Fifteen women with pseudo-LE syndrome were studied. The dissease is characterized by recurrent attacks of fever, myalgia, arthralgia, visceral manifestations (pericarditis, myocarditis, pleurisy, pleural effusion and lung involvement). A prominent feature was an abnormal liver function with elevated GOT and GPT levels in serum, and impaired bromsuophalein elimination. The incidence of varicosities and thrombophlebitis was markedly increased. There was a correlation between complement-fixing antimitochondrial antibody (AMA) titres and the degree of activity of the disease. A reverse correlation was observed between antimitochondrial antibody titres and the absolute lymphocyte count in peripheral blood. In all instances the antimitochondrial antibodies were of polyclonal origin, belonging mainly to immunoglobulin class IgG and, in a few patients, IgM, IgA, or IgD. AMA titres, lymphocyte counts in peripheral blood, sedimentation rate, serum iron level and alpha1- and alpha2-globulins proved to be valuable in following the course of the disease. Other values (C-reactive protein, alpha1-acid glycoprotein, immunoglobulin and beta1c-globulin in serum) were not helpful.

The feasibility of maintaining long-term viability of human venous allografts by cryopreservation has been investigated. Segments of vein were obtained from 85 patients undergoing a stripping operation for varicose veins. The venous segments were immersed in a dimethylsulfoxide 15% solution, deep frozen at -196 degrees C in liquid nitrogen and preserved for a duration of 1 week to 24 months. Light microscopy (n = 126) failed to demonstrate striking differences between control veins and any of the cryopreserved veins. The types of damage observed at scanning electron microscopy included endothelial cell separation, endothelial cell loss, exposed basement membrane and exposed fibrillar collagen, which were graded on a scale. The score for short term (less than 3 weeks) stored veins was 8.1 +/- 0.9 (mean +/- SEM) and did not differ from the long-term (greater than 10 weeks) stored veins score (6.3 +/- 1.0, p NS). The tissue enzymes LDH, GOT, GPT, CPK were measured in the frozen vein groups (n = 115) after thawing to room temperature. Cryopreservation did not alter any of the tissue enzymes measured when compared to controls. Endothelial fibrinolytic activity (FA) of 58 venous segments cryopreserved for a mean duration of 20 months was 6136.4 +/- 292.1 Tissue Activator Units (TAU) and did not differ from FA of 11 controls (5989.1 +/- 696.8 TAU). Synthesis of 6-Keto-PGF1-alpha-2, a stable breakdown product of PGI2, measured in 10 venous segments cryopreserved for 10 months, was significantly higher than in 13 veins stored in saline for 12 hours at 4 degrees C (2.8 +/- 0.4 vs 0.4 +/- 0.1 PG ml-1mg-1min-1, respectively; p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Data on blood lipids and liver function from 90 young women from a computer file on oral contraceptive users were analyzed. Subjects selected were 30 Bisecurin users, 30 Ovidon users, and 30 Anteovin users, aged 17-25, who had smoked 20 cigarettes/day or less. Triglycerides increased significantly (p0.001) at 1, 3 and 6 months for all groups. Total cholesterol also rose significantly for all groups at all time points. HDL rose significantly in Bisecurin and Anteovin users, and fell in the Ovidon group, at 6 months, and variable at other times. The liver enzymes GGT and GPT increased progressively, while AP fell. Laboratory values remained within normal limits. Varicose veins in 1 patient was the only complication. Side effects were listed with each pill formulation; Anteovin caused fewer side effects than the other pills.

