IntroductionHepatocellular Carcinoma (HCC) is a primary tumor of the liver; it is one of the most common cancers worldwide. Osteopontin (OPN) is a phosphorylated glycoprotein which is implicated in enhancing invasive and metastatic progression of many tumors. Midkine (MDK) is a 13-kDa small heparin-binding growth factor which plays a significant role in carcinogenesis related activities. The aim of this study was to assess the efficacy of serum Midkine and Osteopontin levels as diagnostic biomarkers of Hepatocellular Carcinoma.MethodsThis study was carried out from January 2014 to January 2016 in Internal Medicine, Clinical Oncology and Tropical Medicine Departments of Tanta University Hospital (Egypt). One hundred forty subjects were enrolled in our study, they were divided into four groups: Group I included 35 patients presented with HCV without cirrhosis; Group II included 35 patients presented with HCV with liver cirrhosis; Group III included 35 patients presented with HCC on top of cirrhosis; and Group IV included 35 apparently healthy subjects as a control group. The studied groups were age and sex matched. Routine and specific (OPN and MDK) laboratory investigations were performed in all included subjects.ResultsThe main finding of the present work was that the mean serum levels of OPN and MDK were significantly elevated in HCC patients either by comparing HCC patients vs. HCV patients without cirrhosis, HCC patients vs. HCV patients with cirrhosis or HCC patients vs. healthy subjects. Interestingly, by performing a ROC analysis, serum MDK levels had better sensitivity and specificity than OPN and AFP levels in the diagnosis of HCC (98.4 %, 97.1% and 97%) and (96.2%, 95.3% and 95%) for MDK, OPN and AFP respectively.ConclusionSerum MDK and OPN levels are comparable to AFP levels and could be used as potential diagnostic biomarkers of HCC in HCV patients with liver cirrhosis and in the prediction of liver cirrhosis in HCV patients without cirrhosis.
Introduction: Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and/or pulmonary embolism (PE), is a common, acute, multifactorial disease with a five-years cumulative incidence of recurrence of approximately 25%. Actually, no single genetic defect can predict the risk of recurrence of VTE. Therefore, individual genetic risk profiling could be useful for the prediction of VTE recurrence. Aim of the study: To assess the combined effect of the common prothrombotic genotypes on the risk of recurrence of VTE in recently diagnosed unprovoked VTE patients. Patients and methods: This population based, prospective follow-up study was carried out from January 2015 to December 2020 in (internal medicine, cardiovascular medicine and anesthesia and ICU departments, Tanta University Hospital, Egypt) on 224 recently diagnosed unprovoked VTE patients. Whole blood was collected by standard venipuncture at the time of admission prior to the beginning of anticoagulant therapy. Genomic DNA was extracted and was genotyped for the 5-SNPs Genetic risk score (GRS), previously validated for first venous thrombosis (FVL rs6025, PTM rs1799963, ABO rs8176719, FGG rs2066865 and FXI rs2036914). Results: The main important finding in the present study was that patients having ≥3 risk alleles were associated with higher risk of VTE recurrence compared to those having ≤2 risk alleles (the reference group) (HR 2.5, 95% CI 1.48–4.21) (p = 0.001). Patients with GRS ≥ 3 had a significantly shorter time recurrence free survival (43.07 months) compared to the low risk group of patients with GRS (0–2) (p < 0.001). Conclusion: GRS model could be an effective and useful model in risk stratification of VTE patients, and genetic risk profiling of VTE patients could be used for the prediction of recurrence of VTE.
Serum amyloid A and sICAM-1 may be considered as reliable markers for detection of VAP. Combination of serum SAA with CPIS increased the specificity to 100%. Measurement of SAA in patients with VAP also had a good predictive value for nonsurvival in such patients.
Objectives This study aimed to evaluate the potential mitigating effect of fisetin on monosodium glutamate (MSG)-induced testicular toxicity and investigate the possible involvement of silent mating type information regulation 2 homolog 1 (SIRT1) in this effect. Methods Forty male rats were divided into normal control, fisetin-treated, MSG-treated, and fisetin + MSG-treated groups. Testosterone, GnRH, FSH, and LH were measured in plasma, as well as SIRT1 and phosphorylated AMP-activated protein kinase (pAMPK) levels in testicular tissues using ELISA. Hydrogen peroxide (H 2 O 2 ), nitric oxide (NO), and reduced glutathione (GSH) were measured colorimetrically, while Nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4) expression was relatively quantified using RT–PCR in testicular tissues. Results After 30 days, fisetin could ameliorate MSG-induced testicular toxicity by acting centrally on the hypothalamic-pituitary-gonadal axis, increasing plasma levels of GnRH, FSH, LH, and testosterone. Peripheral actions of fisetin on the testis were indicated as it increased testicular SIRT1 and pAMPK. Furthermore, it antagonized glutamate-induced oxidative stress by significantly lowering H 2 O 2 , NO, and relative NOX4 expression while significantly increasing reduced GSH levels. It also improved the architecture of the seminiferous tubules, reduced sperm abnormality, and increased sperm count. Discussion Fisetin ameliorates MSG-induced testicular toxicity via central and peripheral mechanisms making it a promising therapeutic target for male infertility.
