RESUMO

The Indian Society of Gastroenterology (ISG) felt the need to organize a consensus on Helicobacter pylori (H. pylori) infection and to update the current management of H. pylori infection; hence, ISG constituted the ISG's Task Force on Helicobacter pylori. The Task Force on H. pylori undertook an exercise to produce consensus statements on H. pylori infection. Twenty-five experts from different parts of India, including gastroenterologists, pathologists, surgeons, epidemiologists, pediatricians, and microbiologists participated in the meeting. The participants were allocated to one of following sections for the meeting: Epidemiology of H. pylori infection in India and H. pylori associated conditions; diagnosis; treatment and retreatment; H. pylori and gastric cancer, and H. pylori prevention/public health. Each group reviewed all published literature on H. pylori infection with special reference to the Indian scenario and prepared appropriate statements on different aspects for voting and consensus development. This consensus, which was produced through a modified Delphi process including two rounds of face-to-face meetings, reflects our current understanding and recommendations for the diagnosis and management of H. pylori infection. These consensus should serve as a reference for not only guiding treatment of H. pylori infection but also to guide future research on the subject.

RESUMO

BACKGROUND/AIMS: This study aimed to study the endoscopic yield, appropriateness, and complications of pediatric endoscopy performed by adult gastroenterologists in an adult endoscopic suite. METHODS: This a retrospective study in which records of all the patients less than 18 years of age who underwent endoscopy in the last 5 years were studied. The indications of endoscopy in children were categorized as appropriate or inappropriate per the latest guidelines by American Society for Gastrointestinal Endoscopy and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition. Positive endoscopic yield was defined as the presence of any abnormality on endoscopy. RESULTS: Among the total of 822 children (age <18 years), the most common indications were variceal surveillance/eradication in 157 (19.1%), followed by dyspepsia in 143 (17.4%), upper gastrointestinal (UGI) bleeding in 136 (16.5%), recurrent abdominal pain in 94 (11.4%), unexplained anemia in 74 (9%), recurrent vomiting in 50 (6.08%), chronic refractory gastroesophageal reflux disease in 34 (4.1%) and others; 780 out of 822 endoscopic procedures (94.9%) done in children were appropriate as per the guidelines. The endoscopic yield was 45.8%, highest in patients with UGI bleeding (71.3%), followed by variceal surveillance (54.8%), recurrent vomiting (38%), dyspepsia (37.8%), and recurrent abdominal pain (36%). Minor adverse events occurred in 7.3% of children. CONCLUSION: Pediatric endoscopy performed by an experienced adult gastroenterologist may be acceptable if done in cooperation with a pediatrician.

RESUMO

BACKGROUND: Hepatorenal syndrome (HRS) occurs in decompensated liver disease and carries high mortality. Vasoconstrictors are the drug of choice. Terlipressin is widely used and is expensive. In this study, we compared noradrenaline and terlipressin in the management of type 1 HRS. METHODS: Sixty consecutive patients with type 1 HRS were managed with noradrenaline (Group A, n = 30) or terlipressin (Group B, n = 30) with albumin in a randomized controlled trial at a tertiary center. RESULTS: Reversal of type 1 HRS was achieved in 16 (53%) patients in group A and 17 (57%) in group B. There was statistically insignificant difference between the two groups in decreasing serum creatinine and increasing urine output (p > 0.05). On univariate analysis, Child-Turcotte-Pugh (CTP) score, serum sodium, serum urea, serum albumin, prothrombin time, International normalized ratio (INR), serum alanine aminotransferase (ALT), ascitic fluid protein, and history of bleeding were associated with response to treatment (noradrenaline/terlipressin). However, on multivariate analysis, only baseline CTP score, serum urea, serum albumin, and prothrombin time were independent predictors of response. All patients who responded were discharged alive with no mortality within 30 days. CONCLUSIONS: There is no difference in outcome of patients with type 1 HRS treated with noradrenaline or terlipressin. Thus, noradrenaline, which is cheaper, can be used instead of terlipressin (Clinical Trials Registry-India [CTRI] No. CTRI/2011/09/002032).

