RESUMO

We report 3 cases of acute hepatitis A infection with haematological manifestations. In the first case, severe aplastic anemia occurred in a 6 year-old child, who underwent 3 bone marrow grafts before responding favourably. In the second and third cases, severe anemia and thrombocytopenia occurred in a 42 year-old man with cholestatic hepatitis, and in a 66 year-old man with fulminant hepatitis; there was a favourable outcome in both cases. These cases demonstrate that haematological manifestations in hepatitis A can be severe, independent of the severity of liver disease. Although these manifestations seem to be rare, we suggest performing systematic haematological evaluations in cases of viral hepatitis A with unusual outcomes.

RESUMO

We report the case of the association of three uncommon diseases in a young woman: incontinentia pigmenti, portal hypertension due to hepatoportal sclerosis, and liver adenomatosis. Incontinentia pigmenti is a hereditary genodermatosis with pigmentary cutaneous lesions and dysmorphic malformations. In our patient, among liver abnormalities, there were blood biochemical alterations, portal hypertension, and initially neo hepatic nodular lesions. Histological examination of the surgical liver specimen showed several adenomas and fibrosis of the portal tracts with portal vascular changes. The etiopathogenic nature of the adenomatosis and hepatoportal sclerosis is unclear. As a general rule, hepatic adenomatosis is associated with normal liver. We hypothesize that the adenomas could be secondary to changes in hepatic vascularisation.

RESUMO

UNLABELLED: We report 5 cases of psychiatric side effects in patients treated with alpha interferon for chronic viral C hepatitis. The first case includes depression with suicidal impulses without a suicide attempt; there was a positive rechallenge of interferon. In the second and third cases, depression occurred during interferon therapy, but has not disappeared after interferon withdrawal. In the 4th and 5th cases, depression occurred after interferon withdrawal. Overall, suicide was attempted in 4 cases after interferon withdrawal and was responsible for 2 deaths. The prevalence of suicide attempts during the 6 to 12 months of interferon therapy was 0% compared to 1.3% during the 6 months after interferon therapy (P < 0.05) in 306 patients with chronic hepatitis C treated by interferon in our local area network during the same period. IN CONCLUSION: a) depression does not always disappear after interferon is discontinued; b) regular psychiatric follow-up is justified during treatment with interferon; c) psychiatric supervision should be continued, even more frequently after interferon withdrawal; d) the increased risk of psychiatric side-effect due to interferon as well as their severity suggest interferon should be administered with caution; e) the role of interferon can only be evaluated in controlled studies including the incidence and predictive value of emotional disorders.

RESUMO

AIMS: The aim of this study was to develop a technique to measure collateral blood flow in portal hypertensive rats. METHODS: Morphological techniques included inspection, casts and angiographies of portosystemic shunts. The main hemodynamic measurements were splenorenal shunt blood flow (transit time ultrasound method), percentage of portosystemic shunts and regional blood flows (microsphere method). In study 1, a model of esophageal varices was developed by ligating the splenorenal shunt. In study 2, morphological studies of the splenorenal shunt were performed in rats with portal vein ligation. In study 3, the relationship between splenorenal shunt blood flow with percentage of portosystemic shunts was evaluated in dimethylnitrosamine cirrhosis. In study 4, secondary biliary, CCl4 and dimethylnitrosamine cirrhosis were compared. In study 5, rats with portal vein ligation received acute administration of octreotide. In study 6, rats with dimethylnitrosamine cirrhosis received acute administration of vapreotide. RESULTS: Blood flow of para-esophageal varices could not be measured. SRS blood flow was correlated with the mesenteric percentage of portosystemic shunts (r = 0.74, P < 0.05), splenic percentage of portosystemic shunts (r = 0.54, P < 0.05) and estimated portosystemic blood flow (r = 0.91, P < 0.01). Splenorenal shunt blood flow was 6 to 12 times higher in portal hypertensive rats, e.g., in portal vein ligated rats: 2.8 +/- 2.7 vs 0.3 +/- 0.1 mL.min-1 in sham rats (P < 0.01), and was similar in the different cirrhosis models but was higher in portal vein ligated rats than in cirrhotic rats (1.2 +/- 0.7 vs 0.6 +/- 0.6 mL.min-1.100 g-1, P = 0.05). Octreotide significantly decreased splenorenal shunt blood flow: -23 +/- 20% (P < 0.01) vs -6 +/- 8% (not significant) in placebo rats. The variation of splenorenal shunt blood flow after vapreotide was significant but not that of the splenic percentage of portosystemic shunts compared to placebo. CONCLUSIONS: The splenorenal shunt is the main portosystemic shunt in rats. The measurement of splenorenal shunt blood flow is easy, accurate and reproducible and should replace the traditional measurement of the percentage of portosystemic shunts in pharmacological studies.

