Son: Analysis of Patients Visiting an Oriental Hospital with Idiopathic Chronic Fatigue or Chronic Fatigue Syndrome

Abstract

Objectives:

Medically unexplained fatigue includes chronic fatigue syndrome (CFS) and idiopathic chronic fatigue (ICF). These disorders quite impair quality of life while no effective therapies exist. Therefore, patients with CFS or ICF frequently choose treatments based on traditional Korean medicine. The study aimed to analyze characteristic of patients visiting an Oriental clinic with CFS or ICF.

Methods:

Patients who met criteria for CFS or ICF were enrolled in this study, from March 2011 to Jun 2013. Clinical information focused on symptom differentiation and Sasang constitution was analyzed. Pearson’s chi-square test was used to compare the frequency among sub-groups.

Results:

In total, 77 patients (49 male and 28 female) were diagnosed with CFS (17 male and 13 female) or ICF (32 male and 15 female). The symptom differentiation was 37.7%, 26.0%, 13.0%, and 23.3% for “Qi deficiency of both spleen and lung ( jkm-34-3-119-10i1.tif)”, “Yin deficiency of both liver and kidney ( jkm-34-3-119-10i2.tif)”, “Blood deficiency of both heart and spleen ( jkm-34-3-119-10i3.tif)” and “Yang deficiency of both spleen and kidney ( jkm-34-3-119-10i4.tif)”, while Sasang constitutional distribution was 59.7%, 22.1% and 18.2% Soeumin, Taeumin and Soyangin, respectively. The fatigue severity was notably different between CFS (63.7 ± 12.1) or ICF (52.2 ± 15.3) according to the Chalder fatigue scale (10-point scale for eleven questions). There was statistical significance regarding symptom differentiation and Sasang constitution (p < 0.05).

Conclusions:

In the process of traditional Korean medicine-based development of therapeutics for patients with chronic fatigue or related conditions, this report can serve as reference data.
