1021. Increased CA 125 in a patient with tuberculous peritonitis: case report and review of published works.
A case of a middle aged woman with weight loss, ascites, and a pleural effusion is presented where a clinical diagnosis of ovarian cancer was made. Her CA 125 was greatly increased at 873 IU/ml and the ascites was a lymphocytic exudate but cytology failed to show malignant cells. Operative biopsy showed numerous noncaseating granulomas in the omentum but no mycobacterial organisms were seen. Empiric antituberculous treatment was started before positive culture results were received and when treatment had ended both the ascites and pleural effusion had resolved and the CA 125 had fallen to 7 IU/ml. Review of published works showed several other examples of tuberculous peritonitis associated with increased CA 125 and the possible cause of raised CA 125 in this condition is discussed.
1026. Why portal hypertensive varices bleed and bleed: a hypothesis.
Continued bleeding or early rebleeding is associated with a poor prognosis in patients with variceal haemorrhage. It is not clear why bleeding stops in some patients and continues or restarts in others. It is suggested that secondary haemodynamic changes in the splanchnic circulation after a bleed may contribute to the risk of further bleeding. These changes include the effects of hypotension on portocollateral resistance, the effects of blood in the gut on splanchnic blood flow, and the effects of blood volume expansion on portal venous pressure during resuscitation. These factors, working in concert, cause a secondary rise in portal venous pressure, which may precipitate further bleeding. Treatment aimed at preventing these secondary haemodynamic changes may be beneficial. It is probable that somatostatin and octreotide could act in this way, which may explain their therapeutic efficacy.

Liver involvement in systemic amyloidosis is frequent but is rarely of clinical importance. Five patients with severe cholestatic jaundice are described and an additional 20 from published reports are reviewed. The most frequent presenting symptoms were lethargy and abdominal pain, which were present for a median of 11 months before the onset of jaundice. Hepatomegaly, usually marked, was present in 92%, with ascites in 56% of the cases. The serum bilirubin concentration was noticeably high and the serum globulin low. Histology of the liver showed considerable perisinusoidal deposition with a slight predilection for the periportal area. Two patients presented with predominant centrilobular deposition. Congo red staining was not uniformly positive. A variety of treatment regimens was tried but median survival was only three months from the onset of jaundice.
