Abstract
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disorder
with variable disease courses and multiple clinical manifestations
[1]. The etiology of SLE is not clear, but different environmental
(ultraviolet [UV] light, infections, drugs), genetic, and hormonal
factors all seem to be involved [1]. Positive family history and
history of having other autoimmune illnesses are considered high-risk
factors for SLE, but most SLE cases are scattered [1]. The 2019
EULAR/ACR classification criteria for SLE include positive ANA at least
once as a mandatory entry criterion; followed by additive weighted
standards grouped in seven clinical (constitutional, hematological,
neuropsychiatric, serosal, musculoskeletal, renal, mucocutaneous ) and
three immunological (antiphospholipid antibodies, complement proteins,
SLE-specific antibodies) domains, and weighted from 2 to 10, and
patients accumulating ≥10 points are classified to have SLE [2].
Herein, we report this case of neuropsychiatric lupus as it is uncommon
and is a severe form of SLE.
