RESUMO

Liver steatosis is a main histopathological feature of Hepatitis C (HCV) infection because of genotype 3. Steatosis and/or mechanisms underlying steatogenesis can contribute to hepatocarcinogenesis. The aim of this retrospective study was to assess the impact of infection with HCV genotype 3 on hepatocellular carcinoma (HCC) occurrence in patients with ongoing HCV cirrhosis. Three hundred and fifty-three consecutive patients (193 men, mean age 58 ± 13 years), with histologically proven HCV cirrhosis and persistent viral replication prospectively followed and screened for HCC between 1994 and 2007. Log-rank test and Cox model were used to compare the actuarial incidence of HCC between genotype subgroups. The patients infected with a genotype 3 (n = 25) as compared with those infected with other genotypes (n = 328) had a lower prothrombin activity [78 (interquartile range 60-85) vs 84 (71-195) %, P = 0.03] and higher rate of alcohol abuse (48%vs 29%, P = 0.046). During a median follow-up of 5.54 years [2.9-8.6], 11/25 patients (44%) and 87/328 patients (26%) with a genotype 3 and non-3 genotype, respectively, develop a HCC. HCC incidences were significantly different among the genotype subgroups (P = 0.001). The 5-year occurrence rate of HCC was 34% (95% CI, 1.3-6.3) and 17% (95% CI, 5.7-9.2) in genotype 3 and non-3 genotype groups, respectively (P = 0.002). In multivariate analysis, infection with a genotype 3 was independently associated with an increased risk of HCC occurrence [hazard ratio 3.54 (95% CI, 1.84-6.81), P = 0.0002], even after adjustment for prothrombin activity and alcohol abuse [3.58 (1.80-7.13); P = 0.003]. For patients with HCV cirrhosis and ongoing infection, infection with genotype 3 is independently associated with an increased risk of HCC development.

RESUMO

PURPOSE AND METHODS: In order to evaluate the prevalence of positive hepatitis C virus (HCV) serology and cryoglobulinemia in human immunodeficiency virus (HIV)-infected patients, the prevalence and the clinical significance of cryoglobulinemia were prospectively studied in a cohort of 86 HIV-infected subjects seen as outpatients. They were compared to a control group consisting of 101 HIV-HCV+ patients being followed at the same hospital. RESULTS: HCV serology was positive in 53/86 (61.6%) patients, 25 (47.2%) of whom had detectable cryoglobulins in their sera although only 1 had clinical symptoms consistent with cryoglobulinemia. Cryoglobulinemia was also detected in 9/33 (27.3%) HCV- patients, with only one of them presenting clinical symptoms. Although the mean cryoglobulin concentration was lower for HIV+ patients than in controls (268 versus 585 mg/l, p < 0.01), their prevalence (39.5% and 27.2%, respectively) was higher (p < 0.03). CONCLUSION: Cryoglobulinemia is frequently detected in HIV-infected patients, regardless of their HCV serology, but is poorly correlated with clinical symptoms.

RESUMO

OBJECTIVE: Large-volume paracentesis associated with plasma volume expansion with albumin is an effective, safe, but costly therapy for ascites in patients with cirrhosis. The aim of this study was to compare the use of a synthetic plasma expander, hydroxyethyl starch (HES), with that of albumin. DESIGN: Sixty cirrhotic patients with ascites were studied. Patients were randomly assigned to be infused with either albumin (8 g/l of ascites removed, n = 33) or HES (200 ml/l of ascites removed, n = 27). None of the patients was treated with diuretics or had renal impairment or hyponatremia at entry. Clinical and laboratory data were obtained before and 1, 3 and 15 days after treatment. RESULTS: There were no significant differences in clinical and laboratory parameters between the two groups at entry into the study. None of the patients developed renal impairment during the trial. One patient (HES group) presented with hyponatremia. Plasma atrial natriuretic factor and aldosterone levels did not differ between the two groups at baseline or at 1 and 3 days after paracentesis. The volume of ascites removed did not differ between the albumin (7.9 +/- 4.4 l) and HES (6.9 +/- 5.3 l) groups. However, there was a significant difference in weight loss between the albumin and HES groups (7.9 +/- 5.2 kg vs 4.7 +/- 3.4 kg; p = 0.01). Clinical and laboratory parameters indicated that HES was well tolerated except for hypoalbuminemia. CONCLUSION: HES is well tolerated in patients with cirrhosis. There is no difference between HES and albumin in the prevention of complications related to large-volume paracentesis. The lesser degree of weight loss observed with HES needs further study.

