# Unmasking Hirata: a mysterious case of Hypoglycemia triggered by immunologic storm

## TL;DR

A 35-year-old woman with a history of autoimmune issues developed hypoglycemia after an allergic reaction, linked to an autoimmune condition called Insulin Autoimmune Syndrome.

## Contribution

This case suggests that broader autoimmune processes may be involved in Insulin Autoimmune Syndrome presentations.

## Key findings

- Hypoglycemia in the patient was confirmed to be caused by insulin autoantibodies.
- Immunosuppressive therapy significantly improved the patient's condition.
- The case implies a potential connection between allergic reactions and autoimmune processes in IAS.

## Abstract

We report a rare case of Insulin Autoimmune Syndrome in a 35-year-old woman with prior autoimmune features who developed hypoglycemia after an allergic reaction. Diagnosis was confirmed by insulin autoantibodies. Immunosuppressive therapy yielded significant improvement. This case suggests a broader autoimmune process may underlie seemingly isolated IAS presentations.
