Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease. The vitamin D receptor (VDR) gene is a candidate gene for susceptibility to autoimmune disorders. To date, only a few studies concerned the association of the VDR gene polymorphisms with childhood-onset SLE.In this study, we aimed to investigate the BsmI polymorphisms in the VDR gene, for the first time in Egyptian children and adolescents with SLE, to determine whether this polymorphism could be a marker of susceptibility to or severity of SLE and we also measured the serum level of 25-hydroxyvitamin D (25[OH] D) to assess its relation to such polymorphism.This was a case–control study including 100 patients with SLE and matched with age, sex, and ethnicity and 100 healthy controls. All subjects were genotyped for the VDR gene BsmI polymorphism by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), whereas the serum 25(OH) D levels were measured by enzyme-linked immunosorbent assay method.Compared to the contros subjects, the VDR BsmI BB genotype and B allele were overrepresented among SLE patients (odda ratio [OR]: 5.5; 95% confidence interval [CI]: 1.9–15.9; P = 0.002 and OR: 1.84; 95% CI: 1.21–2.80; P = 0.003; respectively). We found a significant association between VDR BsmI BB genotype with lupus nephritis (OR: 6.8; 95% CI: 1.18–50.5; P = 0.001). However, we did not observe any significant association of studied polymorphisms with other clinical manifestations, laboratory profiles of SLE, or disease activity score. Our data revealed no association between VDR BsmI genotypes or alleles and serum 25-hydroxyvitamin D levels among studied patients with SLE (all P > 0.05).We demonstrate for the first time, to the best of our knowledge, that the VDR BsmI gene polymorphisms may contribute to susceptibility to SLE in Egyptian children and adolescents. Moreover, we found that the BB genotype constituted a risk factor for the development of nephropathy among studied patients with SLE. However, we did not find any significant association of the VDR BsmI gene variants with other clinical manifestations, laboratory profiles of SLE, disease activity index score, or serum 25-hydroxyvitamin D levels.

Early diagnosis of non-small cell lung cancer (NSCLC) is essential for patient treatment and prognosis. Long noncoding RNA (lncRNA) have potential roles in tumor initiation and differentiation. The objective of this study was to investigate whether the circulating lncRNA, growth arrest-specific transcript 5 (GAS5) and SOX2 overlapping transcript (SOX2OT), could be used as noninvasive biomarkers for NSCLC diagnosis. Moreover, we aimed at evaluating the association between lncRNA and the clinicopathological features of NSCLC in order to predict the cancer prognosis. The results showed significant downregulation of GAS5 expression and upregulation of SOX2OT in NSCLC patients compared with controls (P < 0.001). Furthermore, the expression level of GAS5 was declined in stage IV of NSCLC, but SOX2OT expression was increased sharply in stages III and IV. The expression levels of lncRNAs were used to distinguish NSCLC patients from control with an area under curve of 0.81 (sensitivity 82.5% and specificity 80%) for GAS5 and 0.73 (sensitivity 76.3% and specificity 78.6%) for SOX2OT. The combination of GAS5 and SOX2OT showed differentiation NSCLC patients from controls with increased sensitivity (83.8) and specificity (81.4). In conclusion, the newly developed diagnostic panel involving of circulating GAS5 and SOX2OT could be perfect biomarker for diagnosis and prognosis of

Diabetes mellitus has been suggested to be the most common metabolic disorder associated with magnesium deficiency, having 25% to 39% prevalence. This deficit could be associated with the development of late diabetic complications, especially macroangiopathy.We aimed to evaluate the status of serum Mg in children with type 1 diabetes and assess its relation to glycemic control and lipid profile.We included 71 Egyptian children with type 1diabetes having their follow-up at Pediatric Endocrinology outpatient clinic, Zagazig University Hospital and 71 age- and sex-matched control. We measured Serum magnesium, HbA1c, and lipid profile in all study subjects.Diabetic children had significantly lower serum magnesium level compared to control children (1.83 ± .27 mg/dL in diabetic children versus 2.00 ± .16 mg/dL in control children). Taking cut-off level of serum magnesium <1.7 mg/dL for definition of hypomagnesemia, hypomagnesemia was detected in 28.2% of diabetic children compared to 9.9% of control children. In diabetic patients, there was statistically significant difference in HbA1c between hypomagnesemic and normomagnesemic group being higher in the low magnesium group, as it is mean ± SD was 11.93 ± 3.17 mg/dL in group I versus 8.92 ± 0.93 mg/dL in the normomagnesemic group. Serum magnesium was found to be positively correlated with HDL (P < 0.001), and negatively correlated with age, HbA1c, triglycerides, total cholesterol, LDL, and duration of diabetes (P < 0.001).We concluded that total serum magnesium was frequently low in Egyptian children with type 1 diabetes and it is correlated with HbA1c and with lipid profile. Hypomagnesemia was more evident in patients with poor diabetic control and those with higher atherogenic lipid parameters. We suggest that low serum magnesium may be included in pathogenesis of poor glycemic control and abnormal lipid profile in children with type 1 diabetes. We need to perform further studies on giving magnesium supplements in diabetic children with hypomagnesemia to observe the effect of correction of serum magnesium on glycemic control, lipid profile, and the risk of diabetic complications.