RESUMO

Fourty-five patients, 28 men, 17 women (mean age 73 +/- 18 yrs) with rectal carcinoma underwent palliative endoscopic neodymium YAG laser therapy. Rectal hemorrhage ceased in 89 p. 100 of affected patients after 3 +/- 2 sessions and a normal rectal transit was restored in 80 p. 100 of affected patients after 3 +/- 1 sessions. Total destruction of intraluminal tumor was achieved in 40 p. 100 of patients after 4 +/- 1 sessions. Symptomatic improvement was more frequent in patients in whom total destruction of intraluminal tumor was achieved (p less than 0.01). Stepwise logistic regression selected 2 independent variables capable of predicting tumoral destruction: the kind of surgical contraindication, more often related to cancer extension (p less than 0.001) and a greater tumor length (p less than 0.03) in patients in whom destruction of intraluminal tumor was incomplete. Twenty-eight patients were subsequently treated after palliation was achieved. Cumulative probability of remaining improved at 6 months when treatment was not stopped was 40 p. 100 (confidence limits to 95 p. 100: 23 p. 100-59 p. 100). Five complications occurred, 3 rectovaginal fistulas and 2 stenosis.

RESUMO

The authors report a case of ulcerative colitis due to Histoplasma capsulatum in a previously healthy 35 year-old french geologist with acquired immune deficiency syndrome (AIDS). Gomori-Grocott and PAS stains and indirect immunofluorescence revealed Histoplasma capsulatum in colonic biopsies. The search for LAV antibody was positive. T-lymphocyte analysis revealed 10/mm3 OKT4 with OKT4/OKT8 ratio of 0.16. Histoplasmosis should be considered in subjects with ulcerative colitis according to the epidemiological context. In patients with AIDS relapses after discontinuation of treatment are to be expected and suppressive therapy with an imidazole derivative should probably be continued indefinitely.

RESUMO

This study was designed to evaluate the renal contribution to overall sympathetic nerve hyperactivity and the relationships between renal sympathetic activity and systemic, splanchnic or renal hemodynamics in a series of 55 cirrhotic patients. Plasma noradrenaline concentrations were significantly higher in the renal vein than in the pulmonary artery (803 +/- 54 vs 608 +/- 47 pg/ml, P less than 0.01). These two concentrations were significantly correlated, which suggests that renal sympathetic activity and overall sympathetic activity increase in parallel in patients with cirrhosis. However, the estimated renal net release of noradrenaline was not correlated with plasma noradrenaline concentration in the pulmonary artery, suggesting that overall sympathetic nerve activity is not directly dependent on renal contribution in patients with cirrhosis. Neither plasma noradrenaline concentration in the renal vein nor renal net release of noradrenaline were correlated with systemic. splanchnic or renal hemodynamics. Thus, this study did not show a major role of renal sympathetic activity in the hemodynamic changes in cirrhosis.

RESUMO

Plasma noradrenaline and adrenaline concentrations were measured in 75 patients with cirrhosis in order to attempt to correlate these concentrations and liver failure and hemodynamic changes. The increased noradrenaline concentration was not correlated with the degree of liver failure estimated by Pugh's classification, with the cause of cirrhosis, with the presence of acute alcoholic hepatitis or with the presence of ascites. Adrenaline concentration was higher in cirrhotic patients with acute alcoholic hepatitis than in those without these lesions. Noradrenaline concentration was significantly correlated with heart rate, wedged hepatic venous pressure and renal blood flow. Noradrenaline concentration was also negatively correlated with stroke volume and adrenaline concentration was negatively correlated with cardiac output and stroke volume. These findings confirm the relationships between portal hypertension, sympathetic hyperactivity and renal function in patients with cirrhosis.

RESUMO

Cystic dystrophy of the duodenal wall developing in heterotopic pancreas is a rare disease. Weight loss and painless vomiting due to duodenal stenosis where the main clinical manifestations of this entity in a chronic alcoholic patient. Diagnosis was made by using an ultrasonic-endoscope equipped with a miniprobe. Although surgical treatment is usually recommended in this situation, the clinical condition of this patient improved dramatically after subcutaneous injections of somatostatin analog (octreotide). This treatment was maintained during 9 months and no recurrence was observed during the follow-up period.

