Adult-Onset Still’s Disease Associated With Hyperimmunoglobulin-E: A Case Report

TL;DR

A middle-aged woman with a rare inflammatory disease showed high immunoglobulin-E levels and responded well to prednisone treatment.

Contribution

This case report highlights a rare association between AOSD and hyperimmunoglobulin-E without allergic or parasitic causes.

Findings

The patient had AOSD with very high immunoglobulin-E levels.

She responded well to prednisone treatment.

No history of allergic disease or parasitic infection was found.

Abstract

Adult-onset Still's disease (AOSD) is a rare, chronic, multisystem inflammatory disorder of unknown etiology. Diagnosis is made clinically and can be challenging. AOSD typically affects young adults but can occur in older patients. The association between AOSD and very high immunoglobulin-E levels (also known as hyperimmunoglobulin-E) is not well studied. In this report, we present the case of a middle-aged woman with AOSD who presented with more than two weeks of fever, severe generalized weakness, and sore throat, and responded very well to prednisone. She was found to have hyperimmunoglobulin-E without a history of allergic disease or parasitic infection.
