Ten patients (9%) developed the JHR.
No patients experienced an allergic reaction to penicillin.
The JHR occurred less frequently than in previous studies.

6 days after treatment, the patient was found more irritable and was unable to fall asleep at night.
On the seventh day, worsened magnetic resonance imaging (MRI) abnormalities in the bilateral medial and anterior temporal lobes were unexpectedly discovered.
We consider that these transient and slight mental symptoms may be associated with the transiently worsening phenomenon in cerebral MRI findings during the early period of treatment with penicillin.
This indicates that some nonspecific inflammatory process has happened in the early stage of treatment, which necessitates the use of corticosteroids after the occurrence of systemic or mental symptoms.

The patient described feeling cold with worsening headache and chills approximately one hour after infusion of the first dose of penicillin.
On examination, rigors, shallow inspirations, and chills were noted.
He was afebrile, tachycardic, and tachypneic and had an oxygen saturation of 94% while breathing room air.
Initially, this reaction was thought to be a result of a drug allergy, but upon further review, we determined that it was JHR.
It is not uncommon to confuse drug allergy with JHR.

JHR often occurs with the treatment of spirochete infections. However, the mechanism by which the reaction takes place is not clearly defined.
Studies suggest with conflicting evidence that the JHR is caused by release of endotoxin-like material from the spirochete as well as cytokine elevation in the body.
