Tamiflu Resistant Pandemic H1N1 Cases in Texas

Recombinomics Commentary 03:14
August 4, 2009

"We have found resistance to Tamiflu on the border. We have observed some cases, few to be sure, in El Paso and close to McAllen, Texas," said Maria Teresa Cerqueira, head of the local PAHO office.

Cerquiera said one patient diagnosed with a Tamiflu-resistant strain had been treated with Zanamivir -- an anti-viral made by GlaxoSmithKline -- and another was given no alternative medication. Both survived.

The above comments describe at least two oseltamivir resistant patients along the Texas / Mexico border. The cases are at opposite ends of the border (see map) and raise concerns that the resistance developed in the absence of Tamiflu treatment. One patient had "diagnosed" resistance and was treated with Zanamivir, while the other wasn't treated with Zanamivir, leaving open the possibility that neither were treated with oseltamivir. Moreover, the wording left open the possibility that there were more than two patients, suggesting fit swine H1N1 with H274Y was circulating over a wide area.

The emergence of fit swine H1N1 with H274Y is not a surprise. A case has already been reported in <a rel="nofollow" href="http://www.recombinomics.com/News/07070901/H274Y_HK_Seq.html">Hong Kong</a> in a traveler from San Francisco. The precursor for this strain has been reported <a rel="nofollow" href="http://www.recombinomics.com/News/07100901/H274Y_Fit.html">worldwide</a>, although the only case reported in the US was in April in New Jersey, raising concerns that the fit strain was circulating silently, in part because the cases were mild and not being tested. The patient in Hong Kong, like one of the patients recovered without treatment with Relenza, indicating the cases were relatively mild.

The fact that these cases were reported simultaneously also raises concerns that a fit H274Y is circulating in the area.

Details on the number of cases, and release of sequences, would be useful.

I will repeat what the medical autorithy says up here in Quebec;

Before this case we found only 4 resistant on probably 1 millions cases

Several patients were found to be resistant to antiviral near the border. "This is not a surprise, there was no worry," says Roche, which estimated that 0.5&#37; rate of resistance.


Boxes of Tamiflu (Sipa)
Cases of resistance to Tamiflu, the main antiviral drug used against influenza A (H1N1), were found near the border between the United States and Mexico, said Monday 3 August the Pan American Health Organization (PAHO). "We found cases of Tamiflu resistance to the border. We have seen some cases, few of which we are confident, El Paso and around McAllen, Texas," said Dr. Maria Teresa Cerqueira, responsible local office of PAHO, at a conference on influenza A. The persons concerned cross the border regularly and were autom&#233;dicament&#233;es, says the doctor.


Cases "isolated"
"In the U.S., Tamiflu is a prescription but it is widely available in Mexico and Canada and took the first sneeze. And when it is really useful, it does not work anymore", said Maria Teresa Cerqueira. She explained that a patient with a strain of influenza A (H1N1) viruses resistant to Tamiflu has been treated positively to Zanamivir, another antiviral drug, and another patient received no other treatment. Both patients survived, she argued.
In July, a case of resistance to Tamiflu had been found in Canada. It was the first case in North America, according to Dr. Guy Boivin, Center hospitalier de l'Universit&#233; Laval (CHUL) in Quebec, who had discovered this resistant strain. Cases of resistance to antiviral therapy were also recorded in Denmark, Japan and Hong Kong.
The World Health Organization (WHO) has estimated that these cases are "isolated" and that it maintains its recommendation for Tamiflu and Relenza.


"There is no worry for the moment"
The laboratory Roche, Tamiflu seller, said he expected at 0.5% of its antiviral resistance from the results of clinical trials.
"This is not a surprise," says the director of the pharmaceutical division of Roche, William Burns: "in the case of the flu season, about 0.4% of the organisms may be resistant. There not worried at the moment. " "We do not increase in these cases of resistance," adds the CEO of Roche Severin Schwan.
"It is not excluded that in a community where people are treated with Tamiflu, there are few cases of viruses that develop resistance and spread," explains Dr. Thierry Buclin, a medical assistant in the office clinical pharmacology and toxicology at the CHUV of Lausanne. "The real question is: who should take Tamiflu?" Dr. Buclin nuance. "What you win to deal with Tamiflu, if one can be cured with paracetamol?" Hits there.

This version of the AFP story suggest that resistance might have been linked to self-prescribed tamiflu. However, it doesn't state that it was, and also does state that the resistance was discovered because the patients received Tamiflu treatment from a doctor. Thus, the number of patients and details surrounding the "diagnosis" remain murky.

Spread of Tamiflu Resistant Pandemic H1N1 in Texas
Recombinomics Commentary 13:46
August 4, 2009

We have seen some cases, few of which we are confident, El Paso and around McAllen, Texas," said Dr. Maria Teresa Cerqueira, responsible local office of PAHO, at a conference on influenza A. The persons concerned cross the border regularly and were autom&#233;dicament&#233;es, says the doctor.

The above translation adds to the uncertainty associated with the oseltamivir resistance report on the Texas / Mexico border (see map). Since the report cites self-treatment of Tamiflu, it is unclear if and when the resistant cases were treated. In previously announced cases worldwide, five were on prophylactic treatment because of exposure , and at least two developed symptoms on the fifth day of Tamiflu treatment, raising concerns that H274Y was present at reduced levels in these patients and the treatment allowed for the detection of the H274Y, which may be the case for some of the patients on the Texas border.

