Preventive aspirin reasonable for diabetics at high risk, not low
Guidance on how to use aspirin for primary prevention of cardiovascular events in diabetics was offered in a recent statement from the American Diabetes Association, the American Heart Association and the American College of Cardiology Foundation.
Aspirin use provides a modest (about 10%) reduction in cardiovascular events overall, but its effect as primary prevention in diabetics is unclear, the experts concluded after an evidence review. However, itís reasonable to use low-dose (75 to 162 mg/d) aspirin as prevention in diabetics who have an increased risk of cardiovascular disease (a 10-year risk over 10%), the statement said. That would include most men over 50 and women over 60 who have one or more additional risk factors: smoking, hypertension, dyslipidemia, family history of premature cardiovascular disease or albuminuria.
For patients at intermediate risk (younger patients with one or more of the risk factors, older patients with no risk factors, or anyone with a 10-year risk of 5% to 10%), preventive aspirin might be considered, the experts said. However, patients at low risk (those with a 10-year risk under 5%) should not be advised to take aspirin, as the potential adverse effects from bleeding offset the potential benefits. The statement noted that patients with diabetes are at higher risk for adverse events from aspirin than nondiabetics.
When calculating a patientís risk of cardiovascular disease, physicians should also consider the beneficial effects of other treatments such as statins, blood pressure control and smoking cessation. If these other treatments are adopted first, then there may be less need for aspirin, the statement said. The statement concluded by calling for additional research to better define the effects of aspirin in diabetes, including any sex-specific differences. The statement was published online by Circulation on May 27..
Education effort increased thiazide use
An effort to disseminate evidence-based information on thiazide-type diuretics resulted in a small increase in the use of the medications, a new study found.
Between 2004 and 2007, more than 100 investigator-educators met with more than 18,000 physicians in different parts of the country to educate them about the results of ALLHAT (Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial), which supported the use of thiazides as first-line therapy for hypertension. This study compared use of the drugs in counties where the investigator-educators had been active with use in areas where they hadnít. The results were published in the May 24 Archives of Internal Medicine.
According to a survey of physicians, the percentage of hypertension visits in which the drugs were recorded went up the most in areas where the educators were most active: an increase of 8.6% in active counties compared to 2% or lower increases in other areas. Pharmacy dispensing data showed a similar trend. Thiazide prescriptions went up 8.7% in active counties compared to 3.9% in inactive ones.
Study authors noted that the effect of the program was small, but consistent with the small dose of the intervention that physicians received. In addition, the project had to compete with public questioning of the ALLHAT findings by the pharmaceutical industry and others. Still, they concluded that such efforts, which they described as academic detailing, have the potential to improve prescribing patterns.
Although he praised the effort in an accompanying commentary, Jerry Avorn, MD, noted that it was not actually academic detailing, a concept which he invented. Academic detailing typically involves a one-to-one encounter like that of a pharmaceutical rep visiting a physician, while the ALLHAT dissemination program used group presentations. The difference was probably a major contributor to the projectís small effect, Dr. Avorn noted. More work is needed on how to develop delivery systems for getting evidence-based data into clinical practice, he concluded.
MKSAP Quiz: lower-extremity pain and 'red knots'
A 25-year-old woman is evaluated for a 2-week history of bilateral lower-extremity pain and skin lesions that she describes as ďred knots.Ē Ibuprofen has not alleviated her discomfort, and she has continued to develop new skin lesions. Six months ago, she developed vulvar ulcers that were negative for herpes simplex virus on a polymerase chain reaction assay; these lesions healed within 3 weeks. Two years ago, she developed uveitis that was treated with prednisolone drops. She also has a 7-year history of Raynaud phenomenon and a long-standing history of recurrent oral ulcers. She has had no recent infections and currently has no vulvar ulcers.
On physical examination, vital signs and cardiopulmonary and abdominal examinations are normal. There is no conjunctival injection. There are two ulcers on her tongue. Cutaneous examination reveals several subcutaneous reddish-colored nodules that are tender to palpation located on the lower extremities bilaterally. There is no synovitis, and range of motion of all joints is full.
|Complete blood count||Normal|
|Erythrocyte sedimentation rate||95 mm/h|
A chest radiograph is normal.

Beta-blockers may have benefit in COPD patients
Beta-blockers may help reduce exacerbation risk and improve survival in patients with chronic obstructive pulmonary disease (COPD), according to a new study.
Physicians often avoid beta-blockers in COPD patients with cardiovascular disease because of potential pulmonary complications. However, some research has indicated that beta-blockers may in fact be helpful in this population. To further examine this question, researchers performed an observational cohort study of data from 23 Dutch general medicine practices. The goal of the study, which appeared in the May 24 Archives of Internal Medicine, was to determine whether long-term use of beta-blockers improves outcomes in COPD patients with and without cardiovascular disease.
