Augusta College is utilizing a novel dialysis filter to take out parts of a harmful inflammatory response in COVID-19 sufferers in hopes of retaining them from going into organ failure.
Dr. Azeem Mohammed heard a couple of totally different sort of dialysis filter a few years in the past from worldwide colleagues nevertheless it wasn’t till he noticed the devastating inflammatory response provoked by COVID-19 that it grew to become pressing for him to attempt it.
Mohammed, an assistant professor in nephrology and fellow assistant professor Sandeep Padala, at the moment are utilizing the same filter to deal with COVID-19 sufferers within the Intensive Care Unit to attempt to forestall them from growing the overwhelming immune response that may result in multi-system organ failure.
The 2 helped to push AU Well being System’s provider, Baxter Worldwide Inc., to hunt and obtain Emergency Use Authorization from the Meals and Drug Administration to make use of its Oxiris filter on ICU sufferers with COVID-19 who’re in or in peril of going into respiratory failure.
The extreme acute respiratory syndrome coronavirus 2 or SARS CoV2 that causes COVID-19 normally assaults the lungs first and creates injury there earlier than triggering an immune response, Padala stated. The issue turns into when that immune response begins to feed on itself, triggering a fair larger inflammatory response that begins to overwhelm the physique in what is named a “cytokine storm,” he stated. These sufferers are sometimes having bother respiration and as their oxygen stage drops, that lack of oxygen can immediately hurt the kidneys, that are additionally being hit by dangerous results of the inflammatory response, Padala stated.
The virus assaults cells by the angiotensin-converting enzyme 2 receptor discovered generally within the lungs but additionally within the kidneys, the center and the digestive system so “this cytokine storm burst can be affecting the opposite organs” in addition to direct results from the virus, he stated.
The share of sufferers that develop acute kidney damage throughout COVID-19 varies broadly, with Baxter citing a research that discovered it in 15-30% of severely unwell sufferers. Sufferers can then start to develop multisystem organ failure in addition to septic shock and the medication given to assist assist blood stress can even injury the kidneys, Padala stated.
“If we will forestall or cease this cytokine storm, we will forestall the downward spiral of the entire organ injury,” he stated.
He and Mohammed started speaking a couple of month in the past about methods they may intervene, and Mohammed recalled listening to at a global convention a couple of dialysis filter being utilized in Europe that might filter out pro-inflammatory cytokines and different poisonous merchandise. After they contacted Baxter, the corporate stated they’d one thing related, he stated.
“The one caveat being it isn’t FDA-approved,” Mohammed stated. About two weeks in the past, that emergency use approval got here by and AU Well being grew to become one of many first within the nation to start utilizing it. Their preliminary goal can be these ICU sufferers on the point of respiratory failure who would then want a ventilator, Mohammed stated.

“These are the sufferers that we wish to go after, earlier than they’ve organ dysfunction,” he stated. However in concept it might additionally assist these already on a ventilator, Mohammed stated.
“The belief can be the cytokine stage in that affected person would already be very excessive however you continue to would see a lower with this filter,” he stated. Decreasing the pro-inflammatory cells ought to assist the physique recuperate its skill to battle the virus extra efficiently, Mohammed stated.
“The immune response goes haywire,” he stated. “We would like a sure stage of immune response however not overwhelmingly excessive to trigger organ failure. Our assumption is that the additional alongside you’re in your COVID an infection, the immune response it elicits will likely be much less and fewer and fewer. We wish to assist and type of streamline your immune response.”
By eradicating a variety of these inflammatory components, then “the physique ought to be therapeutic,” Padala stated.
The filter is also used together with another anti-inflammatory therapies, such because the drug tocilizumab that targets a selected inflammatory issue known as interleukin-6, which AU Well being is already utilizing to deal with some COVID-19 sufferers.
“The belief is it can lower IL-6 ranges by itself and it is going to be helped alongside additional in its motion by this filter,” Mohammed stated.
