Early enteral nutrition in severe acute pancreatitis: a prospective randomized controlled trial comparing nasojejunal and nasogastric routes.

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.

An epidemic of veno-occlusive disease of liver in central India.

An outbreak of veno-occlusive disease which was probably caused by consumption of cereals mixed with seeds of a plant (Crotalaria sp.) containing pyrrolizidine alkaloids occurred in the Sarguja district of India in November-December 1975. 42% of the 67 recorded cases died.

Mother-to-child transmission of hepatitis E virus infection

Objectives : Water borne or enterically transmitted non-A-non-B hepatitis is a major public health problem in India. Many of these cases carry fatal outcome. The hepatitis E virus (HEV) has been considered to be the most important causative agent of this entity. The severity and fatality rates of HEV infection are reported to be rather more in pregnant women. However, there is meager information from India, on mother to child transmission of this agent.Methods : During 1997-98, we studied 60 pregnant women suspected to have acute viral hepatitis to understand the frequency of various viral etiologies, disease course and outcome of the pregnancy. Six cord blood samples were tested for IgG, and IgM antibodies against hepatropic viral agents and also for hepatitis E virus RNA by RT-nested PCR using ORF-1 as target.Results : Of the 60 pregnant patients hospitalised at All India Institute of Medical Sciences, New Delhi for acute hepatitis, 22 (37%) were positive for IgM anti-HEV antibodies and 10% were infected with hepatitis B virus. Co-infection of HEV with Hepatitis B and C was seen in 1 and 2 patients, respectively. Most (72%) of the HEV infected patients were in third trimester of pregnancy (P<0.05). Of the 6 cord blood samples tested 3 (50%) were positive for HEV RNA. Though, all mothers were RNA positive, half of the babies did not get infectedin utero with HEV. Fourteen of the 22 (63.6%) HEV infected mothers developed fulminant hepatic failure and all died.Conclusion : The mortality rate in HIV infected mothers was 100%. Mother to child transmission of hepatitis E virus infection was established in 50%

Evaluation of early enteral feeding through nasogastric and nasojejunal tube in severe acute pancreatitis: a noninferiority randomized controlled trial.

Objective This study aimed to determine the noninferiority of early enteral feeding through nasogastric (NG) compared to nasojejunal (NJ) route on infectious complications in patients with severe acute pancreatitis (SAP). Methods Patients with SAP were fed via NG (candidate) or NJ (comparative) route. The primary outcome was the occurrence of any infectious complication in blood, pancreatic tissue, bile, or tracheal aspirate. Secondary end points were pain in refeeding, duration of hospital stay, intestinal permeability assessed by lactulose/mannitol excretion, and endotoxemia assessed by endotoxin core antibody types immunoglobulin G and M. Results Seventy-eight patients were randomized to feeding by either the NG or the NJ route. During the hospital stay, the presence of any infectious complication in the NG and NJ groups was 23.1% and 35.9% (significantly different), respectively. The effect size of the difference of infectious complications was −12.8 (95% confidence interval, −29.6 to 4.0). The upper limit of the 95% confidence interval was 4.0 and was within the 5% limit set for noninferiority. The value of 8.0 for the number needed to treat implies that 8 patients should be treated with NG compared with the NJ group to prevent 1 patient from any of the infectious complications. Conclusions Early enteral feeding through NG was not inferior to NJ in patients with SAP. Infectious complications were within the noninferiority limit. Pain in refeeding, intestinal permeability, and endotoxemia were comparable in both groups.

Auditory P300 event-related potentials and number connection test for evaluation of subclinical hepatic encephalopathy in patients with cirrhosis of the liver: A follow-up study

Background and Aims: The P300 event‐related potentials (P3ERP) have been recently advocated for detection of cognitive disturbances in early encephalopathy. However, no systematic follow‐up study has been conducted to understand the clinical significance of subclinical hepatic encephalopathy (SHE) detected by this or other methods. The present study was therefore undertaken to examine the diagnostic usefulness of auditory P3ERP in the detection of SHE, to compare it with that of the number connection test (NCT), and to investigate the clinical outcome of patients with SHE in terms of progression to overt encephalopathy.

Acute liver failure. Experience with 145 patients.

