Cirrhosis and chronic liver failure How to manage flu
talkinghep Spring 2015: Edition 14 Genotypes and what they mean How to manage flu-like symptoms Cirrhosis and chronic liver failure Publisher: The Hepatitis Foundation of New Zealand After a somewhat chilly winter, we hope things are warming up in your region as spring approaches. On a positive note, at the recent World Hepatitis Day summit in Wellington on July 28th Professor Ed Gane noted that, if direct -acting anti-viral treatments (DAAs) are funded, it will become possible to eliminate hepatitis C in New Zealand. In August Pharmac issued a ‘request for information’ (RFI) relating to hepatitis C treatments and management. This suggests they are at least considering the issues around funding DAAs, a move which right now could help prevent over 150 hepatitis C-related deaths per year in New Zealand. The challenge for Pharmac remains how to afford these therapies. We certainly hope recent progress towards funding DAAs in Australia will flow through to New Zealand. Meantime, we encourage people living with hepatitis C to add your voice to calls for funding. Our hope is that one day soon you will be able to access these easy-to-tolerate 8 or 12week treatments and put hep C behind you. There have been several changes in Foundation staff recently. After 17 years, our CEO John Hornell decided to move on, having made a significant contribution to addressing viral hepatitis in New Zealand. Also moving on is our magazine editor, Melissa Wood, who is heading off to the UK on her OE. Melissa has done stellar work maintaining the high standard of this magazine over the past year. We wish to offer our ongoing encouragement and support to all people in New Zealand living with hepatitis C. If you would like to share your story as a way to support others, please contact Debbie Norris at the Foundation 07-5790923 or on 0800 33 20 10. We hope you enjoy this spring edition of the magazine.

The report by the House of Representatives Standing Committee on Health is titled The Silent Disease – Inquiry into Hepatitis C in Australia. The report comprised of more than one hundred submissions and five public hearings including input from community support groups and medical experts. They looked at treatment, testing, prevention and the cost of the virus. “The Inquiry has been a landmark moment for Australians living with hepatitis C. It allowed many people to make their voice heard and we thank the Committee for listening and acknowledging the diverse experiences of people impacted by hepatitis C,” said Acting CEO of Hepatitis Australia, Kevin Marriott. The committee has published many recommendations as a result of the inquiry. One recommendation was to create two specific campaigns. One campaign would target those who have a high risk of infection with a focus on prevention strategies and testing options. The other campaign would focus on people living with hepatitis C who may not have sought advice about treatment options after their initial diagnosis. programmes significantly reduce rates of hepatitis C transmission. The Committee also suggested exploring ways in which the patient experience in general practice could be improved for people living with hepatitis C. This included better information provision, improved treatment processes and patient counselling. Hepatitis Australia has welcomed the report but believes it still falls short in some important areas including affordable access to new generation anti-viral medicines. “We are disappointed that the report is silent on recommendations around new treatment options for hepatitis C, which have been deemed cost effective and are now awaiting a PBS listing date. These therapies offer the opportunity to transform lives and make hepatitis C a rare condition in our lifetime,” Mr Marriott said. Source: Hepatitis Australia The committee found the need for a more robust reporting and review framework, recommending that the Department of Health develops key performance indicators and annual reporting to measure progress against the targets in the National Hepatitis C Strategy. The committee recommended a national strategy be developed urgently to address blood-borne viruses in prisons. It pointed to evidence that needle and syringe NHS England boosts funding for hepatitis C treatment NHS England has agreed on funding for drugs for new hepatitis C treatments. It allows thousands of patients in England with hepatitis C-related cirrhosis to access new treatment options. The NHS in England has increased the budget for new virological cures for hepatitis C by a further £190 million. This is on top of the approximately £40 million which was allocated last year as part of its early access scheme to treat people with decompensated cirrhosis. Richard Jeavons, NHS England’s Director of Specialised Services, said, “At a time when funding is inevitably constrained across the NHS this is a huge new investment; in fact it’ll be the NHS’s single largest new treatment expansion this year. That’s why we’re also running a competitive tendering process in parallel, to seek to bring down the price of these very expensive page 4 new drugs.” Peter Moss, a Consultant and Chair of NHS England’s Infectious Diseases Clinical Reference Group, said, “The new anti-viral drugs being made available through this scheme offer a huge improvement in care for patients with hepatitis C-related liver cirrhosis. Now we are in a position to cure the large majority of patients and so to prevent further liver damage and premature death.” Source: nhs.uk www.england. news WHO adds hepatitis C drugs to essential list The World Health Organization (WHO) published a new edition of its Model List of Essential Medicines in May, which included the new ground-breaking treatments for hepatitis C. The move opens the way to improve access to the innovative hepatitis C medicines that show clear clinical benefits and could have enormous public health impact globally. The list is updated every two years by an expert committee, made up of recognised specialists from academia, research and the medical and pharmaceutical professions. This year, the committee underscored the urgent need to take action to promote equitable access and use of several new highly effective medicines, some of which are currently too costly even for highincome countries. The WHO has said prices for the new hepatitis C drugs need to drop to make them accessible to patients in poorer countries. “When new effective medicines emerge to safely treat serious and widespread diseases, it is vital to ensure that everyone who needs them can obtain them. Placing them on the WHO Essential Medicines List is a first step in that direction,” said WHO Director-General, Dr Margaret Chan. Many governments and institutions around the world are using the WHO list to guide the development of their own essential medicines lists. Every medicine listed has been vetted for efficacy, safety and quality. There has also been a comparative cost-effectiveness evaluation with other alternatives in the same class of medicines. The WHO’s latest Model List of Essential Medicines also included several new drugs for cancer and multi-drug resistant tuberculosis.

