Fibrosis Testing; New Options On The Way

There is a lot of jargon in here, hang with me.

Now about Cirrhosis: You have Hepatitis C and your doctor wants to check your liver for damage

The gold standard for diagnosis is a liver biopsy. This procedure takes place in the hospital. While you are under a local anesthetic, a physician uses a needle with grabbers to remove a tiny sample from your liver. Once the biopsy is completed the patient must lay flat for 6-8 hours to confirm a lack of bleeding, then go home and do nothing strenuous for days.

The sample is studied by a pathologist to assess liver scarring (fibrosis). While liver biopsies are invasive and do have inherent dangers (excessive bleeding, infection, hypotension), they also have variable results, depending on who is reading the results. It is better to have two pathologists study the specimen but this isn’t always practical.

There are promising alternative tests. New tests can assess the severity of the fibrosis in individuals at high risk of developing liver cirrhosis (e.g., chronic alcoholism, chronic viral hepatitis). These tests include breath testing, blood tests, and imaging techniques.

  • Ultrasound initially showed 94% accuracy, but that score has been downgraded. But in the US it is cheap and widely available
  • Ultrasound with contrast media is about 79% accurate but contrast media is expensive and not always used in compromised livers
  • Doppler checks the blood flow through the hepatic vein. This shows overlap of staging cirrhosis and therefore not a good choice
  • CT Scans look at the whole abdomen so subtleties can be missed
  • MRI has an accuracy of 80-89% but requires a high level of technique which is not always available clinically and is expensive
  • Biomarkers can establish cirrhosis and non-cirrhosis but not grades of scarring
  • Biomarkers: Indirect
    • Fibrotest is useful in diagnosing and grading fibrosis. This test has established measurements and may be used in place of a liver biopsy for patients with Hepatitis C
    • FIB4 uses a panel of biomarkers and can also be used instead of liver biopsy.
  • Biomarkers: Direct
    • HA (hyaluronic acid) normally occurs outside the circulatory system but can be evaluated by update in scarred vs normal livers. Scarred livers leave more HA behind while normal livers convert more to remove it from the blood.
    • PIIINP and PIINP
    • TIMP-1
    • YKL-40

All the tests listed above have varying degrees of accuracy but liver biopsy is still the standard for staging of scaring (fibrosis).1

Symptoms

The early stages of cirrhosis often produce no symptoms. As scar tissue replaces healthy cells, the liver begins to fail, and symptoms may become evident. The severity of symptoms depends on the extent of liver damage.

Because the liver is crucial for many metabolic activities, cirrhosis impacts a wide range of the body’s functions, including nutrient and hormone metabolism, blood clotting, and processing of ammonia and other toxic wastes. Many of the symptoms of cirrhosis are directly related to disruption of these functions. However, most of these symptoms can also be caused by other conditions, so it is important to consult with your doctor if you experience any of these symptoms, particularly if you have risk factors that increase your likelihood of developing cirrhosis.

Early symptoms of cirrhosis include:

  • Fatigue and weakness (related to anemia and altered nutrient metabolism)
  • Poor appetite
  • Depression
  • Nausea
  • Weight loss
  • In men: A decrease in liver metabolism can contribute to: Impotence; Reduced testicle size; Enlarged, tender breasts; and/or Loss of interest in sex—due to altered liver metabolism of sex hormones
  • Small, red spider-like blood vessels under the skin—caused by increased pressure in the tiny blood vessels due to liver congestion
  • Increased sensitivity to drugs—due to reduced ability of the liver to inactivate them

Symptoms become more pronounced as cirrhosis progresses. Later symptoms, some of which are due to complications, include:

  • Reddened or blotchy palms
  • Sleep disturbances
  • Ulcers
  • Fever and other signs of infection—due to altered immune function
  • Peripheral neuropathy
  • Frequent nosebleeds, skin bruising, or bleeding gums—resulting from decreased liver synthesis of clotting factors
  • Ascites —water retention and swelling abdomen caused by obstructed blood flow through the liver and reduced synthesis of the protein albumin
  • Bacterial peritonitis—infection of ascites causing abdominal pain and fever
  • Itching—caused by deposition of bile products in the skin
  • Jaundice —yellowing of the skin or eyes due to build-up of bile pigments (bilirubin)
  • Vomiting blood—due to swollen veins in the esophagus that burst
  • Encephalopathy and coma—mental changes, including forgetfulness, trouble concentrating, confusion, and agitation, caused by the build-up of ammonia in the blood
  • Decreased urine output and dark urine—caused by kidney dysfunction or failure
  • Liver cancer

This is an extensive list of symptoms but not complete. Each person is different. Remember that by taking care of your liver, some damage is reversible.2,3

Liver Fibrosis Testing Improvements

Don’t forget your lipstick

Cirrhosis is a chronic lesion with the accumulation of scar tissue and that alters the structure and function of the liver. Once a patient is cured of Hepatitis C, the danger is not over if the liver is heavily scarred. Currently there is no cure or reversal agent for cirrhosis short of a transplant.