Acute liver failure (ALF) is an uncommon but serious disease still carrying a high mortality. This report describes one of the largest series of cases of acute failure, managed on a simple intensive supportive therapeutic regimen. One hundred fifty-eight patients with ALF were admitted to the Rajgarhia Liver Unit of the All-India Institute of Medical Sciences (AIIMS) during the period July 1976 to December 1981. Data from 145 were completed and analyzed for this report. Of the patients, 85.4% were below the age of 40 years. The female-to-male ratio was 1.3:1. Of the 77 women in the reproductive age group, 59.7% were pregnant. All cases of ALF were secondary to viral hepatitis. Cerebral edema, bleeding, infection, and renal failure were seen in 57.2, 57.2, 39.3, and 16.5% of patients, respectively. Overall survival was 28.9% of patients. It was 33% below the age of 40 years and only 4.8% above this age. Pregnancy did not adversely affect the prognosis. Survival was related to grade of coma, being 22.8% for patients in Grade IV coma and 62% for patients in Grade I coma. In fatal cases the immediate complications resulting in death were cerebral edema (63%), bleeding (30%), renal failure (10.6%), and infection (8.7%). Presence of HBsAg, a serum bilirubin of over 20 mg%, and serum sodium less that 119 mEq/liter were indicators of poor prognosis. A simple, intensive, support therapy yielded results comparable to those reported by centers using a variety of complex therapeutic regimens.

Dietary Counseling Versus Dietary Supplements for Malnutrition in Chronic Pancreatitis: A Randomized Controlled Trial

BACKGROUND & AIMS Up to 50% of patients with chronic pancreatitis (CP) are malnourished. There are limited data on the role of dietary intervention in improving the nutritional status of such patients. The aim was to compare the efficacy of medium chain triglyceride (MCT)-enriched commercial dietary supplements with dietary counseling for homemade food in the management of malnutrition in patients with CP. METHODS In a randomized controlled trial, consecutive undernourished patients with CP (body mass index [BMI] <18.5 kg/m(2)) at a tertiary care hospital were randomized to receive either dietary counseling for regular homemade food or commercial MCT-enriched dietary supplements for a period of 3 months to compensate for the dietary calorie deficit. All patients received standard management for CP including pancreatic enzyme supplements. Primary outcome measure was improvement in BMI. RESULTS Sixty malnourished patients with CP were randomized to counseling group (n = 29; mean age, 32 +/- 10 years; male, 83%) and supplementation group (n = 31; mean age, 28 +/- 10 years; male, 84%). BMI increased in both the counseling group and supplementation group (17.2 +/- 1.7 vs 18.1 +/- 1.8 kg/m(2), P = .001; 16.7 +/- 1.6 vs 18.2 +/- 1.6 kg/m(2), P = .001). There were similar improvements in triceps skinfold thickness, dietary intake, fecal fat, and pain score during a period of 3 months in both groups. There was, however, no significant difference between the counseling and supplementation groups with regard to any of the outcome measures. CONCLUSIONS Dietary counseling for a balanced homemade diet is as good as commercial food supplements in improving malnutrition in patients with CP.

Role of horizontal transmission in hepatitis B virus spread among household contacts in north India.

Objectives: Familial clustering of HBV provides epidemiological evidence for the different modes of spread of the virus. Though the majority of the studies have addressed the issue of perinatal transmission in India, only a few reports have dealt with other modes of transmission. Methods: The study was prospectively designed and data were collected from a total of 265 household contacts of 91 index patients with HBV-related chronic liver disease between January 2006 and July 2007. The prevalences of HBsAg and various antibodies; anti-HBs, anti-HBc and anti-HBe, were estimated in all household contacts using ELISA and VIDAS. Results: Among the various household contacts, the highest prevalence of HBsAg was seen in the pediatric age group (kids 1–15 years: 37.0%) and especially in siblings (48.3%), with statistical significance (p < 0.001). Hepatitis B virus (HBV) serological markers were found more commonly in contacts of female (68.8%) index patients as compared to males (p > 0.05). The development of anti-HBV antibodies showed an increasing trend with age (p < 0.001), with the highest prevalence in parents. Conclusion: Horizontal transmission plays an important role in contributing to the high prevalence of HBsAg especially in young children. Hence, this age group needs to be targeted for primary prevention and effective vaccine.
