New Applications

Acute lymphoblastic leukemia (ALL) and its treatment are associated with endothelial dysfunction (ED) and increased cardiovascular risk in adulthood. There are no data on ED in children after successful treatment of ALL. We aimed to assess new ED in these children using the plethysmographic reactive hyperemia index (RHI) and biomarkers that are known to be related to ED. In all, 22 children (mean 15.6 years), after successful treatment of ALL, and 18 healthy subjects were included in this prospective study. RHI, plasma concentrations of asymmetric dimethyl arginine (ADMA), high-sensitive CRP (hsCRP) and E-selectin were measured in all children. RHI values were significantly lower in ALL patients when compared with healthy controls (p<0.05). hsCRP was significantly increased in ALL patients compared with the control group (p<0.001). E-selectin plasma levels were higher in ALL patients as compared to healthy controls (p=0.05). This is the first study that combines both plethysmographic and biochemical methods to assess ED in ALL survivors. Significantly decreased RHI with elevated plasma concentrations of biochemical markers imply a possible association with premature ED in ALL patients. The combined diagnostic approach seems to be a valuable tool for more accurate detection of ED and preventive cardiovascular management in these patients.

Abstract Recent data suggest that oxidative-antioxidative imbalance may influence cytokine secretion in children with acute lymphoblastic leukemia (ALL). Plasma cytokines concentrations are reported to have an effect on clinical course of the patients with lymphoid malignancies. The aim of the study was analysis of oxidative status (Malonylodialdehyde, MDA) and antioxidant defense (Superoxide dismutase, SOD; glutathione peroxidase, GPX; total antioxidant status, TAS and vitamin E) in peripheral blood and evaluation of plasma concentration of IL-2, IL-4, IL-10 and TNF-alpha in children with acute lymphoblastic leukemia. Material and methods: Study group consisted of 23 newly diagnosed ALL children, including 13 boys and 10 girls, with median age 5 years (range, 0.5–16). Control group consisted of 21 healthy children (11 boys and 7 girls) with median age 7 years (range, 2–17). TAS, SOD, GPX status were estimated using commercially available Randox Laboratories Ltd kits. Vitamin E and MDA plasma concentrations were measured spectrofluorimetrically. Cytokine concentrations were measured by quantitative immunoassay tests: IL-2 and IL-4 plasma levels were assessed using Bender MedSystems test (Vienna, Austria), IL-10 and TNF-alpha by R&D system tests. All assays were performed twice: on diagnosis and 6 weeks thereafter. Results: GPX activity in study group was significantly higher before and during treatment than in control subjects (1.5-fold, p=0.02 and 2-fold, p=0.0007, respectively). MDA concentrations were higher in ALL group before treatment (1.4-fold, p=0.0001) and 6 weeks thereafter (1.2 fold, p=0.01) than in control group. SOD activity, TAS and vitamin E concentrations did not differ between the groups. IL-10 level was found to be significantly increased on ALL diagnosis, but not during therapy, when compared to control group (2-fold, p=0.02). TNF-alpha level was higher in patients before treatment then during treatment (3-fold, p=0.02) and as compare to the controls (2,5-fold, ns). IL-2 and IL-4 plasma concentrations were comparable in all groups in both time points. There was a correlation in children with ALL after 6 weeks therapy between MDA and IL-10 concentrations (r=0.59, p<0,05) as well as MDA and TNF-alpha concentrations (r=0,58, p<0,05). In control group MDA was correlated with IL-10(r=0.59, p<0.05). Median follow-up of the study group is 23 months, and at that time relapses occurred in 3 out of 23 patients. 2-fold decrease in median GPX were observed in patients, who relapsed afterward,. Median IL-10 plasma concentrations in children, who subsequently relapsed were 4-fold higher at diagnosis and 8-fold higher after 6 weeks of therapy then in patients who are still in remission (despite of achieving complete remission by all study group at 6th week of treatment). Conclusions: Oxidation process in plasma of children with ALL is significantly increased on diagnosis. Pro-oxidative status may contribute to IL-10 and TNF secretion and affect efficacy of treatment.

