Seroepidemiology of hepatitis A virus infection among school children in Delhi and north Indian patients with chronic liver disease: implications for HAV vaccination.

BACKGROUND: Universal vaccination against hepatitis A virus (HAV) has been recommended for children because of the changing epidemiological pattern of HAV. Vaccination has also been advised for patients with chronic liver disease as HAV superinfection in these patients can result in severe or even fatal disease. In India, the indications for HAV vaccination are not clear due to contradictory seroepidemiological data in children and lack of data on HAV seroprevalence in patients with chronic liver disease. METHODS: Sera were collected from children studying in two government-run schools and from patients with chronic liver disease attending the Liver Clinic at the All India Institute of Medical Sciences (AIIMS). The sera were tested for anti-HAV antibodies. The incidence of HAV-induced acute hepatitis and acute liver failure at AIIMS over the last 10 years was also assessed. RESULTS: A total of 93.2% (1328/1424) of the school children between 4-18 years of age who were included in the study had anti-HAV antibody in their sera. Eighty percent of the children had antibodies against HAV in their sera by the age of 5 years, whereas all the children above 16 years were positive for anti-HAV antibody. A total of 256 patients with chronic liver disease (94 with cirrhosis of the liver, 160 with chronic hepatitis) were tested for the presence of anti-HAV antibody. Of them, 97.6% (248/254) had anti-HAV antibody in their sera. The annual frequency of HAV-induced acute viral hepatitis and acute liver failure at AIIMS during the last 10 years did not show any change. CONCLUSION: Mass vaccination against HAV is not required in north India because of the presence of protective antibodies against HAV in the majority of the population.

Vaccination against hepatitis A virus may not be required for schoolchildren in northern India: results of a seroepidemiological survey.

OBJECTIVES: To evaluate the current seroprevalence of antibodies against hepatitis A virus (HAV) in a sample of schoolchildren above 10 years of age and to determine the prevalence of HAV-induced hepatitis in adults at a tertiary care hospital in northern India between January 1992 and December 2000. METHODS: Sera from 276 male and 224 female schoolchildren aged 10-17 years were tested for anti-HAV antibodies by enzyme-linked immunosorbent assay. Consecutive patients with a diagnosis of acute viral hepatitis who attended a liver clinic were tested for the serological markers of HAV, hepatitis B Virus, hepatitis C virus, hepatitis D virus, and hepatitis E virus. FINDINGS: Of the male and female children, 96.3% and 98.2%, respectively had anti-HAV antibodies in their sera. The prevalence of these antibodies in the age groups 10-12, 13- 14, and 15-17 years were 98.6%, 94.8%, and 98.3% respectively. The frequency of HAV- induced acute viral hepatitis (69/870, 8%) in adults did not show an increasing trend. CONCLUSION: Mass HAV vaccination may be unnecessary in northern India because the seroprevalence of protective antibodies against HAV in schoolchildren aged over 10 years remains above 95% and there has been no apparent increase in HAV-induced acute viral hepatitis in adults.

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.

Oxidant stress and antioxidant status among patients with nonalcoholic fatty liver disease (NAFLD).

BACKGROUND: One of the major pathogenic mechanisms for progression of nonalcoholic fatty liver disease (NAFLD) is oxidative stress. Recently, many studies have demonstrated the role of oxidative stress in NAFLD however, studies describing the antioxidant status in these patients are lacking. AIM: To study the levels of oxidative stress and antioxidant status among patients with NAFLD. PATIENTS AND METHODS: It was a prospective study in which 29 patients with NAFLD, 25 diseased controls with chronic viral hepatitis, and 23 healthy controls were enrolled. Apart from standard biochemical parameters, lipid peroxidation products were measured as thiobarbituric acid reactive substances. As measures of antioxidant capacity, superoxide dismutase, vitamin C levels and ferric reducing ability of plasma were measured. RESULTS: Level of thiobarbituric acid reactive substances was significantly higher among NAFLD patients as compared with diseased [4.7 nmol/mL (1.0 to 10.2) vs. 2.4 nmol/mL (0.8 to 10.7); P=0.02] or healthy controls [4.7 nmol/mL (1.0 to 10.2) vs. 1.8 nmol/mL (0.5 to 4.1); P=0.0001]. FRAP was found to be significantly higher in patients with NAFLD as compared with healthy controls [450.3 (197.6 to 733.3) vs. 340.8 (141.6 to 697.5) mumol Fe liberated; P=0.04], even though it was similar between NAFLD and diseased controls. Among NAFLD patients, there was no significant correlation between histological grading or staging and levels of pro and antioxidants. CONCLUSIONS: Products of lipid peroxidation are significantly increased among patients with NAFLD as compared with chronic viral hepatitis or healthy controls. Larger studies and newer markers of oxidative stress are required to clarify the association between oxidative stress and histological severity in NAFLD.