A total of 2,230 patients who had prevalent COPD at the start of the study (25%) or were diagnosed with incident COPD during follow-up (75%) were included. Fifty-three percent of patients were men, and the mean age at the beginning of the study was 64.8 years. Six hundred eighty-six patients (30.8%) died and 1,055 (47.3%) had one or more COPD exacerbations over a mean of 7.2 years of follow-up. Overall crude and adjusted hazard ratios with beta-blocker use, respectively, were 0.70 (95% CI, 0.59 to 0.84) and 0.68 (95% CI, 0.56 to 0.83) for mortality and 0.73 (95% CI, 0.63 to 0.83) and 0.71 (95% CI, 0.60 to 0.83) for exacerbations. Results were similar in patients with COPD but no evident cardiovascular disease.
The authors noted that COPD could have been incorrectly diagnosed in some study patients who actually had cardiovascular disease, among other limitations. However, they concluded that beta-blockers may reduce mortality rates and COPD exacerbations in patients with both COPD and cardiovascular disease. An accompanying editorial emphasized the need for a randomized, controlled trial to confirm the findings but said that the current study "provide[s] a rationale for the practicing clinicians to use Ŗ-blockers (even noncardioselective ones such as carvedilol) cautiously in their patients with COPD who also have a coexisting cardiovascular condition for which a Ŗ-blocker is required."
SSRIs linked to cataract development
Researchers found a possible association between current use of selective serotonin reuptake inhibitors (SSRIs), especially fluvoxamine and venlafaxine, and a future diagnosis of cataracts.
Researchers conducted a nested, case-control study of subjects within a previous study of patients who had received a coronary revascularization procedure between 1995 through 2004 in Quebec, Canada. Linked administrative databases of the health insurance system provided the data for all residents 65 years or older who are part of Canada's universal health care plan. Results appeared in the June issue of Ophthalmology.
Available SSRIs included citalopram, fluoxetine, fluvoxamine, paroxetine, and sertraline, and researchers also looked at venlafaxine, a serotonin and norepinephrine reuptake inhibitor (SNRI). Researchers identified patients prescribed SSRIs or venlafaxine one year before the index date. Current users had received an SSRI or venlafaxine within 30 days of the index date, or were defined as past users. Cataracts were identified by an ophthalmologist.
For each case, 10 controls were selected and matched by index date, age and cohort entry. Crude and adjusted rate ratios (RRs) and corresponding confidence intervals (CIs) were computed for current SSRI use. Rate ratios were adjusted for gender, corticosteroid use, statins, high blood pressure, antihypertensives and antidiabetics.
From the data, 18,784 cases and 187,840 controls met inclusion criteria. The adjusted RR for cataracts among current users of SSRIs was 1.15 (95% CI, 1.08 to 1.23). The risk of cataracts was highest with fluvoxamine (RR, 1.39; 95% CI, 1.07 to 1.80), followed by venlafaxine (RR, 1.33; 95% CI, 1.14 to 1.55) and paroxetine for cataract surgery (RR, 1.23; 95% CI, 1.05 to 1.45).
The average time to diagnosis of cataracts while on SSRI therapy was 656 days for the first analysis and 690 days for a second analysis. The two analyses were generally concordant, except when cases were restricted to outpatient surgery. Then, paroxetine was associated with cataracts (RR, 1.23; 95% CI, 1.05 to 1.45). Past use did not pose a risk (RR, 1.06; 95% CI, 0.97 to 1.17).
The strength of this study is the large sample size and the detailed prescription drug information, which allowed researchers to look at the time of onset of cataracts, as well as the risk of individual SSRIs. Limitations include cataract diagnosis by ICD-9 codes, which does not confirm surgery. Detailed work-ups for cataract diagnosis were not available. Not all confounders, including smoking, could be assessed. Finally, because cataracts may take years to develop, subjects could have had undiagnosed cataracts.
Up to 10% of U.S. residents take an antidepressant, mainly SSRIs and SNRIs. Using a relative risk of 1.15 for SSRI users, a population attributable risk of 1.5%, and a 10% prevalence of use, researchers estimated 22,000 cases of cataracts may be avoided secondary to SSRI use. However, more study is needed to confirm the link in other populations, authors wrote.
Hormone replacement therapy.
Route of HRT administration may affect stroke risk
Risk for stroke may be lower with transdermal versus oral hormone replacement therapy (HRT) in postmenopausal women, according to a new study.
Canadian and German researchers performed a population-based, nested case-control study to determine whether route of HRT administration affected stroke risk in postmenopausal women. Data from approximately 400 general practices in the United Kingdom reporting to the General Practice Research Database were examined. Women who were 50 to 79 years of age between Jan. 1, 1987 and Oct. 31, 2006 were included. HRT exposure was classified as estrogens only, estrogens plus progestogen, progestogen only, and tibolone. Estrogens were further classified by oral or transdermal route of administration and high or low dose. The study's main outcome measures were rate ratio of stroke with current oral and transdermal HRT use versus no use. Results were published online June 4 by BMJ.
