Dexamethasone

Many docs, together with these in the US, have been treating very ailing COVID-19 sufferers with corticosteroids for the reason that pandemic started. It makes biological sense for these sufferers who’ve developed a hyper-immune response (a cytokine storm) to the viral infection. In these instances, it’s the immune system’s overreaction that’s damaging the lungs and different organs, and too usually resulting in demise.

Dexamethasone and different corticosteroids (prednisone, methylprednisolone) are potent anti-inflammatory medicine. They’re available and cheap.

The NIH COVID-19 therapy pointers suggest the usage of dexamethasone in sure folks hospitalized with extreme COVID-19. The advice was based mostly on outcomes from the recovery trial. Within the examination, greater than 6,000 sufferers hospitalized with COVID-19 randomly acquired both dexamethasone or commonplace therapy. Sufferers who required supplemental oxygen or ventilators and who acquired dexamethasone had been much less more likely to die inside 28 days than those that acquired commonplace care.

Does convalescent plasma assist folks with COVID-19?

When folks get better from COVID-19, their blood accommodates antibodies that their bodies produced to struggle the coronavirus and assist them to get nicely. Antibodies are present in plasma, a part of the blood.

Convalescent plasma — actually plasma from recovered sufferers — has been used for greater than 100 years to deal with a wide range of sicknesses from measles to polio, chickenpox, and SARS. It’s extensively believed to be secure.

In August 2020, the FDA issued an emergency use authorization (EUA) for convalescent plasma in sufferers hospitalized with COVID-19.

A small however well-designed trial (randomized, double-blind, and placebo-controlled) was revealed within the New England Journal of Medication in January 2021. The examination solely enrolled sufferers 65 and older, and researchers screened the convalescent plasma to make sure it contained excessive ranges of antibodies. The researchers discovered that sufferers who acquired convalescent plasma inside three days of growing signs had been 48% much less more likely to develop extreme COVID sickness, in comparison with sufferers who acquired a placebo.

Nonetheless, a meta-analysis of 4 peer-reviewed and revealed randomized scientific trials, revealed in JAMA (The Journal of the American Medical Association), had much less promising outcomes.

Nevertheless, in an article revealed in December 2020 in JAMA, researchers reported that hydroxychloroquine didn’t lead to any medical advantages for adults hospitalized with respiratory sickness from COVID-19, in contrast with placebo. The NIH remedy pointers advocate in opposition to using hydroxychloroquine for COVID-19, in each hospitalized and non-hospitalized sufferer.

Protection of Ibuprofen to deal with signs of COVID-19

Some French medical doctors advise in opposition to utilizing ibuprofen (Motrin, Advil, many generic variations) for COVID-19 signs primarily based on reviews of in any other case wholesome folks with confirmed COVID-19 who had been taking an NSAID for symptom reduction and developed an extreme sickness, particularly pneumonia. These are solely observations and never primarily based on scientific research.

The WHO initially really helpful utilizing acetaminophen as an alternative to ibuprofen to assist scale back fever and aches and pains associated with this coronavirus infection, however now states that both acetaminophen or ibuprofen can be utilized.

One meta-analysis discovered that individuals who took vitamin D dietary supplements, significantly those that had low vitamin D ranges, had been much less prone to develop acute respiratory tract infections than those that did not.

Vitamin D could defend in opposition to COVID-19 in two methods. First, it could assist enhance our body’s pure protection in opposition to viruses and microorganisms. Second, it could assist stop an exaggerated inflammatory response, which has been proven to contribute to extreme sickness in some folks with COVID-19.

Our bodies make vitamin D when uncovered to sunshine. 5 to 10 minutes of solar publicity on some or most days of the week to the arms, legs, or again without sunscreen will allow you to make sufficient of the vitamin. Good meal sources of vitamin D embrace fatty fish (reminiscent of tuna, mackerel, and salmon), meals fortified with vitamin D (reminiscent of dairy merchandise, soy milk, and cereals), cheese, and egg yolks.

The really helpful dietary dose of vitamin D is 600 IU every day for adults 70 and youthful and 800 IU every day for adults over 70. A day-by-day complement containing 1,000 to 2,000 IU of vitamin D is probably going protected for most individuals. For adults, the danger of dangerous results will increase above 4,000 IU per day.

This will embrace individuals who weren’t initially recognized as having COVID-19 as a result of that they had no signs, had delicate signs, selected to not get examined, had a false-negative check, or couldn’t get examined for any purpose. Serologic assessments will present an extra correct image of how many individuals have been contaminated with, and recovered from, coronavirus, in addition to the true fatality charge.

Serologic assessments may additionally present details about whether or not folks develop into proof against coronavirus as soon as they’ve recovered and, if that’s the case, how long that immunity lasts.
