    Purpose: Early comorbidity detection has been reported to be associated with treatment-related outcomes in several diseases. Two main goals of the present study were to investigate both the impact of comorbidities and transfusion frequencies on the survival and quality of life of patients with myelodysplastic syndromes (MDS). Methods: One hundred and four MDS patients with a median International Prognostic Scoring System (IPSS) score of 0.5 (range: 0-3) were included in the study. Almost half of the patients had more than one comorbidity. Results: Median short form health surveys (SF)-36 mental and physical scores were 42.1 (range: 20.6-66.1) and 38.7 (range: 18-59.7), respectively. Mean scores of the Eastern Cooperative Oncology Group (ECOG) performance scales at diagnosis and during recruitment were 1.0 (1.4 +/- 1.0) and 2.0 (1.8 +/- 1.1), respectively. The mean Charlson Comorbidity Index (CCI) score was 1.0 (1.4 +/- 1.5). In the model that was constructed using variables with a p value < 0.100 in the univariate analysis, factors that predicted death were refractory anemia with excess blasts (RAEB) and ECOG scores at recruitment. When ECOG was removed from the model, RAEB and CCI at diagnosis moved to the forefront as mortality predictors. Conclusion: This study demonstrated that both CCI and ECOG performance status had an impact on survival in MDS patients who had low IPSS scores. ECOG stood out as a better and more practical predictor of survival than CCI, especially after considering its (ECOG) ease of use.

    Management of Adult Primary Immune Thrombocytopenia: DelphiBased Consensus Recommendations
    (Galenos Publ House, 2024) Demir, Ahmet Muzaffer; Umit, Elif Gulsum; Ar, Muhlis Cem; Ayer, Mesut; Ayli, Meltem; Karakus, Volkan; Kaya, Emin
    Objective: Primary immune thrombocytopenia (pITP) is an acquired autoimmune disorder related to the increased destruction and/or impaired production of platelets. Its diagnosis and management are challenging and require expertise and the interpretation of international consensus reports and guidelines with national variations in availability. We aimed to assess the agreement of hematologists in T & uuml;rkiye on certain aspects of both first -line and second -line management of patients with pITP. Materials and Methods: Applying a modified Delphi method, the Turkish National ITP Working Group (14 steering committee members), founded under the auspices of the Turkish Society of Hematology, developed a 21 -item questionnaire consisting of statements regarding the first -line and second -line treatment of pITP. A total of 107 adult hematologists working in either university or state hospitals voted for their agreement or disagreement with the statements in two consecutive rounds. Results: The participants reached consensus on the use of corticosteroids as first -line treatment and with limited duration. Methylprednisolone was the corticosteroid of choice rather than dexamethasone. Use of intravenous immunoglobulin was not preferred for patients without bleeding. It was also agreed that thrombopoietin receptor antagonists (TPO-RAs) or rituximab should be recommended as second -line treatment and that splenectomy could be considered 12-24 months after diagnosis in patients with chronic pITP. Conclusion: The optimization of the dose and duration of TPO-RAs in addition to corticosteroids is necessary to improve the management of patients with pITP.
