The relationship between fatigue, psychological and immunological variables in acute infectious illness.

OBJECTIVE: The aim of this paper is to explore the longitudinal relationships between physical and psychological symptoms and immunological factors following acute infective illnesses. METHOD: Preliminary data from a prospective investigation of patients with serologically proven acute infectious illnesses due to Epstein-Barr virus (EBV), Ross River virus (RRV) or Q fever are reported. Patients were assessed within 4 weeks of onset of symptoms and then reviewed 2 and 4 weeks later. Physical illness data were collected at interview. Psychological and somatic symptom profiles were assessed by standardised self-report questionnaires. Cell-mediated immune (CMI) function was assessed by measurement of delayed-type hypersensitivity (DTH) skin responses. RESULTS: Thirty patients who had been assessed and followed over the 4-week period (including 17 patients with EBV, five with RRV and eight with Q fever) were included in this analysis. During the acute phase, profound fatigue and malaise were the most common symptoms. Classical depressive and anxiety symptoms were not prominent. Initially, 46% of cases had no DTH skin response (i.e. cutaneous anergy) indicative of impaired cellular immunity. Over the 4-week period, there was a marked improvement in both somatic and psychological symptoms, although fatigue remained a prominent feature in 63% of subjects. The reduction in reported fatigue was correlated with improvement in the DTH skin response (p = 0.001) and with improvement in General Health Questionnaire (GHQ) scores (p < 0.01). CONCLUSIONS: Acute infectious illnesses are accompanied by a range of nonspecific somatic and psychological symptoms, particularly fatigue and malaise rather than anxiety and depression. Although improvement in several symptoms occurs rapidly, fatigue commonly remains a prominent complaint at 4 weeks. Resolution of fatigue is associated with improvement in cell-mediated immunity.

Fatigue in selected primary care settings: sociodemographic and psychiatric correlates.

OBJECTIVES: To determine the prevalence and sociodemographic and psychiatric correlates of prolonged fatigue syndromes among patients in primary care. DESIGN: Prospective questionnaire survey. PATIENTS AND SETTING: Adults over 18 years attending three general practices in metropolitan Sydney and one on the Central Coast, north of Sydney. RESULTS: Of 1593 patients, 25% had prolonged fatigue, while 37% had psychological disorder. Of the patients with fatigue, 70% had both fatigue and psychological disorder, while 30% had fatigue only. The factors associated with prolonged fatigue were concurrent psychological disorder, female gender, lower socioeconomic status and fewer total years of education. Patients with fatigue were more likely to have a current depressive disorder. CONCLUSIONS: Prolonged fatigue/neurasthenia syndromes are common in Australian primary care settings, and are commonly associated with current depressive disorders. Such syndromes, however, do not fit readily into current international psychiatric classification systems.

Duane syndrome and congenital upper-limb anomalies. A familial occurrence.

We report a family in which five members in three generations have been afflicted with Duane syndrome. Four of the five members also have congenital hypoplasia of the thenar eminence. One also was afflicted with Hirschsprung disease and another was born deaf. A sixth member, who does not have Duane syndrome, is afflicted with a more extensive malformation of the upper extremities and unilateral deafness. We present a discussion of Duane syndrome and its association with other congenital anomalies. Although some members of this family presented in this report show features that are similar to the Holt-Oram syndrome, Wildervanck's syndrome, and others reported in the literature, there are several unique features about this family that we thought were worth reporting.
