SWITCHING MEDICATIONS, ADDING PSYCHOTHERAPY MAY HELP TEENS WHOSE INITIAL MEDICATION FOR DEPRESSION IS INEFFECTIVE
CHICAGOFor adolescents with depression not responding to an initial treatment with a selective serotonin reuptake inhibitor (SSRI; a class of antidepressant drugs), switching medications and adding cognitive behavioral therapy resulted in an improvement in symptoms, compared to just changing medications, according to a study in the February 27 issue of JAMA.
Adolescent depression is a common, chronic, recurrent and impairing condition. "Untreated depression results in impairment in school, interpersonal relationships, occupational adjustment, and increases the risk for suicidal behavior and completed suicide. Therefore, the proper treatment of adolescent depression has profound public health implications for youth in this critical stage of development," the researchers write.
Clinical guidelines for the treatment of adolescent depression recommend the prescribing of SSRI medications, psychotherapy, or both. While these treatments alone or in combination have been shown to be effective, at least 40 percent of adolescents with depression do not show an adequate clinical response to these interventions.
David Brent, M.D., of the University of Pittsburgh, and colleagues examined the relative efficacy of medication type, cognitive behavioral therapy (CBT), and the combination of both for the treatment of resistant adolescent depression. The randomized controlled trial, conducted from 2000-2006, included 334 patients, age 12 to 18 years, with a primary diagnosis of major depressive disorder who had not responded to a two-month initial treatment with an SSRI. For 12 weeks, participants were randomized to one of four treatments: switch to a second, different SSRI (paroxetine, citalopram, or fluoxetine); switch to a different SSRI plus CBT; switch to venlafaxine (a selective serotonin and noradrenergic reuptake inhibitor [SNRI], an antidepressant shown in some studies to be superior to an SSRI in the management of treatment-resistant adult depression); switch to venlafaxine plus CBT.
"In this study of adolescents with moderately severe and chronic depression who had not responded to an adequate course of treatment with an SSRI antidepressant, switching to a combination of CBT and another antidepressant resulted in a higher rate of clinical response [54.8 percent] than switching to another medication without CBT [40.5 percent]. There was no differential effect between switching to another SSRI [47.0 percent] or to venlafaxine [48.2 percent]," the authors write.
There were also no differential treatment effects on change in self-rated depressive symptoms, suicidal ideation, or on the rate of harm-related or other adverse events. There was a greater increase in diastolic blood pressure and pulse and more frequent occurrence of skin problems during venlafaxine than SSRI treatment.
"...the clinician should convey hope to the adolescent with depression and his or her family that, despite a first unsuccessful treatment for depression, persistence with additional appropriate interventions can result in substantial clinical improvement," the researchers conclude.

