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

The Depression Road Goes On Forever and The Party Never Ends *

Hepatitis C and Depression: I should be weary of this subject, but I’m only weary of depression. Thirteen months ago I completed a clinical trial for Hepatitis C. I was cured, c-u-r-e-d.

 GS-US-256-0124-A Phase 2B, Trial Evaluating Using Combinations of Oral Antivirals (GS-5885, GS-9451), PegInterferon Α and Ribavirin In Treatment Experienced Subjects  With Chronic Genotype 1 Hepatitis C Virus Infection

Last month I went in for my one-year follow-up visit where it was confirmed “No Virus After One Year!”.  Okay, maybe it’s true.  Maybe. I answered questions about my mental well-being.  I felt great and said so.  Later I remembered that I felt great because I was on two anti-depressant drugs, Lexapro (escitalopram)  and Wellbutrin (bupropion XL) with a splash of trazodone at bedtime.

BTW, I think everyone should speak about their antidepressants. I know there’s a bunch of us out there.  Just look at the sales $$$.     I worked for Lilly when they launched Prozac.  Rather than get it for free, I paid at the retail pharmacy because I didn’t want anyone to know.  That’s Bull Corn.  Bull Corn?  Where did that come from?

Where was I?  So two weeks ago, my psychiatrist,  (who treats Hep C patients) began to decrease the Lexapro with the goal of decreasing my antidepressant load.  My scaffolding crumbled under me and I spiraled into an anxiety-ridden, weeping insomniac in just a few days and nights.

I've come undone
I’ve come undone

.So,  I am miserable and looking at increasing drugs.  My first thought was that I am FUBAR (Fucked Up Beyond All Reason/Recognition/Repair  military slang) and that’s that.  My second thought was to work closely with Dr _ who assures me that this is a minor setback. Minor to someone else maybe. How quickly I become self-absorbed.

Now, after 400 words, the reason for this blog.  Today I received this article from  Medscape.

 Psychiatric Treatment Considerations With Direct Acting Antivirals in Hepatitis C   Sanjeev Sockalingam, Alice Tseng, Pierre Giguere, David Wong
BMC Gastroenterol. 2013;13(86)

(Newly published articles in my areas of interest for August 9, 2013: Medscape)

Can’t resist the title can you?  I know I can’t.

Being a Doctor of Pharmacy and a scientist, I love articles like this. It takes my entire nineteen years of schooling to follow the data dump. Gastroenterologists and Psychiatrists won’t read this article. It falls into a discrete category that gets filtered out during literature searches. DAAs means previrs ( boceprevir / telaprevir).

Abstract

Background Despite recent advances in hepatitis C (HCV) treatment, specifically the addition of direct acting antivirals (DAAs), pegylated interferon-alpha remains the backbone of HCV therapy. Therefore, the impact of DAAs on the management of co-morbid psychiatric illness and neuropsychiatric sequelae remains an ongoing concern during HCV therapy. This paper provides a review of the neuropsychiatric adverse effects of DAAs and drug-drug interactions (DDIs) between DAAs and psychiatric medications.

Methods We conducted a PubMed search using relevant search terms and hand searched reference lists of related review articles. In addition, we searched abstracts for major hepatology conferences and contacted respective pharmaceutical companies for additional studies.

Results Limited data is available on the neuropsychiatric adverse effects of DAAs; however, data from major clinical trials suggest that DAAs have minimal neuropsychiatric risk. DAAs can potentially interact with a variety of psychotropic agents via cytochrome P450 and p-glycoprotein interactions. Triazolam, oral midazolam, St. John’s Wort, carbamazepine and pimozide, are contraindicated with DAAs. DDIs between DAAs and antidepressants, anxiolytics, hypnotics, mood stabilizers, antipsychotics and treatments for opioid dependence are summarized.

Conclusions Although DAAs do not add significant neuropsychiatric risk, the potential for DDIs is high. Consideration of DDIs is paramount to improving medication adherence and mitigating adverse effects during HCV therapy.

So the abstract  (I saved you from the entire article)  kinda says: We don’t know enough to draw any conclusions so we caution you when using any drugs metabolized by the liver, including antidepressants. Terms: pharmacokinetics (where the drug goes in your body and how your body changes it to water-soluble (pee), or fat-soluble (poop) to get rid of the drug:  pharmacodynamics , what the drug does to your body to heal you and how it does it. This is for one drug. Think about a bunch of drugs where the liver and maybe kidneys do not work well.  There is a traffic jam and a couple of fights at the entry to your liver and the drugs build up in your blood.   Crash.

