Roles of syndecan-1, bcl6 and p53 in diagnosis and prognostication of immunoproliferative small intestinal disease.

AIM: To evaluate roles of syndecan-1, bcl6 and p53 in diagnosis and prognostication of immunoproliferative small intestinal disease (IPSID) and to study profiles of kappa (kappa) and lambda (lambda) light chains and IgA heavy chain. METHODS: The study consisted of 11 cases of IPSID and similar number of controls which included 11 of normal intestinal mucosa and 11 of high grade B cell lymphoma of ileum. The parameters analyzed included clinical profiles, biochemical and other laboratory investigations, radiologic and histological findings including immunohistochemistry. RESULTS: All IPSID cases had demonstrable serum IgA heavy chain and heavy mucosal plasma cell infiltration. According to Galian's histological staging, there were 4 patients with stage A and 7 with stage B. kappa and lambda light chains were over-expressed in 7 patients; 1 stage A patient had H pylori-positive active gastritis and eradication of H pylori led to disease remission. Stage A biopsies had higher expression for syndecan-1, while stage B had higher expression for bcl6 and p53. Syndecan-1, kappa and lambda light chains and IgA heavy chain showed inverse relationship with bcl6 and p53. All patients were treated with doxycycline. CHOP regime was added in 5 patients who developed frank lymphoma. Three died of the disease due to extensive organ infiltration. CONCLUSION: Certain immunomarkers like syndecan-1, kappa and lambda light chains and IgA heavy chain could be of much help in identifying early stage IPSID. Stage B IPSID showed higher expression for bcl6 and p53 than stage A IPSID. bcl6 and p53 expressions correlated with a more advanced disease stage and aggressive tumour behavior.

Effect of different oral doses of isoniazid-rifampicin in rats.

UNLABELLED: Hepatotoxicity is one of the most serious adverse effects of antituberculosis drugs. The aim of this study was to produce a rat model of isoniazid-rifampicin (INH-RIF) induced hepatotoxicity. MATERIALS AND METHODS: Wistar rats (100-150 g) were treated with different doses of INH i.e. 25, 50 and 75 mg/kg/day with a fixed dose of RIF i.e. 50 mg/kg/day intragastrically for a period of 28 days. Serum glutamate oxaloacetate aminotransferase (SGOT), glutamate pyruvate aminotransferase (SGPT), bilirubin (Bil) and alkaline phosphatase (ALP) were estimated at 0,14, 21 and 28 days in rats. Histological analysis was carried out to assess the liver. RESULTS: Treatment of rats with INH-RIF (50 mg/kg/day each) induced hepatotoxicity as judged by elevated serum SGPT, SGOT, Bil and ALP as compared with their base line. Histological evaluation of INH-RIF induced hepatotoxicity also showed liver damage. CONCLUSION: The present study suggests that 50 mg/kg/day each of INH-RIF was selected as hepatotoxic dose (i.e. minimum dose with maximum hepatotoxicity) in wistar rats.

Causal role of Helicobacter pylori infection in gastric cancer: an Asian enigma.

Helicobacter pylori (H pylori) has been etiologically linked to gastric cancer.H pylori infection is more frequent in less developed Asian countries like India, Bangladesh, Pakistan,and Thailand and is acquired at early age than in more developed Asian countries like Japan and China. Frequency of gastric cancer, however, is very low in India, Bangladesh, Pakistan and Thailand compared to that in Japan and China. Similar enigma has been reported from Africa as compared to the West. Seroprevalence of H pylori infection in adult populations of India, Bangladesh, Pakistan and Thailand varies from 55% to 92%. In contrast, seroprevalence of H pylori in Chinese and Japanese adults is 44% and 55%,respectively. Annual incidence rate of gastric cancer in India, Bangladesh, and Thailand is 10.6, 1.3, 7.1 per 100,000 populations, respectively; in contrast, that in China and Japan is 32-59 and 80-115 per 100,000 populations, respectively. Several studies from India failed to show higher frequency of H pylori infection in patients with gastric cancer than controls. Available evidences did not support difference in H pylori strains as an explanation for this enigma. Despite established etiological role of H pylori, situation is somewhat enigmatic in Asian countries because in countries with higher frequency of infection,there is lower rate of gastric cancer. Host's genetic make-up and dietary and environmental factors might explain this enigma. Studies are urgently needed to solve this issue.

