Abstract
Hyperventilation has been suggested as a concomitant and possible
maintaining factor that may contribute to the symptom pattern of
chronic fatigue syndrome (CFS). Because patients accepting the illness
and trying to live with it seem to have a better prognosis than
patients chronically fighting it, we investigated breathing behavior
during different coping response sets towards the illness in patients
with CFS (N=30, CDC criteria). Patients imagined a relaxation script
(baseline), a script describing a coping response of hostile
resistance, and a script depicting acceptance of the illness and its
(future) consequences. During each imagery trial, end-tidal PCO_2
(Handheld Capnograph, Oridion) was measured. After each trial,
patients filled out a symptom checklist. Results showed low resting
values of PetCO_2 overall, while only imagery of hostile resistance
triggered a decrease and deficient recovery of PetCO_2. Also, more
hyperventilation complaints and complaints of other origin were
reported during hostile resistance imagery compared with acceptance
and relaxation. In conclusion, hostile resistance seems to trigger
both physiological and symptom perception processes contributing to
the clinical picture of CFS.
...
In summary, CFS patients adopting an action set of hostile resistance
towards their illness report more negative affect, more subjective
complaints, and tend to hyperventilate, which may last and aggravate
beyond the duration of actively adopting this action set. Conversely,
adopting an action set of acceptance is associated with less negative
affect, less subjective complaints, and no hyperventilation. Our
results suggest that the promotion of acceptance as a coping strategy
may have good additive value to the existing revalidation program,
which currently consists of traditional cognitive behavioral therapy
and graded exercises.
