    Evaluation of the association between null genotypes of glutathione-S-transferases and Behcet's disease
    Uzunoglu, S; Acar, H; Okudan, N; Gökbel, H; Mevlitoglu, I; Sari, F
    Glutathione S-transferases (GST) play an important role in oxidative stress related syndromes. An imbalance of the oxidant and antioxidant systems is important in the pathogenesis of Behcet's disease (BD). The objective of this study was to evaluate the association of null genotypes of GST-M1 and GST-T1 with BD since some preliminary molecular genetic data were recently published. Ninety-four Turkish BD patients (42 male, 52 female, 37.1 +/- 10.4 years) and 140 healthy volunteers (70 male, 70 female, 36.8 +/- 11.7 years) matched for age and gender with the patients as the control group were included in the study. Distributions of GST-M1 and GST-T1 genotypes were determined by multiplexed PCR using three sets of primers for GST-M1, GST-T1, and beta-globulin genes. There was no association between BD and the frequencies of GST-M1 and GST-T1 null genotypes when compared to controls by separate analysis. However, by cross and pooled combination analysis there was a significant association between the frequencies of pooled GSTs with one or both null genotypes in BD and controls. This is the first evidence that the association between the frequencies of GST-M1 and GST-T1 null genotypes and BD might be dependent on the interaction of multiple null allele polymorphisms rather than a single null allele of GST-M1 and GST-T1.

    The levels of adhesion molecules in essential thrombocythemia
    Bilgir, F; Bilgir, O; Calan, M; Sari, F
    Aim. It is known that thrombocytosis is closely related to vascular complications and particularly thrombosis in essential thrombocytemia (ET) cases. The aim of this study is to investigate a possible correlation between adhesion molecules and vascular attacks as well as the relation of these molecules to the platelet count. Methods. The study group consisted of 30 ET patients and 30 healthy controls subjects. Serum intracellular adhesion molecule-1 (ICAM-1), serum vascular adhesion molecule-1 (VCAM-1) and serum E-selectin levels were determined by ELISA method according to manufacturer's instructions. Results. There were no significant differences between two groups with respect to levels of sICAM-1 and sE-selectin (P>0.05). The VCAM-1 levels and platelets were significantly higher in patients with ET compared to controls (P=0.000). Spearman's correlation analysis revealed that sVCAM-1 levels were correlated with platelet counts (r=0.574, P<0.001) Conclusion. High VCAM-1 level in ET and its correlation with the platelet count suggest that these may be a factor in vascular complications and thrombocytosis.

    BackgroundThis study evaluated of clinical characteristics, outcomes, and mortality risk factors of a severe multisystem inflammatory syndrome in children admitted to a the pediatric intensive care unit.MethodsA retrospective multicenter cohort study was conducted between March 2020 and April 2021 at 41 PICUs in Turkey. The study population comprised 322 children diagnosed with multisystem inflammatory syndrome.ResultsThe organ systems most commonly involved were the cardiovascular and hematological systems. Intravenous immunoglobulin was used in 294 (91.3%) patients and corticosteroids in 266 (82.6%). Seventy-five (23.3%) children received therapeutic plasma exchange treatment. Patients with a longer duration of the PICU stay had more frequent respiratory, hematological, or renal involvement, and also had higher D-dimer, CK-MB, and procalcitonin levels. A total of 16 patients died, with mortality higher in patients with renal, respiratory, or neurological involvement, with severe cardiac impairment or shock. The non-surviving group also had higher leukocyte counts, lactate and ferritin levels, and a need for mechanical ventilation.ConclusionsIn cases of MIS-C, high levels of D-dimer and CK-MB are associated with a longer duration of PICU stay. Non-survival correlates with elevated leukocyte counts and lactate and ferritin levels. We were unable to show any positive effect of therapeutic plasma exchange therapy on mortality.ImpactMIS-C is a life-threatening condition.Patients need to be followed up in the intensive care unit.Early detection of factors associated with mortality can improve outcomes.Determining the factors associated with mortality and length of stay will help clinicians in patient management.High D-dimer and CK-MB levels were associated with longer PICU stay, and higher leukocyte counts, ferritin and lactate levels, and mechanical ventilation were associated with mortality in MIS-C patients.We were unable to show any positive effect of therapeutic plasma exchange therapy on mortality.
