Characterization of lymphocytic subsets and cytokine production in gastric biopsy samples from Helicobacter pylori patients.
BACKGROUND: This study characterized the phenotypic subsets of isolated gastric lymphocytes and the cellular immune response in cultured gastric biopsy specimens. METHODS: Endoscopy specimens from 40 Helicobacter pylori-positive and 40 H. pylori-negative patients were studied. a) Isolated gastric lymphocytes were analysed for CD4+, CD8+ T-lymphocyte subsets, activated T cells, and natural killer cells on a fluorescence-activated cell sorter, using monoclonal antibodies. b) The supernatant of cultured gastric biopsy specimens were assayed for interleukin (IL)-2, IL-4, and IL-6 levels. RESULTS: In H. pylori-positive patients there was (a) a decrease in CD4+/CD8+ T cells, no change in activated T cells, and an increase in natural killer cells, and (b) no change in IL-2 levels and a significant increase in IL-4 and IL-6 levels. CONCLUSIONS: There is an increase in CD8+ lymphocytes and natural killer cells, and the observed increase in IL-4 and IL-6 might be important in H. pylori-associated gastritis.

Spontaneous bacterial peritonitis in a patient with gastric carcinoma.
Spontaneous bacterial peritonitis (SBP) is classically described in patients with cirrhosis and nephrotic syndrome. However, SBP rarely occurs in patients with malignant ascites. We report a patient with gastric cancer with ascites, who developed SBP. Clinicians need to be aware of this complication in patients with malignant ascites.

Sclerotherapy in noncirrhotic portal fibrosis.
Endoscopic sclerotherapy has emerged as an effective and safe mode of treatment for long-term management of esophageal varices due to cirrhosis of liver and extrahepatic portal venous obstruction. There are few studies that have evaluated the role of sclerotherapy in the management of esophageal varices in patients with noncirrhotic portal fibrosis (NCPF). We report our results of long-term sclerotherapy in patients with NCPF. Seventy-two consecutive patients (men 29, women 43; age 32.9 +/- 11.8 years) with recurrent variceal bleeding due to NCPF were entered into the sclerotherapy program. Forty-eight patients received intravariceal absolute alcohol and 24 patients received intravariceal sodium tetradecyl sulfate (STD). Variceal obliteration was achieved in 65 (90.3%) patients with a mean of 5.7 +/- 3.0 (range 1-14) sessions. These patients were followed-up for a mean of 21.4 +/- 20.4 (range 1-96) months. Thirteen (17.3%) patients had episodes of upper gastrointestinal bleeding during sclerotherapy. Rebleed after obliteration was seen in 6 (9.2%) patients. Sclerotherapy was associated with a significant reduction in bleeding rate (bleeds per month per patient) during sclerotherapy and after obliteration of varices as compared to presclerotherapy period (P < 0.000001 for both). Recurrence of esophageal varices after obliteration was seen in 9 (13.9%) patients with reobliteration of varices in five patients in whom sclerotherapy was attempted. Complications including esophageal ulcer and stricture formation were seen in 18 (25%) and 4 (5.6%) patients respectively; strictures were restricted to patients who received absolute alcohol. Two (2.77%) patients died of massive upper gastrointestinal bleed during follow-up. We conclude that sclerotherapy is an effective and safe modality in the prevention of variceal bleeds in patients with NCPF.

Transhiatal oesophagectomy for benign obstructive conditions of the oesophagus.
BACKGROUND: Transhiatal oesophagectomy is an accepted approach for the treatment of carcinoma of the oesophagus. However, experience of this technique in benign diseases is limited. METHODS: Transhiatal oesophagectomy was done in 29 patients for benign oesophageal conditions including corrosive stricture (21), achalasia of the cardia (four), tuberculosis (one), mediastinal fibrosis (one), Crohn's disease (one) and peptic stricture (one). Dysphagia was the predominant symptom in all patients; strictures had all previously been dilated repeatedly. The stomach was used as an oesophageal substitute in 24 patients; in five with a scarred stomach due to damage by a corrosive agent, oesophagocoloplasty was performed. Resection and reconstruction were done in one stage in 25 patients; four with poor nutritional status had a two-stage procedure. RESULTS: There was no perioperative death. Complications encountered were recurrent laryngeal nerve palsy (six patients) which was mostly transient, anastomotic leak (seven) and stenosis (eight). Postoperative function of the intrathoracic stomach was satisfactory. CONCLUSION: Transhiatal oesophagectomy is a safe and satisfactory procedure for benign obstructive conditions of the oesophagus.

