Leorey Saligan

Leorey N. Saligan, Ph.D., R.N., C.R.N.P., is a Assistant Clinical Investigator in the National Institute of Nursing Research (NINR) of the United States National Institutes of Health.

His research interests center around fatigue, particularly fatigue experienced by cancer patients as a result of his parents both being diagnosed with cancer. He has developed an exercise intervention geared to improve aerobic metabolism of patients in order to potentially reduce oxidative stress, inflammation, and fatigue.

Dr Saligan is one of the Associate Investigators assigned to the NIH Post-Infectious ME/CFS Study.

Controversy
In a very small uncontrolled study (n = 9) exploring the relationship between gene expression and pain catastrophizing in fibromyalgia, Saligan and his co-authors used a score of 16 on the Pain Catastrophizing Scale as the threshold for determination of "high catastrophizing". That is in stark contrast with the threshold of 30 recommended by the scale's creators to indicate a "clinically relevant level of catastrophizing," and a mean score for 851 injured workers was 20.90. Even the high catastrophizing subgroup (n = 5) in the study averaged a pain catastrophizing score of only 23.6, well below the recommended threshold. The authors concluded that "specific physiological pathways may possibly delineate pain and catastrophizing mechanisms."

ME/CFS Common Data Element (CDE) Project
Dr Saligan serves on both the Fatigue Working Group and the Pain Working Group of the Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Common Data Element (CDE) Project sponsored by the National Institute of Neurological Disorders and Stroke and the Centers for Disease Control & Prevention.
