RESUMEN
Treating chronic hepatitis C with pegylated interferon alpha may induce or exacerbate psychiatric illness including depression, mania and aggressive behaviour. There is limited data regarding treatment in the context of chronic schizophrenia. We sought to establish the safety and efficacy of treating patients with schizophrenia. Patient and treatment data, prospectively collected on the Scottish hepatitis C database, were analysed according to the presence or absence of a diagnosis of schizophrenia. Time from referral to treatment, and the proportion of patients commencing treatment in each group, was calculated. Outcomes including sustained viral response rates, reasons for treatment termination and adverse events were compared. Of 5497 patients, 64 (1.2%) had a diagnosis of schizophrenia. Patients with schizophrenia (PWS) were as likely to receive treatment as those without [28/61(46%) vs 1639/4415 (37%) P = 0.19]. Sustained viral response (SVR) rates were higher in PWS [21/25 (84%) vs 788/1453 (54%) P < 0.01]. SVR rates by genotype were similar [4/8 (50%) vs 239/684 (35%) Genotype 1 (P = 0.56), 17/17 (100%) vs 599/742 (81%) non-Genotype 1 (P = 0.09)]. Adverse events leading to cessation of treatment were comparable [2/25(8%) vs 189/1453 (13%) P: 0.66]. Patients with schizophrenia are good candidates for hepatitis C treatment, with equivalent SVR and treatment discontinuation rates to patients without schizophrenia.

BACKGROUND AND AIMS: Whilst hepatitis B (HBV) is historically uncommon in Scotland, anecdotal experience suggests an increasing prevalence of chronic infection. We sought to establish whether the incidence of chronic HBV is increasing in Greater Glasgow, and whether patients are assessed in secondary care. METHODS: The regional virus centre database identified HBV surface antigen (HBsAg) positive samples. For adult patients tested in Glasgow between 1993-2007 the first positive test was identified and classified as acute or chronic infection serologically. Clinic referral and attendance data was then obtained. RESULTS: 1,672 patients tested HBsAg positive; 1051 with chronic infection, 421 acute and 200 indeterminate. New diagnoses of HBV remained stable over time, however falling numbers of acute cases were mirrored by a rise in chronic cases from 40 to 119 per annum between 2000 and 2007. Of 193 patients diagnosed in 2006 and 2007, 51% were not seen in secondary care due to non referral (43%) or non attendance (8%). CONCLUSION: Chronic HBV trebled in Glasgow between 2000 and 2007. Most patients were not assessed in secondary care. Improved levels of clinic referral and attendance are required to ensure best care for HBV patients in Glasgow.

Alcoholic hepatitis (AH) is an acute deterioration in liver function seen in the context of prolonged excessive alcohol consumption and is characterised by the rapid onset of jaundice. The diagnosis of AH has been controversial for many years: it is now accepted that there are clear clinical criteria which can be used to diagnose AH without the need for a liver biopsy. Corticosteroids remain the only treatment proven to be effective in reducing short-term mortality in severe AH; abstinence from alcohol is the most important factor in determining long-term survival. It is recommended a trial of corticosteroid therapy is considered only in those patients with high baseline 'static' scores (Glasgow Alcoholic Hepatitis score and model for end-stage liver disease). Response to corticosteroid therapy should be assessed using a 'dynamic' score such as the Lille score at day 7, with corticosteroids continuing only in patients with a favourable score. Infection and acute kidney injury are associated with poorer outcomes in AH. Early screening for and treatment of infection is recommended with antibiotic therapy overlapping with any subsequent corticosteroid treatment. A biomarker which predicts benefit from corticosteroids at baseline would avoid a trial of therapy to determine response. More efficacious therapeutic options for AH patients are required with N-acetylcysteine, granulocyte colony stimulating factor, faecal microbiota transplantation and routine antibiotics showing promise, but adequate controlled trials are needed to confirm efficacy. Liver transplant has an emerging role for some patients with severe AH not responding to corticosteroids and is likely to become more acceptable with improved methods of patient selection.
RESUMEN
INTRODUCTION: There is no consensus on the pharmacological treatment of alcoholic hepatitis. The Glasgow alcoholic hepatitis score (GAHS) has been shown to be more accurate than the modified Maddrey's discriminant function (mDF) in the prediction of outcome from alcoholic hepatitis. This study aimed to determine whether the GAHS was able to identify those patients who would benefit from corticosteroids. METHODS: 225 patients with an mDF greater than or equal to 32 from five hospital centres in the United Kingdom were reviewed. Patient survival relative to the GAHS and the use of corticosteroids was recorded. RESULTS: 144 patients with an mDF greater than or equal to 32 (64%) also had a GAHS greater than or equal to 9. There was no difference in survival between untreated or corticosteroid-treated patients for those with a GAHS less than 9. For patients with a GAHS greater than or equal to 9 the 28-day survival for untreated and corticosteroid-treated patients was 52% and 78% (p = 0.002), and 84-day survival was 38% and 59% (p = 0.02), respectively. CONCLUSIONS: Among patients with an mDF greater than or equal to 32, there was no appreciable benefit from treatment with corticosteroids in patients with a GAHS less than 9. Patients with a GAHS greater than or equal to 9 have an extremely poor prognosis if they are not treated with corticosteroids, or if such treatment is contraindicated.

