Guest guest Posted September 9, 2001 Report Share Posted September 9, 2001 PSORIATIC ARTHRITIS NEWS AND VIEWS VOLUME 1 ISSUE 2 SEPTEMBER 2001 PSORIATIC ARTHRITIS MEDICAL NEWS We reported in our first newsletter about the new psoriasis drug under test called " Alefacept. " This issue begins with additional information as reported in the New England Journal of Medicine. Alefacept Reduces Severity of Chronic Plaque Psoriasis WESTPORT, CT (Reuters Health) Jul 26 - Alefacept (Amevive; Biogen) appears to be an effective and well-tolerated immunomodulatory treatment for chronic plaque psoriasis, according to results of the multicenter Alefacept Clinical Study, which appear in the July 26th issue of the New England Journal of Medicine. " Alefacept was designed to interfere with the co-stimulatory pathways that occur when an antigen-presenting cell meets a memory T cell, " co-investigator Dr. Gerald G. Krueger, of the University of Utah Health Sciences Center in Salt Lake City, told Reuters Health. " We were hoping it would also hook onto a natural killer cell and therewith eliminate the memory effector cell that causes psoriasis. " " As we demonstrate in our paper, there is a direct correlation between memory effector T cells and improvement in disease, " he said. Dr. Krueger and associates randomly assigned subjects to alefacept (170 patients) or placebo (59 patients). The treatment group received alefacept in doses of 0.025, 0.075, or 0.150 mg/kg, administered IV once a week for 12 weeks. Five placebo group patients and three alefacept patients discontinued treatment because of worsening of psoriasis. Two weeks after completion of alefacept treatment, mean scores on the psoriasis area-and-severity index were lower than baseline by 38%, 53%, and 53% in patients receiving 0.025, 0.075 and 0.150 mg/kg, respectively. These scores were significantly lower than the 21% decline observed in the placebo group (p < 0.001). Twelve weeks after treatment, between 42% and 63% of patients treated with alefacept had at least a 50% reduction in baseline score, compared with 32% of those given placebo (p = 0.02). Between 19% and 33% of patients who received alefacept exhibited at least a 75% reduction versus 11% in the control group (p = 0.02). These results were mirrored in the group's recently completed phase III trial, Dr. Krueger told Reuters Health. In this trial, more than 1000 patients were treated with alefacept 0.075 mg/kg, either IM or IV. " Again, we saw a delayed response, " he said. " If someone achieved 50% or 75% improvement immediately post-treatment, they either stayed there or got better during the next 12 weeks. At the end of 12 weeks, they were offered another course. " Twenty-three percent of the psoriasis cases cleared after the first course of treatment and 32% cleared after the second course. The study group also looked for evidence of infections that would be anticipated if T-cell counts declined in a generally immunosuppressive mode, especially fungal infections, Pneumocystis, herpes simplex, and herpes zoster. ************************************* Editors note: The following article from the Southern Medical Journal makes reference to the possible connection between cigarette smoking and psoriasis. I have chosen to include only a very small portion of the information because of the length of the study. The following is the web site address should you desire to read the entire publication. http://www.medscape.com/SMA/SMJ/2001/v94.n06/smj9406.14.stra/smj9406.14.stra-0 1.html Tobacco Use and Skin Disease Melody Vander Straten, MD, Carrasco, MD, Martha S. Paterson, MD, L. Mccrary, MD, Diane J. Meyer, MD, K. Tyring, MD, PhD, Galveston, Tex [south Med J 94(6):621-634, 2001. © 2001 Southern Medical Association] Abstract Background The primary objective of this review is to evaluate the mucocutaneous manifestations of tobacco use. Methods. Computerized literature searches were conducted for English language articles related to skin/mucous membrane disease and use of tobacco. The primary criterion for assessing data quality and validity was the demonstration of a causal relationship between tobacco use and skin/mucous membrane disease. Results. This review of the literature shows that a number of disorders and diseases of the skin and mucous membranes are related to tobacco use. Conclusions. Since millions of persons use tobacco despite its well publicized relationship to increased mortality, knowledge of the mucocutaneous morbidity associated with tobacco use may help physicians in counseling their patients. Psoriasis (A paragraph taken from a section of the study) Many researchers have shown a relationship between smoking and psoriasis, especially palmopustular psoriasis. O'Doherty et al[21] showed that palmopustular psoriasis was associated with a high prevalence of smoking. In addition, Mills et al[22] showed that in plaque psoriasis, there was a