This study aimed to assess the efficacy of 7-day standard tri- Helicobacter pylori ple therapy in patients with CLD including cirrhosis and to investigate the clinical factors influ- eradication encing the success of eradication. A total of 592 H. pylori-infected patients, who received 7- day standard first-line triple therapy between January 1, 2014, and December 31, 2014, were recruited. Patients were divided into two groups: CLD group (N Z 136) and non-CLD group (N Z 456). The eradication rates attained by the CLD and non-CLD groups were 86.0% and 84.2%, respectively, in the per-protocol analysis (p Z 0.606). The eradication rates of liver cirrhosis and noncirrhosis CLD were 88.5% and 84.3%, respectively (p Z 0.783). The adverse events were similar between the two groups (8.8% vs. 9.2%, p Z 0.891). Compliance between the two groups was good (99.3% vs. 99.6%, p Z 0.670). The univariate analysis showed male sex to be the significant clinical factor in the non-CLD group (p Z 0.001) and alcohol consumption to be the significant clinical factor influencing H. pylori eradication rate in patients with CLD (p Z 0.022). Alcohol consumption was the only significant factor influencing H. pylori eradica- tion in multivariate analysis (odds ratio Z 3.786, p Z 0.031). The results of this study suggest that H. pylori eradication rates in patients with CLD may be comparable with non-CLD Conflicts of interest: All authors declare no conflicts of interest. * Corresponding author.

  • Analogy Between Non-Alcoholic Steatohepatitis (NASH) and Hypertension: a Stepwise Patient-Tailored Approach for NASH Treatment
    REVIEW ARTICLE Annals of Gastroenterology (2018) 31, 1-9 Analogy between non-alcoholic steatohepatitis (NASH) and hypertension: a stepwise patient-tailored approach for NASH treatment Yaron Ilan Hadassah Hebrew University Medical Center, Jerusalem, Israel Abstract Non-alcoholic steatohepatitis (NASH) is a common liver disorder worldwide. Although there has been improvement in our understanding of the natural history and pathogenesis of the disease, there is still no approved therapy for NASH. NASH shares many similarities with primary hypertension, in that both are extremely common disorders that can easily lead to serious complications if left untreated. Both conditions are viewed as “silent killers”, because the disease can progress over a period of time prior to the occurrence of potentially deadly outcomes. While attempts to find the “miracle pill” for NASH are unrealistic, we can make an analogy with the “stepwise combination” approach developed over the last few decades for the treatment of hypertension. In the present review, we summarize some of the similarities in the concepts that underlie NASH and hypertension. The development of a stepwise patient-tailored method for the treatment of NASH is presented. Keywords Non-alcoholic steatohepatitis, hypertension, treatment, non-alcoholic fatty liver disease Ann Gastroenterol 2018; 31 (3): 1-9 Introduction Hypertension (HTN) has been recognized for much longer than NASH and the two conditions share many similarities.

  • Gastrointestinal Complications of Diabetes Mellitus
    Diabetes Mellitus: Management of Gastrointestinal Complications BETH CAREYVA, MD, and BRIAN STELLO, MD, Lehigh Valley Health Network/University of South Florida Morsani School of Medicine, Allentown, Pennsylvania Gastrointestinal disorders are common complications of diabetes mellitus and include gastroparesis, nonalcoholic fatty liver disease, gastroesophageal reflux disease, and chronic diarrhea. Symptoms of gastroparesis include early satiety, postprandial fullness, nausea, vomiting of undigested food, bloating, and abdominal pain. Gastroparesis is diagnosed based on clinical symptoms and a delay in gastric emptying in the absence of mechanical obstruction. Gastric empty- ing scintigraphy is the preferred diagnostic test. Treatment involves glucose control, dietary changes, and prokinetic medications when needed. Nonalcoholic fatty liver disease and its more severe variant, nonalcoholic steatohepatitis, are becoming increasingly prevalent in persons with diabetes. Screening for nonalcoholic fatty liver disease is not recom- mended, and most cases are diagnosed when steatosis is found incidentally on imaging or from liver function testing followed by diagnostic ultrasonography. Liver biopsy is the preferred diagnostic test for nonalcoholic steatohepatitis. Clinical scoring systems are being developed that, when used in conjunction with less invasive imaging, can more accu- rately predict which patients have severe fibrosis requiring biopsy. Treatment of nonalcoholic fatty liver disease involves weight loss and improved glycemic control; no medications have been approved for treatment of this condition. Diabe- tes is also a risk factor for gastroesophageal reflux disease. Patients may be asymptomatic or present with atypical symp- toms, including globus sensation and dysphagia. Diabetes also may exacerbate hepatitis C and pancreatitis, resulting in more severe complications. Glycemic control improves or reverses most gastrointestinal complications of diabetes.