BACKGROUND: Alcoholic hepatitis is a severe acute manifestation of alcoholic liver disease with a high mortality. Management of patients with this condition has been a matter of controversy for many years; however, recent clinical studies have sought to improve the clinical approach to these patients. AIM: To use these recent studies in order to guide clinical management. METHODS: A MeSH search of Medline was performed to specifically identify recent studies which influenced clinical diagnosis, assessment and management of alcoholic hepatitis. RESULTS: Fulfilment of clear clinical criteria including a minimum threshold of bilirubin, defined periods of jaundice and alcohol ingestion negates the need for liver biopsy in most patients. Corticosteroids improve short-term mortality only (28 day) with other factors such as abstinence likely to be significant in long-term outcome. Pentoxifylline is not an effective treatment. The Glasgow Alcoholic Hepatitis Score (GAHS) score can identify those patients likely to benefit from corticosteroids, but scores that include the evolution of bilirubin over 1 week of such treatment (such as the Lille Score) define "response". Underlying infection may contribute towards corticosteroid nonresponse and needs to be actively sought out and treated. Liver transplant remains controversial; however, it has been shown to be feasible in alcoholic hepatitis. CONCLUSIONS: Recent studies have helped to define patients who may benefit from corticosteroid treatment. However, there remains a need for more accurate scores of prognosis and treatment response, and a clear need for alternative treatments for those patients not responding to corticosteroid therapy.

BACKGROUND: Over the last 25 years there has been a large increase in alcohol related deaths in Scotland. Medical patients who misuse alcohol may have overt alcohol related disease, but may also present with other unrelated illness. AIM: We examined alcohol misuse amongst acute medical admissions to compare this with other similar studies at the same hospital since 1974. PATIENTS AND METHODS: 850 consecutive admissions to the medical receiving unit of Victoria Infirmary were assessed. They were assessed using the modified Michigan Alcohol Screening Test (MAST) and also by a medical consultant. 414 patients also had their blood ethanol levels measured on admission. RESULTS: 18.6% admissions had a MAST greater than 5 and were considered to misuse alcohol (24.8% male and 12.2% female; p < 0.0001). Patients from socio-economic group V and patients presenting with gastro-intestinal haemorrhage or self-poisoning were more likely to misuse alcohol. The sensitivity and specificity of consultant opinion regarding alcohol misuse were 0.55 and 0.97 compared with the MAST. There was an increase in the alcohol misuse amongst women admitted (12.2%) compared to 1977 (5.5%; p = 0.0026) and 1981/2 (6.3%; p = 0.004). CONCLUSION: Alcohol misuse is common amongst acute medical admissions. Since 1979, there has been a particular increase in female medical admissions who misuse alcohol. Medical opinion regarding alcohol misuse lacks sensitivity in identifying at risk individuals compared with a validated.

