ABSTRACT
BACKGROUND: An increasing incidence of colorectal cancer (CRC) is being reported in developing countries, including India. Most Indian studies on CRC are retrospective and single-centered. The present study is an attempt to understand the current clinical profile and stage of newly diagnosed CRCs across multiple centers in Tamil Nadu, India. METHODS: A multi-centric observational survey was conducted between September 1, 2021, and August 31, 2022, under the aegis of the Indian Society of Gastroenterology - Tamil Nadu chapter. Patients 18 years of age and older with a recent diagnosis of CRC fulfilling the inclusion criteria were prospectively recruited at the participating centers. Their demographic, clinical, biochemical, endoscopic, histopathologic, radiologic and risk factor details were systematically collected and analyzed. RESULTS: Across 23 centers in Tamil Nadu, 1208 patients were recruited. The male:female ratio was 1.49:1, while mean (SD) age was 57.7 (13.5) years. A majority (81.9%) were Tamils and 78.5% belonged to lower socioeconomic classes. The predominant symptoms were hematochezia (30.2%) and a change in bowel habits (27.5%). The most common locations were the rectum (34.3%) and rectosigmoid (15.1%). Synchronous CRCs were seen in 3.3% and synchronous colorectal polyps in 12.8%. Predisposing factors for CRC were seen in 2%. A past history of any cancer among CRC patients was obtained in 3.1% and a family history of any cancer was found in 7.6%. Patients who were either overweight or obese constituted 46.4% of the study population. At presentation, the predominant stages were stage III (44.7%) and stage IV (20.8%). CONCLUSIONS: A majority of patients with newly diagnosed CRC in Tamil Nadu belonged to the lower socioeconomic classes. About 60% had CRCs located within the reach of the flexible sigmoidoscope. Two-thirds of the patients exceeded stage II disease at presentation. TRIAL REGISTRATION: Not applicable.

Objectives: The pivotal of the study was to compare the effectiveness of education in disease-associated knowledge of Inflammatory Bowel Disease (IBD) patients between pre-test and post-test using the IBD-KNOW questionnaire and patient educational resources. Methods: This study used a patient proforma and IBD- KNOW questionnaire to perform the study prospectively by interviewing method. The patient selection was based on inclusion and exclusion criteria by convenient sampling technique from November 2018 to July 2019 at a multispecialty hospital. Knowledge scores and inter-item correlation were calculated between the pre-test and post-test by R Programming software with p<0.05. Results: Among 40 patients with IBD diagnosis, the baseline sociodemographic characteristics were recorded. The response rate of IBD knowledge between the pre-test and post-test resulted in significant differences with varying scales but the response rate was lesser in the domains of management and pregnancy-based questions in the pre-test and post-test. Conclusions: Recently there was a swift in IBD incidence, this may be improved by affording suitable patient education and counseling for further knowledge level in managing the disease by coping strategy. On comparison between the pre-test and post-test, this study recommends innovative educational methods to enable continuing education for chronic disease which can be easily accessible and reliable for IBD patients.