 

 

As cirrhosis progresses, the liver tries to heal itself but the cycle builds scar tissue upon scar tissue and blood cannot flow through the liver. This causes a backup of blood which causes portal hypertension (high blood pressure of the liver). This is incompatible with life. When the liver cannot filter blood, the body compensates by growing vessels around the liver to move blood. And life threatening consequences occur. Frequent results are the pathological creation of blood vessels, ruptured veins in the stomach and esophagus, the inability to stop bleeding, liver cancer, therefore death.

In the past, treatments have targeted blood vessel growth to prevent new weak blood vessels that burst under pressure.

  • Drugs that stop blood vessel growth, do the same thing in the brain and throughout the body so the blocking of VEGF (vascular endothelial growth factor) receptors is damaging to normal blood vessel growth.
  • Most therapies are delivered by blood, but since the liver is scarred, the drugs bypass the liver and sight of inflammation and scar tissue.

Sounds complicated doesn’t it?  Well if you have received treatment for Hepatitis C, you already have a working knowledge of the liver.

Scientists say as the liver attempts to repair itself, the new nodules have high levels of CPEB4 protein and these new nodules form liver cancer cells. CBEP4 has been linked to blood vessel growth in brain and pancreatic cancers. By blocking CBEP4, normal vascular cells grow but the damaged nodules don’t. These experiments have been performed in cells in vitro, animals, and in sample tissue from patients with cirrhosis.

The researchers are working on the role of blocking proteins, and possible treatments for liver carcinomas. Currently liver carcinomas are the main liver cancer and the third deadliest cancer world-wide, with a 5-year survival rate of less than 10%.

In another study a team at The Salk Institute has identified a molecule, JQ1, which has shown promise in the prevention as well as reversal of liver fibrosis in animals. This molecule interferes with the master regulator of liver fibrosis, BRD4. This treatment is at the gene level, and works to block fibrosis formation for patients with cirrhosis from alcoholism and hepatitis. Currently JQ1 is a prototype of a new class of drugs tested in human clinical trials for various cancers.1,2

So Called Hepatitis C Science Panel on Bias

I read the transcript of a panel discussion regarding Hepatitis C and bias.  The facilitator was a Ph.D. who did not share her area of expertise. My bias is showing here.  Is she knowledgeable about Hepatitis C or bias,  or is she a facilitator for hire?  The panel was a registered nurse, a social worker and a patient, all with Hepatitis C.  Sounds promising.

But the summary of the discussion was this:

  • We need more money from the government to educate people with Hepatitis C about treatments.
  • We need more money from the government so we can support Hepatitis C patients in the same way HIV patients have been supported, with more teams (I am not clear as to what this statement means).
  • The patient’s affirmation was “Sticks and stones may break my bones but words will never hurt me” and “I learned a lot from a support group made of fellow Hepatitis C patients”.

I am with the patient, the tools are within as opposed to without. If solutions tie to outside money or the government, no progress is  made  and we are stuck. But if a new patient begins his journey with only a support group and he feels like shit (which he will), the danger of isolation is there and almost guaranteed.  I suggest adding a couple of strong friends or family members who can take turns helping you ride this bull, to keep you on for the eight seconds  (treatment duration). Forgive my analogy, I am from Texas where that makes sense. Two wonderful people for me were my husband and  the nurse. But, each patient experience is unique.  Keep trying until you find who and what helps you the most.

The pharmaceutical companies are reaching out to the masses.  They are talking about testing new treatments.  The companies are portraying patients as members of society, people who the general population can relate to. Not just the parrot heads and junkies as portrayed in the past.

parrothead BTW, I overheard my first hepatologist refer to Hep C patients in the waiting room as parrot heads (followers of Jimmy Buffett). That was my introduction to the label. I shared my thoughts with him about that descriptor for patients.

The pharmaceutical company  groundswell will reduce the stigma of having Hepatitis C.  Sure the motive is profit. So who cares?  Not a cured person like me (cured makes me sound like a ham). I worked in the pharmaceutical world for a quarter of a century. Research departments, when not linked to marketing, do great work. That is all I need to know. Let the insurance companies fight out the money issues. Give the insurance companies something to focus on other than patients. Oops, my damn bias is showing. I am curious to see how the “Affordable Care Act” (Obama Care) approaches  Hepatitis C.