Western blot analysis of serological response in Helicobacter pylori in acid peptic diseases.
A prospective study was undertaken in 70 patients presenting with acid peptic disease with the objective of characterising the serological response to Helicobacter pylori and finding antigens specific for the serodiagnosis of H. pylori infection. H. pylori status was assessed by smear microscopy, rapid urease activity, culture and histopathology of endoscopic gastric antral biopsy specimens. Serological characterisation was carried out by using western blotting of various antigenic components of H. pylori and subsequent enzymatic detection of antibodies against them. Four reactive bands in the molecular weight range of 45-65 kDa were present in all subjects irrespective of H. pylori status. Four to six immunoreactive bands in the molecular weight range of 21-45 kDa were found only in patients with positive H. pylori status and histopathologically proven gastritis. These immunoreactive components may be valuable in specific immunodiagnosis of H. pylori infection.

Endoscopic management of pancreatic diseases.
Endoscopic management has recently been used for a variety of chronic pancreatic diseases. We used this approach in five patients with pancreatic diseases (calcific pancreatitis 2, pancreatic pseudocyst 3). Nasocystic drain was placed in a patient with pancreatic pseudocyst at the tail end of the pancreas; a 5 Fr stent was placed over 0.021"/0.035" guide wire in the main pancreatic duct in the others. All patients had relief of pain. Nasocystic drain led to resolution of pseudocyst, perisplenic collection and pleural effusion. Endoscopic treatment is safe and effective in various pancreatic disorders.

Primary sclerosing cholangitis: an experience from India.
Primary sclerosing cholangitis (PSC) is considered to be rare in India. The aim of the present study was to investigate the incidence, clinical profile and outcome of PSC seen in a tertiary care centre. Over a period of 10 years (July, 1984-June, 1994) 18 patients of PSC were diagnosed at cholangiography (14 patients by endoscopic retrograde cholangiopancreatography, two patients by percutaneous transhepatic cholangiography and two patients by both methods). The presence of secondary causes, such as choledocholithiasis, biliary tract surgery, congenital biliary tract anomalies, cholangiocarcinoma and pancreatic diseases, were excluded. These patients were evaluated retrospectively with respect to their clinical presentation, radiological findings, presence of associated idiopathic ulcerative colitis (IUC), treatment instituted and outcome. The mean (+/- s.d.) age at diagnosis of PSC was 39.0 (+/- 16.1) years with a male:female ratio of 1.57:1. Nine (50%) patients had associated IUC. The diagnosis of the IUC preceded that of PSC in all but one case. Fifteen (83.3%) patients had cholestatic jaundice at presentation, while three (16.7%) patients had asymptomatic rise of alkaline phosphatase. Three (16.7%) patients had recurrent cholangitis and five (27.8%) patients developed portal hypertension during the course of the disease. At cholangiography, intrahepatic radicles were involved in all and extrahepatic radicles in 12 (66.6%) cases. Patients were managed with steroids (n = 7), colchicine (n = 3), ursodeoxycholic acid (UDCA; n = 2) and methotrexate (n = 1), along with symptomatic measures. Mean duration of follow up available in 11 (61%) patients was 20.1 months (range: 1 month-8 years). Four (36.4%) patients died. Steroids and colchicine did not have any effect while the one patient on UDCA and one on methotrexate showed improvement. In conclusion, in India PSC does not seem to be a rare entity. Its clinical profile and outcome are somewhat similar to those seen in Western countries.