New South Wales Health confirmed poor hygiene practices at four dental clinics in Sydney have put many at risk of the blood-borne viruses. Authorities say they are now contacting all patients who had invasive procedures at the practices during the past decade. Health experts said the risk of infection was low, but urged any patients who had surgery or an invasive procedure at one of the practices to get a blood test as a precaution. of NSW. “These audits showed that there were some problems with the cleaning, sterilisation and storage of instruments in that it was not being done in compliance with the guidelines of the dental board of Australia. The dental board has interim immediate action, powers to suspend and impose conditions on dental practitioners and registration, if we believe it is appropriate to do so to protect the health and safety of the public.” Source: www.abc.net.au In total, six dentists have had their registrations suspended and another six have had conditions imposed on them. This was because of a number of breaches involving poor sterilisation and cleaning techniques over a number of years. The four practices involved include two called the Gentle Dentist at Campsie and Sussex Street in the city and two located at Surry Hills and Bondi Junction. “Public health investigations began that included audits of infection-control protocols and procedures within these clinics,” said Dr Shane Fryer of the Dental Council page 5 feature Your liver The liver is a very important organ. We cannot live without our liver. It performs over 500 different chemical functions and affects nearly every physiological process of the body. It processes virtually everything you eat, drink, breathe in or rub on your skin. vitamins and minerals until needed. The liver converts food into glucose, proteins and fats and helps spread nutrients around the body. It also cleans the blood by filtering alcohol and other toxic substances and removing these from the body. The liver is in the upper right-hand part of the abdomen, underneath the diaphragm and below the ribs. It is to the right of the stomach and above the gallbladder. The liver regulates most chemical levels in the blood and excretes a product called bile, which helps carry away waste product from the liver and aids digestion. Important proteins that affect the blood, such as albumin and clotting factors, are made by the liver. It is one of the main organs involved in our natural immunity because it releases important chemicals that activate immune responses when an infection is detected. The production and maintenance of hormones are also controlled by the liver. It is the largest organ inside the human body and weighs approximately 1.36 kg. It is reddish brown in colour and is divided into two main lobes. The gallbladder sits under the liver, along with parts of the pancreas and intestines. The liver and these organs work together to digest, absorb and process food. The liver stores energy by stockpiling sugar, carbohydrates, fat, page 6 The liver holds about 13 per cent of the body’s blood supply at any given moment. There are two distinct sources that supply blood to the liver: 1. Oxygenated blood flows into the liver through the hepatic artery, which is pumped by the heart. 2. Nutrient-rich blood flows into the liver from the intestines through the hepatic portal vein. Below the liver, where the hepatic artery and the portal vein come in, the bile duct comes out of the liver. Bile made in the liver flows out through this bile duct (which is a thin tube the size of a drinking straw) and goes down to the gut where it mixes with food. The gall bladder is a small greenish pear-shaped bag that hangs off the bile news Antioxidants and liver disease duct. It stores bile and squeezes it out into the gut at mealtime. Blood flows out of the top of the liver through three large veins called the hepatic veins, into a big vein called the inferior vena cava or IVC which goes to the heart. The liver can repair and rebuild itself. Even if only 25 per cent of it is still healthy, the organ can regenerate itself into a full liver again. However, if the liver becomes severely damaged, there comes a point at which it is no longer able to repair itself. Looking after your liver There are many things you can do to look after your liver. • Cut back on alcohol – Reducing your alcohol intake is one of the most important lifestyle changes you can make. Regular and heavy alcohol intake will increase liver damage. • Avoid unhealthy foods – Maintaining a healthy, wellbalanced diet and staying in a healthy weight range will prevent you from developing fatty liver or speeding up the progression of scarring. Giving your body the right nutrients is important for your well-being. • Cut back on cannabis - Heavy cannabis use can scar your liver. If you can stop cannabis use, you will slow the progression of liver damage. • Blood tests – Getting regular blood tests will help monitor your liver health Antioxidants are chemicals which minimise cellular damage. Antioxidants can benefit all people, but particularly those with liver or cell damage. The body manufactures some antioxidants while others come from food and supplements. Many brightly coloured fruit and vegetables, whole grains, nuts and legumes contain antioxidants. A great visible example of how antioxidants work is by comparing freshly sliced apple pieces. One piece of apple is plain and the other has lemon juice squeezed over it. The plain apple slice will start to degrade and brown quickly while the apple with lemon juice will take much longer to change colour. Lemon juice is rich in vitamin C, a potent antioxidant, which delays the oxidation or browning of the apple slice. Oxidation is a natural process that ensures the cells of our body are continuously evolving. While oxidation’s cycle of cell birth and cell death is nature’s way of keeping healthy via renewal, this process also creates potentially damaging free radicals. Free radicals are kept under control by antioxidants. The liver benefits from antioxidants in the same way a sliced apple with lemon juice is protected. Eating a variety of antioxidants can minimise liver cell damage and slow disease progression.