This is a year of my life

CPY 450 System, took me years

And so I say to you what any good or bad pharmacist would say:  “Caveat Emptor”.  Actually,  the pharmacist will put warning stickers all over the bottle and give you a packet of small print information.  Then she will make you sign that you have been counseled.

Beware the Jabberwok

Things Not To Say to Someone Who Just Completed Hepatitis C Treatment

Now What?

Now What?

  • You were in treatment?  I just thought you were aging badly.
  • Now make sure you don’t get it again (my personal favorite)
  • How do you celebrate without alcohol?
  • How can you be sure you are cured? I’ve heard it comes back.
  • I heard of a guy that went two years then his liver blew up.
  • Some guy finished treatment then killed himself.
  • Can you talk to my husband?  He won’t quit drinking and drugging.
  • I saw a website that says St John’s Wort works better.
  • Want to volunteer at the hospice?
  • Too bad you have to give up your handicap placard.
  • Glad you finished.  Maybe you won’t be such a moody A Hole now.
  • You should have waited for newer treatments.  They are better.
  • Now, shut up about your symptoms.
  • Good, now get off your butt and do something.
  • Now what?

Hepatitis C: Been A Long Time Leaving But’ll Be A Long Time Gone

My dad was a Waylon Jennings man.  I think he liked the big FU that Waylon projected.  I paraphrase Waylon.  “I been a long time leaving Hepatitis C, but I’ll be a long time gone”

So after three years of treatment-plus the maybe five years of falling apart, I get a voice mail that says “Hi Deb, this is the message you’ve been waiting for.  Still no detectable virus, so you’re cured.  See you in 24 weeks”.  Glad I go back in 24 weeks, so I can ween myself off of the Texas Medical Center.  This follow-up lasts a couple of years.  Now what?  I don’t care.  Today I am neither a patient nor a scientist.

Yep, I’m doing this in Kerala

I can do anything I want.  I will start with a trip to India this week. No shit.  BTW I tried to say this without the word shit, but it didn’t sound like me.  Waylon and India.  That’s all I got to say for now.

Hepatitis C: Beware the Jabberwok

 Hepatitis C:  Beware the Jabberwok

Through the Looking Glass

‘Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.

‘Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch!’

He took his vorpal sword in hand:
Long time the manxome foe he sought 
So rested he by the Tumtum tree,
And stood a while in thought.

And, as in uffish thought he stood,
The Jabberwock, with eyes of flame,
Came whiffling through the tulgey wood,
And burbled as it came!

One two! One two! And through and through
The vorpal blade went snicker-snack!
He left it dead, and with its head
He went galumphing back.

‘And hast thou slain the Jabberwock?
Come to my arms, my beamish boy!
Oh frabjous day! Callooh! Callay!’
He chortled in his joy.

‘Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.    

  

If you listen to a scientific lecture for an hour, you can begin to believe nonsense is science, but don’t.

I believe that the average Hep C patient (whoever that is) has a triple cross to bear.     1. You feel like shit on a stick  2. You have to go to unimaginable places like a liver biopsy suite and 3.You are thrown into a parallel universe where the language is almost understandable, but not really. It’s Jabberwok.

I was listening to a lecture yesterday on Hepatitis A through E. I was reading the slides as Dr. Nice Lady from pharmacy was talking.  And then I heard it:Hepatitis B and C are predominately associated with percutaneous and permucosal transmission”.  Translation:  Hep B and C can be caught through blood and through sexual contact.  Permucosal  is medical lingo for via mucous membranes.  The problem was that fifty pharmacists were about to  leave the lecture and tell their worlds that you can catch Hep C through sex.  I couldn’t let that happen so I said through the chat box “Hep C can be caught through sexual contact?  Is this new information?”  She said no, you are right to point that out, it is not transmitted that way.  So why did she say it?  The slide looked better that way.

In reality, the way one gets Hep C through sex is through rough sex and I mean rough.  Percutaneous means blood transmission.  I will pause here so that you create your own image.

Now I was willing to let it slide when she said that Hepatitis A and E were transmitted through the oral-fecal route.  In reality it is fecal-oral route.  Think about that for a moment.  But my point is that there is a lot of slightly non-true information out there.  What can you do about it?  Ask questions wherever you go.  Even if you have asked the same question before.  Remember how your doctor’s office always has that sign in English and Spanish that says Questions/Pregunta?  They really want you to ask.

Boy, did spellcheck light up Jabberwok!