  • Non-Alcoholic Fatty Liver Disease from the American Liver
    NAFLD Non-Alcoholic Fatty Liver Disease From the American Liver Foundation www.liverfoundation.org IMPORTANCE The liver is the second largest organ in your body and is located under your rib cage on the right side. It weighs about three pounds and is shaped like a football that is flat on one side. The liver performs many jobs in your body. It processes what you eat and drink into energy and nutrients your body can use. The liver also removes harmful substances from your blood. WHAT IS NAFLD? Non-alcoholic fatty liver disease (NAFLD) is the build up of extra fat in liver cells that is not caused by alcohol. It is normal for the liver to contain some fat. However, if more than 5% - 10% percent of the liver’s weight is fat, then it is called a fatty liver (steatosis). WHO IS LIKELY TO HAVE NAFLD? NAFLD tends to develop in people who are overweight or obese or have diabetes, high cholesterol or high triglycerides. Rapid weight loss and poor eating habits also may lead to NAFLD. However, some people develop NAFLD even if they do not have any risk factors. NAFLD affects up to 25% of people in the United States. Read how Nick Giordano, a marathon runner, was diagnosed with NAFLD. RISKS NAFLD may cause the liver to swell (steatohepatitis). A swollen liver may cause scarring (cirrhosis) over time and may even lead to liver cancer or liver failure. SYMPTOMS NAFLD often has no symptoms. When symptoms occur, they may include fatigue, weakness, weight loss, loss of appetite, nausea, abdominal pain, spider-like blood vessels, yellowing of the skin and eyes (jaundice), itching, fluid build up and swelling of the legs (edema) and abdomen (ascites), and mental confusion.

  • Pancreatic Insufficiency As a Cause of Nonalcoholic Steatohepatitis
    Pancreatic exocrine insufficiency: a rare cause of nonalcoholic steatohepatitis Naoki Tanaka1, Akira Horiuchi2, Takahide Yokoyama3, Shigeyuki Kawa1, and Kendo Kiyosawa1 1Department of Gastroenterology, Shinshu University School of Medicine, Matsumoto, and Department of 2Gastroenterology and 3Surgery, Showa Inan General Hospital, Komagane, Nagano, Japan Correspondence to: Naoki Tanaka, M.D., Ph.D. [email protected] To the Editor: It is well known that nonalcoholic fatty liver disease (NAFLD), including nonalcoholic steatohepatitis (NASH), is usually associated with obesity and metabolic syndrome. We sometimes encounter NASH patients devoid of obesity, but pathogenesis of obesity-unrelated NASH remains unclear. Here we describe the case of non-obese patient with NASH, which is caused by pancreatic exocrine insufficiency. A 73-year-old woman was referred because of abnormal liver function tests. She had been in good health, but had been worried about easy fatiguability and weight loss (4 kg in 3 months). She visited her family practitioner, where routine examination revealed mild elevation of serum aminotransferase levels and hepatic steatosis, so she was referred to our facility. She had not taken alcohol or habitual drugs. Her body weight was 45 kg and body mass index was 21.0 kg/m2. Physical examination showed marked hepatomegaly. Laboratory tests demonstrated mild liver dysfunction: aspartate aminotransferase 96 U/L (normal <38 U/L) and alanine aminotransferase 46 U/L (normal <35 U/L). Serum albumin concentration was decreased (2.8 g/dL; normal 3.8-5.3 g/dL), but her urinalysis and coagulation tests were unremarkable. Viral markers and autoantibodies were negative. An abdominal computed tomography (CT) scan showed massive hepatomegaly and marked decrease in liver parenchyma density (Figure).

  • Oxidative Stress Biomarkers Among Saudi Patients with Non-Alcoholic Steatohepatitis Versus Chronic Hepatitis C
    Eur J Gen Med 2016;13(4):81-85 ISSN:1304-3889 eISSN:1304-3897 Original Article DOI: 10.29333/ejgm/81755 Oxidative stress biomarkers among Saudi patients with non-alcoholic steatohepatitis versus chronic hepatitis C Osama H. Al-Jiffri1 ABSTRACT Objective: As oxidative status may be an influential factor for increasing the progress of the disease and decreasing the effectiveness of the treatment, the aim of this study was to measure the oxidative stress and anti-oxidative markers among Saudi patients with chronic hepatitis C (CHC) versus nonalcoholic steatohepatitis (NASH). Methods: This study was carried out on a sample of 150 consecutive patients (75 with CHC and 75 with NASH), selected from gastroenterology outpatient clinic, King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Also, this study included 75 healthy volunteers, mostly, relatives of the patients who came with them to the clinic. Measurements of oxidative stress and anti-oxidative stress markers were measured for all participants. Results: The mean values of oxidative stress markers included conjugated dienes (CD), malondialdehyde (MDA), nitric oxide (NO) and myeloperoxidase (MPO) were significantly elevated in patients with CHC and patients with NASH when compared with Healthy controls group. Also, these parameters were significantly elevated in patients with NASH than patients with CHC. However, the mean values of anti-oxidative stress markers include glutathione peroxidase (GPx), superoxide dismutase (SOD), glutathione (GSH), arylesterase (AE) and paraoxonase (PON) were significantly reduced in patients with CHC and patients with NASH when compared with Healthy controls group. Also, these parameters were significantly reduced in patients with NASH than patients with CHC.
