Alarmed as COVID patients’ blood thickened, New York doctors try new treatments

NEW YORK (Reuters) – Because the novel coronavirus unfold by way of New York Metropolis in late March, docs at Mount Sinai Hospital observed one thing unusual occurring to sufferers’ blood.

Indicators of blood thickening and clotting have been being detected in numerous organs by docs from totally different specialties. This might grow to be one of many alarming methods the virus ravages the physique, as docs there and elsewhere have been beginning to notice.

At Mount Sinai, nephrologists observed kidney dialysis catheters getting plugged with clots. Pulmonologists monitoring COVID-19 sufferers on mechanical ventilators may see parts of lungs have been oddly cold. Neurosurgeons confronted a surge of their normal caseload of strokes because of blood clots, the age of victims skewing youthful, with at the very least half testing optimistic for the virus.

“It’s very putting how a lot this illness causes clots to type,” Dr. J Mocco, a Mount Sinai neurosurgeon, mentioned in an interview, describing how some docs suppose COVID-19, the sickness attributable to the coronavirus, is greater than a lung illness. In some circumstances, Mocco mentioned, a stroke was a younger affected person’s first symptom of COVID-19.

As colleagues from varied specialties pooled their observations, they developed a brand new therapy protocol. Sufferers now obtain excessive doses of a blood-thinning drug even earlier than any proof of clotting seems.

“Possibly, simply possibly, if you happen to stop the clotting, you may make the illness much less extreme,” mentioned Dr. David Reich, the hospital president. The brand new protocol is not going to be used on sure high-risk sufferers as a result of blood thinners can result in bleeding within the mind and different organs.

“FUNNY YOU MENTIONED THAT”

Within the three weeks starting mid-March, Mocco noticed 32 stroke sufferers with massive blood blockages within the mind, double the standard quantity for that interval.

5 have been unusually younger, below age 49, with no apparent threat components for strokes, “which is loopy,” he mentioned. “Very, very atypical.” The youngest was solely 31.

A minimum of half of the 32 sufferers would take a look at optimistic for COVID-19, Mocco mentioned.

In the meantime, Dr. Hooman Poor, a Mount Sinai lung specialist, discovered himself working a late shift with 14 sufferers on ventilators. The ventilator readings weren’t what he anticipated.

The lungs didn’t appear stiff, as is widespread in pneumonia. As a substitute, it appeared blood was not circulating freely by way of the lungs to be aerated with every breath.

Poor ran right into a kidney physician that evening, who remarked that dialysis catheters have been typically getting blocked with clots.

“And I mentioned, ‘It’s humorous that you simply talked about that as a result of I really feel like all these sufferers have blood clots of their lungs,’” Poor recalled.

Reich, the hospital president, instructed Poor in regards to the surge in strokes seen by Mocco and mentioned the 2 docs ought to staff up, setting off days of discussions and conferences with the hospital’s division heads.

At 2:46 a.m. on Easter Sunday, Poor despatched Mocco his first draft of what would turn into the brand new therapy protocol.

DOCTORS SHARE FINDINGS  

As their wards started to overflow with COVID-19 sufferers, the Mount Sinai docs learn papers describing comparable findings from docs in China’s Hubei province and different hard-hit areas, and mentioned them with their friends in telephone calls and webinars.

Mocco known as neurosurgeons he is aware of elsewhere within the nation. At Philadelphia’s Thomas Jefferson College Hospital, Dr. Pascal Jabbour had begun to see an identical surge in strokes amongst folks with COVID-19. The best way his sufferers’ blood congealed reminded him of congenital situations similar to lupus, or sure cancers.

“I’ve by no means seen every other viruses inflicting that,” Jabbour mentioned.

In Boston, the Beth Israel Deaconess Medical Heart started a medical trial earlier this month to see if tPA, an anti-clotting drug, may assist severely sick COVID-19 sufferers.

Clotting can develop in anybody who will get very sick and spends lengthy intervals of time motionless on a ventilator, however docs say the issue appeared to point out up sooner in COVID-19 sufferers as a extra direct consequence of the virus.

At Mount Sinai, sufferers in intensive care typically obtain the blood-thinning agent heparin in weaker prophylactic doses. Underneath the brand new protocol, greater doses of heparin usually used to dissolve clots can be given to sufferers earlier than any clots are detected.

The therapy joins a rising toolbox on the hospital, the place some sufferers are receiving the antibody-rich plasma of recovered COVID-19 sufferers or experimental antiviral medicine.

The American Society of Hematology, which has additionally famous the clotting, says in its steerage to physicians that the advantages of the blood-thinning remedy for COVID-19 sufferers not already displaying indicators of clotting are “at present unknown.”

“I definitely wouldn’t anticipate harps to play and angels to sing and other people to only rip out their intravenous strains and waltz out of the hospital,” mentioned Reich. “It’s probably going to be one thing the place it simply moderates the extent of the illness.”
