Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study explore the relationship between COVID-19 and the induction of autoimmune diseases.

This study comprises both retrospective and prospective components. The retrospective arm (2016-2019) was conducted to establish baseline incidence rates of autoimmune diseases (AIDs) prior to the COVID-19 pandemic. The prospective arm (2020-2024) involves the identification and longitudinal follow-up of newly diagnosed AID cases to evaluate disease progression, therapeutic response, and recurrence. Based on these data, the study will yield four distinct analyses:

1. trends in AID incidence before and after the COVID-19 pandemic,
2. the demographic and clinical profile of AID patients in the post-COVID-19 era,
3. the association between COVID-19 vaccine status and the development of AIDs, and
4. the clinical course, response to therapy, and long-term outcomes of AIDs in post-COVID patients compared to pre-pandemic cases.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

It has been suggested that the shared pathogenetic mechanisms and clinical-radiological aspects between the hyper-inflammatory diseases and Covid-19 may suggest that SARS-CoV-2 could act as a triggering factor for the development of a rapid autoimmune and/or autoinflammatory dysregulation, leading to the severe interstitial pneumonia, in genetic predisposed individuals.

The study is designed to investigate four primary objectives:

1. the incidence and trends of autoimmune diseases (AIDs) before and after the COVID-19 pandemic,
2. the association between COVID-19 vaccine status and the development of AIDs,
3. the clinical progression, treatment response, and recurrence of AIDs in post-COVID patients, and
4. the demographic and clinical profile, contributing factors, and spectrum of AID types identified during the post-pandemic period.

Retrospective data from 2016 to 2019 will be analyzed to establish baseline incidence rates, while prospective data from 2020 to 2024 will focus on new cases, vaccine exposure, clinical course, and patient characteristics.

The investigators hypothesize that:

1. the incidence of AIDs has increased in the post-COVID-19 era compared to the pre-pandemic period,
2. there is a positive association between COVID-19 vaccination and the onset of AIDs,
3. the clinical course and therapeutic response of AIDs in post-COVID patients differ from historical cases, and
4. unique demographic and clinical patterns characterize AID cases arising during the post-COVID period.

Accordingly, the study will yield four distinct analyses, each to be reported in a separate manuscript corresponding to the above objectives.