Overall, 15,710 stroke cases were matched to 59,958 controls over the study period. One thousand two hundred fourteen cases (7.7%) and 4,124 controls (6.9%) received at least one HRT prescription in the year preceding the index date (i.e., the date of the first recorded stroke). The adjusted rate ratio of stroke associated with current transdermal HRT use was 0.95 (95% CI, 0.75 to 1.20) compared with no use. Patches with low estrogen doses did not increase stroke risk compared with no use, while patches with high estrogen doses did (rate ratio, 0.81 [95% CI, 0.62 to 1.05] vs. 1.89 [95% CI, 1.15 to 3.11]). Stroke rate was higher in current low- and high-dose HRT users than in nonusers (rate ratio, 1.28 [95% CI, 1.15 to 1.42]).
The data used in the study were not validated by chart review, and the authors were unable to distinguish between ischemic and hemorrhagic stroke, among other limitations. However, the authors concluded that transdermal HRT with low doses of estrogen does not appear to increase stroke risk among postmenopausal women.
"Although these results alone do not represent definitive evidence to promote the use of the transdermal route over oral administration of oestrogen replacement therapy, this study should encourage further research on the importance of the route of administration to define the role of transdermal oestrogens in the therapeutic arsenal for the treatment of menopausal symptoms," the authors wrote.
PPIs get warning on fracture risk
High doses or long-term use of proton-pump inhibitors may increase the risk of certain fractures, the FDA recently warned health care professionals and patients.
The labeling of both prescription and over-the-counter PPIs will be revised to reflect this risk, according to an FDA news release. The warning is based on an FDA review of several epidemiological studies that reported an increased risk of fractures of the hip, wrist and spine in patients using PPIs.
Physicians should weigh the known benefits against the potential risks of proton-pump inhibitors when determining if these medications are appropriate for treatment, the FDA advised. ďWhen prescribing proton-pump inhibitors, health care professionals should consider whether a lower dose or shorter duration of therapy would adequately treat the patient's condition,Ē said an FDA official.
Any side effects or other product problems with PPIs should be reported via the FDAís MedWatch Adverse Event Reporting program or by calling 800-332-1088..
Liver injuries found in patients on orlistat
Cases of severe liver injury with hepatocellular necrosis or acute hepatic failure have been reported in patients taking the weight-loss medication orlistat, the FDA recently announced.
Warnings will be added to the labeling for Xenical (the 120-mg prescription form of orlistat) and Alli (60 mg, available over the counter). The injuries have been reported only rarely (12 foreign reports with Xenical and 1 U.S. report with Alli) and a cause-and-effect relationship has not been established, according to an FDA news release. However, because of the seriousness of severe liver injury, the FDA added information to the labels to educate the public.
Prescribing physicians should weigh the benefits of weight loss against the potential risks when determining if these medications are appropriate for patients and instruct patients to report any symptoms of hepatic dysfunction (anorexia, pruritus, jaundice, dark urine, light colored stools, or right upper quadrant pain) when using these medications. If liver injury is suspected, orlistat and other suspect medications should be discontinued immediately and liver function tests and ALT and AST levels obtained. Any adverse events associated with the medications should be reported to FDA's MedWatch program.

This patientís lower-extremity lesions are consistent with erythema nodosum. She also has oral ulcers, an elevated erythrocyte sedimentation rate, and a history of genital mucosal ulcers and uveitis. This clinical presentation strongly suggests a diagnosis of BehÁet disease, and the most appropriate management for this patient is prednisone.
Diagnostic criteria for BehÁet disease consist of the presence of oral ulcerations that recur at least three times in 1 year and at least two of the following manifestations: recurrent genital ulcerations, inflammatory eye disease, cutaneous lesions, and positive results on a pathergy test (characterized by a papule developing 48 hours after insertion of a 20-gauge needle intradermally). Patients with BehÁet disease also may have central nervous system vasculitis; a nonerosive arthritis that involves the medium and large joints; and elevated markers of inflammation, such as the erythrocyte sedimentation rate. Other manifestations include arterial and venous thromboses, and patients with BehÁet disease have a high mortality rate associated with arterial aneurysm rupture.
Treatment of BehÁet disease is directed toward the involved organ system. Although erythema nodosum can be treated with NSAIDs, use of these agents has not alleviated this patientís symptoms. Treatment with a corticosteroid such as prednisone is therefore reasonable.
Leflunomide and sulfasalazine are indicated to treat rheumatoid arthritis but are not useful in patients with erythema nodosum or BehÁet disease. Rheumatoid arthritis may present with Raynaud phenomenon and subcutaneous nodules. However, rheumatoid nodules typically develop on pressure points and are not tender or erythematous. Rheumatoid arthritis also is characterized by swelling and tenderness in and around the joints and may manifest as joint stiffness, synovial hypertrophy, synovitis, joint effusion, and loss of normal range of motion. These findings are absent in this patient.
Sulfasalazine also is used to treat inflammatory bowel disease, which may be associated with erythema nodosum. However, this patient has no gastrointestinal manifestations.
