| 1 | Type 2 diabetes mellitus:From a metabolic disorder to an inflammatory condition显示文摘Diabetes mellitus is increasing at an alarming rate and has become a global challenge.Insulin resistance intarget tissues and a relative deficiency of insulin secretion from pancreatic β-cells are the major features of type 2 diabetes(T2D).Chronic low-grade inflammation in T2 D has given an impetus to the field of immuno-metabolism linking inflammation to insulin resistance and β-cell dysfunction.Many factors advocate a causal link between metabolic stress and inflammation.Numerous cellular factors trigger inflammatory signalling cascades,and as a result T2 D is at the moment considered an inflammatory disorder triggered by disordered metabolism.Cellular mechanisms like activation of Tolllike receptors,Endoplasmic Reticulum stress,and inflammasome activation are related to the nutrient excess linking pathogenesis and progression of T2 D with inflammation.This paper aims to systematically review the metabolic profile and role of various inflammatory pathways in T2 D by capturing relevant evidence from various sources.The perspectives include suggestions for the development of therapies involving the shift from metabolic stress to homeostasis that would favour insulin sensitivity and survival of pancreatic β-cells in T2 D. | Iqra Hameed Shariq R Masoodi Shahnaz A Mir Mudasar Nabi Khalid Ghazanfar Bashir A Ganai | 2015 | World Journal of Diabetes2015，6，4： | 36 |
| 2 | Prevalence of gastric varices and results of sclerotherapy with N-butyl 2 cyanoacrylate for controlling acute gastric variceal bleeding显示文摘AIM: To study the prevalence, predictors and control of bleeding following N-butyl 2 cyanoacrylate (NBC) sclerotherapy of gastric varix (GV). METHODS: We analyzed case records of 1436 patients with portal hypertension, who underwent endoscopy during the past five years for variceal screening or upper gastrointestinal (GI) bleeding. Fifty patients with bleeding GV underwent sclerotherapy with a mean of 2 mL NBC for control of bleeding. Outcome parameters were primary hemostasis (bleeding control within the first 48 h), recurrent bleeding (after 48 h of esophago- gastro-duodenoscopy) and in-hospital mortality were analyzed. RESULTS: The prevalence of GV in patients with portal hypertension was 15% (220/1436) and the incidence of bleeding was 22.7% (50/220). Out of the 50 bleeding GV patients, isolated gastric varices (IGV-I) were seen in 22 (44%), gastro-oesophageal varices (GOV) on lesser curvature (GOV-Ⅰ) in 16 (32%), and GOV on greater curvature (GOV-Ⅱ) in 15 (30%). IGV-Ⅰ was seen in 44% (22/50) patients who had bleeding as compared to 23% (39/170) who did not have bleeding (P < 0.003). Primary hemostasis was achieved with NBC in all patients. Re-bleeding occurred in 7 (14%) patients after 48 h of initial sclerotherapy. Secondary hemostasis was achieved with repeat NBC sclerotherapy in 4/7 (57%). Three patients died after repeat sclerotherapy, one during transjugular intrahepatic portosystemic stem shunt (TIPSS), one during surgery and one due to uncontrolled bleeding. Treatment failure-related mortality rate was 6% (3/50). CONCLUSION: GV can be seen in 15% of patients withportal hypertension and the incidence of bleeding is 22.7%. NBC is highly effective in controlling GV bleeding. In hospital mortality of patients with bleeding GV is 6%. | Khalid Mumtaz Shahid Majid Hasnain A Shah Kashif Hameed Ashfaq Ahmed Saeed Hamid Wasim Jafri | 2007 | World Journal of Gastroenterology2007，13，8： | 12 |