Renal dysfunction in cirrhosis describes a spectrum of abnormalities which lead to the clinical manifestations of ascites, peripheral oedema and hepato-renal failure. This article reviews the processes underlying this dysfunction with particular regard to the disturbance in the renal circulation. Renal haemodynamic changes occur early in cirrhosis prior to the development of ascites. However, as the liver disease progresses these changes become more profound and lead ultimately to severe cortical hypoperfusion. Renal blood flow and glomerular filtration rate do not appear to correlate well with the presence of ascites, and a separate defect in tubular sodium handling is likely to be present. The development of portal hypertension is a possible trigger of increased renal vascular resistance, whereas a deterioration in liver function may relate to the impaired tubular handling of sodium. The peripheral vasodilatation hypothesis seeks to relate these renal changes to the activation of vasopressor systems after the development of arteriolar vasodilatation. Correlations between systemic vascular resistance and renal blood flow have been difficult to establish. A variety of substances may mediate the renal circulatory changes. The likelihood is that the increase in systemic vasoconstrictors is compensatory, and that it is the locally active vasoactive substances, particularly those derived from the endothelium, which play a major role in the development of renal vasoconstriction. The management of ascites is fraught with complications, and the treatment of hepato-renal syndrome inadequate. Liver transplantation is currently the only therapy which gives any hope of long-term response and survival. Methods of improving the renal circulation by mechanically lowering portal pressure or by antagonizing locally active renal vasoconstrictors may be beneficial.

BACKGROUND: The aim of this study was to clarify the actions of propranolol and isosorbide-5-mononitrate upon the portal circulation. METHODS: Portal haemodynamics were assessed in 16 patients with transjugular intrahepatic portosystemic stent shunts. A reverse thermodilution catheter was positioned in the portal vein, and portal vein pressure and portal vein flow were measured directly. The effects of propranolol 80 mg and isosorbide-5-mononitrate 20 mg over 1 h were determined independently. RESULTS: This demonstrated that propranolol reduced both portal pressure gradient (7.7 +/- 2.3 to 5.5 +/- 2.1 mmHg, P < 0.01) and portal vein flow (925 +/- 123 to 597 +/- 99 mL/min, P = 0.01) significantly, implying a reduction in splanchnic inflow as its main effect. In contrast, isosorbide-5-mononitrate tended to increase portal vein flow (814 +/- 186 to 911 +/- 211 mL/min; P = 0.06) whilst reducing portal pressure significantly (108 +/- 12 to 92 +/- 10 mmHg P = 0.014). This suggests a fall in intrahepatic resistance and provides no evidence for baroreceptor-mediated reflex splanchnic vasoconstriction. CONCLUSIONS: These drugs act upon different variables contributing to portal hypertension and so they may have a powerful synergistic effect in combination. Direct measurement of portal vein flow is a valuable method for assessing the pharmacological modulation of portal venous inflow.

BACKGROUND: Transjugular intrahepatic portosystemic stent shunts (TIPSS) have been used successfully to reduce portal pressure in the context of variceal haemorrhage. Recent interest has focused on the possible use of TIPSS to manage refractory ascites. AIM: To study the effect of TIPSS insertion in 18 patients with refractory ascites. RESULTS: Response rates were 33.3%, 50%, 33.3% and 26.7% at 1 week, 4 weeks, 3 months and 6 months, respectively. Overall mortality was 50% with a new or worsening encephalopathy rate also of 50%. Patients with lower serum bilirubin and serum creatinine prior to TIPSS insertion had greater response at 1 and 4 weeks, respectively. There was no improvement in either liver or renal function after TIPSS insertion by standard laboratory tests, although serum sodium increased in the responders after 1 month. CONCLUSION: TIPSS improves refractory ascites in only a minority of patients, and is associated with high encephalopathy and mortality rates.

