Hormonal trends in patients suffering from long COVID symptoms

Abstract:

Symptoms of long COVID are complex and long-lasting, and endocrine dysfunction might be involved in the underlying mechanisms. In this study, to clarify the hormonal characteristics of long COVID patients, laboratory data for patients who visited the outpatient clinic for long COVID were evaluated. A retrospective analysis was performed for patients who visited Okayama University Hospital during the period from Feb 2021 to Dec 2021 with focus on the interrelationships between major symptoms and endocrine data.

Information and laboratory data were obtained from medical records for 186 patients. The patients had various symptoms, and the most frequent symptoms were general malaise, dysosmia/dysgeusia, hair loss, headache, dyspnea, and sleeplessness. Patients who were suffering from fatigue and dysosmia/dysgeusia were younger, while hair loss was more frequent in older and female patients.

As for the characteristics of patients suffering from general fatigue, the scores of depression and fatigue were positively correlated with serum levels of cortisol and free thyroxin (FT4), respectively. Also, patients suffering from general fatigue had lower levels of serum growth hormone and higher levels of serum FT4, while patients with dysosmia/dysgeusia had a significantly lower level of serum cortisol. Serum thyrotropin (TSH) levels were higher and the ratios of FT4/TSH were lower in the initially severe cases, suggesting occult hypothyroidism. In addition, the ratios of plasma adrenocorticotropin to serum cortisol were decreased in patients with relatively high titers of serum SARS-CoV-2 antibody. Thus, hormonal changes seem to be, at least in part, involved in the persistent symptoms of long COVID.

Chronic fatigue syndrome versus neuroendocrineimmune dysfunction syndrome:differential attributions

Abstract:

Since 1988, when the term chronic fatigue syndrome (CFS) was coined, considerable discussion has occurred about stigma associated with this diagnostic term. In particular, patients with CFS have felt that this term trivializes the serious nature of this disorder. A Name Change Work group, appointed by the CFS Coordinating Committee, developed an umbrella term: chronic neuroendocrineimmune dysfunction syndrome (CNDS), and proposed that there would be sub-types under this term, one being CFS. The present study examined attributions of this new umbrella term when compared with CFS.

Nurses and physician assistants (PAs) were presented a case study of a patient with symptoms of CFS. They were told that the patient had either “chronic fatigue syndrome,” “chronic neuroendocrineimmune dysfunction syndrome,” or “chronic neuroendocrineimmune dysfunction syndrome, which had formerly been called chronic fatigue syndrome.” The different terms led to different attributions, with PA respondents rating the “CNDS” label as more severe. Results suggest that a more medical sounding term (CNDS) may lead to attributions that this syndrome is a more serious, disabling illness. The policy implications of these findings are discussed.
