NON-INVASIVE BIOMARKERS VS LIVER BIOPSY IN DIAGNOSING & STAGING NAFLD

Authored by Parveen Malhotra

Introduction: Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of disease ranging from simple steatosis to inflammatory steatohepatitis (NASH) with increasing levels of fibrosis and ultimately cirrhosis. It has been considered the most common liver disease and the most frequent cause of elevated aminotransferases and cryptogenic cirrhosis.
Aims and Objectives: To evaluate the role of non invasive biomarkers and compare them with liver biopsy in diagnosis and staging of Non Alcoholic Fatty Liver Disease
Material and Methods:This study was conducted at Pt. B D Sharma, PGIMS, Rohtak. A total of forty consecutive patients of nonalcoholic fatty liver disease underwent liver biopsy, in addition to non-invasive biomarkers. P value of < 0.05 was taken as significant and < 0.01 as highly significant whereas p value > 0.05 was taken as non-significant.
Results: The patients were in age group of 22-70 years with mean age of 44-35 years. Seventy percent were females and 30% were male. Impaired fasting glucose levels were seen in 37.5% cases, obesity and hypertension was present in 35% and 45% cases respectively. Out of 40 cases, features of definite NASH were seen in 65% cases and 35% cases showed features of probable NASH. Fibrosis stage I was seen in 80% cases, while both stage II and III fibrosis cases were 10% each
ConclusionThe simple noninvasive scoring systems have a role in assessment of fibrosis and can identify patients with NAFLD at higher risk for development of liver related complications and higher overall mortality. The major advantage of using any of these simple scoring systems is that they are derived from readily available clinical and laboratory indices. Furthermore, a combination of these simple noninvasive markers may perform better than each alone. However, this needs to be assessed in future studies with larger sample size.

A Modified Sequential Regimen of Helicobacterpylori Treatment Enforced by Bacillus clausii and Zinc Carnosine Complex Yields High Eradication Rates_Juniper Publishers

  ADVANCED RESEARCH IN GASTROENTEROLOGY & HEPATOLOGY JUNIPER PUBLISHERS   Authored by Dajani AI      Abstract Introduction: Over the past decade a worldwide trend of decline in the cure rates of Helicobacter pylori is observed. Current eradication rates achieved by the standard triple therapy are below 70%. Sequential therapy had provided a potential alternative that would compensate for the unmet performance of triple therapy. Despite its superiority to triple therapy, the excellent results reported initially were not reproduced by other investigators work. Adding adjuvant agents was also found to improve further the success rate of eradication. Probiotics emerged as a useful adjunct in treatment and prophylaxis of Helicobacter pylori infection. The nutritional supplement Zinc carnosine complex is another adjuvant which is believed to add value to the treatment. Patients and method: an open label randomized observational clinical study ...

Association between Nonalcoholic Fatty Liver Disease and Carotid Atherosclerosis-Juniper Publishers

Image
JUNIPER PUBLISHERS-ADVANCED RESEARCH IN GASTROENTEROLOGY & HEPATOLOGY Abstract Aim/Background: Nonalcoholic fatty liver disease (NAFLD) frequently accompanies to the criteria of Metabolic Syndrome (MetS) like obesity, diabetes, and dyslipidemia. It is recently approved as a liver attaint of MetS. While MetS is a highly atherogenic condition we examined whether NAFLD was associated with atherosclerosis, as measured by ultrasound in the carotid arteries. Methods: Carotid intima-media thickness and cardiovascular risk factors were evaluated in 64 patients with an ultrasound diagnosis of primary NAFLD and 64 matched population controls. Metabolic syndrome was established according to WHO and ATP-III criteria. IMT values were evaluated according to protocols of standard measurements of carotid artery. Results: The metabolic syndrome and all its individual features were significantly (P<0.001) more frequent in NAFLD patients than in control subjects. P...

Discussion on Liver Preoperative Planning System Based on Deep Learning_Juniper Publishers

Image
      ADVANCED RESEARCH IN GASTROENTEROLOGY & HEPATOLOGY JUNIPER PUBLISHERS     Authored by Nishant Shukla    Abstract Liver cancer has become the second largest cancer death rate in the world, and the prevention and treatment of liver diseases is extremely urgent. It has grown up to be a hot spot and focus of the world. With the development of medical imaging and the introduction of “precise surgery”, the development of preoperative planning system for liver diseases has become a research hotspot. Accurate preoperative planning system relies on the development of image processing technology, and the introduction and application of deep learning just improve the accuracy of image processing technology and promote the development process of liver preoperative planning system. This paper mainly expounds the main problems of today’s deep learning-based liver preoperative planning system and discusses the solution to the problem and th...
