New York: Generic drugs used to treat heart diseases also have the potential to bolster the immune systems of patients with Ebola virus and some other life-threatening illnesses, research has found.

Unlike other medications in development for Ebola, which attack the virus, statins and angiotensin receptor blockers, typically used for heart disease, work on the host response, or a person’s biological reaction to the virus, said a lead study, authored by  David Fedson, retired professor of Medicine at the University of Virginia in the US.

“The statin or angiotensin receptor blocker combination was found to help improve survival in 100 Ebola patients treated in Sierra Leone”, Fedson said. “This approach to Ebola treatment has two advantages,” he added.

According to him, the first advantage is that it uses inexpensive generic drugs that are widely available in any country with a basic healthcare system, and most physicians who treat patients with cardiovascular diseases are familiar with these medications.  Second, because this strategy targets the host response to infection, these drugs might be used to treat patients with any form of acute infectious disease in which a failure to overcome endothelial dysfunction could lead to multi-organ failure and death, Fedson noted.

In a pilot study, patients were given the drugs atorvastatin (40 mg/day) and irbesartan (150 mg/day) at several hospitals in West Africa.

The researchers found rapid clinical improvement in most patients.

Specifically, the drugs stabilise or restore the integrity of endothelial cells lining the blood vessels.

Endothelial cell dysfunction has been a central feature of human Ebola virus disease, leading to severe fluid and mineral losses, Fedson explained.

The findings appeared in ‘mBio’, the online open-access journal of the American Society for Microbiology.

Eating Eggs May Keep Heart Diseases Away

If you thought eating eggs is bad for your heart due to their high cholesterol content, think again. A large study has now shown that people who consume an egg every day could significantly reduce their risk of cardiovascular diseases.

People suffering from diabetes may finally eat eggs daily without a pinch of guilt. A new study suggests that eating up to 12 eggs a week does not increase cardiovascular risk factors in people with pre-diabetes or Type-2 diabetes.

If you thought eating eggs is bad for your heart due to their high cholesterol content, think again. A large study has now shown that people who consume an egg every day could significantly reduce their risk of cardiovascular diseases.

“The present study finds that there is an association between moderate level of egg consumption (up to one egg/day) and a lower cardiac event rate,” the study authors said.

The researchers pointed out that eggs are a prominent source of dietary cholesterol, but they also contain high-quality protein, many vitamins and bioactive components such as phospholipids and carotenoids.

Cardiovascular disease (CVD) is the leading cause of death and disability worldwide mostly due to ischaemic heart disease and stroke (including both haemorrhagic and ischaemic stroke).

For the study, published in the journal Heart, Chenxi Qin from Peking University Health Science Centre in Beijing, and colleagues set out to examine the associations between egg consumption and cardiovascular disease, ischaemic heart disease, major coronary events, haemorrhagic stroke and ischaemic stroke.

They used data from the China Kadoorie Biobank (CKB) study, an ongoing prospective study of around half a million (512,891) adults aged 30 to 79 from 10 different geographical areas in China.

The researchers focused on 416,213 participants who were free of prior cancer, cardiovascular disease (CVD) and diabetes.

Analysis of the results showed that compared with people not consuming eggs, daily egg consumption was associated with a lower risk of CVD overall.

In particular, daily egg consumers (up to one egg per day) had a 26 per cent lower risk of haemorrhagic stroke, a 28 per cent lower risk of haemorrhagic stroke death and an 18 per cent lower risk of CVD death.

In addition, there was a 12 per cent reduction in risk of ischaemic heart disease observed for people consuming eggs daily, when compared with the ‘never/rarely’ consumption category — about 2.03 eggs per week.

This was an observational study, so no firm conclusions can be drawn about cause and effect, but the authors said their study had a large sample size and took into account established and potential risk factors for CVD. (IANS)