As the panel patient points out, it is my efforts that will provide my shield from stereotypes. At least until the drug company marketing departments get the job done.

Hepatitis C: The Post Interferon World has Five Scoops of Good News

Hep C:  The Post Interferon World is Five Scoops of Good News

  1.  Increased number of patients screened and identified
  2.  Increased options for those who failed previous therapies
  3.  Improved patient compliance
  4.  Possibilities of patient-guided treatment
  5.  Decreased need for liver transplantation

  •   I quit writing my blog when I saw the first ad for Hepatitis C treatment on television. The representative people were not parrot heads or crack heads. They were typical ad people like Crestor or Nexium. These ads will bring people in for testing and treatment.  The early treatment decreases transplantation demands. But there is still a lot of Hepatitis C news, so I am back.

A friend of mine started round four of treatment three days ago and she is scared.  Because of Interferon and depression, she could not complete previous treatments. No pledge from me or her physician made a dent in her fear but time will show her. Her new protocol doesn’t call for Interferon, and she is on preventive anti-depression medication. The three drug cocktail for her is one of many not available six months ago, a bygone era.

I recall Fridays during treatment, Interferon injection days. Bathing and grooming started on Wednesdays. I could schedule most work meetings (via telephone) for Thursday and Friday. There is much compliance built around Interferon day. For me, there came the day I could not  work and Friday no longer mattered. Unfortunately leaving work isn’t always an available solution. I lost my career when I returned and I was still sick from drugs. Luckily I retired with benefits.  When I went through treatment # 2, I wasn’t working and could get all the rest required. In the post Interferon world of (mostly) no Interferon and ribavirin this may not be an issue, thus better patient compliance, and cure.

 

And now about patient-guided therapy and no you do not get to select from a menu. For those of you following genotyping using IL2b.  Researchers predict (I love that phrase) which treatments will work best in your body.  That will partially determine the treatment drugs for you, thus ruling out waste-of-time and money treatments.

Hep C Treatment: Do We Or Don’t We? And Who the Hell Does Egypt Know That We Don’t?

I’m going to  ask you to hang with me on this one.  It is a lesson in pharmaceutical pricing and what your insurance will/can pay. Medicaid can’t! 

I worked in Big Pharma Research and Medical Affairs for a quarter century.  So? I see pricing strategies for Hepatitis C treatment compounds and they will affect you.  Let’s look at:

  1. Pricing Strategies for Big Pharma, and they DO have one for who, how much, and how long
  2. How some get to bypass this pricing strategy entirely
  3. Why patients will unnecessarily suffer with this curable Hep C

These days you can’t swing a cat without uncovering a new treatment on the horizon!  Good! Right?  Mostly.  Big Pharma competitors have a short time on top and intend to make  as much profit for stakeholders (stock holders)as possible.  It is the job.

Remember when Vertex launched Incivek (telaprevir) fourteen months ago?  First new drug in forever.  All new patients were given Incivek along with the standard cocktail of Interferon/Ribavirin.  Vertex was the new darling in hepatology, for a year. Sales went from $76.1 Million Q 1 2013 to $44.3 Million Q 4 2013. Now they have dropped out of Hep C research because there is a new rock star launch; Gilead Sciences with Sovaldi (sofusbuvir).

“Record sales of a new hepatitis C drug, Sovaldi, pushed the first-quarter earnings of Gilead Sciences far beyond expectations, the company reported on Tuesday, Sovaldi (sofusbuvir), the company’s $1,000-a-pill medicine to treat hepatitis C, had sales of $2.27 billion in the first quarter, the company said in a statement. That beat an average of analyst estimates by more than $1 billion. The Foster City, California-based company also reported profit excluding certain items of $1.48 a share, beating by 56 cents the analysts’ average estimate (GILD:US). (Yes that is Billion not Million.) The hepatitis C sales are “above even the high end of buy-side expectations,” Mark Schoenebaum, an analyst with ISI Group LLC in New York, said in a note to clients. He called it the best drug introduction in history. Gilead, the world’s biggest makers of HIV drugs, yesterday reported total first-quarter revenue of $5 billion.

Gilead is awaiting U.S. regulatory approval of a two-drug combination with Sovaldi that does away with shots that boost the immune system, yet produce side effects. Company executives said they are aware of the price criticism and the sustainability of spending on the drug. “There are natural limits on what I think is appropriate for next generation products,” Chief Operating Officer John Milligan said yesterday on a conference call.”

