1Circulating micro RNA, mi R-122 and mi R-221 signature in Egyptian patients with chronic hepatitis C related hepatocellular carcinoma显示文摘AIM: To explore the potential usefulness of serum miR-122 and miR-221 as non-invasive diagnostic markers of hepatitis C virus(HCV)-related hepatocellular carcinoma(HCC).METHODS: This prospective study was conducted on 90 adult patients of both sex with HCV-related chronic liver disease and chronic hepatitis C related HCC. In addition to the 10 healthy control individuals, patients were stratified into; interferon-na?ve chronic hepatitis C(CH)(n = 30), post-hepatitis C compensated cirrhosis(LC)(n = 30) and treatment-naive HCC(n = 30). All patients and controls underwent full clinical assessment and laboratory investigations in addition to the evaluation of the level of serum miR NA expression by RT-PCR.RESULTS: There was a significant fold change in serum mi RNA expression in the different patient groups when compared to normal controls; mi R-122 showed significant fold increasing in both CH and HCC and significant fold decrease in LC. On the other hand, mi R-221 showed significant fold elevation in both CH and LC groups and significant fold decrease in HCC group(P = 0.01). Comparing fold changes in miR NAs in HCC group vs non HCC group(CH and Cirrhosis), there was non-significant fold elevation in miR-122(P = 0.21) and significant fold decreasing in miR-221 in HCC vs non-HCC(P = 0.03). ROC curve analysis for miR-221 yielded 87% sensitivity and 40% specificity for the differentiation of HCC patients from non-HCC at a cutoff 1.82. CONCLUSION: Serum miR-221 has a strong potential to serve as one of the novel non-invasive biomarkers of HCC.Hassan El-Garem Ayman Ammer Hany Shehab Olfat Shaker Mohammed Anwer Wafaa El-Akel Heba Omar 2014World Journal of Hepatology2014,6,11:18
2Early diagnostic evaluation of miR-122 and miR-224 as biomarkers for hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC)is one of the common lethal types of tumor all over the world.The lethality of HCC accounts for many reasons.One of them,the lack of reliable diagnostic markers at the early stage,in this context,serum miRNAs became promising diagnostic biomarkers.Herein,we aimed to identify the predictive value of two miRNAs(miR-122 and miR-224)in plasma of patients with HCC preceded by chronic HCV infection.Taqman miRNA assays specific for hsa-miR-122 and hsa-miR-224 were used to assess the expression levels of the chosen miRNAs in plasma samples collected from three groups;40 patients with HCC related to HCV,40 with CHC patients and 20 healthy volunteers.This study revealed that the mean plasma values of miRNA-122 were significantly lower among HCC group when compared to CHC and control groups(P<0.001).Whereas,miR-224 mean plasma values were significantly higher among HCC group when compared to both CHC group and control group.Moreover,it was found that miR-122 can predict development of HCC at cut-off value<0.67(RQ)and(AUC Z 0.98,P<0.001).As regards miR-224,it can predict development of HCC at cut-off value>1.2(RQ)and(AUC Z 0.93,P<0.001),while the accuracy of AFP to diagnose HCC was(AUC:0.619;P Z 0.06).In conclusion,the expression plasma of miR-122 and miR-224 could be used as noninvasive biomarkers for the early prediction of developing HCC at the early stage.Khalda S.Amr Hanan Abd Elmawgoud Atia Rehab Abd Elazeem Elbnhawy Wafaa M.Ezzat 2017Genes & Diseases2017,4,4:17
3Diffusion-weighted magnetic resonance imaging and micro-RNA in the diagnosis of hepatic fibrosis in chronic hepatitis C virus显示文摘BACKGROUND Diffusion-weighted magnetic resonance imaging has shown promise in the detection and quantification of hepatic fibrosis. In addition, the liver has numerous endogenous micro-RNAs(miRs) that play important roles in the regulation of biological processes such as cell proliferation and hepatic fibrosis.AIM To assess diffusion-weighted magnetic resonance imaging and miRs in diagnosing and staging hepatic fibrosis in patients with chronic hepatitis C.METHODS This prospective study included 208 patients and 82 age-and sex-matched controls who underwent diffusion-weighted magnetic resonance imaging of the abdomen, miR profiling, and liver biopsy. Pathological scoring was classified according to the METAVIR scoring system. The apparent diffusion coefficient (ADC) and miR were calculated and correlated with pathological scoring.RESULTS The ADC value decreased significantly with the progression of fibrosis, from controls(F0) to patients with early fibrosis(F1 and F2) to those with late fibrosis(F3 and F4)(median 1.92, 1.53, and 1.25 × 10^(-3) mm^2/s, respectively)(P = 0.001).The cut-off ADC value used to differentiate patients from controls was 1.83 × 10^(-3) mm^2/s with an area under the curve(AUC) of 0.992. Combining ADC and miR-200 b revealed the highest AUC(0.995) for differentiating patients from controls with an accuracy of 96.9%. The cut-off ADC