Vaccination for hepatitis A virus is not required for patients with chronic liver disease in India.

BACKGROUND: Hepatitis A virus (HAV) vaccination is recommended worldwide for patients with chronic liver disease to prevent decompensation due to superinfection with HAV. India being endemic for HAV, the prevalence of pre-existing antibodies against HAV due to subclinical exposure to the virus in childhood among patients with chronic liver disease may be high and, therefore, vaccination may not be needed. However, data are lacking on the prevalence of HAV antibody among patients with chronic liver disease in India. METHODS: Two hundred fifty-four patients attending the Liver Clinic at the All India Institute of Medical Sciences, New Delhi during the past 5 years and diagnosed to have either chronic hepatitis due to the hepatitis B virus (n = 76), hepatitis C virus (n = 84) or cirrhosis of the liver due to the hepatitis B (n = 47) or C (n = 47) virus were tested for the presence of IgG anti-HAV antibody in their sera (using a commercial ELISA kit). RESULTS: Two hundred forty-eight (97.6%) patients tested positive for IgG anti-HAV. The prevalence of anti-HAV positivity was similar among patients with chronic hepatitis B (74, 97.4%), chronic hepatitis C (82, 97.6%), cirrhosis of the liver due to the hepatitis B (46, 97.8%) and hepatitis C (46, 97.8%) virus. CONCLUSION: Vaccination against HAV is not required among patients with chronic liver disease in India as there is a very high prevalence of pre-existing antibodies in these patients.

Micronutrient antioxidant intake in patients with chronic pancreatitis.

Increased oxidative stress has been postulated to be an important mechanism in the pathophysiology of chronic pancreatitis (CP). Micronutrient deficiency may increase the oxidative stress as they assist in free radical clearance. The present study was undertaken to assess the intake of micronutrients, i.e. vitamins E and C, carotene, selenium, copper, zinc, manganese, magnesium, sulphur, riboflavin, methionine and choline in patients with CP. All consecutive patients with CP attending the Pancreas Clinic at the All India Institute of Medical Sciences were enrolled in the study. The usual dietary intake was estimated by the 24-hour dietary recall method and food frequency questionnaire. Dietary restrictions, if any, were also noted. The micronutrient intake of patients not on any nutritional supplements (n=75, 65 males and 10 females, mean age 31.06 +/- 10.64 years) was compared with age- and sex- matched healthy controls (n=75). The micronutrients were calculated as per the Nutritive value of Indian Foods given by the National Institute of Nutrition, Indian Council of Medical Research, India and the US dietary intake guidelines as applicable. It was found that the Body Mass Index (BMI) of patients was significantly lower than that of healthy controls. The total intake in terms of calorie was lower in patients when compared to controls. The dietary intake of vitamin E, riboflavin, choline, magnesium, copper manganese and sulfur was significantly lower than that of controls as well as the Recommended Dietary Allowance (RDA). Dietary intake of selenium and vitamin C was within the limits of the RDA but was lower than that of controls, while the intake of carotene was similar in both the groups and met the RDA. We conclude that patients with CP had significantly decreased micronutrient intake owing to diet modification due to pain. Micronutrient deficiency might contribute to increased oxidative stress in these patients.