These usually last a few days to a week, however they can last longer. It can leave you feeling run-down. Flu-like symptoms are caused by a chemical called interferon. Interferon is a natural chemical produced by our immune systems. When we fight a cold or flu, we feel the effects of our interferon in the form of symptoms, such as fever, chills and aches. Flu-like symptoms • Fever – This is when the human body temperature goes above the normal range of 36–37 degrees celsius. An elevated body temperature is one of the ways our immune system attempts to fight infections. • Chills – Feelings of cold accompanied by shivering. Chills often accompany a fever. • Malaise – A general feeling of discomfort or being unwell. • Body aches – This is when your body feels physical pain. It is a sign your body is dealing with a condition that affects the body as a whole. • Headaches – A continuous pain felt in the head. • Fatigue – A tired feeling, such as exhaustion or feeling lethargic. • Weakness – When your body feels tired and you may not be able to move. • Night sweats – Sweating a lot during the night when your bedroom is not hot and without extra clothing or bed covers. All of the symptoms of the flu may not be present and the severity of the symptoms can differ from one person to another. page 8 Flu-like symptoms are a common side-effect of the current hepatitis C treatment of pegylated interferon and ribavirin. Manufactured interferon, called pegylated interferon, causes the same effects as our own internal interferon. Usually, the symptoms lessen after two or three weeks of taking the drug. Managing flu-like symptoms Coping with flu-like symptoms can be difficult and you can feel like there’s not much you can do. Your doctor may be able to prescribe some pain relief medication or anti-inflammatory medication to help with symptoms, such as fevers and aches. You may also be able to purchase over-the-counter medication which can help ease symptoms, however you must always follow manufacturer’s directions and never exceed the recommended dose. Some medications can impact your liver. Take a look at some of the tips on the next page to help you cope. Remember, if you aren’t feeling 100 per cent, take it easy and ask family and friends for help. Mild physical activity increases the blood flow to joints and muscles which may reduce stiffness. You may find the application of heat or cold packs to the joints and muscles helps in relieving some of the discomfort. Put layers of blankets and clothes at your bedside to manage chills. Eat a diet full of vitamins and minerals to give your body the best fuel. Get plenty of rest and listen to your body. Some exercise can boost energy levels. Try gentle stretching exercises. Some herbal products, such as herbal tea, may help some people feel better. Take a warm bath or shower. A wash cloth on the forehead or back of the neck may feel good. Drink plenty of water. Tips for managing flu-like symptoms If you are on hepatitis C treatment, inject pegylated interferon before bed to try and sleep through the worst of the discomfort. e Avoid stress, as it is associated with changes in the functioning of the immune cells. If you continue to have problems with flu-like symptoms speak to your health provider, who may be able to help. page 9 feature 3 5 1 Hepatitis C genotypes – 4 what do they mean? 2 6 Over many hundreds of years, as hepatitis C has spread around the world, it has evolved into different strains. There are six main strains (genotypes) and several minor strains within each genotype (subtypes). The oldest genotype is genotype 1, then 2, 3, 4, 5 and 6. Subtype 1b is the main strain in Northern Asia and Eastern Europe. Genotype 2 is common in North Asia and genotype 3 in the Indian subcontinent. Genotype 4 has developed in Egypt and accounts for almost 100 per cent of infections in the Middle East. Genotype 5 has developed in Southern Africa. Finally, genotype 6 has developed in South East Asia – predominantly Myanmar, Cambodia and Vietnam. Hepatitis C subtypes 1a and 3a arose in Asia and spread throughout the developed world largely as a result of the heroine trade via injecting drug use. They are now the most common genotypes in the UK, USA and Australasia. With increases in global travel and immigration, all genotypes are now found throughout the world. In New Zealand, 55 per cent of infected individuals have genotype 1 (most are subtype 1a), eight per cent have genotype 2, 35 per cent have genotype 3 and 1 per cent have genotype 4 and genotype 6. The relevance of hepatitis C genotype is changing with advances in treatment. There is no difference in severity of liver disease between the different genotypes – the risks of cirrhosis, liver cancer and transplant are similar across all genotypes. The major difference between page 10 different genotypes is the response to antiviral treatment. With pegylated interferon plus ribavirin, rates of cure were lowest in genotype 1 (45 per cent) and highest in genotypes 2 and 3 (80 per cent). The first generation of direct-acting antiviral treatment (the protease inhibitors boceprevir and telaprevir), when added to pegylated interferon and ribavirin, improve cure rates to almost 70 per cent. However, boceprevir and telaprevir only work against genotype 1. Most of the other first generation polymerase inhibitors, protease inhibitors and the NS5A inhibitors also work best against hepatitis C genotype 1 (partly because they were developed to do so). Hence, the first all-oral combinations (Gilead’s Harvoni – ledipasvir/sofosbuvir, AbbVie’s Viekira Pak – paretavir/ ombatsvir plus dasubavir) have the best results in patients infected with hepatitis C genotype 1 and worst results in genotype 3. The only direct-acting antivirals which work equally well against all genotypes are the Nucleotide NS5B inhibitors, of which the only approved one is sofosbuvir. The good news is that the newest protease inhibitors and the NS5A inhibitors also work equally well against all genotypes. At least four different “pangenotypic” combinations are now being trialled in patients (Gilead, AbbVie, Merck and Janssen). In the next three to five years, it is likely we will have combinations of two or three “pan-genotypic” direct-acting antivirals. When this happens, hepatitis C genotypes will have no relevance and testing will disappear. Call for action Last year, more than 150 New Zealanders died from complications of hepatitis C (HCV) cirrhosis and by 2030 that number will climb to 350. This increase reflects the aging of the infected population (around 50,000 with an average age of 50 years). The only way to prevent these deaths