Post COVID-19 Neurologic Symptoms : a Somatic Spectrum Disorder ? (SOMATiC) (SOMATiC)

February 9, 2022 updated by: Centre Hospitalier de Saint-Denis

Neurologic Symptoms After Non-severe COVID-19 : Analysis and Diagnosis Assessment of Somatic Spectrum Disorder

A growing number of studies highlight the persistence of symptoms after the acute phase of SARS-CoV-2 infection, including in outpatients with mild to moderate forms of the disease. More than 80% of patients with persistent post-COVID-19 symptoms reported neurologic and neurocognitive disturbances. The pathophysiological mechanism is currently unknown, and several hypotheses have been put forward. Involvement of a Somatic Symptom Disorder (SSD) is plausible given the similarity of these symptoms with the Chronic Fatigue Syndrome identified as a SSD subtype. The objective of the SOMATiC study (SOMAtic symptom disorders Triggered by COVID-19) is to determine whether a positive diagnosis of SSD can be asserted in patients with persistent post-COVID-19 neurological symptoms.

Detailed Description

A growing number of studies highlight the persistence of symptoms after the acute phase of SARS-CoV-2 infection, including in outpatients with mild to moderate forms of the disease. More than 80% of patients with persistent post-COVID-19 symptoms reported neurologic and neurocognitive disturbances. The pathophysiological mechanism is currently unknown, and several hypotheses have been put forward. Involvement of a Somatic Symptom Disorder (SSD) is plausible given the similarity of these symptoms with the Chronic Fatigue Syndrome identified as a SSD subtype. The objective of the SOMATiC study (SOMAtic symptom disorders Triggered by COVID-19) is to determine whether a positive diagnosis of SSD can be asserted in patients with persistent post-COVID-19 neurological symptoms. The study includes consecutive patients referred for neurology consultation because of chronic neurologic symptoms after the acute phase of COVID-19. Data are collected with medical record and by phone interview. It consisted of a semi-structured interview followed by hetero-assessed scales. A positive diagnosis of SSD was established with all the following criteria: a PHQ15 score greater than or equal to 12 (criterion A); an SSD12 score greater than or equal to 23 (criterion B); an evolution of symptoms greater than or equal to four weeks for criterion C. To complete the DSMV criteria, the investigators assessed the presence of indirect argument in favor of SSD diagnosis : a traumatic experience of the initial episode collected during the interview, post-traumatic stress disorder measured by the IES-R scale, a psychiatric history collected during the interview, significant alexithymia measured by the TAS 20 scale, traits of pronounced perfectionism with the scale adapted by Cox et al. from HF MPS, chronic fatigue syndrome as described after viral infections with the SOFA scale, functional disorders prior to infection with SARS-CoV-2, a former and/or current medical nomadism, a significant consumption of care. The quality of life is measured by the WHOQOL-BREF scale, anxious and/or depressive symptoms measured by the HAD scale, and sleep disorders assessed by the ISI scale .

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

consecutive patients referred for neurology consultation to a referent neurologist in our center from may 2020 to may 2021

Description

Inclusion Criteria:

  • adults (18 years-old or older)
  • having had a mild or moderate COVID-19 managed on an outpatient basis during the acute phase of the infection
  • COVID-19 virologically confirmed or suspected on the basis of suggestive symptoms
  • spontaneously consulting for post-COVID-19 symptoms and referred for neurological advice in our center
  • with neurological clinical evaluation concluding that there is no differential diagnosis.

Exclusion Criteria:

  • patients who were hospitalized during the acute phase of the infection
  • suspected de novo neurological pathology unrelated to COVID-19
  • patient refusal to participate.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 22, 2021

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