significantly higher prevalence of current smoking (46%) as compared with matched controls (24%), and more patients with psoriasis had smoked before the onset of psoriasis (55%) as compared with controls (32%). Finally, the daily consumption of cigarettes correlated with the risk of developing psoriasis, with the higher number of cigarettes smoked (more than 20 cigarettes per day) being associated with greater risk. This was confirmed by Poikolainen et al,[23] who found that among psoriatic women the mean number of cigarettes smoked was 8.6 compared with 4.7 for controls. It should be noted that some treatments for psoriasis are flammable and therefore may pose a danger to smokers. Key Points Dermatologic effects of cigarette smoking include facial wrinkling, facial gauntness, complexion color changes, decreased skin moisture, yellowed nails, harlequin nails, halitosis, nicotine stomatitis, and skin burns. Indirect effects of cigarette smoking include poor wound healing; psoriasis; atherosclerotic peripheral vascular disease; Buerger's disease; Raynaud's disease; diabetic foot disease; oral yeast infections; condyloma acuminatum; and cutaneous findings in HIV and AIDS, Crohn's disease, and malignancies. Recognition of dermatologic signs of tobacco use can be a clue to many of the serious underlying systemic diseases associated with smoking and also with use of smokeless tobacco. ************************************ TB Test Required For Arthritis Patients Wishing To Take Remicade August 16, 2001 WASHINGTON (AP) - Rheumatoid arthritis patients must be tested for tuberculosis before they begin taking a treatment called Remicade, the drug maker and the government announced. Patients using Remicade are at least four times more likely than average Americans to get active tuberculosis, the Food and Drug Administration estimates. The problem: Apparently the drug suppresses users' immune systems enough that if they unknowingly carry the TB germ, the respiratory illness can suddenly flare up. The warning is serious because untreated, TB can kill - and it's also an airborne illness that these patients could spread to family and friends. Worldwide, 88 cases of tuberculosis have been reported among the estimated 170,000 people who have tried Remicade, FDA's Dr. Bill Schwieterman said Wednesday. Fifteen of those people died. Some 2 billion people worldwide are infected with TB and risk developing an active case of the disease. In the United States, TB cases dropped to a record low of 16,377 last year. But the illness is a continuing threat here, with increased foreign travel and immigration from countries where TB is common. Rheumatoid arthritis afflicts more than 2 million Americans when their immune systems go awry and attack their joints, causing severe swelling, pain and stiffness. Remicade is a bioengineered drug that roams patients' blood to sop up an immune system protein called tumor necrosis, a factor responsible for much of the swelling. But that immune suppression, so important in fighting rheumatoid arthritis, can leave users at a higher risk for serious infections. Remicade's label has long carried warnings about various infections, but it now will carry a boxed warning in bold type about the TB risk - the strongest warning possible for a prescription drug. The warning doesn't say people should stop using Remicade. The risk of activating latent TB appears highest in the first three to six months of use, so doctors should carefully evaluate those patients, Schwieterman said. But before prescribing Remicade to a first-time user, doctors should test for TB - it's a simple skin test - and treat TB carriers, the FDA concluded. Manufacturer Centocor Inc. will send letters to thousands of doctors who prescribe Remicade, both for rheumatoid arthritis and the bowel ailment ailment Crohn's disease, alerting them to the warning. A similar rheumatoid arthritis treatment called Enbrel also suppresses the immune system and carries warnings that users face the risk of serious infections. But so far, Enbrel users don't seem to face a special TB risk, Schwieterman said. Copyright 2001 The Associated Press.

Advisers to the Food and Drug Administration recommended on a 6-2 vote that Amgen Inc.'s Kineret be approved. Studies found that about 15 percent more patients who took Kineret than who received a dummy shot saw improvement in joint swelling and pain. Other treatments sold today come with higher effectiveness rates. But experts note that those drugs don't help everyone so additional options are needed. Kineret, known chemically as anakinra, works differently than other therapies, by blocking a protein called interleukin-1 that is one cause of the swelling associated with arthritis. Side effects included irritation at the drug's injection site and a small risk of serious infection. The FDA is not bound by its advisers' recommendations but typically follows them.

