Epidemiology and clinical pattern of hepatitis delta virus infection in Pakistan
Background and Aims: The global epidemiology of hepatitis delta virus (HDV) infection is changing. This study was performed to determine the epidemiology and clinical impact of hepatitis delta in Pakistan.Methods: Countrywide data was collected from 1994 to 2001. A total of 8721 patients were tested for hepatitis delta antibody. A subset of 97 hepatitis delta antibody reactive inpatients with chronic liver disease were compared to 97 patients admitted with liver disease due to hepatitis B alone.Results: Of the 8721 patients tested, 1444 (16.6%) were reactive for hepatitis delta antibody. Most were males (87.4%, P \u3c 0.001) and younger (mean age 31 years, P \u3c 0.001) compared to HDV non-reactive patients. Prevalence of delta infection was highest in the rural (range 25-60%) compared to the urban population (range 6.5-11%). Analysis of the inpatient data showed that delta infected patients had significantly less severe clinical liver disease and a trend towards lesser development of hepatocellular carcinoma compared to delta negative patients.CONCLUSIONS: (i) HDV infection is present in 16.6% of hepatitis B infected patients in Pakistan, most commonly in younger males living in rural areas; and (ii) delta virus infected patients have less severe clinical liver disease compared to delta negative, hepatitis B patients

Patients with Crohn's disease have longer post-operative in-hospital stay than patients with colon cancer but no difference in complications' rate
BACKGROUNDRight hemicolectomy or ileocecal resection are used to treat benign conditions like Crohn's disease (CD) and malignant ones like colon cancer (CC).AIMTo investigate differences in pre- and peri-operative factors and their impact on post-operative outcome in patients with CC and CD.METHODSThis is a sub-group analysis of the European Society of Coloproctology's prospective, multi-centre snapshot audit. Adult patients with CC and CD undergoing right hemicolectomy or ileocecal resection were included. Primary outcome measure was 30-d post-operative complications. Secondary outcome measures were post-operative length of stay (LOS) at and readmission.RESULTSThree hundred and seventy-five patients with CD and 2,515 patients with CC were included. Patients with CD were younger (median = 37 years for CD and 71 years for CC (P < 0.01), had lower American Society of Anesthesiology score (ASA) grade (P < 0.01) and less comorbidity (P < 0.01), but were more likely to be current smokers (P < 0.01). Patients with CD were more frequently operated on by colorectal surgeons (P < 0.01) and frequently underwent ileocecal resection (P < 0.01) with higher rate of de-functioning/primary stoma construction (P < 0.01). Thirty-day post-operative mortality occurred exclusively in the CC group (66/2515, 2.3%). In multivariate analyses, the risk of post-operative complications was similar in the two groups (OR 0.80, 95%CI: 0.54-1.17; P = 0.25). Patients with CD had a significantly longer LOS (Geometric mean 0.87, 95%CI: 0.79-0.95; P < 0.01). There was no difference in re-admission rates. The audit did not collect data on post-operative enhanced recovery protocols that are implemented in the different participating centers.CONCLUSIONPatients with CD were younger, with lower ASA grade, less comorbidity, operated on by experienced surgeons and underwent less radical resection but had a longer LOS than patients with CC although complication's rate was not different between the two groups
