Statins touted for persons with normal cholesterol levels

Monday, November 24th, 2008

Front-page headlines worldwide announced the “stunning” results of a trial of rosuvastatin (Crestor) in “apparently healthy men and women” with an LDL-cholesterol less than 130 mg/dL (3.4 mmol/L). Serious heart problems were reportedly reduced by about 50%.

“This takes prevention to a whole new level,” said Dr. W. Douglas Weaver, President of the American College of Cardiology (Washington Post 11/10/08).

The trial, called JUPITER (Justification for the Use of Statins in Prevention: an Intervention Trial Evaluating Rosuvastatin) was financially supported by AstraZeneca, the manufacturer of Crestor. It is not stated whether the trial was named before or after data were accumulated. The primary author, Paul Ridker, also is listed as a coinventor on patents for the use of inflammatory biomarkers, including the use of high sensitivity C-reactive protein (HS-CRP) in the evaluation of risk for cardiovascular disease.

The 17,802 subjects in the trial had an elevated HS-CRP of 2.0 mg/L or higher (Ridker PM, et al., N Engl J Med 2008;359:2195-2207).

Until Nov 26, the New England Journal of Medicine is inviting comments on whether this article will change your practice.

As the accompanying editorial noted, the absolute risk reduction was low. The number (percent) of “hard” outcomes (myocardial infarction, stroke, or death from cardiovascular causes) was reduced from 157 (1.8%) in the placebo to 83 (0.9%) in the rosuvastatin group. The number needed to treat was 120. The cost of the drug is $3.45 per day (or nearly $300,000 to prevent one adverse event).

Note that the trial evaluated statins, not HS-CRP testing. It did not compare subjects with and without high HS-CRP, nor compare the usefulness of HS-CRP with other risk factors (ibid.).

On the adverse side of the balance, subjects in the rosuvastatin group had significantly higher glycosylated hemoglobin levels and incidence of diabetes mellitus (3.0% vs. 2.4%) (ibid.) The trial was discontinued three years early, after only 1.9 years, thus cutting off the discovery of potential long-term adverse effects.

While not yet statistically significant, the rosuvastatin group had more muscle weakness and pain and more elevations in laboratory values indicating possible kidney or liver damage. One case of nonfatal rhabdomyolysis was reported in a rosuvastatin recipient after the trial was suspended. During a 4-week run-in period, anyone exhibiting compliance problems or adverse reactions could be screened out; 1,521 subjects were excluded during this period, in addition to the nearly 57,000 eliminated at the outset. Compliance rates during the trial were unusually low, with nearly 15% of the participants stopping their pills during each year, noted Sandy Szwarc, B.S.N., R.N.

What the JUPITER study really shows, remarks Duane Graveline, M.D., M.P.H., is that statins work by reducing inflammation, not by reducing cholesterol. This effect requires much lower doses, which have fewer side effects.

While rates of hospitalization for coronary heart disease have shown decreases since the mid-1980s, the rate for congestive heart failure has increased continually since 1980. From 2002-2006, the relative risk of hospitalization for heart failure was 1.37 times the rate in 1980-1984, according to research presented at the American Heart Association’s 2008 scientific session (Medical News Today 11/12/08).

Universal care striking out in “laboratories of democracy”

Thursday, November 20th, 2008

Hawaii is ending the only state universal child health-care program in the country, after just 7 months.

The Keiki (Child) Care Plan was designed to offer health care insurance to the children of parents who earn too much to qualify for Medicaid or Hawaii’s State Children’s Health Insurance Program (SCHIP), but are felt not to be able to afford private coverage.

State officials found that families were dropping private coverage in order to enroll their children in the “free” plan In fact 85 percent of the children in Keiki Care were previously in a private, nonprofit plan costing $55 per month. Facing budgetary shortfalls, Governor Linda Lingle pulled the plug on funding.

“All this is a lesson for political leaders in Washington who are drafting plans now to expand SCHIP to children in families earning up to $82,000 a year or more. That expansion would wind up doing what Keiki Care did: mainly crowd out the private coverage that millions of middle-income kids already have,” writes Grace-Marie Turner (NY Post 10/27/08).

According to MIT economist Jonathan Gruber, SCHIP crowds out private insurance 60 percent of the time. California, Pennsylvania, Illinois, and Wisconsin have turned back from major efforts to approach universal coverage because of the prohibitive cost. Massachusetts officials no longer claim that such a goal is even possible, Turner writes.

Two Massachusetts safety-net hospitals, Boston Medical Center and Cambridge Health Alliance, will be cutting programs because of state cuts of more than $200 million in payments to Medicaid providers (Boston Globe 10/17/08).

Designed to cover 3,500 children, Keiki Care was a small-scale program. Fiscal problems were evident when only 2,000 children had enrolled. Larger programs lead to fiscal disaster (Investors Business Daily 10/20/08).

Tennessee’s disastrous experiment with universal coverage “forced dozens of hospitals out of business, pushed thousands of doctors and other health care professionals out of the state, destroyed any semblance of competitive health insurance market, and nearly drove the state government into bankruptcy,” writes Patrick Poole (American Thinker 1/17/07).

The state budget was in such straits that a state income tax was proposed, precipitating the Tennessee Tax Revolt of 2000. Thousands of citizens swarmed into downtown Nashville, and traffic came to a virtual standstill, as cars blared their horns from 7:30 a.m. well into the night. Legislators abandoned the income tax proposal and fled. Poole described it as the “most exhilarating experience I have been privileged to…witness….” Democrat Gov. Phil Bredesen was forced to dismantle TennCare piecemeal.