RESUMO

Background: Helicobacter pylori infection is recognised as type 1 carcinogen by the International Agency of Research on Cancer. Previous studies in our hospital have revealed high prevalence of H. pylori in our population with a high recurrence rate after completion of treatment. This prompted us to undertake this study. Aim: This study aimed to determine common gene mutations leading to resistance to clarithromycin, metronidazole, tetracycline and quinolones in H. pylori in patients attending our hospital. Settings and Design: This is a cross-sectional hospital-based study. The study was approved by the Institutional Ethics Committee. Materials and Methods: This study was conducted on 196 adult dyspeptic patients with an indication for upper gastrointestinal endoscopy. Gastric biopsies collected from them were subjected to histopathological examination, rapid urease test (RUT) and culture. Of the 196 patients, 95 met the inclusion criteria. Drug susceptibility testing (DST) by various polymerase chain reaction-based methods was done for 47 RUT-positive biopsies and 13 H. pylori isolates. Results: Maximum resistance was seen to metronidazole (81.66%) followed by clarithromycin (45%) and quinolones (3.33%). No high-level resistance was seen to tetracycline. In clarithromycin-resistant cases, A2142G mutation was more prevalent than A2143G mutation. Multidrug resistance (resistance to metronidazole and clarithromycin) was seen in 41.66% of patients. Conclusions: Tetracycline and quinolones could be the antibiotics of choice in the eradication of H. pylori in this region, while recurrence of the infection with H. pylori could be expected among patients receiving either metronidazole or clarithromycin, for eradication therapy. DST should be done on a routine basis utilising both phenotypic and genotypic methods to prevent further emergence of resistance in this region.

RESUMO

BACKGROUND: In hepatitis C virus (HCV), infection viral and IL28B genotype along with many clinical and biochemical factors can influence response rates to pegylated interferon plus ribavirin (Peg-IFN-a/R) therapy and progression to chronic hepatitis C (CHC). AIMS: The present study was conducted to determine the effect of biochemical and risk factors on treatment outcome in CHC patients in relation to their viral and host genotype. SETTINGS AND DESIGN: The present study was a prospective Pe- IFN efficacy study consisting of Peg-IFN-a/R therapy for 24-48 weeks including 250 HCV infected patients. MATERIALS AND METHODS: Biochemical parameters were determined by Beckman Coulter AU680 automated analyzer. HCV and Interleukin 28B (IL28B) genotyping were carried out by polymerase chain reaction-restriction fragment length polymorphism and viral load was determined by quantitative real-time PCR. RESULTS: Wild outnumbered the variant genotypes in rs12979860, rs12980275, and rs8099917 SNP of IL28B gene. Sustained virological response (SVR) SVR and viral genotype were significantly associated with age, hepatic steatosis, low-grade varices, and serum aspartate transaminase levels (at the end of treatment) (P < 0.05). In addition, SVR was significantly influenced by body mass index (BMI), insulin resistance, serum low-density lipoprotein , and ferritin levels (P < 0.05). Viral genotype 1 infected patients had higher serum cholesterol and triglyceride levels (P < 0.05). CONCLUSIONS: Although the IL28B sequence variation is the major factor that can influence response rates to antiviral therapy, viral and biochemical factors also have a definite role to play in the diagnosis, etiology, and treatment outcome in HCV-infected patients.

RESUMO

INTRODUCTION: Viral genotype and variation in host genes involved in the immune response may predict the treatment response in patients infected with HCV. The present study was designed to determine the distribution pattern of HCV and host genotypes in Chronic Hepatitis C (CHC) patients and their association with virological response and other risk factors. METHODOLOGY: Two hundred and fifty (n = 250) HCV positive patients were included in the study. HCV and Interleukin 28B (IL28B) genotyping was carried out by PCR-RFLP. RESULTS: Viral genotype 3 was the predominant genotype seen in 187 (74.8%) patients. Wild genotype predominated in rs12979860, rs12980275 and rs8099917 SNP of IL28B gene. A significant difference was found in end stage virological response (EVR) between HCV genotype 1 infected patients with wild and variant genotype for rs12980275 and rs8099917 SNPs respectively (P < 0.05). On multivariate analysis all the SNPs were found to be associated with each other (P < 0.05) with rs12980275 SNP associated with history of Jaundice (P < 0.05). Viral genotype 3 was significantly associated with age (< 50 years) and rapid virological response (RVR) while as viral genotype 1 was significantly associated with history of surgery on multivariate analysis (P < 0.05). CONCLUSIONS: The viral genotype and IL28B polymorphisms are important factors to personalize antiviral therapy of patients with CHC.

