Severe Fatigue in Inflammatory Bowel Disease: Dopaminergic Therapy With Modafinil or Vitamin Therapy With Thiamine.

We found Moulton et al's1 illustrative case series of 10 patients with inflammatory bowel disease (IBD) and chronic fatigue, all presenting with depression, particularly interesting. 1 Among the patients, 8 previously had undergone treatment with multiple psychotropic medications, and 2 had active IBD as indicated by increased fecal calprotectin levels. Remarkably, all 10 patients responded positively to open-label treatment with modafinil, a central nervous system stimulant that blocks dopamine reuptake transport, which resulted in an impressive improvement in their fatigue symptoms. At baseline, the self-reported mean fatigue score was 16, measured on the IBD Fatigue Assessment Scale (IBD-FAS), which ranges up to 20, and with levels higher than 11 indicating severe fatigue. After 6 months of modafinil treatment, the mean fatigue score was 6.7.1.
