    Abstract Sars Cov-2, the pathogen which belongs to the beta coronavirus family that is responsible for COVID-19, uses Angiotensin Converting Enzyme 2 (ACE2) as a receptor, which is responsible for controlling the actions of renin-angiotensin system (RAS). Sars Cov-2 - ACE2 binding leads to a RAS mediated immune response, which targets especially lungs to form ARDS, which in turn, is the most important cause of mortality in COVID-19. CD8

    Abstract Background: Hypoxia is the hallmark of iron deficiency anemia (IDA) and in hypoxic environment, significant changes are observed in malignancy-related microRNAs (miRNA). Our aim is to examine whether there is any difference in the levels of miR-210, miR-373 and let-7, which are directly related to malignancies in patients with IDA.
    Methods: Thirty-five female patients with IDA between the ages of 18-65 and 10 healthy controls were included in the study. Patients who received oral iron therapy, who had inflammatory disease, and who were pregnant were excluded from the study. Student t Test was used for comparing variables with normal distribution in two independent groups, and Mann-Whitney U Test was used for variables without normal distribution. Comparison of categorical data was made using the chi-square test.
    Results: The mean hemoglobin and ferritin level were 10,78±0,93 and 6.28±5,76 respectively. Plasma miR-210 expression were found as -7.27±2.23 and -6.15±0,88 in IDA and control group respectively (p = 0.022). Plasma miRNA-373 were -7.36±2,58 and -6,96±1,93 and let-7 expression were 2.14±2,15 and 3,57±2,21 in IDA and control group. (p = 0.65 and p = 0.20, respectively).
    Conclusions: Plasma miR-210 expression was significantly up-regulated and miR-373 and let-7 expression was down-regulated, though insignificantly, in IDA group.

    Abstract Introduction background: This study evaluated the impact of adipose tissue indices on prognosis of HL.
    Methods: Fifty-five patients with newly diagnosed Hodgkin Lymphoma were evaluated retrospectively for association with adipose tissue indices (total abdominal tissue volume, radiodensity, subcutaneous and visceral adipose tissue SUVmax value and prognostic factors for Hodgkin Lymphoma such as IPS-3, IPS-7, stage, sedimentation, progression free and overall survival.
    Results: For IPS-3, SAT SUVmax and TAAT radiodensity were significantly increased in high-risk patients (2and 3) compared to group 0 and 1. For IPS-7, total abdominal adipose volume was significantly decreased in high-risk patients, SAT SUVmax significantly increased in high-risk patients and decreased in low-risk patients. In addition, SAT SUVmax was significantly increased in patients with high sedimentation rate, with B symptoms and who passed away during follow-up. SAT SUVmax showed moderate positive correlation with sedimentation, IPS-3, IPS-7, and stage. In addition, it was observed that TAAT radiodensity and SAT SUVmax were significantly better for determining prognosis than other adipose tissue indices. Roc analysis showed that the diagnostic value of all adipose tissue indices in predicting IPS-3 and IPS-7 prognoses were statistically significant.
    Conclusion: SAT SUVmax and TAAT radiodensity were two new and independent markers with diagnostic value in predicting prognosis.

    Abstract Background: Alterations of plateletcrit and mean platelet volume (MPV) and pathogenesis of chronic lymphocytic leukaemia (CLL) have been linked to various inflammatory disorders. The prognostic impact of plateletcrit and MPV were evaluated.
    Methods: MPV and plateletcrit levels of both CLL and control group were compared and then in CLL patients, additional diseases, leukocyte count, platelet count, lactate dehydrogenase, Rai stage, progression-free and overall survival, mutations, if any, and chemotherapy, if any, were recorded. Then, the relationship between MPV and plateletcrit values and these parameters were evaluated in CLL patients.
    Results: Platelet and plateletcrit values were found to be significantly lower in CLL patients than the control group (p<0.001) for both. Plateletcrit and MPV values of patients who did not receive chemotherapy were higher than those who received chemotherapy (p=0.03, p=0.02, respectively). Being over 75 years old, plateletcrit value less than 0.1565 %, platelet level below 175 x 109/L, and leukocyte count greater than 53.5 x 109/L was found to significantly reduce overall survival. Male gender, each stage increase, plateletcrit less than 0.1565 % and leukocyte count greater than 53.5 x 109/L was related to reduce treatment-free survival in CLL patients.
    Conclusions: Plateletcrit can be a viable prognostic marker for defining both treatment free and overall survival.