We report the case of a young HIV seropositive patient with severe hemophilia A who presented rapid liver failure related to his chronic C hepatitis. The patient had been receiving factor VIII:C clotting factor concentrates (mean 60,000 U/year) since 1975. In 1984 alanine aminotransferase presented abnormal levels. The CD4 lymphocyte count in 1991 was normal and ultrasonographic scan showed normal liver morphology. In 1991 the patient were found to be seropositive for HCV antibodies as detected by the ELISA method and confirmed by the RIBA method. One year later, a progressive increase in policlonal gamma-globulin and a decrease in the CD4+ lymphocyte count to below 500/muL were detected in concomitance with ultrasonographic evidence of a progressive increase in the longitudinal diameters of the liver and spleen and signs of liver inhomogeneity. A significant inverse correlation was observed between the increase in the longitudinal diameter of the liver and the decline in albumin levels, and between the increase in the longitudinal diameter of the liver and the drop in platelet count. Elevated levels of ammonemia, gamma-glutamyl transpeptidase, alkaline phosphatase and IgA were detected. Moreover, decreased levels of the C4 and C3 complement fractions were documented. At this time (1994), esophagogram and esophagogastroscopy evidenced varicosities in the lower esophageal section (stage F1). The patient died in 1995 March at the age of 29 years of sudden septic shock related to Pseudomonas aeruginosa infection.

In a prospective study 40 perimenopausal women with climacteric complaints between 45 to 52 years of age were examined. Twenty three (100%) were assigned to treatment with hormonal replacement therapy (Climen fy Schering-estradiol valerate cyproteron acetate) for 6 months. The therapy had to be stopped in 5 women (22%) for side effects. The drug was contraindicated in 17 patients because of non-treated hypertension, varices, hepatopathy and uterine fibroids with repeated metrorrhagia. In 18 patients (78%) Climax score, ALT, AST, bilirubin, total cholesterol, HDL-Chol, LDL-Chol, triglycerides, haemogram, fibrinogen, APTT, Quick test, serum Ca2+ and P2+ and urine C2+ and P2+/24 hours, weight and arterial blood pressure before and after the treatment were examined. The results confirm the benefical effect of Climen on the Climax score (p < 0.0001), total cholesterol (p < 0.01), HDL-Chol (p < 0.05) and LDL-Chol (p < 0.0001). After administration of Climen a significant decrease of P2+ serum concentration was demonstrated. Climen is suitable for treatment of acute climacteric complaints and has benefical effects on lipid metabolism.

The authors performed a late evaluation of a distal splenorenal anastomosis minimum of five years following operation on 13 patients with schistosomiasis of the compensated liver-splenic type. The study of the anastomosis had been proven patent when the evaluation took place. Each patient underwent clinical, laboratorial, endoscopic and electroencephalographic assessment. The results demonstrated that no patient had shown any sign of recurrence of upper gastrointestinal hemorrhage. Among the endoscopic aspects, esophageal varices disappeared in 46.1% of the cases. There was reduction in the number, extent and volume of esophageal varices in 46.1%, 38.4% and 53.8% of the cases. Gastric varices disappeared in 91.6% of the cases. Only one patient (7.6%) had shown clinical and electroencephalographic signs of hepatic encephalopathy in the late final evaluation (non-significant). Only one patient (7.6%) had shown late postoperative ascites (non-significant). There were no significant alterations in serum levels of sodium, potassium, urea and creatinine in all the 13 patients. The values of indirect serum bilirubin increased in 92.3% of the patients. There was regression of splenomegaly in all 13 patients, as well as a significant improvement in their hematological values. There were no significant changes in the serum levels of aspartate aminotransferase and alanine aminotransferase or in the activity of the plasma prothrombin. The authors concluded that the distal splenorenal anastomosis became a protection factor against upper gastrointestinal hemorrhage and led to long-term improvement in the endoscopic aspects of esophagogastric varices, a significant improvement in the laboratorial aspects of hypersplenism and a marked reduction of splenomegaly with no significant changes in the hydroelectrolytic metabolism, renal function and hepatic function and had not compromised, long term, the quality of life of the majority of patients.

