Objective:The Turkish Society of Pediatric Hematology set up a National Hemoglobinopathy Registry to demonstrate the demographic and disease characteristics of patients and assess the efficacy of a hemoglobinopathy control program (HCP) over 10 years in Turkey.Materials and Methods:A total of 2046 patients from 27 thalassemia centers were registered, of which 1988 were eligible for analysis. This cohort mainly comprised patients with β-thalassemia major (n=1658, 83.4%) and intermedia (n=215, 10.8%).Results:The majority of patients were from the coastal areas of Turkey. The high number of patients in Southeastern Anatolia was due to that area having the highest rates of consanguineous marriage and fertility. The most common 11 mutations represented 90% of all β-thalassemia alleles and 47% of those were IVS1-110(G->A) mutations. The probability of undergoing splenectomy within the first 10 years of life was 20%, a rate unchanged since the 1980s. Iron chelators were administered as monotherapy regimens in 95% of patients and deferasirox was prescribed in 81.3% of those cases. Deferasirox administration was the highest (93.6%) in patients aged <10 years. Of the thalassemia major patients, 5.8% had match-related hemopoietic stem cell transplantation with a success rate of 77%. Cardiac disease was detected as a major cause of death and did not show a decreasing trend in 5-year cohorts since 1999.Conclusion:While the HCP has been implemented since 2003, the affected births have shown a consistent decrease only after 2009, being at lowest 34 cases per year. This program failure resulted from a lack of premarital screening in the majority of cases. Additional problems were unawareness of the risk and misinformation of the at-risk couples. In addition, prenatal diagnosis was either not offered to or was not accepted by the at-risk families. This study indicated that a continuous effort is needed for optimizing the management of thalassemia and the development of strategies is essential for further achievements in the HCP in Turkey.

This study showed that plasma levels of TAFI, PAI-1, D-dimer, AT III and thrombomodulin were significantly increased in women with PCOS compared with age- and BMI-matched controls.

A 31-year-old patient with multiple sclerosis (MS), treated with interferon beta-1b (IFNB-1b) for two years, presented with fatigue and dizziness. Coombs' positive autoimmune hemolytic anemia (AIHA) was found. Other potential etiologies of AIHA were ruled out. An association with IFNB-1b was highly suspected. Interferon therapy was discontinued and prednisone therapy instituted. There was resolution of the hemolytic anemia, and prednisone therapy was tapered gradually. To the best of our knowledge, there is no reported case of the development of AIHA associated with IFNB-1b use in MS patients. We conclude that if an unexplained drop in hematocrit occurs with a MS patient receiving IFNB-1b, autoimmune mediated hemolysis should also be considered.

A 42-year-old woman was diagnosed with myelodysplastic syndrome with fibrosis that developed bilaterally, cervical lymphadenopathy and cutaneous infiltration by trilineage extramedullary hematopoiesis after granulocyte colony-stimulating factor therapy because of severe neutropenia. Hepatosplenomegaly was not observed during her follow-up. Extramedullary hematopoiesis disappeared after growth factor therapy was stopped. Although the neutropenia was alleviated by growth factor administration, the appearance of an unusual involvement of extramedullary hematopoiesis should be kept in mind.