BACKGROUND: It has been suggested that adenosine is involved in the renal haemodynamic and tubular abnormalities observed in cirrhosis. Low-dose theophylline is an adenosine antagonist and recent studies have shown that this drug can improve renal blood flow and sodium excretion in cirrhotic patients. METHODS: Fifteen patients with newly diagnosed cirrhotic ascites were randomized to receive either 100 mg spironolactone daily for 7 days or 250 mg theophylline on days 1, 2, 4 and 6. Baseline clinical and urinary and serum biochemical data were collected and compared following therapy. RESULTS: After 7 days of spironolactone there were increases in urinary sodium excretion (43.5 +/- 15.6 vs. 106.8 +/- 34.7 mmol/day; P < 0.05) and urine volume (769.1 +/- 206.5 vs. 1541.6 +/- 342.6 mL/day; P < 0.05). No changes in the patients' weight, creatinine clearance or serum electrolytes were observed. No change was detected in any of these parameters following theophylline therapy. CONCLUSION: Adenosine antagonism in the form of low-dose theophylline is less efficacious than spironolactone in the management of cirrhotic ascites.

The relationship between the various haemodynamic abnormalities observed in cirrhosis and their prognostic value remains unclear. We report haemodynamic measurements on 96 patients with alcoholic cirrhosis (mean Childs-Pugh Score, CPS, 9.0 +/- 0.2, mean age 55.6 +/- 1.0 years) and assess their value in predicting variceal bleeding and death during a mean follow-up of 19.3 +/- 1.5 months. Baseline CPS correlated with hepatic venous pressure gradient (HVPG) (p = 0.001), azygos blood flow (p < 0.05), cardiac index (p < 0.05), and inversely with mean arterial pressure (p < 0.01) and systemic vascular resistance index (p < 0.05). Renal blood flow was not related to any haemodynamic parameter or CPS. Thirty-eight patients died during follow-up, and 16 had a variceal bleed. Death (p = 0.001) and variceal bleeding (p < 0.05) were more likely in patients with HVPG > 16 mmHg than in those with HVPG < 16 mmHg, and variceal bleeding was more likely in patients with HVPG > 12 mmHg (vs. HVPG < 12 mmHg, p < 0.05). HVPG also predicted death and variceal haemorrhage on univariate and multivariate analyses. No other haemodynamic parameter predicted death or bleeding. In alcoholic cirrhosis, severity of liver disease is related to HVPG, collateral blood flow and degree of systemic circulatory abnormalities. HVPG is a useful predictor of survival and variceal bleeding in these patients.

OBJECTIVE: Portal haemodynamics vary in response to eating and other stimuli, but any increase in portal venous pressure (PVP) in cirrhotic patients may be a risk factor for variceal bleeding. We directly assessed post-prandial splanchnic haemodynamics in cirrhotic patients with a transjugular intrahepatic portosystemic stent-shunt (TIPSS) in situ. METHODS: A thermodilution catheter was inserted via the patent TIPSS into the portal vein in 12 cirrhotic patients. PVP,portal venous flow (PVF) (thermodilution method), portal vascular resistance (PVR), porto-atrial pressure gradient (PPG), heart rate, mean arterial pressure (MAP) and right atrial pressure (RAP) were measured. A 505 kcal meal was given and all haemodynamic measurements were repeated at 15 min intervals for 60 min. RESULTS: Following the meal, there was a significant rise in PVP from 11.2 +/- 1.5 to 14.0 +/- 1.9 mmHg at 15 min, and 14.0 +/- 1.8 mmHg at 30 min (P < 0.001); in PPG from 9.5 +/- 1.4 to 12.7 +/- 2.2 mmHg at 15 min and 12.7 +/- 2.1 mmHg at 30 min (P < 0.005); and in PVF from 1110.2 +/- 141.1 to 1543.2 +/- 227.6 ml/min at 30 min (P < 0.01). PVR feil from 0.08 +/- 0.01 to 0.05 +/- 0.01 RU at 30 min (P < 0.05). Heart rate increased from 77 +/- 4.1 to 80.5 +/- 5.4 bpm at 15 min (p < 0.05), but MAP and RAP remained unchanged. CONCLUSION: In cirrhotic patients with TIPSS, significant changes in portal haemodynamics occur at 15-30 min following a meal, with minimal effect on systemic haemodynamics. This model offers a new technique to directly assess the causes for and possible treatments of post-prandial splanchnic hyperaemia in cirrhosis.

