Comparison of simple tests for the non-invasive diagnosis of clinically silent cirrhosis in chronic hepatitis C.

BACKGROUND: Biopsy is the gold standard for assessing cirrhosis in patients with chronic hepatitis C virus infection, but it is expensive and at risk of complications. Alternative non-invasive methods have been developed but their usefulness remains uncertain. AIM: To compare the accuracy of five non-invasive scores in detecting cirrhosis. METHODS: We reviewed the charts and liver biopsies of 228 consecutive, treatment-naïve, hepatitis C virus-positive patients, 13.2% of whom with histological diagnosis of cirrhosis. The five alternative scores were age-platelet index, cirrhosis discriminant score, aspartate transaminases to platelet ratio index, Pohl's index, and aspartate transaminases/alanine transaminases ratio. RESULTS: The specificities of the scores were good (87-100%), but not so their sensitivities (17-67%). Accordingly positive likelihood ratios were generally good but negative likelihood ratios were suboptimal. Combinations of the scores independently related to cirrhosis only slightly change this diagnostic accuracy. Using double cut-offs to exclude/diagnoses cirrhosis, cirrhosis discriminant score classified 21% of patients without misdiagnoses and aspartate transaminases to platelet ratio index classified 85% of case with 9% of misdiagnoses. CONCLUSIONS: The five scores showed variable sensitivities and specificities in detecting liver cirrhosis, both individually and in combination. The use of double cut-off points may make the cirrhosis discriminant score and aspartate transaminases to platelet ratio index useful to reduce the number of patients submitted to liver biopsy.

The rational use of albumin in patients with cirrhosis and ascites. A Delphi study for the attainment of a consensus on prescribing standards.

BACKGROUND: Ascites is one of the most frequent severe complications in patients with liver cirrhosis. The treatment of this chronic disease usually requires the prolonged use of albumin, frequently continued even after patients' discharge from the hospital. AIMS: Aim of the study was to define a consensus among Italian physicians with regard to the use of albumin in patients with decompensated cirrhosis and ascites. METHODS: The study adopted the Delphi technique to conduct the consensus activities. All controversial issues related to the use of albumin were identified by the experts' board and proposed to the 68 participating hepatology centres through two subsequent questionnaires. The questionnaires, returned by the specialists involved, were collected and the answers classified to verify the elements on which a consensus was reached. RESULTS: The home use of albumin can help to improve the patient's general conditions and well-being. About 77% of the experts involved considered likely that albumin administration could shorten hospital stays or could reduce the number of hospital admissions. The results of the study, along with a socioeconomic analysis, were presented to the Italian Drug Commission, which subsequently removed the specific hypoalbuminemia level as a prerequisite for having the drug reimbursed by the National Health Service. CONCLUSIONS: For an outpatient prescription, the hypoalbuminemia limit of 2.5 g/dl or less is not sufficient, while the decision whether to administer the drug requires the evaluation of patient's overall clinical conditions as an essential criterion for the prescription of a home treatment with albumin.

Factors associated with poor health-related quality of life of patients with cirrhosis.

BACKGROUND & AIMS: Increasing interest is being given to health-related quality of life in chronic diseases. In cirrhosis, both physical functioning and mental well-being may be altered, but no study has investigated factors associated with a poor perceived health status. METHODS: We measured quality of life by Short Form-36 and Nottingham Health Profile questionnaires in 544 patients with cirrhosis. Data were compared with age- and gender-adjusted values of 2 random samples of the Italian population (more than 2000 subjects). Factors associated with poor perceived health status were identified by logistic regression. RESULTS: All domains of health-related quality of life, except pain, were altered in cirrhosis (by 9%-42%), mainly in younger patients. There were minor differences in relation to gender, whereas etiology had no effects. Severity of disease (Child-Pugh score) and, above all, muscle cramps were the factors most closely associated with poor health status perception. Self-rating of disease progression was associated with ascites and pruritus, whereas previous variceal sclerotherapy and the use of disaccharides had a protective effect. Most areas of daily life were affected by perceived health problems; this was mainly true for paid employment and sex life in men and home life and social life in women. CONCLUSIONS: Quality of life is variably impaired in cirrhosis, also in uncomplicated patients. Non-life-threatening symptoms, such as muscle cramps, are of major concern. These data are the basis for longitudinal studies measuring the effects of therapy and procedures on patient-derived health outcomes.