Effect of garlic on isoniazid and rifampicin-induced hepatic injury in rats.

AIM: To evaluate the hepatoprotective effect of garlic on liver injury induced by isoniazid (ZNH) and rifampicin (RIF). METHODS: Wistar rats weighing 150-200 g were treated orally with 50 mg/kg of INH and RIF daily each for 28 d. For hepatoprotective studies, 0.25 g/kg per day of freshly prepared garlic homogenate was administered orally half an hour before the INH+RIF doses. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and bilirubin were estimated on d 0, 14, 21, and 28 in all the rats. Histological analysis was carried out to assess the injury to the liver. Lipid peroxidation (LPO) as a marker of oxidative stress and non-protein thiols (glutathione) for antioxidant levels were measured in liver homogenate. RESULTS: The treatment of rats with INH+RIF (50 mg/kg per day each) induced hepatotoxicity in all the treated animals as judged by elevated serum ALT, AST, and bilirubin levels, presence of focal hepatocytic necrosis (6/8) and portal triaditis (8/8). Garlic simultaneously administered at a dose of 0.25 g/kg per day prevented the induction of histopathological injuries in INH+RIF co-treated animals, except in 4 animals, which showed only moderate portal triaditis. The histological changes correlated with oxidative stress in INH+RIF treated animals. The group which received 0.25 g/kg per day garlic homogenate along with INH+RIF showed higher levels of glutathione (P<0.05) and low levels of LPO (P<0.05) as compared to INH+RIF treated group. CONCLUSION: Freshly prepared garlic homogenate protects against INH+RIF-induced liver injury in experimental animal model.

Clinical features of celiac disease in Indian children: are they different from the West?

OBJECTIVE: This study was designed to prospectively evaluate the clinical features of celiac disease (CD) in a large group of Indian children and to compare them with those from the West. PATIENTS AND METHODS: Over a period of 5 years, a total of 549 children (< or = 14 years) with a clinical suspicion of CD were evaluated. Their detailed clinical features, investigations, and follow-up data were recorded. Complete hemogram, endoscopic duodenal biopsy, and celiac serology were done in all of the cases. Celiac disease was diagnosed on the basis of modified European Society of Paediatric Gastroenterology, Hepatology and Nutrition criteria. RESULTS: Celiac disease was diagnosed in 300 children; 39 were excluded because of lack of follow-up or poor response to gluten-free diet. The remaining 210 had normal villous architecture and served as controls. The mean (+/- standard deviation) age of children with CD was 6.7 +/- 3 years, and the mean duration of symptoms was 3.5 +/- 2.5 years. The majority (84%) presented with diarrhea; other features were failure to thrive in 91%, anemia in 84%, wasting in 87%, and stunting in 60% of cases. Among the serological tests, the best results were obtained with tissue transglutaminase. On follow-up (19.4 +/- 15.5 months), symptoms subsided in all cases of CD with a significant weight and height gain. CONCLUSIONS: Indian children with CD present late, with a significant delay in diagnosis. The majority presents with classic symptoms of diarrhea, failure to thrive, and anemia. There is a need for increasing awareness to pick up the atypical forms of the disease.

Gall bladder emptying in patients with corrosive-induced esophageal strictures.

Ingestion of corrosive substances can lead to strictures of the esophagus and stomach. Cicatrization of the lower part of the esophagus can entrap vagal fibers in the process of fibrosis. The aim of the present study was to evaluate gallbladder dysfunction as a sequel to vagal damage in patients with corrosive-induced esophageal strictures. The cephalic phase of gallbladder emptying was stimulated by modified sham feeding according to the chew-and-spit method. Gallbladder volume was measured by ultrasonography using the ellipsoid method after an overnight fast and every 15 min for a period of 90 min after sham feeding in 22 patients and 10 controls. Mean fasting gallbladder volume was significantly greater in patients than in controls (22.09 +/- 9.78 vs. 14.61 +/- 4.42 ml; P = 0.025). After sham feeding the gallbladder ejection fraction was significantly lower in patients than in controls (32.86 +/- 17.21 vs. 49.40 +/- 7.86%; P = 0.007). Patients with cicatrization in the distal one-third of the esophagus had a greater basal gallbladder volume (24.57 +/- 9.2 ml) and significantly lower ejection fraction (20.47 +/- 8.9%) than patients with strictures at other sites (gallbladder volume, 18.50 +/- 10.69 ml; ejection fraction, 47.48 +/- 13.3%; P = 0.001). In conclusion, patients with corrosive-induced esophageal strictures, especially those in the distal one-third, had an increased fasting gallbladder volume and decreased cephalic phase of gallbladder emptying, pointing to impaired vagal cholinergic transmission, possibly due to vagal entrapment in the cicatrization process.