BACKGROUND: Patients with alcoholic liver disease (ALD) presenting with jaundice have advanced chronic ALD and/or acute alcoholic hepatitis. Their prognosis is poor. These patients may be managed by General Medical physicians (GM) or by Gastroenterologists (GE). AIM: This study aimed to retrospectively assess the differences in management and outcome of jaundiced ALD between GM and GE. PATIENTS AND METHODS: Patients with a serum bilirubin greater than 80 mmol/l on admission and a history of alcohol excess until within three weeks of admission were identified retrospectively. In particular the use of corticosteroids (CS), nutritional support (N) and the use of broad-spectrum antibiotics (A/b) were noted. RESULTS: 97 patients were identified, 62 managed by GE. Differences were apparent between GE and GM managed patients with respect to CS (p = 0.017), N (p < 0.001) and A/b (p < 0.001). The overall mortality was 27.8%, 34.0%, and 37.1% at 28, 56, and 84 days respectively. Mortality for patients with a Discriminant Function approximately 32 was greater in GM managed patients compared with GE at 28 (p = 0.006), 56 (p = 0.013), and 84 days (p = 0.036). CONCLUSION: Differences exist between the management of jaundiced ALD between GM and GE. Such differences may translate into improved outcomes.

Despite being established for the treatment of peptic ulcer (PU) disease, few studies have assessed the long-term effectiveness and economic benefits of Helicobacter pylori (Hp) eradication in primary care. Our aim was to investigate the effect of community based Hp eradication for patients with chronic peptic ulcer disease requiring maintenance acid suppression. The endpoints used were the patients dyspeptic symptoms and the requirement for the prescription of maintenance acid suppression therapy. The study area covered seven general practices in the Glasgow area. Patients with previously diagnosed peptic ulcer disease receiving prescribed acid suppression therapy were invited to a dyspepsia clinic. Hp status was assessed by Helisal rapid blood test (HRBT). Positive patients received Hp eradication therapy and were reviewed six weeks later. At six months a review of practice records was carried out, and two years after eradication a postal questionnaire was sent to participating patients. A total of 243 patients attended the initial clinic of which 81.9% were HRBT positive. 156 of 196 patients offered Hp eradication re-attended at six weeks. The per protocol eradication rate was 91.7%. After six months patients who had received eradication therapy were less likely to require maintenance acid suppression therapy compared with those to whom eradication was not given. Two years after treatment 76.5% of patients felt their symptoms were improved, but 42.2% were still receiving maintenance therapy. The estimated cost of treatment per month per patient had fallen from 20.23 Pounds to 9.39 Pounds after eradication. In conclusion we felt that community based Hp eradication for patients with chronic PU disease is effective, however it does not completely alleviate dyspepsia. Predictors of symptomatic response or of no longer requiring acid suppression therapy after two years were younger age of onset of PU disease and absence of pre-documented gastro-oesophageal reflux disease or hiatus hernia. Hp eradication improves patients symptoms, reduces the requirement for maintenance acid suppression and is cost-effective after two years follow-up in this targeted group.