Bradykinin in the ascitic fluid of patients with liver cirrhosis.

Bradykinin, a nonapeptide with vasodilatory and permeabilizing activity, is generated through the cleavage of high-M(r) ('high-molecular-weight') kininogen by kallikrein, and its generation is facilitated by plasmin. In the ascitic fluid of patients with cirrhosis, there is massive cleavage of high-M(r) kininogen and activation of fibrinolysis, but bradykinin has never been measured directly. In the ascitic fluid of 24 patients with cirrhosis, we measured bradykinin-(1-9)-nonapeptide levels by RIA after liquid-phase and subsequent HPLC extraction, and those of its catabolic product bradykininin-(1-5)-pentapeptide by ELISA after liquid-phase extraction. Cleaved high-M(r) kininogen, activated factor XII and plasmin-antiplasmin complexes were measured in ascitic fluid and plasma. Plasma renin activity (PRA) was also determined. As a control, we also analysed plasma from 24 healthy subjects matched for sex and age with the patients. In the ascitic fluid from patients with cirrhosis, the median bradykinin-(1-9) concentration was 3.3 fmol/ml (range 0.2-29.0 fmol/ml), and the median bradykinin-(1-5) concentration was 210 fmol/ml (range 58-7825 fmol/ml). The levels of bradykinin-(1-5) in ascitic fluid were higher in patients with refractory ascites [median 1091 fmol/ml (range 58-7825 fmol/ml)] than in patients with responsive ascites [134 fmol/ml (72-1084 fmol/ml)] (P=0.010). Ascitic fluid levels of bradykinin-(1-9) were not related to the severity of ascites. PRA was higher in patients with refractory ascites [23.0 ng x h(-1) x ml(-1) (7.9-80.0 ng.h(-1).ml(-1))] than in patients with responsive ascites [6.9 ng x h(-1) x ml(-1) (0.9-29.4 ng x h(-1) x ml(-1))] (P=0.002). In ascitic fluid, 48% (19-68%) of high-M(r) kininogen was cleaved, and plasmin-antiplasmin complexes were more concentrated than in plasma (P=0.0001). In conclusion, in the ascitic fluid of patients with cirrhosis, both bradykinin-(1-9) and bradykinin-(1-5) are present, with cleavage of high-M(r) kininogen and activation of fibrinolysis. The highest levels of the long-lived metabolite bradykinin-(1-5) were found in the ascitic fluid of patients with refractory ascites and high PRA. Activation of the kinin system may therefore be involved in decompensating cirrhosis, but a cause-effect relationship remains to be established.

Clinical relevance of hyponatraemia for the hospital outcome of cirrhotic patients.

BACKGROUND: Hyponatraemia frequently develops in cirrhotic patients whose ability to excrete free water is impaired. The role of hyponatraemia in the prognosis of such patients is unclear. AIM: To evaluate prevalence, clinical associations and prognostic impact of hyponatraemia in cirrhotic inpatients. PATIENTS: A series of 156 cirrhotic patients consecutively admitted to our department, for a total of 191 admissions, were studied. METHODS: Serum sodium levels were determined at admission and repeated at least weekly in all patients. The clinical status and the survival of patients with hyponatraemia (< or = 130 mmol/l) were compared to those of patients with normal sodium levels. RESULTS: Hyponatraemia was found in 57 out of 191 admissions (29.8%). Bacterial infections, ascites, chronic diuretic therapy, but not gastrointestinal bleeding or renal failure, were more frequent in patients with hyponatraemia than in those with normal sodium levels. In 3 cases, none of these conditions were present and hyponatraemia was defined as "spontaneous". Hospital death rate was increased in patients with hyponatraemia (26.3% versus 8. 9%, chi2=8. 55, p=0.003). By multivariate analysis, the only parameters independently associated with survival were high serum bilirubin (p=0.006) and high serum urea levels (p=0.019). Twenty-five patients developed severe hyponatraemia (<125 mmol/l) during hospital stay. This event was associated with a concomitant bacterial infection in 21 cases. The mortality rate of these patients was very high (48%). CONCLUSIONS: Hyponatraemia is frequent in cirrhotic inpatients. It is seldom a spontaneous event but rather occurs in association with ascites, chronic use of diuretics or bacterial infections. It is a negative prognostic factor associated with increased short-term mortality.

Cost analysis for the prevention of variceal rebleeding: a comparison between transjugular intrahepatic portosystemic shunt and endoscopic sclerotherapy in a selected group of Italian cirrhotic patients.

