Primary Prophylaxis Patterns for Hepatic Encephalopathy in Patients with Liver Cirrhosis: What are the Current Prescribing Trends in Specialty Practice?

INTRODUCTION: Hepatic encephalopathy (HE) is a significant complication of severe chronic liver insufficiency characterized by altered sensorium, motor, and cognitive dysfunction. This was a cross-sectional multicenter, epidemiological study to understand the prescribing pattern for primary prophylaxis of overt HE (OHE) in patients with cirrhosis in India. METHODS: The study was conducted at eight centers across different geographical regions of India. A total of 200 patients (100%) were screened, of which 197 (98.50%) met all the inclusion criteria. The prescribing pattern of the physicians was studied by calculating the percentage (subject to availability of sufficient data) of OHE-naïve patients with cirrhosis who were prescribed with different classes of drugs as primary prophylaxis of HE (such as lactulose, rifaximin, neomycin, sodium benzoate, and L-ornithine L- aspartate). The risk factors responsible for initiation of primary prophylaxis of HE was also determined. RESULTS: All the 197 patients (100%) were prescribed with prophylactic treatment. The factors that were considered by treating physicians to pose a risk for precipitating OHE for which prophylaxis was initiated were constipation in 111 (56.35%), infections in 51 (25.89%) and gastrointestinal bleeding in 35 (17.77%). Of the total 197 patients, 122 (61.93%) patients were prescribed a monotherapy, and 75 (38.07%) were prescribed a combination therapy. Of the patients on combination therapy, 68 (34.52%) patients were prescribed with two primary prophylaxis agents (dual therapy), and seven (3.55%) patients were prescribed with three primary prophylaxis agents (triple therapy). Lactulose was the most commonly prescribed agent for primary prophylaxis, followed by rifaximin. CONCLUSION: These findings may guide recommendations on primary prophylaxis for OHE in patients with liver cirrhosis that may help reduce the occurrence of first episode of overt HE, and thereby prevent subsequent cognitive impairment in these patients.

Indian consensus on gastroesophageal reflux disease in adults: A position statement of the Indian Society of Gastroenterology.

The Indian Society of Gastroenterology developed this evidence-based practice guideline for management of gastroesophageal reflux disease (GERD) in adults. A modified Delphi process was used to develop this consensus containing 58 statements, which were generated by electronic voting iteration as well as face-to-face meeting and review of the supporting literature primarily from India. These statements include 10 on epidemiology, 8 on clinical presentation, 10 on investigations, 23 on treatment (including medical, endoscopic, and surgical modalities), and 7 on complications of GERD. When the proportion of those who voted either to accept completely or with minor reservation was 80% or higher, the statement was regarded as accepted. The prevalence of GERD in India ranges from 7.6% to 30%, being < 10% in most population studies, and higher in cohort studies. The dietary factors associated with GERD include use of spices and non-vegetarian food. Helicobacter pylori is thought to have a negative relation with GERD; H. pylori negative patients have higher grade of symptoms of GERD and esophagitis. Less than 10% of GERD patients in India have erosive esophagitis. In patients with occasional or mild symptoms, antacids and histamine H2 receptor blockers (H2RAs) may be used, and proton pump inhibitors (PPI) should be used in patients with frequent or severe symptoms. Prokinetics have limited proven role in management of GERD.

Indian guidelines on imaging of the small intestine in Crohn's disease: A joint Indian Society of Gastroenterology and Indian Radiology and Imaging Association consensus statement.

The Indian Society of Gastroenterology (ISG) Task Force on Inflammatory Bowel Disease and the Indian Radiological and Imaging Association (IRIA) developed combined ISG-IRIA evidence-based best-practice guidelines for imaging of the small intestine in patients suspected to have or having Crohn's disease. The 29 consensus statements, developed through a modified Delphi process, are intended to serve as reference for teaching, clinical practice, and research.

Chronic hepatitis C virus infection in India: Regional demographics and distribution of viral genotypes.

BACKGROUND AND AIMS: Although chronic hepatitis C virus (HCV) infection affects millions of people in India, few studies have assessed host, viral, and disease characteristics of chronically infected patients at national and regional levels. Such information is critical to support large scale screening and treatment initiatives for chronic HCV infection in India. METHODS: Patients with known chronic HCV infection making routine or for-cause visits to the participating study centers were enrolled in this observational study. Patients attended a single outpatient visit during which demographics and medical history were collected, a physical examination was performed, and blood and urine samples were collected for laboratory assessments. Samples were analyzed to determine HCV genotypes and subtypes, and genotypes of interferon lambda 3 (IFNL3) single nucleotide polymorphism. No therapeutic interventions were administered. RESULTS: We enrolled 500 patients at 19 centers, categorized into four geographic regions (North, South, East, and West). All patients self-identified as Indian, and most (66 %) were male. Genotype 3 was the most common genotype overall (54 %); however, its prevalence varied greatly by region, ranging from 34 % in the South to 69 % in the East. Genotypes 1 (24 %) and 4 (6 %) were the next most common, and HCV genotype could not be determined for 16 % of patients. CONCLUSIONS: This prospective survey suggests that demographics, viral, and host factors in patients with chronic HCV infection are highly variable in India and pose significant challenges for the implementation of broad-scale screening and treatment initiatives.

Comparison of Manning, Rome I, II, and III, and Asian diagnostic criteria: report of the Multicentric Indian Irritable Bowel Syndrome (MIIBS) study.