RESUMO

BACKGROUND: Obesity among children and adolescents is a growing public health problem. The objective of this study was to evaluate the prevalence, risk factors and metabolic consequences of obesity among schoolchildren from Kashmir, India. METHODS: The study subjects (n=2024) included 870 boys and 1154 girls, aged between 6 and 18 years. Data were collected by interviewer-administered questionnaires. Information was obtained about different lifestyles, anthropometric parameters and dietary habits. Obesity was defined as body mass index (BMI) percentile as per the guidelines of Centers for Disease Control, 2000. For the evaluation of different clinical parameters, blood samples were collected from the subjects in the fasting state at 8 to 9 am after an overnight (10-12 h) fast. RESULTS: The highest representation of subjects was from fee-paying private schools. Out of the total subjects, 6.69% were overweight and 4.64% were obese. The hip circumference, abdominal circumference, BMI, blood pressure (BP), use of ready-made foods as well as the clinical parameters like glucose, phosphorous, cholesterol and triglycerides were found significantly higher among girls than boys (p<0.05). Boys were taller and were physically more active than girls (p<0.01). Compared to the boys (3.33%), the girls were found to be more obese (5.63%). Rural dwelling subjects (4.22%) exhibited a lower percentage of obesity than urban population (5.00%). The difference in obesity among the different age groups was found statistically significant (p<0.05). Additionally, children with active lives in the form of vigorous (10.59%) or moderate (10.34%) exercise decreased their chances of gaining weight substantially. CONCLUSIONS: Results from the present study have shown that prevalence of obesity among children was high in our population.

RESUMO

OBJECTIVE: Growth retardation is common in children with extrahepatic portal vein obstruction (EHPVO) and growth hormone (GH) resistance may play a dominant role. The aim of this study was to ascertain growth parameters and growth-related hormones in children with EHPVO, comparing with controls and to study the response of shunt surgery on growth parameters. MATERIALS AND METHODS: The auxological and growth-related hormone profile (GH; insulin-like growth factor binding protein-3 [IGFBP-3] and IGF-1) of thirty children with EHPVO were compared with controls. The effect of shunt surgery on growth parameters in 12 children was also studied. RESULTS: The mean height standard deviation score (HSDS) of cases (-1.797 ± 1.146) was significantly lower than that of controls (-0.036 ± 0.796); the mean weight SDS of cases (-1.258 ± 0.743) was also lower than that of controls (-0.004 ± 0.533). The mean GH level of cases (5.00 ± 6.46 ng/ml) was significantly higher than that of controls (1.78 ± 2.04 ng/ml). The mean IGF-1 level of cases (100.25 ± 35.93 ng/ml) was significantly lower as compared to controls (233.53 ± 115.06 ng/ml) as was the mean IGFBP-3 level (2976.53 ± 1212.82 ng/ml in cases and 5183.28 ± 1531.28 ng/ml in controls). In 12 patients who underwent shunt surgery, growth parameters significantly improved. CONCLUSIONS: Marked decrease in weight and height SDSs associated with GH resistance is seen in children with EHPVO, which improves with shunt surgery.

