Transmission of Fatal H1N1 D225G/N Accelerates Concerns

Recently released H1N1 HA sequences have significantly accelerated pandemic concerns.  These sequences have either D225G, D225N, or both and produce a case fatality rate at or near 100% in many countries…. 

By the 100% fatality rate, Dr. Niman means that they are finding these changes in the tested fatal cases in some countries.  Keep in mind, these are small numbers of cases.  It does not mean that all cases with these changes prove fatal.  It might be more clear to say a large portion of the fatal cases show these changes in the infecting viruses.

[the] transmission and expansion of these fatal sequences in eastern Europe, including Russia have increased concerns, as has the "low reactor" status as determined by Mill Hill for a tested Ukraine sequence.

Some of the earliest sequences with D225G were in the United States last spring and were generally mild.  However, initial cases in the US were generally mild, which may have reflected low  viral loads infecting a naïve population…

"Low reactors" status means that the virus is not triggering the immune response expected due to changes in the structure of certain viral proteins (here, the influenza hemagglutinin proteins).  Immune responses target specific proteins and the target proteins’ structure is critical to the immune response.  Not all changes in a protein will greatly reduce its immunogenicity (ability to stimulate the immune response) but certain changes will.  The change from the wild-type (common) HA protein to the HA protein with the D225G marker appears to have this adverse effect--i.e., the altered viruses will not provoke the stronger immune response generated in response to the wild-type virus and/or the swine flu vaccine.   

These observations are cause for concern, not alarm.  The changes in the H1N1 virus are natural and predictable; Dr. Niman predicted these changes would occur.  

There already was interest in position 225 for a number of reasons.  D225N  was in seasonal H3N2 and linked to the fixing [establishment of widespread] of adamantine resistance (S31N), while D225G was in 1918 and 1919 samples and linked to a change in receptor binding domain specificities which would target subsets of cells in the lung.  In addition, the polymorphism [genetic change] was jumping from one genetic background to

Watching and Waiting

While the numbers of new cases of swine flu have been declining in many regions, including the United States, it is too early to know whether or not there will be subsequent waves of disease.

"Based on my experience with new diseases and the lessons learned from past pandemics, I think we should remain cautious and observe the evolution of the pandemic over the next six to 12 months before declaring victory," World Health Organization Director General Margaret Chan tells Swiss newspaper Le Temps. (World Health Official Says Swine Flu Still a Threat)

Although the WHO is remaining "cautious," changes in the virus’s genome that increase its virulence and resistance to Tamiflu are becoming more common.  Dr. Henry Niman, expert in flu virus evolution, believes another wave of illnesses will occur in early 2010.  In addition, he believes resistance to Tamiflu will become "fixed," similarly to how this genetic change evolved in the seasonal H1N1 virus.  (See Flu Update: Tamiflu resistance and Ukraine update, and Efficacy of Roche’s Flu Drug Tamiflu In Doubt, by David Phillips.)

WHO: H1N1 swine flu pandemic will stick around for another year

The World Health Organization warned government health authorities to remain vigilant on the H1N1 swine flu pandemic, saying the virus could mutate before vaccines can help it dissipate.

The World Health Organization is confident that the H1N1 swine flu pandemic will be under control in a year’s time – however, WHO officials warned global governments to remain vigilant for any mutations in the troublesome bug.

Dr. Niman believes this wave will be more severe than the previous two--but not due to random mutations. Rather, this will result from the process of recombination. Due to recombination, increasingly greater transmission of aggressive variants (D225G, D225E and D225N) and Tamiflu-resistant viruses will occur.

What’s new with the flu?

What’s new with the flu?

By Ilene with guest expert Dr. Henry Niman

Hospitals To Offer H1N1 Vaccines In South Korea

Tamiflu resistant swine flu virus strains, circulating along with the wild-type (more prevalent, Tamiflu sensitive) viruses, are increasing in numbers, as the pool of viruses continues to expand. This is not due to sporadic point mutations, nor is it to do a nefarious government plot. This is how nature works, and knowledge of viral evolution leads Dr. Niman to predict that the number of Tamiflu-resistant cases will continue to increase.