| 3 | Hepatitis B genotypes: Relation to clinical outcome in patients with chronic hepatitis B in Saudi Arabia显示文摘AIM: To identify the most common hepatitis B virus (HBV) genotype in Saudi Arabia, and correlate the prevailing genotypes with the clinical outcome of patients. METHODS: Patients were consecutively recruited from the hepatology clinics of two tertiary care referral cen- ters. Patients were categorized into 4 different groups: group 1, patients with hepatitis B and normal liver en- zymes; group 2, patients with hepatitis B and abnormal liver enzymes but without cirrhosis; group 3, patients with hepatitis B and liver cirrhosis; group 4, patients with hepatitis B and hepatocellular carcinoma. All patients had a positive hepatitis B surface antigen (HBsAg). Ge- notyping of HBV was performed by nested PCR-mediated amplification of the target sequence and hybridization with sequence-specific oligonucleotides. RESULTS: Seventy patients were enrolled in this study. They were predominantly male (72.9%) in their mid- forty’s (mean age 47 years). Forty-nine (70%) patients were hepatitis B envelope antigen (HBeAg) negative. The majority of patients (64%) acquired HBV through unknown risk factors. Hepatitis B genotyping revealed that 57 patients (81.4%) were genotype D, 1 patient (1.4%) had genotype A, 1 patient (1.4%) had geno- type C, and 4 patients (5.7%) had genotype E, while 7 patients (10%) had mixed genotype (4 patients ADG, 1 patient DE, 1 patient DF, and 1 patient ADFG). Based on univariate analysis of genotype D patients, significant predictors of advanced liver disease were age, gender, aspartate transaminase, alanine transaminase, albumin,bilirubin, and alkaline phosphatase (all P < 0.001). In multivariate analysis decreased hemoglobin (r = -0.05; 95% CI: -0.08 to -0.03; P = 0.001) and albumin levels (r = -0.004; 95% CI: -0.007 to -0.001; P = 0.002) were highly significant predictors of advanced liver disease. In patients with HBV genotype D, HBeAg negativity was found to increase across advancing stages of liver dis- ease (P = 0.024). CONCLUSION: This study highlights that the vast ma- jority of Saudi patients with chronic hepatitis B have genotype D. No correlation could be observed between the different genotypes and epidemiological or clinical factors. The relationship between genotype D and HBeAg status in terms of disease severity needs to be further elucidated in larger longitudinal studies. | Ayman A Abdo Badr M Al-Jarallah Faisal M Sanai Ahmad S Hersi Khalid Al-Swat Nahla A Azzam Manal Al-Dukhayil Amira Al-Maarik Faleh Z Al-Faleh | 2006 | World Journal of Gastroenterology2006，12，43： | 7 |
| 4 | Six Minute Walk Test to assess functional capacity in chronic liver disease patients显示文摘AIM: To examine the utility of Six Minute Walk Test (6MWT) in patients with chronic liver disease (CLD). METHODS: Two hundred and fifty subjects between the ages of 18 and 80 (mean 47) years performed 6MWT and the Six Minute Walk Distance (6MWD) was measured. RESULTS: The subjects were categorized into four groups. Group A (n = 45) healthy subjects (control); group B (n = 49) chronic hepatitis B patients; group C (n = 54) chronic hepatitis C patients; group D (n = 98) liver cirrhosis patients. The four groups differed in terms of 6MWDs (P < 0.001). The longest distance walked was 421 ± 47 m by group A, then group B (390 ± 53 m), group C (357 ± 72 m) and group D (306 ± 111 m). The 6MWD correlated with age (r = -0.482, P < 0.01), hemoglobin (r = +0.373, P < 0.001) and albumin (r = +0.311, P < 0.001) levels. The Child-Pugh classification was negatively correlated with the 6MWD in cirrhosis (group D) patients (r = -0.328, P < 0.01). At the end of a 12 mo follow-up period, 15 of the 98 cirrhosis patients had died from disease complications. The 6MWD for the surviving cirrhotic patients was longer than for non-survivors (317 ± 101 vs 245 ± 145 m, P = 0.021; 95% CI 11-132). The 6MWD was found to be an independent predictor of survival (P = 0.024). CONCLUSION: 6MWT is a useful tool for assessing physical function in CLD patients. We suggest that 6MWD may serve as a prognostic indicator in patients with liver cirrhosis. | Hatem F Alameri Faisal M Sanai Manal Al Dukhayil Nahla A Azzam Khalid A Al-Swat Ahmad S Hersi Ayman A Abdo | 2007 | World Journal of Gastroenterology2007，13，29： | 5 |
