This study examines whether the general level and rate of change of
fatigue
over time is different for those rheumatoid arthritis (RA) patients with and those without a history of
affective disorder
(AD). Four hundred fifteen RA patients from a national panel had yearly telephone interviews to obtain
fatigue
and distress reports, and a one-time semistructured assessment of the history of depression and generalized anxiety disorder Growth-curve analysis was used to capture variations in initial
fatigue
levels and changes in
fatigue
over 7 years for those with and without a history. RA patients with a history of major AD reported levels of
fatigue
that were 10% higher than those without a history in the 1st year of the study. Their
fatigue
reports remained elevated over 7 years. Further analysis showed that the effects of a history of AD on
fatigue
are fully mediated through current distress, although those with a history had a significantly smaller distress-
fatigue
slope. Thus, a history of AD leaves RA patients at risk for a 7-year trajectory of
fatigue
that is consistently higher than that of patients without a history. The elevation in
fatigue
reports is, at least in part, a function of enduring levels of distress.

The efficacy of long-term interferon therapy for chronic hepatitis C infection with symptomatic mixed cryoglobulinemia has not clearly been defined. We describe a patient with chronic hepatitis C, symptomatic mixed cryoglobulinemia (cutaneous vasculitis), and membranoproliferative glomerulonephritis (MPGN) who responded clinically, biochemically, and virologically to a 1-year course of interferon therapy. Interferon side effects were minimal. Relapse occurred when interferon was discontinued, and suppressive maintenance interferon therapy was required for clinical, biochemical, and virologic remission. During the 5th year of maintenance therapy, she developed potential side effects that necessitated discontinuation of interferon treatment. After treatment stoppage, a clinical, biochemical, and virologic remission was maintained for more than 1 year. However, the potential side effects, which included eye irritation, arthralgias, myalgias,
fatigue
, insomnia, memory loss, and depression, persisted. Ophthalmologic, rheumatologic, and neurologic evaluations were nondiagnostic. Psychometric testing revealed dementia and
mood disorder
. Because the disabling symptoms persisted after 9 months, a health-related quality of life assessment was carried out with the SF-36 survey. Compared with healthy individuals and patients with chronic hepatitis C, our case had a lower health-related quality of life assessment on six out of seven scales and on four out of seven scales of the SF-36 survey, respectively. This case report indicates that long-term maintenance interferon therapy was effective in the treatment of symptomatic mixed cryoglobulinemia and its renal complications and resulted in a clinical, biochemical, and virologic sustained response. It is postulated that the side effects of long-term interferon therapy in this setting may be problematic.

Chronic fatigue syndrome (CFS) is characterized by unexplained, disabling
fatigue
and is associated with high rates of comorbid depression. While the aetiology is unknown, findings from recent twin surveys suggest that genetic factors may be relevant to prolonged
fatigue
states (> 1 month). To date, however, there has been no exploration of the role of familial/genetic factors in operationally defined CFS. The aims of the present study were: (i) to examine whether CFS is familial by comparing the rates of CFS in the first-degree relatives of CFS cases and medical control subjects; and (ii) to determine whether the high rate of comorbid depression in CFS is reflected in a greater familial loading for
affective disorder
. Twenty-five CFS cases and 36 medical control subjects were assessed for
fatigue
symptoms based on the Centre for Disease Control (CDC) criteria for CFS, and for lifetime psychiatric symptoms using the Schedule for Schizophrenia and
Affective Disorders
-Lifetime Version. Informant family history was obtained regarding first-degree relatives using the CDC criteria and the Family History Research Diagnostic Criteria. In addition, informant history was supplemented by sending a questionnaire to first-degree relatives. There were significantly higher rates of CFS in the relatives of CFS cases compared with the relatives of control subjects. The rate of depression in the CFS cases was similar to previous studies but did not appear to reflect a greater familial loading for depression when compared with control subjects. However, these analyses were complicated by higher than expected rates of depression in the control group. These findings suggest that familial factors are important in the aetiology of chronic fatigue syndrome.

