Incidence of oxandrolone induced hepatic transaminitis in patients with burn injury

A Reappraisal of Oxandrolone in Burn Management

Objective: Burn injuries remain among the most severe traumatic injuries globally. With the discovery of cortisol, the use of steroids has become an essential therapy for the management of inflammatory and metabolic conditions. Several studies have shown the steroid oxandrolone improves burn injuries through stimulating anabolic and reducing catabolic processes. In this review, we examine the efficacy and applications of oxandrolone with regard to burn management and treatment. Data Sources: A literature search was performed using the PubMed database from January 1990 to May 2020 to identify articles on oxandrolone and burn management. A total of 18 studies were included in our review. Study Selection and Criteria: The keywords used in our search strategy for PubMed included “oxandrolone” and “burns.” Data Synthesis: The main benefit of oxandrolone is the improved long-term lean body, protein, and bone mineral mass of burn patients. In addition, 3 separate meta-analyses showed oxandrolone shortened length of hospital stay, donor-site healing time, reduced weight loss, and net protein loss. However, oxandrolone therapy did not affect mortality, infection, or liver function. Conclusion: Oxandrolone remains an effective therapy for reducing the hypermetabolic response and comorbidities from burn injuries. Future clinical trials are needed using larger sample sizes and long-term follow-up to determine whether oxandrolone in the context of rehabilitation programs can reduce mortality, lower treatment costs, and improve function outcomes among burn patients.

Hepatic functional pathophysiology and morphological damage following severe burns: a systematic review and meta-analysis

INTRODUCTION

Severe burns are devastating injuries affecting multiple organ systems. Little is known about the influence on the hepatic system and its physiology. This systematic review aimed to assess the current state of research on morphologic liver damage following severe burns.

METHODS

A search was conducted in Pubmed, Web of Science and Cochrane databases using PRISMA guidelines. Outcomes included serum levels of transaminases, fatty infiltration and necrosis. Weighted individual study estimates were used to calculate pooled transaminase levels and necrosis/fatty infiltration rates using a random-effects approach. Risk ratios (RRs) or Odds ratios (ORs) and 95% confidence intervals (CIs) were used to describe pooled estimates for risk factors.

RESULTS

The literature search retrieved 2548 hits, of which 59 studies were included into qualitative synthesis, and finally ten studies were included into meta-analysis. Studies were divided into those reporting autopsies and those reporting changes of serum transaminase levels. The majority of liver autopsies showed fatty infiltration 82% (95% CI39%-97%) or necrosis of the liver 18% (95% CI13%-24%).

DISCUSSION

Heterogeneity in studies on hepatic functional damage following severe burns was high. Only few were well-designed and published in recent years. Many studies could not be included because of insufficient numerical data. There is a high number of patients deceasing from burns that present with fatty infiltration or necrosis of hepatic tissue. Transaminases were elevated during the first days after burn. Further research on how severe burns affect the hepatic function and outcome, especially long-term, is necessary.

A review of the most impactful published pharmacotherapy-pertinent literature of 2019 and 2020 for clinicians caring for patients with thermal or inhalation injury

Keeping abreast with current literature can be challenging, especially for practitioners caring for patients sustaining thermal or inhalation injury. Practitioners caring for patients with thermal injuries publish in a wide variety of journals, which further increases the complexity for those with resource limitations. Pharmacotherapy research continues to be a minority focus in primary literature. This review is a renewal of previous years' work to facilitate extraction and review of the most recent pharmacotherapy-centric studies in patients with thermal and inhalation injury. Sixteen geographically dispersed, board-certified pharmacists participated in the review. A MeSH-based, filtered search returned 1,536 manuscripts over the previous 2-year period. After manual review and exclusions, only 98 (6.4%) manuscripts were determined to have a potential impact on current pharmacotherapy practices and included in the review. A summary of the 10 articles that scored highest are included in the review. Nearly half of the reviewed manuscripts were assessed to lack a significant impact on current practice. Despite an increase in published literature over the previous 2-year review, the focus and quality remain unchanged. There remains a need for investment in well-designed, high impact, pharmacotherapy-pertinent research for patients sustaining thermal or inhalation injuries.

Oxandrolone in Patients on Venovenous Extracorporeal Membrane Oxygenation: A Case Series

Venovenous extracorporeal membrane oxygenation (VV ECMO) induces a systemic inflammatory response, which may progress to persistent inflammation, immunosuppression, and catabolism syndrome (PICS). The anabolic steroid oxandrolone may improve the metabolic aberrations of PICS. We report our experience with 3 patients on VV ECMO who received oxandrolone after demonstrating refractory catabolism on serial nitrogen balance (NB) studies or persistent weakness. Patients in cases 1 and 3 were started on oxandrolone on VV ECMO days 45 and 29, respectively, for negative NB despite nutrition optimization. The case 2 patient started oxandrolone for persistent weakness 68 days after cannulation. All patients demonstrated improvements in NB results. One patient developed mild transaminitis while on oxandrolone, which did not alter his medication course and resolved after the medication was discontinued. The impact of oxandrolone on functional capacity varied between patients. Oxandrolone may be beneficial in persistently catabolic VV ECMO patients to improve NB results. In some patients, this may support functional recovery. Additional research is needed to identify optimal patients for therapy and to investigate the impact of oxandrolone in this population.