| 5 | Clinical epidemiology of ulcerative colitis in Arabs based on the Montréal classification显示文摘AIM:To determine the clinical,epidemiological and phenotypic characteristics of ulcerative colitis(UC)in Saudi Arabia by studying the largest cohort of Arab UC patients.METHODS:Data from UC patients attending gastroenterology clinics in four tertiary care centers in three cities between September 2009 and September 2013were entered into a validated web-based registry,inflammatory bowel disease information system(IBDIS).The IBDIS database covers numerous aspects of inflammatory bowel disease.Patient characteristics,disease phenotype and behavior,age at diagnosis,course of the disease,and extraintestinal manifestations were recorded.RESULTS:Among 394 UC patients,males comprised51.0%and females 49.0%.According to the Montréal classification of age,the major chunk of our patients belonged to the A2 category for age of diagnosis at17-40 years(68.4%),while 24.2%belonged to the A3category for age of diagnosis at>40 years.According to the same classification,a majority of patients had extensive UC(42.7%),35.3%had left-sided colitis and29.2%had only proctitis.Moreover,51.3%were in remission,16.6%had mild UC,23.4%had moderate UC and 8.6%had severe UC.Frequent relapse occurred in17.4%patients,infrequent relapse in 77%and 4.8%had chronic disease.A majority(85.2%)of patients was steroid responsive.With regard to extraintestinal manifestations,arthritis was present in 16.4%,osteopenia in 31.4%,osteoporosis in 17.1%and cutaneous involvement in 7.0%.CONCLUSION:The majority of UC cases were young people(17-40 years),with a male preponderance.While the disease course was found to be similar to that reported in Western countries,more similarities were found with Asian countries with regards to the extent of the disease and response to steroid therapy. | Othman R Alharbi Nahla A Azzam Ahmed S Almalki Majid A Almadi Khalid A Alswat Nazia Sadaf Abdulrahman M Aljebreen | 2014 | World Journal of Gastroenterology2014，20，46： | 2 |
| 6 | Protective effect of Cardiospermum halicacabum leaf extract on glycoprotein components on STZ-induced hyperglycemic rats显示文摘Objective:To investigate the protective role of Cardiospermum halicacabum(C.halicacabum) leaf extract on glycoprotein metabolism in streptozotocin(STZ)-induced diabetic rats.Methods: Diabetes was induced in male albino Wistar rats by intraperitonial administration of STZ.The C.halicacabum leaf extract(CHE) was administered orally to normal and STZ-diabetic rats for 45 days.The effects of C.halicacabum leaf extract(CHE) on plasma and tissue glycoproteins (hexose,hexosamine,fucose and sialic acid) were determined.Results:The levels of plasma and tissues glycoproteins containing hexose,hexosamine and fucose were significantly increased in STZ-induced diabetic rats.In addition,the level of sialic acid significantly increased in plasma and liver while decreased in kidney of STZ-induced diabetic rats.After administration of CHE to diabetic rats,the metabolic alteration of glycoprotein reverted towards normal levels. Conclusions:The present study indicates that the CHE possesses a protective effect on abnormal glycoprotein metabolism in addition to its antihyperglycemic activity. | Chinnadurai Veeramani Khalid S Al-Numair Mohammed A Alsaif Govindasamy Chandramohan Nouf S Al-Numair Kodukkur Viswanathan Pugalendi | 2012 | Asian Pacific Journal of Tropical Medicine2012，5，12： | 2 |

| 8 | Endoscopic ultrasound-fine needle injection for oncological therapy显示文摘The minimal invasiveness and precision of endoscopicultrasound(EUS) has lead to both its widespread use as a diagnostic and staging modality for gastrointestinal and pancreaticobiliary malignancies, and to its expand-ing role as a therapeutic modality. EUS-guided celiac plexus neurolysis is now a well-accepted modality for palliation of pain in patients with pancreatic cancer. EUS-guided ablation, brachytherapy, fiducial marker placement, and antitumor agent injection have been described as methods of performing minimally invasive oncological therapy. EUS-fine needle injection may be performed as adjunctive, alternative, or palliative treatment. This review summarizes the studies to date that have described these methods. A literature search using the Pub Med/MEDLINE databases was performed. While most published studies to date are limited with disappointing outcomes, the concept of a role of EUS in oncological therapy seems promising. | Jeremy Kaplan Amaara Khalid Natalie Cosgrove Ayesha Soomro Syed Mohsin Mazhar Ali A Siddiqui | 2015 | World Journal of Gastrointestinal Oncology2015，7，12： | 2 |
