Malaria Drug Chloroquine No Better Than Regular Coronavirus Care, Study Finds Michelle Fay Cortez Small study of 30 patients is early look at highly-touted drug
We’re tracking the latest on the coronavirus outbreak and the global response. Sign up here for our daily newsletter on what you need to know.
Hydroxychloroquine, a medicine for malaria that President Donald Trump has touted as a treatment for coronavirus, was no more effective than conventional care, a small study found.
The report published by the Journal of Zhejiang University in China showed that patients who got the medicine didn’t fight off the new coronavirus more often than those who did not get the medicine.
The study involved just 30 patients. Of the 15 patients given the malaria drug, 13 tested negative for the coronavirus after a week of treatment. Of the 15 patients who didn’t get hydroxychloroquine, 14 tested negative for the virus.
The results of the study weren’t statistically significant.
relates to Malaria Drug Chloroquine No Better Than Regular Coronavirus Care, Study Finds Hydroxychloroquine, particularly when given with the antibiotic azithromycin, has received widespread attention following a controversial, small study of about 40 patients hospitalized with Covid-19 in France. In that study, the drug appeared to help clear the virus from the bodies of 26 patients who were given the medication, based on samples taken from nasal swabs. Experts have criticized the design of the study, calling it interesting but far from definitive.
Trump has said several times that he is confident the medicine will work. On Saturday, Vice President Mike Pence also touted the drug at a White House event.
“Doctors can now prescribe chloroquine for that off-label purpose of dealing with the symptoms of coronavirus,” Pence said. “The president’s very optimistic.”
Top scientists, including White House coronavirus task force member Anthony Fauci, have called reports that hydroxychloroquine might work anecdotal, and said they need further study before the pill’s use is encouraged.
It’s already being given to many hospitalized patients in New York, and larger trials are starting -- part of a broad effort to find anything that might work against the illness.
In the Chinese study, which was conducted by researchers from the department of infection and immunity at the Shanghai Public Health Clinical Center, the 15 patients who didn’t get hydroxychloroquine were treated with conventional care.
This includes bed rest, oxgen inhalation, and the use of anti-viral drugs recommended in China’s treatment guidelines like lopinavir and ritonavir, and antibiotics when necessary.
One patient treated with hydroxychloroquine progressed to severe disease during the study. Four patients given the medicine developed diarrhea and signs of potential liver damage, compared with three getting conventional treatment.
The researchers concluded that additional studies using larger numbers of patients are needed to fully investigate the drug’s risks and benefits.

Can Vitamin D Lower Your Risk of COVID-19? Written by Jillian Kubala, MS, RD on March 26, 2020 Effect on immune health Does it protect against COVID-19? Bottom line Vitamin D is a fat-soluble vitamin that plays a number of critical roles in your body.
This nutrient is especially important for immune system health, leaving many people to wonder whether supplementing with vitamin D may help reduce the risk of contracting the new coronavirus that causes COVID-19.
It’s important to note that there’s currently no cure for COVID-19 and no preventive measures other than social distancing and proper hygiene practices can protect you from developing this disease.
That said, some research shows that having healthy levels of vitamin D, as well as taking a vitamin D supplement, can help keep your immune system healthy and may protect against respiratory illnesses in general.
This article explains how vitamin D affects immune health and how supplementing with this nutrient may help protect against respiratory conditions.
How does vitamin D affect immune health? Vitamin D is necessary for the proper functioning of your immune system, which is your body’s first line of defense against infection and disease.
This vitamin plays a critical role in promoting immune response. It has both anti-inflammatory and immunoregulatory properties and is crucial for the activation of immune system defenses (1Trusted Source).
Vitamin D is known to enhance the function of immune cells, including T-cells and macrophages, that protect your body against pathogens (2Trusted Source).
In fact, the vitamin is so important for immune function that low levels of vitamin D have been associated with an increased susceptibility to infection, disease, and immune-related disorders (3Trusted Source).
For example, low vitamin D levels are associated with an increased risk of respiratory diseases, including tuberculosis, asthma, and chronic obstructive pulmonary disease (COPD), as well as viral and bacterial respiratory infections (4Trusted Source, 5Trusted Source, 6Trusted Source, 7Trusted Source).
What’s more, vitamin D deficiency has been linked to decreased lung function, which may affect your body’s ability to fight respiratory infections (8Trusted Source, 9Trusted Source).
SUMMARY Vitamin D is critical for immune function. A deficiency in this nutrient may compromise immune response and increase your risk of infection and disease.
Can taking vitamin D protect against COVID-19? Currently, there’s no cure or treatment for COVID-19. No studies have investigated the effect of vitamin D supplements or vitamin D deficiency on the risk of contracting the new coronavirus that causes COVID-19.
Still, multiple studies have shown that vitamin D deficiency can harm immune function and increase your risk of developing respiratory illnesses (10Trusted Source).
Additionally, some studies have indicated that vitamin D supplements can enhance immune response and protect against respiratory infections overall.
A recent review that included 11,321 people from 14 countries demonstrated that supplementing with vitamin D decreased the risk of acute respiratory infections (ARI) in both those who were deficient in vitamin D and those with adequate levels.
Overall, the study showed that vitamin D supplements reduced the risk of developing at least one ARI by 12%. The protective effect was strongest in those with low vitamin D levels (11Trusted Source).
Moreover, the review found that vitamin D supplements were most effective at protecting against ARI when taken daily or weekly in small doses and less effective when taken in larger, widely spaced doses (12Trusted Source).
Vitamin D supplements have also been shown to reduce mortality in older adults, who are most at risk for developing respiratory illnesses like COVID-19 (13Trusted Source).
Keep in mind that there’s no scientific evidence that taking supplemental vitamin D can protect you from developing COVID-19. However, being deficient in vitamin D may increase your susceptibility to overall infection and disease by harming immune function.
This is especially worrisome given that many people are deficient in vitamin D, especially older individuals who are most at risk of developing more serious COVID-19-related complications (14Trusted Source).
For these reasons, it’s a good idea to have your healthcare provider test your vitamin D levels to determine whether you have a deficiency in this important nutrient.
Depending on your blood levels, supplementing with 1,000–4,000 IU of vitamin D per day is typically sufficient for most people. However, those with low blood levels will often require much higher doses to increase their levels to an optimal range (15Trusted Source).
Though recommendations on what constitutes an optimal vitamin D level vary, most experts agree that optimal vitamin D levels lie between 30–60 ng/mL (75–150 nmol/L) (16Trusted Source, 17Trusted Source).
SUMMARY Evidence that vitamin D supplements reduce the risk of developing COVID-19 is lacking, but having healthy vitamin D levels can enhance immune health. Plus, vitamin D supplements may protect against respiratory infections in general.
The bottom line Vitamin D plays many important roles in your body, including promoting the health of your immune system.
Scientific research suggests that supplementing with vitamin D may protect against respiratory infections, especially among those who are deficient in the vitamin.
Still, keep in mind that there’s currently no evidence that taking any supplement, including vitamin D, reduces your risk of developing COVID-19 as a result of contracting the SARS-CoV-2 coronavirus.
If you’re interested in supplementing with vitamin D to enhance your overall immune response, consult your healthcare provider for information on proper dosing.
