Abstract
BACKGROUND Alterations in zinc and copper homeostasis may contribute to seizure susceptibility, development, termination, and response to antiepileptic medications. The current study examined the profile of zinc, copper, and their ratio in childhood epilepsy and its pharmacological variants (pharmacoresistant and pharmacoresponsive). METHODS The study included 100 epileptic children (50 pharmacoresistant and 50 pharmacoresponsive) and 50 healthy, age- and gender-matched controls. History, clinical examination, and assays of serum zinc and copper were performed. Zinc/copper ratio was calculated. RESULTS Serum zinc and the zinc/copper ratio were significantly lower in epileptic children than in controls (p < 0.001). Significantly lower zinc and zinc/copper ratio and higher copper levels were found in children treated with levetiracetam/sodium valproate/oxcarbazepine than those treated with levetiracetam alone or combined with sodium valproate (p < 0.05 for all). Epileptic children, particularly pharmacoresistant, exhibited significant negative correlations between the serum levels of zinc and copper (r = -0.279, p = 0.005, and r = -0.363 and p = 0.010, respectively). At cutoff value of zinc/copper ratio < 1.118 in diagnosing children with epilepsy, it gives a sensitivity of 64% and a specificity of 85% with the AUC = 0.8092. At cutoff value of zinc/copper ratio ≤ 0.7826 in distinguishing pharmacoresistant epilepsy, it produced 52% sensitivity, 64% specificity with AUC = 0.576 Conclusions: Low zinc and high copper levels were associated with childhood epilepsy especially those with pharmacoresistant type and treated with Oxcarbazepine. Zinc/copper ratio might be a potential biomarker in diagnosing childhood epilepsy and to some extent in predicting pharmacoresistant type.

Abstract
Neural tube defects (NTDs) are among the most prevalent and debilitating birth defects with their causes are still unknown, despite mounting evidence that genetic and/or environmental factors may play a role. We aimed to analyze two single nucleotide polymorphisms of methylenetetrahydrofolate reductase (MTHFR) gene, serum folate and vitamin B12 status among a cohort of Egyptian children with NTDs and their mothers. A case-control study has been conducted on 50 Egyptian children with various types of NTDs and their mothers. They were comparable with 50 unrelated healthy, age and sex matched children and their mothers (50) selected as controls. Pediatric and neurosurgical assessments were performed to the included cases. Serum folate and vitamin B12 were measured using ELISA kits. MTHFR 677C

Abstract
Background and aim Gastric carcinomais a frequent neoplasm with poor outcome, and its early detection would improve prognosis. This study was designed to evaluate the possible use of new biomarkers, namely SAA and HMGB1, for early diagnosis of gastric cancer. Methods A total of 100 patients presenting with gastric symptoms were included. All patients underwent upper endoscopic evaluation, histopathological diagnosis and serum CEA, SAA, and HMGB1 measurements. Results Patients were classed endoscopically with neoplastic, inflammatory, and normal-appearing gastric mucosa: 50, 25, and 25 patients, respectively. Histologically, half the patients had chronic gastritis and the remaining cases gastric carcinoma of diffuse (n=28) or intestinal (n=22) type. SAA at cutoff of 18.5 mg/L had the best validity to differentiate gastritis from gastric carcinoma, with AUC, sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) of 0.99, 98%, 100%, 100%, and 98%, respectively, followed by HMGB1 at cutoff of 14.5 pg/μL, with AUC, sensitivity, specificity, PPV, and NPV of 0.91, 70%, 96%, 94.6%, and 76.2%, respectively. Sensitivity, specificity, PPV, and NPV of serum CEA at cutoff of 2.9 ng/mL to differentiate gastritis from gastric carcinoma were 42%, 72%, 60%, and 55.4%, respectively, with AUC of 0.53. Nonetheless, higher serum levels of both SAA and HMGB1 reflected higher tumor grade (P=0.027 and P=0.016, respectively) and advanced tumor stage (P-OBrk-0.001 for both). Conclusion Serum levels of both SAA and HMGB1 could be of great value for early diagnosis of gastric carcinoma, comparable to the diagnostic role of serum CEA, which is not valid for early diagnosis of gastric cancer.

