In the Understanding Potential Long-Term Impacts on Function with Tiotropium (UPLIFT) trial, tiotropium therapy for patients with chronic obstructive pulmonary disease (COPD) was associated with long-term improvements in lung function, quality of life, and COPD exacerbations. The therapy did not, however, significantly reduce the rate of decline in forced expiratory volume in 1 second (FEV1) compared with placebo.

The Long-Term Intervention on Fractures with Tibolone (LIFT) study demonstrated a reduced risk of vertebral fracture, breast cancer, and possibly colon cancer but a significantly increased risk of stroke in older postmenopausal women treated with tibolone versus those treated with placebo.

A systematic search of the literature published in the International Journal of Clinical Practice demonstrated that angiotensin receptor blockers (ARBs) used as monotherapy or in combination with angiotensin-converting enzyme (ACE) inhibitors are not associated with a beneficial effect on mortality in patients with heart failure (HF).

Primary androgen deprivation therapy (PADT), the second most common treatment for localized prostate cancer following prostatectomy, is no more effective than conservative medical management for prolonging survival in most older patients with prostate cancer.

A recent multinational, randomized, double-blind, placebo-controlled clinical trial demonstrated that administration of aliskiren provides additional renal protection to patients with hypertension, type 2 diabetes mellitus, and nephropathy who are already receiving optimal antihypertensive therapy and renal protective therapy with the angiotensin receptor blocker (ARB) losartan.

The first phase of a double-blind, randomized, parallel-group, multicenter, outpatient study demonstrated that treatment with the combination of etanercept and methotrexate was more effective in inducing both clinical remission and radiographic nonprogression than methotrexate alone in patients with early moderate-to-severe rheumatoid arthritis (RA).

In a nested, case-control study published in the Archives of General Psychiatry, investigators observed that the use of selective serotonin-reuptake inhibitors (SSRIs) increased the risk of upper gastrointestinal (GI) tract bleeding; this increased risk was also observed with the serotonin and norepinephrine reuptake inhibitor (SNRI) venlafaxine. This risk may be increased when the agents are used concomitantly with nonsteroidal anti-inflammatory drugs (NSAIDs) and decreased when used concomitantly with acid-suppressing agents.

Two randomized, double-blind, phase 3 clinical trials demonstrated that raltegravir plus optimized background therapy was more effective than optimized background therapy alone in suppressing resistant HIV-1.

According to the results of an extended follow-up of the African American Study of Kidney Disease and Hypertension (AASK), long-term reduction of blood pressure to a lower goal than the standard demonstrates no significant effect on the progression of chronic kidney disease (CKD) in nondiabetic hypertensive patients, except in patients with baseline urinary protein/creatinine ratio >0.22, said Jackson Wright, MD, professor of medicine and director of the hypertension program at Case Western Reserve University, Cleveland. These results were presented at the 23rd Annual Scientific Meeting of the American Society of Hypertension, New Orleans, May 14–17, 2008.