is through successful antiviral treatment. Last year, there were an estimated 1100 new HCV infections in New Zealand, almost all in people who inject drugs (PWID). This number has fallen significantly since the 1990s thanks to the introduction of successful harm-reduction strategies, such as needle exchange and opioid substitution therapy (methadone, suboxone). However, the only way to completely eliminate new infections in NZ will be through treatment as prevention (TasP) strategies where PWID are prioritised for antiviral treatment. The new oral antiviral therapies provide a unique opportunity for New Zealand, both to prevent deaths as well as to eliminate HCV infection. These new treatments are highly effective (>95% success) and extremely safe (no real side-effects and really suitable for everyone). They are also simple – all oral, only 8 or 12 weeks of 1-3 tablets per day and require little or no monitoring during treatment. They are ideally suited for community prescribing by GPs, CADS physicians and in prisons. By removing the need for individuals to attend frequent hospital clinics, community prescribing will also minimise the discrimination and stigmatisation and should maximise treatment uptake. But they are expensive and many governments are recommending funding only for those patients with the most advanced stages of liver disease, such as those with liver failure on the waiting list for transplant (<50 per year). But this will have little benefit because, paradoxically, treating and rescuing people in liver failure will actually increase the number who die from liver cancer (as this increases the number living with cirrhosis at risk of liver cancer). Several independent cost-effective analyses (such as the recent NICE from UK Department of Health) demonstrate that the biggest benefits come from treating patients at an earlier stage of their liver disease. Last month, the Australian PBAC (their equivalent of PHARMAC) recommended that (i) the new oral therapies be funded for ALL Australians with HCV regardless of disease severity and (ii) community prescribing should be allowed i.e. no need to go to hospital specialists. This forward-thinking decision opens the door to prescribing from trained GPs (which is already possible for HBV and HIV therapies). The Australian cabinet is expected to approve this funding later this year. This will also allow easier access for PWID, thereby allowing for the first time, treatment as prevention. PBAC sees this as a way to eliminate HCV from Australia within the next 25 years. The major contra-argument voiced here is the high price of the new therapies. But the price of these new therapies is something negotiated between the funders and the pharmaceutical companies. The increase in competition (Gilead/AbbVie/Merck with others to follow soon) has already resulted in big discounting around the world. It is time for PHARMAC and the pharmaceutical companies to start negotiating. Every year that treatment funding is delayed will result in hundreds of preventable deaths here in NZ. If we need a lesson, we need to look at the history of HIV treatment in New Zealand. The first death from AIDS was reported here in NZ in 1983. Over the next 10 years the numbers of deaths skyrocketed to more than 70 per year. But the rapid roll-out of effective new oral antivirals had a dramatic benefit, with reduction in deaths by >90% within 10 years. Every New Zealander living with HIV can now access the best oral antivirals available, and deaths from AIDS are now rare. These HIV therapies have also improved quality of life and productivity in people living with HIV. What a wonderful success story and a tribute to the advocates for the HIV-infected community, and the commitment from their physicians, the Ministry of Health and PHARMAC, who expedited these advances in HIV therapy into clinical practice. But HCV is a completely different story. Investment in HCV support services, research and treatment remain much lower than those provided for HIV, despite the fact that HCV affects 10 times as many New Zealanders than HIV. As for AIDS-related deaths, all deaths from HCV are preventable through effective oral antiviral therapy. But in 2015, no New Zealander living with HCV can access funded oral HCV therapy. The HCV community lacks effective advocacy in this country and desperately needs a voice to convince Government of the urgent need to fund these new therapies. All of us must join together to provide that voice. Written by Professor Ed Gane, New Zealand Liver Transplant Unit, Auckland Hospital. page 11 personal story Simon’s story I was diagnosed with hepatitis C just over three years ago as part of a routine check at a sexual health clinic. The result came as a complete shock. I can still hear those words the doctor spoke as he became the central character in one of those, thankfully rare, life-changing moments: “there seems to be a problem with one of your results.” A few months’ experimentation with drugs in my early 20s had probably exposed me to the virus. I had thought I’d been fairly careful and as this was over 20 years ago, I had thought I’d got away without any serious consequences of that brief, but now apparently significant, episode in my life. Even now, I’m still not convinced that this is the way that I contracted the virus. There is no way of telling how long it has been since initial infection though and I have learnt not to dwell too much on the source of the infection. As for ‘what to do next’, there was never any real doubt about undergoing treatment. As for ‘what to do next’, there was never any real doubt about undergoing treatment. As soon as I was diagnosed, the questions I asked were about treatment. I was initially told I would have to wait about six months for the chance to start treatment, which at the time seemed an eternity. However, this turned out to be an underestimation by the clinic staff and it eventually took two years. I found out a few weeks after diagnosis that I was genotype 1a. A fairly devastating discovery as I was fully aware that genotype is the primary indicator of treatment success, and this wasn’t good. Additionally it meant nearly a year’s worth of treatment. Soon after, I got a viral load result. It was in the millions and not a good result, this being the second strongest indicator of treatment success. Add to this my gender (wrong one), length of time of infection (too long) and age (too old). Things weren’t looking too good. However, I realised that all these factors were things that I couldn’t change and that I should only concentrate on things that I could change and aim to push those