Abstract
Background and aim: DNA repair represents a protective mechanism against cell injury and cancer. 8-hydroxy-deoxyguanosine (8-OHdG) is the main ROS-induced DNA mutation. The current study aimed to evaluate urinary 8-OHdG levels in patients with chronic hepatitis C virus (HCV) and its related hepatocellular (HCC) and correlate its level to XRCC1 rs25487 G/A and OGG1 rs1052133 C/G gene polymorphisms. Materials and methods: Urinary 8-OHdG assays were performed using HPLC technique, and XRCC1 rs25487 G/A and OGG1 rs1052133 C/G gene polymorphisms were analyzed by PCR using confronting two-pair primer method (PCR-CTPP) in 200 subjects allocated into 50 chronic HCV patients, 50 HCV-related HCC patients, and 100 controls. Results: There were significantly increased urinary 8-OHdG levels in HCV-related HCC and chronic HCV patients when compared with the controls (P<0.05 for all). Urinary 8-OHdG was associated with the tumor spread. Regarding, XRCC1 (Arg399Gln), AA (Gln/Gln) genotype and A-allele were more frequent in HCC and chronic HCV patients than in the controls (P<0.05). ORs (95%CI) using the dominant and the recessive genetic models were; 2.1 (1.1–4.1), P=0.032 and 1.9 (1–3.6), P=0.043 respectively. For OGG1 (Ser326Cys), GG (Cys/Cys) genotype and G-allele were increased significantly in chronic HCV and HCC patients compared to the controls (P<0.05). ORs (95%CI) under the dominant and the recessive genetic models were; 2.1 (1.1–4.1), P=0.032 and 1.9 (1–3.8), P=0.049 respectively. Additionally, XRCC1 (AA) and OGG1 (GG) genotypes had significantly increased urinary 8-OHdG levels among patients (P<0.05). Conclusions: XRCC1 (AA) and OGG1 (GG) could be considered as possible genotypic risk factors for HCV- related HCC development which were associated with significantly high urinary 8-hydroxy-deoxyguanosine levels, thus urinary 8-OHdG could be considered as non-invasive marker in follow-up chronic HCV progression into HCC.

Abstract
Purpose: We aimed to examine the possible association role of vitamin D and vitamin D receptor (VDR) single nucleotide polymorphisms (SNPs) in type 1 diabetes mellitus (T1DM) development, glycemic control and complications among a cohort of Egyptian children. Subjects and methods: A prospective case-control study has been conducted on 50 Egyptian children with T1DM who were comparable with 50 controls. Vitamin D and HbA1c were measured. VDR-SNPs [ApaI (rs7975232), TaqI (rs731236) and BsmI (rs1544410)] detection was done by polymerase chain reaction through restriction fragment length polymorphism (PCR-RFLP) technique. Vitamin D supplements were given to the included T1DM children with low vitamin D and reassessments of both HbA1c% and 25(OH)D serum levels were performed in those children three months later. Results: Eighty percent of the included diabetic patients have poor glycemic control. Vitamin D was deficient in 68% and insufficient in 16% of diabetic patients. Significant improvements in both vitamin D and glycemic status among T1DM children, who have low vitamin D and received vitamin D supplementations. There were significantly negative correlations between serum levels of vitamin D with both HbA1c % (r= -0.358, P˂0.05) and daily insulin dose (r=-0.473, P˂0.05). Compared with controls, T1DM children presented more commonly with ApaI a allele (OR: 2.87; 95%CI: 1.39-5.91, P˂0.05) and BsmI b allele (OR: 4.38; 95%CI: 2.30-8.33, P˂0.05). TaqI t allele wasn't significantly differing among patients and controls (P˃0.05). Aa+aa and Bb+bb genotypes were significantly higher among T1DM vs the controls (OR: 3.08;, 95%CI: 1.33-7.15, P˂0.05 and OR: 9.33; 95%CI: 3.61-24.17, P˂0.05respectively). Conclusion: ApaI and BsmI were associated with risk of T1DM development among Egyptian children. Low vitamin D status was frequently occurring among T1DM with significant improvement in the glycemic control of such children when adding vitamin D supplements to the standard insulin therapy.