RESUMO

INTRODUCTION: We report the occurrence of non-Hodgkin's lymphoma during the course of chronic hepatitis C treated with alpha-interferon. EXEGESIS: Specific viruses such as Epstein-Barr virus and human T-cell leukemia viruses I and II may be at the origin of various lymphomas in human. The presence of B cell lymphoma in the course of chronic hepatitis C has already been described and could be related to the lymphoid tropism of hepatitis C virus. CONCLUSION: This new report of an association between chronic hepatitis C and B cell lymphoma should lead physicians to search for signs of lymphoma in patients with chronic hepatitis C.

RESUMO

Bleeding stomal varices is a rare complication of portal hypertension. We report the case of a cirrhotic patient, with a history of colonic adenocarcinoma, who had recurrent bleeding stomal varices. Treatment with transjugular intrahepatic portosystemic shunt and stomal varice embolization was performed because failure of medical treatment of portal hypertension and sclerotherapy. Twenty six months later only one stomal hemorrhage was noted. This suggests that transjugular intrahepatic portosystemic shunt and stomal varice embolization is effective in case of recurrent bleeding of stomal varices.

RESUMO

Mucinous ectasia of the pancreas ducts is a recently described cystic lesion which usually occurs in acute pancreatitis. Endoscopic retrograde pancreatography provides diagnosis. Mucinous ductal ectasia is considered to be a precancerous lesion. Surgical exeresis is recommended. Our two cases emphasize the difficulties encountered for differential diagnosis with other cystic lesions of the pancreas.

RESUMO

BACKGROUND/AIMS: The action sites and kinetic effects of octreotide and terlipressin may be different. Therefore, we studied the hemodynamic effects of acute administration of these drugs alone or in combination in rats with portal hypertension due to portal vein ligation. METHODS: In a first study performed in anesthetized rats, hemodynamics were measured before and after drug administration (placebo, octreotide: 8 microg x kg(-1) x h(-1) for 30 min, terlipressin: 50 microg/kg bolus, terlipressin + octreotide at the same doses). The second study, performed in conscious rats, included the same groups and drug doses; hemodynamics were measured every 10 min for 1 h. The third study tested the effect of preinfusion of octreotide on responsiveness to terlipressin. RESULTS: Terlipressin produced more marked systemic effects than octreotide by decreasing heart rate and cardiac output and increasing mean arterial pressure. Terlipressin produced a greater decrease in portal pressure than octreotide: placebo: -3+/-5%, terlipressin: -42+/-8%, octreotide: -16+/-10%, combination: -44+/-8% (conscious rats at 20 min, p<10(-4)). The decrease in portal pressure was immediate and lasted at least 60 min with both drugs. Octreotide significantly decreased spleno-renal shunt blood flow (% variation): placebo: -6+/-8, terlipressin: -15.5+/-20, octreotide: -22.5+/-20, combination: -27+/-10 (p<10(-2)). Octreotide preinfusion significantly increased the responsiveness of arterial pressure and heart rate to terlipressin. CONCLUSIONS: Terlipressin decreases portal pressure significantly more than octreotide, while only octreotide significantly decreases collateral blood flow. Simultaneous administration of these drugs does not have significant additive effects but has complementary effects. The preadministration of octreotide alters systemic response to terlipressin.