BACKGROUND: The assessment of alcoholic hepatitis remains controversial. Several scores have been developed or used for this purpose. AIM: To study the use of the Glasgow Alcoholic Hepatitis Score (GAHS), the Discriminant Function (DF), Model for End-Stage Liver Disease (MELD) and the ABIC (age, bilirubin, INR and creatinine) scores as well as scores to assess corticosteroid response in the management of alcoholic hepatitis. METHODS: A total of 182 patients were studied prospectively. The GAHS, MELD, ABIC and DF scores were recorded on admission and serially over the first week of hospital management. Treatment with corticosteroids or pentoxifylline was considered if the GAHS was ≥9. RESULTS: There were no differences in outcome between favourable scores as per recommended cut-off points. Patients with a GAHS<9 had similar outcome whether their MELD, DF or ABIC scores were favourable or unfavourable. Treated patients with a GAHS≥9 had a significantly better 90-day outcome than those who did not: 58% and 30% respectively, P = 0.01; HR 0.33 (0.14, 0.78). Patients treated with corticosteroids who had a fall in bilirubin of 25% after a week of treatment had an improved survival: 82% compared with 44% [P = 0.0005: HR 3.70 (1.77, 7.73)]. The Lille Score or a 25% fall in bilirubin had greater sensitivities than an early change in bilirubin level (95% and 90% compared with 58%) to assess treatment response. CONCLUSIONS: In this single-centre study, a GAHS ≥9 identified patients who may benefit from treatment of alcoholic hepatitis. Intention-to-treat randomised-controlled trials using a GAHS ≥9 as the threshold for treatment are needed to validate these findings. Response to corticosteroids can be assessed using the Lille Score or by a 25% fall in bilirubin.

BACKGROUND: Guidelines exist for the management of alcohol withdrawal syndrome (AWS) but few have been assessed as to their suitability for general hospitals. The Glasgow Assessment and Management guideline for alcohol has been specifically developed for use in this context. AIM: To determine if this alcohol assessment guideline aids the management of AWS in general hospitals. DESIGN: The four components of the Glasgow Assessment and Management of Alcohol guideline were evaluated. This included the use of the Fast Alcohol Screening Test (FAST) to identify at risk patients, a risk stratification strategy to indicate fixed dose or symptom-triggered benzodiazepine treatment, the Glasgow Modified Alcohol Withdrawal Scale (GMAWS) for symptom-triggered treatment and a clear recommendation for vitamin prophylaxis of Wernicke's encephalopathy. METHODS: FAST scores were assessed along with the CAGE (cut down, annoyed, guilty and eye-opener) screening tool to ascertain if a single screening tool could identify hazardous and dependent drinking. The GMAWS and Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) were compared between two medical units. A staff survey of the two AWS tools was also carried out. RESULTS: FAST was able to identify both probable hazardous and dependent drinking. The GMAWS was reliable and gauged both physical and cognitive aspects of AWS. Staff generally preferred the GMAWS-based treatment as opposed to CIWA-Ar management and welcomed the Guideline as a whole. CONCLUSION: The Glasgow Guideline aids the management of patients with AWS in an acute hospital setting. It allows early identification of at risk patients and directs effective therapeutic intervention.

BACKGROUND: Variceal bleeding is an acute medical emergency with high mortality. Although less common than oesophageal variceal haemorrhage, gastric variceal bleeding is more severe and more difficult to control. The optimal therapy for gastric variceal bleeding remains unclear although endoscopic injection of N-Butyl-2-Cyanoacrylate (Histoacryl) glue is often used. However, its long-term efficacy is poorly described. We studied the immediate and long-term effects of Histoacryl glue injection as treatment for bleeding gastric varices in a large UK hospital. METHOD: Endoscopy records and case notes were used to identify patients receiving Histoacryl injection for gastric variceal bleeding over a 4-year period. RESULTS: Thirty-one patients received Histoacryl for gastric variceal bleeding. Seventy-four per cent patients had alcohol-related liver disease and 61% of cirrhotics were Childs Pugh grade B or C. Fifty-eight per cent were actively bleeding during the procedure with 100% haemostasis rates achieved. Two patients developed pyrexia within 24 h of injection settling with antibiotics. No other complications were encountered. Mean overall follow-up was 35 months, with mean follow-up of survivors 57 months. Forty-eight per cent patients had endoscopic ultrasound assessment of varices during follow-up with no effect on rebleeding rates. Thirteen per cent required subsequent transjugular intrahepatic portosystemic shunt placement. Gastric variceal rebleeding rate was 10% at 1 year and 16% in total. One- and two-year mortality was 23% and 35%, respectively. CONCLUSION: Endoscopic injection of Histoacryl glue appears to be a safe and effective treatment for gastric variceal bleeding. Further data are required to compare it with other therapies in this situation.