Background/Aim: Hepatic venography with a positive-contrast medium has been reported as a method for evaluating liver disease. However, the contrast medium used in this method provides insufficient portal vein observation and may cause severe liver injuries. Carbon dioxide (CO(2)), a negative-contrast medium, may be able to depict the portal vein system with minimal hepatic toxicity. The aim of this study was to evaluate the usefulness and side-effects of balloon-occluded hepatic venography with CO(2) (CO(2) venography) and to evaluate the correlation between retrograde portogram and liver function in patients with cirrhosis. Subjects and methods: The subjects consisted of 23 biopsy-proven cirrhotic patients (male:female, 16:7; age, 58+/-12 years, range 34-80). The causes of cirrhosis were alcohol intake in ten, HCV infection in ten, HBV infection in one, primary biliary cirrhosis in one and Budd-Chiari syndrome in one. Of these patients, six were complicated with hepatocellular carcinoma (HCC). CO(2) venography was performed with an occlusion balloon catheter, and 25 ml of CO(2) was infused. CO(2) portograms were scored as follows: 0, no visualization of portal veins; 1, visualization of peripheral portal branches; 2, unilateral first portal branch; 3, bilateral first portal branches; 4, main portal vein; 5, left gastric vein, superior mesenteric vein and splenic vein. Hepatic venous pressure gradient (HVPG), cardiac functions, biochemical analysis, blood gas analysis and oxygen (O(2)) saturation monitoring were measured simultaneously. Arterio-portography was also performed. To evaluate the usefulness of CO(2) venography in patients with HCC accompanied by portal vein tumor thrombus (PVTT), three patients were also examined. Results: No significant changes in ALT, AST, O(2) saturation or blood gas data were observed after CO(2) venography. A statistically significant positive correlation was observed between CO(2) portogram scores and Child-Pugh scores (r=0.68, P=0.003). The correlations between CO(2) portogram scores and HVPG, and the forms of gastroesophageal varices in patients without PVTT and major shunts were not significant. The CO(2) portogram score was significantly higher in patients with alcoholic liver cirrhosis than in those with HCV-positive cirrhosis (P=0.04). Cavernous transformation and peripheral portal branches were demonstrated in patients with HCC accompanied by PVTT. These findings could not be observed by arterio-portography. Conclusion: CO(2) venography to obtain retrograde portogram is a safe and useful method for evaluating the portal vein system and liver function in patients with liver cirrhosis.

Schistosomiasis mansoni is a widespread parasitic disease in the Brazilian territory that affects over 8 million individuals. Hepatosplenic schistosomiasis is a serious clinical presentation of this disease, associated with splenomegaly, liver fibrosis, and portal hypertension, and is responsible for approximately 7% of schistosomotic patients. The surgical treatment of portal hypertension in schistosomotic patients has distinct features when compared with cirrhotic patients, mostly because hepatic function is preserved in schistosomotic liver disease. Therefore, when attempting to reduce the portal pressure, the surgeon must be aware that the surgery might interfere with hepatic perfusion, and consequently with hepatic function. The aim of this study was to report the results achieved with splenectomy, division of the left gastric vein, devascularization of great gastric curvature, and postoperative endoscopic variceal sclerosis, as a surgical option to esophageal varices in hepatosplenic schistosomiasis. A total of 111 patients were studied, and the following is a list of inclusion criteria: age >16 years, history of gastrointestinal (GI) bleeding, presence of esophageal varices on preoperative endoscopy, hematocrit >22% and prothrombin enzymatic activity >50%, negative viral hepatitis on serologic tests (anti-HBV and anti-HCV), and definition, after liver biopsy, of exclusive schistosomotic liver disease. The following list includes exclusion criteria used: presence of liver disease other than schistosomotic, history of alcohol abuse, and preoperative thrombosis of the portal vein. The rebleeding rate was 14.4% during a mean 30-month follow-up period; portal vein thrombosis was 13.2%, and there was a global mortality of 5.4%. Gastric varices were present in 46.9% of the patients; for those patients, a gastrotomy and running suture of the varices achieved an eradication rate of the varices of 75.6%. The degree of periportal fibrosis was also analyzed. Periportal fibrosis staging revealed that patients with class II or III liver fibrosis had a significant increased risk of recurrent GI bleeding when compared with patients with class I liver fibrosis. Despite the elevation on alanine aminotransferase (ALT) and aspartate aminotransferase (AST), most other liver function tests showed no alteration or were corrected after surgery. We conclude that splenectomy, division of the left gastric vein, devascularization of great gastric curvature, and postoperative endoscopic variceal sclerosis showed good results globally and should be considered as therapeutic options in the treatment of hepatosplenic schistosomiasis.

