A 'Mild Attack' of Corona could be Dangerously Misleading

Otherwise healthy people who thought they recovered from coronavirus are reporting persistent and strange symptoms - including strokes writes Adrienne Matei in The Guardian

Conventional wisdom suggests that when a sickness is mild, it’s not too much to worry about. But if you’re taking comfort in World Health Organization reports that over 80% of global Covid-19 cases are mild or asymptomatic, think again. As virologists race to understand the biomechanics of Sars-CoV-2, one thing is becoming increasingly clear: even “mild” cases can be more complicated, dangerous and harder to shake than many first thought.

Throughout the pandemic, a notion has persevered that people who have “mild” cases of Covid-19 and do not require an ICU stay or the use of a ventilator are spared from serious health repercussions. Just last week, Mike Pence, the US vice-president, claimed it’s “a good thing” that nearly half of the new Covid-19 cases surging in 16 states are young Americans, who are at less risk of becoming severely ill than their older counterparts. This kind of rhetoric would lead you to believe that the ordeal of “mildly infected” patients ends within two weeks of becoming ill, at which point they recover and everything goes back to normal.

While that may be the case for some people who get Covid-19, emerging medical research as well as anecdotal evidence from recovery support groups suggest that many survivors of “mild” Covid-19 are not so lucky. They experience lasting side-effects, and doctors are still trying to understand the ramifications.

Some of these side effects can be fatal. According to Dr Christopher Kellner, a professor of neurosurgery at Mount Sinai hospital in New York, “mild” cases of Covid-19 in which the patient was not hospitalized for the virus have been linked to blood clotting and severe strokes in people as young as 30. In May, Keller told Healthline that Mount Sinai had implemented a plan to give anticoagulant drugs to people with Covid-19 to prevent the strokes they were seeing in “younger patients with no or mild symptoms”.

Doctors now know that Covid-19 not only affects the lungs and blood, but kidneys, liver and brain – the latter potentially resulting in chronic fatigue and depression, among other symptoms. Although the virus is not yet old enough for long-term effects on those organs to be well understood, they may manifest regardless of whether a patient ever required hospitalization, hindering their recovery process.

Another troubling phenomenon now coming into focus is that of “long-haul” Covid-19 sufferers – people whose experience of the illness has lasted months. For a Dutch report published earlier this month (an excerpt is translated here) researchers surveyed 1,622 Covid-19 patients with an average age of 53, who reported a number of enduring symptoms, including intense fatigue (88%) persistent shortness of breath (75%) and chest pressure (45%). Ninety-one per cent of the patients weren’t hospitalized, suggesting they suffered these side-effects despite their cases of Covid-19 qualifying as “mild”. While 85% of the surveyed patients considered themselves generally healthy before having Covid-19, only 6% still did so one month or more after getting the virus.

After being diagnosed with Covid-19, 26-year-old Fiona Lowenstein experienced a long, difficult and nonlinear recovery first-hand. Lowenstein became sick on 17 March, and was briefly hospitalized for fever, cough and shortness of breath. Doctors advised she return to the hospital if those symptoms worsened – but something else happened instead. “I experienced this whole slew of new symptoms: sinus pain, sore throat, really severe gastrointestinal issues,” she told me. “I was having diarrhea every time I ate. I lost a lot of weight, which made me weak, a lot of fatigue, headaches, loss of sense of smell …”

By the time she felt mostly better, it was mid-May, although some of her symptoms still routinely re-emerge, she says.

“It’s almost like a blow to your ego to be in your 20s and healthy and active, and get hit with this thing and think you’re going to get better and you’re going to be OK. And then have it really not pan out that way,” says Lowenstein.

Unable to find information about what she was experiencing, and wondering if more people were going through a similarly prolonged recovery, Lowenstein created The Body Politic Slack-channel support group, a forum that now counts more than 5,600 members – most of whom were not hospitalized for their illness, yet have been feeling sick for months after their initial flu-like respiratory symptoms subsided. According to an internal survey within the group, members – the vast majority of whom are under 50 – have experienced symptoms including facial paralysis, seizures, hearing and vision loss, headaches, memory loss, diarrhea, serious weight loss and more.

“To me, and I think most people, the definition of ‘mild’, passed down from the WHO and other authorities, meant any case that didn’t require hospitalization at all, that anyone who wasn’t hospitalized was just going to have a small cold and could take care of it at home,” Hannah Davis, the author of a patient-led survey of Body Politic members, told me. “From my point of view, this has been a really harmful narrative and absolutely has misinformed the public. It both prohibits people from taking relevant information into account when deciding their personal risk levels, and it prevents the long-haulers from getting the help they need.”

