A study in Belgium that went through the hospital data of 8,075 patients has found that low doses of hydroxychloroquine (HCQ) was associated with lower mortality in hospitalised patients with Covid-19 diagnosed and treated early or later after onset of symptoms.

The anti-malarial drug HCQ has been largely used and investigated as a therapy of Covid-19 across various settings, at a total dose usually ranging from 2,400 mg to 9,600 mg.

In Belgium, the use of low-dose HCQ (2,400 mg in total over five days) was recommended for hospitalised patients with Covid-19, said the study published in the International Journal of Antimicrobial Agents.

“We conducted a retrospective analysis of in-hospital mortality in the Belgian national Covid-19 hospital surveillance data,” the authors wrote.

Patients treated either with HCQ alone and supportive care (HCQ group) were compared to patients treated with supportive care only (no-HCQ group).

Of 8,075 patients with complete discharge data on May 24 and diagnosed before May 1, 4,542 received HCQ in monotherapy and 3,533 were in the no-HCQ group.

Death was reported in 804 of 4542 (17.7 per cent) and 957 of the 3,533 (27.1 per cent) group, respectively.

In the multivariable analysis, the mortality was lower in the HCQ group compared to the no-HCQ group, the authors wrote.

“In the present study, we retrospectively assessed the association between HCQ monotherapy and in-hospital mortality in a nationwide registry of 8,075 Covid-19 patients,” the authors wrote, adding that it is an observational study of data collected using standardised report forms during the most critical phase of the epidemic in Belgium.

Considering the availability and cheapness of HCQ, it seems worth further investigating the clinical effect of optimised dosage of HCQ and designing “add-on studies in ongoing trials to monitor, beyond the viral shedding and infectiousness, a relevant set of inflammatory markers during the course of SARS-CoV-2 infection”, they emphasised.

“The effect of censoring debate on these early treatments could have possibly been responsible for the death of hundreds of thousands of people.
So, where we should have been having more open debate and more free debate, shutting down debate is likely to have killed people. Not just one or two people, but probably hundreds of thousands. This is why throughout the last 250 years people have said free speech is so important. This is why people have said, ‘I may not agree with what you say but I’ll fight to my death your right to say it.’”
