mhudnall and Dr Berkson

[Upbeat]

I have waiting to see furter posts on your treatment with Dr Berkson.  How has it been going?  His work with Alpha Lipoic Acid and I believe LDN peeked my interest.   You were giving updated reports on your viral load and alt ast numbers.  Its been awhile and just curious as to where you stand now.

Here's the other two studies:

Study 3 -

Naltrexone: report of lack of hepatotoxicity in acute viral hepatitis, with a review of the literature.

Many clinicians appear to be concerned about the potential hepatotoxicity of the opiate antagonist naltrexone (NTX) and this may be one reason why it is not used more widely in treating both heroin and alcohol abusers. Some much-quoted early studies noted abnormalities in liver function tests (LFTs) in very obese patients taking high doses, although there was no evidence of clinically significant liver dysfunction. These concerns may be reinforced by advice in the UK product information sheet to perform LFTs before and during treatment, by high infection rates with hepatitis C virus (HCV) among injecting heroin addicts and by the frequency of abnormal LFTs in alcohol abusers. We describe a heroin abuser in whom clinical and laboratory manifestations of acute hepatitis B and C appeared a few days after the insertion of a subcutaneous naltrexone implant. A decision was made not to remove the implant but the hepatitis resolved completely and uneventfully well within the normal time-scale. A review of the literature indicates that even when given at much higher doses than are needed for treating heroin or alcohol abusers, there is no evidence that NTX causes clinically significant liver disease or exacerbates, even at high doses, serious pre-existing liver disease. During the past decade, NTX has been shown to be safe and effective in the treatment of pruritus associated with severe jaundice caused by severe and sometimes life-threatening cirrhosis and other liver diseases. Its safety, even in these extreme conditions, is particularly reassuring. We suggest that it may be more appropriate and economical to advise patients to report promptly any suspected side effects than to perform regular LFTs, which may be misleading.

Study 4 -

Safety of high-dose naltrexone treatment: hepatic transaminase profiles among outpatients.

Clin Neuropharmacol. 2006 Mar-Apr;29(2):77-9. Links

OBJECTIVES: This study was carried out to test the hypothesis that the hepatic safety profile of prolonged high-dose oral naltrexone (150 mg/d) is acceptable if over-the-counter analgesic use is restricted.

METHODS: Data from 41 consecutive outpatients with impulse-control disorder receiving naltrexone therapy were analyzed.

RESULTS: The mean treatment duration was 328 days and the mean naltrexone dose was 142 mg/d. Pretherapy/posttherapy mean aspartate transaminase and alanine transaminase levels in the naltrexone-alone group were 21.79/22.54 and 21.74/21.49 U, respectively (all within reference range).

CONCLUSIONS: Although limited in scope, these findings support the hypothesis that long-term use of high-dose oral naltrexone is safe in otherwise healthy patients with impulse-control disorders who restrict their intake of acetaminophen, aspirin, or nonaspirin nonsteroidal anti-inflammatory drugs (NSAID). However, confirming studies are needed.

In other words,

The sole basis for the black box warning is that in one study of obese patients given 300 mg doses of naltrexone, a small number of the study group developed elevated enzymes. I take 3 mg. Low dose naltrexone is between 1 mg and 4.5 mg. Regular dose naltrexone is 50 mg.

The studies above show that the one study from which the black box warning was founded have been contradicted in subsequent studies.

In the other thread, rocker brought up the "Blacj Box" FDA warning on natlrexone. I posted information there that the warning has been pretty thoroughly discredited, but I thought I should post it here as well.

Unfortunately, the FDA Naltrexone ‘black box’ warning about the possibility of liver issues can be very misleading when investigating Naltrexone or Low Dose Naltrexone because it does not provide the scope or dosage on which the warning is based.   The below is information about the Black Box warning – it is based on a clinical study where patients were taking extremely high dosages of Naltrexone (300 mg a day) and a sub-set of obese patients developed some liver anomalies.  Additionally, included below are 4 subsequent National Institutes of Health / National Library of Medicine Clinical Studies or Articles that specifically discuss the safety of Naltrexone to the liver, when used below 300 mg a day.  

