How complicated can be a case with immune thrombocytopenic purpura?: postsplenectomy arterial thrombosis.

Arterial thrombus associated with the surgery can be seen in postsplenectomy cases, but there is no clear data in patients diagnosed with immune thrombocytopenic purpura (ITP). A 52-year-old female patient was admitted to the emergency department due to ecchymotic skin changes. Her initial platelet count was 6000/mm 3 ; after two courses of high dose-dexamethasone, intravenous immunoglobulin and rituximab, splenectomy was planned for the patient whose platelet count was again <40 000/mm 3 . She presented to the emergency department with complaints of pain and pallor in the right arm in the second week of follow-up. There was a mural thrombus that caused approximately 50% stenosis in the lumen at the division site in the aortic arch, proximal of the right subclavian artery. The patient's clinic was found to be associated with the presence of an aberrant right subclavian artery and postoperative thrombocytosis/inflammation after elimination other prothrombotic conditions.

Effect of interleukin-2 (IL-2) polymorphisms on multiple myeloma: IL-2RA rs2104286, IL-2 rs2069762 and rs2069763 polymorphisms.

Interleukin-2 (IL-2) is a cytokine secreted from T helper type 1 cells and released after induction of T helper cells with major histocompatibility complexes or antigens presented by antigen presenting cells. IL-2 activity and gene polymorphisms have been studied in both solid and hematological malignancies. In the present study, it was aimed to examine the effects of IL-2RA rs2104286, IL-2 rs2069762 and rs2069763 polymorphisms on multiple myeloma (MM) susceptibility, progression-free survival (PFS) and overall survival (OS). A total of 300 patients diagnosed with MM in our clinic between January 2010 and January 2021, and 170 healthy individuals were included. In addition to the demographic data of the patients, MM subtypes, initial stages, prognostic index scores, laboratory results, treatment preferences, and survival data were recorded. The genotypes of the IL-2RA rs2104286, IL-2 rs2069762 and rs2069763 polymorphisms were statistically compared between patients and healthy controls to reveal their effects on MM susceptibility and survival. In the statistical analysis performed to examine the effect of IL-2RA rs2104286, IL-2 rs2069762 and rs2069763 polymorphisms on disease susceptibility, no significant difference was found between the patient and healthy control groups. Patients with the TG genotype of IL-2 rs2069762 had a significantly shorter median PFS and OS compared to others. Patients with the GG genotype of IL-2 rs2069763 had a significantly shorter median PFS compared to others. Having the TG genotype of IL-2 rs2069762 has been shown to be protective for short PFS and OS. Our study results will be guiding in terms of IL-2 based therapies, the future for MM and MM epigenetics.