Band ligation plus sclerotherapy versus sclerotherapy alone in children with extrahepatic portal venous obstruction.

Although endoscopic band ligation (EVL) plus sclerotherapy (EST) has shown to be superior to any individual method, there is no study in children. We therefore analyzed our experience of EST and EVL + EST in children with extrahepatic portal venous obstruction (EHPVO). Over a period of 8 years, 136 children who presented with a history of recent variceal bleeding due to EHPVO were studied; 30 of them received EVL + EST and 106 received EST alone. In the EVL + EST group, after the first session of EVL, EST was done three times weekly until variceal eradication was achieved. The mean age of these children was 7 +/- 3.6 years with a male-to-female ratio of 2.6:1. The rate of eradication was comparable in both groups (100% in EVL + EST and 96% in EST). However, EVL + EST group required a significantly fewer sessions and lower volume of sclerosant (2 +/- 1 vs. 4.4 +/- 2 sessions, P < 0.001 and 3.1 +/- 2 mL versus 7.5 +/- 4 mL, P < 0.001 respectively). There were significantly less complications in EVL + EST group (10% vs. 36%, P < 0.01). Over a mean follow-up of 27 months, varices recurred in 6.6% and 10% cases, respectively. EVL + EST is a better method in the treatment of esophageal varices in children with EHPVO than EST alone, as it required fewer session and had fewer complication.

Epidemiology of typhoid carriers among blood donors and patients with biliary, gastrointestinal and other related diseases.

Enteric fever due to Salmonella Typhi is a major public health problem. Typhoid carriers have high titres of Vi agglutinins in their sera. We worked out the baseline data for Vi agglutinins from 705 healthy blood donors (controls) by ELISA and compared it with 446 patients with biliary, gastrointestinal and other related diseases (cases). The samples were divided into five groups based on the disease condition of the patients from whom they were collected. Group A (n=196) consisted of patients with stones in the gall bladder/common bile duct and Group B (n=27) with gall bladder carcinoma. Group C (n=33) comprised patients with carcinoma of the pancreas/ampulla, obstructive jaundice and/or cholangiocarcinoma. Group D (n=112) had patients with acute/chronic pancreatitis, abdominal pain, intestinal obstruction, peritonitis, carcinoma oesophagus, chronic diarrhoea, gastrointestinal bleeding and dyspepsia. Group E (n=78) included patients with miscellaneous diseases. The mean absorbance value obtained for healthy subjects +3 standard deviations was taken as the cut-off value for a positive typhoid carrier. In Group A, 10.2% samples were positive; in Group B, 7.4%; in Group C, 12.0%; in Group D, 9.8% and in Group E, 9.0%. There was a highly significant (P <0.001) increase in the presence of Vi agglutinins in the cases compared to the controls. High prevalence of typhoid carriers occurs in patients with biliary, gastrointestinal and other related diseases. Vi serology employing highly purified Vi antigen offers a practical and cost-effective way of screening for S. Typhi carriers.

Clostridium perfringens type A & antibiotic associated diarrhoea.

