Bottom line: Though patients who take steroids are predisposed to infections of all kinds, no large studies have implicated steroid usage as an independent risk factor for pyogenic liver abscesses. Review articles and evidence summaries do not list steroid usage when discussing the etiology of hepatic abscesses.

In stating, “Hepatic abscesses commonly arise as a result of immunosuppression, notably….steroid therapy,” this case report of a 78-year-old female on long-term steroid treatment who developed a pyogenic liver abscess cites Kandel and Wintch (see next entries).

In stating that “patients with certain underlying conditions associated with immunosuppression, notably…steroid therapy…, are predisposed to infections of all kinds, including intrahepatic abscesses,” this review article cites Wintch (see next entry).

In a comparison of the clinical course of 25 patients with liver abscesses with a previous series of 22 patients with the same condition, six of the 25 patients with hepatic abscesses had immunologic and hematologic deficiencies. A paragraph that includes “ailments associated with steroid therapy” in a list of “frequently noted diseases,” cites three articles, one of which is a study by Sabbaj of 25 patients with anaerobic pyogenic liver abscesses that listed corticosteroid therapy as a potential cause in one of 11 patients for which the authors found potential sources of the infection.
