Five-year Follow-up After Sars-CoV-2 Infection: Prevalence and Evolution of Post-acute Sequalae of COVID-19 (PASC) (PASC-5Y)

2026년 8월 11일 업데이트: Galluzzo Vincenzo, Fondazione Policlinico Universitario Agostino Gemelli IRCCS
This multicenter, observational, retrospective-prospective study aims to evaluate the prevalence and trajectory of Post-Acute Sequelae of COVID-19 (PASC) approximately 5 years after SARS-CoV-2 infection. The study will re-contact participants from an established cohort of more than 3,000 individuals with microbiologically confirmed SARS-CoV-2 infection, including both hospitalized and non-hospitalized patients, previously followed in dedicated post-COVID outpatient clinics. Participants will undergo a structured telephone interview approximately 60 ± 3 months after infection, and those meeting predefined clinical criteria will be invited to an in-person clinical assessment. The study will evaluate persistent symptoms, functional status, cognitive and nutritional status, frailty, sarcopenia, quality of life, healthcare resource utilization, and direct and indirect healthcare costs to characterize the long-term trajectory of PASC.

연구 인구

The study population consists of adults with a previous microbiologically confirmed SARS-CoV-2 infection who were enrolled in an established post-COVID cohort at Fondazione Policlinico Universitario Agostino Gemelli IRCCS (Rome, Italy) and Fondazione IRCCS San Gerardo dei Tintori (Monza, Italy). The original cohort includes more than 3,000 hospitalized and non-hospitalized patients followed after acute infection between April 2020 and September 2022. Eligible participants will be re-contacted and reassessed approximately 5 years after SARS-CoV-2 infection to evaluate the long-term prevalence and evolution of post-acute sequelae of COVID-19 (PASC), functional, cognitive, nutritional, and economic outcomes

설명

Inclusion Criteria:

  • Age ≥ 18 years.
  • Previous participation in the original cohort assessed at 6-12 months after the initial SARS-CoV-2 infection.
  • Persistence of symptoms beyond 3 months after infection, consistent with the WHO definition of Post-Acute Sequelae of COVID-19 (PASC).
  • Availability of clinical data related to the initial follow-up phase.
  • Provision of informed consent for study participation (for patients enrolled in the prospective cohort, informed consent will be obtained, while for retrospective participants, reference will be made to Article 110-bis of the Italian Privacy Code).

Exclusion Criteria:

  • Inability or refusal to complete follow-up procedures due to clinical, cognitive, or logistical reasons incompatible with the collection of essential study data.
  • Persistent inability to establish contact after multiple documented attempts.
  • Failure to provide informed consent.

Post-COVID Cohort
Adults with a previous SARS-CoV-2 infection enrolled from an established post-COVID cohort and reassessed approximately five years after infection to evaluate the prevalence and evolution of post-acute sequelae of COVID-19 (PASC), including clinical, functional, cognitive, geriatric, and economic outcomes.
다른: Post-Acute Sequelae of COVID-19 (PASC) Assessment
Observational assessment including telephone interviews, validated questionnaires, and clinical evaluations aimed at assessing the prevalence, evolution, and long-term outcomes of post-acute sequelae of COVID-19 (PASC) approximately five years after SARS-CoV-2 infection.

기간
Prevalence of Post-Acute Sequelae of COVID-19 (PASC) assessed by standardized symptom checklist.
기간: Approximately 60 ± 3 months after SARS-CoV-2 infection
The prevalence of Post-Acute Sequelae of COVID-19 (PASC) at approximately 5 years after SARS-CoV-2 infection will be assessed using a standardized checklist of persistent or newly developed symptoms compatible with PASC. The outcome will be reported as the proportion of participants presenting one or more PASC-related symptoms or clinically documented conditions.
Approximately 60 ± 3 months after SARS-CoV-2 infection

측정값 설명
기간
Severity of post-acute sequelae of COVID-19 symptoms assessed by Fatigue Short Form 7a
기간: Approximately 60 ± 3 months after SARS-CoV-2 infection.
Fatigue severity will be assessed using the PROMIS Fatigue Short Form 7a, a self-administered questionnaire assessing the severity and impact of fatigue. The score will be reported as a standardized T-score, with a mean of 50 and a standard deviation of 10. Higher T-scores indicate greater fatigue severity.
Approximately 60 ± 3 months after SARS-CoV-2 infection.
Severity of post-acute sequelae of COVID-19 symptoms assessed by Modified Medical Research Council Dyspnea Scale.
기간: Approximately 60 ± 3 months after SARS-CoV-2 infection.
Dyspnea severity will be assessed using the Modified Medical Research Council (mMRC) Dyspnea Scale, which evaluates the degree of breathlessness associated with physical activity. The mMRC score ranges from 0 to 4, with higher scores indicating greater severity of dyspnea.
Approximately 60 ± 3 months after SARS-CoV-2 infection.
Severity of post-acute sequelae of COVID-19 symptoms assessed by Perceived Deficits Questionnaire (PDQ-20).
기간: Approximately 60 ± 3 months after SARS-CoV-2 infection.
Subjective cognitive impairment will be assessed using the Perceived Deficits Questionnaire-20 (PDQ-20), a self-administered questionnaire used to assess perceived cognitive difficulties. The total score will be reported, with higher scores indicating greater perceived cognitive impairment. A PDQ-20 score ≥27 will be considered a predefined criterion for further cognitive assessment with the Montreal Cognitive Assessment (MoCA).
