Spectrum of acute viral hepatitis and its clinical outcome--a study from Ludhiana, Punjab.

This study was carried out to find the etiological spectrum and clinical profile of acute viral hepatitis in Ludhiana. Hepatitis E was encountered most frequently (44.56%) followed by hepatitis B (29.7%), whereas hepatitis D occurred least frequently (0.99%). The age group most commonly affected was 20-30 years(32,67%) followed by 30-40 years (23.76%). Males showed higher incidence as compared to females in the ratio of 62.4:37.6. The most frequent clinical features were anorexia and jaundice. The disease was found to be more common in urban set up(78.2%) than in rural regions (21.8%). Mortality was mainly because of fulminant hepatitic failure. In 1.98% of cases, etiology remained undecided. Total bilirubin and prothrombin time were found to be useful prognostic indicators.

Epidemiology of hepatitis E and A in Ludhiana.

AIM: To study the epidemiology of hepatitis E and A in Ludhiana. METHODS: A retrospective analysis of laboratory data of the year 2001 was done, to study the epidemiology of hepatitis E and A in Ludhiana in relation to prevalence, age, sex, area of residence and seasonal variation. RESULTS: Prevalence of HEV was 13.9%. Infection with it occurred through out the year with no preponderance of cases following the monsoons. Young male adults between 20-40 years of age were predominantly affected. Prevalence of HAV was 5.5% affecting mainly children below 14 years of age. Population of urban areas around "Gandha Naliash" (a large open sewer) was at high risk as there was clustering of HEV & HAV cases around that area.

Transabdominal gastroesophageal devascularization without esophageal transection for emergency treatment of variceal hemorrhage.

BACKGROUND: The Suguira procedure is an effective non-shunting operation to treat life-threatening hemorrhage from esophageal or gastric varices. The goal of esophageal transection is interruption of submucosal varices, but this leads to high morbidity and mortality rates from esophageal fistulization. AIM: To evaluate a variant of this procedure in which the esophagus is not transected, but the varices are underrun from outside the lumen. METHODS: During the last four and a half years, we performed this modified gastroesophageal devascularization with or without splenectomy in 18 patients as emergency treatment of bleeding esophageal and gastric varices. The data were analyzed retrospectively. RESULTS: Bleeding was controlled in all patients. Three patients with Child's class C disease undergoing emergency surgery died during the early postoperative period. Rebleeding rate was 17% (3 patients). The overall survival was 72.2% (13 of 18). No patient had encephalopathy over a mean follow up of 30 months. CONCLUSION: Gastroesophageal devascularization with variceal under-running without esophageal transection is an effective and safe alternative to shunt surgery in the emergency situation.

Hepatic artery pseudoaneurysm and hemobilia following laparoscopic cholecystectomy.

Iatrogenic or accidental injury to the right hepatic artery or its branches can result in formation of pseudoaneurysm, which may rupture into the biliary system, leading to life-threatening hemobilia. We describe one such case following laparoscopic cholecystectomy and discuss its management.

Serum zinc levels in hepatic encephalopathy.

BACKGROUND: Zinc is essential for various metabolic processes of the body. Since serum zinc levels are lowered in liver diseases, it has been postulated to be a precipitating factor for hepatic encephalopathy. METHODS: We prospectively studied serum zinc levels in consecutive patients with fulminant hepatic failure, subacute hepatic failure and chronic liver disease with encephalopathy. Serum zinc levels were correlated with various clinical and biochemical parameters and final outcome of patients. Serum zinc levels were estimated by atomic absorption spectrometry at admission and also 24 hours after recovery in survivors. RESULTS: Of the 55 patients (age 17-65 years, 35 men) studied, 30 had acute, 5 subacute and 20 chronic liver disease. Patients with hepatic encephalopathy had significantly lower serum zinc levels as compared to 20 age and sex matched controls. High serum bilirubin levels and prothrombin time showed inverse relationship with serum zinc levels. There was no relationship of serum zinc levels with age, sex, grade and duration of encephalopathy, liver size, ascites or splenomegaly. CONCLUSIONS: Hepatic encephalopathy is associated with low serum zinc levels. Recovery occurred in 17 patients despite persisting low serum zinc levels. Serum bilirubin > 23 mg/dL and prothrombin time prolongation > 12 seconds above control have inverse correlation with serum zinc level.

Evaluation of culture techniques for detection of spontaneous bacterial peritonitis in cirrhotic ascites.

This prospective study was done in cirrhotic patients to evaluate ascitic fluid culture techniques by the conventional method and by an alternate method of bedside ascitic fluid inoculation into blood culture bottles, with an aim to improve bacteriological diagnosis of spontaneous bacterial peritonitis (SBP). Of the 300 patients who were evaluated, 43 who had a total leukocyte count greater than 500/mm3 or a polymorphonuclear cell count greater than 250/mm3 in ascitic fluid were included. There were 30 episodes of SBP in 28 patients and another 15 patients had culture-negative neutrocytic ascites (CNNA). Escherichia coli was the commonest organism cultured, being found in 60%. There was significantly greater (p < 0.001) ascitic fluid culture positivity with direct inoculation into blood culture bottles, i.e. 66.7% compared to 31.1% by conventional method at 48 hours, and this was evident even 24 hours after inoculation i.e. 33.3% positivity compared to 4.4%. Bacteremia was present in 53.3% of patients with SBP and 33.3% with CNNA. Ascitic fluid inoculation directly into blood culture bottles leads to a significantly increased percentage of culture positivity and reduces the time needed for detection of SBP from 48 to 24 hours.
