    Abstract 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. The associations between 25(OH)D value and platelet count, as well as the clinical symptoms of ITP upon diagnosis and 25(OH)D value, were our main findings. A total of 60 patients diagnosed and followed up in our clinic were included in the study. Forty-one patients (68.3%) were female and 19 (31.7%) were male. The median age of the patients was 52.5 (19-88). The median vitamin D level of all patients at diagnosis of ITP was 11.5 (3-86). There was no statistically significant difference between the patients divided into three groups according to their vitamin D levels, in terms of laboratory parameters. There was no statistically significant difference in clinical findings according to vitamin D status in ITP patients. 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.

    Abstract Calreticulin (CALR) is a calcium-binding protein chaperone that may be found throughout the extracellular matrix and membranes of cells. It regulates calcium homeostasis and ensures the appropriate folding of newly generated glycoproteins within the endoplasmic reticulum. A somatic mutation in JAK2, CALR, or MPL is responsible for the great majority of essential thrombocythemia (ET) cases. ET has a diagnostic and prognostic value because of the sort of mutation that causes it. ET patients with the JAK2 V617F mutation had more noticeable leukocytosis, higher hemoglobin levels, and lower platelet levels, but also more thrombotic problems and a higher risk of PV transition. CALR mutations, on the other hand, are linked to a younger age group, males, with lower hemoglobin and leukocyte counts, but higher platelet counts, and a higher risk of myelofibrosis transformation. There are two predominant types of CALR mutations in ET patients. Different CALR point mutations have been identified in recent years, but their involvement in the molecular pathogenesis of MPN, including ET, is still unknown. In this case report, we presented a rare CALR mutation in a patient who was diagnosed with ET and followed up.

    Abstract A thorough examination of the available literature has revealed a well-established association of obesity and high body mass index (BMI) with an increased risk of various types of cancers, including hematologic malignancies. Specifically, the studies reviewed indicate a clear correlation between obesity and an increased risk of leukemias, lymphomas, multiple myeloma, myelodysplastic syndrome, and myeloproliferative diseases. Despite the established association of obesity and high BMI with hematologic malignancies, the underlying mechanisms remain largely undetermined. The development of hematologic malignancies may be influenced by several mechanisms associated with obesity and high BMI, including chronic inflammation, hormonal imbalances, adiposopathies, and metabolic dysregulation. Furthermore, there is mounting evidence indicating that obesity and high BMI may have a negative impact on the response to treatment and overall survival in patients with hematologic malignancies. This article aims to increase awareness and summarize the current state of research on the impact of obesity on hematologic malignancies, including the mechanisms by which obesity may influence the development and progression of these diseases. In addition, the current review highlights the need for effective weight management strategies in patients with hematologic malignancies to improve outcomes and mitigate the risk of complications.

    Abstract Whilst particular infectious bacteria are well-established to be associated with hematological diseases, more recent interest has focused on the entire microbial community of mucosal surfaces. In particular, the link between hematology and the microbiota (defined as the total assemblage of microorganisms in a mucosal environment)/ microbiome (i.e. the entire ecological habitat, including organisms, their genomes and environmental conditions) is becoming more well-known. Dysbiosis, or a change in the microbiome, has been linked to the development of neoplasms, infections, inflammatory illnesses, and immune-mediated disorders, according to growing data. Microbiota may influence distant tumor microenvironment through a variety of methods, including cytokine release control, dendritic cell activation, and T-cell lymphocyte stimulation. There are numerous major implications to study the microbiome in patients with benign and malignant hematologic disorders. In this review, we investigated the structure and function of the microbiome in patients with benign and malignant hematological diseases. Chemotherapy and immunosuppressive agents used in treatment of these benign and malignant hematological diseases may cause or exacerbate dysbiosis and infectious problems. After understanding the importance of microbiota in hematological diseases, we think that use of probiotics and dietary prebiotic substances targeting microbiota modification aiming to improve hematological disease outcomes should be investigated in future studies.

    Abstract One of the rarest types of hereditary thrombocytopenia is the MYH9-related disorder. This spectrum of disorders is characterized by large platelets with or without leukocyte inclusion bodies, a decrease in the total number of platelets, and autosomal dominant inheritance. Proteinuric nephropathy that frequently progresses to end-stage renal failure, as well as the beginning of progressive high-frequency sensorineural hearing loss in young adults, is also associated with MYH9-related disorder. In this case report, we presented three family members who had thrombocytopenia and in whom a heterozygous novel 22 bp deletion (c.4274_4295del) was detected which is located in exon 31 of the MYH9 gene. There was no evidence of bleeding in the family members we presented and thrombocytopenia was detected incidentally. Additionally, renal failure, hearing loss, presenile cataracts, and clinical symptoms were not detected in these family members. This novel mutation detected in the MYH9 gene has not been reported in the literature before.

