Factors associated with psychiatric outcomes and coping in Long COVID

Abstract:

The relationship between Long COVID (LC) and psychiatric outcomes, as well as factors associated with presence and absence of these, has so far been insufficiently studied. Here we evaluated psychiatric symptoms and coping among patients with LC and patients recovered from COVID-19 who participated in a large international survey. Given increased rates of psychiatric illness with chronic medical conditions and known immune-inflammatory contributors to psychiatric disease, we hypothesized that a subset, but not the entirety, of LC respondents may have comorbid psychopathology.

A substantial minority of both groups experienced suicidality, depression and anxiety symptoms, with these symptoms being more common in the LC group. LC respondents used more adaptive coping styles. Psychiatric outcomes in LC were associated with younger age, greater reductions in overall health, higher symptom severity, limitations to physical capability, lower income, financial hardship, psychiatric history, employment impact, male sex, men and non-binary gender, and negative experiences with medical professionals, family, friends, partners and employers.

Screening for prolonged fatigue syndromes: validation of the SOFA scale

Abstract:

BACKGROUND: The identification of syndromes characterised by persistent and disabling mental and/or physical fatigue is of renewed interest in psychiatric epidemiology. This report details the development of two specific instruments: the SOFA/CFS for identification of patients with chronic fatigue syndrome (CFS) in specialist clinics and the SOFA/GP for identification of prolonged fatigue syndromes (PFS) in community and primary care settings.

METHODS: Patients with clinical diagnoses of CFS (n = 770) and consecutive attenders at primary care (n = 1593) completed various self-report questionnaires to assess severity of current fatigue-related symptoms and other common somatic and psychological symptoms. Quality receiver operating characteristic curves were used to derive appropriate cut-off scores for each of the instruments. Comparisons with other self-report measures of anxiety, depression and somatic distress are noted. Various multivariate statistical modelling techniques [latent class analysis (LCA), longitudinal LCA] were utilised to define the key features of PFS and describe its longitudinal characteristics.

RESULTS: The SOFA/CFS instrument performs well in specialist samples likely to contain a high proportion of patients with CFS disorders. Cut-off scores of either 1/2 or 2/3 can be used, depending on whether the investigators wish to preferentially emphasise false-negatives or false-positives. Patients from these settings can be thought of as consisting not only of those with a large number of unexplained medical symptoms, but also those with rather specific musculoskeletal and pain syndromes. The SOFA/GP instrument has potential cut-off scores of 1/2 or 2/3, with the latter preferred as it actively excludes all non-PFS cases (sensitivity = 81%, specificity = 100%). Patients with these syndromes in the community represent broader sets of underlying classes, with the emergence of not only musculoskeletal and multisymptomatic disorders, but also persons characterised by significant cognitive subjective impairment. Twelve-month longitudinal analyses of the primary care sample indicated that the underlying class structure was preserved over time. Comparisons with other measures of psychopathology indicated the relative independence of these constructs from conventional notions of anxiety and depression.

CONCLUSIONS: The SOFA/GP instrument (which is considerably modified from the SOFA/CFS in terms of anchor points for severity and chronicity) is preferred for screening in primary care and community settings. Patients with PFS and CFS present a range of psychopathology that differs in its underlying structure, cross-sectionally and longitudinally, from coventional notions of anxiety and depression.

Behavioural effects of infectious mononucleosis

Abstract:

The aim of the present study was to provide preliminary information on the acute and chronic effects of infectious mononucleosis (IM) on memory, attention, psychomotor performance and mood. These issues were examined by comparing individuals with acute IM, those who had the initial illness some months before, and matched healthy controls.

Objective measures of memory, attention, motor skills and visual functions were obtained, as were subjective reports of mood. The results showed selective effects of acute IM on performance and mood, with the profile of impairments being very similar to those observed in previous studies of influenza.

Different impairments were observed in subjects who had the primary illness several months before, and the effects observed in this group were similar to those observed in recent studies of chronic fatigue syndrome patients.

Both acute and chronic IM subjects reported similar levels of symptoms and psychopathology, with both groups having greater scores than the controls. However, the performance impairments did not reflect symptoms or psychopathology. One may conclude that the study of IM will provide important data on both the acute and longer lasting effects of viral infections on the brain and behaviour.

Behavioural problems associated with the chronic fatigue syndrome

Abstract:

Disturbances of memory, concentration and motor function are often reported by patients with the chronic fatigue syndrome (CFS). The present study objectively evaluated these behavioural problems using a computerized test battery measuring memory, attention and motor skills.

Fifty-seven CFS patients were compared with 19 matched controls and all subjects completed the performance test battery and filled in questionnaires measuring psychopathology and mood. The patients reported significantly higher levels of depression, anxiety, physical symptoms and cognitive failures than the controls. Similarly, they reported more negative affect at the time of testing.

The patients were slower on psychomotor tasks, showed increased visual sensitivity and impaired attention. Digit span and free recall were not impaired but retrieval from semantic memory and logical reasoning were slower. None of the performance differences between patients and controls could be attributed to differences in psychopathology. These results agree with recent findings from other laboratories, and it is now time to consider the nature of the neurological dysfunction underlying these effects.

A practical approach to chronic fatigue syndrome

Abstract:

Chronic fatigue may have several physical causes, but a psychiatric condition is often involved. A substantial minority of patients are not diagnosed by conventional tests and do not respond to antidepressant therapy. These patients should be referred for psychiatric opinion or observed for new developments. Extensive virologic testing and unorthodox treatment approaches have no scientific basis at present. Claims of dramatic new diagnostic tests or therapy should be treated with caution because of the long history of unsuccessful attempts to categorize chronic fatigue into one diagnosis and the strong placebo effect shown in controlled trials.

Myalgic encephalomyelitis

Comment on: Myalgic encephalomyelitis: an alternative theory. [J R Soc Med. 1990]

 

I am pleased that Dr Wilson (August 1990 JRSM, p481) has paid me the compliment of giving my article on the vexed topic of ‘myalgic encephalomyelitis’ (April 1989 JRSM, p 215) serious attention, and echoes our call’ for a ‘new approach’ to the problem, based on an absence of prejudice and a sound clinical and social history. He also notes the parallels between neurasthenia and ‘ME’, although the former was not, as he writes, first described in 18842. However, I only wish I could follow the rest of his arguments so clearly:

Dr Wilson states that I failed to realize that ‘about 100%’ of patients have an allergic diathesis and an allergic family history. I was indeed unaware of this remarkable finding. Unfortunately, I have been unable to trace the two sources cited for this observation, one an American paperback, the other a society newsletter. Similarly, I am afraid that neither I nor any of my colleagues have ever met anyone suffering from ‘Alternate Multiple Personality’. Perhaps this was because I was again unaware of the relevant literature. However, in my defence I would not otherwise have known that the two references quoted, namely Dr Wilson’s paper on allergic disease, multiple personality and dowsing, and his paper on possession and multiple personality, are actually about chronic fatigue syndrome. Similarly, I would not have known that an article in the Christian Parapsychologist called ‘Deliverance and dowsing’ is on the psychopathology of allergy and ME, nor that information on treatment of ME would be published in a series of titles beginning with ‘Current theological perspectives on possession. It is becoming harder to keep up with the relevant literature.