Psychiatric morbidity among foreign tourists is usually connected to external factors such as unfamiliar surroundings, language problems, and special religious experiences, as well as biological factors such as dyschronism of circadian rhythms. Long-range flights through several time zones are typically followed by symptoms of jet lag such as
fatigue
, severe sleep schedule disturbance, impairment of cognitive functions, and even mild depression. Jet lag is generally attributed to a conflict between external time cues and internal biological rhythms. This study examined the possible association between jet lag and psychiatric morbidity among long-distance travelers hospitalized in the Jerusalem Mental Health Center, Kfar Shaul Hospital between 1993 and 1998. This was a prospective open-label study. Patients (n = 152) were divided into two groups based on the number of time zones crossed in the flight to Israel: group I, seven time zones or more (n = 81); and group II, three time zones or less (n = 71). The direction of flight was mainly eastbound. After controlling the two groups for demographic and religious background, past psychiatric history, and diagnosis on admission (P > 0.1, Fisher's exact test), the possible association between jet lag and psychotic or major
affective disorder
was evaluated according to the following criteria: (1) absence of major mental problems before the flight or good remission of an existing disorder 1 year or more before flight; and (2) the appearance of psychotic or major affective syndromes during the first 7 days after landing. The number of first psychotic/major affective episodes in both groups presumed as associated with jet lag was found similar (P =.5), whereas the number of relapses conjoint with jet lag in the seven or more time zone group was significantly higher (P =.04). The results suggest that the dyschronism of circadian rhythms and jet lag possibly play a role in the exacerbation of major psychiatric disorders.

Klinefelter's syndrome (KS) concerns men and is usually characterized by tallness, underdeveloped testes and sterility. It is generally due to the 47,XXY genotype, ie one extra X chromosome in each cell. Its estimated frequency among newborn boys is 1/500 to 1/700. It seems that 64% KS would be undiagnosed. Abnormally low levels of testosterone blood values are very common in this syndrome. In this case, replacement androgen therapy should be initiated (ideally at the age of 11-15) which prevents osteoporosis and enhances secondary sexual features. Case report - Since early childhood, Mr X has been shy, passive with few friends. When he was 13 years old, the school physician noted a delay of puberty and referred him to an endocrinologist who diagnosed KS. Androgen therapy was introduced but rapidly stopped, because the boy and his parents thought it was useless. Mr X consulted a psychiatrist at the age of 21. He presented a schizo-
affective disorder
with influence syndrome, auditory and visual hallucinations, labile mood with disinhibited and depressive periods. He was admitted in a psychiatry ward of a general hospital. An endocrinologist confirmed the diagnosis of KS and found very low blood testosterone levels. Besides lithium and risperidone which had already been introduced before the hospitalization, androgens (testosterone undecanoate) were very progressively given to Mr X with a daily psychiatric evaluation. One month after discharge, a major depressive episode led to the adjunction of citalopram. After one year of follow-up, Mr X shows increased social adjustment and enhanced interest; the influence syndrome has partially regressed and his mood is more stable. Discussion - In the years '60 and '70, systematic screenings in psychiatric hospitals have detected 1.3% KS among hospitalized boys, ie 10 times more than in the general population, and 0.6 to 1% KS among hospitalized men. A large variety of psychiatric disorders have been described. Boys presenting KS are usually described as shy, with little energy and initiative, and few friends. They cry more often than compares. Neuropsychological studies demonstrate significantly lower verbal IQ than controls, while performance IQ is generally normal and global IQ is in the normal range with large individual variations. Language acquisition is always delayed. However, agressiveness is not increased. In his follow-up study of 20 years, Nielsen at al found more psychiatric disorders among KS patients, compared to a group of hypogonadal patients at first examination (mean age=27 years). After 20 years follow-up, however, no significant difference remained between the two cohorts concerning the frequency of psychiatric hospitalizations or mental diseases. Several hypotheses have been proposed to explain psychological aspects of KS such as low levels of androgens during foetal and child development, personality disorder related to hypogonadism, delay of mitosis of cells with an extra X chromosome, but none of them is able to explain the specificity of psychological problems associated with KS. Concerning therapeutic aspects, specialists prone substitutive androgen therapy in case of too low testosterone blood levels, from the time of increase in FSH (around the age of 11-15). It prevents osteoporosis, backache and excessive
tiredness
often found in males with KS; testosterone also improves social drive, mood, concentration and ability at work. If KS diagnosis is made at adult age, androgen therapy has also shown some efficacy, though less than if started earlier. Due to the oral and written language problems of KS boys between 5 and 12 years of age, Graham et al. recommend anticipatory guidance for these boys. In addition, they insist on the importance of the information of the parents, language therapy, the reduction of the length of the instructions given by schoolmasters and specially stimulating and stable childhood conditions. Though it is generally thought that androgens increase agressiveness, we found no consistent data in litterature proving that the restoration of physiological androgen blood levels increases crimes nor aggressiveness. In the contrary, Miller and Sulkes described four cases of KS men presenting chronic fire-setting behaviors. Testosterone was introduced. For three of them, follow-up was available: their behavior seemed improved and none of them recurred. However, the initiation of androgen therapy for patients with severe psychiatric illness should be done very carefully. Conclusion - The Klinefelter's syndrome is frequent and, if not diagnosed (which seems to be the most common case), these men have higher risks to develop psychiatric disorders. Therefore, child psychiatrists and psychiatrists should evoke that diagnosis when they examine boys or men who present typical physical traits of KS (tallness, underdevelopped testes) associated to school problems and/or psychiatric disorders. Indeed, if the diagnosis is confirmed by an endocrinologist and a genetic testing, psychological follow-up and testosterone undecanoate treatment (in case of abnormal testosterone blood levels) should be initiated. This therapy generally improves physical well-being and improves mood, concentration, capacity at work. There is no consistent data in the litterature proving that restoring physiological testosterone blood levels would be dangerous for KS men presenting severe psychiatric troubles. However, this should be discussed in each situation with caution, and androgens should be introduced very progressively.

