BACKGROUND: Celiac disease, as of today, is said to exist in almost all parts of the world, although it is rare among people of purely African-Caribbean, Japanese and Chinese background. The disease has also been considered uncommon in India until recently. Hospital records have revealed an increasing trend of the disease in predominantly wheat-eating areas of North India. The aim of the present study was to determine the prevalence of celiac disease among school children in Punjab, ...

Hepatitis C virus (HCV) genotypes help to tailor the treatment response, but their influence on the disease severity and association with hepatic steatosis is not well understood. The prevalence of HCV genotypes and their correlation with the histopathological severity of liver disease and steatosis in Indian patients were studied. HCV-RNA and genotyping was carried out in 398 patients with chronic hepatitis C. Liver biopsy was available in 292 (73.4%) patients. The severity of liver ...

OBJECTIVES: To study the role of faecal microbiota transplantation [FMT] in maintenance of remission in ulcerative colitis [UC].

METHODS: In this pilot study, patients with UC in clinical remission achieved after multi-session FMT were randomly allocated to either maintenance FMT or placebo colonoscopic infusion every 8 weeks, for 48 weeks. The standard of care [SOC] therapy was continued in all patients. The primary endpoint was maintenance of steroid-free clinical remission [Mayo score ...

INTRODUCTION: Ulcerative colitis occurs worldwide. It is considered common in most of Europe and North America and uncommon in most of the developing Asian countries. The incidence/prevalence of ulcerative colitis varies not only according to geographical region but also with race and ethnicity. There are no reported data from India on the incidence of the disease and its prevalence.

MATERIAL AND METHODS: A house to house survey was conducted by questionnaire, formulated to enquire about ...

BACKGROUND AND AIMS: In chronic hepatitis C virus (HCV) infection with genotype 3, therapy with pegylated interferon (peg-IFN) alfa-2b in a dose of 1.5 mug/kg/week and ribavirin (800-1000 mg/day) is recommended for 24 weeks. Reduced doses of peg-IFN may increase compliance and decrease cost and adverse events. This study aimed to assess the safety and efficacy of two different regimens of peg-IFN alfa-2b, in combination with ribavirin, in genotype 3 patients.

METHODS: A total of 103 ...

BACKGROUND: Three common disease susceptibility variants in the NOD2 gene are associated with inflammatory bowel disease in Caucasians, but not in Asians. Aim To screen for NOD2 variants and examine susceptibility for inflammatory bowel disease in North Indians.

METHODS: A case-control study was carried out in Punjab, India. Confirmed cases of ulcerative colitis and Crohn's disease and healthy controls matched for age (+/-10 years) and ethnicity were studied. Besides genotyping the three ...

The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set up in 2004 on acute-on-chronic liver failure (ACLF) was published in 2009. With international groups volunteering to join, the "APASL ACLF Research Consortium (AARC)" was formed in 2012, which continued to collect prospective ACLF patient data. Based on the prospective data analysis of nearly 1400 patients, the AARC consensus was published in 2014. In the past nearly ...

AIM: To evaluate the role of azathioprine (AZA) in Indian patients with ulcerative colitis over longer duration of time.

METHODS: One hundred fifty six patients with ulcerative colitis who were treated with AZA from January 1995 to December 2003 were reviewed. The indications for its use were as follows: (1) steroid dependent and steroid refractory disease; (2) Azathioprine monotherapy for naive patients with severe disease; and (3) combination therapy (AZA + sulfasalazine or ...

BACKGROUND AND AIM: The introduction of sofosbuvir has revolutionized the treatment of chronic hepatitis C. This study was planned to observe whether the efficacy and tolerability of sofosbuvir-based regimens demonstrated in phase 3 clinical trial results translate into real-life clinical practice.

METHODS: This prospective, non-randomized observational study conducted in Dayanand Medical College and Hospital, Punjab, included all consecutive treatment-naïve patients with chronic ...

Background. The search is on to find more effective drug regimens for patients with severe ulcerative colitis, as conventional drugs such as sulfasalazine and its congeners fail to prevent relapse in a significant number of patients. Azathioprine has also been reported to be useful as a steroid-sparing drug in patients who suffer from frequent relapses. As these drugs when used individually fail to sustain remission in a significant number of patients, we evaluated the combination of ...

Genome-Wide Association studies (GWAS) of both Crohn's Disease (CD) and Ulcerative Colitis (UC) have unearthed over 40 risk conferring variants. Recently, a meta-analysis on UC revealed several loci, most of which were either previously associated with UC or CD susceptibility in populations of European origin. In this study, we attempted to replicate these findings in an ethnically distinct north Indian UC cohort. 648 UC cases and 850 controls were genotyped using Infinium Human ...

OBJECTIVES: Acute insults from viruses, infections, or alcohol are established causes of decompensation leading to acute-on-chronic liver failure (ACLF). Information regarding drugs as triggers of ACLF is lacking. We examined data regarding drugs producing ACLF and analyzed clinical features, laboratory characteristics, outcome, and predictors of mortality in patients with drug-induced ACLF.

METHODS: We identified drugs as precipitants of ACLF among prospective cohort of patients with ...

BACKGROUND & AIMS: Probiotics can maintain ulcerative colitis (UC) in remission effectively, but little is known of their ability to induce remission. We conducted a multicenter, randomized, double-blind, placebo-controlled trial of a high-potency probiotic, VSL#3, for the treatment of mild-to-moderately active UC.

METHODS: Adult patients with mild-to-moderate UC were assigned randomly to groups that were given 3.6 x 10(12) CFU VSL#3 (n = 77) or placebo (n = 70), twice daily for 12 ...

Genotype imputation of the human leukocyte antigen (HLA) region is a cost-effective means to infer classical HLA alleles from inexpensive and dense SNP array data. In the research setting, imputation helps avoid costs for wet lab-based HLA typing and thus renders association analyses of the HLA in large cohorts feasible. Yet, most HLA imputation reference panels target Caucasian ethnicities and multi-ethnic panels are scarce. We compiled a high-quality multi-ethnic reference panel based ...