used to differentiate early fibrosis from late fibrosis was 1.54 × 10^(-3) mm^2/s with an AUC of 0.866. The combination of ADC and miR-200 b revealed the best AUC(0.925) for differentiating early fibrosis from late fibrosis with an accuracy of 80.2%. The ADC correlated with miR-200 b(r =-0.61, P = 0.001), miR-21(r =-0.62, P = 0.001), and miR-29(r = 0.52,P = 0.001).CONCLUSION Combining ADC and miRs offers an alternative surrogate non-invasive diagnostic tool for diagnosing and staging hepatic fibrosis in patients with chronic hepatitis C.Tarek Besheer Hatem Elalfy Mohamed Abd El-Maksoud Ahmed Abd El-Razek Saher Taman Khaled Zalata Wagdy Elkashef Hossam Zaghloul Heba Elshahawy Doaa Raafat Wafaa Elemshaty Eman Elsayed Abdel-Hady El-Gilany Mahmoud El-Bendary 2019World Journal of Gastroenterology2019,25,11:9
4Clinical asthma phenotyping:A trial for bridging gaps in asthma management显示文摘Asthma is a common disease affecting millions of people worldwide and exerting an enormous strain on health resources in many countries. Evidence is increasing that asthma is unlikely to be a single disease but rather a series of complex, overlapping individual diseases or phenotypes, each defined by its unique interaction between genetic and environmental factors. Asthma phenotypes were initially focused on combinations ofclinical characteristics, but they are now evolving to link pathophysiological mechanism to subtypes of asthma. Better characterization of those phenotypes is expected to be most useful for allocating asthma therapies. This article reviews different published researches in terms of unbiased approaches to phenotype asthma and emphasizes how the phenotyping exercise is an important step towards proper asthma treatment. It is structured into three sections; the heterogeneity of asthma, the impact of asthma heterogeneity on asthma management and different trials for phenotyping asthma.Magdy Mohamed Zedan Wafaa Nabil Laimon Amal Mohamed Osman Mohamed Magdy Zedan 2015World Journal of Clinical Pediatrics2015,4,2:5
5Chronic permanent hypoxemia predisposes to mild elevation of liver stiffness显示文摘AIM:To evaluate the impact of long term permanent hypoxemia noticed in patients with non operated congenital cyanogenic cyanotic cardiopathy on liver stiffness.METHODS:We included ten adult patients with non operated inoperate cyanotic cardiopathy and ten matched patients for age and gender admitted to the gastroenterology department for proctologic diseases;Clinical and laboratory data were collected[age,gender,body mass index,oxygen saturation,glutamate oxaloacetate transaminase(GOT),glutamate pyruvate transaminase(GPT),glycemia and cholesterol].Measurement of hepatic stiffness by transient elastography was carried out in all patients using the Fibroscan device.All patients underwent an echocardiography to eliminate congestive heart failure.RESULTS:Among the patients with cyanotic cardiopathy,median liver stiffness 5.9±1.3 kPa was greater than control group(4.7±0.4 kPa)(P=0.008).Median levels of GOT,GPT,gamma-glutamyltransferase,glycemia and cholesterol were comparable in cardiopathy and control group.In regression analysis including age,gender,body mass index,oxygen saturation,GOT,GPT,glycemia,cholesterol showed that only oxygen saturation was related to liver stiffness(r=-0.63 P=0.002).CONCLUSION:Chronic permanent hypoxemia can induce mild increase of liver stiffness,but further studies are needed to explore the histological aspects of liver injury induced by chronic permanent hypoxemia.Mohamed Tahiri Abdenasser Drighil Yasmine Jalal Dounia Ghellab Wafaa Hliwa Haddad Fouad Wafaa Badre Ahmad Bellabah Rachida Habbal Rhimou Alaoui 2014World Journal of Gastroenterology2014,20,30:5
6Association between low molecular polypeptide 7 single nucleotide polymorphism and response to therapy in hepatitis C virus infection显示文摘AIM: To investigate the relationship between low molecular polypeptide-7 (LMP-7) gene polymorphism and response to interferon (IFN) therapy in chronic hepatitis C virus (HCV) patients. METHODS: LMP-7 polymorphism at codon 49 with nucleotide substitution from A to C was amplified in 104 chronic HCV patients of genotype 4. The amplicons were digested with restriction endonuclease Bsm I and the produced restriction fragment length polymorphism was analyzed. Patients received IFN + regional blood volume therapy for 48 wk and the frequency of thissingle nucleotide polymorphism (SNP) was statistically correlated with treatment response. The exclusion criteria for these patients were stated by the national health program for treating viral hepatitis. Main exclusion criteria included co-infection with hepatitis B virus or schistosomiasis, thyroid dysfunction, uncontrolled diabetes mellitus, history of long term drug or alcohol intake and autoimmune hepatitis. Multivariate analyses were done to correlate LMP-7 SNP plus several factors such as age, gender, weight, serum