 

“If cost were not a factor, we would want to treat the entire population,” said Dr. Rena Fox, a professor of medicine at the University of California, San Francisco. She said it was frustrating that “we finally get this great treatment and then we withhold it.” 

Ah,  my point exactly.

And then there is Egypt. Yes that Egypt.

On March 12 the Egyptians declared  that negotiations between the ministry and the American company were successful and Egypt will obtain the drug for only 1 percent of its price internationally, according to Al-Masry Al-Youm. Adawy, Minister.  The price of a one-month prescription in Egypt will cost $300 while in the U.S. it costs $28,000 a month. (Yes that is Hundred, not Thousand).  The full course will cost $13,000 instead of the $168,000 it costs in the U.S.. They agreed to support making hepatitis c a top priority and to intensify efforts to provide the required medicine at “affordable prices”. According to Reuters, Gilead said on March 22 that it was “pleased to have finalized an agreement” to provide the cure to Egypt, one of the countries with the highest rate of hepatitis C patients.

 

 

May 6, 2014:  Janssen Submits Supplemental New Drug Application to U.S. FDA for OLYSIO™ (Simeprevir) for Once-Daily Use in Combination with Sofosbuvir for 12 Weeks for the Treatment of Adult Patients with Genotype 1 Chronic Hepatitis C. AbbVie, Merck, Bristol-Meyers-Squibb and Johnson & Johnson have potential treatments on the horizon. This is why Gilead is gouging now.  Big Pharma calls it recouping research money. Some is profit too.   It’s all perspective.  Which a Hep C patient is sorely missing.

I shit you not. Thanks for hanging with me on Big Pharma Pricing.  Now you can teach MBA students.  I am feeling powerless though.  Maybe you know someone in Egypt.

One last thought:  I am clear of Hep C Virus after two years and I wish this for you.

Go see my friends at http://www.hepatitiscnews.com  They have great helpful news all the time!

Hepatitis C Treatment: The Big Sleep In The Rabbit Hole

Going through treatment of Hepatitis C, I suspended reality. 

My world became a rabbit hole.  More like a depressed Bugs Bunny than Alice.

Only my husband Spanky, the psychiatrist and the research nurse could check on me.  But frequently I pulled the hole in on myself and stayed there.  It was kinda weird.   I felt safe from others but not my crazy mind.  I couldn’t close the rabbit hole fast enough to keep out my mind.   Sometimes I felt like I was watching the world through a window but  I couldn’t remember what happened that day.

Memories of coming out of a bar when the sun is still bright, eewww.

Twice stolen from Edvard Munch

I used to wonder if other study patients felt the same as me.  I would watch in the waiting room.  But they weren’t giving up their secrets.  Each traveling with his own rabbit hole.

Rabbit Hole Urban Dictionary
Alice in…Metaphor for the conceptual path which is thought to lead to the true nature of reality. Infinitesimally deep and complex, venturing too far down is probably not that great of an idea.
An allusion to Lewis Carroll’s Alice in Wonderland. To go “down the rabbithole” is to enter a period of chaos or confusion.
Or to take acid, Deb
…….
Then the study ended.  As drugs began to leach out of my body, I felt like I took a year-long nap.  Only I wasn’t asleep.  I was waking from a little tiny world.  Like a newly released guest of the penal system or someone from the space station, I heard about stuff while in my pseudo-sleep but hadn’t really grasped it.  Politics, friends, life skills, I had to catch up on it all. This is more difficult than you think, trying to get past all the celebrity crap. Who “gets” celebrity crap?  I don’t but somebody must or it wouldn’t be ubiquitous.
Sometimes I want to crawl back down the rabbit hole.  During those times, I hang out in our guest room, my home during treatment.  It’s comforting in a psychiatric kind of way.  It took months to feel free of that need,  about four half-lives*  When I can’t sleep I still go in there.  It is normal to lie awake all night in the rabbit hole.
 I’m thinking of painting the rabbit hole room lavender (I don’t like lavender) or getting a new bed (I like the existing bed).  Dismantle the tangible rabbit hole.
*A half-life, t1/2, is the time it takes to remove 1/2 of a drug from your system.  To approach 100% drug removal takes about six half-lives.

A biological half-life or elimination half-life is the time it takes for a substance (drug, radioactive nuclide, or other) to lose one-half of its pharmacologic, physiologic, or radiological activity. In a medical context, the half-life may also describe the time that it takes for the concentration in blood plasma of a substance to reach one-half of its steady-state value (the “plasma half-life”)
