26) and with SY/SR (n=15). Helicobacter pylori (Hp) eradication, immunosuppressive agents and danazol treatments were administered to patients (n=10, n=14 and n=4, respectively). Currently, 13 patients are being monitored without treatment. Fifteen patients who were non-responsive to Hp eradication treatment, immunosuppressive treatment or danazol treatment are still being monitored without any treatment. Conclusion: Optimal treatment is not available for splenectomy-resistant cases of ITP. The response rates for Hp eradication treatment, immunosuppressive treatments and anabolic agents are low. Therefore, larger studies with more patients are required using new agents, such as thrombopoietin (TPO) receptor agonists and anti-CD20 monoclonal antibodies

A novel differential diagnosis algorithm for chronic lymphocytic leukemia using immunophenotyping with flow cytometry

Introduction: The availability of a clinical decision algorithm for diagnosis of chronic lymphocytic leukemia (CLL) may greatly contribute to the diagnosis of CLL, particularly in cases with ambiguous immunophenotypes. Herein we propose a novel differential diagnosis algorithm for the CLL diagnosis using immunophenotyping with flow cytometry. Methods: The hierarchical logistic regression model (Backward LR) was used to build a predictive algorithm for the diagnosis of CLL, differentiated from other lymphoproliferative disorders (LPDs). Results: A total of 302 patients, of whom 220 (72.8%) had CLL and 82 (27.2%), B-cell lymphoproliferative disorders other than CLL, were included in the study. The Backward LR model comprised the variables CD5, CD43, CD81, ROR1, CD23, CD79b, FMC7, sIg and CD200 in the model development process. The weak expression of CD81 and increased intensity of expression in markers CD5, CD23 and CD200 increased the probability of CLL diagnosis, (p < 0.05). The odd ratio for CD5, C23, CD200 and CD81 was 1.088 (1.050 - 1.126), 1.044 (1.012 - 1.077), 1.039 (1.007 - 1.072) and 0.946 (0.921 - 0.970) [95% C.I.], respectively. Our model provided a novel diagnostic algorithm with 95.27% of sensitivity and 91.46% of specificity. The model prediction for 97.3% (214) of 220 patients diagnosed with CLL, was CLL and for 91.5% (75) of 82 patients diagnosed with an LPD other than CLL, was others. The cases were correctly classified as CLL and others with a 95.7% correctness rate. Conclusions: Our model highlighting 4 markers (CD81, CD5, CD23 and CD200) provided high sensitivity and specificity in the CLL diagnosis and in distinguishing of CLL among other LPDs

The Role of Plasmapheresis in Acute Rejection with Decompensated Heart Failure after Heart Transplantation

Abstract Background/Aims: In this study, the results of patients who had orthotopic heart transplantation (OHT) in acute rejection who admitted to our clinic with decompensated heart failure and who could not undergo endomyocardial biopsy (EMB) were evaluated. Methods: The study included 27 patients who underwent OHT in our clinic between December 1998 and November 2021, who admitted with acute rejection causing decompensated heart failure during follow-up, and who could not undergo EMB and administered IV pulse steroid plus plasmapheresis. Demographics of patients, peri-treatment left ventricular functions, survival rates and causes of mortality were analyzed. Results: 19 (70.4%) were male and mean age was 28.7 ± 14.7 (range: 3-54). After OHT, overall survival rates were 92.6%, 77.6%, and 69.4% at 1st, 3rd and 5th year respectively. During the follow-up, the survival rates of patients who presented with decompensated heart failure and given pulse steroid plus plasmapheresis were 70.4%, 58.8%, and 53.4% at 1st, 3rd and 5th year respectively after plasmapheresis. Median rejection time after transplant was 19 months (range 0-113 months). Pre-, and post-treatment left ventricle ejection fractions were 25.11% ± 11.1%, and 52.14% ± 13.4% respectively (

Frontline Nilotinib Treatment In Turkish Patients With Philadelphia Chromosome-Positive Chronic Myeloid Leukemia In Chronic Phase: Updated Results With 2 Years Of Follow-Up

Objectives: This report presents final results (24 months of follow-up) from the first prospective, national study of frontline nilotinib in chronic myeloid leukemia (CML) patients in Turkey. Methods: Patients with newly diagnosed Philadelphia chromosome-positive CML in chronic phase (CML-CP; N = 112) received nilotinib 300 mg twice daily. The primary endpoint, which was the cumulative rate of major molecular response (MMR; BCR-ABL1 <= 0.1% on the International Scale [BCR-ABL1(IS)]) by 12 months, was previously reported (66.1% [80% CI, 59.7%-72.0%]). ClinicalTrials.gov identifier NCT01274351 Results: By 24 months, 83.0% of patients achieved MMR, and 50.9% achieved MR4.5 (BCR-ABL1(IS) <= 0.0032%). Safety results at 24 months were consistent with those at 12 months. No additional deaths or disease progressions to accelerated phase/blast crisis were observed between 12 and 24 months. Discussion: Treatment with nilotinib 300 mg twice daily for 2 years provided high MMR with a good safety/tolerability profile in newly diagnosed CML-CP patients in Turkey. Assessment of MMR across time points showed increasing rates through 18 months, after which as lower rate of increase was observed. The safety profile of nilotinib 300 mg twice daily with 24 months of follow-up was similar to that observed at 12 months, and no new safety concerns were identified. These efficacy and safety findings are consistent with the results from the 12-month analysis of this study and from previous nilotinib studies. These findings support nilotinib as an option for frontline treatment of CML-CP. Conclusion: Frontline nilotinib treatment provided sustained efficacy, with good tolerability, over 24 months in newly diagnosed CML-CP patients.WoSScopu

Outcomes with frontline nilotinib treatment in Turkish patients with newly diagnosed Philadelphia chromosome-positive chronic myeloid leukemia in chronic phase

WOS: 000384401200003PubMed ID: 27501474Objective: Nilotinib is a BCR-ABL1 tyrosine kinase inhibitor approved for the treatment of patients with chronic myeloid leukemia in chronic phase (CML-CP). This study was the first prospective evaluation of the efficacy and safety of nilotinib in Turkish patients with newly diagnosed CML-CP. The primary endpoint of the study was the rate of major molecular response (MMR; BCR-ABL10.1% on the International Scale [BCR-ABL1(IS)]) by 12months.Methods: Patients with newly diagnosed CML-CP were treated with nilotinib 300mg twice daily. This analysis was based on the first 12months of follow-up in a 24-month study.Results and Conclusions: Of 112 patients enrolled, 66.1% (80% CI, 59.7-72.0%) achieved MMR and 22.3% achieved a deep molecular response of MR4.5 (BCR-ABL1(IS) 0.0032%) by 12months. During the first year of treatment, 1 patient progressed to blast crisis and 2 patients died. Safety results were consistent with previous studies. Most adverse events (AEs) were grade 1/2. Most frequently reported nonhematologic AEs of any grade were elevations in bilirubin, alanine aminotransferase, and triglycerides. These results support the use of nilotinib 300mg twice daily as a standard-of-care treatment option for patients with newly diagnosed CML-CP.Novartis Pharmaceuticals CorporationNovartisThis study was funded by Novartis Pharmaceuticals Corporation