statistics up again. The stats for someone in my position I calculated at about 40 per cent. By careful preparation, I thought I could push this to 50 per cent and, given page 12 the success rate at the clinic where I was being treated, maybe push this higher, possibly up to 60 per cent. Things weren’t all that bad; there was some good news. The liver function tests were nearly all in the normal range, the exception being the Gamma-glutamyl transferase (GGT, an enzyme that is produced in the bile ducts) which was just above normal. An ultrasound scan showed no abnormalities, so the chances of having a cirrhotic liver were probably very low. I have always had a fairly good diet and never been a heavy drinker so I was confident that there was minimal liver damage, which would increase the chances of treatment success. The factors that I could do something about – in increasing my chances of success – would be in the preparation for the year ahead. My aim was to be in the best mental and physical condition that I could achieve and then to maintain that to keep the chances of success as high as possible. In other words, I was determined that, if my physiology would allow it, this treatment was going to work. I decided to try and enjoy the year as much as I could, to treat it as a year off, almost like a long holiday. My aim was to be in the best mental and physical condition that I could achieve and then to maintain that to keep the chances of success as high as possible. Having a positive attitude to treatment is, I believe, vital to getting through treatment and increasing my success rate. One of the things that I liked about my treatment clinic was that they shared this view. I also had access to a psychologist throughout the treatment to help with strategies to overcome negativity, low moods and other problems. There were other factors that helped in maintaining a positive attitude. Firstly, I was lucky that I did not have any major depression problems or other mental health problems that a lot of people have to cope with on treatment. I had also told a couple of friends about what I was going through and they were very supportive. Generally I didn’t tell friends and family simply because they didn’t need to know and their ignorance of what I was going through helped me to maintain a sense of normality. I also found that this stopped me focusing too deeply on the treatment experience. The clinic staff were very supportive – not only the treatment nurses and consultants but the administration staff and nurses were also very helpful. I used to actually enjoy visiting the clinic; it was as if I had acquired an extended family. This was particularly beneficial to me, as I was in the clinic at least once a week, partly because of my neutrophils count dropping to levels that were causing concern. To stay as fit as I could, I increased my involvement with a local walking club. It was not only the exercise that was important but the achievement of being able to regularly walk eight to 12 miles every week, despite being on treatment, gave me a psychological boost. The walking group has a very active, social aspect to it which I took an increasingly active part in. Meeting new people and doing new things turned out to be a central theme of my treatment experience. Meeting new people and doing new things turned out to be a central theme of my treatment experience. Another source of exercise was involvement with railway heritage. Before treatment began I was training to be a fireman on a local heritage steam railway. Unfortunately, this was one of the few things I had to give up. I did go regularly to help with the cleaning and maintenance of steam locomotives and still got out on the footplate on various occasions. I was not strong enough to be able to finish the training and qualify as a fireman; this is just about the only regret I have about treatment. For most of the treatment year I was regularly visiting a sauna and steam room at my local sports centre. Part of the reason was because it was very relaxing, but also as I thought it might stimulate the lymphatic system to expel the virus that can be found there. I have spoken to other people who have found saunas too much when on treatment, but I had no problem with them and found them extremely beneficial. I was not completely free from side-effects. I was very tired at times but rarely had to spend time in bed resting. I ensured that I had plenty of rest by learning to get this where I could, for example relaxing on the train or sitting in a coffee bar reading a book, or even a quick snooze while waiting to see my treatment nurse. I was lucky in not suffering any serious side-effects following the interferon injections, although I did tend to take them before going to bed, just in case. I did become very breathless because of anaemia and this was probably the worst part of the treatment. I had to be careful when out walking that there weren’t any serious hills to climb, as I could have problems ascending. I did occasionally suffer from ‘riba rage’ but kept it under control. Other side-effects were itchiness and rashes, which were annoying but not serious. I also tended to be easily confused and had problems concentrating. Again, not serious but annoying. I did however, go back to college to complete a certificate in counselling. This was very therapeutic as I confided in the other students on the course about what I was going through. It was helpful to check in every week and have the chance to discuss issues outside of the clinic. The only serious side-effect problem was that my neutrophils dropped to a level where I had to take an additional drug to boost these. This meant another injection each week, which seemed to make the breathlessness slightly worse, but luckily nothing more serious. After 48 weeks, I was relieved that it was all over. I had survived relatively unscathed, but there was a slight feeling of sadness in that I would not be in regular contact with the people at the clinic who cared for me. I feel that the time on treatment has taught me things about myself and overall it has actually been a positive experience that will help me in the future. I don’t yet know if this has worked. I will have a test in a few weeks’ time to determine the outcome. I really hope it’s good news and I can put this episode behind me. However, if the news isn’t good then I have no major anxieties about trying new treatment options in the future, as I have shown that I should be able to tolerate them and hopefully turn them into positive experiences. But I hope it has worked and I can direct my energies to other enterprises!

