详细描述

Spontaneous international multicenter retrospective and prospective observational study which objective is to evaluate the prevalence and risk factors of persistent SARS-CoV-2 infection within a population of hematology patients with humoral immunity deficiency.

The retrospective recruitment period will span from January, 1st, 2022 to the date of authorisation by hospital directorates following the Ethics Committees' approvals. This period has been established considering the prevalent diffusion of the omicron variant and its subvariants, which has led to significant changes in the clinical manifestations of COVID-19. The prospective recruitment will be carried out over the 12 months immediately following the retrospective period. During the study period, screening for persisting SARS-CoV-2 infection and therapeutic management of all patients will be carried out by the attending physicians according to routine practice.

This study is enclosed in the EU Horizon 2020 project "Connecting European Cohorts to Increase Common and Effective Response to SARS-CoV-2 Pandemic: ORCHESTRA" (Grant Agreement No. 101016167) and is located within Task 4.6 "Prevalence, risk factors and therapeutic management of persistent COVID-19 in frail patients." It is expected to enroll approximately 1,000 patients (500 at the coordinating center).

结局指标

主要结局

Prevalence of persisting SARS-CoV-2 infection among immunocompromised patients

时间窗: Retrospective recruitment period will span from January 1st, 2022 to to the date of authorisation by hospital directorates following the Ethics Committees' approvals

The first primary endpoint variable will be the rate of patients with persisting SARS-CoV-2 infection among study patients with new diagnosis of SARS Cov2 during the study period Persisting COVID19 will be defined as the persistence or the recurrence of symptoms and signs (fever, dyspnea, hypoxemia, changes on chest-X ray or CT scan) and positive SARS-CoV-2 PCR ≥ 21 days after the time 0 (day of the first test positive for SARS-CoV-2 infection)

次要结局

  • Risk factors for persisting COVID19(Retrospective recruitment period will span from January 1st, 2022 to to the date of authorisation by hospital directorates following the Ethics Committees' approvals)
  • Re-infection within 120 days(Retrospective recruitment period will span from January 1st, 2022 to to the date of authorisation by hospital directorates following the Ethics Committees' approvals)
  • Duration of viral shedding(Retrospective recruitment period will span from January 1st, 2022 to to the date of authorisation by hospital directorates following the Ethics Committees' approvals)
  • Duration of symptoms(Retrospective recruitment period will span from January 1st, 2022 to to the date of authorisation by hospital directorates following the Ethics Committees' approvals)
  • Prevalence of imaging alterations(Retrospective recruitment period will span from January 1st, 2022 to to the date of authorisation by hospital directorates following the Ethics Committees' approvals)
  • All-cause 120-day mortality(Retrospective recruitment period will span from January 1st, 2022 to to the date of authorisation by hospital directorates following the Ethics Committees' approvals)
