Multimodal nutrition/anabolic therapy for wasting conditions.

ABSTRACT

PURPOSE OF REVIEW Significant progress has been made in the field of defining and describing the pathophysiology of wasting conditions such as cachexia. The number of new promising drugs, nutritional therapy alternatives, and exercise/rehabilitation programs is increasing. The purpose of this review is to give an overview of recent clinical findings from intervention studies investigating multimodal anabolic therapies utilizing drug, nutritional, and/or exercise interventions in order to counteract wasting. RECENT FINDINGS: Anabolic agents such as ghrelin and selective androgen receptor modulators are under late-phase clinical testing and hold promise as new therapies, and their ability to mitigate weight loss and improve muscle mass and physical function is evaluated. In the past 2 years, eight new studies investigating interventions with anabolic potential in wasting have been published, among which three of these studies were multimodal. SUMMARY: Targeted anabolic therapies aiming to prevent or reverse wasting might involve a combination of anabolic pharmacologic drugs, nutrition, and physical exercise working concurrently to enhance muscle protein synthesis and reduce breakdown. Some anabolic pharmacological interventions demonstrate the potential to improve muscle mass, but the multimodal interventions seem in greater extent to also demonstrate improvement in physical function.