This edition deals with cirrhosis and describes the causes and investigations. The next article will focus on complications of cirrhosis. Cirrhosis is a progressive, diffuse, fibrosing and nodular condition that disrupts the normal architecture of the liver. Fibrosis was previously thought to be an irreversible scarring process formed in response to inflammation or direct toxic damage to the liver, but current evidence suggests fibrosis may be reversible. Any chronic damage to the liver can cause progression to cirrhosis. Although your liver can be injured in many ways, the final common pathway is inadequate healing resulting in hepatic parenchymal fibrosis. Approximately 80 to 90 per cent of the liver parenchyma must be destroyed before liver failure is manifested clinically. Causes of hepatic cirrhosis These causes often co-exist and result in accelerated disease. Most common causes Less common causes Alcohol (60 to 70%) Genetic metabolic disease Chronic hepatitis B or C (10%) Drugs and toxins NAFLD (10%) - most commonly resulting from obesity and metabolic syndrome Autoimmune chronic hepatitis types 1, 2 and 3 Hemochromatosis (5 to 10%) Biliary obstruction (5 to 10%) Primary or secondary biliary cirrhosis Idiopathic/miscellaneous Infection Vascular abnormalities Veno-occlusive disease Cirrhosis is often a silent disease, with most patients remaining asymptomatic until decompensation occurs. The condition is often discovered during a routine examination with laboratory or radiographic studies, or at autopsy. Early and well-compensated cirrhosis can be visible as anorexia and weight loss, weakness, fatigue and even osteoporosis as a result of vitamin D malabsorption and subsequent calcium deficiency. Decompensated disease (chronic liver failure) can result in complications, such as ascites, spontaneous bacterial peritonitis, hepatic encephalopathy and variceal bleeding from portal hypertension (discussed further in next issue). Clinical symptoms at presentation may include jaundice of the eyes or skin, pruritus, gastrointestinal bleeding, coagulopathy, increasing abdominal girth and mental status changes. Each of these clinical findings is the result of impaired hepatocellular function with or page 14 without physical obstruction secondary to cirrhosis. Because hepatic enzyme synthesis is required for drug metabolism, heightened sensitivity and medication toxicity may occur in patients with impaired hepatic enzyme synthesis. According to estimates from the United Network for Organ Sharing (UNOS), 75 to 80 per cent of cirrhosis cases can be prevented by eliminating alcohol abuse. Mortality rates in patients with alcoholic liver disease are considerably higher than in patients with other forms of cirrhosis. Normal liver Liver with cirrhosis Image source: depts.washington.edu/ Laboratory tests No serologic test can diagnose cirrhosis accurately. The term ‘liver function test’ is inaccurate because the test to determine the components in most standard liver tests do not reflect the function of the liver correctly. Although liver function tests may not correlate exactly with hepatic function, interpreting abnormal biochemical patterns together with the clinical picture may suggest certain liver diseases. When a liver abnormality is suspected or identified, other tests, such as a complete blood count with platelets and an INR, should be performed. Common tests in standard liver panels include the serum enzymes aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase, γ-glutamyl transferase (GGT), bilirubin and serum albumin. Radiological tests Although various radiographic studies may suggest the presence of cirrhosis, no test is considered a diagnostic standard. The major use of radiographic studies is to detect ascites, hepatosplenomegaly, hepatic or portal vein thrombosis and hepatocellular carcinoma, all of which strongly suggest cirrhosis. Ultrasound In people suspected to have cirrhosis, abdominal ultrasonography with/without doppler is a non-invasive and widely available modality that provides valuable and chronic liver failure Written by Dr Frank Weilert, Hepatologist at Waikato Hospital. information regarding the gross appearance of the liver and blood flow in the portal and hepatic veins. Ultrasonography should be the first radiographic study performed in the evaluation of cirrhosis because it is the least expensive and does not pose a radiation exposure risk. Nodularity, irregularity, increased echogenicity and atrophy are ultrasonographic hallmarks of cirrhosis. In advanced disease, the gross liver appears small and multinodular, ascites may be detected and doppler flow can be significantly decreased in the portal circulation. The discovery of hepatic nodules via ultrasonography warrants further evaluation because benign nodules (which have no harmful effect) and malignant nodules (which can be very harmful) can have similar ultrasonographic appearances. CT and magnetic resonance imaging (MRI) These are generally poor at detecting morphologic changes associated with early cirrhosis but they can accurately demonstrate nodularity and lobar atrophic and hypertrophic changes, as well as ascites and varices in advanced disease. They are used as followup investigation as a result of an abnormal screening ultrasound or when ultrasound has not given reliable information. Non-invasive evaluation (FibroScan and Non-invasive serum markers) These have been increasingly employed when the cause of chronic liver disease is clearly identifiable and staging of the severity of the liver injury is necessary. Depending on community or secondary care