Introduction. Early diagnosis and treatment of neonatal sepsis may help decrease neonatal mortality. Aim of the Study. To evaluate the role of pancreatic stone protein as a marker for early onset neonatal sepsis. Methods. A hospital-based prospective study was conducted on 104 (52 uninfected and 52 infected neonates) admitted to the Neonatal Intensive Care Unit (NICU) of Zagazig University hospitals during the period from April 2014 to April 2015. All newborns were subjected to full history taking, careful neonatal assessment, blood, C-reactive protein (CRP), and serum pancreatic stone protein. Results. Serum PSP levels were significantly higher in the infected group than in the uninfected group. At a cutoff level of PSP 12.96 ng/mL, the sensitivity was 96.2%, the specificity was 88.5%, positive predictive value was 95.8%, negative predictive value was 89.3%, and area under the curve was 0.87. A significant positive correlation between CRP and PSP was found in infected group. Conclusion. The high negative predictive value of PSP (89.3%) indicates that the serum PSP level is a good marker for diagnosis of early onset neonatal sepsis and can be used to limit hospital stay and antibiotic use in neonates treated for suspected sepsis.

Introduction Despite the presence of a prognostic risk stratification sco-ring system for Hodgkin lymphoma (HL), the lymphocyte-to-monocyte ratio (LMR) is a simple and low-cost test that has been investigated as a prognostic marker to evaluate the clinical course and survival outcomes. Material and methods We prospectively enrolled 92 patients with classical HL (CHL), who were diagnosed and treated in the period from April 2017 to April 2020. Lymphocyte monocyte ratio cut-off values were estimated using receiver operating characteristic curves. Results We found that patients with LMR < 1.4 at the time of diagnosis had poorer progression-free survival (PFS) and overall survival (OS) than those with LMR > 1.4. Patients with increased LMR values after the first 2 cycles of chemotherapy had better PFS and OS; meanwhile, patients who had low LMR after the end of chemotherapy had poorer PFS and OS in comparison to patients who gained higher value after the completion of all cycles of chemotherapy. Conclusions A rise of LMR value indicated better outcome and better survival rate, so it can be an independent prognostic factor for survival and to predict outcome in patients with CHL.

Background: The incidence rate of anemia of chronic disease (ACD) in systemic lupus erythematosus (SLE) ranges between 30 and 80%. Serum iron is the main regulator of hepatic hepcidin production. Interleukin-6 (IL-6) upregulates hepcidin expression. The aim of this study is to compare between serum hepcidin and IL-6 in SLE patients and control subjects, and to find out if they are correlated with each other and with disease activity in order to find their role in treatment of anemia in SLE patients. The study was carried out on 50 SLE patients, suffering from anemia, diagnosed according to SLICC revision of the ACR classification criteria for SLE, and 50 healthy individuals, taken as control. Disease activity was assessed using the SLE disease activity index (SLEDAI-2 K). Serum hepcidin and IL-6 were measured by ELISA kit. Results: There was a highly statistically significant difference in serum hepcidin and IL-6 levels between patients and control subjects. There was a statistically significant correlation between serum hepcidin and IL-6 in SLE patients. Moreover, both of them were correlated with SLEDAI and ESR and negatively correlated with hemoglobin. The mean value of serum hepcidin in SLE patients with normocytic normochromic anemia was higher than that in patients with microcytic hypochromic anemia. However, this difference did not reach a statistically significant level. Conclusion: High serum IL-6 and hepcidin levels are associated with anemia in SLE. They are correlated with each other and with disease activity. Although our study revealed serum hepcidin to be correlated with disease activity, it should not be used as a marker of disease activity in SLE patients as our patient's group was SLE patients suffering from ACD. However, IL-6 inhibition should be considered in patients with SLE with anemia to guide the control of anemia of chronic diseases resulting from cytokine production as a result of high disease activity in SLE patients. It should be noted that the occurrence of ACD associated with IL-6 flare up could be a player in other systemic rheumatic diseases and is not specific to SLE patients.