Endoscopic retrograde cholangiopancreatography in postcholecystectomy syndrome.
The study was aimed to determine the role of endoscopic retrograde cholangiopancreatography (ERCP) in patients with postcholecystectomy symptoms in respect to interval of presentation following cholecystectomy. 170 patients with postcholecystectomy symptoms and negative upper gastrointestinal endoscopy were evaluated using ERCP. One hundred and seventeen (75%) out of 156 patients with successful ERCP had one or more abnormalities seen at ERCP. Bile duct stones (55 patients), benign strictures of bile duct (27 patients) were the common lesions detected. A significantly higher (p < 0.001) positive diagnosis was possible at ERCP in patients presenting with jaundice (100%) as compared to those without jaundice (61.8%). Spectrum of causes among patients presenting in early post-operative period (< 1 month) was somewhat different from those presenting later. Bile duct ligature and biliary fistula were the predominant causes in the former group, while stones and benign strictures were commoner in the patients presenting late. Endoscopic sphincterotomy and stone removal was performed successfully in 25 out of 30 patients in whom it was attempted. ERCP was found to be a very useful procedure in the management of postcholecystectomy symptoms. Spectrum of underlying disease was different in patients presenting before 1 month following cholecystectomy as compared to those presenting later.

Pancrease divisum: five years' experience in a teaching hospital.
AIM: To study the frequency and significance of pancreas divisum. METHODS: Retrospective analysis of all pancreatograms carried out between July 1989 and June 1994. RESULTS: The 809 pancreatograms performed included 207 in patients with pancreatitis (acute 74, chronic 133), 330 with biliary disease, 238 with obscure abdominal pain and 34 with pancreatic malignancy. Of these, 30 patients (3.7%) were diagnosed to have pancreas divisum - 26 had type I variant, one had type II variant and three had type III variant. Accessory papillary cannulation was attempted in 10 patients; 8 were successful, with dorsal ductography confirming pancreas divisum in all of them. Two of these 8 patients had changes of chronic pancreatitis in the dorsal duct. The frequency of pancreas divisum in patients with pancreatitis (19 of 207, 9.2%) was significantly higher than in patients with biliary diseases and those with obscure abdominal pain (11 of 568, 1.9%; p < 0.001). CONCLUSIONS: Pancreas divisum is not an uncommon condition in India and its frequency in patients with idiopathic pancreatitis is higher than that in patients with other abdominal conditions. It should be looked for in any case of idiopathic pancreatitis.

A study of hepatitis delta virus infection in patients with acute and chronic liver disease from northern India.
To assess the prevalence of hepatitis delta virus (H delta V) in northern India, 204 adult patients with acute and chronic liver disease who were positive for hepatitis B virus (HBV) markers were screened for anti-H delta V antibody by enzyme-linked immunosorbent assay (ELISA). Anti-H delta V antibodies were positive in 29 (14.2%) patients. The incidence of H delta V infection was higher (21.4%) in patients with chronic liver disease when compared with those with acute viral hepatitis (10.7%) (P < 0.05). H delta V antibodies were positive in 16.6% of patients with fulminant hepatic failure (FHF) and in 25% of cases with hepatocellular carcinoma. Co-infections were significantly higher in acute hepatitis (80%), while superinfections predominated (66.7%) in chronic liver disease (P < 0.05). Our data show that H delta V is endemic in northern India and should be considered a major health problem.

Assessment of optimal dose of lactose for lactose hydrogen breath test in Indian adults.
To evaluate the possibility of using a 12.5 g or 25 g oral dose of lactose for hydrogen breath test for diagnosis of lactose intolerance instead of the usual 50 g dose. 35 patients with non-ulcer dyspepsia and an abnormal 50 g lactose breath hydrogen of more than 20 ppm over the base line were retested using 12.5 g and 25 g lactose. 32 (91.4%) and 15 (42.8%) of these 35 patients had an abnormal hydrogen breath test using 25 g (p = ns compared to 50 g dose) and 12.5 g (p < 0.001) lactose doses respectively. This study reveals that it may be possible to use a 25 g lactose dose instead of a 50 g dose for the lactose hydrogen breath test.
