RESUMO
BACKGROUND: Intestinal amebiasis is endemic in India, with myriad clinical presentations. The liver is the most common extra-intestinal organ to be involved in invasive amoebiasis up to 37% of cases. Synchronous presentation of hepatic and intestinal disease is unusual, and presentation as acute gastrointestinal bleed, or amoeboma even more atypical. GOALS: We aimed to assess the frequency of synchronous hepatic and colonic amebiasis and the efficacy of endoscopic management of colonic bleeding. RESULTS: We screened 52 consecutive patients with amebic liver abscess for synchronous intestinal amoebiasis and report the clinical course of 28 patients (mean age 48.3 years, all male) with amoebic liver abscess (ALA), (mean size, 7.2 ± 2.8 cm) who presented to us with lower gastrointestinal bleed requiring endotherapy. Patients with synchronous infection had higher bilirubin, liver enzymes and prothrombin time. Most needed percutaneous drainage of the liver abscess, and had prolonged hospital stay. They had ileocaecal ulcers with active bleeding; ulcer with adherent clot in 10(50%), and visible vessel in 8(37.5%), or active ooze in 4(12.5%). One patient had an ulcerated rectal mass, which appeared malignant on endoscopy, which was later found to be an amoeboma on microscopy. Hemostasis was achieved with dilute epinephrine injection, one patient required argon plasma coagulation, and 4 subjects required haemoclip placement at the site to control ooze from a visible vessel. CONCLUSION: Synchronous hepatic and intestinal amoebiasis is not uncommon, and often requires endoscopic haemostasis in case of gastrointestinal bleeding due to colonic disease. We report the successful endoscopic control of bleeding amoebic ulcers in all 24 patients.

OBJECTIVE: To study if chronic pancreatitis (CP) is a risk factor for pancreatic cancer. METHODS: Through a cohort and a case-control study design, CP and other important risk factors including smoking, diabetes, alcohol, obesity, and genetic mutations were studied for their association with pancreatic cancer. RESULTS: In the cohort study, 402 patients with CP were included. During 3967.74 person-years of exposure, 5 of the 402 patients (4 idiopathic CP, 1 hereditary CP) developed pancreatic cancer after 16.60 ± 3.51 years of CP. The standardized incidence ratio was 121. In the case-control study, 249 pancreatic cancer patients and 1000 healthy controls were included. Of the 249 patients with pancreatic cancer, 24 had underlying idiopathic CP, and none had alcoholic pancreatitis. SPINK1 gene mutation was present in 16 of 26 patients with idiopathic CP who had pancreatic cancer. Multivariable analysis showed CP (odds ratio [OR], 97.67; 95% confidence interval [CI], 12.69-751.36), diabetes (>4 years duration) (OR, 3.05; 95% CI, 1.79-5.18), smoking (OR, 1.93; 95% CI, 1.38-2.69) as significant risk factors for pancreatic cancer. The population attributable risk was 9.41, 9.06, and 9.50 for diabetes, CP, and smoking, respectively. CONCLUSIONS: Genetically determined CP but not alcoholic CP is a strong risk factor for pancreatic cancer.

BACKGROUND: Chronic hepatitis B is a disease of concern due to its life-threatening complications like cirrhosis, and hepatocellular carcinoma (HCC) in 20-40% of patients. There are about 400 million people affected worldwide with HBV, and over 300,000 die every year from HBV-related diseases. Oral antivirals like lamivudine, adefovir, entecavir, and tenofovir are commonly used to treat chronic hepatitis B. In this study, we tried to evaluate the comparative efficacy of these drugs alone and in combination. MATERIALS AND METHODS: Chronic hepatitis B patients with HBV-DNA more than 104Copies/mL irrespective of their HBeAg status (n=60) were enrolled in a prospective study. 21, 20, and 19 patients were treated with lamivudine (100 mg/day) plus adefovir (10 mg/day) combination entecavir monotherapy (0.5 mg/day) and tenofovir monotherapy (300 mg/day), respectively and were followed up for 24 weeks with their virological, serological, and biochemical markers measured at 12 and 24 weeks. RESULTS: After 24 weeks of treatment, there was no significant difference between the 3 groups in suppressing HBV-DNA to undetectable levels. The median decrease in HBV-DNA levels from baseline was better with tenofovir and entecavir monotherapies than lamivudine and adefovir combination, which was statistically significant. There was no significant difference between the 3 groups in HBsAg and HBeAg seroconversion and normalization of biochemical parameters. CONCLUSION: Entecavir and tenofovir monotherapy were found to be more effective than lamivudine plus adefovir combination in reducing the HBV-DNA levels. However, lamivudine plus adefovir combination was not too inferior, especially when cost of treatment was taken into consideration.
RESUMO
BACKGROUND: Increased intestinal permeability (IP) has been implicated in the etiopathogenesis, disease activity and relapse of Crohn's disease (CD). Glutamine, the major fuel for the enterocytes, may improve IP. AIM: We evaluated the effect of oral glutamine on IP and intestinal morphology in patients with CD. METHODS: In a randomized controlled trial, consecutive patients with CD in remission phase with an abnormal IP were randomized to a glutamine group (GG) or active control group (ACG) and were given oral glutamine or whey protein, respectively, as 0.5 g/kg ideal body weight/day for 2 months. IP was assessed by the lactulose mannitol excretion ratio (LMR) in urine, and morphometry was performed by computerized image analysis system. RESULTS: Patients (age 34.5 ± 10.5 years; 20 males) were assigned to the GG (n = 15) or ACG (n = 15). Fourteen patients in each group completed the trial. The LMR [median (range)] in GG and ACG at 2 months was 0.029 (0.006-0.090) and 0.033 (0.009-0.077), respectively, with P = 0.6133. IP normalized in 8 (57.1%) patients in each group (P = 1.000). The villous crypt ratio (VCR) [mean (SD)] in GG and ACG at 2 months was 2.68 (1.02) and 2.49 (0.67), respectively, (P = 0.347). At the end of 2 months LMR improved significantly in GG from 0.071 (0.041-0.254) to 0.029 (0.006-0.090) (P = 0.0012) and in ACG from 0.067 (0.040-0.136) to 0.033 (0.009-0.077) (P = 0.0063). VCR improved in the GG from 2.33 (0.77) to 2.68 (1.02) (P = 0.001), and in ACG from 2.26 (0.57) to 2.49 (0.67) (P = 0.009). CONCLUSIONS: Intestinal permeability and morphology improved significantly in both glutamine and ACG.

