French expert says second study shows malaria drug helps fight coronavirus

PARIS: The controversial French professor who believes the anti-malaria drug chloroquine can help beat the coronavirus, has claimed that a new study he has conducted confirms its "efficiency" at combatting the virus.

But several other scientists and critics of microbiologist Didier Raoult, who heads the infectious diseases department of La Timone hospital in Marseille, were quick to cast doubt upon his findings.

They said the testing was not carried out in a controlled study and that the results were purely "observational". Dr Raoult, whose theory has been taken up by US President Donald Trump, said his new study of 80 patients showed that four out of five of those treated with the drug had "favourable" outcomes.

He had earlier reported that after treating 24 patients for six days with hydroxychloroquine and the antibiotic azithromycin, the virus disappeared in all but a quarter of them. The research has not yet been peer reviewed nor formally published in a medical journal. No stranger to controversy, the colourful scientist with shoulder-length blond hair and grey beard, insists that the Chinese pulmonary expert Zhong Nanshan observed a similar pattern.

Raoult's critics have pointed to problems with the protocol of his testing and worrying side effects of the drug. Fakemed, a group of scientists against fake news in health, lambasted the 68-year-old professor.

After Raoult released his latest findings on the internet over the weekend, Professor Francois Balloux of University College, London, tried to dampen talk that the drug could be a silver bullet.

"No, (this is) not 'huge' I'm afraid," he said on Twitter. "This is an observational study (i.e. not controlled) following 80 patients with fairly mild symptoms. The majority of patients recover form #COVID19 infection, with or without #Hchloroquine and #Azithromycin treatment."

Statistician Tim Morris of the university's clinical trials unit was even more scathing. "If hydroxychloroquine turns out to be useful," he tweeted, "it's a shame that this group will be praised as heroes and prophets instead of held to account for the misinformation and self-promotion they´ve been churning out at a critical time."

Chloroquine and hydroxychloroquine, which is often sold as Plaquenil, have been hailed as a potential "gamechangers" by Trump, but US government experts are as yet unconvinced, with Dr Anthony Fauci, the head of the US National Institute of Allergy and Infectious Diseases, calling the results so far "anecdotal". At least one person has already died in the US after self-medicating with a non-pharmaceutical version of the drug used for cleaning fish tanks.
