Systemic Lupus Erythematosus Flare Triggered by Mosquito Bite Manifesting as Febrile Targetoid Rash

Area of Science:

• Immunology
• Dermatology
• Rheumatology

Background:

• Systemic lupus erythematosus (SLE) is a chronic autoimmune disease.
• Disease flares in SLE can be triggered by various factors.
• Atypical rashes, such as targetoid rash, can occur during SLE flares.

Purpose of the Study:

• To highlight insect bites as a potential trigger for SLE disease flares.
• To emphasize the occurrence of atypical targetoid rash in SLE patients experiencing insect bites.
• To underscore the importance of identifying and preventing such triggers in SLE management.

Main Methods:

• Literature review on SLE triggers.
• Case study analysis of patients presenting with SLE flare post-insect bite.
• Dermatological and immunological assessment of affected patients.

Main Results:

• Insect bites were identified as a significant trigger for SLE disease exacerbation.
• Atypical targetoid rash was observed in a subset of SLE patients following insect bites.
• Prompt recognition and management of insect bites can mitigate SLE flare severity.

Conclusions:

• Insect bites represent an under-recognized trigger for SLE flares.
• Awareness of insect bites as a trigger is crucial for SLE patients and clinicians.
• Preventive measures against insect bites are essential for effective SLE disease control.
