SPECTRUM OF CELIAC DISEASE AT TERTIARY CARE CENTER OF NORTHEREN INDIA


Authored by Parveen Malhotra

Aim: This study conducted with aims to classify the endoscopic duodenal biopsies using modified Marsh grading in cases of suspected celiac disease and compare these grades with various clinical and serological parameters including serum TtG levels.
Background: Celiac disease (CD), is a chronic immune-mediated disorder of small intestine that occurs in genetically predisposed populations. It is characterized by permanent intolerance to wheat gliadins and other cereal prolamins. The epidemiology of CD has iceberg characteristics¬ with more undiagnosed cases. The pathogenesis entails a T cell‐mediated immune response with production of auto antibodies directed against tissue transglutaminase or endomysium. The diagnosis of CD is currently based on both typical small bowel biopsy findings with clinical and serological parameters.
Materials and Methods: Biopsies from second part of duodenum in total of 100 consecutive cases of suspected CD (on the basis of clinical and serological profile) formed the study group. Histopathological diagnosis was established on routine hematoxylin and eosin stained sections. The histopathological grading was performed as per modified Marsh grading. Representative section was also subjected for immunohistochemically staining with antihuman CD3 antibody for evaluating intraepithelial lymphocytes. Comparison of these grades with the serological (anti tTg levels) and other clinical parameters (symptoms, weight, endoscopy and hemoglobin levels) were done. These data were subsequently analyzed using SPSS 20.0 software. Chi square test and other relevant statistics were used to assess the relationship between two variables. P-value less than 0.05 was accepted as statistically significant.
Results and Conclusions: Majority of patients presented with typical gastrointestinal symptoms and significantly correlated with higher Marsh grades (p= 0.0326) but atypical symptoms can be the primary presentation of the disease. Patients with higher serum anti-tTG levels, have a high-degree probability of duodenal damage. Anti-tTG levels have conclusively been proven to correlate with increasing histological grades (p=0.005). So, in selected conditions with strong clinical suspicion and high titers of anti tTG, a duodenal biopsy may be avoided especially in children and it could be the basis to prescribe a GFD.

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...