The aim of the present study was to compare the cumulative cost of the first 18-month period in a selected group of Italian cirrhotic patients treated with transjugular intrahepatic portosystemic shunt (TIPS) versus endoscopic sclerotherapy (ES) to prevent variceal rebleeding. Thirty-eight patients enrolled in a controlled trial were considered (18 TIPS and 20 sclerotherapy). The number of days spent in the hospital for the initial treatment and during the follow-up period were defined as the costs of hospitalization. ES sessions, TIPS procedures, angioplasty or addition of a second stent to maintain the shunt patency, were defined as the costs of therapeutic procedures. The two groups were comparable for age, sex, and Child-Pugh score. During the observation period 4 patients died in the TIPS group, and 2 died and 1 was transplanted in the sclerotherapy group. The rebleeding rate was significantly higher in the sclerotherapy group. Despite this, the number of days spent in the hospital was similar in the two groups. This was because of a higher number of hospital admissions for the treatment of hepatic encephalopathy and shunt insufficiency in the TIPS group. The therapeutic procedures were more expensive for TIPS. Consequently, the cumulative cost was higher for patients treated with TIPS than for those treated with sclerotherapy. The extra cost was because of the initial higher cost of the procedure and the difference was still maintained at the end of the 18-month follow-up. When the cumulative costs were expressed per month free of rebleeding, the disadvantage of TIPS disappeared. In conclusion, a program of prevention of variceal rebleeding with TIPS, despite the longer interval free of rebleeding, is not a cost-saving strategy in comparison with sclerotherapy.

Changing clinical practice through research: the case of delirium.

Promoting application of study findings to the clinical setting is a constant challenge for nurse researchers. This project used change theory to include staff RNs in a research study on delirium and to use relevant findings. The research hypothesis was: Staff nurses who use a standardized protocol will have improved ability to identify delirium in elderly hospital patients. Staff nurses on the intervention unit used this protocol to screen for delirium on all consenting inpatients 75 years of age and over, and control unit nurses continued using their standard assessment practices. Intervention unit nurses demonstrated an improved ability to identify the presence and absence of delirium, and voluntarily requested to continue using the protocol after the study was terminated. Use of a theoretical model to include nurses in the study promoted the successful conduct of the research and subsequent use of findings.

Parallel reduction of plasma levels of high and low molecular weight kininogen in patients with cirrhosis.

Little is known about the regulation of high-molecular-weight-kininogen (HK) and low-molecular-weight-kininogen (LK) or the relationship of each to the degree of liver function impairment in patients with cirrhosis. In this study, we evaluated HK and LK quantitatively by a recently described particle concentration fluorescence immunoassay (PCFIA) and qualitatively by SDS PAGE and immunoblotting analyses in plasma from 33 patients with cirrhosis presenting various degrees of impairment of liver function. Thirty-three healthy subjects served as normal controls. Patients with cirrhosis had significantly lower plasma levels of HK (median 49 microg/ml [range 22-99 microg/ml]) and LK (58 microg/ml [15-100 microg/ml]) than normal subjects (HK 83 microg/ml [65-115 microg/ml]; LK 80 microg/ml [45-120 microg/ml]) (p<0.0001). The plasma concentrations of HK and LK were directly related to plasma levels of cholinesterase (P<0.0001) and albumin (P<0.0001 and P<0.001) and inversely to the Child-Pugh score (P<0.0001) and to prothrombin time ratio (P<0.0001) (reflecting the clinical and laboratory abnormalities in liver disease). Similar to normal individuals, in patients with cirrhosis, plasma HK and LK levels paralleled one another, suggesting that a coordinate regulation of those proteins persists in liver disease. SDS PAGE and immunoblotting analyses of kininogens in cirrhotic plasma showed a pattern similar to that observed in normal controls for LK (a single band at 66 kDa) with some lower molecular weight forms noted in cirrhotic plasma. A slight increase of cleavage of HK (a major band at 130 kDa and a faint but increased band at 107 kDa) was evident. The increased cleavage of HK was confirmed by the lower cleaved kininogen index (CKI), as compared to normal controls. These data suggest a defect in hepatic synthesis as well as increased destructive cleavage of both kininogens in plasma from patients with cirrhosis. The decrease of important regulatory proteins like kininogens may contribute to the imbalance in coagulation and fibrinolytic systems, which frequently occurs in cirrhotic patients.