USE OF ADULT STEM CELLS MAY BE BENEFICIAL FOR SOME PATIENTS WITH CERTAIN CARDIOVASCULAR DISORDERS AND AUTOIMMUNE DISEASES
CHICAGOA review of previously published research suggests that stem cells harvested from an adult’s blood or marrow may provide treatment benefit to select patients for some autoimmune diseases and cardiovascular disorders, according to an article in the February 27 issue of JAMA.
In broad terms, there are two types of stem cells, embryonic stem cells and adult stem cells. Human embryonic stem cells are isolated from a 4- to 5-day-old postfertilization blastocyst (an early form in the development of an embryo). Adult stem cells are located in tissues throughout the body and function as a reservoir to replace damaged or aging cells. Stem cell therapy is rapidly developing and shows great promise, "but clinical application has lagged due to ethical concerns or difficulties in harvesting or safely and efficiently expanding sufficient quantities. In contrast, clinical indications for blood-derived (from peripheral or umbilical cord blood) and bone marrow-derived stem cells, which can be easily and safely harvested, are rapidly increasing," the authors write.
Richard K. Burt, M.D., of the Northwestern University Feinberg School of Medicine, Chicago, and colleagues conducted a review of articles regarding clinical indications and outcomes for use of blood- and bone marrow-derived stem cells. A search of databases identified 323 reports that were examined for feasibility and toxicity, and 69 that were evaluated for outcomes. These studies were published between January 1997 and December 2007.
For autoimmune diseases, 26 reports representing 854 patients reported treatment-related mortality of less than one percent (2/220 patients) for nonmyeloablative (not causing bone marrow suppression), less than two percent (3/197) for dose-reduced myeloablative, and 13 percent (13/100) for intense myeloablative regimens, i.e., those including total body irradiation or high-dose busulfan (a drug used in the treatment of some types of chronic leukemia).
"While all trials performed during the inflammatory stage of autoimmune disease suggested that transplantation of hematopoietic [formation of blood or blood cells] stem cells (HSCs) may have a potent disease-remitting effect, remission duration remains unclear, and no randomized trials have been published," the researchers write.
For reports involving cardiovascular diseases, including 17 reports involving 1,002 heart attack patients, 16 reports involving 493 patients with chronic coronary artery disease, and three meta-analyses, the evidence suggested that stem cell transplantation performed in patients with coronary artery disease may contribute to modest improvement in cardiac function.
"Stem cells harvested from blood or marrow, whether administered as purified HSCs or mesenchymal [cells that develop into connective tissue, blood vessels and lymphatic tissue] stem cells or as an unmanipulated or unpurified product can, under appropriate conditions in select patients, provide disease-ameliorating effects in some autoimmune diseases and cardiovascular disorders. Clinical trials are needed to determine the most appropriate cell type, dose, method, timing of delivery, and adverse effects of adult HSCs for these and other nonmalignant disorders," the authors conclude.

AGENTS USED FOR TREATMENT OF ANEMIA ASSOCIATED WITH INCREASED RISK OF BLOOD CLOTS, DEATH IN PATIENTS WITH CANCER
CHICAGOTreating anemia with a class of drugs known as erythropoiesis-stimulating agents (ESAs) is associated with an increased risk of venous thromboembolism (blood clots in the deep veins of the legs or in the lungs) and death among patients with cancer, according to an article in the February 27 issue of JAMA.
The ESAs erythropoietin and darbepoetin are widely used to treat anemia in patients with cancer. Some studies have indicated that there may be a higher risk of venous thromboembolism (VTE) with these medications, but it has not been known if there is an associated increased risk of death, according to background information in the article.
Charles L. Bennett, M.D., Ph.D., of the Northwestern University Feinberg School of Medicine, Chicago, and colleagues examined the rate of VTE and death associated with ESA administration for treatment of anemia among patients with cancer by conducting a review of phase 3 trials.
The researchers identified 51 clinical trials with 13,611 patients to examine survival. Analysis of the data indicated that the risk of death was significantly higher for patients with cancer who were treated with ESA vs. the control (placebo) group.
Venous thromboembolism was evaluated for 38 trials that included 8,172 patients. The researchers found that there was a significantly increased risk (57 percent) of VTE among patients treated with ESA (334 events among 4,610 patients treated with ESA vs. 173 events among 3,562 control patients).
"These risks are important given the prevalence of ESA use as a supportive care drug among patients with cancer as well as the dissemination of a series of safety advisories by the Food and Drug Administration (FDA) and ESA manufacturers," the authors write.
"Safety concerns account in large part for changes observed in patterns of use, reimbursement policies, clinical guidelines, and FDA-approved package inserts pertaining to ESAs in the oncology setting. Our findings, in conjunction with basic science reports on erythropoietin and erythropoietin receptors in solid cancers, raise concern about ESA safety for patients with cancer."

ADULT STEM CELLS ARE HELPING PATIENTS WITH AUTOIMMUNE DISEASES AND CARDIOVASCULAR DISORDERS
INTRO:
Adult stem cell therapy has become a standard of care when treating several types of cancer. Now a review of clinical trials involving adult stem cells during the past ten years indicates they are helping patients who have a variety of diseases and even heart trouble. One patient diagnosed with multiple sclerosis says his symptoms are gone. Jennifer Mitchell explains in this week’s JAMA Report.