protocols, this usually includes the combination of AFP and ultrasound monitoring as well as regular clinical review and assessment of liver synthetic function. Liver biopsy Referral for liver biopsy should be considered after a thorough, non-invasive serologic and radiographic evaluation has failed to confirm a diagnosis of cirrhosis. The benefit of biopsy outweighs the risk and it is suggested that biopsy will have a favourable impact on the treatment of chronic liver disease. The sensitivity and specificity for an accurate diagnosis of cirrhosis and its etiology range from 80 to 100 per cent. Prognosis and outcome Prognosis and survival are markedly better in patients with compensated (stable) cirrhosis than in those with decompensated cirrhosis (chronic liver failure). Two main scoring systems are used to allow repeat assessment at clinic visits. Child-Turcotte-Pugh Score (CTP): The CTP or CP score is still widely used in the clinic and hospital setting as a simple prognostic tool. CTP scores can estimate the risk of death at three months and one to two-year survival. The CTP has been shown to accurately predict outcomes in patients with cirrhosis and portal hypertension. Because it is simple and does not require complicated calculation, clinicians have widely used this tool to assess the risk of mortality in cirrhotic patients. Calculation: The CTP scoring system incorporates five things, including serum bilirubin, serum albumin, prothrombin time, ascites and grade of encephalopathy. Based on the sum of the points from these five parameters, the patient is categorised into one of three CTP classes, either A, B, or C. Image source: depts.washington.edu/ Model for End-stage Liver Disease (MELD): The MELD score estimates the survival probability of a person with end-stage liver disease. It is usually used in the context when your doctor is considering referral to a liver transplant centre. The higher the MELD score, the lower the three-month survival. Calculation: The MELD score is based on three commonly obtained laboratory parameters, including serum bilirubin, serum creatinine and international normalized ratio (INR). Conclusion This series shows the importance of having liver disease properly assessed and staged so that appropriate prevention, treatment and surveillance can be organised. Prognosis of cirrhosis is still very good, as long as further damage is prevented, reversible causes are treated (or cured) and complications are actively looked for so that they can be diagnosed early. page 15 feature Differences between men and women with hepatitis C The hepatitis C virus doesn’t discriminate against gender - anyone can become infected. However, the virus does have a slightly different impact on women compared to men. There are also more men infected with hepatitis C. Approximately 60 per cent of the estimated 50,000 New Zealanders living with hepatitis C are male. Men and women can have different experiences in many aspects of their health. Some of the ways hepatitis C affects men and women differently are described below. susceptible to cirrhosis. However, this also means the protective effect decreases after menopause as the estrogen hormone decreases. Liver damage may occur faster in women after menopause. Another factor which influences liver damage is alcohol consumption. Men typically consume more alcohol than women. Alcohol is harmful to the liver and will speed up liver damage. Treatment Infection Research has shown women are more likely to spontaneously clear the virus. When a person comes into contact with hepatitis C there is a 15 to 25 per cent chance their body will clear it naturally in the first six months (acute stage). The 75 to 85 per cent of people who don’t clear the virus will develop life-long chronic hepatitis C. The percentage who clear the virus in the acute phase is higher in women. Although it is unknown why it is higher in women, it is thought that hormones may be partly responsible. Some research has shown males are more likely than females to engage in at-risk behaviours, such as injecting drugs. While this is debatable, it means men are more likely to be exposed to the virus. Alternatively, some women can be more at risk of hepatitis C exposure because of their job. Some predominantly female occupations may be more at risk of blood-toblood contact, such as nursing, housecleaning and working in the cosmetic industry. Liver damage Research has found men seem to be less protected against liver cirrhosis than women. This means liver damage occurs faster and more frequently in males. Men who have cirrhosis are five times more likely to develop liver cancer than women who have cirrhosis. Some experts believe the female hormone estrogen protects women from liver damage, making them less page 16 Women have been found to respond better than men to combination treatment of pegylated interferon and ribavirin. This means women are more likely to clear the virus after treatment. However, women who have gone through menopause are also less responsive than younger women to pegylated interferon and ribavirin. When on treatment for hepatitis C, women are more likely than men to develop anaemia. Anaemia is a condition when there is a deficiency of red cells or of haemoglobin in the blood. It is a common side-effect of ribavirin. Pregnancy Women with hepatitis C also have the added concern of passing the virus onto their children. However, there is a very low risk of transmitting hepatitis C to your baby while pregnant or during birth (less than 5 per cent chance). Hepatitis C transmission is more likely to happen