People like Gov. Arnold Schwarzenegger, who proposed to inflict state health insurance on all residents of California, including illegal aliens, should go to Tennessee if they need a heart valve replaced, suggests Poole, to see first-hand the results of universal health care.

Perioperative beta blockers associated with more heart attacks

Tuesday, November 18th, 2008

The 30-day myocardial infarction and mortality rate was significantly higher (2.74% v. 0.7%) in patients who got beta blockers in conjunction with noncardiac surgery, according to an article in the October 2008 issue of Archives of Surgery (Kaafarani HMA. Arch Surg 2008;143:940-944).

This paper adds to the finding of the POISE study (Perioperative Ischemic Evaluation Trial) of more than 8,000 patients undergoing noncardiac surgery, which was published in the May issue of the Lancet. Although there were fewer MIs in the group receiving extended-release metoprolol, all-cause mortality and disabling strokes were significantly more likely in that group (MedScape 10/29/08).

The authors’ interpretation was: “Our results highlight the risk in assuming a perioperative beta-blocker regimen has benefit without substantial harm, and the importance and need for large randomised trials in the perioperative setting. Patients are unlikely to accept the risks associated with perioperative extended-release metoprolol” (Lancet 2008: 71:1839-1847).

AAPS President Mark Kellen, M.D., comments that these studies illustrate the danger of centralized control of medicine, with instant reporting to bureacurats through electronic records and pay for “performance” (meaning compliance with “guidelines”).

“In a system where physicians are independent clinicians paid by patients and not third parties, information is slowly incorporated into our practices, putting only a few patients at a time at risk of complications from new medicines and procedures,” he states.

In contrast, “national guidelines can easily be prone to overtreatment, given the bias for publishing favorable studies about a drug or treatment over negative studies or studies showing harm. Immense amounts of money can change hands with the recommendation to use a certain treatment.”

With centralized control, decisions about the “standard of care” could be implemented in a very short time, with potentially disastrous results for millions of patients.

Psychotropic prescriptions for children soar; conflicts of interest, informed consent under scrutiny

Monday, November 10th, 2008

A series of articles in the Dallas Morning News focuses on alleged financial conflicts of interest of psychiatrists involved in the Children’s Medication Algorithm Project (CMAP). The CMAP protocol has been “quietly shelved” after objections were raised by Texas Attorney General Greg Abbott.

The state of Texas is suing a pharmaceutical company that allegedly used false advertising and improper influence to get its products on the now-mandatory adult protocol, the Texas Medication Algorithm Project (TMAP).

The newer drugs chosen for the protocol are ten times as expensive than traditional drugs, but have no substantial advantage, according to a report by the National Institute of Mental Health.

Sen. Charles Grassley (R-IA) stated that three Harvard experts whose research contributed to an explosion of antipsychotic drug use in children failed to report a combined $3.2 million in company consulting fees, in violation of Harvard’s rules.

Dr. Graham Emslie of University of Texas Southwestern, on the other hand, said he had never witnessed improper drug company influence in CMAP research.

Without the protocol, CMAP advocates warn that Texas children will be treated by individual doctors who have “their own personal influences” (Emily Ramshaw, Dallas Morning News 8/18/08).

Controversy about promotion of psychotropics in children is breaking out in other states also. New Jersey state assemblyman Michael Coherty wrote to the state department of health on Aug 20, asking about the policy that permited the NJ Medicaid program to spend $73 million between 2000 and 2007 on antipsychotic drugs for children under the age of 18 although the drugs are not FDA approved for pediatric use. Lawsuits are pending in several states (Pharmalot.com 9/3/08).

Issues include improper marketing and failure to disclose serious side effects, which prompted state programs to overpay for olanzapine (Zyprexa), quetiapine (Seroquel), and risperidone (Risperdal).

While slightly fewer people stopped taking atypical antipsychotics Zyprexa and Seroquel because of tremors, compared with older drugs, the new drugs allegedly gave some of them diabetes. (St. Petersburg Times 4/12/08).

Particularly in children, it is not just the drugs prescribed, but the diagnoses that are in question. Six million children have been diagnosed with serious psychiatric disorders warranting drug treatment—1 million with bipolar disorder, long believed to occur only in adults (PBS Frontline, The Medicated Child).

Many children are being identified as potential recipients of psychotropic drugs through government-supported, school-based mental health “screening.” Is this uncovering a vast, previously unrecognized epidemic, as Richard Friedman, M.D., of the Psychopharmacology Clinic at Weill Cornell Medical School, holds (N Engl J Med 2006;355:2717-2719)?

The predictive value of a positive test in the Columbia University TeenScreen program is 16%, although it “demonstrated good sensitivity and reasonable specificity identifying students at risk for suicide,” according to its author (Schaffer D et al., J Am Acad Child Adolesc Psychiatry 2004;43:71-79).

A federal court has given the green light to a civil rights lawsuit filed on behalf of Chelsea Rhoades, who was subjected to TeenScreen without parental consent, and, like a majority of her classmates, was told she suffered from mental health problems.

A BBC All in the Mind radio commentary, which covers the Rhoades case and issues related to screening, is available online.

One ethical concern raised in Texas is the use of psychotropic drugs in children who are in foster care.