RESUMO

BACKGROUND: Hepatitis B virus (HBV) infection in cancer patients receiving chemotherapy carries high morbidity and mortality. Conventional hepatitis B vaccination with three doses at 0, 1, and 6 months apart is ineffective in prevention of HBV infection. OBJECTIVES: To compare the efficacy of accelerated, multiple, double-dose HB vaccine with conventional HB vaccine in cancer patients receiving chemotherapy (CT). METHODS: Patients of cancer who were planned for CT were screened for HBV markers (HBsAg, total anti-HB core, anti-HBs antibody and HBV DNA). Patients with negative HBV serum markers received HB vaccine in two groups. Group A received three double doses (40 µg) of recombinant HB vaccine at 0, 1, and 3 weeks before CT and additional three double doses post CT. Group B received HB vaccine (20 µg) at 0, 1, and 6 months. Efficacy of vaccine in the two groups was compared by anti-HBs titers achieved at 3, 6, and 9 months and by HBsAg positivity following CT at 1 year follow up. RESULTS: Protective anti-HBs titers (>10 mIU/mL) at 3, 6, and 9 months in group A and B was 41.1 %, 66.2 %, and 76% and 26 %, 37.7 %, and 49% respectively (p = 0.001). Seven of 454 (1.5%) patients in group A became HBsAg positive after vaccination compared to 19/472 (4.0%) in group B (p = 0.022). CONCLUSION: Accelerated, multiple, double-dose HB vaccine increases seroprotection and is more effective than conventional HB vaccine in preventing HBV infection.

RESUMO

BACKGROUND: Age, female sex, and obesity are considered to be risk factors for gallstone disease. The role of type 2 diabetes (T2D) in gallstone formation is still uncertain, and data in Indians is limited. OBJECTIVES: This is a case-control study to determine the prevalence of gallstones (GS) in patients with T2D, risk factors, and the relative risk compared with subjects without diabetes, selected from the general population. METHODS: Among 450 cases with T2D of a ≥2-year duration, 377 (88.8 %) participated. Diagnosis of GS was made at ultrasonography and history of cholecystectomy for GS. Controls were selected from the general population and diabetes excluded by oral glucose tolerance test. Cases and controls were matched for age, gender, and body mass index (BMI). RESULTS: Gallstones were seen in 67 (17.7 %) cases compared to 40 (5.8 %) in controls (p = 0.001). Prevalence increased with increasing age with peak in the sixth decade (23.4 % in cases and 4.4 % in controls (p = 0.001) and was higher in women (27.9 %) in cases and (7.8 %) in controls, (p = 0.001). In univariate analysis, risk factors for GS included age, female sex, BMI, multiparity, family history of GS, and high triglycerides and cholesterol with low high-density lipoprotein cholesterol. In multivariate analysis, age, (relative risk [RR] 1.54, confidence interval [CI] 1.1-2.1), female sex (RR 1.6, CI 1.0-1.9), and BMI (RR 1.5, CI 1.3-2.5) were the independent risk factors in gallstone formation. CONCLUSION: Patients with T2D had higher probability of having GS compared to the general population. Increasing age, female sex, and higher BMI were independently associated with gallstone disease.

RESUMO

BACKGROUND: Phospholipase C epsilon 1 (PLCE1) encodes a member of the phospholipase family of proteins that play crucial roles in carcinogenesis and progression of several cancers including esophageal cancer (EC). In two large scale genome-wide association studies (GWAS) single nucleotide polymorphisms (SNP, rs2274223A>G, rs3765524C>T) in PLCE1 were identified as novel susceptibility loci of esophageal cancer (EC) in China. The aim of the present study was to investigate this finding in Kashmir Valley, a high risk area. MATERIALS AND METHODS: We determined genotypes of three potentially functional SNPs (rs2274223A>G, rs3765524C>T and rs7922612C>T) of PLCE1 in 135 EC patients, and 195 age and gender matched controls in Kashmiri valley by PCR RFLP method. Risk for developing EC was estimated by binary logistic regression using SPSS. RESULTS: The selected PLCE1 polymorphisms did not show independent association with EC. However, the G2274223T3765524T7922612 haplotype was significantly associated with increased risk of EC (OR=2.92; 95% CI=1.30-6.54; p=0.009). Smoking and salted tea proved to be independent risk factors for EC. CONCLUSIONS: Genetic variations in PLCE1 modulate risk of EC in the high risk Kashmiri population.

