A journalist’s bout with Covid-19

Azrul Affandi Sobry, a journalist struck as he was on the line of duty covering the recent state election in Sabah admits that it wasn't entirely unexpected as the nature of the job entails jostling with others in order to land the story and also confesses that he could have done more to prevent it from happening.

Landing stories – and then some: A journalist’s bout with Covid-19

The pandemic has seen unprecedented global efforts to discover a safe and effective treatment, either by developing new medicines to target the novel coronavirus or repurposing existing drugs.

But very few of the drugs tested and administered so far have proven effective, a conclusion reinforced by a major WHO-backed study released on Friday.

Dexamethasone

The only treatment proven to reduce coronavirus mortality, the steroid dexamethasome has shown promise in early trials among hospitalised patients requiring oxygen.

It has been endorsed as a Covid-19 treatment by both the World Health Organization (WHO) and the European Medicines Agency.

But it remains something of a drug of last resort – early evidence suggests it is only effective among the most serious cases.

More recent research has suggested that other steroids may also play a role in reducing mortality among patients requiring hospital care.

Remdesivir

An antiviral originally developed to treat Ebola, remdesivir was found to reduce the length of hospital stays for coronavirus sufferers from 15 to 11 days on average, according to a study published in May in the New England Journal of Medicine.

However, a pre-print by WHO on Friday found the drug “appeared to have little or no effect” on coronavirus mortality or the length of hospitalisation among more than 11,000 hospitalised patients across 30 countries.

The data has yet to be peer-reviewed in a scientific journal, and appeared to contradict earlier US studies.

Hydroxychloroquine

Perhaps the most controversial drug to emerge from the pandemic, hydroxychloroquine is an anti-malarial hailed as a miracle cure by its proponents.

Critics in contrast warn that due to potential serious side effects, treating coronavirus patients with hydroxychloroquine is even worse than a placebo.

While high-profile figures such as US President Donald Trump appear convinced, the science says otherwise.

In June the British-led Recovery trial team said that hydroxychloroquine does nothing to reduce coronavirus mortality, something corroborated by the WHO’s study results on Friday.

Lopinavir-ritonavir

Used against HIV, the virus that causes AIDS, this one-two anti-viral punch has shown to be ineffective at treating Covid-19 in hospital settings.

Antibodies

When the body fights off viruses such as SARS-CoV-2 it develops antibodies – proteins that are programmed to target specific pathogens.

These anti-bodies can be synthesised in a lab and could in theory be given to patients sick with Covid-19 to boost their own natural immune response.

Trump received this still experimental treatment when he was hospitalised with the virus.

Again, however, WHO on Friday said the technology, developed by US biotech firm Regeneron, showed little or no benefit among hospitalised coronavirus patients.

Plasma

Plasma taken from the blood of recovered patients showed some early promise when given intravenously to people sick with Covid-19.

It has already shown to help speed recovery from Ebola and SARS, which is caused by the same family of pathogens as the novel coronavirus.

Recovery has an ongoing clinical trial for plasma treatment.

Others

The British-led survey is also currently evaluating the efficacy of tocilizumab, an immunosuppressant scientists hope will be able to prevent excess and potentially lethal inflammation in serious cases.

And a number of trials are underway exploring the repurposing of various drugs that are used to treat other illnesses.
