‘Environmental’ susceptibility Dose-relationship (Becker et al, Hepatology 1996; Bellentani et al, Gut 1997) >60g/d; >120g/d
Type of drink? Debated/Unclear Pattern Binge/heavy drinking; Outside mealtimes
Diet-related? Obesity is most significant factor Single most important risk factor for progression in heavy drinkers (Naveau et al, 1997; Raynard et al 2002)
Identifying those with advanced ALD Liver disease is “silent” until end-stages Signs/symptoms of cirrhosis
Abnormal liver tests (↑ALT/AST, ↑GGT) – not particularly helpful/prognostic in ALD Prognostic markers (↓Alb, ↓plt, ↑BR, ↑PT) – usually endstage/advanced cirrhosis Abnormal liver imaging ?fatty liver ??cirrhosis Recent interest in identifying those who have progressive liver disease, before end-stage
Screening & Brief Intervention Screening adult population for risky alcohol consumption and providing feedback and brief advice results in a reduction in the amount of alcohol they consume (Kaner et al 2013) NICE PH 24 recommends alcohol screening should be integral part of healthcare practice Best current evidence from studies in primary care and ED with less evidence on the feasibility of routine implementation in other healthcare settings

Pharmacological alcohol withdrawal
Meta-analyses: BDZ are effective in reducing withdrawal severity, incidence of DTs and seizures Cochrane systematic review: BDZ better than placebo in preventing seizures; trend in favour BDZ vs others Fixed dosing – predetermined over specified number of days; ‘conventional wisdom’ but many patients undergo withdrawal with no pharmacotherapy may involve unnecessary sedation and hospitalisation
Symptom triggered – by signs/symptoms Allows individualised approach Regular assessment and monitoring using clinical experience or a clinical tool (eg CIWA-Ar)
Pharmacological management Acamprosate, naltrexone and disulfiram – all in NICE CG115. Acamprosate – avoid in severe hepatic impairment. Naltrexone – avoid in acute hepatitis, hepatic failure or severe impairment. Disulfiram – use with caution in hepatic impairment
Alcohol Guideline Screen all admissions with AUDIT-C If ≥ 5, refer to the ASN team (Brief intervention and full AUDIT) and complete the alcohol protocol
History as per NCEPOD recommendations FAST score to determine who needs pharmacological detoxification CIWA vs. symptom triggered Lorazepam vs. Chlordiazepoxide Thiamine guideline
Alcoholic hepatitis Progressive inflammatory liver injury associated with long-term heavy intake of ETOH Prevalence in Western society - approximately 25-30% 20-60 yrs F>M
Alcoholic hepatitis
Mild alcoholic hepatitis benign disorder Moderate/Severe Alcoholic hepatitis (hepatic encephalopathy, jaundice, or coagulopathy) High mortality 30-day mortality rate in patients hospitalized 15% Maddrey > 32 (severe) – up to 50% On-going ETOH persists and progresses to cirrhosis ETOH cessation Resolves slowly over weeks to months Sometimes without permanent sequelae Often with residual cirrhosis
Alcoholic hepatitis Maddrey score

Alcoholic hepatitis STOPAH trial Prednisolone improves 28 day mortality (13.9% compared to 18%) but no further impact Infections twice as common in people who start Prednisolone Reducing alcohol misuse just as bad as continuing to misuse

Acute Decompensation In somebody with chronic liver disease Ascites/variceal haemorrhage/HE/bacterial infection No organ failure
Acute on chronic liver failure ‘Acute deterioration (jaundice, HE +/- or HRS) of pre-existing, well compensated, chronic liver disease, usually related to a precipitating event and associated with increased mortality at 3 months due to multisystem organ failure (renal)’ Liver/Kidney/CVS/CNS/Haem/Resp
Management - Liver Care Bundle Decompensation
Jaundice Increasing ascites HE Renal impairment Sepsis/hypovolaemia GI bleeding
Management - Liver Care Bundle
Causes
GIB (variceal and non variceal) - antibiotics Infection (SBP) Alcoholic hepatitis PVT HCC Drugs (alcohol/opiates/NSAIDS) Ischaemia Dehydration Constipation
Management - Liver Care Bundle
Management - Liver Care Bundle
Management - NCEPOD
Deterioration in renal function should not be assumed to be hepatorenal syndrome, as other potential causes are often present and should be actively excluded Patients with ARLD who have deteriorating renal function should have diuretics stopped and have IV fluids even if peripheral oedema and ascites are present If ascites is present in patients presenting with decompensated ARLD, a diagnostic ascitic tap should be performed - coagulopathy is not a contraindication All patients with ARLD, who present with gastrointestinal bleeding, should be offered antibiotics and terlipressin until the outcome of the endoscopy is known Escalation of care should be actively pursued for patients with ARLD, who deteriorate acutely and whose background function is good
Scores Hospital mortality of cirrhotic patients in ICU variable 40% - > 80% Policies about admission to ICU Access to salvage transplantation
Need to identify patients who are most likely to benefit from aggressive treatment
Scores MELD (Bili/INR/Creatinine) CTP (Bili/albumin/INR/ascites/HE) Don’t take into account other organ/system failures (apart from renal) Not accurate at identifying sub group of patients who are likely to survive ICU admission
Scores
CLIF organ failure score Based on organ failures with cut off values specifically identified in cirrhotic patients Used to define grade of ACLF
Liver (Bilirubin) Renal (Creatinine/RRT/HRS) Neuro (grade of HE) Haem (INR) CVS (MAP/inotropes) Resp (SpO2)
CLIF Organ Failure score Helps to determine grade of ACLF
