Accutane: miracle acne drug or miserable medication?

All Carli Watkins wanted was to walk out of her apartment without putting on make up.

Severe acne covered her face all through high school and into college, so Watkins, a Holton senior, and her doctor searched for years for a cure to this problem and her personal embarrassment.

“I went through every pill, cream, face wash and lotion imaginable,” Watkins said. “Nothing was working. I felt dirty and like no one understood how hard I was trying to get rid of it.”

Nothing, that is, until her dermatologist decided to prescribe Accutane, the strongest acne medication on the market. Watkins said she had heard of the dangers but was so frustrated that she was willing to try anything.

Accutane, what some dermatologists have called the “miracle drug” of acne medicine, has serious side effects that have deterred some patients and left others wondering if the risks are worth it.

The medicine can cause joint inflammation, vision changes, sun sensitivity, hair loss, high cholesterol and blood pressure, birth defects in babies and possibly depression.

According to the FDA, Accutane, a medicine from Roche Laboratories that releases high dosages of vitamin A in the body, entered the market in 1982 to treat severe nodular acne. This type of acne forms large pimples on the skin and usually leaves large scars.

Dr. Matthew Buxton, dermatologist at Free State Dermatology in Lawrence, said Accutane is often a last resort medicine because it is so powerful.

“I usually go through other medicines with people before prescribing Accutane,” Buxton said. “Occasionally, though, I get someone with such severe acne or great scarring that I start them right away.”

Watkins went to her family doctor for more than four years, experimenting with nearly every acne product on the market. She said it was extremely frustrating to use multiple products and go through so much money for prescriptions with no results.

Andrew Jennings, Silver Lake junior, finished his cycle of Accutane in October. He suffered the same frustration as Carli.

“I’ve had acne since seventh or eighth grade,” Jennings said. “I had tried everything possible that was over-the-counter or prescribed by my doctor.”

Though Dr. Buxton said if taken properly, Accutane could be a safe medication, it’s a risky game for some acne patients.

Watkins took Accutane her sophomore year at KU, and she said she had dry, itchy skin and some surprising side effects.

“Everything on me was dry,” Watkins said. “My lips were unbelievably chapped, and the bottom of my feet cracked. When I first started taking it, my stomach hurt so badly, I couldn’t eat for a couple days.”

She said she also couldn’t wear contacts for weeks at a time because her eyes were too dry, and she lost interest in activities she once enjoyed, like volleyball.

“I just didn’t feel good—my skin was peeling, and I looked like crap,” Watkins said. “I just didn’t want to do anything or go anywhere.”

Jennings said dryness was his main side effect, also.

“My lips were chapped and hands were dry, and I started to get bloody noses pretty often,” Jennings said.

Female patients are the biggest concern to dermatologists, as Accutane causes serious birth defects or miscarriages. Roche takes these risks seriously and provides strict guidelines to women before they begin Accutane.

Shelley Rosenstock, executive director of public affairs at Roche, said women must take two pregnancy tests initially and one each month before being prescribed a new dosage of the medicine. She said women must also use two forms of birth control while on Accutane.

Accutane packets contain warning labels about side effects like birth defects. Perforated pull tabs, left, cover every Accutane pill and must be removed before the medicine can be consumed. Drawings like the deformed child appear on each packet to remind female patients of the risks of pregnancy.

“A new iPledge program began in 2005 requires monthly documentation of the patient’s contraception choice by both the patient and the prescriber,” Rosenstock said.

Watkins remembers being asked monthly if she could be pregnant and if she was using birth control.

While the FDA is ensuring that Roche adequately informs patients of pregnancy risks, the medicine has faced other criticism because of a possible link to depression.

Though the medical community is still at odds as to whether Accutane causes depression, the FDA reports that through 2005, 190 Accutane patients have committed suicide.

Dr. Buxton said he hasn’t seen a link between the two, and he was caught off-guard when Roche began adding labels to the medication that warned of depression.

“I don’t know if it’s just reports that have made people more aware of the risk,” Buxton said, “but people in their teens and twenties are the most likely to be depressed anyway.”

Watkins said she became more wary of the medicine when she had to sign a “huge packet of forms” stating she understood all of the dangers of Accutane, and her doctor asked her monthly about her mental state.

Jennings also had to take steps before beginning the medicine.

“I had to watch this movie that talked about all of the side effects, even though most of it was about getting pregnant,” Jennings said. “The doctor also warned me every time not to give Accutane to anybody else.”

Bill Axcell, pharmacist at Jayhawk Pharmacy, said the number of prescriptions for Accutane has declined recently, and he now fills only about two per month.

