The aetiology of acute hepatitis in Taiwan: acute hepatitis superimposed on HBsAg carrier state as the main aetiology of acute hepatitis in areas with high HBsAg carrier rate.

The aetiology of sporadic acute hepatitis in Taiwan was studied in a consecutive series of 273 patients, 209 males and 64 females, aged from less than 1 to 73 years. Only eight patients (2.9%) had acute hepatitis A, 36 (13.2%) acute hepatitis B and 57 (20.9%) had acute non-A, non-B hepatitis (NANB). The remaining 172 patients (63.0%) were HBsAg positive but anti-HBc IgM negative and were classified as acute hepatitis in chronic HBsAg carriers. Age-specific analysis revealed that acute hepatitis types A and B accounted for 35% and 47%, respectively of acute hepatitis in patients below age 10, but their prevalence decreased dramatically with increasing age and remained quite low in patients over age 40. In contrast, acute hepatitis NANB occurred predominantly in the older patients. The prevalence of acute hepatitis NANB was 11 to 15% in patients below age 40, but increased gradually with increasing age thereafter. Of the patients over age 60, 58% had acute hepatitis NANB. Acute hepatitis in chronic HBsAg carriers accounted for 59 to 76% of acute hepatitis episodes in patients over age 10 and below age 60. Sex-specific analysis revealed that the prevalence of acute hepatitis A or B showed no significant sex difference, whereas acute hepatitis in chronic HBsAg carriers occurred predominantly in males and acute hepatitis NANB occurred predominantly in females. Of the acute hepatitis episodes in chronic HBsAg carriers about one-third was due to hepatitis Delta virus superinfection, while the remaining two-thirds were most likely acute exacerbations of the underlying hepatitis B virus infection and a few were due to non-A, non-B hepatitis superinfection.

A controlled study of glypressin versus vasopressin in the control of bleeding from oesophageal varices.

To evaluate the therapeutic effect of glypressin (triglycyl-lysine-vasopressin, C52H74N16O15S2.2C2H4O2.5H2O) in the treatment of oesophageal variceal bleeding, a randomized controlled trial of glypressin and vasopressin was conducted in 54 cirrhotic patients with oesophageal varices bleeding. Bleeding ceased within 24 h in 50% (13/26) of patients treated with glypressin and in 53.6% (15/28) of patients given vasopressin. Re-bleeding within 7 days occurred in 30.8% (4/13) of the glypressin group and in 20.0% (3/15) of the vasopressin group. There was no statistically significant difference in the therapeutic effect between glypressin and vasopressin. In the glypressin group, bleeding was more easily stopped in non-hepatocellular carcinoma (HCC) cirrhotic patients of Pugh's criteria A or B than in patients of Pugh's criterion C or HCC. We conclude that glypressin and vasopressin have similar therapeutic effect. In considering the application convenience, glypressin is an alternative to vasopressin in the treatment of bleeding varices in patients of good liver function reserve.

Low prevalences of HBV and HCV infection in patients with primary biliary cirrhosis in Taiwan: a case control study.

To study the role of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection in patients with primary biliary cirrhosis (PBC) against the background of HBV and HCV infection in the general population, serum specimens from a consecutive series of 27 patients with PBC and 108 age/sex matched 'healthy subjects' as control group were submitted to assays for hepatitis B surface antigen (HBsAg), antibody to hepatitis B core antigen (anti-HBc), antibody to hepatitis B surface antigen (anti-HBs) and antibodies to hepatitis C virus (anti-HCV). None of the patients with PBC were HBsAg or anti-HCV positive while 17 (15.7%) and 6 (5.6%) of 'healthy' controls were HBsAg positive and anti-HCV positive (P = 0.017 and 0.26). Patients with PBC also had a significantly lower prevalence of HBV infection than matched controls (70.4% vs 88.9%, P = 0.022). The results suggest that neither HBV nor HCV plays any significant role in the pathogenesis of PBC, and that PBC would not develop or be masked in patients with HBV or HCV infection.

A clinical study on pseudomyxoma peritonei.

To elucidate the clinical entity of pseudomyxoma peritonei, nine patients (male: female = 6:3) who had been treated in Chang Gung Memorial Hospital in the past 13 years were reviewed. The male patients with original appendiceal tumour were older than the male patients with original colon cancer or indefinite tumour (70, 67 and 67 years vs 42, 27 and 50 years). In addition, the former group survived in a disease-free status for 28 months on average, while the latter group died within 2 years. Echogenic ascites and diffuse low-attenuation intra-abdominal masses with scalloping on the surface of liver detected by ultrasonography and by computerized tomography, respectively, were found in most of the patients. Elevation of the serum carcinoembryonic antigen (CEA) during recurrence of the disease was also noted. This series suggested that: (i) the pre-operative diagnosis could be made with careful physical examination in conjunction with sonography or computerized tomography; (ii) the prognosis was better in patients with tumour of appendiceal origin; and (iii) serum CEA might be valuable for early detection of recurrence.