BACKGROUND & OBJECTIVE: Clostridium perfringens type A (CPA) isolates produce lethal necrotizing antigens and the heat resistant forms of the organism are associated with pathogenic outcome in humans. CPA has also been implicated in antibiotic associated diarrhoea (AAD). We therefore undertook this study to investigate the presence of CPA in stool samples of patients with AAD in a tertiary care setting in north India. METHODS: A total of 285 stool samples obtained from patients suspected for Clostridium difficile aetiology were examined for the presence of CPA antigens. Four sets of reagents (CP-I, CP-II, CP-III and CP- IV) comprising latex beads coated with polyvalent immune sera to 17 serotypes of heat resistant CPA were used in the study. Agglutination reaction was carried out using the reagents with the stool supernatants. RESULTS: Of the 285 stool samples tested, 25 (8.77%) were positive for at least one or more of the four polyvalent sets. Briefly, 48 per cent were positive for all the four sets, 12 per cent for 3 sets, 28 per cent for 2 sets and 12 per cent for only one set, indicating the prevalence of multiple serotypes of CPA. Twenty three (92%) of the 25 positive samples came from patients who were on antibiotics. C. difficile toxin was also present in 9 of 25 (36%) of the samples positive for CPA antigens. INTERPRETATION & CONCLUSION: In our setting, CPA could thus be associated with AAD either by itself or in synergy with C. difficile infection. Assessment of true burden of CPA associated AAD would be required to take appropriate steps for its control in our country.

Prevalence of Salmonella enterica serovar typhi in bile and stool of patients with biliary diseases and those requiring biliary drainage for other purposes.

Acute suppurative cholangitis is a serious complication of biliary obstructions due to infection. Salmonella enterica serovar Typhi is an important biliary pathogen. Bile samples from 445 patients with biliary diseases as well as those requiring biliary drainage for other miscellaneous gastrointestinal diseases were investigated bacteriologically with special emphasis on Salmonella. Fecal samples or rectal swabs were also obtained from 402 of these patients. Bactericholia was detected in 68.8% patients and Salmonella in 5.8% of all bile samples. Other strains of salmonellae were also present in a fair number of the samples. Some of the patients had the same type of bacterial isolates from their stool samples as those from their bile samples. Colonization of the biliary system may not be clinically apparent, but is associated with an increased risk of infection.

Duodenal gastric metaplasia and Helicobacter pylori infection in high and low duodenal ulcer-prevalent areas in India.

BACKGROUND: Previous reports, based on surgery, showed duodenal ulcer (DU) to be more common in the rice-eating areas of southern India than in the northern wheat-eating areas. AIMS: Does this difference persist? Can it be explained by risk factors other than diet? METHODS: A total of 20 053 records from patients undergoing endoscopy for dyspepsia, and 590 endoscopy patients from two northern and two southern centers in India were studied prospectively. Records were scrutinized to determine the relative incidence of DU and non-ulcer dyspepsia in wheat- and rice-eating areas. Age, sex, length of history, smoking and medication were recorded. Three antral biopsies and one from each duodenal quadrant were taken. A rapid urease test was carried out on one of the antral biopsies; the others were examined for Helicobacter pylori, gastritis, duodenitis and duodenal gastric metaplasia. RESULTS: The difference in diet-associated prevalence persisted. No differences in smoking, Helicobacter pylori infection or duodenal gastric metaplasia were found between the two regions, but all three were more common in DU than in non-ulcer dyspeptic patients from both dietary areas. CONCLUSIONS: The dietary differences between the regions remain the only factor to account for the differences in DU prevalence. A strong interrelationship between duodenal gastric metaplasia and cigarette smoking is demonstrated.

Frequency of gastropathy and gastric varices in children with extrahepatic portal venous obstruction treated with sclerotherapy.

BACKGROUND: There are limited reports of the effect of endoscopic sclerotherapy (EST) on portal hypertensive gastropathy (PHG) and gastric varices (GV) in children with extrahepatic portal venous obstruction (EHPVO). We have studied the prevalence of PHG and GV in children with EHPVO and assessed the effect of EST on them on long-term follow-up. METHODS: From January 1992 to June 2002, consecutive children presenting with variceal bleeding due to EHPVO were included in this study. All children underwent EST at presentation and at 2-3 week intervals thereafter. During each session of endoscopy, gastric mucosa and fundus of the stomach was screened carefully to detect PHG and GV. Gastric varices were classified as gastroesophageal (GOV) and isolated gastric varices (IGV). RESULTS: In total, 274 cases of EHPVO were managed during the study period. The mean age was 7.4 +/- 3.5 years with a male to female ratio of 2.3:1. Of these 274 cases, 186 completed the EST program (study population), 60 were lost to follow-up, five died and 23 underwent surgery. At presentation (n = 274) 27% cases had PHG (3.6% severe) and 68.6% had GV (GOV 66.8%, IGV 1.8%). Following EST (n = 186) there was a significant (P < 0.001) decrease in GOV (45% from 64%) but an increase in IGV (14% from 1%) and PHG (51.6% from 24.7%). There was also a significant increase in severe PHG (15.6% from 3.2%, P < 0.05). On follow-up (mean follow-up 38 +/- 30 months) 19% children with IGV bled while none with PHG bled. CONCLUSIONS: Portal hypertensive gastropathy and gastric varices are quite common in children with EHPVO. Following EST, there is a chance of developing isolated gastric varices.