“I think people are finding out about all of the side effects with pregnancy and depression and the national registry with iPledge,” Axcell said.

The high price is also discouraging to some acne patients. Axcell said that without insurance, a 30-day supply of Accutane costs $550.

Carli Watkins is unsure if she take Accutane again, knowing everything she has been through. Her face is now clear, but getting to that point was painful and expensive.

“When you’re on it, you feel absolutely miserable,” Watkins said. “If I had known what all would happen, I don’t know if I’d be willing to go through it again if I had to.”

Dark chocolate sales surge, KU left behind

Dark chocolate, a product receiving local and national attention because of its health benefits and subsequent rising sales, has yet to make an appearance in KU vending machines.

Treat America Food Services owns the 40 snack machines on the Lawrence campus. Rita Zuniga, purchasing employee, said that some company sites do receive dark chocolate, but older products are involved in selection.

“The best-selling candies in the market are standard,” Zuniga said. “Nestle and M&M/Mars always provide the basics.”

The lack of dark chocolate at the University comes at a time when national sales are booming because of studies that have come out in the last few years touting the health benefits of the dark candy.

Chuck Teater, vice president of quality at Russell Stover corporate headquarters in Kansas City, Mo., said their company’s dark chocolate sales have seen a significant growth, especially in the last year.

“The trend started a couple of years ago, but as the benefits have received more publicity, we have noticed a bigger growth in the past year,” Teater said.

Dark chocolate sales are surpassing those of milk chocolate in some locations. One Russell Stover store in Kansas City, Mo., has seen greater sales of different dark chocolate varieties so far this year.

Nationally, Mintel International reports that sales have risen nearly 30 percent between 2003 and 2005. Dark chocolate sales totaled more than $1.6 billion in the United States in 2005 alone.

Dark chocolate has become popular because flavanoids, a group of compounds in cocoa plants, help reduce cholesterol and blood clotting problems.

Cheryl Wetherington, owner of Riverfront Chocolates in Lawrence, said the higher the percentage of pure chocolate, the healthier it is.

“Our newest chocolate is 72 percent pure chocolate,” Wetherington said. “Milk chocolate only has 38 percent.”

Because there is more pure chocolate in each treat, dark chocolate is more expensive to make than milk chocolate. Wetherington estimated that it cost her company about $1 more per pound of dark chocolate than milk chocolate. However, Riverfront Chocolates, which is located in the SpringHill Suites lobby, sells both varieties at the same price.

Sharry Bowden, vice president of vending at Treat America, said the major reason for the absence of dark chocolate on campus is not price-based.

“Right now, there aren’t a great number of products available,” Bowden said. “As companies begin to promote dark chocolate, we’ll begin to promote it.”

The rise in popularity of dark chocolate has led some businesses to create new strategies. Riverfront Chocolates is devoting a section of their store solely to the dark confections. Currently, between 20 percent and 25 percent of the business’ sales come from dark chocolate, whereas the industry average is about 15 percent, Wetherington said.

Teater said Russell Stover is also looking to capitalize on the national trend.

“In about six months, we will be releasing a new line of dark chocolates,” Teater said. He said there would be at least 20 new products.

The chocolate industry has also taken advantage of reports of increased heart health and circulation from dark chocolate by adding labels to products or verbally raising awareness of benefits. Hershey’s dark chocolate packages contain a special “natural source of flavanol antioxidants” label that alerts consumers to the advantages of the extra cocoa in their product.

Ann Chapman, coordinator of nutritional services at Watkins Memorial Health Center, said that labels like this carry a risk of consumer abuse.

“You’re always going to have a potential for abuse or misuse when foods, all of a sudden, have health benefits,” Chapman said. “I would recommend dark chocolate in very small amounts.”

Chapman said a bar of Hershey’s Special Dark chocolate has 531 calories, so servings should be cut in small portions to avoid overeating.

Treat America has a “Right Choice” campaign that helps vending machine customers discern which items meet certain health requirements. Zuniga said that dark chocolate probably would not make the grade.

“We look for items that are low in fat, calories and sugar,” Zuniga said.

Delaina Lenard, Riverfront Chocolates customer, said that the health benefits don’t sway her to buy dark chocolate; she just likes good chocolate.

“I am not very choosy when it comes to chocolates,” Lenard said. She said she especially likes Riverfront Chocolates and refers them to her corporate office for holiday packages.

With the holiday season approaching quickly, Wetherington said the weather and the spirit of giving bring more business to the industry, and dark chocolate, in particular.

“Around Christmas, business increases 20 to 25 percent,” Wetherington said. “This is actually fairly low for the industry, which sees a 50 percent increase normally.”