The sleep apnea syndrome (SAS), which is defined by more than 5 apneas or hypopneas per hour of sleep (9), is quite a frequent affection which concerns 1.4 to 10% of general population (1.7). The major daytime complaints of the SAS are daytime sleepiness, memory and attention disorders, headaches and asthenia especially in the morning, and sexual impotence (9). The nocturnal manifestations are dominated by sonorous and generally long standing snoring, increased by dorsal decubitus and intake of alcohol, with repeated interruptions by respiratory arrests. These manifestations are always noted but rarely spontaneously reported. The sleep, non refreshing, is agitated and perturbed by numerous awakenings. The findings of the clinical examination are poor: obesity is found in 2/3 of the cases and arterial hypertension in 1/2 of the cases (20). Polygraphic recording during sleep only permits an absolute diagnosis. This frequent affection is a real problem of public health because of its numerous complications (3, 10, 12, 13, 18, 21). Symptoms of depression are often found when a patient with a SAS is examined and conversely, symptoms which evoke a SAS can be found in the clinical examination of depressed patients. We decided so to study the thymic and anxious status of 24 patients investigated for a SAS and submitted to a polygraphic recording during sleep. Four clinical parameters were studied: DSM III-R diagnosis criteria, Montgomery and Asberg Depression Rating Scale (MADRS), Hamilton Anxiety Rating Scale (HARS) and thymasthenia rating scale of Lecrubier, Payan and Puech. We also reported Total Sleep Time (TST = 6.5 +/- 1.5), Apnea Hypopnea Index (AHI = 26.7 +/- 21.6), number (2.1 +/- 2.8/h) and duration (174.2 +/- 150.8 s/h) of hypoxic events. Results showed that among 24 patients, 8 were depressed according to DSM III-R diagnosis criteria and had MADRS > 25, 22 were anxious, 11 had a major anxiety (HARS > 15) and 15 presented thymasthenia (SET > 15). Significative correlations existed between anxiety and depression (r = 0.82; p < 0.0001), depression and thymasthenia (r = 0.77; p < 0.0001) and thymasthenia and anxiety (r = 0.75; p < 0.0001). Among the 8 depressed patients a correlation existed between AHI and depression (r = 0.72; p = 0.04), but no correlation was found between depression and hypoxic events. These results were comparable to those of Guilleminault (10), Reynolds (21), Kales (12), Bliwise (3), Klonoff (13) and Millman (18) who studied relations between SAS and depression. The evaluation of thymasthenia gave a more precise typology of the depressive state associated to SAS: the type of the
mood disorder
is more "blunted" and "anhedonic" than "sorrowful", particularly characterised by asthenia,
lack of energy
, reduction of interests (leisures, libido, work), loss of initiative, difficulties to organise tasks, fall of performances and reduction of pleasure usually felt in pleasant events (15). The physic symptomatology dominated the psychic one. The sleep disorganization, more than metabolic consequences of apneas, could be involved in this associated depressive state. Other neuropsychiatric troubles can be associated to the SAS. In fact, cognitive troubles (2, 8, 14, 16, 19, 22, 24) and personality disorders (12, 18) have been described. Our data confirm previous observations suggesting a frequent association between SAS, depression,
fatigue
and anxiety. Clinicians should consequently be aware that a depression with severe complaints of
fatigue
should deserve an investigation oriented towards SAS. Conversely, when a SAS is diagnosed, it is necessary to look for a possible depression in order to set up the most appropriate treatment. The frequency of SAS, like depression's one, increases with age. Prescription and consummation of sedative psychotropic drugs increase too with age. Since respiratory depressant effects of these drugs have been clearly demonstrated, it is important to evoke SAS when depressive and/or anxious states are diagnosed and not to aggravate it. An efficacious treatment of SAS can also cure the associated depressive state, but this one can persist. It is necessary, in this case, to select a non sedative antidepressant.