when a mother has a high hepatitis C viral load, so it is important the doctor or midwife is aware you have hepatitis C in order to monitor your health and minimise the risk of infecting the baby. If the baby is born with hepatitis C, there is a 45 per cent chance they will clear the virus naturally within the first 12 months. Breastfeeding is safe for women with hepatitis C. Although very low levels of the virus have been detected in breast milk, it is destroyed in the stomach and there is no indication that breastfeeding passes on the virus. You may need to temporarily stop breastfeeding if you have cracked or bleeding nipples. foundation news CEO departure By now many of you will have heard that John Hornell recently decided to leave the Foundation. Over his 17 years with the Foundation, John served in a number of roles including CEO from 2002 to 2015. Under John’s leadership the Hepatitis Foundation has made a number of achievements, including the establishment and operation of the largest national Hepatitis B surveillance programme in the world. He initiated the development of the first Hepatitis C community pilot projects which have been instrumental in developing the National Hepatitis C Plan. Details of these two Ministry of Health-funded programmes can be found on our website: http://www. hepatitisfoundation.org.nz. Dr Kelly Barclay will continue as Acting-CEO until the process to appoint a new CEO is completed. World Hepatitis Day campaign launched On World Hepatitis Day, July 28, The Hepatitis Foundation of New Zealand started a new advertising campaign for hepatitis B and C across selected areas in New Zealand. The advertising began with radio ads and then spread into press adverts, mall shopalites, washroom posters and online advertising. The aim of the campaign was to raise awareness of hepatitis B or C within communities, and to encourage those at risk to get tested. The Foundation targeted those people who are most at risk of viral hepatitis with a new campaign. Approximately 150,000 people live with chronic hepatitis B or C in New Zealand. Nearly two-thirds of these people don’t realise they have chronic hepatitis. You may have moved on but did hepatitis move with you? Everyone has a past, some more exploratory than others. That past life may well be a memory now, but it’s possible you are still carrying a reminder, Hepatitis C. If you have ever shared a needle, had an unsterile piercing or tattoo, then you could have Hepatitis C. Getting tested for Hepatitis is easy. It’s better to know. Get tested.

However, the likely course of the medical condition was similar for the two groups. The new research was presented at the American Society of Clinical Oncology (ASCO) annual meeting during June in Chicago. The study had 815 participants with hepatocellular carcinoma, referred for treatment between 1992 and 2011. Hepatocellular carcinoma (HCC) is cancer that starts in the liver. It is a major cause of cancer death worldwide. A total of 343 hepatitis B patients and 472 hepatitis C patients were included in the study at a large U.S. cancer center. Marc Isamu Uemura and colleagues from the University of Texas evaluated pathological and clinical characteristics of the 815 patients. Three-quarters were men and the majority were Texas residents. portal thrombosis, a larger tumour size, extensive liver involvement, advanced CLIP stage and higher levels of alpha-fetoprotein (AFP), which is a diagnostic biomarker for liver cancer. However, results also showed people with hepatitis C were more likely to have cirrhosis, which is advanced scarring of the liver. The researchers concluded there are significant variations between hepatitis B and hepatitis C which may impact a patient’s eligibility for treatment, but not prognosis. Source: www.hivandhepatitis.com Results showed patients with hepatitis B developed hepatocellular carcinoma at a younger age than those with hepatitis C. On average, those with hepatitis B developed cancer at 57.4 years of age and those with hepatitis C at 61.3 years of age. Hepatitis B patients were also more likely than hepatitis C patients to have poorly differentiated tumours, Low risk of reinfection for injection drug users According to studies from Norway and Canada, reinfection rates after clearing the hepatitis C virus among people who inject drugs, as well as past drug users, are relatively low. The Norwegian study examined 138 people cured in a trial in 2004. Before being treated, 94 people had been injecting drug users. After seven years of follow-up, 37 per cent had started injecting drugs again. Thirteen per cent of all people who had resumed injecting drug use had become reinfected with hepatitis C, a total of 12 infections. The Canadian study, which took place in Montreal, looked at 338 people cured of hepatitis C at a clinic up to the end of 2013. Participants in the study were retested once a year after being cured. Of the 338 cured patients, 82 per cent had been exposed to hepatitis C through injecting drug use. A total of 22 participants, or six per cent of the group, became reinfected with hepatitis C after being cured. Other factors which were found to influence reinfection in the Canadian study were the lack page 18 of stable housing and hepatitis C and HIV coinfection. The findings from the studies suggested current and former injecting drug users who have been cured of hepatitis C require ongoing support to remain free of hepatitis C. Findings also indicated that fears of a high reinfection rate should not be used as a reason to withhold hepatitis C treatment from people who inject drugs.