BACKGROUND: Attempts to diagnose and subtype irritable bowel syndrome (IBS) by symptom-based criteria have limitations, as these are developed in the West and might not be applicable in other populations. OBJECTIVES: This study aimed to compare different criteria for diagnosing and subtyping of IBS in India. METHOD: Manning's and the Rome I, II, and III criteria as well as the Asian criteria were applied to 1,618 patients (from 17 centers in India) with chronic lower gastrointestinal (GI) symptoms with no alarm features and negative investigations. RESULTS: Of 1,618 patients (aged 37.5 [SD 12.6] years; 71.2% male), 1,476 (91.2%), 1,098 (67.9%), 649 (40.1%), 849 (52.5%), and 1,206 (74.5%) fulfilled Manning's, Rome I, II, and III, and the Asian criteria, respectively. The most common reason for not fulfilling the criteria was absence of the following symptoms: "more frequent stools with onset of pain," "loose stool with onset of pain," "relief of pain with passage of stool," "other abdominal discomfort/bloating," and, in a minority, not meeting the duration criterion of 3 months/12 weeks. By stool frequency, constipation-predominant IBS (<3 stools/week) was diagnosed in 319 (19.7%), diarrhea-predominant IBS (>3 stools/day) in 43 (2.7%), and unclassified in 1,256 (77.6%). By Bristol stool form, constipation, diarrhea, and unclassified were diagnosed in 655 (40.5%), 709 (43.8%), and 254 (15.7%) patients, respectively. By their own perception, 462 (28.6%), 541 (33.4%), and 452 (27.9%) patients reported constipation-predominant, diarrhea-predominant, and alternating types, respectively. CONCLUSION: By Manning's and the Asian criteria, a diagnosis of IBS was made frequently among Indian patients with chronic functional lower GI symptoms with no alarm features; the Rome II criteria gave the lowest yield. By the stool frequency criteria, a majority of patients had unclassified pattern, unlike by the stool form and patients' perception of their symptoms.

Survey of inflammatory bowel diseases in India.

INTRODUCTION: Inflammatory bowel disease (IBD), both ulcerative colitis (UC) and Crohn's disease (CD), once thought to be uncommon, is now seen commonly in India. The Indian Society of Gastroenterology (ISG) Task Force on IBD decided to collate data on the clinical spectrum of IBD currently prevailing in India. METHODS: An open call to members of ISG was given through publication of a proforma questionnaire in the Indian Journal of Gastroenterology and the web portal of ISG. The proforma contained questions related with demographic features, family history, risk factors, clinical manifestations and characteristics, course of disease, and pattern of treatment of IBD. RESULTS: Of 1,255 filled questionnaires received, 96 were rejected and 1,159 (92.3 %) were analyzed. This comprised data on 745 (64.3 %) patients with UC, 409 (35.3 %) with CD, and 5 with indeterminate colitis. The median duration of illness was longer in patients with CD (48 months) compared to those with UC (24 months) (p = 0.002). More than one half of patients (UC 51.6 %, CD 56.9 %) had one or more extraintestinal symptoms. A definite family history of IBD was present in 2.9 % (UC 2.3 % and CD 4.6 %; p = 0.12). The extent of disease in UC was pancolitis 42.8 %, left-sided colitis 38.8 %, and proctitis alone in 18.3 %. The extent of disease involvement in CD was both small and large intestine in 39.6 %, colon alone in 31.4 % and small intestine alone in 28.9 %. Stricturing and fistulizing disease were noted in 18.8 % and 4.4 % of patients with CD respectively. Chronic continuous and intermittent disease course were present in 35.5 % and 47.2 % of UC patients respectively, and in 23.1 % and 68.8 % of CD patients. Four percent of patients with UC had undergone colectomy, while 15.2 % of patients with CD underwent surgical intervention. CONCLUSIONS: The present survey provides a reasonable picture of the demographic features and clinical manifestations of Indian patients with IBD, their risk factors, course of disease, and the treatment given to them.

Epidemiological and clinical profile of irritable bowel syndrome in India: report of the Indian Society of Gastroenterology Task Force.

AIMS: To study the profile of irritable bowel syndrome (IBS), and the frequency of such symptoms among the general population, in India. METHODS: In this prospective, multi-center study, data were obtained from 2785 patients with chronic lower gastrointestinal symptoms (complainants) with no alarm feature and negative investigations for organic causes visiting physicians at 30 centers, and from 4500 community subjects (non-complainants), using separate questionnaires. RESULTS: Most complainants were middle-aged (mean age 39.4 years) and male (1891; 68%). The common symptoms were: abdominal pain or discomfort (1958; 70%), abdominal fullness (1951; 70%); subjective feeling of constipation (1404 of 2656; 53%), or diarrhea (1252 of 2656, 47%), incomplete evacuation (2134; 77%), mucus with stools (1506; 54%), straining at stools (1271; 46%), epigastric pain (1364; 49%) and milk intolerance (906; 32%). Median stool frequency was similar in patients who felt they had constipation or those who felt they had diarrhea. Information to subtype symptoms using standard criteria was available in 1301 patients; of these, 507 (39%) had constipation-predominant IBS ( 3 3 stools/day) and 744 (57%) had indeterminate symptoms. Among non-complainants, most subjects reported daily defecation frequency of one (2520 [56%]) or two (1535 [34%]). Among non-complainants, 567 (12.6%) reported abdominal pain, 503 (11%) irregular bowel, 1030 (23%) incomplete evacuation, 167 (4%) mucus and 846 (18%) straining at stools; a combination of abdominal pain or discomfort relieved by defecation, and incomplete evacuation was present in 189/4500 (4.2%) community subjects. CONCLUSIONS: Most patients with IBS in India are middle-aged men, and have a sense of incomplete evacuation and mucus with stools. Abdominal pain or discomfort is frequent but not universal. Importantly, stool frequency was similar irrespective of whether the patients felt having constipation or diarrhea. Most (90%) non-complainant subjects had 1 or 2 stools per day; symptoms complex suggestive of IBS was present in 4.2% of community subjects.
