Vascular involvement in Behçet's disease (BD) occurs in up to 50% of patients. The main mechanism of thrombosis is inflammation. Thus, immunosuppressants (IS) are the mainstay of therapy, and adding anticoagulation (AC) is controversial. ⋯ Eight (19.6%) patients were not receiving any treatment during relapses. The recurrence rate was statistically significantly lower in the IS + AC treatment group compared to IS alone. In conclusion, IS are the mainstay of treatment for BD, and adding AC may help to lower the recurrence risk of thrombotic events.

It has been shown that 25-OH vitamin D not only preserves calcium and bone homeostasis but also has immunomodulatory effects. The purpose of this study was to assess the association between adult patients with recently diagnosed immune thrombocytopenia (ITP) and vitamin D levels. Retrospective technique was employed in this study. ⋯ There was no statistically significant difference in terms of relapse-free survival in all three groups (p = 0.71). In conclusion, in our study, no correlation was found between laboratory and clinical findings at diagnosis and vitamin D levels in adult ITP patients. Additional investigations, particularly randomized controlled trials, are required to examine the relationship between 25(OH)D and the incidence and severity of ITP.

Hypercoagulable disorders are best described as a group of acquired and hereditary conditions that increase the risk for the development of thrombi within veins or arteries. In the setting of an unprovoked venous thromboembolism, common practice in the inpatient setting has been further investigation via a thrombophilia workup to establish an underlying cause. Current Hematology-Oncology guidelines argue against inpatient workup as the results rarely influence inpatient management. ⋯ There was a relationship between appropriate thrombophilia testing and Hematology-Oncology consultation. This demonstrates the need for expert consultation if thrombophilia testing is being considered. The current study provides more evidence that a strong recommendation against inpatient testing should be made as testing does not aid in diagnosis or change management and is an overutilization of healthcare resources.

Acute myeloid leukemia (AML) is a hematologic malignancy characterized by the proliferation of CD34 positive self-renewing malignant hematopoietic stem cells. Previous studies have shown that the transforming growth factor beta (TGFβ) pathway plays a role in AML pathogenesis, especially by affecting the microenvironment. Growth differentiation factor 11 (GDF11) is a member of the TGFβ superfamily, involved in embryological development and known as rejuvenating factor. ⋯ A positive correlation was detected between GDF11, E-cadherin, and vimentin levels. As a conclusion, increased serum GDF11 levels in AML patients may be linked to the regeneration ability of leukemic stem cells. There is a need for studies investigating GDF11 expression in myeloblasts.

Multiple myeloma (MM) is a bone marrow malignancy characterized by plasma cell proliferation. It was aimed to investigate pentraxin 3 (PTX3) levels, oxidative/antioxidative status, and their correlation in MM. In the study, four groups were established, including newly diagnosed MM (NDMM), MM in remission (Rem-MM), relapsed/refractory MM (RRMM) patients, and a healthy control group. ⋯ Multivariate analysis confirmed associations between MM groups and PTX3 levels. Receiver operating characteristic analysis revealed high specificity (90%) and sensitivity (79%) for PTX3 in NDMM at a >0.56 ng/mL cut-off value. This study suggests that PTX3 levels may have diagnostic and prognostic potential in MM and its relationship with oxidative stress requires further exploration.
