Assessing Fatigue in Scleroderma

In April 2008 Brett Thombs and co-investigators Murray Baron, Marie Hudson, Eva Libman and Suzanne Taillefer were awarded a grant from the Fonds de la recherche en santé du Québec (FRSQ) to develop a systematic approach to assessing fatigue in Scleroderma. Persistent fatigue plays a crucial role in determining Health-Related Quality of Life (HRQoL) in chronic disease and unfortunately it is often overlooked by clinicians and researchers. Two important factors that make addressing fatigue difficult are (1) the lack of an agreed-upon standard for identifying clinically significant fatigue, and (2) an insufficient understanding of fatigue etiology that hinders treatment development. With this grant, researchers plan to address these issues by building on research done on Chronic Illness-Related Fatigue in cancer patients.

There are five overall objectives: (1) to validate a Chronic Illness-Related Fatigue case-definition for SSc and to assess its measurement equivalence in samples of SSc and cancer patients in order to establish the degree to which it represents a viable unifying framework for fatigue assessment; (2) to compare three widely-used fatigue measurement scales in order to determine the scale with the best validity and reliability characteristics in SSc; (3) to develop a brief screening tool that is sensitive and specific for Chronic Illness-Related Fatigue; (4) to identify demographic, disease and psychosocial factors related to Chronic Illness-Related Fatigue in SSc; and (5) to determine the relationship between fatigue and circulating biomarkers in SSc.

To meet these objectives researchers will use information from patients enrolled in the CSRG Registry. Patients will fill-out three widely-used fatigue measurement scales at their annual visit and a certain subset of these individuals will undergo a diagnostic interview for Chronic Illness-Related Fatigue. Specimens of blood drawn at each visit will also be tested for cytokine biomarkers.

It is well known that chronic illnesses, such as SSc, are becoming an increasingly larger concern of health care system around the world and given that fatigue is known to decrease HRQoL and increase disability in such illnesses, it is imperative that a fatigue assessment tool be developed and validated for individuals with SSc.