The objective was to compare the prevalence and severity of
fatigue
in patients with Parkinson's disease (PD) with that in two control groups, one consisting of randomly chosen control subjects of the same age and sex distribution and the other consisting of patients with coxarthrosis waiting to receive total hip replacement. We also explored the possible correlation of demographic and clinical data to the presence and severity of
fatigue
. Sixty-six patients with PD, 131 randomly chosen controls and 79 patients with coxarthrosis, waiting to receive total hip replacement, were evaluated for
fatigue
. Patients and controls with a depressive
mood disorder
or cognitive impairment had been excluded from the study.
Fatigue
was measured by the
Fatigue
Severity Scale (FSS). For the patients with PD the mean total FSS score was 4.1, compared with 2.7 amongst the randomly chosen control group and 2.9 in the group consisting of patients with coxarthrosis. Fifty per cent of the patients with PD had a mean total FSS score of 4 or higher, compared with 25% in both of the two control groups. There was no correlation between pain, presence of self-reported nocturnal sleep disorders or duration of PD and
fatigue
. The patients with
fatigue
did have a more advanced disease, measured both by Unified Parkinson's Disease Rating Scale score and Hoehn and Yahr stage. Although the univariate analyses indicated that more severe parkinsonism was correlated to the symptom, the multivariate analysis showed that none of the studied variables were significant explanatory factors for
fatigue
.
Fatigue
is a common symptom in patients with PD without depression or dementia. The study indicates that
fatigue
is an independent symptom of the disease without relation to other motor or non-motor symptoms.

The aim of the present study was to investigate the effects of a group structured intervention on the mental and physical discomfort and immune function of 20 family caregivers. A structured intervention for caregivers consists of five sessions, each of which lasts 90 min. This was a modified version of the program that had been originally developed for cancer patients. All the family caregivers were female and ranged in age from 47 to 66 years (mean: 54.7 +/- 4.4). The period of care at home ranged from 1 to 12 years (mean: 5.8 +/- 2.7). Concerning the original diseases of the care-receivers, 10 had vascular dementia and eight had Alzheimer's disease. Nine out of 20 caregivers had no care support, and seven utilized no public resources such as day-care centers. Only five caregivers felt that they were healthy. Two psychometries, that is, Profile of Mood States (POMS) and General Health Questionnaire-30 (GHQ-30) were administered and blood samples were drawn before and after intervention. Comparison of results showed that there was significant improvement (P < 0.05) in the scores of depression, anger-hostility,
fatigue
and confusion in the POMS, and physical symptoms, anxiety-
mood disorder
, suicidality-depression in the GHQ-30. Also, there was significant (P = 0.0325) augmentation of natural-killer cell activity. The present study suggests that this kind of intervention was effective for relieving emotional and physical discomfort, and also for improving immune function.

Psychological depression is shown to be associated with several aspects of coronary artery disease (CAD), including arrhythmias, myocardial infarction, heart failure and sudden death. The physiological mechanisms accounting for this association are unclear. Hypothalamic-pituitary-adrenal dysregulation, diminished heart rate variability, altered blood platelet function and noncompliance with medial treatments have been proposed as mechanisms underlying depression and cardiovascular disease. Recent evidence also suggests that reduced baroreflex sensitivity, impaired immune function, chronic
fatigue
and the co-morbidity of depression and anxiety may be involved in the relationship between depression and cardiovascular dysregulation. An experimental strategy using animal models for investigating underlying physiological abnormalities in depression is presented. A key to understanding the bidirectional association between depression and heart disease is to determine whether there are common changes in brain systems that are associated with these conditions. Such approaches may hold promise for advancing our understanding of the interaction between this
mood disorder
and CAD.

Multiple sclerosis (MS) is one of the most studied neurological diseases, although scarce attention has been placed on symptomatic therapy. The aim of the study was to evaluate the frequency of medication prescription for the major symptoms related to MS in order to better understand the needs of patients. The study was conducted during an epidemiological survey in the province of Genoa, Italy. Out of 856 patients with MS in the study area, 665 agreed to participate in a structured interview. Two hundred and forty-nine (37%) subjects, with a mean age of 53 years and a mean Expanded Disability Status Scale (EDSS) score of 5.2, were taking at least one symptomatic medication. Four hundred and sixteen (63%) subjects, with a mean age of 49 years and a mean EDSS score of 4.5, were not using symptomatic therapy. The most commonly treated symptoms were pain (28%), spasticity (27%) and
mood disorder
(16%), while bladder dysfunction (8%) and
fatigue
(3%) were less frequently treated with medication. Seventy-seven patients (12%) were taking medications for reasons not directly related to MS. This cross-sectional study underlines the frequency of medication prescription for symptoms such as spasticity and pain, while other common symptoms, such as bladder dysfunction and
fatigue
, may perhaps be undertreated. The present findings also underline the need for clinical trials on symptomatic therapies.
