Traffic light test could help save lives
A simple 'traffic light' test that detects hidden liver fibrosis and cirrhosis in high risk populations could reduce harmful drinking rates and potentially prevent hundreds of alcohol-related deaths a year.
Devised by Dr Nick Sheron and colleagues at University of Southampton and Southampton General Hospital, the Southampton Traffic Light (STL) test, which costs about £50, could be used by GPs in the community.
Published in the October 2013 issue of the British Journal of General Practice (BJGP), the STL appeared to help reduce drinking rates in people with the highest risk of liver disease.
Liver disease develops silently without symptoms, and many people have no idea they have liver failure until it is too late - one third of people admitted to hospital with end-stage liver disease die within the first few months. However, a simple test available in primary care could diagnose disease much earlier, enabling those at risk to change their behaviour and save lives.
The STL test combines several different tests and clinical markers which are given a score that indicates the patient's likelihood of developing liver fibrosis and liver cirrhosis.*
The result comes in three colours: red means that the patient probably has liver scarring (fibrosis) and may even have cirrhosis, green means that there is no cirrhosis and the patient is highly unlikely to die from liver disease over the next five years. Amber means there is at least a 50:50 chance of scarring and patients are advised to reduce or avoid drinking to avert further disease progression.
During the study, funded by the National Institute for Health Research (NIHR) Research for Patient Benefit Programme, the STL test was used on 393 heavy drinkers identified through a questionnaire administered by their GP surgery. Results from the test showed there were 45 (12 per cent) red patients, 157 (40 per cent) amber and 191 (49 per cent) green. In the vast majority of patients (75 per cent) with a red test, the usual panel of liver blood tests were entirely normal, so there was no way that GPs would have been able to pick up the hidden liver disease and warn their patients of the impending problem.
Follow up questionnaires were sent to participants a year later to assess their drinking habits. Results showed that 65 per cent of the harmful/dependent drinkers with a red and amber STL results reduced drinking to a non-harmful amount, nearly twice as many as those with green STL (35 per cent) results.
Dr Nick Sheron, lead author and Head of Clinical Hepatology at the University of Southampton, and consultant hepatologist at Southampton General Hospital, said: "Patients are developing alcohol-related liver disease in the community but it is not being picked up until they are admitted to hospital, by which time it is too late for many of them. Since 1996 there have been about 4,000 admissions to Southampton General Hospital with cirrhosis and 75 per cent of them won't have known they had it.

Please note: I am not a doctor and I am only able to tell you what I have learned by doing my own research on the internet, and share with you the things that have worked for my husband. Please remember that Liver Cirrhosis is a very serious disease so I am not saying, do not see a doctor. Doctors have helped my
husband a lot. But I believe it is wise to do as much research as you can, and find out why
they are giving you every one of the medications and treatments they are giving you.
I believe they do not always know about or understand every treatment option that is available,
and there are many good options out there that can help.
Your health is ultimately your own responsibility, above anyone else's.
Best of luck to you!!!