Treat America’s vending business is consistent with the academic calendar at KU.

Bowden said the company may be stocking machines with some dark chocolate in the future.

“We will definitely start rotating in more dark chocolate as more products become available. For example, I know that Mars Co. just introduced new dark chocolate M&M’s.”

New vitamin deficiency link and supplements may help treat alcoholism

A new theory on a vitamin deficiency proposed by a KU Medical Center researcher may change the future of familial alcoholism.

Dr. Ann Manzardo, research assistant professor of psychiatry and behavioral science, has found a link between a thiamine deficiency early in life and adult alcoholism. Manzardo said that thiamine, a B vitamin important for all cells, is often lacking in alcoholics.

“A thiamine deficiency has long been linked to alcoholism,” Manzardo said. “We now believe that the deficiency may be predisposing people to alcoholism instead of being the result of alcoholic behavior.”

Thiamine helps to break down sugars and turn them into energy. The heart and nervous system are especially prone to a deficiency, which occurs when proteins do not “turn on” the thiamine to run throughout the body. Thiamine also keeps nerves functioning normally.

Manzardo’s theory, which appeared in the September issue of Alcoholism: Clinical and Experimental Research, suggests that some babies may have an inherited insensitivity to thiamine that inclines them to alcoholism later in life. This adds to the proven data that alcoholism is a genetic disease.

Manzardo said that white matter, a fatty substance that protects cells in the nervous system, sometimes does not develop properly in the first few weeks of life when there is a thiamine deficiency. This can lead to permanent problems, including adult alcoholism.

“Individuals with white matter damage may have impaired judgment when using alcohol and may be less able to stop themselves from drinking too much,” Manzardo said.

Previous studies have found that children of alcoholic parents develop at a slower rate, and their motor skills are especially impaired. White matter damage in the brain that results from a thiamine deficiency is now believed to be the cause of those developmental issues.

http://reporting.journalism.ku.edu/fall06/fred-musser/upload/2006/10/alcohol-dependence-at-30-thumb.gifChildren who have white matter damage to the brain develop more slowly and are much more likely to become alcohol dependent by age 30 than those who develop at a normal rate.

Manzardo said that the inherited deficiency is a major link to alcoholism later in life, as children with alcoholic parents are at a much high risk of abusing alcohol themselves.

“Sons and daughters of alcoholics are two to four times more likely to become alcoholics themselves,” Manzardo said.

Wally Mechler is the owner of W.E. Mechler Counseling. He is licensed to treat alcohol addictions, and he said that significant medical research has linked the genetic qualities of alcoholism.

“Between 60 and 70 percent of my patients actively report that they have at least one parent who is an alcoholic,” Mechler said.

One reason alcoholism is so difficult to study is because the gene connected with the disorder has not yet been found. However, if Manzardo’s theories prove to be correct, isolating the gene may become much easier. Right now, though, testing theories involves creativity, as gathering the data from birth to adulthood is an extensive process.

Manzardo said that she hopes to assess preteens with an inherited thiamine deficiency before they begin drinking and interview them again in 10 years, noting how many have become alcoholics.

The future of familial alcoholism may also be altered by a supplement Manzardo is currently testing. Benfotiamine is a dietary supplement that was created in the 1960s to help with side effects of drinking. It has recently been used to help diabetics, who have blood sugar problems that relate to the thiamine deficiency. A diabetic’s body can break down sugars properly with the aid of Benfotiamine.

Manzardo said that the drug activates thiamine in the body and dramatically increases the vitamin’s levels. It has been shown to improve brain function in alcoholics.

“We will see if the supplement has an effect on drinking and whether it will help alcoholics recover,” Manzardo said.

The supplement has been very successful in Europe at reducing the symptoms of nervous system conditions involved with alcoholism, and no adverse effects have been found. Manzardo said Benfotiamine could eventually be used to help those who have the thiamine deficiency before they abuse alcohol.

“Ultimately, it makes sense to give it to pregnant women or babies,” Manzardo said, “especially people who have a high risk for alcoholism.”

Manzardo said the supplement could improve or reduce the risk of alcoholism later in life. However, she said she would not recommend this without extensive testing that proves there are no negative side effects.

Mechler said there are many medications out now that help combat cravings, and he sees potential in Benfotiamine.

“If it was approved by the correct governing agencies, I would advocate anything that is safe to help,” Mechler said. “I promote supplements, and it is also about a holistic lifestyle.”

Benfotiamine has the opportunity to change the face of adult alcoholism by controlling symptoms before birth and in the earliest stages of life. Manzardo said this could decrease pregnancy complications, increase development rates, and in time, lead to fewer cases of alcoholism.