Background: An increased risk of cardiovascular complications is reported in survivors of childhood acute lymphoblastic leukemia (ALL). Early identification of impaired vascular health may allow for early interventions to improve outcomes. Aim: The study was conducted to assess the endothelial dysfunction in ALL survivors using a new marker, serum endocan, and measurement of the mean common carotid arteries intima media thickness (cIMT). Methods: A case-control study was conducted on 100 childhood ALL survivors (aged 6–18 years), with 80 healthy age and sex-matched children as a control group. Lipid profile, hepatitis markers, and serum ferritin where measured, in addition to the measurement of serum endocan. and cIMT by B-mode high-resolution ultrasonography for all study participants. Results: Triglycerides, total cholesterol, post prandial glucose, and serum ferritin were significantly higher in ALL survivors than controls ( p < 0.05). Dyslipidemia was detected in 6% of ALL survivors. ALL survivors showed statistically higher serum endocan levels (470.41 ± 556.1 ng/l, versus, 225.94 ± 185.2 ng/l, respectively) and increased cIMT levels compared with the control group (0.650 ± 0.129 mm versus 0.320 ± 0.095 mm, respectively) p < 0.05. Serum endocan was positively correlated with cIMT and blood cholesterol. Conclusions: The survivors of childhood ALL demonstrated an elevated level of serum endocan and increased cIMT. These can be used as predictors of endothelial dysfunction, and, as a consequence, the risk of developing premature atherosclerosis.

AbstractOur study aimed to evaluate the levels of MDSCs and Tregs in pediatric B-cell acute lymphoblastic leukemia (B-ALL), their relation to patients’ clinical and laboratory features, and the impact of these cells on the induction response. This study included 31 pediatric B-ALL patients and 27 healthy controls. All patients were treated according to the protocols of the modified St. Jude Children’s Research Hospital total therapy study XIIIB for ALL. Levels of MDSCs and Tregs were analyzed using flow cytometry. We observed a reduction in the levels of CD4 + T-cells and an increase in both the polymorphonuclear MDSCs (PMN-MDSCs) and Tregs. The frequencies of PMN-MDSCs and Tregs were directly related to the levels of peripheral and bone marrow blast cells and CD34 + cells. Complete postinduction remission was associated with reduced percentages of PMN-MDSCs and Tregs, with the level of PMN-MDCs in this subpopulation approaching that of healthy controls. PMN-MDSCs and Tregs jointly play a critical role in maintaining an immune-suppressive state suitable for B-ALL tumor progression. Thereby, they could be independent predictors of B-ALL progress, and finely targeting both PMN-MDSCs and Tregs may be a promising approach for the treatment of B-ALL.

Abstract Purpose: Study was by intention to screen serum autoantibodies that may contribute to the early detection of B-cell acute lymphoblastic leukemia (B-ALL) in children.Patients and methods: The total protein from three pooled B-ALL cell lines(NALM-6, REH and BALL-1 cells) was separated using two-dimensional gel electrophoresis(2-DE), which was followed by Western blot by mixed serum from B-ALL patients (n=20) or healthy children(n=20). We obtained and analyzed the images of 2-D gel and Western blot by PDQuest software,and then identify the spots of immune responses in B-ALL samples compared with those in control samples.The proteins from spots were identified using mass spectrometry (MS). The autoantibodies against α-enolase and voltage-dependent anion-selective channel protein 1(VDAC1) were further validated on the use of enzyme-linked immunosorbent assay(ELISA). The protein expression levels of the candidate antigens α-enolase and VDAC1 in B-ALL were thoroughly studied by immunohistochemical analysis.Results: Six protein dots were identified with MS as Aconitase,apoptosis-inducing factor(AIF),dihydrolipoamide dehydrogenase(DLD), α-enolase,medium-chain acyl-CoA dehydrogenase(MCAD) and VDAC 1.The frequencies of autoantibodies against α-enolase and VDAC1 in children with B-ALL were 27% and 23%, respectively, which were significantly higher than those in normal controls(4% and 0). Immunohistochemical analysis showed the expression of α-enolase and VDAC1 was positive in 95% and 85% of B-ALL patients, respectively, but negative expression levels were showed in the control group. Conclusion: This study incidates that α-enolase and VDAC1 may be the antigen associated with B-ALL .α-enolase and VDAC1 autoantibodies may develop into potential serological markers of B-ALL in children.Other proteins also need to be confirmed in a large number of serum samples.