BACKGROUND: The alterations in the body composition (BC) in both the active and remission phase of Crohn's disease (CD) are poorly characterized. OBJECTIVE: To assess the BC of the patients with CD in active and remission phase, and compare with healthy controls (HC). METHODS: BC was assessed by bioelectrical impedance analysis using Tanita TBF-215 leg to leg portable impedance analyzer in 123 patients with CD and 100 matched HC. Diet intake was assessed by 24 hours diet recall method. RESULTS: The mean age of patients was 36.4 +/- 12.6 years and 56% were males. Patients in active phase as well as in remission phase had a lower BMI than HC (18.8 +/- 3.6 vs. 23.9 +/- 4.0; p = 0.001 and 18.8 +/- 3.6 vs. 21.6 +/- 5.0; p = 0.002). The fat mass (FM) in active phase was significantly lower than that in remission phase (8.2 +/- 5.9 vs. 13.4 +/- 10.6 kg; p = 0.005) and HC (8.2 +/- 5.9 kg vs. 14.1 +/- 7.5 kg; p = 0.001). FM did not differ between remission phase and HC. The fat free mass (FFM) of HC was significantly higher than that of both remission phase (48.9 +/- 7.4 kg vs. 43.3 +/- 10.4 kg; p = 0.001) and active phase (48.9 +/- 7.4 kg vs. 40.7 +/- 8.5 kg; p = 0.001). There was no difference in the FFM of patients in both phases; p = 0.356. The intake of macronutrients was comparable between the two phases; however lower than that of HC. CONCLUSION: Both FM and FFM were depleted in the active phase, while only FFM was deficient in the remission phase of CD, indicating a poor recovery of lean mass in remission.

BACKGROUND AND AIM: Patients with chronic pancreatitis are often malnourished. The role of malnutrition in the pathogenesis of chronic pancreatitis is unclear. The aim of the present article was to study prospectively the cause and effect relationship of malnutrition with idiopathic chronic pancreatitis in a case-control study. METHODS: Consecutive patients with chronic pancreatitis underwent anthropometry, nutritional and dietary assessments. For dietary assessment, food frequency questionnaire and 24-hour dietary recall methods were used. Primary outcome measure was cause and effect relationship of malnutrition with idiopathic chronic pancreatitis. RESULTS: Of 201 patients with chronic pancreatitis, 120 had idiopathic chronic pancreatitis (mean age 29.60 years, 74 males) who formed the study group. None of the patients consumed cassava. The nutritional status and dietary intake of the patients before the onset of chronic pancreatitis were comparable with those of controls with 20.6% of patients and 22.5% of controls being malnourished (body mass index [BMI] < 18.5). After the onset of chronic pancreatitis, 56.5% of patients lost weight and significantly more patients became malnourished compared with controls (45.8% vs 22.5%; P < 0.001). The causes of weight loss were diabetes, higher calories from proteins, and pseudocyst. CONCLUSION: Malnutrition was not a cause of idiopathic chronic pancreatitis and weight loss occurred as an effect of chronic pancreatitis. Cassava was not found to be a cause of idiopathic chronic pancreatitis.

PURPOSE: Enteral nutrition (EN) is effective, easy to provide, cheaper, and associated with fewer complications in comparison with parenteral nutrition in severe acute pancreatitis (SAP). However, the nasogastric (NG) route for enteral supplements still remains to be established, and most studies have used the nasojejunal (NJ) route. The purpose of this study was to compare early NJ with NG feeding in SAP. PATIENTS AND METHODS: A total of 31 patients with SAP were randomized to feeding by either NG (15 patients) or NJ (16 patients). A semi-elemental formula was used through an enteral tube in both groups. Nutritional parameters (anthropometry, serum prealbumin and albumin levels) were recorded at baseline and after 7 days. Recurrence of pain and tolerance of feeding was noted. RESULTS: Recurrence of pain occurred in only 1 patient each in the 2 groups. Diarrhea occurred in 3 and 4 patients in the NJ and NG groups, respectively. There were 4 deaths in the NJ group and 5 in the NG group. Two patients in the NJ group and 1 in the NG group underwent surgery. There was no difference in the outcome measures (ie, discharge, surgery, and death). There was a decline in nutritional parameters in both groups. CONCLUSIONS: EN at a slow infusion is well tolerated by both NJ and NG routes in patients with SAP. Neither NJ nor NG feeding leads to recurrence or worsening of pain in SAP. Nutritional parameters remained unaffected because of inadequate calorie intake during the first week of feeding.
