Effects of circulating endothelial progenitor cells, serum vascular endothelial growth factor and hypogammaglobulinemia in Perthes disease

Objective: The aim of this study was to investigate Legg-Calvé-Perthes disease (PD) pathogenesis by comparing absolute circulating endothelial progenitor cell (EPC) counts, serum levels of vascular endothelial growth factor-A (VEGF-A) and immunoglobulins between PD patients and controls. Methods: The study included 28 PD cases (mean age: 8±3.8) and 25 healthy age-matched control subjects. EPC, serum VEGF-A and immunoglobulin levels were measured in peripheral blood samples. Comparisons and correlation analysis were performed. Results: In the PD group, 17 subjects were in the fragmentation stage and 11 in the healing stage. Four patients had bilateral disease and 14 had hypogammaglobulinemia. Median EPC count of the PD group was 80 and was significantly higher than those of the control group (p=0.011). No significant difference was determined in serum VEGF-A levels (p=0.354). EPC count were inversely correlated with serum IgG levels of the PD group (r=0.403, p=0.03). Absolute EPC count was also significantly higher in the fragmentation stage than in the healing stage and were also greater in bilaterally affected than in unilaterally affected patients. Circulating EPC count was correlated to the serum VEGF-A levels in patients with fragmentation stage of PD (r=0.605, p=0.01) and in those with hypogammaglobulinemia (r=0.599, p=0.001). Conclusion: High EPC count at the fragmentation stage of PD and relatively higher counts in bilateral disease suggest that EPC may be a valuable marker in the diagnosis and follow-up of PD. Additional studies are needed to explain the strong correlation between EPC and serum VEGF-A level in the fragmentation stage and in the presence of hypogammaglobulinemia.Objective: The aim of this study was to investigate Legg-Calvé-Perthes disease (PD) pathogenesis by comparing absolute circulating endothelial progenitor cell (EPC) counts, serum levels of vascular endothelial growth factor-A (VEGF-A) and immunoglobulins between PD patients and controls.

An examination of the relationship between regulatory T cells and symptom flare-ups in children and adolescents diagnosed with chronic tic disorder and Tourette syndrome

Background:Tourette syndrome (TS) is a childhood-onset neurodevelopmental disorder characterized by several motor and phonic tics. Aims:In this study, we aimed to compare activated regulatory T cell (Treg) values between patients with TS/chronic tic disorder (CTD) and age- and sex-matched healthy controls (HCs). Materials and method:Patients with TS/CTD and age- and sex-matched HCs were included in the study. The severity of the disease was evaluated using the Yale Global Tic Severity Scale. CD4(+)CD25(+)CD127(low)Tregs from the patient group and the control group were compared using flow cytometry. Results:The study included 48 patients diagnosed with TS/CTD (36 males and 12 females, mean age: 11.58 +/- 2.61) and 24 HCs (18 males and 6 females, mean age: 11.63 +/- 2.60). The TS/CTD group had significantly higher activated regulatory T percentile with respect to the T helper value compared to the HCs (p = 0.010). Lymphocyte count, T lymphocyte count, T lymphocyte percentage, T-helper lymphocyte count, and T-helper lymphocyte percentage were lower in the patient group compared to the control group (p = 0.024, 0.003, 0.007, <0.001, <0.001, respectively). The comparison of three groups (mild, moderate-severe, and HCs) revealed that T lymphocyte number and percentage and the T helper number and percentage were significantly higher in the HC group compared to the moderate-severe group, whereas the activated Treg percentage with respect to the T helper value was significantly higher in the moderate-severe group compared to the HC group (0.002, 0.026, <0.001, <0.001, 0.027, respectively). Conclusion:Our results suggest that Tregs may have a role in the pathogenesis of TS/CTD

Is parturition-timing machinery related to the number of inhibitor cd94/nkg2a positive uterine natural killer cells?

Purpose: Prematurity is the most common cause of infant mortality and morbidity. To prevent this, the timing of parturition and its mechanisms should be understood. It is likely that inhibitor CD94/NKG2A positive decidual natural killer cells (uNK) provide for the continuation of pregnancy. Here, we aimed to evaluate whether CD94/NKG2A positive uNK cells are highest in elective cesarian section (C/S) (suggesting ongoing gestation), moderate in normal full-term birth, and lowest in pre-eclamptic parturition. Methods: Of 48 pregnant women, 21 C/S, 16 normal, and 11 pre-eclamptic deliveries were included in this study. Five placentas in each group were assigned randomly. After staining, the volumetric analysis of the placental villi and villous blood vessels was performed via the Cavalieri principle. The CD94/NKG2A positive uNK cells were counted using the physical disector method. Results: The gestation periods and birth weights of the pre-eclamptic deliveries were lower than those of the other two groups. Additionally, the villi and villous vascular volumes were lowest in the pre-eclamptic placentas. As proposed in our hypothesis, the inhibitor CD94/NKG2A positive uNK cells were the highest in the C/S, moderate in the normal, and lowest in the pre-eclamptic placentas. Conclusions: These data suggest that CD94/NKG2A positive uNK cells are related with the continuation of pregnancy, and that our human model could be used to search for parturition-timing machinery. We believe that CD94/NKG2A positive uNK cells are also related to the timing of birth

The Efficacy of Long-Term Voriconazole Prophylaxis on Seven Patients with Chronic Granulomatous Disease and Review of the Literature

Objective: Chronic granulomatous disease (CGD) a primary immunodeficiency disease that affects the innate immune system, and characterized by life-threatening and/or recurrent infections caused by bacteria and fungi. Invasive fungal diseases (IFDs) are the most common causes of death among CGD patients. Itraconazole is usually used for prophylaxis in CGD patients at high risk of IFD. However, patient compliance with oral itraconazole use is low due to gastrointestinal side effects. We aim to report the efficacy of long-term voriconazole prophylaxis for IFD on our CGD patients

Hematopoietic Stem Cell Transplantation in Primary Immunodeficiency Patients in the Black Sea Region of Turkey

Hematopoietic stem cell transplantation is a promising curative therapy for many combined primary immunodeficiencies and phagocytic disorders. We retrospectively reviewed pediatric cases of patients diagnosed with primary immunodeficiencies and scheduled for hematopoietic stem cell transplantation. We identified 22 patients (median age, 6 months; age range, 1 month to 10 years) with various diagnoses who received hematopoietic stem cell transplantation. The patient diagnoses included severe combined immunodeficiency (n=11), Chediak-Higashi syndrome (n=2), leukocyte adhesion deficiency (n=2), MHC class 2 deficiency (n=2), chronic granulomatous syndrome (n=2), hemophagocytic lymphohistiocytosis (n=1), Wiskott-Aldrich syndrome (n=1), and Omenn syndrome (n=1). Of the 22 patients, 7 received human leukocyte antigen-matched related hematopoietic stem cell transplantation, 12 received haploidentical hematopoietic stem cell transplantation, and 2 received matched unrelated hematopoietic stem cell transplantation. The results showed that 5 patients had graft failure. Fourteen patients survived, yielding an overall survival rate of 67%. Screening newborn infants for primary immunodeficiency diseases may result in timely administration of hematopoietic stem cell transplantation