Ursodeoxycholic acid-augmented hepatobiliary scintigraphy in the evaluation of neonatal jaundice.

UNLABELLED: Early differentiation of extrahepatic biliary atresia from intrahepatic cholestasis is important. Hepatobiliary scintigraphy is an excellent noninvasive investigation for ruling out extrahepatic biliary atresia. This study aimed at identifying the role of ursodeoxycholic acid (UDCA), a choleretic agent, in conjunction with hepatobiliary scintigraphy in differentiating extrahepatic biliary atresia from neonatal hepatitis. METHODS: Fifty-one infants (42 male, 9 female) aged 0.3-5.5 mo (mean, 2.9 mo) presenting with neonatal jaundice underwent 99mTc-mebrofenin hepatobiliary scintigraphy. For patients who did not show any excretion of tracer into the intestine till 24 h, the study was repeated after oral administration of UDCA (20 mg/kg every 12 h) for 48-72 h. Ultrasonography and, if required, liver biopsy and intraoperative cholangiography were used with clinical data such as stool color and serologic and other etiologic investigations to form a final diagnosis. RESULTS: Of 51 patients, 19 showed biliary excretion in the first study, ruling out extrahepatic biliary atresia. Neonatal hepatitis was the final diagnosis in these. Of the remaining 32 patients, 12 nonexcretors converted to excretors after UDCA treatment, whereas 20 still showed no biliary drainage. Four nonexcretors on scintigraphy had a final diagnosis of neonatal hepatitis with galactosemia; the remaining 16 had extrahepatic biliary atresia. The specificity of hepatobiliary scintigraphy in ruling out extrahepatic biliary atresia improved from 54.3% to 88.6% (P < 0.001) after UDCA treatment. None of the patients experienced any ill effects from UDCA administration. CONCLUSION: Pretreatment with UDCA significantly improves the specificity of hepatobiliary scintigraphy in ruling out extrahepatic biliary atresia as a cause of prolonged neonatal jaundice.

Bacteriuria in patients with gallbladder and biliary tract diseases.

Urinary tract infections (UTI) are important hospital acquired entities, resulting in bacteriuria indicated by the presence of significant numbers of bacteria in the urine. This study examined the prevalence of bacteriuria in our patients with gallbladder diseases. Three hundred and forty eight patients with various gallbladder (GB) diseases were enrolled in our study. Routine bacteriological cultures of midstream urine specimens were done. Significant bacteriuria was defined as the growth of 105 or more organisms in pure culture per milliliter of urine. Forty four (12.6%) of the patients (18 symptomatic; 26 asymptomatic) showed bacteriuria. Escherichia coli was the predominant isolate followed by Klebsiella pneumoniae, Enterobacter, Pseudomonas aeruginosa, Enterococci and several others. Thus UTI is also a frequent concomitant of gall bladder diseases and is a sign of the fact that kidneys are in a condition endangered by pyelonephritis.

Pleuropulmonary complications of esophageal variceal sclerotherapy with absolute alcohol.