Background: Liver disease is the only major chronic disease and mortality is increasing. Earlier detection of liver fibrosis can reduce progression to cirrhosis and hepatocellular carcinoma. Many studies have reported an increased prevalence in liver fibrosis among adults in urban regions but there are few data in physically active rural populations without attributable metabolic risk factors. This aim of this study is to investigate the prevalence of abnormal liver functions tests (LFTs) and liver fibrosis among adults in a rural population. Methods: This cross-sectional study included observations from KMCH-NNCD-II (2017) study (n = 907) from a farming village, Nallampatti, located in South India. We assessed lifestyle (occupation, tobacco use and alcohol consumption using AUDIT-C questionnaire), markers for metabolic diseases (obesity, hypertension, diabetes, hypercholesterolemia), LFTs and markers for hepatitis viruses B and C. 901 participants had transient elastography to assess fibrosis. Participants with abnormal LFTs and significant liver fibrosis (F2-F4) underwent additional liver screening (caeruloplasmin, iron studies and autoimmune hepatitis panel). Multiple logistic regression analyses were performed to understand the association of liver fibrosis with lifestyle and metabolic risk factors after adjustment for co-variates. Findings: Significant liver fibrosis (F2-F4) was observed in 14.4%, and cirrhosis in 0.8%. There was an association of liver fibrosis with abnormal LFTs but no association between alcohol consumption, viral hepatitis, hepatic liver screening and liver fibrosis. Among metabolic risk factors, no association was observed for hypertension and hypercholesterolemia but diabetes [OR - 3.206 (95% CI: 1.792 - 5.736)], obesity [1.987 (1.341 - 2.944)] and metabolic syndrome [2.539 (1.680 - 3.836)] showed association with significant liver fibrosis (F2-F4) after adjustment for confounding factors. Interpretation: Our results suggest that the prevalence of liver fibrosis in rural population is similar to urban counterparts. The association of metabolic risk factors with liver fibrosis in physically active rural population warrants further investigations in future studies. Funding: This study is funded by KMCH Research Foundation, India.
ABSTRACT
BACKGROUND: Inflammatory bowel disease (IBD) is increasingly diagnosed in South Asia. This survey by the Tamil Nadu Chapter of the Indian Society of Gastroenterology (TNISG) documents the demography, clinical profile, and therapeutic practices related to IBD in Tamil Nadu. METHODS: TNISG members from 32 institutions completed an online cross-sectional questionnaire on IBD patients from March 2020 to January 2021. RESULTS: Of 1295 adult IBD patients, 654 had Crohn's disease (CD), 499 ulcerative colitis (UC), and 42 IBD-unclassified (IBD-U). CD and UC showed a unimodal age distribution. A total of 55% were graduates or postgraduates. A positive family history was noted in 30, other risk factors were uncommon. In CD, the pattern of involvement was ileocolonic (42.8%), ileal (34.7%), colonic (18.9%), and upper gastrointestinal (3.5%); while in UC, disease was characterized as extensive (44.9%), left-sided (41.7%), or proctitis (13.4%). Perineal disease, perianal fistulae, and bowel obstruction were noted in 4.3, 14.0, and 23.5%, respectively, of CD. The most widely used drugs were mesalamine, azathioprine, and corticosteroids. Surgery was undertaken in 141 patients with CD and 23 patients with UC. Of the 138 patients with pediatric IBD (≤16 years), 23 were characterized as very early onset IBD (VEO-IBD), 27 as early-onset, and 88 as adolescent IBD. VEO-IBD were more likely to have a positive family history of IBD and were more likely to have perineal disease and to have the IBD-U phenotype. Among pediatric IBD patients, corticosteroids, mesalamine, and azathioprine were the most commonly used medications, while 25 pediatric patients received biologics. CONCLUSION: This study provides important information on demography, clinical profile, and treatment practices of IBD in India.
ABSTRACT
BACKGROUND AND AIM: Though rodenticidal hepatotoxicity is reported from India, there is no systematic study to assess its magnitude. This study aimed to assess exposure to rodenticide as a risk factor for acute hepatotoxicity in Tamil Nadu, India. METHODS: We retrospectively analyzed acute hepatotoxicity caused by ingestion of hepatotoxin or potentially hepatotoxic drug overdose across 15 hospitals in 6 districts of Tamil Nadu from 1 January 2019 to 30 June 2019. Study exclusion criteria were idiosyncratic drug-induced liver injury and chronic liver diseases. RESULTS: Of the 702 patients, 685 gave history of consuming rodenticide; hepatotoxicity in the other patients resulted from paracetamol overdose (n=10) and due to other drugs (n=7); 97% patients had a suicidal intent. Of 671 patients with complete data, ratio of number of patients with hepatotoxicity due to rodenticide to paracetamol overdose was 450:6 (i.e. 75:1). The 451 rodenticidal hepatotoxicity patients (255 males, 75% were 15-34 years old) underwent conservative management (n=396), plasma exchange (n=54) and plasma exchange followed by liver transplant (n=1); 159 patients (35%) had poor outcome (131 died, 28 discharged in moribund state). Based on our observations, we estimate a case burden of 1584 rodenticidal hepatotoxicity patients (95% CI: 265-6119) with poor outcome in 554 patients in Tamil Nadu from January 2019 to June 2019. Population attributable risk for rodenticide as cause of hepatotoxicity was 22.7%. CONCLUSION: Rodenticide ingestion was an important cause of acute hepatotoxicity in Tamil Nadu. Most patients were young and one-third had poor outcome. Public health interventions are needed to address this.