Clinical practice guidelines for the management of cirrhotic patients with ascites. Committee on Ascites of the Italian Association for the Study of the Liver.

An ad hoc Committee appointed by the Italian Association for the Study of the Liver prepared these Clinical Practice Guidelines for the Management of Cirrhotic Patients with Ascites. The initial evaluation of a patient with ascites should include a history, physical evaluation, paracentesis with ascitic fluid analysis, abdominal ultrasonography and biochemistry to assess the severity of liver disease and renal functionality. To improve the efficiency of the choice between the different opportunities available in the treatment of ascites, patients can be classified into two subgroups: patients with uncomplicated ascites and patients with complicated ascites, including refractory ascites, bacterial peritonitis, hyponatraemia and renal failure. Based upon evidence emerging from controlled clinical trials or case-control studies, satisfactory treatment for uncomplicated ascites is represented by paracentesis, sodium-restricted diet and diuretics, whereas the treatment of patients with complicated ascites requires other specific approaches. As the prognosis for most patients with ascites is poor, the last part of the paper offers simple criteria in the selection of patients candidates for liver transplantation. The aim of these guidelines is to reduce inappropriate practice and to improve efficiency in the management of patients with ascites. The Committee holds that a periodic update will be necessary to conform to future scientific developments.

Transjugular intrahepatic portosystemic shunt versus endoscopic sclerotherapy for the prevention of variceal bleeding in cirrhosis: a randomized multicenter trial. Gruppo Italiano Studio TIPS (G.I.S.T.).

Transjugular intrahepatic portosystemic shunt (TIPS), a new technique for the treatment of portal hypertension, has been successful in preliminary studies to treat acute variceal hemorrhage and to prevent variceal rebleeding. The purpose of this multicenter, randomized controlled trial is to compare the efficacy of TIPS with that of endoscopic sclerotherapy in the prevention of variceal rebleeding in cirrhosis. Eighty-one cirrhotic patients, with endoscopically proven variceal bleeding, were randomized to either TIPS (38 patients) or endoscopic sclerotherapy (43 patients). Randomization was stratified according to the following: if bleeding occurred < 1 week (stratum I); if bleeding occurred 1 to 6 weeks (stratum II); and if bleeding occurred 6 weeks to 6 months (stratum III) before enrollment. Follow-up included clinical, biochemical, Doppler Ultrasound, and endoscopic examinations every 6 months. During a mean follow-up of 17.7 months, 51% of the patients treated with sclerotherapy and 24% of those treated with TIPS rebled (P = .011). Mortality was 19% in sclerotherapy patients and 24% in TIPS patients (P = .50). Hepatic encephalopathy (HE) developed in 26% and 55%, respectively (P = .006). A separate analysis of the three strata showed that TIPS was significantly more effective than sclerotherapy (P = .026) in preventing rebleeding only in stratum I patients. TIPS is significantly better than sclerotherapy in preventing rebleeding only when it is performed shortly after a variceal bleed; however, TIPS does not improve survival and is associated with a significantly higher incidence of HE. The overall performance of TIPS does not seem to justify the adoption of this technique as a first-choice treatment to prevent rebleeding from esophageal varices in cirrhotic patients.

Reduction of renal cortical blood flow assessed by Doppler in cirrhotic patients with refractory ascites.

The usefulness in cirrhotic patients of hemodynamic measurements by Doppler ultrasonography (US) is still not defined. We investigated the relationships between Doppler measurements and the severity of ascites. Portal blood flow velocity and volume, and hepatic and renal arterial resistance indexes (RI) were measured in 57 cirrhotic patients (19 without ascites, 28 with responsive ascites, and 10 with refractory ascites) and 15 healthy controls. The renal arterial RI were obtained for the main renal artery, interlobar vessels, and cortical vessels. Cirrhotic patients had decreased portal blood flow and an increased congestion index (CI). Only the CI was correlated to the severity of ascites, showing that it is also a reliable measure of the severity of portal hypertension in patients with ascites. The hepatic and renal artery RI were increased in cirrhotic patients, and the two values were correlated (r = .68; P = .00001). The RI of renal interlobar and cortical vessels were higher in patients with refractory ascites than in patients without ascites (P < .02 and P < .009), and correlated with sodium excretion rate (r = -.45; P < .003), the renin-aldosterone system, and creatinine clearance (r = -.62; P < .0002). The RI decreased from the hilum of the kidney to the outer parenchyma in healthy subjects and patients with responsive ascites, but this difference disappeared in patients with refractory ascites. This indicates that the degree of renal vasoconstriction varies in different areas according to the severity of the ascites. Cortical vessels are involved mainly in patients with refractory ascites, suggesting that the intrarenal blood flow distribution in cirrhosis tends to preserve the cortical area and that severe cortical ischemia is a feature of refractory ascites.

