Hong Kong: Monitoring of human swine influenza virus (11/23/09)

Hong Kong: Monitoring of human swine influenza virus (11/23/09)

A spokesman for the Department of Health (DH) today (November 23) said that the department's Public Health Laboratory Service Branch (PHLSB) had detected one human swine influenza (HSI) virus which had the same mutation as the one detected in Norway recently.

Following Norway's announcement and obtaining information about the nature of the mutation, DH examined the genetic sequence of HSI viruses that it had tested in its monitoring system.

The spokesman said that out of the 123 sequences studied, one sample showed the same mutation as the Norway strain.

Mutations are frequently encountered in influenza viruses.

According to the World Health Organization (WHO), the same mutation of the virus has been found in other countries, including Brazil, China, Japan, Mexico, Ukraine and the United States, the spokesman said.

He added that no evidence suggested that these mutations were leading to an unusual increase in the number of HSI infections or a greater number of severe or fatal cases.

The virus was isolated from the specimen taken from a one-year-old boy who developed flu-like symptoms on July 22.

His respiratory specimen taken on July 25 tested positive for HSI.

He was admitted to Prince of Wales Hospital on July 25 and discharged on July 28.

The boy recovered completely and his family members were asymptomatic.

"The virus with this mutation remained sensitive to antiviral drugs, oseltamivir (Tamiflu) and zanamivir (Relenza).

"According to the World Health Organization, studies showed that the currently available pandemic vaccines conferred protection," the spokesman said.

The PHLSB will closely monitor influenza viruses worldwide and remain vigilant for any further changes in the virus that may have public health significance.

Re: Add China to the Norway mutation list

Hong Kong variant of A stream is now alarming
2009-11-24

【Ta Kung Pao, Reuters After Norway appear life-threatening variants of H1N1 influenza viruses in Hong Kong which is the first variant of the virus, once again sounded the alarm prevention. Yesterday, the Department of Health announced that, in cases valued at more than one genetic testing found that a one-year-old boy diagnosed with variants of the virus genetic samples. An infectious disease doctor said variants of influenza virus, easy to expect a variant of sporadic cases will start to appear, it is recommended to prevent high-risk persons vaccinated.

Recently, Norway appears three life-threatening cases of H1N1 influenza virus variants. Hong Kong Department of Health, the Norwegian health sector in response to data released by re-examination 123 gene sequences of influenza A H1N1 test samples to find out whether the flu virus in Hong Kong have a similar variant of the situation. Yesterday, the Department of Health found that one sample appeared identical with the Norwegian variant of flu viruses.

By the end of July have been discharged

It is understood that the disease strain is from a sample of a one-year-old boy separated, he appeared in the July 22 influenza-like symptoms, three days after the Prince of Wales Hospital in Sha Tin. Laboratory results showed that his respiratory sample positive for H1N1 influenza A virus response, July 28 and discharged, and has fully recovered, his family, and no flu symptoms. Department of Health said the disease strain pairs of Tamiflu and Relenza has encountered resistance.

Department of Health said that there is no evidence to suggest that variants of H1N1 influenza A virus, H1N1 influenza A infection will lead to an unusual increase in cases, or even more serious or death case was reported. According to WHO data, including Brazil, Mainland China, Japan, Mexico, Ukraine and the United States have found the same mutation of the virus, while the variants of influenza viruses is frequent.

Hong Kong's first H1N1 influenza virus variants is that there may be more potential cases. Zhongshan University College of Medicine and Professor of Respiratory Therapy Director of Hsu Shu-chang said that the characteristics of variants of influenza viruses in Hong Kong's case is a normal variant of a virus and is expected to be gradually discovered a variant of sporadic cases. He believes that it is normal variants of influenza virus, the virus genome will not necessarily "change evil" spread of the virus for some time, there will be a slight genetic change, the only big concern is that genetic drift, the need to observe the virus for some time.

Hong Kong will soon enter the second wave of H1N1 influenza epidemic, he said, the public need not worry too much about variants of the virus, the current anti-flu drugs, such as Tamiflu, Relenza, there is still a certain efficacy, and to remind high-risk people who were inoculated against vaccine.

Re: Hong Kong - 225G mutation found

2009-11-23

Hong Kong reports 225G in Fully Recovered 1 Year Old Male from July at Prince of Wales Hospital

225G is not new.

The public perception of 225G and the media linkage to hemorrhagic pneumonia is new.

These Hydra Effect viral backgrounds carrying 225G within ΣPF11 are, in fact, very dangerous strains for what they are doing now and, more importantly, for where they are going . . . no question exists about that risk tendency. The only question is why hasn't the science community driven the clinical linkages to the forefront before this week? Fatal outcomes have been documented on record since July in multiple cases from Brasil.

Prince of Wales Hospital in Hong Kong, notable for their handling of the SARS epidemic and additional limited waves in the following years, has released data today concerning the very popular polymorphism, 225G. A one year old male child presented on July 25 and was reported to have exhibited symptoms as early as July 22. The report indicates a discharge 3 days after admittance with recovery.

