Statin Adverse Effects FAQ: ELDERLY AND STATINS
(The Cholesterol-lowering Statin Drug Names: Lipitor, Crestor, Mevacor, Pravachol, Zocor, Lescol, and Baycol, aka atorvastatin, rosuvastatin, cerivastatin, fluvastatin, lovastatin, pravastatin, and simvastatin; This class of drugs is also known as HMG-CoA Reductase Inhibitors, short for 3-Hydroxy-3-Methyl-Glutaryl Coenzyme A Reductase. ) To my physician, I believe that my symptoms may be due to the adverse effects a_ssociated with cholesterol-lowering statin drugs. I need your help to understand the cause of my symptoms, treatment options, and the prognosis for my recovery. Please review the references below, published medical studies that show similar problems a_ssociated with statin drugs. These are made available via the National Institutes of Health (NIH, http://www.ncbi.nlm.nih.gov/Entrez/) library of biomedical journal citations and other major repositories of medical research. Also, I am respectfully requesting that you file an adverse effects report with the FDA (http://www.fda.gov/medwatch/how.htm), and that you please send a copy of the report to the to the NIH-funded Statin Study, attention: Dr. Beatrice Golomb, Principal Investigator.

J Am Geriatr Soc. 2003 Jul;51(7):930-936. PMID: 12834512 "PARTICIPANTS: Four thousand nine hundred twenty-three Medicare beneficiaries from four states aged 65 and older" "CONCLUSION: Among elderly survivors of AMI, elevated total serum cholesterol measured postinfarction is not a_ssociated with an increased risk of all-cause mortality in the 6 years after discharge. Furthermore, this study found no evidence of an increased risk of all-cause mortality in patients with low total cholesterol. Further studies are needed to determine the relationship of postinfarction lipid subfractions and mortality in older patients with coronary artery disease (CAD)." Patients with Alzheimer's disease may be particularly susceptible to adverse effects of statins. Algotsson A, Winblad B. Dement Geriatr Cogn Disord. 2004;17(3):109-16. Epub 2004 Jan 20. Department of Clinical Neuroscience, Occupational Therapy and Elderly Care Research, Division of Geriatric Medicine, Karolinska Institute, Huddinge University Hospital, Huddinge, Sweden. In epidemiological, cross-sectional studies, treatment with 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) prevented to a large extent the development of Alzheimer's disease (AD), but the results of randomized, placebo-controlled studies, focused on statin therapy in patients with ischemic heart disease (IHD), are at variance. Nonetheless, data from epidemiological, longitudinal studies in humans as well as studies on transgenic mouse models and cultured neuronal cell lines indicate that cholesterol may contribute to the pathogenesis of AD. Statins have proven the****utic and preventive effects in IHD and other vascular diseases in man. They generally are well tolerated, but some adverse effects, probably due to antiproliferative and proapoptotic properties of the statins, are matters of concern. AD patients may be extrasusceptible to adverse effects of statins due to preexisting aberrations in signal transduction and energy metabolism in the neurons and a perturbed cholesterol metabolism in the brain. This problem might be addressed in randomized, double-blind studies with statins in AD. The statins differ from each other in several aspects, and they are not considered to be the****utically interchangeable. It could be fruitful to use both a placebo and two different types of statins, i.e. an essentially hydrophilic statin and a lipophilic statin, in a double-blinded fashion, and to compare the effects on the cognitive decline in AD.

Ray WA, Daugherty JR, Griffin MR. Inj Prev. 2002 Dec;8(4):276-9. Department of Preventive Medicine, Vanderbilt University School of Medicine and the Geriatric Research, Education and Clinical Center, Nashville VAMC, Nashville, Tennessee 37232, USA. wayne.ray@mcmail.vanderbilt.edu "CONTEXT: Three recent nested case-control studies conducted in automated databases suggest that users of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) have a risk of hip and other osteoporotic fractures half that of non-users of any lipid-lowering drug. However, this comparison may be biased by unmeasured factors a_ssociated with treated hyperlipidemias. OBJECTIVE: To compare the risk of hip fracture among users of statins and other lipid-lowering agents, which is less susceptible to bias than the comparisons performed in the previous studies. DESIGN AND SETTING: Retrospective cohort study conducted in the Tennessee Medicaid program between 1 January 1989 through 31 December 1998. SUBJECTS: New users of all lipid-lowering drugs and randomly selected non-user controls who at baseline were at least 50 years of age and did not have life threatening illness, nursing home residence, or diagnosed dementia or osteoporosis. There were 12506 persons with new use of statins, 4798 with new use of other lipid lowering drugs, and 17280 non-user controls. MAIN OUTCOME MEASURE: Fracture of the proximal femur (hip), excluding pathological fractures or those resulting from severe trauma. RESULTS: During 66690 person years of follow up, there were 186 hip fractures (2.8 per 1000). Relative to non-users, the adjusted incidence rate ratios (95% confidence interval) were 0.62 (0.45 to 0.85) for statin users and 0.44 (0.26 to 0.95) for other lipid-lowering drugs. When compared directly with the other drugs, the adjusted incidence rate ratio for statins was 1.42 (0.83-2.43). CONCLUSION: These data provide evidence that the previously observed protective effect of statins may be explained by unmeasured confounding factors.

University Department of Geriatric Medicine, Llandough Hospital, Penarth, UK. Cardiovascular disease is strongly age-related, and is the leading cause of death in older people. Several well-publicized trials have recently reported that statin drugs (HMG CoA reductase inhibitors) are effective in lowering cholesterol and in reducing the risk of myocardial infarction and stroke. In order to determine whether the results of these trials are relevant to our ageing population, we examined the representation of older people and women in randomized controlled trials of statin drugs. A systematic search of the medical literature from 1990 to 1999 was done to identify randomized placebo-controlled trials of statin drugs which evaluated clinical end-points-myocardial infarction, stroke or death. We identified 19 trials: 15 secondary prevention and four primary prevention. The mean age, age range and gender of the participants in these trials were determined. In the secondary prevention trials, the total number of patients randomized was 31683, with a combined mean age of 58.1 years. No trial enrolled people beyond the age of 75 years, and only 23% of the trial population was female. The four primary prevention trials randomized a combined total of 14 557 subjects with a mean age of 56.9 years. Only 10% of study participants were female. Statin drug trials have suffered from age and gender bias, having been mainly conducted in middle-aged male populations. The extrapolation of evidence from these trials to older people and women needs further evaluation.

Department of Neurology, Uniformed Services University of the Health Sciences, Bethesda, Maryland, USA. A patient developed an adult-onset dermatomyositis-like syndrome characterized by skin rash and progressive proximal muscle weakness concurrent with the intake of simvastatin. Despite discontinuation of the statin, symptoms progressed and required conventional steroid therapy for remission. The a_ssociation between statins and the development of a musculocutaneous syndrome closely resembling dermatomyositis in susceptible subjects is poorly understood and has been reported rarely. The purpose of this report is to provide additional support for this pathological a_ssociation. Since the population receiving statins is large and rapidly growing, caregivers are urged to be alert regarding the early recognition and proper care of the spectrum of neuromuscular complications linked to statin intake.