Introduction: Previous studies in patients with Raynaud’s phenomenon (RP) have found an association between microvascular abnormalities assessed via nail fold capillaroscopy as well as macrovascular peripheral endothelial dysfunction (PED). However, the association between RP and microvascular PED is not yet established. Hypothesis: We hypothesized that patients with RP have greater microvascular PED compared to controls without RP Methods: We performed a retrospective cross-sectional analysis of patients referred to Mayo Clinic between 2006 and 2014 for routine cardiovascular evaluation, and who underwent evaluation of Reactive Hyperemia Peripheral Arterial Tonometry (index < 2 consistent with PED). Patients with RP were identified by chart review. Results: Six hundred sixty six individuals were included in this study (mean age 51.9±13.5 years, 411 (61.3%) women), 637 (95.1%) individuals did not have RP (control group), and 29 (4.3%) had secondary RP. Only 4 patients had primary RP and were excluded from the final analyses. Individuals with secondary RP had a higher frequency of microvascular PED compared to controls ( Figure ). In a multivariate analysis adjusting for age, sex, smoking status, and use of statins we found a significant association between secondary RP and microvascular PED (OR: 2.45; 95% CI 1.13-5.34; P=0.0236) that remained significant in women after stratifying by sex. In a sensitivity analysis, we compared the frequency of PED in 29 patients with secondary RP and 58 controls matched with respect to age, sex, hypertension, dyslipidemia, and diabetes mellitus. Individuals with secondary RP had a higher frequency of microvascular PED compared to the risk factor-matched controls (18/29 [62.1%] vs 18/58 [31.0%], P=0.01). Conclusions: Secondary RP is associated with microvascular PED. Early detection of microvascular PED could help identify individuals with secondary RP who are at risk for developing cardiovascular disease.

AbstractEndothelial dysfunction is the important early step in the development of atherosclerosis. Hypothyroidism caused by Hashimoto’s thyroiditis and other thyroid disease is one of the risk factors of endothelial dysfunction. The present study tried to investigate the endothelial function and its associated factors in Hashimoto thyroiditis with euthyroidism. A total of 95 newly diagnosed Hashimoto’s thyroiditis patients with euthyroidism and 45 healthy controls were studied. Hashimoto’s patients were divided into 3 subgroups namely, single thyroglobulin antibody (TGAb) positive subgroup, single thyroid peroxidase antibody (TPOAb) positive subgroup, and both TGAb and TPOAb positive subgroup. Endothelial function was tested by the reactive hyperemia index (RHI). Hashimoto’s thyroiditis patients had lower RHI than healthy controls (1.73±0.42 vs 1.96±0.51, p<0.05). Hashimoto’s thyroiditis with single TGAb positive patients had higher RHI than single TPOAb positive (1.98±0.57 vs. 1.69±0.33, p<0.05) and TGAB + TPOAb positive patients (1.98±0.57 vs. 1.68±0.42, p<0.05). RHI were negatively associated with total cholesterol (TC, r=−0.215, p<0.05), low density lipoprotein cholesterol (LDL-C, r=−0.268, p<0.05), triglyceride (TG, r=−0.192, p<0.05), and TPOAb (r=−0.288, p<0.05). In the regression analysis, LDL-C (β=−0.146, p<0.05), TG (β=−0.034, p<0.05) and TPOAb (β=−0.001, p<0.05) were independently associated with RHI. Hashimoto’s patients had poor endothelial function. TPOAb levels were negatively associated with endothelial function.