RESUMO

To determine whether tissue hypoxia occurred in cirrhosis, oxygen contents, mixed venous and hepatic venous lactate concentrations as well as systemic hemodynamics were studied in 53 patients with cirrhosis. The influence of liver failure on tissue oxygenation was also studied. Cardiac index and mixed venous and hepatic venous lactate concentrations were significantly higher in patients with cirrhosis than in 20 control subjects. Oxygen consumption, oxygen extraction ratio and mixed venous and hepatic venous carbon dioxide tensions were significantly lower in the former than in the latter. Oxygen transport was not significantly different between the two groups. Cardiac index and oxygen transport were not significantly different between grade A (Pugh's classification) and grade C patients. Mixed venous as well as hepatic venous lactate concentrations were significantly higher while oxygen consumption, oxygen extraction ratio and carbon dioxide tensions were significantly lower in grade C than in grade A patients. We conclude that tissue hypoxia occurs in patients with cirrhosis and hepatic insufficiency. This tissue hypoxia might be due to arteriovenous shunting-related limitation of tissue oxygen extraction.

RESUMO

The authors report two cases of peliosis hepatis, occurring in patients with AIDS, who presented a persistent fever and an hepatomegaly. The liver biopsies showed areas of peliosis, where bacilli were observed by Warthin-Starry stain. In one case, techniques of molecular biology allowed the identification of Rochalimaea henselae, pathogen involved in bacillary angiomatosis. This rickettsia has been newly recognized in the United-States, where 17 cases of bacillary peliosis have been published in immunocompromised hosts and mainly in patients with AIDS. These observations illustrate the clinical and histological features of this new opportunistic infection, as it is described in the literature. The clinical signs include an unexplained fever, an hepatomegaly, and in 75% of the cases, a splenomegaly. The cutaneous lesions of bacillary angiomatosis are associated in 40% of the cases. An antibiotic treatment by erythromycin ensures a complete recovery.

RESUMO

OBJECTIVES: Endoscopic sclerotherapy is effective to prevent bleeding of oesophageal varices but is associated with frequent adverse effects. Endoscopic ligation represents a new endoscopic alternative treatment to sclerotherapy. The purpose of this study was to assess efficacy and safety of endoscopic variceal ligation in 50 consecutive patients with cirrhosis who had recently bled from oesophageal varices. METHODS: Patients were followed from 6 to 1140 days (median 310 days). Nine patients were bleeding actively when ligation was performed. RESULTS: Eleven patients (22%) had 13 recurrent bleedings requiring blood transfusion during follow-up. Six recurrences occurred during the first month (3 from bleeding varices, 3 treatment-induced); seven recurrences occurred latter (6 from bleeding varices, 1 treatment-induced). Varices were eradicated in 33 patients (66% of all patients, 82% of patients who survived more than 30 days). Variceal eradication was achieved in 2-9 endoscopic ligation sessions (median 3). Eighteen patients died during the study; one died from bleeding. No patient developed major complications; five patients only complained of mild dysphagia for 24 to 48 hours. CONCLUSION: Endoscopic ligation is a safe and effective method to prevent recurrent bleeding from oesophageal varices.

RESUMO

A case of Rochalimaea henselae infection in an AIDS patient is reported. The R. henselae infection was revealed by febrile pancytopenia associated with liver and spleen enlargement. The diagnosis was made on the finding at histology of hepatic peliosis lesions. Within these lesions Warthin Starry staining displayed bacilli that were identified as R. henselae. This case shows that all HIV-infected patients with these symptoms might be infected with this organism.

RESUMO

BACKGROUND: Transient elastography measures liver stiffness, which correlates with the hepatic fibrosis stage and has excellent accuracy for the diagnosis of cirrhosis in patients with chronic hepatitis C. AIM: To assess prospectively the kinetics of liver stiffness in treated patients with chronic hepatitis C and compare them with the viral kinetics on treatment and with the final outcome of therapy. METHODS: 91 patients with chronic hepatitis C with significant fibrosis (>7.0kPa) at baseline were included. They received therapy with pegylated interferon-α and ribavirin. The kinetics of liver stiffness were characterized during therapy and thereafter by means of Fibroscan, and compared with the virological responses at weeks 4, 12, 24, end of treatment and 12 and 24weeks after. RESULTS: A significant liver stiffness decrease was observed during therapy, which continued after treatment only in patients who achieved a sustained virological response. In this group, the median intra-patient decrease relative to baseline at the end of follow-up was -3.4kPa, vs-1.8kPa in the patients who did not achieve an SVR. Similar dynamics were observed in cirrhotic and non-cirrhotic patients. In multivariate analysis, only the SVR was associated with long-term improvement of liver stiffness (odds ratio: 3.10; 95% confidence interval: 1.20-8.02, P=0.019). CONCLUSIONS: In patients with advanced fibrosis at the start of therapy, liver stiffness is significantly reduced during treatment, but improvement continues off treatment only in patients who achieve a sustained virological response. Liver stiffness assessment earlier than 6months after the end of therapy does not appear to be clinically meaningful.