My own intimate involvement with the subject began in 1989. I had a heart attack, discovered I have CAD which runs in the family, had my last cigarette after 35 years, experienced 7 angioplasties and 4 stents over 8 years, lost 25 pounds through diet and exercise, started daily vitamin therapy and lipid lowering medications, and made some other lifestyle changes too. So this subject is very near and dear to my heart. No pun intended of course. Antioxidant Supplements Reduce Benefits of Lipid-Lowering Drugs MedscapeWire August 10, 2001 By Hong Mautz New York - Taking antioxidant vitamin supplements with 2 substances commonly prescribed to lower cholesterol can sharply diminish a key beneficial effect of the therapy, warns a new study. Some experts say these latest negative findings about the popular supplements strongly suggest that the vitamins should not be used to treat or prevent heart disease. Researchers examined nearly 150 people who had both coronary artery disease (CAD) and low levels of high-density lipoprotein (HDL) cholesterol. They were given niacin (vitamin B3) and simvastatin. Close to half of the subjects also were given a cocktail of antioxidant supplements that included vitamins E and C, beta-carotene, and selenium. Rather than helping patients with CAD, however, the antioxidants limited the effectiveness of the niacin-simvastatin combination. " We found that there was an adverse interaction between the antioxidant cocktail and the lipid-lowering therapy, " says Greg Brown, MD, PhD, co-author of the study, which is published in the August issue of Atherosclerosis, Thrombosis, and Vascular Biology. " The adverse effect on HDL appeared specific for the HDL2 component, which is responsible for most of the risk-reducing benefits of HDL. " After a year of treatment, the combination of simvastatin and niacin with the antioxidant vitamin supplements increased HDL2 by 15% compared with 60% in patients who did not receive the supplements. " There is a substantial reduction in the rise of HDL2, the most protective component of HDL, " says Brown, a professor of medicine in the cardiology division of the University of Washington in Seattle. " The effect is detrimental when antioxidant vitamins are taken with the lipid-lowering drugs. " In an editorial accompanying the study, Kuller, MD, DrPH, professor and chairman of the Department of Epidemiology in the School of Public Health at the University Of Pittsburgh, Pennsylvania, says that physicians should be cautious about promoting antioxidant vitamins in patients with CAD. " All the hype about antioxidant vitamins being a big winner in preventing heart disease is totally unproven, " says Kuller. " For people who are on lipid-lowering drugs such as niacin, a combination with vitamin E is not a good choice. " Only a diet rich in antioxidants has been proved to be associated with a low risk of CAD, he says. " People who take vitamins are a highly selected group of individuals who are interested in their health, so they often don't smoke, they exercise and weigh less, and they are often better educated, " explains Kuller. " That may be one of the reasons they are healthier: It doesn't have anything to do with taking vitamins. " The American Heart Association does not recommend using antioxidant vitamin supplements to maintain or increase cardiovascular health; instead it recommends eating a variety of foods daily from all of the basic food groups. ************************************ Cholesterol Drug Warnings Urged August 21, 2001 WASHINGTON (AP) - Nearly two weeks after a popular cholesterol-lowering drug was pulled off the market for causing deadly muscle destruction, a consumer group charged Monday that five similar medications have killed an additional 81 people. Public Citizen petitioned the government to force manufacturers to give special warning brochures to the millions of Americans who take those medicines - statins - telling them to quit the pills at the first sign of muscle pain or weakness. Statins dramatically lower cholesterol and reduce patients' risk of heart attacks. " Most people taking these drugs aren't aware that they could sustain serious muscle damage and could even die, " said Dr. Sidney Wolfe of Public Citizen's Health Research Group. " Serious muscle and kidney damage, and potentially death, may be averted only if the patients taking statins stop the drugs at the first sign of muscle pain or weakness, " Wolfe wrote the Food and Drug Administration Monday. The FDA disputed Wolfe's death count, saying its own investigation last year uncovered just 18 deaths that could be linked to the five statins on the U.S. market - Lipitor, Mevacor, Pravachol, Zocor and Lescol. But the agency will consider Wolfe's request for stiffer warnings. Pfizer Inc. already has asked the FDA to approve a brochure written in layman's language that would accompany every bottle of the top-selling statin Lipitor, explaining the risk. Wolfe's petition comes almost two weeks after one statin, Baycol, was pulled off the market when the FDA linked it to 31 U.S. deaths from a side effect called rhabdomyolysis. That's a rare but life-threatening condition in which muscle cells are destroyed. In severe cases, it leads to kidney failure. Every statin has been linked to rare reports of a muscle side effect, and their labels carry that warning. Wolfe analyzed FDA records to uncover 772 cases of rhabdomyolysis since 1997 among the six statins sold in this country. Half - 387 cases - were caused by Baycol alone, explaining why Bayer pulled it off the market. But Wolfe said he found another 385 rhabdomyolysis cases among users of the other five statins still sold, including 81 deaths dating back to 1987, when the first of those drugs hit the market. That's still a rare risk, considering 8 million Americans are estimated to use statins. But Wolfe argues that severe muscle destruction and death are preventable if patients are aware of the early warning signs. He urged the FDA to put stronger warnings on the statins' labels, to write every U.S. physician telling them about the risk, and to mandate that every patient get a brochure with each bottle telling them to stop the pills and call a doctor if they suffer muscle symptoms. A closer look at the FDA's reports shows duplicates and patients who actually died of other causes, leading federal health officials to link just 18 rhabdomyolysis deaths to statins during an investigation last year, said FDA's Dr. . Merck & Co., maker of Zocor and Mevacor, says it provides Zocor users a layman's explanation of the muscle side effect on its Internet site. Bristol-Myers Squibb is seeking to capitalize on Baycol's departure with full-page newspaper ads of Pravachol that mention the muscle risk, but company spokesmen didn't return calls seeking comment Monday. Lescol-maker Novartis maintained the risk is small and that patients are appropriately warned. Copyright 2001 The Associated Press.