However a traveler from San Francisco was tested in Hong Kong and had H274Y in the absence of Tamiflu treatment, which may also be the case for some of the patients along the Texas border. More aggressive testing and release of these sequences would be useful.

However, these sequences should be tested more thoroughly for the presence of H274Y as a mixture. A recent report on Relenza resistance (Q136K) indicated the polymorphism was only detected after culture on MDCK cells, indicating the levels in the clinical sample were below detection. In addition to the nine examples in southeast Asia / Australia, which were in the report, a sequence from Nicaragua has been published (see list here) and a mixture from Pennsylvania was published a year ago, although agency reports claim no Relenza resistance in the US in the 2007/2008 season. The Q136K was in patients who were not being treated with Relenza, and more widespread treatment of swine flu patients will likely lead to more detected cases, which is the likely situation for H274Y also.

The failure to provide more concrete information and sequences from the resistant patients along the Texas border increases concerns that resistant pandemic H1N1 is widespread, but grossly under-represented in the limited number of public sequences released at Genbank or GISAID.

PB1 E627K. It was in the original and first clone from Shanghai, but was absent in the second clone. This is another important change which may be flying below the radar, especially at this time in the northern hemisphere.

In the fall, the story will be quite different.

Re: Tamiflu-resistant swine flu found on US-Mexico border

Dr. Niman,

Do you have any sort of rough outline as to what you think will happen in the fall and when things will start to become noticeable as far as severe sickness/death?

Should that have been in the Sao Paolo thread, and do you have any information on what significance G1761A might have?

Re: Tamiflu-resistant swine flu found on US-Mexico border

It just provides more evidence that these changes were due to recombination. There now are three polymorphisms from the Canadian swine that are in the same sequences from Argentina.

Re: Tamiflu-resistant swine flu found on US-Mexico border

Dr. Niman,

Do you have any sort of rough outline as to what you think will happen in the fall and when things will start to become noticeable as far as severe sickness/death?

Gennie

The CDC has said they expect outbreaks like NYC to be widespread in the US in the fall. I think this is an optimistic projection. In the northern hemisphere the fall will signal the start of flu season and cases increase simply because the cooler temperature allows the virus to remain viable longer. Thus there is more transmission just because there is more virus laying around.

However, the species jump is significant, and major changes are possible with minor changes. I expect H274Y to be widespread as well as PB2 E627K. These two changes alone could have a significant impact because the virus will be able to grow faster at lower temperatures and will be resistant to Tamiflu (and Relenza resistance may follow).

Some signals will come out of sequences from the southern hemisphere, although those sequences lag. There is at least one marker for Argentina, and the Sao Paulo change may be significant. There may be more sequences released this week, which could make these initial onservations on fatal cases easier to evaluate.

In addition, there are more people living in the northern hemisphere, so issues in the southern hemisphere could be magnified in the north. I suspect some time in September the picture will be clearer and I expect results to indicate that the CDC projection is VERY optimistic.

Health workers were on Tuesday warned against overprescribing a drug used to treat swineflu, called Tamiflu, as the illness could become drug-resistant.

This is according to Dr Chuma Makunga, from the National Institute of Communicable Diseases, who was speaking at a Pharmacy Conference at Sun City.

She said there were already four countries, identified by the World Health Organisation, in which some strains of swineflu were resistant to Tamiflu.

"It is not to be given to everyone," she told conference delegates.

"It is up to individual clinicians to read the information that is sent to them and to ensure they know what they were doing."

She added that doctors were informed of how the drug should be prescribed.

South Africa's first fatality from the H1N1 virus, in the Western Cape, was reported on Monday.

The government was no longer trying to contain the virus but working to ensure its pandemic protocols were in place, Makunga said.

"What we are doing is collecting information about the virus so that we know as much as we can about the way it works."

Pregnant women were a risk group for complications due to swineflu and the illness seems to affect mostly young people, up to the age of 49, while the elderly appeared to be showing some immunity to it, the conference heard. - Sapa

Let me reiterate something from my conversation with our daughter's pulmonary doctor yesterday. He first thought we would get by until roughly December (referring to Houston specifically) before we experienced a severe outbreak. After seeing how many cases the hospital has had this summer (10,000% more flu than normal in the summer) he expects a bad flu season beginning essentially this month when the kids return to school.

Homeland Secretary Napolitano predicts severe flu epidemic for fall

By Steve Sternberg, USA TODAY
U.S. Secretary of Homeland Security Janet Napolitano asserted Tuesday that pandemic flu is likely to flare up soon after schools open in the fall, well before any vaccine is available.

Napolitano also acknowledged that there would not be enough pandemic flu vaccine for everyone, at least in the early stages of the flu season. "There will be prioritization of vaccinations," she told members of the USA TODAY editorial board.

The flu strain causing the pandemic, a new strain of H1N1 flu that is also known as swine flu, is especially dangerous because it is genetically different from virtually every other known flu virus. As a result, most people are defenseless against it ? making vaccine the keystone of any effort to prevent illness and save lives.

Napolitano said the flu epidemic is likely to be severe, but not as severe as the 1918 pandemic, the world's worst. In 1918, flu killed at least 675,000 people in the USA and up to 50 million worldwide. She said it's more likely that the pandemic would mirror 1957, when flu killed about 70,000 people in the USA and more than one million people worldwide, according to the Centers for Disease Control and Prevention.