One week of illness. One important discussion point for those characterising 225G as essentially a high morbidity polymorphism.

We certainly do not impeach the idea of higher morbidity. Biasing any induction solely on singular reports like this Hong Kong case is errant logic, but the evidence does suggest that patience and some exertion may be required to accurately surmise the effector mechanisms of PF11 with and without the pairing of 206T and 225G. Proceeding with a data basis will slowly build the well-supported pyramidal steps required to undertake a capstone solution against this genetically simple, yet clinically complex disease.

We expect to see another half dozen of the major research areas also report 225G, not because the change is new, but because they’ve had the reins lightened, the leash lengthened, on this particular revision and are now encouraged to report this popular news item. This polymorphism, 225G, is seeded around the world.

225G is not as wide or as deeply penetrating as 225E. Our team expected and predicted this Hydra Effect with multiple, human-fit strains on diverse genetic backgrounds that would co-circulate in an emerging pandemic due to Influenza Flux during the pre-PF11<sub>Ω</sub> phases. An enterprising question might be, “How many Hydra strains will co-circulate in each phase?”

Numerous sub-species are spreading according to the genetic databases, including TamiFlu Resistant and epitope variant strains. The lead US public health agency reports again this week an instance of a low reactor against the antisera. Additionally, silent spread may be expected due to the wide geography of consistent SNP genetics. The present stock explanation of spontaneous random "mutation" will soon be replaced with more rigourous descriptions based on patterns found in factual data.

The epidemiology of this virus did not suddenly change, just the perception. The only thing that has changed in the last few days is that the leading public health agencies have allowed public reporting of the 225G revision. This particular popular 225G with commensurate background of 206T has been in active circulation since May after emerging in April, vectored from both New York and Georgia, and is on record with documented fatal cases since July.

Nothing new there.

Why are the offical public health agencies raising awareness only now? While we do applaud the release of information and the present focus on matching clinicals to the sequences, we also caution against obverse speculation. A primary topic of concern is Cytokinic Dysregulation. Reliance on inspecific terms like "Cytokine Storm" in the media will only continue to misinform the public on a process that is far less understood than the lead investigators would like to admit.

All of which returns us to the basic categories:

What we do know?
What we don't know?

What we do know?

Now that matched clinical data is available, however limited, a potential correlation is being drawn on lung tropism. The standing bench studies, including the Palese and JKT team collaboration in 2006, detailing variant tropism based on differential HA reception at α2-3 and α2-6-linked sialic acids evaluated correlative to protein 225 lend evidence to the concept of deep lung involvement though the experiments were conducted by varying permutations of proteins 190 and 225 on 1918 variants. Whereas, we stand in 2009 with quite different genetics that require cross-validation prior to citation with applicability to PF11.

Tissue type targets are compelling studies and this particular superarray protocol may prove even more useful on PF11 than 1918 samples. We note that though 1918 and PF11 now share 190D and 225G, that all 1918 public sequences show 206S. 206T continues to emerge and conserve regionally in PF11. All 225G bearing strains after April show 206T, except the July CatNS1706 and the undated Vladivostok01.

Reproducing the glycan microarray procedure with the contemporary and ideal dataset including Brasil and Catalonia may bring a tigher focus onto today's issues. We couldn't ask for a more balanced set of control factors with Catalonia offering sequences less than one week apart demonstrating both important pairings: 206S/225G and 206T/225G . . . a bench review made to order.

We also do know that a proper immune response, that is a timely and regulated innate immune response, is not occurring in certain of these patients. When the n +1 generations of the virus progeny begin to lyse the host cells, that failure of innate immune function to have responded early leads to an undetected and massive viral load due to the rapid replication trait of PF11. The cell detritus and the density of moving viral particles elicit a host-driven, limited “self-destruct” series of events because the multiple levels of early detection parameters have been bypassed leaving the core essentially defenseless.

What we don’t know?

Though Cytokinic Dysregulation is occurring in most cases at some level of interchange, the 225G and 225E strains may potentially interfere at a more profound level with the early innate response by amplifying the PF11 conserved effect of the NS1 paired Glutamates at aa96 & 97 that suppresses the IFN synthesis instantiation cycle. Influenza bench researchers don’t know exactly where the failure is occurring or at which combination of cell-to-cell signalers in PF11 or the PF11 225G strains. Until those identification studies are designed, undertaken and reproduced, discussion at this point is stark hypothesis based frequently on the speaker’s sheer lack of present research content mastery. Apparently, saying “I don’t know?” and then returning to the bench to design and gather a proper foundation of data is a skill rarely encouraged in our “Science for Hire” era.