Pattern of plasma cyclic nucleotides and related hormones in liver cirrhosis and hepatocellular carcinoma.

To evaluate the pattern of plasma cyclic adenosine 3',5'-monophosphate, cyclic guanosine 3',5'-monophosphate, atrial natriuretic factor and glucagon levels in different stages of chronic liver diseases, we measured these variables in 20 normal subjects, 25 patients with genetic hemochromatosis, associated with liver cirrhosis in 19 cases and not in six, eight patients with compensated and 15 with decompensated alcoholic or posthepatitic cirrhosis, and 12 with hepatocellular carcinoma. All variables were within the normal range in non-cirrhotic hemochromatotic patients. Cyclic adenosine 3',5'-monophosphate levels were within the normal range (9.5-15.7 nmol/l) in hemochromatotic cirrhotics and elevated in other patients. Cyclic guanosine 3',5'-monophosphate, atrial natriuretic factor and glucagon were above the normal ranges (1.92-5.91 nmol/l, 8.8-62.7 ng/l, and 39-165 ng/l, respectively) in most patients with cirrhosis both with and without hemochromatosis and in most individuals with hepatocellular carcinoma. Cyclic guanosine 3',5'-monophosphate correlated with atrial natriuretic factor in the former groups but not in the latter. These findings indicate that glucagon and atrial natriuretic factor hypersecretion is an early event in cirrhosis, regardless of its etiology. In hepatocellular carcinoma, the underlying cirrhosis may account for most hormonal and metabolic changes although cyclic guanosine 3',5'-monophosphate increases could also be due to the neoplastic process per se.

Lack of renal effects of fish oil administration in patients with advanced cirrhosis and impaired glomerular filtration.

The treatment of renal failure in cirrhotic patients with ascites remains unsatisfactory. Recent studies have shown that the dietary supplementation with fish oil improves the renal function of normal subjects, as well as that of patients with renal failure of different etiologies. We have investigated the renal effects of a daily supplementation for 1 month of 12 g fish oil (27% C20:5 n-3 eicosapentanoic acid [EPA], and 23% C22:6 n-3 docosahexanoic acid [DHA]) in a prospective study of cirrhotic patients with ascites, nine with normal renal function (group 1) and eight with renal failure (glomerular filtration rate [GFR] < 60 mL/min, group 2). Compliance with the dietary regimen was confirmed by fatty acid chromatography that showed increased plasma concentration of EPA (from 1.5 +/- 0.7% to 3.7 +/- 0.8%, P = .024, in group 1; and from 0.53 +/- 0.3% to 2.9 +/- 0.8%, P = .03, in group 2) and of DHA (from 2.1 +/- 0.4% to 3.4 +/- 0.3%, P = .008, in group 1; and from 1.45 +/- 0.5% to 3.8 +/- 0.4%, P = .05, in group 2). At the end of the study, in patients from group 1, the glomerular filtration rate increased by 19% (from 94 +/- 8 to 113 +/- 13 mL/min, P = .039), and the urine flow increased by 39% (from 0.85 +/- 0.14 to 1.12 +/- 0.2 mL/min, P = .039), while no changes occurred in the renal function of patients from group 2. No changes were observed in the urinary excretion of prostaglandin (PG) E2 or of 6-keto prostaglandin-1-alpha (6-K-PGF1-alpha) nor in plasma renin activity (PRA) or the plasma concentration of aldosterone (PA) or antidiuretic hormone (ADH) in both groups. As far as undesirable effects of fish oils were considered, the mean arterial pressure (MAP) decreased in both groups (group 1: from 88.6 +/- 2 to 85.3 +/- 2 mm Hg, P = .015; group 2: from 88.2 +/- 3 to 82.8 +/- 3 mm Hg, P = .05), and bleeding time displayed a significant increase when patients were considered collectively (from 744 +/- 89 to 872 +/- 106 seconds, P = .0068). In conclusion, the administration of fish oil for 1 month was unable to improve renal function in cirrhotic patients with ascites and renal failure. The occurrence of undesirable effects, such as the reduction of arterial pressure and the prolongation of bleeding time, argues against the use of fish oils in these patients.