At this stage, when medical professionals and the public alike are learning about Covid-19 as the pandemic unfolds, it’s important to keep in mind how little we truly know about this vastly complicated disease – and to listen to the experiences of survivors, especially those whose recoveries have been neither quick nor straightforward.

It may be reassuring to describe the majority of Covid-19 cases as “mild” – but perhaps that term isn’t as accurate as we hoped.

Families face battle with GSK over dangerous diabetes drug


Exclusive: Pharmaceutical giant resists claims despite settlement with victims in US

Thousands of families in the UK could be deprived of compensation for the death or harm of a relative caused by the diabetes drug Avandia, even though the British maker has agreed to pay billions of dollars to settle similar claims in the US.
The licence for Avandia was revoked in Europe, in September 2010, because of evidence that it could cause heart failure and heart attacks. The drug can still be prescribed in the US, but not to patients at risk of heart problems.
A scientist with the Food and Drug Administration estimated that Avandia could have been responsible for 100,000 heart attacks in the US.
The manufacturer, GlaxoSmithKline, has admitted concealing data about the damaging side-effects of the drug, and there is evidence of the drug's harmful effects. But, despite this, GSK is not prepared to settle claims in the UK without a court fight.
The history of drug litigation in the UK suggests that families might not easily get  compensation.
Daniel Slade, with the Express company of solicitors in Manchester, has 19 cases on his books and has begun proceedings against GSK in four of them.
The pharmaceutical firm has told the solicitors that it will contest the cases. In just one of the cases it has indicated a willingness to spend £600,000 on its defence, which, the solicitor says, would be a fraction of what the claim is worth.
"It is very disappointing," said Slade. "We anticipate that these claims do have a good prospect of success, but they still have to prove their case in the UK with suitable evidence. They are tasked with having to produce that evidence, including medical expert opinion. It is a burden one would have thought they might not have to go through."
He expected that, if GSK fought in the courts rather than settled outside, as it had done in the US, it would take years for bereaved relatives, or those who have been harmed, to get any sort of payment.
A spokesman for GSK said: "We have every sympathy for people with complications associated with diabetes and those who care for them, but unfortunately we are unable to comment on individual legal cases. We continue to believe that the company acted appropriately and responsibly in its management of Avandia."
Liz Thomas, policy manager at the patient safety charity Action against Medical Accidents, said it had "become increasingly difficult in the UK to challenge large corporations such as pharmaceutical companies, an incredibly expensive form of litigation".
Corporations have a vast amount of money at their disposal to contest legal cases, butlegal aid is about to cease for medical negligence cases.
The Avandia cases in Manchester will be fought on a "no win, no fee" basis by Express solicitors.
The cases in the US were settled by GSK extremely quickly, said Thomas. "I would hope they would not take advantage [in Britain] of the inequality of arms."
Avandia was first introduced in the NHS in July 2000. It was given to people with type 2 diabetes whose glucose levels were no longer being properly controlled by the standard drugs – metformin and a sulphonylurea drug. Avandia could be prescribed with those drugs or on its own.
The drug, which generically is known as rosiglitazone, was designed to lessen the body's resistance to insulin. It was available as a standalone drug – Avandia – or in a combination with metformin, and known as Avandamet.
When both drugs were withdrawn by the European Medicines Agency, there were about 90,000 people taking them in the UK.
The first warnings of trouble with Avandia came in 2007, when a prominent US scientist, Steve Nissen, published data from a review of 42 clinical trials which had been carried out on the drug. The trials involved 28,000 patients, and showed that Avandia could cause heart attacks. Further trials, the results of which were published in 2010, found people on Avandia were 27% more likely to have a stroke, 25% more likely to have heart failure, and 14% more likely to die, than patients on an alternative diabetes drug.
Potentially yet more damaging for GSK was its guilty plea to federal charges of concealing data about the drug's side effects. Most of the data on the drug comes from GSK's own trials. In November 2011 GSK agreed to pay $3bn to the US government over the Avandia issue and to end investigations into its marketing of the antidepressants Paxil (Seroxat in the UK) and Wellbutrin.
"This is a significant step toward resolving difficult, long-standing matters which do not reflect the company that we are today," Andrew Witty, chief executive of GlaxoSmithKline, said at the time.
GSK is also still defending cases in the UK from people who claim to have been badly affected by Seroxat. A group action, involving people who say they suffered severe withdrawal problems when they tried to stop the drug, has been going on for years though many claims have been settled in the US.
The same is true of Vioxx, made by Merck, the painkiller that was withdrawn after it emerged eight years ago that it doubled the risk of a heart attack.