RESUMO

Genetic alterations in the deleted in colorectal carcinoma (DCC) gene have been a priori reported to associate with metastasis in variety of human cancers. We investigated the association between potentially functional SNPs in DCC and susceptibility to esophageal (EC) and gastric (GC) cancers in Kashmir Valley. We genotyped two SNPs DCC rs714 (A>G) and DCC rs2229080 (C>G) of DCC in 135 EC patients, 108 GC patients, and 195 controls matched by age and sex in Kashmir Valley by polymerase chain reaction-RFLP method. Risk for developing EC and GC was estimated by binary logistic regression by using SPSS. We also performed a meta-analysis on DCC rs714 (A>G) and evaluated the association between the DCC rs714 (A>G) polymorphisms and cancer risk. A significant difference in DCC rs714 (A>G) genotype distribution between EC and GC cases and corresponding control groups was observed (odds ratio (OR) = 1.92; P = 0.03; P-trend = 0.04; false discovery rate (FDR) Pcorr = 0.03: OR = 2.15; P = 0.02; P-trend = 0.01; FDR Pcorr = 0.03). But no such association was observed in DCC rs2229080 (C>G). Further, DCC rs714 (A>G) AA genotype showed significantly increased risk for both gastric squamous cell carcinoma (OR = 5.63; P = 0.02; FDR Pcorr = 0.01) and gastric adenocarcinoma (OR = 2.15; P = 0.02; FDR Pcorr = 0.01). Smoking and salted tea are independently associated with both EC and GC, but gene-environment interaction did not further modulate the risk. Meta-analysis also suggested both independent and overall association of DCC rs714 (A>G) polymorphism with cancer (P = 0.000). In conclusion, genetic variations in DCC rs714 (A>G) modulate risk of EC and GC in high-risk Kashmir population.

RESUMO

BACKGROUND: Increasing resistance against Helicobacter pylori has resulted in reduced eradication rates. OBJECTIVE: This study aims to determine whether eradication rates for H. pylori infection with sequential therapy is better than standard triple therapy. PATIENTS: Patients with endoscopy documented peptic ulcer and H. pylori infection confirmed by histology and rapid urease test. INTERVENTION: Patients were randomized into two groups; 134 received standard triple therapy (pantoprazole 40 mg, clarithromycin 500 mg and amoxicillin 1 g each administered twice daily) for 10 days and 138 received sequential regimen (pantoprazole 40 mg plus amoxicillin 1 g twice daily for 5 days followed by 40 mg pantoprazole, 500 mg clarithromycin, and 500 mg tinidazole each administered twice daily for 5 days). Eradication was confirmed by histology and rapid urease test. Compliance and adverse effects were determined by the recovery of empty medicine strips and questioning. RESULTS: The eradication rates with sequential therapy were significantly greater than with standard therapy on both intention-to-treat analysis (76.0 % vs. 61.9 %, p = 0.005; difference, 14.1 % [95 % CI, 6.5-19 %] and per protocol analysis (84.6 % vs. 67.4 %, p = 0.002; difference, 17.2 % [95 % CI, 8.5-23.5 %]). The incidence of side effects did not differ between the two therapy groups. One patient in standard therapy discontinued treatment due to side effects. LIMITATION: Cultures were not performed. Loss to follow up was 5.2 % in standard therapy and 6.5 % in sequential therapy. CONCLUSION: Sequential therapy was significantly more effective than standard therapy for eradicating H. pylori infection in peptic ulcer disease in Asian patients. Side effects were similar.

RESUMO

Although splenic involvement alone in hydatid disease is very rare, spleen is the third most common organ involved in hydatid disease. The rarity of splenic hydatid disease poses a diagnostic challenge for clinicians, particularly in non-endemic areas. As the hydatid cyst can present as a simple cyst without having the classic serological and imaging features, and later can lead to life-threatening complications like anaphylaxis, hydatid disease of spleen should be considered in differential in every patient in endemic areas with cystic lesion of spleen until proved otherwise. The author used the keyword "splenic hydatid cyst" in PubMed and reviewed the scientific literatures published from January 1965 to June 2012. The present review is to accentuate the incidence, classification, clinical and pathophysiological features, differential diagnosis, diagnostic modalities, and treatment choices of hydatid cyst of spleen along with follow-up strategy and newer treatment approaches.