BACKGROUND: Esophageal variceal sclerotherapy (EVS) is an effective means of controlling variceal hemorrhage. However, it causes a wide variety of local and systemic complications. The present study was performed to document pleuropulmonary complications of EVS with absolute alcohol. METHODS: Twenty-six patients of portal hypertension of different etiologies were subjected to EVS with absolute alcohol. Baseline arterial blood gas analysis (PaO2, PaCO2, pH, HCO3, SaO2), chest X-ray and pulmonary function tests (forced expiratory volume at 1 s (FEV1), forced expiratory vital capacity (FVC), FEV1/FVC, maximum mid-expiratory flow rate (MMFR), and peak expiratory flow rate (PEFR)) were performed 4-6 h before the first session of EVS. These investigations were repeated within 24 h of EVS. Patients were asked to maintain a symptom diary and to record symptoms such as fever, chest pain, dysphagia and dyspnea during the study period. RESULTS: Ten patients (38.46%) had chest pain and four patients (15.68%) had fever after sclerotherapy. Eight patients (30.54%) complained of dyspnea and six patients (23.08%) developed pleural effusion. There was a significant decline in FVC and FEV1 after EVS as compared with baseline values. However, FEV1/FVC ratio, MMFR and PEFR did not have any significant change. CONCLUSIONS: Chest pain (38.46%), dyspnea (30.54%) and fever (15.68%) were the common symptoms after EVS while chest X-ray showed pleural effusion in 23.08%. Pulmonary function tests revealed a significant decline in FEV1 and FVC without change in FEV1/FVC ratio after EVS, suggesting a restrictive type of defect.

Concurrent pancreatic ductal changes in alcoholic liver disease.

BACKGROUND: Alcohol is a common etiological factor in both liver disease and chronic pancreatitis, but in a single individual it does not usually produce clinically significant disease in both organs. We assessed the prevalence of pancreatic ductal changes in patients presenting with alcoholic liver disease of different stages. METHODS: Forty-six patients with alcoholic liver disease were included in the present study. Liver biopsy was performed in patients with normal coagulogram. Endoscopic retrograde pancreatogram was performed in all patients and changes in chronic pancreatitis were noted. RESULTS: Of the 46 patients with alcoholic liver disease, 31 had cirrhosis of the liver, nine had fatty liver and two patients had alcoholic hepatitis. Twenty (43.47%) patients had features of chronic pancreatitis on endoscopic retrograde pancreatogram and these consisted of minimal pancreatitis changes in 10 patients, moderate changes in nine patients and advanced changes in one patient. There was no difference in the prevalence of pancreatitis changes in cirrhotics in comparison to non-cirrhotics. There was no correlation between the amount and length of alcohol intake and changes in pancreatitis. CONCLUSION: Pancreatic ductal changes on endoscopic retrograde pancreatogram are common in patients with alcoholic liver disease.

Endoscopic sclerotherapy in children: experience with 257 cases of extrahepatic portal venous obstruction.

BACKGROUND: Endoscopic sclerotherapy often is used to treat variceal bleeding in children with extrahepatic portal hypertension, but published data are limited. The role of endoscopic sclerotherapy in a large number of children with extrahepatic portal hypertension was evaluated. METHODS: Consecutive children presenting with variceal bleeding because of extrahepatic portal hypertension were included in this study. All children underwent endoscopic sclerotherapy with absolute alcohol at presentation and at 2-week to 3-week intervals thereafter, until variceal eradication was achieved. Follow-up endoscopy was performed at 3 months after eradication and then every 6 months thereafter. RESULTS: A total of 257 patients with extrahepatic portal hypertension were managed from January 1992 to December 2001. Of these, 50 were lost to follow-up before eradication was achieved, leaving 207 patients (144 boys, 63 girls; mean age at presentation, 7 [SD 3.5] years) for whom evaluation was complete. Of the 207 patients, 5 died of bleeding, 23 underwent surgery, and 6 are still undergoing endoscopic treatment. Varices were successfully eradicated in 165 of 173 cases (95%) after a mean of 4.5 (1.9) endoscopic sclerotherapy sessions (mean volume of sclerosant, 8 [4] mL). Complications encountered were ulcer (17%), stricture (18%), and perforation (1.4%). Interval bleeding before eradication was encountered in 10.6% of cases. At a mean follow-up of 36 (29) months, varices had recurred in 17% patients, but only 3 of them had recurrent bleeding. CONCLUSIONS: Endoscopic sclerotherapy effectively eradicates varices in children with extrahepatic portal hypertension, with an acceptable complication rate. On long-term follow-up, recurrent bleeding after eradication is rare.