    Abstract Probiyotikler yeterli miktarda tüketildiğinde sağlık üzerinde birçok fayda sağlayan canlı mikroorganizmalar olarak tanımlanır. Laktik asit bakterileri (LAB) süt, et, meyve ve sebze gibi gıdaların doğal florasında bulunmakta ve fermente gıdaların üretiminde kültür olarak kullanılmaktadır. Bu bakteriler insan ve hayvanların bağırsak, ağız ve deri, üriner sistemin mikrobiyotalarında da bulunurlar ve bu ekosistemlerde faydalı etki gösterebilirler. Bazı Lactobacillus türleri, Bifidobacterium spp., Saccharomyces boulardii ve diğer bazı mikroorganizmalar sağlığa yararlı olmak amacıyla, gıda takviyesi şeklinde probiyotik olarak kullanılmaktadır. Probiyotiklerin, tedavi sürecinde olan hastaların çoğunda yarar sağladığı bilinse de, bağışıklık sistemi baskılanmış hastalarda risklerin mevcut olduğu belirtilmektedir. Organ ve immün yetmezliği olan ve gastrointestinal bariyerde bozulmaları bulunan hastalarda probiyotiklerin kullanımının enfeksiyonlara neden olabileceğine dair bulgular giderek artmaktadır. Probiyotiklerin bir tedavi seçeneği olarak kullanılması için olumsuz etkilerinin olmadığının kanıtlarla tespit edilmesi gereklidir. Öncelikle probiyotik olarak kullanılacak LAB’nin tanımlanmasında klasik biyokimyasal testlerin yetkin bir laboratuvarda moleküler yöntemlerle tamamlanması önemlidir. Farklı antibiyotiklere direnç, virülans faktörlerinin varlığı ve biyojenik aminlerin sentezi probiyotik bakterilerin güvenilirliği için öncelikle incelenen parametrelerdir. Probiyotiklerin güvenilirliğinin değerlendirilmesinde; probiyotik suşun farmakokinetiği ve probiyotik suş ile konakçı arasındaki etkileşimler üzerine çalışmalar bulunmaktadır. Probiyotikler için güvenlik ve kullanım protokolleri ile ilgili gerekli standartlar bulunmamaktadır. Probiyotiklerin, bir hastalığın tedavisi veya önlenmesi amacıyla kullanılabilmesi için daha fazla bilgiye ihtiyaç duyulmaktadır. Probiyotiklerin olumsuz etki gösterme olasılığını belirleyebilmek için probiyotik kullanımı hakkındaki bilgilerin revizyonu önemlidir.

    Abstract Background/aim: FLT-3 ligand is a growth factor affecting the hematopoietic lineage. The aim of this study was to evaluate the variability of peripheral FLT-3 ligand during the clinical course of acute myeloid leukemia (AML) patients.
    Materials and methods: Twenty-four patients were enrolled in this study in order to assess alterations in the circulating levels of FLT-3 ligand during the clinical course of AML.
    Results: We studied the association in the diagnostic period between the FLT-3 ligand and peripheral blood cells together with serum electrolytes. FLT-3 ligand levels (pg/mL) during the aplastic period due to remission induction and consolidation were higher than the levels at initial diagnosis. On the other hand, the diagnostic and remission induction values of leukocytes and FLT-3 ligand showed an inverse association. These results indicate to us that higher white cell counts are associated with lower FLT-3 ligand levels. We also found a reversed association between FLT-3 ligand and serum lactate dehydrogenase level. However, there was no association between FLT-3 ligand and other serum electrolyte levels. We also found higher FLT-3 ligand levels in male patients.
    Conclusion: Our study demonstrates the inverse proliferative action of FLT-3 ligand on the early myeloid lineage. In addition, this study showed us that FLT-3 receptor inhibition during chemotherapy-induced aplasia causes a compensative ligand overexpression.

    Abstract Imatinib mesylate selectively inhibits bcr/abl and other non-specific tyrosine kinases, such as c-kit and platelet derived growth factor (PDGF) receptor and successfully used to treat chronic myeloid leukaemia (CML). In most cases, the drug is well tolerated: however, side effects can be seen. Hair loss and paronychia inflammation were often reported with Imatinib, but total alopecia was rarely mentioned. We report a CML patient who was presented with alopecia and paronychia inflammation probably induced by imatinib therapy. We have successfully treated our patient by cessation and then re-applying therapy with lower doses after improvement of lesions and have not found a similar report in literature.