Therefore, according to the below studies, the dosages of Low Dose Naltrexone (LDN), which are a very small fraction of either a regular or high dosage of Naltrexone, could be presumed to have no negative affect of the liver.   Note: The normal LDN dosage for adults is 4.5 mg or less per day, which is 1/66th of the maximum safe dosage level.  For children the normal dose is between 1 mg (1/300th of the maximum safe dosage) to 3 mg (1/100th of the maximum safe dosage).  

Also, the immune modulating affect of the opioid antagonist, Naltrexone, have been shown to improve the liver’s condition, including reducing ALT/AST levels, cholestasis-induced liver injury, liver fibrosis, and hepatitis.   Those clinical trails will be posted separately under the “Files” Yahoo Group Section (under the “Treatment-Low Dose Naltrexone” Folder).  

The following is an excerpt from the National Institutes of Health/National Library of Medicine/Daily Med Website (http://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?id=4682)

“Evidence of the hepatotoxic potential of naltrexone is derived primarily from a placebo controlled study in which naltrexone hydrochloride was administered to obese subjects at a dose approximately five-fold that recommended for the blockade of opiate receptors (300 mg per day)..”


The below four (4) clinical studies are quoted from the National Institutes of Health / National Library of Medicine/Pub Med Website:   (http://www.ncbi.nlm.nih.gov/sites/entrez?db=pubmed).  


Study 1 –

Study of hepatotoxicity of naltrexone in the treatment of alcoholism.

Alcohol. 2006 Feb;38(2):117-20. Links

Since a black box warning was issued by the Food and Drug Administration regarding the use of the opiate antagonist naltrexone (NTX), many clinicians have been concerned about current labeling of the potential hepatotoxicity risk of NTX in the treatment of opiate dependence and alcoholism. Despite many reports that demonstrated that the use of NTX did not cause elevation of liver enzymes, controversy concerning whether NTX is hepatotoxic continues. The current study monitored 74 alcoholic patients who received 25mg of NTX daily in the first week and then 50mg of NTX daily for the rest of the 12-week period. After the 12-week treatment, levels of the hepatic enzymes alanine aminotransferase (ALT) and aspartate aminotransferase (AST) did not show any elevation, except in one subject, and the results strongly support that NTX did not induce abnormalities in liver function tests or elevate the liver enzymes. Instead, a statistical significance of decreasing levels of ALT and AST in the liver was shown throughout the study. These findings provide further support that NTX is not hepatotoxic at the recommended daily dose and may be beneficial for patients with elevated liver enzymes.

Study 2 -  

High-dose naltrexone and liver function safety.

Am J Addict. 1997 Winter;6(1):21-9.Links

Marrazzi MA, Wroblewski JM, Kinzie J, Luby ED.

Studies have found naltrexone useful in the treatment of diseases other than opiate addiction in which endogenous opioids presumably play a role, such as alcoholism and eating disorders. Some of these studies involve high doses (100-200 mg bid). Because investigational studies with high doses (300 mg/day) reported clinically significant increases in liver enzyme levels, the authors measured a spectrum of liver function parameters in response to high doses of naltrexone in a double-blind, crossover trial (100 mg bid) followed by an open-label period (200 mg bid). They observed no adverse clinical or laboratory changes in liver function in association with high-dose naltrexone therapy in eating disorders.

Good luck to you Karen!

I'm sure we will all support your decision, whatever that may be.

When I was researching on the internet I found several Medical Doctors who use the same regime as Dr. Berkson, with a great deal of success.

to nygirl;

I appreciate your input and I value it. This is all pretty new to me and I can tell that you have been dealing with it and recovery for awhile and are being helpful. Thank you.
I do realize I don't have a lot of time to fool around and I am scheduled to have a consult with a hepatologist. I'm also checking with a local researcher regarding clinical trials for which I may be eligible. I just ordered some European ALA and even if I have to do the normal tx I will take some of the supplements to give my liver some additional relief.
Hospitals and Medical doctors are the reason I have the virus however, they were bust saving my life at the time so I'm not bashing them, they weren't testing for the virus when I contracted it.

I'm just casting about looking for something that will work and not wipe me out at the same time.

I thank you all for your valued input and will continue to come back for feedback.

Karen

Here in the US it is also legal, but by prescription only. However, the drug companies only make the regular dose form - 50 mg. So in the US, the prescription is faxed to a compounding pharmacy that converts the 50 mg form into low dose form 1-4.5 mg and ships it to your home. Still, the cost is only $30 per month without insurance.