| 9 | Inter-ethnic marriages and severity of coronary artery disease:A multicenter study of Arabian Gulf States显示文摘AIM To assess the association of inter-ethnic vs intra-ethnic marriage with severity of coronary artery disease(CAD) in men undergoing angiography.METHODS We conducted a prospective multicenter,multi-ethnic,cross sectional observational study at five hospitals in Saudi Arabia and the United Arab Emirates,in which we used logistic regression analysis with and without adjustment for baseline differences. RESULTS Data were collected for 1068 enrolled patients undergoing coronary angiography for clinical indications during the period of April 1^(st),2013 to March 30^(th),2014. Ethnicities of spouses were available only for male patients. Of those enrolled,687 were married men and constituted the cohort for the present analysis. Intra-ethnic marriages were reported in 70% and inter-ethnic marriages in 30%. After adjusting for baseline differences,interethnic marriage was associated with lower odds of having significant CAD [adjusted odds ratio 0.52(95%CI:0.33,0.81)] or multi-vessel disease(MVD) [adjusted odds ratio 0.57(95%CI:0.37,0.86)]. The adjusted association with left main disease showed a similar trend,but was not statistically significant [adjusted odds ratio 0.74(95%CI:0.41,1.32)]. The association between interethnic marriage and the presence of significant CAD and MVD was not modified by number of concurrent wives(P interaction > 0.05 for both).CONCLUSION Among married men undergoing coronary angiography,inter-ethnic,as compared to intra-ethnic,marriage is associated with lower odds of significant CAD and MVD. | Amin Daoulah Salem Al-kaabi Amir Lotfi Mushabab Al-Murayeh S Ali Nasseri Waleed Ahmed Salah N Al-Otaibi Mohamed N Alama Osama E Elkhateeb Amy J Plotkin Majed M Malak Khalid Alshali Mohamed Hamzi Saleh Al Khunein Mohammed Abufayyah Alawi A Alsheikh-Ali | 2017 | World Journal of Cardiology2017，9，4： | 2 |
| 10 | Towards hepatitis C virus elimination:Egyptian experience,achievements and limitations显示文摘Worldwide, more than one million people die each year from hepatitis C virus(HCV) related diseases, and over 300 million people are chronically infected with hepatitis B or C. Egypt used to be on the top of the countries with heavy HCV burden. Some countries are making advances in elimination of HCV, yet multiple factors preventing progress; remain for the majority. These factors include lack of global funding sources for treatment, late diagnosis, poor data, and inadequate screening. Treatment of HCV in Egypt has become one of the top national priorities since 2007. Egypt started a national treatment program intending to provide cure for Egyptian HCV-infected patients. Mass HCV treatment program had started using Pegylated interferon and ribavirin between 2007 and 2014. Yet, with the development of highly-effective direct acting antivirals(DAAs) for HCV, elimination of viral hepatitis has become a real possibility. The Egyptian National Committee for the Control of Viral Hepatitis did its best to provide Egyptian HCV patients with DAAs. Egypt adopted a strategy that represents a model of care that could help other countries with high HCV prevalence rate in their battle against HCV. This review covers the effects of HCV management in Egyptian real life settings and the outcome of different treatment protocols. Also, it deals with the current and future strategies for HCV prevention and screening as well as the challenges facing HCV elimination and the prospect of future eradication of HCV. | Dalia Omran Mohamed Alboraie Rania A Zayed Mohamed-Naguib Wifi Mervat Naguib Mohamed Eltabbakh Mohamed Abdellah Ahmed Fouad Sherief Sahar Maklad Heba Hamdy Eldemellawy Omar Khalid Saad Doaa Mohamed Khamiss Mohamed El Kassas | 2018 | World Journal of Gastroenterology2018，24，38： | 2 |