Octreotide long-term treatment in patients with portal hypertension: persistent inhibition of postprandial glucagon response without major changes in renal function.

BACKGROUND/AIMS: Octreotide acutely decreases splanchnic blood flow and postprandial portal pressure in patients with portal hypertension. Inhibition of glucagon release parallels the hemodynamic changes. We studied the hormonal and renal effects of long-term treatment with octreotide (100 microg s.c., t.i.d., immediately before meals, for 2 weeks) in 12 patients with cirrhosis and portal hypertension. METHODS: Postprandial blood levels of glucagon, insulin and glucose, and renal function tests were monitored in a study where patients acted as their own controls. Eleven patients completed the study, octreotide being discontinued in one patient who developed jaundice after 6 days of therapy. RESULTS: Long-term treatment did not cause any change in fasting hormonal levels measured 12 h after the last injection of octreotide. However, pre-prandial injection of octreotide induced a marked fall in blood glucagon (163+/-49 pg/ml, after 20 min, vs. 254+/-71 pg/ml, basal; p<0.01), thus preventing the postprandial response occurring without treatment (322+/-102 pg/ml, 30 min-peak, vs. 249+/-77 pg/ml, basal; p<0.03). Inhibition of postprandial glucagon was maintained after 2 weeks of therapy (159+/-33 pg/ml, after 20 min, vs. 237+/-54 pg/ml, basal; p<0.01). Octreotide abolished the insulin postprandial response with no major change in glycemic control. Treatment had no long-term effect on renal plasma flow (effective renal plasma flow: 596+/-79 ml/min, baseline, vs. 609+/-71 ml/min, at 2 weeks; p>0.5), glomerular filtration rate (glomerular filtration rate: 99+/-11 vs. 99+/-12 ml/min; p>0.5), blood urea and creatinine, whereas it induced a mild decrease in plasma electrolyte levels (p<0.02). CONCLUSIONS: Long-term octreotide treatment persistently suppresses the postprandial glucagon response of patients with portal hypertension without causing deterioration in their renal function.

Prevalence and incidence of cholelithiasis in patients with liver cirrhosis.

AIMS: To evaluate the prevalence, the incidence and the history of cholelithiasis in liver cirrhosis. PATIENTS AND METHODS: A series of 233 consecutive cirrhotic patients (193 Child A, 35 Child B and 5 Child C) were assessed for cholelithiasis by ultrasonography. Of these, 201 (those who had never had cholecystectomy) were followed-up with repeated ultrasonographies. RESULTS: The prevalence of cholelithiasis was 38% (22% gallstones and 16% previous cholecystectomies). No relationships with the usual risk factors for cholesterol gallstones, such as age, sex, body mass index, serum glucose or triglycerides, were found. On the contrary, close correlations were observed with serum albumin, bilirubin, prothrombin time and Pugh score. By multivariate analysis, only serum bilirubin was independently correlated with cholelithiasis. Histories of biliary pain were more frequent in patients with previous cholecystectomy (62% cases) than in those with gallstones (21%) and those without cholelithiasis (7%). On the contrary, complaints of dyspepsia were similar in the three groups of patients. During a mean follow-up of 34.4 +/- 0.9 months, there was a 4.9% annual rate of development of new stones in 127 patients without cholelithiasis at the first investigation. This rate is markedly higher than that reported for normal subjects in a previous survey carried out in a similar geographic area. During a mean follow-up of 31.8 +/- 1.2 months, symptoms or complications were seen in 2 out of 45 patients with initial gallstones (4.4%). The annual rate of complications was estimated to be less than 2%. CONCLUSIONS: Cholelithiasis is frequently associated with cirrhosis and the risk of developing new stones remains high during the natural history of the disease.

Factors affecting insufficiency in activity daily living in the elderly.

