WHO reassure all: some drugs ’may have an impact’ on COVID-19, but more research needed

الصحة العالمية تطمئن الجميع: قد يكون لبعض الأدوية تأثير على كوفيد-١٩ لكن هناك حاجة إلى مزيد من البحث


World Health Organization officials said early research shows that some drugs “may have an impact” on fighting the coronavirus, but the data are extremely preliminary and more research needs to be done to determine whether the treatments can reliably fight COVID-19.

There is “some preliminary data from non-randomized studies, observational studies, that indicate some drugs and some drug cocktails may have an impact,” Dr. Mike Ryan, executive director of WHO’s health emergencies program, said during a press briefing at the agency’s headquarters Monday.

“A number of drugs” have shown promise in treating other coronaviruses, including SARS and MERS, that may be helpful in fighting COVID-19, he said.

“Some of those drugs may impact the length of disease, some may impact the severity of disease and the dosages of those drugs when they’re given to what patient at what stage of the disease has not been standardized,” Ryan said. “We have never had a comparison group where we’ve had a randomized approach to treatment with the drug or not treatment with the drug.”

“So that we’re clear, there’s no proven effective therapeutic or drug against COVID-19,” he added.

WHO officials were asked about using chloroquine, which is being tested in New York state and has been touted by President Donald Trump as a “game-changer” in treating COVID-19 even though the drug has not been put through a rigorous clinical trial.

On Friday, WHO urged countries to stop using medicines that are not proven to be effective against COVID-19. They did not name any particular drug, but a number of people have been experimentally using chloroquine combined with azithromycin to prevent and treat COVID-19.

“It’s also very important that those drugs are very, very needed for the treatment of other diseases and that we don’t see a situation where people who need those drugs for the treatment of other diseases cannot access them because people are buying them up and using them,” Ryan said Monday.

Chloroquine has gained a lot of attention after a small study of 36 COVID-19 patients published March 17 in France found that most patients taking the drug cleared the coronavirus from their system a lot faster than the control group. Adding azithromycin, commonly known as a Z-Pak, to the mix “was significantly more efficient for virus elimination,” the researchers said. A small study in China also found that combining chloroquine with azithromycin was “found to be more potent than chloroquine.” 

Scientists and infectious disease experts say the study’s findings were not definitive and a large-scale trial is needed to see whether the drugs are effective.

World health officials are testing four of the most promising drugs to fight COVID-19, including chloroquine and hydroxychloroquine, which are anti-malarial drugs.

Dr. Maria Van Kerkhove, head of WHO’s emerging diseases and zoonosis unit, said Monday that there are also a “number of ongoing trials” that look at chloroquine and other drugs, but “many of these trials are small in size, which makes it very difficult to draw any conclusions.”

“That is why it is very important that we have these larger trials … to be able to have enough cases to get an answer as to which drugs work,” she said.


جنيف – قنا

أعلن مسؤولون بمنظمة الصحة العالمية، اليوم، أن أبحاثا أولية أظهرت أن بعض العقاقير قد يكون لها تأثير على مكافحة فيروس كورونا المستجد (كوفيد-19)، لكنهم أشاروا إلى أن هذه البيانات لا تزال مبكرة للغاية وتحتاج للمزيد من الأبحاث.

وقال الدكتور مايك ريان المدير التنفيذي لبرنامج الطوارئ بمنظمة الصحة العالمية، خلال مؤتمر صحفي بمقر المنظمة في جنيف، إن “هناك بعض البيانات الأولية من دراسات غير عشوائية (دراسات رقابية) تشير إلى أن بعض العقاقير وبعض خليط الأدوية قد يكون له تأثير على مكافحة فيروس كورونا المستجد”.

وأضاف ريان أن “عددا من العقاقير” أظهرت تأثيرا واعدا في معالجة أمراض أخرى من سلالة فيروس كورونا، مثل “سارس” و”ميرس”، وهو ما قد يكون مفيدا في مكافحة (كوفيد-19).

وأوضح أن بعض هذه العقاقير قد يؤثر على طول المرض، والبعض الآخر قد يؤثر على شدة المرض.

ومع ذلك، أكد الدكتور ريان مجددا أن كل هذه النتائج لا تزال في مرحلة مبكرة للغاية، ورغم أنها ليست عشوائية، إلا أن مزيدا من الأبحاث ضروري جدا، ولا يزال ليس هناك علاج فعال مثبت ضد (كوفيد-19).

وكانت منظمة الصحة العالمية قد دعت الدول، يوم الجمعة الماضي، إلى التوقف عن استخدام أدوية لم تثبت فعاليتها في مكافحة فيروس كورونا المستجد، دون أن تسمي أي دواء أو عقار بعينه.
