Oxandrolone in the treatment of burn injuries: A systematic review and meta-analysis.

Abstract

BACKGROUND\nSevere burns induce a profound hypermetabolic response, leading to a prolonged state of catabolism associated with organ dysfunction and delay of wound healing. Oxandrolone, a synthetic testosterone analog, may alleviate the hypermetabolic catabolic state thereby decreasing associated morbidity. However, current literature has reported mixed outcomes on complications following Oxandrolone use, specifically liver and lung function. We conducted an updated systematic review and meta-analysis studying the effects of Oxandrolone on mortality, length of hospital stay, progressive liver dysfunction, and nine secondary outcomes.\n\n\nMETHODS\nWe searched Pubmed, EMBASE, Web of Science, CINAHL, and Cochrane Databases of Systematic Reviews and Randomized Controlled Trials. 31 Randomized control trials and observational studies were included. Basic science and animal studies were excluded. Only studies comparing Oxandrolone to standard of care, or placebo, were included.\n\n\nRESULTS\nOxandrolone did not affect rates of mortality (RR:0.72; 95% CI(0.47-1.08);p=0.11) or progressive liver dysfunction (RR:1.04; 95% CI(0.59-1.85);p=0.88), but did decrease length of stay in-hospital. Oxandrolone significantly increased weight re-gain, bone mineral density, percent lean body mass, and decreased wound healing time for donor graft sites. Oxandrolone did not change the incidence of transient liver dysfunction or mechanical ventilation requirements.\n\n\nCONCLUSIONS\nThere is evidence to suggest that Oxandrolone is a beneficial adjunct to the acute care of burn patients; shortening hospital stays and improving several growth and wound healing parameters. It does not appear that Oxandrolone increases the risk of progressive or transient liver injury, although monitoring liver enzymes is recommended.