Viral Hepatitis:  Keeping Your Patients Safe www.freece.com

Hepatitis C: Does “No Detectable Virus” Equal Cure Or Is It Smoke?

Am I cured or is it just smoke?

Hepatitis C cure?

 If my hepatitis C virus test shows non-detectable virus 6 months after the end of treatment, am I negative?  Will I  stay negative?  Am I cured?  In the recent past only “non-detectable virus” was declared. Now doctors are adding “cure” to the jargon.  This is with the addition of Incivek and Victrelis, and depending on the discussion.  No two clinical trials are alike and so Hepatitis C researchers use (they say utilize) sustained viralogical response (SVR) to compare outcomes.  Most trial design is by the company developing the drug.  One goal is to ask the study questions just right to get scientific and marketable answers.  “GodZillapravir had a non-detectable  SVR at weeks 12 and 24 in 85% of patients including those with mild to moderate cirrhosis”. “KingKongViracide cleared Hepatitis C virus in 94% of patients at 24 weeks including children 12 to 18 years of age”.  Which is the better drug?  You can’t tell by the claims because two different patient populations and time lines .  But they have  SVR in common.  That is why researchers use SVR.  BTW I made up the examples.  Now don’t get down on industry just yet.  Academics are accountable to department heads and medical journals.  That can be as powerful as a stockholder.

Industry is different: Stock holders in towers

When it comes to patients , the word “Cure” has emerged because research shows that if you have no detectable virus after six months, the chances of Hep C returning is about 1-2%.  And the argument is that it was never cleared, just so low that it was undetectable.

So with Hepatitis what does this mean?

Successful treatment for Hepatitis C hasn’t been available for long, so doctors are just starting to understand the long-term outcomes.  Do cancer survivors say cured?  I think they say  cancer-free for 2 years, 5 years, etc.  Am I a Hepatitis C survivor or am I cured?  Is it still a pre-existing condition?   A research site, not insurance, paid for my treatments.  But my medical records say Hepatitis C.

So at 24 weeks can I tell the insurance company that I no longer have Hepatitis C?  I can’t find the answer to that question without talking to them directly. I will wait until 2014 (I think that is the year) when they cannot cancel me for pre-existing conditions.  Insurance politics are so confusing, I am not clear if that stipulation is on the potential chopping block.  In speaking with my mental  Dr, I realize that I do not have confidence in my treatment and I am waiting for it to come back.  I am at 4 1/2 months post treatment.   I have been Hep C positive for so long, I don’t know how to have a future in which chronic debilitating illness isn’t a key player.  What is the world like with only mild hypertension and chronic but manageable depression?

Below is a good article for defining end-of-treatment terms, although it is a bit dated.  Newer drugs are not addressed but the terms are the same.

 Hepatitis C: What Is a Sustained Virologic Response or “SVR”? (From Charles  Daniel, former About.com GuideSVR) 

SVR is the closest you’ll get to “a cure” for hepatitis C.
 Sustained virologic response, or SVR, is the goal of hepatitis C treatment.  Conventional treatment (a combination of interferon and ribavirin) doesn’t  necessarily eliminate the hepatitis C virus from your liver. It can, however,  suppress the virus to undetectable levels for an extended period of time. In clinical language, this is called a “sustained virologic response,” or sustained  response. It means that during the six months after you complete treatment,  there is no detectable hepatitis C virus in your blood.                                         SVR is a good thing.
Studies have shown that with a six-month SVR (which means no detectable virus in your blood for six months after finishing treatment), relapse occurred in only 1-2% of patients. So, for every 100 people who finished treatment and attained SVR, the virus will return in only 2 of them. However, for these people, the
virus never really left. The medicine was able to eliminate most of the virus (so much that medical tests couldn’t detect it), but after treatment ended, for whatever reason the virus was able to continue replicating itself.

Early SVR is beneficial
Since the liver has incredible regenerative ability, achieving SVR
 as quickly as possible is important. This is important because some liver damage can be reversed if the cause of the damage is removed. After SVR is reached and depending on the degree of damage from the virus, the risk of hepatocellular cancer is reduced and about 25% of people see an improvement in fibrosis.

SVR compares one treatment to another. For those in treatment, SVR is the goal. However, for physicians and scientists researching new hepatitis treatments, SVR is also used to evaluate new medicines and compare them with proven therapies.
 For example, depending on the genotype, treatment with interferon alone usually achieves SVR in 15% of the patients. When interferon is combined with ribavirin in the same genotype, SVR is increased to 70% in some people.