Although various effects of therapy for gastric varices, a complication of portal hypertension, on portal hemodynamics have been suggested, the effects of the therapy on liver functions have not yet been clarified. The aim of this study was to examine the effects of endoscopic gastric variceal therapy on liver functions in patients with hepatic cirrhosis. The subjects were 18 hepatic cirrhosis patients with the complication of gastric varices, who could be monitored for a long term (at least 1-year after therapy). They consisted of patients receiving prophylactic treatments after being confirmed to have a risk of rupture of gastric varices (16 prophylactic cases) and those with a history of bleeding and receiving palliative treatments to prevent rebleeding (two palliative cases). To evaluate liver functions, blood tests before the therapy, just after the therapy and at 1, 3, 6 and 12 months after the therapy were retrospectively examined and the levels of albumin, total bilirubin (T.Bil), ALT, choline esterase (ChE), platelets and the Child-Pugh classification were assessed. The albumin levels tended to increase after the therapy, and the level at 6 months after the therapy was significantly higher than the pre-treatment value (P=0.0311). At 1 year after the therapy, the level was higher than the pre-treatment value, but there was no significant difference. The ChE level tended to decrease just after the therapy, but it tended to be increased at 3 and 6 months after the therapy. Although significant improvement was not seen in T.Bil, ALT, platelet levels or the Child-Pugh classification after the therapy, none of these worsened. Endoscopic gastric variceal ligation therapy significantly improved liver functions, or at least albumin synthesis.

Risk factors for the development of hepatocellular carcinoma (HCC) were investigated in 397 patients who underwent non-shunt operation for esophageal varices due to underlying cirrhosis or pre-cirrhosis between September 1979 and May 1995. Ninety-five of these patients developed HCC. The clinical characteristics of patients at the time of surgery for varices, stages (F0-F4) of the progression of fibrosis, and grades (A0-A3) of necroinflammatory activity in liver biopsy tissue obtained at surgery in 170 patients based on the New Inuyama Classification (Int. Hepatol. Commun. 6 (1996) 112), were analyzed to investigate their relationship with the development of HCC. In addition, the levels of AST and ALT were followed every 3 months after surgery in 116 patients, and were divided into 2 groups at 80 IU/ml to compare the level of risk for the development of HCC. In liver biopsy tissue, group F4 (n=68/152, 45%) showed a significantly higher (P=0.0224) rate of appearance of HCC than group F3 (n=3/18, 17%). Group F4 also tended to show a higher cumulative HCC appearance rate of 55% compared with 37% for group F3 at 10 years after surgery (P=0.097). In regard to activity, the appearance rate of HCC in group A2+A3 (n=52/112, 51%) was significantly higher (P=0.0008) than that of HCC in group A1 (n=14/58, 25%). The cumulative appearance rate (60%) of HCC in group A2+A3 was significantly higher than that (31%) in group A1 at 10 years after surgery (P=0.0003). The appearance rate of HCC was significantly higher in the group (n=33/44, 75%) with a mean AST level >/=80 IU/ml than in the group (n=41/72, 57%) with a mean AST level <80 IU/ml (P=0.0496). A multivariate analysis of the risk factors for the development of HCC showed that necroinflammatory activity was a risk factor. These results suggested that the histopathologic classification (the New Inuyama Classification) of liver biopsy tissue from patients who underwent non-shunt operation for esophageal varices due to underlying cirrhosis or pre-cirrhosis is useful for predicting the development of HCC, to which the grades of necroinflammatory activity in particular are more closely related.