At the Recombinomics website, today, additional support for Dr. Niman’s theory is presented. Growing numbers in the country of resistant viruses are showing up in clusters, for instance in the Maryland/Virginia area and in Pennsylvania. These clusters of Tamiflu-resistant cases most likely reflect a larger pool of resistant viruses circulating in the U.S. and other countries. "These repeated reports of H274Y [i.e., genetic change causing Tamiflu-resistance] in geographic clusters, as well as transmission clusters, suggest that H274Y has passed a tipping point, and reports of H274Y will increase in the upcoming weeks." H1N1 Tamiflu Resistant Cluster in Pennsylvania,  

Separately, the ratio of D225G swine flu virus variant to wild-type variant may also be increasing.  As this variant may cause a more severe disease by binding in the lungs, rather than just in the upper airways, this is cause for concern. The more aggressive course of disease apparently occurring in Ukraine may be the result of an increasing ratio of a more virulent D225G virus to the wild-type virus. 

Further investigation is needed.  Because the wild-type virus binds in the upper respiratory system while the D225G variant binds in the lungs, tissue samples from individual patients should be taken from both regions in order to see more accurately how the virus is evolving.

Here are two of Dr. Niman’s recent updates discussing these developments.  For more, visit Dr. Niman at Recombinomics.

H1N1 Tamiflu Resistance Crosses Tipping Point
Recombinomics Commentary 03:07
December 4, 2009

Within the past two weeks, the number of documented cases of oseltamivir resistance in H1N1 viruses has risen from 57 to 96. Around one third of these cases occurred in patients whose immune systems were severely suppressed by haematological malignancy, aggressive chemotherapy for cancer, or post-transplant treatment. The clusters in the two hospital wards should be viewed in the context of

Flu News: D225G Follow-up

Swine Flu Precautions Continue For International Travellers

Dr. Henry Niman heads the research company Recombinomics Inc. Recombinomics has a small group of researchers who analyze the sequence data from viral samples isolated from patients diagnosed with swine flu.

I spoke with Dr. Niman last week about the evolution of the H1N1 virus as it circulates through the world’s population. These changes are natural—and Dr. Niman’s research on the subject allowed him to predict how the virus would change as infection rates increase and time goes on. The outbreak in Ukraine was initially described in many media reports as a new lung-blackening "mystery disease," leading to many false and misleading Internet stories. According to Dr. Niman, it was clear from the start that H1N1 was killing an unusually high number of previously healthy young adults. 

H1N1 infection seemed to cause more severe illness in Ukraine, and Ukraine officials asked the WHO for assistance. The WHO interfaced with Ukraine labs in Kiev and sent groups into western Ukraine to survey the problem and gather information. As part of the investigation, the WHO sent samples to Mill Hill in London, one of several regional centers that performs genetic analysis for the WHO.

Subsequently, the WHO issued several non-informative reports but held the sequences at Mill Hill for analysis. Dr. Niman wrote a number of commentaries on the rising death toll and the need to make the sequences public. He predicted the deaths would be associated with a receptor binding domain change in the wild-type H1N1 virus (the predominant virus) to a variant form, characterized by the D225G genetic marker. Wild-type H1N1 has a D at position 225 of the viral protein Hemagglutinin (HA), and is referred to as D225. The variant protein, D225G, has a genetic change causing a change in position 225 of the protein. "D" is the symbol for the aspartic acid which is present at position 225 of the wild-type protein. Glycine, symbol G, replaces aspartic acid in D225G variants. Hemagglutinin is one of two surface proteins projecting out from the surface of the virus. The function of the HA protein is to bind viral particles to susceptible cells in the host animal.

Weekly Market Recap Dec 16, 2018

Courtesy of Blain.

A significant selloff Friday had bears continuing to enjoy December and calls for the bulls for the Federal Reserve to save them.  It’s been a very long time since bears have had the upper hand for such an extended period.  Volatility continues to be very high and the charts continue to say “remain in safety”.  The Russell 2000 – the laggard of 2018 – broke a yearly low set in February and the S&P 500 broke October lows to create a “lower low”.

Karyn Cavanaugh, senior market strategist with Voya Investment Management, said that disappointing economic data out of China was the biggest driver of Friday’s losses. “The Chinese data was a dirt sandwich, not because it showed deceleration in the Chinese economy, but because it’s showing...
