Abstract
BACKGROUND:
Previously, we reported a randomized placebo-controlled trial, the Qure study, showing that cognitive behavioural therapy (CBT), and not doxycycline, was significantly more effective than placebo in reducing fatigue severity in Q fever fatigue syndrome (QFS) patients. This follow-up study evaluates the long-term effect of these treatment regimens, 1 year after completion of the original trial.
METHODS:
All patients who completed the Qure study, CBT (n = 50), doxycycline (n = 52), and placebo (n = 52), were included in this follow-up study. Between twelve and fifteen months after end of treatment (EOT), patients filled out web-based questionnaires including the main outcome measure fatigue severity, assessed with the Checklist Individual Strength (CIS), subscale fatigue severity.
RESULTS:
Fatigue severity in the CBT, but not doxycycline or placebo, group was significantly increased at follow-up compared to EOT (respective means 39.5 [95% CI, 36.2-42.9] and 31.3 [95% CI, 27.5-35.1], mean difference 8.2 [95% CI, 4.9-11.6]; P < .001). Fatigue severity scores of CBT (adjusted mean 39.8 [95% CI, 36.1-43.4]) and doxycycline (adjusted mean 41.0 [95% CI, 37.5-44.6]) groups did not significantly differ from the placebo group (adjusted mean 37.1 [95% CI, 33.6-40.7]; P = .92 and P = .38, respectively).
CONCLUSION:
The beneficial effect of CBT on fatigue severity at EOT was not maintained 1 year thereafter. Due to its initial beneficial effect and side effects of long-term doxycycline use, we still recommend CBT as treatment for QFS. We suggest further investigation on tailoring CBT more to QFS, possibly followed by booster sessions

Note: I decided to post in this category because Q-Fever is one of the ME/cfs trigger.
Edit to add: Apologies, this is not a new paper, it dates from Nov 2018