Our team is unimpressed that the wider science community, with such broad analytical skills and exceptional equipment, relies on pseudo-explanation, this cloud of diversion, by invoking the “Cytokine Storm” phrase. More than 20 well-characterised and 100 identified distinct molecular signal functions are at work in the early immune response, including cytokines, but not limited to that class of communicators. Tagging a term for PR purposes is much simpler than tagging a molecule for tracking, but you received your instruments because you can think, not for your ability to improvise inventive talk.

Think.

Eighty billion dollars in research should arrive at a better answer with higher specificity and actionability than the blanket “Cytokine Storm” tome. Data and procedure discover Facts. Anything less is purely Public Relations.

Our team continues to hold an opinion that we first described in 2006 concerning Cytokinic Dysregulation and the NS1 protein of Influenza. Succinctly, the viral ability to suspend innate immunity for up to two days post-infection, as characterised by Mount Sinai this year, prevents the early and required pro-inflammatory Cytokinic Response to viral detection. That blunting, taken in conjunction with detailed studies around adaptive immunity, may result not only in failure to clear the virus from some patients in a timely fashion, but also in failure to produce a useful quantity and competence of memory T-cells and Ab. The early failure to clear a rapidly replicating virus like H5N1 or PF11 results in a frank trauma to the immune system when the first generations of viral progeny lyse their host cells after being undetected and flood the tissues with virii and toxic cell detritus. That disorderly surge of human and viral proteins en masse activates a late and cascading pro-inflammatory response that frequently fails to down-regulate properly.

This explanation is contrary to "pop" science reports that a normal and robust immune response over-generates cytokines and attacks self indiscriminately. We hold that, by the time the virus has lysed thousands of cells and released millions of virii, that most adjacent tissue areas are "fair game" for immune response due to toxic cell detritus and viral travel. That flooding of antigen and waste matter, widespread and instantaneous to the immune system, may further interact with some virally induced derangement of the alternative pathway of complement and generate the intensive up-regulation of signaling, pro-inflammation cascades and the resultant tissue damage described in the clinicals as DIC, DAH and ARDS.

Ergo, the findings of massive tissue damage on necropsy is the result of a failed early innate immune response, not a normal robust response. A normal, properly up- and down-regulated robust innate response clears infection in more than 90% of various infections (viral, fungal and bacterial) and proceeds to generate Ab in short order via the adaptive arm of immunity.

When viral hosting cells properly detect intrusion, flag themselves for apoptosis (cell death) and are then assisted by cytotoxic T-cells, the injection of fragmentins via perforin "tubes" induces an endogenous apoptotic program literally cutting DNA into 200 base multimers (fragments) and eventually condensing chromatin. That organised molecular result is far less inflammatory and far more useful for antigen identification than the disorderly outcome of a virally "exploded" cell. Now you can see why proper genetic expression during each phase of this programmed cell death guarantees a lower pathology than the chaotic and toxic outcome of lytic host cell destruction resulting from viral NS1-induced, delayed genetic expression.

A confluence of PF11 traits (failed early detection, multi-tropism and rapid replication) against the host-pathogen interface may force a limited "self-destruct" in the host upon eventual detection in an attempt to save the organism. That limited "self-destruct" is not the desired outcome of a normal and robust immune response, but occurs due to a failure of the immune system to detect and respond early in the process.

Timing matters.

Individual viral genetics and individual host immune genetic expression are primary effectors that must no longer be discounted under the clouds of some nebulous "Cytokine Storm" or Mysterious Mutation.

May we see the sequences paired with the clinicals?

A flow of virus variants of the

Yesterday morning, the WHO Representative Office in China Chen Weiyun press officer confirmed to reporters over the mainland of China is indeed a case of a current mutation of the virus.

According to Hong Kong media reported that according to the World Health Organization, Brazil, China, Japan, Mexico, Ukraine and the United States have found that mutation of the virus.

Chen Weiyun told reporters this year, Liu Qiyue copies of the mainland of China has appeared 23 variants of influenza A H1N1 influenza virus in cases of the virus and the virus has recently appeared the same as in Norway, but she did not disclose further details.

Chen Weiyun said experts are still doing further research and analysis, but so far the virus does not produce a flow of vaccine resistant, so that the World Health Organization do not intend to release a new proposal or change the previous recommendations.

■ Expert Interpretation

Virus mutates, "depth" into the lungs

PLA Influenza A H1N1 influenza joint prevention and control checks on members of the Group, the Air Force General Hospital, Infection Control Branch, director of Cao Jingui said: "The virus mutates, meaning that deep into the lungs, 'depth' denote two directions, one is to the development of lower respiratory tract, and the second to lung alveolar development. "

Cao Jingui director, said: "If you suffer from a flow of viral pneumonia, its greatest impact is the respiratory system, respiratory function declined, making the body's oxygen partial pressure, blood oxygen partial pressure was reduced, that is in the process of respiration , the effective partial pressure of oxygen absorbed by the drop. "

When inhaled, the decline in the effective partial pressure of oxygen when a direct impact on every major organ in the body, especially when the function of internal organs to fall, and even failure can cause the various functions.
