Lupus cerebritis after visiting a tanning salon

Area of Science:

• Immunology
• Dermatology
• Neurology

Background:

• Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with varied clinical manifestations.
• Patients with SLE often experience periods of remission and exacerbation.
• Ultraviolet (UV) radiation is a known environmental trigger for lupus flares.

Observation:

• A 53-year-old female with a 15-year history of stable SLE experienced a severe exacerbation after visiting a tanning salon.
• Initial symptoms included a cutaneous erythematous rash, followed by headaches, seizure, and psychosis within two weeks.
• The patient required intensive care unit admission for lupus cerebritis.

Findings:

• Ultraviolet A (UVA) exposure from tanning beds can modulate the immune system, triggering SLE exacerbations.
• UV light exposure is linked to the increased formation of antinuclear antibodies (ANAs).
• This case demonstrates that UV-induced lupus flares can manifest with severe systemic and neurological involvement.

Implications:

• Healthcare providers must educate SLE patients about the significant risks associated with artificial UV exposure, such as tanning salons.
• The potential for severe systemic and neurological complications underscores the need for stringent photoprotection measures in SLE patients.
• This case highlights the critical importance of a comprehensive patient history, including environmental exposures, in managing autoimmune diseases like lupus.