RESUMO

BACKGROUND AND AIM: Epidemiology of Helicobacter pylori infection has regional variation. Effect of eradication of H. pylori on symptoms of functional dyspepsia is uncertain, and the data in Asian scenario are scanty. The study aimed to see H. pylori positivity rate in patients of functional dyspepsia and the effect of its eradication on symptoms. METHODS: Randomized, double-blind, placebo-controlled study was the study design used. Patients of functional dyspepsia defined as per Rome 2 criteria were tested for H. pylori infection by rapid urease test and gastric biopsy. H. pylori-positive patients were randomly allocated to triple therapy (20 mg of omeprazole, 500 mg of clarithromycin, and 1000 mg of amoxicillin orally two times daily) and omeperazole plus identical placebo for 2 weeks. Symptoms were assessed with the weekly Likert scale. RESULTS: H. pylori positivity rate in functional dyspepsia was 1160/2000 (58%). At 6 weeks, the eradication rate for H. pylori in triple therapy and placebo group was (181/259 [69.8%] and 13/260 [5.0%], P = 0.001), respectively. On intention-to-treat analysis, the symptom resolution at 1 month was (157/259 [60.7%] and 136/260 [52.3%], P = 0.38), respectively. At 12 months, H. pylori eradication and healing of gastritis in triple therapy and placebo group were (116/174 [66.7%] and 12/180 [6.7%], P = 0.001) and (132/174 [75.9%] and 11/180 [6.1%], P = 0.001), respectively. On intension to treat, the resolution of symptoms in triple therapy and placebo group was (95/217 [43.7%] and 72/195 [36.9%], P = 0.13). CONCLUSION: There is high H. pylori positivity rate in patients of functional dyspepsia. The eradication of H. pylori does not resolve the symptoms despite healing of gastritis.

RESUMO

BACKGROUND AND OBJECTIVES: There is no ideal therapy for eradication of Helicobacter pylori infection. We evaluated the efficacy and safety of 1-week triple therapy with rabeprazole, levofloxacin, and tinidazole in a metronidazole resistance prevalent region for eradicating H. pylori infection in patients with gastroduodenal ulcers. METHODS: This was an open-label, prospective study. Consecutive patients with endoscopy-proven duodenal or gastric ulcer and who were H. pylori-positive were treated with levofloxacin 500 mg once a day, rabeprazole 20 mg twice a day, and tinidazole 500 mg twice daily for 7 days followed by rabeprazole 20 mg OD for 8 weeks. Endoscopy was repeated 8 weeks after the end of therapy to check for ulcer healing and H. pylori status. RESULTS: One hundred and thirty-one patients with gastroduodenal ulcers (duodenal 118, and gastric 13) were included. Drug compliance was 97.7 %. The eradication rate of H. pylori by intention-to-treat analysis was 85.5 % (95 % confidence interval 79.5-91.5) (112 of 131 patients) and by per-protocol analysis was 91.8 % (95 % confidence interval 86.9-96.7) (112 of 122 patients). Adverse effects were reported in 17 %: abdominal pain in 3.05 %, metallic taste in 6.87 %, and nausea and vomiting in 4.58 %. CONCLUSIONS: Levofloxacin-tinidazole-based triple therapy was highly effective and safe as a first-line regimen in Indian patients with gastroduodenal ulcer disease associated with H. pylori infection. The regimen was well tolerated.

RESUMO

BACKGROUND: Hepatolithiasis affecting the left hepatobiliary system is common in the Asia Pacific region. This aim of this study was to describe an experience with the diagnosis and treatment of patients with isolated left-sided hepatolithiasis. METHODS: One hundred and ten patients with isolated left-sided hepatolithiasis who underwent a left-sided hepatic resection between January 1999 and February 2010 were included for further analysis. The clinical profile, cholangiograms, operative procedures and early and late results were examined. RESULTS: Analysis of magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) findings revealed left hepatic ductal anatomical details in 101 patients. Three types of left hepatic ductal variations were observed (type 1 in 90.1%, type 2 in 5.9% and type 3 in 4.0% patients). Eighty-four (76.4%) patients had the presence of strictures in the left hepatic ductal system and in 26 (23.6%) patients no strictures could be seen. Out of 84 patients with strictures, 78 could be classified (type I in 89.7% and type II in 10.3%). Of the 110 patients, 75 (68.2%) underwent a left lateral sectionectomy, 33 (30%) a left hepatectomy and 2 (1.8%) patients were treated with a left hepatectomy combined with a caudate lobe resection. Of the patients who underwent a left hepatectomy 11.4% developed a bile leak. Eight per cent of patients who underwent a left lateral sectionectomy had infective complications. During a median follow-up period of 63 (range 3-134) months, 2 (2.1%) patients were discovered to have residual stones and five (5.2%) others possessed recurrent stones. CONCLUSIONS: This study highlights the impact of the presence or absence of bile duct stricture on the clinical and histological profile of patients as well as their operative and the post-operative behaviour. It is concluded that hepatic resection is an appropriate treatment modality in localized left-sided hepatolithiasis.