Abstract
Febrile seizures (FS) are frequent convulsive disorders, occurring in infants and young children. The present study aims to assess and compare the serum levels of oxidative stress markers and some essential trace minerals in FS with normal or abnormal EEG and evaluate the effect of antioxidant therapy on the clinical outcome. This study has been carried out on 80 children with FS (40 with simple FS and 40 with complex FS) and 40 febrile children without seizures. Clinical and EEG findings were recorded for the included patients. Biochemical assays of serum nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase (SOD), copper (Cu), zinc (Zn) and selenium (Se), using colorimetric methods, were measured in the studied groups. The overall results showed an increased values of NO, MDA and Cu with decreased values of SOD, Zn and Se in patients with FS (simple and complex) in comparison with febrile children without seizures (p < 0.05 for all). Additionally, NO and MDA was increased in complex FS patients with EEG abnormalities in comparison with complex FS with normal EEG findings (p < 0.05); NO and MDA were also significantly decreased after valproate therapy in complex FS patients (p < 0.05 for all). In conclusions, oxidative stress, decreased Zn and Se with increased Cu may play a role in FS. Valproate improves the oxidative stress status in complex FS.

Abstract
BACKGROUND AND AIMS Hepatitis C virus (HCV) infection is associated with extrahepatic manifestations such as cryoglobulinemia and accounts for up to 90% of all cases of mixed cryoglobulinemia (MC). The present study aimed to evaluate the effect of sofosbuvir-daclatasvir therapy on symptomatic HCV-related MC and sustained virologic response (SVR) achievement. PATIENTS AND METHODS This prospective cohort study was carried out on 120 patients with chronic HCV infection, clinically suspected to have MC, but only 63 of whom were positive for cryoglobulins. HCV-MC patients were treated with sofosbuvir 400 mg and daclatasvir 60 mg once daily for 3 months. The serum cryoglobulins levels, complement 3 (C3), complement 4 (C4) (using ELISA assay kits) and rheumatoid factor (RF) (using immunoturbidimetric assay kit), were measured in the included HCV infected patients (to confirm HCV-MC diagnosis), in addition to quantitave HCV-RNA assays, using real time PCR. All these measurements have been done before stating therapy and 12, 24 weeks post-therapy for assessments of immunological recovery, viral load and SVR. RESULTS Significant increase in the serum cryoglobulin levels and RF with significant decrease in C3 and C4 serum levels were detected in only 63 out of 120 included HCV infected patients, upon whom the study has been completed. They showed significant decrease in their mean cryoglobulin levels from 41.47 µg/mL ±12.32 SD to 5.12 µg/mL ±3.59 SD then to 5.09 µg/mL ±3.02 SD, 12 to 24 weeks post-therapy respectively (p<0.001), with significant decline in RF concentrations and rise in C3 and C4 serum levels approaching the normal values. There were improvements in the presenting HCV-MC clinical manifestations in variable degrees, ranging from 5 (71.42%) in patients with glomerulonephritis to 62 (98.4%) in patients with purpura. Eighty-seven percent of the included patients showed complete response (clinical, virological and immunological recovery) and 13% showed partial response (virological and immunological recovery without clinical improvement of cryoglobulinemia associated manifestations). CONCLUSION A combined therapy of sofosbuvir 400 mg and daclatasvir 60 mg once daily for 3 months was associated with a significant decrease in serum cryoglobulin levels and appears as a reasonable treatment option for HCV-associated MC.
