High priced anti-viral drugs do NOTHING to prevent hepatitis C, study finds


The word “hepatitis” refers to inflammation of the liver, and can have several causes, including heavy alcohol use, exposure to toxins, or a bacterial or viral infection. There are three different types of viral infections: hepatitis A, hepatitis B and hepatitis C, which are caused by different viruses, and have different methods of transmission. Among this family of viruses, hepatitis C is the most dangerous, and is spread through contact with the blood of an infected person. A hepatitis C infection can last a lifetime, and can cause serious damage to the liver, ultimately resulting in cirrhosis (scarring) or even liver cancer. Hepatitis C kills about 700,000 people globally each year.
It is understandable, therefore, that the announcement of the release of an antiviral drug marketed as a “miracle” cure for hep C was received with great joy by many. However, a damning new study by the Cochrane Collaboration in Copenhagen, Denmark, has found that this $40,000 “miracle” cure might not be quite so miraculous, after all.
Though the astronomical price tag might have been out of the reach of many, there were lots of other patients who were more than happy to pay to avoid the death sentence so often attached to a hep C diagnosis.
These direct-acting antiviral drugs (DAAs) promise to completely clear the virus from the blood within 12 weeks, and it would seem that they do successfully fulfill this specific obligation.
In assessing all the DAA drug company trials, however, the Danish researchers determined that while clearing the virus from the blood, there is no evidence that these treatments actually fully remove hep C from the body. Their concern is that the virus may continue to linger elsewhere in the body, and in the sickest, stage 3 or 4 patients, could return and cause end stage liver disease.
The researchers also noted that according to the 138 clinical trials reviewed, there were few deaths in either the placebo group or among those actually taking the DAAs.
Since all the trials were conducted under funding from the drug companies themselves, the study authors also expressed concerns about the “high risk of bias.”
“It is never possible to show that something does not work, but there is no evidence [that they do],” said Janus Christian Jakobsen, chief physician at a clinical trial unit in Copenhagen and the deputy coordinating editor of the Cochrane Hepato-Biliary Group. “Our results indicate [the drugs] may have no clinical effect.”
The authors concluded that with the lack of evidence that these drugs even work, as well as the potential that they might harm people, healthcare providers should think carefully before administering DAAs for the treatment of chronic hepatitis C.
Of course, the pharmaceutical companies are refusing to accept the results of the report.
AbbVie, one of these manufacturers, doggedly insists that both “controlled trials and real world experience” contradict the findings of the report.
“A cure in [hepatitis C] is defined as undetectable virus in the blood 12 weeks after completing treatment and, in the U.K., fewer than 1% of people treated with AbbVie’s therapy did not achieve this,” a company representative told The Guardian.
While a 2015 report by Public Health England pointed to an 8 percent decrease in end-stage liver disease, along with a decrease in liver transplants after the introduction of DAAs, the Cochrane researchers are adamant that there is no evidence proving their efficacy.

The jaw-dropping price tag of these drugs has also caused immense concern worldwide. The World Health Organization (WHO) warned in 2016 that no country in the world could afford to treat all its hep C patients with such expensive drugs. Of course, their pleas fell on deaf ears. Big Pharma is happy as long as it’s making a profit, no matter who gets hurt along the way.

Tattoos may lead to HEAT STROKE by impairing your skin’s natural sweat production

Tattoos may increase the risk of suffering heat stroke, a small study found. To carry out the study, researchers at Alma College, Michigan used a drug called pilocarpine to induce sweating among participants, then collected the sweat samples. The first batch of samples were taken from the tattooed skin, while the other batch was taken from the participants’ non-inked skin at the opposite side of the body. Sweating is a key component of the body’s temperature regulation. Perspiration helps the body cool down as sweat evaporates from the skin.
According to the study, tattooed skin produced less sweat and contained higher sodium concentration compared with the non-tattooed skin. “We are not sure whether it is the ink or the trauma or a combination of both that is responsible for the results that we saw,” said study author Maurie Luetkemeier in DailyMail.co.uk. However, researchers inferred that tattoos inhibit the skin from releasing heat during warm weather. Limited heat loss in turn may lead to higher body temperature and significantly increased risk of heat exhaustion and heatstroke.
The findings were published in the journal Medicine & Science in Sports & Exercise.

Tattoo-related health risks are beyond skin deep

Tattoos have become a pop culture staple over the last few decades. In fact, recent statistics showed that 45 million Americans have at least one tattoo. According to statistics, 36 percent of adults aged 18 to 25 years, and 40 percent of adults aged 26 to 40 years have at least one tattoo. The tattoo industry is estimated to generate revenues of up to $1 billion by 2020.While considered an art form on its own, tattoos pose health risks that go beyond skin deep. These risks include a wide range diseases from chronic allergies to cancers.
A 2015 study found that tattoos induced both short-term and chronic complications in participants. In order to assess the adverse effects of tattoos, researchers examined 300 tattooed participants and found that 10 percent of them experienced some form of short-term complications such as bacterial infection, swelling, and itching. Among these participants, about six in 10 suffered chronic complications. However, researchers found that while many participants experienced swelling or itching for years, few have actually allotted time to have the symptoms checked. The findings were published in journal Contact Dermatitis.
In 2016, the U.S. Food and Drug Administration (FDA) issued new warnings about health risks associated with tattoo ink such as allergic reactions and infections.
Another study revealed that tattoo exposure was linked to an increased risk of hepatitis C infection. The infection can be transmitted through contaminated needles. As part of the research, health experts at Tulane University School of Medicine examined nearly 2,000 patients and found that HCV-infected patients were more likely to have one or more tattoos compared with non-infected controls. The results suggest that “tattoo exposure is associated with HCV (hepatitis C virus) infection, even among those without traditional risk factors. All patients who have tattoos should be considered at higher risk for HCV infection and should be offered HCV counseling and testing,” the researchers wrote in MedicalDaily.com. The findings appeared in the journal Hepatology.
A report by the European Chemicals Agency (ECA) noted that tattoo ink may contain potentially toxic chemicals that may trigger cancer onset. According to the agency, red inks appeared to be the most potentially hazardous color. The report has also stressed that blue, green, and black inks may also lead to certain adverse health effects. “Many reports show concerns for public health stemming from the composition of inks used for tattooing. The most severe concerns are allergies caused by the substances in the inks and possible carcinogenic, mutagenic or reproductive toxic effects,” the agency stated in an article in News.com.au.
