NEW ORLEANS – A proportion of patients treated appropriately with antibiotics for Staphylococcus aureus bacteremia can generate a negative blood culture followed by a positive one, a new clinical entity researchers are calling the “skip phenomenon.”
“This pattern is really in cases where people have known Staph. aureus bacteremia; it seems to clear; they’re on appropriate antibiotic therapy; and despite that, we see that the blood cultures come back positive again several days later,” explained Justin A. Fiala, MD, of Mayo Clinic in Rochester, Minn.
In a video interview, Dr. Fiala outlined the findings of the first study to identify and characterize this phenomenon.
Certain patients with S. aureus bacteremia could be at higher risk for skip phenomenon, for example. The nested case-control study identified these higher-risk patients, a population that might warrant more clinical testing.
Dr. Fiala also discussed associations with patient outcomes, as well as the overall prevalence of skip phenomenon in his research, which included more than 900 patients with S. aureus bacteremia treated at Mayo Clinic.
Dr. Fiala had no relevant financial disclosures.