BACKGROUND: In a "case-control" study we investigated the correlations among twenty-four clinical signs of "functional impairment" and probability of "activity daily living insufficiency". METHODS: The study involved 788 randomised inpatients, aged 65 years and over, of nineteen long-stay hospitals of an Italian region (Lazio, Rome). We measured self care autonomy, mobility and continence, on a modified Barthel's scale; the score on Barthel's scale, Barthel Index (BI), was correlated to twenty-four signs of "functional impairment" (explicative variables). Of these variables entered in stepwise regression only "cognitive impairment" (coef. B-22), "paralysis" (coef. B-21), "body weight reduction over 10 kg vs ideal weight" (coef. B-12), "joint deformation" (coef. B-7) and "visual impairment" (coef. B-5). Insufficiency in daily living is defined by BI < 100. The presence of these five clinical signs leads to the likelihood of "activity daily living insufficiency" to 0.996. The trend of cognitive impairment to rise with age could be responsible for the inverse regression between age and BI. RESULTS: There was no significant correlation between BI and sex. Hearing impairment, serum creatinine level > or = 4 mg/dl, bronchospasm, obstructive and restrictive ventilation disorders, precordial pain on stress or spontaneous and dyspnea are not significantly correlated to the Barthel Index Score and to the likelihood of insufficiency in daily living activity.

Efficacy of oral ciprofloxacin as selective intestinal decontaminant in cirrhosis.

BACKGROUND: Selective intestinal decontamination has been proposed to prevent bacterial infection in cirrhosis. AIMS: To evaluate the efficacy of ciprofloxacin as selective intestinal decontaminant. PATIENTS AND METHODS: Quantitative microbiological studies on serial faeces were carried out in 15 cirrhotic patients. Ciprofloxacin was given orally at the starting dose of 250 mg every 12 hours for 7 days followed by a single dose of 250 mg/day from day 7 to day 14 and 125 mg/day for the next 3 weeks. Total stool samples were examined in basal conditions and on days 7, 14, 21, 28 and 35 of treatment and 3 and 7 days after treatment withdrawal. RESULTS: Gram-negative flora was completely eliminated in all patients by ciprofloxacin given at doses of 500 and 250 mg/day. When the drug was tapered to 125 mg/day, Escherichia coli reappeared in stools of 7 patients (antibiotic-resistant in one patient) and Klebsiella oxytoca in two patients (antibiotic-resistant in one patient). Faecal concentration of Group D Streptococcus was significantly increased at the end of therapy (basal mean 7.7 +/- 1.2 log CFU vs post treatment mean 9.6 +/- 0.5 log CFU, p < 0.05) while the faecal concentration of anaerobic flora and Candida albicans showed no change. CONCLUSIONS: Results of this study demonstrate the efficacy of oral ciprofloxacin as a selective intestinal decontaminant and ciprofloxacin 250 mg/day is the recommended dose for maintaining Selective Intestinal Decontamination. However, the risks of inducing antibiotic resistance in Gram-negative flora and promoting overgrowth of Gram-positive flora must be carefully considered in all patients chronically treated with oral quinolones.

Randomized trial comparing albumin, dextran 70, and polygeline in cirrhotic patients with ascites treated by paracentesis.

BACKGROUND & AIMS: Paracentesis associated with plasma expanders is widely used for the treatment of ascites in cirrhosis. This study investigated the clinical importance of paracentesis-induced-circulatory dysfunction and compared the efficacy of albumin, dextran 70, and polygeline in preventing this complication. METHODS: A total of 289 cirrhotic patients with ascites were randomized to treatment by total paracentesis plus intravenous albumin (97 patients), dextran 70 (93 patients), or polygeline (99 patients). Postparacentesis circulatory dysfunction was defined as an increase in plasma renin activity on the sixth day after paracentesis of more than 50% of the pretreatment value to a level > 4 ng.mL-1.h-1. RESULTS: Postparacentesis circulatory dysfunction occurred more frequently in patients treated with dextran 70 (34.4%; P = 0.018) or polygeline (37.8%; P = 0.004) than in those receiving albumin (18.5%). The plasma expander used and the volume of ascites removed were independent predictors of this complication. Postparacentesis circulatory dysfunction persisted during follow-up and was associated with a shorter time to first readmission (1.3 +/- 0.5 vs. 3.5 +/- 0.8 months, median +/- SEM; P = 0.03) and shorter survival (9.3 +/- 4.2 vs. 16.9 +/- 4.3 months; P = 0.01). Creatinine and sodium levels in serum, and Child-Pugh score at inclusion, and postparacentesis circulatory dysfunction were independent predictors of survival. CONCLUSIONS: Postparacentesis circulatory dysfunction is not spontaneously reversible and is associated with a shorter time to first readmission and shorter survival. Albumin is the best plasma expander to prevent this complication.