The statement came in response to a recent petition filed with the US Food and Drug Administration (FDA) to require " black box " warnings, the strongest warning the FDA can mandate, on all of the cholesterol-lowering drugs. Public Citizen, a consumer advocacy group, filed the petition earlier this week, soon after the statin Baycol (cerivastatin) was pulled from the market because of reports of rhabdomyolysis and deaths related to the muscle disorder. " We know that the FDA looks carefully at adverse drug reactions to determine if special warnings or labels are warranted, " said Sidney , MD, Chief Science Officer of the American Heart Association. " After careful review of the available information on the statin class of drugs, the FDA should be in the best position to determine whether special labeling will be effective. " encouraged open communication between physicians and their patients. " Doctors should warn their patients to be on the watch for potential side effects of any medication. And patients need to take the initiative and call their physician if they experience an unusual side effect. Appropriate labels can also be a valuable tool in patient education. " In the case of statins, patients should watch for muscle aches and pains, dark urine and other signs and symptoms as noted by the FDA and the package insert included with the medicine. The AHA emphasizes that lifestyle decisions such as diet and exercise should be the foundation for strategies to lower cholesterol, although statins and other cholesterol-lowering drugs can play an important role in overall cholesterol management. " In general, we don't think that patients should stop taking medications without talking to their physician. If a patient is experiencing side effects, the physician can often switch the patient to a different statin or other medicine that will continue to manage their cholesterol without the side effects, " said . Editors Note: In the last two weeks there have been an extraordinary number of medical articles on my web sites, about cholesterol lowering medications and possible side effects. I would personally encourage you to discuss this information with your own physician. I most certainly will be, at my next cardiologist and rheumatologist appointments. ************************************ Health News to Love: Chocolate Is Good for You By Reaney-Reuters - GLASGOW, Scotland (Sept. 3) Good news for chocoholics. The treat favored by millions not only tastes delicious but is healthy for you, American researchers said on Monday. Chocolate contains compounds called flavonoids that can help maintain a healthy heart and good circulation and reduce blood clotting -- which can cause heart attacks and strokes. " More and more, we are finding evidence that consumption of chocolate that is rich in flavonoids can have positive cardiovascular effects, " Carl Keen, a nutritionist at the University of California, , told a science conference. " We not only have observed an increase in antioxidant capacity after chocolate consumption, but also modulation of certain compounds which affect blood vessels. " Antioxidants are substances that help reduce the damage of cancer-causing charged particles in the body. Fruits, vegetables, nuts and whole grains are high in antioxidant vitamins such as C and E. NOT ALL CHOCOLATE CREATED EQUAL Flavonoids in chocolate are derived from cocoa, which is rich in the compounds. Research has shown that a small bar of dark chocolate contains as many flavonoids as six apples, 4.5 cups of tea, 28 glasses of white wine and two glasses of red. But Dr. Harold Schmitz said there were variations in the levels of flavonoids in chocolate and cocoa products depending on the production process, in which many flavonoids are destroyed. " All chocolates are not created equal in regards to flavonoid content, " Schmitz, a scientist with confectionery maker Mars Inc., told a news conference. Flavonoids are thought to reduce the risk of cardiovascular disease, the number one killer in many industrialized countries, by reducing platelet aggregation -- when blood platelets combine into a sticky mass and form clots. Keen and his colleagues measured the impact of chocolate on platelets in the blood in 25 volunteers. They presented their findings to the British Association for the Advancement of Science conference in Glasgow. The researchers collected blood samples from volunteers who ate 25 grams (0.9 ounces) of chocolate with a high flavonoid content and other volunteers who ate bread. They took blood samples from both groups two and six hours after they ate the chocolate and bread to measure their platelet activation. Volunteers who consumed the chocolate had lower levels of platelet activity, which would reduce the probability of having a blood clot. The scientists found no change in the group that ate the bread. Keen said the results of the study support earlier research showing that cocoa acts like low-dose aspirin which helps to reduce blood clotting. But he warned that eating chocolate should not be substituted for taking low dose aspirin because they work through different mechanism in the body. " These results lead us to believe that chocolate may contribute to a healthy, well-balanced diet, " Keen added. ************************** Thanks again, and please send your comments and suggestions.
