Hypochondriasis influences quality-of-life outcomes in patients with chronic fatigue

Abstract:

BACKGROUND: To determine how hypochondriacal symptoms influence the quality-of-life outcomes of patients with a chief complaint of chronic fatigue.

METHODS: Cross-sectional cohort study of a consecutive sample of 71 patients (mean duration of fatigue of 4.1 years). Forty-eight (68%) patients met criteria for current major depression and 32 (45%) met criteria for chronic fatigue syndrome (CFS). All patients received a comprehensive medical and psychiatric evaluation. Quality-of-life and physical, depressive and hypochondriacal symptom scores were assessed through reliable self-report questionnaires and a structured interview. A path model expressing the relation between predictor variables (hypochondriasis and depression), intervening variables (physical symptoms) and quality of life was postulated and evaluated using structural equation methods.

RESULTS: The paths linking hypochondriasis with physical symptoms and mental health and the path connecting physical symptoms and quality of life were each statistically significant. The model applied especially well to patients who fulfilled CFS criteria.

CONCLUSIONS: The quality of life of chronic fatigue patients correlates with the severity of their physical symptoms and their hypochondriacal disposition toward illness.

alpha-Interferon treatment of patients with chronic fatigue syndrome

Abstract:

Thirty patients who fulfilled clinical criteria defined by the CDC for Chronic Fatigue Syndrome were treated with alfa 2a interferon or placebo in a double-blind crossover study. Outcome was evaluated by Natural Killer (NK) cell function, lymphocyte proliferation to mitogens and soluble antigens, CD4/CD8 counts and a 10 item Quality of Life (QOL) survey.

Although mean NK function rose from 87.8 +/- 19.6 to 129.3 +/- 20.7 lytic untis (LU; p < .05) with 12 weeks of interferon therapy, there was no significant change in the other immunologic parameters or QOL scores. When the 26 patients who completed the study were stratified according to their baseline NK function and lymphocyte proliferation, 4 groups were identified: 3 patients had normal NK cell function and lymphocyte proliferation when compared to normal, healthy controls, 9 had isolated deficiency in lymphocyte proliferation, 7 had diminished NK function only, and 7 had abnormalities for both parameters.

QOL scores were not significantly different for the four groups at baseline. After 12 weeks of interferon therapy, QOL score significantly improved in each of the seven patients with isolated NK cell dysfunction (mean score, 16.3 +/- 7.9) compared to baseline (39.7 +/- 12.1; p < .05). In these patients the mean NK function increased from 35.1 +/- 11.7 to 91.5 +/- 22.7 LU (p < .01). Significant improvement was not recorded for QOL in the other three groups. Thus, therapy with alpha interferon has a significant effect on the QOL of that subgroup of patients with CFS manifesting an isolated decrease in NK function.

Quality of life in chronic fatigue syndrome

Abstract:

Whilst the debilitating fatigue experienced in patients suffering from Chronic Fatigue Syndrome (CFS) results in a subjective marked impairment in functioning, little research has investigated the impact of this disorder on quality of life.

Forty-seven subjects with a confirmed diagnosis of CFS and 30 healthy controls were compared using the Sickness Impact Profile (SIP). A subgroup of subjects were interviewed regarding the impact CFS has had on their social and family relationships, work and recreational activities.

Results from both the SIP and the interview revealed that CFS subjects had significantly impaired quality of life, especially in areas of social functioning. These findings highlight the importance of addressing the social isolation and loss of role functioning experienced by CFS sufferers.