BACKGROUND: Tubercular lymphadenitis is the commonest extra pulmonary manifestation in cervical and mediastinal locations. Normal characteristics of lymph nodes (LN) have been described on ultrasonography as well as by Endoscopic Ultrasound. Many ultrasonic features have been described for evaluation of mediastinal lymph nodes. The inter and intraobserver agreement of the endosonographic features have not been uniformly established. METHODS AND RESULTS: A total of 266 patients underwent endoscopic ultrasound guided fine needle aspiration and 134 cases were diagnosed as mediastinal tuberculosis. The endoscopic ultrasound location and features of these lymph nodes are described. CONCLUSION: Our series demonstrates the utility of endoscopic ultrasound guided fine needle aspiration as the investigation of choice for diagnosis of mediastinal tuberculosis and also describes various endoscopic ultrasound features of such nodes.
ABSTRACT
BACKGROUND AND AIM: Leptospirosis, endemic in India, is complicated by jaundice and renal failure. Whether leptospirosis could result in a worsening of preexisting chronic liver disease (CLD) is not known. Aim of the study was to analyze the clinical profile and natural course of leptospirosis in decompensated CLD in comparison to those acquiring the infection in an otherwise healthy individual. METHODS: Cases were patients with liver cirrhosis who presented with fever and/or jaundice and were screened and found positive for leptospirosis. Controls were patients diagnosed to have leptospirosis during the same period, but in the absence of liver disease. Both cases and controls were followed up until recovery or death. RESULTS: Thirty-one patients had cirrhosis of the liver, and 91 controls had leptospirosis. Significantly more number of cirrhotics had jaundice (87.1 % vs. 16.5 %; p = 0.001), elevated blood urea (41.9 % vs. 18.7 %; p = 0.01), and serum creatinine (41.9 % vs. 19.8 %; p = 0.03) compared to the controls. There were four deaths due to hepatorenal dysfunction and coagulopathy in cirrhotics and no deaths in the control group (4 vs. 0; p = 0.001). CONCLUSION: Leptospirosis should be considered as yet another important cause of acute-on-chronic liver failure in endemic areas associated with poor outcome. Death is often due to hepatorenal dysfunction.

Chronic hepatitis C infection is an important cause of cirrhosis and hepatocellular carcinoma (HCC). Antiviral therapy (AVT) for patients with cirrhosis due to hepatitis C may retard the progression of cirrhosis and prevent both the development of HCC as well as the recurrence of hepatitis C following liver transplantation. This review highlights the issues associated with AVT for patients with compensated and decompensated cirrhosis due to hepatitis C virus.

BACKGROUND/AIM: Current guidelines recommend screening cirrhotic patients with an endoscopy to detect esophageal varices and to institute prophylactic measures in patients with large esophageal varices. In this study, we aimed at identifying non-endoscopic parameters that could predict the presence and grades of esophageal varices. PATIENTS AND METHODS: In a prospective study, 229 newly diagnosed patients with liver cirrhosis, without a history of variceal bleeding, were included. Demographic, clinical, biochemical and ultrasonographic parameters were recorded. Esophageal varices were classified as small and large, at endoscopy. Univariate analysis and multivariate logistic regression analysis were done to identify independent predictors for the presence and grades of varices. RESULTS: Of the 229 patients (141 males; median age 42 years; range 17-73 years) with liver cirrhosis, 97 (42.3%) had small and 81 (35.4%) had large varices. On multivariate analysis, low platelet count (Odd's Ratio [OR], 4.3; 95% confidence interval [CI], 1.2-14.9), Child Pugh class B/C (OR, 3.3; 95% CI, 1.8-6.3), spleen diameter (OR, 4.3; 95% CI, 1.6-11.9) and portal vein diameter (OR, 2.4; 95% CI, 1.1-5.3) were independent predictors for the presence of varices. Likewise, for the presence of large esophageal varices, low platelet count (OR, 2.7; 95% CI, 1.4-5.2), Child Pugh class B/C (OR, 3.8; 95% CI, 2.3-6.5) and spleen diameter (OR, 3.1; 95% CI, 1.6-6.0) were the independent risk factors. CONCLUSION: The presence and higher grades of varices can be predicted by a low platelet count, Child-Pugh class B/C and spleen diameter. These may be considered as non-endoscopic predictors for the diagnosis and management of large grade varices.

ABSTRACT
BACKGROUND AND AIM: The incidence of peptic ulcer disease has steadily declined throughout the world. The influence of seasonal changes on the incidence of peptic ulcer disease is not well established. The aim of the study was to identify the changing trends in the occurrence of peptic ulcer disease from a tertiary referral center in south India and to study the seasonal Correspondence: variation in the occurrence of peptic ulcer. METHODS: Retrospective analysis of the endoscopic records between the years 1989 to 2004. RESULTS: There was a significant decrease in the endoscopic diagnosis of duodenal and gastric ulcers (DU and GU) over the years. Both duodenal and gastric ulcers were more common in men than women. Over the years, there was a steady increase in the proportion of women affected with both DU and GU. A steady increase in the meanage of endoscopic diagnosis of GU and DU was seen over the years. The adjusted seasonal index revealed an increase in the endoscopic diagnosis of GU and DU in the months October-March. CONCLUSION: The endoscopic diagnosis of DU and GU has shown a decreasing trend over the past 16 years. The adjusted seasonal index has shown an increasing trend between the months of October-March.