    Abstract The emergence of immune checkpoint inhibitors (ICIs) has led to a dramatic paradigm shift within the landscape of cancer treatment, igniting significant interest in their potential application in treating hematologic malignancies. This comprehensive review critically has examined the existing body of literature to shed light on the evolving understanding of the efficacy and safety of ICIs, both as a single agent and in combination regimens in hematologic malignancies. Across distinct lymphoma subtypes, the observed treatment responses exhibit diversity, and conflicts. Notably, Hodgkin lymphoma and certain non-Hodgkin lymphomas such as primary mediastinal B-cell lymphoma, emerge as remarkable cases, showing encouraging response rates and outcomes. However, the efficacy of ICIs reveals variations among subtypes such as chronic lymphocytic leukemia and multiple myeloma. Combination therapies consistently demonstrated superior outcomes compared to monotherapy in several malignancies. While the potential benefits of ICIs in hematologic malignancies are evident, the safety profile warrants careful consideration. Immune-related and other adverse events, though generally tolerable and manageable, highlight the necessity of meticulous monitoring and appropriate intervention. The discussions prompted by these findings underscore the need for tailored treatment approaches, driven by disease subtype, patient characteristics, and potential biomarkers. Moreover, the emerging realm of combination therapies involving immune checkpoint inhibitors holds promise for enhanced treatment outcomes, and ongoing research endeavors aim to unravel the optimal strategies.

    Abstract Ankaferd hemostat (ABS; Ankaferd Blood Stopper®, İstanbul, Turkey) is a hemostatic agent having an impact on red blood cell– fibrinogen interactions. The hemostatic effect of ABS depends upon the quick promotion of a protein network, particularly fibrinogen gamma, in relation to the erythrocyte aggregation. The entire physiological process involves ABS-induced formation of the protein network by vital erythrocyte aggregation. Vital erythrocyte aggregation occurs with the spectrine, ankyrin, and actin proteins on the membrane of the red blood cells. ABS notably affects cell metabolism and cell cycle mechanisms. Meanwhile, ABS has antiproliferative effects on cancer cells. The aim of this review is to assess molecular basis of ABS as a hemostatic drug. The literature search on ABS was performed in PubMed, Web of Science (SCI expanded), and Scopus with particular focus on the studies of molecular basis of ABS, in vivo research, case series, and controlled randomized clinical studies. Current perspective for the utilization of ABS is to provide hemostasis with accelerating wound healing. Future controlled trials are needed to elucidate the pleiotropic clinical effects of ABS such as antineoplastic, antiinflammatory, antiinfective, antifungal, and antioxidative effects.

    Abstract Background: This study aimed to compare the hematological parameters of patients with very high and normal 25-hydroxyvitamin-D3 (25(OH)D3) levels.
    Methods: This study was designed as a retrospective cross-sectional study. The patients were divided into three groups according to their 25(OH)D3 levels: groups 1, 2 and 3 consists of patients with normal 25(OH)D3 levels (30-88 ng/mL), hypervitaminosis D (89-149 ng/mL) and vitamin D intoxication (>150 ng/mL), respectively. According to vitamin D levels, statistical analysis was performed by comparing the biochemical and hematological data between the groups.
    Results: This study evaluated 120 patients (40 patients) in three equal groups. A statistically significant difference was found between the three groups in hemoglobin (P=0.03), hematocrit (P=0.01), red blood cell levels (P=0.03), leukocyte count (P<0.001), neutrophil count (P<0.001), lymphocyte count (P=0.006), mean platelet volume (P=0.04), and neutrophil/lymphocyte ratio (P=0.03). In post-hoc analysis, hemoglobin, hematocrit and RBC were significantly higher in group 1 than in group 3 (post-hoc Tukey, P<0.05). A statistically significant negative correlation was noted between 25(OH)D3 level and hemoglobin (r=-0.236), hematocrit (r=-0.230), and red blood cell (r=-0.265) levels.
    Conclusions: Vitamin D intoxication has been observed to affect hemoglobin, hematocrit, and RBC levels negatively. However, more studies are needed to clarify the effects and mechanisms of high vitamin D levels on the hematopoietic system.
