Diversity in Acute Autoimmune Pericarditis: Nationwide Analysis of In-Hospital Outcomes and Recurrence.

ABSTRACT:

Background

Acute autoimmune pericarditis (AAP) is an uncommon disease with diverse etiology. Data regarding AAP diagnosis and outcomes are scant.

Objectives

This study sought to describe the diagnosis and the rates of in-hospital mortality, cardiac tamponade, and readmission of AAP.

Methods

This study used a nationwide Japanese claim-based database to identify patients with AAP from April 2016 to March 2020 compared with patients with acute idiopathic pericarditis (AIP).

Results

Of 20,469 hospitalized patients with acute pericarditis, 170 had AAP and 5,027 had AIP of new onset. The diagnosis for AAP was systemic lupus erythematosus in 23.5% (40 of 170), rheumatoid arthritis in 19.4% (33 of 170), systemic sclerosis in 8.2% (14 of 170), other in 17.7% (30 of 170)