alpha-fetoprotein (AFP) and alanine aminotransferase levels, liver activity, fibrosis score and viral load with response to therapy. RESULTS: The data presented in this study clearly demonstrated statistically significant differences between sustained virological response (SVR) (defined as the absence of HCV RNA levels in the patient's sera at least 6 mo after discontinuation of treatment) and non-response (NR) (where HCV RNA levels in the patient's sera never become undetectable for 6 mo during or after treatment). Variables were described as odds ratio with 95%CI. The data were considered significant if P values were ≤ 0.05; highly significant if P < 0.01 and very highly significant if P < 0.001. Current data showed that 91.7% of patients carrying LMP-7 C/C allele were associated with SVR, while the other two genotypes C/A and A/A were associated with NR patients, 83.3% and 64.3% respectively, showing that genotype CC was strongly associated with response to interferon (95%CI: 12.0719-134.6572, P = 0.0001). The majority of parameters recorded in SVR and NR patients included higher values of mean age (P = 0.004), alanine aminotransferase (P = 0.001), AFP (P = 0.001), body weight (P = 0.025), viral load (P = 0.025), higher fibrosis and histological activity index indices among NR vs SVR patients. Also, the multivariate statistical analysis of the different factors of fibro-sis score, liver activity grade, genotypes and alleles of LMP-7 gene polymorphism in responders and NRs of HCV patients in this study showed that HCV patients with A allele had a very highly significant association with the NRs, high fibrosis and higher liver activity, while the C allele had a very highly significant association with the responders, low fibrosis and lower liver activity (95%CI: 3.5800-13.2519, P = 0.0001).CONCLUSION: LMP-7 SNP is a candidate gene that should be considered when designing a mathematical model for predicting response to therapy and disease progression in HCV patients.Moataza H Omran Basma E Fotouh Samar S Youssef Noha E Ibrahim Wael Nabil EL-Sayed M Mahdy Wafaa G Shosha Mostafa K El-Awady 2013World Journal of Hepatology2013,5,3:4
7MTP genetic variants associated with non-alcoholic fatty liver in metabolic syndrome patients显示文摘This study was performed for investigation the relationship between variants of MTP gene polymorphism and the development of NAFLD in patients with and without MS.The study was included 174 NAFLD patients(106 with MS and 68 without MS),and 141 healthy control subjects.The 493 G/T polymorphism of MTP gene was evaluated by PCR-RFLP method.The frequency of MTP TT genotype and T allele were significantly higher in NAFLD patients when compared to healthy controls.Moreover,a significant association in MTP gene polymorphism was observed in NAFLD patients with MS compared to NAFLD patients without MS and controls.Our study suggested that MTP 493 G/T gene polymorphism may act as susceptibility biomarker for NAFLD and MS.Weaam Gouda Esmat Ashour Yehia Shaker Wafaa Ezzat 2017Genes & Diseases2017,4,4:4
8Association of vitamin D receptor gene polymorphism(VDR)with vitamin D deficiency,metabolic and inflammatory markers in Egyptian obese women显示文摘Vitamin D deficiency might contribute to the pathogenesis of metabolic syndrome and could cause immune disturbance.The aim of this study is to analyze the associations between Vitamin D receptor(VDR)gene polymorphism,serum 25-hydroxy vitamin D,metabolic and inflammatory biomarkers in Egyptian obese women.The study included 201 obese women with vitamin D deficiency and 249 obese matched age healthy controls with sufficient vitamin D levels.Their age ranged between 25 and 35 years.Inflammatory biomarkers(interleukin-6 and C-reactive protein)and serum 25(OH)D were measured by enzyme-linked immunosorbent assay.Insulin resistance(IR)was determined by the homeostasis model assessment of insulin resistance(HOMA-IR).Vitamin D receptor(VDR)gene polymorphisms of FokI,ApaI,and TaqI were studied by PCR using the restriction fragment length polymorphism(RFLP)technique.Obese women with vitamin D deficiency had significant higher values of inflammatory and metabolic parameters compared to controls.Multivariable-logistic regression showed associations between 25(OH)D deficiency and metabolic components when comparing cases with controls.Moreover,cases carrying polymorphic alleles showed significant lower levels of serum 25(OH)D and higher HOMA-IR,blood pressure levels and lipid parameters compared to those with the wild type homozygote in obese cases with vitamin D deficiency.Vitamin D deficiency in Egyptian obese women with vitamin D deficiency is associated with abnormal metabolic components and abnormal inflammatory biomarkers.Moreover,VDR polymorphisms play important role in immune and inflammation status.Moushira Zaki Sanaa Kamal Walaa ABasha Eman Youness Wafaa Ezzat Hala El-Bassyouni Khalda Amr 2017Genes & Diseases2017,4,3:3