RESUMO

Esophageal cancer (EC) is a complex multifactorial disorder, where environmental and genetic factors play major role. NADPH:quinone oxidoreductase 1 (NQO1) and NRH:quinone oxidoreductase 2 (NQO2) are phase II cytosolic enzymes that catalyze metabolism of quinones, important in the detoxification of environmental carcinogens. A case-control study was performed to investigated the associations of NQO1 609C>T and NQO2 -3423G>A polymorphisms with susceptibility to EC in a high-risk Kashmiri population of India in 135 EC patients and 195 unrelated healthy controls using PCR-RFLP. We also performed a meta analysis of nine published studies (1,224 cases and 1,740 controls) on NQO1 609C>T and evaluated the association between the NQO1 609C>T polymorphisms and esophageal cancer risk. A significant difference in NQO1 609C>T and NQO2 -3423G>A genotype distribution between EC cases and corresponding controls groups was observed (OR = 2.65; 95 % CI = 1.29-5.42 and OR = 1.88; 95 % CI = 1.02-3.49 respectively). Further, gene-gene interaction showed significantly increased risk for esophageal adenocarcinoma with variant genotypes of NQO1 609C>T and NQO2 -3423G>A polymorphisms and interaction with environmental risk factors revealed pronounced risk of EC with NQO1 609C>T TT genotype in high salted tea users of Kashmir valley (OR = 3.72, 95 % CI = 0.98-14.19). Meta analysis of NQO 609C>T polymorphism also suggested association of the polymorphism with EC in Asians as well as Europeans. In conclusion, NQO1 609C>T and NQO2 -3423G>A genetic variations modulate risk of EC in high-risk Kashmir population.

RESUMO

BACKGROUND AND AIM: Small bowel follow through (SBFT) and enteroclysis have low sensitivity in picking up lesions in obscure gastrointestinal bleed (OGIB). Computed tomographic enterography (CT-EG), performed with 64-slice multiphase CT system by using large volumes of ingested neutral enteric contrast material, has high spatial and temporal resolution in visualization of the small bowel wall and lumen. The role of 64-slice multiphase CT-EG in the evaluation of OGIB is still evolving, and data on this role are scarce. We evaluated the efficacy of 64-slice multiphase CT-EG using polyethylene glycol (PEG) electrolyte solution as neutral contrast in patients of OGIB. METHODS: CT-EG was performed with 64-slice multiphase CT system using large volume (2,000 mL) of PEG electrolyte solution as oral contrast in patients of OGIB. RESULTS: Thirty-five patients (21 men, age 41.4 [13.5] y, range 19-70 year) with OGIB underwent CT-EG; 20 patients had overt OGIB whereas 15 patients had occult OGIB. Among 15 patients with occult OGIB, 10 patients had iron deficiency anemia (IDA) with fecal occult blood test (FOBT) positive and 5 had IDA with FOBT negative. Thirty-two patients (92 %) completed the procedure successfully. The total time taken for the ingestion of 2,000 mL of PEG electrolyte solution was median 64 (range 60-78) minutes. Adequate luminal distension of small bowel was seen in 29 (90.6 %) patients for successful interpretation of radiological images. Fifteen of 32 (46.9 %) patients had positive findings on CT-EG; 12 of them underwent exploratory laparotomy. The surgical findings were in conformity with CT-EG findings in all patients, which included gastrointestinal stromal tumors (GIST; n = 6), carcinoid (1), Meckel's diverticulum (1), small bowel adenocarcinoma (2) and jejunal vascular malformation (2). CONCLUSION: 64-slice multiphase CT-EG is a useful investigation in the evaluation of both occult and overt OGIB.
