Death by Swine Flu

I wonder...now that they know this, is there a way to break the inflammatory cycle and prevent a "routine" H1N1 case from developing ARDS? RTC anti-inflammatories? I dunno, but I wish they would come up with some kind of home-care that is effective in preventing this complication, because it seems pretty random on who gets a mild 2-3 day illness and who ends up dead. Add to that the fact that clinics, EDs and PCPs in my area are swamped and basically refusing patients with only mild symptoms and no chronic conditions, and you have cases like the 8th grader who died this week.

I sent a 1st grader home yesterday with flu like symptoms. He has severe asthma and has already been hospitalized once this year and once last year for pneumonia. His mom took his straight to the ED at the children's hospital and waited until 1AM, when she finally gave up and went home. His PCP is squeezing him in today. I am glad he made it through the night. I am scared for my kiddos and staff at this point. We have 10% of the student population absent, most of which have flu like illness.

I meant to get back to you about those masks, janfrn. The IOM came out with guidance recently that said the N95 should be fit tested, as you may have heard.

I would say to that, good guidance, but the study it was based on in Beijing, China clearly said that it did not seem to matter whether or not the masks were fit tested or not, just as long as it was an N95, they were 75% more efficacious than the surgical mask. You could listen to the actual testimony of Dr. Raina McIntyre at the IOM open hearings on this if you have the time as it is archived. It stayed in my mind because of you.

I only bring this up because you mentioned in a prior post your concern about the poor fit. It is better to have a good fit, but because of that study, I am not as personally concerned for myself though I am very careful with these patients when they are actively coughing. Actually, I worry more about people that do not know that they are infected, are not masked, but are coughing, like the folks on the airplanes that I traveled on last week to the CIDRAP Conference.

We are all gaining lots of experience in PPE right now, even on my psych unit as these patients begin to show s/s after they are admitted to our floor. We have to put on our gear in the nurse's station, and troop down the hall in full PPE to the patient's room.

We are so not prepared to deal with this on this type of unit...

I am sorry that your little one is sick right now. I hope that he recovers quickly.

I think that starting anti-inflammatories would be a very good idea for a certain subset of kids known to have had to use them in the past. Parents should be having a discussion with the docs, and maybe with the school nurse about this now in advance of the kids getting sick. Being pro-active, and having a plan is smart given how busy these docs are going to be very soon.

I say this only because I am an asthmatic, and have had to use the prednisone dose packs myself. I know when I need it. A sick colleague put herself on prednisone recently. She was a probable swine flu case (exposed to cousin on Tamiflu), and very ill when she called off work. I saw how sick she was when she left work, and I do believe that starting the prednisone for her was a very wise idea. She is an immune suppressed asthmatic with several other health problems as well. She did, of course, contact her doc about what she was doing as well.

As for the otherwise perfectly healthy kids that start getting very sick, I am stumped there. How do we protect them? It is not happening from hand washing. The science simply does not support handwashing as a method of preventing swine flu. This was a point hammered home at the CIDRAP Conference. Handwashing is important for other reasons, but it will not prevent kids from getting swine flu at school.

I cannot help but admit that some of these fatal cases particularly in children have really shaken me...The very last point that Dr. Osterholm made at the CIDRAP Conference was that many would not take this pandemic seriously until the numbers of dead children became too many to be ignored. As I read some of the comments on some of these threads here at allnurses, I have to agree. Until the personal tragedy of these families actually hits them in the face, many will trivialize what is happening.

I saw very sad thing on TV news yesterday. A grief stricken man talking about his dead 14 year old daughter. Child had no health problems. It was 4 days from onset of infection to death. They apparently were getting ready to put her on ECMO when she arrested. HE said, "my little girl was radiant". Then he cried. Just rips your heart out.

Researcher Identifies New Target To Prevent Fatal Flu Lung Complication

Research led by Dr. Jay Kolls, Professor and Chairman of Genetics at LSU Health Sciences Center New Orleans, has identified a therapeutic target for acute lung injury resulting in acute respiratory distress syndrome, a highly fatal complication of influenza infection. The research, which will be published in The Journal of Immunology in October, is currently available in the Next in the JI section online at http://0-www.jimmunol.org.innopac.lsuhsc.edu/cgi/reprint/jimmunol.0900995v1.

Interleukin-17 (IL-17), an immune system cell involved in proinflammatory response, is a potent regulator of neutrophils (white blood cells). Following infection, IL-17 uses a signaling receptor called IL-17RA to direct large numbers of neutrophils to the infection. Neutrophils play a key role in the development of acute lung injury because they rapidly infiltrate the lung and are an important source of cytokines (immunomodulating agents), a byproduct of which is swelling, fluid in the lungs, and low levels of oxygen in the blood.

The research team wanted to determine whether blocking IL-17RA signaling would protect against acute lung injury following influenza infection. Using an influenza model in control and knockout mice (genetically engineered without IL-17RA), they worked to identify a pathway to control the function of IL-17RA and the migration and action of neutrophils. They found decreased levels of illness and death among the IL-17RA knockout mice, despite a higher viral load. The researchers found that the knockout mice had fewer neutrophils in the lung, thus lower levels of inflammation and less lung injury. Comparing their results to studies of IL-17RA knockout mice in other models of viral infection, the researchers conclude that therapeutic regulation of IL-17 signaling may be beneficial not only in acute lung injury, but also in treating viral infections of other organs.

"Each year, more than 200,000 people are hospitalized with flu-related complications in the United States," notes Dr. Kolls. "A number of those who have died from H1N1 flu this year have had lung damage different than we typically see with seasonal flu. These cases have been marked by deep lung infections with diffuse damage to the alveoli - the structures that deliver oxygen to the blood. Advancing our findings has the potential to benefit both."

The research was supported by a grant from the National Heart, Lung, and Blood Institute of the National Institutes of Health.

Thanks for the further info on mask fittings, Indigo. I chuckled at your comment about my little one... who is 26, severely handicapped and developmentally delayed. He's also a transplant recipient. So I have big concerns for him. He attends a day program for severely handicapped/medically fragile adults and many of them have been sick in the recent past. The facility has a pandemic plan in place and will send clients home if the on-site nurse feels their symptoms are suggestive, so I'm thankful for that. I'm sure tempted at this point to put him on low-dose prednisone but he has such terrible side effects from it that it would be a last resort.

Not a little kid, but still your baby.

What does his doc say about using the low dose prednisone with his heatlh challenges? Not my area of expertise at all...
